As much as you were angry with this little girl for what she was doing to you, you were curious and wanted to find a bigger mirror yourself. The two of you went to the bathroom where there was a large mirror on the wall.
“Oh Wow! Look at me! I’m getting huge!” said Allisa once she got a full look at her body.
You didn’t think she was getting huge. You were just getting smaller. She was actually taller than you now. Not by much, but you knew things were only going to get worse.
Trent looked at his own reflection. His hair was longer, his muscles had undeveloped, he was shorter and skinnier. Comparing the reflections he could see that whatever he was losing, Allisa was gaining. “Let it be stated for the record. I am very angry about what you are doing to me and I demand you reverse whatever you are doing and change me back. I do not want to become a little girl”
“Did I really sound like that? You sound like such a little girl” Allisa could barely stifle a giggle.
“Stop this now! I demand you change me back!”
“You sound so shrill!” she chortled “Look, I’m sorry the coins chose you. I was expecting to swap with my friend Trixie, not a boy”
“How do these coins work? There must be a way to change back?”
“After 6 weeks we just swap coins”
“Where are these coins? Show me”
“There is one in your pocket and I have mine here” Allisa showed you a small gold coin.
You felt in your pockets. Sure enough there was a similar gold coin in there. You examined it. It had a pentagram on one side and what looked like a maze on the other. “How did this get in there?” you asked “Did you reverse pick pocket me?”
“No. When you sat down beside me on the bus I was comparing the two coins wondering why I hadn’t swapped with Trixie. You bumped me and I dropped a coin. It must have decided you were my swap partner and found its way into your pocket”
“Well here take this” you held out your coin. “Give me yours so we can swap back”
“It wont work” Allisa said as she willingly gave you her coin and took the one you proffered. “I don’t know why but Mom says the duration of a swap is always 6 weeks”
You looked at Allisa’s coin. The pentagram side was identical to the other coin but on the reverse side was some sort of pattern of concentric circles. “It might just take a little while. The other change didn’t start immediately” you said wishfully
You looked at your reflection once more. Your hair colour was changing from your own brown to Allisa’s honey blonde. It was now shoulder length. Your face was changing as well. Your features were smaller. You looked at Allisa. She was an inch or two taller than you and her hair was turning brown. It was apparently retracting into her scalp. It was now shorter than your own. Her facial features were also changing, becoming more like your own. It was now unmistakeable that you were swapping bodies.
“Have another look at the coin I just gave you” Allisa suggested. Her voice was now deep. She had also removed her training bra. Her torso looked like a teenage boys. You glanced at her panties. There was still no bulge.
You looked at the coin in your hand. It had not left your hand, but somehow this coin in your possession had the maze pattern on one side.
“How?” you asked
“I don’t know how it works. Like I said, this is my first summer swap. When you get back to my house ask Mom to explain. She knows more about the coins than anyone. Just be prepared to be Allisa Ralphvernier for the next 6 weeks”
“Is this something your family does all the time?” you asked.
“Yes and No. Mom and Dad swap with each other a lot. We kids are only allowed to swap during the school holidays”
“How many of these coins do you have?”
“Two pairs. Natalie has the other pair. She will be swapping with someone today as well”
Natalie was Allisa’s older sister. She was in your year at school. She was very good looking but a strange girl. Trent had barely ever spoken to her. “Has Natalie swapped before?”
“Every summer vacation for the last three years”
“With someone from school?”
“Yes. It’s been Vicki Finch every year. She was hoping for someone else this year”
Vicki and Natalie were best friends. It sort of made sense. They were very much into mysticism. Vicki was a bit of a goth. “They are both so strange”
“Depends on what perspective you are looking at things. Talking of which, you should get out of your clothes. I think the interesting trade is about to start”
You looked back into the mirror. The changes had progressed. You were more Allisa than Trent. Your face was nearly Allisa’s and your honey blonde hair was down below your shoulders. Allisa’s hair now resembled the haircut you had possessed less than an hour ago.
Allisa was taking off her panties. You had a glimpse at her groin it was still flat. She caught you looking. You turned away embarrassed.
“I don’t mind you looking. It’s the first time I’ve had pubic hairs. Do you ever trim them?”
You looked again at her groin. It had a few pubic hairs. The hairs that you used to have. They were thick enough to hide her slit. There was no bulge though. "No. That's just how I am.... or was"
“Take yours off. I want to see what I’m getting. I’m going to see it soon enough”
You guessed you had nothing to lose. Your pants were falling down anyhow. You stepped out of them, then removed your school shirt. Lastly you dropped your undies to the floor, making yourself totally naked.
Your groin was now hairless. You still had a penis and balls although the balls seemed smaller. Embarrassingly you had a stiffy. Apparently changing sexes was a tun on.
“Oh! That looks nice!” Allisa “You’re a nice size!”
“You had better look after this!” you stated “I want it back”
“Don’t worry. I will look after it as if it was my own”
As you watched it seemed your balls were shrinking further. You clasped them with your smaller hands. “They’re shrinking”
Allisa caught your attention. “I can tell. I’m getting a lump”
You looked at Allisa’s groin. Sure enough she was developing a bulge below her vagina.
You glanced at the mirror again. You now had Allisa’s face. It seemed your whole head was now Allisa. You looked at your naked chest. You didn’t have boobs but perhaps you could say your chest was budding. Your nipples seemed enlarged.
“They are just starting to grow” Allisa had observed what you were examining
“Have you began having periods yet?” you asked.
“Not yet. But probably soon. Maybe you will experience a period before I do”
“That would be my luck!”
“Have you had intercourse with this dick yet?”
“No! And don’t you dare!”
That bought your attention back to your dick. Your balls were gone and your dick was shrinking. It was still stiff but now was only about 4 inches long.
“Oh wow!. My clit is turning into a dick!” Allisa's comment caught your attention. She had a growth coming through her pubic hairs. You also noticed her scrotum was now well developed.
You watched silently as your dick continued to shrink. Inside you felt like crying as it apparently pulled into your body. You were turning into a girl. A 12 year old girl, just starting with puberty. Turning into Allisa. You were going to be this way for 6 weeks. You tried to look at the bright side - at least the summer wasn’t going to be boring.
