His Blushing Plaything by Emily Tilton

When she is chosen by a powerful executive to participate in a high-stakes competition waged within her company, twenty-one-year-old Natalie Smith has no idea what to expect. It is only after her hesitation to strip and present herself for a humiliating inspection ends up earning her a painful spanking that Natalie begins to realize how incredibly shameful the event will be for her.
Natalie will be bared and displayed before an attentive audience, and as the contest progresses she will be punished, used, and enjoyed by her stern, handsome partner and sometimes even rival players as well. What truly leaves her blushing, however, is the knowledge that she will not be able to hide her helpless arousal as her quivering virgin body is publicly claimed and mastered.
