Shiratori Academy was once a prestigious all-girls school for young ladies from high-society families. Even after becoming co-ed, most of the female students remain arrogant ojou-samas who act high and mighty toward boys while secretly harboring extremely lewd desires.

The most feared group is the unofficial Otome Club, led by four stunning big-breasted girls: Segawa Reika, Umezawa Rune, Kusuda Nao, and Shinohara Tamaki. They lure targeted boys into their club and toy with them until they’re mentally and physically exhausted.

Ordinary student Todo Shota has no connection to them until he accidentally overhears their shocking secret. The girls immediately capture him and force him to join the Otome Club against his will. What starts as simple membership quickly turns into daily sexual torment as the busty club members use their overflowing bodies and sadistic teasing to play with him endlessly.

From forced crossdressing and blackmail photos to jealous rivalries and intense harem-style encounters, Shota’s school life becomes a bouncing, jiggling festival of giant breasts and non-stop debauchery. Will he survive the Otome Club’s “training,” or will he fall completely into their voluptuous trap?
