Oooohh, endless possibilities...*grins* Just a little brainstorming...

-picking underwear (or lack thereof *grins*) or a certain colour/type of clothing to wear
-control her masturbation/orgasms
-have her wear a piece of jewelry just for you...or ask her to write something on her body...
-how would she handle speech restriction? Being silent for a certain period of time or restricting/requiring the use of words you pick...
-have her practice slave positions while thinking about you...(God, I love that, lol)
-find out what's challenging for her and what's fun to do and then use it with mini tasks or daily routines for her.

From a sub's point of view - I've made the experience that anything that I'm deprived of for a certain time, becomes incredibly valuable and is a great treat when it's granted again...I get the impulse to kiss my Master's feet when he lets me have a cup of coffee, lol.

Just have fun with this and don't shy away from talking to her about it. You don't have to use what she said straight away or in the way she has in mind *grins*...but you'll learn what makes her tick...and what makes her hot.

Also, if you're looking to learn more...the Academy is a cool place to learn about assigning tasks.
