doorknob

A couple was in the bathroom getting ready to go to work when the husband looked at his wife and said, "I gotta have you!"
He backed her up against the bathroom door, pulled down her panties and nailed her.
When he finished he started putting his clothes back on and saw his wife still writhing around against the door and he asked, "What's wrong honey? Didn't you come? Do you want more?"
His wife said, "No, no, it's not that. I'm just trying to get the doorknob out of my ass.
