I've been married to Naoki for two years now, and I wanted to have a child as soon as possible, so I researched the most fertile times from the day of ovulation and worked hard to have a baby. - Tonight is that day. - However, Naoki brought his friend Oki, who was nearby on a business trip. - I didn't even notice Mr. Oki's sharp expression. - Then, the next day, I was called by Mr. Oki and raped. - I was creampied even though it was a dangerous day, and after that, Mr. Oki started coming to visit me every month when I was on a business trip. - That time of year is always a "dangerous day"...
