Twilight/harry potter crossover

HI! I'm looking for a story were harry is a newly changing submissive creature a half demon half angel I think and his mates, Draco a dark elf or vela, Edward and Jacob from twilight and later on (demon) bill or Charlie weasley this happens when Draco breaks there mate bond over his darker more sadistic side.

Draco later takes and tortures a young submissive in a sick S&M play, when Harry's grandfather warns him he has gone to far and will permanently damage or sever his and Harry's mate bond he does not care and goes back to his torture.

In this story dumbeldore is a sick twisted pervert that desires harry for his rare creature inheritance, he also kept James potter, Alice and frank longbottom and the prewett twin brothers in there animal forms for over 10 years and later on Sirius.

I remember a scene were dumbeldore kidnaps harry and nearly rapes him in front of James and the others when his very sensitive wings grow in and dumbels damages them, this is also the time his grandfather comes in (I think he is the demon king or very high up in the under world, bill or Charlie works for him as well).

Harry has a demon grandfather an angel grandmother and has three or more children with his mates, one set of twins he had to deliver him self as everyone was away, I might be wrong or thinking of another fic but seth might have imprinted on one of the kids.

Well that's it on my memory hope its enough for you, its a great story I would love to read again with your help of course.
