A young man, alone in his room, finds comfort in the growing awareness of his massive cock. With no hands to guide it, his throbbing member stretches and hardens, reaching unprecedented sizes. The fabric of his clothes brushes against his sensitive skin, sending waves of pleasure through him. He can't help but moan as he feels his body tense, and with a final, guttural grunt, his cock pulses, releasing a flood of hot, sticky cum onto his stomach.
