Alone in his room, a curious and horny young man decides to explore his body's responses. He starts by teasing his sensitive nipples, pinching and rolling them between his fingers. His breath quickens as he moves down, slipping his hand into his pants to grasp his hardening cock. He strokes it slowly, learning its rhythm, before pulling it out to admire it, pre-cum already beading at the tip. He spreads it around with his thumb, lubing up his shaft for a faster, more intense solo session.
