Great question! I would order her to get on her knees( I would provide a pillow) and for your wife to suck my cock between her tits as you watch. Then I would order my wife to suck you as I fuck your wife doggie into you so she can help her. I'd tell her to suck my smooth cock and balls then to squeeze her soapy tits around my cock and make me shoot my thick creamy spunk all over them. I would order her to squeeze those beauties around my cock and to lick the head as it pokes out from between them. I'd feed her my balls while I manhandled those big, soft tits. She would end up messy before we were done. Mmm right now iam dreaming about sliding my cock between those big soapy tits.
