You find an old pair of your son's best friend's sandals. You live by the beach, and he rides his bike over to your house with your son all the time. He usually has his backpack with a pair of sandals, and swimming trunks. He happened to leave them at your house last time he was here.
The boy had a...well...boyish face. His nose was a little long and angular. A strong chin, dark eyebrow that were always low with a look of concentration. Blue eyes, and dark hair. He had the top of his head died a dark reddish-blond color. He had a galaxy of small, reddish freckles that looked more like a light rash, than freckles. They covered his nose, and across his upper cheeks just below his eyes.
He spent a lot of time out in the sun, but was always careful to use a lot of sunscreen. He was also known to wear a body suit as well. So the kid had a farmer's tan. From his neck up, and along his forearms, was tan. His soft, not completely-fat upper arms and his torso were pale.
He had the beginnings of a light dusting of hair around his ankles, and beginning to spread up his legs. Again, his legs weren't skinny, but neither could you call them "fat." Both his feet and hands were also of medium build.
He was of medium build. Not fat by any means. But also not in the realm of "skinny" either. A-in-all, he was a really handsome young kid. His name was Max. Maximilian Brenner.

I got home from shoppings and threw my new clothes on my bed. I got changed into my workout gear. Getting ready for another grinding session of lifting. Always makes me feel great afterwards. My arms and torso looks like Vin Diesel. I'm very strong, able to bench 350 lbs. But I don't really bench press. Mostly do hammer curls, reverse curls, pushups, situps, dips, and pullups to look like this.
But I'm starting to get a bit old. I'm beginning to feel my age. At the age 37, I'm beginning to slow down ever so slightly.
In a few years, when my boy reaches about the age of 18 - 20, I'll begin to train him. I started at too young an age, and as a result, my back sometimes hurts. But Max definitely needs a little help, as he is quit soft.
An hour later, I cut my workout short and head to take a shower. I grabbed those new oair of socks, and without laying attention, Max's sandals. I then head to take a shower.
After cleaning myself off, I throw on a clean pair of shorts, those socks, and the sandals. They felt a bit tight, but then quickly loosened up. I then actually felt myself get shorter! My arms deflated, as did my chest as the air escaped my lungs. Then everything went dark for a minute or so, as I felt my face rearrange itself, and hair grew on my shaven scalp.
When it was all said and done, I looked down. My shorts fell off my smaller body, and my smaller paler penis hung there, hairless balls perkier and "tighter."
"What the fuck!?" I exclaimed in my now teenaged boy's voice nearing the end of puberty. I looked myself over. Everything was different! No body hair at all, save for a little dusting of brown down around my ankles, going up my legs, and fading into nothing.
My hands and fingers looked different. Much more youthful. Forearms hairless. I felt my now soft flesh around my chest and very slight love-handles.
My much paler chest and torso had more fat than I was used to, and I was able to grab a small bit all around my torse. And my arms! My now-soft arms!
I reached up to touch my face. My baby smooth face! No five o'clock shadow to be felt! The I felt my....HAIR!? on the top of my head.
I wandered over to the mirror, and there, looking back at me, was my 14 year son's friend, Max! I felt my face again, and the boy in the mirror did the same!
I looked closer at the face, feeling it with both hands. Max's face. Max's intense dark blue eyes with his low, long eyebrows that always made him look like he was ultra-focused. Max's red rashy dusting of freckles across his nose and upper cheeks. Max's nose and eyebrows. And Max's red-dyed / dark blond hair on top, surrounded by his dark ebony-colored hair on the sides, and showing through beneath the dye!
I couldn't believe it! I looked exactly like the 14 year old Maximilian Bennet! Exactly like him!
Also, my sore achy muscles were gone! No longer sore from post workout! Also gone, my big strong muscles I worked very hard for for the past 21 years!
My, or rather Max's penis, began to stir. I was horny! I'm in the body of a horny 14 year old boy!
