Soooo yeah. I put up one decent, if short, entry to a series, then vanished for 6 months. I'll try not to do that again. Anyways, this is a new little series, once again, inspired by a roleplay with a lovely lady. If you liked the first entry of Spellbook, you'll probably like this too. Let me lead off: this story contains graphic and explicit content, don...
