Oh, I know what you did. There's no way you can deny it. The only person who knows about my boyfriend sneaking into to fuck me at night would have to be you, you sneaky little ass. I thought we were like, on good terms as siblings! We're supposed to have each other's backs!

Whatever. Here's the way that I'm dealing with it... If you're going to stick your nose in my bedroom, I'm going to rub my cunt in yours. All over your pillow.
