Chapter Text
Looking at Sam, Dean raised the bottle of beer to his lips and took a long sip from it. He could feel heat pooling in his belly as he eyed his younger brother. His mind screamed Alpha as he eyed Sam and his body certainly reacted as if his brother was his mate. Sam had filled out from the lanky teen his brother had once been to the tall and broad-shouldered alpha Sam had turned into over the past few years. Sam was a few inches taller than him which was unnerving at times since he was the older of the two. Sam had also presented as an alpha like their father, whereas he had presented as an omega, much to their father, John’s amazement. Their father had also told them while they were young pups that he expected Sam to present as an omega and him to present as an alpha. Somehow not only his father but whatever gods were watching over them had gotten things incredibly wrong. While he wished his father had been right about him presenting as an alpha, he didn’t really see anything wrong with being an omega. He was still a great hunter, actually better at hunting the supernatural than a lot of alphas they had met over the years. He attributed some of his skills to their father, but he also knew the skills he possessed were from years of honing his abilities to shoot a gun, fighting with a knife, fighting in hand-to-hand combat when there wasn’t a weapon available, and just his natural prowess. Sam had a similar set of skills but his brother was also book-savvy whereas while he was good at researching, he just preferred to leave that to Sam since he found it to be boring while his brother enjoyed it.
Lowering his bottle, he placed it on the table and tilted his head as he continued to look at Sam. He noticed how the muscles in Sam’s neck moved as Sam tilted his head back and took a sip from his own bottle and the muscles in Sam’s arm seemed to flex and bulge out from the hem of his t-shirt. His eyes traveled from Sam’s arm across Sam’s broad chest and down to Sam’s tapered waist before he turned his green eyes up to Sam’s face, taking in Sam’s hazel eyes and his angular features. Sam would make any omega or beta happy when Sam finally decided he was tired of the lifestyle they led and wanted to settle down with a mate. He felt a sudden flash of sadness, like a stab to his heart, at that thought. He tried never to dwell on the idea that Sam would eventually pick a mate, one that wasn’t him, and leave him. But that was just the way things were and he knew it. He wasn’t worthy of being an alpha’s mate in general since he liked his independence, and he knew Sam didn’t want him as his mate. It was fine for Sam to knot him from time to time when they needed to let off some pent-up energy and it was helpful to have Sam around when he was in heat. But he knew where he stood with Sam in the life they had created for the time being. He didn’t need to seek out an alpha-for-hire or have a chance encounter with an alpha who suddenly decided that he wanted to mate and claim him. No thank you to that as far as he was concerned because the only alpha he wanted was the one he would never have as his mate and that was Sam.
Forcing those thoughts aside, he licked his lips. He felt the heat pooling in his belly beginning to move, to course through his body and he knew what that meant. Not only did he want Sam, but his heat was also starting. He had tried to push through it once not wanting to bother Sam with his needs, but Sam had cornered him, convincing him that it was better to let Sam help him through his heats than a stranger. He could still remember that conversation as if it were yesterday. He had been pacing the confined motel room they had been staying at just after Sam left Stanford to join him in the search for their father. He hadn’t even been paying attention to how close he was to his heat. He had overlooked the telltale signs. How he’d become increasingly irritable and how his skin felt too tight as if it were stretched across his bones. He hadn’t noticed how flushed his normally pale skin had become or how dull-eyed he was. But Sam had noticed. Which wasn’t something he had been counting on, but he should have because Sam seemed to notice everything.
Before Sam, he used to lock himself away with a knotted dildo until his heat passed and those times alone had been painful for him; feeling so alone, unwanted, and empty. Their father knew enough not to venture too close to him when his heat was approaching, not that he would allow their father to touch him let alone knot him. Hell, he had fought off several alphas and he would have fought off their father if he had needed to. But Sam had been another story. He had wanted Sam from the time Sam had presented as an alpha. He wasn’t sure if it was because Sam was an alpha or if it was because he loved Sam with his entire being as to why he wanted Sam as his mate. He knew instinctively that Sam would never betray him or hurt him, and Sam would never claim him against his will.
“Dean, let me help you,” Sam said as he stood up from the queen-size bed he had claimed as his.
“I don’t know what you’re talking about,” Dean responded and then he had snarled in an attempt to end the conversation he didn’t want to have with Sam.
“Dean,” Sam breathed out and reached out to Dean, placing his hand on his brother’s shoulders, forcing Dean to stop pacing the motel floor and look at him. “Let me help you through your heat.”
“What the fuck?” Dean responded, pulling away from Sam’s touch. “You can’t be serious. You’re my brother…”
“And I’m also an alpha. It’s not unheard of for an alpha sibling to help their omega sibling out during their heat if another suitable alpha isn’t available. Unless… unless you have someone else to help you…” Sam had been uncertain of what Dean’s response would be. Up until now, he had no idea how Dean had dealt with his heats. He seriously doubted Dean would have allowed their father to touch him. So there were only two possibilities, Dean would have hooked up with some random alpha while he was in heat or Dean used a knotted dildo. The alpha in him truly hoped it was the latter because the idea of another alpha touching Dean was enough to make him see red. The thought of Dean with anyone other than him set him on edge. Even when he’d been away at Stanford, he hadn’t liked the idea of Dean being so far away from him. He had begged Dean to come with him, but Dean had refused, giving him the line that they couldn’t both abandon their father. He had tried to make a life for himself without Dean but he had only been going through the motions. He knew that and so did Jess. He had tried to make their relationship work, but it was at the end of its life by the time Dean had shown up needing his help to look for their missing father. He had never been happier to see Dean, even though he knew Dean had been around campus a few times checking up on him. He’d never bothered to say anything to Dean knowing that his brother would have just denied that he had been to Stanford before.
“Christ, Sam, no… never.” Dean could feel his already warm skin beginning to burn from his embarrassment. He couldn’t believe he was having this discussion with his alpha brother. “I can’t ask that of you…” He knew he should have left the room, that he should have gotten himself another room, but Sam’s alpha pheromones were clouding his mind and impairing his judgment.
“You’re not asking me to help you out. I offered. At least this way you know you’re safe with me. I won’t go all alpha on you and try to claim you.” Sam offered Dean a tight smile. He knew what he was proposing was something they had never talked about before. Up until this point he had only ever dreamed of knotting Dean but seeing how his brother was acting, muddled and irritable, he knew he needed to do something to help Dean out. He could only imagine how hard it was for Dean to deal with a heat without an alpha to help him through it, and a knotted dildo didn’t count in his opinion.
Dean's brows furrowed at Sam’s words. So, Sam was willing to knot him in order to help him through his heat, but Sam didn’t want to claim him. He felt equal parts relieved and sad with that knowledge. Sam didn’t feel the same way he felt. Knowing how Sam felt he forced himself to lock away his desire for his alpha brother to claim him. He could have Sam help him through his heat this one time and then he’d make sure to never let it happen again. The next time he was close to his heat he’d lock himself away until it was over. “Yeah… yeah, okay, Sam,” he agreed, and then they were both stripping out of their clothes, and then they were on the bed in a tangle of limbs. The first time Sam had knotted him had been mind-blowing for him. He had expected pain and to be used without feeling any pleasure, but Sam had been gentle when knotting him and Sam had made sure he’d climaxed.
That night so long ago was the start of something Dean had no idea how to label. He knew he was Sam’s older brother. He knew Sam was an alpha and he was an omega, but did he mean more to Sam than just some omega Sam helped through his heats? He tried never to let himself dwell on the obvious that he was unmated yet smelled of an alpha. Sam’s scent helped to keep unwanted alphas away from him. And if he was being truthful with himself, he liked that no other alpha tried to touch him because he smelled of Sam. He liked having Sam’s scent on his skin and clothing. It was comforting. It made him feel at ease, but it also made him want more. Sam’s scent called to him. Sam’s scent screamed of Mate to him. And every day it reminded him of what he would never have. He would never have Sam as his mate.
Picking up his beer bottle, he raised it to his lips and drained the last of the amber liquid before placing the bottle back down on the table. Licking his lips, he looked over at Sam, watching as Sam raised his right hand and pushed his chestnut-colored hair out of his eyes. He would never say it out loud, but he loved running his fingers through Sam’s soft locks. He also loved teasing Sam mercilessly over his hair and the hair products Sam used to maintain his hair. That thought caused him to smirk. Teasing Sam was just something he was used to, having done that since they had been young pups. Nowadays, Sam just took his teasing in stride but when they had been younger his teasing of Sam would end in a fight between them. He regretted the hurt feelings he had caused Sam while they were growing up. He had learned over the years what he could and couldn’t tease Sam over. He never brought up Stanford anymore. That time away from Sam had been painful for him. He had missed the hell out of Sam. He had gone to Stanford on more than one occasion to check up on Sam, wanting to make sure his younger brother was safe and happy. He had seen the beta, Jess, Sam had been dating. It had hurt to see Sam so happy with her. It had also hurt to see how Sam grieved for her after her death. There were many nights he lay awake wondering if things would have been different if he hadn’t shown up in Sam and Jess’ apartment. Would she still be alive if he had never pulled Sam back into his life to help him search for their father? Would Sam be a lawyer by now living the American dream with Jess as his mate? Would Sam and Jess have pups of their own by now? Would Sam have been happier if he had never shown up that night? Did Sam regret going off with him? Did Sam wish that he had never forced his way back into Sam’s life? Was he the cause of whatever unhappiness Sam carried around with him? Was that the reason Sam only knotted him but never tried to claim him? The sound of Sam’s voice pulled him from his thoughts.
“You want another beer?” Sam asked, tipping his bottle at Dean’s bottle sitting on the table.
Dean looked at Sam and then down at his empty bottle. Did he want another beer? “No, I think I’m gonna turn in for the night.” He didn’t want another beer. What he wanted was Sam. He knew alcohol would only fuel the desire he was feeling for Sam and in the wake of his oncoming heat, he didn’t want to tempt fate. He didn’t want to end up begging Sam to knot him. He would wait to do that when he was in the throes of his heat. That way he wouldn’t feel embarrassed and he could pin his desire for Sam to knot him on his heat. Plus, he still needed to take his birth control before he went to bed. There had been a few days recently that he had forgotten to take it and he knew with his heat coming on he needed to make sure he didn’t forget to take his pill again.
“Come on, Dean, it’s too early to turn in. It’s not even ten o’clock. We don’t have a case to work on. Let’s just hang out, have a beer or two more, and maybe watch a movie. I’ll even let you put on Die Hard. I won’t even make a comment about how unrealistic that movie is.” Sam wiggled his eyebrows at Dean in an attempt to entice his brother. When he saw the dubious look on Dean’s face he knew he needed to turn on the charm of what Dean called his puppy dog eyes. “Please,” he asked in earnest, giving Dean the look he knew his brother could never say no to.
Dean knew what his brother was attempting to do. Sam was trying and succeeding at wearing down his defenses. If Sam hadn’t given him the look that made him weak in the knees he would have been able to say no to his brother. But Sam had to give him those damn puppy dog eyes and he was sure Sam knew what they did to him. “Fine,” he sighed and watched as a dimpled smile split Sam’s face.
“Yes!” Sam croaked happily. He had won that small battle of wills between them. “You get the movie started and I’ll grab two more beers. Use my laptop and I’ll join you in the bedroom in a minute,” he said as he turned and made his way into the kitchen to grab two more beers.
Dean watched as Sam disappeared from the room before grabbing his brother’s laptop and making his way down the hallway and into his room. He thought it was a little odd that Sam had suggested they watch the movie on Sam’s laptop while in his bed. Usually, they would make themselves comfortable in the movie room they had created for themselves a few months ago. They had done their best to make the bunker their home and he had been pretty happy with the outcome. Trying not to put too much thought into anything else, he kicked off his boots, climbed onto his bed, got comfortable, pulled up Die Hard, and waited for Sam to join him so he could start the movie.
He looked up when he heard Sam clearing his throat to see Sam standing in the doorway to his bedroom, the bedroom they shared from time to time, looking at him. Sam seemed to have an odd look on his face, one he couldn’t figure out. Why was Sam looking at him as if Sam had never seen him before? It was a little unnerving but he did his best to ignore the look on Sam’s face, choosing to focus on what Sam was holding in his hands. “Is one of those for me?” he asked, pointing to one of the beer bottles Sam was holding.
Sam looked from Dean to the bottle he was holding in his right hand. “Ah... yeah,” he confirmed as he crossed the room to the bed, and handed Dean one of the bottles of beer before climbing onto the bed next to his brother. “Okay, roll ‘em.”
“Just remember, you promised not to make any comments,” Dean reminded Sam as he started the movie. Halfway through the movie, he felt Sam’s hand on his thigh and Sam’s larger body pressed up against his. Then, Sam was pausing the movie and moving the laptop out of his hands, and placing it on the nightstand. “Sam…” he started to say only to be silenced when Sam surged forward and crushed their lips together. He moaned into Sam’s mouth, enjoying the heated kiss as Sam slipped his hands under his shirt. Any previous thoughts he had of taking his birth control were forgotten as Sam began to tug his shirt over his head. “Sam,” he whimpered when Sam pulled away from him. At first, he thought Sam was teasing him only to realize Sam had pulled away from him in order to get undressed. He made quick work of the rest of his clothing, tossing it to the floor to join the pile Sam’s discarded clothing had created. As soon as they were both undressed, he found himself in Sam’s arms, their limbs tangled together, their bodies pressing against each other. He could feel how hard they both were and he could feel the slick he was producing leaking down his thighs.
Sam broke contact with Dean after kissing his brother until they were panting for air. “Roll over onto your stomach,” he growled, wanting Dean to present himself so he could knot his brother.
With his breaths coming in shallow gasps, Dean rolled over so he was on his hands and knees. They both knew it was the best position for him to be in when Sam knotted him. He shivered from the cool air against his heated skin and then gasped when he felt Sam’s body between his legs. He groaned when Sam’s fingers rubbed over his sensitive rim before delving into him to work him open. He whimpered when Sam withdrew his fingers from him, only to grunt when he felt the head of Sam’s cock pushing past his rim. He knew Sam had sensed his heat coming on and that was why Sam had offered to be with him but at that moment, feeling Sam splitting him open, he didn’t care. He wanted Sam to knot him.
“Fuck… Dean…” Sam moaned when he was fully sheathed in Dean’s tight channel. He set his teeth to the back of Dean’s neck. He could feel the urge to bite down on Dean’s neck, breaking through the sensitive skin, as his canines elongated. He fought against the desire to claim Dean as his mated omega, knowing that Dean preferred to be an independent omega, one who didn’t want an alpha mate. Dean enjoyed being able to make his own choices without having to answer to an alpha, especially one he would be mated to. A feeling of sadness flooded his body at that thought. If given the chance he would happily claim Dean as his mated omega. He loved his older brother with all his heart. He would tell the world how proud he was that he was Dean’s mate. How he was proud that Dean had allowed him to claim Dean as his. He would never take Dean for granted. He would never demand that Dean give up what he loved - hunting the supernatural - to settle down as a mated omega, produce pup after pup and raise his pups. If Dean chose never to have a pup he would be on board with that decision. He loved what he had with Dean. He wasn’t about to ruin that by being the typical alpha male and making demands of Dean. The only thing he wanted to change in what he had with Dean would be that Dean was his and he would be Dean’s. They wouldn’t just be brothers, or an alpha and an omega, they would be a mated pair. Forcing that thought from his mind he focused his attention on Dean and giving Dean what his brother needed while Dean was in heat.
“Sam,” Dean moaned as his brother thrust into him hard and fast. He clawed at the mattress trying to find purchase as Sam slammed into him moving him up the bed. His breaths were coming in hard gulps as he gasped at the feeling of taking Sam’s cock. He felt Sam’s hands on his hips, Sam’s fingers squeezing and digging into his flesh, and he knew he’d be sporting bruises in the morning. He grunted when he felt Sam’s knot being forced past his already sensitive and stretched rim. He felt Sam’s cock pulsing in him sending him over the edge as he came calling out his brother’s name. Before his body went limp from his orgasm, he felt Sam wrapping his arms arm him and maneuvering them so they were lying comfortably on their sides. They would be tied for a while, and he liked the idea of being wrapped up in Sam’s muscular arms. He felt a kiss on his neck making his heart slam against his ribcage as Sam then licked over the spot he had just kissed. It felt so intimate and heartbreaking at the same time knowing that would be the spot on his neck where a claiming bite would be if Sam or any other alpha claimed him. He squeezed his eyes closed willing away the pain he was feeling over Sam not claiming him and did his best not to give in to his emotions. He heard Sam whispering to him to try to get some sleep and the only response he could give was a nod of his head fearing that if he spoke, he would end up begging Sam to claim him and he would never do that. He would never put himself in the position where he had to beg to be claimed and he would never put Sam in the position of having to deny him what he wanted. Keeping his eyes closed he did his best to relax against Sam’s body, feeling Sam’s cock pulsing in him as he drifted off to sleep.
As Dean lay asleep in his arms, he gently moved trying not to disturb his brother while they were still tied together. He trailed his fingers over Dean’s arm and down Dean’s stomach until he was able to press his hand against Dean’s toned stomach. For a moment he allowed himself to imagine what it would be like to have Dean as his mate and what it would be like to hold Dean while Dean was carrying their pup. He could almost imagine what it would be like to feel the movement of their unborn pup as it grew within Dean’s body. He liked the idea of having a pup of their own. Would they continue with hunting, or would they leave that world behind? If they did leave the hunting world behind, would they still continue to live in the bunker or would they settle someplace else? He did like the idea of having a cabin someplace away from others, a place just for them where there was green space that allowed them to breathe. A safe place where their pup could play without them fearing for the pup’s safety. He didn’t really care where they ended up as long as he had Dean by his side as they cared for and raised their pup together. He would never leave the caring of their pup solely to Dean. He didn’t want that and he knew Dean would never go for that either. While he was an alpha, he wanted to be involved with raising their pup and caring for his family. He knew it was only a daydream, one he had to force aside. There was no way that Dean wanted him as anything more than his brother. He had been the one to coax Dean into allowing him to help Dean through his heats. At first, Dean had fought him on that subject but eventually, Dean had given in, seeing the benefit of having a willing alpha who wouldn’t force Dean into a mating or even bring the subject up every time Dean was in heat or wanted to be knotted. He needed to try and get some much-needed sleep while he was still tied to Dean before Dean woke up and possibly needed to be knotted again.
