Nikki always played a character, and usually convinced us that the character didn't really deserve to be spanked, even if they did. That along with that beautiful body, particularly great legs and ass, always made her a pleasure to watch.
I like her humiliating punishment position, exposed completly naked to his greedy eyes, with her hands on the wall, on tiptoe and streched out naked ass, while he plays with the cane at her beautiful down swinging tits, before she feels the cane on her bare ass.
