Omg I have this obsession with incest and Big Hero 6... So Incest + Big Hero 6 = Sexeeehhhhhh~~~~ xD This fanfic was inspired by a fanfiction similar to this one! I've always wanted to make a Big Hero 6, incest, or something that doesn't involve anime. Hope you enjoy this new short series! ;)

Hiro layed on his bed, shirtless, with his face down into the pillow of his bed. He snored quietly as he slept peacefully... Well peacefully for now.

"Hiro, we need to get dressed!" the voice of Hiro's brother, Tadashi, boomed through the room before wacking the back of Hiro's head with a rolled up newspaper.

"Gah!" He quickly sits up and looks around at his surroundings, patting down his bed head. "Huh? What time is it?" Hiro looks at his alarm clock beside him that had been set off, but turned off by his brother. "No! We're gonna be late!" He jumps off his bed and grabs a shirt, putting it on before running to the bathroom.

"'We?' You mean you're gonna be late." Tadashi smirks as he watched his sibling run to the bathroom.

Hiro quickly washes his face, brushes his teeth, the usual. As he does his daily morning routine, he thinks about the events that has happened. First off, he began to date GoGo. The relationship was awkward, which would be obvious because of their age gap, but they didn't really care about that. The awkward relationship never led them to kiss. All of this happened in the very beginning. GoGo began to take over the relationship, tear it apart like a useless piece of paper after a week or so. She would verbally abuse him or physically abuse him by slapping him or punching him, nothing too extreme. He would be left with bruises and red spots on his face. GoGo always thought that Hiro was a slave since he was so much younger than her. Hiro broke up with her over and over, but that didn't really get through GoGo's head. Only yesterday Hiro began cutting, he knew his brother Tadashi would eventually find out about them so he tries his best to hide it from him. Besides that, he noticed that he's gotten taller, his voice is cracking, and certain parts have gotten... Erm... 'Bigger'... Hiro knew for sure that he was going through puberty.

Soon, Hiro got into his clothes and a hoodie and went downstairs to the café where Tadashi was waiting for him at. He grabs a breakfast burrito before heading out with his brother.

"Wow, you're slow in the morning." Tadashi says as they walked.

"Shut up, I was going as fast as I could." Hiro said before taking a bite from his breakfast.

"As fast as a snail." He teased with a smirk.

"Whatever."

Hiro throws out the wrapper when he finished eating as they got to their school. They both walk in and get right to inventing and updating their projects. Hiro and GoGo were working on an invention, they were updating Wasabi's version of his rocket car. Hiro was forced to be in this project, of course, and Hiro began working on a diagram for GoGo. Everything was calm and quiet... Well for now.

"Idiot!" GoGo says before slapping the teen across the face, "I specifically said a fire rocket, not 'air'!"

"Using fire is a risk of exploding other vehicles-"

"I don't care! Fix it!" GoGo pushes him against the wall before walking away from him.

"Crazy..." He calls her under his breath. Hiro quickly fixes the design and materials that need to be contained in the vehicle. After quickly sketching it out he leaves a note saying that he's going to grab some materials... Of course, that was a lie.

Hiro visited Tadashi at his room at the school, he opens the door slowly to see Tadashi fixing Baymax. The door that was opening caught his eye and saw Hiro watching him, "Hey Hiro, what's up?" he says as he pushes the green, square disk back into it's place, closing it and smiles at his brother.

Hiro shrugged, "Not much, I just needed to get away from GoGo."

"Did she hurt you again?" His smile disappears when he steps forward to Hiro with crossed arms.

"Well, yeah-"

"You seriously need to do something about it, this can't go on forever. I'm worried about you Hiro, she can go a little extreme."

Hiro can't help but blush from hearing how worried his brother is. Why am I blushing? Tadashi's always worried about me. he thought. "I will, it's just that she's always watching me."

"When you find the chance to do it, then go for it." He then notice that Hiro's whole face is red, he gets closer to his sibling and examine's his face. "You look like a tomato."

"Huh? W-Why do you say that?" Hiro asks nervously, taking a step back and ending up with his back to the wall.

"Baymax, scan Hiro." With that said, Baymax waddles to the two and quickly scans the nervous, red-faced teen.

"A high level of testosterone. Temperature has risen 2 degrees. Diagnosis, puberty." The robot stated.

"Puberty, huh?" Tadashi smirks looking down at his brother, "So how big is it?"

"What the hell Tadashi?!"

"Haha! I'm kidding! Just kidding!" he laughs.

Hiro sits down on a chair and starts deleting texts he's getting from GoGo on his phone. "I'm going home with you today. There's no way I'm walking home alone."

"Fine with me." Tadashi says.

I'm gonna get so beat up... he thought to himself.

Drip... Drip...

Droplets of blood rolls off of Hiro's wrist into the sink as the thin blade of the razor blade sunk into his skin. He stares at the cuts he made, but they were all covered in a bloody mess.

A knock was heard from the other side of the bathroom door, a voice coming after, "Hiro? You okay? You've been in there for a while." It was Tadashi.

Hiro nearly gasps hearing his brother's voice. "Y-Yeah! I'm fine, I'll be out in a minute!" his voice cracks mid-way through his sentence out of being nervous. Tadashi chuckled hearing it and walks back to their room.

Hiro cleans up the mess, putting the razor blade into his pocket. He pulls his sleeves down and made sure that there was no trace of red before going back to the bedroom. Right away, he researches things on his computer, working on a new robot. An upgraded version of the one he used for bot fights. He began sketching, but kept doing it over... And over... And over again. Ending up with a pool of crumbled up balls of paper on his desk.

"Having trouble?" Tadashi shows up, looking at Hiro's PC.

"I can't think of anything! It's useless, I'll never figure out how to make the robot better!" He stands up and throws a ball of one of the crumbled up papers across the room.

"Oh come on, don't be like that." With one swift movement he picks up his brother and hangs him over his shoulders, holding his ankles with a firm grip. "Come on! Find a new angle!"

"Ah! Seriously, you have to-" a diagram on his wall catches his eye, it was the diagram of what him and GoGo were working on. "I got it!"

Hiro finishes up his research and sketch of what he was going to do. It was getting late and he needed rest, but that didn't stop him from working. Tadashi notices that his desk lamp was still on from where he was laying at and got up, walking over to him. Hiro hung his head as he wrote slowly, not even noticing that his sleeve is up slightly.

"Hey, you're still up? It's really late-" cuts on Hiro's exposed wrist catches his attention. His eyes widen in shock and he grabs Hiro's arm to pull the sleeve all the way up. There were cuts that looked like they were made recent, going halfway down his arm. Hiro looks up at his brother in confusion before noticing what he's looking at. He quickly pulls his arm away with a nervous look on his face.

"I-... Uh.." Hiro didn't know what to say.

"Did GoGo do that to you?" Tadashi asks with a concerned look, but with slight anger in his eyes.

"Er.. No..." He looks away.

"Then how did they-" Tadashi then realises. "You did that to yourself? Why?!"

Hiro didn't know exactly why he was doing it. He thought it was just a way to relieve him from the pain given from GoGo. "It's the only thing that helps me forget about GoGo."

"Hiro.." His eyes soften. Now he really was worried. "You should've just talked to me about it-"

Hiro stands up, knowing exactly what he was going to say, "You won't understand how I feel!" he yells at him.

Tadashi's eyes widen, he sighs and then steps towards Hiro before wrapping his arms around him.

He blushes a bright red, "What are you?-"

"Shut up... Just so you know, I know exactly how you feel."

"But-"

"I use to date GoGo..." He interrupts, his arms around his little brother tightening. Hiro's eyes went wide, absolutely shocked.

Tadashi use to date GoGo?...
