Feelings twist into forbidden passions, and the lines between familial love and sexual pleasure blur.

Prologue

In the midst of the pandemic, I was finishing up my Masters when I both lost both my job and my apartment. I had already planned to come home from school over the winter break, but I wasn't expecting to have to come home with literally every possession I owned in the back of a U-Haul -- my girlfriend Siobhan and I taking turns at the wheel on the long icy trip back, both of us pretending that we weren't anxious about our living situation. I could keep my stuff in the garage and Siobhan and I would stay in my old room over the winter, giving us some time to figure out what we wanted to do next.

I'd only met Siobhan near the end of the summer on Hinge, a place I wasn't expecting to meet anyone worthwhile, but we had unmistakable chemistry and I knew that I wanted to make it work. Siobhan might not have been the sort of person you'd see on a swimsuit magazine with her alt-emo fashioning and slight figure, but she was incredibly striking with her dark hair and tan skin, blue eyes, and a pout on her lips that never really went away. For the entirety of our first date, about 90 minutes of walking and small-talk in the park, I could feel incredible tension between the two of us. A few kisses that day, a few drinks the next, and we became inseparable.

Things were different. She had given up her room in an apartment of 12 different students to join me on the lease just a month before we got evicted -- shit timing but I thought my landlord would be cool and that my work program wouldn't be impacted by the pandemic. You make plans, god laughs, right? Speaking of, this wasn't quite the end of the troubles.

December 13, 11:00PM, a gas station roughly 120km away from my parent's house

"Listen, Sig, I'm sorry but I won't be there to welcome you and Siobhan when you get in tomorrow."

"That's okay mom, you really don't need to apologize. I heard about the spike in cases, so if you and dad are working a double tomorrow I can just start getting settled in with Siobhan, maybe cook a roast-something for when you guys come home?"

"I kind of buried the lede. It's actually a bit more than a double, Sig. The board wants to send both me and your father to Copenhagen."

"Copenhagen, like in Denmark? Why?"

"That's the one, and I'm honestly not entirely sure yet. Do you remember me telling you that our hospital and its research teams are all owned by a medical firm in Copenhagen? They're looking for two researchers to bring in to a new development project, and they decided that your father and I are the best candidates."

"Damn," I muttered away from my phone, before taking a deep breath and putting it back to my ear. "Well that's too bad, I was looking forward to you getting to meet Siobhan." I couldn't be mad at them. They were saving lives, and they also did not get much of a say when it came to matters involving the board, but with my living situation and work issues I knew I needed some family support.

"I know, we were too." a moment of silence between us "You and Siobhan won't be alone over the holidays, at least."

"What do you mean?" My face was already turning to a smile. I was pretty sure I knew what she meant.

Siobhan was curled up against the passenger-side door when I got back in the U-Haul, nose in a book, eyes half-open, wrapped in a heavy acrylic blanket that had served us well on our journey over. As I got behind the wheel, she placed her dog-eared softcover of Milton's Paradise Lost on the dash and wrapped her arms around my neck, planting kisses behind my ear.

"Took you long enough. I was starting to get chilly." She whispered through a smirk.

"Hmm, well we wouldn't want that now, would we?" I whispered back to her as I traced out the shape of her thigh with one hand, the other running through her hair. "We'll need to backtrack a bit if we want to get a room before midnight, the next motel is nearly in the next town over, but there was one 5 minutes back."

She bit my ear. "So you just want me for my body then? Such a rush to get me in bed." She pushed herself back from me in mock offense, the smirk still visible as it fought her efforts to hide it from her face.

"Oh no, I plan to take a lot more than just your body." I said, tightening a grip on the hair between my fingers, the effort pulling her head back towards my hand, now curled in a fist. "Is that not what you wanted?"

"I should have expected as much from a brute." She gasped out, her breath humming with excitement. She caressed my arm that held her in place, lightly scratching the skin. "I told you on our first night together," She pivoted, her right leg outstretching, ball of her foot gently pressing against the crotch of my jeans. "That I wanted you to take what you want."

I grinned and brought her face to mine, still with a grip upon her hair. "Let's find a bed," I said between kisses, feeling her smile on my lips.

On the road, I tried to let my erection calm down some in preparation of having to book a room. Seeing only the fluorescent lines on the road in the pitch dark helped me focus a bit, and I suddenly realized that in my lust, I had totally blanked on telling my girlfriend about the major change to our living arrangements.

"Uh, that was my mom, by the way. She and dad have accepted a position out of the country, and I don't think they'll be back for a while. Probably not before the new year and maybe not before classes start."

"Oh woah." Siobhan looked at me. "That's too bad. You know I was really looking forward to meeting them, and I know you wanted some time with them this winter. How are you feeling about it?"

"Well I'd be lying if I said I was happy about it, but I understand the situation and it was always like this growing up. Hard to stay mad at people who are saving lives, and they're always attentive when they're around." I paused for a moment. "We won't be alone though, you'll actually have a chance to meet my sister. She will be staying at my parent's place too."

"That's lovely, Sigurd! How long has it been since you've seen her?"

"Two years now." My sister, Emma, was an overachiever. Despite being a year younger, she was incredibly accomplished, having spent two years as staff in the office of the Climate Secretariat of the UN and completing her masters all the while. I was always the artistic older brother, and my study in literature and artifact restoration was admittedly not as flashy at family gatherings as oceanic and atmospheric science applied to policy work. I wasn't bothered by it at all, I liked being the boring sibling. Emma and I texted back and forth every once and a while, but had admittedly lost touch. Both of us were so entrenched in work, and the pandemic had made both of our respective situations much more tense.

There was also a moment two years ago, in the winter before the pandemic that I'd not thought about for a long time, but the shadow of the memory seemed to close in around my vision as I stared into the seemingly endless night ahead of me, the lines of the road disappearing in the blackness.

"That's a long time." I jolted, vision and mind snapping back into focus at Siobhan's words. Unstrapping herself, Siobhan moved closer to me, laying her head on my shoulder. "I think we're going to have a lovely Christmas holiday, Sigurd."

"I agree." I leaned in to kiss her forehead as she nuzzled up to me, still uneasy over something that I couldn't quite place. A memory I was choosing to not think about.

December 14, 10:32AM

Siobhan and I got into the truck early the next morning, both shivering a little due to our freshly-showered hair. I wasn't only feeling a bit wiped from the driving yesterday, but the second we got into our room we had fucked for nearly an hour before passing out in a pool of sweat and bodily fluids. The hurried shower that we just barely snuck in before checkout time did little to rid our bodies and clothes of the scent of sex. Siobhan wore a surgical mask, something she'd taken to doing regardless of any worry of contagiousness, but to keep warm when her face got cold. I hated the masking, my beard made me overheat almost immediately, but I always thought that she looked cute when she wore it. Her eyes and brow, naturally sloping into a furrow, gave off a very sexy cold demeanor when you couldn't see the rest of her face, something that I couldn't really explain my attraction to. What's worse is that she knew it, and she delighted in teasing me.

I once again kept my focus on the road. We could screw again once we got back to my old room at my parents' house.

December 14, 2:05PM

"Okay, I feel kind of like a dumbass, I hope I don't need to break a window."

I scrounged around the front stoop, the spare key no longer in its reliable hiding spot underneath the door mat. "Not under the planter either," I grunted, on one knee making sure I hadn't missed it "Or the gnome. Fuck. I should have asked my mom if she'd changed the hiding spot. I can't believe that I packed away the house keys."

"Babe, I think that I saw a light turn on, is it possible that--" Siobhan stopped as the front door swung inwards.

As I got back up on my feet and dusted off my knees, I saw my sister looking right at me from the doorway. Not a hair over 5 feet tall, with light blonde hair and an even slighter build than Siobhan's, Emma's presence was inimitable. Even if it weren't for the warmth coming from indoors, I could feel what felt like sunlight radiating from her on my skin.

"Emma! Mom didn't think you'd get in until later this week!" I exclaimed, picking her up in a bear hug as she let out a squeal of delight and surprise at her sudden airborne nature.

"Hey, put me down, I'm trying to make a good first impression here!" Emma laughed as she pushed me away and I gently let her down. "Sucks that mom and dad couldn't be here to greet you, mom had to fly out right after your call and you just missed dad. Dad almost forgot to tell me you'd be bringing your girlfriend home before he left, I can't believe you were going to let them meet her before I did."

"Oh we might have even passed him on the road, then. And yeah, that's very typical of them to forget to mention something like that." I parted from Emma and turned around. "This is Siobhan, my girlfriend." I turned to see Siobhan's expression of absolute shock. Putting a hand to the mask's ring around her ear and letting the cloth fall from her face, I saw that Siobhan's mouth was actually agape, and she clearly needed to make a conscious effort to close it and gulp down a bit of air.

"Shiv?" I heard from my sister behind me.

"Shiv?" I repeated. Feeling out the syllable, still not quite making the connection. They knew each other. Why, oh god, why, did they know each other.

"Hey Emma." Siobhan was clearly struggling with something, and that something turned out to be a smile. "Been a while!" The words were more enthusiastic than the actual tone. Embarrassment, genuine friendliness, familiarity, but distance were all within that tone.

The three of us stood there for what felt like an eternity. I turned from my girlfriend to my sister.

"I'm getting the impression that you guys...?" not really posing a question of my own, so much as reiterating the question that we all could hear carved in the silence of the windless winter air.

"We actually... dated for a bit." Emma's words seemed to fall from her mouth with the same gentle percussion as the snowfall that began from when we left the hotel earlier that morning.

"Gotcha." The wrong response. But silence makes me uncomfortable, and even thinking it over now it seems like the least-bad of many worse options that were running through my head.

"Did mom and dad leave us any coffee? Let's put a pot on."

--

We all stood around the island in the kitchen, letting the drips of the coffee maker dictate the tempo of our thoughts.

Okay, they dated. What the fuck now? We're all going to be living together, Siobhan -- Shiv? -- used to date my sister. Okay, so this was fucking crazy, right?

I may have left out some details about my sister. Didn't seem relevant and I'm a progressive guy, but Emma is a gold-star lesbian and has known it since we were kids. Her and I really grew up close, and I was probably the first person that she told, but she has never been ashamed of who she was and was open with her interest in other girls. This got her some bad attention growing up. Usually just teasing and some awkward confessions to straight girls, but it did once escalate.

Back in high school, a meathead my age named Kai found out that his ex-girlfriend had begun dating my sister, went on a homophobic screed and tried to beat Emma, and from what I heard he planned to do more. He was unlucky that his friends weren't willing to be accomplices in this, and that he had been a bit too vocal about where and when he would jump her. I found him in the girls' changing room, standing over my sister, half of her gym shirt ripped off in his hand. I remember very little of what happened next, but I remember her visage, steeped in fear, immediately light up when she saw me. Part of her face was red where he had slapped her, and there were claw marks on her chest that were deep enough to draw blood from her breast. That sunlight from her face and relief in her eyes pierced my heart, and I flew into a rage the likes of which I had never felt before and likely never will again.

I got into fights regularly in high school, but that was the one that almost got me in trouble with the law and could have changed the direction of my life. I've always been protective of Emma is I guess where I'm going with this, and now I was afraid that I had really, really hurt her.

"Okay, so for the record we left each other on good terms." Siobhan broke the silence first. "Right?"

Emma nodded.

"That's... well I suppose that's a relief." I said, moving to the newly-brewed pot of coffee, beginning to pour out cups for each of us. "How did you two meet?" Christ.

Emma seemed to be more upright now, prepared, if not ecstatic, to explain. "Right before I went to work for the UN, I was working for that restorative tree-planting service. Shiv-- Siobhan," She corrected herself, "was one of our volunteers. We ended up hanging out a lot during the fall semester, and when we met back up in the new year, right before the pandemic, we dated a bit. The UN placement was abrupt, so we parted ways pretty quickly."

This still felt bad. I couldn't tell if there were more feelings there that my sister was leaving out. My sister fucked my girlfriend, also, I fucked her ex-girlfriend. Let this be a nightmare or let me immediately perish out of sheer awkwardness, please.

"We both knew it would be tough to stay connected, and you know I don't use social media, Sigurd, so I guess I had never seen a photo of either of your families--your family--together." Siobhan covered her face in embarrassment, and I saw that Emma's eyebrow raised when Siobhan called me by my full first name. "I honestly don't know what to say. I'm going to hang out in the U-Haul in the garage for like 5 minutes to enjoy this coffee and maybe read a bit of my book and pretend that I'm fine and that this is all normal."

We all were silent as Siobhan left the kitchen pensively, hands both around the mug.

I looked at Emma. She was deliberately looking away from me, until suddenly she pursed her lips, and turned with an impertinent frown, half playful. "I don't buy the social media excuse. Mom said you met your girlfriend in August, so what, you never talk about me?"

"I guess I never said where you studied for your undergrad, but Emma is a super common name, and did you not tell her you were going to work for the UN?" I smiled, thankful that our sibling dynamic was still intact, if not more than a bit strained. "I brag about you all the time, you work for the fucking climate secretary or whatever. Meanwhile, you know what isn't a common name? Sigurd. Most kids don't have a nerdy-enough father willing to name their son after a literal mythic dragonslayer. Did you not mention me?"

"Secretariat, and I know you know that's what it's called. I might have just said I was going to work in politics in New York, but that was because it's technically a confidential placement until you're public facing and not at all a lie. Also, since when have people called you Sigurd? You've literally always been Sig." She smiled at that last word, but a brief frown crossed her face. "I bragged about you too."

"New school, full name. I've been Sigurd since I began the program. I'm less embarrassed of it now, which from what I recall, is something you once teased me over, no?"

"It takes just a bit of teasing to get you to change your name?" She smiled again, sensing weakness. We were both leaning against the island in the kitchen, coffees in hand. I realized how long it had been since I'd seen her. The occasional updates on her life I'd gotten gave such an insignificant impression compared how much she had changed and matured when I looked at her now.

So much had changed. "I like the long hair by the way, that's a new look on you." I said without really thinking of it. She was always able to pull off some pretty insane haircuts, but this was one of the few times since we were kids where her hair fell below her neck.

"Thanks," she smiled, I guess also having a moment to process how long it has been, and how this style she'd adopted while away was totally new to someone she'd known her whole life. "But you're changing the subject. Are you cool with this?"

"Cool with..."

"You are not allowed to pretend like this isn't weird. It's fucking weird. I think I can be fine with it."

"I agree that it's weird. But, seriously, just like that, you know that you're fine with this?"

"Well I already know her, Sig. I know she's a nice person, and I don't want to kill your love life. I've dated people for a lot longer in the time since Shiv and I broke up, and dad told me about how much you gush about this girl. Dad thinks that you've already said that you love each other."

"Well we actually haven't yet."

"Yet? Do you think that might be something that you will eventually say?"

"I don't know, Emma. I might have known yesterday, but this has been a hell of a morning and I'm worried that Siobhan won't be cool with this." I grimaced, coming to grips with the truth in my words.

"She'll probably be fine," Emma gazed into the distance, contemplative. A silence came over the room again, and something about Emma's expression, not necessarily one of joy but one of... something I couldn't put my finger on, made me feel that sunlight again.

Before I could stop myself, my eyes danced down to Emma's shirt. It wasn't cold inside, but I could clearly make out the outlines of her nipples. She was almost flat chested, with but a slight curve of her breast and slightly-wider-than-average hips to flaunt her femininity. I could just see those breasts now, as they lifted the shirt fabric below them. Gravity made them perk away from her ribcage as she breathed in and out.

"Sigurd?" I snapped to attention, realizing that I had been staring for far too long, although I was unsure exactly how long. Emma gave me a look of concern. "I am sure that she wants you to be happy, and I do too." She held out her hand, and our fingers interlaced for the first time in two years.

--

The windows were down on the U-Haul to let the heat in from the garage, Siobhan leaning against the passenger door, once again wrapped in a blanket and reading Milton. This time, eyes fully open and aware, reading from the pages like a rag soaked up spilt wine.

"Hey." I said before opening the driver's side door.

"Hey." She said back.

"So--"

"No, I can start." She kept looking at the book. "I'm sorry about this, I didn't know you two were siblings. I... fuck, okay, nevermind. I still don't really know what to say." She began hiding her face, fully now, between the book covers. I slid over to her.

"You didn't do anything wrong, Siobhan. And Emma is not mad at you or me from what I can tell, so please don't apologize again."

"How is that even possible? Not being mad at you, I get, but why isn't she mad at me?"

"She said that it was a long time ago, and she says that she already knows you're a good person."

"Ugh. What sucks is that I totally see how you two are related now. You're both way too accommodating. At least pretend to be mad so that I don't feel like I'm being a paranoid and anxious crazy person."

"You'd rather that we be mad so that you'd be vindicated in your anxiety that we might be mad at you?"

"Yes."

"Okay, well, too bad, but I'm not. I think we can work this out. It's basically been two years since we've all last seen each other," Siobhan nodded cautiously, waiting to see where I was going with this.

"Why can't we start fresh? I don't mean that we'd pretend like you two never dated, but my sister has said that she wants both of us to be happy, and essentially gave us -- permission. If we all accept this, are you still able to be with me?"

"Be with you?" Siobhan began to cry. "I don't know what I would do without you. That's a stupid question." I began to tear up a little as well but couldn't help but chuckle a bit at her outburst, and she finally moved towards me out of her blanket cocoon. She still smelled like sex.

"Two years since we all saw each other, huh?" She spoke softly as she lay her head against my chest, as if only speaking to herself.

"What?"

"Time is just a funny thing, Sigurd."

December 14, 3:55PM

"So, we're cool, but she's going to spend a couple nights in a hotel."

"Why?"

"She said she needed space."

"Okay, fair enough." Emma quirked her head, questioning. "And you're cool with that?"

"Let's go with 'moderately' cool with that." I grimaced a bit "I think some space might actually be a good idea, we've been on the road, stressing over the prospect of not having an apartment to come back to in January. She's staying at a place that does massages and spa treatments and I do not begrudge her trying to destress a little.."

"Okay then. Great. Told you she'd be fine with it. Want a beer?"

"It's December, Emma, have some class. Bourbon and eggnog during daylight hours, cold booze in the evenings. You know this."

Emma pointed me to the cabinet above the fridge. "Fine, but I'm not tracking down a step stool to get the liquor. Fetch, tall man."

Hours later, we had done nothing but catch up on our studies and our work. My part-time job as an archivist was actually of genuine interest to Emma, who, like me, had an affection for classics, and her job was a never-ending list of tragedies and miracles that made me so glad to be in the humanities, far away from politicians and important people. No one deserves to have a life this interesting, and I say that with solemnity.

"But you're fucked now, right? They aren't renewing that position, dad said."

"Yeah-- Kind of a brutal way to put that, but an accurate read of the situation."

We were on the couch in the living room: a space yet undecorated for Christmas but still giving a palpable sense of cheer. Our childhood home was massive, something I never appreciated before I started living in shoebox apartments suitable for poor grad students.

"Well I don't want to beat around the bush, this is your life. Do you think they'd let you study remotely?"

"They might. I sent the request off when I realized we needed to move out, but it might be a bit before I hear back. It is actually enough time to find a place, but both Siobhan and I agree that it makes sense to try to work a semester here, save cash and then I'll be able to find full-time work if we move back because I'll have finished my masters. Her department actually gave the green light before we left."

"You two are good together."

"You haven't seen a lot of us together yet. You sound pretty confident."

"I guess it's just a hunch, and after all, I knew both of you before you met each other." Emma blushed at her own words, and stammered out "That was maybe a bit too soon, sorry. Let's watch a movie."

"It's fine," realizing I also felt my face heat up at the thought of my sister and my girlfriend together. A body that I knew so well caressing one that I wasn't allowed to know at all. And yet, I could see the exposed nape, quivering in pleasure, pale and slightly tanned breasts pressing against each other, a shape that I had never seen but knew so vivi--

"What should we watch?" I said.

December 14, 10:31PM

I can't remember what the actual title of the movie was. I didn't listen to a word of the dialogue. It was an older film but every frame was striking. Soldiers in uniform, verdant pastures, period costumes and candlelight. I was sitting at the end of the couch facing the TV, Emma lying down the length of it, both of us wrapped in our blankets. We hadn't lit the hearth and the living room didn't get the most out of the heating system so it was starting to get a bit chilly.

"It looks much warmer in those fields than here." Emma mumbled to herself, unconsciously tucking the blanket underneath her body to keep in the warmth. She turned to me then, a questioning and sly look on her face.

I looked back in utter befuddlement. Bourbon, and now red wine, had influenced our manners of thinking, and I didn't see what was so amusing. I soon felt it, as Emma practically lept on me, landing her back directly on my chest.

"Oof!"

"Some mythic dragonslayer." She gathered up our blankets both, and I begrudgingly let her into my own curl of cotton and wool.

The film continued. The hero fumbling and making mistakes over and over, eventually finding himself in positions of power before swiftly failing his way up once more.

Having Emma so close to me did actually keep me much warmer than before. I begun to sweat slightly, and as I noticed that I was beginning to sweat, I once again recalled the scent of sex on Siobhan as we kissed just hours ago. You don't ever smell it on yourself, but people around you can pick it up. Especially when it's so warm and you're so close. I tried to read an expression of -- I don't know what kind of expression I was looking for exactly -- off of Emma's face to see if she noticed. Her porcelain skin almost reflected the vivid colors coming off of the TV. Greens and Reds, Whites and Oranges, and eventually the deepest shade of blue. The hero was approaching an object of his affection, a beautiful woman, and they embraced and kissed without a word. Looking down at Emma's face, I saw that beauty reflected completely, a statue of pure grace and tender love carved from flesh.

I recalled a memory that I'd made myself repress in my active mind.

Two years ago, on a couch like this one in my old apartment, early January. Emma's face, contorted in an expression that you should never get to see on a relative, was but an inch from mine, her breath on my lips. We were both naked, staring each other in the face. I was inside her, my hands on her plump ass, pumping deep, hearing moans and cries of passion from my sister. I was again an animal, but one that could not be forgiven. Turning over and laying her beneath me, I relished in the taboo and let my lust control me. She came on my cock over and over, never breaking eye contact but to readjust, and mouthed words to me that I couldn't understand but saw the emphatic agreement of lust in her own dark eyes.

I remember having enough presence of sense that I pulled out, cumming over her abdomen and on her labia. I saw it glisten on her and drip down her form. I can't remember how it started, and I can't remember what happened next or how we agreed to never speak or think of it, but I saw that as we both were panting, staring at each other, my sister picked up a bead of my semen and placed it on her tongue. This was a memory that I'd locked away. The shadow that clouded my vision on the drive here.

I felt her breath on my face again.

Emma was looking up at me, breathing a little heavier than normal, and the spell was broken. I realized that my own sister's hand was not but an inch away from my erection, and that I had been so consumed by lust that I had only just noticed it.

"You look angry," she smiled. "Is it that bad of a movie?"

What expression did she have on her face before she smiled just now, when I was lost in that memory? I can't remember.

"No, I like the movie. I am getting a bit sleepy though." A half-truth, I do have a scowl when I get tired. But I looked angry? I suppose it's better than being found out for having thoughts like that. Remembering thoughts like that. With my sister.

"Oh, okay, I suppose we can find some time tomorrow?" She seemed to have more energy than me but was mostly nonplussed by the proposal.

"Yes." I did actually like this, and could have stayed up later. But I was afraid of what I was feeling, and recognized that there was a point of no return that I had once passed, swore never to do so again, and was inching ever closer to that marker now fully aware of it.

December 15, 1:05AM

We turned in for the night. My room was exactly as I had left it. Pretty sparse aside from a few posters I'd picked up throughout the years and some obscure memorabilia on a shelf.

I couldn't sleep. A little bit too much light glinting through the window than I was used to, and my guilt over my sexual interests and histories with both my girlfriend and sister was preventing me from drifting off.

So I got up to take a leak and drink some water. On my way back to my room, I heard something from across the house. The faintest of static could always catch my attention, and I realized I hadn't turned off the television. The television was on, but it wasn't paused on the frame of the film Emma and I were watching, and I don't think she'd continue it without me.

Emma was in her pajamas, sitting where I had been sitting with her earlier on the couch. She had headphones on, and as I was about to call her name, I realized what she was watching.

Her hand was between her legs, pajama bottoms dropped to her knees. She was caressing and tweaking one of her nipples, her shirt pulled up to her neck. I was enraptured by this sight. Once before I had seen this exact face in this exact form, but I had forgotten its true power over me. I put down my water, and began to stroke in rhythm with my sister.

As I pleasured myself to this sight before me, I fully downloaded what I was seeing on screen. There were beautiful naked women, with their lips wrapped around-- cocks? I was still not fully processing what was happening. I guess that she was technically not a gold star lesbian, but this was still a lot for me to take in. The women on the screen, silent to me thanks to her headphones, were clearly begging for something. While I couldn't say for sure, an educated guess would be that they were asking for what they ended up receiving. Spurt after spurt of cum flowed into their mouths, their tongues outstretched, making an effort to grab it from their cheeks when the cock wasn't aimed right. The girls showed it off to the camera before new models entered the frame, eager to suck more cum out of a seemingly endless supply of dicks.

Emma began to climax, and I felt it coming on just as quickly. Her moans and gasps turned to a quiet shriek that I could feel in my balls. My mind went blank as I let myself shoot my load to Emma's sounds and the sight of her tits, pussy covered from my view by the angle of her arm. I could feel it all over again, pulling out from Emma's hot pussy to cum all over her abdomen, seeing her daintily licking up a drop of my cum.

And like that, I was back. Clarity. Oh shit my cum is everywhere. Oh my god I jerked it to my sister. Fuck, the ceiling? I heard a rustling and froze.

Emma had turned over, lying in place, letting her pants stay down at her knees. Facing away from me now, she held up the remote to the TV and turned it off. I guess she just got in today too, and didn't care to move. Finally some stellar luck. I took off my shirt, being as quiet as possible but still pretty sure that she had her headphones still on, and wiped up as much cum as I could find. Even the bit on the ceiling.

I slept like a baby, and made a mental note to wash that shirt first thing tomorrow.

December 15, 9:20AM

"Waffles?" I said, holding the tray out to a sleepy-eyed Emma.

"Yes, but why are you in my room?"

"Might as well ask me why I'm in New York. I'm not. You slept on the couch last night."

"What?" She looked around. "Oh shit."

"Coffee is on too if you need it." I turned back around, letting my sister wake up. She'd somehow fallen asleep without a covering. When I woke up this morning I found her shivering and covered her with blankets. I also may have pulled up her pants after a minute -- maybe a little more than a minute -- of staring. I let that serrated edge of memory slip through my psyche like a falling knife, hoping it wouldn't catch anywhere it could do damage on the way down.

After a couple hours to ourselves, we both met back in the kitchen to talk about lunch, agreeing that we should make some soup. I was getting the stock and seasoning started, her, the meat and vegetables.

"You can actually move things around on the pan now without looking like a robot." I joked to Emma, who had been a notoriously poor cook in our household.

"Living alone teaches you to adapt pretty quickly. You know I've always liked food, I just used to have peons like you around to cook good food for me." She smiled a mischievous smile, and I laughed at the retort.

"Oof, you do know how to make me cook for you."

"I just do something wrong on purpose and let you correct me through example. It's a fool-proof strategy and a devious use of my charm."

"Devious indeed." I echoed.

As the soup came together over the next couple hours, we started to fall back into old patterns of speech. Time fell away, and people we used to be meshed with who we now were.

As I went to taste the soup as it simmered away, Emma and I brushed shoulders. I took a step back to let her to the stove and placed my free hand on her shoulder. I'm 6ft, so while I don't look exceptionally tall, when I was near Emma it was always obvious to myself and everyone else the massive difference in height we had. She flinched just slightly when my fingertips brushed her bare skin, exposed through her wearing a tank top.

I was once again aware of my sister's body so close to mine, and of how little fabric there was between us. I put the spoon to my lips. "Could maybe use a little more salt?"

Emma nodded, taking in her own spoonful. She may not have noticed it, but she was leaning into my palm a bit.

December 15, 1:23PM

Over our respective bowls of soup, Emma and I both read the news for the latest numbers, and I texted with Siobhan. She said she was almost done with her book, that she was going to be going from spa to spa from 2:00PM onwards, and that she was feeling a lot better than she had yesterday. I also received several photos of her in a bikini.

I typed down a reply to Siobhan and hit send when Emma said, "I think we need to finish that movie. What do you say?"

"Right now? Sure."

We took our bowls into the living room, once again setting up to watch this... Ballad of London or something. This time Emma curled up with me before we'd even started the film.

More verdant splendor was before us on screen. The hero succumbs to something dark and twisted within his own nature, all while his power grows. It was less sexy than a bit sobering. What the hell was I doing with Emma? Siobhan was someone I would never want to leave. Emma was my sister. I kept pushing for more than I needed and I should know that something is going to brea--

"How did you and Shiv actually meet?" Emma took my hand and interlaced her fingers with mine, still looking at the screen.

"She was auditing a course I was taking but kept missing the classes because they were so early, so she would ask to look at my notes." I grimaced. "She actually did a bit better than me on the mock exam. Didn't expect that a STEM major would be so jazzed over lectures on archival glue chemistry and pigment isolation."

"Really? That's cute, you're definitely both bookworms so that's a pretty great story about how you met." After a pause, Emma suddenly burst out laughing.

"What?"

"Sorry, I, this is stupid. I just was imagining how much more awkward this would have been if mom or dad were here." She said between snorts and giggles.

I was shocked. Not at the thought of them being at the front door to greet us alongside Emma, guaranteeing that every ensuing conversation that we had had since our arrival would have some extreme compounding awkwardness, but in fact I hadn't even considered that possibility until Emma said it.

"That is actually much worse, you're right." I said with complete sincerity, grimacing, making her laugh even harder. She started to calm down, and gathered herself back together, curling. Her hand was still with my own, mine cupping the back of hers, fingers still stitched.

We both went quiet after that, letting the film once again capture our attention. Violence, tragedy, defense of honor. I was drawn into the tense situation with a vigor I had not had up to this point. I could feel Emma's body tense alongside mine as well as the music swelled.

The movie ended in a sort of tragedy. A failed hero. A sobering vision.

We watched the credits play through, both of us with naught but our clothes between us, my hand entangled over her breast. We breathed in unison, and I could feel Emma tense against me. I wondered what had happened and looked back to the screen to see if anything had come up during the credits. But she wasn't looking at the screen. She was looking at the hard drive stuck in the computer, the device that would have this rip of the movie stored on it. Her hard drive. A hard drive that probably also had her porn on it, how else was she watching it last night? What software was she using to watch the movie? If it was the kind that had an autoplay feature, and she'd already played another video on this device, would her porn come up next?

I waited for her to move for it, to push my hand aside and rush for the drive, scrambling to explain her rush with some terrible on-the-spot excuse. But she didn't. She was just tense.

My eyes couldn't leave the screen. Name after name passed by, and I knew that there were but seconds. I wasn't breathing. Suddenly, all was black. A circle appeared on the center of a black screen, spinning once, twice, loading.

Time was slow. I was calm. I noticed Emma breathing far faster than usual, and that her grip against mine was almost gone.

There wasn't an intro or a watermark to the first video. My sister must have edited her pirated porn around just the blowjobs. We both sat frozen, seeing girls salivate and gag over cock, clearly enthusiastic about the entire process, but especially the result.

"So, I hate to ask this now, but are you still seeing only women?" I heard someone say in my own voice.

"I--" Her voice was hesitant, her skin redder than I'd ever seen it. "Yeah, I still only like girls."

"Cool. I get that."

"You get that?"

"No, I really don't."

"It's a kink. Yeah, I think sucking dick is hot." Her words had some ice to them now. "Does that make you happy?" Her words almost physically lashed out at me, her eyes still fixed on the screen. I could tell that she was feeling vulnerable, and I had been insensitive.

"Yes, it does." Who keeps saying things in my voice? Get a grip man, you don't say that to your sibling.

It was her turn to stop breathing.

She moved the hand that pressed against mine on her chest down her abdomen, leaving my palm to fend for itself on her breast. I squeezed without intending to do so, making her hand's movement stop for just a moment, until it snaked under her clothes and down her pants.

"Oh." She said, looking up at me. As she began to touch herself I could see her lips part in an open-mouthed gasp. Emma was pleasuring herself while I caressed her, while she lay upon my chest. This was so wrong.

My hands disagreed. I played with her areola, nipple still inverted, to great effect, getting a satisfying squirm out of her with every tweak and gentle press into her. My other hand rid myself of my belt and trousers, freeing my penis from a barrier that it had been fighting against since she had begun cuddling against me on the couch. Emma's eyes were immediately glued to it, but this did not stop her movements.

I took the initiative this time. I sat up, no longer stroking myself, and placed my hand alongside my sister's, making her eyes widen as she felt my rough skin against her fingers and labia. She leaned back to kiss my neck, and I leaned forward to do the same, still teasing her now-erect nipple.

For another few minutes, we stayed like this. I bit her neck to whispers of "gentle," and that she didn't want any hickeys. I hungered for those exact things, something to mark her, but I relented. We moved our mouths so close to one another, still feeling each other's breath on our lips, but not closing the gap to kiss. We hadn't done that before. Even after all this, that felt a step too far. She brought her hand, covered in her juices to her mouth, and held it up between us as a sort of barrier. Her tongue slowly lapped at her splayed hand, one fingertip making its way to my tongue. We each kissed and tongued at her hand, both of us with shut eyes. I pulled away from her, seeing her eyelids flutter at me as my fingers stopped their massage around her pussy and plunged inside of her.

"Take off your clothes." I ordered, and she did just that. Her shorts fell to the ground, and she heaved her shirt over her head. We went back to two years ago. Her body was the exact same as I had remembered it, just not covered in cum.

"No, keep moving," she moaned, as I realized that I had stopped fingering her to ogle her instead. "Or taste me."

That afterthought falling from her lips became my fuel. I let her body down, and slowly moved away from her, my eyes trailing along her breasts, abdomen. I was taking in everything. Emma's fingers tightened around my collar, and while at first I thought she may have changed her mind, I realized she was pulling my shirt over my head. Fair's fair.

I put my hands under her thighs. Lifting them up and towards me, sneaking a pillow under her ass to make it easier for me to access without breaking my neck. Emma gasped again, one hand twisting her bare nipple while the other ran itself through my hair. She was being a lot more forceful with her nipple than I had been. Noted.

I spread her legs with wonder, letting them fall on my shoulders. I kissed along her inner thigh, running my tongue across her in ways that I hoped made it plain I was teasing her. She oscillated between gasps and delighted squeals, which made me tease her even more.

"Do you eat Siobhan's cunt like this, Sig?" She said in a tone that almost made me think she was genuinely bored, but I could detect the challenge there. I moved in hard, loving every second of tasting her pussy.

A gasp turned to groans as Emma begged me for more. More tongue, more hands. My mouth was latched around her clit, being careful to not overstimulate her. I had reflexively put my index finger in Emma's mouth, pulling her cheek to the side, making her taste my precum and her pussy juice. I could tell that she could taste the difference between our fluids, and it turned me on to see a look of pure delight on her face.

"You like that, don't you?" She nodded, head movement limited by the grip I had on her mouth now.

"I can tell you like the taste of my cock. Where you do you want it?"

She froze. Her breathing became faster, and she went to form a word with her mouth but wasn't able to.

"Say it." I could see the change in her eyes. We had been playing up until now. But she was ready. Ordering her to speak her desires could liberate her from the guilt in having them.

"I want your cock in my mouth. I want to taste your cum and feel it on my lips." She barely whispered to me. She was looking back at the TV now, my hand leaving her mouth as she turned away.

I kissed her clit again to a satisfying response.

"Good girl." Her body started shivering at my words, and I refocused on her labia, letting her climax on my tongue. I stood up, letting my trousers fall entirely. Emma sat up, and her face wound up right below my cock, dripping with a renewed batch of precum.

She put both her hands to the sides.

"This -- was inside of me before," she said with amazement, feeling out my curve and lingering on the leaking head. "I remember it being so much, but--" I guess she'd really only been near the one, mine was a little bigger than the average but it wasn't exactly massive. I let the words soothe my ego anyways.

She stuck out her tongue, licking the underside of my cock, letting her tongue drift underneath my foreskin to the glans of my penis. She could tell that she was getting a reaction out of me, and I let her savor this. This was her fantasy, I would let her gain some confidence before I trampled all over it.

Her oral was awkward but adorable. I was already on the edge of climax, and Emma's fumbling made something I was usually not that enthusiastic about exceptionally erotic.

"To answer your question, yeah, that was how I go down on Siobhan." My sister's legs buckled slightly upon hearing that as she wrapped her lips over my cock, starting to let more of it between her tongue and roof of her mouth. "This is your first time sucking cock, right?" She nodded. "Then let me take control. Lie down, with the back of your neck resting on the armrest. Facing up."

She froze, but went to assume the position with a near-reverent grace for the pose I had described. She was waiting for this. She was ready for it.

I slapped her face with my cock, and her mouth once again opened wide to my knocking. My balls, thankfully pretty recently shaved, fell across my sister's forehead and her eyes as she tried to stuff my cock in her mouth.

"Have you been practicing this?" I cocked an eyebrow at her eagerness.

"I don't have a gag reflex," she said with all seriousness, eyes looking up at me, tongue on my cock. "Still need air, but I want you to use my throat."

I pushed into her mouth, my hands wrapped around her neck on either side, gently putting pressure on her throat as I felt my cock slide down it. I could see her touching herself vigorously, so I felt like I had a barometer of when I should be letting her breathe. Her tits jiggled as I fucked her throat. She kept letting out these grunts and moans through my fucking her, and when I could feel myself get close, I knew I needed to choose where to fire.

I pulled out of my sister's mouth, seeing her dewy and lusty eyes with a slight sense of confusion. Not sure why I hadn't warned her she was going to lose the dick in her mouth. She figured it out right away. My cock is curved a bit upwards, and the first thick rope of my cum shot far overhead. A milky line was drawn across her entire body, from right above her pussy to her eyebrow. This got a gasp, but she was ready for what came next. She pointed her tongue straight up, letting my load pulsate into it and slowly drip down into her throat. Our eyes were locked.

She closed her mouth. And looking at me with tender uncertainty, swallowed.

"Thank you, Sig." Something flexed inside my heart.

December 15, 7:17PM

"Hey, how do you feel about reheating that soup again? I'm a bit -- not wanting to make dinner" I caught myself from almost said "tired" as if I was ready to call attention to why we were both clearly exhausted, or the reason that we'd both needed to shower twice today.

"Yeah. I think there are some saltines, too, we're out of dinner rolls."

My sister sat resplendent, her long hair in a towel bun, sipping at her tea. She was so at ease.

We both ate our soup on the couch again. TV off, both facing each other from either end of the couch.

"So Siobhan is coming back tomorrow," Emma said. "And I don't want to fuck that up for you."

"Okay. Same."

"No. Not 'same,' Sig. You need to figure out what you want us to do here."

"What? Why me?"

"Come on, I saw you last night. I saw you jerk off to me in the reflection of the TV. I almost was ready to think it was a dream until I saw that you'd done laundry for a single shirt this morning."

"You saw that?" I dropped my spoon into my bowl with a clack, a bit mad at the thought of being spied like that. Well, caught spying.

"No," she smirked. "I can just tell when you're hiding something, and you just admitted to it."

"Fine, you got me, I have no plan. It's been two years and I left our-- I thought I left everything behind me. But seeing you here, being close to you? Finding out that you fucked my girlfriend?" I paused, wondering how much that was actually a factor. "Yeah I'm a bit all over the place. Sue me. You're the lesbian who just sucked her brother's cock."

"Okay, well, I fucked her first," Another line no sibling should say to another, "And I feel the exact same way that you do. I don't like men, but I've been thinking about your cum for two years. You still taste the same, I remembered it on my tongue. When I see those models swallow loads I imagine that it's your dick in their mouth, filling them up. I've let that kink build up for two years, and I didn't know that I wouldn't be able to hold myself back from you."

This stiffened me. We'd gone separate ways and had treated this event so differently. She had fixated on it, I left it behind only to grow no tolerance for her body's temptation. I wanted to hold her then. She looked like she regretted saying those last few words, her face growing pink again.

"I mean you're literally with someone right now. I'm a terrible sister, friend, and ex."

"I wanted to do everything that we just did. Don't apologize for it."

"But--"

"No. I said what I said. We can talk about it and draw boundaries but we can just start fresh."

"Okay. Did you guys fuck in the garage?"

"No." I reeled back a little, "What? Why is that your first thought when I said we should start fresh?"

"I could smell her on you yesterday. I was pretty sure I could smell your cum too."

"Oh. That was from the night before," I grimaced. "I thought you might not have noticed."

"Please. I literally dated her. Actually, I fucked both of you before either of you fucked each other."

"Can you shut the fuck up for a second?" I paused. "Sorry. I guess I'd been trying to not dwell on that time." I saw disappointment in her face and I knew I needed to be more upfront. "Not because it was bad, I thought that you might hate me because of it. I felt like I took advantage of you. I wasn't sure what to think, so I let the memory fade. Until yesterday."

"I couldn't hate you for that." She whispered. She looked up at me then, tenderness and affection in her eyes. "But we do need to figure out this whole business. No hard feelings, fine, but what are our ground rules? We're about to live with your girlfriend for a couple months, and I think it's a bad idea to have that thing inside me if you want to keep your relationship with her intact."

I sighed. "Okay, well you're the rules-lawer-UN person, how do we keep the peace?"

"UN. Climate. Secretariat. But fine. 1) no more touching unless it would be weird to not do so around other people 2) no mention of our previous sexual activities with one another 3) treat Shiv nice."

"Simple, hard to misinterpret. And if we break one of those rules?"

"We don't." I got a look from her.

I looked her in those eyes again. Eyes I had seen come to climax over and over now. Fuck.

We shook hands. A final breaking of rule 1 to commence this truce.

December 16, 8:30AM

Siobhan's lips pressed against mine hungrily before I had a chance to welcome her in. I was happy to see her back, and even more thankful that she was back so enthusiastically.

"I like your nails." I managed to get out, gasping with her as I caressed her waist and butt with my hands, pulling her into me.

"Quiet. I got waxed yesterday morning, and there's no way I'm letting you waste a single compliment on my nails. I want your mouth all over my cunt."

I stopped arguing, and let her lead me to my -- I guess our -- room. She took off every article of clothing with such casual grace I'd never seen from any other woman, throwing them over what little fixtures I had actually moved back in since we first arrived. Her bra on the lamp, panties on the dresser, coat and button-up white shirt on the floor. She sat on the bed, wearing nothing but her pencil skirt, beckoning me closer.

"You're ordering me around, huh?" I mused as I walked to her. "That's not wise of you."

She shivered at the implication of my tone. "I think that's fair. I have what you want, don't I?"

"I think we both have something the other wants." I crouched down. Her pussy was rounder, puffier than my sister's, with more tucked away labia. I need to stop comparing them. I was agape at seeing her skin this perfectly smooth. More exposed than I had ever seen her. I let myself go to work on her, tearing her apart with my tongue. I looked at her expression as I drunk her down, and saw how little she was in control of herself. I brought up the pace, pulling her nipples in rhythm as she began to gyrate against my jaw.

As I could feel her start to climax, I pulled back, letting the recoil of a failed orgasm ripple through her body. "No, no," she begged me, "I've been your good girl, I know that I deserve to cum."

As she opened her eyes, she looked down to see my cock at her entrance. I slapped her clit with the head to get the cry of pain and pleasure I loved to wring out of my girlfriend. She was the best fuck I had ever had, and responded to my dominant preferences with incredible enthusiasm. "Ask for it." I said. She smiled, closed her eyes tight, and shook her head in refusal. Brat. I slapped her pussy again, this time with an open palm instead of my cock.

She let out an, "Ah!" before beginning to wrap her legs around my torso, cracking open one eye to give me a slightly suggestive smirk.

"I said to ask for it." Her breathing stopped, her eyes now on the hand I had used to slap her.

"Fuck me, Sigurd." She smiled shyly. All I needed to hear.

Our lovemaking lasted a bit less than it usually did, but we were moving at a pretty fast pace. Maybe ten minutes in I was starting to get close, and I leaned in to Siobhan, kissing her neck and whispering sweet nothings into her dark hair covering her ear.

She wrapped her hands around my head, bringing me to her.

"Do you want to cum inside today?

"What?" We had talked about this, and I thought it was off the table. I kept thrusting, my cock getting harder.

"I might be ovulating right now. It's feeling like I'm ovulating now, but it might be a bit before. I'm not totally sure but my breasts feel swollen and I'm warmer than I should be. If you pump your seed into my womb I know I'll get pregnant."

"I--" Was at a loss. I knew that these were just sweet nothings, and that neither of us wanted a kid right now, especially now now. But these words carried some real significance. This was a kink that I hadn't expressed openly to her before. Had she found my porn stash? Either way I felt a renewed pounding in my balls. I yearned to empty into her, stuff her with my seed, and mark her as my own.

"You're saying if I cum now, you'll get pregnant?" I gasped out, refusing to slow down our fucking. She wasn't on birth control due to how insane the side effects were for her. She told me she felt bad about it, that I was never able to cum inside of her. I didn't see it that way. Fucking her raw, knowing the only thing between my sperm and her womb was me pulling out, was made all the more hotter knowing she was ready to carry my baby if I was even a second late.

"Almost a guarantee." She began to really pump away at my cock, managing to add a lot of power even from below. I felt weak. I looked at her face. She was loving this, but I couldn't make out her end goal. Is that really what she wanted? Or was she enjoying seeing me squirm?

"I'm going to come." I grabbed her face roughly, pulling her face to mine. "I could do it inside you. You would look so fucking hot pregnant, Shiobhan, maybe I should fill you up just so that I can drink from your fucking tits." She buckled, clearly not anticipating me turning this around on her. Looks like I wasn't the only one with this fantasy, too.

I felt her climax on my cock, her insides writing against me. It was too much, and I had just enough mental fortitude to take my cock out of her pussy and into her mouth before I came everywhere. I shook from the sensation of her tongue and the roof of her mouth as I face-fucked her. She cleaned me dutifully, almost bringing me back to a full erection with her tongue before she relented and swallowed it all down.

I collapsed beside her on my bed. Still a bit shaken.

"You always get a bit flustered when we talk about my cycle or protection. You hate condoms and you love cumming while your shaft is pressed between the lips of my cunt. That's why I said what I said." I was staring at the ceiling in awe, and glad she didn't find my porn stash. "Did you like it?"

"Siobhan, I fucking loved it."

We kissed then, our bodies writing over the mess of sheets we'd made. She was so special. I broke off our kiss to move my mouth closer to that perfect pussy of hers, but as I began to lower my head, she grabbed my hair with force.

"I didn't exactly rinse my mouth out. If one of your swimmers is in your saliva because I didn't--"

I cut her off. "Then you must be really really fucking fertile. I want to taste you, and I'm taking the risk." Her eyes widened. She loosened her grip on my hair, but still held me as I began my fun. Her moans were much louder than usual, and I wasn't sure that it was just the fact that this particular bout of cunnilingus had a minute but possible risk of pregnancy, or some other factor, like the novelty of being eaten out after being waxed.

I was lost between her legs, and only stopped when she pulled me up close to her face and whispered seriously: "Sigurd, there was a scratching noise in the room next door."

"What? From inside?"

"From whatever is on the other side of that wall."

"But that side is the laundry room and the -- fuck, the pantry." I didn't want to say mice or rats, as they were possibly the most effective ways I could have imagined to kill the mood, but I think I might have had it pretty clearly marked on my face that that was what I had in mind.

"Well wipe off your chin and take a look. I'll be right here."

"Thanks." I kissed Siobhan again.

December 16, 10:14AM

I walked naked into the pantry. The room was incomplete, having not had any drywall since it began being renovated back when I was in highschool, so most of the walls were really just sealed insulation. From what I could tell it had no signs of vermin. Bags of flour, rice, and other assorted dry goods appeared untouched, and the corners were all clean but for the cobwebs made by our faithful resident wolf spiders. I didn't see anything out of place.

I could, however, hear Siobhan's moans through the wall. I had always thought that my room was pretty soundproof growing up, and I tried to not think about what this meant for conquests I had brought home in my high school days. Had my parents, or Emma, heard noises like this coming from my walls in the past when they came in here to set up laundry or grab a can of beans?

I tried not to worry about that. I also stilled my breathing, letting the moans fill my waking thoughts. Something was still a bit wrong. Why was there a whiteboard in this room? Between the washer and dryer, a small white window was on the wall, a magnetic whiteboard that I thought belonged on the kitchen fridge.

I reached out to remove the board from the wall, and I realized that Siobhan's moans only got louder. There was a small gap in between the wooden support that held the whiteboard in place by a nail and the sealed insulation, and as I moved my eye to it, I got a view of my room I'd never known existed.

Siobhan lay on the bed, still touching herself, now with a piece of fabric that she had brought to her face. It was my underwear I'd worn yesterday, the one drenched in precum from Emma's teasings. I froze.

I shouldn't be watching this. But someone had been. I continued watching my girlfriend moan and writhe on the bed, seeing how she grasped at her own neck and breasts when she thought no one was watching. I was about to climax--somehow I'd been stroking myself without realizing I'd begun to do so, my cock still lubed from the pussy of the woman I was spying on.

It was then I realized I was no longer alone.

I suppressed a grunt as my completely naked sister walked towards me, got on her knees but from an inch away from the tip of my cock, and smiled at me, opening her mouth and letting her tongue fall out and away, as if reaching out. She didn't need to say it. 1) No touching. I could almost let myself break that rule, grab her hair and fuck her throat properly, but I contained myself. I looked through the peephole again, the sounds of moans coming from the other side making my heart flutter. I looked back down at Emma.

Seeing her like that felt so right. I imagined myself inside of her. Filling up my sister with cum, getting her pregnant with my seed. I was shocked at how much the thought of that thrilled me, and I once again needed to hold myself back. If I asked her to get up, to turn away from me, to let me enter her from behind as I made her watch Siobhan pleasure herself through the peephole, to take my cum inside her womb, would she do it? I saw nothing but love in those eyes.

I erupted over my sister. No aiming this time. Her face was an ecstatic canvas as I ruined her with my seed. Her trembling hands gathered it up from her face and brought it to her mouth, where she ate it down. She took a handful off of her neck and held it before her, looking at the pearly liquid as if she was trying to remember why she was holding it.

I could see her wet pussy dripping from where she knealt, a small pool forming on the floor between her legs. Palm still upright to cradle the seed she held, she went as if to touch herself, gently bringing the pool to her entrance.

I froze. That couldn't happen. Had she heard our talking during lovemaking? I could see my cock throbbing as blood returned to it, jumping with my heartbeat. I could see Emma's chest fluttering too as she stared right at my cock, drips of semen falling from her cupped hand and my cock. She could fuck herself with that hand now and not break one of our rules. Was that something she intended? Or was this something new that she was teasing me with since learning I got off on the thought of impregnation? Maybe she didn't hear us at all and I was reading into nothing.

Time started again when she brought her hands to her chest, letting my seed cover her. I heard just the faintest gasp from her as she pinched her inverted nipples with her jizz-stained fingers. I saw both of her nipples start to emerge from her areolas, hardening under the coating of semen she'd lathered it with. She caught herself then, and gave me a look. She tilted her head towards my room, where Siobhan's moans continued but were getting quieter. Whimpers of pleasure. A solo piece that needed some livening.

I went to the kitchen, leaving my sister in the nude on her knees, stained and shivering with sin. I was shirtless, with my renewed erection prominent, ready. I passed by the laundry room on return to Siobhan to see my sister perched, one leg up on the washer to get some height, looking into the room to spy on my girlfriend as she masturbated. I tried to remember which hand she had held my seed with, but I let that thought pass me by as I continued.

As I entered my room, I looked for where Emma was watching from. I felt like an idiot, there was clearly a gap between two panels just barely behind my dresser, and with enough height, there was a direct line of site to anything a voyeur would want to see.

Was this new? Had Emma ever spied on me, alone, years before?

"You took too long, babe." Siobhan half-said, half moaned as she roused from the covers. I could see that she had thrown the underwear I had been wearing yesterday back into the hamper. Had I not known that she was using it, I probably would not have noticed that it was out of place among the discarded clothing. I kept the door to the room just slightly ajar, but could honestly not tell why I did so.

"No sign of rats." I kissed her forehead, handing her a glass as she sat up. We both hydrated ourselves, hunger in each other's eyes as we could see an end to this intermission.

We fucked for I don't know how long. She teased me again about finishing inside of her, how she would be swollen with child if I just gave her my cum. I was a bit more aggressive than I usually got with her, and biting and hickeys was my way of fighting back against her teasing. Marking her as mine and reminding her that she was under my power. She got on top of me, letting me see those beautiful tits bounce as I drilled into her.

"I know that you still want to cum in me."

"I do." I could only reply with full earnestness to this woman

"You still can. I really mean it. Just not in my cunt, baby."

I was confused. "I was going to cum in your mouth again, are we still talking dirty right now?"

She kissed me, and pulled her snatch off of my cock. She stayed there for a second.

"I said I wouldn't do this to you when we started dating," She grabbed my cock with a force I wasn't expecting from her small hands. "But I want to see your face as you empty your balls into me, and I've been playing with my ass since I got a hotel room."

"Oh my g--" I lost my ability to speak as my cock plunged into Siobhan's ass, her butt slamming down on my lap with a slap. She also clearly was taking a moment to adjust, mentally if not physically.

I started moving before I could stop myself. I wanted to let her have some time to recover, to let her drink in the pain and pleasure of both of our first tastes of anal sex. But I could not. I sat up, using my hands to pry her own away from her red, shy face as I saw a dozen feelings racing across it.

She was gritting her teeth in pain, but my kisses loosened up her jaw and we began properly making out. Her tongue was hungry, and as I began to increase my pace, she began to cry in between her gasps and moans. I was entranced by this beautiful creature who took the pain that I gave out with the same reverence as the pleasure. I licked her tears away and turned us over into a missionary position. She gazed at me then, sweat on every inch of her body, and beckoned me back to her mouth.

She began to touch herself, and gave me a bratty, angry look when I took both her wrists and pulled them above her head.

"Remember, I still get to choose who comes when." Siobhan's anger dissolved into a pool of subby obedience like sugar in hot water. "Come with your ass, or not at all." Her eyes widened at the order.

"Okay baby." She looked at me again with a renewed innocence. "But I really want to come. I'll be good. Choke me, pull on my nipples. I can still feel it coming, and I'm so close. Please let me come."

I wanted to oblige her. I still pinned her wrists above her head, but with just one hand now. The other was wrapped around her throat, just pressed hard enough to restrict the blood flow to the brain and not enough to damage her windpipe. She clenched her teeth, face getting red, lips in a mad hungry snarl. Her ass tightened around me and I was amazed that I could still pump away at all.

"Put a child in me, Sig." I almost didn't recognize the word in Siobhan's mouth. I was already solely focused on assfucking, but now with a renewed vigor. "Let it all out inside of me. Mark me as yours, forever. I know this is what you've always wanted. Take it."

It was. Sig? That felt wrong to hear from her. A good kind of wrong. I saw back to two years ago. Back on the couch. When someone was calling me Sig and begging for me to come inside of them. I was fucking Emma's ass then on the bed. No, fucking Emma's pussy raw, my own sister squirming underneath me, begging. That wasn't what was happening now, but it all felt so real. I felt like I was losing a grip on reality in Siobhan's ass.

I slammed myself again into Siobhan, interrupting her breathing with that force alone. I could feel her cum then, a warm spurt shot from her pussy all over my cock and our respective abdomens. I didn't hold back as I felt her squirt all over us. I came in her asshole with a glory I had never felt before, a relief to finally release and a satisfaction that it was inside of her. I forgot who I was fucking, and where, and when I opened my eyes, I saw love on Siobhan's face, a woman I'd just filled to the brim. I felt so undeserving of that love.

"You have to promise to do that to me again."

December 16, 12:32PM

Lunch was surprisingly uneventful. Frozen meals were a staple of our household. Our parents were proudly cheap even with their incredible salaries, and made an effort to make as many meals as could possibly fit in the freezer and use them when appropriate so that their schedules wouldn't make family dinners impossible.

I don't remember what we talked about. I think mostly about Emma's job, but I couldn't tell you for sure. We gathered around the couch to watch another movie, this time an action film that I again didn't pay any attention to, instead letting my thoughts turn inward.

I knew now that I loved these two women, one of which in a way that I knew that I shouldn't. As this revelation struck, and my anxiety over cheating on my girlfriend with my sister increased, I tried to steady myself mentally. I focused on breathing evenly, letting my surroundings disappear and not focusing on my senses. Even with Siobhan pressed against me on the couch, I could take leave of that sensation, sound, letting my vision unfocus. But I couldn't let go of something. I could still smell Siobhan. Her sweat, her juices, my cum that was still in her asshole. She had to have known that this drove me wild. She was a clean freak in almost every way, but she often didn't clean off my cum when I got it on her skin. She would massage it in sometimes, mixing it with her own fluids to cover a swath of her gorgeous slender form. She had been doing that for me, to turn me on this whole time. Back at the old apartment she would be painting in her nook, appearing chaste and fully-clothed to the eye, but I would nevertheless be immediately drawn to her by the scent of our love on her person. I hadn't told her that either; she must have figured it out by herself. I was either a lot more oblivious to how my lust displayed outwardly, or this woman was far more observant that I'd imagined. I began to wonder how well this woman knew me.

After the movie, we finally unloaded the U-Haul, and I was filled with a sense of relief that we'd sold most of our furniture before the move back home. I took off from my parent's house to return the truck before they closed, leaving Siobhan and Emma behind. It was a 30-minute round trip, but I was enjoying my time alone more than I expected and stopped into a coffee shop near the rental place before taking a cab back. I finally took my mask off once the waitress delivered my order, delighted to feel kind of normal again in a real cafe with almost no one in it.

I had almost lost a copy of the collection of poetry I'd brought with me. It had been wedged behind the seat of the truck for most of the long drive homewards, thankfully returned to me by the attendant as I was about to leave. Happy to have it now, I turned the pages, drinking in the words alongside my beverage, silently feeling the verses out on my tongue. I had always had my place in coffee shops, and I was able to relax by losing myself in the words found in my book.

December 16, 3:46PM

I came home to laughter in the kitchen. Realizing that neither woman I'd been sleeping with had heard me come in, I tried to listen in to what they were talking about. Siobhan was recounting a story that she had once told me, about a professor that she had in her final year as an undergraduate. Emma's giggles as the story escalated were like music to me, and I was starting to be able to see them as a potential couple for the first time. I wasn't sure how I felt about knowing that. I'd only ever seen the submissive side of my sister, but Siobhan was a brat to the core when it came to sex, and she certainly knew it when we first started hooking up. Maybe they didn't engage in much kink at all 2 years ago, but that didn't feel quite right. I tried to imagine their sexualities opposing one another, how they would interact in the bedroom. I imagined them both pleasuring the other, taking turns teasing and nipping at the other's flesh. Back in reality, their voices then turned a bit quieter, and I couldn't make out exactly what Siobhan was saying in a very firm tone to Emma.

Done with eavesdropping, I slammed the door then, making it seem as though I'd just arrived. I could smell food cooking as I rounded the corner into the kitchen. They both turned to me, Siobhan sitting on the countertop and Emma at the stove, tending to some simmering julienned onions that were halfway browned.

"Look who decided to show up." Siobhan teased, going in for a kiss.

"I stopped at that cafe beside the rental place before I came back. Sorry to keep you waiting."

"No trouble, we had some more time to catch up." Emma smiled at me.

Man, that was worrying.

December 16, 9:20PM

Most of that evening we spent both together and apart. Each of us curled reading on a chair or the couch, cleaning or making tea while watching a clip from a youtuber who was also clearly losing their grip on reality as well amidst the spike in cases.

Siobhan fell asleep first, dropping the copy of her book unceremoniously on her face as she passed out and her thumbs lost strength. Amazed she didn't wake up from that, I picked her up and brought her to our bed, laying her down.

Still restless, I came back into the kitchen.

Emma was waiting there.

"Hey."

"Hey."

We both shuffled a bit, uncertain what to say.

"That was super hot. I didn't know she would let you assfuck her."

Okay. I guess I was the only one who hadn't known what to say after all.

"And I didn't know that I was being spied on." She winced, sensing the real feeling of violation I'd been harboring, even if I had loved it so much that it actually scared me. I enjoyed showing off to my sister. Letting her see what I could do to a woman. "Is that the first time you've done that?"

"Yeah."

"And you just happened to find this peephole?"

"No." As she saw a look of confusion run across my face, she gave in. "One of my girlfriends did. Debbie."

"Debbie?" I said incredulously. "Who the fuck is Debbie?" This got a big grin from Emma.

"Right? She and I dated for like two weeks in high school. She said she was bi, but when I caught her spying on you changing, she came clean about how she wanted to get to know you better. She was the one who pried out whatever filler there is between those boards that make up your wall and covered the other side with a whiteboard she took from the kitchen." My jaw dropped. "Yeah, and I never told you about it because it was embarrassing. I gave her a massive talking to about stalking and how I'd kick her ass if she tried to come back into our lives. And you moved out pretty shortly afterwards, so I couldn't have used it before." She sheepishly looked to the side. I was unsure if that last part was true. I didn't remember Debbie, but Emma seeing someone right before I moved out did actually sound familiar.

This was a lot. I opted to ignore that whole line of implications. I let out a sigh.

"It was super hot." I conceded. "But you really were bending the rules. What happened to those?"

"She found me out, I wasn't trying to make a noise. I scraped the wall a bit when I went to move down and I heard her call attention to it. When I saw you peering at her, when I heard her moaning, I knew that I wanted to join in, even if it was limited." I went to speak, but she cut me off, "I followed the rules. If you want to add a new one that says I'm not allowed to watch you fuck your girlfriend through a hole in the wall or let you come on me, then you can speak now."

A few minutes passed.

Maybe a bit more.

I stood in the kitchen alone.

December 17, 9:21AM

"Okay, this time, it is actually your room that I'm in." I woke up to see Emma sitting at the foot of my bed. Naked, her blonde hair did a poor job at covering up her skin from my gaze. I was still half-asleep and coming to grips that this was, in fact, reality, and currently happening right before me. Her nipples, only a slightly darker pink than her pale skin, were already erect. Her breasts were so small that I couldn't help but want to put my whole mouth on them, lash at her with my tongue. I realized that my morning wood was quite prominent on the thin sheet that covered me, the room itself being quite warm.

"You washed since you fucked Shiv's asshole. I can tell." She winked at me.

"Emma, what are you--what if Shiv comes in--" she held out a hand to my mouth, not touching but hovering in my face, shutting me up.

"Shiv is working out. She borrowed my car and left to go to the YMCA 5 minutes ago. Does she still never work out for less than an hour at a time?"

"Yes, but--"

"Then we'll be alone for this." I was confused until Emma coyly moved closer to me on all fours on the bed, feet first, still on the covers, letting me get a close look at her pussy and asshole while still keeping us from touching. "I want you to tell me that my ass is pretty too. And that if I weren't your sister, that you'd fuck it."

I stared at her then. She had a gorgeous ass. It was so perfectly round and plump for her slight figure, it was magnificent to behold. I held her ass when I pistoned her before, letting my fingers sink into her soft skin so that I could fuck her more intensely. I wanted to do the same, now, but I would not let myself break.

"Your ass is pretty, and I might still fuck it." She squealed a little, caressing my cock through the cover and my shorts. "All I'd need to do is add a new rule, right? So long as it's just your asshole, I can touch you."

I could not believe that I was saying this.

"I can feel you getting harder, Sig." I saw her asshole twitch as she said it, a shiver running down her spine, making her curves ripple in response to her arousal.

"That's not a no."

"I mean I would hate to leave this thing the way that it is. Give you--" She paused. "Blue balls."

"I know this is a weird time to correct you, but blue balls aren't actually a guarantee and usually aren't very painful. Some guys just lie to guilt girls into having sex."

"Wooow," She looked back at me, rolling her eyes. "I'm so glad that my brother is making sure that I'm cautious of any men who might want to take advantage of me."

"It does, uh, kind of suck to go half-way, though. Here, lay beside me." She rolled over, her face landing down on the pillow, plump ass facing upwards.

"Where are you off to?" Emma mused, seeing that I had left the bed to walk over to my boxes.

"I'm going to make sure that you don't move around too much." I lifted the loose straps from where I had left them yesterday, the black ribbons that we had used to fasten the more awkward pieces of furniture within the truck.

Emma tensed when she saw what I meant, and sat up against the wall, her breasts now once again facing me. She caught me staring and looked away, but lifted her hand to brush on her nipple all the same. I let my undershorts fall to the ground.

Holding one of the straps like a garotte, I approached my naked sister with an urgency that surprised even me. I ran the taut strap under her left ankle and wrapped it without touching her flesh directly.

"Your wrist?"

Looking at the strap with an expression of desire, she held her left hand out, and I once again wrapped the strap to restrain her. I pulled, bringing her limbs together, and tied them off. She gasped when I took the slack from the line. I got to work on the other side, both her wrists now connected to her ankles. I relished this level of control over this sweet girl who would let me take all of her for myself if I so desired.

"How did you seduce Siobhan?"

She wasn't expecting that question. "I asked her out after we voted on the budget for the forestry--"

"No, how did you treat her in bed? You've seen her be a sub for me. And I'm literally tying you up now. I was wondering how you fucked her."

Emma blushed. "Um. She was always subby for me too. She liked it when I slapped her some, and I had a strapon that would use when she needed a fucking. I used to make her--" She closed her eyes and turned her head, still on her back, not able to cover her face no matter what she wanted.

I threw the sheet over her, grabbing her body through it so as to not break rule #1. Her curves were refracted through the thin white sheet, making her trussed up body look like it was made of marble, only her head and tied up ankles exposed to the air. She looked down. My cock was resting between her legs, perfectly cradled between her labia. I pressed into her, feeling her juices soaking through the thin cotton covering that kept me from her entrance

"Used to make her what?"

"I had her use a toy on me sometimes too." That looked like it took a lot out of her. I was endlessly curious about the exact nature of the toy and its uses, but I also had my sister's asshole right in front of me almost begging for me to fuck it, so I had my priorities.

"Really?" I said, now lining up my glans with her asshole, sheet still between us.

"Yes. Oh my god you're really going to do it."

"I'm not going to miss out on enjoying what's mine. Isn't that right?"

"Yes, do it. Please."

I lifted up the sheet. The bottom hem fell over Emma's wet entrance when I moved it up, rapidly absorbing her fluids. Her asshole was perfect. I brought the tip to it, looking into her eyes for any sign of hesitation. Was this too far? I instinctively upped the ante when she teased me, feeling the need to retake control over our sexual dynamic and make it clear that she satisfied my urges. But I worried that my next step might be the one where I went past her boundary. One where I broke a relationship beyond repair.

I entered her. Her mouth formed a scream that she did not let out, and I saw that she was now digging her nails into her ankles. She had clearly prepared for this, I could smell a lightly vanilla-scented lube mixing in with my precum coating my cock as I completed my first stroke. Even though she was still clearly adjusting, she locked her fierce and passionate eyes with mine. A reminder that she clearly wanted this as much as I did. I should not have bothered worrying about going too far for her sake.

I began deeper strokes, digging into her with every thrust. I massaged her tits through the cloth, and her voiceless cries turned to moans and ecstatic gasps. She shook when I halted my caressing of her breasts and pinched her nipples.

She was on the edge. It wouldn't take much. I leaned down to her face, my mouth not more than an inch from hers. She mumbled something to me, but either she was having difficulty enunciating or I was having trouble hearing her.

"Look at my little slut," I said, "You want what you're not supposed to have. Are you thankful that I have my cock buried inside of you instead of Siobhan?"

The look on her face was one of arousal and embarrassment. A little bit of fear. She nodded. We hadn't done much dirty talk and I could tell she was excited but unsure what to expect from me.

I grabbed a handful of her hair, making sure that I did not do so while touching her skin, and pinned her head down with it. Her lips again coiled in a beautiful expression, and I had to use every ounce of restraint to not kiss her then. I spat in her mouth, catching her off-guard but immediately getting her attention. She played with my saliva on her tongue, rolling it around, showing it off to me.

"If I touched you now, would you want me to be gentle, or would you want me to slap you around like we do Siobhan?"

"Both, Sig." She said in a near-whisper. "I want you to do everything to me."

"You want me to cum inside you."

"Yes. Fuck yes, Sig, I want it inside of me."

"You want your own brother to come inside you." She looked at me, a renaissance masterpiece of innocence and lust occupying the same form, querying: 'would that make me so bad?' Her pussy had far more than soaked through the sheet that separated us, and I could feel the warm drips of her wetness wrap around my shaft as I continued to plow her ass. God she was intoxicating. I was completely bent forward now, my hands on the straps around her angles to get any sort of purchase as I lost control of my lower half. I could feel Emma's breath on my ear and I buried my face beside hers on the pillow.

She whispered to me then, a voice so sweet and quiet I almost didn't hear it, "Put a baby in me, Sig."

My body wanted to knock up my sister. I wanted to see her pussy dripping with my cum, tummy swollen from the fruits of our lovemaking, her tiny breasts swollen.

"I love you." Words not spoken as a sibling, but as a lover, I felt myself erupt inside of her.

She squirmed as I finished in her, not able to move due to her being tied up so tightly, I could hear her whimper "thank you Sig," over and over.

We lay there for just a couple minutes before I got off of her, letting my still-firm cock slide out.

She was a mess of sweat, eyes still closed, expression angelic. She was a source of warmth and brightness to my eyes. I untied her, and she stirred, rolling onto her side, hands pressing between her legs, holding in my fluids. I sat on the side of the bed, still entranced with her even if my body faced away.

Even though I was spent, I felt the need to tease her again. To tell her to clean up my cock with her mouth, or make her show herself off to me. I hesitated, contemplating my feelings and where we could go from here. We'd made a slap-dash amendment to our rules based on mutual lustfulness. How long would it be until one of us decided that this wasn't enough? Was Emma just trying to match how far I'd go with my girlfriend? And the talk about putting a baby in her--

I imagined never biting Emma's lips again, never tasting her, never feeling her skin against mine. I thought of how every time I--

"Go take a shower." Emma righted herself to sit beside me. "I'm going to change these sheets. They're already pretty musty from your and Shiv's escapades yesterday, so it wouldn't be weird for you to put them to the wash."

"I--" Glad to be pulled from my thoughts and relieved that at least one of us seemed to have a plan in all of this, despite the hard-iron truth that my sister had just told me to go cover up our lovemaking so that my girlfriend didn't catch us. "Thank you, Emma."

She smiled at me, hand almost moving to my arm before she stopped herself. "I'll jump in the shower by my room once I have the sheets in the wash. I'm not letting the cum out though. You'll have to go through today knowing that I'm full of you."

December 17, 11:22AM

I heard the garage door close as I entered the kitchen, freshly showered and in jeans and a white tee. I could still hear the other shower running.

I sometimes fell into spirals of lust with my partners. We'd take advantage of days off to do almost nothing but screw and eat, letting our senses of time become clouded with attraction in a fog of sex. I felt this happening to me now, too, and I was fruitlessly trying to stop it.

"Hey handsome," Siobhan rounded the corner in layers of gym clothes, hair wet presumably from a shower after her workout. She pounced at me as I was reaching for the fridge door, wrapping both her arms around my neck and falling into me, her breasts pressing against my chest, still identifiable through the several layers separating us. Her upper right thigh, covered in but a soft athletic fabric, pressed between my legs.

"What is this?" She twisted her leg, causing her thigh to rub back and forth against my rapidly-growing erection. "Is this because of me? If you ask nicely I might help you take care of it. It really didn't take much for you to start thinking about my body, did it?"

If there was one thing that Siobhan loved, it was knowing that merely her presence could get me hard. A game she played often was to interrupt me when she wanted attention by simply sitting nearby when I was reading, playing a game, or working, and seeing how little effort it took to arouse me, shattering my focus and turning all my attention to her. When I would purposefully ignore these efforts, she tried to tease me, goad me into punishing her for trying to take the lead.

"You seem to still have a lot of energy, are you sure that you're getting in a real workout?" I grabbed her butt with both hands, fondling the cheeks and lifting her slightly, so she had to be on her tip-toes.

"Well thanks to someone, I'm already plenty sore." She bit my ear as she whispered to me, grinning.

"Hm. I don't know," I put my hands down the back of her pants, sneaking my fingertips under the spandex-like undergarment that she wore when exercising. "This all feels pretty tight, still. You might be sore but that's because you haven't been stretching."

She gasped as I pulled her cheeks apart, letting my fingers dig into the soft flesh around her asshole. She bit my neck and moaned as I played with her. She was briefly confused when I started to crouch down, but grabbed a handful of my hair and bit her own lip when she felt me pulling down her pants, exposing her ass as we both stood in the kitchen.

"Sigurd, what if she--"

"Shower." I responded, marking kisses from her abdomen to her hip. On an impulse, I bit her ass, causing her to shriek in surprise.

"You jackass, I can't believe you--" I slapped her ass on the same spot I'd just bit her, eliciting a sharp gasp and a fluttering exhale. I could never resist pushing back against her teasing, and I liked being able to tell when she wanted me to punish her.

I stood back up to see her eyes closed, teeth pinching her lower lip as she felt up her shirt. Sensing I was close to her, she opened her eyes with a bold curiosity and brought me in once more, kissing my neck again, moving one of her hands to my belt.

Emma silently rounded the corner. The shower was still running. Bereft of clothing, she leaned against the doorway, smirking at the show that her brother and her ex were putting on for all else to see.

Oblivious to our voyeur, Siobhan began to chew and suck on the same place on my neck. She was intending to give me a hickey. I was too horny to really register that, and my cock had recently been freed by her hand, so instead of telling her to stop, I helped her kick off what little clothes remained around her legs and removed her hoodie, leaving her clothed in but a sports bra and her socks.

My cock pressed between us, and I couldn't wait any longer, even with Emma in the room. We both moved in a beautiful synchronicity, her legs wrapped around me as I lifted her, both hands cradling her ass. Neither of us breathed as we lined ourselves up. I let her slide down my cock, every inch of her pussy a wave of pleasure.

She bit down harder on my neck before coming back to me to kiss me. Our motions were fluid, and I soon was not able to tell how long we'd been coupled like this, with one moment blurring into the next. She was trying to be as quiet as possible but that soon clearly became a significant difficulty for her, moaning louder and louder and digging her nails into my skin.

Emma still stood there, only watching, but now with an expression of awe instead of sly knowing. Her gaze on mine. Her form. I couldn't believe that I was letting her just stand there while I fucked the woman I loved. One of the women I loved. This was all so wrong.

Siobhan was whimpering with sounds of ecstasy, mumbling an unintelligible lover's mantra. I thought I could hear her saying "oh god Sig, oh my god," under her breath. I felt an orgasm ripple through and she almost let go of my neck.

"I'm going to come." I said, half to the woman I was inside, half to my sister.

"Not in my ass this time, I meant it when I said that I was sore." Siobhan just barely gasped out. I wasn't going to just fuck her ass uninvited, however fun that might be, and I think she knew that, but she had a music to her words that told me she was teasing me. "Where are you going to come?"

Emma wasn't in the doorway anymore. Siobhan's moans grew louder as I increased my pace, eventually leaving her warm insides to stroke myself between her pussy lips and her cheeks, where I began to jet cum outwards, across the kitchen. Not just the kitchen. I shouldn't have been surprised. I could spy over Siobhan's shoulder that Emma had moved from the entranceway and was now lying on the ground, awaiting exactly this moment. Waiting for me to cover her.

My lips met with Siobhan in a hungry panic that she would turn around to see the debauchery. With my eyes shut and face melding with my girlfriend's, I had to imagine my sister getting drenched as each white geyser billowed on top of her supple flesh from my cock. Siobhan's hands were cupped around my visage as the last of it left my body, both of us still upright but in an incredible stupor of bliss.

Still holding her up by her ass, I felt what I thought might be a tongue run underneath the length of my cock, ending at my urethra with a flick. Emma cleaning up whatever might still be on my shaft. Breaking one of the rules that we said we wouldn't break anymore.

If Siobhan felt anything out of the ordinary I couldn't tell. She loosened her legs from around my torso, tongue still down my throat as she set her feet down onto the hardwood floor. I drew her into me and slapped her ass, making her let out another moan. Emma was nowhere to be seen, Siobhan and I alone in the kitchen. We both tilted our head at the sound of the far shower turning off.

"I want you to eat my cunt. I've been good. We're going to your room." Unabashed by her present nudity she walked past me and down the hall. I mopped up the cum on the floor with a dishrag that I mentally noted to replace as soon as possible, gathered up our clothes, and chased after her.

December 17, 4:31PM

A mixed hour or so of cunnilingus, cuddling, and kissing brought Siobhan back down from her foggy submissive state. She recovered faster than I did, as I awoke to an empty bed, having fallen asleep without intending it.

Looking at the time and hearing no ambient sound in the house, I put on some fresh clothing and wandered out. I grabbed a glass of water from the kitchen as I moved through the house, looking to see if there was anyone around. No one in the living room either. I saw that Emma's door was ajar, and lightly tapped on it before letting myself in.

There wasn't anything to see, really. She had brought a lot of belongings, but few of them were unpacked. I heard the front door open and I quietly retreated back to a common area, making sure the door looked like it hadn't been moved.

All three of us made it to the kitchen at the same time, both women still dressed for the snowy weather outside and carrying groceries.

"Look who's finally awake." Emma snorted.

"I know you hate the bottled stuff but they didn't sell flats of diet dr. pepper at the market we went to." Siobhan said, ignoring Emma's snide comment and giving me a peck on the cheek.

"Aaand I got your favorite snack." Emma held out a giant bag of Funyuns.

"That is your favorite snack."

"It is? Oh, what a shame, I will need to eat them all by myself."

"And in the world of actual meals," Siobhan said, lathering her hands with sanitizer, irritated at the interruption. "We're having my scallop risotto for dinner."

I inadvertently nodded at this news, this was an exceptional development to the day. All three of us noticed at the same time that Emma and I were both making the exact same movements in response to Siobhan's words. I've always asked her to cook this meal when I thought I could get away with it due to how fucking choice it was. I didn't even think I liked rice until she first cooked it for me -- honest to god. But both Emma and I had been served this dish by our girlfriend before, it seemed. Siobhan turned a little red at this. We all started unpacking the groceries in silence.

The awkwardness thankfully dissipated fairly quickly, and we all went about our own little jobs in the kitchen, chatting mundanities and joking with each other.

"Can you believe this?" Siobhan held out the receipt to me, tapping it with emphasis to highlight the gravity of what was written there.

I grimaced. "I-- really wish that I couldn't." Neither one of us had to say the words "supply chain" out loud, but I was feeling okay about not needing to worry about rent for a bit. Less psyched about the no job thing, though.

Dinner was phenomenal. Food has always been a venue to my heart, but Siobhan's cooking kicked down the damn doors. Not one plate held a spare grain as we finished our meal, two bottles of white emptied between the three of us. Each of us were in a cozy haze, enjoying the buzz of the wine as we talked about current events and other interests.

Our conversation moved to the living room, and bottle #3 was opened.

The night wound down pretty shortly after that. Siobhan reached an inflection point in her cups and ended up curling up on top of me under a blanket as we were both on the couch.

Emma put on a movie. This one was a tale about knights. Bargains. Temptation. Paying recompense for slights, even at great expense. What it means to be a man.

"I didn't get to see this in theaters. The score is amazing."

"I managed to. It was worth it, but mom and dad have a giant fucking TV and this is blu-ray. You aren't missing too much." Did Emma's UN friends know how big of a movie buff she was?

Siobhan stirred. I realized that she had been dozing off. She looked up at me and made a move for my lips. I didn't pull back out of habit, but I was suddenly hyperaware of my sister's presence just a few feet from me. I wasn't sure if Siobhan knew, or if she was so groggy that she had forgotten what we were on the couch to do and whom we were with.

Regardless, she was certainly awake now. Her kissing was intense, and she pressed against me with a fierce and breathy fervor that made my heart race. I matched her intensity with some hesitation, unsure of what would happen next. She then stopped, looked me in the eyes, and gave me a quick peck before getting off of the couch.

"Sorry about the PDA, Emma," Siobhan said sleepily. "I thought I was back home."

Emma smiled at this nonchalantly, but I saw that she was pinching the seams of the leather chair she was sitting on with her fingernails and let out a breath the moment Siobhan looked away. Seems like we were all excited by Siobhan's performance.

We bid each other goodnight and I shepherded my tipsy lover back to bed.

"Today was nice, Sigurd." She disrobed, dropping her black jeans and linen white button-up to the ground. "Sig." She kissed me on the nose, giggling, and fell onto the bed. I saw that she hadn't been wearing any undergarments. I stripped down in kind, turning off the light and joining her under the covers. We made out a little more, and when Siobhan began to doze off, I felt myself joining her.

December 18, 12:14PM

We all took our time getting up, each of us going about our regular routine except with the added intention of clearing up our respective hangovers. We snacked on cinnamon buns that the girls bought the day before, reheating them in the oven, and enjoyed some tea instead of coffee.

Once we'd cleaned up, we discussed what the day would hold. I'd be holding down the fort, and the girls would be off doing some Christmas shopping.

I did some writing and emailing with my thesis advisor, sending some drafts I'd wanted to review more thoroughly before submitting, but realized that I was getting scarily close to the 3PM deadline we'd agreed to in the weeks past. I wasn't expected to do much and I was ahead of my studies, but I felt guilty for spending none of my time in the past two days doing my work.

As if beckoned by that realization, Siobhan rounded the corner into our room. I hadn't noticed the sound of the front door.

"Hey." She smiled as she came up from behind me, wrapping her arms over my shoulders from behind, bringing her forearms to my neck.

"Hey. How was shopping?" I looked at the time. I'd been working for more than an hour longer than I thought I had been.

"Fruitful." Cryptic.

I turned around. I took her in again. She was wearing a crushed velvet black dress that I didn't recognize. One with a leg slit and a low-cut bust that made her petite breasts especially pert. I couldn't believe that I didn't notice it when she came in -- this was exactly the type of clothing I loved to see on her but didn't pester her to wear for me. I thought her streetwear and alt aesthetic really suited her, but I'd never seen a better case for a dress on a woman.

"I've never seen a better case for women to wear dresses." Well, that one slipped out.

She grinned and planted a kiss on my cheeks.

"O breathe a word or two of fire," She whispered into my ear.

"Smile, as if those words should burn me," I whispered back completely by habit and in utter bewilderment that she would quote one of my favorite poems, one that even I had to concede was pretty corny.

"I like that you like my dress."

"I really do. Is it new?"

"You know that it is. I would have worn this for you already if I had it, I know you find this sort of thing irresistible."

"I find you irresistible no matter what. That said, I do appreciate a few of the advantages given by such a garment." Still seated but now facing her, my face below her bust, I reached through the leg slit to get a handful of her ass beneath the fabric, the other gripping her flank.

"Will you answer me a question, Sigurd?"

I held her close, not caressing any longer.

"Do you love me?"

"Yes, I do."

"Are you certain?"

"Yes." I was telling the truth.

"Good. Because I love you more than life. I think I want to spend the rest of my life with you."

"I love you, Siobhan. I want the same."

She took my hand and directed me up. She pushed me towards the bed and I sat down on the edge, seeing her look at me with an especially appraising eye, arms crossed.

"What?"

"I'm now waiting for compliments. Or do I only get the one?"

"You look as beautiful as the day I first met you. You mean the world to me and I don't know what I'd do without you. I love you Siobhan, and there isn't so much as a square inch of you where that doesn't hold true." I took her hand and began kissing the back of it, slowly drawing her closer to the bed by reeling in her arm to my lips. She straddled my lap, only able to do so thanks to the slip in the side of the dress, and our lips met once again. I didn't want to take off her dress quite yet, but I did want to see some skin.

"Mmm," Siobhan moaned as I massaged her breasts, plucking them from the soft cups of the dress. "I want to go on a real date with you in this, so don't get it dirty." She squealed a little as I pinched one of her nipples.

"I won't. I'll be gentle with it." I unhooked the back of her dress and unzipped her. She was grinding against me now, and I yearned to take off all my clothes immediately so I could actually feel her properly. But I didn't want to rush anything. This felt important.

She stood up and beckoned my aid in pulling the dress over her head. She took off my shirt and unbuckled my belt, leaving both of us wearing but a single undergarment.

Her panties looked new too. Very expensive, actually, I wondered if they were made of sil-- I was pushed back onto the bed again, this time a bit more forcefully. Straddling me once more, Siobhan moved up my body, positioning her pussy over my face. She didn't need to say a word. I grabbed both of her hips and pulled her towards me, pushing her underwear to the side, darting my tongue in patterns that I knew would get a response from her trembling form.

In a sense we were just going through the motions, leading up to sex in familiar increments. But something did feel a bit more erotic, more powerful than before.

We were soon in missionary, and I was fucking her pressed-together thighs right beside her pussy while Siobhan reached around her pressed-back legs to touch herself. Both of us playing around before the main event. No longer kissing, just eye contact and reciprocated gasps.

"Sigurd, I want you to come in me. I'm not playing this time," she leaned up, whispering, elaborating.

"What?" I reeled back a little, pausing my thrusts between her slick thighs.

"Just say yes, baby. Just say yes."

I looked at her then. Pausing.

"I will. I promise."

I entered her then. She smiled, bringing me in, letting me control the pace. Her body was a work of art, in my opinion more so with a dick in her. As I started going faster she gripped at the sheets behind her, holding her other hand on my chest, running through my chest hair and grasping at it as if to garner some purchase. Her small tits jumped with each of my thrusts, and I decided to grab them both by the nipples, even if I loved to see them jiggle freely.

"Baby, I'm going to cum." Siobhan's eyes focused on mine. She had a mixed expression. Trepidation, fear. Love, yearning. I felt that I must have the same feelings reflected on my own visage.

"Do it, Sigurd. I love you."

"I love you too."

I was out of breath, hammering into her with abandon.

I kissed her, our tongues wrapping around each other as I bucked into her again, and again, until I began to unload into her tight pussy. Each stroke was more sensitive than the last one. I could hear from her gasps that she was cumming with me, and she spasmed around my cock, making the stimulation so much more intense. Both of our breaths were ragged with pleasure, but she spoke a little bit before I was able to recover.

"Come in, Emma."

A thud came from the wall with the peephole. There followed silence. More silence.

I pulled myself out of Siobhan. I didn't see any of my seed drip from her. I was entranced by her, needing to be able to see what I'd done to her womb. I needed to see my cum inside her. I reached out, but was guided away by Siobhan's hand, who pulled her panties back over her pussy with a sly look to me.

Still in a haze, I replayed Siobhan's words in my head. What was it that she'd said?

Suddenly I was aware that I could hear footsteps. Slow, light, footsteps. We had left the door open to the room, a room I was now realizing was drenched in the fog of sweat and sex. My skin as well as Siobhan's was glistening with it.

Emma rounded the corner. She wore nothing. Whether she had just disrobed or was already naked when Siobhan called for her, I was unsure. I wasn't sure why she was called in. I saw concerns similar to my own on Emma's face, but she looked fucking horny. Her fingers were occupied between her legs, if just idly making some circles around her dripping pussy. She was pale and gorgeous and I realized that I was getting hard again. Siobhan could tell too.

"Come." Siobhan pulled a finger at Emma and it was like a puppet had been pulled on a string. She took off the panties then, holding her hand to keep in my sperm.

"Emma you're going to dig that all out of me with your tongue and then give it back to me in my mouth, okay?" Emma nodded in a daze. She panted, eyes darting between me, my cock, Siobhan's sweaty naked form. She began staring at Siobhan's hand covering her cum-filled snatch. I was frozen at this scene. I didn't ever think I would hear these words from my girlfriend about my sister.

"Has my boyfriend ever cum inside you?"

"Only in my ass."

"Yes, I saw that." She removed her hand from her entrance, and I finally got to see my cum slowly bud out from her. I'd really put my seed inside her, and was disappointed that it was going to be inside of her for so little time. But, hold on a second, what? When she came to me in the kitchen, she knew that my sister and I had just fucked, but sh-- "After you eat my cunt, I'm going to inseminate you, Emma."

Emma and I both froze then. Her tongue had just reached Siobhan, and I could see my cum dribble onto the tip of it. She managed to stammer out, "Ins-inseminate?"

"I got the idea from you, my dear," She ran her hand down my arm, "I'm going to tongue-fuck your sister with your cum until she's pregnant."

Emma began to lap at Siobhan's pussy excitedly, her thick ass in the air. She was beet red, but kept looking at myself and Siobhan.

"Don't miss a drop, babe. I want to make sure that you get everything inside you, too." I was sure that I saw Emma quake at those words.

"I don't understand this."

"You want to fuck your sister, Sigurd. And I want to help."

I had no words to respond to that. Emma and I had been going way too far with what we were doing, but I was able to compartmentalize it because it had been just us doing it. Having Siobhan talk about it, at all, made me feel like I was about to go insane, but why wasn't she mad? Why wasn't she condemning Emma and I for cheating, for incest?

"When we used to date she told me about the one hookup she had with a guy. She told me all about him, how he fucked her harder than she'd ever been fucked," She started to breathe heavier with Emma between her legs, "How she wanted him to come inside, and he clearly wanted it too, but he didn't.

"Now I know that it was you. She used to whimper your name in her sleep -- Sig, Sig -- I didn't know that they were sex dreams at the time but now I know. You also talk in your sleep but it's usually nonsense. You're both so similar, and I love you both."

"What does you tongue-fucking my sister have to do with this?" I asked, feeling like I had missed an important story beat in my own life, and that I could make this plot make sense if I could just have Siobhan connect the dots for me.

"You won't have any reason to not cum inside her." Siobhan squealed a little at the end of that from Emma's oral stimulation. Panting, "And when she starts showing I'll know that I got her pregnant at least as much as you did. "

With that Emma crawled over Siobhan's body, chin dripping with juices and my cum. She leaned over my girlfriend and kissed her with incredible zeal, tongues rubbing against one another. Siobhan sucked Emma's tongue, lightly biting it, and then rolled them both over.

Emma was flustered. Gasping, she looked at Siobhan, who she could see moving down towards her pussy with a mouthful of incestuous cum. I was rock hard.

Emma reached for my hand, and I took it. She seemed to calm down some, but was still trembling, breathing like she had been running a marathon. I watched as my girlfriend put her mouth to my sister's pussy, at first just darting the tip of her tongue along Emma's clit and labia.

Emma was overwhelmed. Turning to me, "Oh Sig," left her pleading lips between moans as Siobhan ramped up the movements of her tongue. "Oh Sig, I'm going to have your baby."

I kissed Emma then, thinking back to when we were both on the other side of the wall, when she was cradling a handful of my cum and clearly pondering whether to put it inside her. I realized then that if she had actually lifted that hand to her entrance, I wouldn't have stopped her.

"You're going to get pregnant today," Siobhan was done with her tongue for now it seemed, and she moved up Emma's body like a cat that had pinned its prey. She pried Emma's mouth open with one hand, and let fall the saliva, Emma's juices, and the last of my cum that had been in her cheeks. "Swallow that." Emma obeyed, overwhelmed.

They kissed again, and I began to rouse from my position as voyeur.

Every muscle in my body was a tense spring as I made my way between Emma's legs. Siobhan was straddling her, her butt on Emma's abdomen but with most of her weight was mostly on her knees as she continued to mess up my sister with steamy kisses.

Both of them were dripping. I couldn't see any of my cum on Siobhan, she'd been well-cleaned, but Emma was another story. My mind broke when I saw her perfect little pussy dripping with cum. My Emma was possibly going to be a mother because of Siobhan.

It took me a moment to register that Siobhan had turned her head to me, clearly enjoying my reaction to her work, leaving Emma still gasping and moaning my and her names, begging for more. She smirked at the obvious sexual power she had over the two of us. Her eyes repeated words that she had said to me at least a dozen times before: "take what you want."

I moved to the two of them, Siobhan turning back around to watch Emma's surprised reaction when I entered her. That particular reaction ended up coming from Siobhan, however. Wrapping my arms around her thighs, I lifted her up, folding her knees to her chest and pinning her mid-air, her back to my chest, legs pointed up. Once she realized that she was going to be the one getting fucked, her body lost its poise, and I could feel her trying to grind against my cock that her smooth pussy rested on.

"Emma?"

"Y-yes?"

"Suck my cock."

Emma had me fully in her mouth almost immediately, sliding down the bed like she was in an auto shop to take me in all the way, her face looking up at mine and Siobhan's as my balls slapped against her chin.

Siobhan began to touch herself with her free hands, moaning as she furiously massaged her clit. This was not my design for her right now. Denial was a tool in the bedroom that I was always loath to use. I wanted to fuck a lot more than I wanted to tease, even if it was fun to see her squirm. With a third, this was made a lot easier for me.

With one hand still wrapped around her legs to pin her in place, I batted her hands away from her pussy as she tried to make herself cum. "No, baby, you'll get your turn," I whispered to no effect. She tried harder, starting to try and wiggle free of my grasp. I slapped her pussy with an open palm, trying to go as easy as possible as she was probably already quite sensitive, and I was right to be careful. Her legs jumped and I almost lost my grip as her lower half went limp. She again tried to reach for her pussy only to get another slap from me, this one a bit more gentle.

She acquiesced, turning her head around to look at me, tongue out and face incredibly red. She trembled in my arms as I held her there, her face etched with desire. I could see a few drops of her juices had fallen on my sister's face as she sucked my cock. I kissed the back of Shiv's neck, chewing her earlobes and whispering sweetness to her.

I felt an increase in pace from below, and I saw that Siobhan had wrapped her hands around Emma's head, now dictating the pace.

"You make such a cute cockslut, babe." Siobhan teased down, "It looks like you've been practicing. I remember when you first had me face-fuck you with the strapon. You must have been imagining Sig being the one to do that." Emma was touching herself. I couldn't see it but I could hear her fingers plunging inside her cum-filled entrance.

"You face-fucked her?"

"Do you like picturing that?" I did. "She cried when she asked me, she was worried I'd judge her. The little bubbly domme lesbian wanting to be fucked and used by big, sweaty, man-cock. I thought it was hot as shit, hearing that one little fuck got her that horny for cum." She looked coyly at Emma as she held her head to the base of my cock, cutting off her air. "You don't even have a gag reflex anymore, you little slut."

"Do you still have it, Emma? The strapon?" Emma nodded. Or, moved her head a little in a way that kind of looked like a nod, given what she had in her mouth. "Then go get it."

Emma pulled herself off of my cock and scurried out of the room, and I lowered my girlfriend back down. She lay on her back, hands darting towards and suddenly avoiding her pussy, aware of a possible slap should she begin to touch herself. She grabbed my balls, lightly massaging them, biting her lip as she eyed me up.

"What's the plan now?"

I smiled at that. I grabbed the panties that she'd discarded on the floor and went to my closet, thinking that I remembered seeing a few black silk scarves in there. Two scarves. That would do. I returned to the bed, Siobhan's expression now with a bit more trepidation.

"Sit up." As she did so, I wrapped one of the scarves around her eyes, blindfolding her. She was breathing heavier now, sitting on the edge of the mattress, hands underneath her butt.

Emma had come back with an actual armful of toys, dropping them on the edge of the bed. She looked curiously and with obvious arousal when she saw Siobhan blindfolded, hands clenching each other to stave off her need to pleasure herself. I touched my finger to my lip, indicating that I wanted quiet for what was to come, and tapped the harness that she had brought as well. She stepped into the loops, the black straps hugging her curvy butt in a way that I found incredibly erotic. I pointed to a red silicone dildo that looked like it fit the harness with a questioning eyebrow.

Emma smiled and inserted it into the front slot. She flicked the on button and the thing came to life. On the list of things that had happened in my life recently, seeing my sister don a red vibrating dildo was honestly not even the weirdest one. I did reach down and turn it off though, moving close to her and whispering in her ear. Emma's face lit up.

"Okay now I'm actually starting to feel ignored. Are you two still here?" She was trying to joke, but I could see by Siobhan's legs pressing together that she was desperate for it.

"I'm sorry to keep you waiting, my love," I took her hands from underneath her and laid her wrists parallel on the second silk scarf, tying a knot quickly, leaving one end loose and ensuring the knot wouldn't get tighter by her struggling.

She moaned as I delicately cut out the last of the slack from the knot, and began to struggle against it in a protest that I recognized as her enjoying fighting against me. We did have a safeword, "asparagus," and she could snap her finger or tap out if she wasn't able to talk or breathe that indicated the same thing. Emma moved behind where Siobhan was sitting and embraced her, one hand running through Shiv's dark hair and the other draped over her shoulder resting between her breasts. "But I'm not sure if we should be rewarding you right now."

"Nooo," she moaned, going to stand up. Emma had her by the hair, and she squealed at the resistance, falling back to the bed. "But I've been good Sig, I've been good for you."

"You said that you saw me cum inside Emma. Good girls don't spy, do they?"

"I--" her breath caught as her body shivered at the thought of being denied even longer. Emma stuffed Siobhan's mouth with her panties and guided her by the hair to the center of the bed, tying her wrists to the bed frame.

"You also tried to get a girl pregnant when you already have a boyfriend." Emma said, scolding Siobhan while also almost buckling mid-sentence at the arousal from the memory.

"Yes. A good girl wouldn't do that."

I took this moment to leap between her legs, planting kisses on her inner thigh and caressing her waist and ass. Emma began her own campaign on Siobhan's torso, licking and pinching her nipples. While at first Siobhan would press her body against ours and let out tender moans through the underwear in her mouth in a response to the foreplay, she began to resist when she realized it was only foreplay, and that this was intended to be a drawn-out affair only to tease her further. I held down her legs for this, and alternated between licking her thighs and labia or blowing on her clit. Emma straddled her, red dildo pressed against Siobhan's abdomen, kissing and biting her neck and nipples. I don't know for how long this continued, but I eventually broke the spell. I took out her makeshift gag, soaked in saliva, and put it in Emma's mouth, something that caught her very off guard. I wondered if I had made a mistake then, if Emma wasn't willing or possibly even able to sub for me and still top Siobhan at the same time. She looked away and put a hand on her cheek, face growing red as she brought her other hand to her naked chest. Not a mistake.

Now ungagged, Siobhan was begging for release. For us to fuck her cunt or asshole, finger her until she came, or suck on her clit. I smacked her in the face with my cock on her lips and she immediately stopped begging, letting out a shocked cry of ecstasy, and letting her tongue run up and down my shaft. Siobhan's face was again slapped, this time by Emma's strap-on as she moved up to have her pelvis positioned over Siobhan's neck. She took both of us in her mouth, drool coating our members. I pulled out, and went back between her legs.

"Sig?"

I leaned forward, putting my right arm underneath her. Emma saw what I was about to do, and moved away from us. I slapped Siobhan's clit with my cock, eliciting a silent shake throughout her body.

"Yes. Please, I want you."

"Do you think you've been patient enough? Are you certain that your punishment should be over?

"Oh god yes Sig. I know it's been enough. I need your cock inside me."

There really isn't a better queue than that. I entered her as slowly as possible. She wrapped her legs around me, barely able to breathe. She was soaking wet, and I could feel her juices gush and coat my abdomen as I thrust into her. Clutching her slender form to me, thankful I didn't have to tell her to hold on, I lifted her with one hand and steadied myself with the other, flipping both of us over without straining the wrist restraint or putting any weight on her. She was now on top of me, able to bring her wrists so that they were both on my lap now, but sat almost completely still. She rocked slightly back and forth, but she only really came to attention when Emma suddenly grabbed both of her asscheeks and parted them, steadying the tip of her strap-on to Siobhan's asshole.

"Emma, I'll let you take the next creampie he gives out. Please coat that thing and my asshole in his cum before you assfuck me. It's only my second time and I want Sig's special lube." She giggled out.

I slapped her in the face. There was no real force to it, but I saw the earthquake effect that it had on her body and felt her tighten around my shaft. Her boldness was a front, and I was enjoying tearing it down.

"Aahh!" She cried out.

"You get told what to do, Siobhan, not the other way around."

"I'm sorry Sig," she gasped out, pulling at her wrist restraints, as if trying to bring them to her face and hide herself from us. "I'll be good."

"That's right. You're a good girl. Just this once, though, I'll let you get your way. You've been really good, haven't you?"

"So good, please, Sig." She purred, moving in to kiss me, the cheek where I slapped her already turning a deep red. She was always calling me Sig in bed now."Emma, do what she asked of you." I said between Siobhan's sloppy kisses.

Double penetration was a novelty for all three of us, so I wasn't really sure what to expect. I had enjoyed the pressure of feeling a partner's buttplug when I was having vaginal sex, so I thought it might be as good, but the dildo's vibration elevated that feeling a thousand-fold. Siobhan's pussy seemed to transfer that vibration, elevating my pleasure to an entirely new kind of experience.

"Ohhhh fuck! Oh fuck me. Baby I'm already com-- Mmmmm oh my g--," Siobhan was trying to talk in full sentences but it just wasn't happening for her until she managed to spit out. "Say that I'm a good girl."

"You're my good girl, baby."

Her legs quaked again as we fucked her, responding to the simple but tender affirmation.

The fact that I could feel Emma's thrusts into my girlfriend did give me pause. A very brief pause. My sister was harness-deep in Shiv's asshole, and while that was strange for a lot of different reasons, none of them mattered because whenever she plunged into her ass, it squeezed my dick from shaft to tip and made my toes curl. Emma was clearly enjoying herself. As she rocked her hips, her abdominal muscles tensed and flexed with the effort of rough anal penetration. She slapped Siobhan's ass and grabbed her hair with the same hand, pulling her up from where she lay collapsed on my chest and arching her back.

Siobhan, still blinded by the scarf, twisted her head around towards Emma, cooing from the pain and sudden closeness. Their faces nuzzled against one another, and I realized the problem. I put my hand to Emma's mouth, prying it open with little effort, and pulled out the wet ball of panties that I'd stored there. Emma looked to me for permission, and seeing that I was staring and wasn't stopping her, she pulled Siobhan's head back even further so that it was just below hers, and spat in her mouth. Siobhan swallowed it unhesitatingly and went in for a kiss, locking lips and surprising Emma, even though she was the one who was able to see between them.

We had turned down the pace slightly, and after watching them kiss for a minute while I thrusted upwards, I decided that it was time to switch things up. I ripped off Siobhan's blindfold, leaving her blinking and looking between Emma and I, still with my sister's tongue down her throat.

I kissed and caressed Siobhan's chest and neck, crawling up her body to meet the lips of her and my sister. Emma was looking at me much like I had looked at her after I stuffed her mouth with Siobhan's panties; she was concerned that her kissing my girlfriend like this had upset me. That amused me. I really just found it super hot. I'd be a bit jealous if I didn't know how devoted they each were to me, but my cum had made its way into both of their mouths and wombs today alone. I felt like a million bucks.

We explored each other with our tongues, each of us openly enjoying the novelty of having more than one partner to get so intimate with, connected together. I picked up the pace as I focused on Siobhan, feeling that she was approaching orgasm.

"Ohmygodogmygodohmygod" Siobhan's nails dug into my chest, and I pumped her even harder in response. She dove at me, smothering me with her lips, hungry. Emma began increasing speed in kind, spreading Siobhan's ass for us to thrust further into.

Siobhan suddenly froze, and I felt a squirt from her pussy as she began to shake and cry out with pleasure as she came. I don't know exactly how you'd delineate it, but for what felt like 45 seconds she was either having a chain of orgasms or a really intense one.

Her arms fell heavy onto my chest after this period of stillness, and she rolled to the side and off of my cock and the dildo in her ass, gasping at their respective removal. Sensing the shift, I undid the knots around her hands in a few seconds.

"That was amazing but I need a rest," She covered her face, beet-red. "I'm sorry I spied on you. I want to see you two do it again."

I couldn't help but smile. I pried her hands away to kiss her playfully on her cheeks. She blushed even harder. Emma removed the harness as I was giving Siobhan attention and then embraced me, kissing me on my shoulder and neck. I turned to her, letting her at first get on top of me, sitting on my cock so that it ran against her labia, before bringing her closer and rolling over so that I was on top again, just like I'd done before.

Siobhan cozied up beside my sister, running a hand under her ass and another around her ear. I slapped her pussy with my cock, making her jump a little.

"Do you want this inside you?"

"Yes, Sig."

"How do you ask for it?"

"Please Sig, fuck me with your cock. I need it," Emma, used to being the domme, looked embarrassed at this. I could feel fire in my abdomen, testosterone spiking at that look on her face and at what she'd asked me to do to her.

"That's a good girl." Emma shivered at my words, pulling me in.

"I think she's ovulating right now." Siobhan said as I entered my sister. As I fully comprehended the gravity of those words, I was already balls deep.

"You-- looked at my tracker?" Her voice was airy, adjusting to me being inside of her. I suppose she hadn't been directly stimulated since Siobhan gave her oral earlier.

"Are you ovulating?" I asked, slowly stirring Emma up, beginning to move inside her.

"I-- I haven't checked in a while. It's been a while since my period though, so maybe." Her tone was almost dreamy. Both her arms were draped over my neck as she looked me in the eyes, letting me fuck her.

"I can smell it on you. It's like you're a little bit sweeter for a couple days of the month."

"If I'm ovulating--" She stopped herself, still looking at me.

"What?"

"I might get really pregnant."

"Yeah."

"You're going to come in me today."

"Do you want that?"

"I-- can't you tell me that you want it?"

"You first. I want you to ask me for it."

"I-- Sig, I-- I want you to come in me."

"You're his good slut, aren't you?" Siobhan cooed in her ear. "You're going to let him knock you up?"

"Yes." Emma looked at me dearly, awaiting to hear what I'd say to her request. "Please, Sig."

"I'm going to get you fucking pregnant, Emma." Her eyes widened and I started drilling her faster, bending my back down and using an arm underneath her torso to pull her upper half off the bed so that I could ravish her small breasts with my mouth. Her skin had a sheen of sweat over every inch, and I tenderly licked it off of her tender curves, sucking and biting at her shy nipples. She made sweet little cries all the while, and I moved myself further upwards. I bit down on her neck, getting a cute gasp as I chewed and sucked.

She squirmed at this. "Hickeys, now?"

Siobhan moved in to join me, "Who do you need to hide them from?" As she clamped down on the opposite side of Emma's neck. Emma squealed with pain and pleasure as we worked her. I massaged her breasts and rubbed her nipples, moving up to kiss her jaw and then chew on her lower lip.

"It's coming." I whispered. "Are you ready to be a mother?"

Emma was too struck to speak. I relished her shock and noted Siobhan's own glee at Emma's expression. I was nearly out of breath with the ferocity of our lovemaking, my balls slapping against her and I pistoned myself as deep as I possibly could into her cunt. She was looking at me, her eyes a mix of lust, love, and fear, and I knew that this was what I wanted.

I came deep inside her, still jackhammering away as my cum flooded her pussy. I had never cum so hard before. Holding back with all this teasing had nearly pushed me to the brink, and knowing how wrong it was for me to cum inside Emma -- my sister -- when she might be ovulating -- in front of my girlfriend -- made me shoot with everything I had.

She was still wordless as I filled her up with cum, her eyelids fluttering as she desperately panted, moaning between inhales. Her spasms around my cock gave me the impression that she was cumming with me, although she was still almost frozen. I collapsed on top of her, and almost would have stopped there if it weren't for my near-involuntary reflex to keep thrusting inside this girl. I kissed Emma again, cutting off her moans and halting my movement, letting us rest breathlessly together in each other's mouth, thinking of nothing but my love for her and the thought of my seed invading her womb.

December 18, 5:50PM

"That was hot as fuck." After about 2 hours of semi-wakeful cuddling and a few glasses of water all around, Siobhan was the first one to break the silence as she lay herself resplendent across my chest, legs entwined in mine.

"What part?" I brought her in a bit closer to me as I lay on my back, cupping her ass to scooch her closer.

"All of it, dumbass."

I kissed her forehead, "I agree. I'd love to go more but I think I'd need an IV for it -- I'm feeling a little bit more than just drained."

"I'm guessing I could make it stand firm if I really put my mind to it -- you're underestimating my powers of raw seduction." Siobhan yawned. "But I think I would need one or two IVs too. Maybe an ice pack between my legs for a bit. You two both love slapping my cunt."

"Mmm you make such cute noises when we do it," Emma said, face buried in my neck, opposite Siobhan.

"What she said."

"Well fine. I guess I'll just have to keep letting you hit me." Siobhan shivered a little at her own words, closing her eyes hard as if to pretend she didn't admit what she desired.

"Speaking of things continuing, what are we going to do next?"

"I already told you I'm too sore for--"

"Not what I mean. Like in the next few months and years. Emma's my sister. I cheated on you. You watched me cum inside her. You two used to date."

"I knew what you meant, I just didn't want to be a bummer. I don't know."

"How do you not know?"

"I just wanted you to take what you want. That's all I've ever wanted for you, Sigurd. Sig. I like Sig, I know I just called you that to tease you but I think it's cute."

"Siob--"

"I mean it. Emma -- one of the lezziest of lesbians I've ever known, suddenly wanted to get creampied and knocked up after an encounter with some guy she saw over winter break. You haven't seen her since that same winter break two years ago and have the exact same fantasy. I wanted you both to get what you want, and I was pretty sure you wanted it from each other."

"Why did you leave, then?"

"I left because I was upset and confused and needed space. I also didn't know if I was right and I wasn't about to ask 'hey, do you two have deep-seated psychosexual desires that can only be sated by incest creampies?' and risk being the crazy incest ex-girlfriend to your family if I was wrong?

"No. If Emma didn't want to get knocked up, I would have monopolized your cum. I love you Sig. And I would have worked to make everything normal between me and her to make you happy. I actually fantasized about you two fucking while I was away. I knew it right away when I got back though. Seriously -- she reeked of your cum. I confronted her when you went to drop off the truck. Got her to agree to an alliance for a bit. Told her it'd be worth it. Pushed her to pretend I went to the YMCA so that you two could fuck and I could watch."

"Jesus. Fucking. Christ." Gobsmacked.

"You don't get to judge me. Adulterer. Sister-fucker."

"No, no, I'm not judging you. I'm fine. I mean, that sounds crazy, but I fucking love you Siobhan."

"Good." Her breathing purred as she cozied up to me, making an effort to maximize our skin-to-skin contact.

"What did you tell him to get him to cum in you?" Emma asked. I wasn't sure if she was hiding her face and speaking quietly out of shyness or fatigue.

"I told him that if he came in me he would be able to take whatever he wanted. And to do it, because I would break up with him if he didn't."

Emma raised her head up at that. "Seriously?"

"I think it worked out fine. Mind your tone, jilted lover. Boyfriend-stealer. Your hand is pressed between your legs, are you holding in his cum?"

Emma ducked back down.

"You are?" I said, causing Emma to look back up at me.

"You told me you were going to get me pregnant, right?" Hearing Emma say that so tenderly melted me. "I'm holding it in because -- well I actually don't know if it helps -- I want to keep it inside me, Sig. You gave it to me." I kissed her head and wrapped my arm around her.

"And you're sure she was ovulating?"

"Yes. Without a doubt. I told you that she smells like it, I'm really that good. You better be thankful I have a high tolerance for your particular stink." Siobhan made a show of ducking under the covers, running her nose from my junk up to my abdomen, chest, and neck. She kissed my jaw. "I used my period tracker to tell me for my cycle, though. I'm in the clear now, so you only get to have one baby mama for now."

"For now?" I felt her kissing the back of my neck.

"It damn well better be for now. But... I only stuff a girl full of her brother's cum if I really really like him. And her."

"I love you, Sig. I really love you both, I think." Emma whispered. She dug her fingernails into me at her own words. She started to giggle before managing to spit out "I'm ovulating, I don't know what I'm saying."

June 24, 3:00PM - Epilogue

I woke to the sound of the driver's side U-Haul door slamming. Groggy, I realized that we'd arrived at our destination. I yawned and reached for the door I'd been leaning against, unstrapping myself. I dropped down, my shoes landing on the hot pavement of the New York City street. I hadn't been asleep for long and I was in long-haul mode, but I felt full of energy nonetheless, letting myself take a moment to get my bearings. The road was a long one to get to this moment, but I had been waiting since the winter to be exactly where I was right now.

Okay, so, my parents. They ended up getting their name on a patent for a new type of booster. A billionaire bought the company they worked for and sold the whole thing for spare parts, the patent being one of the high-value assets that went to auction following the company's dissolution. Their booster never made it to human trials but I'm told they were quite hopeful about its efficacy, so it's a shame that the patent ended up in the hands of the biggest vaccine producers on the planet who did nothing with it, and instead pumped out their own in-house recipe.

For me, it had been a long semester. I was not able to find a similar job and actually went back to serving. Similar hours, thankfully, but worse pay and not as good on a resume, and I was drained all the time. Thankfully, our university fucking loved Siobhan, and they told her she could work completely remote whenever she wanted and offered a full-ride scholarship that we were allowed to allocate to rent. We lived together in a shitty bachelor apartment and spent a lot more time appreciating the other's cooking rather than takeout until one week ago, when I graduated and Siobhan's semester came to a close. We'd been on the road to our new home ever since.

Between shifts and preparing to defend my thesis, I had managed to line up an internship with an exceptionally well-regarded restoration company in my field. In New York. Moving to New York City was not something I'd ever expected to do in my life for any reason. In terms of my prospects, professionally, it would be feast or famine, but now I had unexpected support. My sister talked our parents into helping us put down a down payment for a duplex condo, paid largely in part with our parent's earnings from their company's stock buyback prior to its dissolution and their own bonuses for finishing the project.

On that duplex's street now, I looked around, recognizing that I was a few doors down from our place but unsure in which direction. I saw two women embracing in front of some stairs just behind where we'd parked. I smiled and began to jog over.

Hair now pink and trimmed a bit shorter, Siobhan wore black even in this heat, sporting a bralette and short leather jacket with ripped jeans.

In her arms was my sister, Emma. Radiant. Emma was 5'0" flat, but beside Siobhan just looked a little bit short. I'd last seen her two months ago when I'd visited her here, at her old apartment. Now she was 26 weeks pregnant and showing, wearing what she'd presumably been wearing while at work earlier today: a white button-up shirt and a tight-fitting blue skirt that somehow made room for where our child grew inside her. Her breasts had a newfound fullness to them that I never knew I wanted, but I found it tantalizing to imagine how they now tasted.

We embraced then, and I kissed her on the lips, feeling her belly as I pulled her up into me. She was incredibly alluring when so visibly pregnant, it made me want to put another baby in her already. I'd seen Emma constantly since we had last parted. We video called almost every day, and often sent each other videos of us masturbating or, in my case, various videos of me and Siobhan. It was fun to do something so brazen, but being able to feel her, touch her, smell her, feel her was a reminder of how much I had missed her.

"Been a while, Sig." Emma said through a coy smile, the two of us pulling away from one another. We were still in public.

"It has."

We all entered Emma's side of the duplex, already furnished if still a bit unpacked. We were all over each other, gently but with obvious passion.

"You're clearly raring to go, Sig."

"He is," Siobhan moved in close to Emma, hugging her around her belly, whispering. "He's not been letting me cum for three days, but he hasn't let himself cum either. I think he's pent up."

"Hmm." Emma considered those words, and looked at me pensively. "So, should we tie her up and make her watch us fuck? I have some vibrating nipple clamps that I've wanted to use."

"I like that. Especially the clamps, I was going to suggest a vibrator in her pussy on the lowest setting to tease her, but the nipples are a much better idea."

"I can't believe how fucked up you two are, can't you ever just pamper me?" Siobhan squirmed and looked away, clearly excited over the fantasy but nervous about how long she could go without release. "But... I guess if I get to watch it would be kinda hot to be tied up." She got redder. We all made our way into the bedroom, shedding clothing haphazardly as Emma led us inward to her side of the duplex.

I thought about the future. The plan was for me and Shiv to live in one apartment, and Emma in the other, faking normalcy. Emma told our parents that she had found a sperm donor -- deciding to become a mother on her own without needing to be in a relationship. I wasn't there for the conversation so I don't know how she sold them on it but they became incredibly supportive even if quite shocked at becoming grandparents so late. They are also the straightest people I know, so my guess is that for them "lesbian = behavior I inherently can't relate to, or understand", which was helpful in covering up the true parentage. The duplex was a long-term plan that we somehow finessed into happening before the pandemic even ended, but it let us all fuck without anyone picking up on it.

Emma had been insatiably horny but was incredibly sensitive, coming to orgasm with the gentlest of my thrusting into her. Something about her was ravenous that day, a primal expression on my younger sister's face as she let herself be fucked senseless spoke of her naked desire to be filled. I'm glad that Emma had set up the bed with restraints ahead of time, as Siobhan lay on her back, spread-eagled, as we fucked on top of her. Siobhan was gagged with a metal bit and naked but for a pair of panties that served to hold two bullet vibrators, one for her cunt and the bigger one for her asshole.

"Ohhhh fuuuuck Sig!!" I felt Siobhan's tongue lap at my balls as I fucked Emma hard from behind, eliciting delicious moans from my sister as I ravished her. She was squeezing me incredibly tightly as she came, and I could feel Shiv's tongue reaching for the fluids that were running out of Emma's cunt and down my shaft.

I might have been fucking Emma hard, but I was gentle as I held under either side of her belly, where the proof of our love lay inside her. Emma was so bold and open in her reactions it just turned me on all the more, squealing and begging for me to fuck her harder and deeper in between gasps and cries of overwhelming pleasure.

"Aaaaa!!!!" Emma slammed her ass back against me with force as she came again, holding my cock deep in her pussy as if to ground her from an electric shock as her limbs shook with orgasm. She was pressing herself against me with enough force that she was spreading herself apart for me, putting her stretching and twitching asshole on display. I sensed that she was approaching her limit and I moved up to her face, still inside her.

"Sig, baby, I love you." She breathed into me as we kissed with a lazy tongue.

"I love you Emma. I'm so glad that we're making life together. You are perfect to me."

"I feel the same. I want more of you in the world, Sig," She removed me from inside her with a whimper. "And I'm so lucky to carry you inside me."

"Need a bit to recover?"

"Unfortunately, yes. That felt fucking crazy. Maybe it's just been a while, or maybe it's the pregnancy, but I've never cum that hard. Ever." She moved off of Siobhan, sitting beside her and admiring her breasts as the nipple clamps attached to them buzzed away.

I moved back, Siobhan emerging from between my legs as my balls fell from her mouth and were dragged across her face. She looked so fucking hot, the expression on her face screaming that she needed just a little more stimulation to reach orgasm. I unlatched the bit gag.

Before she could say anything, I filled her now-unbound mouth with my cock. Just like how I rammed into Emma's throat when we were alone that first night back at our parents'.

"Can I show you something, Sig? Shiv will want to see it too." Emma straddled her now, shuffling up Siobhan's body, one hand under her swollen womb, the other removing the vibrators from our restrained lover's person. I gave Siobhan chances to breathe between strokes, taking my time as my sister moved towards me.

"I only found out about this a couple of days ago," Emma cupped her still-small but engorged breasts from below, thumbs right above her nipples. They were still folded in on themselves, areolas inverted. She squeezed, making an audible gasp as a couple drops of white-yellow liquid began to pearl out from her. I froze mid-stroke at the sight, unable to keep up a pace as my eyes fixated on my sister. "They didn't get that much bigger, but my boobs are working just fine."

"Milk?" Both Emma and I were surprised at Siobhan's shocked words. Her expression was a mix of amazement, lust, and something else as her gaze fixed on the beads of liquid that came out of Emma's breast.

"Just because you're ungagged doesn't mean you get to talk, love." Emma smiled, and repositioned herself overtop of Siobhan, and I felt her mouth completely abandon my cock in favor of Emma's wet cunt.

"And it's called colostrum. It's almost milk, and while it develops long before birth it usually doesn't come out this early, I think. But I--" Emma caught herself to gasp at Shiv's tongueplay. "I love to squeeze my tits when I masturbate, and pinching my own nipples might have stimulated it enough to come out a little early. Or maybe I'm just a freak." She giggled.

"I--"

"Taste it. It's a bit salty."

I didn't hesitate. I was lapping up what drops had dribbled from her left breast, holding her hips firm. I regretted that Shiv couldn't see us with Emma's belly blocking her view, but I loved every drop that my lips pulled from her tits. Emma wasn't wrong about there being some salt to it, but it was still shockingly sweet. Her nipples stayed inverted, when normally they'd be erect at this level of stimulation. It must have been just a dozen drops more that I managed to drain from her, but it was glorious. I didn't know I would get to do this so soon, I couldn't be upset at the amount she'd produced. I was entranced, barely able to make out her passionate words as the suction and my tongue on her sensitive nipples made her squirm.

I swallowed the warm liquid I had pulled from her, and moved on to her second breast, draining it, too. Emma's cries became nearly deafening as Siobhan's tongue worked inside her, and I could tell that it was again becoming too much stimulation for her. I pushed her back gently off of my girlfriend to little defeated moans as I unlatched from her right breast. Siobhan was a mess, now, tongue still out and desperate for a lover's attention. I lowered my mouth to hers, stopping right before our lips met. She squirmed at the teasing, clearly unsure as to why I'd halted. I parted my lips and let Emma's milk drip into her mouth, electrifying her as she realized what I had gifted her. I kissed her then, tasting both of my sister's juices on my girlfriend's tongue.

"Don't swallow that yet. Emma, remove her restraints." My sister obliged, moving excitedly to remove Siobhan's wrist and ankle cuffs as I lined myself up again to fuck her throat. She gagged as I entered her, on both the rough outline of my cock digging into her as well as having her mouth full of liquids that she was trying not to spill. I couldn't really feel much different, but I knew that it was my sister's own milk (or whatever) that lubed up the esophagus that the tip of my cock was slamming against. I was still careful to let her breathe, which took a special effort as I was finding it difficult to hold myself back.

"I'm going to--" I grunted as I could feel an orgasm build up within me, thrusting harder.

"Are you sure?" Emma touched my arm, watching the show carefully from beside me. I wanted to ejaculate inside of Shiv's mouth, make her show it off to me before I told her to swallow it all down, but as I looked at my sister her eyes told me that she had something else in mind. I slowed my thrusting but didn't stop completely.

"You should do it inside of her cunt. I want to watch you get her pregnant, too, Sig."

She wouldn't let that happen. No, Siobhan had a hard-set career plan that not me or God were allowed to alter. Emma knew this, why would she bring this up? I tried to object, but I found myself looking into Emma's eyes instead. Fuck she was beautiful. Her ass and hips were always larger in proportion than the rest of her svelte figure, but they'd grown even more ample in the time she'd been growing new life inside of her, something I'd relished while fucking her from behind but once again found myself appreciating.

"I want more of you in the world, Sig. And I can tell how much you love me like this," She ran her hands over her body. "I want you to knock me up all over again, but I want a bit of a break first."

I removed myself from Shiv then, looking down at her. She still looked to be in her subby trance, but I could see a heat behind her eyes. She moved her now-unbound hands to her breasts, squeezing them much in the same way that Emma had in order to extract those first drops from her nipples.

"You can swallow it," Emma spoke for me, then. Siobhan obeyed, not hesitating in the slightest, gulping it down with a rushed excitement. She presented her open mouth and tongue for Emma and I, to prove she'd done it. "Good girl." We both murmured.

"Thank you." Siobhan whimpered in reply, squeezing her thighs together and covering her cheeks with her hands as her face grew a deep red. I moved myself down to her lower half, appreciating her figure. Siobhan was avoiding touching her nipples, likely due to the effect of the clamps. She still wore her underwear, a deep blue pair of cotton panties that had been completely soaked through with help from the vibrators we'd placed in her ass and pussy. I plucked the panties off of her in a single movement, getting her and Emma's attention now.

"You-- Are you going to do what she asked?" Siobhan's tone was a mix of emotions. Emma had stopped straddling Shiv, and now kneeled beside her, watching what I was doing while pinning down Shiv's hands.

"My sister asks for a lot of things." I parted Siobhan's legs at the thighs without resistance.

"You're going to try to get me pregnant?" I lined myself up at her entrance, lifting her ass off the ground and letting her legs wrap around my torso. "We talked about this, Sig--"

I looked at Siobhan again. She had stopped talking when Emma began to whisper to me. I drank her in, visually enjoying her soft tummy, small breasts with pale-pink nipples, and the pout that she always wore on her face. I entered Siobhan, and we both lost our minds at the sensation, both of us freezing after the first half of my stroke into her. She was incredibly tight, and I was worried that I'd cum then and there. Neither of us had cum in days. Our eyes met, and she saw the lust in them.

"Sig, I'm ovulating. For real. If you cum inside me--" I pushed deeper into her, cutting her off.

"I know you're ovulating. You'll get pregnant."

"Mmmm but I can't, we talked about--" I slid myself out of her so that only my glans was enveloped and slammed into her again. Her muscles tensed and she opened her mouth as if to gasp, breasts heaving upwards at the shock of the sudden stimulation.

"I can't wait any longer. I want you to be mine, Siobhan." Pressed on top of her, I was using one arm to hold me up, but I used a free hand to run through her pink hair.

"I'm already all yours. You know that I want your babies but we're still so young--"

She was breathless as we fucked, her pale blue eyes not leaving mine as I saw her cum over and over on my cock.

"Baby I can't get pregnant, I'm not able to take plan B."

I knew that. Side effects. There wouldn't be any going back if I didn't stop myself.

"You can't come in me Siiiiiig--" She grunted out as she came again, her raw pussy flexing around my shaft, inviting exactly what she said she didn't want. I wavered. Emma saw it, and leaned towards me.

"She has a safeword, Sig. Don't pull out unless she uses it." Emma whispered into my ear before biting the lobe. Louder now, so that Siobhan could hear her, "She likes you being rough, can you see the look on her face? I know how much she wants this. She wants to fight back, but she can't hide how much she wants it."

"You're so beautiful, Siobhan." I gasped out, leaving my sister behind to join lips with my girlfriend. "I'm going to love seeing you pregnant. I can't wait to fill you with my seed."

"Sig, you shouldn't, I'm--" She was struggling to find a reason, and finished her sentence with a whimper, biting her lip and halting her speech, looking down to see my cock driving in and out of her pussy.

"My brother is going to unload in you now, Shiv. He's too much of a gentleman to say it, but we can both tell that you'll love it, the dirty little slut you are." Siobhan didn't object to this, her mouth opening slightly, no sound coming out as she came again.

I kissed her.

"Fuck, I love you baby. I love that you're my little slut."

"I love you too, Sig." Her eyes were watery with emotion, "I'm yours. Always."

"Oh god, Shiv, I'm about to--" I could barely get out my words as I moved up the pace, and saw the panic and lust mix on Siobhan's face as her legs tightened around my waist. "Fuck, I'm going to come!"

"Noooooo-- You're gonna get me pregnant Sig!"

White-hot semen shot from my cock, pulsing into the depths of Shiv's pussy. Her back arched up from the sudden sensation of cum flooding her cervix, and I kept going, barrage after barrage propelled into her uterus, much of my seed spurting down my shaft and out of her.

Tremors ran through my body at the feeling of pleasure that came from filling her up, and as I drove into her one last time the tip of my cock stopped at her cervix, her wanting cunt greedily milking the last drops of my cum out of me, spasm after spasm of her own.

I brought Siobhan to me, shifting her up and onto my lap, both of us still locked together and incredibly sensitive. Emma let go of Shiv's hands to let us embrace, and joined in from behind her, her hands running through my hair as Shiv's hands were under my arms, bringing her head to my chest.

We sat like that for a while.

"You knocked me up Sig. You really did it." I couldn't see her face, the side of her head pressed to my chest, and her monotone voice set me into a silent panic.

"Was that okay? I thought-- I thought that might be what you wanted. Siobhan I'm r--"

She turned up to me with her tongue stuck out, eyes closed. A mischievous smile played across her lips, and relief flooded through my veins. "Gotcha." She giggled.

I moved on her face, sucking her outstretched tongue, getting a shocked and then beautiful, loving, subby expression from her as we kissed.

Peeling herself back, she looked at me, smiling.

"You're lucky I get off on losing control, Sig," She moved back down to my chest, ear pressed against me. "You were so scared though, I heard your heart rate triple when I pretended to be angry. You're back to normal now."

"She also has a rape fetish, Sig." Emma stretched herself around, coming in to chew on my neck. "You should stage a break-in or something. Make it seem real."

"Shut uuup." Siobhan nipped at Emma's neck, eliciting a shriek from my sister. "And I think it would be hotter if Sig just forces himself on me as himself, I want to see his face and not a ski mask." She caught herself, realizing what she was saying, and turned a deep red.

"Okay, I promise you that's been noted for future reference. You're really okay?"

"Yeah. I would have used my safeword. There are some things we need to figure out, but that can wait." She moved back up to kiss me again, this time with gentle passion.

"So, about this being a fertile window--"

"Yeah. I told you that you really did it. I like feeling you inside me."

"We should get our nipples pierced." Emma mused as she lightly tweaked Shiv's nipples from behind.

"Not when we're pregnant or breastfeeding. We don't need to risk infections, those piercings take a while to heal," Siobhan smiled at the thought as she spoke, and then looked at me. "I felt you throb a bit in my pussy right after she said that. Looks like you have another vote, Em."

I smiled at that. My turn to be embarrassed.

We eventually lay back down in a mess of limbs and fluids, whispering sweet nothings to one and other as the light from the sun slowly dwindled in the room. We were curled up in a way to maximize skin-to-skin contact, and both of my hands squeezed buttock and breast, although I wasn't exactly sure whose.

As sleep crept in from the edges of my vision, I hoped that it would all work out. The three of us were bonded with one another in so many ways, many of them darkly taboo and in a manner that we could never share with even our closest family, even our children. All of our children. I knew that I would do anything for these women that I held in my arms, and I'd witnessed them do anything for me. For now, knowing that was enough to assuage my fears over the future, and I let myself drift off to sleep beside my sister and my girlfriend.

The End

A Second Author's Note? Seriously? // Thanks for clicking! This is a first-time work of a long-time fan of amateur erotica. I had an idea for a short scene (HA!) and some real affection for these imagined characters, so I did the best I could. Some wrist cramping later (typing, I swear!) I found myself with this story and felt the need to share it. I know my writing has a few quirks, but I hope that they didn't impede on the story coming to life for you. I hope you enjoyed it, and I'd love to get your thoughts in the comment section below. I think if I ever do this again I'll need an editor -- self-editing is hard! I should have just made a forum post asking if someone was willing to take a chance on this fairly-specific kinky story of mine. Anyways, that's all from me for now, dear reader. Thanks again!
