I ignored all of the advice I read, and went for the fantasy anyway. My first punt was a threesome with two well known porn stars charging premium prices.
One the one hand it was fantastic. They were outstanding, and as attractive in the flesh (indeed, probably more so) than on film. There were a few downsides, though. Firstly, it was my first threesome and it turns out I didn't enjoy it as much as I was expecting. Obviously there are certain benefits to having one girl servicing each end simultaneously. But I felt my attention was divided, and I wasn't able to fully concentrate on one girl or the other, which diminished the experience somewhat. Secondly, while I started strongly, my own performance waned throughout the session. Ooops. Nonetheless, definitely an experience I'll repeat. Next time with only one of them, though.
