My parents were assigned to work alone and lived alone ... Recently, I live with my classmate's self-proclaimed succubus. Mr. Sakuramachi, a classmate who is sober and unfriendly but popular with boys. I had never talked about it, but if I could get to know each other at the meeting of the committee ... I was attacked on the contrary !? What a joke, I'm a succubus !? Moreover, I settled in my house !! The semen is squeezed out from the morning and I feel very tired, but it feels even better ... With a tongue that seems to be entwined in the morning, I meet secretly in the school during the day and continuously ejaculate in bed at night ── What will happen to my body if I continue to be given such pleasure !? Extreme sexual activity with naughty Sakuramachi!
