Brian knows the affair is wrong. He's known from the moment Wendy first undressed in his office. But with her hot, wet tongue in his ear, and her taut, pink nipples straining against his starched white shirt, and with Mick Jagger's strident voice squawking about satisfaction on the tiny transistor radio, Brian's body refuses to obey.Instead of shoving Wendy out the door, he shoves her onto the unmade bed.
