Pin the Tail on the... Ouch Charlie, that hurt!

Of course, I'm talking to a very adult Charlie, who has just invited me over to learn a new game called Pony Play. I've heard the term many times, but really never gave it much thought. I assumed it must be a type of fetish play where a Dom or Masters orders a slave on all fours and rides around on him/her like a pony. Yeah, sounds real fun. Not. However, now, I'm in class getting ready to learn the ropes (NPI - no pun intended). So before anyone starts crawling around on the floor, I'm going to get the schpeil.
