Do-M Joshi to Gakkari Joou-sama

Nakamura is a high school girl with masochist tendencies and she thought she'd found her perfect dominatrix in the tall, beautiful Kumegawa. But it turns out that Kumegawa's personality isn't quite as domineering as she seems. A yuri dom-sub reversal comedy from a genius newcomer!
