My Stepsister's Piss-Soaked Panties

*All characters are fictional and are at/over the age of 18.*

"Shall we pick up where we left off last week? It's the autumn of your eighteenth year, and you have just lost your virginity to your stepmother Angie..."

"Okay. Well... things actually get pretty great after that. Angie starts treating my dad a lot better. Probably she's just doing it out of guilt, but it really has an effect on him. He ends up recovering from his surgery way earlier than expected, and he's back at work after just a couple more weeks. I'm doing well in college, getting decent grades, and my team wins its first couple games of the year. Angie even gets a big promotion at her job."

"But what happened between you and Angie... does this continue?"

"Yeah. We pick it up pretty much every chance we get. I think we both just figure we already crossed the line, so we might as well see how far we can take it, right? Instead of like, trying to pretend it never happened. She starts coming into my room late at night when Dad's asleep. You know, I'd thought it couldn't get any better than what we did in the shower, but I had no idea what she'd be like in bed.

That first night though, she just about scares the hell out of me. I wake up maybe around one or two in the morning with that anxious feeling of being watched when you don't know where from, and as soon as I'm aware enough to make out the shapes of things I see her sitting in my chair about five feet away, just watching me, and she's completely naked.

By now we're past the point of bothering with excuses. She tells me straight away that she wants to show me the ropes, teach me how to really please a woman. Of course I want to learn all that as much as any eighteen-year-old guy. So I let her show me how to give head the way she likes it, rubbing the whole front of my tongue over her clit again and again and pushing on it from behind with my fingers inside her. She makes me do it real slow at first; says it'll feel better if I tease her until she can hardly stand it. I do it slow like that and after a while she starts squeezing herself around my fingers and kinda rocking her pussy into my face, which I guess is her trigger to go faster.

We get into a sort of rhythm, with me giving it to her harder and faster the harder she gives it to me, until suddenly she pushes me away and races over to my closet. She comes back with three thick towels that she puts down over my bedsheets to sit on before she lets me keep going.

After what I told you last week you can probably imagine why. A few minutes after I start up again I feel this pressure building up against the tips of my fingers. She tells me to stick them in deeper, and as soon as I do I feel warmth flowing all around them. A moment later I can taste it too. She's leaking into the towels. She's got my blanket stuffed over her mouth to keep from moaning but I can feel her body spasm and shake. It's so strange, we're both screaming inside but the room is dead quiet apart from the hum of the fan and the little hissing sounds as she lets out spurt after spurt. Her shaking gets worse until finally her whole body tenses up and her pussy pinches on my fingers like a vice and she just floods the towels completely. Then she whispers at me to get up and fuck her and I do; I grab her legs while they're still all slippery and hot with her piss and--"

"Stop here a moment, please. I'm sorry, but last week you told me of feeling disgust at the sight of your stepmother's urination, yet here you seem to find it arousing, is this so?"

"I... I can't exactly explain what happened. Something clicked in my brain I guess, and I started seeing it different. By that point piss just seemed so obviously like part of sex that I didn't know how I ever thought it wasn't."

"Similarly, perhaps, to how the woman you had for so long seen only as a mother now appeared to you in, shall we say, the fullness of her femininity?"

"Maybe. I mean, it's not like I could really stop seeing Angie as a mother. Part of me can only ever see her like that, and it still hates the rest of me for what I did. But there's another part of me that had wanted to do it for a really long time and used to hate the rest of me for holding back."

"Some believe every mind to host a variety of selves which can harmonize or contend like players in an orchestra. But perhaps we should save such abstractions for later."

"Well, my orchestra's gotta sound like a fuckin' catfight these days. Anyways... Angie starts coming by like that every night. Dad's a heavy sleeper, and as far as I know he never notices her missing. Never notices all the extra laundry she's doing, either. It's better when we get a chance during the daytime though, when he and Riley are gone and we can be as loud as we want. So like I said, things are great right around then, and it goes on that way until around the end of the year. That's when Audrey comes back."

"Audrey being your stepmother's daughter from her first marriage, yes?"

"Right. She's my age but she's a lot smarter than me, so instead of going to the local college like I did she went to some big university in the city. But I guess she couldn't handle it, because around the end of her first semester she dropped out. Her dad had sold his house when she'd moved out in August, and for whatever reason he couldn't take her in at his new place, so she came to stay with us.

Problem was, there were only three bedrooms in the house, and Audrey and Riley never got along with one another. I mean, it was kinda obvious that them sharing a room would be a nightmare for everyone. So... Audrey ended up rooming with me."

"Two teenagers of opposite genders sharing a bedroom... your parents must have considered you both quite mature or quite immature for your ages."

"Look, I know it's weird, but like I said, the whole thing was unexpected and my parents were desperate. And I think they figured the two of us being like, brother and sister made it okay. To be fair, we'd been calling each other that since we were both nine. We'd actually shared a room for a while back then too, though she did live more of her time with her dad. A lot more, especially when she got older and she and Angie started fighting constantly. By our junior year I hardly even saw Audrey outside of school."

"A second marriage often places a great strain on an existing parent-child relationship."

"I don't know. I remember them being really close when we were young, definitely in those first few years after Angie married my dad. They did everything together. But maybe that's the whole reason Audrey took the whole teenage rebellion thing so far."

"That too is a familiar drama."

"Well, drama's the word for it. They would get into these blowout shouting matches, sometimes even in public. The thing was -- look, I told you that Audrey's always been really smart, but around high school she started acting like she just didn't give a shit about her grades or anything else. She started hanging out with these kids who would smoke weed in the parking lot and set stuff on fire for fun. She stole money out of Angie's purse. My parents had to start keeping their liquor bottles locked up in their room. And I couldn't even tell you how many times Angie told her she wasn't leaving the house wearing what she was wearing. It got to where Angie would go through her clothes when Audrey was away and just throw out whatever she didn't like."

"How did this conflict affect you at the time?"

"I just tried to stay out of it. Dad too. They both gave up trying to get him and me to take sides pretty early on. And honestly, I don't know whose I would have picked if I'd had to. They were both so spiteful with each other."

"I see. I take it then that your stepsister's return bode ill for the happiness which had so lately come to your household?"

"It really did. I gotta say though, this time it was definitely Angie driving it. She starts laying into Audrey right off, calling her a failure for dropping out and a burden on her and my dad for staying with us. But surprisingly, Audrey doesn't even fight back. She just takes it. I don't know what happened at university, but it seems like it changed her.

Anyways, with Audrey sharing my room and not having a job or school or anywhere to go, my chances to be alone with Angie basically disappear. She can't sneak in to see me at night or join me in the shower anymore. I think that makes her temper even worse, on top of having Audrey back in the house. After a little while it isn't just Audrey she's taking it out on, either. She starts snapping at my dad and me over any little thing that bothers her."

"And meanwhile, how are you adjusting to your stepsister's presence?"

"Well, of course I'm not too happy about having to give up half my room, but it turns out not to be as bad as I'd thought. Audrey mostly just keeps to herself and tries not to bother me at first. She blames herself for the whole situation, and probably takes it to heart when Angie calls her a burden, so she tries to be as small and quiet as possible.

And you know, I feel bad for her. Maybe when you live that close with someone, week after week, it's just hard not to sympathize. Anyways, Audrey and I get to talking with each other, usually at night before bed. The conversations get longer and weirdly, even with Angie's craziness and my fear of her telling our secret and Audrey's depression, when it's just the two of us talking it starts to feel just like it did when we were younger, back when Angie or my dad had to come check on us every five minutes after lights-out to make sure we weren't keeping each other awake."

"The pressures of adult life often help us find new appreciation for such familiar comforts."

"For me, yeah. Angie sure doesn't seem to be getting any familiar comfort from her daughter, though. When she sees us talking or joking around she takes it like a slap in the face. It works her up so bad I'm scared she's gonna let slip to Audrey or even Dad about what happened between us just to spite me. By the end of January, Audrey and I are both walking on eggshells when she's around. Then, around that time, something else happens.

I wake up one night with the same feeling I'd get with Angie watching me sleep. But Angie's not there. I don't get up for fear of waking Audrey, but I'm spooked enough to look around the room for anything out of place. I'm about to go back to sleep when something catches my eye, something moving in the darkness. I keep staring at the spot where I saw it, with my head on my pillow and my eyes barely open, until after a while my eyes adjust and I can make out what it is.

The shape I've been staring at is Audrey's body under her blankets. The blanket is shifting a little up and down, over and over, right about where her waist would be. Her eyes are closed and she looks asleep, but she isn't snoring at all. I keep still as a stone, hardly breathing. After a time the motion gets a little faster. Then I hear a noise, this tiny little whine. I doubt it would have woken me if I wasn't already up, and if I hadn't been watching Audrey I might have taken it for one of the cats mewing downstairs. But a moment after I hear it, the blanket stills. And a few minutes after that, I hear her soft snoring begin."

"You believe you had witnessed your stepsister pleasuring herself?"

"I know I did. She told me so herself later on, after everything went down. She said that hadn't been the first time either."

"And how did you feel about this?"

"Honestly, I felt a lot of fucking things I didn't wanna be feeling. I mean, everything was falling apart with Angie; I was losing the love of my own stepmother just for not being able to fuck her, which wasn't even my fault; but at the same time I knew it was my fault for getting into it with her to begin with. And it wasn't like the end of that didn't leave me pent up too... I jerked off in the shower every day imagining it was her warm piss running down my body instead of water, and even that wasn't enough to keep my head straight. Knowing what Audrey was doing drove me fucking crazy, but I didn't want to risk losing the sister I'd just gotten back."

"That's certainly a situation I wouldn't wish upon any young man. It's unfortunate that lust so often struggles against every other means of our happiness."

"Yeah, well, the struggle didn't go on for long. And you can probably already guess which side won."

"I'm afraid that I can, but do go on."

"Okay. So in February my team is scheduled for an away game against this other college upstate, about five hours' drive from our town. Usually we charter a bus to take us to games that far away, but there's some last-minute complication with the bus company and we end up finding out the day before that we're all gonna be responsible for our own transportation. I don't have a license at the time. I know I can hitch a ride with one of my teammates, but as soon as I mention the situation to my parents over dinner that evening, Angie insists on driving me herself.

I see the look in her eye and catch on immediately to what she's thinking. I can practically watch the fantasies already playing out in her head. But a second later they're all smashed to bits when Audrey says that she wants to come too.

Well, Angie hadn't anticipated that. She's furious; it's obvious that she wants to object, but Dad's right there next to her and she can't think of anything to say that won't raise suspicion. I can't either, and honestly, I'm not even sure if I want to. I don't wanna show it in front of Angie, but it actually makes me feel really good that Audrey's willing to drive so far just to see me play. Not that she has anything better to do, I guess; but still, it means a lot to me, and I know that refusing her would really hurt her feelings."

"Might it have been that you feared rekindling the entanglement with your stepmother for reasons beyond your affection for Audrey?"

"I don't know. Maybe the past month had given me enough distance to see how insane that whole thing was. But I know that if Angie and I had gone alone, I wouldn't have been able to hold back."

"I see. Continue."

"So... the three of us make the drive together. It would have been better if my dad had come too, or even Riley, but Dad's job's got him on some big project in the city that week, and they're behind schedule so his crew's working dawn to dusk and staying in a hotel out there until it's done. And I doubt Riley would have come even if she hadn't been over at some friend's birthday sleepover that day.

The way there is exactly as awkward as you'd expect. Neither of them talk much to each other, so I end up having to juggle two off-and-on road trip conversations at once. There's tension right from the beginning, and it only gets worse until I just turn my music up loud and tune out everything else to psych myself up for the game.

I won't bore you with a play-by-play, but my team ends up losing badly. It's our worst game by far. We all have a sad little dinner afterwards at a restaurant nearby, then we're back on the road. The sun's already setting by the time we get on the interstate, and soon everything's dark outside. Audrey and Angie are as tired and irritable as I am after spending their whole day together, so we all keep pretty quiet. I don't think anyone says a word for the first hour or so... until Audrey breaks the silence by announcing quietly that she needs to use the bathroom.

Angie doesn't say anything. Audrey's sitting in the back, and I guess she thought her mom didn't hear because she repeats it a little louder, and this time Angie just snaps at her that she should've gone back at the restaurant.

Silence comes again after that. I'm not really sure if Angie's reply meant she would pull over for Audrey or not. After another fifteen or twenty minutes though, I think I know the answer. I glance back at Audrey and she's pleading with her eyes for me to help. So I ask Angie if she can get off the highway and look for a gas station or something.

When Angie looks over at me I can see the same anger that had been flashing in her face every time she saw Audrey and me talking together, and she says 'no, I'm not going to make this trip any longer than it needs to be just because my daughter didn't take care of her needs when she had the chance. She can hold it like the rest of us.'

The way she says 'the rest of us' makes it clear enough that Angie's been holding it too. Maybe even longer than Audrey. I can't believe I hadn't noticed already, given all the times I'd seen it before. She's got this way of rubbing her thighs together that I used to think she did just for show but eventually realized is totally unconscious, and she's doing it just then. Her hands are gripping the wheel tight and she's leaning back against her carseat at a weird angle.

I'd been wrapped up in my own thoughts, just replaying the game in my mind to see what I'd done wrong, but now I forget it entirely. Angie and Audrey are both right next to me getting more and more desperate, and well... you can imagine what it's doing to me."

"Your stepmother had conditioned you thoroughly."

"Yep. I keep glancing between them, watching them get worse, and it's turning me on so bad I feel sick. Audrey and I ask Angie to pull over a few more times over the next couple hours, but she just goes off again about how Audrey should've gone earlier, she should know better, she can act her age and hold it. She's watching Audrey too; she even moves the rearview mirror down off the road so she can see Audrey's lap as she squirms. She's obviously enjoying it."

"How ironic that the opportunity for revenge on her daughter should present itself such a form. But perhaps she had planned it that way?"

"I don't think so. I mean, Audrey really could've gone at the restaurant. I think Angie just saw the chance and sunk her teeth into it.

Anyways, the trip goes on, and any lingering doubts I have about how far Angie's willing to push this are put to rest by the manic look in her eyes. Audrey's just quiet, apart from occasional little whimpers and moans of pain. She's quit begging and pleading with her mom and now she's just focused on not losing control. Bit by bit she gives up trying to keep any kind of composure until she's full on holding herself, pushing both hands into the crotch of her jeans. She's undone the button and the zipper, and when I look at her I can see a little strip of her white panties underneath.

Meanwhile, Angie's not doing much better. I don't know how she keeps the car so steady, because she sure isn't steady herself. I'm worried for what'll happen when her body finally gives in; I mean, we're going about eighty miles an hour. But then the exit signs we're passing start looking more familiar, and I see we're almost home. I hadn't noticed with everything being so dark outside, but we'd actually been making good time.

I turn around to tell Audrey, but when I see her the words just dry up on my tongue. Her face is white. Thick tears are falling down her cheeks. Even as close as we are, I know she isn't going to make it that far. I don't know if she can make it another five minutes. I turn back to Angie and figure I've only got one card left to play.

'Listen,' I tell her, 'if you don't pull over right now, I'm gonna tell Audrey about everything you've -- everything we've done. All of it.'

Which I guess was the wrong thing to say.

'What do I care?', she screams, 'you'll probably tell her anyway, the little bitch, if you haven't already. You've already taken her side. Well, now she can know the whole story, not just the parts you decide to keep. She can hear all about how much you get off watching me hold my piss 'til it's dripping down my legs, how hard it makes you to lick it up after. She can hear how much you love to cum in your own stepmother's pussy while it's still leaking all over you--'

It's too much to take; I shout back at her that she's the one who started pissing herself right in front of me, did it again and again until it broke my brain, forced her way into the shower with me in there naked and told me to strip off her wet clothes--

But I'm interrupted then by a sudden sob from behind me. Angie and I both look back at Audrey; she's staring straight down and her face is almost hidden by her hair. Then we pass under a streetlight I see the shine of a thin little stream filling the crease where the bottom of her seat meets the backrest.

It's inching slowly outward from the back of Audrey's jeans. On her other side the stream has run even farther, almost to the car door. A moment later I see the inner part of her jeans below the knees growing dark and realize she's been leaking for a while and the whole bottom of her jeans must already be completely soaked through.

Finally she looks up, and her face seems almost lifeless under the tears. Her eyes meet mine, and in that instant I see every part of her body give up its tension and hear the sharp hiss of pee streaming hard into her seat. The little runnels on both sides of her turn into full-on pools rising up the sides of her legs, and more piss starts trickling from between her knees down to the floor.

Angie's raving at Audrey now, cursing her for making a mess and ruining her car, but I can hardly hear it; my own heart's pounding too loud in my head. Audrey and I are still staring at each other, and I know she knows that it's all true, everything her mom said. She knows what the sight of her sitting there wetting herself is doing to me, knows I'll never be able to look at her the same again."

"And... this is true? Your perception was altered permanently?"

"Yeah..."

"You know, I've seen other cases of sexual fetishes growing potent enough to bridge the divide between those we consider acceptable objects of our desire and those we've compartmentalized as unacceptable. But again, I digress into abstractions. Do continue."

"Okay. Well, soon the car turns and brakes and then there we are pulling into our driveway with the garage door opening up in front of us. I don't even remember us getting off the highway, but we must have. The garage always seems huge and empty without Dad's truck in it. Angie shuts the engine off and closes the garage door, and the silence after that is so heavy I'm almost afraid to breathe. When Audrey opens her door we can hear every little trickle of piss falling from the floorboard to the concrete, and then comes the squelching of her sopping wet sneakers as she steps down out of the car.

That sound follows her every step as she circles around to the driver's door and stops beside it. I leave the car next but she doesn't even look at me. Finally Angie opens her door and gets out too.

The moment Angie's door closes Audrey jumps on her, grabbing her and slamming her into the side of the car. I run over to them as fast as I can and grab Audrey and hold her back just before she can start hitting Angie. I'm in good shape and I've got maybe fifty pounds on Audrey, but even so I can barely manage to keep her off her mom. I'm holding her around the waist, pulling her into me; I can feel the wetness from the seat of her jeans soaking into my sweatpants and I know she can feel my stiff cock against her. But she just keeps swinging and grabbing at Angie, who's leaning on the car almost doubled over, hands on her knees, shuddering all over and trying to catch her breath.

Soon though, Audrey realizes she isn't gonna get at her mom without getting out of my grip, so she goes after me instead. She tries to hit me, kick me, use her elbows, but when she turns around I put her in a wrestler's clinch so she can't get enough momentum behind the blows to make them hurt. She's struggling to get out of it and I'm struggling to keep hold of her and warm pee is getting squeezed out of her jeans and getting all over both of us and then her lips are on mine; the hitting stops and she holds me as tightly as I'm holding her and we kiss like we've been waiting all our lives for the chance.

It feels like being woken from a dream when I hear a muted little wail behind Audrey and break away from her to see Angie staring at us with her hands over her mouth and tears streaming down over them. Her eyes and forehead are twisted up with anger, but it isn't the cold sort of anger she's been giving us for the past month, it's more like an out-of-control rage. She looks like she's about to come tear our heads off but she just stands there leaning on the car door, tensed and bent over and shaking.

Then I see the crotch of Angie's tight gray pants beginning to darken. The wet spot streaks slowly out to both sides and down the middle of her thighs, and meanwhile her knees start to give and she makes this sort of slow-motion collapse, sliding down the side of the car until she's sitting huddled on the cold concrete floor with her head on her knees and a puddle spreading out under her.

Seeing her like that, wet and crying and moaning with humiliation and relief, it takes me straight back to that first time with her in the shower. In that moment I forget all about how awful she'd just been to me and my sister; I drop to my knees beside her and take her cheek in my hand and kiss her too; I suck and lick and pull her lips into mine as the heat of the puddle below rises from my knees and my legs up through the rest of me.

I hear the soft splash of Audrey's sneaker behind me a moment before I feel her hand on my shoulder. I brace myself for her fist, but it doesn't come. Instead it's her face that brushes mine, the warm ridge of her nose pressing my cheek. It lingers there for just a moment before she turns to her mother, her lips open and trembling. Angie's mouth opens just a hair, her eyelids close... and their faces meet in long, deep kiss that I'm half-scared they'll never be able to break out of.

Everything after that is kind of a blur. I remember Audrey jokingly chiding her mom for making a mess of the floor as we leave the garage, and then watching Angie's shiny wet ass swaying in front of my face as I follow her up the stairs. Then we're all in me and Audrey's bedroom and Audrey's slipping off her ruined jeans and I can see the outline of her pussy through her soaked white panties.

She falls back across my bed with her pale legs parted and I fall between them and press my tongue against the thin cotton; I taste what she'd been straining to hold inside her for so long. From the corner of my eye I see Angie bending over Audrey and pulling off her shirt as I lick and suck 'til Audrey's panties are as wet and sticky with my spit as her piss, and then I get up and slide them off her so I can taste her again with nothing in between us.

Little milky white beads are dripping down the bottom of the pink lips of Audrey's pussy now, and I smear them up over her clit with my tongue. She's writhing up and down like crazy and I have to grab her thighs and hold tight to keep her in place. Then I feel something rub my forehead and look up to see Angie's wide ass right above me. She's naked now, straddling Audrey with her knees squeezing her daughter's ribs and their bare, wet pussies just inches apart.

The sight is too much of a temptation for me. I rise up and grab Angie's ass to stop her wriggling enough to ease my cock into her. Angie's lips let go of her daughter's small, dark nipple just long enough to give a cry of pleasure as I thrust inside her harder and harder, letting all the anger and helplessness I'd felt in the car well back up in me and then out of me through the effort. Angie's moaning comes and goes as her mouth is freed and then muffled again with Audrey's skin, with her breasts and neck and mouth. Angie's hand snakes down to take up where my tongue had left off, stroking and squeezing her daughter's swollen clit.

Soon Angie pulls away from me, hugs Audrey tight, and rolls over with her so that it's Audrey's ass rolling and bumping on top of hers. I put a hand on it, unsure, and Audrey arches her back and spreads her legs to show me beyond all doubt that she's offering herself to me completely. I take my cock, still slick and dripping from being in her mom, and slide the tip gently into Audrey's wet and waiting slit.

Immediately she rocks against me, trying to pull me deeper inside, tightening and tensing around me like she's trying to imprint every detail of the texture of my cock into her flesh forever. I work it in and out while her and Angie kiss and caress and rub each other under me, and what feels like only a moment later I feel it burning and rising inside me, the relief I'd been aching for all the time I'd had to watch Audrey and Angie squirming and struggling and finally giving in. I let it pulse over my whole body and grow more and more intense until it's too much and it overcomes me entirely and my cock spasms and shoots hard into the deepest part of Audrey it can reach.

After that I fall back on my bed and things get blurry again. At some point I feel both of their bodies resting against mine; I remember enjoying the feeling of Angie's big, full breasts pushing into the left side of me and Audrey's small, firm pair pushing into the right. I think I wake up once and see the two of them still going at each other in the darkness. I know that when I get up the next morning both of them are still next to me, and the bedsheets we're laying in are absolutely soaked."

"It seems to have taken less... persuasion for you to involve yourself with your stepsister than with your stepmother."

"Well, when you've already got one fucked-up secret relationship going in the house, what's one more?"

"Indeed. And perhaps your sister felt that joining in an existing affair of this nature was easier than starting one from scratch?"

"Probably, yeah. Also, with the three of us in on it, it actually got easier to hide. Angie could start making her nightly trips to my room again."

"And tell me, did this sexual union manage to put to rest the conflict between mother and daughter which had gotten so very vicious?"

"Well... for a while, yeah. For a while they got on better than they had in ten years. But then--"

"Ah, I apologize, but I've just noticed the time. I'm afraid I've let us go on over our hour, and the rest will once again have to wait. I shall see you next Thursday."
