It's been done a thousand times, but this is my short take on Dean's POV on the Sam!mpreg situation.
Title: (Untitled Sam!mpreg ficlet)
Rating: PG13
The thing about having a kid with Sam, and it was actually having a kid; pregnant for 9 months and all, is that Dean doesn’t hate it. While Dean doesn’t exactly say he loves it, as Sam’s irrational mood swings and cravings drives Dean nuts, Dean can’t say he isn’t glad.
Not just because he loves Sam no matter what and having a child with Sam, being the other parent and all, is a miracle that Dean had not anticipated at all. Although the warlock that set up the spell and the books it was written in probably classified it under a curse.
Their relationship is rocky at the moment, being that the two of them had been cursed into sleeping with each other and Sam ending up pregnant with their love child. Neither Sam nor Dean remembers exactly what happened that night, everything between some indeterminate time in the motel room when they were going about their normal routine to waking up intertwined with each other in one rumbled bed, naked and sweaty and the smell of musk heavy in the morning air, was blurred at the edges and slipping into blank spots.
But Dean doesn’t regret it. Though he regrets that it had happened under outside influence and that they can’t remember what they did, Dean can’t make himself regret that it did happen, just how it had.
Sam’s belly is starting to round out, losing the trim abdomen that was earned from hard work and a lifetime spent training, because of a tiny life growing bigger everyday. An impossible life fighting for its existence.
It’s a miracle and a benediction that Dean never expected to receive.
Because even as he hid and tried to redirect the encompassing depths and direction his love for Sam had grown, while he still irrationally hoped underneath, he had never contemplated that the idea of having a child with Sam was at anytime probable or possible. Even when he indulged in his guilty thoughts of what a future with Sam would be like if they were together romantically; possibilities of future generation Winchesters had always ranged from finding out that one of them had a child neither had known about, usually Dean, to asking a female friend to play surrogate mother, most of the time Rebecca or Sarah. Never had it been thought that one of them could actually carry and give birth to a child.
Their child. Truly theirs, with no one else in the making. Just Sam and Dean’s.
But now it’s happening there is a burst of white hot emotion scalding through Dean, nerve tingling and thrilling.
Every morning that Sam wakes up to run to the bathroom from morning sickness. Every midnight awakening to see Sam wandering around with food. Every stop at a grocery store to placate Sam’s cravings.
Its Dean’s every wish and hopes come true. This is their family - Sam and Dean’s. It means everything.
It means that Sam will never leave Dean again. Because Sam can’t have sex without becoming attached. Because now there is a third person to consider. Because the child will be an external manifestation of Sam and Dean’s unity. Because even if Sam could leave Dean, Sam could never leave their child, his younger brother’s morals wouldn’t allow it. And Sam couldn’t just leave and take the kid with him, because of the same, because Sam wouldn’t be able to deny Dean the right to raise their child.
Not that Sam was going to be leaving Dean again, but this is a guarantee that it will never happen. Not ever. And Dean’s eyes glow when he stares at the rounding figure of his younger brother in the morning light, Sam wincing as he stands, propping one hand on the small of his waist to relieve some of the weight from his spine. Dean walks over behind Sam and slides his arms around Sam’s midriff, letting open palms spread out on the expanding bump.
“Our baby.” Dean murmurs, breath brushing hot over the back of Sam’s neck.
Sam tries to suppress the shiver it brings, unsuccessfully. Dean knows that Sam’s fighting it. Their attraction, the inevitability that the event they don’t remember will happen again, this time under their own prerogative. Dean doesn’t press a kiss to Sam’s skin, he wants to but he doesn’t, not yet. Soon, everything he’s ever wanted to do with Sam will be within his right; he just has to wait. He’s been waiting on Sam forever, he knows how to play his cards right.
