One of my favourite things about sizeofthatthing is the almost alchemical way the prompts can change from what they originally seem to suggest to something amazing. In which light, you should totally read this beautiful Nine/Jabe fic that anon wrote for my "gardening" prompt. (Kink-averse people: it's not even kinky, at least not any more than humanoid/tree would be anyway. And it's really very good.) ETA: It is of course adults-only and NSFW, yes. Should probably have mentioned that to start with.
