I'd welcome hearing people's reactions to to this, especially since I'm not at all sure that I've totally figured out my own. My wife's been with a lot of guys, but seeing her with my dad has churned up a big range of different emotions. I'm surprised how much of a turn-on it's been, but I'm also getting feelings of jealousy, which hasn't happened when watching her with other men.
My wife's surprised how hot she's found it to be, even though my dad's by far the oldest guy she's had sex with. They'll probably want to get together again unless I object. They've now been together twice.
Is this totally sick? Have others had this happen? The two of them getting together was my idea, I facilitated and encouraged them, and I've certainly been an active participant.
Here's a pic from video I took.
