[unseelie-slut]

Your big sister came home from that big party she'd be talking up all week, with a sheepish expression and proverbial tail between her legs. You enquire, somewhat smugly, what went wrong - but the genuine and unguarded answer shakes you of any potential mockery you were hoping too cook up.

She said the minute she got any booze in her, all she could think about was coming home to her little sister. Your heart soars, for so long now it's felt like you and your beloved big sister were drifting apart as she got older, seemingly deciding she was too cool for you. You still don't fully understand how alcohol WORKS, you know it makes adults act dumb or like kids. So it warms you to think your sister couldn't it drink it without being sent wandering back into your arms.

She's wrapped around you now, laying ontop of you all heavy and warm. Her slurred breath smells a bit like Dad's whiskey, as she whines softly about how much she loves you and she misses you. It's almost to good to be true, that she'd be feeling all the same things you were. It almost is anyways, but her heavy hands palming at and roughly gripping your tender budding breast grounds the moment in messy reality.

The more strained gasps and yelps escape your throat, the more you try to wiggle out of her grip - the more bold and excited her hungry hands get groping and gripping all over your body. You know enough to know, big sisters aren't supposed to touch their little sisters like this. You especially know you shouldn’t feel the sizable bulge tightening in her jeans pressing against you as she began to grind herself against you.

You try and say something, anything - a weak and soft protest escaping your lips as she shifts back only enough to undo her jeans pushing them down only so far as is enough for her sizable member to spring free, veiny and twitching in anticipation. She only shoots back muttered drunken and teary eyed replies about how much she loves you and needs you. You say nothing more as she pushes your panties to the side - and slowly, achingly slowly she presses each inch of her length into your cunt, wet and buzzing with the wrongness of it all. All the while, between her breathy gasps and stuttered groans, she whines about how much she loves you. How she never wants to be apart from her sister. You don't understand, and it hurts, and feels wrong. She picks up speed now, thrusting in and out somehow going DEEPER into you with each thrust - and you feel so violated, so undone. Tears are streaming down your confused face as you try to bite down your own strangled and confused moans. But... your big sister is FINALLY paying attention to you again, like you'd been dreaming of - how could you say no? How could you say no even if you wanted to?

getting bred by a girl who’s also your big sister

Big sis let’s me sleep in her room for the night, but I’m only allowed to sleep on the floor. It’s so hard and cold and I beg her to atleast give me a pillow.

“Hmmm ok…” she looks down at me and smirks “but you gotta earn it, I’m not giving anything to a spoiled brat.” I whimper at that and I swear I could hear her laugh. From the other side of her bed she grabs my favorite stuffed animal and tosses it on the floor next to me. “You wanna be comfortable lil sis? Hump that toy of yours like a dog” I laugh at her request but she doesn’t, she’s dead serious. “go on mutt, get off with it.” I weigh wether it’s better to let my big sister degrade me or freeze, and I finally mount the stuffie, stifling whimpers as I brush my pathetic little dick on it. “What are you doing? Dogs don’t wear clothes. Take them off or I will”. I try to protest but big sis starts to get up, a mean, scary look in her eye and I know if I don’t listen I’ll have torn clothes and a mountain of bruises. I’m left shivering in my cute panties, my tits out, and big sis cooing over me. I start to hump the stuffed animal again and it feels so much better than before, it’s so warm and the lack of clothes makes me even more sensitive. “Such a good girl little sis, I have a treat for you! Such a good dog! Don’t act like you haven’t been eyeing them before”. In front of me plops her panties, and almost instinctively I grab and huff them, so hard in fact I get dizzy. In all this pleasure I let out a few barks, and that snaps something inside big sis. She starts to come behind me, and smacks my ass hard. The shock makes me tear up a little, and for some reason hearing me snivel and cry gets her even more excited. “Keep fucking that toy of yours mutt, if you cum while I beat you up I’ll never let you live it down”. For the rest of the night all she does is beat on me, kicking me in the stomach, punching my sides, spanking me red, fingering my pathetic little holes. She starts to jack off over my face, telling me all the fucked up plans she has for her new fleshlight before she finishes and has me clean her up. By the end I can’t even move, my legs are all jelly and I’m so bruised even the occasional twitch hurts. Big sis flips me over to see an enormous puddle on the plush, strings of cum connecting it to my useless little cock. “Awww little sis I told you not to cum… oh well, you’ll make it up to me tomorrow, I got big plans for you after all~” She goes back to bed and tosses a thin blanket and a singular pillow down for me, and that’s more than a puppy should ever ask for.

Big sister who likes fondling your tits as they grow in so she just keeps making them get bigger, more sensitive, to feel them expand under her kneading till they're so oversized you can't do much besides lay there and moan.

Seducing my masc tboy little bro as a dom fem big sis is the most moral thing i can do. I need to press my big boobies up against his chest and grind my bulge into his crotch. Teasing him relentlessly and giving him sisterly kisses to silence his protestations until all of that masc chivalry is replaced with raw need and the list for big sis cock.

the urge to use my sleeping sister as a fleshlight

[sillygaydeer]

Little sisters love to hit and berate their older sisters till eventually big sis either submits to them or takes their aggression out on them, either way it’s gonna end with one of them getting pregnant

[kittygoopaw]

Big sis whose been on HRT a while, so her dick doesn't really work as good as it used to. However, she'll still stuff the half-hard length in your mouth to make you sit there warming it for her. Her scent has only gotten stronger, too, and every time you're let go to do something else you still smell her on yourself for hours

Ever since she found this strange book, she has been so intrigued with the secrets contained within them. So many interesting rituals and spells recorded within it.

It's all bogus, naturally. But it's pretty bogus, written in gorgeous fonts and with - honestly? - pretty hot drawings sketched in.

But there's one spell there that she has not been able to get out of her mind... The Body Takeover.

For the past week and a half it's been weighing on her mind constantly. Like she's drawn to it, her mind keeps wandering to that page in the book.

Fuck it. It's bogus anyway, but might as well try, right?

But who to try on, she wonders. She would need a hair of her "hopefully willing subject", as the book so optimistically puts it, so there's only a couple of options really. Definitely not mom and dad, that's for sure. It's gotta be either her girlfriend - no, can't do that, she's too busy and is barely coming over anymore - well it's got to be her then.

When nightfall arrives, she waltzes over to their shared bathroom, scans for her little sister's hairbrush, and plucks a few strands out from it. "This is so awkward" she thinks. But, well, it's bogus, right?

She retreats back to her room and gets to work. She prepares everything as it's shown in the book, she lights the candle in the middle of everything else, and chants the words inscribed on the page. Once she's done, she takes the strands of hair and lays them down in the flame.

That nasty smell of burning hair immediately hits her nose, it causes her to tear up and blink a few times. Once, twice, three blinks, and her room goes dark when she opens her eyes again.

She's in bed now? So was this just a dream? She exclaims "huh?" then her eyes grow wide when the voice coming out of her is not her own, but her little sister's sweet voice. This is her sister's room.

It worked?! She frantically looks around the room, barely lit by the moon peeking through the blinds. By her side, on the bed, lies a book. Is that...? It must be her journal. She shouldn't, she knows she shouldn't, but, she literally is her little sister right now, so why shouldn't she?

She gets up and takes the diary over to the desk, flicking on a little light, and skips to the most recent page. She's in disbelief at what she sees.

"I don't know what to think anymore. She's been looking at me all day again. But even more than she had been the last two weeks. I feel so seen by her. Does she know? Has she figured out my massive crush? Does she think I'm a disgusting freak and now she's always judging me? Not a minute goes by anymore where she isn't on my mind. I touched myself again to the thought of her last night but the thoughts are getting worse, I wish she would just barge in and kiss me and take me and not give a shit about what I think and- fuck, get it together! Of course she wouldn't. I'm the worst. But she still treats me the same as always, so at least she hasn't let on that she thinks I'm such a fuckup. I love you sis..."

The rest of the page is filled with tiny scribbles and the words "I love you big sis" repeated a few times, increasingly more disordered, until it ends.

...

---------

A few days later, she texts her little sister the words "I love you little sis", waits a few minutes, then takes over her body again. The spell has become easier; she does not react so strongly as she did last time to the burning, and smoothly glides over into her sister's body.

This time, she awakes not to her sister calmly resting, but to her touching herself with one hand while the other keeps the phone in hand, with one message highlighted. "I love you little sis".

"Holy shit, she's wetter than I've ever been" goes through her head as she picks up where her little sister left off. Her fingers are a bit clumsier, she doesn't know what spots feel best to this body, but as if this body naturally reacted to the presence inside it, it feels absolutely electrified. Like it senses those fingers aren't truly hers. The love for her big sister has etched itself so deeply into her that even her body instinctively reacts this viscerally to just her big sister's spirit.

It doesn't take long for her to orgasm, and oh what a big one. Her mind and body go into overdrive as she takes this body above its peak. She shakes and whines and whimpers until her body goes limp. Her own body could never feel this good.

She pants, spent from making her little sister cum this hard. She gets one last idea and, with a malicious grin, grabs the phone and snaps pictures of her bare body, trying to keep all the important bits censored. Trying, because her hard nipples are clearly on display in some of them. She sends those pictures over to herself as a reply to the "I love you" message, captioning them "I am thinking about you big sis".

Oh she's going to have so much fun with this.

Do I give off more stepmom energy or big sis energy. Just asking because the whole fauxcest rp/kink is getting me pretty worked up and I need to figure out my role so I can make all my posts the same.

[plantmommyposadist]

I just called my girlfriend big sis because she has been on estrogen a year longer and she got so mad because im 5 years older than her and she was already kinking off that first
