****** Percy Jackson and the Heir of Hades ******
by gmartinez12
Summary
     Percy needs some alone time to do what all boys his age do but he
     forgets to lock the door…and gets an unintentional audience.
Notes
     Okay so my friend just recently introduced me and got me EXTREMELY
     addicted to the Percy Jackson Series. Like, oh my gods, why haven't I
     been reading this when I was a kid?? I've read like the first 5 books
     in 4 weeks. So naturally, as with most things I love, I made a smutty
     fic about it! XD So, this one features Percy and Nico, my fave gay
     ship right now, during the early parts of The Titan's Curse, Book 3,
     just after they rescue Nico and Bianca but before they leave for the
     quest. Let's pretend they had a couple of days of rest and fun first,
     which is where this takes place haha. So disclaimers and stuff apply,
     Percy is 13 and Nico is 10 in this chapter. Gods, I'm never gonna get
     used to writing 10 year olds haha, I cant wait for the next chapter
     where I can write them a bit older ;)
     I hope you enjoy my first ever PJO fic!
Going to Camp Half-Blood was great if you were a kid who just happened to be a
demigod that had to fight monsters every other day. It was not great, however,
if you were a kid going through puberty.  It turns out that being the son of
Poseidon, one of the big three gods, didn’t give me any extra powers to make
extra hard and embarrassing problems below my belt magically go away. And when
you’re in a summer camp composed of dozens of young demigods, nature spirits,
satyrs and whatever else, getting some privacy is a challenge.
“Hey, Percy, aren’t you joining the sing-along?” Beckendorf, one of my friends
from the Hephaestus cabin, called out.
 I shook my head apologetically. “I’m beat. I think I’ll go to bed early for
now.”
I felt bad having to lie to Beckendorf. If I’m gonna be honest. I’ve been
having a serious case of random hard-ons the whole day, and if I didn’t get to
take care of it, I felt like I’d go crazy. Thankfully, it was winter, and there
were fewer campers this time of the year. There were only the year-rounders who
stayed at camp because they had nowhere else to go. The bright side is, I can
have a bit more privacy in my own cabin without having to think about anyone
bothering me.
From the head table, ten-year-old Nico Di Angelo shot me sad look. Together
with his sister Bianca, he was a new demigod that my friends and I had just
rescued from monsters a few days ago. We’d taken them to the camp for their
protection, which was why I was here even though it was winter.
 “Aw, can I come with you, Percy?” Nico asked with puppy dog eyes. I can
understand why he wanted me to stay. Aside from his sister and me, he barely
knew anyone at camp.
I shook my head again. “Sorry, Nico. It’s not like you can go to bed with me.”
He pouted, but he didn’t press any further. While I really did feel sorry for
the poor kid, I definitely couldn’t take him with me—especially not after what
I planned to do.
I headed to cabin number three, the cabin reserved for Poseidon’s kids, which
totaled to…just me. I closed the door behind me as I excitedly stripped off my
jacket and jeans, until I only had my orange camp t-shirt on and my white boxer
briefs. Thank the gods I had to cabin to myself. I really needed the privacy,
the way only thirteen-year-old boys like did.
I lay on my bed and breathed a sigh of relief. Probably because it was
dedicated to the sea god, the cabin always felt like it had a mild breeze
passing through, smelling vaguely of the open sea with a hint of brine. Beige
light softly reflected off of the limestone walls from shell-shaped lamps.
Everything in the cabin seemed like it was inviting me to relax, and I’d
planned to do just that. I was definitely going to take my time.
I began to rub at the front of my boxer briefs, addressing a prominent bulge
that had been aching for attention all day. I groaned in delight as my palm
rubbed faster. My crotch was beginning to pulse with that familiar surge of
excitement, and I couldn’t help but roll to my side and thrust out my hips.
People kept telling me how I’d grown taller these past few months, but what no
one ever saw, and what I was actually more proud of, was how much of me had
grown inside my underwear. I finally slipped them off and just let myself enjoy
the feeling of being completely naked from waist down. The sheets felt cool and
comfortable on my bare butt, and my rod twitched in delight as it finally
tasted the sweet air of freedom.
I was pretty sure that I was five inches long, maybe a little more. My bell-
shaped tip was flared and pink, ready for some much needed fun. I gripped my
shaft and pumped slowly but firmly, and each time my hand pumped down I’d feel
the short wiry hairs at the base—I think I grew a little bit more of them in
just the last month. When I first started sprouting hairs, I just thought they
were annoying and sometimes itchy. But when I got more, I began to like
them—they kinda made me look bigger, or manlier, if that made sense.
“Mhhhm…” I hummed.  In the privacy of my cabin, I could’ve moaned loudly if I
wanted to, even though I never did. When I’d first learned how to take care of
my private business back in my room at my mom’s apartment, I had to be quiet. I
guess you could say that I trained myself to not make a sound, even if right
now, no one would ever hear me.
I stroked up and down, slow and steady. I got harder and stiffer with each
passing second. My breathing got ragged and a bead of sweat rolled down from my
forehead as I stroked myself again, and again. I’d realized early on that
trying to ignore this new and urgent need of mine never worked. I always had to
take care of it, somehow. I needed to let it out, to let myself go, to let
myself just enjoy. Each pump was a warm waves of sensation spreading from my
groin to every inch of my body. I closed my eyes and curled my toes as I
stroked faster.
All demigods had some kind of ADHD. But whenever I was doing this, it’s easy to
forget that I ever had it. I’d become so focused with making myself feel good
that I’d actually stop being aware of everything else. I didn’t know that my
hair was already plastered to my forehead with sweat, nor how long I’d been
doing it, nor the way I’d subconsciously been moving and shifting around the
bed. It was like having tunnel vision—everything else was a blur as I stroked
furiously as fast I could. I was racing towards a finish line that had a sweet
and pleasurable payoff. I was excited and eager—I wanted it really bad.
It’s never good when you start wanting something ‘really’ bad. You tend to not
notice things that are actually ‘really’ important…like say, the ten-year-old
boy who’d just come into the cabin and was now staring dumbfounded at you with
your rod in hand.
“Nico!” I jolted upright with a mixture of surprise and embarrassment. I tugged
at the sheets to cover my crotch but they wouldn’t come off, so I yanked my
shirt downward instead to hide whatever scrap of dignity I had left. It didn’t
help much—the shirt couldn’t cover my exposed nutsack. “What are you doing
here?
Nico Di Angelo stared wide-eyed at me. Specifically, he had his eyes on my
shirt-covered crotch, which had a small wet spot where my tip had grazed the
shirt. His tiny frame was stock still, his arms frozen in place and there were
trading cards scattered on the floor—he must have dropped them in his shock. He
was wearing a pair of black shorts that were cut off just above his knees and
an orange camp shirt just like mine, except it seemed like it was two sizes too
big for him.
“Nico!” I hissed again when he didn’t answer. As an afterthought, I pleaded,
“The door!”
Nico bolted to the door and locked it. I’m pretty sure I’d have spontaneously
combusted on the spot if anyone else saw what I’d been doing. I’d actually
hoped that he’d run away altogether, but instead he stayed and turned to face
me.
His eyes were wide and his tone was almost shrill as the words came tumbling
out of his mouth. “Oh my gosh, Percy! You’re naked! Aren’t you cold?”
It wasn’t the first question that I expected. I was gearing up for questions
like why I’d had my hand wrapped around my shaft, or what exactly it was that
I’d been doing. Instead, Nico asked me if I was cold, and the childish
innocence of it all was actually kind of…cute. It was going to make explaining
things harder. Heck, it made me harder, if that made sense.
“Nico...” I began, “I was…uh, you know...jerking off…”
“What do you mean?” Nico asked again. He came closer until he was standing in
front of me. His eyes had this intense look on them. Whatever shock he’d had
before was now replaced by pure curiosity. Unlike me, who was almost melting
with embarrassment, Nico looked almost thrilled.
“I was…I just had to…aarrgh, why are you even here?” I hissed in frustration.
Nico looked down. “Well, I got bored and sis was busy talking with the hunters,
and I wanted to see if you wanted to see my Mytho Magic figures and…” He looked
up at me again and down at my covered crotch. “I mean, I was sure no kid would
ever sleep this early so I knew you were awake and maybe…doing something fun
or…”
Nico gave me this shy grin as if that was his way of apologizing. He brushed a
stray lock of his messy raven hair and continued, since I was still too
dumbfounded to reply.
“You were…you were playing with your peener,” he said in barely a whisper.
“My…’peener’…?” I asked. It felt like such a silly name for it.
“Yeah,” Nico nodded. “I’ve never seen anyone else’s before. It looked really
big…can I…is it okay if I see it again?” he asked hesitantly. He was rocking on
the balls of his feet excitedly.
I sighed. It wasn’t like I had anything else to lose at that point, and Nico
complimenting my size gave me a little bit of my pride back. I mean, I guess it
was pretty big. Maybe to Nico, it was even huge. While it was still a little
embarrassing, having him faun over me sounded pretty cool.
I let go of the shirt and it snapped back up, revealing my bare crotch to
Nico’s hungry eyes. My shaft twitched involuntarily, and I felt a surge of
warmth from my groin. I think I actually liked the attention.
“Whoa. Amazing,” Nico murmured as he leaned in for a closer look. “It has hair
on it. Is that normal?”
“Of course it is!” I chided. “It’s the best way to tell that you’re becoming an
adult!”
“Oh, cool,” Nico replied absentmindedly as he continued his inspection. “Mine
doesn’t have any.”
“Well you’re too young and—“
“Why is it so big and long like that?” He asked again as he leaned closer.
“It just happens when you grow up, okay?” I said as I squirmed awkwardly.
“Mine doesn’t get like that at all,” Nico explained. He held up his hand and
made a gesture with two fingers. “It’s only ever that small.”
He got even closer until I could feel the warmth of his breath on my sensitive
tip, making it twitch again and almost hitting the end of his button nose.
“Gah!” Nico gasped as he suddenly backed up and fell to his butt on the floor.
“S-sorry!” I blurted hastily. “It does that when I get excited.”
“Why are you excited?” Nico asked innocently. “Why were you playing with it?”
“You don’t know anything about it?” I replied. “Haven’t you ever tried it
yourself?”
Nico shook his head and stood up. “There was this one time I had to pee outside
and my sister came with me. She saw me touching it a lot even after I was done
but she said it was rude if I kept playing with it…and then there’s this other
time…”
I didn’t know why, but something about this whole scene was getting me very,
veryworked up. Here I was, naked from the waist down with my pride and joy hard
and pointing up at my belly, being stared at by Nico while he talked about his
‘peener’. I felt a nagging at the back of my head, like how you feel when you
realize you kind of want something that you never knew you wanted. Before I had
time to think of why, Nico had already gotten me weirdly curious about…well,
him.
“Hey, Nico,” I interrupted as he was about to trail off again, “can I see
yours?”
Nico cocked his head to side like he was wondering why I’d even ask that. I was
about to say I was kidding when he shrugged and nonchalantly pulled his shorts
down to his ankles, exposing his flaccid boyhood in front of my face. He pulled
his shirt up to his chest so that I had a clear view.
It was a tiny little thing and couldn’t have been more than two inches. He had
a bit of loose skin at the tip so I couldn’t see the head, and his sack still
clung tightly to his body. It was smooth and hairless and looked just the same
as the rest of his olive skin. He looked exactly like what I’d thought a
regular kid his age would, I guess. For some reason, seeing his package made me
even more excited. My rod twitched again—more urgently this time. I needed to
get myself off, and fast.
“Nothing really happens when I touch it,” Nico continued. He started tugging at
his little peener.  “It doesn’t get big like yours does, and I get tingly but
that’s about it.”
“I do it because it feels good, Nico,” I said, trying not to sound like I was
in a rush. “Playing with your…uh… peener is really fun, especially when you get
to my age. Maybe…you can have those good feelings, too? You just need to learn
how to do it right. All boys do it...mostly.”
“Wow!” Nico excitedly chirped as he beamed at me. “What does it feel like,
exactly?” His face practically glowed now, and his expression reminded me of
this puppy our neighbor owned that was so adorable that everyone that passed it
stopped to pet its head.
At that point I was really kind of desperate to get my rocks off. My crotch was
hot, my cheeks were flushed, and I felt like I was in a daze—I couldn’t think
straight. I felt like I could do anything in the world as long as I could get
myself off. Anything, without even thinking about it. I suppose that’s why I
took Nico’s little thing in my hands, and then used three fingers to stroke him
off, just like I used to do when I was just starting to learn how jerking off
worked. It helped that by now, I was strangely attracted to the idea of
touching Nico, and making him pant like my neighbor’s cute puppy.
Nico’s eyes almost bugged out as I stroked him. My other hand found his bare
butt and pulled him a little closer, and I rubbed his pert cheeks along the
way. I guess Nico liked that, because his boyhood stiffened in like, two
seconds. If I were to guess, it looked like it was three inches, and his slick
red head peeked out with every stroke. His face had this odd expression, almost
like he was trying to say ‘whoa’ but just then forgot how his mouth worked so
that it just hung open in amazement.  He whimpered like he was holding his pee
in, but I could tell he was getting into it.
“You like it?” I asked.
“Oh wow, yes!” Nico panted.
“That’s what I’m talking about,” I replied with a husky voice. “But it gets
even better from there.”
“Really? Please, Percy, keep doing it, I wanna see what’s better!” Nico thrust
his hips into my hand, his boyish impulses putting him on auto-pilot.
Nico’s face was pleading with me to keep doing it, but he didn’t have to. I was
starting to really like the silky smooth feeling of his little boyhood on my
fingers. It was incredible how hot it felt to the touch, and how it was both
rock hard but baby soft all at the same time. I could even feel little twitches
as he tried to flex his slim pole.  That and just seeing his body wriggling
with delight was an impossibly cute sight that I wouldn’t mind getting more of.
Just then, my own rod involuntarily twitched. I couldn’t take another second
without taking care of myself, and it was Nico’s fault that I was almost at my
breaking point. A dimly vague thought came to me, and with how hyped up my
brain was on my teen hormones, it became a crazily wonderful idea. I’m pretty
sure Nico wouldn’t mind, anyway.
“I promise I’ll tell you anything you want to know, Nico,” I said. I was
straining to remain coherent because I felt like there was a hazy mist in my
head that made it hard to form words. “You just have to help me, too. Just do
to me what I did for you, okay? Keep doing it until I tell you to stop.”
“Okay!” Nico eagerly nodded.
I moved so that I was sitting in front of the bed. I directed Nico to kneel
between my spread legs. He instinctively grabbed my tool with his  hands and
used all his soft, smooth fingers to wrap around it. His touch sent a jolt of
pleasure through my whole body, so much that I stiffened up and stopped
breathing for a couple of seconds. It was so intense that it was almost like
getting zapped by my friend Thalia, which was saying a lot—she was a daughter
of Zeus, after all.
It was almost funny how Nico’s small hands wrapping around my shaft made it
look a lot bigger than it really was. Even with his whole fist around it, I
could still see the head and a couple of inches poking out. His smooth hands
were kinda cold at first, but the heat of the moment made me feel like there
were a thousand tiny electric sparks every time his hand rubbed against my
sensitive skin.
I let out a hoarse grunt as Nico automatically began pumping my rod up and
down, up and down. He was clumsy at it at first, but he constantly shifted his
grip to correct himself. I was guessing that he was trying to see how to best
grip it, the way you’d try on a new sword hilt to see how it fits in your hand.
He kept stroking, my angry red tip playing hide and seek with his little fist
as he went.
“Ohhh…ohhh gods…” I moaned. I never moaned when I was doing it myself, but for
some reason, having Nico do me felt even more incredible than I’d ever
imagined. It was like his touch added this new level of pleasure I’d never
known before—every stroke was like a shot of ambrosia directly into my
bloodstream. I don’t say that lightly, because eating too much of the gods’
preferred snack practically made you explode, never mind using a syringe.
“Does it feel good, Percy?” Nico asked. I nodded at him as best I could with my
senses going haywire and my vision blurring. I gripped the sheets as Nico
increased his pace. I was vaguely aware that he was palming his own little
boner—not really stroking, but just, feeling it up in an urgent way, like he
didn’t know what to do but he knew he needed to do something to it. But it was
his face that really drove me over the edge.
Nico always looked like your typical sweet ten-year-old boy. He was often
silly, always giddy and was practically excited about everything. To see his
boyish face transfixed on my shaft was exhilarating like I couldn’t believe. I
don’t even think he noticed how his hand just sped up again, furiously pumping
away. The boy was absolutely entranced by what he was doing, as if he didn’t
really understand what was going on but wanted to do more of it anyway. It
reminded me of…well…me.
“Nico…!” I sputtered. It was supposed to be a warning, but I was too short of
breath to say a full sentence. Nico’s face was splattered with four jets of
white goo, mostly because he didn’t let go of me, and he had it pointed to his
face—probably because he was still staring at it while he was stroking.
I collapsed on the bed with my chest heaving like I’d just fought a hellhound.
I could still feel Nico’s hand on my steadily softening shaft. He was still as
a statue, with one eye closed because it had a trail of cum on it. Seeing him
so stiff like that while my spooge dripped down his face was kind of funny, in
a way.
“Oh man..that was…gods…Nico are you okay?” I managed after catching my breath.
“This isn’t pee, right?” he asked with a hint of concern.
“No, no, it’s not, I promise!” I hastily replied.
“Okay, good,” he said, his right lip curling into a small smile. He then
grabbed my discarded underwear and wiped his face with it.
“H-hey!” I protested, but Nico had already made sure that my undies were
definitely unwearable for the rest of the night.
“So…you said you were gonna teach me stuff?” He climbed onto the bed beside me
and lay down. I felt him grab my hand until my fingers straddled a warm pulsing
hardness, already slick and wet. Nico was all smiles.
I gave him a sheepish grin in return. I guess I wasn’t going to get a lot of
sleep tonight.
