Well, first things first - serpents. Lately, I've been getting the urge to play, or play with, a lamia. A woman with a lower body resembling a snake's tail, that is. I have no specific ideas - it could be a one shot, but that can be figured out later. If needed, I can provide some pictures of what I had in mind. Some drawings by a friend of mine are what got me into it in the first place, so it won't be that hard.
As for these other wholesome tales, I could go for a simple incest game. Siblings, preferably, or mother/child - though I lean toward the former. Most likely a one-shot, but that's not to say I won't consider making it longer, if that's more interesting.
Feel free to browse my ons and offs for inspiration, ideas, and fetishes of doom.
