The loud AV sound coming from the room next to female college student Yuuri Adachi... I couldn't bear it anymore and went to complain, but a naked man came out of the room! The man drags Yuuri along with his erect penis, and as a result of her masturbation being interrupted, he devours Yuuri's body. Yuuri was terrified, but no matter what she tried to hide, Yuuri also had a strong sexual desire, and she repeatedly masturbated every day.
