[Scat, Yaoi, Anal, Huge Insertion]

“Hey, Hiro! What’s up?”

The cheery voice of a rather lanky brunette echoed through the garage where he had spent a lot of time planning and training, the garage belonging to one certain little young boy.

“You’re here early. I thought you’d take a little while longer, what with those Heartless still running around.” The boy, the black-haired Hiro Hamada who served as the leader of the Big Hero 6, smiled as he turned around in his chair. “Did you read the message I sent you, or do I need to go over it all again?”

The visitor, one from beyond this world’s boundaries known simply as Sora, nodded as he stretched and put his hands behind his head. “You sent a message? I just heard that you needed my help, and I headed straight here. Donald and Goofy tried to stop me, but I dunno why they’d want to do that.”

“I see. I’m glad to see that you’re as reckless yet as caring as ever.” Hiro said as his smile widened slightly, before clearing his throat. “You know how you helped me acquire the chip that contained Baymax’s original AI?”

Sora nodded. “Is he fully operational again? You managed to get him a new body, but that didn’t seem like it had been properly fixed up.” The boy asked, still not exactly knowing why he had been called here. Not that he needed a reason, if a friend of his needed help, then he was going to do just that.

“More than that.” The boy replied as he clicked a button on a specialized remote that he had designed for just this moment, causing the floor to shift ever slightly.

The source of the shifting wasn’t the floor itself, rather the two oversized and pleasantly plump androids that came in through the garage door, carefully closing the thing behind them as an act of common courtesy.

“Whoa, they’re just like a pair of brothers!” Sora laughed, as he walked over to one of them, reaching out with his fist to bump it, just like he had done in the past.

Only for the two to not immediately react. No, they had something else to tend to, as droplets slowly started to pour down their bodies. Almost like they were mimicking the human act of sweating…

“Eh? What’s wrong, Baymax?” The brunette said aloud, turning around to face Hiro. “Hiro, Baymax isn’t giving me a fistbump! Is he okay, or did you do something to him?” He asked, a tiny bit hurt. Sure, the android was a machine, but that didn’t mean he couldn’t feel. If he had done something to take away part of his heart…

Hiro was quick to get out of his chair once the topic of the heart came up, putting his hand on the boy’s shoulder. “No, no no no. I didn’t remove Baymax’s heart, his chip, nothing. I just did some modifications. That I thought you’d enjoy.”

“...Eh? What kind of modifications?” Sora’s eyes lit up once more as he turned towards his friend, not paying attention to the two androids as something started to grow between their thighs.

The black-haired boy nodded and slowly looked away. “I need to explain something, before I can tell you about those changes.” He started, clearing his throat. “I told you about my brother, right?”

“Mmhm. You did. He was really important to you, just like my friends are important to me. Just like you, Hiro!” The visitor chimed, doing his best not to hug him outright.

Hiro laughed a little. “Maybe a little more important than that, Sora. But besides that, he wasn’t just there to help me grow up.” He continued, as a blush slowly started to cover his cheeks. “He… He taught me a couple of things that I promised not to tell anybody, but that secret’s been eating me up inside ever since he died…”

Sora looked at him quizzically, before something bumped against the back of his head, prompting him to turn around to try and see what had done so. And then it was his turn to start blushing.

The thing that had poked him in the back of the head? Why, it was a rather substantial shaft, one that hung between Baymax’s thick thighs. In fact, it was almost the size of his arm, the thing basically ready to break anything it slid inside. And it wasn’t alone, the other Baymax had one just as large, and it was looking ready to pierce into something…

“He taught me about sex. Not just sex either. He taught me about what he was into, and he helped me get into it too. S-So, the reason I asked you to come here was… well, to help me indulge in that kind of stuff. I hope that’s not a problem, Sora.” Hiro explained, his hand slowly sliding along his android’s wonderful member…

Sora was… well, to say that he was shocked at this prospect would be an understatement. But still, he liked helping his friends. So even if this was something he never expected, he wouldn’t shy away from it. Not when he needed him most.

“Alright. So, what’s this sex thing anyway? Does it just involve our dicks, orrrr…” The hopelessly naive boy asked, giggling a little nervously. While tugging his clothes off, since he was smart enough to get that hint.

Hiro shook his head slightly. “Don’t worry. Baymax’ll handle it all. Just relax, and you’ll come to realize why I got so addicted, and wanted to get this done as soon as possible..” He explained while taking his own outfit off, letting his slim and childish body contrast against the massive rod behind him. The thing was nearly bigger than him, and he was going to play with it? How was that going to work exactly?

Sora received an answer faster than he expected, once he felt the android’s hands wrapping around his arms. He felt himself lifted into the air, his legs kicking wildly to try and regain some sort of footing…

Right before he was lowered onto the cock, the first thrust immediately broke in his virgin hole as his eyes rolled into the back of his head.

“Just like old times.” Hiro giggled as he watched the visitor trying to cope with the large insertion. He remembered when he went through the exact same thing with his brother. Though Tadashi’s cock was a lot smaller than Baymax’s, it still managed to make him so loose that he couldn’t handle himself for a few days.

Now, this cock? The one that was struggling to even slip into him from how tight the space was? He was a little worried that it would break him irreparably. But that made it all the more exciting, as he motioned for the android to pick him up and give him the exact same treatment.

His reaction to his body falling onto the cock was not unlike that of his friend’s. Sharp arousal, followed by a near instantaneous orgasm, to the point where his cum was already drooling onto the ground below. And once all of the proper cum with all of the little wriggling sperm cells finished blowing out of his urethra, the clear cum continued drooling out. He had shattered that hard.

Sora on the other hand was going through several orgasms at the same time. He was cumming again and again and again, his eyes practically trying to spin inside their sockets from how intense it felt. He had never gone through something like this, so the sensation of being so filled was too much for him.

He wanted off. But at the same time, he wanted more. He couldn’t help himself from cumming and cumming, the white sperm continuously refilling within his balls thanks to his powers. Leaving the ground an utter mess of sticky white.

Even as the two Baymaxes lifted the broken boys off their cocks, they still kept on cumming. Whether it was the subdued way that the black-haired boy’s dick drooled all his balls’ contents out like he couldn’t cum properly any longer, or the way that the brunette’s hips kept thrusting forward with every successive orgasm that quaked its way through him with a matching spray of white, they wouldn’t stop.

Their holes were spread. Their holes were aching. But most importantly, their holes were loose. Something that the more lucid of the two boys took advantage of, as Hiro shuffled his way towards his visitor. Concentrating all the while.

Sora wasn’t anywhere close to lucid. He was stuck in his little spiral of pleasure, cumming and cumming until he couldn’t cum any longer. Which meant that he didn’t see the boy coming as he suddenly pushed him to the ground and planted his ass right on top of his face, the massive gaping hole practically breathing down on him.

“Hhaaaahhh… Eat it all up, Sora..!” Hiro grunted as he pushed, a torrent of shit suddenly spewing out from his hole without any prior warning. The looseness of his hole meant that it was all sliding out with the greatest of ease, a little push was all that it needed.

The brunette was quickly coated in a complete slurry of pure filth, some of it slipping into his mouth and some smearing its way across his face. It was too much. And yet he didn’t stop, because this just added to the bizarre sense of pleasure pouring through him after he had his ass scooped out by the massive android’s equally sizable shaft.

His black-haired friend grunted and moaned as he held one hand on his drooling shaft, pumping his hand with every nugget of shit that flew out of his hole and landed on his face. It felt so good to make it all fly out. It felt wonderful. It felt like he should’ve done this ages ago, but he just didn’t have anybody to share the pleasure with. And now that he had one, he couldn’t keep it to himself...

In fact, this show of pure filth and defecating was exactly what Sora needed to understand. His subconscious picked up on the pleasure that the boy was going through, to the point where he wanted some of it himself. And so he pushed and pushed.

Perhaps he pushed a little too far, just like he came too much thanks to a couple of orgasms. Instead of pushing out his waste, he managed to push the entirety of his ass out, prolapsing his poor hole in the process.

And yet despite how strange it felt to have pushed his entire anal canal out like that, it felt amazing at the same time. It was no wonder Hiro wanted to experience this! It was amazing! How hadn’t he gone through this before..? Whether it was the sensation of pushing it all out, or the way that filthy stuff rubbed up against him, or the way it slid down his throat as he was forced to swallow it…

The black-haired genius slowly got off the boy who had served as a makeshift toilet and shit-slut, gasping as he pressed his thighs and his buns together in an attempt to close his ass up ever slightly, looking at the boy with a perplexed yet definitely-enthused stare.

He looked phenomenal, covered in all of that shit and with his ass inverted thanks to his own efforts. So much so that the boy who had gotten him hooked couldn’t help himself, pointing his cock right at the brunette’s face.

A hissing sound left Hiro’s cock as a stream of piss poured out, the golden liquid rolling across his friend’s face as it cleaned away some of the smears, while at the same time marking him. In primal terms, the boy now owned him…

Something that he was going to take advantage of, as his cock was still rock hard. And so was Sora’s, as the two looked at one another, and then at the androids that had broken their holes.

There was still plenty of fun to be had between the two. Sizably filthy fun...
