The boy, alone and horny, can't resist the call of his giant cock any longer. He strips off his clothes, revealing his enormous, veiny dick standing at attention. He spits into his hand, lubing up his shaft before beginning to stroke. His other hand reaches down, cupping his massive, low-hanging balls, rolling them gently. He picks up the pace, his grip tightening, his breathing ragged. His body tenses, and with a final, shuddering groan, he comes, his cock pulsing as ropes of cum shoot out, painting his stomach and chest.
