Becoming the schoolgirl

Part 1:

Paul was failing his math class. He wasn’t stupid, he was just lazy and didn’t study at all. By the time he wanted to do something about it, it was too late. Failing in his school would have meant that his graduation is being delayed. So, he tried to find another way around. There was a rumor about someone in the woods selling a drug that can change others' opinion. It sounded fake but Paul didn’t have any other option so he gave it a shot. He ventured into the woods and soon, he found a cabin. He was scared but he knocked on the door. A mysterious woman opened it who somehow knew his name.
‘I know why you are here.’ –said the woman. Paul was shocked but also curious. ‘Are you a witch?’ –he asked. ‘Let’s not talk about me now. You are an honest boy so I’m going to help you. Here is a potion. Drinking it will change you into a girl whose name is Samantha. No one will notice that you became a girl, your old self never existed. In this way, your teacher is not going to fail you because you are beautiful. However, be aware that you need to get back here before tomorrow midnight to drink an antidote, otherwise, the changes will be permanent.’ –said the woman. Paul was still stunned, but he needed to do this to fix his mistakes. He drank it, hoping that it wasn’t a potion, and he went home to sleep, as the woman ordered.

Part 2:

The next day something unbelievable happened. He woke up as a girl but strangely, his parents didn’t notice anything. However, there was no time to waste, she just wanted to return to her former self. She didn’t find any of her old clothes, just skirts and heels. It was embarrassing and difficult to walk in them. She went straight to his math class, hoping that soon this would be over. But then, she noticed something strange. She seemed to have fallen in love with her teacher and vice versa. That witch must have put something into that drink, but she didn’t care about it.

As the class ended and everyone left the classroom, Samantha and his teacher started making out. They could barely stop and the teacher invited her to his place after school. She had never been this excited. The afternoon quickly passed, as they had sex over and over. This was Samantha’s first time, as Paul was still a virgin, but she just kept cumming. However, at the last moment, she remembered that she had to return to the witch. She left everything behind and she started running as fast as she could. But she couldn’t find the cabin anywhere, it just disappeared without a trace. Samantha looked at her phone and noticed that it was just over midnight. She started crying, knowing that she will never be Paul again.
As the time went on, Samantha got used to her new life. She is still having a relationship with her teacher. They are having sex every day, either secretly at school or home. After all, she got the best mark in class, however it has come at a great cost.
