Haruna Nogami complains that her husband does not satisfy her, having been sexless for about five years. Feeling lonely, she ended up having a relationship with a younger man she met at a bar. Initially, she regretted her mistake, but over time, her sexual desire and excitement grew, making it impossible to control herself. Later, she had several casual partners but still felt unsatisfied, so this time she volunteered to appear for more stimulation. Ayako Machida's husband is a senior executive at a major corporation. While she lives comfortably without financial worries, she is quite dissatisfied with her sex life. As she ages, her sexual desire increases, while her husband's decreases, a common scenario. Their occasional marital relations always follow the same routine, feeling more like a chore. Unable to suppress her desire for more intense sex, she decided to appear in an AV.
