This neighbor was not well behaved and he ended up pissing off lady Fenja. She had to show him what she does to people who act the way she did. That is why she used her whipping fetish to dominate him and to teach him a lesson he had never been shown before. The poor guy realized he needed to change and he made the changes immediately to avoid further humiliation and punishment.
Lady Fenja had never whipped anyone before and she was dying to. She had to try it as she had thought about it for a long time. She however had to wait until an opportunity presented itself. And it did when this guy defamed her. She did not sue but rather she went ahead and she crushed his nuts and whipped him while he was naked. She had fun doing it and even forgot why she was doing it.
Lady Fenja wanted this guy but she wanted him to change. He was out of shape and it was not good for their sex life and it was not good for his own health. She had tried to talk to him but when he did not change and he suffered a scare and was advised by doctors to maintain a healthy lifestyle, she had to step in and make him workout. And she did this by whipping him painfully while naked so that working out seemed like the easier option.
