After a boot-trample session, Daliah orders her slave for a barefoot smelling session.
In the beginning, she taakes off her boots and let him inhale the strong odor from inside the boots.
Then it's time to smelll her bare feet.... and this works best under pressure, means she stands on him, while he has the foot on his face.
Shee steps aso fullweight with both feet on his face, more pressure > more intensive smell ;-)
