Seigo and Miki, who have been married for two years, were trying to conceive by abstaining for a month and releasing the stored sperm, which coincides with the fertile period just before ovulation. Miki’s older sister Mina, who lives in the neighborhood, also wanted to have a child, but due to her husband’s ED and busy work schedule, she is unable to have sex. Mina, who wants to get pregnant before her sister, comes to seduce Seigo on the day her sister and her husband are due to have a child, wearing no bra with her nipples sticking out.
