After many hours of extremely acrobatic and exhausting sex with a blonde he had just picked up, a man goes into the kitchen for some food to replenish his just spent energy.

He pours himself a glass of milkand right before drinking it, he realizes his manhood is still pretty hot,so he sticks it in the glass to cool it off. \

Just then the blondewalks in and says, "Oh, I always wondered how you refilled those."
