JUR-255 I met my classmate Miyu, who used to treat me like a dog, at the personal gym... I got her to beg for a creampie after a revenge aphrodisiac training session.

Yamaguchi runs a personal gym at his home. His work was going smoothly, but he still carries the trauma of being bullied in his school days. The main culprit was a classmate named Miyu, who hid his belongings and treated him like a dog. Just when he was hoping to get revenge one day, Miyu comes to Yamaguchi's gym. Miyu doesn't realize for a second that the instructor in front of her is Yamaguchi. Even though Yamaguchi is angry at Miyu's happiness after getting married, he puts aphrodisiacs in everything Miyu puts in her mouth. And from that day on, he begins his revenge and his aphrodisiac training to reach the peak...
