Foot gagging saliva with belt to keep my feet inside slave's throat

Description: I created a new device to make my slave suffer on my feet. i used a head rest together with a belt so that when used around my foot and slave head, he cannot escape and can only gag, choke and vomit, till i take the belt off. i started stuffing my socks in my slave mouth so that he was prepared to take my big feet.then i pushed my feet in my slave's mouth and i tied his head to my ankle. he started to struggle a lot, his head was going up and down, trying to take off the foot from his throat but it was all useless, cause the belt prevented him from escape. while he suffered like that i just ignored him, watching my phone and only i could decide when the belt could go away and he could stop choking and gagging.i tried a couple of different positions and i enjoyed this session a lot. of course in the end the slave was destroyed.
