Rinka, a housewife frustrated by her bland sex life with her husband, invites a man she met through a dating app into their home while her husband is away to satisfy her craving. The pleasure of the throat that her husband can't provide makes Rinka tingle, and she repeatedly engages in affairs with this man during her husband's business trips. One day, when she was supposed to have an affair with the man as usual, he drugged Rinka and his friends gang-raped her throat. Eventually, Rinka also gradually screams and goes crazy with orgasm.
