Babysitter to Babysat

Alex checked himself from the mirror before entering the house. He was a short but well-built ginger guy. He was nervous when he entered Mrs. Johnson's house. It was his first time babysitting because he needed some money for his date.

"Welcome, Alex!", said Mrs. Johnson, "Phil and I were waiting for you. I am sure you two will get along!". Then a 8-9 years old kid came from upstairs "No we won't! I don't need a babysitter.".

"You must be Phil then. Hi champ!" said Alex. Phil was still frowning. Mrs. Johnson then said goodbye and then left the boys. They went to living room together. Phil was still angry.

"Hey, stop with the face. I am only here for till night. Plus I am not a strict babysitter or something." said Alex. Phil immediately answered, "Well, it's not like I need you.". Alex couldn't stand him anymore "Oh you definietly do! Now go to your room while I make food for you."

Phil thought "Oh we will see who is needing who." and secretly took a photo of Alex before going to his room. He opened his computer with a grin. He heard about a website that can transform ages between people. All you had to was to upload their picture. One of his friends from school used it to punish his former old, now younger brother.

He uploaded both his and Alex's pictures and entered 20 and 8. "If I switch our ages, he would still be 8 and maybe somehow resist to take his power back. So I must make him younger", he thought and entered 1 and 27 and clicked change. 

He immediately went downstairs to see the changes. But he already felt he was getting taller already.

Alex realised something was wrong when his t-shirt and shorts started to feel lose. The shorts got so loose, they fell on the ground. He then saw his manhood which was slowly going back up toward his body. That's when Phil who was getting bigger came from upstairs. "What is happening to me?" said Alex with a cracking voice. His hard earned muscles were fading, leaving him skinny.

"I said I didn't need a babysitter" said with a deep voice. His clothes got so tight he had to take his t-shirt. His skinny body gained muscles and some black hair appeared in his chest. "Stop this" said Alex, almost 5-6 years old. Phil said "Oh don't worry, it will stop when you will land on your all fours.". 

Alex then started crying, which was the only thing he could do. "Me no baby! Cwange bawck!", he said. All Phil did was to laugh. The changes stop when he was towering over Alex. He picked the little baby from the pile of clothes and tried to shoosh him. It was gonna be a fun and vengeful day for Phil.
