Chapter 1
While it wasn’t strange for Peter to be big on the weekends, it wasn’t the most common either. Since starting school with Harley where Peter tried his best to remain big, at least for some of the day, being little on the weekend was almost for sure.
That was why, after his six am feed, when he woke up once again at a reasonable hour, he was fully big. It was a rare day when he woke up with both parents on either side of him but it seemed today was his lucky day. He gave his pacifier a languid suck as he did his morning stretch. His Dad’s hand came down on his tummy mid-stretch and rubbed in soothing circles. Peter let out a little sigh of happiness. He loved lazy morning wake-ups.
He finally looked up at his Dad and saw him leaning on one arm, looking down at him with that smile that made Peter happy.
“That was a big stretch wasn’t it?” He said softly.
Peter nodded and reached up to remove his paci, “I’m big today.” He replied, with an air of surprise around the words.
Dad seemed to take it in his stride though and just nodded, not stopping his belly rub.
“That’s fine bubba. Let’s get you changed and ready for the day. I’ve to bring your sister to a birthday party sleepover, so you won’t have to come with me now to drop her off.”
Peter wanted to cheer. He hated being stuck in the car while they dropped Morgan or Harley off. It was more that he hated that he wasn’t going with them than being in the car but not having to go today was a plus.
Dad undid his sleep bag and picked him up out of the bed, quietly leaving the room so that they wouldn’t wake Pepper. Peter cuddled into him, loving his morning cuddles, little or big. He had been with Dad and Mom for nearly a year now and had gotten used to what his big days looked like.
It was pretty much the same routine as his little days, but with one or two more freedoms. He was allowed to stay by himself in rooms and even play some video games. He wasn’t allowed to leave the tower by himself or get himself a snack, though. Mom was afraid he would choke and Peter wasn’t brave enough to test it.
Tony placed Peter on the changing table and set to work at cleaning his bottom and picking out his ‘big’ clothes, as Peter liked to call them. Really they were just outfits that were plain in colour instead of graphic tees that he liked.
Peter was content to lay there and let his Dad do all the work, smiling at his Dad when he looked at him. “We just have to wash your face and comb your hair, then you can get your morning feed and you’ll be set!” Dad said to him. It was pretty common for all of them to talk Peter through what they were doing, sometimes even as they were doing it. Peter learned that he didn’t have to respond to them when they did it, but if he wanted to get his way then repeating after them always helped in the long run.
Today he was happy to let his Dad wash his face, even if he did pull away with a whine after a minute. Surely it didn’t take that long to wash a face?
“I know, I’m sorry. Let’s go see what Mama is doing.” Tony wet his fingers and ran them through Peter’s curls. They had learnt this was the best way to keep his hair looking well and Peter hated the brush.
“Mama,” Peter responded, taking Tony’s hand and all but dragging him into their room. Pepper was sitting up waiting for Peter and Tony to return.
“Mama!” Peter said once again, letting go of Tony’s hand to give her a hug.
“Well hello, I think we have our big boy today don’t we?” She said as Peer climbed on the bed and onto her lap, letting him Mom wrap her arms around him.
He nodded into her neck, beginning to root. In the beginning, when he was big he tried his best to avoid it but couldn’t help himself and ended up being pushed into his little headspace. Accepting it was easier than trying to deny himself it.
“Oh my hungry baby,” Pepper responded, laughing and situating Peter so that she could ease her nipple into his mouth. Peter wasted no time, suckling as if he had never been fed, making little snuffles as he did.
Tony sat on the side of the bed while he had his fill, chatting to his wife.
“You’re bringing Morgan right? And what about Harley?” Pepper asked, running a hand through Peter’s curls.
“Harley is going out with some friends from school today, I’m pretty sure. I have some work to do in the lab. I think Petey said that he wanted to finish Schitt’s creek the next time he was big so that’s what he’ll be doing today. What about you?” It was so rare when Peter was big that Pepper and Tony had learned to adjust their plans on a whim.
“I’ll be working from home today so I’ll just be down the hall if Peter needs me, it will give you time to work in the lab. I think Thor and Loki are coming over as well.”
Loki had just gotten his classification on Asgard and was a roughly similar age to Peter, both literal and figuratively.
“Oh right? That will be fun. I’m sure Peter would love a little playmate.” Tony said, rubbing Peter’s back.
Pepper quirked an eyebrow at him, “You don’t think having two little mischievous boys is a recipe for disaster?”
Tony groaned, “I never thought of it that way. Maybe we can avoid them being together?” He joked, knowing that they would never do that. Peter loved making friends with everyone he saw, baby god or not.
“I don’t think Peter will let that happen,” Pepper said, smiling down at Peter as he gazed up at her lovingly. Today was going to be a good day

A few hours later Peter sat on the couch, arms crossed and pouting while Harley and Morgan rushed around trying to get their stuff together. His dad sat beside him and was rubbing his leg in consolation.
“You doing okay bud?” Tony asked while Peter sucked on his bottom lip, a clear sign he was upset.
“Don’t like it. Want them here, Daddy!” He whined, looking to his Dad, hoping he could help him. Dad was Ironman. He could do anything!
Instead, his dad just brought Peter onto his lap and cuddled into him. Peter pushed his head into his dad’s neck.
“I know you do, but Harley and Morgan can’t cancel on their friends. They’ll be really sad if they do. Do you want them to be sad?” Tony asked, and Peter shook his head.
Harley, ready to go before Morgan, sat beside Tony and Peter, looking over Peter’s head their Dad.
“Is he little?” He asked. Peter whipped his head out from his father’s neck to glare at his big brother.
“Not!”
Harley held up his hands in a forfeit, “Sorry, I didn’t know if you were or not. Why are you pouting?”
Peter narrowed his eyes at Harley, “Daddy, I change my mind. I don’t care if Harley goes.” He declared, crossing his arms and turning his head away from Harley.
Tony laughed at Harley’s offended face. It wasn’t often he was on the receiving end of Peter’s anger. Peter normally worshipped Harley and wanted to do everything with him.
Peter stood up from his Dad’s lap, letting Dad hold onto him while he got his footing. No matter if he was big or little. Tony and Harley watched on, amused as Peter stomped is way out of the room.
“Where are you going, Bubba?” Tony called out to him.
“Mama.” Peter always went to his mom when everyone was being mean to him. She would take his side.
He toddled down to the office they kept right off the living room for when Peter was big to find his mom on a zoom call with what looked to be shareholders. Peter didn’t care about that though and walked over and crawled his way onto her lap.
Pepper simply opened her arms for him and helped her baby get comfortable, adjusting the camera so that it only showed her shoulders up. If she knew Peter, it wouldn’t be long before he was rooting. Until then she simply ran a hand through his curls and let him sulk, giving Tony the thumbs up when he popped his head in and jingled his keys to tell her he was going with the kids.
Peter paid his Dad no mind, shuffling down whining until Pepper adjusted him and undid her blouse, giving him access to one milk laden breast. Peter began to suckle immediately and Pepper muted herself so Peter’s little snuffles would not filter through. Big or little Peter loved his feeds, especially when he was out of sorts like was with his siblings and Dad.
Pepper kept half an ear on the meeting while playing with Peter’s curls, helping him up when he was done his feed, winding him quickly.
Peter sat on his mom’s knees as she patted his back, wondering what he would do with the rest of his day while everyone was busy. He knew his dad would be back soon but he was bored now. As he let out a burp he caught something in the corner of his eye.
Loki was peeking in and gesturing for Peter to follow him. Glancing at his mom, he smiled at her. “I’m going to watch some TV and play with lego.” He said, giving her one last cuddle before getting up.
“Okay honey. I’m here if you need me. Do you want a paci?” She asked and Peter shook his head no. He was still big enough to not want it. “Okay, enjoy.”
Peter waved to her and tried to walk as if he wasn’t excited out to where Loki was waiting. When he got out of the room and closed the door he pounced on Loki. “Loki! You’re here!” He whisper shouted, Loki was one of his best little friends. “Are you big?” He asked, and really hoped he was.
“Uh-huh. Me and Daddy are here to visit Jane and Darcy. Daddy is gone down but I asked to play with you.” Loki said, hugging him back.
“Awesome! What will we play. My mom is in a meeting and Dad is dropping Harley and Morgan somewhere.” Peter said, no longer upset that his siblings and dad were gone.
Loki grinned at him then. “Want to play with magic?”
Peter gasped, Loki wasn’t supposed to use magic without Thor or dad around. “But Dad and Uncle Thor aren’t here?”
Loki shrugged, a mischievous sparkle coming into his eyes. “We’re both big so it’s okay. C’mon, let's go!”
He took Peter’s hand and took off down to Peter’s playroom. Peter trailing behind him in excitement. He knew he wasn’t supposed to do it but this was exciting, what was a little mischief anyway?
