The perfect chairwoman that everyone adores turns out to be a total masochist. He'll enjoy his sweety flirty and super stimulating academy sexlife with her! Anytime, anyplace, his M slave & lover will serve him, her master! She's begging for it!! Nagisa is a childhood friend of his, slightly older than him. She works as the academy as chairwoman and has had feelings for him a long time, but due to her overall excellence as a person, and a beautiful babe, she feels far away. However, he calls her on her birthday and there she gives him a confession. A confession of love. A confession that she is masochist. A confession that she wants to be his sex slave!
