A Bit Of A Stretch

Nina slips the new leotard up her thighs and tugs it into place. Penny's eyes linger on the thin fabric stretched tight across her stepdaughter's curves. She tries to look away, but the moment has already caught her. "How does it look?" Nina asks, turning. Penny manages a nod and nothing more. Nina asks for help stretching, making sure nothing catches or tears. Penny steps closer and presses a hand to the small of her back, guiding her forward. The girl's muscles flex under her palm. Another stretch, deeper this time, and Nina parts her thighs wider on command. Penny's breath catches at the heat she feels through the fabric. Nina glances back, eyes bright, and lingers in the pose until the leotard slips slightly between her cheeks. Penny swallows. The next stretch is deliberate—Nina arches, slow and teasing, a soft sound slipping from her throat. Her fingers brush Penny's wrist. Penny's control finally snaps. She pulls Nina back against her and kisses the back of her neck, hands sliding over the leotard. Nina moans and pushes into the touch. They drop to the mat, Nina straddling Penny's thigh as fingers tug the thin strip of fabric aside. Penny fucks her with steady, hungry strokes, sucking marks into soft skin. Nina rides until her legs shake, then buries her face between Penny's thighs and returns the favor until both are spent and slick on the floor.
