Tom was a quiet, introverted 12-year-old boy who loved reading and learning new things. His older sister, Sarah, was the complete opposite. She was boisterous, outgoing and loved to torment him.

Tom was fascinated by hypnosis and had read several books on the subject. He decided to use his knowledge to teach Sarah a lesson.

One day, when their parents were away, Tom seized the opportunity. He told Sarah he had learned a cool magic trick and asked her to participate.

Sarah, curious and unsuspecting, agreed. Tom then proceeded to hypnotize her, and to his surprise, it worked. Sarah was under his control.

Tom gave Sarah the first command. He made her clean his room, a chore she always avoided. Sarah, obediently started cleaning, unaware of her actions.

The second command was to apologize to him for all the bullying. Sarah, still under the hypnotic spell, expressed sincere apologies, much to Tom's satisfaction.

Next, Tom made Sarah cook dinner, a task she had never attempted before. Sarah followed the instructions flawlessly, preparing a meal that surprised even Tom.

For the fourth command, Tom made Sarah do his homework. Sarah, who usually scoffed at academics, dutifully completed Tom's assignments.

Finally, Tom made Sarah promise to treat him with respect and never bully him again. Sarah agreed, promising to change her behaviour.

After completing the commands, Tom left Sarah in a hypnotic sleep. When she woke up, she remembered nothing of what had transpired.

The days that followed were peaceful for Tom. Sarah was more respectful, helpful, and stopped her bullying ways. Tom felt a sense of victory.

Things were going well until one day, Tom found Sarah reading one of his hypnosis books. She was particularly interested in the section about post-hypnotic amnesia.

Tom panicked, but then he remembered the promise he had made Sarah give under hypnosis. He hoped it would hold, even if she discovered his trick.

Days passed, and Sarah continued to be the model sister. She kept her promise, treating Tom with respect and taking on her share of the chores.

Tom, however, couldn't shake off the guilt. He wondered if he should tell Sarah the truth, but the fear of her reaction kept him silent.

Sarah, on the other hand, seemed oblivious to Tom's inner turmoil. She continued to be the perfect sister, much to Tom's relief.

As time passed, Tom's guilt started to fade. He began to believe that Sarah might never discover his secret, and he could continue living in peace.

Tom graduated from high school with top grades, a feat he attributed to the peaceful atmosphere at home. Sarah, too, was doing well in her life.

They both went off to college, and even though they were far apart, Sarah continued to be kind to Tom. She even sent him care packages from time to time.

Despite the distance, Tom could see that Sarah had truly changed. She was no longer the bully she used to be, but a caring and supportive sister.

On one of his visits home, Tom found the hypnosis book again. He looked at it and remembered the events of the past. He felt a pang of guilt, but it was overshadowed by relief.

Sarah's transformation had been a blessing for Tom. He had peace, freedom, and a sister who cared for him. He decided to keep his secret locked away forever.

The siblings maintained their bond over the years. Sarah remained kind and respectful, while Tom became more confident and outgoing. They both thrived in their respective lives.

Tom eventually put the hypnosis books away. He focused on his studies and his future, leaving his past behind. He was grateful for the change in his life, even if it had come about in an unconventional way.

Sarah, too, seemed content. She continued to be kind and respectful, not only to Tom but to everyone around her. Her change in behaviour was noticed and appreciated by everyone.

As they grew older, Tom and Sarah remained close. They shared their triumphs and failures, their joys and sorrows. The bond between them was strong and unbreakable.

Tom's secret remained hidden, and the hypnotic spell was never reversed. The siblings lived their lives in harmony, their past differences forgotten.

The hypnotic spell had changed their lives in ways they could never have imagined. It had turned a bully into a caring sister and given a tormented brother the peace he craved.

In the end, Tom's revenge had not just taught Sarah a lesson, but it had also transformed their lives. It was a twist of fate that had brought them closer than ever.

Tom and Sarah's story serves as a reminder that change can come from the most unexpected places. And sometimes, it is the most unconventional methods that yield the most surprising results.
