Your pretty wife can't help but flirt with your friend, and maybe more...?
Well good job about not making this humiliation for the guy and even making it possible for two women scenario
I love that they left it open so you can make it a female friend. not really a Cuckold, so the fact you don't have to be locked in on one path is a huge plus for me.
This one was fun and adapted pretty well to a twist I threw in and pulled in a twist of her own. Of course, YMMV.
