"sis!!! let me in!! i have to pee!" you pound on the door. she always takes an hour in the shower, and theres never hot water left for you. youre convinced all she does is hum or dance or something.
"ok. hang on!" you hear the water turn off, then a series of footsteps and clangs. finally the lock clicks and the door opens.
youre greeted by your sister, a thick waft of steam billowing around her. her damp hair clings to her dewy skin, lips slightly parted. her towel isnt so much wrapped as it is slung, loosely around her.
she's all youll ever need.
her beauty is somewhat ethereal, like she's a fairy goddess from one of those shows you watched together as kids. those shows got cancelled or had a shitty ending. things changed, but you knew that one thing never would. how much you loved her.
to hide your blush, you brush past her briskly and step into the steam. you mess with the button to your slacks as she closes the door and walks back over to the shower. finally unclasping your pants, you relive yourself as the water resumes pitter-pattering on the other side of the bathroom.
"thank you.. for letting me in, i mean. that time you made me take a piss outside, as kids, was NOT funny." you scoff at the memory while you finish up. the water turns off and she pokes her head out, holding the translucent door semi-ajar.
"you gotta admit, back then, i never got to win!" she pouts, watching as you rebutton you pants and move to wash your hands. "with you being older, you were always better than me at everything. it was nice to see my big sis so embarassed and humiliated."
"im better than you because im cooler, not because im older" the cool water runs over the back of your hands, befose you lather on a bit of soap. "and what kind of sick and twisty shit did i do in my past life to be cursed with a sadistic lil sis?"
"you and everyone else love me. im the best." you rinse and dry your hands while her string of narcissistic remarks fades to the background. you reach for the doorknob when you come up short due to a resounding thunk.
"i slipped and tried to grab the water.." she sounds meek, an apparent tinge of shme in her voice. you turn to help her stand up, but shes already on her feet.
shes standing there, in the torrential flow of water, with her hand pressed to her back. you stand back taking it all in. the suds dripping off all, even slightly, protruding areas, the pathetic look on her face, the kicked dog aura surrounding her.. its all too much.
for the first time, you realize how fuckable she seems. what a slutty, grabbable body she has, and what a cruel world it is. she's your sister, not your girlfriend. you couldnt possibly think of her like that.. but you are. the thought of being with your own sister makes your pants get a little tighter and your heart beat a little faster.
the tension hangs thick in the air, as she meets your eyes. the door mustve gotten knocked open as she slipped. you were never supposed to see her like this. the blush on her cheeks appears to deepen a shade or two, but you couldnt swear it wasnt your imagination.
"i... im just gonna go.." your voice quivers slightly towards the end of your phrase, betraying how uncomfortable you were. you take a step back slowly, trying to make it seem like its not a big deal that you just realized youre sexually attracted to your own flesh and blood.
"w-wait.. youre not going to stay and ask me if im ok?" the look in her eyes shifts from embaressment to need.. to... longing?
against your better judgement, you stay.. to make sure she doesnt fall again, or because she might be concussed.. or, at least thats what you tell yourself.
"are you okay?" you look over her again and notice a few bruises forming, a couple on her thighs and one on her elbow. something about the purplish blue marks on her soft, even skin stirs something in you as well.
"im fine, mostly rattled is all. it feels like if i move ill fall again." you notice the slight shake of her hands as she clutches at the shelves on either side and before you realize what it means, youre offering to get in with her.
you might be able to pretend that the thoughts you had about her body dont mean youre a bad person, but you know things will be ruined forever if you get in the shower with her. yet, youre already undressing.
youre not sure how things will play out, beimg so close to her while nude, but youre done stripping. clothes hit the floor as you look towards her for confirmation.
"do i even have a choice?" her words sound straight out of poorly made cnc porn.
"its for YOUR safety, dweeb." you mumble before stepping into the shower, and the path of the water, next to her.
"youre not gonna let me fall?" she looks at you with big teary puppydog eyes, pleading for her big sis to keep her safe.
the last of your resolve to be civil shreds, as the newfound desire to fuck your darling sister moves to the forefront of your mind. almost on instinct, your hands wrap around her waist, pulling her warm body into yours.
your, now fully hard, gock presses against her stomach as you sink your teeth into her neck to stiffle a moan. she tenses for a second and then relaxes.
"sis, what are you- no, we cant-" she babbles mindlessly, as you press her against the wall with your body. her physical efforts to put up a fight are miniscule, but she continues to protest verbally. this must feel natural for her, too.
"cmon, we can pretend this never happened, just let me go.." she whines, pressing her hands against your tits, still obviously not resisting. something in the back of your mind clicks and you realizes shes yours for the taking.
you lean more of your weight into her, cutting off her declaration that incest is bad by forcing your tongue into her mouth. a small little whimper of suprise escapes her before shes kissing you back.
somewhere in the haze of pleasure, her arms get thrown around your shoulders and your hands dip low enough to grope her ass.
you seperate the kiss only long enough to say, "m'gonna fuck you now, okay?" looking down to her needy eyes which hungrily stare at your lips as she nods.
"mhmm." she whimpers back, eager to press her lips to yours. she doesnt weigh very much to you as you lift her knee to her chest and raise her ass with your other hand. you gently rub your tip along her sticky slit before slowly burying yourself inside her warm folds.
"fuck, sis" you gasp into her mouth. this feeling.. its better than you ever couldve imagined. her nails dig into your skin slightly as you bottom out. "sis, are you a virgin??"
a small 'yeah' rings in your ears as she squirms in your grasp a bit. you just took your lil sis' virginity. the knot in the pit of your stomach tightens at the realization.
you slowly piston you hips against hers, desperate to get as deep inside her as possible. you notice her squirming get a bit more frantic and you pick up the pace.
her kissing, which wasnt great, degrades into her tongue lolling to the side as she pants into your mouth.
"can you finish inside me?" she squeaks out between thrusts, and thats all it takes to send you crashing over the edge.
you feel your body tense as you slam into her one last time before shooting rope after rope into her waiting womb. the sensation of being stuffed full of sisterdick and warm cum is enough for her too, apparently, because you get to watch her unravel in your arms shortly after.
you turn around to slide down the wall and sit on the floor with her in your lap, both hesitant to move.
afterall, sistercum is valuable, and neither of you are willing to waste a drop <3
