The slave is trapped in the floor with a hole for his face, he cannot turn away, he must take all what Lady Amy dishes out... and this is f***ing alot!
First with the boots, after teasing with on foot, she steps fullweight, crushing the face seriously under the hards sole, on the poor face.
Applieing the most pressure, she gives the face a new shape ;-)
The she removes the boots, let him inhale the divine odor of her socks, and more odor under pressure.
After some stinkysock face pounding, she does it with her bare feet... between her toes is the most smell.. mjammjam.
Inside the boots is also a lot of gas, what he must inhale... he cannot move away from this chemical attack.
