Chapter Text
When Dean Winchester went in for his exam at twelve both he and his father were confident about one thing - he would be an Alpha. So when the doctor smiled softly and said the word, "Omega" Dean's world completely crashed around him.
His father had roughly patted him on the back and told him it was alright. Sam launched into a speech about Omega's rights changing and some gibberish about laws and everyone being equal but Dean didn't hear any of it. To say he was depressed was an extreme understatement. He was the oldest child. He should be his father's pride and joy and Sam's protector. How could he be any of that when society looked at him like a bitch to be tamed?
It took Dean several weeks to come to terms with his genetics but once he did he owned it. Yeah, so what if he was an Omega? That just meant he could take down any prick that messed with him and carry a baby IF he ever wanted to. However, he promised himself he would never take an alpha as a mate. He would never be submissive to anyone or be their property. He would never be forced to leave his family.
That all changed the day Castiel Novak came to his school. Dean had been doodling on the corner of his notebook when a chill crept up his spine all the way to his neck. Around him the air had turned sweetly thick, causing warmth to gather in the pit of his belly. Immediately his head snapped up and he found two blue eyes watching him carefully. Their homeroom teacher introduced the student as, "Castiel Novak" and the name somehow sounded like music to Dean. She told him to pick any seat he wanted and quite rigidly the boy walked towards the back of the room, sitting a row over from Dean.
That's when everything went to hell. It was well known that most Omegas hit their first heat about a week after their 15 birthday. Dean, who was only 14 now, didn't think he should be expecting this horrible curse for another year. However, he knew exactly what was happening because he had thoroughly read up on the subject, and Sam had spent every waking minute coming to him with facts and ways to make the process easier on his mind and body.
Where the fuck was Sam now with his hippy, yoga mambo jambo?
Dean barely managed to excuse himself to the bathroom before the heat hit him full force bringing him to his knees in the empty hallway. His hole was leaking and throbbing, and he desperately wanted it to be full. He had never even put a finger inside himself before so this was all new to him.
A rough voice behind Dean made him whimper loudly.
"Are - are you okay?"
Dean shook his head. "Go away."
His snapped up in time to see Castiel Novak staring at him with ocean blue eyes that were growing darker by the second.
"Oh fuck," the boy whispered as he slammed his fist into the locker. "Fuck."
"What?" Dean demanded, stumbling to his feet and letting out a low whine as more of that liquid streamed out of him.
"Fuck - I'm -"
That's when Dean smelled something so sweet that his mouth actually began to water. It smelled like apple pie, freshly cut grass and fire wood. He knew in an instant it was coming from Cas. It was the smell of mate. Of Alpha. An Alpha was who about to lose control.
"Are you rutting?" Dean spat out, voice shaking.
Cas let out a low growl, grabbing Dean and slamming him into the wall bringing their faces inches a part.
"What's your name?" he demanded.
Dean hated that his first instinct was to obey. "Dean Winchester."
"Dean," Cas repeated thoughtfully and then he was pressing his lips to Dean's roughly.
Dean, who had never been properly kissed before, melted into the touch immediately. He grabbed at the alpha anyway he could, trying to pull him closer. Cas raked at his sides with long finger nails that had Dean moaning like those half plastic girls from cheesy pornos. Cas pulled away to lick a stripe across his neck.
"Mine," Cas growled roughly. "My omega."
These words snapped Dean back into reality. He immediately began shoving Cas away from him. "No, I'm not your anything! You aren't my alpha!"
Cas gripped Dean roughly. "I am," he insisted. "I can feel it in my fucking soul. You're mine."
This brought spots of red in front of Dean's eyes. He shoved at Cas again and yelled, "Fuck you."
He turned away to leave, immediately feeling empty and cold. Cas did not give him much time to stew in this feeling though because he was grabbing Dean roughly and slamming him into the locker.
"Mine," Cas repeated, eyes almost completely black.
"Look you fucking knot head -"
Cas let out a ferocious growl, grabbed Dean's hair roughly and twisted his head until his neck was exposed then he leaned forward and bit down on his skin.
"NO! STOP! HELP! HELP!" Dean cried out, tears streaming down his face.
Teachers stormed the hall after that, running at the pair as fast as they could. However, the deed had been done. Castiel had marked Dean as his own.
Dean had blocked out most of the memories after that. Teachers restrained Castiel immediately, pulling him away. He remembered people covering their mouths in horror and saying, "Mated at 14 years old. I've never heard of such a thing."
His dad was called to the school to pick him up. John was furious, demanding to know how it happened and why the students weren't being kept safe. Sam had grabbed Dean around the middle and burst into tears, saying that he didn't want him to go with Castiel. Dean's entire world had stopped spinning then. He had been mated by someone. He belonged to someone. He had to do whatever Castiel wanted or said. He was now someone's property. He would never be able to pick his lover. All decisions had been stolen from him. The entire process was made even worse by the fact that his skin was still crawling from his heat.
John had dragged him and Sammy out of school, telling them to pack a bag when they got home.
"But don't I have to go with him now?" Dean asked numbly. "My - "
He couldn't even say the word alpha for the fear of puking.
"What?" John asked incredulously. "You really think I would make you go live with that fucking knothead? No, you are a Winchester and you are staying with us. But we're not staying here. That boy will come and so will his family. They will demand you go with them and I don't want to go to jail for killing a child but I sure as hell will. Now, pack your things. We're going to Bobby's."
And they did. For four years they stayed at Bobby's happy and content, free of any fears of Dean being taken away. That's why Dean was finding it so hard to believe that he was currently standing outside of the Novak's large house with his father and Sam, about to see his mate again.
