Enjoy!~

"Mi'ser St'rk."

Tony was barely lucid as something or someone was prodding his cheek. He mumbled something, and then swatted at it before trying to fall asleep again.

"Mister Stark..." There it was again. He didn't open his eyes though. He just wanted to sleep, and maybe hang out with the kid later. Wait...

"Mister Stark!"

Tony shot up completely and yelped, almost falling off the couch. "Wha-What?!"

There was an, "Oof!" and then a groan. He looked down to see Peter on ground, rubbing the back of his head.

"Oh shi- kid, I'm so sorry," Tony exclaimed, scooping up the kid from the ground. "Are you okay? No injuries?" He asked, quickly scanning the small kid. Peter shook his head, "No, I'm fine. Just caught me off guard," Peter said, chuckling a bit.

"Kid, you're going to give me a heart attack," Tony deadpanned, rubbing his hand over his stubby face.

"Sorry," Peter chuckled again.

Tony sighed, but a smile formed on his lips. "At least I didn't squish you," He said, poking Peter's stomach.

"Yeah," Peter breathed. "I wouldn't survived how much you weigh."

"Oi! I'm not fat!"

"Kidding!"

Tony rolled his eyes. "Lets just make some breakfast, spiderbaby."

Peter huffed and crossed his arms. "I'm not a baby," he pouted.

He raised his brow at the small kid. "You sure about that?"

"Shut up!"

"Alright kid, you want some blueberry muffins?" Tony asked as they walked into the kitchen, putting the kid on the counter.

"You can cook?" Peter asked incredulously.

"Eh, sorta. I have my mom's cookbook," He replied, taking out a cookbook and opening the blueberry muffin recipe. He took out some ingredients and looked at Peter straight in the eye. "Don't go near the sink."

"Wouldn't dream of it," Peter mumbled, shuddering at the memory.

"Alright kid, why don't you get the ingredients from the cabinets? Considering how tiny you are, I'd figure you'd be good scouring inside."

Peter grinned and nodded. Tony led Peter up to the cabinets. He jumped inside the cabinets and looked around. The cabinets were full of spices and other food stuff, it was almost overwhelming on how much spices were here.

"You alright, buddy?" Tony asked when Peter sneezed.

He heard a small sniffle and a squeaky voice. "Yeah! Its just that-do you ever clean up here? Its so dusty here!"

"Well, I didn't expect to be slammed by how my cabinets are," Tony joked, earning a giggle from Peter up above. "Okay kid, enough talking. I don't want a cranky teenager not getting his food in his tiny stomach. Can you get the salt?"

"You don't bother to just keep it on the table?" Peter's voice echoed.

Tony snorted, "I would, but I'm too lazy."

He could mentally see Peter rolling his eyes.

There was a bit of shuffling.

"Found it! Heads up!" Peter yelled, pushing the salt out and then dropping it out. Tony caught it with one hand without looking and grinned. "Nice job, kiddo. Another thing we need up there is the vanilla extract."

"Okay, give me a few moments."

While Peter was doing his own searching, Tony went into the fridge and brought out the blueberries, milk, eggs and other ingredients from the fridge. He knew he needed to get the heavier stuff from the cabinets, but he wanted the kid to be part of the baking.

A identical voice above called him. "I have it, Mister Stark! You ready to catch it?"

"Yep! Throw away," Tony said, holding out his hand. The object fell and Tony caught it. He looked up and saw Peter poking his head out with a lopsided smile. "Anything else?" Peter asked.

Tony looked at the cookbook and nodded. "We just need baking powder? You think you can get it?"

A short determined nod and Peter was gone.

The billionaire got everything they needed to get the cooking started. All he needed was the baking power and Peter-

"Got the baking powder, Mister Stark!" Right on time.

Peter threw the last object and Tony caught it (As always) and placed it down on the counter, along with the other ingredients. "Thanks Pete, think you could jump down and let me catch you?" Tony asked.

The boy was a bit hesitant. "Promise you'll catch me?" He asked, biting his lip.

"Promise, kiddo. I would never let you fall," Tony said sincerely.

There was something fuzzy in that saying for Peter. It was like Tony was his net.

Taking a big leap of faith, he jumped out, watching Mister Stark's eyes watching him intensely. And then he knew that Tony would catch him.

He landed on Tony's palm and took a breath of relief. Tony was doing the same. Thank God he caught him.

"Alright kiddo, let's say we make the muffins?"

Peter smiled.

"Seriously, Pete? I told you not to stand on the rim of the bowl!" Tony exasperated. Clocking backwards, while Tony was pouring the batter into the pan, Peter decided to climb on top of the bowl. When he got there, everything was fine, until the wooden spoon hit the side of the bowl, making it rattle.

Peter felt like it was a earthquake, and before he knew it, he was swimming in the thick batter. He was lucky enough that Mister Stark didn't add the large blueberries in yet. Now, Tony was filling a bowl of warm water and grabbing the back of Peter's clothes.

The boy sighed in content when his feet touched the warm water and then being placed fully in the water.

The water immediately turned a murky of muffin batter.

"It worked out for a little while," Peter said quietly, splashing the water to his face.

Tony rolled his eyes and dumped the rest of the batter in the sink. "You're lucky that I have already poured the muffins in the pan," he grumbled.

Peter giggled and shrugged. "At least I didn't drown."

"Damn right you didn't," Tony breathed.

After Peter was done cleaning himself, (With Tony turned around and looking everywhere else but the bowl) Tony threw a small towel that floated down on Peter. The boy accepted it and wrapped himself inside the warm towel.

Tony still needed to watch the muffins, so he quickly went into his bedroom, unplugging his blow dryer and rushing back to the kitchen. Seeing Peter was still poised where he was, he plugged in the blow dryer and turned it on low.

"Thanks, Mister Stark," Peter smiled, and poked his head out of his cocoon. He felt the the gentle, warm breeze hitting his wet face.

Tony smiled. "No problem, kiddo. Just get warm and then we can have some muffins."

Peter hummed.

The muffins were out and cooling on the rack and Peter was luckily dry. Though, Peter was still in front of the blow dryer, content where he was. Tony was just tempted to make a human sized blow dryer for Peter when he returns to normal.

"Enjoying yourself, kid?" Tony chuckled, resting his head on his arms and looking at the tiny Peter.

"Yeah, its warm and cozy," Peter murmured, eyes meeting Tony's large ones.

"Not like my 'squishy' stomach" Tony raised a brow.

Peter groaned and hid his face behind his hands. "You're never gonna let that go," he mumbled, earning a huffed laugh from Mister Stark.

"Nope."

"Knew it."

"Quiet you," Tony smiled and took placed a cool muffin besides Peter. "Now enjoy your blueberry muffin. Fresh from the oven and made from love."

"More like me," Peter joked.

"You immediately made me lost my appetite," Tony faked his disgust, but was smirking.

Peter stuck out his tongue and took a crumb from the muffin. His eyes widened with delight. "This is so good, Mis'er Stark!"

"I'm glad you think so," Tony took a bite out of his own muffin.

After a few moments of silence, Peter swallowed the last of his small portion of food and sighed in satisfactory. He looked up at Tony who was staring at his bitten muffin. Peter furrowed his brows, "Are you okay, Mister Stark?" he asked.

Tony came back from his thoughts and realized that he was just staring at his half eaten muffin. He looked at Peter and nodded.

"Yeah, just thinking about my mom," Tony said quietly, allowing the nostalgic memories flit through his mind like a book. Peter made a noise of understandment and looked down.

"What was she like?" Peter asked suddenly, not bothering to look up.

Tony looked taken back, and he stood like that in silence for what felt like forever.

"She...was amazing," Tony started, looking at Peter who suddenly looked up at him in shock. He gave a shaky sigh, "She always made me muffins like these for breakfast. Sang some Italian songs too." He chuckled, "Its one of those memories I have with her."

Quietness filled the room.

"That sounds like a lovely memory," Peter said, a small smile graced his lips.

Tony nodded and grinned at Peter, "Yeah, it was."

Once they were done with breakfast, Tony decided to head down to the lab, with heavy supervision of course.

"Make sure you don't blow yourself up. I don't want to be killed by your hot aunt," Tony said.

Peter made a salute. "I won't let you down, sir!"

"God, sir is worse than Mister Stark," Tony joked, earning a roll eye from Peter. They arrived to the lab and Tony placed Tiny Peter on the lab table and turned around for a second. Peter didn't move whatsoever.

Tony returned with a piece of paper and a pen still larger than Peter.

He placed them next to Peter who looked at him curiously.

"You can work on the recipe for your spider webs. I know you want to work hand on hands, but I really don't want you to injure yourself," Tony said, biting his lip. He expected Peter to be upset, but instead Peter just nodded and picked up the large pen.

"Don't worry, Mister Stark, Its okay. I kinda don't wanna destroy myself either."

Tony nodded. "Good. My back will be turned towards you, but I won't be to far if you need me, alright?" Peter hummed and nodded, writing something on the piece of paper already.

He turned around and worked started working.

Eventually, the silence was too much.

"Hey, Pete?"

Peter looked up from his paper.

"Mind if I turned on some music? Its not going to overload your sensors when you tiny?"

Peter shook his head and smiled. "Nope! Fire away."

The music turned on and they worked on their stuff. Occasionally, Tony would take a peak at Peter just to make sure he was alright and he wasn't doing anything stupid.

Somehow, Tony fell asleep. He never fell asleep, but apparently it happened. It was rare.

Peter never noticed it. He was too engrossed in upgrading the spider web fluid. The pen was pretty large and sometimes it would tilt. It was kinda hard to control the pen, but at least it worked in his favor.

He laid the pen on the floor and stretched his limbs, yawning.

"Hey Mister Stark?" Peter asked, turning his head. Tony's body was still.

"Hello?!" Peter yelled, but his voiced underuled over the music.

No movement.

"Seriously? I never seen you fall asleep in the lab," Peter deadpanned, running his hand through his hair. Seeing that he was stuck here, he was about to pick up the pen, until he heard skitters of something.

"Huh?" He turned around to the sound.

A shadow of something hurried onto the lab table. Peter squinted and then his eyes widened in surprise and maybe fear.

Spider.

The spider was almost as large at Peter, but all the spider knew...is that he was food.

"Hey there friend," Peter trembled, backing away very slowly. "Think we could have a spider to spider kind of moment? And by that, not eat me?"

He prayed that the spider understood, but it kept walking slowly to its prey.

"Is that a no?" Peter asked, eyes widening like a light bulb.

The spider hissed and lunged at him. Peter's mind raced and the only idea he could think up...was jump. And he did. Peter landed on the ground with a loud thud, and groaned.

He looked at his mentor's form and nothing was moving. Well...looks like he was on his own.

Peter stood and ran for his life. Still praying that Tony or something would find him, the spider glided down and scurried across the room to Peter. He was able to look back quickly and turn pale to see the spider running at him.

Now he wished he had eight legs.

"Look buddy," Peter said breathlessly, "I would love to be your friend? You want friends? We can be friends! Just don't eat me!"

He continued running, even though it wasn't a big distance for normal sized people.

What felt like minutes, he found a hiding spot for now, near a box full of parts. He breathed heavily, catching his breath. He stayed silent for a few minutes, using his hearing for any skitters or hissing.

He didn't know Spiders could hiss.

Peter didn't hear any and when it was coastal clear, he licked his lips.

"Friday? Can you hear me?"

"Yes I can, Peter."

Peter was beyond relieved. "Great, please wake up Mister Stark."

Suddenly it went silent, until an ear shrieking noise came from above, startling not only Tony, but Peter as well. It vibrated his whole body, like his insides were blending together. He whimpered, knees collapsing and hands on his ears, as if it would calm his senses. Everything was hurting.

Finding himself on the floor, he curled up and waited for the pounding ache to go away. Peter thought it was an overload sensory, but it felt unbelievable worse than that. Probably because he was so small and his body couldn't handle the extreme sounds of everything shaking.

It hurt so bad.

Tony shot up and bleary looked around, completely unfazed about what was going on.

He grumbled. "Friday, turn that off."

The screeching sound ended and then a robotic voice chipped in with what felt like a concerned voice. "I apologize, sir, but Peter asked me to wake you up."

His eyes were wide open and functioning on hearing Peter's name. "What do you mean, Fri?" Tony asked, about to turn around to face where Peter was. "He's right here-" he stopped dead in his tracks.

His pen was there and the piece of paper, but no Peter.

"What the hell?! Where is he?!" Tony yelled, completely shoving things out of the way to look for Peter.

"Sir, there was a spider in here and-"

"I don't get spiders in my lab, Fri. There has got to be another reason," He said between breaths. The AI was silent, until a hologram of a spiderweb in the far right corner on the ceiling. He honestly didn't have time for this, but he obeyed and looked.

"Odd," Tony murmured, but still rummaging his hands around the stuff, hoping to find Peter without even looking. "That's not the spider's doing...thats Peter's web!"

"It seems to have made a home to Peter's spider webs. And because of the formula, it lasted longer than it should have," Friday explained.

He shook his head frantically, "We can talk about this later, where is Peter?!"

"He is behind the box to your left. Tread carefully though, he experiencing high sensory load because how miniature he is. His brain cannot process the pressure.

"Got it, Fri, thanks."

Tony rushed to the box and scooted it carefully out of the way. He heard a whimper when the box made a shuffling sound. Tony froze. "Kiddo?" He whispered.

Another whimper.

"Come on, kid. I need to move this box and I can help you, alright?" He got another whimper and Tony's heart was just about to break at the sound. Wanting to get this over with, he shoved the box away, earning a pained shout from the tiny Peter.

Tony saw him curled up, his face pale and drenched with sweat as he could see the kid's hands covering his ears and eyes clenched tightly closed.

"Oh, kid," Tony murmured, gently kneeling down and ignoring his legs protests as his bones cracked slightly.

The kid held up his hands when Tony was about to pick him up.

"N-no! P-please. I-it hurts! I-I can't- It hurts!" Peter cried out, crumbling onto the cold floor again.

Tony was about to cry with him when he saw Peter having tears running down like a waterfall. He almost felt the pain when Parents see their children in distress. "What hurts, kiddo? Talk to me," He gently whispered.

"E-everything. M-my ears, and eyes and-and-" A gut wrenching sob tore through his tiny throat.

"Shh, kiddo. Just take deep breaths. Your not experiencing just sensory overload, but panic attacks. Shh." Tony couldn't do anything without hurting the kid, but it pained him to see his kid in such...agony.

Peter took a big gulp of air and mewled when the air hit his raw mouth and lungs.

"Its okay, just deep breaths," Tony said, eyes never leaving Peter's small form.

Eventually, when Peter seemed to have calmed down a bit, Tony vaguely remembered that babies enjoy hearing their parents heartbeats, so maybe...?

"Can-can I lift you up? Maybe we can try something that will calm you," Tony said, a bit reluctant.

A small nod and then a groan.

Tony, ever so calmly and gently, scooped tiny Peter into his palm, his hands being so steady. He moved his hands to his chest, where he cupped one of his hand to accommodate Peter, and the other drooping to his side. It was like he was holding a baby. He straightened, giving his knees a break.

Peter was just above his arc reactor, humming and glowing brightly under his dirty shirt.

The boy still had his eyes closed, but could faintly hear the humming. Peter instantly calmed, his whole demeanor changed and relaxed. The humming soothed him just like that and Tony was beyond surprised, but if it meant that the kid was calming down, he'd do anything.

"There we go," Tony whispered, slightly rocking back and forth. The kid's fingers weren't clenching into his palm, but more at Tony's shirt.

"When did I get so freaking paternal," Tony asked no one, looking up at the ceiling. And when did Peter become a baby?

A voice startled him though.

"Because your my dad," Peter faintly answered, though not very coherent.

The billionaire blinked. Him? Dad? Peter? What? Tony allowed himself to smile a bit. Maybe being a dad wouldn't be so bad. If Peter was in this, then why the hell not? Tony wasn't even going to ask Peter, because the kid was out like the wind.

It took every ounce for him not to hug Peter. After everything he went through and now being shrunk with experiencing sensory overload, as well as panic attacks, Tony felt like his kid deserved it...

And once Peter is back to his regular size, he was going to hug him, play with his hair and do whatever the kid wanted.

Because apparently...he was a dad.

Peter woke up with a groan, turning his head towards something...

Squishy? Soft?

Peter sniffled.

Motor oil? Cologne?

Wait.

Peter eyes shot open, but instantly regretted it when his head pounded. He groaned once again and laid his arm across his face, swallowing the nausea feeling in his stomach.

"Well, look who decided to wake up." A voice Peter instantly recognized.

"Hello, Sunshine," Tony smiled.

"Shaddup," Peter murmured, nuzzling his face into the billionaire's shirt.

Tony gasped, making him jolt. "I'm hurt, Peter. After everything I've done for you," he said dramatically.

"Yeah, like using your stomach as a squishy pillow," Peter murmured, inhaling the reassuring cologne and oil from his mentor's shirt. The billionaire sighed, but chuckled afterwards when Peter went totally quiet.

"Y'know, I feel like I need to say this right now," Tony breathed. "Are you okay?"

Peter blinked up at him and nodded. "Yeah, just...got overwhelming."

Tony nodded sadly, "Do you remember anything else during that? Like when I picked up up and all that jazz?" he asked, looking at tiny Peter intently. The boy thought for a moment before his eyes widened as big as a penny.

"You-I...I called you dad?"

Tony nodded.

"Oh my gosh, Mister Stark, I'm so sorry, I didn't mean any of this!-"

"Pete, Pete, slow your roll. I'm not mad," Tony stated, his face unreadable. Peter looked at him fretfully. "Your not?"

He shook his head and grinned, "No, I thought it was pretty cute," A groan escaped the boy's tiny mouth. "You don't have to feel embarrassed about it, buddy. In a way, I guess I do act like a dad to you sometimes." Tony admitted quietly.

Peter was silent, but he smiled and chuckled, "Yeah...well, thanks for not letting me do stupid stuff. I owe it to you."

The billionaire returned the smile and nudged Peter's head just a bit. "No problem, kiddo. That's what fathers supposed to do," he replied. If only Tony could take a picture of Peter's expression, he would've framed that above his lab table.

While Tony was thinking of the possibilities, Peter was smiling absentmindedly. He looked up at his mentor, "Hey, Tony?"

Tony couldn't conceal his smile when Peter used his first name. He said it times before, but he was actually safe, calm and not drowning in water or batter, or being chased by a damn spider.

"Yes, Peter?"

"Thanks...for taking care of me. You really didn't have to do it, but you put up with me and-yeah...thanks," Peter mumbled.

The billionaire smiled. God, I love this kid so much.

"Any time, kiddo. Next time, lets stay on the couch."

Peter laughed and nodded. "Wouldn't have it any other way."

A week later and everything was reversed. Eventually, Peter and Scott got the device working and thank God, there won't be any accidents. (Hopefully.)

Scott said that the device malfunctioned and it was completely fried. Luckily, Hope and her father got it fixed...after they lectured him for being stupid and using a test subject. Like himself. And Scott couldn't agree any more. At least he knew his way around the place when he shrunk.

But Peter was going to learn. The device was literally on his suit and it could come in handy soon.

Peter was back to normal, and it was all good. Though, he hasn't seen Mister- I mean, Tony since then. When Peter was reversed, he had go straight home. Eventually, May knew and surprisingly, she wasn't as pissed.

But, she did want the footage of tiny Peter Parker falling into the batter and then being chased by a spider. Oh, how he loved his Aunt May.

Peter walked into the penthouse with a wide grin, feeling completely energized and...normal. He forgot how much he missed having his height and not falling into the sink or batter.

It was good.

"Hello, Peter. How are you doing?" Friday's voice chipped in.

"Good, Fri! Thanks! Do you know where Mist- Tony is?"

"He was in the lab, but now he's coming up to greet you," Friday answered. Peter nodded, and headed to the couch, plopping his backpack on the floor and then throwing himself on the couch.

His face squished by the soft mattress, content.

Until he felt someone flicked his head, making him alerted. He shot up, trying to act professional, but he fell of off with a yelp. Groaning, there was a loud laugh coming from behind the couch.

"Why?" Peter mumbled, standing up and brushing away something on his shirt.

Tony chuckled, his StarkPad under his armpits and looking as disheveled as always. "This is payback for giving me a heart attack multiple times last week. And since I couldn't flick you when you were miniature, now is a great time."

"Child abuse..." Peter muttered.

"Heart breaker," Tony shot back, grinning ear to ear.

"Shut up."

"Oi, respect your father."

Peter's ears turned red, remembering the memory.

Tony chuckled at the kid's embarrassment, and decided to ruffle his hair up. I missed his hair so much.

"Don't be like that, kiddo. I'm glad i'm your pseudo-dad. Its an honor."

"Yeah," Peter smiled a little. "I'm glad I'm your pseudo-son," he joked.

Your more than that, kid.

"Alright, kiddo. C'mere." Tony placed the StarkPad on the couch and spread his arms wide, welcoming the spider. Peter's eyes widened, but when Tony looked at him with a -what-are-you-doing-im-giving-you-a-hug- look, Peter lunged at his mentor.

Tony grunted, but wrapped his arms around the kid.

"Your the best, Tony," Peter says and Tony was just tempted to ask the kid's aunt if he could adopt this precious kid he's grown so attached too. They stayed like that for about 3 minutes, hugging and Tony playing his curly hair.

"Hey kid?"

A hum.

"Your the best kid I could ever ask for. You think your hot Aunt May would let me adopt you?" Tony was half joking, but the last part was pretty serious. They could co-parent Peter, even though he felt like he was doing the co-parenting forever.

Maybe they could...

Peter snorted, "Good luck." A beat. "I think Aunt May would approve."

Tony smiled.

This kid.
