When I was a kid I had a babysitter that would always step on me, why?

That seemed to be one of her favorite things to do. I was 6 years old and loved lying on the floor on my stomach watching TV and if she happened to be walking through my way she'd intentionally step on my back and giggle, not really applying any pressure or anything. A few times I would be lying on my back and she'd even step on my chest/stomach, again just smiling and saying something like "I could squish you like a bug" ha ha...

She was a pretty tall girl, she was 16 and she was at least 5'10...maybe even 6'0 and I think her shoe size was a 10 so her foot took up about my whole entire torso. But I'm curious why do you think she liked stepping on me so much? I remember liking it too for some reason. Still it was really something to look up at a giggling teen girl when you're at her mercy.

I wish I can track her down so I could ask her about it. She was actually pretty cool. Sometimes she would let me stay up past my bedtime and at least twice ordered us pizza.

Note: Yes I do have somewhat of a mild foot fetish and I can no doubt trace it to this, but this has nothing to do with my question.
