My school friends, who were having sex in a bad relationship, ordered me to be their monitor. But I was secretly called upon by her gloomy nature to take her place as their penis, leading to a fulfilling period of frenzied penetration and ejaculation. (Kumiko Sakura DVAJ-686)

As a virgin, I was ordered to act as a monitor for my boyfriend's sex at school, replacing the hotel's rules for having sex with him. I couldn't resist spying, and our eyes met! Oh no, I've been caught… But afterwards, I was called in and told, "Were you spying just now?" and "Let me see your penis too," leading to an unexpected development. She was unhappy that her boyfriend lacked premature ejaculation techniques and was very interested in my erect penis. After being overwhelmed and penetrated, we were perfectly in sync, experiencing multiple orgasms and reaching an unprecedented climax. From then on, the days of secretly having sex after monitoring our sex began.
