In the dimly lit gym, a lone man indulges in a forbidden pleasure. His hands roam his body, tracing the outlines of his muscles, before reaching his throbbing cock. He strokes it eagerly, the sound of his wet palm meeting his shaft echoing in the empty room. His breath hitches as his pace quickens, his grip tightening. A bead of pre-cum forms at the tip, and with a final grunt, he releases, his load painting the gym floor.
