Ok so

Im fr this time

I will do Uranatune if it's in a AU where they aren't siblings or cousins
also you can suggest kinks for the chaps
I will not do

Earth x Europa
Moon x Sun
Mercury x any of the gas giants or venus(last one can be broke a lil)

I think that's about all

If you don't like Uranatune you xan choose to ignore this book,Although it's very little.
