Nozomi Maezono lives happily with her husband, enjoying regular creampie sex and a seemingly perfect marriage. However, behind closed doors, after her husband falls asleep, she is treated like a female dog by her stepson, forced to wear a collar and submit to his every command. She is made to masturbate on demand, brought to orgasm with vibrating toys in humiliating situations, and teased with a remote-controlled vibrator under the dinner table. She is required to perform servile acts, licking from his toes to his asshole, and receives creampie blowjobs until he cums inside her mouth. Fully trained and obedient, Nozomi even lets her stepson perform titty fucks in her marital bed, takes him from behind, and ultimately experiences full incestuous relations, culminating in a facial—depicting an extreme descent into forbidden desire.
