Tsuyoshi Kuroiwa, who combines a strong, well-trained body with a bottomless sexual appetite, makes his debut! This time, he is pitted against "YUJI," a young munchibi who uses his firm ass and youthfulness as weapons, and as the name implies, the battle of the flesh unfolds! YUJI's tantalizing ass doesn't take a bite right away, and he plays and plays with it with the dignity of a champion, until it finally explodes!　He plays and plays and plays with YUJI's intriguing ass, and finally explodes! And I don't mean to exaggerate, but it's really a lot of sperm! It's been a while since I've seen this HD version edited, but I didn't realize how much semen was released! It's a "super" massive release of sperm!
