I've sent a pm to you both, so you already know how I feel about the story, but I'll comment here for those debating whether to take the time to read the whole thing. If you haven't read it, do so. Don't skim through it because it's long. Wait until you have time to read it all slowly.
I've read thousands of stories over the years and this is the single best piece of erotic fiction ever penned. It was simply the story every other story here will be judged against from now on. Period. Congrats to you both.
