Lady Scarlet had beef with her husband and she wanted to humiliate him. So she chose to cuckold him. But he was lucky as she was not mad enough to go all the way. All she wanted to do was to do just enough to send a statement. That is why instead of fucking the guy she was with as her husband watched, she just jerked him off. She then told him that next time she would fuck him if he did not change. He changed.
