I can feel my feet inside his throat

It's been a long time since I haven't challenge my slave mouth with "foot gagging". So I'm starting the rehabilitation of deep feet program! This time I will be very severe, since I have not destroyed his throat with my feet in a long time. There are no marks all over my foot, just one mark that he has to reach. I will encourage my slave's mouth until it goes so deep that it can pass the mark. It was very hard... At the beginning he couldn't even put my foot halfway into his mouth, he lacks a lot of practice. I can feel My feet inside his throat as I move toes to make him GAG, I do with my both foot! Backwards first and forwards foot gagging... he choks and can't take it anymore, but I keep pushing hard until I reach the limit. He can't handle anymore, he needs a little help, so I use my fingers to open his lips and make him stick his tongue out! At the end I ordered him to lay at the sofa face forward... that position makes is better for deep throat! Let's see if it succeeds!
