Trampling The Slave Girl Under My Nylon Feet

I know the slave dame loves my feet in nylons - but today shell suffer under these feet! Im trampling all over her skinny little figure and my big feet hurt her a lot as I walk over her stomach and chest! She has to endure my full weight - and Ive even meaner plans for her! Until now I only trampled her chest - but today Ill try to stand on her throat with my full weight for the first time. Shes clearly afraid when she feels my foot sole coming down on her throat - but theres nothing she can do! And it gets even worse for her as I decide to walk over her head as well - and I even keep standing on her head for a short time.
