A New Sort of Grace by DarkCaustic

Summary: Maybe angels are rather genderless and don’t go through heat and rut, but now Cas is human is he is clearly beta.

Because that is the unmistakable musk of beta in heat.

Comments: 10/10 Cas is a beta in this one, but he goes into heat. Cas goes into heat and Dean has to be a gentlemen and help him through it. Extremely unbelievably hot, Dean’s inner monologue and the amount of restraint he has to practice. Ugh. I’m drooling and squirming.

If you're still taking prompts, could you maybe do Sam-centric Wincestiel with "I'm pregnant" please? :) (No worries if this doesn't appeal, though! I hope you're having a good day.)

Finally, a reason to make myself write more in this verse! Wincestiel with abo dynamics and smut.

“Sam, I think the condom ripped,” Castiel paused in hismovements above Sam.

“What?” Sam snapped, “Why did you stop?”

“The condom,” the angel moaned when Sam clenched around him.

“Why’d you guys stop? It was just getting good,” Dean walkedback into their bedroom, munching loudly on chips. He settled into the chairnext to the bed.

“Keep going, damn it. Or I’ll flip us over and do it myself!”Sam growled, “And you! Quit eating chips like you’re watching football and comekiss me!”

Cas didn’t want to argue with an omega in heat. Dean droppedhis chip bag.

Weeks later, Sam missed his next heat despite the odds beingstacked against him (over 30, questionable health, and a male omega, the leastfertile). He was regularly being bred by a beta and an alpha (after much angstand longing, Dean finally joined them in more than being a spectator) but Samwas pretty sure it was his last heat that got him knocked up since they alwaysused condoms and that time was the only mishap.

Dean. Oh god. How was he going to tell Dean when the thing betweenthe three of them was brand new?

That night in bed, when things were getting hot and heavyagain, Dean was keeping up a steady stream of ridiculous dirty talk whilefingering both Sam and Castiel at the same time.

“Gonna fuck you, Cas. Gonna breed you and pull out andfinish in Sammy so you’re both full of my come like good little bitches.”

Sam rolled his eyes but Cas groaned and clutched at Sam,pressing kisses to Sam’s throat.

“You like that? You want my knot, you little comesluts?” Samdidn’t know how Dean ever got laid if he talked like that to anyone he hookedup with.  

“Yeah, I guess we don’t need condoms,” Sam saidconversationally. “I’m pregnant.”

“Don’t get me wrong, Sam. I am beyond thrilled and honored to have fathered a child with you. But I don’t thinkyou should’ve told Dean like that,” Cas said, petting Sam’s hair as the youngerWinchester went down on him. Dean was holed up in his room, freaking out oreating chips again. Stress eating was one of his many coping mechanisms.

Sam pulled off of Cas’s cock with a pop. “He’ll get over it when I let him breed me. As long as hedoesn’t start with the stupid Casa Erotica porno speech again.”

“I liked it.” Cas blushed.

“I know you did. Congrats, papa. You want a little reward?For being such a good little beta and knocking your mate up?”

Cas bit his lip and nodded. Sam gave him a wicked grin andresumed sucking his mate’s cock.

I search on Google for stuff related to the star Beta Cassiopeiae by using the search term "beta cas". Guess what comes up as a result from ao3.

Hmm how about alpha!Dean is mated with beta!Cas. And everyone tried to convince them to not do that, because as much as one alpha male with beta female works, it don't with alpha male and beta male, the chance of Cas be able to get pregnant is almost none and everyone knows Dean want kids. So they are happily mated for five years, which they spend hoping Cas would somehow get pregnant but it never happened. +

Cas tried everything. All type of medical and herbal help. Tried so many different sex positions (Cas was so flexible by now that they could do almost everything). Nothing worked. So Cas decided to give up, Dean told him so many times that was okay, he loved Cas more than anything and knew that they may not have kids. So it was unexpectable that after two weeks of throwing up every morning, he took a pregnancy test (after his friend Nora point out that it wasn’t a stomach ache) +

the result was positive, something that his doctor confirmed. He cried of happiness and he went home straight away to tell Dean the amazing news. Dean could deny as much as he wanted, but he cried when Cas told him he was gonna to be a dad. :)

Oh yes please! ♥♥♥

Can you please tell us more about Alpha Dean and Beta Cas??Btw, I love your take on it :)

(All I can think of at the moment is mpreg, anon. I hope that’s okay.)

Castiel throws the the pregnancy test in the trash can. 

It’s negative again. 

That’s the third one he’s taken. They’ve been trying for what feels like months and each time it’s come back negative. 

Dean leans against the door, watching Castiel carefully. He holds his arms out to pull Castiel into a hug, grateful when Castiel accepts it. It would be so easy for Castiel to push him away. It’s what happens to a lot of couples like them.

Things that are so easy for Omegas, aren’t easy for them.

Betas can get pregnant but it’s harder work. Castiel is taking pills. They make him wet, make his scent sweeter, mimicking the kind of scent he’d have if he was actually an Omega. Dean knows that Castiel blames himself for the fact that all the tests have been negative. He thinks that it’s his biology that’s working against them.

Dean knows that isn’t true. Castiel is doing everything he can. 

It’s Dean who’s the problem. What kind of Alpha is he? He can’t even get his mate pregnant.
