If a service of this type would be available, I for one would be a more regular pooner. The downside of pooning is the inevitable expectations and "script" that gets followed making the experience.
I have tried on two occasions to set up something a bit closer to an unscripted encounter. Using an incall service where there were various girls, I made arrangements to pay for the time and then have a few girls join me for a drink in their "waiting room." The role that we were playing is that they were soccer moms and i was a soccer dad and we were at someone's place, waiting to pick up our kids from an out of town game. The conversation was framed in that context and included flirting of the sort that might happen in a real life situation of that sort (in other words, not too overt.) The deal was that one of them would seduce me but I would have no idea which it was.
The experience worked not too badly in that I spent approx 20 minutes having drinks with three women, not knowing which one I was going to be able to have sex with. The interesting part is that I ended up with the one whom, if I had to choose, would have been my least preferred woman both from a looks and personality perspective. However, her roleplay was exceptional, including when we ended up in the bedroom together. Unknown to me, I ended up with an unexpected bonus when one of the other women "walked in on us accidentally" and then decided to join in -- something I had not expected or preplanned.
All in all, this turns out to have been one of my more memorable pooning experience which I credit in part to the fact that it did not follow the standard script that SP encounters seem to. I have tried to set up similar scenarios where a unknown woman will "pick me up" in a strip club and take me home. The challenge with all of these scenarios is that to work, they are time consuming and consequently, very dollar consuming as well when dealing with providers who are used to hourly pay.
