typically the second knuckle of your ring finger after finger fucking a womans tightpuss with your pointer and middle fingers only; results from getting poo from her rectum hole on it
Celeste is great. First she slobbed my knob and gobbled the baby gravy then she licked my rusty fucknuckle clean of her week old ass mayo/ fudge stank combo. AND, I posted it on Youtube for all to see.
