Lucifer's Pet.

Eighteen years ago, a mother sacrificed her baby to Lucifer in return for the baby's safety. The mother died during birth, Lucifer accepted the sacrifice, and he'll back to claim what he owns. Nova, a depressed half-wolf, half-human girl. On one lonely night she decides to end things, she'd end up in hell, but even real hell can't be as bad as her life. That until the king of hell scolds her, and tan her bum claiming her as his. This is a ddlg/cgl/SFW story, be warned! Apologies for any misspelling or grammar mistakes.
