When a person doesn't shit for days and takes a bunch of laxitives an hour before anal intercourse. When the giver is about to climax, the receiver, having held it in for the entirety of the sexual act finally releases their bowels all over the penis of the giver. The pumping action acts as a suction pumping all the shit out of their ass not unlike an oil pump on a rig. Usually done as a retaliation to unwanted anal entry.

During intercourse, when a man is ready to cum, he thrusts his cock deep inside the woman and holds it there while he cums, not moving. As soon as he is done, he continues pumping and his cock spasms a second time.
Last night, when John was having sex with his wife, he held his cock still when he came. As soon as the jism stopped, he continued pumping with his cock spasming again, doing a double pumper.
