Head locked deep feet challenge

I finally got a device to keep my slave head still, so he can't take my foot away from his mouth by rotating his head left or right!i immediately wanted to try it doing a deep feet challenge. the device was perfect, my slave couldn't absolutely remove my foot on his own and had to wait and suffer till i decided to take it out. after a warming up of his mouth and troath, i started to go deep and he started to vomit a lot.this is a pretty straightforward and simple video where i tried to go as deep as his mouth and throat allowed me to go with my big feet.
