Slave Girl Smothered Under My Powerful Feet

I know this submissive slave girl panics easily when she gets smothered and today her face will not only be my foot stool - but my big powerful feet will smother her mercilessly! With my feet pressed firmly on her mouth and nose, she doesnt get the tiniest bit of air and I can enjoy her fear getting stronger and stronger. But shes struggling way too much - so I decide to sit down on her body and then smother her under my feet again! My big feet can cover her little face completely from her chin to her forehead - and she cant get away from them!
