A man was approached by a co-worker at lunch who
invited him out for a few beers after work. The
man said that his wife would never go for it, 
that she does not allow him to go drinking 
with the guys after work. The co-worker suggested
a way to overcome that problem: 

"When you get home tonight, sneak into the house,
slide down under the sheets, gently pull down 
your wife's panties, and give her oral sex. Woman
love it, and believe me, she'll never mention
that you were out late with the boys." 

So the man agreed to try it, and went out and 
enjoyed himself. Late that night he sneaked into
the house, slid down under the sheets, gently 
slid down his wife's panties, and gave her oral
sex. She moaned and groaned with pleasure, but 
after a little while, he reaized he had to take
a leak , so he told her he'd be right back, got
out of bed and walked down the hall to the 
bathroom. When he opened the door and went in,
he was very suprised to see his wife sitting
on the john. 

"How did you get in here?" he asked 

"Shhhh!!!" she replied, "you'll wake-up my 
mother!"
