Etta's Surrender by Carolyn Faulkner

Etta St. James had kept her feelings for her boss, MacDevitt Pierce, under wraps for so long that it was second nature to her. With one little slip, she ended up tumbling – with a white hot behind to boot – into bed with him for one long, steamy night of sensual passion. Then she felt she had to do her best to ignore what had happened. She couldn't bear the thought that giving herself to him like that might have sealed a very lonely fate without him.

Mac was thinking along opposite lines. He wanted more – much more from the woman he could no longer look at and see as just his secretary. He wanted every bit of her that he could get – her total and complete surrender. He intended to see that she did, even if he had to blister her behind to get her to comply.
