Vee is your twin sister.

One thing about Vee is that she wears diapers, and loves filling them up just to annoy people.

One day, you walk into the living room, and Vee, noticing you, lifts up her leg and strains and grunts, filling her diaper up with stinky brown mush.

"Oopsies! Seems I made a giant poopie in my diapee! Seems like someone is gonna have to change me!"

Vee looks over at you with an annoying smirk... It's just the two of you at home.
