Okay don't mind me, I've just been reading too much about various sorts of mythology stuff and... old myths genuinely have a lot more weird pregnancy things than you'd expect (I still find the fact that Odin's eight-legged horse in Norse mytholohy is the son of Loki - whom Loki was pregnant wirh anf gave birth to, mind - way too funny, although that's completely beside the point), so... this isn't inspired directly by a specific myth, but reading random mythology stuff is kinda what put this into my mind
Anyway, I've been thinking of a boy who somehow manages to royally piss off a fertility god. Perhaps he defiles their shrine, or steal some sacred item or mess with their priest - or maybe him just refuses to do something the god wants him to do. And because gods are so well-known for never being spiteful and always giving proportionate and reasonable punishments (extreme sarcasm), the god curses the boy to become pregnant, but unable to give birth unless some extremely specific conditions are met. Maybe he can only give birth at one specific location, or has to eat some specific hard-to-aquire thing to induce labor, or it's one of those seemingly impossible and contradictory "neither at sea nor on land, neither at day nor at night, neither alone nor with other people" kind of conditions (i pulled that specific one out of my ass but you can find similar kind of contradictory and stupidly specific shit in mythology sometimes, you get my point), or some combination of the above, or some other stupidly specific and unintuitive condition, idk.
And the boy doesn't know the condition, of course. The first nine months he simply waits for the pregnancy to run its course, but as the months stretch on past the ninth, past the tenth, with no sign of the pregnancy coming to an end, he realizes he's not getting off the hook that easily. By then, of course, he's so heavily pregnant that everything is difficult - he can't walk very far at once at all, he needs ridiculous amounts of fabric to have clothes that fit, the baby - or babies, rather; he can't tell but he thinks he must have two or three in there - are restless and kick and writhe so he hardly has a moment's peace from them...
So he becomes searching for some solution, some way to birth the babies. First whatever conventional ways there are to induce labor. None of them do anything. He prays and makes sacrifices to the god, groveling and apologizing and begging for relief. No response. Then, he begins to seek out wise people, priests and oracles and shamans, first close by, then traveling further and further away to find someone who could tell him what to do.
It takes years, years of incredibly difficult travel, of weird looks from others and humiliation and yet often having to rely on the aid of other people to get to wherever he's going this time, because really he's in no state to travel except he doesn't have a choice. After the initial nine months, the babies do seem to grow slower than before that, but they do still grow little by little, making the burden quite literally heavier to bear, and they are restless in his womb, as though they too would know it is well past their time to be born already.
But finally, after years of searching, years of torment, the boy finds out the condition, and figures out a way to fulfill it. Once that is done, though, there's still the incredibly long and painful process of labor and giving birth to the babies, now much larger than his body ever was designed to give birth to...
I loooove perpetual pregnancies like this!!! It could even be similar to the Greek story abt Leto, so he’s in labor as he tries to figure out how to break his curse. Imagine him having to suffer through contractions, feeling his baby’s head sooo painfully low in his hips as he tries to push but the curse prevents it from coming out all while he’s in search of a way to give birth.
After years and years of searching, his babies become massive. Even with the slowed growth, they’d be the size of 2-3 year olds by the time he finally manages to fill the conditions to progress his labor. Maybe as he’s finally giving birth to his first baby, the god that cursed him decides to come down, just to torment him one last time before his punishment is over. There’s nothing the boy can do to get way from the god, belly pinning him to the ground with the weight of his writhing babies, unable to escape the wrathful god. Each time his baby comes to a crown, the god pushes it back in, making his scream is sob in agony, begging to be let go as it makes his tummy twist and writhe. He tries to kick and push the god away, but he’s too weak after carrying such a burden with him for so many years, completely helpless in the hands of his tormentor.
It goes on for days, weeks even, the god switching between pushing his babies back into his belly, then and painfully squeezing the swell to watch him thrash. Once they’re sure he’s learned his lesson, they let the last baby slip out between his trembling legs, leaving him exhausted, alone, surrounded by half a dozen massive babies as he’s finally allowed to pass out
