MUDR-133 Aoi Kururugi's father-in-law wants to conceive his son's wife.

⁣The mother of Aoi Kururugi got remarried to a wealthy and powerful man. One day, her new father-in-law comes to her with an outrageous request: Since Mother is no longer able to become pregnant, he wants Aoi to bear his ****.

This demand baffles Aoi because his father-in-law is a spooky old man and she is still a schoolgirl. However, she caves in under pressure and the situation. She didn't anticipate him being so lewd about it.
