This soapland work is different from ordinary soapland productions. It's not just about unprotected sex; it's a "soapland aimed at conception" where girls manage their health and are only allowed to work on dangerous days. The 45th installment features Yayoi Mizuki. In fact, she previously appeared in just one scene of a "soapland where conception is possible" as part of a manufacturer-sponsored event. That work received high praise, and there were passionate calls for her to reappear, leading to her main role this time. This time, there are more scenes than last time, and there are many impregnation-themed lines from Yayoi, making it packed with highlights such as mat play, body washing, and unprotected sex in sexy underwear.
