Little Alan and Sam were trick or treating, excited that despite being six years old their parents had finaly agreed to allow them to go round the houses on their own.
Alan a small skinney boy who was dressed as a ninja, with black skin-tight robes and a ninja mask hiding his face and his dirty blond hair. He carried a small plastic pumpkin in one hand full of the candy from other houses.
Sam was a little taller than Alan with frizzy red hair and a pale face covered in freackles. He was dressed as a superhero, a simple red bodysuit and a blue cape. His candies were in a gift bag.
The two boys were having a great time until they came to a house full of teenagers.
"Trick or treat!" They happily said. One of the teenagers, a tall muscular boy who looked drunk sneaked down at them and said.
"What are two babies doing alone?" He took some of their candies and gave it to his friends while they laughed.
"Hey!! Give it back!!" Alan yelled but he was pushed away by the older boys. Sam immediately ran to help him.
"Beat it kids! You don't have a chance!" The teenage boy flexed his small but at least noticeable muscles in his arms. "Come back when you get some hair in your balls!! Hahaha!! With that the other teens around him laughed as well. The two little boys ran off red in shame and sadness.
"Those jerks! We are old enough to ask for candies alone!" Sam angrily complained while he sobbed.
"If only we were a little older... we could fight them back!" Alan sighed looking over his shoulder at the teens still laughing at them. He wanted to give them a lesson.
"Well... we can't. They're bigger and stronger... and hairier. Let's get on to the next house" Sam pulled his best friend along hoping to distract him. They stood in front of an old house's door and almost immediately it creaked open. "Trick or treat!"
The old witch smiled down at them, "Oh! How lovely costumes you have!! You look adorable!!" She smiled as she gave them each a handful of her magic candy. "Have a nice night, dears!"
"Thank you!!" The two kids giggled before they ran off to inspect what they got.
"Oh wow!! I got gum!" Sam excitedly said.
"Really me too!" Alan replied and was going to put one in his mouth but his dad showed up and take the boys back home for their sleepover. Alan put the candy in his pocket and forgot about it for several hours until he made his way to the bathroom to pee before going to the bed. He found the gum in his pocket and popped it in his mouth before he unzipped his pants.
As he chewed it, Alan felt an odd warmth. It was a fairly cold night but a sudden heat filled his body. However, despite that, he became aware of a breeze on his ankles. He looked down and was shocked to see his pants were now covering only half of his calves! And that wasn't all. He noticed his shirt seemed tighter then before!
"I'm growing!" He gasped watching his sleeves go up his arms. He watched as his hands became bigger and muscles started to be visible on his arms and shoulders. Then when he put his hands on his chest he not just found out two growing pecs but several hair sprouting on them too!
"I'm not growing! I'm aging!!!" Alan gasped as he felt his chest hair thickening beneath his hands. Breathing became difficult as his torso kept swelling. He rushed over to look in the mirror, something which until recently he hadn't been able to do.
Instead of seeing a cute little kid, he saw a 18 year old man with a rough face and a lot of big muscles that finaly made his poor pajamas rip off and show off his impressive amount of body hair. He ripped the remains of his pajamas off and examined himself in the mirror. He was now 21 years old with a thick but trimmed beard, large hands and wide shoulders. His legs were thick like tree trunks and his feet looked three times bigger than before.
"What happened to me?!" He gasped in surprise by how deep he sounded now. He covered his mouth while he wondered what had caused it. Then, he remembered the gum and quickly spat it out. So, he stopped aging at 25. He kept looking at himself but he still can't believe it, his kiddish briefs barely held on round his large toned ass and his impressive and kinda obscene bulge. When he noticed the dense bush of pubes protruding from above the waistband he thought that his balls could be as hairy as well.
"I think I'm big enough to face those guys!" He smiled as he flexed for a while in front of the mirror but then he stopped when he remembered that he was naked. "I going to need some clothes. Maybe my dad's could fit me."
Fortunately for Alan, there was a drawer in the bathroom but it only has his father's bathrobe. He tried to put it on but it wasn't big enough for him. His shoulder and chest were so big that he didn't feel comfortable. But the worst was on his crotch, he desperately wanted to take his briefs off but he didn't want to be naked and particularly he didn't want to see his new hairy manhood. At least not yet.
Without anything else to do for the moment, he stared at himself in the mirror when he was distracted by a knock at the bathroom's door.
"Alan? Are you done? I need to pee too!"
