A soapland where beautiful girls only come to work on their risky days is frequented by men who want to impregnate them. The first person new girl Ruka entertains is a customer who has a wife and child but hasn't had sex with his wife in a while. They play in school uniforms and on the mat, and inseminate deep inside her uterus many times! They even have raw sex right after she finds out she's pregnant! Ruka is crazy about the customer and begs for a second pregnancy!
