That can really depend on where your relationship is at and what her limits are.

Hmm, some ideas: Cleaning the house naked, doing the grocery shopping in extra high heels, going to do errands without panties, wearing something that itches or rubs next sensitive spots, having clips, clamps, weights, clothespins, etc attached while doing chores, having to request permission to use the toilet, have her jog instead of walk where ever she goes, wear a butt plug while out shopping (start with short periods, work up to longer periods of time), and instead of just having her play with herself 5 times a day make it be in a public restroom (or even more public, again depending on limits).
