The perverted father-in-law always spies on his daughter-in-law.

Karen married a Japanese man and moved to Japan. Not really understanding Japanese culture, she did not understand why her father-in-law looked at her with an angry gaze, while her husband did not understand why his father was wasting a woman of her caliber. The situation became definite when her father-in-law witnessed her masturbating alone in the bathroom and decided to help her.
