Kuroi is a wannabe yaoi manga artist, seeking to help the fledgling manga club with his debut doujin. But, Donbe, a hot gyaru walks in on him drawing and points out that the way he draws dicks is “weak”. That’s because he uses his own as reference. So Donbe decides to let him use her big throbbing dick as reference. Of course, the best way to do that is make him her bitch.
