True Abnormal Sex: Fortysomething Mother and Child, Part 5: Lewd Mature Mother Reiko Yamaguchi, Moaning and Thrashing as She's Embraced by Her Stepfather and Raped by Her Son
Kiyo (Reiko Yamaguchi)'s husband is on a solo assignment and rarely comes home, while her son stays holed up in his room. Driven by loneliness and isolation, Kiyo indulges in masturbation and begins consulting her father-in-law about household matters, finding encouragement from him. One day, Kiyo vents her dissatisfaction with her husband and is comforted by her gentle father-in-law; the two are drawn into a kiss and end up having a relationship. Her son watches this scene from the hallway. Later, the son confronts Kiyo, berates her, and assaults her. Furthermore, called into her son's room, Kiyo is made to promise "I'll do anything," and ends up performing everything from fellatio to sexual intercourse.
The moderately relaxed posture of a mature woman is excellent. Although she returned after more than a decade, she will soon end her AV appearances. With age, her body lines have taken on a pleasing looseness, and the presence of her large nipples was especially striking in the fuck scenes. However, when the camera zoomed in on her face, the sagging skin around her eyes was unavoidably distracting, leaving me a bit disappointed. If the camerawork had been a little more considerate, she might have come across as more attractive.
