My horny wife Reina-chan is masturbating while watching SM videos, showing off her open legs in an M shape! Her father-in-law, who has heard about their two years of sexual drought, decides to tame her by binding her wrists and ankles together before using a vibrator and electric massager on her helpless body! She begs him to touch her pussy, so he stuffs a dildo inside and makes her ride it while shoving his hard cock down her throat for a blowjob! He orders her to swallow his cum and make her cum with a vibrator at the same time. As she opens up more and more under his control, she pleads for him to fuck her pussy. He obliges by giving her a creampie filled with his seed that resembles both her husband's and his own DNA! This masochistic training turns my submissive wife into a pleasure-seeking slut who enjoys being dominated during their intense bondage sex. Oh, dear father-in-law... I apologize for having such a perverted wife.
