MIAB-583 "Senpai... I'm not feeling anything at all..." Yumi Nijimura, a rental cohabitation partner who contracts a flesh masturbator that can be used for instant sex anytime, and who gets creampied over and over again

Due to an unexpected turn of events, I ended up living with a junior female colleague. She came to me with desperate feelings and I agreed to let her stay with me under certain conditions. I signed a contract with her that allowed me to fuck her whenever and wherever I wanted! She's my fleshy masturbator that I can fuck whenever I want, anywhere in the house. But even though I was fucking her, she said, "I'm not feeling anything," so I decided to make her feel something, and I was also determined to make her pregnant!
