In a private, dimly lit room, a curious teen boy indulges in a forbidden act. A plastic bottle, his chosen tool, awaits, glistening with lubricant. He leans back, legs spread wide, and guides the bottle's tip to his puckered entrance. His body tightens, then relaxes as he pushes it in, inch by inch, a mix of discomfort and pleasure etched on his face. He grunts, picking up rhythm, fucking himself harder, his cock leaking pre-cum, until he can't hold back any longer, spilling his load all over his stomach and the bottle still buried deep inside him.
