Lady Sarah could not believe the audacity her husband had for hitting on her friend. She thought it was a fabricated story until she got the evidence. She confronted him but he tried to lie to her and brush off the story. But she knew what had happened and she did not buy his excuses. So she ballbusted him in the woods after stripping him naked. He never did it again
Lady Sarah does not like anyone messing with her money. You can do anything to her in the world, but do not mess with her money. She goes above and beyond to make the money and she will never sit back and watch someone else mess with her money. That is why she chose to dominate and humiliate this guy by ballbusting him. He had to feel the ultimate pain.
