“d-don’t, big sis,” he stutters, backing up hastily, tripping over his own feet, “I’m sorry, I didn’t mean to—“
big sis giggles and scoops him up, his burning face pressed tight to her big, soft boobs
pressed so tight he can hardly breathe, and no matter how much he flails and squeaks, she just squeezes him tighter, til he’s lightheaded and dizzy
“please, big sis, d-don’t,” he begs weakly, tears leaking down his face as he gasps for air
big sis just keeps giggling and squeezing him til everything’s spinning
“shhh, lil bro,” she soothes, petting his head, snuggling him down tight between her tits, face smothered against her skin, “it’s gonna okay, I know why you were watching, so just let big sis take care of you~”
lil bro scrabbles at her skin, but big sis just shoves him down onto the bed behind him and crawls on top, pinning him to the mattress with her bigger weight
her lap settles over his, hot through her panties, and big sis says, “stop struggling, sweetie, big sis is just trying to help~”
“please, sis, let me go,” he pleads, small voice hoarse
her slap across his face is vicious, and the second one even more, so hard he hiccups and goes silent, staring up at her with wet eyes and bright red cheeks
“never, lil brother,” she promises sweetly, bending down to kiss the tip of his nose, and slaps him again, so hard he tastes metal, “never, ever, ever; you’re all mine forever~”
he doesn’t fight this time when she climbs off his lap and forces his legs apart, wide enough to kneel between them
she wraps her hands around his ankles and shoves them up towards his chest, yanking his body down with the force of the motion, his bottom scooting and lifting
big sis nudges her knees under his hips, holding him curled up on himself, buttcheeks on her thighs, privates flopped up against his belly, his hole exposed to the cool air
he shivers, and big sis giggles again
“hold your ankles, and don’t let go, okay, sweetie?” big sis asks, squeezing them hard before letting go and reaching down, putting his hands where hers had been
“don’t let go, seriously—I don’t wanna have to tie you down, okay?
making him hold himself there, open for her, obedient
her hands run down the backs of his thighs, nails scratching lightly
“please,” he begs, one last, desperate time, helpless tears leaking out his eyes
she meets his gaze, holds it, pins him with it
shakes her head, frowning, disappointed in him
“I’m gonna have to punish you for struggling so much, lil brother~”
the slap of her hand over his ass is sharp enough to make him cry out, whole body jerking
the next two are harder, and then harder still
and then she starts pinching, grabbing bits of his skin between her fingers and twisting til it bruises
he screams each time, her fingers nipping viciously at his thighs, his ass, his belly
covering him in tiny bruises
when he can see her through his tears, she’s grinning, delighted with her efforts and his agony
then she’s slapping his ass again, each loud crack driving a wail from his chest
(he never lets go of his ankles; he has had her make good on her threat to tie him down before, and it got so much worse than when he’s a good boy for her)
when he’s a shuddering, weeping mess, she starts petting him
stroking his thighs, rubbing his ass, massaging the flesh she’d just brutalized, smiling down at him the whole time she squeezes the sore flesh
he sobs helplessly, clutching his ankles, as every bit of skin exposed to her is slapped, pinched, and kneaded
when she’s rubbed his bruises thoroughly, she says, “suck my fingers, lil bro~” and shoving two fingers past his lips, down his throat
(he obeys, because the time he didn’t, she just shrugged and shoved them into his asshole dry and fingered him while he screamed)
she enjoys fingering his throat til he gags, then a little more
eventually, she pulls her slick fingers back and slides them between his bruised cheeks, over his hole, making him tremble
“relax, lil bro,” she purrs, rubbing at his rim, slicking it up, “it only hurts because you keep fighting me~”
he whines, low in his throat, doglike, as one of her fingers pushes inside him
“sisterrrr,” he sobs, clenching down around the digit, trying uselessly to push it out even as she buries it to the knuckle
“shhh, be a good boy,” she shushes, using her second finger to rub at his rim while the first one bends gently inside him, “just be good and let big sis milk you, sweetie~”
he drops his head back against the sheets and moans as her finger hits the special spot inside him, rubbing sweetly against it
“there you go, baby,” she praises, fingertip massaging at the spot inside him til his whole body starts to clench and spangle
“please,” he begs again, but this time, they both know he doesn’t mean *stop*
she beams down at him, then adds the second finger
he chokes and sobs at the sensation, the way it burns and spasms, like his guts are gonna turn themselves inside out
it makes his cock twitch against his belly, and a lil pearl of liquid drips out against his skin
big sis licks her lips as she watches the droplet seep into his skin
“see, sweetie, aren’t you glad big sis caught you watching her get undressed?” she teases, pressing both fingertips against that spot inside now, making him see stars
“y-yessss, sisterrr,” he gasps out, eyes squeezing shut around tears as something in his belly starts to coil tighter, like he has to pee, or like he’s being tickled for too long
“just relax, don’t try to hold it in, big sis is gonna help you~”
her fingers rub insistently inside him, squeezing and massaging, and her thumb starts to brush up, towards his cock, over the soft skin in between his hole and his balls, pressing down, like she’s holding the spot inside him between her thumb and fingers
he wails helplessly and shudders all over as wetness begins to dribble down from his cock onto his belly
“there you go, give big sis all your milkies~” she coos, reaching down with her other hand to pet his cock gently
it leaks against her fingertips, and she smears the liquid into his bruised skin adoringly, caressing it into his belly, his hips, his thighs, the skin of his cock, all while milking more from him
“time to clean up the mess you made, sweetie,” she says, finally, a lifetime later, when his cock has stopped dripping and begun to ache deeply, as she pulls her fingers out of his quivering hole
“m-mess?” he asks, lowering his shaky legs to either side of his lap, confused—she’s already rubbed all his milk into his skin
“between big sister’s legs,” she explains sweetly, giggling and pointing to where her panties are soaked through and dark with her wetness
he doesn’t fight when she strips the scrap of clothing off and crawls up the bed to kneel over his face
her pussy is creamy and tart, slick and hot against his tongue
she shouts and grabs his thighs whenever he does well, digging her fingers into her bruises and squeezing as she cums, her pussy grinding down against his face til he can’t breathe
it goes on forever, his lips and tongue surging against her until his jaw aches and long after, til all he can do is stick his tongue out numbly and let her hump his face til she cums again while he tries to gasp enough air to stay conscious
eventually, she flops over him limply, pussy pressed against his chin, and kisses his cock
kisses it and licks it and suckles at the tip til it’s hard in her mouth, and then she swallows him down, humping his chin lazily as she squeezes him inside her throat
her fingers brush at his hole again, and he cums hard down her throat
she swallows, and keeps swallowing, and keeps suckling gently, licking at his overstimulated cock until he’s sobbing into her pussy
“no more, please stop, please, I was good, I was goo-ood,” he wails, voice cracking in the middle of the last word
she ignores him, keeps suckling at his soft cock, and he squeals miserably as she pushes a dry finger back into his abused hole
“stooooppp, please, big sis, *please*, I can’t take anymore,” he sobs, even as her fingers curl against the special spot inside him and make his hips buck, soft cock shoving against her tongue
she hums happily around his cock, sucking a little harder, her pussy leaking against his face as he begs
“it hurts, it *hurts*—I don’t wanna, please—I’ll lick you more, as much as you want, just stopppp,” he cries, trying to keep his body from jerking too hard
(the last time he’d accidentally kicked her off, she’d put stuff down his peehole til he passed out, and he can’t, he can’t again)
she ignores him, fingering his hole and suckling his soft cock, humming soothingly occasionally, humping his chin gently
she cums a couple times while she plays with him that way, enough that his face and neck are smeared with her juices
she stretches his hole on a second finger, too dry this time, too painful
his orgasm startles him, ripping through him as hard and sudden and painful as lightning, making him arc off the bed with a shout, soft cock twitching and leaking just a few drops onto her tongue
she giggles around him, but still doesn’t pull off, and the searing, inexorable pull of her mouth on his aching cock tugs him into unconsciousness
