Rick decided to make himself eight. It seemed like a good age, all things considered. Not too old as a kid, but not too young and helpless either. Yep, it seemed okay. So he pressed the button and waited, if a little apprehensively. So when the transformation swept over him, he was happily surprised that it was absolutely painless. He felt himself shrink and swimming in his old clothes. Of, course, they had become much too big. Rick could see the proportions of the machine and of the room being oddly off and his body was much slimmer and delicate. He undressed but stopped at his boxers, which he clutched with fright. He peeked an eye inside and saw that naturally his penis and scrotum had regressed as well. It was not unsurprising, merely... disconcerting. Rick would have to come to terms with the fact the was much smaller and weaker than before. Ands once he gathered new more appropriate garments, he could do fun things as a kid, like eating as much junk food as he wanted, have fun on kiddie rides and do all manner of mischief that only kids are tolerated to enjoy. Yes, that sounded like a right time to have!
While he was pondering on all the fun he'd let himself enjoy, a nurse entered the room, holding folded garments. She was tall for Rick but seemed nice enough.
"Ah, here you are! Put these on and then you can enjoy your new age outside through this door. No worries, you can come back and change your age back into this building as soon as you want."
Rick thanked her slipped on his new clothes once she went away. He had to admit they were strange,. Little shorts, a simple loose long-sleeved shirt and a pair of sandals. Well, they might be short on decent clothes. He then went through the door indicated by the nurse and stepped into the forest beyond, impatient to try rides. Little did he know (yet) that he had already stepped into a trap. Indeed, the building behind him vanished, stranding him in this realm. It was the fay realm, and the nurse he'd met wasn't one at all. The resort had a deal with the fay realm. In exchange for magic, they'd send regressed adults into the fay world. Fay creatures reproduce with great difficulty and they think young humans make the best pets and children. Transforming them further is easy for them And Rick, dressed like a cute little boy, was sure to attract them soon, and in droves. Rick's transformation might be the only beginning and he might find himself with a new family very, very soon...
