Couple Exchange Club Hikari Aozora, a lewd married woman who gets addicted to sex with other people's husbands to relieve her sexlessness
One day, Hikari, who is troubled by the lack of sex between her husband and her husband, suggests that she register for a ``couple exchange club.'' She vehemently opposes a suspicious organization that she is not used to hearing about, but her husband persuades her and she gives in. She immediately decided to have sex with a certain couple. At first, she rejects Hikari, but she becomes addicted to the pleasure that her husband cannot feel... A slutty married woman loses her mind and drowns in sex.
