Naked shenanigans
Peter slept on Tony’s lap the whole time he napped.
Pepper was busy getting everything ready for their trip to the park, getting all the food that they needed and Peter’s baby food that he liked to eat as well as his milk bottles because Tony found that his milk bottles were a great way to get him to calm down whenever he started crying a lot for no reason. He just put one of his bottles in his mouth and he calmed right down. Most of the time. The other times Peter refuses to drink out of his bottle and would fight Tony because of it but that was fine.
While Tony was busy holding Peter until his one hour nap was finished, Pepper decided to go and pack Peter’s diaper bag for Tony so that right after Peter wakes up they could immediately go to the park and didn’t have to wait around for Tony to pack anything else.
Pepper managed to get everything which was a lot of diapers because she knew just from being with Peter in his current state for a little bit that he needed a lot of diaper changes. She also packed wipes and creams as well as some change of clothes to change into just in case they needed to change his clothes for whatever reason.
“I think I got everything” Pepper said mostly to herself as she placed all the bags on the living carpet and put her hands on her hips to try and think if she was missing anything.
Tony looked at all the bags and didn’t think they needed that much stuff but then again they would probably realize they forgot something when they get to the park anyways so maybe that did seem like the reasonable amount of bags.
“Thanks for getting his stuff, Pep” Tony said gratefully. It would be a lot to try and pack Peter’s diaper bag while he was awake and wanting all of Tony’s attention. He decided that he could wake Peter up now because it was almost an hour for his nap and if he let him sleep then he wouldn’t be falling asleep tonight. “Hey, Pete, wake up, bud”
Tony brushed Peter’s soft baby curls from his forehead and pressed a kiss to him. After a few moments, Peter finally started to wake up and when his eyes landed on Tony he smiled immediately and reached his hands up for the man even though he was currently sitting on Tony’s lap to begin with.
“Daddy. Daddy” Peter said and stuck his thumb in his mouth. Tony let him continue sucking on his thumb but he didn’t actually know what age that stopped being acceptable at. Technically since Peter is actually fifteen years old it might not be acceptable anymore but right now he’s only two so he’ll let Peter continue sucking on his thumb right now. At the same time if Tony found his fifteen year old Peter sucking his thumb before all this happened he would probably tell him to remove his finger out of his mouth but thinking about if he found fifteen year old Peter sucking his thumb after all this happened, if they can get him back to a teen, he would probably be totally okay with it and let him continue to do it, he might even give him a pacifier if he wanted it but- no he can’t do that because that would be weird. Right?
Tony has no idea what life is gonna be like when Peter gets aged back up to a teen. Everything could go back to normal and Peter might not even remember everything that happened when he was a baby. Tony doubts that everything will go back to normal after this. He also doesn’t want Peter to forget what happened when he was a two year old. He wants Peter to remember everything and see how he cared for his kid and how attached Peter was to him.
There is also the chance that Peter will never go back to being a teen and will be stuck in his baby form forever.
Tony pushed those thoughts away for now because right now he wants to take Peter to the park with Pepper and enjoy their time together. “I’m gonna go change his diaper quickly and get him in some proper clothes before we leave”
Tony stood up with Peter in his arms and he felt his foot asleep and his butt numb from sitting for so long.
The things I do for you, kid.
Peter was getting fidgety and was kicking his legs to be put down so Tony quickly made his way to Peter’s bedroom and placed him down on the floor. “I wan’ down!”
Tony rolled his eyes because that’s exactly what he was doing but clearly he wasn’t doing it fast enough for Peter’s liking. “I am, Pete”
Once Peter was placed on the ground he ran over to his toys and sat down to start playing with them while Tony got his clean diaper and wipes ready. Tony decided that he would change Peter on the floor right now because he didn’t seem like he wanted to sit still.
“Daddy pway!” Peter geld out a teddy bear with a pink bow on top for him but Tony shook his head.
“No, Pete” He sat down on the floor so he could change Peter “We’re gonna go to the park today!”
Peter’s face immediately lit up and he stood on shaky legs and started bouncing up and down “Yay! Daddy pa’k!”
“Yeah, baby” Tony patted their ground in front of him for Peter to come and lie down so he could change him but Peter was too busy dancing “Let me change your dirty bum then we can go”
Peter stopped dancing and crossed his arms “Not di’ty!”
Tony laughed “It won’t be dirty if you let me change you. Come lie down”
Peter shook his head and stomped his foot and Tony had no idea why Peter was being so stubborn right now. He never really hated getting his diaper changed, sometimes he even liked it and kept bringing more diapers to Tony so he could keep changing him but right now he was being difficult.
Tony didn’t want to waste anymore time so he stood up and quickly grabbed Peter by the underarms so he could lie him down in front of him. Peter immediately started crying once he was placed in front of Tony and started kicking his legs.
“I’ll be done soon, buddy, but you’re making it harder” Tony managed to undo the diaper straps and pull the front down but Peter screamed and tried to move away so Tony grabbed his hips so he couldn’t move anymore.
“No! No! Don’ wan’ di’per change, daddy! Noooo!” Peter cried and continued to try and roll and kick away from Tony as he held him down and wiped the areas the needed wiping.
Thankfully it was only pee so it was a quick wipe. While Tony was busy getting the new diaper to change Peter into he got up and ran away into the living room where Pepper was.
Tony sighed and stood up with the clean diaper in his hand and grabbed the clothes that he was gonna dress Peter in so he didn’t have to come back into the room to get them and followed Peter into the living room where he found him trying to crawl under the table but no matter how small Peter was, he still didn’t fit so his butt was just sticking up in the air.
Pepper laughed at the scene going on in front of her and shared a look with Tony who just sighed then bent down and picked a screaming Peter up and laid him down on the couch so he could quickly get a diaper on him.
Tony got the dark blue jeans on Peter and a yellow teddy bear T-shirt on him followed by his socks and shoes. Peter calmed down almost immediately after Tony stopped manhandling him into a diaper and clothes which he was thankful for because he didn’t want a screaming Peter the whole day.
He picked Peter up in his arms and went to hold him on his hip but Peter wanted to walk so he whined and started squirming out of Tony’s hold to be put down so Tony let him and placed him back on the floor. Peter reached up for Tony’s large hand in his much smaller one and led him towards the elevator so they could leave.
Pepper helped grab the bags that had the food in it and the blankets while Tony grabbed the other bag and the diaper bag.
Peter babbled about something that Tony couldn’t understand the whole way down in the elevator but he nodded along to his kid anyways.
They got down to the garage and Tony helped Pepper load the bags up in the trunk then he picked Peter up to put him in his car seat. Once Peter saw where he was about to be placed he started kicking and screaming and fighting Tony which caused him to only hold onto Peter tighter so he didn’t fall.
“No! No, daddy! Noooo!” Peter whined. He did not want to sit in that stupid baby seat that was tight and uncomfortable and kept him away from daddy! No way!
“It’s only for the car ride to the park so you stay safe and then I’ll take you out and you can walk” Tony explained. He knew Peter hated his car seat so that was one thing he was excited about not having to use anymore when Peter ages back up. If he could find a way to do that.
Peter still kicked and screamed and demanded that Tony put him down but he didn’t listen. Tony continued to buckle him up in his car seat and make sure all his fingers and toes were in the car then he shut the door.
Tony has to admit that once the door was shut, it was a bit relaxing to be away from all the crying even if he could still hear it through the car but it wasn’t as loud and it was kinda nice.
Pepper noticed him standing by the driver's seat and not getting so she asked why “Everything okay?”
Tony nodded his head and gave her a smile, “Yeah, I’m fine”
And he was fine. He was more than fine because having Peter get de-aged was actually a really great experience that he was surprising enjoying and if things were coming to an end soon then he would miss doing all these things with Peter and he didn’t know what things would be the last time doing them.
He didn’t want his sink bath to be the first one and the last one but he didn’t know. If Peter got aged back up to his teen self tomorrow then the sink bath today would be the last one. Tony knew Peter wouldn’t fit in the whole sink as a teen and he’s pretty sure Peter wouldn’t want to be naked and squished into the sink while him and Pepper wash him and take pictures of him.
Tony turned around in the car to quickly glance at Peter but it was the wrong decision because as soon as the kid saw him he reached out for Tony to be held but Peter had to wait until they got to the park.
The whole car ride, which wasn’t that long, was spent with Peter screaming and crying for Tony while he tried to take off his clothes and buckles holding him into the car seat but he didn’t have much luck which only made Peter more annoyed.
By the time they arrived at the park, Tony had a headache and it looked like Pepper wanted to be anywhere but the park. Tony got out of the car which only caused Peter to scream louder because he probably thought that everyone was gonna leave him in the car while Tony and Pepper played in the park themselves.
“We’re here now so you can stop crying” Tony almost had to yell over Peter’s crying. Peter desperately reached for Tony while the man undid his car seat buckles. Once Peter was free, Tony places the crying toddler on his hip and went to help Pepper with the food and diaper bags. “I can carry that one too”
Pepper shook her head and grabbed the bag that Tony was trying to grab from her “You already have a very important load in your arms”
Tony looked at Peter who was now looking at the park with wide eyes but he thankfully stopped crying which was a relief. Peter had tear stains on his cheeks so Tony presses a kiss to his cheek which got a giggle out of Peter.
“Daddy no!” Peter giggled and tried to push Tony’s head away which only resulted in Tony trying to give Peter another kiss then another and another until Peter was giggling uncontrollably because Tony loved that sound and he never wanted it to stop.
“We can set up the blankets here” Pepper noted. “That way we can still play with him at the park and not have our stuff get stolen at the same time.”
Tony was barely listening to Pepper because he was more concerned on making Peter laugh again to hear his favourite sound that he was convinced had some magic to it.
“Wan’ go pway!” Peter pointed over to the park and tried to wiggle out of Tony’s arms so he could be placed on the ground and run off but Tony was not going to allow him to do that just yet. At least until they get set up.
“We’ll go play at the park soon, buddy.” Tony said. He bounced Peter on his hip which didn’t help at all. All it did was cause a loud whine to escape Peter’s mouth. “We just have to place our picnic down”
Pepper looked up at Tony and Peter sadly from where he was setting the bags of food up on the blanket. There was no need for them to sit here and watch her set up while they could be having fun and playing at the park. “I got this, Tony. Go play with Peter”
“Are you sure?”
Pepper smiled and waved them off as she heard Peter let out an excited giggle in response.
“Wan’ go slide!” Peter pointed to the slide and continued to wiggle out of Tony’s arms so Tony quickly checked around the park and the fields around the park to see if there was anyone sketchy looking around but thankfully there was no one aside from a little girl and her mother. The little girl must have been about six years old and swinging on the swings while her mom was sitting on the bench on her phone.
“Okay, let's go then” Tony places Peter on the sand and let Peter pull him by his hand over to the slides. Tony wasn’t sure he would be able to climb up on the play structure himself but he would let Peter go by himself and he would wait at the bottom of the slide.
Peter ran over to the stairs of the play structure and tried to climb them on the big side but he wasn’t able to with his height so he let out a frustrated noise and looked to Tony for help. “Daddy! Can’t- daddy!”
Tony laughed amusingly at his kid. Peter looked kinda funny trying and failing to get on the platform. Once Tony got to him, he lifted Peter up under his arms and placed him on his feet so he could continue to climb the rest of the way up to the top of the slide.
“Next time you have to climb from this side, Pete.” Tony explained, pointing to the much more accessible side for small people, such as Peter. “It’s a lot more easier”
“No! Daddy up!” Peter yelled. Tony didn’t know what Peter meant by that and apparently neither did Peter because he was changing the subject right after and demanding that Tony did something else for him now. “Daddy stand ‘dare!”
Peter pointed aggressively to the bottom of the slide which was exactly where Tony was standing so he didn’t know why Peter was yelling at him to stand there. “I am, bud. Slide down!”
Peter struggled to get into the proper position to actually sit down but I’m e he managed to do that he started to slide down. “Ahh! Daddy!”
Tony thought that Peter looked absolutely adorable sliding down the slide so when Peter reached the bottom he wasted no time in picking Peter up and throwing him into the air. “I got you, baby”
That caused Peter to let out a bunch of giggles so Tony kept doing it but quickly got tired of it so he stopped but Peter didn’t want him to stop. “‘Gin daddy! ‘Gin!”
“You have a whole park here to play in but you only want me to toss you in the air?” Tony joked. He didn’t actually mind tossing Peter into the air but he didn’t want to do that while they were at the park. They could do that at home.
“Slide ‘gin?” Peter asked. Tony placed him on the ground but he felt that Peter’s diaper was getting full so he would probably need to change it soon. By the looks of Peter crawling up the stairs and his diaper sagging between his legs, Tony decided that he should probably go change Peter right after he gets to the bottom of the slide. Tony just hopes his diaper doesn’t leak before then.
Peter slid down the slide again and once he reached the bottom Tony lifted him up in his arms and started carrying him away. Once Peter knew he wasn’t going back on the slide he started screaming and kicking.
“No! No! Slide ‘gin daddy!” Peter cried but Tony just patted him on the back as he continued to carry him over to where Pepper was sitting on the blanket.
“I just have to change your diaper and then we can go play again” Tony explained but Peter wasn’t listening or he didn’t hear because he was crying so loudly.
When they got back to the blanket, Pepper seemed to already know what the problem was since she was handing Tony a new diaper and wipes. “I can see his saggy butt from all the way over here”
Tony didn’t say anything as he sat down and laid Peter out in front of him but Peter tried to roll away to go play at the park again so Pepper had to hold his upper body still as Tony took off his shoes, pants and pulled the front part of his diaper off. “Ew. He did a poo. A big one”
“I can see that” Pepper looked at the diaper and tried not to gag because it was a big and smelly one.
“Can you Uh, can you get him some crackers to eat to distract him so I can change him without him kicking me” Tony asked. He held Peters legs apart so the kid didn’t get poop on his feet as Pepper handed Tony some baby crackers that Peter loved. “Look. Hmmm yummy, Pete. It’s for you”
Peter stopped screaming and kicking. He slowly held his hands out for the food so Tony handed them to Peter then got to work.
Tony didn’t mind changing Peter’s diapers when he let him. At times like this when Peter kicked and screamed and Tony had to bribe him with food to get him to stay still long enough for Tony to clean his butt, he didn’t like those diaper changes.
Peter continued to eat his crackers as Tony held his hands up with one hand while the other hand pulled the dirty diaper from under Peter’s butt and started to wipe him clean.
There was a tiny voice from behind Tony which startled him “He has a penis so he’s a boy”
Tony paused the butt wiping and turned around to see the same little girl from the swings as before. Tony had no idea what to say about that comment so he turned to Pepper who was trying not to laugh.
Usually Tony would have hid Peter’s private’s that were out in the open for everyone to see but the girl meant no harm and was a child so Tony didn’t feel the need to cover Peter’s boy penis up.
“He does in fact have a penis” Pepper tried to say seriously but laughed “He also needs his diaper changed so you should go back to your parents”
The little girl didn’t listen. She crouched down so that she could be closer to the diaper change. Peter looked over at her and Tony waited for him to start crying but he just held his hand out with an already chewed on a cracker for the girl. The girl made a disgusted face at what Tony thought was the cracker but then she plugged her nose and pointed to Peter’s butt.
“He has a smelly poo poo diaper” The little girl pointed out.
Both Tony and Pepper laughed but this time Tony said something “Yeah, it’s really smelly and that’s why I’m changing it for him so you should go back to your mom over there”
The girl ignored Tony again and then moved to be closer to Peter’s head. “He’s a cute baby. What’s his name? Mommy says she has a baby boy in her tummy”
“His name is Peter but you should go back to your mom now, kid” Tony tired again. He continued wiping Peter’s butt and around his penis and grabbed a new diaper, sliding it under his body and doing up the straps.
“Okay! Bye Peter! You’re a cute baby!” The little girl gently pat Peter on the top of his head and then ran back over to the park.
“She was so cute” Pepper said while she laughed. Tony laughed as well because that was so random.
Tony finished putting the diaper on Peter and then his shoes. He picked him up so he was on his feet “How about we go play on the slides again now?”
Peter squealed excitedly and grabbed Tony’s hand to bring him back to the slides. Pepper joined them for a bit but left so she could go back over to the blanket to get lunch ready while Tony stayed with Peter.
Just as Tony was about to bring Peter over to the blanket the little girl came running over to them excitedly “Peter! Can baby Peter play with me?”
Tony didn’t really know what to say to her because she wouldn’t hurt Peter but he didn’t want to leave Peter alone. “You can play with him until he has to eat his lunch in ten minutes, but you guys have to stay where I can see you, okay?”
The little girl nodded and happily took Peter’s hand in hers. Peter didn’t seem to mind either because he held on tight “Okay! I will because Peter’s only a baby so I have to take care of him”
Tony kneeled down to Peter’s level “I’m gonna be right over there with Pepper while you play with- what’s your name?”
“Allison!”
“-while you play with Allison” Tony ruffled Peter’s hair before standing up and walking over to Pepper.
He sat down and watched the two play. The little girl, Allison, was very gentle with Peter. She helped him climb the big side of the stairs and held his hand going down the slide. She also kept pulling Peter in for a hug which Tony thought was adorable. She is going to make an amazing big sister to her new little brother that is in her mom's tummy.
Tony took his eyes off of the two for a second and then he heard crying and Peter rushing off towards him with his arms out making grabby hands.
Once Peter made it to Tony’s arms, he picked his kid up and held him on his lap to try and calm him down. “What’s wrong, baby? What happened?”
“No bad!” Peter pointed to Allison who followed Peter over and had a guilty look on her face.
“What happened to Peter?” Pepper asked Allison.
“Um, I’m sorry! I-I just wanted to change his poo poo diaper like mommy said to do!” Allison then started crying and her mom must have heard so her mom walked up behind her.
“What’s going on over here?” Allison’s mom said sounding concerned and mad.
“I’m-I’m sorry mommy!” Allison cried “I just wanted to change baby Peter’s diaper because he has a penis and is a boy like the one in your tummy!”
Tony continued to rub Peter’s back but he kept moving around like he was uncomfortable. Peter cried harder and tugged on his diaper like he wanted it off immediately and that scared Tony because that little girl was talking about changing Peter’s diaper so what did she do?
Tony pulled Peter’s pants down to his ankles and stood him up the best he could so he could pull his diaper off as well, not even caring about ripping the diaper or the fact that it was in front of a strange woman that was now seeing Peter naked.
As soon as the diaper was off Peter a bunch of sand fell out of it. Tony checked his front and back to see if he was hurt or if there was any blood but there was nothing. Thank goodness.
“Allison!” The girls mom shouted “Did you put sand in his diaper?”
Allison cried louder and nodded her head. “O-only because I wanted to change his dirty diaper but it wasn’t d-dirty because his daddy already changed it!”
The mom looked between Tony and Pepper and then down at Peter sadly “I am so sorry for my daughter putting sand in your son's diaper. I’m pregnant with a boy so she’s always wanting to practice changing diapers so she can help when he gets here. I’m so sorry”
Tony didn’t answer the women, he was too busy holding his kid and trying to calm him down as well as try and brush most of the sand off his butt with his hand but he would most likely need to give Peter a bath to get it all off.
“It’s okay,” Pepper said “asides from putting sand in Peter’s diaper, she was very gentle with him and giving him hugs while they played so she’s going to make an amazing big sister”
“Thank you so much and again I’m so sorry about this” Her mom said gesturing to Peter’s sandy butt.
Allison stopped crying now as she looked at Peter sadly and tugged on her moms hand. “Mommy, can I say sorry to baby Peter? I didn’t mean to hurt him”
Tony tugged Peter’s pants and diaper fully off so he could put a new one on him. He wasn’t mad at Allison for doing what she did because she didn’t know any better but he just wanted it to be Peter, Pepper and him now.
“I don’t know, honey, you have to ask Peter’s mommy and daddy” Allison’s mom said. Tony looked up at her surprised because her saying that sounded… nice. Fitting. Peter’s mommy and daddy. Tony and Pepper.
“Peter’s daddy,” Allison asked Tony “can I hug baby Peter bye and say sorry for making him have a dirty diaper?”
“Um, yeah. Of course you can” Tony held Peter up a bit, now that he fully stopped crying, for Allison to hug him.
Allison got on her knees so she was more at Peter’s height but she was still a bit taller than him. “I’m sorry for putting sand in your diaper. I just wanted to make you clean again. Bye bye baby Peter”
“Bye bye!” Peter yelled excitedly and hugged Allison back the best he could when the girl hugged him.
Both the women cooed at the two children giving each other hugs, one of them naked with no pants on which Tony was a bit uncomfortable about but Peter didn’t have a care in the world about baring all and Tony knew that the women and the little girl where safe.
Allison and her mom then said their goodbyes and left the park.
“She was adorable” Pepper noted. Tony thought so too but he thought Peter was way more adorable.
“How about you get a new diaper on that sandy butt?” Tony asked Peter who just ignored him and started to run towards the park butt naked.
Tony sighed but it was more of a happy sigh rather than a mad, annoyed sigh. By now he was used to Peter’s naked shenanigans and he found them quite funny but in a way it also made him sad. Tony thought about if this could be his life now.
Maybe, just maybe he doesn’t find a way to turn Peter back into a teenager. Maybe this can actually be his life.
He didn’t think that would be so bad.
