A man went to a bar and picked up a beautiful blond woman. They went back to his apartment and had hours and hours of sex. Afterwords, the man went to the kitchen to get something to drink. He poured himself a glass of milk and then realized that his dick was still hard. Suddenly, he had an idea of how to cool himself off. He stuck his dick inside the glass of milk.
The blond walked in and said, "Oh! I was wondering how you refilled those things!"
