Billy, a fresh-faced amateur, can't resist the temptation of his own body, especially when clad in his snug, enticing underwear. He tentatively touches himself, gasping at the sensation of his big, hard cock pressing against the fabric. His stroking becomes more confident, his breaths coming in quick, hot pants. His underwear grows damp with his precum, the scent of his arousal filling the room. Billy's body tenses, his balls drawing up as he nears climax. With a final, desperate stroke, he cums, his load soaking through his underwear, leaving him panting and satisfied.
