slick biscuit

The art of enjoying the taste and scent of your womans vagina after sleeping off a long night, or day of intense sex. Applying your mouth and tongue to her womanhood and taking in the flavor of the residue.

We fucked for hours. I woke up first and had to give her a slick biscuit until the flavor was gone and then penetrated her again and busted another nutt, balls deep against her cervix.
