Elevator

Ben encountered an unknown woman in the elevator of his apartment. She hit the emergency stop button, pressed Ben against the door sexually, and asked if he wanted her body. Ben, thinking this was a proposition, said yes, but was shocked when his body started to melt and begin to slide over onto this woman's body. Within a few moments, he was alone in the elevator, and he was her! He felt his crotch to confirm the impossible. A loud buzz sounded, because the elevator had been stopped too long. He depressed the stop button to continue the elevator's trip, but when he got to his apartment, he realized he no longer had he's old keys now that he was in this new body. He began looking for identification of who he know was, where she lived, and any other details.
