Bound helplessly and smothered

Description: How do you feel down there? bound and completely helpless at my feet? you've to understand, someone like you, isn't even allowed to breathe the same air as your mistress. and for this reason, i'll first tape your mouth, so you can only breathe through your nose - and then start to smother you. and when i allow you to breathe, you'll only breathe through my sweaty nylons - inhale the stinky foot smell instead of clean air! i'll smother you with my feet and my hands - but either way, if i let you breathe, you'll only breathe through my nylon feet. how long can you endure this mix of oxygen deprivation and humiliation?!
