Before joining Mori Mori Academy, Touno Takashi was a young high school student full of dreams... After the announcement of his father's transfer, he thought he would be transferred to a high school in Tokyo and already imagined himself arm in arm with a young and beautiful girlfriend, strolling through the capital's trendy neighborhoods. Unfortunately, the reality was very different. In Mori Mori, Touno finds himself in a boys' school... lost deep in the Japanese mountains! Although he feels out of place, he is quickly welcomed by Yacchan, who puts him at ease. However, Touno will quickly realize that Mori Mori is not a high school like the others. In this establishment, all students are required to join a club, otherwise they will face sanctions. After thinking about it, he decides to join the photography club, but what he will discover there goes beyond anything he could imagine. Greeted by 5 out-of-control young men having fun with sex toys, Touno will quickly come across his new reality: he is now part of the Yarichin Bitch Club, a sex club that makes other high school students happy. The fiery Tokyo life he dreamed of fades even further for Touno Takashi, a young heterosexual virgin for whom all hell breaks loose
