Miku Nishino, 44 years old, full-time housewife. A mother of one child celebrating her 15th wedding anniversary. She married the husband she dated when she was an office worker, and even now that her child is grown, they love each other at a rate of once a week, but it seems that the content is not satisfying... "I often watch AVs when I have free time during the day, but I've gotten hooked on NTR...". Since being possessed by the pleasure of NTR situations, where she feels pleasure with another man's dick even though she has a loving husband, Miku has become unable to feel stimulation from sex with her husband. "I just want to be fucked up by a stranger once." Not just once, but two or three times, with plenty of guilt towards her husband, she exposes her proud G-cup breasts and indulges in adultery pleasure to the fullest.
