Sugimoto and Hikari are childhood friends. Hikari is beautiful and studies well, while Sugimoto is cowardly and useless. Even though he liked Hikari since he was young, he didn't dare confess. The only time Sugimoto felt brave was when he signed up for the karate club, which Hikari was a part of. But because he did not like to exercise much, Sugimoto quickly fell behind compared to other members. They began to bully him, and each time Hikari appeared to rescue him. Because of this, the president began to feel dissatisfied. One time, he called Hikari into the tool warehouse to talk. Taking the opportunity to have only the two of them, he played a cruel trick on her. He threatened to tell everyone if she did not listen. And from then on, Hikari became his toy. He even let the other members fuck her. Although he always excluded Sugimoto from the "game", he accidentally knew about this and always secretly watched. Although he wanted to save Hikari, Sugimoto could not control himself. The president also discovered that he was secretly peeping. He immediately brought him closer to closely observe their lewd games with Hikari. But Sugimoto felt extremely aroused, he quickly became erect, and when asked if he wanted to participate, he quickly agreed and joined them, together prolonging Hikari's nightmare...! !!
