"T-thiS, isn't whAt I pAid for!" screeched your new dad turned more older brother, who despite the altering reality, was continuing to shrink in his adolescent attire.
"You're looking rather cute, honey," said your new mother, as she squeezed his now beardless cheeks as her husband shrunk to be shorter than her as the last bits of puberty left him as he shrunk to more of a boy's height and frame, and his hands and feet--once large, shrunk to more proportional sizes. The American Fighter tee shifted once again, this time to a Pokemon tee, and his Wranglers shrink to match the candlestick thin legs that his boyish body now stands upon. His dark brown hair is slightly fairer, almost dirty blond and a little long, but neatly kept, giving his rounded face an almost cherubic like appearance.
"Why did I get so young?" asked your older brother as he looked at how his rough paw-like hands had now shrunk to uncalloused soft hands.
"Isn't he perhaps a little too old to be my son? I'd have been barely older than him to have him if he stays this old," said Mom to Lao Yi.
Lao Yi, who until this moment had been seemingly panicking, suddenly took control of himself, simply sighed and said, "I might have gotten the dosage off a bit, madam."
"Honey, did you want me this young?" asked your brother.
"You think I liked being a rancher's wife, honey? Don't get me wrong, I loved your body from all of that labor, but the rest of the life as a rancher's wife? It wasn't for me... so this time, honey bun, we're gonna live like I want, in the big city."
"No!" whined your older brother before he burped and started to shrink again, baby fat slowly being reacquired on his face and tummy as he left the double digits of his life, and his clothes shrunk with him, shifting into ever more childish looking attire.
"Don't worry honey, you'll still get the experience you wanted of having a little boy looking up to you, it's just he's gonna be your little brother instead of a son," said Mom.
And with that your older brother stopped growing younger as he looked only two years and a few inches older and bigger than you did. The six year old who a minute ago had been a big burly rancher now a sobbing little city boy.
"Here's the deed to the ranch, as per our agreement," said Mom as she pulled out of her purse an envelope in which said deed was contained.
Lao Yi took it from her, and said, "Pleasure doing business with you, Madam, and don't worry, after tonight, your sons won't remember their previous lives all that well, they'll slowly start to feel more and more like a dream to them."
"Something you put into the tea?" asked Mom.
"No, it's just the nature of getting that young... the mind can't hold onto all those adult memories for too long, it's not developed enough. You just barely escaped such a fate yourself by asking to be about 25 years old. Much younger and your memories would also be in danger of being lost."
"Turn me back!" pouted your brother.
"Not going to happen, and if you keep pestering me, I'll give you a good smack on your bottom--and don't believe I won't right here in the mall, because I most certainly will."
Your brother blushes and remains silent and sniffling for the remainder of the visit to Lao Yi's shop. Soon though, they are stepping out of the shop and walking to a new apartment home that Mom had gotten the keys to in exchange for the ranch. It would be there where their new lives awaited them.
