Don't wake Mother

A man comes home drunk one night and so he doesn't get into too much trouble he decides to orally satisfy his wife. He goes under the covers and does the deed.

Afterwards, he decides to wash the unpleasant taste from his mouth and goes to the bathroom. Sitting on the toilet seat is his wife.

"How the hell did you beat me into the bathroom?" he asks amazed.

"SHHHH!" she replied "Be quiet, you'll wake mother. She's spending the night!"
