A/N: Heya! This takes place in the same AU as the previous drabble where Karai is living with the turtles. I'll be doing some moments between all of them, don't worry!

I OWN NOTHING!

Enjoy!

Brothers Part 1: Michelangelo

"Do it again, do it again!" Michelangelo chanted insistently, bouncing up and down on the bed and jolting the two of them as the bed frame shook from his weight.

Smirking bemusedly at the bouncy orange clad turtle, Karai rolled her serpent green eyes to the heavens, allowing herself to smile before she reached out, grabbing him by the shoulders and stilling him before he actually broke the bed; she'd pretty much only just got this bed, too, and the last thing she wanted to do was tell Donatello that they'd broken it. "Okay, okay," she appeased once he'd finally managed to keep himself stagnant enough to allow her to sit on the bed properly again. Crossing her legs as she turned to face Mikey properly, she tapped him on the nose once. "I'll do it one more time, and then you have to promise to keep still, alright?"

Grinning from ear to ear, Mikey nodded his head rapidly. "Okay, I won't move. Just do it again, please!"

Karai chuckled, shaking her head at his antics before she straightened her posture, her back erect and her shoulders squared as she closed her eyes. Taking in a deep breath, she focused intensely, her brows furrowing as her eyes snapped open again, and her pupils narrowed to serpent-like slits as she gazed at the younger turtle sat on the bed across from her, who gasped in delight and awe.

Her eyes wide and unblinking, she leaned towards Mikey as her forked tongue flicked outwards. Mikey remained motionless, though he couldn't restrain the giggle that escaped him as her tongue nearly touched the bridge of his nose. After a moment on concentrated silence she leaned back again, humming in thought as she tapped a finger to her chin. Mikey leaned forwards expectantly. "Well?" he asked, still beaming. "What do think?"

Karai pursed her lips, before smiling as she snapped her fingers. "…you had a chocolate, peperoni, avocado and garlic pizza yesterday…at midnight…drinking grape – no pineapple soda…and then you licked Ice Cream Kitty again."

Mikey's eyes went as wide as saucers as he gasped, before throwing his head back and laughing loudly. "Oh my gosh, you're right again!" he crowed, landing backwards on the bed with his head landing on Karai's pillow.

Huffing out a proud laugh, Karai folded her arms over her chest with smug satisfaction. "Of course I got it right," she proclaimed, examining her nails – no longer painted black – nonchalantly. "I'm always right."

Letting himself finally relax as he sprawled out on her bed, Mikey shrugged as he folded his hands atop his stomach. "Eh, that's debatable," he teased, his freckled smile returning as she smacked his shoulder playfully. "But seriously, how do you know what stuff I ate yesterday with your tongue?! It's totally weird, but so cool!"

Smoothing out the creases of her slightly over-sized blue T-Shirt, Karai shrugged. "I dunno. I guess it has something to do with the fact that snakes have an incredible sense of smell or something…but I don't think regular snakes can do that kind of thing, can they?"

Mikey shrugged again. "Don't ask me; I don't know that much about snakes," he said, moving over a little to allow Karai to flop down on her side next to him. "Maybe you should ask Donnie, since he pretty much knows everything about everything."

"He's a genius, I'll admit that, but even he doesn't know everything, Mikey," Karai grinned.

Giggling in agreement, Mikey snuggled closer to her side. Karai bit her lip at the action, debating on whether or not to return the contact or remain still. Eventually, she resulted in draping a single arm around his shoulders, using the other hand to absently pick at the threads of her baggy grey sweatpants. This whole 'loving physical contact' thing was still a rather new concept for the ex-Foot Clan kunoichi, even after a month of living with the turtle brothers and her real father in the sewers.

But she was practising. And by what she'd been told by Splinter and the guys, she was doing pretty well so far.

"Hey, Karai?" Mikey said softly, pulling Karai out of her thoughts as she looked down at him snuggled against her like a puppy. He looked up at her with those big blue eyes that she'd begun to adore despite herself. "Do you ever think about what it would be like if you were never raised by Shredder? Like, if you were raised with us by Splinter instead?"

Eyes sliding to the side, she subconsciously drew Mikey closer as her cheek came to rest on top of his head. "…sometimes, I guess…" she replied quietly, looking up at the cracks on the ceiling. "I wonder what I would've been like being raised by someone…warmer than the Shredder had been to me."

Slipping his arms around Karai's waist and holding her closer, Mikey blinked up at her. "So, Shredder was a good dad to you?" he asked. His question was innocent, but Karai couldn't help but bristle at it as she narrowed her eyes at the ceiling.

"…I can't really decide whether to say yes or no. I mean, he wasn't totally heartless, but…he didn't exactly show love either." She shrugged awkwardly. "It's complicated…"

Mikey snuggled against her. "Oh."

Looking down at the freckled turtle, Karai managed a smile as she bumped her head against his softly to get his attention. "But hey, I'm here now, right? I have my real father, and I have four brothers as a bonus. Though I never imagined having snake powers, but hey, life gives you lemons and whatever, right?" she said.

Mikey's brows furrowed. "Life gives you lemons? I never got any lemons."

Karai actually laughed at that as she swatted his shoulder again, pulling herself up into a sitting position once he released her. "You are a lemon," she snickered, tapping the bridge of his nose and earning a giggle from him.

Spying her make up box on her desk on the other side of the room, an idea came to mind as she looked back down at the turtle still lying on her bed. "We still have a few hours to kill before you guys have to go on patrol. You want a makeover?" she asked with a nonchalant shrug.

Mikey's eyes instantly lit up, and he leapt forwards and wrapped his arms around her shoulders in a tight hug as he pulled her to his chest. "Yes yes YES! I thought you'd never ask!" he cried excitedly. "I've always wanted a makeover!"

Stunned for a moment by the sudden embrace, Karai blinked several times, her mouth opening and closing continually like a goldfish before she could get her brain to work again. Her hands twitched with indecision before her arms came around his shell as she returned the hug. "You're a weirdo, aren't you?" she teased.

Mikey only laughed. "Like A Turtle Do, sis! Now let's get fabulous!"

Karai giggled.

When Donatello emerged from his lab to grab a snack from the fridge, he was met with sounds of snickering coming from in front of Karai's bedroom door. He turned around to find Leonardo and Raphael, holding a video camera as they peeked through their sister's door, giggling like a pair of high school girls invading a boys' locker room. Raising a brow, Donnie bemusedly walked over to see what was so funny…which was when he finally heard the very out-of-tune singing coming from the bedroom.

Peering over Leo and Donnie's shoulders, he was quickly forced to slap a hand over his mouth to stifle the burst of laughter that threatened to erupt.

"It's only for todaaaaay!" Karai belted out.

"It's only for todaaaaay!" Mikey echoed.

"It's agony to waaaait!"

"It's agony to waaaait!"

"Tell the guards to open up…THE GAAAAAATES!"

"THE GAAAAAAAAATES!"

Mikey and Karai, both of them holding hair brushes to their mouths, were singing 'For the First Time in Forever' at the top of their voices as they pranced around the bedroom. Not only that, but Mikey's face was decorated in vibrant makeup over his eyes and lips that made him look utterly foolish.

What in the name of shell was going on?

They were just approaching the end of their song when Raph tapped Leo on the shoulder, wriggling his eyebrows with a grin that was borderline predatory. Leo returned the grin before handing the camera over to Donnie, and they both took a few steps back, waiting for their cue from the song. Donnie, realizing what they were about to do, took a few steps to the side whilst continuing to film his siblings in the room.

This was going to be good.

"Cause for the first time in forever," they sang together in unison, "for the first time in foreveeeerrr…nothing's in my waaaaaay – AAGH!

Leo and Raph charged into the room, tackling Mikey and Karai to the ground before they could get out of the way in time. Donnie finally lost it as he, along with Leo and Raph, fell into helpless hysterics. Mikey was son to join in. And despite her annoyance upon being brutally tackled to the floor, Karai found herself laughing along with them.

And if a few tears managed to slip through, well, that was between her and Michelangelo.

A/N: Gotta love the sibling fluff! And can snakes actually do that sort of thing? Ah well, see you next chapter!
