A man gets home from work. He'd barely gotten in the door before his blond girlfriend greeted him with a passionate kiss. Then she pulled him into the bedroom, pushed him down on the bed, unzipped his fly, and began to give him a fantastic blow job.
Not wanting to interrupt her, he waits until he has gotten off in a mighty explosion, which she slurps up eagerly and swallows.
He stares fondly at her, then asks, "OK dear! What did you do to the car THIS time?"
