The slave is trapped in a box with ahole for his head, he cannot turn away, he has to take with the upturned face, what Daliah will dishe out.
Lesson 1: sock-smell, completly helpless he muts inhale the fine aroma, or may be the stnky smell from the socks, fresh out from the boots.
Then he has to remove the socks with his mouth and she shoves them in his mouth... if he don't corporate she can simply use the pressure of her body weight... face trampling is so easy for her.
In the second half, she walks barefoot over the face, standing on time with one foot right in the middle of the face or another time she stands with both feet, facesqueezing again.
Some little breaks, he must now lick the toes... or What?... hehe more pressure, fullweight on your face until it's smashed.
The slave is ready on the floor, Isabella steps on him, but she decides to make a more comfortable game... for her, not for him.
She let take a first smell of her sock, sits down on his belly and places the feet on his face.
Now, with both socks on his nose, the odor is intensive, because Isabella don't wear fresh socks for a footfetish session ;-)
She let him remove one sock with his mouth, then she places her bare foot on the sock on his mouth and nose, sock eating and smelling miam miam... fine!
After removing the other sock in the same way, she begins to play and squeeze his face with her bare feet....
