A chance encounter in the locker room turns into a mutual masturbation session as two strangers, a man and a woman, find themselves alone and aroused. She watches him, hidden, as he strokes his cock, her own hand slipping under her clothes to mimic his rhythm. He catches her watching, and instead of stopping, he invites her to join. They stand there, two strangers in a public place, their bodies responding to the forbidden touch, their moans echoing in the empty room, as they bring each other to the brink of orgasm with their eyes locked onto each other's hands.
