Okay. We're getting into the daaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaark smut now. Go no further, ye who do not like that sort of thing. Read on, those that do. This is the last chapter of this story I'm posting here - the rest of it can stay on adultfanfiction.org and Hentai-Foundary.com. If you want to know how this ends / continues, go there. Or send me a note.
