Holy shit she's fucking retarded.....



And that friend of hers needs to seek psychological help, in no way shape or form is any of this normal for "siblings"

She doesn't bring spare undergarments? Not even panties? Did she even bother bringing extra pads or tampons? I wonder if the author has heard of this thing called "period" which can come very unexpected sometimes...?
