Summary
     Hidashi AU where Tadashi survives the fire. Baymax accidentally
     pushes the two brothers into an incestuous circumstance
Notes
     I am moving this from my SFW account to my NSFW account
      
     Oi oi, gentle viewers! So, I've shipped Hidashi ever since I first
     saw Big Hero 6. I've also had the idea for the fic since i walked out
     of the theater after seeing it for the first time. In this fic,
     Tadashi survives the fire, and he and Hiro start fucking. I don't
     know how long this fic will be. But this first chapter is just to set
     everything up. Chapter two, which should come out about a week after
     this one, has most of the NSFW content. Anyway, I hope you enjoy the
     fic!
***** Chapter 1 *****
Tadashi clapped with the rest of the small crowd as he watched his little
brother, Hiro, walked shyly onto the stage to give his presentation. The
younger boy's days of Bot-Fighting were finally paying off. Who would have
thought that somebody as young as Hiro would be able to build thousands of
nanobots capable of being programmed by brainwaves alone? And that's what
Professor Callahan was about to find out.
Hiro waved acknowledgement to the crowd, and began his presentation. Tadashi
smiled widely. His little brother looked so cute up there, with his hair
constantly getting in the way, and the hesitant way he started his
presentation.The elder brother was gushing with pride and affection for Hiro.
He was so glad that Hiro had already gotten this far in life. There was no
doubt in Tadashi's mind that this would win Hiro a spot in the "nerd school" as
they called it.
Tadashi watched as Hiro walked the length of the stage, now articulating more
strongly, and he felt a twinge of something that felt alien in this situation.
Was it. . . arousal?
Tadashi shook himself. Now was not the time and this was not the place to be
sidetracked by unnecessary thoughts. Hiro was giving what looked to be a damn
good presentation, and Tadashi was there to support him.
Right on cue, just like they'd practiced, Hiro put the controller on his head,
and microbots began to swarm through the crowd, causing gasps, yells, and a few
spilled drinks.
Hiro explained how the microbots reacted to his thoughts, and the bots in
question began morphing into various shapes, and started to swing Hiro through
the crowd, which was now staring awestruck at this 14 year-old boy's mind-
bending invention.
The presentation was just about flawless! Even Tadashi, who had helped Hiro
prepare for it, was left speechless. But then Tadashi spotted the one thing
wrong with Hiro's presentation, and he grinned broadly. Now that he had seen
it, Tadashi knew he had to tease Hiro. He would make sure the younger boy never
heard the end of it!
 
..............................................................................
 
Hiro took a deep bow, grinning from ear to ear as he ended his presentation.
The crowd erupted with applause that was louder than they had given any other
presentation so far. Hiro beamed somehow even wider as he saw his brother,
Tadashi, clapping and cheering hardest of them all.
Hiro had, after all, done this for Tadsahi. Ever since their parents had died,
Tadashi had been the person Hiro was closest to, Aunt Cass included. Everything
he did, he did to make Tadashi proud. There were added bonuses, like how
friggen cool making robots could be, but Tadashi was truly at the heart of
Hiro's motivation.
And how could Tadashi not be proud? This latest invention of the nanobots
showed what a success Hiro was. For Hiro knew they had been successful. There
was no way for Callahan to not let him into Tadashi's nerd school!
Hiro stepped down off the stage, then pushed through the crowd, making his way
to Tadashi. He beamed up at his older brother, then threw his arms around him.
Tadashi smiled and hugged Hiro back.
"Hiro, you were incredible!!" Tadashi said, lifting his younger brother up off
the ground. Hiro laughed as Tadashi spun him around in a circle through the
air.
As Tadashi put Hiro down, he caught sight of their Aunt Cass, who was pushing
through the crowd to get to them.
"Oohhhh, Hiro, that was absolutely amazing!!!" Cried Aunt Cass, throwing
herself onto her youngest charge. "I'll be very surprised if you don't get into
the College."
"So will I!" Said a hearty and kind voice. Hiro turned and looked into the
wizened face of Professor Callahan. A large grin was splayed across his
features.
"Hiro, I'd like to welcome you to my University" Callahan said softly, handing
Hiro an important-looking envelope. "I firmly believe that this is the place
for you. You can easily broaden our horizons, and break the boundaries of
science here. You could easily improve upon these nanobots, make more, or move
on completely. Either way, you're ready to be here."
"I-I don't. . . Um, th-thank you, sir!" Hiro gasped, taking the letter from
Callahan feverishly. "I won't let you down!"
"I know you won't. You're too damn good for that." The legendary professor have
another smile, turned, and walked away.
Aunt Cass burst into a fit of silent cheering and screaming. While she
celebrated, Tadashi's friends- no, Hiro's new classmates!- Wasabi, Honey, Gogo,
and Fred squeezed over to greet Hiro.
Hiro was immediately showered with "congratulations", and "you did it!". As
much as Hiro liked the positive attention, he was starting to feel slightly
suffocated.
Tadashi seemed to notice this. He muttered "c'mon, let's find somewhere
private. We can miss the next presentation. Nothing is going to blow my mind
after what you just did. Plus, you could use the space." Hiro nodded, and
Tadasho waved the others off.
"We've got to get him washed up." Called Tadashi, leading Hiro away from the
others. "No, really. I'll take him. You all stay here. We'll be back soon. You
good, Hiro?"
Hiro nodded again, and Tadashi grabbed his hand and led Hiro through the
audience and out a door leading to a long hallway. They hurried into the first
unlocked room they could find, and shut the door behind them.
They had entered a classroom full of desks and lab equipment. It was dark, but
Hiro could easily see Tadashi when they moved to the center of the room, as
there was light from the city filtering through the window at the far side of
the room.
Tadashi and Hiro say on one of the desks, an the eldest brother turned,
beaming, to the younger.
"Hiro, I'm so proud of you! I know you must be tired of hearing it already, but
I really am. You and I are going to be classmates now! How awesome is that, ya
big nerd?!"
Hiro grinned sheepishly down at the floor. He didn't want to admit it, but he
would never get tired of hearing Tadashi say he was proud. In fact, just those
few words by Tadashi had Hiro burning with emotion. He loved his brother more
than anything. It was a dream come true that Hiro was about to start working
with him while also developing new technologies.
"I can't wait to get started!" Hiro said. "But I'm going to have to come up
with some good ideas to research and develop at the nerd school. . . It'll be
hard to beat this presentation, though. That is, if it was as perfect as you
say it was!"
"Weeeeellllll, there was one, small problem with the presentation. Nothing that
discredits you. . . It's just kinda embarrassing."
"What?!" Hiro gasped. "What problem?!"
Tadashi laughed and slid off the desk, and moved so that he was standing in
front of Hiro. "Well, you kinda had your pants unzipped the whole time. . . "
Hiro let out a gasp, looked down, and let out a louder gasp. He made to quickly
zip himself up, but Tadashi stopped him by grabbing his wrists. Hiro felt
himself go beet red with embarrassment.
"Now, while it was completely unprofessional, and made you look like a bit of a
dork," Tadashi smiled and Hiro's breathing quickened, "I actually found it kind
of cute. And I mean, nobody is going to say 'that Hiro kid had the best
invention, but since his pants were unzipped I'm going to throw him out."
Hiro laughed slightly. "Alright, you've made your point. I looked like a doof,
but with no harm done. Now will you let me zip up?"
"Oh, allow me! The king of tonight's performances should not be burdened with
the zipping up of his own pants" Tadashi said, laughing slightly as he adopted
a slightly snooty English accent.
Hiro snorted with laughter as Tadashi squatted down in front of him, face
inches away from his crotch. Then Hiro looked down again, and nearly choked.
Somehow, his penis had begun to protrude slightly, so that the head of his
penis was pushed out of Hiro's fly. Tadashi's face was now less than a foot
away from Hiro's penis head, which was perfectly outlined by his white
underwear, and protruding from his fly.
Tadashi noticed and frowned slightly. He felt that same arousal he'd felt
during Hiro's presentation come back, only this time it was stronger. With
great difficulty, Tadashi pushed the feeling down.
Hiro saw a look come over his brother's face and knew he must have noticed
Hiro's penis. Then, to Hiro's bewilderment, he found he both felt embarrassed
by this, and motivated by it. His penis went slightly hard.
Tadashi reached forward and began to tuck Hiro's penis back into his pants.
"Shit!" Hiro thought. "Please don't notice I'm hard! Please, please, please
don't notice!"
Luckily, Tadashi didn't seem to notice. He quickly zipped Hiro up, and stood
shakily.
"Th-there you are, m-my king!" He said in the same snooty accent, as though
nothing out of the ordinary had happened, although this time his voice shook
slightly.
Hiro had turned red again. Luckily, he was back to being flaccid now.
"We should, erm, head back to the presentations, now."
Tadashi nodded, but before the two red teens could take a single step towards
the classroom door, an earsplitting mechanical wail slashed through the room.
Hiro and Tadashi clapped their hands over their ears, jumping with surprise.
"WHAT'S GOING ON?! WHAT IS THAT?" Hiro shouted at Tadashi over the wail of the
siren.
"THAT'S THE FIRE ALARM!" Tadashi yelled back with fear as urgency in his voice.
"FOLLOW ME! I'LL GET YOU OUT OF HERE!"
Tadashi removed a hand from his ear, and grabbed Hiro's wrist firmly, and began
dragging him towards the door. But yet again, they had only gone a few steps
before stopping.
"WHAT'S WRONG?" Hiro shouted over the din.
"I SMELL SMOKE!" Tadashi reached out a hand and placed the back of it against
the food. He withdrew it quickly, and started dragging Hiro across the room to
the other side.
"THE DOOR WAS HOT! FIRE IS ON THE OTHER SIDE. WE'RE GONNA HAVE TO CLIMB THROUGH
THE WINDOW!"
Hiro could smell the smoke now. It was getting stronger and stronger, filling
up the room.
Tadashi began fumbling with the locks on the windows. Hiro noticed the room
growing increasingly hotter. There was an unsettling red glow coming from under
the door, and the room itself was growing dark with smoke. Hiro coughed heavily
into his sleeve, eyes watering.
Tadashi snapped the locks open, and pushed the window outwards. "CLIMB
THROUGH!" He ordered, covering his face with his sleeve as the smoke was rushed
towards the open window.
Hiro obeyed, hoisting himself up onto the window frame and scrambling through.
He gasped for air, and his feet found earthy ground. A split second later,
Tadashi had squeezed through next to him.
"Come on, we've gotta move!"
The two brothers started running fast away from the building. The sounds of the
fire alarms died away, although Hiro's ears were ringing, and they made their
way around to the front of the building from a safe distance.
"HIRO! TADASHI!! THANK GOD!" Cried a voice from up ahead. The boys skidded to a
stop, turning their heads to see who had called. They first heard sirens that
told them the fire department was there. Then, suddenly they were being bowled
over by a group of people.
"H-honey! Aunt Cass! Wasabi!" Tadashi groaned as all his friends and he and
Hiro's aunt hugged them tightly.
"Are you OK?! Are you hurt!!? Oh, I was so worried!"
"Don't worry, Aunt Cass. We're Fine. Tadashi got me out safe. I'm just a bit
jaded and soot-covered." Hiro said.
Aunt Cass collapsed into a heap of relieved tears. Honey, however, turned
urgently to Tadashi.
"Professor Callahan is still in there! So are Hiro's nanobots!" She pointed
behind them at the building. Hiro turned, and let out a gasp of shock. It was
an orange inferno. Flames were leaping out of the windows forty feet into the
air, and a thick, black cloud was billowing away into the night.
"I have to save him!" Tadashi said, making to move towards the hellish
building. At once, Hiro, Cass, Wasabi, Fred, Gogo, and Honey all grabbed onto
him and pulled him back.
"It's too dangerous!" Said Aunt Cass. "I won't allow it!"
"Tadashi, it's too late, man. There's nothing anyone can do." Said Wasabi,
soberingly.
"But, Hiro's bots. . . And his place in school!" Tadashi said desperately.
"I can rebuild the bots if I need to." Hiro said reassuringly.
"And Hiro was accepted to the school. Everyone know it. Tadashi, there's
nothing to be done!" Wasabi gasped, clearly devastated by the fire.
Tadashi took a deep breath, then nodded. He pulled Hiro close to him, hugging
him tightly, and turned to watch the building burn

Chapter Notes
See the end of the chapter for notes
Aunt Cass rushed Hiro and Tadashi into the car as soon as they were cleared to
go by the Fire Marshall.
 
"I still want to take you to a doctors office and get you both checked out!"
Aunt Cass said loudly as her eyes flickered over the two brothers in the car
mirror. "You just look terrible!"
 
"Really, Aunt Cass, we're fine. Just covered in soot. What we need is to get
clean, and then rest." Tadashi said in a reassuring voice. He seemed to be
getting over the shock of the fire, and of the possible demise of Professor
Callahan.
 
"I just . . . I don't know. I'd feel better to get you checked out." Cass said,
biting her lip.
 
"How about this," Tadashi said. "We go home, get cleaned up, and I'll use the
project I've been working on- you know the one- to check me and Hiro out. If it
finds any problems, I'll get you, and we'll immediately go to a hospital. If it
doesn't, you have to let us get some sleep."
 
"What project?!" Hiro asked, but Cass cut across him.
 
"That sounds good, I guess. . . Yeah. That sounds like the best thing for you
two boys."
 
"What project?!" Hiro repeated. Tadashi smiled at him.
 
"You're gonna love it,
little bro!"
 
Try as he might, Hiro couldn't get any more information out of him.
 
When they arrived at the house, Cass told the two boys to go and take showers,
and that she was going to bed.
 
Hiro, however, was wide awake. He ran with Tadahi up two flights of stairs to
his and Tadashi's room.
 
Tadashi opened the door, and the two hurried into the dimly lit room. The door
snapped shut silently.
 
Hiro flipped a switch on the wall, and the room was thrown into the light,
revealing two beds, and a jumble of electronics, posters, metal, and various
screens and gaming systems. A curtain divided the room, separating Hiro and
Tadashi's places of dwelling.
 
"We'll do the tests after we shower." Tadashi spoke in a calm and soft voice,
as if he thought Hiro was more shocked by the fire than he was. In truth, Hiro
wasn't shocked by it at all. At least, not now that he was away from it. He
could easily rebuild the nanobots, and he had never been close to Callahan.
He'd only ever met the man twice, and both times had lasted less than three
minuets.
 
Hiro nodded at Tadashi, then opened a drawer in his cabinet. He pulled out
another pair of jeans, a shirt, and underwear. He wasn't going to bed, so why
put pajamas on?
 
Hiro watched as Tadashi did the same. Was he staying up too?
 
Tadashi caught Hiro's questioning glance, and have him a reassuring smile. "I'm
staying up to make certain you're alright. I'm not even tired anyway, so it's
cool."
 
Hiro nodded. He wondered what sorts of tests Tadashi had to perform to make
sure he was alright? Hopefully nothing uncomfortable, like strapping Hiro down
onto a table and pushing things inside him . . .
 
Tadashi cleared his throat. "Ahem, erm, Hiro, you think maybe we could go to
the showers now?"
 
"Oh, uhh, yeah!" Hiro quickly kicked off his shoes and pulled off his socks.
"Yeah, we definitely need to do that," Hiro muttered under his breath. "You
more than me, cuz you always stink!"
 
Tadashi mimed slapping Hiro on the back if the head, then chuckled softly.
"Alright, little man, let's get cleaned up."
 
Both boys hurried out the door, heading for different bathrooms. Hiro made it
to the bathroom that he and Tadashi shared first, so Tadashi had to stump down
to the second floor to use the guest bedroom.
 
Hiro let out a sigh of relief and he snapped the door shut and turned the lock.
A shower was exactly what he needed. He was covered from head to toe in sweat,
grime, and soot.
 
On top of that, he just needed to relax. He may be wide awake, but he was still
sore and tense. Of course, it was nothing a little warm running water couldn't
fix.
 
Hiro set the bundle of fresh, folded clothes down onto the sink, then wandered
over to the shower, and bent over. He wrapped his fingers around the shower
knob, and turned it to the left.
 
Hiro ducked and shot backwards to avoid being doused in frigid water as the
shower began to spit the stuff out.
 
The 14-year-old lifted his arms up and pulled his shirt up over his head. He
flung it down into a random heap on the floor. Hiro shivered slightly as the
cold air touched his bare chest.
 
Hiro lowered his arms and began to unbutton his pants. He felt a tightness he
hadn't noticed before release itself from around his waist. Hiro unzipped and
let the pants drop to the floor.
 
Hiro moved back over to the shower and put his hand in the spray. It was
getting warm. Just a minuet more and it would be perfect.
 
Hiro pulled off his underwear, and tossed it onto the pile of crumpled clothes
he had made in the middle of the floor.
 
The youngest Hamada ran a hand across his naked body. He was filthy. Soot was
covering most of him. His hand strayed down to his uncircumcised penis. It was
one of the only parts of him that was clean.
 
He cupped it in his hand, and thought about earlier that day when it had almost
betrayed him. What was he doing, getting hard about Tadashi? His own brother?
His own, very sexy, brother. . .?
 
Hiro shook himself. He couldn't think these thoughts! They were wrong! What was
worse, he could feel himself starting to get hard again. He moved his hand away
from his penis. He would not succumb to this disgusting urge.
 
Hiro pushed aside the shower curtain, and stepped into the warm spray of water.
He let all thoughts of his brother flow away, and set his focus instead upon
cleaning himself.
 
He spun in the shower, lifting his arms so that the water could wash away as
much of the grime and soot as possible. Hiro felt the warm water relaxing
himself, and sighed as his muscles eased up, unclenching.
 
Picking up a bar of soap, Hiro began running it down his body. The soapy scent
filled his nostrils, relieving him of the smell of smoke. He moved the bar all
over his chest, arms, and back, making his skin wet, shiny and clean.
 
Next, Hiro started working on the legs. The bar of soap rubbed a path up an
down the inner thighs and knees. Hiro rubbed it softly on his penis. He watched
the way it left little bubbles behind on the shiny, wet skin.
 
Hiro proceeded to pull back his foreskin, revealing a shiny purple head. He
cleaned that area quickly, then bent over ass in the air and spread open, so he
could reach the bottom of his legs.
 
When he was finished with that, he took advantage of his position to reach back
and run the bar of soap down his ass crack. He let out a small involuntary
shudder when the soap passed over his asshole.
 
The boy straightened up and began washing himself off. He put the bar of soap
back, and began running his hands over his body to help push all the soap off.
He bent forward to run his hair through the water, and reached back with his
hand again, and pushed a finger through his crack to get the soap out.
 
He shuddered again, and felt the sudden urged to shove his finger inside of
himself. He felt his penis get hard once again. Hiro moaned, and pushed his
finger against his hole, then froze. Had he already forgotten about the
wrongness in these feeling he'd thought about not 10 minuets ago?
 
He moved his hand away, stood up straight, and finished rinsing himself off.
Hiro turned off the water, climbed out, and grabbed a towel. He would not
succumb to these dirty desires. He would dry off, get dressed, and let Tadashi
do his tests, and that was it!
 
Little did Hiro know that one floor down, in the guest bathroom, his older
brother Tadashi had just had a nearly identical experience in his shower.
 
--------------------------------------------------------------------
 
Hiro hurried into the room he shared with his brother, running a hand through
his still slightly damp hair. He shut the door behind him, and said turned to
spot Tadashi, who was pulling something around his bed.
 
"alright, let's do some tests!" Hiro called, clapping his hands together.
 
"Hey there, little bro!" Tadashi grunted as he dragged what looked like a
large, red, metal suitcase out in front of his bed.
 
Hiro threw the bundle of dirty clothes, which he had been carrying, into a
clothes bin by the door. "We gonna do these tests or what, man? The sooner
they're done, the sooner I can sneak into the bakery for a snack!"
 
"Alright, Hiro. I'm going to show you what I've been working on the past few
months." Tadashi said, motioning his brother over to his side of the room and
opening a crate by his bed. Hiro followed him over to the crate, curious as to
what his brother had been building, and also to what this had to do with
medical tests.
 
"What is it?" Hiro asked, looking blankly at the red case in front of him.
"What does it do?"
 
"Allow me to show you" Tadashi grinned, then, quick as a flash, his arm shot
out and he pinched Hiro hard on the arm.
 
"Ow! Hey! What the heck, man?!" Hiro cried, wrenching his arm away and rubbing
the spot Tadashi had pinched, which was turning red.
 
"I thought you were supposed to fix my injuries, not make mo-"
 
Hiro stopped dead. The large red suitcase in front of them had snapped open.
There came a loud sound of rushing air, and what looked like a large, white
balloon began to inflate out of it.
 
"I give you," Tadashi said as the thing inflated fully, "Baymax!" Hiro watched
as a large, round, bubble robot was inflated before him.
 
"Hello," it said in a pleasant male voice. "I am Baymax, your personal
healthcare companion. How may I be of service?"
 
Hiro's jaw dropped. "You made a hospital robot?"
 
"Isn't he fantastic?! Voice activated and all. only recently completed my work
on him. He's 100% fully functioning now. He's going to scan us and make sure
we're OK!"
 
"H-he is?" Hiro asked timidly.
 
"Don't worry, it's nothing invasive. Look, I'll go first."
 
Tadashi stepped closer to the bubbleman, and said "I would like you to do a
wellness check."
 
"Affirmative" said the droid. A hole opened in its chest, and a blue light came
out of the hole. It was a scanner. The light moved up and down Tadashi's body
several times, then stopped. The light turned off, and the hole in Baymax's
chest closed.
 
"Subject is in excellent health. Subject is physically fit, and appears to have
no bodily damage whatsoever."
 
Tadashi turned to Hiro, beaming. "You see?! He's amazing. Come on, now. Get up
here. I need to make sure that you're OK, too."
 
Tadashi stepped aside, and Hiro walked forward uncertainly, stepping before the
droid.
 
"Baymax," Tadashi said. "Perform the same wellness test on my little brother."
 
The process started again. A hole opened in Baymax's chest, and a blue light
roved over Hiro's body. After a few seconds, the light stopped, and Baymax
spoke.
 
"Subject is in excellent health. Subject is physically fit, and appears to have
no bodily damage whatsoever."
 
"Ha! See, I told you I was-" Hiro began, but Baymax cut across him.
 
"However, I do detect unusual hormonal activity. This has led me to conclude
that the subject has recently begun puberty."
 
Hiro's spirits sank, and his face burned red. He choked on the air he was
breathing.
 
"Puberty may cause acne, emotional instability, mood swings, and hair growth in
areas such as the face, chest, armpits, stomach, buttocks, and penis."
 
The robot fell silent. Hiro was burning with embarrassment.
 
"Well well well." Tadashi said, grinning. "Look who's in puberty!"
 
"I-I'm not. . . I haven't!" Hiro sputtered. "I'm not in puberty!"
 
"Sure you are. Baymax doesn't make mistakes, and he says you are."
 
"Prove it!" Hiro said, then immediately knew he'd said the wrong thing.
 
Tadashi grinned even wider, and stalked towards Hiro. "OK, I'll prove it." Said
the older brother. He leaned in close to Hiro, examining his face carefully.
 
"No sign of hair or acne on your face. But then Baymax did say you'd only
recently started puberty."
 
"I told you I haven't!" Hiro growled.
 
"And I'm going to prove that you are!" Tadashi shot back. "Alright, first, a
small education."
 
Tadashi lifted his arms, and pulled off his shirt. All thought of protest left
Hiro's mind instantly as he laid eyes on his brother's muscular chest, his six
pack abs, and his round nipples. As Hiro's eyes took in the magnificent view,
he felt his cock go slightly hard.
 
"So," Tadashi began. "You can see that I have hair growing on my chest, and
some on my stomach." He motioned to the trail of hair leading from his belly
button down under his pants. "You can also see hair growing under my arms."
Tadashi lifted his right arm to show Hiro the bush of hair growing in his
armpits.
 
"That hair all started growing when I hit puberty. And it will happen to you,
too."
 
Then, in a sudden flash, Tadashi had Hiro's arms pinned above his head. The
older brother pulled Hiro's shirt off, and threw it across the room.
 
"Hey! Dude, you could have just asked me to take it off!"
 
But Tadashi wasn't listening. He was examining his brother without his shirt
on. Hiro was still muscular, but his muscles were nothing like Tadashi's.
 
"Hmmmmmnnnn. . . I don't see any hair. Arms up." Hiro complied, lifting his
arms and showing smooth, hairless armpits.
 
"Damn! You're a tricky one, aren't you? Alright then, next step!"
 
And before Hiro could react, Tadashi had straightened up, and began to take off
his pants and underwear.
 
Hiro felt his breath catch in his throat as he watched his brother strip down
before him. Tadashi's pants fell to the floor in a bundle, as his underwear
soon followed. Tadashi was now stark naked in front of Hiro, his large,
flaccid, uncircumcised penis swinging slightly. Hiro felt himself go completely
hard.
 
He had never seen his bother fully nude like this before. Sure, they shared a
room, and Hiro often snuck glances when they were changing, but he'd always
been affraid of being caught looking by Tadashi, so he'd never seen much. But
now Tadashi was purposefully showing off his privates for Hiro! And the younger
brother couldn't help but feel very aroused.
 
"Now, you see that I have a lot of hair growing around my penis." Tadashi said
as though this was a normal conversation. "It's also growing on and in my, erm,
butt." Tadashi turned around an spread his butt cheeks open, showing Hiro more
hair. Hiro caught a glimpse of Tadashi's butt hole, and his heart skipped a
beat.
 
Tadashi turned back to Hiro, showing his penis again. He started to talk more
about puberty and hair, but Hiro wasn't listening. The younger boy took a step
forward, staring at his older brother's penis. Hiro longed to get on his knees
and touch Tadashi's penis, to play with it (using the excuse of wanting to
learn about puberty, of course).
 
Hiro noted somewhere in the back of his mind that some sticky, wet substance
seemed to be leaking out if his penis and into his underwear. He wondered
vaguely what it was, before being jolted back to reality by Tadashi's voice.
 
". . . . So I won't be judging if you've hit puberty based off the amount of
hair, but by if you've got hair at all."
 
Hiro's penis shifted slightly. He needed to touch Tadashi's penis without his
brother realizing the true reason why. Hiro leaned forwards, and was about to
stretch out his hand when, quick as he could, Tadashi crouched down, his face
once again just mere inches from Hiro's crotch. Tadashi stretched out his arms,
and slipped his fingers under Hiro's wasteband.
 
"Now, let's see, once and for all, if you've hit puberty."
 
"Shit!" Hiro thought, eyes widening as Tadashi slowly started to pull down
Hiro's pants and underwear. "I can't let him see my boner! He can't know how I
feel about him!"
 
"Tadashi! W-wait! I don't-!"Hiro began desperately, but it was too late.
Tadashi pulled down Hiro's pants, and Hiro's boner sprung free.
 
Tadashi froze, and so did Hiro. The head of Hiro's penis was protruding from
his foreskin, and was less than two inches away from Tadashi's wide eyes.
 
Hiro was beet red now. He could tell Tadashi was shocked. So shocked, he didn't
notice the small amount of black hair sprouting around Hiro's cock.
 
Tadashi licked his lips nervously. Hiro wished with all his might that his
penis would stop being hard, but he was far too aroused for that to happen.
 
"Hi-Hiro. . . Is this really how you feel?" Tadashi asked in a low whisper.
Hiro nodded slowly. Tadashi seemed to be taking this much better that Hiro had
thought he would. And was it just his imagination, or was Tadashi getting hard
too?
 
"Have you ever had sex?" Tadashi asked, and Hiro resisted the urge to moan as
he felt his big brothers breath on the head of his penis.
 
Hiro shook his head, and watched as a sticky, clear strand of precum began to
slowly leak out of his penis.
 
"I've n-never even masturbated. I mean, I know all about sex and masturbation
and everything, and I watch you change clothes whenever I can, b-but I've never
actually d-done anything because we sh-share a room, and I didn't want to get
c-caught."
 
Tadashi let out a gasp of air, as if he had been holding his breath. Hiro saw
that Tadashi was definitely hard now. As Hiro saw his big brothers hard-on, he
let out a low, desperate moan.
 
Hiro looked into Tadashi's eyes, pleading silently. Tadashi nodded to show his
understanding, and the spell that kept the two brothers relatively frozen
shattered.
 
Tadashi pulled Hiro forward, and opened his mouth. Hiro pushed his cock inside
Tadashi eagerly. Tadashi closed his lips around his younger brother's penis,
and swirled his tongue around the head of the boys penis.
 
Hiro's body was racked with pleasure. He let out a small "o-oh!" And grabbed
Tadashi's shoulders for support.
 
Tadashi's eyes fluttered slightly, and he pushed the tip of his tongue under
Hiro's foreskin, then moved it around the circumference of the boy's cock.
 
"Oh sh-shit, Tadashi!" Cried Hiro, his knees shaking slightly. Hiro immediately
clapped a hand to his mouth. Cussing was firmly forbidden in their household.
But Tadashi only raised an eyebrow and winked at Hiro.
 
Hiro breathed a sigh of relief, but almost immediately sucked it back in as
Tadashi swirled his rough tongue across the sensitive parts of Hiro's cock.
 
Hiro grabbed onto Tadashi's head. Hiro began to make small thrusts with his
hips, pushing his cock in and out of Tadashi's mouth. This felt so right, as so
wrong.
 
The pleasure was stating to increase. Hiro stopped thrusting, leaned his head
back, moaning, and let Tadashi do the work. Except. . . Tadashi wasn't working!
He had stopped.
 
"Wh-what? Tadashi. . . More?" Hiro moaned, but Tadashi shook his head and stood
up. Hiro looked inquiringly at his brother. Why had he stopped? Was he having
second thoughts?!
 
"Hiro, based on what you told me a minuet ago, I'm guessing you haven't ever
cum?"
 
"What?" Hiro asked. "C-cum?"
 
"Ejaculated" Tadashi responded with a small smile. Hiro shook his head no, and
Tadashi's smile widened.
 
"I want to see it when you do" he said, then gently grabbed Hiro's shoulders
with his hands. Tadashi pushed Hiro slowly down onto his bed. Hiro laid down
his head on Tadashi's pillow. He was panting slightly, and his cock was
pointing straight up.
 
Tadashi crawled onto the bed. He positioned himself so that he was on top of
Hiro. He pinned Hiro's arms above his head, and peered down at the boy-at his
brother- with a glint in his eye.
 
"Hiro," Tadashi whispered, "spread your legs."
 
Hiro complied, and Tadashi slid down the bed so that his face was at Hiro's
ass. Tadashi looked between Hiro's spread legs and whistled. The boy's he was
tight, clean, pink, and beautiful. And his cock! His cock was amazing. Already
at least 6 inches, and at such a young age!
 
"Hiro, you're packing quite the arsenal here!" Tadashi said in an impressed
voice.
 
"Um, hehe, thanks, I guess?" Hiro said uncertainly.
 
"No problemo, little bro! Now, I don't have any lube, but I do have something
just about as good." Tadashi said. He reached out his hand and stroked Hiro's
hole with his finger. Hiro giggled and clenched his hole.
 
"That tickles!" Hiro said, grinning.
 
Tadashi laughed. "My bad!"
 
"S-so what's the alternative you've g-got to lube?" Hiro stammered. It was
clear that he was very nervous about this sexual encounter. Nervous, but also
eager.
 
Tadashi spat into his hand, winked at Hiro, then started rubbing it into his
little brother's asshole. Hiro giggled at first, but the laughter quickly gave
way to moans, as Tadashi began adding pressure to the hot, wet finger.
 
Tadashi grinned hungrily down at Hiro. "You like that, genius?" He said with a
chuckle. He pushed the tip of his middle finger inside of Hiro, and the boy
gasped loudly.
 
Tadashi pulled out the finger briefly, but only to add more saliva. He quickly
thrust his finger back inside, only this time he went deeper. Hiro let out a
loud moan as Tadashi pushed in past his knuckle.
 
It was a strange yet thrilling experience for Tadashi. He had never felt inside
an asshole before. Not his own, much less his brother's. He was almost greedily
feeling around, making Hiro squirm.
 
"I- I think I'm ready" Hiro panted, looking down at his brothers finger
disappearing into him.
 
"I dunno, Hiro," Tadashi said, "it's your first time, we don't have real lube,
I've only put one finger partially inside you for a minuet or so, and I'm not
exactly small, if you know what I mean.
 
Hiro looked over at Tadashi's cock and nodded. He had to be 8 inches at least.
It would be a real stretch for Hiro's virgin hole.
 
"K-keep going, then."
 
Tadashi patted Hiro's knee with his unoccupied hand, and pushed his other
finger all the way in. He hit the back of his brother's hole, and felt a small
opening there, like a second asshole. His finger wasn't long enough to push
through it, but he knew that his goal would be to push something through there.
 
Tadashi pulled his finger most of the way out, then thrust it back in. He did
this a few more times. Then slowly added a second finger. He spread them apart,
stretching Hiro, and listened to the boy moan.
 
At long last, Tadashi decided Hiro was ready. He withdrew the fingers, and
climbed back on top of his brother. Tadashi leaned down to whisper in Hiro's
ear.
 
"You ready, genius?"
 
"Maybe. . . What about aunt Cass?"
 
"She went to bed a while ago. Besides, I locked the soundproof door that we
installed together last year" Tadashi winked. Hiro smiled, and Tadashi felt a
rush of emotion as the adorable gap in Hiro's teeth was exposed.
 
Their hard cocks were pushed together as Tadashi leaned forward and pressed his
lips gently onto Hiro's. The younger Hamada moaned, and melted into the kiss.
 
Tadashi moved his hips backwards, and began to position himself at Hiro's
entrance. He grabbed his cock with one hand, and guided it into place.
 
"I must advise you to use protection, Tadashi" came a calm, male voice from
behind them. Hiro jumped slightly with fright, and he and Tadashi turned their
heads to look at Baymax, who was staring at them blankly.
 
"Shit!" Tadashi muttered to Hiro, "I,d almost forgotten about him!" then "No
can do, Baymax."
 
The droid stared at him for a second, then continued thatkig. "I must insist.
Protection exists for a reason. Would you like me to list the risk factors of
unprotected sex?"
 
Tadashi frowned. "No thank you. Now, if you don't mind, I'm busy. I'm satisfied
with my care."
 
The bubble droid quickly deflated, and was sucked back into the metal suitcase.
While Baymax was now gone, though, the damage was done. Both boys were slowly
loosing their erections.
 
Hiro looked shyly up at Tadashi.
 
"I-I don't really think. . . I'm not in the. . . . Not that I don't still want
to do it with you. . . It's just . . . Awkward now."
 
Tadashi nodded in agreement. He wasn't feeling the sexual magic anymore either.
In fact, now that Baymax had killed the mood, he was starting to rethink his
actions of the past few minuets. What was he thinking, trying to fuck his
little brother? It was wrong! It was beyond wrong! It was. . . Arousing?
 
Just a soon as his horniness left, it came swooping back into Tadashi. The
wrongness I the situation, for some reason, made Tadashi feel more aroused.
 
But no, Hiro had said he'd had enough, and Tadashi had to respect that, no
matter how much he wanted to forget about Hiro's feelings, hold him down, and
screw him raw.
 
Tadashi let out a gasp of desire. He had to get his rocks off somehow, but not
here, and not now. Tadashi carefully sat up and rolled off of the bed. He stood
up, and looked down at his little brother's small, naked body. A shudder of
longing coursed through him, but he could see by Hiro's now flaccid cock that
his brother had not swung back around to horniness.
 
"Sure thing, l-little bro. Maybe another t-time?"
 
Hiro nodded, but said nothing. He pulled his bed sheets up over himself to
cover his nude form. Tadashi suddenly became painfully aware that his cock was
still rock hard, dripping with pre, and pointing directly at Hiro.
 
He hastily edged away from his brother, heading for the light switch by the
door.
 
"We should really get to bed. . . And if you want, I can turn off the light so
you can head back over to your bed?"
 
Hiro cleared his throat. "Umm. . . Yeah, yeah let's do that."
 
Tadashi frowned slightly, but snapped the light switch down just the same.
There was instantly a shuffling of feet as the room was thrown into darkness,
and Hiro tore across the room to his own bed.
 
Tadashi sighed inwardly, and headed back to his own bed. He would have to
ignore his raging erection, and try to get some sleep.
 
It had been a long night. The fact that Hiro would soon be going to school with
him, that they had just survived a fire, and that Tadashi had just lost one of
his main professors all seemed like they had happened weeks ago, not hours.
 
Then again, the reason why they felt less important now was a huge event in
itself. Tadashi had sucked his own little brother off! A fourteen year old
family member! And why did this only make it more appealing to Tadashi? He
didn't feel this way about any other children or family members, just Hiro.
 
With a sigh, Tadashi pushed those thoughts from his mind. It was late, and this
really wasn't helping his boner go away. He'd just have to ignore it for now.
 
Tadashi pulled up his blankets, rolled over, and closed his eyes. The last
naughty thought he let slip through before drifting off to sleep, was that
surely Hiro would want to have sex later? Now that he'd had a taste, he would
be craving more. And who did he have to come to in order to satisfy his needs
besides his older brother?

***** As My Heart Explodes (mini chapter) *****
Chapter Summary
     Quick mini chapter in which Tadashi engages in sexual activities with
     a sleeping Hiro
Chapter Notes
     Hey, I felt bad about not updating this in a while, and got bored in
     forensics, so here you go: a mini sex chapter!
Tadashi awoke drearily when a line of sunlight, which had slipped through a
part in the curtain over his window, crept up to his face.
 
He sat up, stretched, yawned, and blinked the fog out of his eyes. Tadashi sat
there for a minute, waking up. He soon became vaguely aware that he was naked.
 
This struck him as slightly odd. He never went to bed naked. Not when Hiro was
sharing a room with him, and might see Tadashi's privates. . .
 
And then he remembered. Hiro! And last night! The fire, Baymax, and then. . .
sex. . . or, almost sex. Tadashi had sucked off his little brother! He'd almost
fucked him, too. He'd had his fingers inside Hiro's asshole! But he hadn't
managed to go the whole way.
 
Tadashi felt himself harden. He let out a quiet gasp, and reached under the
covers, wrapping his hand around his hard member. He had participated in sexual
acts with his little brother! It was unbelievably, horribly wrong. . . But why
didn't he care? Why did Tadashi want more? Why did he want to find Hiro right
now, and fuck him till they both came?
 
Tadashi let go of his cock, and rolled out of bed. He crept across the room,
and approached Hiro's place of rest.
 
Hiro was still under the covers, fast asleep. He was on his side, facing the
door. What was more, Tadashi could tell by the way Hiro's white sheets clung to
his small form that Hiro was still naked.
 
Tadashi moaned and moved so that he was right next to the bed, facing his
brother's back. His hard cock was pointing straight at Hiro, like some sort if
sexual dowsing rod.
 
Tadashi leaned forward and gently eased himself onto the bed. Hiro didn't stir,
so Tadashi carefully lifted the covers that were wrapped around the boy.
 
Tadashi laid eyes on Hiro's small, naked form, smooth, hairless ass facing him,
and spread every so slightly open due to the position his was in. Tadashi could
also see Hiro's balls just beneath his ass. Tadashi let out another gasp, and
slowly slid under the sheet next to Hiro, and wrapped his arm around the boy's
midriff.
 
As Tadashi lowered the sheet down on top of both of them, he scooted forward so
that his naked body was spooning Hiro's. He felt his cock slide between Hiro's
ass cheeks, and moaned once more.
 
Hiro shuddered slightly, but didn't wake. Tadashi smiled, closed his eyes, and
moved his hand so that he was cupping Hiro's privates like a teddy bear.
 
Tadashi couldn't help himself. He started slowly humping into Hiro's ass
cheeks. He felt his foreskin sliding back and forth over his head, and panted
slightly as pleasure began to gently roll through him. He also felt pre leak
out of his tip and start making Hiro's ass wet.
 
With the hand that was cupping Hiro's genitals, Tadashi began pulling at his
younger brother's foreskin. He felt the young boy's head eagerly, and began to
push his own cock further between Hiro's cheeks, although he was careful to do
all if this slowly and gently, so as not to wake the boy.
 
Hiro's cock started to get hard. The boy stretched slightly, and let out a
single, low moan, but stayed fast asleep. With this new development, Tadashi
began to push all the way back, so that the head of his cock was striking
lightly against Hiro's asshole.
 
And as Hiro's cock became hard, Tadashi stopped playing with his foreskin, and
instead wrapped his hand around his little brother's cock, as began to slowly
Jack him off.
 
Tadashi's thrusts became more urgent. He knew he was close, even if Hiro
wasn't. Should he cum between he sleeping brother's ass? The idea seemed
appealing, but then again, Tadashi was horny, and probably not thinking
straight.
 
And then, suddenly, he didn't care. A massive wave of pleasure rushed through
him. Tadashi's back arched, and the rest of his body went rigid. His mouth
split into a silent "O", and he began to shoot thick streams of white, hot cum
into his brothers ass cheeks.
 
Tadashi's face broke into an ecstatic grin, and he thrust his cock forward
twice, milking it, doubling the pleasure, and getting everything wet and
sticky.
 
Tadashi's body slowly relaxed. His muscles unclenched, his back straightened
out, and and rested his head down onto Hiro's pillow. With a sigh if relief,
Tadashi closed his eyes.
 
It was a miracle that Hiro had slept through that. Even though Tadashi had gone
relatively slow as gentle, he knew that Hiro must've truly been exhausted to
not wake up during the fact. The fire at the university last night must've
taken more of a toll on Hiro than either of them had previously thought.
 
Tadashi felt himself starting to get soft once more. His cock was losing its
hardness, and was sliding slowly out of Hiro's sticky ass.
 
The eldest Hamada tried to stay awake. He wanted to enjoy the relaxed sexual
pleasures for as long as possible. It had not escaped his notice that Hiro's
cock was still rock hard, and Tadashi would've loved to have exploited that.
But he was unbelievably comfortable, and quickly fell into the soothing warm
darkness of sleep. That last thing he thought of before drifting away, was that
he would surely get to have more fun with Hiro when they both woke up.

Chapter Summary
     Tadashi coerces Hiro into having sex
Chapter Notes
     Hey guys! I hope you enjoy this chapter. I'm not really sure what to
     write next. I have one or two ideas, but nothing to solidly tie them
     into a new chapter, so is love it if you'd leave your suggestions in
     the comments, or else just let me know what you think of the fanfic
     so far
"TADASHI!!!"
 
With a jolt, the eldest Hamada awoke, staring blearily through squinted eyes
against the harsh light filtering in through the bedroom window. He became
fuzzily aware that he was naked, and not in his bed. He puzzled over this for a
moment before the memory of last night and early this morning came back to him.
 
"H-Hiro?"
 
Tadashi looked over at his younger brother, who was sitting up in his bed- the
same bed Tadashi was in- and was also naked. He was staring furiously at his
older brother, and had his bed sheet held up to his chest.
 
"T-Tadashi! Why are you s-sleeping with me?"
 
Tadashi scowled. "I just got turned on this morning, Hiro. Besides, you looked
so comfy. . . "
 
Hiro glared back at Tadashi.
 
"So you just decided to climb into bed with your naked little brother?"
 
"Well, I mean. . . Yeah."
 
Hiro rolled angerly out of bed and stormed over to his cabinet. Tadashi's
greedy eyes followed the naked form of his brother across the room. He really
wanted that ass.
 
"Hiro. . . I thought you wanted this too?" Tadashi said soothingly as he
watched Hiro wrench open his cabinet and pull on a pair of tight red underwear.
 
Tadashi stretched and sat up straighter. He was slightly puzzled by Hiro's
behavior. Had it not been the younger brother who had initiated sexual contact
between them last night? But now he was acting like it had never happened, and
as if Tadashi was some sort of creep for trying to follow through on what Hiro
had started.
 
Hiro turned around and faced Tadashi, who licked his lips nervously a the sight
of his little brother's bare arms, legs, and chest.
 
"I do want it, 'Dashi. Just not like this! Not first thing in the morning, not
all at once, and certainly not right after we've escaped from a fire where a
man died!"
 
Tadashi pushed himself out of bed too, purposefully letting Hiro see his
achingly hard cock. The older boy walked over to his much smart brother, and
took Hiro's hand in his.
 
"What if this is exactly what I need, though?" He asked quietly as he moved
their hands onto his hard member.
 
"What if I need my little brother's body to get me through these . . . Hard
times?"
 
Hiro closed his eyes and moaned softly. Tadashi looked down at him and was
happy to see a tent rising in Hiro's underwear. He reached down and placed his
hands under Hiro's waistband, and began to slowly push the underwear down.
 
"But . . . It's the middle of the day. . . " Hiro murmured, although he allowed
his underwear to be pushed down to a crumpled heap around his ankles, "isn't
this a nighttime thing?"
 
Tadashi's breath caught in his throat at he laid eyes on Hiro's hard,
uncircumcised penis.
 
"Not. . . Not necessarily." He said.
 
Tadashi grabbed Hiro's shoulders gently, and steered him back over to the bed.
He laid Hiro down on his stomach, spread his legs, and stared in awe at the
boy's tight, virgin asshole.
 
"Are. . . Are you sure, Tadashi?"
 
"What's there to not be sure about?" Tadashi chuckled.
 
"I mean. . . We're brothers. . . And I'm only 15."
 
"14", Tadashi corrected. Hiro scowled at this.
 
"I turn 15 in two months. It's close enough. And isn't 14 worse?"
 
Tadashi had actually given this a surprising amount of thought since last
night.
 
"Hiro, I don't care about it as long as you don't. I love you, okay, and I
don't want to make you uncomfortable. But we both want this, right?"
 
Hiro nodded slowly. Tadashi grinned and reached out to squeeze his brothers ass
gently. Hiro's breath caught in his throat.
 
Tadashi lowered his voice to a crooning, caring level. "So, it's alright with
you, then, sexy?"
 
Hiro moaned softly as Tadashi allowed a finger to slip into Hiro's ass crack.
The boy nodded, and Tadashi's face broke into a grin.
 
Tadashi leaned forward and whispered in Hiro's ear.
 
"Don't move a muscle. I need to get something from my cabinet."
 
Tadashi placed a kiss delicately onto Hiro's check, then moved off the bed and
crept across the room. When he reached his cabinet he opened it carefully and
removed a small packet of lube.
 
The eldest Hamada lept back across he room, tearing the packet open with his
teeth as he went. He bounded playfully onto the bed, and gazed lovingly at his
naked brother.
 
"Hiro, you're so damn sexy!" Tadashi murmured as he reached forward and traced
circles around his little brother's asshole with his index finger.
 
"You're pretty fine yourself." Hiro winked back before gasping at Tadashi's
touch.
 
Tadashi moaned with longing and squeezed out the packet of lube onto Hiro's
tight hole. He knew he should prepare Hiro with a finger or two, but Tadashi
was too horny to wait. He did as much as rubbing the lube in, and partially
inserting one finger for a few seconds, then moved so he was on top of Hiro's
small form, his hard cock pressed against the wet entrance to Hiro's ass.
 
"Hiro, this might hurt at first, but the pain won't last long. You understand?
And when it's gone, it should feel amazing."
 
"Just. . . just do it already!" Hiro panted, his eyes closed.
 
"I love you, genius."
 
"I love you too, nerd."
 
Tadashi grinned, then slowly began pushing inside Hiro. To Tadashi, it felt
like heaven. It was better than when he had fucked Go-Go long ago when they'd
first met! But Hiro gasped loudly, gritted his teeth, and scrunched up his
face.
 
"Oooohhhh God yes! It's OK, Hiro. It'll only hurt for a minute. And this feels
so fucking good to me!"
 
Hiro's breath came out in sharp bursts. It felt like someone was tearing his
abdomen open! But he held on, trusting in Tadashi. Although he couldn't help
clamping down tightly onto his brother's cock.
 
"It's. . . It's OK, T-Tadashi! I can take it! It's getting better. . ." Hiro
panted. He was arching his back slightly, even though Tadashi was hardly an
inch inside him.
 
And it really was getting better. The pain was beginning to fade away, and was
replaced by a strange yet pleasant feeling Hiro had never experienced before.
 
Tadashi pushed in another quarter of an inch. Hiro grunted, but nodded at his
brother, signaling that he was alright.
 
Tadashi's impulses screamed for him to give one giant thrust, to push all the
way inside his brother, but the need to make certain his Hiro was OK overrode
that impulse.
 
"F-fuck, 'Dashi!" Hiro gasped, squeezing his eyes shut. "That-that's. . .
Amazing!!!"
 
Tadashi grinned. He pushed in further and moaned.
 
"I kn-know, Hiro! It's really s-something else!"
 
With one final dedicated thrust, Tadashi managed to get all the way inside
Hiro. The older brother bit his lip, and added a tiny bit more lube from the
packet before throwing it aside and gripping the bedsheets tightly on either
side of Hiro's head.
 
Tadashi started to pull out slowly. Hiro's breath started coming out in sharp
pants, and Tadashi paused for a moment, but Hiro motioned for him to keep
going, and the older brother pulled out until only his head remained inside
Hiro.
 
With only a second's pause, Tadashi shoved the full length of his uncut cock
back into Hiro. Both boys let out loud moans of pleasure. Tadashi had evidently
hit Hiro's sweet spot.
 
Now that both boys were comfortable, and Hiro was adequately lubed up, Tadashi
fell into a rhythm of pushing his cock in, semi-slowly pulling it most of the
way back out, then sliding it squeltchily back inside Hiro's virgin hole.
 
Never before had Tadashi been this glad that he and Hiro had installed a
soundproof door. Both brother's loud moans were mixing together and echoing
around the room. Even with the door, Tadashi was amazed that aunt Cass couldn't
hear them fucking.
 
Hiro let out a loud "aaaahhhhhh!" With every thrust of Tadashi's cock, and
Tadashi was mirroring this with nearly every movement, although admittedly he
wasn't as loud.
 
The eldest Hamada started to thrust faster. Hiro's moans grew in intensity
steadily along with Tadashi's thrusts, but the boy gave no sign of discomfort.
 
"Ooooohhhhh, fuck, Hiro! Y-you're so t-tight!"
 
"That's. . . That's g-good, right?" Hiro panted, tongue lolling out slightly.
 
Tadashi nodded. "Yeah, it's r-really good!"
 
Tadashi's balls started slapping against Hiro's every time Tadashi's cock
pushed in. It added a rhythmic smack smack smack to the sex noises already
filling the room.
 
Hiro could feel his brother strike his sweet spot with nearly every thrust,
giving the underage boy the kind of extreme pleasure he had never felt before.
Hiro lost himself in the pleasure, and laid on the bed like a rag-doll, mouth
open, eyes glazed.
 
Tadashi was beginning to feel a buildup in his lower gut. An increasingly large
wave of pleasure was steadily coursing through him.
 
"H-Hiro! I think I'm gonna c-cum!"
 
Hiro knew what that meant, but had never seen or experienced it. And right now,
he didn't particularly care.
 
Hiro swallowed, then shakily gasped "d-do it!"
 
Tadashi started groaning loudly. "Ah! Aaahh! Ahhhh!! Fuck yes!! Ahhhh! Hiro!"
 
With a final thrust of his hard cock deep into his brother's asshole, Tadashi
started shooting his massive, hot, sticky load.
 
"AAAAAHHHHHHH! Fuck yes!" Cried Tadashi as a look of ecstasy crossed his face.
He felt his cock twitch and contract hard as it kept shooting, filling up
Hiro's ass.
 
When finally Tadashi ceased cumming, he was hit by a wave of exhaustion. He
pulled squeltchily out of Hiro with a sound like a wet suction cup. He watched
as white fluid spilled out of Hiro's gaping hole onto the bed. Tadashi caught a
strong whiff of a chlorine-like smell.
 
Tadashi collapsed on his back next to Hiro, who looked at him stunned.
 
"'D-Dashi. . . That was amazing!"
 
Tadashi grinned drearily. "Fuck yeah it was! I'm sorry you didn't cum, little
bro. I'll make sure you do n-n-n-next t-time" Tadashi gave a huge yawn. Though
he'd just slept for nearly 12 hours, he could feel himself beginning to fade
into sleep again.
 
Hiro rolled over and embraced Tadashi, snuggling up close. Tadashi could feel
Hiro's hard cock pressing into his side.
 
The older brother grinned, and slowly ran his fingers through Hiro's hair.
 
"I love you, Hiro. I'm just going to take a short nap, ok? Can you wake me in
half an hour?"
 
Hiro smiled innocently and nodded.
 
"Sure thing, 'Dashi. I love you too. Sweet dreams."
 
Tadashi's final thought before he drifted off was that surely this is what
perfection was. For he was perfectly happy, and he knew Hiro was too.
***** Experimentation *****
Chapter Summary
     Hiro fears that Tadashi won't want to fuck again, so he gets Baymax
     to finger him while Tadashi is supposedly in the shower. Meanwhile,
     aunt Cass tells Tadashi he needs to keep an eye on Hiro for a while
     longer before taking a shower, resulting in Tadashi walking in on
     Hiro and Baymax "playing"
HIRO JERKED AWAKE AT THE SOUND OF A KNOCK coming from the door to his and
Tadashi's room.
 
"Hiro! Tadashi! Hello?" Came aunt Cass's voice through the speaker Tadashi had
installed in the ceiling that enabled he and Hiro to hear what people outside
their door were saying.
 
Tadashi groaned and sat up bleary-eyed. He stretched and let out a long yawn,
then glanced over at his little brother with a sly smile. Hiro's heart thumped
hard in his chest.
 
"Boys? I know you can hear me!" Cass called. "You've slept clear through the
day, which is good... You definitely needed to sleep after what happened last
night..."
 
Hiro and Tadashi jumped upright, staring at each other in bewilderment. They'd
slept all day?! Well, not all day, but....
 
Their heads zipped around to look out the nearest window. Sure enough, they
could see a dark purple evening sky.
 
"Anyway, I made dinner. Well,
When I say 'made' I mean 'went to the fast food chicken wing place down the
street and bought some greasy fried stuff for us to munch on'. So get dressed
and come downstairs, alright. You need to eat, and I don't want you getting
your days and nights turned around!"
 
Silence fell in the room once more. Hiro gazed over at his brother, who was
still stretching an yawning. It was hard for Hiro to believe that only a few
hours ago, Tadashi had been inside him! And now they were just going to act
like nothing happened until the next time they were both horny? It didn't feel
right to Hiro.
 
But Tadashi quickly proved him wrong. He stopped stretching, and gave Hiro a
warm smile. "Hey there, genius. Rise and shine!" Tadashi stretched out a hand
and ruffled Hiro's hair, then pulled him ino a brief but loving kiss.
 
Hiro's eyes widened and he moaned softly. Tadashi pulled away, smiled again,
then rolled out of bed and stood up, giving Hiro a vivid show of his whole
body. Tadashi walked quickly over to his side of the room, opened his cabinet,
as started to get dressed.
 
"C'mon, Hiro. You better get dressed too. We shouldn't have gone back to bed,
and aunt Cass is right, we need to eat something!" Tadashi pulled on a pair of
blue jeans and looked concernedly over at Hiro, who was still in his bed and
under the covers.
 
"Yeah, yeah, I'm coming!" Hiro groaned, and he too rolled out of bed. Tadashi
let out a wolf whistle, then started laughing, which brought a smile to Hiro's
blushing face.
 
"Come here often?" Hiro called to Tadashi as he bent over to pick up the
underwear he'd tried to put on earlier that day, but had quickly discarded when
Tadashi had talked him into fucking.
 
Tadashi's breath caught in his throat as he laid eyes on Hiro's asshole and
balls. Hiro stood back up with a grin, and slowly began to pull on the
underwear. He was happy to see a tent rise in his older brother's pants.
 
"Like what you see, Nii-San?" Hiro winked slyly across the room at his brother.
 
"What's with all the cheesy pickup lines?" Tadashi chucked as he pulled on a
red t-shirt. "You know I'm yours already, so do you really need them?"
 
"Eeeehhh, what can I say? I'm in a good mood". Hiro turned around and opened
his clothes cabinet, pulling out a pair of shorts before looking back at
Tadashi.
 
"We survived a major fire less than 24 hours ago! Am I really that good in
bed?"
 
"Well, to me you are. But then, you are my first," Hiro chortled and put on his
shorts, "so I really don't have anything to compare it to".
 
Tadashi laughed. "Alright, genius. Hurry up and get your shirt on. I'm
starving!"
 
Hiro waved aside Tadashi's words, and picked out a periodic table shirt. "We
should make our beds before we go downstairs. We may have just been through a
tragedy, but I'm pretty sure Cass won't let us skip our chores...."
 
Tadashi sighed deeply. "Yeah, I know. Make it quick."
 
Hiro stepped back up to his bed, grabbed the sheets, and was about to pull them
back up near the headboard when he caught sight of something and let out a
gasp.
 
"Shit!"
 
Tadashi peeked his head around his divider. "What's up?"
 
Hiro but his lip "Uuuhhh... We might need to wash this..."
 
"Huh? Wash what for why?" Tadashi walked over to Hiro's bed and gazed at the
problem. "Ah... Yyyeeeeaaaahhhhh, that's going to be difficult...."
 
The two boys were looking at the side of the bed Hiro had been sleeping on the
last few hours. A large, wet stain had spread across the sheets there.
Evidently, while Hiro was sleeping, all of Tadashi's cum had seeped out of
Hiro's asshole and into the bedding.
 
"Ummm... We'll take care of that later, Hiro, ok? Let's.... let's go eat
first."
 
Hiro nodded. "Alright. How do we sneak it past Cass, though? She's, like,
obsessed with laundry".
 
"Leave that to me. Come on, let's go get some chicken! I wasn't joking about
being hungry, you know".
 
-------------------------------------------------------------------------------
-----
 
"Hiro, honey, slow down! You do want to taste the chicken, don't you?"
 
Hiro froze with a massive mouthful of poultry. "Sshary, aunt Cath!" He grunted,
then quickly chewed and swallowed. Tadashi chuckled lightly from across the
table, then tore into a drumstick.
 
Hiro wiped the grease off his hands and onto a napkin, then reached for his
last breast.
 
"Gah, you boys are just devouring you dinner tonight! Is it that good, or are
you just that hungry?" Cass asked, waving a drumstick of her own through the
air.
 
"Both!" Hiro and Tadashi chorused in unison.
 
"Take it easier next time" aunt Cass laughed. "These poor chickens didn't die
so they wouldn't be enjoyed!"
 
Hiro and Tadashi slowed down somewhat as they ate their last pieces of fried
chicken. Tadashi put the drumstick in his mouth and winked at Hiro while aunt
Cass was distracted trying to keep their fat cat from jumping on the table.
 
Hiro picked out and ate the last pieces of meat from his breast, then leaned
back in his chair. "Aaaahhhh that was delicious! Thanks a ton, aunt Cass".
 
"Oh, you're welcome. It wasn't any trouble. You've been through quite an
ordeal. I'm just trying to help".
 
"But still, thank you," Tadashi smiled, "I think we're going to be OK, though.
May we be excused? We're kinda working upstairs.... Seeing what we can salvage
from Hiro's microbots after the fire...."
 
Cass nodded at them both. "Yes, of course. Go on. Just.... Don't start any more
fires, ok?"
 
Hiro grinned. "Don't worry, we'll be careful". The two boys stood up and ran
back up the stairs towards their room.
 
"Alright, I'll take this down to the washing machine," Tadashi said once they
were safely back in their room, and he started pulling the soiled sheet off
Hiro's bed, "and you stay here. I think I'll also take another shower while I'm
down there. I got kinda sweaty earlier when we were.... You know...."
 
Hiro nodded as Tadashi started walking to the door with an armful of bedding.
"And, eerr, what am I supposed to do until you get back?"
 
Tadashi shrugged. "I mean, I hardly showed you any of what Baymax can do. You
could always tinker with him?"
 
Hiro nodded. "Yeah, I might do that. Anyways, see ya later, nerd!"
 
"See ya later, genius" Tadashi called, and he walked out of the room, kicking
the door closed.
 
Hiro let out a bored sigh and fell down on his sheetless bed, thinking. It had
felt so good when Tadashi had fucked him earlier that day. So good, and so
wrong but the wrongness of it was starting to appeal to Hiro now. He wanted to
feel it again. To feel someone inside him!
 
Except he wasn't sure if Tadashi would want to do it again so soon! Not that it
wasn't clear his big brother love him, but Hiro didn't know Tadashi to be the
kind of guy who indulged himself more than once a week. . . .
 
But if not Tadashi, then who?! Or.... What? Hiro grinned slyly and sat back up,
casting his eyes around for any phallic objects he might be able to use.
Tadashi wouldn't be back for at least 25 minutes, so surely Hiro could figure
something out?!
 
But his heart quickly sank. He didn't see anything that looked like it could
comfortably be used as a dildo. And even if he did find something, he had no
more lube... Well, that he knew of. Maybe he should just forget it and play
with Baymax like Tadashi had suggested?
 
And then Hiro sat up even straighter, a glint in his eye. aha!, he thought in
triumph, I know exactly how to get what I want!
 
"Ow!" Hiro said loudly. And from over on Tadashi's side of the room, there came
the sound of rushing air. A moment later it stopped, and the white, bubbly body
of Baymax was shuffling across the room towards Hiro.
 
"Hello, I am Baymax, your personal healthcare companion" said the droid in its
reassuring robotic voice as it stopped at the foot of Hiro's bed. "I was
activated when my audio sensors heard you say 'ow'," Baymax held up his right
pointer finger. "How may I be of assistance?"
 
Hiro crawled across the bed, a grin on his face, and he began to feverishly
unbutton his shorts. "Yeah, I'm ok, Baymax. But I was wondering... Are you
equipped to perform Rectal Examinations?"
 
-------------------------------------------------------------------------------
-----
 
Tadashi had barely entered the laundry room when Cass swooped in behind him.
 
"Hi, honey! Is that laundry? I can take care of it if you want? You know how
peculiar our washer is. I'm the only one who seems to know how to control it."
 
Tadashi's face turned red. "Ummm, no thanks, aunt Cass. I think I've got it".
 
"Oh, come on, Tadashi! You don't want to accidentally ruin your bedding, do
you?"
 
He swallowed and inched closer to the washer. "A-actually, it's Hiro's
bedding".
 
Cass frowned. "What on earth did Hiro do to his bedding? I just washed it the
day before yesterday! He didn't have a nightmare about the fire and wet the
bed, did he? I thought he was a bit old for that now".
 
Tadashi blushed deeply. "No! No, it's not that!"
 
Aunt Cass smiled. "Ok, then. Here, jut let me do this for you" she reached a
hand toward the bundle of sheets Tadashi was holding. "Whatever it is, I'll
figure out how to best wash it".
 
"No!" Tadashi cried, and he tugged the sheets out of her reach. "You can't
touch it!"
 
Cass narrowed her eyes. "And Why's that?"
 
Tadashi could hear his heart thumping. "B-because.... We were
experimenting...."
 
"Experimenting?" Cass asked. "Like, experimenting with each other?"
 
Tadashi nearly choked. "Wh-what?!"
 
"You know, like a science experiment you two were doing together?"
 
A wave of relief rushed through Tadashi. "Oh... Yeah! And we, Uuuhhh,
accidentally spilled a chemical on his sheets!"
 
Cass sniffed. "Hmmm it does smell kinda like chlorine. Alright, put it in the
machine. I won't touch it. But I'm setting the cycle for you!"
 
Tadashi nodded, and carefully put the sheets in the laundry machine, his heart
racing. Cass took over from there, fiddling with various knobs and buttons.
After a momet, she turned back to Tadashi, smiling.
 
"Oki, that should do it! Now you head back upstairs and take care of your
brother".
 
"Actually, Cass... I was gonna take another shower. I got pretty sweaty in my
sleep earlier".
 
"You'll do no such thing!" Cass scowled. "Your little brother is probably still
playing with those chemicals he spilled on his bed. And he needs a companion
after what happened with the fire and all. That was a traumatizing experience,
and I don't wanna have to pay for therapy because his older brother would
rather take a shower than spend time with him. You go make sure he's safe.
After that you can have your shower".
 
Tadashi nodded in shocked agreement and turned to head back to his room. He was
just glad Cass hadn't found the cum stains.
 
Tadashi trumped back up the stairs with a sigh. Maybe he and Hiro could find
something fun to do to pass the time? He could show Hiro Baymax's
defibrillators, maybe? Or they could skip Baymax altogether and watch porn?
 
The eldest Hamada trudged back up the stairs. He paused for a moment outside
the bedroom door, then pushed inside.
 
"Oooohhhh! Y-yeah!" Hiro's moans reached Tadashi's ears and he froze.
 
"Is this examination satisfactory?" Came Baymax's voice. Tadashi quickly shut
and locked the door, then walked further into the room and gasped loudly.
 
Hiro was on his sheetless bed, completely naked, on his hands and knees.
Tadashi felt himself start to go stiff at the sight. But that wasn't all. Hiro
was masturbating slowly, and Baymax was leaning forwards with one finger pushed
inside Hiro's asshole!
 
"Hiro! What the hell are you doing?!"
 
The young boy jumped in surprise, pulling himself loose from Baymax's finger,
which Tadashi was glad to see had shrunk to accommodate the tight space it had
just been occupying.
 
"T-Tadashi! I thought you were taking a shower! I didn't expect you to get back
until I- we- were done!"
 
The boy was blushing furiously, but made no attempt to cover himself. Tadashi
resisted the urge to moan at the sight of Hiro's small hand wrapped around his
hard cock.
 
"Cass wanted me to keep an eye on you for a while before showering. Ummm... How
and why did you get Baymax to fuck you? That's not what he's supposed to be
used for! And you do realize that I'm head over heels for you, right? I'd
gladly have sex with you whenever you want".
 
Hiro blushed even deeper. "Well.... When you say it like that.... I just
thought that since we'd just done it, and had to change the sheets because of
it, you wouldn't want to do it again yet. So I asked Baymax for a Rectal
Examination".
 
Tadashi blinked in surprise. Not only was he impressed that Hiro had figured
out how to fuck himself so effectively, but he was also pleased Hiro truly
wanted more of his older brother. Something hungry and lustful rose up inside
the older Hamada. If Hiro wanted sex, it was his job to provide it.
 
Tadashi grinned and started unbuttoning his pants. "Baymax, Hiro's satisfied
with his care". The marshmallow droid walked awkwardly back across the room and
was sucked back down into his suitcase-like charging station.
 
Tadashi walked towards the bed, discarding bits of clothing along the way. Hiro
moaned as his brother's muscular chest and legs were revealed.
 
"Why on earth wouldn't I want to fuck you again?" Tadashi asked softly.
 
"Well, you always restrict how often you do stuff for yourself. One candy bar a
week, hardly ever using the TV to watch your own shows. . . I thought you'd
want to wait a while".
 
Tadashi laughed. "Hiro, this is something for both of us, not just me!" He
rubbed the tent in his crotch slowly. "And besides, how could I resist you and
that delicious ass that comes with you?" Tadashi licked his lips.
 
"C'mon, nii-san! We don't have all night!" Hiro chuckled in relief. "Well, OK,
I guess we do... But still, get over here!"
 
Tadashi laughed. "Patience is a virtue, little genius" he nonetheless tore off
his underwear and bounded onto the bed. "Then again, we're not exactly about to
be virtuous, are we?"
 
Hiro smiled lovingly and reached up to cup his brothers warm face. "Shut up and
kiss me, nerd!" He whispered. Tadashi complied eagerly, and their lips met.
Tadashi's were somewhat rough and chapped, but Hiro's were soft, smooth, and
perfect. Tadashi groaned and pushed Hiro down onto the bed.
 
Hiro moaned softly and reached down to grab hold of Tadashi's large dick. The
older boy grunted slightly, but continued making out with the smaller boy
underneath him.
 
Hiro slowly started to paw Tadashi off, pulling his foreskin up and down over
the head of his cock, which caused Tadashi to gasp loudly, and Hiro to grin
widely.
 
"Like that, big bro?" Hiro muttered evilly. Tadashi closed his eyes and nodded
vigorously. "Isn't it so much better when someone else masturbates for you?
Especially family" Hiro grinned wider and increased his grip on Tadashi's hard
member.
 
"H-Hiro... wait.... This isn't f-fair" Tadashi moaned, and he reached down to
grab Hiro's wrist. The younger boy frowned.
 
"C'mon, 'Dashi! Let me do this for you!"
 
It took all of Tadashi's willpower to not lay back and let Hiro work his magic.
But he knew he couldn't do that. "Hiro, I've already used you to please myself
without returning the favor once. I can't do it twice in a row. You didn't cum
last time because I was too exhausted to make it happen. I won't deny that to
you again. Plus, I wanna be the one who causes your first ejaculation. I don't
want you to find that pleasure out alone in some bathroom, or with Baymax!"
 
Hiro blushed heavily and looked away. He wanted to make Tadashi happy, but he
wanted to feel that pleasure too. His cock gave a hungry twitch, and Hiro made
up his mind. He brought his hand back up to he's chest, and laid down fully.
 
"Alright.... But it's your turn next time!"
 
Tadashi grinned, then crawled down towards the foot of the bed so that his face
was inches away from Hiro's cock. "Don't worry. I fully intend on cumming
tonight too. Now, let's give this another shot, shall we?"
 
Hiro groaned lustfully. "Just hurry up, nerd!"
 
Tadashi nodded and grabbed hold of Hiro's cock, pointing it slightly downwards
towards his mouth. He gave it a swift lick that caused Hiro to squirm and groan
loudly.
 
Tadadhi grinned, then pushed the head into his mouth. He started licking it
like one would a lollipop, swirling his tongue around, lapping at the delicious
part at the end of the stick.
 
Hiro cried out with pleasure and grabbed onto Tadadhi's head with one shaking
hand. "Aaahhh fuck!" The younger Hamada groaned. Hiro sat up slowly, and moved
carefully so as to not cause his brother to stop sucking him off, and got on
his knees.
 
Tadashi grinned and his eyes flashed up to meet Hiro's gaze. He then slipped
his tongue beneath his little brother's foreskin, where he knew the pleasure
would best be generated.
 
At this point, Hiro's whole body was shaking. He moaned softly and began to
thrust gently into Tadashi's mouth. The older boy grunted and sucked his cheeks
in slightly, causing the pleasure to gently increase.
 
As Tadashi sucked and Hiro thrusted, the younger boy reached over towards his
bedside table and pressed a button that he knew would cause his bedside
security camera turn on.
 
He had originally installed the small, HD camera that tracked movement as a way
to see if Tadashi had messed with his stuff. The two boys had grown up pranking
each other, so safety between their various projects had never been guaranteed.
But Tadashi using his own mouth to bring Hiro to his first climax.... Well,
that was a memory the youngest Hamada never wanted to forget.
 
And Hiro could feel his foreskin sliding back and forth over the head of his
cock. He could feel Tadashi's tongue working on the more sensitive areas,
slipping in and out of his little brother's slit. And he could feel a tug- some
unfamiliar buildup of pleasure- rising in his stomach and his crotch.
 
"Wh-what...!?" Hiro groaned, closing his eyes. Tadashi ignored him and kept
blowing.
 
Hiro couldn't exactly explain the feeling. He'd never experienced it before.
But it kept growing larger and larger, and getting more and more pleasing. Soon
enough, Hiro was moaning, gasping and grunting uncontrollably!
 
Tadashi grinned slightly, and reached up, sliding two fingers between Hiro's
ass cheeks, and up into his hole, which was still loose from Baymax.
 
Hiro cried out once more in pleasure and arched his back slightly. The buildup
in his stomach was becoming a bubble ready to burst.
 
And as Tadashi began to thrust his fingers into Hiro, that bubble did burst!
Hiro felt the pleasure suddenly spread to the tips of his fingers as something
rushed out of his cock.
 
The younger boy howled loudly as he started to cum hard into his brothers
mouth. The hot, sticky liquid shot down Tadashi's throat, and the boy quickly
pulled himself off of Hiro's cock, keeping his mouth open so he could see as
well as taste Hiro's very first ejaculation. At the same time, Tadashi
liberated his fingers from their short excursion inside Hiro, but the younger
of the two brothers didn't notice the change.
 
The pleasure was beyond anything Hiro had ever felt before. He whimpered and
tugged at Tadashi's hair until his cock was done shooting its load, then the
boy fell back onto the bed in a dazed heap, grinning like a fool.
 
Tadashi's smirking face, which was covered in cum, appeared in Hiro's vision.
"Way to go, genius!" He said proudly as he ruffled Hiro's hair. "That was
amazing! Quite the load too".
 
"Mmnnnn... It f-felt wonderful!" Hiro said dreamily. "I can't believe I'd never
done it before!"
 
Tadashi nodded, and climbed on top of his little brother, pinning his arms over
his head (not that they needed restraining).
 
"Ready to return the favor for me, my little nerd?" Tadashi asked as he kicked
Hiro's legs open softly. Hiro nodded and spread his legs wider for his brother.
"Anytime, Nii-San".
 
Tadashi carefully positioned himself, pressing against Hiro's asshole. "Gods, I
love you so fucking much, little bro!" Tadashi murmured as he began to push
inside.
 
His breath smelled like cum. It was a very tantalizing scent to Hiro, who began
grunting again as Tadashi re-stretched his hole.
 
Hiro lifted his head up as much as he could, and pressed his lips against
Tadashi's. His brother responded passionately, pushing his tongue into Hiro's
mouth as he shoved his cock down Hiro's ass.
 
Hiro tasted his own cum in Tadashi's mouth and moaned even more. It felt so
naughty to him, to taste his own manhood. Especially on his own brother. And
this served only to make him more horny.
 
As Tadashi started thrusting slowly and deeply into Hiro, their balls pressing
together momentarily before separating for several seconds, Hiro pulled out of
the kiss, and started to lap and suck his own cum off his brother's face.
 
It wasn't long before Hiro had collected every drop. Tadashi smiled and started
to suck on Hiro's neck as his brother licked his lips in satisfaction.
 
"Aaahh that feels amazing, Nii-San!" Hiro moaned as Tadashi nibbled lightly at
his brothers skin before resuming his sucking. Tadashi's cock started pumping
harder into Hiro, striking his sweet spot with every other thrust and causing
Hiro to grunt loudly.
 
Tadashi pushed forward with his hips and felt his cock dive deep inside Hiro.
The wet pressure from the walls of Hiro's ass felt perfect. Tadashi's own slice
of heaven. He knew he couldn't hold back for long.
 
"T-Tadashi!" Hiro gasped his brother's name aloud, his mouth hanging open
slightly. "Oh, f-fuck! You're in so deep!"
 
The older brother gritted his teeth as he continued thrusting. The swell of
pleasure had already begun, and Tadashi knew he was close, but he wanted to
make it last as long as he could.
 
But Hiro kept moaning Tadashi's name and clenching his ass around Tadashi's
cock. Even as Tadashi slowed down to give him more time inside his little
brother, Hiro was touching himself, moaning, and sucking on Tadashi's shoulder
at the same time Tadashi was biting Hiro's neck.
 
"H-Hiro! You're gonna m-make me~" Tadashi stammered, but Hiro silenced him by
biting down lightly on Tadashi's shoulder.
 
"Aaahhhh! F-fuck!" Tadashi groaned quietly. And before he knew it, he was
climaxing. He let out a much louder gasp and started to fill Hiro's asshole
with his hot cum.
 
Hiro felt Tadashi start to ejalculate into him, and let out a small gasp
himself. Tadashi kept thrusting, even while nutting deep inside his little
brother, causing some of his cum to spill out onto the bed.
 
Each thrust brought Tadashi so much pleasure that his vision blurred. It was
almost too much for him to take. But he kept going, determined to feel
everything until the last drop was squeezed out.
 
Hiro gripped Tadashi's arms tightly until the older boy stopped cumming, and
slumped forward, exhausted. Hiro wrapped his arms around his brother, and
rested his hands on the boy's ass.
 
"Fuck, Hiro, that was outstanding!!!" Tadashi gasped, then kissed his brother's
cheek. Hiro blushed and smiled to himself.
 
"I'm gonna stay here a moment to rest, but then we've gotta go get cleaned up",
Tadashi continued, and he started circling Hiro's left nipple with his thumb.
 
"But if you want... We could go get a shower together? Aunt Cass is too
preoccupied to notice".
 
Hiro nodded. "Definitely! I need to take one anyway. Might as well do it with
my lover". Hiro brought one of his hands up to the middle of Tadashi's back.
 
Tadashi smiled at him, then rested his head on Hiro's shoulder. "We'll go soon,
love. But for now, this is exactly where I want to be".
