The loud AV sounds coming from next door, where college student Yuuri Adachi lives, become unbearable. Unable to take it anymore, I go to complain, but the man who comes out is completely naked! He drags Yuuri in, his erect cock still in hand, and devours her body as revenge for interrupting his masturbation. Yuuri is terrified, but she's also a strong woman with a powerful libido, constantly masturbating herself. It's not hard to imagine that if Yuuri were to be taken by a sex fiend, she would fall instantly. "This feels so good... I'm going to lose my mind!" Even though she's making excuses, Yuuri keeps going back to the man's place day after day...
