When Jet challenges a new slave to a wrestling match, he thought he would be able to win. He didn't know that Jet planned on using a choke hold to put him to sleep. When she managed to get behind him, she immediately put him into a classic sleeper hold position. When she finally put him under, she laughed at him. This is how she lets him know who controls his very breath.
Mistress Katja doesn't like to punish her slave. She doesn't like to be disobeyed but when she has to punish, she loves to sit on him. She doesn't just sit, she sits so that she controls his breathing. She doesn't mind opening her legs and putting her ass on his throat, cutting his breath off. She strangles him with her hands. She enjoys sitting on his stomach and telling him how worthless he is when he is gasping for air.
