All Tied Up: Ann Summers Short Story 16 (Unabridged‪)‬

Donna's boss Hugh Lancing is a bully, pure and simple. When Donna attends a performance review and is subject to his whip-cracking ways she decides she needs to make a stand.
Calling a meeting after everyone has left for home, Donna brings out her inner dominatrix and shows Hugh who really is the boss - but not without having a little fun of her own.
