Can't Everyone Talk to Snakes?
Well this is more a Draco fic than an Astoria fic but both characters are very well-developed. It is however a very good black comedy, so if you want them to be happy/ don't like black humour than you won't like this. If you do however it will be the funniest thing you have ever read. Also it is a professor rating just to warn you.
