Title: The Bet
Prompt: Writing Prompt #58 - "Do you like girls or boys? It's so confusing these days"
Word Count: 3000
Warnings: Threesome, a touch of incest, rampant bisexuality
Author notes: VERY AU. Has little resemblance to canon post-OotP, but set after Voldemort's defeat (Ginny is 18). Big thanks to misfit_ragdoll for lots of love and beta work.
Disclaimer: Harry Potter belongs to JK Rowling. Just borrowing the characters. (But considering what she did to poor Tonks, I kind of don't want to give her back)
