This lil one it's my main fursona.His name is Gus. This is his ref sheet,made by NIEVE,an awesome artist in FA.(don't know if she's around here yet)

He don't has a certain age.He can be from 3yo,till 12yo,but in all those ages,he still is in diapers.

he's a boy,but the more he is younger, he is more sissy.This don't means he'll be a full sissy when 3yo,but he don't mind trying some girlish diapers or dresses at that age.
