My wife was the tagalong for a friend of hers when they were just out of high school. Her friend was bbc only. They’d travel to another city a couple hours away and my wife would go so her friend wasn’t alone when she met a new guy. Every time her friend would fuck the guy she went to meet and my wife would “hang out” with his buddies in the living room smoking and drinking. I know her well enough to know when smokes and/or drinks she gets horny as fuck and puts out with whoever is around. She finally admitted she did more than hang out and we joke about her taking a bunch of black grenades for her friend
