Daliah is relaxing n the sofa, her foot-slave crawls in the scene directly to her feet.
He thinks it's a good oportunity for sniffing her nyloned feet and toes, without disturbing her relax.
But she feels something at her feet, no it's not an animal or so! It's her pervert feet slave! He needs a lesson!
She shoves him to the ground, now she's over him he is at her mercy.
After some teasing his face with her foot, she steps fullweight on his chest and does a step on his face.
Now you can sniff! Under fullweight pressure!
A face is a perfect standing platform and the inhaling of the odor must be more intens with Daliah's weight on it.
