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.

When one person backs up to another person butt cheeks to butt cheeks and farts, thus transferring the package. This can be done clothed or non clothed.
My wife told me not to Dutch oven her again so now I wait till she is in bed and I slide ass to ass and pony express (fart) her.
