BACJ-063 Lucky tutor

There are three female seniors in the manga research group I belong to. I'm the only male member, so it's a harem! For a short time, I thought, but all three of them are not sexy and live alone, they spend time at my house and interfere with my studies every day. As life like this continued, one of my seniors said he wanted to draw a picture of a dick. I was forced to take off my clothes and said I wanted to see the moment I ejaculated, and I was bullied by three people. I wonder what will happen to my relationship with my seniors...
