They're hunting a tentacle monster when some of its slime gets inside both of their mouths. They kill it, and though they retch to try and rid themselves of the slime, they both seem okay. They go back home and think nothing more of it.

But then next morning when they wake up, Sam and Dean are horrified to discover that in place of their cocks, they each have a large, sensitive tentacle. They're freaking out when the two tentacles start reaching toward each other. Scared, but wanting to understand what's going on, the brothers cautiously inch their way together, satisfying the insistent tugging in their groins.

Once they're in range, the two tentacles suddenly strike, seizing each other and coiling around one another, writhing like two snakes struggling to mate. The sensation of their tentacles sliding together is a pleasure unlike any the Winchesters have ever felt before.

Children will be our salvation
Deanna wasn't thrilled with the idea of having her brother's incest baby in the first place, but lately she's not even sure if the thing she's carrying inside of her is even human. Sam swears everything is fine but the feral way he fucks her and the things he whispers while he thinks she's asleep suggest otherwise.

When Sam Was...
Dean and John are alphas, right? So of course Sam would think he would turn out to be an alpha just like them. He turns out to be (of course) an omega, though.

That's all fine and dandy. Sam's got to deal with the normal omega tropes like heats every now and then, pushy strange alpha men and women getting all handsy with him, and an overprotective father and brother who want to lock him up in the motel room and never let him out.

On top of that, though, Sam gets a period. Maybe it's not a really common thing? Maybe only the most /fertile/ of omegas get one and, lucky Sam, he is.

It makes him even /more/ wanted by alphas and John and Dean even /more/ protective of him.

I just really want Sam freaking out when he finds blood in his pants and maybe Dean freaks out as well until he (or John) figures out what's happened. (Sam can have a vagina or you can make him have an ass-period. I don't have a preference.)

And anyway Dean was having trouble holding himself back just when Sam was in heat. No this? An extremely fertile omega right in the next bed? He can't resist. And mating happens. Then pups.

Bonus if you wanted to squeeze in a little part about Dean or John bringing an embarrassed/moody Sam some pads or tampons and trying to explain to Sam how to use them.
