Chapter 1: Introduction
It's Saturday on the boat at Sam and Chad's lake house, and everyone is having a great time. Sam and stef have bikinis on. Stef has a slimmer build than Sam, and her toned body is shown off by her suit. She has smaller B cup tits, but had enormous DD tits while breastfeeding their last baby. Kevin loves big tits, and always jokes he wants to get her big fake tits. Sam is a little thicker than stef, but not overweight. She has D cup tits, that are shown off by her bikini she has on today. Kevin keeps grabbing peeks of her tits when the opportunity arises. At one point, Kevin thinks Sam may have caught him staring. They all head back around dinner time and eat dinner at the house. They're all having some drinks after, and Chad has had way too many. He stumbled off to bed and passes out. Kevin and stef say they're tired from being in the sun a little later, and say goodnight to Sam. "I'm going to bed too, right after this glass of wine", Sam says.
Kevin, still nursing a beer, feigns a yawn, "Yeah, me too. No sleep till the sun comes up, am I right?" Sam chuckles, shaking her head. She gives him a playful slap on the shoulder as she walks past him. "You're such a lush, Kevin." He grins back, trying to look as casual as possible.
As Sam turns to sit back down at the kitchen table and have more wine, Kevin gets a glimpse down her loose shirt at her cleavage in her bra. He's going to use this image to fantasize about when he fucks stef in a few minutes. He'll imagine he's balls deep in Sam, pinning her down, fucking the shit out of her. He'll wonder if she yells or moans or whispers fuck. No fucking clue, but he's gonna find out. One day.
Kevin takes a final swig of his beer, stands up, and heads to the bedroom him and stef are staying in.
Once inside, stef is already laying on the bed, wearing a pair of silk shorts and a tank top. Kevin can still see the faint outline of her bikini top underneath. He smirks, knowing that he'd get her out of both before the night is through.
"You know," he says, slowly unbuckling his belt, "I've been thinking."
stef props herself up on an elbow, her eyes narrowing. "About what? Not that fake tits again, I hope."
Kevin shrugs, unbuttoning his shirt. "Maybe.
Maybe not. But I was thinking about how much fun we used to have." Kevin shrugs off his shirt, revealing his toned chest. He steps out of his swim suit and boxers, revealing his already semi-hard cock. stef raises an eyebrow, a smirk playing on her lips.
"Oh yeah? And what kind of fun did we use to have?" she asks, running a hand up her thigh, subtly teasing him.
"You know, the kind that involves you, me, and a whole lot of screaming," Kevin replies, walking towards the bed.
stef laughs, shaking her head.
"Well, we are still married, aren't we? Maybe I should remind you why that is." She reaches behind her back and unclasps her bikini top, letting it fall away to reveal her small, perky breasts. Kevin's cock twitches at the sight, but he knows he can't just dive in yet. He wants to take his time.
"Oh, I remember," he says, his voice low. "But I also remember that sometimes, you need a little... encouragement to get going." He reaches out and runs the back of his hand down her side, making her shiver. They start to fuck. Stef on top, doggy, missionary, all positions imaginable. Stef is screaming as she has multiple orgasms, and the sound of their bodies slapping together fills the air. Meanwhile, in the kitchen, Sam hears some faint noises over the music playing in the kitchen. She gets up and leans in to the wall, where they're coming from. "Oh my god, they're having sex" Sam whispers to herself as she can hear Kevin and stef through the wall. Sam can hear the bed squeaking as Kevin and stef are fucking in different positions. Either way, Sam can clearly hear Stef moaning and groaning. The noise of the head board hitting against the wall is almost deafening at points. There are times when Kevin hits Stef so hard that Sam swears she can hear Stef's body hit against the head board. Sam her heart beating faster as she tries to stifle a moan of her own. She can't help but feel a searing hotness between her legs as she listens to her sister and brother-in-law fuck. It's almost as if she can feel Kevin's big dick inside of her.
Sam's nipples stiffen beneath her shirt as she listens to Stef's cries echo through the walls. She can't help but let her hand wander down to her pussy, rubbing herself through her shorts. She's so fucking wet, and she knows it's wrong to be turned on by her sister and brother-in-law fucking, but she can't help it. She's never heard anyone fuck like that before.
Back in the bedroom, Kevin has Stef on her back, her legs thrown over his shoulders. He's pounding into her so hard that the headboard is banging against the wall in time with his thrusts.
Stef's head is thrashing from side to side, her screams echoing through the room. "Fuck, Kevin! Yes! Right... Fucking... There!" she cries out, her nails digging into his back.
Kevin grins, a primal, feral look on his face. "You like that, don't you, you little slut?" he growls. "You like feeling my big cock stretch you out, don't you?"
Stef opens her eyes and looks up at him, her pupils dilated with lust. "Yes," she pants. "I love it. I fucking love it. Fuck me harder, Kevin.
Make me come like a little whore."
Kevin's eyes darken at her words, and he pulls out of her, making her whimper in protest. "Turn over," he commands, and Stef quickly complies, getting on her hands and knees.
Kevin positions himself behind her, his cock jutting out, glistening with her juices. He grabs her hips, his fingers digging into her soft flesh as he slams back into her. Stef cries out, pushing back against him, meeting his thrusts.
"Harder, Kevin.
Come on, you fucking bastard. Fuck me like you mean it," Stef chants, her voice hoarse from screaming. Sweat pours down Kevin's back as he gives her what she wants, his hips slamming into hers with brutal force, the sound of flesh meeting flesh echoing through the room like a symphony of debauchery.
Out in the kitchen, Sam is now on her knees, her shorts and panties discarded on the floor beside her. Her fingers work furiously between her thighs, her hips bucking as she chases her orgasm.
She can hear Stef's muffled cries as Kevin fucks her ruthlessly, and it sends her over the edge. Her body tenses, her back arching as waves of pleasure crash over her. She bites her lip to stifle her own cries, but a soft whimper escapes her.
She gets up, and puts her clothes back on, and sits back at the table with her wine and music. She can't believe what she just heard, and did. She's never screamed like that from sex with Chad. "What f'in magic does Kevin have in his pants" she wonders to herself. She has never been as turned on as she was just listening to her brother in law fuck her sister. She can't stop thinking about it as she processes what she just heard.
Back in the bedroom, Kevin is speeding up his thrusts and Stef is screaming out "more, more! Fuck me harder!" He grabs her hair and pulls her head back, bending her body into an arch as he fucks her fast and hard. Her big tits bounce with every thrust, smacking against her chest.
"You're my little fucktoy, aren't you?" Kevin grunts. "My little fuckdoll that loves to be fucked raw and hard.
Tell me, you worthless little slut, who does this pussy belong to?" Kevin growls, his cock pounding into Stef with relentless fury.
Stef's mouth drops open, her breath coming in ragged gasps. "It...it belongs to you, Kevin. Only you. I'm your dirty little whore," she moans, her eyes rolling back in her head.
Kevin's grip tightens on her hair, and he pulls harder, making Stef cry out in pain and pleasure. "You're such a nasty little bitch, aren't you?
Taking every fucking inch of my cock like the little whore you are," Kevin grunts, his cock pulsing with need as he feels his orgasm approaching.
Stef's face is a mask of pure ecstasy, her body shaking with each brutal thrust. "Yes! Yes, I am! I'm your little fucktoy, your little slut. I love every fucking inch of your cock inside me," she cries out, her voice barely above a whisper.
Kevin leans down, his lips brushing against her ear. "You want my cum, don't you, you filthy little cunt?
You want me to fill your wet, tight pussy with my hot load?" Kevin hisses, his voice primal and raw.
Stef nods frantically, her breath coming in short gasps. "Yes, Kevin. Please. I want your cum. I want you to fill me up."
Kevin's cock jerks inside her, and he groans, low and deep. "Fuck, Stef. Your pussy feels so fucking good. So tight and wet.
You're choking my cock, Stef, like a fucking vise. I'm gonna come so hard inside you, you little fucking whore."
Kevin slams into her, his hips a piston as he fucks her with primal abandon. Stef's moans and screams fill the air, her body quivering with each thunderous thrust. He can feel her pussy gripping him like a fist, trying to milk his cock for everything it's worth.
Suddenly, Stef's body goes rigid, and she lets out a long, wailing scream as her orgasm tears through her.
Kevin feels her pussy clamp down on his cock, her inner muscles pulsing rapidly as she comes. He slams into her a few more times, before he can't take it anymore. With a shout, he pulls out of her and grabs his cock, stroking it furiously as he aims it at Stef's back and ass.
"Fuck. Fuck. Fuck!" Kevin chants, as he comes hard, his cock throbbing in his hand as he coats Stef's back and ass with his hot seed. It drips down her thighs in thick, white ropes, a filthy sight that makes him even harder.
He falls to his knees next to her, his fingers digging into the soft flesh of her hips as he admires his work.
"Look at you, you fucking mess," he growls, his voice thick with lust. "Covered in my cum. You look like such a dirty little slut."
Stef looks over her shoulder at him, her eyes heavy-lidded and glazed with post-orgasmic bliss. "I am your dirty little slut, Kevin. All yours."
Kevin leans in, his tongue darting out to lick a trail of cum from her hip to her ass.
Kevin gets up and hands stef a towel. Stef runs across the hall to the bathroom, naked, not noticing Sam sitting the in kitchen. Sam sees stef scurry across the hall, her back covered in Kevin's cum. She shouldn't be surprised, but she feels a pang of jealousy. She wanted that. She wanted to be the one covered in cum tonight, but her husband was too much of a drunk. She's never felt so turned on in her life, and she fucking hates it.
She gulps down the last of her wine, the liquid burning a trail down her throat. She wants to feel that same burn between her legs, to be filled and fucked by Kevin like she knows he can. She's tired of being the good wife, and having to be the little fuckdoll for Chad.
Stef goes back in to the bedroom with Kevin as he's already in bed. Stef crawls in to bed, and says "night honey, that was f'in amazing". And she drifts off to sleep. Kevin, still wound up from the sex, and visualizing Sam's cleavage, can't sleep so he's scrolling his phone.
I get up to go to the kitchen to get a glass of water. I'm only wearing boxers because it's late and i think everyone is sleeping, and I'm still half hard from the sex. As i walk out, i hear a shy "hey Kev" come from the corner, and I log and it's Sam, as she takes a drink of her wine .
"Shit, Sam, you scared me," I say, my hand going to my chest. "What are you still up for?"
She shrugs, her eyes fixed on the ground. "Couldn't sleep. Wanted some wine. Thought I'd come out here and drink by myself."
"Yeah, stef has been asleep for a while" I say, knowing that's a lie. "I couldn't sleep though, so I came out" I say, as I grab a wine glass and head to the table where Sam is sitting.
"Stef's been sleeping for a while, huh?" Sam says with some sarcasm in her voice.
I can't help but think she knows about us having sex, but I'm not sure. I knew we were loud, but didn't think we were that loud. "What's that supposed to mean?" I joke back.
"Well, I'm pretty sure i saw my sister walk in to the bathroom with your cum all over her back...... did that happen while she was "sleeping"? " Sam says and gives a wink.
"So I'm guessing you heard me and your sister having sex. Is that what you're getting it? We weren't even that loud" I say, nervously.
Sam takes a sip of her wine, her eyes not leaving mine. "Not that loud? I was sitting over here and i heard stef screaming through the walls." Sam says with excitement. "Did you put holes in the wall where the headboard was hitting? Jesus Christ Kev, what the fuck did you do to my sister in there?" Sam asks, her voice laced with a mixture of shock, arousal, and disbelief. She's sitting at the kitchen table, her legs crossed, but her feet are bouncing nervously underneath her. Her wine glass is halfway to her lips, but she's forgotten about it. Her eyes are fixed on me, her blue irises seeming to burn into mine.
"Well, we may have had a little bit of built up sexual tension. How long were you listening you little perv?" I ask , trying to keep the conversation light, but my heart is pounding in my chest. I can see the desire in her eyes, and I know she's turned on. She's always been shy, but tonight, she's different.
Sam smiles, her lips curling into a wicked grin. "Long enough," she says, her voice low and sultry. "Long enough to know that you fuck like an animal, Kevin."
I raise an eyebrow, my cock twitching at her words. "Is that so?" I ask, adjusting my cock in my boxers, as it's about as hard as a rock now, thinking about Sam listening to me pound the fuck out of her sister.
