I'm sure her husband was hand signaling his buddy to fuck her in the mouth like a whore before feeding her his cum load. That's what I used to do on the nights we planned for my ex-wife to have her night of all men. Usually 4 or 5 guys including me. She made awesome videos with no one directing.
Such a sexy wife. What a lovely lady. I've seen my ex do that so many times. She was almost always ready to take care of whatever cock was presented to her.
