Chapter Text
The second that Luffy saw Zoro tied up in the marine base, he knew the omega was his fated mate.
“Join my crew!” Luffy cried out to the omega before untying him from the wood post he was roped onto.
“You’re my fated mate…” Zoro said while sighing after being untied by the alpha.
“So you noticed.” The alpha said laughing cheekily.
“My names Luffy and I’m gonna be the king of the pirates as well as your future mate.” Luffy said boldly.
Zoro eventually accepted joining the alphas crew as his first mate, and they both departed on a small ship into the sea.
After they were on the boat, Zoro forgot one crucial detail of something that would be happing in just one day, his heat.
After meeting Luffy and joining his crew, Zoro knew he would be spending his heat with Luffy anyways, but he didn’t want to spend it on a boat with no cover in the middle of the ocean.
So, Zoro sucked it up and thought he’d mention his heat starting tomorrow to Luffy, just to see what he wanted to do.
“Hey Luffy, can I tell you something?” Zoro said letting his pride take a backseat.
“Yeah! What is it Zoro?” Luffy asked looking at him curiously.
“My heat is starting soon, do you know when we will make it to the next island. I would like to not spend it on the boat.” Zoro said cheeks turning red as he judged Luffy’s reaction.
“Hmm I’m no navigator! I’ve really just been going in one direction hoping we see an island ahead!” Luffy laughed, “If Zoro has his heat I’ll take care of him.” Luffy said smiling at Zoro.
Zoro sighed as he noticed Luffy releasing some of his calming alpha pheromones to calm Zoro’s nerves about his upcoming heat.
That night when Zoro went to sleep he could feel the heat creeping up on his cheeks as he thought that hopefully they would make it to an island by tomorrow.
When Zoro woke up in the morning he felt the sweat dripping off his body, and silk flowing from his hole.
Then Zoro noticed he was in a different place than the boat, some kind of room.
“Alpha!” Zoro called as he frantically looked around the room and noticed Luffy looking outside the window of the hotel room they were in.
“I’m here.” Luffy said as he walked over to Zoro, putting his hand on his cheek and rubbing it softly.
“Looks like your heat has hit you full on.” Luffy said as Zoro moaned, Zoro felt so sticky and needy.
“Where are we?” Zoro asked with his last ounce of consciousness.
“I spotted an island last night after you feel asleep, so I stopped here and carried you to this heat hotel.” Luffy said as he started rubbing his hands through Zoro’s short hair.
“Thanks.” Zoro said as he thought about how caring of an alpha Luffy is and how great of a captain and dad he would be.
Zoro groggily sat up out of bed and started to strip off all his clothes as Luffy sat and watched him carefully.
“My omegas so strong.” Luffy said smirking as Zoro stood completely nude and leaking from his hole onto the floor.
Zoro quickly got on the bed and presented for his alpha, feeling his desire to have Luffy inside him well up.
Luffy growled deeply watching his omega present for him so prettily.
Luffy could feel his knot starting to get bigger and knew he should probably mount Zoro as quickly as possible before his knot pops right then.
“Alpha I need you.” Zoro sung out as Luffy quickly got behind Zoro and lined up his member into Zoro’s leaking hole.
Luffy slowly pushed in groaning as Zoro whined for more.
Then in one quick push Zoro felt Luffy finally fill him all the way up inside.
“Ahh!” Zoro yelled out covering his mouth afterwards in embarrassment.
“Be as loud as you want Zoro, it’s a soundproof room.” Luffy said giggling as he slowly moved back and forth inside Zoro.
Then Luffy changed the pace and started relentlessly pounding into Zoro, making the bed sway.
Zoro could feel Luffy’s knot catch his entrance after a minute of Luffy diving hard into him.
“Want you knot alpha, please! Give me your pups and your bite.” Zoro cried as Luffy pushed his knot into Zoro’s entrance making a pop sound.
Then Luffy quickly bit down on Zoro’s mating gland behind his neck, marking Zoro as his forever.
Both Zoro and Luffy released their load at the same time, panting as hot liquid seeped out of Zoro’s hole and onto the mattress beneath them.
While Luffy and Zoro were still connected by the knot, Luffy fell ontop of Zoro, pushing him into the bed.
“How long does this thing last?” Zoro mumbled, his face being squished onto the mattress.
“Just a couple minutes more I think.” Luffy said as he felt his knot slowly deflating.
After a couple minutes Luffy pulled out of Zoro, leaving Zoro feeling empty as ever.
“My omega.” Luffy said squeezing Zoro tightly into his chest on the bed.
“My alpha.” Zoro said as he rested his head into Luffy’s strong chest.
After a few hours passed and they both felt recovered Luffy and Zoro headed out of the hotel as mates.
Then they explored the island a bit, they found a redhead girl named Nami to join there crew as a navigator and they fought a crazy pirate clown named Buggy.
They eventually left the island as 4, Luffy, Zoro, Nami, and the unborn baby inside Zoro’s stomach waiting to cause a scene once they notice he’s there.
