Chapter Text
***************
You don't know what life was like before the Winchester Pack. Your family was rogue, they didn't belong to any Pack, which made you all more vulnerable. Your family’s home was attacked while your mom was pregnant with you. Your father was killed but he managed to save you and your mom, giving her a chance to escape. She eventually found a place to hide in the forest before she passed out, turns out she was in Winchester territory.
When she awoke she was in the Lodge, a huge stone house with multiple hearths and even more rooms, which is home to the Winchester Alpha and his family. She was later informed that she had been found during the Moon Run by the Winchester Alpha himself. She was attended by Beta midwives and the Pack Omega. Mary Winchester was a sweet and charming female. She had just given birth to her second son, Samuel. Mary spoke with your mom every day. Sometimes she would even bring her two pups, Sam and his older brother Dean to visit. Dean was an alpha and heir to the Winchester Pack. He was inquisitive and asked your mom endless questions about you. Mary assured your mom that he was just as curious about her pregnancy with Sam. One day while they were all visiting Mary asked,
“Dean, sweetie, why do you ask us so many questions about our pups?”
“Mom, they’re gonna be my Omega mates someday. I wanna know everything about them.” Mary and your mom laughed at how ridiculous they thought Dean was being. The serious look on Dean’s face didn't help his argument either.
Mary became your mom’s closest friend. Within a few months, your mom went into labor and she was there to help every step of the way. Your mom secretly hoped you’d be omega, and maybe a potential mate for one of Mary’s sons. Mary didn't get the chance to find out what gender Sam would be before she died, only a few months later. It was devastating for everyone. Your mom helped with Sam and Dean, even acting as a wet nurse to Sam, and spent much of her time in the Lodge. Eventually, you became a sister to the boys, especially Sam.
It was the boys who helped you the most when your mom passed away when you were 6. They were the only ones who understood what you were going through and it was beyond comforting to have them around. Bobby, John’s right hand, set you up in the home next to his and Ellen’s. You didn't mind, Bobby and Ellen practically raised you and the boys. Especially because Alpha John began spending more time away from the Lodge. Bobby stepped up and handled most of the Pack business on John’s behalf. He also spent more time with Dean, mentoring him.
***************
At 16, you and Sam became more than best friends, you became lovers. It started out as a serious discussion, you both confessing your fears of not pleasing your future alphas. Sam was lucky, he knew he would be Dean’s mate; he had grown up with him, was already comfortable with him. You didn't have that luxury, you would probably be mated to a stranger. Yet, every omega’s fear is the same: would you be able to please your alpha? You and Sam had this discussion many times, every omega adolescent does. The other big topic, how painful will your first heat be? The first was always the worst, usually because you’re not mated when it happens. Heats are easier to bare with an alpha there to help, or when you’re mated. The discussion turned to preparation for the future. Sam came up with the idea that you could help each other, through heats and with preparing for alphas.
“Sam, that’s not gonna work. I’m female, Dean isn’t. How would I possibly be able to help you know what he wants from his omega?” Sam argued,
“You’re our sister. I’m sure you’ve noticed things about Dean that I haven’t. Plus, pleasure is pleasure. If I can please you, I’ll feel more confident when I’m with him. I think this will work, please!” He flashed you his puppy dog eyes. You stood no chance,
“Fine…I guess you’re right. Plus…it could be fun!”
It really was a great situation. There would be no worry about pregnancy or mating, and you would be able to comfort each other, taking as much time as you would need. Sam was an amazingly patient lover. He pulled you into a hug while caressing your back. You easily leaned in and scented him. His scent had always helped you calm down, the benefit of being raised together and being best friends.
Clothes came off next, as you both crawled into your bed. Sam laid you down and began to kiss you. It was the first time either of you had kissed this deeply, it was messy and hesitant. After a few moments, your mouths opened and tongues began to dance. The kissing got better, you both found a rhythm. Sam began kissing down your body as you moaned.
“Sam…this is…amazing.”
“You are so beautiful. Can I…touch you?”
“That’s what we agreed on isn't it? Please…don't stop.” You finished with another moan earning a growl from Sam. It vibrated through your body bringing more whimpers. He moved down to your thighs and began licking and kissing your folds. You began making sounds you didn't recognize as your own, which were followed by Sam’s noises. He stopped to suck on his fingers before pushing them in, one at a time. Your body bucked. The sensations were all so new, slightly uncomfortable but exciting. He worked his two fingers a few more times before pulling them out and moving back up your body. He inhaled at your neck then asked,
“You ready Babe?”
“I think so…yes!” He slowly pushed into you, giving you time to adjust to his size. Sam was a well endowed for an omega, even without a knot, he was larger than some alphas. You whined a little once you needed him to move and he understood. He started out slow and gentle, but by the time you both finished he was slamming into you enough to move you on the bed. He pulled out and rolled you both over. He pulled you in close to snuggle and scent each other. Another benefit to both being omegas, you both needed to cuddle after sex.
It hadn't taken much longer to work through all the other combinations between you and Sam. You both spent a lot of time experimenting. Sam learned a lot from your servicing of his cock, what it felt like to gag and deep throat, or even face fuck an omega. He also learned what he liked from a blow job and how to perfect hitting a males’ prostate with fingers. You both enjoyed each others’ sexual company; it was incorporated into your relationship easily and naturally. It soon felt like you really were his sister and future mate.
***************
Sam and you had spent last night together, it was fun and comforting, just what you both needed. He has been even more needy of and aggressive toward you since you turned 18. You both knew your heats could come at any moment, signaling your official presentation and availability for mating. Once Sam’s heat hit he would be expected to mate with Dean and become Pack Omega like his mom before him. He won't be able to spend as much time with you then as he can now.
Once your heat came, you would be expected to mate with an alpha. Since you had no official family, it would be mostly your choosing. Sam worried about you and your future just as much as you did. All of these thoughts and concerns led you both to spending as much time together as possible.
Dean was out on Pack business, and wouldn't be home until later that day. His trips away from the territory have been shortened to less than 2 days at a time. This is to ensure that if Sam goes into heat, Dean can reach him quickly. You usually didn't spend time in Sam’s bed with him because it is also Dean’s bed. They have been sharing since Dean became Pack Alpha, roughly two years ago. The thought of getting caught in Alpha’s bed was terrifying to you, but Sam thought you were paranoid, he also found it funny. He knew Dean would never hurt you, you were too much a sister to them. But you knew how possessive alphas could be, especially Dean, and never wanted to be on the receiving end of his anger.
Sam was already awake and reading in bed, letting you sleep in and cuddle him when Dean came into the room. From the angle you were positioned Dean couldn't see who Sam was sleeping with. Dean looked shocked, then pissed,
“Sam, you wanna explain why there’s a stranger in my bed? With my future mate?” Sam looked shocked to see Dean, could smell the anger coming off of him, but then urged him to stay quiet, putting his book down and motioning with his hands, he responded with a whisper,
“Dean, it’s not what you think. Nothing’s gonna happen here.”
“What? Like carrying someone else’s pups?!” Sam looks ready to laugh at how angry Dean is getting. “Is this amusing to you?” Dean looks genuinely hurt, yet the anger scent persisted. Sam notices you twitch at the scent of anger in the room, he rubs your back as you relax again. Sam feels bad,
“Dean, you mean everything to me. But, she does too. We need each other, especially now…Since you became Pack Alpha, I’ve had to rely on her, and she’s relied on me a lot longer. Please…don’t make me stop this.” Dean looks confused, he moves over to Sam’s side of the bed and looks. His face shows his realization as he sees you asleep, curled into Sam. Dean moves back and sits down next to Sam and sighs deeply as he runs his hand down his face. His scent changes immediately to relief and comfort,
“You had me worried Sammy. But…I get it. I’m glad, really, that you have each other. I would never split you two up. I know you would never forgive me, plus I don't think I would forgive myself…So how long has this been going on?”
“About 2 years, just before you became Alpha.”
“Wow. I thought all this time she was acting this way because she…liked me.” Dean laughs, but it is an awkward, slightly hurt laugh.
“What do you mean?” Dean grabs Sam’s free hand, stroking it with his fingers while he thinks,
“Ever since I became Alpha she’s been…different, I don’t know…awkward maybe, around me. Always making sure to use my title and bow her head. It’s weird, she was raised as my sister, I never expected her to treat me differently once I took over…”
“Dean, she’s just being respectful. Everyone in the Pack treats you that way.”
“You don’t, neither do Bobby or Ellen. I just…I don't like it when she’s like that. It makes me feel like her Alpha, not her brother. I miss her…the way she used to act around me.”
“Do you treat her differently since you took over? Like how you have to treat everyone else in the Pack?”
“What do you mean? No, I don't treat her differently.”
“Dean, you have a lot of responsibility as Pack Alpha. You rarely let your guard down, maybe the only time is in this room. I see how you behave around the others, maybe she does too. She knows it's not the only part of who you are, but if you only treat her that way, then that’s who she’ll respond to.”
“Hmm. I guess…I’ll have to make the effort of acting more brotherly around her.”
“Do you only miss her because she’s our sister?” Sam has a devilish smirk on his face.
“Yes, but…for a while now…I’ve thought she is the prettiest female in the Pack.” Sam can’t help but notice the way Dean is looking at you. He has this dreamy look on his face. “You know, I haven't seen her asleep in years, she looks even more beautiful, so peaceful. I really miss spending time with her…” Sam notices the slight scent of desire from Dean and nods,
“I don't know how I’m gonna survive without her.”
“What do you mean? I just said I’m not gonna make you two split up.”
“I know, I don’t mean that Dean. She is going to mate with some alpha, from who knows where? She won’t be living near us anymore. I’ll be lucky to see her once or twice a year, depending on how far away she moves.”
“Shit, I hadn’t thought of that. I guess I was so used to having her around…She doesn't want any of the unmated alphas from our Pack?”
“Would you? No offense to them, but they aren't really the right fit for her. I mean Kevin and Ash, are nice, but they’re a bit too young. Rufus and Jim are too old. Charlie or Jo would be great, but she doesn't really want a female. And Garth, well, is Garth…Oh! What about Castiel?” Dean thinks about his friend and village apothecary/healer for a minute. He doesn't really know what to say about Castiel. Dean learned his story in confidentiality and would never want to jeopardize his friendship or honor by revealing those facts. He thinks of a way to cover,
“I don’t think they would be a good match.”
“I don’t know. He’s smart and caring. He seems like good alpha material. He’s not too bad on the eyes either…and his scent is pretty intoxicating…” Dean responds playfully,
“Anything else you’d like to admit about my best friend?” Sam is caught off guard as he stares off dreamily,
“No, I think I covered it…joking aside, if Castiel isn’t an option then she’ll have to go to a stranger, which is even more terrifying.” Dean nods, he understands how scary this must be for both you and Sam. He can smell Sam’s distress about the whole situation, and watches as you shift uncomfortably at the scent. Sam immediately runs a hand through your hair and focuses on changing his scent. You nuzzle in closer and drift off. Dean realizes that he doesn't want to lose you, but he doesn't want to admit his feelings to Sam. He thinks he may love you, in more than a sisterly way, but he figures there is no point, Sam is already destined to be his mate, there is no reason to hurt Sam’s feelings or acknowledge his own when he can never really have you for himself.
“I could find her an alpha, one that’s good and respectable, and who’ll treat her right…I’ll use my Pack connections. I’ll make sure he takes care of her.” Sam is shocked by this statement, he thought Dean would fight for you, try to keep you around, at least for Sam’s sake. Sam sadly realizes that politics play more of a role in Dean’s life than they do for omegas. He nods his head,
“Thanks, Dean. Can you make sure he lives close too?”
“I’ll do what I can…She deserves the best. Okay, I really came in to talk to you about the Moon Run. We only have a few days to plan. Was there anything special that you wanted to do this month?” The Moon Run is a traditional Pack event which happens on every full moon. The Pack runs together through their territory, led by both Pack Alpha and Omega. Sam thinks for a few minutes,
“No, I think we should keep this one simple. I’m not sure when my heat will kick in, and if it should happen this week we don’t want to cancel major plans.”
“Good idea.” Dean blushes a little when he asks his next question while rubbing the back of his neck, “Speaking of heats, any plans on who’s helping her…with her heat?” Sam is a little shocked,
“We had planned on helping each other. Not that I need her to unless you’re not around…” Dean just nods silently. Then comments with a frown,
“It won’t be as easy for her without an alpha.” Sam knows Dean isn’t going to like what he says next, he speaks slowly,
“I know, but we’ve discussed it. We’re confident she’ll be okay…Plus she doesn't know if she’ll be comfortable with anyone else…” Dean looks hurt. Clearly he hoped you would think of him to help you through that time. If not himself, he figured you would ask Charlie since you’ve always had a good relationship. Dean just wants his omegas to be safe and cared for, whether he helps or not. It’s a Pack Alphas’ duty to help omegas through their first heat should they ask. In some Packs, it’s considered an honor if the Alpha lays with the omega, but the Winchester Pack doesn't hold this as tradition or a mandate in any way. He figures maybe he should take the first step,
“Well, then…I’ll do my duty as Pack Alpha and offer myself…to both of you.”
“That’s nice Dean, but it’s kind of a given that you’re helping me, and…she’s asleep, I don’t think I should offer you to her, it really should come from you directly.”
“Wake her up! No time like the present.” Dean stands up and walks back toward the door, giving you and Sam some privacy. Sam leans over and gently runs his hand through your hair.
“Babe, you need to wake up. I need to talk to you.”
“Sammy…wha?…” You yawn and sit up to stretch your arms out. The covers fall off your chest and you sit there exposed. Dean catches himself staring at your bare body but he recovers quickly, looking everywhere else, he clears his throat. You turn and see him standing there and quickly hide under the covers. Your impending panic attack is delayed by Sam rubbing his hand over your back since you have buried yourself under him to the best of your ability.
“Dean wanted to ask you something, Babe.” You are shaking with terror, you can’t bare to look at him, you know protocol is to greet the Alpha, you address him from the shelter of Sam’s side and under the covers,
“G…good morning…Alpha.”
“Good morning. I hope you slept well?” Dean’s cheesy smile is lost on you, as you shake even harder. Sam gives Dean a look that has been called his bitch face on occasion. “Yes, well…I just wanted to officially offer my…services…as Pack Alpha…to you…if you need me…for your heat, that is…if you need me…if you don't already have someone I mean…” Dean scolds himself for sounding so awkward and confusing. He knows he isn't being very Alpha like, but the two people he dreams about are both naked in his bed in front of him, he feels like he should be given some credit for even still thinking at this point.
“Th…thank you Alpha…that is very kind.” Dean nods his head and looks to Sam, who is still rubbing your back calmly. Dean is trying not to get angry with you not looking at him while he is addressing you. His rational side knows you must be embarrassed, but he is offering himself up to you on a platter and you can’t even look at him! His frustration scent must be filling the room because Sam quickly speaks up,
“Thanks, Dean. I’ll see you later today right?” Dean looks relieved that Sam is throwing him out,
“Of course, Sammy…have fun you two…” Dean exits as fast as he can. Afterward, he beats himself up about how stupid he sounded. He was doing fine until you woke up. Plus now, he’s worried he gave Sam the wrong impression about his feelings towards you. He seeks out Bobby to talk about legal matters concerning the Pack and investigating possible mates for you.
After you hear Dean leave you let out all the tears you were holding back. Sam is concerned,
“Babe, what’s wrong? Why are you crying?”
“He’s gonna kill me! I’ve been sleeping with his mate, his brother, oh my god, he’s gonna kill me.” This is repeated more times than you can count. Sam calmly rubs your back, pushing his calming scent as much as possible. It helps a lot.
“He isn't gonna kill you. He loves you, like a sister. Don’t worry.”
“Sam, he’s an alpha, not just any alpha, THE Alpha. Capital A Alpha! He has every right to kill me, he could even make it look like an accident, oh shit…shit…shit…I gotta go!” Sam squeezes you even harder.
“You’re not going anywhere until you calm down. Seriously, Dean is okay with this, with us. He is happy that we have each other for comfort. He knows that he hasn't been around lately for either of us. At least, we’re not out being reckless with betas or alphas who could cause damage to us and our ‘honor.’ It’s not that big of a deal, really.”
“I don’t know. I would never hurt him, if that means we need to split up, I get it. I just…don’t want him to hate me…I…wouldn’t be able to live with myself if he did…”
“What are you saying, Babe? Do you love Dean?”
“Well, yeah, he’s my brother, like you, but…I’ve never felt the same way about anyone else besides you. The way you describe your feelings for him…I…have the same feelings for him too…I miss spending time with him, I miss his laughter, his smile, I miss everything about him…Please don't be mad with me Sam! I can’t help it, I think I love him.” Sam is shocked. Both of the people that he cares about the most have been secretly in love with each other and don’t know it.
“Oh, Babe, I’m not mad at you, how could I be? I know how easy it is to love him. I just wish there was something I could do…to help you.”
“What do you mean? I can’t ever be with him. If I did, it would ruin my chances with another alpha…That’s why he can’t help with my heat…I couldn't bear it, being with him in that way, but never being able to keep or truly love him…” Sam understands as he’s hit with another layer of frustration. Knowing you are in love with someone that you can never have. He feels much the same way about you, and it sounds like Dean may feel the same way too. Sam thinks there must be some solution for all three of you to be happy. He stops thinking this way, knowing you’ll pick up on his frustration, and he would rather calm you down right now. He slides down into the bed and pulls you closer and squeezes you in his arms. He doesn't let go even after you fall into a fitful sleep. He continues to hold and caress you, finally, you quiet down in your dreams.
