She must have been in another shoot right before this one. When her pants come down she has marks from her buttocks to nearly her knees. And old bruises, someone worked her over pretty well. The tawse may hurt more on the hands but it's so much for fun to deliver it on a naughty girl's bare bum.
Great use of the tawse. My last sub. Kate, hated the tawse on her hands with a passion. She would have taken three to her arse or thighs to one on hands.
