When I was about 4 years old, my uncle and my aunt visited us. They brought me a painting kit as a gift. Somehow it turned out that I start playing with their feet. My uncle wasn't ticklish, but my aunt was. Yeah, it was the point of no return.
But really I don't know why exactly I wanted to tickle them at that moment.
Btw, I don't like stocks, bondage, torture and other "hardcore" stuff. I'm a fan of a little softcore things, but I really love it when nice girl tries not to laugh when I tickle her. She looks so cute at this moment. And when she enjoys it, I feel even better.
I like videos like "distracting her with tickling" cuz they are warm, cozy and... natural, I think. Real emotions, true feelings, you know.
And yeah, ofc, I like videos where girl reads aloud/dubbing something/just says when someone tickles her feet.
For me it's like an erotic game, a very gentle way to dominate.
So if you think you're childish and cringe, just shut up and read my confession again.
I hope this post will help you find out the truth, or at least help you gather the statistics you need for any reflection or research.
