You figure to be a real Dominatrix she needs a slave of her own. So to help with that you change her crop whip so that anytime she hits a family member with it they'll turn into a sexy, submissive, horny, masochistic, lesbian who's madly in love with her. The transformation will be under the same rules as the costumes in the fact no one will mind the changes. Also anything they wear or their mistress does to them in public will be seen as acceptable. Lastly you include that the girl knows all of this.
