Been reading all the posts with great interest. I've also made a list of things I'd like to try whenever we can start punting.
My history is very vanilla in comparison, however I did mange to attend a Lady Marmalade party once. Eight women to six men was a experience I won't forgot. Prior to going I had some hesitation about other cocks on show, but everyone walked around completely naked and no one cared, which was a great for my nerves. The girls were all fit and really into it. I do remember being one of the last still in action with one girl sitting on my face, another bitting my nipples and a third suckling me off.
It's was also the only time I managed five pops in two hours and an experience I'll never forgot.
