what's yours is mine

[sharingsisters]

They say that one time is an accident, two times is a coincidence, and three times is a pattern. But that's not always true.

For instance, it's really hard to brush off "I seduced my older sister's college-age girlfriend" as an accident. And it's really hard to brush off "I seduced my older sister's college-age girlfriend twice" as just a coincidence.

But Jeanne can't help it. Her sister Annie has been away at college nearly all year; Jeanne got used to using her things when she was gone. And now that Annie had been home over the summer break working a temporary job and brought her girlfriend to meet her family, well...

Really, it's not her fault. She's a striking young woman, slim and blonde and feminine and beautiful. She catches eyes of men and women everywhere she goes. Is it any wonder that Annie's girlfriend's eyes had started wandering? Of course it isn't. And when she sees someone looking at her - someone who she spends most of the day alone with, because Jeanne is on her own summer vacation - she can't help but want to indulge in that gaze.

And she had indulged in it, all right. Gaze and hands and lips and tongue and more besides.

But it had just been a one-time thing, Annie's girlfriend had made clear. Jeanne and Annie look like sisters, after all. Sure, Annie is taller and a little more muscular and her boobs are bigger and she wears her hair much shorter, but there's still an undeniable similarity. It's understandable that she'd err once, but just once.

Only once.

At least until Jeanne had gone for a swim in their backyard pool and seen that Annie's girlfriend had been sneaking peaks at her in her bikini out the window.

Because now Jeanne is straddling her sister's girlfriend's lap on the couch in the living room, still wearing that same bikini, her hand brushing the older girl's shoulder.

"C'mon... Annie won't be home for like two hours. Nobody's gonna find us."

Ishiko had been delighted when her new girlfriend had invited her home to meet her family over the summer. They'd spent the semester getting along incredibly well, so meeting parents (and her sister) had seemed like a great way to spend the summer. Besides, it would give her an excuse to get away from her own home for a while longer. And at first, it had just been that - parents and the family home and the little sister and that had been all. But...

Things had gotten strange.

And maybe it was her fault.

After all, Jeanne did look a lot like her sister - but somehow she exuded an energy that drew the eye and one thing had led to another and she was a little ashamed (a lot ashamed) about what she'd done and how things had ended up. She'd told her, after the glow had faded and guilt had crept in, that she wasn't going to do this again. That it was a mistake. That they should just act normal the rest of the summer.

But that swimsuit had drawn the eye and then-

Well.

Her face burns as she gazes up at Jeanne from where she straddles her lap, Ishiko's hands on her hips, her breath catching.

"That... that isn't the point, you know," she half mumbles, as if she's trying to convince herself as much as Jeanne, "I... I told you that we shouldn't do this again."

But her heart is racing and her gaze keeps tracing the dip of a collarbone. The bare shoulder. The way her hair falls. It's... intensely attractive.

[sharingsisters]

Ishiko had said that, and Jeanne had agreed.

But that had been then, and this is now, and Jeanne's opinion has changed. "Mmm... yeah, you did say that," she murmurs.

She leans in, dipping her head to start kissing the side of Ishiko's soft neck, nuzzling into the place where neck meets collarbone.

"So push me off. Push me away, and I'll listen. I'll stop. If that's what you really want."

Her hands are on Jeanne's hips, right above the ties of her bikini bottom. It's not a place you touch when you're not into it.

[palemask]

Ishiko makes a low noise - almost a whimper - as she feels lips brush against her neck. Her fingers clench, curving against the skin where her hands rest. She should push her away. She should stand up, walk away, pretend this never happened. Jeanne is right - or at least she's not wrong when she says she could stop this if she wanted.

Instead her hands shift a little. Fingers splay against the smooth skin of her belly hook into the ties on one side of her bikini. Almost (it is) an invitation as her head goes back to expose more of her throat.

It just gives her a fig leaf of deniability. At least for the next few heartbeats.

[sharingsisters]

The invitation is offered and taken. Jeanne peppers kisses all up and down the side of Ishiko's throat, sweet and loving and warm. Her hand slips to the back of Ishiko's neck and then slides up, fingers twisting in dark hair.

Ishiko probably can't feel it, but Jeanne's lips shift into a little smile when she's not pushed away.

"Can you blame me?" she purrs, kissing upward until she lets her teeth graze Ishiko's earlobe. "That tongue of yours... mmm, you made me cum so hard last time. I haven't been able to stop thinking about how you made me feel, Ishiko."

And speaking of tongue, she shifts to the side so that she can take Ishiko's face in both of her hands and lean in for a deep kiss, her tongue sliding into the older girl's mouth.

[palemask]

It feels so good. She can't help herself; especially not when the memory of them locked together still likes to come bubbling up to the surface even now. She tilts her head with a low, raggedy little exhale and then leans up into the kiss before she can reply. Before she can say something else she might regret later.

But her hands are moving. Her hand skims up her front and she fondles a breast through the bikini top, palming it, grinding her hand against the nipple, letting her fingers sink into the soft flesh as the other skims down and over a thigh and then between her legs - again, over fabric, but offering something for Jeanne to grind herself against.

She tastes sweet, she thinks.

[sharingsisters]

Jeanne's not as busty as her sister is, but she's hardly ashamed of her modest chest. Her breasts are perky and shapely; what does she give a shit about size? Her nipple is already starting to stiffen and peak against Ishiko's attention.

And then there's the hand between her legs. Jeanne obligingly starts to grind her hips forward, pressing the crotch of her bikini bottom against the older girl's palm and fingers. The kiss is deep, hot, fierce until Jeanne breaks it, a little tendril of saliving connecting her tongue to Ishiko's lips.

"...do you wanna fuck here, or go upstairs to my bedroom?"

The living room is nice, well-decorated, with plenty of furniture that would make for an excellent time. But even if they should be alone for at least a couple of hours, well, it's a little harder to scramble to put clothes on when the front door is a short hallway away.

[palemask]

Ishiko is breathless and almost panting when the kiss breaks, looking a little bleary, her mouth gaping for a long moment before she can settle herself again. She can't help it - not when Jeanne is pressed so close in her lap, not when she's warm and close and attractive. It's not fair. She swallows hard, her eyes darting away as she tries to form worms, her fingers slipping from her breast so her arm can wrap around her.

"...we - we should go upstairs."

She starts to stand, urging Jeanne off of her lap - but she finds her hand to tug her along. She doesn't want to look back. If she stops to think for too long she'll be lost. But right now there's a heat in her belly and a drumbeat in her head - all very concerned with the intensely attractive high schooler who wants to fuck her brains out.

[sharingsisters]

There's only a moment's pouting from Jeanne as she's pushed off Ishiko's lap - mainly because she knows that this is the moment's delay she'll have to put up with for greater satisfaction. She's happy to follow the older girl's lead as they go up the stairs, passing Annie's bedroom (which she shares with Ishiko while the girl is staying here) and the corridor to their parents' bedroom, to her own room at the end of the hallway.

Jeanne considers, for a moment, suggesting to Ishiko that they fuck in Annie's room, but that'd probably be a little too much for Ishiko's guilt.

As soon as they're in her bedroom, Jeanne practically pounces. She leans up on the tips of her toes to fiercely kiss the taller girl, her hands settling on Ishiko's hips and squeezing.

"I kinda just want to have you get on your knees and eat me out," she purrs against the other girl's lips. "But if you have a better idea, I'm all ears~"

[palemask]

It's probably a good thing she didn't suggest that, because that might have been enough to push her away from this terrible idea. Maybe. As it is, she turns back to face Jeanne as the door closes behind him and leans down to return the kiss, her hips swaying slightly as she tries to wrap her head around everything that's happening. It's just... fast. But not fast enough. She can still think about all of this. There's a little noise from her - part frustration, part want.

"N-o..." She murmurs, kissing a line from her lips to her throat, dipping lower as she starts to sink to her knees. Her heart is hammering away and there's that clench of arousal between her legs - heat and slickness at the thought of being able to taste her all over again.

"That sounds fine-" Her breath escapes in a low sigh as her lips trail between her breasts and then lower still, her fingers tugging at the little ties that keep the bikini bottoms on. She needs to do this before she thinks better of it.

[sharingsisters]

Hands on Ishiko's shoulders, pressing her down to the floor, down to her knees. For a moment, Jeanne considers sitting on her desk chair, or the side of her bed, to make things a little easier.

No. No, she wants to stay standing, at least as long as she can stay standing for.

It's so easy to tug on those ties for her white-and-pink bikini bottoms, to have the scant garment flutter to the floor. Jeanne's fingers tease one of the ties but don't actually do it. She wants Ishiko to do it herself. To expose her neatly shaved pussy.

One hand settles on Ishiko's head.

"You're so sexy, Ishiko... I can't wait to watch you lick me."

[palemask]

Ishiko's cheeks burn. She can't put into words why it is that Jeanne seems to have such an easy time goading her. Getting her to do these things. She swallows hard and then her fingers tug and unwind and allows the garment to fall to the floor. Her eyes widen a little and she drinks in the sight of her from where she's settled on her knees - the smooth skin, the slit, the hood of her clit. Shebites down hard on her lower lip and her hands hover before they settle against Jeanne's thighs and she leans in, her breath rushing over pussy as she leans close and closer.

"God, you look so good-"

She mumbles and her restraint finally seems to snap. She noses in against her and the wet firm press of her tongue laps up and over her cunt, getting a taste of her, smearing her saliva against her lips as every nerve in her body seems to jangle and stand on end.

[sharingsisters]

This is the benefit to not having big boobs - Jeanne can look down and watch as Ishiko's face slips between her legs, as her tongue slides over warm folds and the little button of her clit. It's intensely erotic, and Jeanne bites her lip because if arousal was pleasure she'd risk coming then and there.

She inhales. She exhales, murmuring little noises of approval as that tongue washes over her. "Fuck, you're so good at this," Jeanne murmurs. She rocks her hips only slightly against Ishiko's tongue.

She wants to ask so many questions about how Ishiko and Annie have sex, but perhaps she'll save that dirty talk for when they're deeper into it. "Mmm, just like that. Your tongue feels so good..."

[palemask]

The compliment makes her body shiver. There are goosebumps running up her arms and she can feel herself clench as another jolt of heat runs straight into her belly. And really... her focus is on Jeanne and the way she tastes. The way her warm cunt feels against her tongue. She drags her tongue across her again, sliding up and over her clit and then again - slow licks and then a faster one as her hands inch closer, her fingers starting to spread her so she can let the tip of her tongue slip into her.

[sharingsisters]

Ah, bliss.

Jeanne sighs, her eyes sliding closed. She tilts her head back towards the ceiling, not wanting to look at the pretty older girl on her knees eating her out. She wants to focus on the sensation, on how it feels to have that tongue slide along and inside her heat.

An exhale. And an inhale. She's making more noise with every breath, especially as fingers slip into her.

"Oh, Ishiko," she breathes. "Mmm... I'm not gonna last too long if you keep it up like this..."

She rocks her hips forward. Both of her hands settle on the girl's black hair.

[palemask]

The noises that Jeanne makes send a wave of heat curling through her. Arousal, intense and deep, just from the way the girl breathes. Just from the feeling of slick, wet heat on her tongue and the sharp taste of her arousal. She makes a low noise as a pair of her fingers brush gently against her clit, teasing and circling, eased by the slickness she's made. Her tongue flickers a bit deeper, curling against her inner wall, hoping to find that spot that she knows (knows) will make her fall apart and go weak at the knees.

She's consumed by this, in the moment, no matter how guilty she'll feel later.

[sharingsisters]

Jeanne grips tight fistfuls of the older girl's hair. The fingers against her clit feel nice, but not nearly as nice as that tongue. Her knees, quite literally, tremble - the grip in Ishiko's hair is just as necessary to steady herself as it is an aspect of control. "Ishiko, you're gonna make me cum, you're gonna make me cum, I'm gonna cum--"

She gasps, her body tensing and tightening. She bends forward, leaning over her sister's girlfriend, a quiet but insistent orgasm that leaves her shaking.

Eventually, Jeanne straightens up, sucking down air. She looks down at the other girl.

"So, who has the better pussy, me or Annie?"

There's a moment and then she giggles, her expression dreamy and tired. "Sorry, that's not fair of me. You don't have to answer."

[palemask]

There's a burst of heat and pride as Jeanne spouts those words - she's making her fall apart - and she grips a little tighter, her tongue delving a little deeper, desperate and wanting and eager. But then as it starts to wind down, Jeanne asks that question. She leans back, fingers lifting to dab at her mouth and chin where the smear of her arousal still lingers.

"I-"

Her stomach twists a little.

"...that is unfair. Don't - don't ask that kind of thing."

The guilt is - what? Almost enticing as much as it is off-putting?

argh I didn't notice the italics

[sharingsisters]

"Yeah, yeah, I know, it's not fair," she says, her tone genuinely apologetic.

So why is it so hot?

Jeanne's hands settle on Ishiko's shoulders; one slides to her cheek as the younger girl kneels and kisses her deeply, with tongue, tasting herself on Ishiko's mouth and lips. "You're so good at eating pussy, Ishiko. I could have you on your knees making me cum all day..."

Her fingers grip the other girl's chin. "But are you really okay with not coming yourself?"

no worries!

[palemask]

Ishiko swallows hard and then leans into the kiss. It's breathtaking and it makes her stomach churn in a couple of different ways. Her hands life, hesitate, and then she wraps her arms around her with a low sigh. Her toes curl and a part of her thinks that it's all she wants - to just eat her cunt and taste her, feel her arousal run over her chin-

She blinks blearily.

"I - I do want to-"

She's aware of how wet she is. How slick. She's intensely turned on, the tension in her frame taut and needing a release.

"You can use your fingers - or-" Her cheeks burn, "A toy? Or maybe your mouth?"

There are options.

[sharingsisters]

There's a pause as Jeanne thinks, pulling back just a little as she leans forward, pressing one hand to Ishiko's thigh as she fights the urge to go in for another kiss. She chews her lip for a moment.

And then grins wickedly.

"Weelll, I don't have any toys; I'm too young to go buy them."

The hand on Ishiko's cheek slips up to tease her hair. "Unless you and Annie brought something home that we can use, perhaps? I'm sure Annie wouldn't mind me putting a toy to its intended purpose~"

Not that she's ever used anything like a strap-on before, but a vibrator shouldn't be too hard, right?

[palemask]

"Well-" She glances away again, eyes tracking over the room. There is... something. It's nothing complicated. A little vibrating bullet they've used, but it would work fine for this. But is she really going to-

"The drawer in the nightstand. Second from the top."

Her cheeks are burning again.

"There's... a little vibe there that we've used."
