Getting pregnant with a member of Arlong's crew HCs
Warnings: some nsfw parts, pregnancy kink, lactation
Okay, I know it's pretty non-specific. But let's say you work in Arlong Park (you decided it's better to work for stronger side. Or you're just down bad), cooking, cleaning etc. You like to pass the time sneaking away with fishmen, at least those eager to sleep with a filthy human (actually... not a dealbreaker for most of them). And one day, well, the consequences catch you. You're pregnant. You probably don't know who's a father (unless you strictly sticked to one lover).
When you admit your pregnancy, some of the crew members are confused and unsure. Because, well, somehow sleeping with a human and having kids with them are two completely different matters. Some, the more orthodox ones, are outwardly unhappy and propose to get rid of it. But most of the fishmen cheer at the news, especially after Arlong hears about it and announces that it's just a sign of putting humans in their place. Not all must be killed, some may prove themselves by carrying a fishmen's kid.
Even if you don't know yet who the father is, it actually feels like it's a kid of the whole crew. Perhaps you will learn it after birth, when you see the kid's appearance. But that's not certain, if I understand One Piece wiki well, genes of fishmen and merpeople also can skip generations, and sometimes a kid has traits of their far ancestors, like, father looks like a salmon, but gets a shark kid, after their great-great-great-great-grandfather.
Anyway, that doesn't discourage the crew. A potential child isn't a common occurrence in Arlong's Park. Besides, most of them focus on life of piracy and have no stable family waiting for them somewhere. So, well, it's a new kind of entertainment. They will have a new lil fishman, and some of them are actually excited to play fathers and teach the child whatever they know.
I have no idea if they have a doctor on a board, but I suppose at least one of them knows something about medicine. If not, they can just kidnap a human doctor to check on you, just in case.
You still have to do your duties, life isn't that perfect, but they get a little lighter. At least you don't have to carry heavy weights for now.
When I thought about fishmen and pregnancy, I remembered Dothraki from ASOIAF. And I'm not saying they go as far as making you eat a raw horse heart, but some of them may still focus on your diet, like yeah, you need to eat more meat, more everything, some of their specials, to make sure you will give birth to a strong child.
Also, from what I heard, most human-fishmen offspring look more like humans, with only some mild fishmen traits kept, but I suppose there are exceptions as well. And it's clear from the start that it's better for you if the child gets their appearance after a father. Human-looking child... well, it would be a disappointment and you would be pretty much on your own with it, if you wouldn't let them get rid of it.
An idea I read in one of @ofallthingsnasty fics, and I still really like, is Arlong starting to call you a cow once you get pregnant. And some of the crew also catch on to it. Because, in some sense, humans are like cattle to fishmen. Well, not all the pirates think about you like that, but many still like the nickname, even if they use it playfully.
Once you get round and heavy, and you start to waddle, there start happening more jabs about "weak, slow humans". Well, to be honest, fishwomen also get heavier and slower while pregnant, but you don't know about this, and they won't waste an occasion for some funny jokes, right?
If you're still up for it, your lover(s) keep visiting you until the birth. They are still horny, with aching balls, and few other possibilities to relieve that. Besides, while most simply don't mind your rounded state, a few learn that they are actually deeply into it, and the sight of your pregnant belly gets them hard.
And once you start lactating, many want to taste your milk (you're their little cow after all). Which is a bit problematic, because great deal of fishmen have terribly sharp teeth, so you have to watch them carefully, making sure that they won't get carried away and bite your sore nipples.
When you give birth, to a healthy fishman baby of course, there is a big excitement in Arlong's Park. If you can guess the father from the kid's appearance, the new dad beams with pride and gets congratulations from others. But whether you know the specific father or not, there's a party that night to celebrate a new member of the group. For some reason, getting a child with you isn't "mixing with inferior race" or "mixing with filthy human blood" anymore (as a few fishmen whispered before). Now everyone views it as a proof of victory over humans, since you work for the crew and bear them children. And, to be honest, it's mostly seen just as a joyful day - for an evening, political discourse is forgotten, and there's only happiness about their growing pirate family.
Also... once you heal, they want you pregnant again. The previous time, it may have been an accident, but now they saw the possibilities, and they are very eager for you to bear more children. First pro: they get more fishmen for their ranks. Second: they just like seeing you pregnant. So forget about contraceptives. Maybe they will even make a challenge, who's gonna impregnate you this time (Arlong tries hard, because as a leader, he has a priority to pass the shark genes).
Them !! After so long it's drawing them again !! At least I want...
If you don't know Tan or at least don't remember her, Tan is my first One Piece oc she was originally gonna be a self-insert but I changed my mind to make her an oc(in both ways Jinbei was her father figure) this month it's gonna be 2 years since I got this tanuki gremlin
I kinda miss the beginning where I first joined the One Piece fandom... I still love Jinbei but I'm more focused on other characters like Magellan, Sasaki or Kaku
