Mistress Amelia knew that she had to dominate this guy and the best way to do it was to smother him. So she went out of her way to smother his face as well as trample and gag him a little. She did this with her boots but mostly with her nylon pantyhose. It was a great way for her to punish him and she loved every bit of it.
Mistress Angela loves to punish using pantyhose and when she had a new slave, she had to teach him to lick pantyhose because he would be doing a lot of that as time goes by. So she taught him so that he learned how to do it automatically whenever he would be called upon to do it and she told him to take it positively since it was in a positive environment.
