The film tells the story of a polyamorous teacher Maria Ono and her eager male colleagues. Because she didn't have a boyfriend and her sexual needs were increasing, she came up with a bold idea to solve her problem, which was to seduce her colleagues at school. The private times when there were only two people in the beautiful little office were a good time for her to carry out her lewd plan. In the face of the attraction of a seductive woman who constantly has soliciting actions such as rubbing her chubby buttocks against the opponent's penis, there is no reason why weak colleagues are not easily fascinated.
