The horny muscle god, alone in his lair, can't resist the temptation any longer. His cock, a monster of flesh, tents his shorts, demanding freedom. He shucks them off, revealing his throbbing member, already leaking pre-cum. He spits in his hand, lubing up, and begins to stroke. His other hand cups his heavy balls, massaging them gently. He groans, his strokes becoming more aggressive, more urgent. His body tenses, his abs contract, and with a final, powerful stroke, he erupts, his hot, sticky cum splattering onto his abs and chest, marking his territory.
