Absolutely careless face and throat trample in dirty sweaty socks

Description: Here is some dirty blue socks: i was wearing them for few days in a row (to the gym too, by the way), so my slave's really lucky to have an opportunity to sniff them. i'm trampling his ugly face and throat in these smelly socks hard and mercilessly: standing for a long time, stomping and kicking, marching on the face and throat. i make him sniff them while i'm standing full weight on his face. actually, i've decided not wash these socks, but leave them dirty for a good occasion later..
