Sumeragi Ryouko no Bitch na 1 nichi

On the surface, Ryoko Sumeragi seems to be a dedicated teacher at a private academy, but in reality she's a nymphomaniac who loves to have as much sex as possible, from morning till night! Ryoko starts her day by doing naughty things with her brother Akito, who she likes to tease, then it's off to school, where she'll probably fool around with her male colleagues, or even get into some more serious "trouble" all over the school, with students or other teachers.
