I was paired with Yamada-san (Konatsu Kashiwagi) for the school festival committee. My faint hope of getting close to a cute girl vanished quickly... But one night, after I thought the phone call with Yamada-san had ended, I heard moaning from the other end—!? Even though she caught me eavesdropping, we decided to masturbate together...!? I spent my days enjoying a fulfilling masturbation life using Yamada-san's entire body. Then, a popular girl in class (Miyu Aizawa) found out about this relationship...!?
