A 35-year-old housewife named Kohinata Mai, who has an M personality and loves to serve men. Mai, who has a lover in secret from her husband, is not satisfied with regular sex and is said to be interested in SM. Today, she is subjected to tight bondage training, brain-deadening with bondage irrumation, and repeatedly stimulated with an electric massager, a rotor, and a vibrator. When Mai becomes desperate for a penis, she is vigorously fucked with a large penis inserted, in reverse, and in the station bento position, until she is delirious with pleasure, and then she is given a thick load inside her vagina.
