Way back in the day, when I used to have a Tumblr, I coined the term “mittens” to describe the pattern a butt gets when it’s been hand-spanked in the same spot multiple times and you see… not quite a handprint, but, well, a mitten shape.
(By the way — I gave this spanking, took the picture, and posted it on my old Tumblr. And yes, it was entirely with my hand. I left those marks without using an implement. So if you’re looking for someone who can spank hard, here I am.)
