Reminds me of my friend who asked me to fuck his wife because he couldn't get it up for her.. After our first session, which he filmed, She told him she wanted him to let me fuck her whenever I could.. He agreed but also was so happy that after he watched us fucking on the video he was able to get a boner on and he and his wife were able to have normal sexual relations again. He assured me that I had solved his problem and wanted me to continue fucking her whether he was with us or not.. Honestly,, most times we are all together. lot's of good fun for all..
