WARNINGS FOR

- So much SEX

- Knotting

The drive to Bobby's was a long one.

Sioux Falls, South Dakota was a long way from where they had been held. Even then, Dean wasn't entirely sure where they had been for almost a year. It didn't bother him as much as he thought it would. What was done, was done. They were out, safe and together, that was the main thing.

Bobby appeared to be a grumpy old grouch, faded ball cap sitting atop a bearded face. That was, until he'd caught sight of the twins, then he'd melted into a puddle of goo. John seemed amused by the fact, but a little sad.

Turned out, Bobby's wife had died in child birth, along with their baby. That was going on twenty years ago, and the old man had never remarried.

He had welcomed them into his home without hesitation, set them up in their rooms, shared, of course, and left them too it.

His house was situated miles out of town, in an old junk yard, much to Dean's delight. It meant he could use his hands again, be useful in things he actually knew how to do.

His dad and Bobby set them all down after they had settled in, after the other men that rescued them had said their goodbyes.

"Boys, I'm gonna be straight with ya, no pussy footin' around." Dean smirked. He liked Bobby. He was the kinda no bullshit guy that reminded him of his old man. "We got some good news, and some bad news." Dean looked at Cas, and felt a pang of sympathy. They had been wondering about Anna, but he knew Cas was too afraid of the answer to ask.

"While you were inside, more and more of the disappearances became public. They really fucked up big time once, trying to take a dude in broad daylight." His dad rubbed his face, a world weary gesture Dean was all too familiar with. "He got pretty worked up and went feral. Too many people saw him jump too high, and got a close up of his teeth." Dean shivered, because he knew exactly what that meant.

"So the world knows about us now?" Sam asked quietly. The two older men just nodded.

"You bet they do. Once the right people did the right kinda digging, and the, ah, right information, was handed to them," John winked at Bobby, who tugged on his cap, almost self-consciously, "Well, shit went south real fast."

"The people who were funding the facilities, Roman Industries, weren't part of any government organisation. Apparently, the contracts Dick had with the government were top secret; even the higher ups didn't know how he was developing the serum."

Dean nodded, that made sense, because even their secretive government wouldn't have stood for testing on kids.

"Anyway, long story short, they started investigating the facilities, but as soon as Dean rang… I couldn't just let you boys rot in there while homeland security waded through miles of red tape." Dean grinned, yeah, their dad was awesome.

"That brings us to the good news." Bobby smiled, and it was amazing how it lit up his whole face. "The first place they shut down was up in Washington, where your sister was held, with that doctor friend of hers." Cas and Gabriel both yelled out at the same time, their words mangling together in a mash of excitement and happiness.

Dean smiled at his happy mate, but needed to know what had happened. "Dad, where are they?" His dad turned to him, still smiling at the brother's reaction.

"Her and Balthazar are holed up in another safe house. They got tested while they were in there, nothing too bad, apparently, but turns out they're both something called a Beta. They got the gene you boys have, but without the, ah, extra bits." They all laughed at the expression on the older men's faces, but it was a relaxed, happy laugh.

"Can we see them?" Cas asked excitedly, grin almost too wide for his face. Dean felt that last little bit of worry slide right off his shoulders, and he reached under the table for his mate's hand. Cas shot him a cheeky look, one Dean hadn't seen in months, and knew Cas felt exactly the same.

"In a few weeks, we just gotta sort some stuff out first. In the meantime, you boys rest, relax, and let us handle everything." Dean nodded, along with the rest of them, but felt he needed to say his bit, because no matter what had happened, he didn't think he'd ever be able to thank his father for everything he had done for them. He cleared his throat, a blush creeping up his neck when everyone turned to look at him.

"I just wana say, well, I think I speak for everyone when I say, there's no way we can ever thank you enough for what you've both done. You put everything on the line for us, and I – I um, just thank you, thank you so much." Dean had to stop before he sobbed himself into a hole of embarrassment. His dad though, clapped a big hand on his shoulder and pulled him into a tight hug.

"I'd do anything for you boys, I'd go to hell and back to save you. You're a father now, Dean, I expect you understand what I mean." He did, more than his dad would ever realise. "You don't have to thank me, because I would do it again and again, no questions asked." Dean choked up, and didn't even care that everyone could see him. He felt another pair of arms envelop him, and just knew instinctively that it was Sammy.

His whole family was safe, and it was more than he could have ever asked for.

"Sammy!" He turned when he heard Gabriel's voice echo down the stairs from their room. Sam was reading in the study, but his attention was immediately focused on his boyfriend. Gabriel hadn't been feeling well the past few days, and they were worried it was another complication from the drugs that had forced upon him.

Sam stood up, carefully placing the book down for later. He rounded the table and made his way to the stairs.

"SAM!" His eyes widened, his stomach clenched and he bolted up the stairs at Gabriel's scream. No one else was in the house, having gone to town to get baby things for the twins. He would have loved to have seen Bobby's face picking out tiny pink onesies, but he had wanted to stay and take care of Gabriel. Now though, he wished he wasn't so alone. He had no idea what to do if –

He burst through the door and was hit with such an intense smell of honeyed candy and cinnamon that he almost gagged. He inhaled sharply, groaning when the smell went straight to his rapidly smelling cock.

"Sammy, please. You know I don't like to beg." He opened his eyes to a panting, writhing, very naked Gabriel spread out on their bed. It hit him all at once, the smell, the look on his boyfriends face…

Gabriel was in heat.

His first heat for months since he had been drugged and almost died. Sam's heart beat harder in his chest, everything they had talked about flooding to the front of his blood drained brain.

"I can't mate with you Sammy, not until I have another heat."

"But why, Gabriel, I don't understand."

"I won't let you be stuck with me, Sam, not if I'm broken."

"I don't care if you can't give me kids, Gabe, I lo –"

"Sam, don't, please. I – I can't."

Gabriel was in heat, he was fertile, which meant – which meant he could say everything he'd been hiding inside, do everything he'd been dying to do ever since he had walked into that room and smelt Gabriel that very first time.

"Are you gonna fuck me, or do I have to do everything myself?" Gabriel's eyes were feverishly bright with a fiendish little smirk that got Sam's blood racing to all the best places.

Sam almost fell over himself trying to get to the bed, Gabriel laughing the whole time. His boyfriend tugged at the bottom of his shirt, and he took the hint, ripping it off, over his head. The gasp his bare skin elicited from the smaller man sent a shiver down his naked back.

Gabriel's fingers fumbled with Sam's belt, swearing when he couldn't undo it as fast as he wanted to. Sam just snickered, loving the reaction his body had on Gabriel. He took pity on him and helped, undoing the belt, drawing it out and pulling down the zip. He didn't go slow, too excited and scared to be sexy.

When he finally pulled his pants down, with his boxers, Gabriel's out right moan caught him off guard. His eyes snapped to the golden brown rings almost eclipsed by black which were staring at his hard, bobbing cock.

"Oh god, Sam, I need you, like, now." Sam growled, and surged forwards, pinning Gabriel to the bed. Their lips met in a frenzy, tongues and teeth clashing. Sam just couldn't get enough of the sweet scent of Gabriel, pure and his.

"Mine." Sam growled out past teeth too long for a normal human. It didn't surprise him, or stop him. He was Dean's brother, after all.

"Oh fuck, yes Sammy, yours, but please, get in me." Gabriel was scrabbling against Sam's shoulders, trying to push him away. Sam was confused, he didn't – oh.

Gabriel flipped himself over, tucked his knees up and pushed his ass into Sam's lap. They both groaned when Sam's hard cock slipped and slid against Gabriel's leaking hole.

"Can I – Can I try? Are you like, ready?" Sam had no idea what he was doing, and he didn't want to hurt Gabriel. His cock wasn't exactly small, and Gabriel was tiny compared to him.

"Yeah, I stuck a couple of fingers up there before you came in, I'm so ready." Gabriel reached backwards, and grasped his cheeks with both hands. Sam pulled back to watch as Gabriel spread his ass, revealing his little pink hole, leaking and twitching, begging for Sam. He couldn't help himself; he leaned forward and spread his tongue flat over the puckered rim.

Sweet juices flowed onto his tongue as Gabriel cried out, releasing his ass and surging forward to hold the headboard. Sam lapped greedily, burying his face in the meat of Gabriel ass. It was heady, the scent right from the source, and Sam could barely think straight, let alone break away from his oasis.

"Sam, for the love of all things holy, stick your cock, in me." Sam growled and nipped at his boyfriend's backside, amused by his boldness. He lifted from the sweet embrace of Gabriel's flesh, and grabbed the base of his cock. He could feel his knot vibrating just under the surface, begging for release.

"Tell me if it hurts, Gabe, I don't wana hurt you." Sam knew Gabriel would let him know the instant he was uncomfortable. He rubbed the slick lubricant over his cock, groaning at the sensation. He lined up the head of his cock, flush with Gabriel's hole, and took a deep breath.

He pushed in slowly, as slow as he could, anyway, because holy fucking shit, did it feel good. Gabriel's body took him in, gaping wide and flushed around his massive cock, and only shivering when Sam pressed too far, too fast.

By the time he had bottomed out, they were both shaking and panting, sweat slicked bodies pressed together with only Sam holding them up.

"Are you ok?" Sam gasped when Gabriel pulled forward quickly, and slammed back onto his cock.

Well that answers that question.

Sam grabbed Gabriel's hips, and pretty much lost all coherent thought from there. His hips moved as if they had a mind of their own, pistoning in and out of Gabriel's tight opening again and again. His Omega moaned shamelessly, telling him to go faster, harder, deeper.

It was all Sam could do to hold on, but when he felt his knot start to tighten at the base of his cock, what little blood flow was still in his brain managed to remind him that not only was Gabriel in heat, but there was a very good chance that if they knotted, Gabriel would get pregnant.

He forced himself to slow down, much to Gabriel's apparent horror.

"Sam, I will ask you this once." Gabriel was panting, and Sam didn't blame him. "Why the fuck have you stopped? I was almost ready to come." Sam groaned at his frank admission, and snapped his hips forwards once before he stopped himself.

"Do you want this, Gabriel? If I – if I come in you, you'll get pregnant." Gabriel managed to get himself situated so he could look at Sam comfortably.

"I'm ok with that if you are, Sammy." The weird thing was, he was totally ok with having kids with Gabriel. In fact, it was the only thing he could think of that would complete their little family, well, apart from…

"I'm gonna mate you first, alright?" Sam growled when Gabriel whimpered, and he flew forwards, pumping fast and hard into his soon to be mate. He laid as much of his weight over Gabriel's back as he thought the Omega could take, before he mouthed and kissed at the junction between his shoulder and neck. It was as good a place as any for the bite, but he would wait until they were coming before he did it.

It didn't take very long before his knot started to catch against Gabriel's soft opening, and his Omega cried out with every pass. He could feel the tug of his orgasm gathering in his balls, the tingling sensation running up and down his spine.

"Oh my god, Sammy, I'm gonna come –"

Just before it became too much, and even Sam felt the pull, he bit down, breaking the skin of his mates neck.

Gabriel cried out, jerking and screaming as Sam's knot mercilessly pounded against his prostate. He could feel it when his mate started to come, the spasming tightening of his hold around Sam's knot sending him over the edge with a roar. He drove in deep, wanting nothing more than to be buried as far in his mate as possible. He emptied his load over and over, pumping as much as he could into his mate, ensuring their coupling would result in a child.

He was still coming, but Gabriel was practically limp under him, so Sam manoeuvred him so they were spooning. He pulled the blanket up over them, and groaned when Gabriel shifted and another load of come was forced from him. He couldn't stop the contented growl rumbling out of him. Gabriel's answering purr told him everything he needed to know.

"I love you, Sammy, I'm sorry I didn't say it sooner…" Sam kissed the back of his mate's neck, and drew his tongue over their new mating mark. Gabriel shivered.

"I know why you didn't, Gabe, and that just makes me love you more." Gabriel didn't want him mating what he assumed to be a broken man, but it just made his love for him even stronger, that he was willing to put Sam's happiness first. "I love you so much."

"That's good to hear, Sammy, now how about we get some sleep before the next round, huh?"

Sam couldn't agree more.

Turned out the world just wasn't ready for a new dominant species, especially when it was revealed that Dick Roman was one of them. How he had managed to hide it from everyone was a mystery, but once he took off, the flood gates were opened.

All the facilities were shut down, and everyone was released. There were riots and hate crimes, but most people were good at hiding what they were. Dean still didn't trust some nut jobs not to hunt them down and bundle them away for research, so they stayed put. Bobby's was a good place, and even Michael and Adam wanted to stay.

Bobby had Michael and Dean fixing cars, while Cas, Gabriel and Adam looked after the kids and did general house stuff. Gabe complained that it was sexist, but after Dean had him outside in the hot sun fixing cars for a day, he didn't seem to complain all that much again. Cas just laughed. Sam helped John and Bobby with the information network, finding kids like them that were in trouble, helping them in whatever way they could.

No one was really surprised when Gabriel sat down at the table one morning, reeking of spun sugar and candy apples. He and Sam were over joyed, as was everyone else. Lucky they had so many people to look after their ever expanding broods.

The world wasn't ready for them, and Dean could understand their reluctance. It wasn't easy being told your species was obsolete, that it had to move over and make way for a more evolutionarily sound model. Eventually, the humans would die out and they would become the dominant force of the world, but until that time came, they were content to raise their kids, do their jobs and help whoever they could, all in secret.

END.
