Season 1

Bewildered Kaoru wore his new uniform to school. He saw himself in the bathroom mirror and thoughtlessly started masturbating while thinking of the futanari twins, Miyabi and Miaka, to fuel his fantasy. When the twins catch Kaoru in the act, they create a trap to capture him. The sadist twins had humiliating plans to turn Kaoru into their pet.

Kaoru anxiously heads back to the science classroom after the futanari twins, Miyabi and Miaka, demand ¥500,000. While it looked like the twins were no longer angry with Kaoru, this was only a guise to cover their ever escalating devilish discipline. Sometimes mercilessly mean and sometime sweetly salacious, Kaoru cannot resist the twins and submits to their desire driven demands. The twins' plan is to feminize Kaoru, both body and soul. Suddenly, Kaoru's senpai, Kondou-kun, appears who begins to rape Kaoru with the twins' help leaving Kaoru nudging closer and closer to the edge of despair.
