Akira Shibuya is set to have a special training session with his trainer. The trainer pleads with Akira not to mention the previous incident where he got aroused from being punched and eventually passed out. Akira agrees to keep quiet—but only if he reaches orgasm. This promise seals the trainer's fate. As the session begins, the trainer can't hide his fascination with Akira's uniform, and with each punch to Akira's face, he grows visibly erect. Akira retaliates with fierce blows, knocking the trainer down, then mounts him to deliver relentless face punches, face sitting, and groin strikes while seated on his face. He intensifies the torment by jerking the trainer's cock with boxing gloves while hurling insults like "Disgusting!" The trainer confesses he's always wanted to be bullied by a gyaru girl, which utterly repulses Akira. Continuing the assault, Akira rains down repeated face punches from mount, stomps on the trainer's face and groin—attacks far beyond actual boxing. Can the trainer endure without climaxing? Watch to find out. Recommended for those who enjoy the thrill of being punched with boxing gloves and having their cock mercilessly jerked.
