by RL4r
Summary
     Age Swap!AU
     Hiro tests his big, upcoming invention (ie his microbots) one day and
     ends up fracturing his ankle and his forearm. In consequence, Hiro is
     stuck in bed, away from his lab and his beloved work. As the days of
     his recovery period slowly pass, Hiro quickly gets bored and
     frustrated, and poor Tadashi, his darling younger brother, is on the
     receiving end of his restlessness. When enough becomes enough,
     Tadashi knew that he’d have to take matters into his own hands.
     Or perhaps it was more appropriate to say, “take matters into his own
     mouth”, because that was kind of what actually happened.
Notes
     Oh my god, I can’t believe I actually went through with writing
     this…*blushes furiously* I have officially earned my one-way ticket
     to hell. Oh well.
     So what really inspired this exactly? Nothing really. I was just in
     desperate need of more Age Swap AU fics (particularly of the smutty
     variety LAWLLLL) and well, I guess I’ve always wanted to try writing
     a blowjob. This is my first time writing about one by the way
     lawlllll So excuse me if it’s hardly sensual. xDD I think I have a
     kink for writing unsensual sex LMFAO (wow that’s SOOOOO STRANGE).
     Sorry for plaguing this fandom with it…
     The thing is, I didn’t get an opportunity to write one for my FWP
     series (it just didn’t quite fit into the mood of the story or even
     the smut draft I HAVE managed to write for that matter, so I was
     missing out on practicing how to write it), so I guess it’s for the
     best that I made a separate two-shot story for it. I don’t want to
     spoil too much of the second part, but the second part will have
     Tadashi assuming a more bottom role…which is what I had actually
     wanted to write in the first place, yet there is no bottom Tadashi in
     this particular chapter of the two-shot. *cries* That feel when you
     fail at the ONE JOB you had set out for yourself from the very
     beginning…how embarrassing.
     So all in all, this is just self-exploratory and self-indulgent
     trash. Aha… please forgive me orz Not really beta-d or as proof-read
     as my FWP installment (because really, I need to get myself away from
     this smuttiness before I explode hahahaa) so, please excuse any
     glaring grammatical or spelling errors!! >_

***** Part One *****
            
               My Darling Brother (What would I do without you?)
 
            Hiro Hamada was a nation-renowned robotics genius and a bright
rising star in the health-informatics-and-technology field...
...Who happened to be sedated on a plain old hospital bed, located in some far-
off corner of the San Fransokyo Hospital’s huge Emergency Department. Pain
killers, especially the strong kind, tended to do that to you. But what in the
world would have warranted the use of pain killers in this guy?
 
            Well, Hiro was involved in a little bit of an accident earlier that
day. He had been testing out a brand new invention at his lab; the invention
was tentatively called, “Microbots”. One of the functions of said invention was
transportation, including transportation of people. As such, Hiro was using the
microbots to move himself around.
 
            The microbots should have been strong enough to hold Hiro up,
whether he was standing upright or upside-down. It just so happened that as he
was using the microbots to scale across the ceiling of his lab, the wiring of
his invention decided to fail on him.
 
            The result of the malfunction was that Hiro suffered a pretty bad
fall, one that resulted in the fracture of his ankle and his arm on his left
side. The fall also caused the destruction of equipment worth a couple of
hundreds of dollars (but who cared about that anyway). Luckily, his aunt
(affectionately called “Aunt Cass”), who had been his caretaker since he was
about 10 years old, had plans to pick him up at his lab that particular
afternoon to go out for lunch. She happened to arrive shortly after the whole
incident happened and promptly called for an ambulance. The rest of the story
was pretty much self-explanatory.
 
            Ok, so testing a new invention in such a dangerous way probably
wasn’t the most logical or smart thing to do (man Professor Callaghan was going
to KILL him when he found out). But hey, the science world was VERY unkind to
slow work; robotics and health-informatics were highly competitive fields, and
there was no way Hiro was going to allow anyone to push forth something like
his invention before he did. His own health be damned!
 
            But anyway, long story short, the reason why Hiro was currently
heavily sedated and pretty unresponsive was because he had injured himself.
Otherwise, he wasn’t too bad off at the very moment, relatively speaking.
 
            Much to the relief of his one other beloved family member besides
his aunt: his younger brother Tadashi.
 
            Aunt Cass had texted Tadashi when Hiro’s condition had stabilized;
Tadashi was just finishing up his last class of the day by then. Upon reading
the message, he wasted no time in bolting out of his high school and hoping on
the next bus that passed by the hospital. Needless to say, Tadashi was worried
sick about his older brother, whom he always respectfully (and affectionately)
addressed as “Nii-san”.
 
            The Hamada brothers shared a very deep bond with one another;
Tadashi figured that part of it stemmed from the fact that they had lost both
their parents at such a young age. Even though Aunt Cass was the best guardian
either of them could have ever asked for, Tadashi had never felt the same way
about Aunt Cass as he did about Hiro (and he was sure Hiro felt the same way).
Hiro understood him on a spiritual level, and he was the one person that
Tadashi knew would never judge him and would always listen to him, no matter
how dark or murky things got.
 
            Well, perhaps it was easy to say all of that now, following
Tadashi’s confession of his feelings for Hiro to Hiro and Hiro happily
accepting Tadashi’s confession because he felt the same way about Tadashi.
Wait, what?
 
            Hiro and Tadashi were very close (that had already been
established), but not only in a brotherly way. Tadashi came to realize that he
had romantic and sexual feelings for his older brother when he was a little
over 13 years old; needless to say, he spent most of his early teenage years
quite confused and distressed, forever fearful that his older brother would be
disgusted with his feelings. But the mental and emotional stress of hiding his
secret became too much one fateful day and Tadashi finally came clean to his
brother. To his immense relief (and surprise), Hiro not only accepted his
feelings but also told him that he returned them. Similar to Tadashi, Hiro had
feared that Tadashi would be disgusted with him if he had ever known Hiro’s
true feelings for him, so he had held everything inside for years. Needless to
say, years of pent-up tears were shed that night by the both of them; Tadashi
could never forget the fact that their first kiss together tasted salty because
they had been crying so much. But it’s worth mentioning that it was still very
enjoyable anyway.
 
            It was all something that Tadashi had never anticipated happening,
not even in his wildest (and darkest for that matter) dreams. But for better or
for worse, they were technically together now. Needless to say, they kept their
relationship secret from everyone; it made their love life, among other things,
quite tough, but Tadashi figured that as long as he had Hiro and Hiro had him,
they’d make do with what they had.
 
            After what felt like forever, the bus Tadashi was on finally
stopped at the hospital. Tadashi darted off and headed straight for the
entrance into the Emergency Room; he found Hiro and Aunt Cass shortly after he
entered the large ward. To Tadashi’s slight dismay, Hiro was still kind of out
of it and didn’t seem aware of his presence; still, Tadashi settled on simply
holding his older brother’s good hand in his own, forever grateful for the fact
that Hiro was alive. Banged up for sure, but alive.
 
            Sometime around 8 PM, the doctors in the emergency room decided
that it’d be for the best if Hiro was to be admitted into the hospital, even if
it was to be only one or two days. Aunt Cass had no specific reason to disagree
with the doctors; Tadashi admittedly didn’t want to be separated from his
beloved older brother (they had been rooming together since forever), but if it
meant a faster recovery, he’d deal with being alone at night for a few days.
After they completed all the necessary paperwork for Hiro’s admission and got
the visiting hours for the hospital, Hiro was transferred up to one of the
inpatient floors while Aunt Cass drove Tadashi and herself home. Tadashi
anxiously waited for the next time he’d be able to see Hiro again.
 
            It turned out that most of Hiro’s first day in the hospital was
spent getting scans done and mild surgical procedures done, so Aunt Cass told
Tadashi to not bother going to the hospital that day (which was a Tuesday).
Tadashi was saddened by the news, but he did as he was told, spending the
afternoon after school doing his homework and catching up on his studies. To
his relief, when Aunt Cass came home that night, she happily told him that Hiro
should be ready to leave the hospital by tomorrow evening and that Tadashi
could visit him in the afternoon. She gave Tadashi the instructions on how to
get to Hiro’s room from the hospital lobby on a piece of paper after dinner;
Tadashi kept said piece of paper in the pocket of his favorite blazer, close to
his heart.   
 
            And so, Tadashi eagerly headed to the hospital after school the
next day (which was a Wednesday) to see his brother. He followed Aunt Cass’
carefully written instructions and had no problem finding Hiro’s room. Hiro
was, to his relief, fully awake this time around, and when he made eye contact
with his little brother, his face erupted into a wide smile, one that revealed
his trademark tooth gap.
 
            “Dashi! You came!” Hiro exclaimed happily. He moved his good arm
out, silently asking for a hug. Tadashi had to use all of his willpower to stop
himself from jumping into Hiro’s arms (because that would hurt his older
brother even more and he didn’t want that); he carefully settled down on the
bed before he wrapped his arms around Hiro’s back and rested his face against
Hiro’s chest.
 
             It had barely been two days, but Tadashi felt like it had been
forever since he had been able to be with his brother. When Tadashi sniffed a
little against his older brother’s hospital gown due to his raging emotions,
Hiro soothingly rubbed his hair in understanding. Hiro had really missed
Tadashi too. 
 
            The two conversed for hours before Hiro’s doctor came by to discuss
Hiro’s discharge from the hospital and all of his scheduled physical therapy
appointments. The plan was for Hiro to be in a wheelchair for the majority of
his recovery period; he was also given crutches to use if he had to ambulate
himself to go to the bathroom or something. When the doctor discussed exactly
how long it was going to take for Hiro to fully recover, Hiro’s face
practically fell to the floor: his arm and ankle were going to take atleast 6
weeks to fully heal. That was a long time for an aspiring inventor to be away
from his lab!
 
            “My poor poor Nii-san…” Tadashi whispered, gently stroking Hiro’s
forehead. The news could’ve been way worse, but Hiro had never been one to look
at things from a positive angle.
 
            “The next couple of weeks are going to be tortuous…” Hiro groaned
unhappily. “Can I just keep myself knocked out with the pain killers all the
time? It might make things easier.”
 
            “Now now Mr. Hamada, I understand how frustrating it must be for a
young man like yourself to be bed-ridden for most of the day. However, if you
take your medications as directedand may I stress, only as directed…and if you
follow up with your physical therapy appointments, you’ll be as good as new
soon enough. You think you can do this for me?” Dr. Hannah asked.
 
            “Yeah sure thing Doc.” Hiro said half-heartedly. Tadashi clicked
his tongue at his brother’s attitude.
 
            “I’m sorry Dr. Hannah…my older brother doesn’t mean to be rude or
anything…he’s just…he has a lot on his mind right now.” Tadashi explained
hurriedly, embarrassed on his brother’s behalf. Dr. Hannah chuckled good-
naturedly.
 
            “That’s quite alright Mr. Hamada. I understand. It’s one thing to
be sick when you’re getting on in your years and another thing to be sick when
you’re still quite young. Considering how smart your older brother is, it must
be even worse. I don’t take his words personally, don’t worry.”
 
            “Thank you Dr. Hannah.” Tadashi said, smiling up at the doctor.
 
            “Sure thing,” Dr. Hannah said, patting Tadashi’s shoulder gently.
“I’m glad that he has such a caring and smart younger brother to be there for
him. You’ll help him with his medications and appointments right? Make sure he
doesn’t overdose on anything ok? You know how dangerous that could be.”
 
            “You bet!”
 
            “Glad to hear. I just need to finish up some last minute paper work
and you guys can go home alright? Take it easy until then.” Dr. Hannah said
before he left the two brothers alone. Tadashi promptly gave Aunt Cass a call
to let her know that she should come pick them up soon before he sat back down
on the bed.
 
            “Nii-san…you shouldn’t be so rude to your doctor while you’re in
the hospital…” Tadashi chided gently. Hiro grumbled in response.
 
            “Don’t you find him patronizing? Hmph.”
 
            “No, not really to be honest…Dr. Hannah is very nice and
understanding in my opinion…”
 
            “Is that why you smiled at him? Is that why you let him pat your
shoulder? Man I’m telling you, he looked ready to pat your head too. He’s so
lucky that he didn’t or I would’ve flipped. I don’t appreciate anyone doing
that to my little bro…except me.”
 
            Tadashi blinked at Hiro before promptly erupting into soft giggles.
 
            “Oh Nii-san, why are you jealous over something like that? C’mon,
are you REALLY telling me that you’re jealous of Dr. Hannah? That guy is
clearly married and probably almost has grandkids for Pete’s sake. He has no
interest in getting to know me knucklehead. Or perhaps you’re just picking a
fight to keep yourself entertained?”
 
            “…Maybe…” Hiro said as he averted his eyes. Ever since they had
gotten together, Tadashi had gotten increasingly better at reading him like a
book. It was almost scary.  
 
            “Does Mr. Grumpy face want a snack? I’ll run down to the cafeteria
to get you some gummy bears if you behave and stop being so rude to the medical
staff.” Tadashi cooed. Hiro’s eyes sparkled in response.
 
            “Would you really do that?”
 
            “Of course! Anything for my nii-san.” Tadashi said sweetly, patting
Hiro’s head affectionately. Hiro was just so adorable when he got jealous and
grumpy like this; Tadashi would’ve kissed his brother on the cheek as well, but
they were in public, so Tadashi restrained himself. The last thing the two
needed was a nurse or someone to give them questioning looks. With one last
loving glance at his brother, Tadashi exited the room to go get Hiro his
promised snack.
 
            Aunt Cass arrived at the hospital just in time to pick up her two
nephews, much to both Tadashi’s and Hiro’s relief (Hiro just wanted to get the
hell out of the hospital already). It took awhile for Tadashi to gather all of
Hiro’s stuff into the trunk and for everyone to safely get into the van, but
when the trio finally managed to all get inside, they happily made their way
back home. When Hiro entered the Lucky Cat Café, the first thing he did was
clumsily dig into one of the café shelves and extract a doughnut. Both Aunt
Cass and Tadashi gave him questioning looks.
 
            “What? Do you have any idea how disgusting hospital food is? I’m
starving.” Hiro said before promptly tearing the doughnut to shreds.
 
            “Oh my goodness. Uh…I’ll start making dinner right away dear,” Aunt
Cass said, nervously glancing at how fast Hiro was eating. “How about you go on
upstairs to your room? I’ll bring everything upstairs when it’s ready.”
 
            Hiro looked up the stairs that took him up to the floor he shared
with Tadashi. They had never looked so intimidating in his recent memory.
 
            “Man I really could use the help of my microbots right about
now….these stairs are going to be killer…” Hiro groaned.
 
            “Weren’t those small things the reason you got this way in the
first place? C’mon Nii-san, I’ll help you upstairs no problem,” Tadashi said.
“Forget about your microbots.”
 
            “Heh. Thanks kiddo.”
 
            It took a good solid 10 minutes for the two to make it up the
stairs; Hiro had never been so glad to see his bed in his whole life. With a
little help from Tadashi, he was able to change into some clean clothes and lay
down on said bed comfortably. Hiro sighed deeply as Tadashi fluffed up his
pillow.
 
            “Man, I’m not going to be able to move around much like this, am
I…” Hiro whispered. He sounded exhausted, and Tadashi’s heart clenched
painfully in consequence.
 
            “I’ll be here whenever I can be Nii-san. Please don’t get too
disheartened,” Tadashi said gently, finally kissing Hiro on his cheek for the
first time in days. “I’ll be your arms and legs for as long as you’ll need.”
 
            “Mmm…thanks Tadashi. I’m sorry about all this.”
 
            “That’s alright Nii-san…”
 
            Their conversation was interrupted by the sounds of Aunt Cass
climbing up the stairs to their floor; it turned out that Aunt Cass had made
them some delicious fried rice and steamed bok choy for dinner. After setting
everything up on Hiro’s bed, Aunt Cass went back downstairs to fetch some basic
necessities (a big water pitcher and some snacks in case Hiro needed something
between meals) for her injured nephew. Meanwhile, Tadashi happily began to feed
Hiro his food.
 
            “I can do it myself…” Hiro had insisted after the first bite. But
Tadashi wasn’t having it.
 
            “You’re tired from climbing the stairs and weak from not eating
enough for the past couple of days. Please, just let me help you. I’m your arms
and legs now remember?”
 
            “Yeah, I remember,” Hiro replied softly. “And alright…if it’s what
you want.”
 
            The two brothers finished dinner sometime around 9; Hiro definitely
looked ready to go to bed afterwards, so Tadashi quickly cleaned up all the
dishes and utensils and brought everything downstairs. After Tadashi put all
the used dishes in the sink, he took one of Aunt Cass’ mixing bowls from her
cabinet (he’d buy her a new one if she asked) and brought it upstairs, figuring
that Hiro probably wouldn’t have the strength to make it to the bathroom to
brush his teeth. But what Tadashi could do was bring all the necessary tools to
Hiro’s bed and use the mixing bowl as a make-shift sink.
 
            Hiro appreciated the gesture, and with Tadashi’s help, managed to
brush his teeth and wash his face. After Tadashi got all of that cleaned up and
dutifully returned to Hiro’s side, Hiro shifted over slightly on his bed and
gestured for Tadashi to sit down.
 
            “Care to sleep with me tonight to make up for lost time?” Hiro
asked.
 
            Tadashi wanted to, more than anything, but he hesitated briefly.
 
            “Wouldn’t it be better if you gave yourself more room to sleep?”
 
            “Nah,” Hiro said. “To be honest I haven’t been sleeping well at all
without you. C’mon, sleep with me. It’ll be fine.”
 
            “Ok…if you insist.”
 
            “Goodnight kiss?” Hiro asked as Tadashi curled up against him.
 
            “Always.” Tadashi whispered, leaning in to chastely kiss Hiro on
the lips.
 
             It turned out that the both of them were in for rough night
though. For one reason or another, Hiro’s ankle and arm started greatly
bothering him in the middle of the night; Hiro tried to ignore the pain at
first, but after about an hour or so of doing so, it eventually grew to be too
much. Hiro hated having to wake up Tadashi, but he needed a dose of his pain
meds and there was no way he could get them for himself right now; after
groaning tiredly into his hand for a good 10 seconds, Hiro gently shook Tadashi
awake. It was admittedly unpleasant to be woken up in the middle of the night,
but Tadashi successfully managed to give Hiro his pain medication and Hiro’s
pain eventually ebbed away, much to his relief. While Hiro sort of dozed off,
once again slightly sedated from his narcotic medications, Tadashi laid awake
in bed, worry clawing at his stomach. If every day and every night was going to
be like this for the next couple of weeks, this was all going to be harder than
he thought wasn’t it?
 
            Still, life went on no matter how many struggles one faced. You
just had to make the most of it.
 
            Aunt Cass and Tadashi took turns taking care of Hiro while he was,
for the most part, bedridden; Aunt Cass would tend to Hiro in the morning while
Tadashi would tend to Hiro in the afternoon and evening. On Aunt Cass’ end, she
decided to pay two of her workers overtime to help her with the morning shift
so that she could have more time to check up on Hiro. On Tadashi’s end, he
dutifully went straight home every day after classes to tend to his healing
older brother, skipping all of his afterschool extracurricular activities and
social events in the process. Tadashi was forever grateful that his teachers
and friends had all been very understanding of his current family circumstances
and didn’t hold anything against him for being unable to perform his school
duties.
 
            But despite Tadashi’s and Aunt Cass’ valiant efforts, Hiro grew
more and more restless and frustrated as the week slowly passed by; Tadashi
could see it in his eyes. And there was absolutely nothing more dangerous than
a bored and frustrated Hiro, as Tadashi knew all too well from their younger
days. But what could Tadashi do? Hiro needed to rest, Aunt Cass needed to work,
and Tadashi needed to go to school. As much as he would’ve liked to, Tadashi
couldn’t play hooky to entertain his brother at home.
 
            The worst part of it all was that Hiro was still in quite a lot of
pain; he tried his best to not be irritable because of it, but he was,
sometimes snapping at both Aunt Cass and Tadashi over the smallest of things.
In Tadashi’s case, he actually had it worse, because he spent more time with
his brother than Aunt Cass did; still, Tadashi knew that Hiro didn’t truly mean
it and was always very patient with him. It was still emotionally draining at
times though.
           
            Tadashi really hated seeing the hopelessness and distress in his
older brother’s eyes and hearing his frustration in every word he spoke
throughout the day. He knew he had to do something to relieve some of Hiro’s
distress soon, or his beloved older brother really might hurt himself or do
something drastic.  
 
            His opportunity came Saturday afternoon when Aunt Cass had to make
one of her special deliveries to a client that lived outside the city. The
drive was going to take a good couple of hours, so Aunt Cass didn’t expect to
return home until the early morning hours. Before she left, she explained to
Tadashi that she had dinner saved for both him and Hiro in the kitchen and that
he didn’t have to worry about closing the café (she was closing early). Tadashi
felt slightly guilty at being happy over the fact that Aunt Cass was leaving,
but he knew that it was for the best. This way, he could definitely help his
older brother get some much needed de-stressing.
 
            Tadashi made sure he saw Aunt Cass’ van disappear into the distance
before making his way upstairs to get their dinner ready. Dinner was a quiet
affair; Tadashi dutifully fed Hiro like he had been doing the past couple of
days. After cleaning everything up, Tadashi asked Hiro if he wanted to change
his clothes.
 
            “Sure. Get me a new shirt please?” Hiro requested. Tadashi quickly
complied.
 
            Tadashi then slowly helped Hiro out of his shirt, but he didn’t
move to replace it. Hiro looked at Tadashi, slightly concerned.
 
            “Uh…Tadashi…are you ok?”
 
            “Yeah…”
 
            “Then can you help me put on my shirt please? It’s a little cold.”
 
            To Hiro’s slight surprise, Tadashi suddenly climbed up onto his bed
and straddled his lap, all the while gazing into Hiro’s eyes. Hiro flushed
slightly.
 
            “Um…”
 
            “Aunt Cass isn’t here tonight…” Tadashi whispered as he wrapped his
thin arms around Hiro’s shoulders; Hiro’s eyes widened in understanding.
 
            “…I see.” Hiro replied, guiding Tadashi’s face closer to his with
his good hand. His lips were but a few centimeters away from Tadashi’s when he
stopped.
 
            “Want me to touch you?” Tadashi whispered.
 
            “Please…” Hiro replied, all thoughts about getting a new shirt on
himself forgotten.
 
            Tadashi’s hands worked swiftly and skillfully, touching all along
Hiro’s chest and his abdomen. On Hiro’s end, he kissed all over Tadashi’s ears
and his neck, leaving some light bites along the way. He was careful to never
make any lasting marks though, lest Aunt Cass or anyone else got suspicious.
The two then shared a couple of deep passionate kisses, their tongues hungrily
exploring every last inch of the other’s mouth. When the two broke apart to
catch their breath, Tadashi could feel Hiro’s growing erection against the
inside of his thigh. Good.
           
            Tadashi crawled down Hiro’s body and tentatively kissed his older
brother’s growing erection through his boxers. Hiro instantly hissed in
response.
 
            “W-what are you doing?”
 
            “…I’m going to suck you off.” Tadashi said, almost matter-of-
factly.
 
            “What? No, Dashi no.” Hiro said, covering himself with his good
hand and attempting to nudge Tadashi off of him with his good leg. Tadashi
couldn’t help but roll his eyes.
 
            “Calm down you big baby and let me just…do this for you!” Tadashi
declared loudly, gripping Hiro’s hips, much to the shock of Hiro.   
 
            “No, Tadashi…please…I don’t want to hurt you.” Hiro begged, though
his body quivered underneath Tadashi’s hands in anticipation. Tadashi sighed
softly before lifting himself up from between Hiro’s legs to straddle Hiro’s
lap once again. He then began stroking Hiro’s hair gently, not unlike how Hiro
often did to him when he needed something to soothe him.
 
            Hiro was scared for Tadashi because of their past experiences with
oral sex; Tadashi remembered what his last experience with giving his older
brother a blowjob was like, very well in fact. To be quite honest, it wasn’t
exactly a pleasant memory (Tadashi’s throat and jaw were sore for days
afterwards). However, Tadashi had had just about enough of his nii-san’s
distressed behavior over the past week, and he figured that this would be the
best way to get rid of some of his restlessness (besides, practice made perfect
right?). He knew that Hiro needed this; heck, maybe even Tadashi needed this.
It had been a long, frustrating week after all.   
 
            “I’m older now and more experienced than I was before Nii-san.
Besides, are you really going to disagree with me that you haven’t been bored
out of your mind the past week and that you need to de-stress a little?”
 
            Hiro looked away briefly, his eyes filled with guilt. Tadashi
couldn’t help but giggle fondly at his older brother’s petulant expression.
Sometimes he wondered who exactly was the older one in their relationship.
 
            “We have the house to ourselves…we can be as loud as we want for a
change.” Tadashi whispered huskily in Hiro’s ear, playfully tempting him. Hiro
scoffed.
 
            “Whatever ever happened to my sweet, innocent little brother?” Hiro
said, pouting a little. It was all in jest though, because they had done some
pretty dirty things together. Both of them were hardly innocent, not by a long-
shot.
 
            “You give me way too much credit; I’ve never been a perfect angel.
Anyway, are you going to let me do this for you or not?” Tadashi asked, more
gently this time. “It’ll be safer than having penetrative sex because your body
is still healing.”
 
            Hiro hid his face behind his one good hand for a moment before
nodding briefly. He knew he had lost the battle.
 
            “Fine…just…don’t hurt yourself ok kiddo?”  
           
            “Yeah yeah…I’ll be careful.”
 
            Tadashi kissed Hiro on the lips one last time before moving himself
off the bed and repositioning himself in-between Hiro’s legs. He was glad to
discover that at his current height (in comparison to his height a month or so
ago), he was able to comfortably rest his elbows against the mattress, making
it much easier for him to hold down Hiro’s hips if he needed to during the
whole process. With a nod from Hiro, Tadashi pulled off Hiro’s boxers,
revealing his half-hard erection; after taking in a deep calming breath and
wetting his lips, Tadashi took the very tip of his older brother’s erection
into his mouth.
 
            Tadashi took a few seconds to adjust to the sensation before he
started slowly swirling his tongue around the tip while stroking the base with
both of his hands. Tadashi kept his eyes closed at first, simply enjoying the
sound of Hiro’s soft moans and the feel of Hiro’s hand tangling in his hair.
After a couple of seconds, Tadashi opened his eyes to gaze up at his brother,
gauging his reaction. He was pleased to see that Hiro seemed to be having a
pleasant time; Hiro’s face wasn’t as tense as before and his upper body, on a
whole, definitely seemed more relaxed. Smiling in his head, Tadashi briefly
released Hiro’s now fully-hard cock from his mouth before sliding his tongue
slowly along the underside of it. He did this a couple of times before
returning to the tip, playfully holding it between his lips and teasing the
slit with his tongue as he stared at Hiro. Hiro could only look away to hide
his embarrassed face, seeing as one of his hands was held up in a sling while
the other one was deeply tangled in Tadashi’s hair.
 
            “Mmh…Don’t look at my face…” Hiro groaned quietly.
 
            “Why Nii-san? You look beautiful.” Tadashi whispered, taking a
brief moment to catch his breath.
 
            “…”
 
            “Nii-san’s so cute when he’s all embarrassed~.”
 
            “S-stop it!” Hiro tried to glare, but couldn’t quite manage to in
his current state. Tadashi laughed in consequence.
 
            “Are you going to punish me?” Tadashi whispered as he gazed into
Hiro’s eyes. In some small distant part of his brain, Tadashi felt slightly
embarrassed at his own words, but seeing Hiro slowly unravel before him was
definitely overriding said sense of embarrassment. Was Hiro going to say yes?
 
            “Oh god this can’t be happening…” Hiro moaned to himself. This side
of Tadashi was, admittedly, greatly turning him on, but he was supposed to be
the adult here! Damn his injured arm and leg for putting him in a position like
this!
 
            “It’s ok…just relax.” Tadashi said, and that was the only warning
Hiro got before Tadashi tried taking him in all at once, moaning the whole time
he went down his length.
 
            “…Mn…Ahh!” Hiro had to bite down on his bottom lip to stop himself
from screaming.
 
            Tadashi briefly stopped when he was a little more than half-way
down Hiro’s cock, his gag reflex kicking in and preventing him from going
further until he adjusted to the feeling; after a couple of seconds, he inched
further down. Despite the fact that tears were starting to dot his eyes and
blur his vision (it was admittedly getting a little painful for him, no matter
how good he knew it must have felt for Hiro), Tadashi did his best to lap at
the base with his tongue while also breathing through his nose. At this point,
Tadashi was starting to really taste and feel Hiro’s pre-cum in his mouth too,
further complicating the situation (it wasn’t that the taste was unpleasant per
say, but it just made his mouth feel all the more overwhelmed); still, he
vigilantly continued his ministrations, mixing in a couple of sucks with his
licks, knowing that it was all making Hiro feel good. If I didn’t love my nii-
san as much as I do, I wouldn’t be able to do this Tadashi thought absent-
mindedly.
 
            Inevitably, Hiro started thrusting his hips upwards into Tadashi’s
mouth, his body instinctively seeking the pleasurable heat of it; even though
Tadashi was able to hold down Hiro’s hips a little with his elbows, it still
hurt his throat the deeper Hiro pushed inside it. He wasn’t going to last much
longer at this rate (his jaw was killing him and his lips were swollen), but
then again, judging by the way Hiro’s legs were trembling beneath him and how
much Hiro was gasping from pleasure, Tadashi figured that Hiro was nearing his
limit too. He was going to stick this through if it was the last thing he did.
 
            With the last bit of his sanity, Hiro tried pushing Tadashi off his
cock with his hand because he didn’t want his little brother to swallow his
release; he knew that it’d hurt and that Tadashi would choke. However, not only
did Tadashi swat his hand away, he actually sucked and licked even harder,
driving Hiro further and further towards the edge.
 
            “Mmph…Dashi….I can’t…let go!”Hiro pleaded breathlessly. Although
Tadashi’s vision was blurred from his own tears and thus couldn’t see his older
brother’s desperate face and his taut abdomen, he could feel just how close
Hiro was to his limit from his practically pulsating cock. But his mind was
dead set on finishing this, so he simply didn’t let up (hey, he was in his
stubborn teenage years after all); with the last of his strength, he groaned
loudly, sending pleasurable vibrations down Hiro’s length.
 
            That did it. Hiro came with a low scream. Tadashi had been prepared
for it, but it still hurt when Hiro released himself into his throat and mouth.
He really did end up gagging and choking a little.
 
            Despite how hard he tried to keep his mouth over Hiro’s cock and
swallow Hiro’s release, Tadashi couldn’t help but fully retract his mouth, his
body in desperate need for oxygen that his nose just couldn’t supply and his
gag-reflex in full gear; in consequence, a mixture of saliva and semen poured
out from his mouth and onto his hand, getting all over his chin and neck.
Tadashi’s senses were on overdrive: he could feel the insides of his mouth
quivering (from pain or pleasure he couldn’t really tell) and still feel Hiro’s
cock against his tongue. The slightly bitter taste of Hiro overwhelmed him a
little, but he didn’t find it particularly strange or disgusting; he was just a
little embarrassed by how much of a mess his face must have been at the moment
(after all, he had been crying too). In addition, Tadashi’s heart was beating
so fast that he could practically hear it in his ears; Tadashi almost didn’t
feel like himself, but he supposed that his brain would right itself when his
lungs managed to get him more oxygen.
 
            A minute or so passed before he felt a warm hand gently stroke his
now sweaty hair. Blinking away tears, Tadashi looked up at Hiro, who was
smiling tenderly at him. Despite the fact that his jaw and throat were sore and
his efforts left his whole body feeling like jelly, Tadashi somehow managed to
climb back into his nii-san’s lap. Hiro wasted no time in kissing all over
Tadashi’s neck and face, cleaning him up a little along the way; finally, Hiro
captured Tadashi’s lips in a deep kiss, extracting some of his own release from
him and easing the quivering in Tadashi’s mouth with his skillful tongue.
Tadashi’s eyes fluttered close at the feeling of Hiro’s tongue against his own;
it was a pleasant change of pace from what he had had in his mouth a few
minutes prior.
 
            Then Hiro pulled away. Tadashi opened his eyes to see Hiro gently
wiping his chin with the shirt he had taken off earlier.
 
            “Are you ok kiddo?” Hiro asked softly. He let go of the shirt and
then used his free hand to wipe the last of Tadashi’s tears from the corner of
his eyes.
 
            Tadashi blinked a couple of times before nodding slowly. His throat
was so sore that he wanted to avoid speaking if he could.
 
            “You shouldn’t have hurt yourself trying to make me feel good
but…thank you. I’ll make you some warm honey tea to help your throat ok? Then
we can both shower and wash up.”
 
            Tadashi smiled softly before enveloping his brother in a tight hug.
Despite how immature Hiro could get, at the end of the day, Hiro always took
care of him when Tadashi needed it the most (it was this part of Hiro that
Tadashi was the most fond of). And boy did his throat really need some tender
loving care right now.
 
            “Actually…hold that thought…”
 
            Hiro’s hand travelled down Tadashi’s chest to his pants; Tadashi
shivered and moaned softly when Hiro pressed his hand against his clothed
erection.
 
            “Let’s take care of this first…”
 
            It was only fair Tadashi supposed. Sucking Hiro off had given him
some degree of pleasure, but it was more work than it was relaxation on his own
end. His body was still in need of its own release.
 
            But he refused to have his older brother exert himself (the last
thing he wanted to do was delay Hiro’s scheduled recovery), so Hiro simply
lathered Tadashi’s nape and ears with hot wet kisses while Tadashi jerked
himself off in his brother’s lap. It didn’t take long for Tadashi to achieve
his own much needed orgasm (after all, he wasn’t exactly trying to purposefully
hold it in) and for him to collapse against his older brother’s chest,
breathing rapidly. Much to Tadashi’s embarrassment, Hiro took his still-shaky
hand and licked some of his semen from his fingers.
 
            “H-hey, don’t do that!” Tadashi couldn’t help but whisper shyly.
 
            “It’s only fair I get a taste of you right? Besides, it’s only a
bunch of small cells, some proteolytic enzymes and natural sugars. It’s not a
big deal.”
 
            “….” Tadashi couldn’t really dispute that. Still he flushed a deep
red as his older brother’s tongue darted between his fingers.
 
            The two shared another deep, loving kiss before they got off of bed
together. True to his word, Hiro quickly made some soothing honey tea for
Tadashi (Aunt Cass had wisely left an electronic water boiler on his desk a few
days ago and had provided tea and coffee mixes along with it); despite the fact
that Tadashi’s throat still hurt a little after he finished the tea, he
definitely felt a lot better. He’d probably feel all better by tomorrow
afternoon if he drank some more tea in the morning.
           
            The two then cleaned up in the shower before pulling off the dirty-
top sheet from Hiro’s bed and wrapping it up. Tadashi dutifully put the dirtied
bed-sheet into his hamper (he’d wash it first thing the following morning)
before he made sure to put a new, clean one on Hiro’s bed. Hiro waited quietly
in his wheelchair while Tadashi got everything set up. When Hiro settled in and
got comfortable in his bed again, Tadashi crawled in next to him, careful to
curl up against Hiro’s uninjured side. The moment Tadashi nestled his head into
one of Hiro’s pillows, Hiro started stroking his hair.
 
            “Tired Dashi?” Hiro asked softly.
 
            “Mmhm.” Tadashi replied, closing his eyes. He was really glad he
didn’t have school tomorrow.
 
            “I love you kiddo. So much,” Hiro said, leaning over to kiss
Tadashi softly on the cheek. Tadashi giggled in response. “Thank you. I don’t
know what I ever did to deserve you.”
 
            “I love you too Nii-san,” Tadashi whispered happily. “But this is
kind of unlike you…when did you get so sappy?”
 
            “…But it’s the truth isn’t it? I’ve been so angry and awful these
past couple of days while you’ve been nothing but helpful. I’m really sorry.”
 
            Tadashi blinked away sleep for a brief moment, gazing up at Hiro,
who was wearing a sad expression. After a second or two of processing Hiro’s
words, Tadashi smiled a tender smile. It was something Tadashi had known all
along, but he appreciated Hiro formally apologizing nonetheless.
 
            “Thank you Nii-san. I accept your apology and I forgive you. I
think Aunt Cass deserves an apology too. Can you give her one as well
tomorrow?”
 
            “Sure thing.” Hiro promised.  
 
            “Ok then. Goodnight Nii-san.” Tadashi said before once again
closing his eyes.
 
            “Sweet dreams Dashi.” Hiro whispered tenderly.
 
            Tadashi easily drifted off to sleep, exhausted from the week and
from all the hard work he did in the past hour. On Hiro’s end, he stayed awake
for awhile, simply enjoying Tadashi’s quiet company and seeing Tadashi’s
adorable sleeping face. But eventually, the need to sleep consumed him, and
Hiro fell into a deep peaceful sleep.
 
            It was the first good night’s sleep he had had in a long time.

            It had been about 3 weeks after Hiro had his little accident in the
lab; in terms of recovery, Hiro was making good progress. Upon his most recent
physical therapy visit, the doctor informed him that he’d still need to keep
his arm in a cast, but at the very least he didn’t need to keep it in a sling
anymore; needless to say, Hiro was thrilled. In terms of his foot, he would
still need his wheelchair, but the doctor suspected that he would make a full
recovery as long as he didn’t do anything strenuous; all in all, Hiro still
wasn’t back to full functionality, but he was at least steadily getting there.
 
            Thus, Tadashi firmly insisted on being Hiro’s “arms and legs” for a
little while longer; considering how much Hiro loved having Tadashi dote on him
(yes he was a spoiled man), he simply let Tadashi continue taking care of him.
Thus Tadashi still helped Hiro change his clothes, fed Hiro meals, and fetched
Hiro things when he came back from school on the weekdays and all day when
Tadashi was home on the weekends.
 
            Speaking of fetching things…
 
            It happened to be a quiet Saturday evening (Aunt Cass was out again
doing special deliveries) and the Hamada brothers had just finished eating
dinner together about 15 minutes prior. Like many nights before, Tadashi was
curled up next to Hiro on his bed; Hiro was checking emails and messages on his
phone while Tadashi was studying one of his calculus textbooks. A comfortable
silence hung between the two as they busied themselves with doing their own
thing.
 
            That is, until Hiro grew tired of reading emails and the like and
decided that he wanted to read something intellectual of his own; Hiro nudged
Tadashi with his good foot to get his attention.
 
            “Mmm…what is it Nii-san?” Tadashi asked, turning his attention away
from his studies immediately.
 
            “Can you please get me one of my books from my shelf above my
computer desk?” Hiro asked.
 
            “Sure. Which one do you want?”
 
          “I want my robotics book but I don’t remember exactly where I left it
so…I’ll guide you when you get there.”
 
            Tadashi got off the bed and made his way over to Hiro’s desk.
 
            “It should be somewhere on the left of the shelf.” Hiro called to
Tadashi. Tadashi glanced at the books and noticed that there were actually two
robotics books.
 
            “There are two robotics books Nii-san…do you want ‘Callaghan-
Catmull Spline’ or ‘Callaghan’s Laws of Robotics’?” Tadashi asked.
 
            “Oh sorry about that…I forgot that I got another robotics book
recently…get me the ‘Law of Robotics’ one please.”
 
            “Ok.”
 
            Tadashi grabbed the book from the shelf and made his way back to
the bed to give the book to Hiro. Just as Tadashi settled back down and started
reading his calculus book again, he felt Hiro nudge him again.
 
            “Actually Dashi…I want both books. I’m so sorry… can you please get
me the other one too?” Hiro asked, his cheeks reddening slightly.
 
            “Nii-san…” Tadashi whined softly, but he got up anyway and went to
the bookshelf once more. Of course he’d change his mind and want both the
minute I lay back down, of course Tadashi thought, rolling his eyes as he
grabbed the book.
 
            Tadashi couldn’t help but sigh fondly though; he has been with his
brother for forever and well, he was quite used to this sort of behavior by now
(it was almost as endearing as it was annoying). Besides, he was the one that
kept answering every one of Hiro’s bratty demands, so he really only had
himself to blame anyway.
 
            “Here you go.”
 
            “Thanks kiddo.”
 
            “Don’t I get a kiss for all my hard work?” Tadashi joked lightly.
 
            “Of course! Come over here.” Hiro replied, patting his lap. Tadashi
eagerly settled on top of his older brother’s lap and awaited his kiss. Hiro
tenderly cupped Tadashi’s cheek before leaning in and capturing his lips in a
short chaste kiss.
 
            Tadashi shouldn’t have been surprised when Hiro closed the distance
between them again, his kisses this time less sweet and innocent. Tadashi
didn’t particularly mind though, as he always enjoyed Hiro’s kisses, chaste or
not; he tilted his head so that Hiro would have an easier time alternating
between sucking his upper lip and nibbling on his bottom one.
            “Nii-san…” Tadashi whispered as they briefly broke apart for air.
 
            “What is it Dashi?” Hiro whispered back just as softly.
 
            “Are you going to use that tongue of yours or not?”
 
            Tadashi could see Hiro’s Adam’s apple bobble up and down as he
chuckled.
 
            “I thought you’d never ask.”
 
            Hiro’s tongue slowly entered Tadashi’s awaiting mouth, exploring
every inch of it for what was probably the hundredth time. Tadashi was
pleasantly surprised when Hiro withdrew a little and allowed Tadashi to enter
his mouth instead; right when Tadashi was about to pull away, Hiro used his
lips to gently suck on Tadashi’s tongue, eliciting a soft moan.
 
            The two broke apart for air once again before Hiro started kissing
Tadashi along his neck and massaging his back. Tadashi groaned appreciatively
when Hiro gave his neck a particularly hot and wet kiss.
 
            “Mmm….”
 
            “You like that?”
 
            “…Yes…”
 
            Hiro smirked before slowly moving to kiss Tadashi’s ears; Tadashi
visibly shivered in response (his ears had always been super sensitive).
 
            “Hey kiddo…you want to have some fun tonight?” Hiro whispered
huskily in Tadashi’s ear.
 
            “I need to study…” Tadashi whined half-heartedly as he wrapped his
arms around Hiro’s neck, pulling Hiro closer to him.
 
            “That’s not what your body seems to be saying.” Hiro replied
cheekily as he started nibbling Tadashi’s ear.
 
            “Needed to say it…to make myself feel better about
procrastinating…you know how it is…”
 
            “Don’t worry Dashi…if you’re really worried, I’ll help you study
tomorrow. Promise.”
 
            Tadashi blushed slightly and it wasn’t because of the kisses and
nibbles that Hiro was lathering on his ear.
 
            “Really? You’d do that?” Tadashi asked disbelievingly, butterflies
erupting pleasantly in his stomach. Hiro almost never offered Tadashi help with
his academic studies (not that Tadashi had ever really needed it because he was
bright for his age but the thought was still nice) and high school calculus
would probably bore Hiro to tears.
 
            “Yeah sure,” Hiro replied easily, smiling a loving smile. “I care
about you doing well in school Dashi. Of course I’ll help you if you really
need me to.”
 
            “…Thank you Nii-san.”
 
            “No problem. Now can we have sex already?”
 
            “You’re unbelievable,” But Tadashi made no move to stop Hiro from
stripping himself of his clothes or stripping Tadashi of his right after. “But
I have to say, sex is more enjoyable than studying calculus.”
 
            “Obviously…” Hiro replied with a snort, massaging Tadashi’s lean
abdomen.
 
            “But you’re still injured…”
 
            “That’s ok. We can try different positions that won’t put as much
pressure on my back or leg. I’ve got it all figured out.” Hiro assured, patting
Tadashi’s head.
 
            “Clearly you know how to spend your time.”
 
            “You’ll know it was time well-spent when I make you scream my name
tonight.” Hiro said cockily.
 
            “Nii-san…just shut up and kiss me already.” Tadashi chided gently.
Hiro laughed before capturing Tadashi’s lips in a passionate kiss.
 
            Now that Hiro’s left hand was no longer completely immobile in a
sling, Tadashi was showered with gentle caresses all over his back and chest,
much to the younger’s delight. Hiro focused mostly on Tadashi’s back at first,
playfully leaving feather-light touches along his little brother’s spine and
shoulder-blades.
 
            Then Hiro’s hands quickly moved to Tadashi’s chest; Tadashi
whimpered and moaned softly as Hiro played with his pert nipples.
 
            “Does it feel good Dashi?” Hiro whispered teasingly, enjoying just
how flustered his little brother was getting under his touch. He planted a
gentle kiss on Tadashi’s neck, before he focused on his brother’s face; Tadashi
was sporting a beautiful red blush at the moment.
 
            “Mmmhm…” Tadashi nodded slowly, biting his bottom lip to prevent
yet another moan from escaping.
 
            Hiro then kissed Tadashi on the cheek before moving to his ears,
skillfully alternating between licking the outer shell with his tongue and
nibbling the earlobe. Tadashi’s eyes snapped shut at the sensation; it was
becoming almost impossible to not lose himself to the feeling of what Hiro was
tantalizingly doing to him. In consequence, Tadashi didn’t notice how Hiro’s
hands travelled downwards.
 
            “Mmmph…!!” Tadashi moaned loudly when Hiro gave his butt-cheeks a
gentle squeeze. When Tadashi tried hiding his face in the curve of his elbow,
(he was embarrassed at getting caught by surprise) Hiro attacked his exposed
neck, eliciting yet another moan.
 
            “No hiding Dashi…you know how much I love seeing your face and
hearing your voice when you feel good~…” Hiro whispered as he stroked the back
of Tadashi’s thighs.
 
            “…You’re…mean…Nii-san…” Tadashi whimpered.
 
            “And you’re just…so hot…” Hiro said huskily in Tadashi’s ear. “You
turn me on so much…”
 
            “N-nii-san!!” Tadashi exclaimed, embarrassed. Secretly, he enjoyed
Hiro talking dirty to him though.
 
            “It just makes me wish we didn’t have classes so that we can do
this all day long…”
 
            “….Nii-san…” Now Tadashi simply sounded exasperated.
 
            “Just kidding! But I love you so much Dashi,” Hiro said, his tone
of voice completely different from before. He sounded so caring and loving that
it left Tadashi feeling a little confused. “Somuch. I really do.”
 
            There was a brief pause before Hiro finished his thought.
 
            “I wish I could spend more time…just being with you. I just want to
hold you close.” Hiro whispered, hugging Tadashi tightly.
 
            Typical Hiro, always playing with Tadashi’s emotions like a cat
would play with its food before eating it (how he could sound so dirty one
minute and all fluffy and affectionate the next was beyond Tadashi). Still,
Tadashi had no doubt in his mind that his brother truly adored him, so he
simply accepted Hiro’s words for what they were. Honestly he’s like a little
kid sometimes Tadashi thought fondly.
 
            “….I love you too…” Tadashi whispered back, affectionately kissing
Hiro on the cheek. Tadashi wouldn’t have known, but his words and his chaste
kiss just about melted Hiro’s heart. There wasn’t ever going to be anyone Hiro
loved more than Tadashi, for better or for worse.
 
            “You’re so sweet…I think you deserve a treat.”
 
            Hiro reached over to his nightstand and extracted a small brown
vial from his drawer. Tadashi curiously looked at the vial (it was
transparent); he noticed that a bunch of colorful tablets were inside of it.
            
            “Don’t worry they’re not my pain meds,” Hiro explained, twisting
open the vial. “My pain meds aren’t so brightly colored. Anyways, these tablets
contain two active ingredients: one helps improve blood flow and the other
modulates pain perception. Honey Lemon developed the chemicals, as you might
have already guessed, and Wasabi and I collaborated on developing the dosage
form.”
 
            Tadashi blinked for a few seconds before he burst out giggling.
 
            “So what you’re telling me is that you’re offering me drugs. I
don’t even know how you managed to convince Honey Lemon and Wasabi to develop
an aphrodisiac of all things…”
 
            “Way to put it so negatively…” Hiro pouted. “And besides, my
friends have needs too. Maybe not physical needs but…you know, for science.”
 
            “More like I’m just telling the truth…and of course you’d say that.
I don’t know what I expected.”
 
            “You don’t have to take them if you don’t want to. I would never
make you,” Hiro replied sincerely. “They make you feel good though. Real good.
I tested them on myself…you know, just to make sure they’re effective and
safe…a couple of times when it got particularly lonely in the lab or at home…”
 
            Tadashi blushed fiercely at the image Hiro’s words invoked in his
mind; Hiro noticed Tadashi’s reaction and instantly smirked.
 
            “Thinking naughty things are we?” Hiro cooed. See? Fluffy words one
minute, dirty the next.
 
            “N-no…” Tadashi replied, his eyes darting away from Hiro’s.
 
            “You’ve always been a horribleliar,” Hiro said fondly, kissing
Tadashi quickly on the lips, much to the younger’s embarrassment. “But it’s one
of the things that makes you absolutely adorable.”
 
            Hiro popped a random tablet into his own mouth, allowing it to
dissolve underneath his tongue.
 
            “Mmm…strawberry.” Hiro said matter-of-factly.
 
            “Do you have an orange-flavored one?”
 
            “Of course. You sure you want one?” Hiro asked, picking out an
appropriate tablet and holding it in his hand.
 
            “I’ve never been one to turn down free stuff from my precious Nii-
san. I trust you.” Tadashi whispered sweetly before opening his mouth slightly,
inviting Hiro to place the tablet in his mouth; Hiro smirked before placing the
small tablet under Tadashi’s tongue.
 
            To Hiro’s surprise, Tadashi grabbed his hand just as he was about
to retract it; Tadashi’s lips lingered on his older brother’s fingers as he
waited for the tablet to dissolve.
 
            “Mmm…so sweet…” Tadashi smacked his lips twice before he shyly
started licking Hiro’s fingers, his eyes never breaking contact with Hiro’s.
Hiro audibly gulped as he watched Tadashi’s tongue dart between his fingers.
 
            Fuck.
 
            Hiro wasted no time getting the lube from his drawer and lathering
his fingers liberally with it; Hiro pulled Tadashi closed to him once more
before he positioned two of his fingers near Tadashi’s entrance. Tadashi
shivered in anticipation.
 
            “Ready?” Hiro asked gently. Tadashi nodded.
 
            Hiro worked a little slower than usual (this was a relatively new
angle for the two of them after all) but Tadashi didn’t find the slow pace
unpleasant; Tadashi moaned loudly against Hiro’s neck as he felt his brother’s
long fingers tantalizingly brush against his sweet spot for the first time.
 
            “Mmm…Nii-san…that feels good…” Tadashi whispered, moving his hips
in time with Hiro’s fingers; to Tadashi’s annoyance, Hiro purposefully kept his
fingers from penetrating too deeply the minute he started doing so. In
consequence, Tadashi was left feeling distinctively unsatisfied and frustrated.
 
            “Just a little more prepping Dashi…” Hiro whispered, knowing
exactly how much he was teasing Tadashi, the little sneak. “Then you can ride
me allyou want.”
 
            “You really are so mean…”
           
            Hiro smiled smugly before pulling his fingers out altogether.
           
            “Guilty as charged. But in more important news, am I going to have
to lube myself up or are you going to help me?” Hiro asked, shaking the bottle
of lube in Tadashi’s face.
           
            “I swear, if I didn’t love you as much as I did…” Tadashi grumbled
before gently taking the bottle from Hiro and pouring some lube onto his hands.
           
            “I’m very lucky that you do. I know.” Hiro said sweetly, kissing
Tadashi on the forehead as Tadashi rubbed his hands together to warm up the
lube.
           
            “You have an awfulway of showing it sometimes Nii-san…” Tadashi
said half-exasperatedly and half-affectionately. Hiro simply reached over and
gave Tadashi’s neck a light bite in response.
             
            Tadashi worked quickly and efficiently lubing Hiro up (as he was
quite impatient after all of Hiro’s teasing earlier) before the two brothers
repositioned themselves on the bed. Once Hiro settled down comfortably on his
back with his head propped up with a pillow, Tadashi climbed on top of him.
Tadashi took in a deep breath before slowly lowering himself onto Hiro’s
erection, whimpering softly as he did so; in comparison, Hiro groaned deeply.
 
            “God…” The two simultaneously whispered breathlessly when Tadashi
took almost all of Hiro in. They blinked at one another before briefly bursting
out into giggles.
 
            “Jinx…you owe me a soda.” Tadashi couldn’t help but whisper softly.
They were in the middle of having sex, yet here they were, acting like innocent
children; it was paradoxical, but in a strangely charming way.
 
            “Sure thing kiddo. I’ll get you some from the fridge later.” Hiro
whispered back. He placed his hands gently on Tadashi’s hips; in response,
Tadashi gently braced his own hands against Hiro’s lean chest.
 
            “You ready?” Hiro whispered tenderly.
 
            “Yeah…”
 
            Their rhythm was slow and sweet at first. For the most part, Hiro
let Tadashi set the pace and how much he was penetrated; meanwhile, he simply
took the time to enjoy the view of his beautiful younger brother rising and
lowering himself above him. Tadashi found the position a little embarrassing at
first, but after he realized just how aroused Hiro looked gazing up at him, he
steadily grew more confident.
 
            Eventually, Tadashi grew dissatisfied with the slow pace and boldly
sped up; in response, Hiro’s grip on Tadashi’s hips tightened.
 
            “Ah…ah…Nii-san…” Tadashi moaned.
 
            “Ngh…Tadashi…” Hiro groaned in response. He started moving his own
hips to meet Tadashi half-way, resulting in Tadashi moaning even louder.
 
            “Y-yes, right there…right there!” Tadashi yelled wantonly as he
felt Hiro finally hit his neglected sweet spot.
 
            “Fuck Dashi….if you keep yelling like that I’m going to lose it…”
Hiro whispered, closing his eyes to help him concentrate. He could feel his
blood burn hotter and hotter, and the sinful appearance of Tadashi losing
himself to pleasure wasn’t doing anything to help that.
 
            Tadashi didn’t know it, but the aphrodisiac Hiro had given him
earlier decided to really kick in right then and there; the pleasure shooting
through his body suddenly doubled. In consequence, it took only a couple more
thrusts before Tadashi was temporarily overwhelmed; Tadashi came with a
breathless moan.
 
            When his vision cleared and his head stopped spinning, Tadashi
caught sight of the surprise on Hiro’s face. Tadashi’s eyes then travelled down
to his brother’s chest, which was now covered in ribbons of white. When Tadashi
realized what had just happened, he was instantly mortified.  
 
            “S-sorry Nii-san…” Tadashi apologized. He sounded absolutely
devastated. “I-I just…”
 
            “It’s fine,” Hiro said instantly. He gave Tadashi an affectionate
pat on his hip, smiling all the while. “I’m glad you got to enjoy yourself.”
 
            “But you’re not…”
 
            “It’s fine. You did most of the work anyway, so of course I held
out longer than you this time. I just got caught by surprise that’s all.” Hiro
said matter-of-factly as he gently eased himself out of Tadashi. Tadashi
couldn’t help but whine at the loss.  
 
            Hiro quickly wiped himself down with his discarded shirt before
propping himself up against the headboard again and pulling Tadashi to him. He
stroked Tadashi’s hair soothingly.
 
            “Nii-san…” Tadashi whispered, sounding quite like a kicked puppy.
 
            “Shh…shh… It’s ok.” Hiro replied, gently shushing his younger
brother. He then kissed Tadashi softly on the cheek.
 
            “How could it be ok? You haven’t come yet.” Tadashi said, glancing
down at Hiro’s still quite hard erection.
 
            “…Well the night is still far from over. Do you think you’re up for
round two?”
 
            Tadashi thought about it for a few seconds before nodding shyly.
Now that he thought about it, he wasn’t quite satisfied. Was it because of the
drug?
 
            “You can still feel the chemical working in your veins can’t you?”
Hiro whispered huskily in Tadashi’s ear, as if he was reading Tadashi’s
thoughts. Tadashi’s body shuddered traitorously in response.
 
            “You planned this didn’t you…” Tadashi accused quietly after a
brief moment of thought. Hiro chuckled.
 
            “Well, you give me too much credit. I had a theory…a vague idea
that it might work. I had no solid proof though…until now.”
 
            “U-unbelievable…”
 
            “I’ll make it worth it Dashi…believe me.”
 
            Hiro guided Tadashi to lie down on his left side; Hiro then settled
behind Tadashi, taking a brief moment to kiss all along the younger male’s nape
and ears and massage along the curve of his hip. Tadashi found himself getting
hard again in no time, something Hiro was keen on pointing out, much to his
embarrassment.
 
            “Ah, what it is to be young~.” Hiro cooed as gently bit Tadashi’s
neck.
 
            “Be nice to me Nii-san…”  Tadashi begged softly, arching his back
against Hiro’s chest. His body was getting hotter and hotter, almost to the
point of slight discomfort; the effects of the aphrodisiac must have been
hitting its peak. Hiro was feeling the same heat as Tadashi was, but because he
had more experience with the drug, he was more tolerant of it.
 
            “When you ask so cutely like that, how could I refuse?
 
            Hiro kissed Tadashi’s neck one last time before gently lifting up
Tadashi’s leg and once again positioning himself at Tadashi’s entrance.
 
            “I’m putting it in ok?” Hiro whispered.
 
            “Mmm…please hurry Nii-san,” Tadashi whispered back. “I’m getting so
hot…”
 
            “I know kiddo, I know…I’ll take care of you…”
 
            With one smooth motion, Hiro entered Tadashi again, making Tadashi
cry out in pleasure; Hiro allowed Tadashi to adjust to him for a couple of
seconds before he started rolling his hips.
 
            “Nngh...Nii-san…” Tadashi gasped breathlessly.
 
            “Dashi…” Hiro groaned low in Tadashi’s ear.
 
            “Please…go…faster…” Tadashi begged.
 
            “Ok…lean on your arms so I can let go of your leg…”
 
            Tadashi did as he was told; Hiro anchored his now free hand against
the bed and started a faster rhythm. To further drive his younger brother over
the edge, Hiro started kissing all over the back of Tadashi’s neck and his
ears. Tadashi’s fingers clenched the bed sheets so tightly that his knuckles
turned white; his back arched beautifully against Hiro’s body.
 
            “Ngh…Ah! Nii-san!”
 
            The sounds coming out of Tadashi’s mouth at this point were
becoming simply illegal; in consequence, Hiro started thrusting even faster,
pounding into Tadashi, eager to satiate the burning desire that was almost
overwhelming the both of them.
 
            “Dashi..!” Hiro groaned desperately. He was so close, but he wanted
to finish Tadashi off first.
 
            “N-Nii-san…I c-can’t…” Tadashi gasped. Hiro could feel Tadashi’s
abdomen tighten under his arm.
 
            With the last of his strength, Hiro grabbed for Tadashi’s right
hand with his own, interlocked their fingers, and brought Tadashi’s hands up to
his lips. It was such an intimate gesture that Tadashi once again found himself
momentarily overwhelmed; with a strangled cry, Tadashi came for the second time
that night. With a low groan, Hiro came shortly after.
 
            The two spent the next couple of minutes desperately trying to
catch their breath. Hiro, unsurprisingly, recovered first, and promptly pulled
out of Tadashi; Hiro then gently hugged Tadashi closer to him so that he could
breathe in his scent and cuddle him affectionately. When Tadashi recovered, he
slowly turned himself around so that he could kiss Hiro softly on the lips. The
kiss was passionate, but not in a sexual way; rather, it was passionate in a
deep emotional sort of way. When they pulled apart, they gazed into one
another’s eyes for a few seconds before bringing their foreheads together.
 
            “Hey…” Hiro whispered softly, breaking the silence.
 
            “Yes?” Tadashi replied.
 
            “Are you ok kiddo?”
 
            “Mmm…I’m fine Nii-san…”
 
            “Good…”
 
            Hiro gently kissed Tadashi’s cheek one last time before sitting up.
 
            “Hm…we’re going to have to change and wash the sheets again.”
 
            Tadashi couldn’t help but laugh tiredly.
 
            “What’s this ‘we’ you speak of Nii-san…we all know who’s going to
change and wash the sheets.”
 
            “…Dashi…”
 
            Tadashi felt Hiro nudge his body with his leg (a silent request for
Tadashi to lift himself up); he slowly sat up, a little confused.
 
            “Can you just step off the top sheet?” Hiro asked softly. It
appeared that Hiro was dutifully removing the soiled bed sheet; in consequence,
Tadashi stepped closer to the headboard, getting out of Hiro’s way.
 
            Tadashi was surprised to see another top sheet underneath the one
Hiro had just started rolling up; Hiro pulled out the last corners of the
dirtied sheet from underneath the mattress before he tossed it haphazardly to
the floor.
 
            “Told you I had gotten it all figured out.” Hiro said, shooting a
small wink at Tadashi, who blushed slightly in response.
 
            “That’s…surprisingly responsible of you Nii-san…” Tadashi replied,
though he didn’t bother pointing out that he was probably still going to be
responsible for putting the sheet in the wash, not Hiro.
 
            “I try. Sometimes.” Hiro said in an almost bashful way, and it just
about melted Tadashi’s heart (not that he’d ever said it out-loud though).
 
            Hiro then pulled out some clean boxers and T-shirts from his bottom
drawer; he then pulled Tadashi into his lap before he pulled a shirt over
Tadashi’s thin body.
 
            “I thought I was supposed to dress you Nii-san…” Tadashi whined
half-heartedly as Hiro slowly put on a shirt himself.
 
            “You have my full permission to dress me under every other
circumstance besides having great but exhausting sex,” Hiro replied. “And
seeing how you’ve been through quite a bit tonight, just let me take care of
you for once.”
 
            “…Ok…” Tadashi said softly. Hiro didn’t see it (because he was busy
with helping Tadashi put on a clean pair of boxers), but Tadashi smiled a small
but very happy smile. He can be so sweet when he wants to beTadashi thought
fondly.
 
            After Hiro put on boxers, the two settled back down on the bed;
Hiro reached over to his nightstand to grab the remote control that turned off
their bedroom light and clicked the appropriate button. Soon, darkness
descended upon the two brothers.
 
            “Goodnight Dashi.” Hiro whispered tenderly.
 
            Hiro’s words were met with silence. Hiro waited until his eyes
adjusted to the darkness before he glanced down at Tadashi; he wasn’t surprised
to see that Tadashi had passed out, his chest rising slightly with each steady
breath he took.
 
            “Wow, falling asleep before wishing me a goodnight? Talk about
rude.” Hiro couldn’t help but huff, bratty behavior back in full swing. But his
annoyance didn’t last long; it only took a few seconds of gazing at Tadashi’s
peaceful sleeping face for Hiro to smile affectionately once more.
 
            “It was probably a side-effect of the drug. Maybe I should consider
adding a small amount of caffeine to it or something.”
 
            Hiro chuckled softly to himself before he closed his eyes. It was
definitely something fun to look forward to when he got to return to his lab
with full functionality of his arm and leg.

Chapter End Notes
     *brushes off hands* FINALLY. I’m glad that’s over lol. I’ve come to
     realize that I really don’t enjoy writing smut all that much…I find
     it very difficult *sweatdrops* And the payoff is kind of unrewarding
     (ahahahaaa pun fully intended lol). And wow oops I forgot to mention
     turning off the lights in the first part of this two-shot ackkkk. /
     hurrdurr orz
     I laugh at myself whenever I think about how much “scientific”
     research I actually did to write this two-shot...orz I’m going to
     ramble a lot so…yeah be warned.
     For example, why did I even bother writing Hiro injuring himself?
     Well, one of the best reasons for using the “cowgirl position” and
     the “spoons position” is if the person who is doing the penetrating
     is injured, so I just felt obligated to use that small trivia fact in
     my story even though I really really didn’t need to lawl (it cost me
     some additional 4000+ words in exposition ugh why do I do this to
     myself?). Like seriously I could’ve just written Hiro allowing
     Tadashi to be on top because why not, it’s a nice position but noooo
     I had to write it a completely different way orz. But I guess it made
     for some cute Age Swap! moments so, whatever no true regrets.
     Also I always find it interesting how aphrodisiacs are usually
     mentioned in fics/doujins. I think a lot of aphrodisiacs in doujins
     are usually liquids (probably due to liquids being aesthetically
     pleasing to draw), and the pharmacy student in me is like, “Do you
     realize just how long it’d take for that drug to actually start
     working in the body? Way too long (like we’re talking hours here
     lol).” As far as fics go, I guess I see a mixture of aphrodisiacs
     being powder/liquid. I guess powder should exhibit rapid absorption
     as long as you “snort it”, so that’s pharmacologically feasible XDDD
     (though dangggg I hope the character’s nares are spared from the drug
     lolool). But sublingual absorption of drugs should be fairly quick
     (think your nitrate medications aka the stuff you pop into your mouth
     when you happen to feel a heart attack coming on), so it should be
     feasible for an aphrodisiac to be designed in such a way if you want
     to pop a tablet right before you start getting down and dirty xD In
     comparison, an oral-disintegrating tablet, which usually have an
     onset of action of about 30 minutes, would be good to pop in around
     the time of foreplay lol.
     So I guess I tried justifying writing smut to myself by telling
     myself that I’m totally applying my studies of pharmacokinetics/
     pharmacology mmmm yep yep see the lies I tell myself? Hahaha I’m just
     like Tadashi in this story I suppose lol orz
     TL;DR: I’M A TURBO NERD LOSER I’M SO SORRY. I JUST HOPE YOU ENJOYED
     MY SMUT SOMEWHAT. I’M STILL TRYING VERY HARD TO LEARN HOW TO WRITE IT
     PROPERLY. TvT)/
     As always, you can find me at Rl4r.tumblr.com! <3 I’d love to hear
     suggestions!!
     Oh, P.S. The whole intro of the second chapter is dedicated to
     someone. You know who you are. ;)))) /slamdunked into trashcan
End Notes
     Author’s Note: The only regret I have for this is that it’s so
     freaking long oh my god. Why…And wow the actual smut is SADLY short.
     I'm so sorry. /sighs deeply
     But well, now that I’ve done a lot of necessary exposition, part two
     can be solely dedicated to smut! Yayyyyyyyyyyyyyyy. /shot
     Thank you so much for reading! Hope to see you all for part two! <3
     You can always find in me in the trashcan at Rl4r.tumblr.com!!! I’d
     love to hear suggestions on any of my fics/suggestions for future
     fics. Thanks a lot! <3
