In the cramped, dimly lit changing room, Jonathan's heart races as he locks the door behind him. His eyes meet his reflection in the mirror, and he can't resist the urge any longer. He strips down, letting his pants pool around his ankles as he grips his hard cock. He works it slowly, his other hand teasing his ass, pushing a finger inside as he picks up the pace. The sound of his heavy breathing fills the room as he fucks his own hand, his cock leaking pre-cum onto the floor. He's close, so close, and with a final, desperate stroke, he cums hard, his hot load splattering across the mirror, leaving a sticky, shameful reminder of his forbidden pleasure.
