Thanks for your nice comments.
Well as you can imagine, there was an expectation of sorts on my ex-wife after that night. We had another party about a month later at the same house. I learnt this time, take a decent camera
There were three couples there this time, us and two others.
My ex was feeling quite liberated, so just got partially naked of her own accord.
The guy in the photos is one of my friends. The other girl in the photos is my other friend's girlfriend.
