My wife is no lightweight when it comes to sexual adventure. She once agreed to and I arranged a mini gangbang of 4 guys plus myself.
I did tell her I recently found 2 guys on line who were pretty excited at the thought of to playing with her. I showed her their photos, she liked them and told me to set something up and to let the 2 guys know she "can really get into it". And sure enough when the time came she bent over and held onto a kitchen stool so that one guy can ram away in her big beautiful ass, while the second guy started cumming in her mouth. She reaches down to hold his nut sack so that his dick wouldn't slip of of her mouth.
She was exhausted afterwards. I brought her over to the couch. I told her, "You know you're not finished yet" she nodded. "You got some guy's cum in your ass and someone else's cum in your mouth and hair. It's time your pussy is reminded that it's married to this cock.
