When she works out, it's only to get stronger so she can start to choke her slave and put him to sleep. After a session at the gym, she calls her slave to her. She puts him in different choke holds, allowing him to catch his breath between poses. She knows that he is struggling to stay awake but she is stronger. She chokes him until he starts to pass out.
When she gets her slave, she knows that she has to train him. She is happy to pull him over to her mat. As she wraps her legs around him and starts to put him into different choke holds, she gives him her rules. When he is ready to move on from that hold, he has to agree. When she is finished with her rules, she is happy to put him into the ultimate choke hold and put him to sleep.
