My stepfather I hate is being raped at night...

Akari lives a life of a comfortable marriage with her kind husband. However, Akari had one dissatisfaction: living with her vulgar stepfather. When Akari finds herself tired and falls asleep when her husband is away, the father-in-law takes advantage of the fact that her son is not around, and she worships her firm breasts and deep in the dark, glossy bushes. When he sees his wife's private parts, his stepfather transforms into a beast in heat, and targets a young female who lives under one roof.
