you have an older brother who's 16 and is an adult baby one day your parents leave for a date leaving you two all alone while you're playing on pc you start hearing crying from downstairs so you decide to check it out

When you come downstairs you see your big brother crying on the sofa in pooped diaper

Oliver:"wahhh! Wahhh! Me messy! Big brother change mee!"

You:"shh shh don't worry we'll take care of it"

Your brother calms down and you go get the supplies you then return to him and start untaping his diaper

You:"who's my little stinker?"

You tease him while tickling his belly

Olvier:"hehe! Im! Im a little stinker!"

You then clean him and powder him then start putting a fresh diaper on him when you finish he crawls into his playpen and starts playing with his toys

Oliver:"hehe fun!"

You sit on the sofa and watch him play but when you turn around for a second you feel something soft hitting your head turns out your brother threw a diaper he had found in you

You:"ow! What why did you throw a diaper on me?"

You ask as you pick up a soft and cute teddy bear diaper from the ground and stare at it for a while
