On one side Ty thought Dustin had earned his changes and would even need more. The other side were memories of the more loving foster brother Dustin had been years ago. Ty wanted to hug his brother without fearing that Dustin would beat him up for it. Soon he got an idea how he got that while also punishing Dustin even more. As Dustin had now a character and the manners of a bully, Ty didn´t need Dustin as a person capable of anything. And maybe his foster parents would be nicer to him if Dustin wasnt bossing him around and bullying him. So he quickly planned what he would do. When he was finished he summoned Dustin to his room with his powers.
To Dustin the whole evening was catastrophic. Somehow Ty had made him look younger and less developed, and his parents thought it normal. How could he turn back? Maybe he would do so over the night, or he would need to beg Ty to change him back. He hoped for the former.
While he was thinking he felt the same sensation he did not long before but somehow felt even worst. “What …?” as he felt his underwear thicken into a diaper. Ty had come to him and smirked.
When Dustin appeared in his room, Ty quickly stood up to smirk. To enjoy the situation more he made a silent wish for Dustin to lose his ability to use the potty. He wouldn´t need it anymore anyway. Ty thought it was super funny to see Dustin with a clear diaper bulge.
"Mom Ty somehow got me in a diaper!" yelled Dustin
"Dustin again stop blaming your foster brother for you under development. Yes you are as developed as a 13 year and not potty trained. But that isnt Ty's fault" yelled his mom back
Ty then grinned at Dustin, making another silent wish for Dustin to forget everything he learned in school. Ty enjoyed looking at Dustin start to panic as he realized he couldnt read or even do simple math. Dustin wouldn´t need to know, so Ty would simply make the changing wishes silent as well. As he already thought about Dustin as his, the first thing he wished for was that Dustin's clothes vanished and be replaced with baby like clothes. So soon he was wearing a big onsie.
Dustin suddenly felt embarassed as he now wore baby like clothes.
Meanwhile Ty couldnt help but laugh at Dustin. He was practically a baby.
"Ty stop laughing at Dustin. He might be almost the same as a baby but he is still older then you" Ty heard his foster mom yell clearly hearing the laugh.
Ty wasnt done. Next he quietly wished Dustin only had baby teeth and only a handful at best.
Dustin is horror felt his teeth either disapear completely or turn into baby teeth. Clearly not enough to chew most solid foods.
Ty saw Dustin was almost in tears at this point.
“What´s the matter, Dustin? Baby not like being pretty much a baby!.”
"No!" yelled Dustin
Next Ty made Dustin's bedroom furniture giant sized version of baby ones. Like a crib, changing table, etc that could hold a 13 year old. Dustin looked around growing more fearful of what would be next. Next would be his ability to speak. Soon Dustin couldnt say full words and sentences. Except maybe small words but mostly babbles. He was practically a baby now.
Ty then...
