The protagonist, a school nurse, after surviving an accident which left him hanging between life and dead, gained the ability to control the "Life Force" flowing in the human body. Particularly, the energy that is directly related to sexual desire and sensation, the "Lust Life Force," he used his power to toy with the bodies of female students at his school. However, his evil deed did not last long and caused trouble, so he was expelled and went to another school.

At his new school, he still takes pleasure in using his power while keeping it to a minimum to avoid repeating the same mistake. But one day, "If you don't leave the school this semester, I will expose your past," he receives a threatening letter. Suspecting that the sender is "Suou Miyuri," the girl who usually acts harshly toward him, he confronts her to confirm his suspicion, and unleashes the lewdness that he has been suppressing. The Lust Life Force raises the sensation beyond the limits, and while he is able to take Miyuri's virginity and make her go crazy tasting the pleasure of a climax, it turns out she is not the sender of the threatening letter that he had suspected. However, by messing with the girl, he remembers the joy of using his power at its full potential, so rather than blindly looking for the sender, he decides to focus on having fun with the female students he lewdly has his eye on, and begins to spend his remaining time following his desire.
