"Dada, dada!" Gawain held out his arms for him, and Law picked him up, swinging him around to hear him shriek in delight.
Kid smiled up at him from his lazy sprawl on the grass, one hand keeping Caterina from toppling off his shoulder where she sat playing with the Omega's hair, the other keeping Daveth and Mattias occupied with its intricate arrangement of bolts and springs.
The Omega had done a lot of work on the arm to make it childproof, and Law sometimes wondered just how much was left of the original. It couldn't be much more than ten or fifteen percent, but it was sophisticated and elegant now and took much less toll on his mate's body and balance. It was a work of art with its fascinating design of elegant machinery and deadly weapons only the Omega knew the full workings of. Law could spend hours looking at it, tracing every bolt and screw trying to guess their exact function. It was beautiful and practical and Kid was rightly extremely proud of it. He had an amazing talent for machinery.
Law'd been concerned when Kid enthusiastically told him about all the features he was hoping to implement, worried it would be much too big and heavy and his mate wouldn't have full use of it, but his concerns seemed to have been unfounded. He knew Kid would never use it around the kids if it wasn't completely and utterly safe, but he still insisted on looking it over weekly to make sure everything was all right. His mate humoured him, and even let him look his shoulders and back over regularly to confirm there were no signs of complications. Law thought his compliance probably had much more to do with the massages he gave him afterwards than actual concern, but he didn't mind. Kid was always very pliable after a good massage and could be persuaded to do or let him do almost anything. Even the medical examinations the Omega hated.
He shifted Gawain to a more secure position as he sat down next to his mate. Caterina scrambled down from Kid's shoulder, reaching out a chubby hand. Law took it, smiling, letting her lift it up to her face so she could smell his wrist. She was the most Alpha of the bunch, very secure in her instincts that told her any Alpha who approached 'her' Omegas – Kid, Gawain, Heat, and Penguin – had to be checked for familiarity despite their appearance. Kid meant to break her off the habit as she matured – and Law agreed – but he felt those instincts should be honed and trained. She had talent, it was obvious, and he was sure she'd show more signs as she grew older. Kid was sceptical, but uncharacteristically told him he was the Alpha and he probably knew more about Alpha instincts that he did. Law still hadn't managed to get Kid to tell him where that came from.
Caterina let his hand go, nodding, after a thorough scenting and climbed over her brothers to settle on his lap, nuzzling at her brother's neck. Gawain tilted his head, letting her scent mark him without complaint, pulling her into a hug.
Kid leant in for a kiss, and Law returned it, eyes seeking the Omega's bump.
They were going to have such a big, strong, beautiful family. The Alpha in him wondered how many children Kid would consent to bear him, and Law let him.
Ten seemed like a lucky number, but he doubted Kid would agree.
