Bring him to orgasm.
From Create Your Own Story
Suddenly, his penis twitches as the boy lets out a guttural moan. Moments later a rope of cum spurts from the tip of his penis, covering his own neck and chest. His hips begin to buck involuntarily as more cum flies from his penis as you continue stroking, the ejaculation becoming smaller and smaller. Eventually, it finishes, and the boy lies back, his cum-covered chest heaving and panting in exertion.
