Summary: Written for this spnkink-meme prompt. Omegas aren't born that way. They're made. Every child born to an Alpha/Omega parents is born Alpha. Daily exposure to the hormones present in Alpha semen turns an Alpha into an Omega. Also, Alphas can't stand to have the competition of other Alphas around and will do their best to convert the alphas around them (like their siblings) into omegas or failing that, kill them.
Modern families, to prevent their teenaged children from raping or killing their siblings, usually pick one, most often the oldest, to remain Alpha. The rest of their children, they convert to Omega from a young age, using artificial hormones in pill form. It's seen as the civilized and kind thing to do.
Some traditional families, like the Winchesters, believe the old ways are best and that an Alpha is stronger if he actually has to work for it. These parents not only allow their children to do their best to convert their siblings, they encourage it. Dean has always known that he 'should take care of' Sam I.e. kill him or forcibly convert him to Omega. It's his place and right as the older brother. He just can't do it though. The day he finally makes up his mind to do it, he finds himself flat on his back, legs spread for his younger brother.
Big Brother Omega
The hunting trip had been a bust, but being able to spend time with his alpha father alone was worth it. Seventeen-year old Dean knew his father was right; it was time to assert his alpha status over his younger brother before one of them felt the need to kill the other.
But Dean really loved his brother, and despite everything he couldn’t bring himself to hurt his little brother. All of his life he’d taken care of him, in the way an omega would care for his children, he bathed him, cooked and fed him, and even held him while his younger brother cried after being hurt.
Omegas were made. And in the end Dean didn’t want to be an omega… someone’s bitch. So it was time to assert himself and this meant turning his brother into the omega bitch he didn’t want to be. Most families used synthetic means to make their younger children omega’s, devices captured the alpha parent or child’s essence and it was injected into the younger children’s drink and food, or even into their blood stream. Most transitions into omegas was done peacefully now. But not for traditional families like the Winchesters.
The Winchesters had a long history of being traditionalist. And in those families, one sibling, or sometimes the parent itself, would force those weaker alphas around him to take control of their brothers and force them to take his cum… orally or anally, even rub it into their skin. Dean was expected to physically over power Sam and seduce or even rape him. And after a week of this, his brother would become an omega, his omega if he wanted him. Dean knew he would want his brother to be his alone, never to share.
John dropped his son off at the door to the cabin where they had left the thirteen-year old Sam, patting his knee and told him to “go get him, Tiger. I’ll be back in a week. Make me proud, Deano.”
Dean sighed and paused at the door, he took a moment to psych himself up for what he had to do.
The cabin was dark as he entered, just the light coming from under the door to Sam’s bedroom. Dean tossed his bag down on the floor and walked across to the closet where Dad kept his restraints. That would be easiest, hold Sammy fast and securely while he did what he had no choice but to do.
Pulling the door open, Dean stared confused at the empty closet. “What the…?” Dean started before a hard body smashed into him, causing his head to spin.
Dean struggled against the attacking force, despite his head spinning but didn’t feel the restraints around his wrists until it was tight and he was attached to the handle of the closet.
Hands tore at his clothes, ripping them from his body and leaving him exposed and naked. Dean’s instincts took over and he started to try and fight off his attacker with his legs, kicking at him. He worried that somewhere in the cabin, Sammy was held prisoner of this man as well.
A hand covered his mouth, and a lukewarm, salty substance was forced into his mouth and shoved down his throat. Dean tried to spit it out, but a hand squeezing his nose left him no choice but to swallow. It took a moment for Dean to realize what he’d just swallowed: cum.
The attacker pushed his face close to Dean’s as he sputtered on the swallowed cum. “So you finally decided to try and take me, huh, Dean?”
Dean jerked as hands pushed his legs apart and two wet, sticky fingers pressed roughly into his now exposed asshole. “Sammy? Please… stop, you’re hurting me!”
“But this is what you were going to do to me,” the younger teenager’s voice wobbled as it broke, showing his young age. “You were probably going to coat your fingers in your come like I just did and shove it up my ass. I’m just beating you to it. You’re going to be my bitch. And when Dad gets home, won’t he be surprised to find you’re the one with the pussy.”
Dean continued to struggle as the truth of those words wasn’t lost on him. When two fingers became three and brushed against his prostate, Dean couldn’t help but moan despite the pain.
“See, my cum is already working!” Sammy laughed as he thrust his fingers in hard again, spreading them wide to stretch him out. “You’ve been drinking my cum for days now and you’re already half a bitch. Can’t believe Dad didn’t notice, I’ve been putting my cum in your drinks for a while.”
Dean felt Sam’s fingers pull out and his legs were hiked up on Sam’s shoulders. “I can’t wait till you have a pussy here for me to fuck into, and leave my puppies there. You’re going to give me lots of omegas, because I won’t wait like Dad did for his weak ass son to be a man.”
Dean screamed as his brother’s huge cock was shoved in past his resisting ring of muscles. He couldn’t remember his brother’s cock being so large but than he had avoided perving on his baby brother for a while now.
“Fuck, I knew you’d be a fucking virgin!” Sam groaned as he made another hard thrust till he was more than halfway in. “You’re like a vice around me, I may just keep my cock buried here for the entire week, just filling you with my cum till it spills out your ears.”
Dean felt tears streaming down his face as his baby brother thrust one more time till his balls slapped against his ass. “Sammy, please!”
The smack across Dean’s head was a little shocking. Dean could feel Sam’s knot starting to swell, it tugged on the rim of his hole, pulling painfully as it stretch Dean further. “Don’t call me that anymore. You call me Sam… or Alpha! I’m going to just call you bitch.”
Sam’s pace was hard, each thrust seem to split Dean further in two, until Sam’s knot forced its way into his hole and started to pump what seemed like gallons of cum into Dean’s channel.
Dean let out a wail. It was like he could feel his body starting to accept his new status. It was no longer hurting quite as much. In fact it was starting to buzz his body with pleasure and his cock was starting to stir to life and harden. Sam’s knot was pressing and rubbing against his prostate as his younger brother rocked through his orgasm. Dean let out another cry as he had his own orgasm, shooting onto his stomach.
Dean felt his head swimming as he laid back and closed his eyes, tears still on his face. Sam’s body stilled as they were locked together. He rested his head on Dean’s shoulder as exhausting pulled them both towards sleep. “You are so beautiful, Dean, and you’ll be my beautiful omega.”
----
Dean awoke an hour or so later, some how in his sleep, they’d been moved to their father’s large bed and he was once again restrained against the bed, this time by both his hands and his ankles. He looked around the empty room and tried to figure out a way to escape.
A noise at the door pulled his attention as Sam entered carrying sandwiches and some of their dad’s beer.
“Oh good, you’re awake,” Sam set the dishes down on the bed next to Dean. “You need to eat. Everyone knows your body is going to need extra energy as it changes and you grow a vagina.”
Dean looked skeptical as Sam held out the beer with a straw in it for him to drink. “Come on, Dean, you need your strength.”
Dean leaned forward and took a drink as his stomach growled. “Thanks,” he mumbled. As Sam fed him one of the sandwiches and a beer, Dean’s face burned with humiliation as he was treated like a child.
When the plates and dishes were moved, Sam scooted up next to him. “How did my cum taste?”
Dean looked at him in horror.
“Oh yeah, you didn’t think I would stop dousing you, did you?” Sam grinned at him, his fingers trailing over Dean’s full lips. “Besides, soon you’ll be getting it strait from the source. I can’t wait to feel your lips around my cock, drinking me down.”
Sam moved to kneel in front of Dean, his hard cock waving in his face. “Open up, my bitch.”
Sam’s hands threaded in Dean’s short blondish hair. Sam pulled Dean’s head back and guided his hard cock into his mouth, thrusting into the warm wet heat.
Sam groaned as he thrust repeatedly into him, he toyed with the idea of knotting his brother’s mouth but in the end decided not to, instead pumping his cum down his brother’s throat, groaning his brother’s name.
Sam slid out and reached down to catch the cum dripping out the sides of his mouth to push it back in. “Lick me clean, bitch.”
----
Two days passed with Dean only released long enough to use the bathroom and showers, usually those trips ended with Sam’s cock up his ass once again. Dean was fixed again to the bed, his legs free, but he had long since given up fighting his brother.
Sam grinned at him as he moved down his body, touching Dean as he went. When he got to his pelvis, Sam stroked his cock a few times. “I think its already getting smaller,” Sam said looking at it critically.
Pushing Dean’s cock and balls out of the way, Sam laid on the bed to finger over his perineum and balls. “Wow, didn’t know it would start happening this fast. Do you feel that?”
Dean tried not to panic but he did, it felt like he was opening up to Sam in a space he didn’t before.
“You’re getting your pussy already!” Sam sounded exited as he continued to push against him. “I’m going to be putting my cock in here really soon!”
Dean shook his head, tears again filling his eyes. “I’m glad someone is happy.”
“Oh come on, you’d have been happy if our places were reversed. I’m sorry you just weren’t fast enough… or were just too soft hearted. Makes me think you kind of wanted this to happen.”
“Why would anyone want this, that’s why I couldn’t bring myself to do it to you,” Dean said bitterly. “I wish you’d have just killed me.”
“I couldn’t kill you, Dean,” Sammy said coming back up to stare into his green eyes. “I love you.”
Dean looked shocked as his eyes locked with his brothers. “You what? You love me?”
“I always have,” Sam said leaning down to kiss his brother. “I would want you even if our bodies weren’t wired to change each other.”
Dean blushed and turned his face away, how could he admit that he’d always loved his brother too. If he had to be anyone’s bitch, he’d want to be Sam’s.
----
By the end of the week, John pulled up in front of the cabin, shutting the Impala off and climbing out. It would be good to finally have things normal in the house. Three alphas under one roof was one to many, maybe even two too many but he needed at least one alpha son.
Turning the handle to the cabin, John smiled as he heard grunting from his bedroom. He’d yell at them later for messing with his bed. Right now he’d wanted to go congratulate Dean for his new position, and check out his new omega son.
Pushing the door open John’s mouth dropped at the sight in front of him. Dean was on his hands and knees, his ass high in the air as Sam pumped himself in and out of Dean’s… vagina. Dean moaned and screamed in heat, his legs shaking through an orgasm.
“Welcome home, Dad,” Sam looked over to grin at him before slamming his knot into his omega brother’s vagina, locking them together as he knotted him. “I hope you’re not disappointed.”
John stared at him for a few moments before grinning at his youngest. “Nope. Good job son. Feels good to have an omega bitch under you, doesn’t it?”
