Busted! Part 2 (Patreon)

Looks like my  ̶l̶i̶t̶t̶l̶e̶ brother found his test subject-and it's ME!! 

I was just curious...read a some stories FA and thought I'd try some adult diapers out for myself. They weren't really my thing, but now I'm stuck with them for (at least) the next two years!! Big brother...I mean-litt....you know what I mean. Bro is saying that the machine only works on a person once, the change is permanent. That means I'll have to grow up all over agai-huh? WHAT DO YOU MEAN "Like...PERMANENT permanent"!??!?!??!
