You are searching for shoes to try these socks and find your neighbour Mark's shoes.
Mark is 18 and a basketball player, but these shoes are for a 11-year-old. You remember Mark's mother gave it to you when you were 9 and Mark was 11, Mark wanted these shoes so his mom bought them, but he wore once and hated them, so his mother gave it to you so you could wear it later. But then you and your parents forgot them and they were here since then.
You put on the socks and shoes. Shoes are at least 2 sizes too small for you, so your heels are sticking out. Seconds after putting them on, you feel like an idiot because you're even trying.
But then, you feel a slight wave going through your whole body, and you notice that your clothes are loosening, and the shoes are becoming more comfortable. Then you notice that you're the one who is shrinking!
No, you're not just shrinking, you're getting younger! Your body hair receeds, and your hair gets longer, your not-even-slightly-built body starts gaining muscles, not too much but better then they used to be.
You run to a mirror and see that this is not your body, it has never been! It is an 11-year-old Mark, looking back at you with worry in his blue eyes.
You start checking this body out, you were never close with Mark, though you keep seeing him in the neighbourhood, so the face is not that unfamiliar.
But you've never seen his body this close.
You still have black hair, but your eyes are now blue. You are no longer 5'11" (180 cm), you're 4'7" (140 cm) at most.
You pull your too large t-shirt up and see 4-pack abs looking back at you. Also you can see that your arms and legs are much more defined.
"Wow thIS is niCE" you say and right after that, you close your mouth in disbelief, your voice was much higher, and it was cracking a little bit, and you can't see any sign of an adam's apple.
Then your boxer fall down because you closed your mouth with your hand which were holding your boxer. You see that there are no pubes around your now "boyhood". Your balls are much smaller and your penis is 3 inches (7,5 cm) at most. You try to touch it to see if you'd feel anything, and you see that it is much more sensitive!
You began stroking it, but you feel guilty like you're doing something wrong. But you keep doing it while you're thinking about naked girls.
Suddenly your thoughts change and you began thinking about boys. Wait Mark is gay?!
Anyway, you keep stroking, it gives you some pleasure but you're not yet able to cum.
You go back to your room to see if the reality is altered, and you see that...
