A Bit Of A Stretch

Nina slides the new leotard up her thighs and it hugs her ass like it was painted on. Penny catches herself staring, feels her pulse spike, and tells herself it’s just fabric. Nina turns around, all innocent, “Can you help me stretch so this thing doesn’t split on me?” Penny hesitates, mouth suddenly dry, but she nods. She grabs Nina’s ankle, lifts, watches the thin nylon stretch tight across her stepdaughter’s crotch. Heat crawls up Penny’s neck. Every slow count makes Nina’s body open wider, and Penny’s breath keeps catching. Nina notices the extra squeeze in Penny’s grip and the way her eyes are glued lower than they should be. She smirks, twists her hips just a bit and pushes deeper into the stretch, rolling her spine so the leotard rides even higher up her crack. “Like this?” Nina asks, voice all sugar, then she drops into a split and leans forward until her chest presses the mat, ass up, leotard wedged tight. Penny’s hand slips, lands on bare thigh, and Nina rocks once, deliberately, giving her a show. Penny swallows a moan, grabs Nina’s hips instead, tries to hold her steady, but Nina grinds back against that grip and suddenly both of them are breathing like they just finished a round. “Guess the leotard’s fine,” Nina says, then she sits back, palms Penny’s tits through her tank top, thumbs circling hard nipples. Penny’s last shred of restraint snaps. She yanks the straps off Nina’s shoulders, tongue already on her collarbone. They hit the floor tangled—Nina’s mouth on Penny’s neck, Penny’s fingers shoving the crotch of the leotard aside to find her wet. Nina bucks, bites her shoulder, greedy. Penny spreads her open, rides two fingers deep and fast while Nina works her tongue down Penny’s stomach, finds her clit, sucks like she’s been waiting. The mat creaks under them, moans echoing, both of them slick and filthy until Penny comes with a growl and drags Nina up for a messy kiss, tasting herself, already reaching for round two.
