Skirt and fishnet stockings foot gag long session (slave tried to give up)

Today when i came back home, i had to check my reddit on pc and while doing that i decided that my slave could be a good footrest. after some minutes of worship and foot gagging warm-up under the desk, i was inspired and i decided to move him on the bed to keep the foot gagging. this was a long session and after a while my slave was exhausted and he was not opening his mouth properly. i had to remind him who is in charge by kicking him till he opened his mouth again. in the end i decided to trample him and to make him kiss my feet even if he was exhausted. eventually he had his reward and he could enjoy a footjob with my dirty socks.
