A Bit Of A Stretch

Nina's new leotard clings tight across her tits like it was painted on. Penny watches her stepdaughter twist in front of the mirror and feels a rush straight between her legs. The fabric cups Nina's big, natural breasts perfectly, nipples already pushing little dents through the thin cloth. Nina spins and grins. "Can you spot me on my stretches? Don't want the thing riding up or tearing." Penny hesitates, but her hands are already reaching out. She grips Nina's hips, feels the heat through the spandex. Nina leans forward into a deep split and her ass presses back against Penny's crotch. Penny bites her lip. Every new pose makes the leotard stretch thinner over Nina's body until the outline of her pussy is impossible to miss. Penny's fingers keep sliding lower. Nina notices and gives her stepmom a sly smile, spreading her legs wider on purpose. The next stretch has Nina bent over, palms flat on the floor, legs straight. Penny stands behind her, supposedly keeping her steady, but her thumbs are rubbing slow circles on Nina's inner thighs. Nina rocks her hips a little, testing how far Penny will go. Penny groans under her breath. Her hand slides up, cups Nina's breast through the leotard, thumb flicking the hard nipple. Nina gasps, then laughs low and dirty. "Told you it was a tight fit." That does it. Penny spins Nina around, yanks the crotch of the leotard aside, and slides two fingers straight into her stepdaughter's slick cunt. Nina moans loud, grabs Penny's wrist, pushes those fingers deeper. They stumble onto the mat, Penny on her back, Nina straddling her face while Penny tongues her through the stretched fabric. Nina grinds down, tits bouncing, until Penny rips the leotard open at the seam and buries her mouth on that bare, dripping pussy. Nina rides her stepmom's tongue until her legs shake, then spins around so she can finger Penny back. The two of them end up tangled on the floor, sweating, panting, the torn leotard hanging off Nina's shoulders while Penny's fingers pump in and out of her until both of them come hard and loud.
