During anal intercourse you pull out very quickly and pour a half gallon of milk inside of the female. You then proceed to get a straw and enjoy some ice cold butt milk. For chocolate milk have the female defecate and stir the milk in.
So I was railing Katie G. and I pulled out, poured in some 2%, and had a delicious glass of Butt Milk.
