Prompt 1 - Fic: Severus is the newest Bachelor, and is beyond surprised that Harry Potter is one of his suitors...does he give him a rose? The crackier the better, and if you poke fun at the idea of finding love on a reality show, that'd just be icing on the cake. It can be sweet too, but I'd love to see more of a humorous piece for this one.
Prompt 2 - Art: Any kink that doesn't get a lot of love in art or fic (this would probably be the more extreme ones like pet play, watersports, blood play, etc.) So, bondage, D/s, spanking and things like that are out. R and NC-17 only, please. ;)
Prompt 3 - Fic: Snape takes Harry to raise after Lily and James are killed (maybe on Dumbledore's orders, or against them, however you wanna work it). Snape is the only father Harry's ever known but as he gets older his feelings start to change to something not even remotely resembling familial love. Angst, incestuous overtones, reluctant or even outright horrified Snape, would be excellent bonuses. Actual sex is up to you, but I'd prefer Harry to be at least 16. Anything before that should stay in his sweaty teenage wanking dreams. :)
I'm also good with the author/artist being inspired by one particular aspect and just going off on their own tangent, so don't view these as restrictive; they're not meant to be. :)
