Towa, a female college student whose boyfriend has gone abroad to study, has been forced to live an abstinent life. One day, Towa, who is bothered by the moans of the old man living in the trash room next door, goes to complain. However, she is caught and raped by the creepy old man who is addicted to sex! He has sticky sex with her and injects his aphrodisiac semen into her body, forcibly training her to squirt. Even though she should be frustrated, she squirts and gets creampied over and over again... her body and mind are corrupted by the old man.
