A guy was standing in a bar when a stranger walks in.
After a while they get to talking and at about 10:30 PM the second guy says, "Oh well,I better get home.My wife doesn't like me to stay out during late night."
The first guy replies, "I'll help you out of this. Just do what I say. Go home. Sneak into the bedroom. Pull back the covers. Get down between her legs then lick, lick and lick for about 20 minutes and there will be no complaints in the morning."
The guy agrees to try that and continues drinking with him for two more hours before heading home to give it a try.
When he got home, the house was pitch black. He sneaks upstairs into the bedroom, pulled back the covers and proceeded to lick for 20 minutes. The bed was like a swamp so he decided to wash his face.
As he walked into the bathroom, his wife was sitting on the toilet.
Seeing her he screamed, "WHAT THE HELL ARE YOU DOING IN HERE?!"
"Quiet!", she exclaimed. "You'll wake my mother."
