Your wife had kept putting back the drinks at the bar, and after a while, was quite drunk. One of the guys there saw you trying to help her out to the car and offered to give you some assistance.
Later, as she had your cock in her mouth, and some encouragement from you, he came up behind her and entered her… You’re still not sure if she was totally aware that she had a stranger’s cock in her pussy, but you were enjoying the view.
Get the boys over, and go to town on those whores’ holes.
A gag would shut her up. But sometimes I enjoy hearing a whore’s screams.
