****** A Heated World ******
by A_Fallen_Fate
Summary
     To survive extinction, races changed to create what we know today as
     alphas, betas, and omegas. These adaptations altered the world but
     some things would never change.
     Pirates still sailed the seas, Marines sought to capture them and
     maintain justice, and Monkey D. Luffy was going to become King of the
     Pirates. The fact that he was an omega and already mated to Ace
     didn't change anything, because nothing was going to stop him from
     achieving his dream. Nothing.
Notes
     So I've had this story brewing in my documents folder for longer than
     I can even remember and I have finally decided to post it. I only
     have a few chapters written but I have a general outline of events
     and plot points.
     The main reason I'm posting this story now is because I'm curious to
     see how it will grow and change with actual readers. As such, feel
     free to hit me up with ideas/things you'd like to see in the story.
     Depending on the request, I may add it.
     That being said, I do hope that you all enjoy the story and PLEASE
     for the love of all the is One Piece, leave a comment! I have no idea
     if this story is even good anymore and would love the encouragement.
     Now, without further adieu, here is A Heated World!
See the end of the work for more notes
***** New World *****
 
For as beautiful and dangerous as their world was, covered by vast seas and
unique islands, there was little known about what it was like before the void
century. All that people could say for certain was that somethinghad happened
that caused the world’s populations to plummet drastically until nearly every
race faced extinction.
With such dire and hopeless times, it seemed as though their world, or at least
their time in it, was about to end. However, after a few centuries of living on
the brink of complete annihilation, their bodies started to adapt, creating
three secondary sex characteristics: alpha, beta, and omega.
Each one altered the bodies of humans, fishmen, and all other races alike in
such a way that would ensure that they would never be faced with a similar
disaster again.
As people grew accustomed to their altered bodies, it became increasingly clear
that these adaptations were meant to help increase population numbers quickly
and also ensure their survival as they did.
For alphas, their bodies altered in a way that made them able to withstand
nearly anything that came at them. Tests concluded that this resistance came as
a higher pain tolerance, stronger bones, and improved healing capabilities.
Along with this was a fierce, nearlyunstoppablestrength that could either
protect or destroy, depending on who it was directed towards.
Together, both of these qualities ensured that extinction would not come so
easily next time.
Understandably, these qualities were highly admired and envied. So much so that
eventually, being an alpha was considered to be the best characteristic and
thus, the remaining two received a less desirable reputation.
Nevertheless, even though betas were regarded as the most ‘normal’ out of the
three, being that they didn’t have any inherent adaptations like alphas and
omegas, they still had their strengths.
For instance, they were known to be the most level-headed in times of crisis
and more often than not, provided guidance for the remaining two. Not only
that, but many betas went on to become leaders, teachers, and some of the most
influential people in improving society.
Last but most certainly not least were the omegas, the ones most responsible
for saving the world’s populations from being completely wiped out.
An omega’s body, strong even though the majority of omega’s were smaller in
stature and size overall, adapted to be able to withstand multiple pregnancies.
However, along with this came a physical (and sometimes mental) needto mate and
breed that was so strong, that eventually the term ‘heat’ was created to
describe what an omega went through every month.
Alpha’s went through something slightly similar every two months where their
testosterone levels rose, increasing libido and strength as they sought out a
mate, a so called ‘rut’.
Together with an alpha’s strong libido and an an omega’s fertile body, the two
were the most desired mating pairs as their bodies were the most suited for it.
Regarding an omega’s heat, they varied in length and severity by a multitude of
factors, all but not limited to: age, mated status, and proximity to potential
mates.
Another known fact was that, for the most part, a person wouldn’t actually
transition into an omega until they were seventeen, as that was usually when
they were physically ready to bare children.
That being said, it was possible that they could transition earlier but if that
were the case, they would not be physically capable to have children until they
reached the age of seventeen.
This helped ensure that omega’s wouldn’t accidentally have children before they
were old enough to decide and better take care of them. Of course, mated pairs
could still occur at a young age but was usually frowned upon.
Somewhere along the line, people started seeing omegas as lesser beings whose
only use in life was for sex and pumping out babies. This horrible stigma
continued on until omega’s could hardly strive to do anything else but simply
look for a mate (usually an alpha) who could take care of them.
Of course, not all people thought of omega’s this way but life was inherently
harder for them because of it.
Although, that wasn’t to say that alphas or betas didn’t face challenges with
stereotypes, it was just that omega’s dealt with it so much worse and on a much
larger scale.
Either way, each characteristic had it’s difficulties but it was simply a fact
of life that come puberty, everyone would transition into one of the three, as
two boys by the names of Portgas D. Ace and Monkey D. Luffy, would soon learn.
 
***** A Frustrating Change *****
Chapter Summary
     Ace's day was turning out to be filled with nothing but confusing
     feelings and embarrassing realizations. Of course, what did he expect
     as a new alpha going through his first rut?
Chapter Notes
     Alright, here is (technically) the first chapter! I hope you all
     enjoy and please leave a comment!
 
A dense field of debris made up of shattered trees surrounded him to such a
point that it was all he could see past the dark green vines and blue sky above
him.
He had been out there in the middle of the forest for hours, trying his best to
squash this feeling of frustration that burned deep inside of him: it’s red hot
core refusing to extinguish.
For the life of him, Ace couldn’t understand why he was feeling this way.
There was no rhyme or reason to it, he simply felt frustrated to a point that
it had begun to anger him. Not only that, but his body felt . . . offsomehow
and it continued to feel this way regardless of all that Ace had done to try
and fix it.
In the end, that was the whole reason he was out there in the first place.
After each of his attempts continued to be unsuccessful, he had gotten fed up
enough that he had marched out into the vast forest, leaving Luffy behind at
Dadan’s, to see if taking his anger out on the trees would help.
However, watching as the last tree he hit came tumbling down onto the jungle
floor with a loud BANG, Ace realized that even thathadn’t helped.
“SHIT!” he cursed, slamming his bruised fist into the dense bark of the tree
next to him, his irritation getting the better of him. The bark splintered and
cracked from the force but it was far from the worse thing that he had caused
today, the shattered remains of former trees could attest to that.
Pulling his hand away, Ace cringed at the sight of his bleeding knuckles but
was surprised that he felt no pain coming from them. Usually he would at least
feel tingles shoot out from the stiff joints, but today, nothing and for as
strange as it was, he was simply too tired to care.
Falling back onto the grassy forest floor, Ace let out a frustrated sigh as he
stretched his tired limbs out beside him.
It seemed that whatever it was inside of him didn’t crave destruction and at
this point, Ace was having a hard time figuring out what else it could possibly
be.
Neither eating, swimming, or even trying to run it off had helped and with
fighting (rampaging, really) proving unhelpful too, he was at a loss.
Dammit. Ace thought to himself, an angry line forming between his brow. Maybe
if I just sleep this feeling will go away on it’s own.
Decision made, Ace allowed his eyes to close as he immersed himself in his
surroundings from the cool touch of the mountain breeze to the hard earth
beneath him.
The serenity of Mount Colubo always provided a sense of comfort for him. It was
the place he could hide away from judging eyes and simply be himself, where he
was simply free.
Releasing a deep breathe, Ace relaxed his body and cleared his mind. Just as he
could begin to feel himself falling asleep, his keen ears caught the rather
obvioussounds of someone making their way through the forest and towards him.
Cracking one eye open, Ace turned his head to the left and saw a familiar
twelve year old maneuvering his way through the debris to get to Ace. Seeing
that Luffy wasn’t all that much of a threat (not to him anyway), Ace turned his
head away and closed his eye again.
However, he couldn’t help but continue to listen as Luffy continued coming
closer to him before he eventually stopped right next to Ace. Not in the mood
to deal with Luffy’s badgering (as he no doubt would do), Ace was content to
simply let Luffy think he was sleeping.
Of course, it was hard, damn near impossible, to ignore Luffy.
“Nee, Ace?” Luffy began, poking a small finger at Ace’s freckled cheek.
“Aceeeee.”
“What?” he snapped back, still determined to keep his eyes closed.
“Are you sleeping?” Luffy asked, poking this time at Ace’s nose.
Sighing, Ace contemplated throttling Luffy for his shitty timing and insistent
need to bother him when he wanted to be left alone but decided against it.
After all, Luffy didn’t knowhe was currently fighting with some part of
himself, so it wouldn’t be fair of Ace to take his frustration out on him.
“Not anymore,” he began as he sat up, staring almost eye level with Luffy who
was sitting on his knees in front of him. “What did you want?”
“Oh good! I wanted to tell you something,” Luffy explained with a grin that was
a touch mischievous but mostly one of excitement.  
Quirking an eyebrow at the sight, Ace rested his arms on his legs to try and
get comfortable again. “Okay, what is it?”
“No, you have to guess!” Luffy insisted with a pout, folding his thin arms
across his equally as thin chest. Seriously, the kid was small, even for
someone his age.
Bringing a hand up to rub at the back of his head, Ace willed a migraine to
stop forming. Luffy hadn’t even been there for five minutes and already he was
being a pain. It may sound cruel but he loved Luffy, really he did, it was just
that sometimes, he demanded the stupidest of shit that really grated on Ace’s
nerves.
“Luffy, I’m not going to sit here and guess, okay? Now just tell me.”
“No! If Ace isn’t going to guess then I’m not telling him!” With a huff, Luffy
turned away from Ace and his reddening face.
“You’re so stupid!” Ace couldn’t help but snarl back, his frustration bubbling
up inside of him to a point where it almost felt like it was trying to crawl
out of his throat to attackLuffy. “If you’re not gonna tell me then just go!”
Hearing the insult, Luffy’s eyes widened (if that were at all possible) before
they slitted in his anger. “I’m not stupid!” Luffy snapped back, standing up
from his position on the ground.
“Yeah, says the idiot who doesn’t even know how to swim!” Ace countered,
standing as well, his much taller and broader form towering over Luffy.
Three years made quite the difference it seemed.
At the comment about his inability to swim, Luffy’s bottom lip began to quiver
and tears began to build up in his large brown eyes.
“You know that’s not my fault! Nobody who eats a devil fruit can swim!” Luffy
cried out, pulling his bottom lip in between his teeth to try and keep himself
from crying.
It was a sight Ace had long since gotten used to seeing as he had always given
Luffy shit for crying in front of him. He had tried to lay off of it since Sabo
died, but it looked like Luffy was still trying to stop being a crybaby.
“Some excuse, you couldn’t swim with floaties on even before you ate the Gomu
Gomu no mi!”
“Y-yeah well, you smell weird!” Luffy yelled back, a few tears leaving salty
streaks down his face as his nose started to drip with snot.
Cringing at the sight, Ace almost felt bad for picking on something that Luffy
had always been sensitive about. However, hearing the comment about his
apparently weirdsmell, Ace didn’t feel quite as bad anymore.
“I don’t smell weird!” Ace growled, his face flushing in embarrassment. Even if
he had been getting quite the workout today, he had bathed the night before and
honestly, Luffy should be used to how he smelled by now.
Besides, Luffy usually smelled the same!
“Yeah you do!” Luffy insisted, rubbing angrily at his tears to try and get them
to stop but failing rather miserably.
“Oh yeah, then what do I smell like!?” Ace watched quietly as Luffy’s face
scrunched as he tried to think, his round face gradually turning into an ugly
shade of red as his mind worked in overdrive, something it so rarely did.
“I . . . I don’t know! Just weird!”
“Hah, goes to show how stupid you are if you can’t even figure out what I smell
like!” Ace jeered, letting his emotions get the better of him. He couldn’t help
it, his mood had been bad enough today and Luffy pestering and insulting him
didn’t help matters.
“You jerk!” Luffy screamed, his eyes an angry red from his tears. “I’m going to
tell Makino not to give you any of the yummy food she’s making tonight!”
Hearing the familiar name of basically their second surrogate mom (second after
Dadan), Ace’s eyes widened in surprise. “Wait, Makino? Makino is here?” he
asked, tilting his head in confusion.
He usually heard about Makino coming up to visit them at least a week in
advance, that way they could make sure that they would be there at Dadan’s when
she arrived.
He wondered why she was coming up all of a sudden? Surely nothing bad must have
happened, right?
“Yeah—Wait, I was going to make you guess that!” Luffy whined, stomping his
sandaled foot, kicking up flecks of dirt as he did.
“Haha! You idiot!” Ace laughed, holding onto his stomach because of the sheer
force of his laughter. He knew it was childish of him, but he simply couldn’t
help it: Luffy was too cute when he was angry.
In response, Luffy grounded his teeth so hard that Ace could almost hear the
molars scraping against each other. “I’M NOT AN IDIOT!” Luffy finally snarled,
a roar ripping out of his throat as he jumped at Ace, his fist swinging.
It wasn’t at all difficult to dodge Luffy’spoorly aimed fist but even so, Ace
wasn’t gonna just let it slide. As such, he returned it with a well-placed
punch of his own, striking rubber skin instead of air like Luffy’s had.
Recoiling from the punch, Luffy hissed in pain as he staggered backward,
holding onto his already reddening cheek before jumping at Ace in retaliation.
Together they fell back hard onto the solid ground, tussling around as they
continued to try and injure the other, throwing punches and kicks alike.
Being larger and simply that much stronger than Luffy, it wasn’t long before
Ace had gained the upper hand. However, in a last ditch effort to win, Luffy
bit hard, digging his admittedly sharp teeth into the muscled flesh of Ace’s
bicep, nearly piercing the skin there.
Hissing more in discomfort rather than pain, Ace tried to retract his arm from
Luffy’s mouth but the twelve year old held strong.
“ARGH! Dammit Luffy, let go!” Ace demanded, pulling at Luffy’s cheeks to try
and get the small boy to retract his teeth from Ace’s arm.
All he got in return was Luffy grumbling a faint “no”, his voice muffled by his
current position. Hearing this, Ace couldn’t help but growl at the refusal
before trying again in vain to pull away from Luffy’s strong jaws.
In response, Luffy only bit harder, lightly piercing the skin enough so that it
started to bleed.
Yelping at the sudden sting, Ace glared daggers at the top of Luffy’s head.
Fine, if Luffy wanted to be difficult then two could play at that game.
Leaning forward with this goal in mind, Ace’s teeth latched onto Luffy’s
shoulder before biting down hard enough that if it wasn’t for the fact that
Luffy was currently in a t-shirt, he was positive that his teeth would have
pierced through both skin and muscle.
“OWW!” Luffy screamed, releasing Ace’s arm as he fell back onto the ground,
pulling Ace with him.
Retracting his teeth, Ace pulled away and pushed himself up slightly so that he
wouldn’t be squishing the younger (not to mention, smaller) male. “See, hurts
doesn’t it—”
Ace’s voice choked off with with a stutter, something akin to a whine building
up in his throat as he realized what position Luffy and himself were in.
Normally, having Luffy pinned underneath his larger body wouldn’t have done
anything to Ace, but today it did.
Knowing that he had Luffy trapped and unable to escape sparked something inside
of him that warmed his core and sent chills up and down his spine.
It excitedhim.
It was with this startling realization that Acefinally figured out what the
thing inside of him had wanted all this time: Luffy.
Understanding this, Ace couldn’t help but feel horrified with himself when he
felt his body warm and his cock rise against the dark fabric of his cargo
shorts, completely erect at the thought of taking Luffy as his own: claiming
him in every way imaginable in body, mind, and soul.
He could imagine marking his smooth, rubbery body so that everyone would know
that Luffy was his and it made him shudder from head to toe. Ace wanted to fuck
him so hard, and so deepthat all Luffy would feel after would be the phantom
presence of Ace’s cock still lingering within.
God, Ace wanted Luffy, in so many ways and, really, who was going to stop him
if he tried?
As all these obscene thoughts filled his mind, each one worse than the last,
Ace couldn’t help but blush a fierce crimson before his face twisted into an
expression of shocked horror, not able to stop himself from thinking about
Luffy this way.
Noticing his brother's sudden discomfort, Luffy paused in rubbing his wounded
shoulder to stare up in worry at Ace.
“Ace, are you okay? You look sick.” Luffy frowned, a worried wrinkle forming
between his brow and Ace felt like vomiting.
He was, wasn’t he? Sick, that is. After all, Ace had to be the sickest person
in the entire world if he was wanting to fuck his little brother—A twelveyear
old.
Jerking away from Luffy as that sunk in, actually feeling physically ill now,
Ace scrambled backward until he was a relatively safe distance away from Luffy
and his worryingly enticing body.
Although, the distance only seemed to make the beast inside him hungrier, which
meant that Luffy really wasn’t safe until he was far away from Ace.
“I-I’m fine Luffy. Just go on to Dadan’s without me. I’ll be there later,” Ace
stumbled out, his voice strained.
“But Ace—”
“Just go, Luffy!” Ace roared, glancing up to see Luffy standing a few feet from
him, his hands twisted in his dark blue t-shirt and his plump lips caught
between his teeth.
Seeing the familiar sight, Ace knew that this meant that Luffy was really
worried about him, but it just made Ace crave him that much more. If Luffy
didn’t leave right now, there was no telling what Ace would do to him.
Or rather, how longAce would carrying out all the ideas that were still
swimming around in his head, the beast inside of a him a shark, eyeing the prey
in front of him.
Thankfully, Luffy decided to actually listen to Ace for once in his life and
turned to leave, sparing one last, worried glance back towards Ace’s hunched
form before quickly running off to Dadan’s.
As Ace watched Luffy finally leave, he felt the beast inside him grow. It made
his flesh burn hot and his heart ram itself against his chest.
Luffy wanted Ace to chasehim, didn’t he.
No! Ace thought, slamming his head into a tree to try and stop himself from
going after Luffy, whom he had just told to leave so that he could prevent
anything from happening.
That being said, Ace reallywanted to fuck him.
With a frustrated groan, Ace glanced down at the large tent in his shorts and
glared at it. The damn thing hadn’t receded at all even though Luffy was now
long gone, safe from Ace and the monster inside of him.
Fine, if it really needed to be sated that badly then surely a solo handjob
would do just fine.
Leaning back against the thick wood of the tree behind him, Ace unbuttoned his
shorts and pulled down his zipper, allowing his erection to be freed and stand
against the warm air of summer.
Eyeing the flushed red tip, Ace took it in his hand, calmed by its familiar
weight and feel before gently running his closed first up and down the shaft of
his cock.
Hissing as his body tingled in pleasure, Ace pinched at the tip, his thumb
rubbing gently against the slit and catching the precum into his hand before
spreading it along his length, allowing for a faster pace.
Losing himself in his intense arousal, it wasn’t long before he was panting for
breath as his body grew ever hotter. However, for as aroused as he was, a part
of him wished for something better than just the familiar grip of his fist.
Like, maybe if he hadn’t let his conscious get to him, he could have been seven
inches deep into Luffy right now, making him beg for all that Ace could give
him.
He could picture it so vividly and Ace’s hips started to jerk up into his hand
as he quickened his pace, a  pressure beginning to build at the base of his
shaft.
Just as he was beginning to cum, fueled by erotic thoughts about his adorable
little brother, Ace felt something literally popfrom his dick.
Glancing down in horror, Ace stared with wide eyes at the ring like thing that
surrounded the base of his shaft before ripping his hand away from his
shockingly, still fully erect cock.
Too stunned and horrified by the strange sight, Ace was unable to process the
sounds of someone coming towards him, so when Makino finally made her way
through the scattered debris of trees from Ace’s earlier rampage, all he could
do was stare up at her, frozen.
"Ace! There you are, Luffy was worried," Makino scolded, relief spreading
across her face before her eyes finally glanced down. "Oh!"
Ace flushed a dark red as he tried to quickly shove his stupid erection back
into his shorts in a lame attempt at retaining what was left of his dignity.
Quickly realizing the situation, Makino covered both her eyes with her hand,
backing away slowly from the fifteen year old. “Ace, sweetie, it’s okay! I’m
just gonna head back to Dadan’s, but come see me once you feel better so I can
explain what’s going on.”
With that, Makino headed back in the direction of the house, leaving a fully
mortified Ace behind her.
Ace just continued to stare after her, his blush inflaming his freckled face
before he shakily stood and ran—as best as he could with an erection—towards
the nearest river.
There was no way in hell he was going to risk someone else coming upon him in
this stupid state and if that meant jumping into a freezing mountain river then
so be it.
Trudging into the rather slow moving water, Ace hissed at the coldness of it
before giving a sigh of relief as his stupid erection finallywent flaccid.
Ace stayed there, standing in the river for a moment, enjoying the coolness
against his flushed skin before he finally waddled out, his shorts and shoes
drenched. The bottom of the purple t-shirt he wore was in the same, miserable
condition.
Grumbling at his own stupidity for not having the hindsight to take off his
damn shoes before walking into a river, Ace trudged towards the direction of
Dadan’s house. Hopefully, he would find the answers to whatever the hell was
going on with him there.
After about ten minutes of walking, Ace finally managed to reach the house, his
clothes still drenched even after the short walk in the hot air of the forest.
“Ace! You’re back! Are you feeling any better?” Luffy asked, his face cheerful
as he bounded up next to his brother, ignoring the fact that Ace was currently
drenched.
Ace could feel the monster inside of him react to Luffy’s proximity and almost
wanted to cry because, was this how it was always going to be from now on?
Fighting off the monstrous urge to bend Luffy over and fuck him into oblivion?
Almost as if she sensed Ace’s discomfort, Makino appeared from inside the
house.
“Luffy, Ace still isn’t feeling all that well. Why don’t you go run and play
until he does, okay?” Makino suggested, smiling gently at both of them.
“Ah okay. I hope you feel better, Ace!” Luffy yelled before running off back
towards the forest to do god knows what.
Now with Luffy gone, Ace breathed a sigh of relief as the beast inside calmed
itself before he turned to face Makino, a blush of shame already dusting his
freckled cheeks.
“Ace, why don’t you go get changed out of those wet clothes, then if you want
to talk with me we can, alright?” Makino said,  stepping out of his way.
Ace nodded before he headed into the house and quickly made his way to his and
Luffy’s shared bedroom.
Now that he thought about it, sharing a room with Luffy was going to be a
problem now wasn’t it?
Closing the door of his room, Ace slowly pulled off his wet clothes and dried
himself with a towel before he changed into a dry pair of black basketball
shorts, an orange tank top, and some sandals since his shoes were now drenched.
Picking up his nearly ruined shoes, Ace took them outside with him so that they
could dry in the sun while he and Makino talked.
Placing the shoes by the door of the house, Ace walked over to Makino who was
smiling gently at him over by his and Luffy’s countries.
“Now that you’re changed, how about we go somewhere to talk?” Makino offered,
her face patient as she waited for Ace to answer.
Honestly Ace was actually grateful that it had been Makino who had stumbled
upon him rather than someone else. At least she was attempting to be
understanding and not trying to make this entire situation even more awkward
than it already was.
If say Dadan or (god, forbid), Garp had found him, Ace knew that this
conversation would be a lotworse.
Although, it didn’t change the fact that he’d be talking about thatwith Makino.
“Y-yeah that’s fine. Where are we going?” Ace replied, his body rigid with
tension.
“Hmm, I thought we’d just go over to one of those fields near here. That way
Luffy and the others won’t interrupt us,” Makino said with a kind smile.
Giving a terse nod, Ace followed after Makino as she headed towards one of the
many fields that surrounded the island. The one that they went to was the
closest to Dadan’s house but still far enough away that no one should hear
their private conversation.
Like most of the fields on the mountain, this one was covered in long, uncut
grass with splashes of flowers scattered around.
Checking one last time to make sure they weren’t followed by say, a curious
Luffy, Makino took a seat on the ground, beckoning with her hand for Ace to
copy her.
Lowering himself onto the grass, Ace sat cross-legged, his body stiff as a
board, while he waited for Makino to explain what was happening with his body.
Sensing his discomfort, Makino gave a reassuring smile that did nothing to calm
Ace’s erratic heartbeat before finally speaking, her voice warm and kind.
“Ace, let me start by asking you one simple question. Are you aware of the
three secondary sex characteristics that people eventually change into?”
Licking his dry lips, Ace nodded. “Yeah, people either transition into being an
alpha, beta, or omega, right?”
“Yes, that’s exactly right!” Makino said, nodding enthusiastically. “In fact, I
am a beta, but you Ace, are an alpha.”
Eyes widening, Ace gaped back at her. “R-really!? How can you be so sure?”
“Well . . .  even though I only caught a glance, if you pair that with what
Luffy told me before I found you then there are several things that lead me to
that conclusion,” Makino admitted, a small blush coating her cheeks.
Knowing what she was hinting at, Ace flushed further in embarrassment, heat
burning brightly on his cheeks and ears. He was never gonna live that down, was
he?
“O-okay, and what are those things exactly?”
“From what I know about alphas, they all go into what is called a rut once
every two months. During this short period, they grow more agitated and
aggressive unless they find themselves a mate to relieve this . . . frustration
with,” Makino explained.
“F-frustration?” Ace stuttered, not sure what to make of the word and the
implications of it.
“Err, yes. This frustration is caused by their need to mate with someone and
have that person bare their young. However, to do that properly, they would
have to knot someone, hence the ring-like thing that was around your penis,
that’s the knot,” Makino elaborated further, her eyes ducking away from Ace’s
petrified face.
If it were anyway possible, Ace’s blush darkened an even deeper shade of red at
the mention of the stupid, mortifying, incident from earlier. For as red as he
was, there was no way he was even human anymore. He was a strawberry, plain and
simple.
Not able to withstand anymore embarrassment, he turned to try and escape but
was stopped by a surprisingly strong grip.
Blinking at the sight of Makino’s small hand wrapped around his forearm, Ace
turned his head to face her.
“Ace, sweetie! There is no need to be embarrassed! All alphas go through this,
it’s just your bodies way of telling you that you are physically ready to find
a mate. Really, it is the most natural thing in the world, so please sit back
down,” Makino said, her voice calm even though her face told Ace that this was
more of an order than a mere suggestion.
Slowly sitting back down, Ace tried distracting himself from this conversation
by playing with some of the long, bright green grass that surrounded him.
Pulling at one of the slippery strands, Ace couldn’t help but think that it
felt almost rubbery in texture.
Almost like how Luffy’s skin felt.
Ace was so caught up thinking about Luffy that he missed whatever Makino was
trying to explain to him.
All he could focus on was the thought of Luffy and his smooth , rubbery , skin
that Ace wanted nothing more than to touch right now. Where had Luffy run off
to again?
“Ace! Are you listening?” Makino asked, her face twisting in frustration.
Gulping, Ace paled at the tone in normally soothing voice. “Ah! Yeah, I’m
listening,” Ace lied, finally looking up from the ground to spare a sheepish
glance at Makino.
Makino hummed, her face and voice mimicking the doubt that she felt.
“As I was saying, you’ll need to start training to control your urges so that
when this happens again in two months, you can deal with it better. Thus
avoiding any potentially life changing consequences,” she said, brushing a
piece of her dark green hair from her face and tucking it behind her ear.
“Of course. But how can I do that?” Ace asked, crossing his muscled arms over
his broad chest.
He wasn’t exactly sure about what Makino was trying to get at since he got
distracted, but he figured it was better to play along. He did notwant to find
out what she was like when angered.
“Well, unfortunately, I can’t really help you there, since I am a beta and not
an alpha. But your grandpa Garp is an alpha so when he stops by next I’m sure
that he can help you,” Makino explained before standing up, brushing off her
long skirt.
Ace’s nose crinkled in disgusted as he physically blanched at the mere idea.
Likehellhe was going to go to that crazed, marine-obsessed monster for help. He
would just deal with this on his own.
After all, he had done things perfectly fine by himself before, so why not just
do it again?
Surely nothing bad would happen if Ace didn’t go to Garp for help. After all,
most of the time, bad stuff happened if you wentto Garp. So by that logic,
avoiding Garp’s help was the best thing to do.
“Thanks for explaining Makino, this has really helped me,” Ace said, even
though he had missed a good portion of what she had been trying to explain to
him.
“You’re welcome Ace! I’m glad that I could help you. Going through the change
can be a scary thing and it’s better if you have someone to help you through it
rather than do it by yourself. So if you ever need to talk with me again, don’t
hesitate okay?” Makino said, patting Ace on his shoulder in an attempt to
reassure him. “But I still recommend that you talk with Garp-san when he visits
again. He’s the one that can help you the most since he is an alpha too.”
“Yeah, I’ll talk with him next time he’s here,” Ace lied again as he followed
Makino back towards the house.
If he was lucky, perhaps Garp would remain a no show and taking his
grandfather’s track record into account, Ace was fairly certain he would live
Garp-free for a while.
If not a while, Ace just hoped that Garp stayed away long enough for him to get
his new status as alpha under control. That way, he could completely avoid
having to potentially go to Garp about learning how to be a proper alpha.
After all, if Ace fixed the problem there would be no need to go to Garp!
Here’s to hoping.
 
***** Best Intentions *****
Chapter Summary
     He never wanted this to happen. . . .
Chapter Notes
     Merr, I'm back again! Anyway, I'm almost positive that one day I'll
     come back and rewrite this story when I'm a better writer but until
     then, I hope this isn't terrible!
“. . . an alpha’s mating bite is significant in how it can bind two mates
together. During intercourse, they will sink their canines into their mates
levator scapulae muscle, which then releases a unique chemical that forever
connects the pair. Once the bite is given, the two can never be unmated and if
an omega or beta were to receive a mating bite from another alpha, it would be
ineffective.”
===============================================================================
One week or rather, one hundred and sixty-eight hours of hell alone on the
north most side of Mount Colubo. It was during this agonizingly long period
that Ace’s sanity wavered under the stress of a maddening arousal and intense
agitation, all thanks to his rut.
To say that it was hard to endure, especially when he knew that relief was only
a few miles away, would be a gross understatement. Nevertheless, as much as he
would have lovedto run back home, he knew that help could only come from one
person, Luffy.
Still, as determined as he was to not harm his little brother, Ace had allowed
himself to envision what it would have been like to mate Luffy; to pull him
into his arms and dominate him, ravage him until his small body displayed all
of Ace’s pent up desires. . . .
However, he was resolved to deal with his rut by himself and thus, Ace had
simply hunkered down and let nature take it’s course until seven days passed
and it finally subsided.
When all his frustration had melted away, Ace was struck by the relief of
simply feeling like himselfagain after all those hours feeling like a
disgusting monster who wanted nothing more than to ruin his relationship with
the one person he couldn’t live without.
That being said, no one could blame him for being naive enough to think that
this beast wouldn’t resurface again within two months time, but as much as he
wished he didn’t have to deal with the dreaded rut, Ace didn’t get a say in the
matter.
Nature and genetics could not be ignored.
As such, Ace continued to deal with his rut (alone) before like a bad
nightmare, it would fade, leaving only the remnants of distorted feelings
behind him. After which he would trudge back to Dadan’s, thoroughly spent and
in serious need of a proper bath.
Back at home, Ace was welcomed every time by Luffy, all smiles and rubber skin,
who would promptly tackled him to the ground in a fierce, octopus like hug
before releasing him.
After that, Luffy would ask Ace if he was finally feeling better (Ace doubted
Luffy actually knewwhat he was dealing with every two months) and if he had
caught anything interesting during his time away.
His responses were usually kept short and simple until he could direct the
conversation elsewhere and this quickly became the routine Ace would deal with,
with each passing month.
The only thing that could have possibly thrown a wrench into Ace’s slowly
stabilizing world would have been the appearance of Garp. However, as days
blend into months, his grandfather continued to remain a no show. Honestly, it
was like he didn’t care about Ace or Luffy at all.
As such, Ace probably shouldn’t have been so thrilled that he got to avoid
dealing with the bull-headed marine but he’d be lying if he said that he
wasn’t.
Now a year later, with Ace having his status almost completely in control, life
had basically returned to how it had been before his transition, which meant
sparring session with Luffy.
Like today for instance, the pair of them were enjoying one such, worry free,
alone time as they battled for the tenth time that sunny afternoon.
Covered in a thin layer of sweat, the two of them continued to compete in the
old clearing that they and their late brother, Sabo, had used to train in.
Over the long years without him, the area hadn’t changed all too much: the
trees that encircled the area still stood as tall as they had six years before
and the ground, covered in patches of dirt and grass, was for the most part,
unchanged.
Hell, even their old wooden score board was still standing over to the side, a
little more weather worn sure, but it still looked like it had when Sabo used
it to keep score. Not that this came as a huge surprise for the remaining two
brothers, because keeping score this way had always been more of Sabo’s thing.
That and the fact that they didn’t want to remove the faded numbers that were
in their brother’s familiar handwriting.
To be honest, Ace at one point had wanted to take it down that that they could
store it somewhere safe, that way rain and wind wouldn’t wipe away the last
remaining mark of Sabo but Luffy wouldn’t hear of it.
“We have to keep it up,” Luffy had said, standing resolute with his arms spread
wide in front of the scoreboard. “So Sabo can keep taking score!”
After that, Ace never tried to remove it again so thus it stayed to keep the
area as it was when they had first found it. All in all, it appeared that the
only things that hadchanged were Ace and Luffy themselves.
Of course, that was only natural as they continued to age and mature throughout
the years. Although, Ace had changed a lot more than Luffy since they were
children.
After going through puberty and his transition into an alpha, Ace had grown
both in body and in strength. At sixteen, he now stood proudly at five feet
eleven, but from the familiar pain in his muscles, Ace knew he hadn’t finished
growing and was positive that in a few years time, he would be well over six
feet.
Thanks to his intense training and physical fitness, Ace’s muscles became
steadily more defined until he could proudly show the six pack he now sported.
However, unlike his brother, Luffy hadn’t really changed all that much since he
was seven years old.
Sure, he had grown taller and had (admittedly) gotten stronger, but he was
still the scrawny brat that Ace had first met all those years ago, back when
his heart was full of bitter hatred and unaware of the love that could exist
there.
Although, if Ace were being honest, he thought Luffy’s short stature and skinny
limbs suited him far better than the tall, muscled body he continued to strive
towards. So he wasn’t all too concerned about Luffy’s lack of change since he
was still basically a child.
After all, Luffy was only thirteen, he still had many years to grow so Ace
wasn’t all too worried about it.
What he was worried about was Luffy’s sudden lack of energy.
They hadn’t been sparring for more than a good, fifteen minutes and yet, Luffy
was even more sluggish than he was when they finishedtheir little competition.
Not only that, but he was flushed and coming down with a fierce sweat: his
whole body dripping in the salty liquid.
Frowning at the worrying sight, Ace slowly relaxed his body before lowering his
fighting stance. “Lu, let’s stop for today,” he said, hoping that by using
Luffy’s nickname he would be more willing to cooperate.
However, with Luffy’s resounding whine, he knew that it hadn’t worked. “But
Ace, I was so close to beatingyou today!” Giving another halfhearted groan,
Luffy slumped to the ground before resting his flushed body against the thick
tree behind him.
“Sure you were,” Ace humored back, shaking his head at him. “Now let’s head
back to Dadan’s so Dogra can check you over.” Taking a step forward, Ace began
walking over to Luffy who let out another pain-filled groan.
“A-Ace, I t-think that you’re right. My body feels reallyhot,” Luffy whimpered,
lifting his large and slightly dazed brown eyes to look up at Ace who frowned
in return.
“See, I knewyou were getting sick. Now come one, let’s go—”
Ace’s voice cut off as he stopped dead in his tracks. Coating the warm air of
May was an intoxicating smell that made Ace’s body tingle all over in pleasure.
It was pleasantly sweet, yet something so much more than that and it was
callingto Ace.
Dropping to his knees, Ace crawled towards the scent until he was pressed
against something smooth, almost rubbery in texture, and slightly damp.
“Nghh, Ace? What are you doin’?”
What washe doing?
Shaking himself out of the daze he was quickly following Luffy into, Ace pushed
himself away from Luffy’s neck, clenching his fists tightly.
That familiar fire in him seemed to have sparked itself anew but was burning
brighter than ever and all he knew was that the sweet smell was coming from his
little brother and it encompassed him entirely, almost as though it were
replacing the blood in his veins and he was drawn to it and he was definitely
losing this fight.
He looked at his brother on the ground then, the flushed form of his body
twitching and writhing in pain and he felt helpless, because he didn’t know how
to help Luffy when he wasn’t sure what this new part of him intended to do.
He gripped his fist, determined to help Luffy, but just taking one step closer
had him incapacitated with the scent. His teeth ground together and he
squinted, trying to see through the haze because what wasthis? Why was his body
so uncontrollable?
Even his unbearable ruts had never been this ferocious!
“A-Ace!” Luffy choked out, reaching out to him. Ace’s heart broke because Luffy
was dying wasn’t he? He got sick somehow, some sort of bug, and now he was
actually dying and Ace couldn’t even do anything?
Like hell!
Ace growled, something wrecked and feral, and crawled back to Luffy, wrapping
his arms around him as he intended to pull him up off the ground, when suddenly
his vision was red and there was a painful (yet, familiar) throbbing in his
pants that he was vaguely aware of.
He couldn’t think, and all rational thought was pushed to the back of his mind
as he was forced to give the reins over to the entity that dwelled deep within.
“L-Luffy,” he croaked, pressing his face into Luffy’s neck, unable to stop
himself. The scent was callingto him, and he was a slave to it. This was the
way it was supposed to be.
He was going to save Luffy.
“Ace . . . Ace w-what are you—”
“Don’t worry, Luffy,” Ace said reassuringly, whispering into Luffy’s ear. “I’ll
take care of you.”
“A-Ace. . . .” Luffy whispered, voice filled with lust as he pressed back into
Ace who had no idea whether it was intentional or not, but either way, he
somehow knew what it meant.
He didn’t waste any time ripping their shorts off and getting their skin back
into contact with each other, even though he didn’t really know why this needed
to happen, but it did, and his cock was absolutely throbbing, but he knew this
was somehow what Luffy needed.
The boy’s ass was dripping with some sort of viscous substance that was the
source of the sweet smell, and Ace buckled under the onslaught of it all; his
senses overloaded, and just like that what was left of his rational thought
seemed to leave him.
He pulled Luffy back against him by the arms after flipping him onto his
stomach, not quite sure why, but he needed to be closer.
Direct skin contact wasn’t enough either.
Ace panted, delirious with the intoxicating smell and he collapsed over Luffy’s
body, rutting against his ass, and it felt so good, sogood, but it wasn’t
enough. Luffy was still in pain and, at this point, Ace was too.
He felt his dick catch on something, and it sparked something in his mind from
an obscure place, and he tried to recreate it.
He rubbed a certain way and it caught more this time. He growled and pushed,
his instincts telling him to do so, and it wasn’t long before he was encased in
a tight heat, slick and sucking and he gripped Luffy’s hips tightly, vaguely
aware of the labored breaths coming from the younger boy, a distant mantra of
his name just missing the barely lit flame of his consciousness mind.
The moaning, however, rang loud and clear. It told Ace that, whatever he was
doing, this was correct.
Ace thrust into that heat, the heat of Luffy’s body, over and over again;
harder and harder. It was a dizzying sensation as the smell only grew and he
couldn’t think, he couldn’t even see through the haze of red euphoria.
The throbbing in his dick grew and it felt good. It felt right. Luffy was going
to be okay. Ace was going to protect him, was going to make him his.
He could vaguely feel Luffy slump onto the ground, and he held him from behind,
pressing his face into the back of his neck.
It was everything it was supposed to be and he couldn’t help but sink his teeth
into the rubbery skin there as he thrust harder, giving Luffy everything he
needed. The boy pressed back into him, a deep moan erupting from his throat. He
could feel that tight heat clench around him and it was perfect.
“L-Luffy.” He could feel the words come out of his mouth as suddenly everything
was so much tighter, so much harder, and his movement was impeded.
He was losing it. Something was happening and It was filling his mind with
sparks. He was locked inside of Luffy by something, but that was fine.
This was how it was always meant to be.
As he started to come, the haze in his mind cleared and he was vaguely aware of
what was happening. He bucked and rutted into Luffy as he came, unable to fight
the instinct. It was overwhelming and it lasted for what seemed like ages
before he was level headed enough to realize what he’d just done.
He tried in vain to pull away, but he was effectively locked with his damn knot
stuck inside of Luffy.
Said preteen was slumped to the ground, chest rising and falling, but he didn’t
seem to be doing that awful twitching anymore, which was good. Ace looked
around, noticing just how open this place was, and everything in him was
telling him to fucking move already!
He tried to shake Luffy awake, but the boy was fucking napping of all things!
He felt another spasm overtake him, and it was a moment of another very intense
orgasm hitting him like a ton of bricks and he filled Luffy up impossibly more.
Luffy merely sighed beneath him, a snot bubble growing disgustingly and Ace’s
eye twitched.
“S-Shit!” When it died down, Ace wrapped his arms around Luffy’s middle and
picked him up, looking around warily as he hobbled away to find cover within
the trees.
Protect Luffy, protect Luffy. The mantra continued in Ace’s head as he stumbled
awkwardly through the dense growth of trees, looking for a safe place to
continue whatever thiswas.
If Ace hadn’t been so worried about keeping Luffy safe, maybe it would have
registered that he was walking butt-naked through the forest with his little
brother strapped to his penis. But as of now, he was only worried about finding
a suitable place to take care of Luffy.
Glancing around with desperate eyes, Ace realized with a start that this part
of the jungle was vaguely familiar to him. The moss covered trees looked
exactly the same as the thousands of others throughout the forest but the one
in front of him was much larger than the rest.
Looking up from his spot on the ground, Ace finally saw what made this place so
familiar; the old wooden tree fort that Ace and his two brothers had made many
years ago, which had somehow survived years of neglect.  
It would be a perfect place to keep Luffy safe, but how the hell was he
supposed to get them up there?!
His knot still hadn’t receded so pulling out of Luffy to climb the huge fucking
tree was a pipe dream, but they weren’t safe in their current state. Growling
in frustration, Ace pulled at his hair while his other hand tightened his grip
on Luffy who was still fast asleep.
How in the hellwas he supposed to do this!?
If Luffy were awake, then he could hold onto Ace while he made the climb up the
tree. Seeing as how Luffy was still unconscious then that plan wouldn’t work.
Or maybe, it would.
Slowly lowering himself onto the ground, Ace grabbed onto both of Luffy’s limp
arms and pulled them around his waist before tying them together, thankful for
the first time in his life that Luffy was a rubber man.
Satisfied with the strange bow of limbs, Ace stood, ready to get Luffy to
safety. Kicking off his shoes, Ace grabbed onto one of the many dark-green
vines that were wrapped around the large girth of the tree and began his climb.
After what seemed like an eternity, Ace finally made it to the top and to the
long abandoned tree house.
Inside the familiar fort, a fine layer of dust and dirt covered the wooden
floor and a few vines covered the exterior. Nature always seemed to find a way
of taking back the land if left alone.
Stepping inside and sitting down, Ace was relieved that there were at least
some blankets that he and Luffy had left when they went to live with Dadan
again. Sure, they weren’t in the best condition after being exposed to the
elements for so long, but they would do.
All they needed now was some food and water and they’d be set. But Ace would
worry about that later, right now he just wanted to rest and figure out what
thehell just happened.
“Nhgg. . . .” Luffy groaned, finally stirring himself awake from the slumber he
had fallen into upon his climax.
Seeing this, Ace couldn’t help but let out a breath of relief that Luffy was
finally awake, because it meant that what he did to his little brother had
helped him instead of possibly killing the small thirteen year old. Said
teen was still unaware of Ace as he stared dully at his new surroundings, not
quite awake enough to comprehend the change in scenery.
As Luffy glanced around himself at the rundown room, something finally seeming
to click in his sleep-fogged brain that this was notwhere he remembered being
last.
“Wha—where am I?” Luffy asked, leaning against the warm, muscled wall of flesh
behind him only to try and jump away from it in surprise before relaxing at the
familiar sight before him. “Ace? What’s going on, where are we?” Luffy
questioned, staring up at Ace with his large brown eyes.
“We’re in our old fort—you know, the one we made together with Sabo?” Ace said,
gesturing to the rather small, shabby looking tree house that they were in.
Luffy hummed to himself for a minute before something finally seemed to click
in his head. “Ah, I remember!” Luffy exclaimed, smiling happily before
confusion spread across his face. “But . . . why are we here?”
“Cause we needed to be somewhere safe.”
“Why?” Ace’s right eye twitched, trying his best to keep his irritation from
rising.
“Because I wasn’t in the best state to protect you.” Luffy tilted his head to
the side, the need to ask more questions practically written all over his face.
“Wh—”
“JUST BECAUSE, OKAY! Now please just stop with the questions already,” Ace
pleaded, pressing his forehead to Luffy's, which was suddenly very warm,
toowarm in fact.
Ace, worried about Luffy possibly being sick again, pulled away from him and
starred in a transfixed horror as he realized that what happened earlier during
their sparring session was happeningagain.
Luffy’s small frame was already flushed entirely in a varying shades
of crimson, staining his cheeks bright red and his body in a pink hue.
Dammit, that godawful twitching was back and Luffy’s eyes were quickly glazing
over as what seemed like an intense heat fogged his mind.
Taking in a large whiff of the air, Ace too could feel his mind numbing as he
continued to smell that intoxicatingscent from before. It was filling the
entire room and Ace was barely aware that this was probably a bad thing.
No. It was most certainlya bad thing.
Whatever this thing was, it washurting Luffy and causing Ace to do something to
him, his preciousbaby brother, that he hadn’t wanted to do since Ace had first
transitioned into an alpha.
Ace wanted—no, he needed to fuck Luffy but there was no wayhe was going to let
his primal urges control him again. Once was already too much and he would
never be able to forgive himself if he took advantage of Luffy any more than he
already had.
Of course, that meant that he had to hurry and get outof Luffy before what was
remaining of his conscious mind left him. Knowing this, Ace scrambled to try
and quickly untie Luffy’s rubbery arms which were still securely tied around
his waist. Tugging at the strange bow that he had made, Luffy’s arms came free
and zipped back into their normal, human-sized, lengths.
With his arms free, Ace’s trembling hands gripped onto Luffy’s slim hips,
disregarding the fact that mere minutes ago, his stupid knot had been keeping
him from removing himself from his little brothers ass, and pulled.
Instead of merely jerking Luffy, his warm body slid up Ace’s cock, no longer
impeded by the fleshy ring because apparently, Ace’s knot had receded a long
time ago. Not expecting the sudden, antagonizing, squeeze on his overly-
sensitive penis, Ace only did what his body felt right: he slammed Luffy down,
plunging his dick back into that deliciously warm, wet heat.
“NGAH!” Luffy screamed, his voice a mixture of surprise and arousal, as his
shaky hands gripped tightly at Ace’s muscled thighs before he turned his body
to fully face the older teen. Pink lips quivering as he tried his best to form
words, Luffy looked up with big, uncertain eyes. “A-Ace, wha did you jus’ do?”
he asked, lifting one hand to weakly tug onto Ace’s arm.
Flushing in shame, Ace refused to meet Luffy’s eyes. He knew what he had just
done and he was perfectly aware that what he was doing, regardless of the fact
that doing this had helped Luffy last time, was wrong.
Placing his head against the back of Luffy’s flushed neck, Ace could feel salty
tears prickle at the corners of his eyes as a deep, conflicted frustration
churned inside him.
While fucking Luffy had so far proven successful in helping the thirteen year
old fight whatever he was sick with, it didn’t change the fact that Ace was
basically rapinghim. Ace knew just by looking at Luffy’s dazed, chocolate brown
eyes, that the small boy could barely think, let alone consent to having sex
with Ace, his sixteenyear old brother.
However, Luffy was getting worse and if Ace didn’t do something, Luffy might
actually die.How could he not? It looked like his small body was going to
destroy itself if Ace didn’t help.
Tightening his grip on Luffy’s hips, Ace finally raised his head, a fierce,
determined glint in his eyes. There was no way he was just going to sit around
and let Luffy deteriorate when he could help him.
“Luffy, you can hate me when this is over, but until then, I promise, I
willtake care of you.”
Ace wasted no time in keeping that promise.
Lifting Luffy’s round hips, Ace slowly brought them up again before bringing
them back down; the wet, squelching sound caused by Luffy’s slick bouncing
across the thin wooden walls of the fort as he did.
Slowly setting a faster pace, wanting to quickly get this over with, Ace’s
nails dug into the soft, warm skin of Luffy’s hips, desperate to keep his grip
on the much smaller males sweaty body.
“Ah! Ace, please!” Luffy begged, large and wet salty tears spilling freely from
his eyes as he continued to bounce on Ace’s hard cock.
“What Luffy?” Ace asked by Luffy’s ear, his voice almost husky, causing a
shiver to run down Luffy’s spine. “What do you need?”
“I NEED ACE!” Luffy said, his sweet voice breaking. Ace growled at Luffy’s
pathetic plea and quickened his already rough pace, baring no mind to the pain
that Luffy would feel once this was finally over.
“GodLuffy! You’re so tight!” Ace groaned, slamming his own hips up to meet
Luffy’s.
“Mmm, AH! Ace— something's happening." Another moan spilling past his lips,
Luffy's blunt nails clawed at Ace’s thighs as he felt a pressure quickly build
in his lower belly.
“Shit, I know! I’m so close, ” Ace hissed, his grip on Luffy tightening
painfully more. He was barely aware that him doing this would end up leaving
dark bruises on Luffy’s, until now, unblemished tan skin.
As Ace hastily neared his peak, his until now, rough and fast pace, became
erratic as the pleasure pooled into his stomach and hummed from underneath his
heated skin. Giving a few more sloppy thrusts, Ace found his teeth seeking the
spot on Luffy’s neck that he had marked before and felt them sink in as he
came.
Luffy let out a choked scream when Ace’s sharp canines pierced his sensitive
flesh, coming immediately after; spurts of pearly white cum shooting from the
tip of his neglected length. Thoroughly spent, the rubber teen let his body
slump back against Ace, the twitching gone and the heat finally receding. It
appeared that for now at least, he was okay.
Ace let out a sigh of relief as the realization of this settled in as his own
exhausted body fell back onto the scattered pile of blankets, pulling Luffy
with him.
“Ace m’ tired,” Luffy said quietly, rubbing his sleepy brown eyes.
“I know Lu,” Ace replied, turning them so that they were both laying on their
sides before he placed his right arm under Luffy’s head, his left arm wrapping
itself securely around Luffy’s waist. “Let’s go to sleep.”
“Mmm . . . okay.” Eyes fluttering close, Luffy fell into a blissful sleep, Ace
following almost immediately after.
They continued sleeping until the sun began to dip down, casting a warm-orange
glow across the island and a small fort built in a tree. Ace awoke first, his
body sore from laying in one position for so long and sticky from all the
strenuous activitieshe had taken part in with Luffy.
Gingerly sitting up so that he could stretch his aching muscles, Ace’s sudden
movement caused a whimper to escape from Luffy’s mouth as he slightly moved
away from him.
Ace felt bad for causing Luffy any added discomfort but dammit, he needed to
take a piss.
Standing, he wobbled a few times until the feeling finally returned to his legs
and walked outside and over to the edge of the fort. After relieving himself,
Ace walked back inside and waited for Luffy to wake up.
He thankfully didn’t have to wait too long before Luffy awoke, grumbling as he
did. Ace helped Luffy sit up since the small teen looked far too sore to do it
on his own.
“Hey Lu, how you feeling?” Ace asked gently, his hand rubbing up and down on
Luffy’s back, trying to ease whatever discomfort that he may have caused. Luffy
let his worn-out body lean against the strong body of his brother, his
exhaustion still present in his movements.
“I’m sore,” Luffy began, licking his lips, “and thirsty.”
“How about I go and get us some food and water, how does that sound?” Ace
offered, giving Luffy a small smile.
Luffy nodded in reply before he turned and wrapped his thin arms around Ace,
tucking his head under Ace’s chin as he did. Ace returned the hug and then
tried to stand but Luffy’s grip held surprisingly strong, considering how tired
the small teenager was.
“Come on Luffy. I can’t go and get the stuff until you let go,” Ace said as he
tried in vain to pull away from him.
“But,” Luffy began, his large brown eyes looking up towards Ace, “I don’t want
you to leave.” Ace felt his heart nearly stop by just how cute that was. His
cheeks growing hot, he buried his face into Luffy’s neck, unwilling to let go
even if it meant they would starve to death.
No!
Ace was supposed to be theresponsible, older brother and he had made a promise
to himself, not to mention Sabo, that he would protect Luffy. Right now, Ace
needed to go get food and water, even if that meant leaving Luffy alone whilst
he did.
Ripping himself away from hisridiculously cute younger brother, Ace ran towards
the door of the fort, yelling that he would be back soon as he did.
Scrambling down the tree, it wasn’t until Ace finally reached the bottom that
he noticed something crucial to his health as well as his dignity.
He wasn’t wearing any pants.
Ace felt his face warm as a deep scarlet blush covered the upper part of his
body as he took in his unclothed form. He had never felt so . . . exposed in
the entirety of his sixteen years. Not to mention, him lacking pants hadn’t
occurred only once today, but twice.
God, embarrassment didn't even begin to cover how he was currently feeling.
However, he didn’t have the luxury to worry about his lack of undergarments
right now. The sun was setting and if Ace didn’t hurry and procure some food
and water fast then he would have to wait until tomorrow morning. Knowing
Luffy’s ridiculous appetite, not to mention his own, neither brother would
survive if they had to wait.
So, as much as Ace wanted to go and retrieve his and Luffy’s discarded shorts
from earlier, he simply didn’t have the time.
Hunting while butt-naked was an experience Ace knew that he would never forget,
but it thankfully ended in success with Ace killing a large bear and having
found some water for him and Luffy to drink.
By the time Ace finally made it back to the tree fort with his kill and the
makeshift water bottles he had made out of leaves, the sun had disappeared. In
it’s place stood a full moon and a black, star-filled sky, which gave Ace a
small amount of light that would help him make the climb back up the tree.
Not surprisingly, carrying Luffy was much easier than carrying the black bear
but Ace still made it back up towards the fort.
Stepping inside their makeshift home, Ace had time to set down their meal and
the water before the scent from before punched him in the face.
“ACE!” Luffy called, his flushed body spread out on top of their makeshift bed,
waiting to be filled.
It looked like eating would have to wait.
As the hours passed, a pattern in their activities emerged. They would have
sex, pass out, wake up and have sex again, take short breaks to try eat and
drink something (not much though), and then finally get right back to fucking.
At one point they had even made their way down towards the river for a much
needed bath after both of them started to chafe from their dried cum. Now
thathad been an interesting experience.
By the evening of the second day, after almost non-stop sex, Ace was exhausted.
He had never known he could feel this tired and worn out and was weak enough to
admit that he wished he had never learned in the first place.
Honestly, Ace seriously felt bad for the people who had sex for a living,
because it hadn’t even been two full days yet and he was already nearing the
end of his rope. Despite that, it appeared that Luffy was basically unaffected
and was ready to continue for another two days.
Ace almost wanted to cry.
Thankfully, right now Luffy was asleep, the small male having passed out a
minute after he came, screaming Ace’s name. Which meant that for a short while
at least, Ace had some much needed reprieve.
Climbing down from the fort, thankfully this time with shorts on, Ace stretched
his arms and gave a relieved sigh. It was a nice change to get out of that
stuffy tree house for a bit and with the weather today being so nice, he
decided that a walk would do him some good.
Walking away from the fort, not really caring where his feet led him, Ace let
himself enjoy the peace and quiet for a moment, not sparing a single thought
that maybe, he shouldn't have left Luffy behind.
