when a woman cannot produce enough or any natural lubricant she melts butter in her pussy, then the man inserts his penis into her pussy, the act of the penis being inserted to the buttered pussy is a butter dunk.... it makes a great treat for oral sex afterwards
My new girlfriend is so kinky, but so old, so when we mess around and I butter dunk the shit out of her!
