"Oh Don!~ I need help with the tv, I think it's broken!"

"Not again, Mikey.. This is the fifth time this week!" The purple-themed turtle sighed, standing up from his desk and walking over to where his brother sat, hand stabilizing his crossbody bag as he jumped down from the platform.

"Let me see what the problem is.." He moved to the back of the many television sets, checking outlets and wires for any disconnections or fraying parts. His eyes narrowed, following a wire to its respective tv, and paused, confused when nothing seemed to be wrong.

"Hmm, I'm not seeing any issues.." he walked back around to where the youngest was, startling as he saw Raph there was well, arms crossed as he looked at the blank screens. "O-Oh, Raph! When did you get there?.."

The elder shrugged. "Heard Mikey over here complainin' 'bout the tvs not workin'." He tilted his head, running a finger along the top of one of the screens. "Thought ya fixed them the other day.." Donny sighed, nodding. "At least I thought I did. Apparently, they keep breaking. I just don't know what's wrong with them."

A whine was heard from the orange-clad. "Are you saying you can't fix it? Donnn, I need tv!"

"Shaddup, Mike. He hears ya.." the sai-user hushed, turning back to his more reserved brother. "Surprised to hear even the all-time genius is havin' a tough time. Too much stress, Don?" the elder teased, but the last sentence has a tone of concern to it. Donatello's cheeks went pink, and he began fiddling with his fingers. "Uhm, I don't know.. Everything's going just fine, so-"

"You sure, bro? You look a little flushed."

The olive-toned mutant stuttered a little. He always did get nervous rather easily.. Mikey scooted over to his genius brother, hands clasped together as he stared up at him with puppy-dog eyes. "Pleeease fix the tv! I'm begging you!"

"O-Okay, Mikey. Stop that, I'm doing my best." The youngest latched onto his leg, clinging tightly onto the limb, leaving Donny to try and step away, unable to do so with the new weight. The nunchuck-user nuzzled into his thigh, still babbling out pleas to have the television fixed. At the contact, the scientist's mouth pulled into a smile, pushing gently at the younger's head.

"Ah! No, thahat- tihicklehes!"

"Please fix it!"

At that instant, Donny crumpled to the ground, still trying to get his brother off of him. "Ooh, you'd better listen to him, Don. He sounds serious."

Mikey didn't let go, pressing his face into the other's knee instead. Donny yelped, kicking out at the feeling. "Wahait! Dohon't, I- Hehey!" Raph had sat behind the purple-themed turtle, snatching his arms up and pulling them above his head. "Get 'im, Mike. I don't think he's listenin' to ya."

Mikey giggled, letting go of the older's leg, only to sit on his waist and poke at his torso. "Pay attention, Donnyyy!" The turtle scrunched his nose up, giggles interrupting his words. "Rahaph, don't emcourahage hihim! Ahah!"

"Encourage what? I'm helpin' ya with yer listenin' skills." The elder of the three teased, leaning into his brother's ear, making him squeak and scrunch his shoulders up a bit. "Noho, you're nohot!"

"Oh, so now I'ma liar. Don't be so rude, Don." The elder darted his arm down, now only using one hand to hold up his brother's, squeezing at the side of his neck. The bo-staff-user squealed, throwing his head to the side and flailing about.

"Hahah! NO- I dihiHIdn't sahay tHAHAT!" He squawked as the youngest began kneading his ribs, twisting and turning to try and fight the ticklish sensation. "Yeah? Then what did ya say?"

Donny's brain was frazzled, the buzzing feeling at his neck and ribs were mixing up his thoughts. He couldn't even remember what he said! "IHI- I fohorgot! Stohop it!" His entire face was dusted a shade of pink, eyes closing at the intimidating sound of his brother's voice.

"That's what I thought."

There was a moment of dead silence, both turtle's hands stopping, before Don saw Mikey share a look with the other. Before he could even utter out an apology, four hands were drilling into his sides. It took only a split second for his now free hands to dart down, but it made no difference to the ticklish agony he was plunged into.

"HAHAHAH! GUHUYS,- SNRK- STOHOHOP! HAAH!"

A loud snort escaped from his mouth, making the youngest snicker as he continued wiggling his fingers into the squishy flesh of his sides, unprotected by a shell. "Gee, Don. Think ya can fix the tv now? I wanna watch some shows with Mikey ov'a here."

The scientist stomped his feet on the hard ground, elbows trying to press down over his sibling's hands to cover himself, but the tickling didn't stop. "YEHEHES! YEHES, IHI'LL TRY TO-HAHA! IHI'LL TRY!"

Mikey groaned, blowing a raspberry in the middle of the elder's plastron. "I don't want you to try, I want the it to work!" Donny squealed during the entirety of the raspberry, curling in on himself and bucking frantically until it was over.

"OHOHOKAHAY! OKAYOKAY! IHI'LL FIHIX IT!"

That got the youngest to stop, but Raph only shot his hands up, squeezing the muscle in the back of his armpits. Donny screeched, face bright red as he laughed, arms slamming down, only trapping the ticklish feeling. "RAHAHAPH!"

"Alright, fine.." The red-themed mutant slipped his hands out of his brother's underarms, hoisting him up into his lap with a bear hug. "C'mere, brainiac.."

Don slumped into the hold, panting slightly as he caught his breath. He moved his head to the side, pushing Mikey away with his foot when he tried to grab onto his leg again. Instead, the nunchuck-user knee-walked around him, and sat next to Raph, who pulled him into the hug as well.

The three smiled, peacefully sitting together for a moment, until Mikey checked the time.

"My show is on in ten minutes!"

“No! No! No! No!” The little version of Donnie yelled as his younger twin carried him under his arm. Well, I guess he was the younger one now. Physically that is. An experiment gone wrong had changed Donnie back into a small kid. He was still teenage Donnie, but his form was that of when he was around six years old. And now he was forced to go towards Raph’s room as Leo held onto his squirming figure.

“Oho no, Donton. I know for a fact Raph would love to see this.” Leo chuckled in a playful tone. Donnie continued to kick his little legs and try to escape. The sleeves of his hoodie, slightly longer than his arms, flapped along with his hands with each desperate attempt of freedom.

Leo shushed Donnie then knocked on Raph’s door, hiding Donnie behind his back. He walked in after hearing a “come on in.”

“You’ll never guess what I found dear hermano.” Leo smirked, making sure to keep a good grip on the still squirming Donnie against the back of his shell. Before Raph could guess, he heard a small grunt from behind Leo. “Uhh, Leo…” Raph stood up from his bed. “Please don’t tell me you stole a kid-“

“Why would I- Never mind. Look!” He exclaimed bringing Donnie out from behind his shell and holding him up for Raph to see. Raph gasped, only to then aww at his adorable little brother.

“Daww!! Look at little Donnie!” Raph gave Donnie a pat to the head. Donnie swatted at his hand before giving up and accepting the affection. “But wait, how did this happen? Leo, you didn’t do this to him did you?!” Raph pointed a stern finger at him.

“It wasn’t me! Little Donnie here was experimenting on himself again.” Donnie tried to protest, but Raph was way ahead of him. “You what?! Donnie, I thought we talked about this. This is extremely dangerous. You’re lucky you didn’t turn yourself into some other mutant thing. We don’t need to be more mutated than we already are.” Donnie huffed and crossed his arms.

“Oh relax! I didn’t die or anything. Now if you let me go, I can go reverse this and we can pretend this never happened.” Donnie tried to sound serious with his kid voice. It didn’t work. If anything, it made his brothers smile even more.

“Not gonna happen.” Raph started. “You need to learn to be more careful. Even though this experiment seems to be the most adorable mistake you’ve ever made.” Raph’s baby voice came out in the last sentence as his pupils grew three times in size. Leo nodded his head at Raph’s comment.

“I know right!! He’s just a little guy!” Leo nuzzled his cheek against Donnie’s. Donnie pushed at his brothers face, his legs trying as hard as they could to kick at Leo’s arms. “I am not adorable now put me down!!” Donnie yelled. He yelped when Raph took him from Leo. Leo pouted, but remained where he was, letting Raph have some time to reminisce about when they were little. Raph held Donnie in one arm, the other flapping in happiness.

“I REMEMBER WHEN YOU GUYS WERE THIS SMALL!! I wish you guys could’ve stayed like this forever!” Raph couldn’t help the tiny jumps on his heals. He was having cuteness overload and Donnie would be lying if he said he didn’t find Raph’s reaction to him a little adorable. It was still embarrassing nonetheless, but seeing his brother so happy over his mistake was better than anger. A smile crept its way onto his face when Raph lifted him up and spun around a little. Leo wished he could take pictures with his mind, he had unfortunately left his phone in his room.

“Hey, I heard Raph’s cuteness overload voice what am I missing?” Mikey said as he suddenly entered Raph’s room. He immediately eyed the tiny version of their brother in Raph’s arms.

“OH MI GOSH!!!!” Mikey exclaimed, quickly snatching little Donnie from Raph. “Aren’t you just the cutest little thing!” Mikey cooed as he hugged him close. His brother was just too cute! And the oversized hoodie and glasses weren’t helping Donnie’s case.

“I am not cute!! Now put me dohohown! Hehehehe! Mihihikey!” Donnie burst into squeaky giggles when Mikey started to prod at his neck. His shoulders scrunched up with each feather light poke.

“Oh my gosh- I think my heart is going to explode-“ Leo held a hand against his heart as he stared at the adorable sight. At the same time, Raph brought out his phone to take a video. Mikey moved from one side of Donnie’s neck to the other, Donnie’s small fingers only managing to lightly push at Mikey’s hand.

“Nohohoho! Stahahahahap! Hehehahaha!” Donnie squealed when the back of his neck was targeted. Mikey felt his heart absolutely melt. And that’s when Leo thought of a plan. A plan to make sure Donnie wouldn’t make this mistake again.

“Ohokay. Mikey will let you go…” Leo paused for dramatic effect while leaning down towards Donnie. “If you promise to never experiment on yourself again.” Donnie gasped through a giggle.

“Nehever! I aham a mahahan of sciehehehence!” Donnie managed to say as Mikey continued his light flutters to the back of Donnie’s neck. Leo smirked, knowing that was exactly the answer he was going to get.

“Well right now you’re a man, or boy I should say, who’s gonna get tickled until he agrees with us.” Donnie’s eyes widened. They wouldn’t- not while he’s like this- Oh who was he kidding. Of course they would!

“Noho wahahahay!” Donnie could never ignore the sweet call of the mistress that is science. Even if it did mean getting tickled to death while being in this form.

“I was hoping you’d say that hermanito.” Cue Leo’s classic smirk before he joined Mikey in tickling Donnie. Raph stood to the side, recording video after video and trying to keep his cooing quiet. Donnie’s laughter was proving to be loud enough to cover any comments he made anyway.

“Aww~ Does that tickle, Tinytello~” Leo teased, scribbling his fingers around and around Donnie’s little plastron. He made sure to give pokes to his sides every now and then to hear little Donnie’s voice crack with each squeal.

“Nahahahahahaha! *squeal* Stahahahahahap!” Donnie kicked his legs and switched between trying to grab at Mikey’s fingers and pushing at Leo’s hands. Neither was doing much for his benefit. His glasses were a bit askew on his face and the hoodie was doing little to nothing to protecting his sensitive shell.

“Rahahahahaph! Hehehelp mehehe!” Donnie tried reaching out towards his older brother, only for a sneaky finger to wiggle under his arm causing him to shriek and pull back.

Leheohoho! Knohohohck ihit ohohoff!” Donnie yelped as Leo’s finger remained “trapped” under the little turtle’s arm. Raph giggled before deciding it was time to join in on the fun. He set up his phone against some clutter on his shelf, making sure he was able to get everyone in the shot. He walked over to stand beside Mikey and grabbed onto the tops of little Donnie’s knees.

“NOHO! Rahahaph dohohohon’t!” Donnie was still trying to keep his other two brothers at bay. He knew he would give in eventually if Raph contributed to the antics. Mikey and Donnie paused their assault, giving him time to take a break.

“So Tinytello~” Leo bent down to gently talk into Donnie’s ear, knowing it was a sensitive place for Donnie. “Are you gonna stop being a menace to yourself? Or are you gonna die of adorable squeaky giggles. Your choice.” Leo chuckled at the way Donnie shook his head but couldn’t help but giggle at the whispers.

“Leo’s right, Donnie. If you don’t agree, we’ll just have to keep you like this forever and ever. Tickling you aaaallll night long.” Mikey punctuated his sentence with some squeezes to the back of Donnie’s neck. Donnie snorted and curled up best he could, unable to make any sort of comeback.

“And then we’ll have to tell April. And I’m sure she’d loooove to tickle little Donnie until she feels satisfied.” Raph started squeezing Donnie’s knees. A high pitched squeal followed by louder giggles filled the room. Leo lifted Donnie’s arm that was closest to him and slowly wiggled his finger towards the outstretched underarm. He snickered at how Donnie barely even tried to pull at his arm, accepting his fate and giggling his little heart out.

“All together hermanos!” Leo declared, his finger finally touching its target and wiggling away under Donnie’s arm. Donnie kicked and squealed and snorted and swore. His other arm flapping due to happy stimming and not really knowing what else to do. Mikey gave Donnie a big raspberry to the side of his neck and that’s when he finally brought out the white flag to wave in surrender.

“OKAY! OKAHAHAHAY! I GIHIHIHIVE! I WOHON’T- GAHAHAHAHAHA STAHAHAHAP!” Donnie lost himself in laughter when Raph interrupted him by quickly lifting up his hoodie and blowing a raspberry on his plastron.

“Sorry what was that? Didn’t quite hear ya.” Raph teased, blowing another small raspberry on his side. Leo continued to hold onto Donnie’s arm, the other lightly smacking at Raph’s head with the hoodie sleeve.

“I WOHOHON’T EHEXPERIMENT OHON MYSEHEHELF! NOHOHOW STAHAHAHAHAP! PLEHEHEHEASE!” Raph and Leo finally backed away. Mikey letting Donnie go limp in his arms, cradling his little big brother. Raph went over and grabbed his phone, ending the video and saving it to watch later. He turned back and saw Leo covering his mouth. Looking closer, he saw that Donnie had fallen asleep in Mikey’s arms. I guess staying up for hours experimenting then being tickled by your three brothers really takes it out of you.

“Aww, he’s so peaceful!!” Mikey whisper screamed. He lent down and gave Donnie a kiss to the forehead, tearing up when he saw the smile widen on Donnie’s sleeping face. Leo carefully took off Donnie’s glasses, walking alongside Mikey and Raph as all three of them took him to his room.

“Should we tell dad?” Mikey asked as he gently laid Donnie down in his bed. He grabbed the blanket and carefully draped it across Donnie. Raph shook his head.

“Let’s wait till the morning. Let the little guy sleep for now. Seems like he needs it.” Raph put a stuffed animal next to Donnie’s hands, watching as Donnie unconsciously grabbed it held it close. Leo put his glasses on the nightstand, being sure to check that Donnie was all tucked in all warm and cozy.

He wiped his palm on whoever's chest it was resting on. It wasn't anything to worry about, just a wayward itch.

A minute passed until it came back.

A ticklish sensation dancing across his palm. Gently caressing along his palm and tracing the lines of his hand with the utmost care. He flicked his wrist.

He tried to settle into an even more comfortable position. This time the listless tickle didn't come back for a solid couple of minutes.

But this time it came back on the back of his hand. Leo truly didn't think he was ticklish on the back of his hand but the tiny tickle was wearing him down. It was a delicate tracing touch from someone's finger that swirled and twirled across his skin like a dancer. A smile naturally curled on to his face.

It really tickled.

He tried to hold still to see if whoever was doing this would stop but the sensations all built on top of each other. Each meandering loop of the finger kept layering the tickles over each other.

Normally Leo wouldn't really laugh from hand tickles. he would flinch and flap around but not really laugh.

But this time he could feel the giggles starting to escape.

"Whoever hehe that is stahahap!" Leo finally snapped, knocking his hand into someone's shell like he could swat away the feeling.

But at the same time he spoke, someone else also snapped, "Mikey, stop moving your feheheet!"

Leo now opened his eyes and was greeted with Mikey smiling embarrassingly with a blush. "Sorry guys. I'm getting a little restless."

Now he was looking, he could see that Mikey had been the one tracing his hand and also was using his foot to trace along Donnie's foot.

And despite his sheepish smile, Mikey was still tickling away at Donnie's foot and his finger was still poised over his hand. "If you still want cuddles then you'll have to deal with the tickles!" Mikey chirped happily.

"Mihihihikey!" Donnie kicked out his foot but continued to lay there with his eyes closed.

The finger returned to his palm but this time, Mikey had grabbed his wrist and keeping his hand pinned. It startled a snorty laugh from him. "Mikey!"

"Mikey, what have we talked about when it comes to tickling your serious boring brothers?" Raph's gruff sleepy voice cut through the quiet giggles filling the room.

"No?" Mikey asked, cutely turning his head to the side as if he was just a cute innocent angel.

"That if you're gonna tickle them then invite me too!" Raph smirked cockily but his voice was still whispered and sleepy.

Not that Leo felt that anymore. Any quiet sleepiness was ripped away the second he felt Raph's hand grab his knee and start squeezing.

"HAHAHA! Rahahaph!" Leo lurched up but the weight of all his brothers kept him down. He barely raised his leg.

"Tag team, bro!" Mikey grinned wildly as he immediately went to start tickling away under Leo's chin.

His and Donnie's quiet muffled giggles immediately transforming into loud unabashed laughter.

Raphael adored many things. Cute things, particularly. Things like teddy bears, pets, and flowers.. but his favorite thing was baby brothers.

Now, for such a big guy, it seemed hard to imagine he'd be good with such delicate things, but he really did his best not to overdo it in the strength department. There were times when he went a bit overboard, yes, but that never stopped him from loving all of the precious things in life.

Right now, the thing bringing him absolute joy was his youngest brother, Mikey. The box turtle was laying in his lap, belly-up with his arms held over his face. Raph had only been teasing when he had first skittered his fingers across the other's stomach, but the startled squeal it came with was too cute to resist hearing more of.

If it were another brother in his hold right now, he wouldn't be able to so much as a squeeze to the side without getting attacked, but all Mikey was doing was giggling happily, his arms hiding his face and keeping him open. Maybe, the reason was that the artist had been up all night watching scary videos again, and wanted someone to comfort him. Or, maybe it was because Donnie had gotten tickled by Leo after breakfast, and the turtle just wanted in on the fun.

Whatever the reason was, Raph wouldn't question it too much, and just enjoy the silly sounds of the younger's squeaks and laughter. The snapping turtle veeery gently switched from his fingers to his claws, dragging them slowly down his brother's sides.

Mikey yelped, body arching a bit when the nails reached a bad spot just above his hips. Raph smiled, resisting the urge to squish his sibling's cheeks, which were pushed up so far up on his face the elder was almost worried it hurt. The orange-themed turtle twisted to the side, squeaks interrupting his laughter.

"Rahahaph! EEK!- Ihit tiHIhicklehes! HehEHEH!-"

But, yet again, the younger eventually rolled back into his original position, readjusting his arms on his face. Raph propped his knee up a little bit higher, cooing at the adorable action. He crawled his fingers up, slowly climbing higher on the smaller's ribcage. Mikey giggled louder the higher his brother went, until he was hiding the rest of his face, voice cracking slightly from the pitch it was at.

"D'aww, does Mikey like the tickles?" Raph murmured, before kneading into the other's underarms. The artist shrieked, wiggling around in the elder's lap, feet kicking out. "NAHAHAH! EEK!- RAHAHAHAPHIHIEEE!"

"What? Is my baby bwother too tickwish?~ Tickle tickle!" The younger's hands moved from his face, flapping at his sides. Raph was on the verge of a cuteness overload, seeing his sibling's cherry red face, and teary eyes as he laughed.

"NOHOHO- EEK!- DOHOHON'T SAHAY THAHAHAAT!"

Mikey threw his head back in laughter when his ribs were squeezed instead, hands retreating back to his face. "RAHAHAhahaph, dohoHON'T!- EEK!-"

Raph smirked. "Whaat? Don't say tickle? Ahhtickletickletickletickle~" The younger shook his head as he flailed uncontrollably, nearly launching right out of the snapper's lap. "Your laugh is so sweet, Mikes!"

The box turtle squealed, trying to curl up when a raspberry was placed on his belly. "NAHAHAH- RAHAHAAPHIIIEE!" Raph had to push the other's legs down as he blew another raspberry, almost getting knee-d in the face. "Aww, Raph just wants to eat ya up!"
