This video is an amateur submission sent to an SM magazine. *All names are submission names. [From the submitter] Kikue is my wife's older sister (married with children). I am currently training her as a masochistic slave. In fact, I have been aiming for Kikue since we got married. My wife's family is a business family, so both sisters were raised in a refined environment. They were sisters who aroused my desire to dominate as sadists. My wife developed her as a masochist during her married life. And I got her to seduce Kikue. Kikue was even more of a masochist than my wife. She responded well to urine drinking and bondage play, and her vaginal expansion went well, easily swallowing the vibrator.
