In the empty gym, a lone male indulges in a private moment of self-pleasure. He starts slowly, feeling the tension in his muscles after a rigorous workout. His hand wraps around his growing erection, stroking it gently at first, then with increasing urgency. He leans back, eyes closed, imagining the touch of a lover. His breath hitches as he feels the familiar surge of pleasure building. He speeds up, his hand a blur, until finally, with a low groan, he finds release, his cum dripping onto the gym floor.
