Alpha and Omega
Chapter 1
Two Omega twins Castiel and Caileigh have been on their own since they were teens. Their family pack was abusive and they ran away. They work in the same bookstore, Caileigh in the books and Cas in the cafe where he does all the baking. They live in a small one bedroom apartment where they share a bed for comfort. They walk to work together and always look out for each other, even guarding and caring for each other during heats.
One night while walking home from work, they are surrounded by a gang of betas. The six aggressive males surround them. The twins put up a fight, but still get dragged into an alley. Suddenly two Alphas attack the betas, breaking bones and bloodying their faces until they all take off.
The Alphas turn to face the Omegas they have just rescued, their blood is thundering in their ears, Alpha instincts screaming at them. Having just fought and spilled blood in defense of an Omega, their instincts are screaming at them to claim the Omegas for their own. The Omegas can smell the possessive arousal and aggression in the scent of the tall and powerful Alphas facing them, the blood of the betas still on their knuckles and mouths. The Omegas sink to their knees on the ground under the weight of the Alphas presence, desperately clutching each other's hands, trembling with fear.
The Alphas can smell the rank fear from the Omegas, heightening their instinct to protect, cutting through the haze of lust and the urge to claim, to mate. It was a testament to their strength as Alphas that they can resist the urge. Dean tells Sam to go guard the entrance to the alley as he is the tallest and biggest of the two of them. Dean got down on one knee in front of the pair, taking in their raven black hair and dark blue eyes. Speaking softly, "I'm Dean, and this is my brother Sam. We're not going to hurt you, no one's going to hurt you."
The male Omega shyly looked up at the beautiful green eyed Alpha, only briefly making eye contact, "I'm Cas and this is my sister Caileigh."
"Nice to meet you," said Dean, "Are you hurt, do either of you need to go to the hospital?"
"N-no, I don't think so," responded Cas shakily.
"Okay, then let's get you up," suggested Dean gently while holding his hand out to Cas, who hesitantly placed his hand in the Alpha's. This elicited a growl from the female Omega, startling Dean and causing Sam's head to whip around, pinning his brother with a glare. Sam rushed over to kneel in front of his Omega, unable to ignore her distress.
It was Cas who calmed his sister, "It's okay, Dean's not hurting me". Dean helped Cas to his feet, putting his arm around the slightly smaller man for support.
When Caileigh tries to stand, she whimpers as she puts weight on her right leg, her knee is badly scraped and bruised. Sam immediately picks her up, cradling her in his arms. This elicits a protective growl from Cas. Dean tried to sooth Cas but he only calmed down when Caileigh reached out to stroke his arm.
Sam looked down at the beautiful blue-eyed Omega in his arms, "Our car is just over there, we'll get you home safe."
Caileigh looked up at Sam, giving a shy nod to the very large Alpha holding her. She knew that she should still be afraid of him, but being held against the solid wall of his chest somehow made her feel safe and secure. The Omega in her was responding to the confident assurance of his Alpha, and judging by the way her brother appeared to be melting into Dean's side, she wasn't the only one.
