My Twin is a Bully

Description: My twin stepsister is the worst! she's always bossing me around and teasing me about being a nerd. she walks in on me bent over with my panties sticking out of my pants and laughs at me and makes me give myself wedgies. she sneaks a few embarrassing photos of my ass in an atomic wedgie and threatens to show everyone at school what a loser i am unless i agree to do her homework. she's such a bully!
