Discipline: The Hentai Academy vol. 1 (18+ DVD)

Lesson 1:

It felt like heaven when Takure Hayami first transferred to St. Alcadia School with its all-girl dormitory. The babes are luscious and Saori Otokawa, the caretaker, is the hottest of them all. Being extravagantly welcomed by the girls, his expectations for a heavenly school life were huge. But his bubble began to burst when the beautiful, but malicious, Morimote sisters, who actually control the school, try and control Takure when they discover his hidden Ultimate Sex Power.

Lesson 2:

Reona Morimote solicits Takure to join her Social Club. Her only intention is to have his Ultimate Sex Power just for herself. He refuses with all his might, but rumor about his sexual power has spread in the school. Now, aside from the Social Club, the Tennis Swimming and other clubs started soliciting Takure. Irritated, Reona kidnaps and imprisons Takure`s love interest, Saori, to lure Takure into visiting her club.
