The mistress was an athlete instructor a while back, and she decided to chip in this time round and help out her sister who was competing this year. She trains her on everything that she needs to know and she is making her proud. A day before the Olympics, she takes her sister, and they go asses the grounds and when they were getting out of there, she saw a man stroking his dick while looking at them, and she felt disgusted. She tells her sister to go ahead, and she approached him, and she decided to give him a lesson on how to do it because he was doing the wrong thing.
