Kanako has been married to her husband for 14 years. In recent years, their sex life has drastically decreased, and she's been relieving her pent-up sexual frustration through an affair with a college student she met at her part-time job. But lately, that hasn't been enough anymore. Her desire for more intense experiences has grown stronger, and she's started thinking it would be even better to invite her lover over to her house for sex while her husband is away. When she proposed the idea to her boyfriend, he turned her down, but her frantic excitement and eagerness to continue their illicit affair are clearly evident.
