Hello and thank you for clicking on my fic!

First off, yes. This is an Omegaverse fic. If the title and the summary wasn't clear enough.

No I am no expert with Omegaverse whatsoever so please do bare with my lack of knowledge on the subject. This is going to be my first attempt touching this subject. If I do mistake something from the lore, feel free to tell me, though please no flaming guys.

Yes this is a threesome/triad pairing fic consisting of Alpha!Lucci, Alpha!Kaku, and Omega!Coby. If you have no idea who any of these three are, I suggest you watch the whole of Water 7/Enies Lobby (It's a great arc, I swear).

Perhaps some of you would think that Coby would be an unnecessary addition to the pairing (Lucci x Kaku is a much more common thing and all) or you might think he fits better with Helmeppo (Cobymeppo is also a very common ship) but this is my story, I love Coby, I do not like Helmeppo all too much, I ship them better as bros more than anything, and two friends of mine has cursed me into getting into such an absurd rare triad ship that I'm pretty sure we're the only people to ever ship it or see the potential in it.

What else should be said... Ah, right. This is a modern day setting, the relationship has already been established beforehand.

Enjoy~

"Are you sure you're going to be alright?" Kaku asked as he looked over to Coby.

"I'll be fine, you've been asking this for too long." Coby laughed as he handed them their luggage. "It's only a five days retreat right? I'm an omega, not a helpless lady." he huffed a little.

"You can't blame him for asking a lot." Lucci claimed holding his own luggage, his usual feathery companion contently perched upon his shoulder. "You might be strong, but your initial appearance isn't a match to your strength." he claimed.

"Gee. Thanks." Coby mumbled stiffly while Kaku just chuckled. "Anyway, I'm going to be just fine. If you're worried then you can call me every night." he assured, as he placed a hand on Kaku's cheek and gave him a kiss before turning to Lucci and doing the same.

They just got out the door and into the hallways of the apartment building when Kaku turned around. "Just make sure you lock the door."

"Kaku." Coby sighed.

"The number to our inn is on the fridge if you can't contact our phone."

"Kaku..."

"If they claim to be a delivery guy, just tell them to leave it by the door."

"Kaku."

"Also-" Kaku didn't get to finish that one as a highly annoyed Lucci had enough and grabbed him by the collar. Pulling him away from the door and down the hallway to the elevator.

Coby sighed as he just watched them fondly. "Bye, love you two!" he called out shamelessly, just smiling in amusement at the thought that it probably got Lucci to be flustered, it always worked.

Once he saw them go into the elevator, he closed the door behind him and locked it as he was asked. After that, Coby just stretched out his arms and walked over to the living room of their shared apartment and went over to the couch, flopping right onto it. He looked up at the ceiling for a while and just sighed to himself, feeling very at ease. He stayed like that until five minutes later when his phone rang. "Hello-"

"And do not trust the milk man!"

"Bye Kaku!" Coby said and hung up on him, turning his phone off and throwing it to the armchair. Once that was over with, Coby turned to his side and curled up a little. Now that Lucci and Kaku were gone, he wondered what he should do.

And while thinking of all of that, he found himself drifting off into a bit of a nap.

The next time he woke up was to the sound of the clock on the wall going off, telling him that it was the next hour.

Coby groaned at the sound of it, feeling himself to be a little too sluggish and hot. Wasn't it the middle of autumn? When did he even turn the heater on? Goodness was he wearing some thick blanket?

He groaned again as he pushed up, only to realize there was nothing on him. Still he felt sluggish, almost overly so, but he wasn't beyond functioning. Getting up from the couch, he looked at his surroundings before heading off to the door leading to the balcony. Sliding it open, he shivered when the cool breeze touched his skin and it made him close the door again. Leaning his forehead against the glass of it lightly he looked at the small bit of reflections he could see of himself, and realized...

He had just entered heat.

"No… no no no no." he muttered as he pushed himself off from the glass and headed for the kitchen. God, Lucci and Kaku just barely left and he already entered into heat? What kind of sick joke was this? "Suppressants, Suppressants." he mumbles to himself, trying to keep his cool, but his body was just so hot.

Stumbling to the kitchen, he went for the cabinet where they kept the first aid kit. He had to quickly take suppressants before it was too late. He wasn't like some who has lesser symptoms at first and gradually grew stronger. He was the opposite, his symptoms, his scent starts out stronger right from the go, in a matter of some hours, sometimes even minutes.

He growls a little in irritation as he couldn't get the locks on the kit to open quickly, but once he does, he cheers silently to himself.

He opens it, only to flinch as he finds that there were no bottles labeled suppressants.

Coby was confused, he doesn't think he's run out yet. He doesn't remember if he ever ran out, and when he does, either Kaku or Lucci reminds him to buy more.

Had someone stolen it? But who would steal heat suppressants, you could get them at any drug store-

Oh.

That's right.

He gave his bottle to Edgar a few days back!

What should he do? Should he go buy some more? But his scent was growing stronger by the minute, even he could smell himself. If he'd go out there, he was screwed, quite literally.

"I-It's just one or two days… Just two days and I'd be able to go out…" Coby mumbled to himself. Deciding that he could handle two days. It wasn't the first time. Though unbearable, it wasn't exactly un-doable.

Sighing to himself, Coby placed a hand to his head as he panted. His sight blurred just slightly and god, he was starting to crave for a touch. Just place a hand on his back, hold him, whisper soft words to his ear…

Maybe even more.

Coby whimpered helplessly to himself as he shrunk down to the kitchen floor. God, he wanted Kaku and Lucci to touch him.

Another hour passesd as Coby stumbles around the house. He'd tried to keep himself on the couch, not finding the strength to even go to the bedroom. He groaned and whimpered before he panted hot breaths. A hand clutching onto his shirt while the other held the arm of the couch.

"Kaku… Lucci…" he moaned out between pants, as he imagined what they'd do to him if they were around right in that moment.

The mere imagination made him bite his lower lip, his needs were so strong it was starting to feel painful, almost suffocating.

At least he was sure no one would be visiting.

That thought was immediately shattered when the doorbell rang, causing Coby to shoot up in a startle.

"Hey Coby! You home? Came to bring back your book!"

The voice belonged to Helmeppo and it caused his stomach to drop.

Helmeppo was a beta.

Oh god, he can't be around someone higher than an omega right now.

Especially not Helmeppo, he was one of his best friends, that was just wrong.

Looking around frantically, Coby hoped to god that Helmeppo would just think he wasn't home and leave.

That was also not to be.

"Guess he ain't home… If I remember correctly, Coby keeps the spare key right over…. Aha!"

Now was definitely the time to panic. He got up from the couch, intending on hiding in the bathroom. Sadly, his legs lost their strength the moment he stood up and he fell down to his knees, holding onto the arm of the chair as his instincts seemed to take over him.

Helmeppo was at the door.

A beta was at the door.

God, he needed something.

Anything.

Unlocking the door, Helmeppo opened it, only to flinch at the overwhelming smell of someone in heat. Covering his mouth a little, he peeked into the room. "Coby?" he called, taking just a small whiff of the air before going right in. He placed the book by the table before he advanced further to the living room, finding his pink haired friend slouched over and holding onto the arm of the couch. "Co...by? You alright?" he called out, seeing clear symptoms of heat. Despite being friends for literal years, he doesn't think he's ever seen him in heat before. He didn't know how to react.

Should he call for help?

Should he get some heat suppressant?

"Hey, Coby-" Helmeppo placed a hand on his shoulder and felt a flinch.

That was the first and only mistake he made here, for the next moment, he was pulled down roughly to the ground, on his ass and elbows. "Coby- what the hell-" he couldn't finish what he was saying as Coby didn't even answer, instead he'd crawled right on top of him, straddling him.

Oh god. Oh GOD. Oh hell no. This was not happening. This was so not happening.

Oh god! Lucci and Kaku was going to murder him.

They were going to murder him and bury his body somewhere in the mountains where he'll never be found.

He grew paler and paler with every thought, it went up to the point where he was ready to shove Coby off of him, but a hand was gently placed onto his chest, pawing it in a gentle needy manner.

"...Helmeppo." That voice came out so sinfully between pants. So full of need, and his eyes were glazed with a haze one could only ever describe as lust.

The mere sight of it caused Helmeppo to get tongue tied.

Though, what really done him in was when Coby leaned down... And started to fucking nibble on his neck.

Helmeppo thought his mind was about to malfunction as he felt the younger man's teeth graze against his skin, only to be followed with a slow little lick and ending with a bit of a kiss. He couldn't stop the blush that came to his face.

What the fuck was this?

It was all so erotic.

He's never seen Coby like this before. Never!

Coby continued with the motions, softly biting, lapping up the spot and repeating the motion, sometimes leaving a fluttering kiss behind before moving to a new spot.

It caused Helmeppo to bite his lower lip as he considered what to do. It was obvious that his friend wasn't in the right mind. He was just dazed from the heat he was under. But it didn't even seem like Lucci or Kaku was around.

The smell was starting to get very tempting, even for a beta like him. Coby's actions were only helping him feel tempted.

...

...

...

"Fuck it." Helmeppo mumbled as he pushed himself up further so that he was properly sitting up. He pushed Coby off just a little, causing the omega to whine. Then he'd allowed a hand to travel down, all the way down to the younger man's hips. His other hand traveling up, sliding up his shoulder, his neck and all the way till he was cupping Coby's chin.

The motion caused Coby to shiver. Feeling a bit of the touch that he so desperately needed.

It was only a kiss, Helmeppo told himself. Nothing more. A kiss wouldn't hurt. Just one. It might even relieve Coby a little.

So Helmeppo leaned in, ever so slowly to bring his lips down to the awaiting perks in front of him.

Only, he was interrupted when a hand grabbed him by the back of his collar and roughly shoved him away, straight to the nearest wall. From the sound of the impact alone, you could imagine that he was going to have a very nasty bruise.

"Hey what's the big de- Gaah!" Helmeppo couldn't help but shriek as a foot was slammed onto the wall, far too dangerously close to his head. Looking up, he shrunk back as he was met with the angry scrutiny of Rob Lucci himself.

"Explain yourself." he demanded, his voice not betraying the rage his eyes showed against the beta beneath. Behind him, Kaku had gone straight to Coby's side.

"Coby, Are you alright?" Kaku asked the omega as he picked him up from the ground, only to have his mate immediately wrap his arms around him and bury his nose onto the crook of his neck. If the thick scent in the room wasn't a dead give-away to the fact that his mate was in heat, the sudden affection definitely did.

"Talk." Lucci demanded further, this time with a slight growl behind his words.

"W-w-w-wait! It's technically not my fault!" Helmeppo tried to defend himself. "I just came in to return his book! Coby's the one who came onto me! I didn't even know he was in heat or that he was home! The whole place smelled sweet and I found him on his knees, I swear! He straddled me and began to attack my neck! What the hell was that even about?!" Now he was just rambling, the fear for his very life taking over him.

Lucci raised an eyebrow at the last part.

"Lucci."

Lucci blinked before looking over to Kaku, only to find that Coby was doing the exact same motion to Kaku as what he may have been doing to Helmeppo earlier, this time, letting out a few soft moans. The scent of one of his mated alpha causing him to lose himself deeper in his want.

"He's at his peak. He doesn't even realize he's begging yet." Kaku told the older alpha, looking mostly amused by what was happening, though the light tint to his cheeks gave out what he was feeling from Coby's little actions.

"He's begging?!" Helmeppo asked, clearly flabbergasted by this.

"Oh yes, we figured it out after the first heat with him, you see. He doesn't like begging with words, instead he get's affectionate to the point of nibbling at your neck… It's a very effective tactic, I assure you." Kaku helpfully explained.

Helmeppo could only stare until he felt someone grab him by the collar again and drag him across the room. Soon enough, he was thrown out of the door and to the wall, his body sitting upside down from the momentum of the throw.

"If you're smart, you won't come back unless you want your head to roll." Lucci threatened as he slammed the door loudly.

The sound of the door slamming shut, caused Coby to flinch back to his senses, even for a short while. He looked up to see Kaku and when he heard footsteps, he looked over to see Lucci. He blinked at them in confusion, even noticing that Kaku was currently carrying him bridal style, causing him to flush more so than he already was. "K-Kaku? Lucci? What are you guys doing here?" he asked.

"We met with that friend of yours at the station. He gave us your pills saying you lent it to him." Kaku explained. "We tried to call you several times, but you wouldn't answer, so we came back to check if anything happened." he explained.

"From the looks of it, you turned it off." Lucci claimed as he looked over to the armchair and spotted the phone that's been clearly turned off. "If we'd been a second later..." he seemed to bristle at the thought, causing Coby to sweat, just a little.

"I- uh- why are you so angry?" he asked, confused as a button.

"What? Do you not remember what happened?" Kaku asked with a raised eyebrow.

Coby looked up at Kaku, still confused. "Um uh...I remember hearing the doorbell and Helmeppo's voice, but other than that…" he mumbled as he placed a hand on his head, oh god thinking back on it made his body ache with heat. Though being held by Kaku allowed it to calm, just slightly. "N-Never mind that, what about your train? The retreat?" he asked them looking more worried about their plans than his own state.

"Don't worry about that Coby." Kaku tried to reassure him. "You don't quite expect us to actually leave you in this state do you? Kalifa, Paulie and the rest will understand. It's just a company retreat."

Coby looked at them with worry. Looking very unsure as he shrunk. "But…The company's been planning it for weeks and you all worked really hard to get these five days off and...I-I don't like being in the way of that..." he mumbled.

"Coby…" Kaku called as he watched the man in his arms.

Lucci looked at Coby and noticed he was already fiddling with his hands. A little motion he's come to spot whenever the younger man was anxious. Without so much as saying a word, he walked right over to him and took something out from his pocket. He retrieved the bottle of pills and placed it in Coby's hands. "If that's what you want, then I suggest you quickly take those pills, get some rest, and we'll be on our way. We only did come back to check on you, and to deliver them. Let's go Kaku." he claimed as he turned around to start heading for the door.

Kaku looked at him disapprovingly, was he for real?

Coby also looked at him, eyes wide as he held the bottle in his hands. Opening his mouth, he closed them again and repeated the action as Lucci just continued to walk. Though, before he could get out of arm's reach, Coby reached out and latched onto his coat, holding it tightly in one hand.

Coby hated begging, he disliked it with a passion, at least with words. It was simply something he didn't like doing, but… but…

He was needy! He was in the peak of his heat! He wanted to feel kisses. He wanted to be held. God only knows, he needed to be fucked!

They were right there. His mates were right there, and there was no way in hell that Coby was going to wait agonizingly slow minutes while the suppressants did their job. He wasn't patient for that, not anymore.

They were right there!

"Stay… I-I don't want you to go. I don't want to take the suppressants. I want you guys… Please Lucci, Kaku. Don't leave me alone like this. Not now... Please." the words came past his lips in something just barely above of a whisper. Tears gathering in his eyes from the frustration of it all.

Lucci didn't say anything for a few seconds, though as Coby repeated that last word just a few more times, he'd finally turned around while sporting a smirk. Satisfaction was dancing in his eyes.

"Lucci, you cruel son of a gun." Kaku commented with a light glare as Lucci came back over to them, holding the wrist of the hand that had been holding onto his coat.

Lucci leaned down to plant a kiss upon the omega's forehead before looking up to meet the eyes of his unamused alpha mate. "Thank you." was all he said as he took the bottle of pills away and set them onto the table, taking off his coat to place on the very same table.

"I didn't mean it as a complement." Kaku told him bluntly, though as Lucci walked over to where their bedroom was located, he followed the demon into his lair with a roll of his eyes.

Thank you for reading part one! Now before you go off to part two, I suppose there may be some questions I need to answer.

If you have further questions, don't be afraid to ask.

If you've spotted the name "Edgar" in the fic, that is not a character canon to one piece. It is actually a character my friend created whom we are shipping with Sabo. Yes, you heard right, we're shipping a canon character with an oc, it's not the end of the world, get over it. If in any case you will not be seeing any lines from Edgar or Sabo in this fic, they are only mentioned, worry not.

This fic was originally written only to be seen by the eyes of my two friends who got me into actually writing smut and got me hooked onto the pairing I am using on this fic.

I am fully aware that there are different lores on omegaverse where a mated omega will not be able to have sex with someone other than their mated Alpha. In this case, I have no idea what I'm going for, there's too many to choose from, sue me.

If anyone is wondering where the fuck Hattori disappeared to, you will find out in the next chapter.

Thank you for reading part one, off you go to part two. That's where the smut is at, I'm still not confident in my abilities to write decent smut, so you have been fairly warned.

For now, I bid you all, Adieu~
