A/N: Okay, just so you guys know this will be about a sensitive topic which some of you may find disturbing. If you don't like this kind of thing, then please don't read it. The same goes for if you think this may trigger something.

A little bit of a break from my usual happy(ish) fics. I originally didn't want to write this with TMNT, but I didn't really know what other fandom I would use, so TMNT it is. They're also human, so I guess you could call this a sort of spin-off from Kingsland High, but you don't have to read that one to get it. The only thing they really have in common is the fact that they're humans ;)

Disclaimer: I don't own TMNT

Mikey entered the room he shared with Raph, and couldn't help but grin when he looked around. The faded blue walls were suffocated in posters of various bands and cars, and the dark blue carpet was coated in a layer of clothes, toys and comics, with the occasional slice of leftover pizza here and there. When Splinter saw this room, he would have a fit. Mikey carefully manoeuvred around the obstacles on the floor until he reached the bunk beds. Not bothering to climb up to his on the top bunk, he flopped down onto the black and white sheets of Raph's bed.

"Mikey," said Raph, walking in shortly after his younger brother. "Get your fat butt off my bed" Mikey pouted but obliged, pushing himself off the mattress and down into the green bean bag on the floor.

Raph playfully kicked Mikey's leg as he passed him on his way to his own bed and Mikey grinned mischievously. "That wasn't very nice Raph," he said, sticking out his tongue.

"I can't say I care too much, Mikey." replied Raph, taking his phone out of his trouser pocket. The phone sounded, signalling a text and before long Raph began to type, his thumbs becoming a blur on the keypad.

"Who you texting Raphie?" asked Mikey, spinning his body so he was sitting upside down on the beanbag.

"None of your business Mikey, and don't call me Raphie." replied Raph, putting his phone back into his pocket.

"Sure thing, Raphie," said Mikey, grinning as he picked up a comic book which was lying near his head.

Raph growled but did nothing except for glare at the top of his younger brother's head. A knock at the door suddenly sounded and Raph picked up his pillow, throwing it at Mikey. "Get the door, knucklehead."

"Why me?" moaned Mikey, throwing the comic to somewhere behind the bean bag and rolling off of it, landing unceremoniously on the carpet.

"Because I said so, now go." Replied Raph, and watched as Mikey hopped over to the door, swinging it open to reveal their other two brothers, Donnie and Leo.

"Hey guys, come to join the party?" asked Mikey, before looking closely at their attire. "You been running or something? What's with the shorts and top?"

"We came to remind you that we have practice in five minutes." replied Donnie, rolling his eyes. "Good thing we did – it doesn't look like you remembered."

Raph immediately sprang up from the bed, his eyes wide. "Of course we'd forget!" he said, running to the chest of drawers in the corner of the room, clothes already spilling over the wood. He flung a drawer open and began to dig through, throwing anything he didn't need over his shoulder.

"Hey!" said Mikey, frowning as a pair of trousers landed on his head, closely followed by underwear. "Watch where you're throwing that stuff!" he shook his head, and the clothes fell to the floor, joining the impressive mess on the carpet.

"Do you guys ever tidy?" asked Leo, tapping a toy robot with his foot.

"Yeah," replied Mikey. "But not that often."

Raph turned around once he was ready and slapped a hand to his forehead as he saw his brother. "Mikey! What have you been doing?!"

Mikey blinked at him on confusion, "Uhh...standing here, dude."

"Well hurry up and get ready then!"

"Right!" Mikey nodded and ran to a corner of the room, immediately pulling out an orange top from the tower of clothes and comics leaning against the wall. He then ran to the bunk beds and lay on his stomach, rooting around under the bed until he brought out a pair of black knee length shorts. He grabbed his trainers which were by the door and proceeded to get changed.

"How did you know where all that stuff was in all this mess?" asked Donnie in wonder.

"This is my way of organising." replied Mikey, pulling the top on over his head.

"Geeze Mikey," said Raph. "Ease up on the junk food!" he prodded his younger brother's stomach playfully, and Mikey yelped and jumped back. He had always been the most ticklish out of his brothers. He looked down at his stomach in confusion, wondering if Raph was joking or being serious. He wasn't fat...was he? Any fat that he might have was because he hadn't fully matured yet; he was only fourteen.

"Mikey's not fat, Raph," laughed Leo, crossing his arms. "What he's got there is normal for his age. Now let's go, we're already a little late."

What I've got there... thought Mikey, looking at his stomach again. Do I have anything there? He shrugged before finishing getting changed and running after his brothers, who were already on their way to the dojo.

"You're late." stated Splinter, frowning at his sons as they entered the dojo.

"Sorry Sensei, we kinda forgot," replied Raph sheepishly.

"Yame!" called Splinter after an hour and a half, signalling the end of their training session. The four boys gathered in a line in front of Splinter and bowed to their Sensei, before walking out of the dojo, breathing heavily.

"I'm pretty spent," said Mikey, locking his fingers together and stretching his arms out in front of him.

"What are you talking about, you hardly did anything!" laughed Donnie, nudging his younger brother.

"Yeah, why are you so tired? You hurt your foot and had to sit out for ten minutes!" added Raph, and Mikey frowned.

"Doesn't mean I didn't work hard!" he replied defensively.

"Yeah, whatever Mikey," said Raph as Donnie and Leo entered their room. Mikey and Raph continued one door along before they reached their room. Raph made a beeline for his phone, and slumped on his bed, the only sound coming from him being the clicking of his fingers on the keypad.

Why am I so tired? Mikey thought, knowing he wasn't going to get any sort of conversation out of Raph. I didn't do as much as the others and they aren't as worn out as I am. He groaned and sat down in the beanbag, leaning his head back. Splinter once said I get tired more easily because I'm younger and smaller, but maybe he was just saying that so that I don't feel bad! Mikey's eyes widened and he looked at his belly, prodding it. He didn't think he was fat, but Donnie once told him that how people saw themselves in the mirror was different to how they actually looked. His abs weren't rock hard like his brothers' and although his belly wasn't sticking out very much at all, it was still there.

No, he thought, narrowing his eyes. I can't think like that. I'm fine – Leo even said I was fine!

"What he's got there," the words echoed in Mikey's mind, but the boy chose to ignore them, picking up his music player and putting the earphones in.

Mikey lay in his bed that night, thinking about what his brothers had said. They had been giving him hints that he was overweight all day, and Mikey just didn't understand why it had come on so suddenly. He was eating the same amount as them, although he had eaten an extra slice of pizza, but that was only because he hadn't had much lunch! Half of a jam baguette was not enough for a growing teenage boy.

He sighed and raised his pyjama top up to his neck, and looked at his stomach. It wasn't sticking up at the moment, but that was because he was lying down. If he got up his tummy would probably stick out again. Frowning, he pushed his top back down again and rolled over so he was facing the wall. Starting now, he was going on a diet. No more junk food for him! He was going to be skinny, just like his brothers. And with that comforting thought, Mikey drifted off to a peaceful sleep.

"Mikey, come on!" Mikey woke up to the sound of his older brother calling his name. "Get off your lazy arse and come and get breakfast!"

"Uh..." began Mikey, as he climbed out of bed. He didn't want breakfast; that was his plan for losing weight. He was going to skip breakfast every morning and then exercise every morning and every night. It was the holidays now so he had a while before school started, which meant that homework wouldn't get in the way. At least...not until he was used to this new routine. "I think I'll stay here and sort this out. You go ahead, I'll have breakfast later." Mikey said, hoping Raph would buy it. It wasn't a complete lie, but it wasn't exactly the truth either.

"If you're sure," said Raph, and left the room once Mikey nodded.

He looked at his hands and sighed. There has got to be better ways to get out of breakfast!
