A University of Michigan Professor was giving a lecture to his first year medical students when he sensed they were becomming bored.
In an attempt to liven things up a bit, he looked around the class and selected an attractive young girl by the name of Melissa.

Melissa he queried. ...do you know what your asshole is doing, while you are having an orgasm ?
The class suddenly fell silent, only a few nervous giggles could be detected around the room.

Melissa thought for a moment before answering with a smirk.
Probably out hunting with his friends.

Your story reminded me of another.........

The wife and I had just finished making love..... Out of breath and sweating, I asked her.... "So did ya, ya know" She said "Did I what". I said "Ya know......" She said "Did I have an orgasm ?" "Yea" I said. She replied that she in fact had !!!!  AND, being a man I had to know..... "So, what exactly was I doing when you had your orgasm?" (GRIN)..... She thought for a moment and said "I think you were in the kitchen getting a beer" !!!!!!!!!

You 2 are very funny! LOL! Thanks for sharing.
