This has always been something that gets me fired up as well.  I once had a session with two ladies that set up a pole and the whole situation.  They both danced, took turns grinding, and one went down on my while the other undressed in front of me (very hot).  Great topic as far as I am concerned.  There is something about a lady standing behind me, reaching around and holding my cock, then whispering dirty thoughts in my ear while another is sucking on me.  Yes, this one is scorched in my memory!
