Disclaimer: I do not own Supernatural or the characters but I have managed to make them into something they hunt but in a good way.

Warning: This is based in an alternate universe where the boys are shapeshifter twins that were adopted by John and Mary after their real parents, close friends of the hunters who were killed by Gordon. They are later adopted by Bobby after the Winchesters are killed on a hunt. He does know they are shifters and has raised them as Hunters, like their adopted parents had been doing while teaching them to be good shifters and how to hide what they are from others.

No, the other hunters don't know they are shifters and they are good at acting human but are fully shapeshifters not human genetically but raised to behave as human by their parents. No, there will be no Lucifer, Michael, or vessel, or leviathan plots in this storyline just the boys hunting as Hunters and shifters.

Yes, there will be Wincest but I will keep it brief and romantic as possible. This isn't that kind of story.

Plot: Sam is feeling different and they check it out. Boy, are they in for a surprise!

Sam felt funny, not ha ha funny but weirdly funny. So he snuck out of their now shared bedroom and slipped into the study. He pulled their parent's journal from its hiding place. He sat in the window seat and read through it, seeing if there was anything to explain the feeling. Maybe the bonding had an after effect or something.

Dean joined him, wrapping legs along his own and hands around his waist, kissing his cheek and leaning in to read it with him.

They both gasped in surprise, eyes wide and reread it, then reread it again. Both shook their heads in disbelief and looked through it to see if there was another explanation.

There wasn't.

Ellen and Bobby came in. They saw their faces and the book in their hands, looking concerned.

"What is it? What's wrong?" Bobby asked. The boys were both freaked out.

"You won't believe this." Sam said softly, still in shock. Dean held him tighter, hand caressing Sam's stomach.

"Try us. We've been through that book a million times, nothing will surprise us about it or you, trust me." Ellen reassured them and they broke out in smiles now, happy as clams but surprised too.

"We're pregnant. Sam's pregnant." Dean said softly, kissing Sam's cheek again, and stroking his stomach lovingly, "My child. Our baby." Sam nodded happily and leaned back against him, still absorbing the knowledge.

"But how? You're both men. Sure, shifters reproduce but not until after…" her thought trailed off as she remember the passage and motioned for them to hand her the journal.

"Look at the marked pages." Dean prompted and both Bobby and Ellen read them. Sure enough, it was right there. 'Once truly bonded, even two male shifters can reproduce and have children with each other. This is rare, since most shapeshifters choose female mates but it has been known to happen in such rare cases. The body of the male shifter will shift to accommodate both the pregnancy itself and the labor resulting. Pregnancies follow the same as humans but the child will be like the parents, shifter from birth, even when a shifter mates with a human. All offspring will be shifter in nature.'

Then Bobby pointed out another passage and chuckled, 'After a shifter has bonded, there is a limited time to stop the possibility of pregnancy. The period for this is up to a month after but no more. After a month, the shifter's body will reject any attempt to do so and will heal such attempts to thwart the reproduction cycle.'

"That means if you want to make it so this don't happen again, you need to have that vasectomy surgery before a month is up or you will be having lots of little shifter babies in the future. Congrats, boys, you're going to be parents after all." Bobby said smiling and chuckled at their pleased expressions.

"Can we do a test anyway, to be sure?" Sam asked, he had to be sure. Ellen nodded and went to buy some. Half an hour later, and four tests in, they had confirmed it.

Sam was indeed pregnant.

"Do you think I should get the…well, fixed?" Dean asked and Sam sighed, considering it. Then nodded, Dean nodded sadly too.

"We can't keep having babies, Dean." Sam said, kissing him gently, "One shifter pregnancy is enough, at least for us, don't you think?"

Dean nodded and smiled, "Yeah, it is. You're right, Sammy." He looked at Bobby now, "We should get started on that soon. Sam's right. This was unplanned but damn we don't need any more shifters in this world, there are enough of us as it is."

"You are different than most shifters, boy. You don't shed, you reabsorb the change and become yourselves afterwards. No other shifters do that. You also are faster, stronger, and heal faster than them too. You are Alphas, both of you." Now Bobby was worried, "That means other shifters will be after you two now, even willing to resort to …" He left the sentence that way, unable to finish it. That ending scaring him.

The others could resort to rape even to achieve their means, to reproduce more powerful shifters from his sons' powerful DNA.

"I'll kill any who try." Dean swore, pulling Sam to him more, suddenly afraid for him. His Sammy, they didn't get to hurt his Sam that way or any other way. He'd kill anyone who tried.

"Me too." Sam swore and growled a little in anger. No one got Dean that way, no one, not rape at least. Sex, yes, but rape? Hell no. No one definitely got to have his children but Sam, that was out!

"So fixed, really soon, both of us?" Dean asked, shifters could smell a fixed male of their species, the book said so. He was going to make damn sure that's just what they smelled and left them the fuck alone. It was the only way to keep them safe.

"Yes, next week if possible." Sam said with resolve. He would keep them from hurting either him or Dean. This would do that.

"I'll call the doctor right now. I'm sure I can get it sooner." Bobby reassured them and set up an appointment for the next day with their family doctor, who knew they were shifters and kept the secret, being the son of a hunter himself. He also agreed to be their baby and pregnancy doctor, too. Sam would need him eventually for that.

The boys now headed upstairs and kissed their way to their room, undressing as they went. They made love and rejoiced at the pregnancy, and Dean told Sam how much this meant to him, to them. Tomorrow both would be too sore to make love so they decided to spend the day doing just that off and on that entire day to make up for the loss of ability to do so in the days to come.

They went in the next day had the surgery, it didn't take long but they were sore afterward. Doctor Richards also did a prenatal visit with Sam, and gave him some prenatal vitamin to take.

It took a week to fully recuperate from the surgery but one day for the pain to fade. Their shifter healing doing most of the work.

They would be fine now. The other shifters would smell they were fixed and leave them alone, unfortunately, their child or children would not be so lucky.

Once their children were born, eventually they would be fair game and the shifters would be coming after them, too. They would just have to make sure the other shifters didn't succeed. They would kill them if they tried. No one got to hurt their family, human or otherwise.

No one.

Sam sat on the hood of the Impala and watched the sun rise over the red rocks of the Grand Canyon, smiling softly. Dean marveled at how the multi-colored light highlighted his mate's cheek bones and face along with the rest of him, turning his brown hair reddish then golden with its light. He reflected how perfect Sam was and how much he loved him.

He made a decision.

"Sammy?" Dean said coming to stand in front of him and pushing his knees apart, pulling Sam closer to him, his green eyes mapping his mate's face, memorizing him now, so beautiful, so his now.

"Yes?" Sam said smiling into his mate's face and touching his face gently, long finger stroking that handsome face, his mate's face.

"I have to tell you something and it means a lot to me, so let me finish before responding, okay?" Dean pleaded, he wanted to get this out before he got distracted.

"Okay, I'll listen." Sam reassured him and waited for him to speak. This was important to Dean, so he would listen.

"I don't want to be brothers anymore, well, I know we are but I don't mean like that. I mean I don't feel brotherly, I feel like your husband, your lover, your mate, but not your brother. I don't want any more women or men. I don't want you with anyone else either." Dean leaned in and kissed him gently, finishing with, "I just want you, Sam, just you. No one else for us ever again. Be my husband, not my brother, please?" he felt desire hit him for the golden man in his arms, the man he now found himself needing and loving more than anyone else, not wanting anyone but each other now. "I'm yours, Sammy, completely and entirely yours. You are my only one, I love you, Sammy. So in love with you. Our bond is all that matters now."

"Not brothers then. I don't want anyone else either; I haven't wanted anyone else for a while now. Not since after I found out I was pregnant. I want us to be family, but not like we were. More like we are now." Sam leaned into Dean's shoulder now, "Wish I could marry you, Dean. As shifters, yeah, we can, but , as brothers, no."

"Maybe Pastor Jim would do it for us? He knows about our real natures and he's our friend. We can ask." Dean suggested and Sam brightened, liking the idea instantly.

"Marry me. Dean?" Sam asked and Dean smiled tenderly.

"Yes, Sam, I'll marry you." Dean responded kissing him afterward.

They made love on the hood of the Impala with the sunset illuminating their bodies and their eyes, which glowed with power as they did so. They headed to a motel, checked in, then made love some more, resting in between but taking two days to emerge from the room, happily sated and belonging to each other.

Bobby and Ellen were surprised by the Wedding idea but called Jim anyway, who agreed to do it, with no paper though, marriages like this weren't sanctioned with paper.

Which is how they ended up in the church in tuxes and surrounded by friends and loved ones, doing just that, getting married.

They said their vows and smiled happily, so happy they both glowed now a little. They exchanged gold bands, small ones, and that was it. They were husbands and they were joined forever. They didn't need a paper to tell them this, it was just a piece of paper anyway, it could be burned or destroyed somehow, paper could, but their love wasn't that way. It would last forever and nothing could burn it or destroy it.

They lay in their room later and cuddled, sex done and sleep approaching.

"Husband. I like that word." Dean said, kissing Sam softly, loving knowing he was the husband in question.

"Me, too." Sam said happily returning the kiss, loving knowing that Dean was the husband in the equation as well.

"Still hunting, but not as brothers? Others can think that, for the safety of our true secret, as shifters we can't risk them finding out. Yet we won't be." Dean pointed this out and Sam agreed it was best kept as their secret, right up there with the truth of what they were. "Not ashamed of us, Sammy. I can't risk them coming after us, or the others, it's too dangerous to risk. Not all hunters are like Jim, or Doc, or even Bobby and them. They may try to kill us if they found out. Now with baby, we just can't risk that. For the sake of those we love, we can't tell the truth of what we are. Not brothers, not ever again, not really, but Mates, forever joined, and parents to be." Dean kissed him softly again, hoping Sam didn't think this meant he was ashamed of their relationship. "Not ashamed of us, Sammy."

"I agree, it's too risky, Dean. We have to keep this to ourselves." He leaned in and kissed him softly as well. "Not ashamed of us either."

"I love you, Sammy." Dean said and pulled Sam to him again, spooning back into the front of his body, and smiling contentedly.

"I love you, too, Dean." Sammy said pinning him to his body, laying his head so his face was touching Dean's neck and shoulder, inhaling his scent, loving it.

They fell asleep that way and slept peacefully all night.

They felt content now. More importantly, they felt complete.

Got a hunt coming up and going to work some Mpreg into it as I go.

Please forgive the Wincest, It just wrote itself in, sorry.

I will try to keep it brief as I can in this story, I really will.
