The protagonist, who has enrolled in a school specializing in training massage therapists, finds himself in a school dominated by "squeeze girls," female students who exploit the male students. They were expanding their power through illegal erotic massage battles that took place every night. The protagonist rose up to change this school, but was defeated by the Squeeze Girls, losing his reproductive ability. To add insult to injury, he lost both his hands in an unfortunate accident. However, by chance, he received an illegal body modification from his mad scientist uncle, gaining mechanical hands and a new reproductive organ. Transformed into a sex machine, the protagonist swore to exact a sexy revenge on the Squeeze Girls!
