A married couple in their 40s and 30s appears. The husband, unable to have sex, posts on a forum expressing his desire to watch his wife taste another man's thick semen. An older man in his 50s shows up in front of the reluctant wife. Confident in the thickness of his semen, he masturbates and ejaculates a large amount into a clear glass. He repeatedly inserts his semen into the wife's mouth, making her taste his thick cum. The wife's expression gradually changes, and curiosity for this new experience begins to awaken.
