The young lawyer can take no more. He stands, peels off his shirt and tie, and drops his pants and shorts to the floor. He steps around the desk, keeping his eyes on the blonde eating out Mac. He slowly steps behind her, runs his hand up from the small of her back to her left shoulder blade and then around her side cupping the blonde's left breast.
With his right hand he now grabs his fully erect cock by its base and proceeds to rub it back and forth across her ass. He then moves forward and runs the head of his prick up and down between her clit and her rectum, moistening the head of it with her pussy juices. The blonde begins to moan, in harmony with Mac's own gutteral utterances.
"Are you ready for this?, he asks the blonde. And without moving her face from Mac's pussy she mutters in agreement.
