While I logically agree, I have a story (it's mine mine mine kinda mine) that ended up being exactly that because of two peoples' feedback and it's (for me) the happiest story ever. I reread it all of the time.

I know what story this is, and I reread it all the time, too. Just last week, as a matter of fact.

and I reread it all the time, too.

Given that you and I were the target audience? It's nice that we reread it a LOT.

I wonder (kinda suddenly) what a childbearing ass looks like. No, that's not an invitation to link me to a picture of a pregnant donkey (or Jenny McCarthy). I'm just wondering what, in MPREG, are the equivalent of childbearing hips. Or are we ripping it out of the front, or extracting it from his soul?

Eggs come out of the butt, though, right?

Eggs come out of a cloaca, which is the bird's orifice for everything that comes out and goes in the rear parts, so yes, in a sense, eggs come out the butt. I don't think that can be reasonably extrapolated to humans or humanoids, but reason may have nothing to do with an MPREG story.

MPREG always makes me think of that one storyline in the Constantine comics. Eww.

I wasn't thinking about bird eggs. I wanted to know about MPREG eggs. Where do they tend to come out of, in general MPREG terms? Caesarian? Butt birth? Would a guy need a childbearing ass in order to lay one?

For anyone who reads wincest, and happened to read all the way through the horrifically bad Stranger in Love, wtf happened? I began skimming early on due to the weird scenes (a waitress scolds the boys for not ordering coffee, insisting that it's policy that they do so before anything else, and it isn't received by them as freaky and needing to exorcise her or flee) and increasingly-hard-to-parse sentences. After the incredibly long nonsense about mutli-dimensional portals to other universes and "guides" that ends up being resolved with salt-laced varnish, it turned out to be a case of shapeshifters. And the prologue and epilogue confounded me. I just . . . usually when a fic is bad I just dismiss it, but this one is bugging me, lingering. It was like it was written by an ESL dementia patient.

Lo mein: maybe the unfortunate butt-bearing boys have tiny skinny babies that don't impact their (Sam Winchester's) lovely skinny hips.

Most of the mpreg I've read, there's a Caesarian involved. Once there were eggs involved, but the babies did turn out to be ducklings, to everyone's dismay. (Stargate Atlantis lends itself to weird technology doing weird thing.)

What little mpreg I've run into (like, four fics) two were angelic births that were spiritual/metaphysical and didn't involve actual physical birth, even if the end product was physical non-vessel-having. The other two the writers skipped right over the physical act of birth. Sex, then babies.

Well, I figure Supernatural fandom will either go egg, or go grace. How are you gonna know?
