Riding the Pony Express 

The stage when you masturbate, so that you are at the highest peek of satisfaction, you move your pelvis in a back-and-forth like you are riding a horse.

Last night, I was riding the pony express. It felt so good. Until, that is, my friend barged in on me and forced me to dismount.
