BACJ-063 Lewd schoolgirls fuck young tutor

There are three senior ladies in the manga research group I belong to. I am the only male member, so it's like a harem! For a short amount of time, I thought, but none of them are attractive and they live alone, spending time at my house and hindering my studies every day. As this kind of life continued, a senior of mine said he wanted to draw a picture of a pervert. I was forced to undress and said I wanted to see the moment I ejaculated, and I was bullied by the three of them. I wonder what will happen to my relationship with the seniors...
