Based On Another True Event. My Wife Had A Good Friend Who I Will Call "Karen". She And My Wife Had Been

Based on another true event. My wife had a good friend who I will call "Karen". She and my wife had been close friends in college and were in the same sorority. Karen was really attractive and had a fun personality, but her husband was kind of a jerk so we didn't socialize with them much as couples. However, they eventually got divorced and after that Karen went through a bit of a "wild phase" where she dated and (I assume) slept with a lot of guys. She would frequently ask my wife to go drinking and dancing with her which my wife occasionally did. When they would go out my wife would play the role "wing woman" for Karen. At that time my wife knew all about my cuckold fantasies and we had talked about them quite a bit. I always encouraged my wife to have fun and let her know she could do whatever she wanted. She did enjoy meeting, flirting, dancing and on a couple occasions kissing with other guys, but she never went further than that.
