Munching the leather gorilla

Going down on an older woman who is ridiculously hairy.
Similar to tasting the fuzzy purse or the bearded beaver.

John: Where were you last night I tried to call you?
Paul: I went down on Rebecca Anderson's mom but it just felt like munching the leather gorilla.
John: Oh yeah I hear it's like a a bearded beaver.
Paul: Nah, bearded beaver is tasty, at least it wasn't a fuzzy purse.
John: Oh man, at least it wasn't a fuzzy pudding purse.
Paul: Yeah, but it stank of asparagus.
John: That tastes chief.
