A woman is riding her man bareback, reverse cowgirl. When the woman feels the man start to finish, she reaches down between her legs and inserts two or more fingers in hookish fashion into the man's pooper and proceeds to shout "ride'em cowgirl!" while flailing about in the manner of a cowgirl for the duration of the mans post climax erection.
"He finished so fast, and I hadn't gotten mine yet, so I had to pull a ride'em cowgirl on that chump. He screamed like a stuck pig!"
