Witch68 - Oooooh neat to be the first experience on an Omega Marco story haha, thank you for reading it! There's really not a lot of them, you'll find a few if you search for them, but they're countable on like two hands. Ah! I know right!? Each and every gender got their own struggles, like... you all in the same boat, why you all being like this to the Omega's especially!

WinterRose61 - Hahha must have been a fun little surprise for it to suddenly be Marco who's the Omega instead of Ace haha. Marco likes to ramble to himself about things. He's a great person! So nice to everyone, not judging on gender. And yea! I think Pops would treat Ace like a baby even in canon hahahahahah Best grandpa there is. Thank you for reading and enjoying a lil Omega marco!

(THIS IS A HAPPY STORY! Even if the title maybe sounds like things are about to go wrong. Don't worry! This is an happiness series only!)

Soooooooooooooo! I said I would update Dark Flames. I lied, apparently. Didn't know myself up until now that it would become a lie. But well, the story's happy part that I had planned is a lot longer than I anticipated. So I'm splitting it up. From the title you can already clue in or get a hint of where I'm going to go with this in the dark flames. But for now, enjoy the normal Omega-verse update and just pure happiness of our cute Omega Ace and Alpha Marco.

Concerned Marco stood next to his omega, rubbing over his back and holding him steady as the other stood on tiptoes bent over the railing, ugly puking sounds heard over the deck.

Thatch was freaking out not far away, apologizing for the millionth time for this must be his fault. He had used some weird looking meat he had found at the last island, the islanders having said it was safe if he boiled it, themselves eating it often.

Ace being the meat-lover that he was, was of course the first to stand in line to try the new dish, only... to grow deadly pale minutes after eating the first test dishes Thatch made and running out of the kitchen. Marco instantly running over to him, ignoring the conversation he had been having with Pops. This bringing them to their current situation.

"Love..." Marco spoke softly as Ace let himself slump to the ground, going down with him and pulling him against him. "Is it over-yoi? Are you feeling better?"

The smallest nod came from the other and Marco helped him stand up on trembling legs. "Let's go to the infi-". He was interrupted by Ace bending over on himself again, trying to turn back around, but not making it over the railing before he fell to his knees, puking what was probably the very last he had in his stomach over the deck.

"I-I'm sorry, I'm sorry" Ace apologized with tears in his eyes as he looked at the mess he made. His stomach hurt, his throat hurt, his stupid omega was happy for who knows what! Yes, the meat was good, but this isn't fun Omega!

Marco was there seconds later, picking him up like a little koala-bear and holding him again him, not caring that puke may get on his shirt. "It's okay, it's okay" he released some comforting pheromones, glad Ace melted a bit more into him at that, "Let's get you to the infirmary. They'll be able to help you." He gave a kiss to Ace's temple and rubbed his back, looking to Thatch in the progress and nodding towards the puddle of vomit. The chef instantly nodding in return and already going to their small cabinet they had outside with cleaning material as he himself walked inside to carry his sick mate to the infirmary.

"It tasted good, Marco."

"I know, baby. You know Thatch, he could probably make garbage taste like a 5-star meal-yoi."

A small laugh came from the raven on the infirmary bed, "he probably could."

Marco sat beside the bed, holding Ace's hand and stroking over it. His mate was feeling a bit better already, having gotten some basic meds to fight a possible food poisoning. Now they were just waiting for some blood tests, the nurses having taken some just to be sure.

"Commander."

Both of them hummed, making the nurse flush a bit, "Ah ehm, I meant Commander Marco."

"Yes?"

"Could you please leave us for a minute."

A frown came to his face, the nurse was carrying a chart, so obviously with the results of the test. "Is something wrong with Ace? My mate? What's wrong-yoi?" He jumped from his chair, trying to see the chart the nurse was hiding.

"Commander, please. It will only be a minute. I promise Ace is fine."

"Then why do I need to leave." He wasn't going to leave his mate all alone when he didn't even know what was going on!

"Alpha" Ace smiled gently at him, still lightly holding his stomach, "It's fine. The nurse said it was fine. You can join back in a minute. Right?" he turned towards the nurse who nodded.

Reluctantly Marco nodded back, not wanting to stress his mate by staying either. Before he left he took a few seconds to nuzzle against the crook of Ace's neck, scenting him much to Ace's glee. He knew he didn't have competition on the ship, but still he scented Ace, especially at times like this. Not only would others know not to mess with him, but it also calmed the Omega down to smell him on their mark.

"So, Commander Ace." The nurse started when the infirmary doors closed, "I actually have good news and... extra good news."

"Huh? Ehm, I'm not sick?" Because what else could it be.

"You're indeed not. You weren't sick from foodpoisonig at all."

"Then what?"

"It was morning sickness" the nurse smiled.

"W-what?" he knew what it was, he knew what it meant, his Omega that was already purring in delight definitely knew what it meant and he could feel his own happy scent already escaping him.

The nurse giggled at the conflicting reactions. The commander's normal thinking still a bit confused, while the Omega side is already celebrating.

"You're pregnant, Ace. About 6 weeks along now."

"Si- six weeks." he looked down to his stomach, hand tracing over it, "I'm... I'm growing a pup?"

"You sure are, Commander. Congratulations."

The nurse chuckled as Ace tried to speak but couldn't due to have become a purring mess, the rumbling sounds tearing from him, interrupting his every try at it.

"Shall I let Commander Marco back in?"

"Y-Ple-y-" He furiously nodded instead as words failed him.

The moment Marco entered, the nurse staying outside to give a bit of privacy, Ace jumped out of his bed and into the blond's arms, nuzzling into him.

"A-alp-alph-a, Alpha"

Marco didn't know what was going on, but the whole room smelled of happy Omega, his own mate's happy smell. So of course he purred softly and released his own scent in return as he hugged the other, rubbing his cheek over raven hair as he enjoyed his own nuzzles.

It took a bit of time for Ace to snap out of his happy trance and let go of Marco in favour of standing before him and cradling his stomach, Marco looking a bit confused at the gesture before Ace spoke, with trouble holding back his purrs to finish his sentence.

"Alpha. I'- I'm preg-pregnant."

Marco's mouth fell open, looking between Ace's face and his stomach. "Pregnant. That- that means you're- we- our mating-"

Ace nodded, "Our last mating was a- success."

"Pup." Was the one word leaving the blond's mouth after a minute, "Pup, You're carrying my pup?" Marco already let out a laugh before Ace could nod, surging forward to lift his Omega in his arms and kiss his breath away.

Even if he was an Alpha, he couldn't stop his own purring as praises left his mouth, "My beautiful Omega, perfect, perfect mate. Having my pup. Going to be so pretty when you get round. Love you. Will take care of you. Keep you safe."

"Ma-ar haha marrrrrr!" Ace laughed as he was nuzzled everywhere, his Alpha covering him in his own scent, he barely smelled himself anymore. He didn't mind it, but it tickled! "A-alpha! Smell like you already!"

"Hmmmmmm yes." The blond hummed, voice obviously that of the Alpha, "Will scent you-"

"Hahaha You already did! I don't even smell myself."

"More." he nuzzled the other, rubbing cheeks together, "My puppy, my Omega... nest... Need to get your nest."

With a yelp Ace's feet left the ground and he was carried out of the room and towards the commander's chambers. The nurse calling after them, probably to give them more info, but to Marco it all fell on deaf ears as he carried his mate to their nest to get him comfy. Ace yelled a small apology back and a promise to return later, something the Alpha already grumbled too.

Being enveloped in his Alpha's smell continuously, being scented and nuzzled into over and over again, the words of praise about their puppy, how good of an Omega he was, everything. It didn't take a lot for Ace to let his own Omega take over again as they made their way to their room.

Getting to the room he let himself, for now, be locked inside and put into his nest. It now clear why he had craved to sleep in one since last week instead of their normal bed.

His Alpha was doing everything in his might to get him comfortable and gather all the pillows and softest blankets they had around to put around him and cocooning him in before joining in the nest. Wrapping around him and using his bigger body to shield his own smaller one from the outside world. Protected from all possible dangers. In the safety of his Alpha's arms, the Omega lulled into a peaceful state. He almost felt as if he was floating in a dream, yet still awake as he felt himself purring into Marco's chest.

Many probably already knew that at least something was going on. Their combined intense smell covering their whole tracks and he's sure Marco had pushed some poor crewmates aside to pass as he murmured about how good of an Omega he was an about pups, so the spreading of that info wouldn't take a long time either. But for now he wouldn't worry about it and just enjoyed his time. His time in the arms of his own strong Alpha, knowing it was the safest place in the world.

This will have some more parts of Marco and Ace going through the pregnancy, only happy things in this serie ofcourse.
