Arrived one month after the kidnapping by dragon fire, with Twilight Sparkle's Royal seal:

Dear Princess Celestia,

In the time that I've been gone, I have been raped and tortured extensively. Master has hurt me, broken me, and built me back up so many times that I'm not sure what I am anymore. Love and hate seem hand in hand, Master is my entire world and everything I despise as well. Other ponies are beginning to mean nothing, and it scares me. Sex is nothing anymore, it's as breathing or walking. I do it for master in every way he asks, in any way he wants.

Nothing has changed physically, I'm still me, but mentally I'm different and broken. Gone are my easygoing gentle attitudes. Sanity and serenity have left me, and every day I wonder if I'd be better dead. As sick a joke, I can't even die at his hooves. Victory seems assured for him and in a strange way myself as well. Every day I am more what he wants of me and less what I was. Maybe you should just forget me, leave me here to suffer forever. Eventually, maybe even soon, I won't be suffering.

Twilight Sparkle

P.S. Master told me what the tally was. I screamed your name in pain and fear one hundred and twenty five times. I called out to you when I came three hundred four times. Masters name graced my lips during five hundred and ninety four mind blowing orgasms. That third category is the only one that will change now, even as I write this letter his tongue is caressing my folds and his hooves are on my flanks. May tail is raised for him in reverent deba~uc~he~r~~~~~~~y.~~'~~

It's five hundred ninety five now, Princess. His tongue is licking me deep.

I'm ready, Master.

The bottom of the paper is stained in a clear fluid.

Author's Note

Well, it looks like I had more time and more letters to write. Poor Twilight, at least she's trying to communicate her feelings!
What do you guys think? It's never what you asked for, but is it at least something you can read this time?
