Work Text:
Sophie lays on her belly in the living room, propped up on her elbows, eyes fixed on the TV, controller in hand, black stocking-ed feet swinging behind her like inverted pendula. Her face is totally blank, eyes moving subtly to follow the character on the screen. Her jaw works steadily, mindlessly on a piece of gum; occasionally she blows a big pink bubble.
Danae paces aimlessly past the living room a few times to admire her little sister’s butt. To admire her little sister’s whole deal, really. Sophie is nineteen but often gets mistaken for being younger because of her small stature. The obvious jet black dye job, the pigtails, the black metal band T-shirts, to say nothing of the bubble gum seem to say “fifteen year old goth” even though she just finished her freshman year of university. (Danae is very different. Tall, lumpy, pear-shaped, not at all stylish, already twenty-five but gets mistaken for being older because of her general frumpy librarian vibe.)
Danae sidles into the room and settles on the couch, eyes glued to her sister’s thick thighs sticking out from under her baggy T-shirt. (She’s only wearing a long T-shirt and stockings. Normal lounge wear for her.) After a moment, Danae slips onto the floor, leaning her back to the couch, extending her legs parallel to Sophie’s prone form. Waits a bit, pretending to admire her sister’s prowess at Celeste. (Sophie has, in fact, collected all the strawberries, though her friends were never as impressed as she had hoped.) As Sophie makes a frustrated noise after falling on some spikes, Danae slips a little closer, so they’re almost touching. Sophie takes no notice and continues to play.
Slowly, carefully, silently, Danae retracts her legs, shifts so she’s on her knees, scoots slightly forward so shes level with Sophie’s thighs. Hovers a hand over Sophie’s plump bottom. (A plumpness Sophie bemoans, but Danae enjoys. “Ugh, I’m getting fat,” Sophie will complain, and Danae will say, sometimes aloud and sometimes in her head, “No, you’re pleasantly squishy.”)
“I see what you’re doing there,” Sophie says flatly without taking her eyes from the screen. “You’re not fooling anybody.”
“Shh,” Danae murmurs. “You’re supposed to pretend not to notice.”
“You’re about as stealthy as a cow.” Then, under her breath but perfectly audible, “Fat and ugly as one too.”
“Moo,” Danae agrees, and slips a hand under Sophie’s T-shirt to grope her bottom. She grabs one rounded butt cheek, squeezes, pats it affectionately, then moves on to the other. Sophie rolls her eyes but does not otherwise react. Not when Danae gropes her, not when Danae straddles her thighs, not when Danae flips up the hem of her T-shirt to reveal her butt (now only covered by sheer black nylon). When Danae leans down, plants her face right in the center of that round butt, and inhales deeply through her nose, Sophie mutters, “Freak.”
“It’s true,” Danae murmurs, her breath coming a little heavily. She inhales voluptuously again. “I am a freak...” She pulls back enough so she has room to grab Sophie’s stockings and yank a big tear into them, right on the butt. “I’m sorry...”
“Don’t apologize then keep doing it,” Sophie mutters, blowing a bubble discontentedly. “Just stop.”
“I... can’t...” Danae breathes, pressing her face to her sister’s now-bare butt crack and inhaling again. “I’m sorry, Sophe. I can’t resist...” She spreads Sophie’s buttocks with her hands and snakes out her tongue to caress her sister’s little pink rosebud.
Sophie twitches, swallows, promptly dies in her game. Takes a deep, slightly shuddering breath. “Fucking pervert,” she intones, seemingly to herself. Tries the platforming sequence again. Dies again. And again. “Listen, Danny,” she says. “I’m on, like, the super extra hard optional bonus bonus level, okay? Trying to concentrate over here.”
Danae does not seem to hear. Just moans as she slides her tongue deeper into her sister ass.
“So, like... can we do this later?”
Danae pulls back, chest heaving, eyes clouded, gaze fixed on Sophie’s asshole (now gleaming with her own saliva). “I’ll just be a minute...” Danae pants, pulling up her skirt and fumbling with her panties.
“That’s what you always say...” Sophie complains. But she makes no move to resist as her sister pulls out her cock, spits on it industriously, jacks herself off for a moment to spread her saliva over herself, then (with practiced accuracy) spits right onto Sophie’s asshole. Sophie flinches slightly, her whole butt twitching (cutely, Danae thinks), but that’s the whole of her reaction.
Still breathing heavily, Danae leans forward, aiming the bulbous head of her cock between Sophie’s butt cheeks. Sophie keeps her gaze fixed on the TV, the controller buttons clacking quietly in her hands. Danae gives a deep, wanton moan as her cock head slips past Sophie’s sphincter. Sophie gives a little “Mmh,” hardly more than an exhale. She’s stopped chewing her gum.
Now Danae’s mouth is hanging open and she’s drooling slightly as she thoughtlessly humps her sister, relishing the slap of their flesh colliding and the jiggle that runs through Sophie’s rounded bottom with every thrust. Danae’s not particularly long but appreciably thick cock is now disappearing entirely into Sophie, spreading that cute little rosebud wide.
Sophie bites her lip, fights to keep her breathing steady, and dies again on the screen.
Danae was wrong about just being “a minute,” but she doesn’t last more than three before she’s moaning even louder, burying herself to the hilt, letting her eyes roll back, and shooting off deep in Sophie’s ass.
This is gonna be a bitch to clean up, Sophie thinks as her sister’s cock continues to throb inside her. Fuck. Is she still coming?
Finally, Danae slowly, gingerly pulls out, her cock coming free with an audible pop. She gazes down in delight as Sophie’s ass gapes for a moment as if showing off it’s pearly white reward, before slowly closing, then finally emitting a gurgling little cum fart.
Sophie feels herself blushing. Clenches her jaw, gazes fixedly at the screen (where her character has died ten times now on an easy jump. “Fucking perv,” she mumbles through clenched teeth.
“S-sorry...” Danae says. “Sorry... sorry...” She pulls down the hem of Sophie’s shirt to cover her butt, pats it once as if to say “There, like nothing ever happened!” Perhaps realizing the futility of this gesture, she hastily climbs off her sister’s thighs. “Sorry,” she mutters again, and flees to her room, where she jerks herself off to another climax, going over the whole sequence again in her mind and imagining the grip of her sister’s ass around her cock.
Sophie plays her game for another few minutes, feet scissoring back and forth in the air behind her, jaw working her gum again. Dies several times. Realizes she’s not gonna get anything done this session, shuts it off. Drags herself to her feet and pads up the stairs to her own room, feeling her sister’s huge load ooze out of her, soak through her stockings, drip down the back of her thighs. Lays down on her side, slips an almost unwilling hand between her own legs to feel how wet she is. “Fucking perv,” she says again, fingertips finding her own clit.
