Nanami has a problem. She has never been able to control her sexual desires, and she thinks about lewd things. She thinks she will be happy if she gets married. However, her compatibility with her husband is awful. He has erectile dysfunction, and his penis won't get hard at all, so their relationship is over. However, Nanami wants to have a child, so she heads to a luxury hotel for her husband. There she finds a single man with a big cock who has been storing up his sperm for a month. On her ovulation day, she begs him to get pregnant. She can't stop getting excited by his big cock, which is different from her husband's. She impregnates him as much as she wants with her voluptuous body with a 100cm J-cup bust.
