There are three female seniors in the manga research club I belong to. I'm the only male member, so it's like a harem! But that's only for a moment. All three of them are unattractive and hang out at my house where I live alone, disturbing my studies every day. As this lifestyle continues, one of the seniors says she wants to draw a picture of a penis. They force me to take off my clothes, and say they want to see the moment I ejaculate, and bully me. I wonder what will happen to my relationship with the seniors from now on...
