Posted this on another lifestyle sub and got no response, maybe it's a better fit here?

Just curious if other people/couples have a "favorite moment" when they are playing with others? That one sight/sound/whatever that just makes you happy and horny as hell in this lifestyle. My hands-down favorite is seeing how happy my wife is when the guy shifts gears and just starts fucking her hard and fast - probably not a great explanation, so here's what I mean:

This last weekend my wife and I were finally in the same place at the same time for the first time in about 4 months. On Saturday night a friend of ours who is recently divorced stopped by for a beer and to complain about life. When he started complaining about not having sex in more than a year, my wife offered to help him out. Honestly by that point we were getting kind of sick of hearing his sad story and wanted him to either snap out of it or go away and let us enjoy some time alone.

Long story short after 30 minutes of awkward conversation the two of them were naked on the couch, after we finally convinced him she really would let him do almost anything he ever wanted. The first 10 or 15 minutes were pretty predictable, he spent A LOT of time playing with her tits, she sucked his dick for a while, he fingered her a lot. Finally, my wife just told him she wanted to fuck. Again, it started out kind of slow, he was definitely out of practice - and then I got to watch my favorite thing about this lifestyle. About 20-30 seconds before guys cum, sometimes there's a visible switch - they quit being awkward about her being married, or whatever else they are hung up on - and just switch into pure animal sex. And when he did that, I looked at my wife and realized just how sexy, slutty, and happy she looked knowing she was finally getting what she wanted all along - fucked hard. I absolutely love watching her at that moment when she's just enjoying being a little slut and how much she loves sex.

Anybody else have a favorite moment?
