Rinka, a married woman tormented by sex with her bland husband, brings a man she met on a dating site home while her husband is away and has an affair to soothe her aching crotch. Rinka, numb from the throat pleasure she can't experience with her husband, repeats affairs while her husband is on a business trip. One day, she was supposed to bring a man home and have an affair as usual, but the man gives Rinka a drug and torments her with gang throatfucking with his friends. And Rinka gradually goes wild, screaming and cumming.
