I was watching playboy tv and it was sooooooo funny- he was doing. Handstand eating her out then he somehow did a flip and rolled her over so that he was on the floor still eating her out but they had switched positions. It was hilarious but I'll leave that for the mre flexible of us.
I did it once about 25 years ago when I was single. The girl was a very tiny little thing and I think that's why it worked. The experience was fun, but not good enough to have missed it over the last 25 years. It kind of happened by accident anyway, as we were playing around and me picking her up. I turned her upside down and she started oral on me so I just reciprocated. It wasn't anything planned and we only did it for a few minutes until we moved into a more comfortable position.
