Pale thighs parted wide on the green couch, her fingers move in slow deliberate circles over her slick pussy. Back arches off the cushions as she bites down on her lower lip, the only sound the wet drag of skin against skin. One hand grips the armrest while the other works faster, her knuckles glistening with her own arousal. Her hips twitch uncontrollably as she fights to keep still, thighs trembling with the effort. The dark room swallows every gasp and moan until nothing exists but the slick slide of her fingers and the wet heat between her legs.
