****** Little Bro ******
by Madriddler
Summary
     Cedric finds Harry in the prefect's bathroom worried about his own
     development and decides to teach his new "little brother" some very
     important lessons.
                                  Little Bro
                            (a gift to devbro1996)
Harry found himself at the Prefect’s bathroom for the fifth time. Ever since
Diggory told him about it, and Harry saw the bathroom itself, the boy couldn’t
help but use it whenever he could. It was mid-December now. Outside snow was
falling at a rapid place, and Harry couldn’t help but wonder how the Bulgarian
boys could handle this weather. Especially Viktor Krum. Harry would be lying if
he ever said that he didn’t spy or sneak looks at Krum every now and again. It
was hard not to. Krum just was an embodiment of masculinity to Harry, and the
complete opposite of him. Krum was tall where Harry was short. He was muscular
where Harry was lithe. He was big where Harry was small.
Cedric was the same way.
Harry couldn’t help but stare at both boys. They seem so different from Harry
that it surprises Harry every time he had to remind himself that they were the
same sex. Harry took off his clothes and stared down at his body. Though he was
fourteen, puberty barely started on him. He was still hairless, his body smooth
to the touch and soft. His pink nipples erect in the cold air. He had no muscle
definition, instead his smooth body was flat from his chest, down his stomach
to his small dick that laid flaccid on his balls. Harry had a small perky butt,
however that was the only part of his body that had any definition. Harry
sighed and looked down at his dick and balls and held them with one hand,
looking sorely disappointed. Why aren’t you big?He thought to himself. Everyone
else’s was. He knew because he kept stealing glances at his dormmates as they
change.
Ron’s was long like him; Dean’s was thick; Neville’s looked like a third arm
and Seamus’s cock looked as if it could break anything if it tried entering.
But Harry’s… Harry’s stayed small… barely reaching five inches when it did get
hard, which was always around other guys.
Harry personally didn’t know what it meant. He knew that he was different from
everyone else, Dudley and his gang beat that knowledge into him every summer,
but Harry was supposed to be looking at girls now, noticing girls and their
parts but instead he was too focused on Ron’s cock, or Neville’s cock or
Seamus’s monster that hung between his legs than any of the girls he knew.
Harry flicked his little cock and sighed. “What is wrong with you?” he groaned.
“Nothing’s wrong with me Harry, why is something the matter?” Harry jumped at
the voice and turned in shock to see Cedric Diggory walking confidently towards
him. “Taking a liking to the baths I see, not that I blame you, it is very
good.” He gave Harry a small smirk and took off his robe. “Hope you don’t mind
I join you.”
“No I….” Harry flushed as Cedric stripped in front of him. Cedric was big. His
broad shoulders, muscular chest and abs that had some hair on them… perfect
legs and, between them, Harry’s mouth suddenly went dry.
Huge was not enough to describe it. There was a monster between Cedric’s legs.
It looked to be the width of Harry’s arm and very long with two huge balls
hanging underneath it. Harry couldn’t stop staring. As Cedric bend down to turn
the facets on Harry got a clear view of the cock and balls that put his small
dick to shame. Six inches and it didn’t even look a bit hard. Cedric stood up
and turned around to Harry’s staring. “See something you like Harry?” he joked.
Harry nodded slowly. With a shaking hand he pointed towards Cedric’s cock.
“Big…” he said stupidly.
“Yeah, I’m a bit big… biggest in my year at least,” Cedric admitted. “But don’t
worry, I’m sure you’ll grow.” He winked and the next second he was next to
Harry. “Are you worried?”
“About the Yule Ball—”
“No, about this,” Cedric said, and he flicked Harry’s cock. A spark shot up
Harry’s spine that made his brain feel gooey.
Harry bit his lip and looked up at Cedric. “I’m smaller than everyone else,” he
admitted. “I’m worried that…”
“That you won’t grow?”
Harry nodded. “And that I’m a freak. I know that I’m already am… I don’t look
at girls the way that I look at boys…”
Cedric laughed and Harry stared at him. He didn’t say anything funny. “Harry!
You’re not a freak,” Cedric smiled. “You’re just a small gay boy. In our
community, we call you a twink.”
“A twink… what do you mean our community?” Harry asked, confused.
Cedric smiled. “I’m gay too Harry,” he said.
“But Cho—”
“Is my friend, but nothing more,” Cedric said.
“But I heard that you two were going to the ball together,” Harry said.
“Lies, I would rather take a cute twink with me,” Cedric smirked. Harry blushed
and looked down at his body.
“You think I’m cute?”
“Yes.”
“That… that’s the first time anyone called me that,” Harry said.
“Really? No! You must have been called cute all the time growing up,” Cedric
said.
Harry shook his head. “No… I… I um didn’t exactly have a good childhood. My
cousin beat me and my aunt and uncle neglected me… would you believe that I
haven’t been hugged? Ever?”
Cedric stared at Harry and immediately wrapped his arms around Harry, pulling
the boy into a deep hug. Harry’s breath hitched as he felt both his and
Cedric’s cocks growing. Harry blushed and tried to move away. Cedric didn’t
allow him to. “Cedric—our dicks—”
“Are getting hard, yeah,” Cedric chuckled.
“You’re not embarrassed?”
“Please Harry, our dorm has a masturbation circle,” Cedric chuckled. “It’s
natural.”
“Mastur…bation?” Harry asked, looking up at Cedric with the pure innocence of a
child.
Cedric stared down at Harry. “You never heard of that before?” he said,
shocked. Harry shook his head, his cheeks blazing red. Cedric smiled and placed
a big hand under Harry’s chin, lifting it up gently to force Harry to look at
him. “Harry, baby, looks like you have a lot to learn,” he chuckled. “You never
heard of masturbation? That’s horrible.”
“I had no time… is that bad?” Harry asked.
“No, but don’t worry, your big brother Cedric here, will teach you now,” Cedric
smiled.
“Big brother?” Harry repeated, liking the sound of it.
“Yeah, Cedric nodded. “Now every good masturbation session starts with a kiss.
Have you been kissed before, Harry?”
“No,” Harry shook his head. Cedric smiled and pulled Harry up as he bent
slightly, taking the Golden Boy’s lips into his own. Harry gasped but found his
eyes slipping close as Cedric’s hand wrapped around his body, his other hand
holding onto Harry’s face. Harry felt a low purring moan escape his throat and
his mouth opened slightly. Cedric opened his own mouth with Harry and thrust
his tongue out towards Harry. Harry answered with his own tongue and moaned as
Cedric’s hand wrapped around him moved down towards his small ass, cupping one
of the butt cheeks, his fingers grazing against Harry’s hole. Harry’s breath
hitched and he opened his eyes quickly.
Cedric smirked as he moved away slightly, keeping his fingers directly on top
of Harry’s hole. “This,” he said, pushing against the hole, “will make you feel
very good, little brother.”
“My… my butt?”
“Yeah but that’ll come later,” Cedric smirked. “For now… we’ll start your first
lesson little bro. Get in the tub.”
Harry nodded and stepped towards the tub, slipping into the hot water that
warmed him instantly. Cedric moved to sit at the edge, his legs spread to the
side and his cock and balls hanging off the edge. Harry couldn’t help but lick
his lips as he stared at the cock. “You like my cock, don’t you Harry?” Cedric
chuckled. Harry nodded. “Good. A little brother should love his big bro’s cock.
Now make me hard. Just grab my cock with your hands and moved them up and
down.”
Harry touched Cedric’s cock and felt a heavy, hot weight between his fingers.
He wrapped one hand as much around Cedric’s cock as he could and slowly moved
it up towards the fat mushroom head. As he did so, Harry stared at the pubic
hair growing around Cedric’s cock and balls, wishing and wondering when he
would grow his. He looked up at Cedric to see the older boy shiver as Harry
slowly moved his hand up and down the monster cock.
“Good job little brother,” Cedric moaned, his hands tangling themselves in
Harry’s hair. “Now play with my balls with your other hand.”
Harry reached and gently grabbed Cedric’s balls. They were heavy, very heavier
than Harry was expecting, and warm. Harry liked the feel of them as his moved
his fingers around the two balls. He guessed that he was doing a good job as
Cedric moaned. “Good job Harry… you’re a natural at this.”
Harry smiled at the praise and continued his work. “You’re so big, big
brother,” he said looking up at Cedric, who chuckled.
“Your big bro’s a strong man, little bro, of course I’m big,” he chuckled. “But
don’t worry, you’ll be big too if you stick with me.”
Harry smiled at that. He leaned in close to Cedric’s cock and took in a deep,
long breath, inhaling the musky teen stench of Cedric’s cock and balls. The
small boy moaned and felt his dick getting hard. He looked up at Cedric, “My
cock is getting hard, big brother,” he mewled.
“You don’t have a cock Harry,” Cedric chuckled. “That small thing between your
legs? It’s not a cock yet, you don’t get to call it that.”
“Then what do I call it?” Harry asked, giving Cedric’s cock a slow tug.
“A dicklet,” Cedric said. “You have a small dicklet while I have the cock.”
Harry nodded. “My dicklet’s getting hard, big brother,” he said.
“Don’t touch it Harry, focus on my cock,” Cedric ordered.
“Yes big brother,” Harry said. He began to get in a comfortable rhythm as
Cedric played with his long black hair.
“One day, you will get a haircut to have your hair look just like mine Harry,”
Cedric mused. “That way, you can be more like your big bro. Do you want that?”
Harry nodded enthusiastically and looked at Cedric’s humongous hard cock that
was nearly a foot long now. White stuff was started to ooze out of the cock
head. Harry pointed this out. “That’s pre-cum,” Cedric said. “Lick it all up
Harry, it’s really good and good for you.”
Harry leaned forward again and stuck his tongue out. Hesitantly, he touched his
tongue to the hot meat of Cedric’s cock and curled his tongue upwards, scooping
up some of the pre-cum. It was musky like Cedric yet highly addicting. Harry
gave Cedric’s cock another lick, then another and another, all of which caused
his big brother to moan and Harry to smile as he realized something.
He loved the taste of cum.
Harry began lapping up Cedric’s pre-cum, and when the head was clean, the cum-
addicted teen pushed the tip of his tongue into Cedric’s piss-slit for even
more cum. “Harry,” Cedric moaned. He pushed Harry’s head down and the boy ended
up swallowing the fat head of Cedric’s cock. Harry’s eyes went wide and he
started to choke. Cedric pulled Harry’s mouth off of his cock and up towards
him. “Breath through your nose Harry,” Cedric said. “You’re going to learn how
to give a blowjob, alright? I’m going to fuck your mouth. Remember the pre-cum?
Do this right and you’ll be able to drink up all of your big bro’s cum and
become strong like him.”
“I want to be strong like my big bro,” Harry gasped.
“Good boy, then keep your mouth wide and breath through your nose,” Cedric
ordered. Harry nodded and opened his mouth as widely as he could. Cedric angled
his cock towards Harry’s head with one hand and used the other to slowly push
Harry down on it. Harry’s jaw began to ache, his mouth never felt so full in
his life, but he wanted the cum, he wanted to be strong like his big brother,
he needed to make his big brother happy.
Cedric smirked as he pushed his cock deeper and deeper into Harry’s mouth; the
boy was a quick learner and did not gag as the cock pressed against the back of
his throat. My boy has no gag reflex. Good Harry,Cedric smirked. “I’m going to
keep my hand on your head Harry, but you need to move up and down my cock with
your mouth just as you did with your hands,” Cedric ordered.
Harry nodded the best he could around Cedric’s cock. He began to move away from
the pubes, their musky, addictive smell becoming weaker as he moved, his tongue
dragging along the underside of the cock. Cedric moaned and leaned back as he
let his little bro go to work on his cock. Harry started with a slow, calm pace
as his mouth got used to Cedric’s wide cock. Cedric winced when he felt Harry’s
teeth scrape along his cock and slapped Harry’s face lightly. “Make sure your
teeth don’t touch my cock, Harry.”
Harry just moaned around the cock, obviously taking equal if not more pleasure
than Cedric as he moved up and down the cock, his lips dragging cutely along
the hot meat. Such a pretty boy, I’m a lucky big brother,Cedric thought to
himself as he began envisioning the changes he would make to Harry.
The glasses would have to go. Though they were adorable, Cedric would not allow
his little bro to have glasses. Muggles have an alternative and he’ll make
Harry wear those instead. Next the hair, like he said Harry’s hair will become
exactly like Cedric’s, maybe he’ll even dye it to look more like his.
“Good boy, start going a little faster… ahhh yeah, that’s it Harry,” Cedric
moaned. He could feel his balls starting to tighten up. His grip on Harry’s
hair tightened and he began thrusting into Harry’s mouth, causing his little
bro to gag on his cock as Cedric did his best to bury his cock deep within
Harry’s hot, tight throat. “Fuck I’m close little bro,” Cedric groan. “Going to
cum deep inside your throat, Harry. Fuck! You’re gonna drink it all.”
Harry moaned, his eyes closed and tongue wide as he craved for his big bro’s
cum. Harry stayed still as Cedric used his mouth, his balls tightening more and
more, the heat boiling in until finally, with a loud scream, Cedric came hard
inside Harry’s mouth. The little boy began swallowing immediately, his mind
high on lust as all he thought about was swallowing his big bro’s cum,
absorbing his essence and becoming more like Cedric.
Hot cum filled his mouth quickly and it began leaking down Cedric’s hard shaft.
Harry moved his hands quickly, cupping around the base of Cedric’s cock to save
the cum from dripping into the bath below. A small puddle formed in his hands
as he continued to swallow until at last he couldn’t feel Cedric’s cock
throbbing inside his mouth, but it stayed just as hard as Cedric pulled out,
Harry licking and cleaning it for any traces of cum he missed.
“You love my cum, don’t you Harry?” Cedric chuckled as Harry went to eating up
the small puddle of cum in his hands. Harry looked up, his lips and chin
stained with the white cum and he smiled, nodding. Cedric chuckled and moved
back. “Eat all of it, little brother, than get out of the bath,” he ordered.
Harry went back to eating the cum, his tongue dragging and scooping up the
sticky hot mess that he loved so much. When he was fully clean, Harry pushed
himself out of the bath, his small dicklet hard and leaking.
“Look at that Harry, you’re making your own cum,” Cedric laughed. He flicked
Harry’s small dick and winked. “Remember, no touching little bro.”
Harry nodded.
“Remember how I touched your ass and told you that it’ll make you feel so
good?” Cedric asked.
“Yes, big brother,” Harry said.
“Good boy, now get on your hands and knees Harry and stick up that cute butt so
your big brother can see your hole,” Cedric said.
Harry bent down and rested on his arms as he stuck his ass as high in the air
as he could while being on his knees. Cedric knelt behind him and grabbed both
of Harry’s small ass cheeks. “So pretty little bro,” Cedric chuckled, giving
each cheek a quick swat. “You look so beautiful Harry, so pale and pink… I bet
you never touched here,” he chuckled. “Ahh… but clean, very clean. Good little
brother.”
Harry gasped as he felt Cedric spit at his hole before dragging his tongue wide
along it. Cedric buried his face in Harry’s ass, his mouth open as he expertly
licked and prodded Harry’s hole with his tongue, loosening it very gradually.
Harry moaned highly and pushed his ass against Cedric’s tongue, something deep
inside him craving for more. “More, more,” he mewled.
“You want more?” Cedric smirked.
“Mmm-hmm,” Harry said. Cedric smirked and reached for his wand. “Do you want to
know what I’m going to do to you, Harry?”
“What are you going to do to me, big brother?” Harry asked, both extremely
turned on and slightly scared.
“I’m going to stretch and lube up your hole before forcing my big fat cock
inside,” Cedric cursed. “Then I’m going to fuck you until all you scream, all
you know and want is your big brother. And lastly, I’m going to cum inside you
so that tonight you’ll have a constant reminder of who you belong to.
Understand, little bro?”
“Yes, big brother,” Harry moaned.
Cedric found his wand and without any warning, shoved it inside Harry’s tight
ass. Harry wiggled in discomfort but all of that faded away as Cedric whispered
something and suddenly he felt his hole open wide and became very slick. Cedric
smirked and dropped his wand, aligning his cock with Harry’s magically
stretched hole then shoved the whole thick monstrous cock in until his balls
slapped against Harry’s butt.
Harry gave a half scream half moan as Cedric entered him. He felt as if his
brain was on fire and all he could think of was his big bro’s cock. Cedric did
not wait for Harry to adjust as he began fucking at a ferocious pace. He bent
over Harry, his muscular chest and torso pushing against Harry’s slender back
as one hand grip Harry’s throat and the other one steady them both.
“You’re mine, Potter, mine,” Cedric growled out. “You belong to me now. Your
ass, your dicklet, your head, your body—everything is mine.”
“Yours big brother, yours,” Harry cried out, the wet sound of skin slapping
against skin filling the room. Tears strained his eyes as he felt Cedric’s cock
ramming inside him, messing up his innards. He looked down and cried out when
he saw a small bulge appearing now and again at his lower stomach. “Fuck,”
Harry cursed.
“That’s it Harry, good,” Cedric growled. “Be the slut you are for your big
bro.”
“I’m a slut…”
“That you are, my slut,” Cedric panted. “Love you so much, wanted you since
last year.” His hips piston against Harry’s ass, his balls slapping
aggressively as his cock seemingly went deeper and deeper inside Harry’s tight,
hot hole.
“Yours, big brother, always yours!” Harry cried out. He could feel his balls
bunching up towards his body and his dicklet felt weird as if he was going to
pee. “Gonna pee—feel weird—”
“Let it out, Harry,” Cedric growled. “Cum for your big bro. Scream my name.”
“CEDRIC!” Harry screamed and his dicklet pulsed as thick cum jetted out and
stained the floor. Cedric didn’t last long as Harry’s ass tightened around his
cock, squeezing and juicing it for him to cum. Cedric bit down on Harry’s neck
and screamed, sending vibrations down the boy as he came. Harry felt his
stomach being flooded with a hotness.
Panting heavily, Cedric pulled out of Harry and took a moment to admire his
work. Harry’s hole was open, he could see his cum already leaking outside.
Cedric scooped it with his finger and shoved it back in before casting a charm
on Harry’s hole which locked his cum inside. “Harry,” he breathed, and pulled
the boy onto his chest. Harry nestled in and the two kissed lazily. “I wasn’t
lying,” Cedric said. “I do love you.”
Harry looked up from Cedric’s chest and smiled. “I think I love you too, big
brother Cedric.”
Cedric smiled and rubbed his nose against Harry’s. “Good boy… now why don’t we
get clean now?”
 
Harry shuffled nervously as he stared at his reflection in the mirror. He
changed a little in the two weeks that separated his and his big brother’s
first fucking and the Yule Ball. First, he got a new haircut. Now he looked
just like his big bro, which he prided himself so much. Second, he was dressed
in a dress robe that Cedric picked out for him that matched the one that Cedric
promised that he was going to wear. Third, he was starting to like the color
yellow a lot more. And lastly, but most importantly to Harry, not a day goes by
without him sucking or getting fucked by his big brother’s cock. He knew that
he was in love with it at first sight. There were times when he just craved his
big brother’s touch and pulled Cedric away from his friends just for a cuddle
or more as Harry’s hands always found his way to Cedric’s cock.
Harry was practically grinning as moved to the side of the entrance hall with
the rest of the Triwizard Champions. He and Cedric looked practically
identical, except for Harry’s glasses which Cedric promised would be soon to
go. Cedric promised to take care of Harry like a big bro is supposed to do, and
Harry loved it. As they waited for the doors to open to the Yule Ball, Harry
leaned up and kissed Cedric deeply. “I love you, big brother,” he whispered.
Cedric chuckled ruffled Harry’s short hair and kissed his nose. “Love you too
little bro,” he said. “Don’t worry, I’ll take care of you from now on. You’re
my responsibility.”
“I’d love that Cedric,” Harry said.
“Then just follow my orders like the good boy you are, and I promise to make
you the happiest boy in the world,” Cedric declared. Harry smiled and kissed
Cedric again, wrapping his arms around him. “I love you Harry Potter,” Cedric
whispered.
“I love you, big brother Cedric.”
