As I found out quite quickly, Andrea is highly ticklish, especially when that tickling comes from the small head of the purple shafted riding crop. There was a softer side to the crop, along with the harder side (which was actually cropping her feet) she seemed to actually crave having her feet slapped with the crop head, instead of being tickled by that same crop.
Andrea, really did her best to stay still, but as you will see during the scene, she was all over the floor. Even being trussed up like she was, Andrea still pulled and struggled for all her worth. It was during this time that I found her trying her best to protect her sensitive underarms, and she was also doing all that she could do to keep her feet safe.
Andrea, was unprepared for what I had in store for her, which was using two crops together, in this case I used the longer headed silver shafted crop upon her feet, while the purple one continued to move along her underarms.
