Sumire Sumire a comfortable married life with her kind husband. However, there is one thing that displeases Sumire. She lives with her vulgar father-in-law. She is fed up with the constant harassment and insensitivity she receives. One day, when her husband is not around, her father-in-law finds Sumire asleep and takes advantage of the fact that his son is not around to push aside her underwear and devour her genitals, which smell of female and sweat. Having gotten a taste for this, his father-in-law rapes Sumire as he pleases almost every day, treating her like a sex slave.
