Danshiryou no Omocha

Due to bad behavior, Taiyou, is sent to a strict all-boys high school. However, due to gossip about his unchanged behavior and loose relationship with women, he has been called out by Sora, the honor student with a kind smile and also the dorm president. Because of Taiyou's rebellious attitude, Sora revealed his devilish sadistic nature and held Taiyou down under the guise of strict discipline. Furthermore, like finding a new toy to play with, he humiliated Taiyou after discovering that Taiyou is a virgin. Although Taiyou was stricken by fear and despair at first, the act gradually turned pleasurable and both of them developed an obsession out of nowhere.
