This is very good stuff, and I do want to see it continued. Personally, I would classify it as Supernatural, but those posting categories are for convenience and you'll labeled your work sufficiently. I like that it's supernatural, kind of like a tossback to Twain's Mysterious Stranger, or Steven King's preeminent Randall Flagg, were either of these characters more explicitly pornographic in their sexual lusts. It gives him opportunities that the rest of us lack, but would surely like. Anyway, that's your call on posting. You'll get more readers in one-on-one.
So, super debut post on RU! Keep them coming.
