Plumpkin

The opposite of a blumpkin (a guy recieving a blow-job while taking a shit). This is the female version. The girl gets a pleasurable sensation of being eaten out while taking a shit. This can be messy though, and you'll probably get some shit mixed in there.

Shane gave kels a Plumpkin in the McDanks bathroom.
