Assignments - Well your first one was mental, make the next one physical, and then the one following that mental. Use the Acadamy for ideas, people are posting assignments there all the time.

However before you begin with the task of physical assignments. Do a BDSM activity checklist with her to ensure you know her limitations and interests. This way you remain within her limitation threashold without asking if something you ask her to do is ok or not.

The Academy has an excelent checklist to use for this.
