****** Master's Brother ******
by BendyDick
Summary
     Master needs to go on a business trip and leaves his twin slaves
     under the care of his older brother.
Notes
See the end of the work for notes
The twins were standing at the door, matching little outfits and hair done so
it looked more tamed than usual. Both of them were pouting, they didn’t want
Master to go away and he probably should have been flattered but he was too
busy fussing over the state of his twins.
“Back straight Sebastian; wipe that pout off your faces. I want you two to look
nice. Do I have to spank you before I leave?”
The boys tried their best to be what Master wanted, even giving forced little
grins that looked more like they’d smelt something gross. It would be fine
though. The twins were cute and James would like their youth. Jim hoped his
older brother would like his pets at least.
Master nervously paced the space in front of the twins, his bags were packed
and his driver on call. There was food in the fridge this time and movies set
up in the player. He kept feeling like he was forgetting something.
“You boys will behave right?”
“Yes sir.” They answered in unison, sneaking in a lip wobble just to let him
know they didn’t want him to leave.
“You won’t cause trouble.”
“We promise sir.”
He walked forward and leaned down so he could press a kiss on each of their
lips in turn. When he pulled away from Sebastian the doorbell rang. “That’s
him. You will call him James, Sir or Daddy. Do you understand?”
“Yes sir.” Rin gave Sebastian a look and when Master turned to the door he saw
him shrug. The door opened and a man stood there with a small carry on. He was
taller than Master by almost a head. His hair was dark and he was well built.
“Jimmy, it’s been too long.” He had a voice like honey and it seemed to relax
Master’s shoulders. “How has my baby been?”
“It’s Jim now brother. Jim Moriarty, Master to the twins though. Do you like
them? I found them, my little pets.”
James stepped into the twins’ little bubble and they cowered. They weren’t shy
normally, well with Master but it had been awhile since they had seen someone
other than him. “They are young.”
“They are high energy you mean, don’t worry they enjoy themselves. This boys,”
Master started proudly as he wrapped himself around the taller man’s waist. “is
my brother, Colonel James Moriarty. I expect you to be good for him.”
Both boys nodded and grinned. “Yes sir.”
“Master…” Sebastian said weakly, watching sadly as Jim turned to grab his bag.
“I’ll… we’ll miss you…” He was so young, his big blue eyes shined under the
front hall light and his hands fiddled with the hem of his shirt. Master
swatted his hands away and pressed a kiss to his forehead then his lips.
“I’ll be back before you know it.” He pecked Sebastian’s lips again. “If they
don’t behave spankings and cold showers are the best form of punishment. I
can’t wait to catch up James.” Master pressed a kiss to his brother’s lips and
with a giggle bolted out the door.
James caught the door and closed it slowly so it wouldn’t slam. “So, introduce
yourselves please.” His voice was deeper now that Master was gone. He looked to
the two little twins and smiled so they knew he wasn’t a threat. “Shall we move
to the living room?”
“I want to watch a movie! Master left us movies.” Rin demanded, his jaw set and
back straight. James raised an eyebrow and smiled.
“Ah- you must be Severin. That makes you Sebastian.” He turned to the taller
twin who was still staring at the door as if hoping it would open and bring
back his Master. The poor dove. So little and so in love. James tapped the boys
shoulder making him jump. “You’re Sebastian, am I correct.”
“Yes sir.”
Rin whined and swayed back and forth to get attention back to him. “We want a
movie.”
“You want a movie Rin; don’t speak for your brother.”
“No… I want a movie too.”
James looked from one boy to the other taking in their hopeful little
expressions. “Fine.” They both cheered and were already half way to the living
room. “Do you want popcorn?” They both called out to him yes and he smiled.
They were cute in a puppy sort of way.
He stuck a bag of popcorn and listened to the twins murmur to each other. It
wasn’t fighting so he only half paid attention, he got bits about how they
would be in trouble, that Jim didn’t allow it. He assumed they were trying to
sneak an R-rated movie and brushed it aside. A few minutes later he was walking
out with overly buttered popcorn in a large bowl. The twins patted the part of
the couch in between them, arguing that it was better this way so they didn’t
fight over food.
“What movie did you chose?”
“Something good we promise.” Rin said, cuddling his head against James’s chest.
He looked down at the small teen strangely but didn’t try to move him. He
wasn’t sure how much cuddling he got with Jim, Jim had a tendency to be
neglectful.
Sebastian claimed the remote and turned on the tv before taking several scopes
of popcorn and piling it into his lap.
“Sebastian, didn’t Master teach you manners.”
He looked up to him scared and started to gather back up the popcorn so he
could put it in the bowl. James laughed, soft and comforting and patted the
boy’s leg. “Don’t worry, I won’t tell him.”
“I like you.” Sebastian said, bringing a piece of corn to his mouth and popping
it in then licking his little finger to get the salt off. He did that with
every piece.
James was too mesmerized by the pink lips sliding over the skinny digit to by
attention to the movie; it wasn’t until he heard the sounds of fucking that he
looked to the screen. Rin was staring at it fondly and Sebastian had a blush
spreading across his cheeks. The two of them were nude, completely nude and
probably younger than they were now. They were rutting against each other
wearing nothing but school regulation calf socks, hard ons red and leaking
against each other.
“What is this?!” James all but shrieked and reached for the controller. “Turn
this off. I don’t want to see that.”
“It’s our movie, don’t you like us?” Sebastian asked as he held the remote away
from James.
“Give me the remote or I will get the belt.” The remote was quickly handed over
and both boys pulled away from the new comer as if he had smacked them. He
hadn’t, he just didn’t want to see little kids like that. He knew his brother
had his kinks and he knew enough not to get in the way of that but the two boys
sitting on either side of him were just babies, cute but tiny and innocent.
James turned off the TV while he chose one of the actual movies his brother had
rented. They were movies he wouldn’t have chosen for teenagers, either too
babyish or too many sex scenes, but they were Jim’s kids and he could let them
watch what he wanted.
When he got back to the couch one of the newer Bonds was playing and half the
popcorn was gone. He smiled and squeezed back between the two warm bodies.
Sebastian’s eyes flew wide at the first explosion and he leaned in to get
closer, practically placing himself into James’s lap.
“Kid,” Sebastian just scooted closer with an open mouth. “S-sebatian?” The boy
turned to look and nodded. “You’re on my lap.”
“Can’t I just stay here? It’s cold.”
“Then get a blanket.”
“Master lets us watch movies on his lap.” Rin chimed in from the side, crawling
his way over as well. “We like it best like that.”
“I’m not master.”
Rin didn’t listen he just continued his way onto the older man’s lap with a
shit-eating grin. “We know. You’re new.” They were grinning at him, well, Rin
was grinning at him and Sebastian’s attention was torn between what was
happening on the screen and what his brother was doing. James felt his cock
twinge at the light weight of both boys in his lap. Sebastian was cuddled to
his chest, Rin was nudging his neck, littering soft opened mouth kisses.
“How old are you?”
Rin leaned up to whisper into James’s ear, “Twelve and three quarters. We’ll be
thirteen in a few months. ”
Babies, nothing more than little babies and Rin was practically trying to suck
his ear off. He could feel his prick hardening the same way it would if Jim had
been here instead of the twins. His brother had trained them well.
“Boys, I am warning you.” James said in the most authoritarian voice he could
muster though it didn’t sound all that threatening when his voice cracked in
the middle. “If you don’t get off my lap and settle down there will be
consequences.”
“So that’s where Master gets the words he says.” Rin all but moaned into the
elder’s ear.
“His vocabulary you mean?”
“Yeah, that thing. Let me help you.” The boy’s hand slipped under his brother’s
bottom and gave James’s cock a little squeeze. “I can make your mind go blank,
Master showed me how. I am the best.”
James didn’t doubt that but everything in his body was screaming for him to say
no. Sure Jim and he had started young, he wasn’t much older than the two kids
on his lap and Jim was just a tiny tike, it had been okay back then but Jim was
a slut. Jim was always ‘up for it’. Then again Severin was practically trying
to jerk him off through his trousers.
“Move Sebastian or help me.”
“Sorry… but can’t we wait till-”
“We always do what you want. Master always does what you want!”
James’s head slowly came back into reality as Rin pulled his hand away to shove
at his brother. “Boys, calm down. What is it you want Severin?”
“I want to be the best. I want to show you I am better than my brother.”
Severin was all doe-eyes and pouting lip. His blond hair and round cheeks only
added to his cuteness and James could feel himself melting. Sebastian looked
sad but Severin, Severin looked ready.
“Are you sure that’s what you want?” Rin’s eyes were glued to James’s crotch
and he nodded happily. “Fine then, call me Daddy.”
“Yes Daddy.” Rin grinned and shoved again at his brother. “Sebastian is being a
party pooper.”
“I just want to watch the movie first…”
“And that’s okay love.” James whispered softly into Sebastian’s ear as he
pushed him off his lap letting him curl up with one of the couch cushions. It
was easy to tell Sebastian was Jim’s baby. He still looked so sad and James
only wished he could help the boy take his mind off it. Jim would be back. “You
can watch the movie and I will play with Rin-rin.” Severin’s face lit up with a
huge grin. “You like your nickname?” He nodded and crawled into the space his
brother had left.
“Master doesn’t call me Rin-rin.”
“What’s he call you?”
Severin looked down to the floor and gave a sneaky little smirk.
“Troublemaker.” It was easy to see why. He looked up a second later with big
blue eyes and a the same devious smirk. He wanted something. He was just like
Jim. Selfish and cunning little pricks.
“What do you want babes?”
“I told you.” He leaned in to peck James’s lips and he grinded his hips across
the other’s still hard member. “I want to be your favorite.”
Severin was all sorts of messed up, it didn’t take an expert to see that. He
screamed daddy issues and Stockholm syndrome but James wasn’t in a place to
help him out of the hole the boy had been shoved into. Life sucked all over.
Jim was nice enough to him even if he seemed to have starved to boy of
affection so James just sat back and reaped the benefits of years of training.
The kid’s hands slid James’s shirt off with practiced skill. His mouth kissed
across the muscled chest and at his nipples stopping only to mumble about how
different than Jim it was. For a second James wondered if the twins were
allowed outside the house. Sebastian, for as loyal as he was being, kept
looking over at James, studying him, sizing him up as if he were a toy. Hell he
was a toy to these little boys and that much of obvious when Severin started
nipping him random places to get him to yelp.
“Stop that kid.”
“You make funny noises.” The boy smiled and nipped at James’s jaw. “And you
don’t yell at me for it.”
“Now I see why you are a trouble maker.” Severin blushed. “No, no Rin-rin. It’s
okay. Daddy loves you. Daddy loves you a lot. Keep doing what you’re doing.
Maybe Sebastian wants to join?” It was just an offer. Sebastian had stopped
paying attention to the movie almost completely by now. The older one shook his
head, cradled the pillow to his chest and turned around. Loyal little puppy.
Severin went back to his experiments. He licked, kissed, bit and poked James’s
body until he was content and James was hard. Rock hard. Severin liked that. He
grinned as he rubbed the bludge through James’s trousers. “You can fuck me. You
can fuck me until I scream and beg you to fuck me harder. I don’t care if you
make me bleed.”
“I would never make you bleed.”
“You are big though.” Severin grinned and slid easily off the couch to kneel
between his legs. “It might tear my small body right open.” He pressed a slutty
kiss to the little wet spot were the precum was darkening the fabric. “I don’t
even know if I can fit all of you in my mouth. Should we see?”
Slut.
“Yes baby; let me see what my big boy can do.” Severin’s face couldn’t possibly
be any brighter as he hurriedly undid James’s trousers, pulled down his pants
and let the cock he’d just been admiring pop out impressively. He was right; it
did look massive compared to his small face. The boy’s eyes were wide as were
his brother’s who was still pretending like he wasn’t looking. James would let
him pretend. No use scaring the small boy.
“Do you like it like this?” Severin dipped his head and allowed his lips to
travel softly, teasingly up James’s dick till he reached the tip and popped the
head into his mouth for a little suckle. He was good at that. He pulled off and
licked his lips before speaking again. “Or like this?” Without a seconds
hesitation the boy slammed the whole massive dick into the back of his throat
and started to hallow his cheeks around it. James gave a moan and grabbed a
fist full of Severin’s dirty blond hair. He pulled off with a pop a moment
later.
“Second definitely.”
He didn’t wait for more instruction and damn it he didn’t need them. He was all
force from then on. Shoving the cock down his throat until James could feel him
gagging around it but Severin gave no indication that it bothered him. He’d
pull off to play with his tongue over the tip giving no doubt the second
sluttiest face the world has ever known. Jim’s came first.
Severin had his button nose nuzzled against James’s dark hairs when he gave a
little moan alarming James. It wasn’t a ‘I’m such a good slut I get off on the
taste of you’ though the boy had been making a lot of those this was a true
moan coming deep from the back of his throat and when James looked down he
understood why.
At some point in the midst of James and Severin’s little love fest Sebastian
must have gotten jealous because he was tucked up under his brother’s bare legs
sucking on his brother’s dick. James tried to pull away to watch them but
Severin wouldn’t let his cock get more than a few inches away from his lips.
They were cute; Severin’s mouth pulled into a wide O above Sebastian’s almost
identical little pink lips stretched almost as wide, but not quiet. They were
good little boys, Jim had trained them well.
Severin reclaimed James’s cock after a second and started to milk his orgasm
from him. He sucked, licked and bobbed his head better than men twice his age
and with each little tongue flick James gave a moan and with each moan
Sebastian got from his brother the closer James got to tipping off the edge of
his pleasure cliff. His finger’s tore at the fabric of the couch as he tried to
keep his hips from rutting into the boy’s mouth, while he was sure he could
take it it was more fun to see the kid bob up and down. It didn’t take much, a
flick over the tip of his shaft and a good throating moan, for him to be coming
deep within Severin’s throat. The boy didn’t even flinch just swallowed around
the man’s softening prick and came off with a small pop.
James finally managed to scoot away far enough to watch the two twins go at it.
It looked eerily like his own babies, Richard and Jim, when they had been that
age. All desperate rutting sweaty bodies against one another in attempts to
fight off bad dreams but these boys were blond and bigger than the twins had
ever been.
Severin was drenched in sweat after a bit and despite his brother’s tireless
efforts he wasn’t getting any closer to his release. He kept glancing up at
James in panic stricken horror as if begging for something. Eventually
Sebastian started giving the same glances though his mouth didn’t stop sucking
and bopping.
“Oh-oh right.” James thought suddenly and started to feel bad for the no doubt
tired little boys before him. “You can-can come Sev.” Instantly the boys head
flopped down on the couches cushions and he gave a startled cry as he spasmed
into his brother’s mouth. Sebastian slid out from under his legs and licked
away the cum that spilled from his lips, bringing a finger up to make sure he
got all of it.
“Thank you.” Severin mumbled into the pillows. “Thank you Daddy. Did I do good
Daddy?”
“You did amazing. Such a good little baby.” Severin turned to beam up at him.
Sebastian sat on his knees looking down at the carpet. “You to Bastian. You did
good too.”
“Not amazing.” Severin chimed from the couch as he finally pulled himself
together and stood on wobbly limbs to come kiss James’s chest. “I did amazing.”
“Good boys don’t brag.” He shut up immediately. “Come here Sebastian. You can
show me what a good boy you are later okay? I know you are a good boy. You boys
ready for bed?” Severin was about to complain but an eye brow raise from Daddy
was all it took for that sassy little mouth of his to clam right back up. “Come
along Sebastian.”
He flicked to TV off before coming to stand next to his brother. They were so
different the two of them. James knew well enough that just because two people
were twins didn’t mean they acted the same but sometimes it still shocked him.
Severin was grinning at him, Sebastian was staring at his toes as he flexed the
and unflexed the over and over. It was hard to believe Jim didn’t like Severin,
they were almost the same mischievous wise.
James pulled the boys into a tight hug and kissed the tops of their heads. “You
are good boys.” They nuzzled closer to him, wrapping their own spaghetti arms
around his waist. “Such good boys.”
