The boy, alone on the couch, can't resist the urge any longer. He unzips his pants, letting his hard, throbbing cock spring free. He starts to stroke it, his eyes fluttering closed as he imagines the dirtiest things. His hand moves faster, his breathing ragged, and then with a loud groan, he's cumming, his cock pulsing as it shoots stream after stream of jizz onto his stomach and the couch, leaving a sticky, cum-filled mess behind.
