She tells you you're staying here for the night, wears panties like that, and then gets all hostile about the precise spot you're sleeping. Truly a great tease/tsundere.
I don't mean to be intentionally vulgar, but if I were in that situation and had the chance, I would destroy her pelvis.
How long has she been frustrated, waiting for the right man to come along?
She might destroy YOUR pelvis.
Not that you'd complain... ^_^
Don't you know that this isn't a place for humans to come?It's already quite late, so you're staying here tonight.You lost your way?You want somewhere to sleep? There's only one bed in the house, you know.
