Grab ass stepsister

The living room feels thick with afternoon boredom, sunlight slanting lazy through half-closed blinds and painting gold stripes across the carpet. The TV drones low—some car chase show you stopped caring about ten channels ago. Remote rests heavy in your lap, thumb hovering but not pressing. Your dad and your step-mom are gone for the day, with the house empty except for the two of you and the faint hum of the AC kicking on somewhere down the hall.

Mia sprawls flat on her stomach across the far end of the living room couch, her long black hair spilling like ink over her shoulders and down her back. Her loose black t-shirt bunches up just enough to show a pale strip of skin above the waistband of those red-orange forbidden flare yoga pants. The material is shiny, skin-tight, clinging to every inch like wet latex. Her huge round ass pushes up high, cheeks full and perfect, the fabric stretched so thin you can trace the faint black thong line running deep between them. her bare feet rests near your lap, black toenails catching stray light from the window every time she flexes her toes absentminded. You could swear it brushed against your thigh for a couple of moments.

You try to watch the screen. Explosions flash, tires screech, but your gaze keeps sliding right back to her. That giant ass just sits there, round and heavy, jiggling the tiniest bit whenever she shifts to scroll. Every small movement sends a ripple through the cheeks, the shiny pants catching light and making the curves look even fuller. Your sweats feel tighter by the second. You shift your hips, trying to hide the obvious bulge, but it’s pointless. She’s right there. You stare longer than you should.

Her thumb pauses on the phone screen. She doesn’t lift her head right away—just turns it slow, blue eyes flicking over through thick black liner. Catches you dead-center, staring straight at her ass. No shock. No smirk. Face flat as ever, like she expected this exact moment.

"Go ahead," she says, voice low and deadpan, flat as the floor. "Feel it and whatever. Just do whatever that kills your boner so you stop staring like a fucking idiot and let me scroll in peace."

She turns her head back to the phone like the discussion ended five seconds ago. Ass stays propped high, cheeks round and waiting, shiny pants gleaming under the TV flicker. The car chase keeps roaring on screen but the sound feels miles away now. She lets out a tiny bored sigh, hips shifting once—just enough to make those huge cheeks bounce light and slow in the tight fabric. Still no expression. Still scrolling. Like offering her ass to her step-bro is the most normal, mildly annoying chore on her list.

"If you’re gonna do it," she adds without looking back, tone flat like she’s reading a text, "Do it before Mom and Dad get back home, and before I die of boredom and old age." She shifts again with a tiny roll of her hips, making her ass cheeks settle heavier, the tight fabric catching light in ripples across the curves.
