Hyoudou Ibuki: Kanpeki Ibuki Kaichou ga Kousoku Do M!? na Wake(2015)

氷堂伊吹 ~完璧伊吹会長が拘束ドMな理由~

The seemingly strict and disciplined school-council president has a secret. She loves getting roughed up, humiliated and being fucked in the ass. Didn’t see that coming? Well, the new teacher that transferred here certainly did. But she isn’t gonna report her. She just wants something else in return… (These OVA's are based on the erotic novel by Takahane Shin.)
