Cain, a young, lean twink, lounges in his room, his cock already twitching in anticipation. He's clad in snug, white briefs, the fabric tented by his growing erection. He teases his big cock through the thin material, rubbing it gently, his eyes closed, lost in his fantasy. His hand slips inside his underwear, gripping his throbbing dick, stroking it slowly. His breath hitches as he picks up the pace, his ass clenching with each movement. His moans fill the room as he nears his climax, his body tensing, his cock pulsing. With a final grunt, he comes, his cum spilling over his hand and underwear.
