kentucky plug

The Kentucky Plug is a sex position where the man uses his left thumb to finger his partner, and the woman uses her left thumb to finger the mans ass. this is typically preformed with one person sitting on their bottom with their knees up, and the other infront of them squatting down. However, it does not need to be in this position to qualify as a kentucky plug.
