Ms. Nagasawa (tentative name) can get pregnant with sperm from someone other than her boyfriend who recently proposed (I understand that she doesn't acknowledge it)! - But everyone else is bad, so we can't really fall in love (maybe...) The ultimate immoral document where he dares to summon a woman who will become a married woman on a dangerous day and pours the accumulated sperm into her uterus to ensure fertilization! - After all, the woman's whole body is twitching with excitement...is there any more erotic pleasure than this?
