Turn her into a maid

"Helena, go to the costume store and find the frilliest French maid costume they have with the poofiest and shortest skirt and purchase it along with some five-inch heels. Wear this outfit home. When you are in this costume, you will act incredibly shy and submissive curtsying to every guy you see and having a deep desire to please any and every man, but especially me. You will become turned on just from doing what I tell you to and suddenly become obsessed with showing off your cute butt to men everywhere by bending over in front of them, flipping your skirt up right as you pass them, or however else you see fit. Showing off your butt is your favorite thing to do. Be sure to post many pics of your cute butt on the internet too. Come back here afterwards and I'll have more orders for you. Now go."
