XXX: NEVER ENOUGH

"Doc, I've got this problem" the man says. "My secretary, she loves to
give blow jobs.

Every morning when I get to work I get a blow job. She gives me a
quick one before I leave for lunch.

And before I leave work at the end of the day, she really works me over."

"So what seems to be the problem?" the doctor asked.

"Well, you see, my wife is a nymphomaniac" the man continued.

"I service her every morning when we get up.

I go home for a quick half hour every day at lunchtime and then we
have a marathon session each night before we go to sleep."

"I still don't know what your problem is" said the doctor.

"Well, every time I masturbate, I get these dizzy spells."
