"Senior...I...I feel nothing at all..." Yumi Nijimura, who has a contract with a junior for sexual masturbation that allows her to be penetrated at any time, and who gets pregnant after multiple ejaculations in a rented apartment, is MIAB-583.

For some reason, I started living with a younger woman. Because she came to me for counseling with genuine feelings, I conditionally allowed her to stay. I signed a contract with her that we could have sex anytime, anywhere! I could masturbate whenever I wanted to have sex at home. But even when we were having sex, she would say, "I... don't feel anything," and I was determined to make her feel it, and I was determined to get her pregnant!
