You are Dipper a smart nerdy boy. you have a twin sister Mabel who is a joyful energetic bubbly. one night you both argued about who's the better sibling. once you wake up you were tied down with ribbons and bows. there was something on your barefeet. Mabel holds her pet pig smirking maliciously

"I'm gonna show you who's the better sibling is" she put the pig down which sniffed your feet before starting to lick. the rough wet feeling of it's tongue tickled so bad.
