A bi boy's curiosity gets the best of him as he locks himself in the bathroom, his thick cock already hard and leaking. He jerks it slowly, savoring the sensation, his mind racing with forbidden thoughts. He wants to be used, to be filled, to be ruined by another man's cock. His strokes become more urgent, his grip tighter, as he fantasizes about a stranger's cum dripping from his ass, marking him as used. His body tenses, his cock throbs, and he ruins himself, his cum splattering across the mirror, a testament to his self-ruination.
