Iori Nanase, who has been married for 7 years, says that she has been sexless for about 3 years due to dissatisfaction with her husband. Recently, she has been driven by an irresistible urge to have sex with someone, but she has a problem: she absolutely doesn't want to have sex with her husband, who is selfish, has no mood, and doesn't give her pleasure. Therefore, she seeks affairs with men other than her husband using an affair site, but her libido is bottomless.
