In the quiet of his room, Saitama, the humble hero of City Z, can't resist the allure of his own body. His powerful hands, capable of defeating foes with a single punch, now stroke his massive cock. The anime hero's face contorts in pleasure as he lubes up, his grip tight, his rhythm steady. He grunts, his body tensing as he nears climax, his fist a blur. Finally, with a cry, he comes, his seed spurting out, coating his hand and stomach.
