Mark, a lanky, blonde twink, stands in the bathroom, his eyes darting to the locked door. He's alone, but the thrill of potential discovery makes his heart race. He unbuttons his jeans, pushing them down along with his briefs, revealing his hardening cock. He reaches around behind himself, feeling his smooth, firm ass. His fingers trace the crease, and he moans softly, imagining another man's touch. His hand wraps around his cock, stroking slowly as he continues to explore his own body, lost in his gay fantasies.
