This is an MPreg story for the ship Zero (also known as Niles) and Corrin (or the Avatar). My version of Corrin is generic, simply the male Corrin that you start off with, although you are of course free to picture whichever Avatar you desire. I am not an expert on pregnancies, not in the slightest, however I do enjoy MPreg stories. I researched as much as I could, but of course there will be some flaws here and there.
So, here's how this works, you can either have this in an Alpha/Beta/Omega Dynamics sort-of-thing, which is what I prefer, despite not adding those aspects in, or you can have it that all royal family members, both male and female, as long as they have blood of the ancient dragons flowing through them, are capable of becoming pregnant.
Nina can be implemented in however you choose, whether she is already born, or she will be born later, or just never there at all. I'm still trying to figure all of that out myself.
I chose the Hoshidan route, so I do not have a chance to bond or get the support dialogue from Zero. I am not sure what happens if you do choose Nohr, so some information may be inaccurate, but please go along. This takes place in the Nohr castle, not the astral plane, due to tension between Hoshido and Nohr being particularly high, and the castle needs as much protection as possible. Corrin and Zero have a surprisingly domestic relationship, and are head over heels for each other. I am almost positive that I put an unreasonably large amount of fluff in this, but I couldn't help myself
There is nothing overly graphic, I don't even think I'm capable of writing anything too graphic, anyways. I hope you enjoy this story, it was very interesting to write, and I hope to write more stories to tie into this one
He had been told to keep calm. Simply relax and do everyday routines, save his energy. This stage would last awhile, and he shouldn't rush off for help immediately. It should last only a few hours. Just stay calm, and have someone near him in case he needed the help. The early labor phase was when he needed to stay calm.
Corrin had sent a messenger to call for Zero, hoping that his lover would distract him from the pressure in his swollen stomach. He had been informed by his messenger, a young looking woman, that he should probably call for his midwife, Felicia, to watch over him. So he did as he was told, Felicia sticking close to his side soon after his call, while Zero wasn't allowed to leave his post until active labor set in.
It aggravated Corrin that Zero couldn't be with him yet, but he knew that they were in a tense time and needed Zero's protection along the castle gates. It would be okay. Felicia was being very kind and caring, albeit still being her clumsy self, and she tried to distract the overly pregnant dragon from his current predicament. She suggested reading to him, helping him clean around the house, entertaining him with music.
He wasn't due for another two weeks, but apparently with twins it was normal to be a bit early. Felicia had done her research on pregnancies and been there for Corrin each step of the way, also informing Zero on how to keep his love safe and healthy throughout the process as they made their way through each trimester.
He was barely able to move around at this point, too pregnant to even support his own weight. He had been told to get rid of his armor only a month into his pregnancy, which he obviously hadn't been thrilled about. He had an army that needed his leadership, but he wasn't allowed to fulfill such duties while carrying. Everyone had told him that they would be fine, reassuring the Prince, but that they would miss him during his time off.
Upon Felicia's arrival he had been ushered out of his common clothes and into a comfortable robe, the maid clearly trying to be helpful without stressing out the Prince as she continued with her comforting words and actions.
His maid had taken him into a special room set up for him, filled with a plush bed on top of a low and sturdy frame, specially crafted for this sort of situation, bars on the side to grab onto and thin blankets to cover him.
Sheets had been strung across the ceiling to make the room seem smaller, the large windows also covered in thin blankets that let little light slip through. Felicia had been informed that pregnant people felt safer in more closed off spaces, small and cozy corners. Despite how much Corrin would like to deny it, the Prince had found himself comforted by the tightness of the area on more than one occasion.
Felicia had suggested that they make the trip down the hall and to his room after his contractions worsened, about five hours after he had originally called for her. She had been by his side most of the time, sending word to Zero when the Prince was resting and saving his strength, which he had been assured that he would need.
They had run into a few people along the way to their destination, including Jakob, who had offered them help. The two had gladly accepted the assistance. Corrin was just a bit too heavy for Felicia alone, and his worsening contractions made it difficult for her to hold him up when they had to take a moment for him to ride out the pain.
Felicia had carefully helped him into the bed when they got there, laughing lightheartedly at his unsteady wobbling. The maid had then proceeded to wave Jakob out of the room, assuring him that they would call for his assistance if needed.
Felicia read to Corrin and exchanged small talk, occasionally stuttering over her words, pausing their conversation when a contraction gently pulsed through his body. The Prince was surprised by how frequently their conversation had to come to a halt at this point.
When in the cozy room, maybe two hours after they had arrived, the Prince's water broke, causing a faint blush to blossom over his cheeks and his words to falter. When asked what was wrong, he stuttered terribly, embarrassment taking over as he mumbled out a soft "I think my water broke."
Felicia was up and out of her chair in a moment, right by Corrin's side, assuring him that it was normal. After exchanging a few words and a soft laugh, Felicia checked Corrin's dilation, much to his still overwhelming embarrassment, and told him that she was going to fetch Zero. Active labor should kick in soon. She would get Jakob if the Prince wanted, but Corrin put his faith in Felicia. She was capable of taking care of him.
Felicia stepped out of the room to talk to the same messenger that Corrin had spoken to earlier, whom had obediently waited outside the fairly large room throughout the time the two had been there. Felicia stepped back in, more along the lines of stumbled in, giving the Prince a reassuring smile after regaining her balance.
His contractions grew stronger, making him fumble with the edges of his thin robe and shift nervously. Zero rushed into the room, standing by his love's side and grabbing Corrin's hand, which the Prince gripped onto in return quite tightly, his body growing more uncomfortable at the pressure blooming in his swollen stomach.
Felicia stepped outside of the room for a moment, thinking that it would be best to give the couple a moment of privacy. When she came back in, a glass of water in hand for the Prince, she checked Corrin's dilation yet again, telling him that with his dilating process and the strength of his contractions, he was officially in active labor.
She told Zero to watch over the pregnant dragon carefully, whispering a few short words to him before announcing that she would be in the restroom across the hall if they needed her, preparing things for the arrival of the chidlren. She told the couple to search for Jakob, who would be close by, if they couldn't reach her for some reason.
Then it was just Zero and Corrin.
