Oral Fixation - Stiles Stilinski - 18- Omegaverse AU

Derek Hale thought he was the only Hale to survive the fire, but like always, it seemed like he was wrong. Peter survived, and so did Laura and Cora. Imagine his surprise when he sees his baby brother face to face after all these years. Derek didn't think if his brother survived that, they would ever be at odds, but that turns out to be the case when Honor sets his eyes on a certain hyper-annoying Human Omega that Derek has a sweet spot.
