Can you please help me find a book?

Bella is changed into a vampire and she has a potent aroma that attracts male vampires from all over the world. The Cullen's bring her to Isle Esme to seclude her, but a vampire arrived and Bella ripped his penis off and used it as a dildo. In this story, it seems like she is addicted to sex. If I am not mistaken Jasper is a part of the Volturi and he is coming to see Bella.

Sorry about the vague summary, but I haven't read this fanfic in a few years.

Thank you for your help!
