Hi, Zab -- now that is COOL!!! I am only a tiny little bit o' fluff myself (about 97 lbs), but I LOVE to stand on small men and women whenever possible. I love the intensity of the domination when my rug is totally helpless under my feet.
When I am standing on a larger person, I feel like I need to use bondage or at least have the slave completely naked in order to compensate for my own small size. I also am likelier to use boots and/or high heels when trampling a larger "slave."
I have never been to the facesitting section before -- I didn't know what I was missing
Luv and squishing,
