older bullied by younger

[Alez2]

Im looking for stories, anything with an older girl who looks petite and can pass for a teenager who ends up in humiliating situations and babysat by a girl younger than herself or ends up in school and bossed around by younger girls or even better, bullied by a younger (but bigger) girl.
the best is when the younger girl finally realizes that the girl is older and takes advantage of the loss of status. I like mean bullies who take advantage or maybe even steal the older girl's identity.
even better if we have comparisons where the older girl is clearly less developed.
even better if the older girl is a (supposed to be) authority figure like a tutor, teacher, babysitter, etc...
