"LEAVE ME!" Luffy continued to squirm as Garp held the boy from the back of his vest and carried him towards his ship. His legs were moving in all directions, even attempting to kick gis j-chan while the old man carried him. "I said LEAVE ME!" he shouted yet again, "I'm an Alpha! You can't make me do what you want!" He practically growled at the old man.
"Presented as an Alpha or Beta or whatever. I do not care! You will become a good little marine, Luffy. There's no other choice for you. Come quietly and all will be well. Make a fuss and my training to turn you into a marine will be much harsher! And what is this about being an Alpha, huh?! I'm an Alpha too! Quit your whining!" Garp glared at his grandson, delivering a Fist of Love and watched in satisfaction as a bump appeared on Luffy's head.
"Shut up! I promised Shanks that I will be Pirate King! I will never be a marine!" Luffy shouted back at his grandfather.
"That red-haired bastard had spoiled you too much," Garp grumbled, "You will be a marine! And that's final! I will be training you to become a perfect little marine"
'Train?' Luffy thought and one could clearly see a light bulb lightening over his head, "Say, ji-chan." He started and Garp looked at him in question wondering what the boy is up to now, "I will think about being a marine if you teach me to be as strong as you!" Luffy grinned his usual 'D' smile and continued, "You always know where to look for me and Ace when we try to hide. Even though I am rubber and other people's punch don't hurt me, your's does! I saw you moving really fast too! If you teach me everything then I will think about being a marine!" Luffy exclaimed.
"Quite observative, aren't you? Fine, I will teach you Haki and Rokushiki," Garp grumbled. Even though he knows that his lovely little grandsons will be killed on sight if their heritage is exposed, he wanted them to be strong enough to handle themselves out at the sea alone. Luffy cheered as Garp said that and pulled the boy back at the ground, taking him to the ship anchored at the shore near Foosha.
Makino had seen Garp and came to greet Garp and questioned where he is taking Luffy. Garp answered, "He will be staying with me from now on, Makino. I already told Dadan and others."
Makino looked down at her 'little' brother and hugged him close and Luffy wrapped his rubbery arms around her and spoke quietly, "Wait for me, Makino! When I come back, I will be really really strong" Luffy grinned at his adopted elder sister.
Three Years Later...
Luffy had spent the last three years at his Ji-chan's marine ship or at Marine Headquarters. During the time, he had met some great people and of course, some not-so-great people - like Akainu. The magma bastard had given him a strange look which Luffy had ignored and continued with his training. He had mastered Haki in 18 months and had spent the rest of the time mastering some of the Rokushiki skills. While he was not proficient in all the 6 techniques, he was able to use some of them with practiced ease. During the time he stayed with his ji-chan at the marine headquarters, the man's subordinate had made it his prime duty to teach the boy how to read and write. He had managed to teach the happy-go-lucky alpha some navigation skills too. Not that he needed them anyway.
A year after he had joined his ji-chan on this journey, he had met a marine that goes by the name Rosinante and his 'adopted' son Trafalgar Law. The two had been saved by his grandfather years before. And even though Law was older than him and wanted to be a pirate, the man had not been allowed by Rosinante to leave the latter's side because of his status as an Omega. The tattoed boy had been rather put out by it and would always pout - though Law would never admit it, Luffy always noticed the signs of it - when Luffy would share his dream with the furry-hat-wearing Surgeon. Luffy had pestered the blooming surgeon to join him on his voyage until the Surgeon had relented, stating it was better to set out under an Alpha his adopted dad approved of than staying locked up in the marine base which he hated with a passion. Luffy had cheered, hugging the omega who had blushed so deep as he had felt the Alpha's scent washing over him. The surgeon had later introduced his now Captain to Bepo, the polar bear he had saved a long time back. Luffy had stared at the talking animal in fascination, announcing that the furry animal will be his nakama, his navigator.
Moving on to the present time, Garp and Rosinante stood at the shore of Loguetown as they watched Luffy, Law, and Bepo departing from the shore in a fucking submarine. They had it made at Water 7 by the Galley-la company workers - a gift from their respected marine family members who stated if they were going to be outlaws, then they better have something that will keep them safe, even in extreme conditions. Luffy had pouted, wanting a ship but Law had been adamant on it. He finally relented when Law showed him what all they could do with a submarine and how it was the best option for them. He might have thrown a fit - not that Law would ever admit to that.
As the three moved inside the submarine as it dived under the water, Law asked Bepo to take control of it, Luffy asking to navigate to Dawn Island, wanting to meet Dadan, Makino, and others. It would take them rather long to reach after all, even with the sub. Law leaned against the wall of the sub, feeling feverish as he wiped the sweat off his forehead. Luffy turned a worried glance towards Law, moving closer to the taller man, his hand wrapping around the other's waist, pulling the omega to him. "Not well?" He questioned quietly as Law let out a small moan, his head resting on the Alpha's shoulder.
"I think I missed my suppressant," Law replied as he leaned against Luffy. The boy had grown up in the last three years. He had gained some height and weight. His body structures almost the same as his elder brother, but he was still not as tall as Law.
"Does Torao needs help?" Luffy questioned as he let Law's waist rest on his own and led the elder guy in one of the bigger bedrooms that they had designed. Their submarine was big enough to hold 40 people at a time. Not counting the are which Law had reserved for his medical work.
"Please," the surgeon moaned as Luffy laid him on the bed gently and locking the door behind him. Bepo was busy with the navigation and steering of the ship. Luffy slipped beside Law on the bed, his hand moving to pet Law's head slowly who moaned at the gentle touch of an Alpha, wanting, needing more.
"Shh.." Luffy pulled the omega under his embrace, rocking the man gently who pushed his hips up, rocking, longing for penetration. "Easy, Law. We did it before, right? Come on. Look up" Luffy whispered as Law stared up at the Alpha who pressed a gentle kiss on his forehead and squeezed his cheek. Letting out a low moan, Law whimpered, "Please. Need more." he moved as close as he can, his front pressed against Luffy's chest, his leg wrapped around Luffy's waist as the younger boy slowly slipped his hand inside Law's pants, his finger finding Law's leaking hole and slipping in slowly. That earned Luffy a needy moan from Law and Luffy smiled down.
"You know what to do, Torao" Luffy kissed the man slowly who rocked on his finger, fucking himself at his own pace, panting hard.
"More" Law breathed out as Luffy slipped in another finger in the man's leaking hole, letting the man fuck himself. He continued to whisper sweet and comforting words in his ear, soothing the needy Omega until he finally passed out from exhaustion. Looking down at the sleeping Omega, Luffy slowly undressed the man, cleaning him with a washcloth and dressing the man back in one of his usual clothing. The two are not essentially the part of a pack. Luffy would help Law around now and then when the latter forgot to take his suppressants. Luffy wouldn't mind mating with him, though. He liked Law. Even if some people might call the surgeon creepy, he had known the man for a long time. He might not show it, but he was a very caring person. As Luffy covered the omega with a comforter, he pecked the man on his forehead, moving out of the room to check on Bepo.
Bepo looked at Luffy and smiled, "We will reach the Gecko islands soon, Captain. It will take some time, even with the full speed." The polar bear then looked at Luffy with wide eyes and bowed, "I'm sorry."
Luffy laughed as he pets Bepo's head, "No need to be sorry, Bepo! We will reach there in our own time."
"How's Vice-Captain Law?" Bepo questioned, worried for the person who saved him.
Luffy sighed before he smiled at the polar bear, "He will be fine, Bepo. He's just tired because he forgot his suppressant. Don't worry. Why don't you cook something? I will keep the sub steady"
"Aye," Bepo answered as he moved towards the kitchen to make a large meal while Luffy kept the sub steady. It was an hour later when the two ate the food. Luffy piled the food on a plate for Law, moving back in the bedroom where he slept. Setting the food on the table beside the bed, Luffy gently woke the sleeping omega who looked at him sleepily.
"Come on, Torao. Time for food," Luffy grinned at the sleepy omega, pulling him up and against his chest as he fed him slowly.
"Luffy-ya," Law mumbled after he had eaten his fill and was now leaning against the Alpha heavily, his head resting on Luffy's shoulder. Luffy caressed Law's head slowly, his furry hat resting on the table along with the leftover food. He hummed as Law continued, "I would like to mate with you," the elder guy whispered, low enough that Luffy almost missed it.
Luffy turned his shocked face towards the man and questioned, "Torao. You're in heat. I won't mate with you unless you tell me when you are in control."
Law smiled at the caring Alpha, his lips pressing against the said Alpha's neck, "Please? I need it so much, Luffy-ya"
Luffy shook his head vehemently, "No. Not unless you want the same thing when you are in control, Torao. I will help you, but I won't mate you until later."
Law sighed, sinking back into the Alpha deeper, aching so much. Luffy's touch calmed his sub sex but it was not enough. He wanted more. So, so much more than the simple touch. Luffy slowly worked to undress Law, his hands caressing the omega's body, his scent thick as Luffy tried to calm down the omega. He wrapped his hand around Law's waist, holding him protectively as he made work to slip in his finger inside Law's slick hole. The omega moaned at the feeling of intrusion, his hips rocking slowly as he rode the finger, wanting more. Luffy didn't move his finger but moved his other hand to pet Law as the omega moved. The Omega had turned around in his grasp, facing him and resting his head on Luffy's shoulder, riding the Alpha's finger with a fast pace. His moans filled the room as he latched on to the Alpha. He wanted to mate. He wanted an Alpha's cock pushed deep in his hole, not a measly little finger. He wanted the throbbing mass to take the one thing he had never given to anyone else. He wanted it, yet he could not get it. He understood though. He understood Luffy's hesitation to take his words at present. He was far too gone to care about anything else but sex and food. And he was grateful for the Alpha to not take advantage of his condition. And that was the reason he agreed to follow the rubbery alpha.
With a final movement, Law came hard on Luffy's clothed chest, white ropes of cum leaking from his tiny cock as they landed on Luffy's vest. Panting hard, Law slumped against the Alpha who cleaned him up, this time pushing the naked man inside the comforter, letting the omega ride the exhaustion out.
This continued for two more days until Law's heat finally ended. The man had blushed deep when he had caught sight of Luffy the day after his heat had ended. Luffy had smiled at the blushing man, walking closer to him as he pressed a sweet kiss to his forehead, telling him if he still wants it, Luffy was okay with it.
Before he could answer though, the sub had sighted a sea king closing in on them. Luffy ordered Bepo to pull the sub up. As the submarine finally reached the open sea, Luffy dashed out, glaring at the sea king. He smirked at the monster and stretched his arm back before he punched the sea king, sending him flying. Taking in a deep breath, he stared at the blue sea before he asked Bepo if they could travel like this for some time.
As they traveled like this, Law made his way out on the deck where Luffy stood and whispered something in Luffy's ear, blushing deeply. Pecking the blushing omega, Luffy smiled at him wide, pulling the man to his chest before he kissed him hard. "Tonight" Luffy whispered against the blushing Omega's lips and grinned cheekily.
