Change of Plans Pt. 02

Finally here. Thanks for your patience!

Part 2

In a lot of ways, it was a hungover morning after like any other. I groggily opened my eyes, scowled as I saw the sunlight streaming through my window and making my head throb, and instinctively reached over to grab my phone and check it.

Then I noticed that my arm was bare -- I was naked, not wearing my pajamas. I looked down the bed and saw my clothes from the day before strewn everywhere. And right in the center of my sheets, a sizeable wet patch.

All of a sudden, the memories came flooding back.

Charley and I had sex last night.

I groaned and shut my eyes, turning onto my back.

How on Earth did this end up happening? I know it had been an... eventful week, but surely there were a few steps we skipped in between walking in on each other masturbating and actually fucking?

Did Charley like me now? Wait... had she liked me the whole time, too? That seemed unlikely given my physical traits and lapdog personality as a kid, but what the hell did I know anymore? No, it was probably just a drunken misstep, but I just couldn't stop my mind racing. New thoughts were being generated faster than my hungover brain could deal with them.

Unfortunately, I wasn't going to get the chance to organize said thoughts. I heard a knock on my door, and it didn't take a genius to figure out who it was.

"Just a second!" I yelped. I quickly got up, scrambled over to my wardrobe and threw on some clothes. After a failed attempt to fix my bed head in the mirror, I sighed and ran over to the door.

Sure enough, when I opened it, there she was. "We need to talk," Charley said.

Just seeing her triggered my fight or flight. I wasn't even close to being prepared for this conversation. "Ah... okay."

She strode over and sat down at the edge of my bed, and I cautiously sat beside her, my heart pounding. She looked like she'd been awake for a while -- hair brushed, light face makeup and fresh clothes, an ensemble which I was relieved to see did not include a pink crop top. She was back to her usual pristine self -- a far cry from the beautiful, red-faced mess she'd been last night.

She cleared her throat. "So. Last night."

I stood up quickly. This was too much. "Charley, I don't think I can -"

"Sit down," she ordered.

I sat down.

"It had been a... strange week," she began. "We were very drunk. It was a huge mistake, of course... but it doesn't have to be a big deal. We're both reasonable adults and we can be mature about this."

Always the rational one. I just nodded. I didn't trust my voice to come out as anything except a squeak.

Unfortunately, it didn't seem like she had anything else to say either. After a few seconds of awkward silence, she turned to me and shot me an exasperated look. "Are you gonna say something?"

Uh oh. I gulped. "What do you want me to say?"

"I don't know! Anything. How are you feeling about all this?"

I groaned inwardly. "I honestly have no idea. This is all insane, Charley."

"Well... I need you to help me figure it out, okay?" She sighed. "This is all came so unbelievably far out of left field."

"Okay, okay..." I began, taking a deep breath. "I agree with you, pretty much -- it had been a really strange week. Honestly, I hadn't expected you to fly home at all, and then I walked in on you touching yourself... it threw me off, to say the least." I remembered her questions last night. "And I think you already know that my actions later that day were not entirely unrelated."

She nodded, and I winced. The crazy events of last night lessened my individual embarrassment, but knowing that my stepsister was aware I had masturbated to her was still not the best feeling in the world.

"Anyway," I continued. "Then we're sitting on the balcony last night, and you keep bringing up the masturbating and weirdly complimenting me, and so when you kissed me out of nowhere-"

"Uh, what? When I kissed you?" she interrupted. "Please."

"Believe me, my memory of the moment is pretty vivid. You initiated it. Trust me, you never forget your first kiss with your stepsister."

She gave me a look, clearly not appreciating my joke. "Whatever. You were saying?"

"Right... so yeah, we were both super drunk and you kissed me, I had already been feeling weird emotions and got swept away in the moment, we had awkward, amazing sex and here we are the morning after." I grimaced, realizing I'd been rambling. "Extremely hungover."

Charley paused, looking at the floor. "You thought it was amazing?" she asked quietly.

I felt my face grow hot. 'I mean... it wasn't bad. I think." I hadn't even really considered whether it had felt good for her whatsoever. "Right? Was it just me?"

"No." She blushed too. "I know I said I'd been getting a bit of action at Stanford, but actually it's kind of... been a while. I broke up with my ex last November and haven't done anything since then. Too busy. So yeah, it hit a little different for me. I'm sure it's similar for you."

"Uh, yes," I replied. Now didn't seem the best time to bring up that last night had actually been my first time ever.

She went silent for a moment, and when she spoke again, there was something new in her voice. "The important thing is, you don't want to ever do it again, right?" she asked.

Her question felt like an electric shock. If I didn't know her, I would have guessed from her words and tone that she was asking that question to confirm that like her, I also didn't want to.

But I did know her. "But... you do?" The realization almost made my brain explode.

Charley wants to hook up with me. Again. A drunk mistake is one thing, but to sit here the morning after and want to make that same mistake again... I could feel my head begin to throb.

Her eyes widened after I saw through her meaning. "No! I don't think so..." She hesitated. "I was just really horny, and it was really good, and I was just thinking that it's not like it would ruin my plans or anything."

Jesus Christ. I couldn't believe she had actually considered whether having sex with her stepbrother again would fit into her plan or not. And yet, knowing Charley, I guess it really wasn't that surprising.

"We're adults, right?" she continued. "And we're not actually related. I mean, stepsiblings can legally get married."

My heart stopped. "What?"

She saw what I was thinking and slapped my leg lightly. "I'm not saying I want to marry you, you moron. I'm just saying that if getting married isn't wrong, then surely sleeping together occasionally wouldn't..." She stopped and laid her head in her hands, groaning quietly.

I instinctively wanted to rub her back, but at the same time I didn't think touching of any kind would help given the circumstances. "... you okay?"

"I just realized that I was genuinely trying to convince my little brother to fuck me again." She chuckled painfully. "What's wrong with me?"

I took a deep breath. "There's nothing wrong with you. And you're not wrong, what we did really wasn't that bad."

She lifted her head and looked at me, catching my tone. "But we can't do it again."

A small voice in the back of my head screamed at me for being such an idiot. I mean, I had fantasized about something like this happening for literally my entire childhood.

But the rational part of me fought back. I remembered those times I'd thought about her, all the guilt that had caused. How unbelievably shitty it felt to walk up to her, Mum and Dad everyday like everything was normal. Like I wasn't violating her in my mind. It wasn't just because she was any other girl I couldn't have.

We were literally family. I mean, Charley and I weren't actual siblings, but... we really kind of were. It felt like that at least. And that meant that as annoying as it was, this would never stop feeling wrong.

"Yeah." I breathed out. "It would not be a good idea. I mean, we have an... alright relationship, right? It wouldn't be smart to mess with that. And this isn't even considering what would happen if Mum and Dad found out."

"Oh my god." She grimaced and looked up at the ceiling. "I don't know if I'm ever going to be able to look them in the eye again."

Welcome to the club. I didn't know how to respond to that, so I just sat there silently.

Looking over, I watched as she sat leaning back, staring at the ceiling light and breathing deeply. And I couldn't help but flash back to when she was doing the same thing last night, only in very different circumstances -- sat up and hugging me, our bodies tightly pressed together as we both came. When I had looked up at her, I had thought that she was the most beautiful thing I had ever seen.

And somehow here and now, even with all the awkwardness, I thought the exact same thing. And I could feel my trousers becoming tighter. Goddamn it, Luke.

Finally, she spoke. "I think the best thing to do is just to stay out of each other's way for a few days." She turned to face me, and my chest tightened. Why does she do this to me? I was rapidly losing my self-control. "I don't know if we'll ever be able to actually forget this ever happened, but we can at least --"

I leaned in and kissed her deeply. After a second of surprise, she folded and started kissing me back, and now that I was sober, I was a million times more aware of every spectacular sensation. Jesus, why does this feel so incredible?

It took a herculean effort to break the kiss before it progressed any further. I rested my forehead against hers. "Fuck... I'm sorry."

"Okay," she breathed. "That time was definitely you."

I groaned and pulled away, resting my head in my hands like she had earlier, as I tried to calm myself down.

Beside me, Charley coughed. "And you're sure you don't want to..."

"Yes." I dug my fingernail into my palm as hard as I could, trying to force myself to be smart about this. "I'm sure."

She took a few moments, steadying herself. "Good. Well... as I was saying before I was rudely interrupted, we won't forget but we can move on. We're not in love or anything, we just drunkenly slept together once. It's not a big deal if we don't want it to be."

I sighed. "Yeah. Cool."

"Right. Well, like I said, no contact for a little while." She fell silent, and we both sat there awkwardly for a few seconds, unsure of where to go from here. "Um... see you later, I guess."

She stood up, brushed herself off, and quickly walked out.

*****

So, we had both agreed to avoid each other for a bit -- stay out of each other's territory. The problem was, Charley's territory was not only pretty much the whole house, but also the entirety of London. And that meant more time cooped up in my room, which was starting to get a bit grating, even for me.

Being alone with my thoughts right now wasn't helping. Had I made the right decision when I told Charley we shouldn't ever do it again? Surely, yes -- us starting some secret, borderline incestuous love affair opened us up to a whole host of potential problems. But on the other hand, I'd had a crush on her my whole life, and as you can imagine recent events hadn't helped with my plan to move on from her. I kept thinking about how incredible that night had felt. Was I an idiot for giving up the opportunity to do that again?

Anyway, now I had plenty of time to go in circles trying to answer these questions in my head. And now that there was no Friday party on the horizon that would alleviate my incel behavior, my parents were starting to give me grief.

The Monday after my talk with Charley, my stepmum came knocking on my door.

She walked in, and immediately grimaced. "Ugh, it's a pig sty in here." She sniffed. "And it smells... ripe, to say the least."

"I appreciate the constructive criticism. I'll get on it real soon, I promise." I swung my chair to face her a flashed her a sarcastic smile.

"It's really not healthy to hole up in here constantly, Luke."

I sighed. "It's the holiday. It's not that deep." I wasn't about to let her in on the fact that the real reason I wasn't leaving my room was because I had drunkenly slept with her only daughter and was now avoiding her.

She muttered something under her breath and walked out, shaking her head. I had a feeling this wasn't over.

Sure enough, that weekend there was another knock on my door.

"Come in," I sighed, preparing myself for more nagging. But it wasn't my Mum or Dad that walked in. As soon as I saw the flash of blonde hair, I averted my eyes and looked up at the ceiling. "Uh... hello, Charley."

"Hey."

"Um... what can I do for you?" I coughed, wincing at how awkward I was being.

"Very formal," she remarked, one eyebrow raised. "I just came to see if you wanted to come to this party tonight. One of my old school friends is hosting."

"Oh." Weren't we supposed to be avoiding each other? "And... why exactly did you decide to invite me?"

She shrugged. "It's probably only going to be people from my year coming. You might know some of them, want to catch up."

Now that was far-fetched. She knew I'd only had six friends in school, and all of them were from my year's football team. "Mum told you to, didn't she?"

Charley looked away. Or at least it looked like she did, out of the corner of my eye. "You got me."

"Great. Well, you don't have to worry -- I'll tell her you begged me to go, but I told you to piss off and let me rot."

"No," she sighed. "You should come. We can't just avoid each other for the rest of our lives. It's time to push through and move on."

Why not? We've done it for the past four years, no problem. But I didn't say that. Truthfully, despite the fact that I hadn't sorted my feelings out yet, I wanted to go. If only to get my parents off my back.

"Okay," I said. "When are we leaving?"

"We're not going together. Unless you want to leave right now and spend two hours sitting around while we do our hair and makeup."

Two hours?? Luckily, I knew better than to comment on that absurd amount of time. "Alright, sure. So, when should I get there?"

"Around ten. I'll text you the address. And don't come empty handed, bring beer or something."

I rolled my eyes. "Thanks professor, I know house party etiquette. I'll see you then."

She gave me a small smile and left.

I sighed and rested my head in my hands. Are we really ready for this? We hadn't even looked each other in the eyes once during that whole conversation.

I took a deep breath. No. You got this Luke. I knew there would be alcohol. And I knew that Charley was so popular that she'd likely be flitting around all night, trying to find the time to greet a hundred people.

There was no pressure for this to be a massive turning point to put us back on track. Baby steps -- first, we needed to show we could spend an evening in the same area. Of course, in order to make it all go smoothly I was going to pre-game hard.

And so, five hours later I was standing in front of a pretty sizeable house in North London holding a six pack of Asahi, already pretty drunk.

A girl I didn't know opened the door and immediately gasped. "Oh my god, Charley. Your stepbrother's kind of cute."

Charley came up behind her and rolled her eyes. "Please don't be weird."

"I'm just saying, I never thought I was into younger guys, but..." The girl raised her eyebrow as she looked me up and down.

"Awful," Charley sighed. She shot me an apologetic look, but we ended up eyeing each other for a moment too long and both had to avert our gaze awkwardly. Clearly, I didn't pre enough.

"Sorry Luke, just messing with Charley." the girl laughed. "I'm Abigail. You remember me from school, right?"

Obviously I didn't, but I smiled and nodded anyway. "Yeah. Nice to see you again."

"Well, come on in." I followed them both inside, while Abigail gave me a quick tour. "Kitchen -- you can get a drink in there. Everyone's in the living room, There's one toilet down here, and the stairs here lead to the bedrooms and another toilet." She pointed at each of them in turn. "I'm hoping at your age, you won't find anyone to use any of the bedrooms with tonight."

"I'm twenty," I laughed.

"Aww. Just a baby," she giggled. Charley didn't care to comment on that apparently and was checking something on her phone.

Abigail quickly glanced at her to confirm she wasn't paying attention and leaned in close. "I wasn't joking about the cute part though," she whispered.

Apparently, she hadn't been as sneaky as she'd thought, because now Charley turned around and stepped between us. "Right -- that's enough. Abigail, go call your parents or something and reevaluate your life."

Abigail laughed and held her hands up, winking at me as she walked off. "He's all yours."

Charley turned away, but not before I saw her blushing slightly at Abigail's last comment. I couldn't blame her, given recent events. "Luke, come grab a drink and I'll introduce you to some of my more... respectable friends."

Once we made it to the kitchen, she sighed as she poured me a vodka lemonade and topped off her own drink. "Thanks for coming. I think it'll be good for us."

I smiled at her, doing my best to hide my doubt. "Yeah. I think so too."

She looked up and smiled back at me, and in that moment, I appreciated the two hours she and her friends had spent getting ready.

She looked incredible. She'd curled her shoulder length blonde hair, and it framed her face perfectly. Her cheeks were tinted red, though from alcohol or makeup I couldn't tell, and her lips were a deep shade of scarlet. Her black eyeshadow framed her almond shaped, light brown eyes. Smoky hot yet somehow still classy -- just like her to pull some shit like that off.

Luckily, I didn't have time to form any inappropriate thoughts about my stepsister. Drinks now made, Charley took me by the arm and led me into the living room, where a crowd of people had already amassed. We walked up to a group of five or six people standing near the fireplace.

"Hey everyone," Charley announced as we joined them. "This is my little brother, Luke."

One of the guys, good-looking with frizzy brown hair, smiled at me. "Oh shit, the stepbrother, right? I'm James. I was on the football team in school, Charley said you were too. Yeah, we heard about you guys three years below, you were pretty good."

I nodded. "Nice to meet you. Yeah, we weren't so bad. But you guys went undefeated in your last season, no?

He shrugged, feigning modesty. "Eh, what can I say? We did alright for ourselves."

"If only you could have replicated that in your A-levels," Charley commented.

James laughed. "Uncalled for, man."

The other people around the circle introduced themselves. All nice enough, but very much people I would never have met or talked to in my time at school.

Just then, the doorbell rang. "Oh. that's probably Eloise, I should go say hi," Charley said. She shot me an apologetic glance and rushed off to greet another member of her legion of friends.

James draped an arm around my shoulder. "Guessing you don't really know anyone here?"

I laughed nervously. "Yeah, not so much."

"No worries man, we'll look after you. Can't imagine it's easy being Charley's younger brother."

I shook my head. "Oh, you don't know the half of it."

The next few hours were pretty much standard house party stuff -- a whole bunch of introductions to people whose names you'll forget a minute later, followed by meaningless small talk, made bearable only with copious amounts of alcohol.

I hung out with James and his friends for a bit, only to find them dispersed after I came back from the kitchen after refilling my drink. I kind of floated around the living room, talking to anyone who I may have recognized, my voice getting hoarse from trying to tell people my university degree time and time again over the blasting music. After a while, I met up with James again and he introduced me to a couple other people from his football team.

As I had expected, I didn't catch Charley much as she roamed between rooms, completing her quest to have a full conversation with every single one of Abigail's guests.

By 1am, the party was still going strong, but I certainly wasn't. James was working the next day, so he'd left. And I had drunk an amount that was verging on way too much.

I took a few minutes and sat down on one of the armchairs in the living room, resolving to people watch for a while until I sobered up a bit. But I quickly realized that I wasn't just passively looking. I was seeking someone out.

Charley was sitting at the table by the window, talking with two other girls I hadn't been introduced to.

As I watched her, I realized I wasn't even creepily picturing the night we'd spent together after Mum's party anymore. Instead, I was creepily imagining how she'd react if I went up to her right now and told her I'd changed my mind.

Would she smile and tell me she felt the same way? Would she kiss me like she did last Friday? Would she lead me upstairs to one of those bedrooms Abigail had showed us?

Yeah, I had a problem.

So much for sobering up. I got up and strode over to the kitchen, ready to make myself a vodka coke that was way more vodka than coke. I had just filled my glass halfway with vodka when I heard someone come up behind me.

"That's... an ambitious drink," Charley said, as I spun around to see her.

I scratched my head, trying to think of an excuse. I couldn't exactly say that I was drowning my sorrows and trying to get her off my mind. "I'm an ambitious guy."

"Well take it easy, buster. I'll hold your hair back while you throw up if I have to, but I'd really rather not."

I laughed, despite myself. "My hero."

Charley rolled her eyes, but she smiled as well.

I was surprised, as always, at how easy it was to talk to her like there was nothing going on. But try as I might, I wasn't able to stop my thoughts from wandering again. The last time we were both drunk, I'd had the most amazing yet complicated night of my life. Did this night have something in store as well?

"You enjoying yourself?" Charley asked.

"Yeah, I think so. It's helped take my mind off of everything," I lied.

"Hmm," she replied, looking me right in the eye. "That's good, then."

Fuck, she can see right through me. Taking my mind off of everything? What a joke. Even standing here just talking to her, I was getting turned on again. Oh, man. Was I really just that into her?

It didn't help that I just couldn't stop staring at her face. Why did she have to look so good right now? It was really inconsiderate of her. Especially while I was dealing with all this emotional turmoil.

Unfortunately, I clearly wasn't being very subtle about it.

"Umm... why are you looking at me like that?" she asked.

I ignored her question. It was now or never. Was I really going to go down this path? I just needed a moment more to myself, a moment to think....

But then I stopped myself. I'd spent twelve years overthinking and obsessing. Fuck feeling guilty. I'm not going to do it anymore. I steeled myself. Here goes.

"Do you still want to have sex again?"

"What?" She clearly hadn't been expecting that, and she blushed. "I never said that I wanted..." She paused and looked up into my eyes. "Why are you asking?"

"Why?" I could feel my heartbeat in my head, equal parts nervous and unbelievably turned on. "Because if so, I'm in. That's why."

She stared at me, wide-eyed. "Are you serious?"

"Do I look serious?"

The music from the speakers and drunk people singing in the next room felt like it was worming its way into my brain, as she stood there and took me in. Slowly, the corners of her mouth crept upwards into a smirk.

"You look drunk, Luke. But..." She paused, and bit her lip. "Holy shit. Okay. We can go home. I'll grab my coat."

She started towards the front door, but I grabbed her arm. "No. I can't wait that long."

"Are you..." She didn't bother asking me whether I was serious again. "Fuck." She glanced nervously towards the entryway back to the living room. "Okay. Shit, okay. Let's go upstairs."

I followed her as she quickly made her way up the stairs. I was about to dive into one of the bedrooms, when she pulled me back.

"Are you crazy?" she whispered. "They don't have locks."

"So?"

"So??" she repeated like I was an idiot, which was probably fair. "I am not risking someone here finding out about this anymore than I have to. If you're just so horny you can't wait, we're doing it in here." She gestured towards the bathroom.

I shrugged. In that moment I really didn't give a shit.

I gently pushed her inside the bathroom, then turned and locked the door. And then I grabbed her face and kissed her hard. Not wasting any time, I plunged my tongue into her mouth, and she moaned softly as her own tongue responded in kind.

Finally, she came up for air. "Shit, what's gotten into you?"

"You are so, so fucking hot," I replied.

She grinned. "You just realized?"

"Ugh, shush." I kissed her again to shut her up and maneuvered us over to the bathroom counter. Breaking off the kiss, I picked her up and set her on the marble surface, before grabbing at the hem of her jeans and pulling them all the way down, along with her panties.

Looking at her trimmed, pink pussy for the first time in a week, I suddenly got the urge to try something new.

I slowly got down on my knees, looking at it up close. Maybe it was a bit ambitious to do this for the first time so early on, but I was drunk and horny and I really, really wanted to taste her. Besides, like I said earlier, I'm an ambitious guy.

"Wait, you don't have to," Charley suddenly said from above me.

I looked back up at her, a little embarrassed at my own assumption. "Oh. You don't want me to?"

"That's not what I'm saying. But I can tell you're pretty horny, and-"

"No, just... shut up for a sec," I interrupted. "I want to." What a gentleman.

She smirked. "Shutting up."

Here I go. I set the tip of my tongue at the bottom of her pussy and slowly licked up, all the way to her clit, before kissing it.

I repeated it a few times, licking around her lips and using my fingers to spread them, and going in further to her entrance -- not inside, but damn sure everywhere around it.

Above me, Charley groaned. "Ugh... stop teasing."

Honestly, I hadn't even known that what I was doing was just teasing. But I knew how I could ramp it up.

Taking a deep breath, I leaned forward and pushed my tongue all the way into her snatch. Charley gasped, and instinctively grabbed my head with both hands, fingers running through my hair. I took that as encouragement.

I reached up with my started circling her clit with my fingers as I tongue-fucked her beautiful pussy. It was kind of trippy, experiencing the bumps and ridges of her snatch in a completely different way to our encounter last week.

I had actually been a little worried going into this, because some of my friends had told me about bad experiences with how girls tasted. But apparently Charley had been eating enough pineapple or whatever, because I couldn't get enough.

Switching it up, I pulled my tongue out and shoved three fingers in, causing her to groan loudly again, while I began to focus my attention on her clit, lapping at it furiously with my mouth organ.

"Oh god... you're gonna make... gonna make me cum," she gasped above me. Like that was news to me -- I could feel her twitching on my fingers I as I fucked her with them, and I wasn't far off of full on gulping down her juices with how wet she was getting.

"Luke... I'm coming, I'm coming," she hissed in pleasure. I geared up for the final stretch, curling my fingers and going to town on her clit and g-spot. "Fuck!"

Finally, I felt her clamp down on my fingers, as she yelped and released a rush of pussy juice all over my hand, which I lapped up greedily.

After, I was a little wobbly as I got up from being on my knees for the past few minutes, but I was still in a lot better shape than Charley. I looked down at her as she sat there on the counter breathing heavily, eyes half closed. I sent a silent thank you to all the pornos I'd ever watched for teaching me how to eat a girl out.

But we weren't even close to being done. I gently helped her off the counter and turned her around, laying her hands on both sides of the sink, so that her ass was sticking out towards me. Just looking at her like that, my cock sprang to full attention.

Charley must have figured out what I was doing, because for the first time since her orgasm she spoke up, still breathy. "Go gentle... okay? I'm... still sensitive."

"Sorry Charley," I muttered, lining up my dick at her sopping wet opening. "I don't think I can promise that."

With that, I pushed forwards, and Charley grunted as I sunk all the way inside her. I grabbed her waist with both hands and started thrusting in and out of her. Her buttcheeks rippled every time my hips collided with them and I bottomed out inside her, the clapping sound almost hypnotizing.

"Ugh... fine," she moaned, before mewling at one particularly hard thrust. "Do... what you... want."

With her permission, I picked up the intensity. Her pussy, having been already wet from before, was getting even more sloppy, squelching obscenely every time I sawed in and out of her.

I looked up from where we were joined, and I saw that her face was only a few inches from the mirror edging dangerously close every time I thrust forward, her hot breath steaming on the face of the glass. It was the hottest thing I'd ever seen in my life.

"Oh fuck," she panted. "Go slower... I'm... gonna get too loud."

I had absolutely no intention of going slower, and I instead responded by picking up the pace even further. In that moment I was so turned on that I couldn't have given less of a shit about someone overhearing or finding out about us. The King of England could have walked into the bathroom, and I wouldn't have stopped.

I leaned forwards slightly so I could cup her breasts through her shirt, getting even deeper inside her, and it wasn't long before I could feel my orgasm approaching.

"Agh... Charley," I grunted. "I'm gonna cum... soon."

She didn't respond, instead just whimpering slightly every time my cock reached her womb, but she reached down and began furiously rubbing her clit. As she tightened up, I knew she had gotten the message.

Finally, Charley cried out and stiffened up, her pussy convulsing and clamping down on my dick. I responded in kind, driving my cock deep inside and shooting out every ounce of seed I could muster as her inner walls continued to milk me.

When I was spent, I slowly pulled out of her, watching the strands of our combined juices that were connected to the head of my penis breaking off one by one, before stumbling over to sit on the toilet seat and catch my breath.

Charley turned around and grabbed a paper towel, before gently wiping off her red, thoroughly worn-out pussy. Shakily, she pulled her jeans back up and climbed up to sit on the counter again, and we both sat in silence for a few minutes as we recovered.

Charley was the one to break the silence. "So," she began. "You gonna sober up tomorrow and realize this was all a huge mistake?"

I shrugged. "Honestly, I still think it might be right now. But no, I won't. I don't really give a shit anymore."

"Fair enough. We can work with that."

I wiped the thick coating of girl cum off of my cock with some toilet roll and stuffed it back into my underwear. I could feel Charley's eyes on me, something on her mind, and I tried to smooth out my clothes as I waited for her to spit it out.

"What made you change your mind?"

I looked at her, putting a serious look on my face. "Honestly?"

"Yeah." She straightened up, meeting my gaze.

"Well..." I took a deep breath. "It was what you said that morning, when you said it would fit into your plan. I thought about it, and I saw that as long as we were adhering to your divine commandments everything would be alright."

She threw a toothbrush at me, and I held my arm up to block it as I cackled. "Asshole," she muttered. "You joke, but you're actually not wrong. And believe me, in the morning we're setting some ground rules."

"Naturally," I sniggered.

"And don't for a second think I don't know what the real reason is," she continued. "You think I didn't notice you checking me out downstairs? You just couldn't help yourself, could you?"

"Lot of attitude for someone I had steaming up the mirror a few minutes ago," I scoffed.

She glared at me, blushing hard. "Just come and check the hallway, you little shit. We need to get moving."

I chuckled and went over to poke my head out the door. "All clear."

"Okay." She pushed past me, and we walked back to the stairs. "Let's just hope no one noticed we were gone."

The next day, true to her word, Charley came into my room to lay down some ground rules. It felt odd given that she'd been the one to suggest this being a thing in the first place, but Charley liked rules. She always had. And besides, after last night I was pretty much good with anything.

"First things first," she began, "caution is the number one priority. No one can ever find out, especially Mum and Dad. And that means that nothing is going to happen during the day while they're at home. If we do anything, it's going to be at night while they're asleep, quiet as possible, but ideally while they're out. Sound good?"

"Sounds good," I replied.

"Okay. Secondly, when this thing ends, and it will end, we both agree there'll be no hard feelings."

"Our secret sibling affair isn't until death do us part?" I put my hand over my heart. "Ouch."

She frowned, not amused. "I'm serious, Luke. I know I said that this wouldn't affect my plan, but that's only if it stays a short fling. This can't stretch out to the extent that it'll affect either of us meeting someone, getting married, having kids. Having a family. You get that, right?"

It was a bit of a bummer to put an expiry date on this so early on, but it made sense. "Yes ma'am."

"Good. Finally, we should discuss the circumstances around which it might end. Honestly, we'll hopefully just get it out of our system fairly quickly. I mean, this only started because of some chance encounters and how sex-starved we both were before that."

"Uh-huh." Sex-starved was one way of putting it.

"Failing that, you're flying to Tokyo in September. A year apart would almost certainly mean this will fizzle out. And anyway, you'll be in a foreign country, I'll have started working, and we'll be meeting a lot of new people.

"Which brings me to my next point," she continued. "This doesn't stop us from meeting people, going on dates. And of course, if there's ever the possibility that a relationship with someone else could get serious, this ends."

Yeah, I wasn't sure how well that was going to go for me. I'd struggled to go after people not named Charlotte Kim even before this had all gone down. But I nodded anyway.

"Alright, good." She got up from my bed.

"Hang on," I said. All the discussion about our relationship had got me a bit riled up. "Do you maybe wanna..."

"God, you're insatiable," she laughed. "No, not right now. I'm about to go out."

"Fine," I grumbled.

She shook her head, chuckling, and made her way to my door. But she stopped just before she left.

"Luke, there's one more thing we should put out there, you know. Just to be thorough."

"Well, I'm all about being thorough."

"I'm not saying that this is likely, or even possible. But if at any point either one of us feels like this progressing past something that's not just physical anymore... it ends, immediately. That's non-negotiable, no matter which way it goes."

"Yeah, of course. I get it." That was one point I wasn't going to try and contest. I knew all too well the risks of going in too deep -- it was why I'd distanced myself from Charley in the first place, all those years ago. And I wasn't worried, anyway. I had always known what my feelings were: a crush, pure physical attraction. I loved her, yeah -- but as family, not romantically.

Still... now that it was actually out there, the idea of it made me feel a little strange. Charley and I in love? I shivered. Best not to dwell on that.

"Good. See you later," she smiled, and shut the door on her way out.

I sighed as I flopped onto my back. My first ever exposure to a Charley planning session, and it was pretty mentally taxing, even though I hadn't disagreed with anything she'd said. Was this just how her brain worked, every single day? Trying to fit everything in her life within the rules she'd set for herself? It all seemed a bit much.

I turned to the side and saw the monitor on my desk. Okay, Luke. You've occupied your mind with you and your stepsister's relationship enough over the past 24 hours. Now, your PlayStation is calling your name.

*****

After a long day of gaming, I stood in the shower later that evening, eyes closed as I basked in the hot water.

I felt better than I had in while; definitely the best I had since Charley had come back from the US, and honestly maybe even since before that. I'd stayed in my room all day (Let's not get overly excited, I hadn't won the lottery), but I'd cleaned it up, aired it out and borrowed a couple scented reed diffuser sticks from my stepmum to make it smell nice.

The reason was pretty obvious. Unfortunately, just as I was thinking about it, the reason came bursting into the bathroom unannounced.

"Charley!" I exclaimed. "It's occupied!"

"Really, dude? After everything? There's literally nothing here I haven't seen before." She started to look me up and down, so I quickly covered my dick with my hands.

"That's not the point," I hissed.

Charley sighed and turned to the sink. "Enlighten me, Luke. What's the point?"

I looked away, embarrassed. "My willy gets really small in the shower," I said quietly.

"You are so British," she laughed. "My willy. Sound like you're in a Mr. Bean sketch."

"Fine, let me star-spangled-bannerize it for you," I scoffed. I carried on in my best American accent. "Dude, my cock gets totally small and shit when I'm in the shower."

Charley glared at me. "That is not what I sound like."

"I hate to break it to you, but that was a one-to-one rendition of your voice."

"Whatever," she huffed, turning back to carry on brushing her teeth.

The conversation over now that she was busy, I leaned my head against the glass shower wall and peered out. She was wearing just an oversized t-shirt that fell below her hips and, I assumed, panties underneath that. I stared in awe at her unblemished, toned legs, following them all the way down to her pedicured feet. Looking up, I saw that she had also removed all her makeup, but she still looked unfairly hot. As she spat out her toothpaste, I started to feel my slightly wrinkly penis start to stir. She couldn't pull the 'busy' card this time, right?

"So... you wanna join me?" I asked, in my best suggestive voice.

She turned to face me, eyebrow raised. "Real smooth, Luke. And no, Mum and Dad are still awake downstairs, it's too risky."

"Nah, they're still watching a film, right? They won't be able to hear over that and the shower. It's fine."

Charley went silent as she considered it for a few seconds. "We're supposed to be more careful than this," she said. But then she shrugged. "But okay, sure. Just this once."

I frowned as she took off her T-shirt and panties dispassionately and stepped into the shower with me. "You could at least pretend to be enthusiastic about it."

"Oh yeah?" She stepped up to me slowly, shooting me a sultry smile. When she spoke, her voice was low and whispery. "What would you prefer, huh? That I tell you just how turned on I've been all day, counting down the hours until I could come home, and you could fuck the shit out of me?"

She didn't give me a chance to answer, putting a hand around the back of my head and pulling me down into a kiss. I let out a little moan involuntarily as she slowly worked her tongue into my mouth, letting me taste the minty toothpaste she'd just been using.

When she pulled away, I blinked a few times and cleared my throat. "I know you're making fun of me, but that was really hot."

"Hmm, affected you much?" she replied, looking down at my erect penis. "Your 'willy' isn't looking so small anymore. And you know, maybe I should pay you back for last night."

"Pay me back?" I asked, confused.

At least, I was confused until she started kissing her way down my chest, all the way to my waist. "Oh fuck, Charley."

Finally on her knees, she blew on my cock gently and smirked up at me. "Any objections?"

"God, no."

"Yeah, that seems about right."

Not wasting any time, Charley grabbed my cock in one hand and held it up, licking all the way from the base to the tip, and sending a shiver down my spine.

She continued licking around my mushroom head for a few seconds, before leaning forward and enveloping my cock fully with her mouth, almost to the base.

I had to stifle a yelp. The sensation was almost overwhelming -- I could feel her soft, wet tongue sliding around on the underside of my shaft, and as she slowly pulled back, she began to bob back and forth, taking me all the way to the entrance of her throat.

I'd never really been that interested in getting head, after horror stories from my friends involving teeth or gag reflexes. Even without that, most people I knew agreed that blowjobs just weren't as good as the real thing.

But here, with what I was experiencing right now, I couldn't have disagreed more. Charley was slobbering on my cock how I imagined a pro must do it, her tongue twirling around the head of my penis and gently probing my slit.

'Oh... Jesus. That feels so fucking good," I groaned. I didn't think I was that far off cumming, and she'd only been doing it for about a minute.

Spurred on by my words, Charley picked up the pace, her tongue lathering my cock with her saliva. She moaned softly as she went to town, and the vibrations around the head of my cock almost put me over the edge.

"Ngh... shit," I grunted. I was on the verge now, doing everything in my power to hold back, but my dick had other ideas. I was going to cum in seconds.

Luckily, she must have felt my wood twitch in her mouth because she suddenly pulled off with a wet 'pop', making me gasp. "Nuh-uh," she said, wiping her mouth with the back of her hand. "You still need to fuck me."

"Holy shit," I panted, struggling from the exertion of holding back my orgasm. "I'm guessing that wasn't your first time doing that."

Charley raised an eyebrow as she stood up. "Are you calling me a slut, Luke?"

"No! I... uh..." I stammered, no idea how to dig myself out of this hole.

"Because if I am a slut," she continued, apparently unbothered, "maybe you should do me like one." She put both her hands on the wall and bent over with her beautiful ass pointed back at me.

I did not need to be told twice. I lined up my cock at her pussy entrance and slowly slid into her with no resistance. I don't know whether it was the generous coating of saliva already on my dick, or whether she really had been turned on all day like she'd said, but within seconds she felt ridiculously wet.

I stared down at her tight, pink, glistening wet pussy as it enveloped my cock over and over and over. I couldn't believe that this was the third time I was fucking my stepsister. I would never, ever take this for granted.

I ran my hands up and down her waist as I ploughed into her from behind, getting lost in the moment. Speeding up, my hips began colliding hard with the back of her ass and thighs, the loud clapping echoing around the tiled shower.

"Hey!" Charley looked back over her shoulder to glare at me, though the effect of her death stare was lessened slightly when I saw how red-faced she was from the sex. "Be careful... ugh... they're just downstairs!"

'Uh-huh..." I slowed down my thrusts slightly, but I snaked my hand down to her clit and began rubbing her inflamed clit as I continued to saw in and out of her tight snatch.

"Oh... you asshole," she moaned. "Fuck... don't... stop."

After a few minutes, I could feel myself on the verge of cumming. Honestly, I was surprised I'd lasted this long at all, after the blowjob. It didn't help that ever since I'd started touching her clit, Charley had been clamping down on my shaft like a vice.

"Charley... ugh... gonna cum."

She opened her mouth to respond, but it just came out as a yelp. Biting her lip to stifle her moans, her voice finally came out as a low groan, barely audible over the running water and the soft clap of my hips against her cheeks.

"Fine... just go... ahead."

A second later, I grunted as I pushed all the way in and coated her insides with thick ropes of my cum. Clearly feeling it, Charley shuddered, her pussy juices gushing out as I continued to masturbate her and she came alongside me.

Once I pulled out, I watched, mesmerized, as my thick cum spilled out and ran down her leg, before swirling around in the shower water and disappearing down the drain.

I took a step back and leaned against the other side of the shower, resting my head against the cool tiles. It blew my mind that it was only yesterday that we'd been at the party together. Is this just my life now?

"So... are we gonna be doing this every day?" I asked.

Charley turned to face me, laughing. "No. I have other shit to do. Besides, Mum is home fairly often, and I'd really rather not take risks like this where possible. I'll come to you if I'm not busy."

I paused. "You'll come to me? Do I just not get a say in what we do?"

"Well, you can always say no if you don't want to," she snickered. "But I don't see that happening, do you?"

I glared at her, not about to give her the satisfaction of agreeing with her.

"So, you're cool with that, right?" she continued.

Normally I would have pushed back against her bossing me around like that, but I was still coming down from the high of my orgasm. And honestly, she was right. Charley sporadically coming to me for sex wasn't something I was about to say no to. "Yeah," I grumbled.

She smiled at me sweetly as she stepped out the shower. "Good boy."
