While a woman is being fisted she engages her kegels, stands up and spins around in a circle until she releases the fister, flinging him across in the manner of a shotput.
-Holy crap man! I'm never going to fist a bitch again.
-What do you mean?
-I was fisting my girl and she got pissed.
-So what happened then?
-So she gets pissed and she fuckin' shotputs me across the room!
-Harsh, dude, I hope you learned your lesson.
