Summary
     14 year old Mokuba has become withdrawn and avoidant of his brother.
     When Seto cathes him crying one night he is determined to find out
     what is going on.
Seto turned his laptop off, which he couldn’t concentrate on for the
last hour anyway. There was something bothering the young CEO. Mokuba had acted
very strangely that evening. When he had told his little brother that he had a
weekend off, for the first time in months, the teen was thrilled, but when he
came home, Mokuba was really quiet and asked if he could be excused right after
finishing his dinner.
 
Seto stretched and yawned. Deciding to catch some rest, he got up and started
to ascend the stairs to the second floor. His mind wandered back to his
brother. Since the boy turned 14, Mokuba was changing rapidly, physically
– he’d grown a lot: he was now barely a head shorter than his
older brother – but mostly in his behavior. From a bouncy, happy,
confident kid he had turned into a serious, withdrawn teenager. Seto missed his
smile and the way he would leap at him when he came back after  a hard
day. His cheerful voice always managed to lighten the CEO’s mood.
 
He kept telling himself that it was normal; Mokuba was growing up and being a
Kaiba on top of being a teenager was not easy after all. But a part of him
worried about his little brother, the part that always wanted to protect him
from the cruel outside world. The world that was out to hurt them given the
chance. The world that no one had protected him against.
 
Seto walked into the corridor, with the intention to go right to his room, but
stopped when he heard a sound from the door on his left. He came closer,
wondering whether he had heard it wrong and then there it was again; soft sobs
coming from Mokuba’s room. There was one thing Seto could not bear and
that was to hear his little brother cry. He grasped the doorknob and pushed the
door open soundlessly. What he saw there was heartbreaking: Mokuba was lying on
his bed, raven hair a mess and his shoulders shaking with sobs. Those were the
kind of tears that could not be taken away by a hug or a bandage and for a
moment Seto felt totally helpless. It reminded him of the time their parents
had died. He had been unable to do anything to console his brother then either.
 
In an instant he closed the distance between the door and the bed and sat down.
Mokuba, who was suddenly aware of his brother’s presence, froze. The
older Kaiba laid a hand on his brother’s back, making slow, soothing
circles.
 
“What’s wrong Moku-chan?” he asked softly.
 
Mokuba wiped away his tears, but didn’t look at Seto.
 
“It’s nothing.”
 
“Please don’t lie to me. I can see you are very upset and I want
to help you.” He tried to turn his brother to face him, but failed.
 
“You can’t help me,” responded the teen barely audible.
 
The CEO frowned.
 
“I know I haven’t been around much lately and I’m sorry,
but I really tried to care for you the best I can. Please don’t tell me
we’ve grown so much apart that you can’t trust me anymore. Do you
think me as heartless as everyone else seems to?”
 
At that the raven haired boy did turn, looking shocked. He looked really bad,
his brother noticed: skin pale, bags under his eyes. He looked like he had not
slept for weeks. Seto wondered how he could have missed the change. This,
whatever it was, must have been going on for some time
 
“No! It’s not you fault. I trust you. It’s me. I’m
the one who should be sorry, because I’m the one that’s been
avoiding you.”
 
“But why?” The older Kaiba was really confused now.
 
“I…I can’t tell you. You’ll hate me for it.”
He ducked his head, blushing.
 
Seto caught his chin between his fingers and turned his head so that he was
looking his brother in the eye.
 
“I could never hate you, little one. I love you more than life itself.
And it’s breaking my heart to see you hurt.” Then he leaned in
and planted a soft kiss on his brother’s forehead. That did not have the
desired effect. Instead of calming down, Mokuba started to cry louder and
buried his face in his brother’s chest. Seto wrapped his arms around the
sobbing boy, pulling him close. The teen started to push against him, trying to
get away, but his brother would have none of it.
 
“Please…don’t touch me…I
can’t…” Then he just gave up.
 
“It’s no use. I’m so tired of faking and denying. It hurts
so much.” His hands slipped around the CEO’s neck and he looked
up into the icy blue eyes full of concern.
 
“You wanted to know what’s wrong with me? Alright, I’ll
show you.” Saying that he slammed his lips against his brother’s
in a bruising kiss. It was like the young boy poured all his raw emotion into
the kiss, it was far from sophisticated, more teeth than finesse, but it
definitely got the message across. Seto’s eyes widened with shock, but
he didn’t push him away. The kiss ended just as suddenly as it began.
Mokuba was gone from his brother’s arms and rolled up in a ball on the
other side of the bed, crying.
 
“Mokuba…”
 
“Are you disgusted by me Seto?”
 
The CEO sighed. Then kicked off his shoes and climbed onto the bed, wrapping
his arms around his brother and burying his face in his dark locks.
 
“Like I said: I love you. I will never be disgusted by you. I think the
right word is surprised. Would you care to tell me what’s going
on?”
The boy in his arms relaxed a little and a shiver run through his body.
 
“I don’t even know what I feel anymore. One thing that I do know
is that I love you niisama. More than anything in the world. When I was little
you were the only important person in my life. You still are. I always thought
that as long as we’d be together everything would be ok. I even thought
one time that it was a shame that I wasn’ot born a girl, because then
you could have married me and we’d be together all our lives. Silly
isn’t it?”
Seto chuckled softly in Mokuba’s hair.
 
“But things started to get more complicated after I turned 14. I was
thinking more about things, about us and stuff. I started to understand that my
love for you was too strong to be normal and I started to develop…other
feelings for you.” The teen sighed deep before he continued.
“First rather innocent things like wanting to hug you longer, maybe kiss
you, but those feelings got more intense and I just couldn’t,…
can’t suppress them.” Mokuba choked away a sob. Seto rubbed his
hand over his brothers back, soothing him.
 
“It’s ok, you can tell me. What feelings exactly?”
 
“I started to fantasize about you. You know, being with you…in a
sexual way.”
 
The older Kaiba slowly turned his brother towards him, but the teen
didn’t look at him.
“Listen, I understand how you feel. I had the same feelings when I was
your age.”
 
Mokuba looked up, surprised. ”Really?”
“Yes. It’s normal for  a teenager to discover new feelings.
But you were very little and I thought, and still consider, it my duty to
protect you. Even from myself. So I managed to lock them up inside me and to
take some distance from you.”
 
“Was it when you told me I could no longer sleep in your bed when I had
bad dreams?”
 
Seto blushed. “Yes. I can’t believe you still remember. But I
know now how it feels to be avoided and I’m sorry that I’ve put
you through that.”
 
“Same here, I guess.” Mokuba paused. Then added hesitantly:
“So…now what?”
 
“I don’t know. I think you should first find out what your
feelings really mean. Most teens go through similar thing, maybe it’s
only a phase. I don’t want you to do something you’ll regret
later and…”
 
But his brother cut him off: “I know what I want. I want you.” He
looked up at Seto with his defiance that disappeared as quickly as it came and
then, suddenly embarrassed, buried his face in his brother’s t-shirt.
“I want you so bad it hurts.”
 
The young CEO patted his head lovingly and gave him a firm hug.
“Mokuba, can you tell me what made you so upset today? You seemed very
glad when I told you I took a week-end off.”
 
“I was,” came the muffled reply. “I really thought I was
finally able to control my feelings and was looking forward to some quality
time with my big brother, like in the old days, but then you came home wearing
THAT.”
 
The older Kaiba was confused again.
“What do you mean?”
 
“Well look at yourself! Do you have any idea what those clothes do to my
teenage hormones?”
 
For a long time Seto had to wear suits to work, because he had a lot of
important meetings, but none today. So he decided to wear something lighter,
because of the weather, comfortable and something that suited him better: a
tight, black turtleneck and a black pair of tight fitting jeans. Oh. Now he was
starting to understand Mokuba’s reaction. Did his brother think he
looked hot? He had to admit, the thought was titillating, but he did not yet
dare to do anything about such feelings.
 
He carefully placed his hands on both sides of Mokuba’s face and looked
him in the eye.
“Mokuba, you know I love you. I want to give you everything I have and
teach you everything I know, but I don’t know what you really need. I
don’t want to rush things.”
 
“I need whatever you are willing to give. But…” Mokuba
trailed off, “is it also what you want, or are you only sacrificing
yourself for me, like you’ve done all your life? I don’t want you
to do that. I don’t want you to think that you owe me something.”
 
Seto’s eyes grew wide and his hold on his brother’s face turned
slightly uncomfortable. “How can you say that? I love you with all my
heart. I’m not sacrificing a thing! Do you have any idea how beautiful
you are?”
 
“R…really? You think I’m beautiful?”
 
“Yes. You are and always have been the most beautiful person I ever
knew. And you only keep improving when you grow.”
 
It was true, Mokuba was growing into a very good-looking young man. His raven
hair was still very long, shiny and soft like silk. All his baby fat was gone,
making room for muscles he got from all the sports he attends and he was
growing tall, not yet as tall as his brother, but pretty tall for his age. And
then his eyes. Seto loved the way his brother looked at him. It made him feel
special and loved. And he was. Mokuba really loved him in every imaginable way,
and he wanted so bad to make his little brother happy. He wanted them both to
be happy. It had always been his goal: to try to make up for all the pain and
horror in their past by giving Mokuba the world.
 
He leaned in and placed light kisses on the soft cheeks, kissing all the tears
away. Then he moved on to his lips, very gently deepening the kiss. Feeling a
hot, little tongue slide into his mouth, he pulled his brother closer. Mokuba
couldn’t stop a moan from escaping his lips. He had dreamed about this
for so long and now it was really happening. The smaller boy joined in the kiss
with such fervor that Seto was for a moment taken aback. He then regained his
composure again and carefully broke the kiss.
 
“Mokuba, slow down a bit. I know you’re eager, but if
we’re going to do this, I want it to be perfect.” Saying that, he
planted a soft kiss on his brother’s forehead, moved to sit against the
headboard and beckoned Mokuba to join him. The smaller boy crawled over to him
and nested himself in his brother’s arms. Seto started to brush through
the raven hair with his fingers, an old habit, that always managed to calm them
both down.
 
“I gather you’ve never been with anyone before, right?”
Seto would probably run out and kill that person, if his brother said that he
has been. Because, obviously in Seto’s mind no one was good enough for
his brother.
 
“No, no one could compare to you. No one even came close. So I just
thought, why bother?”
 
Seto snickered “Maybe it’s just that we’re both picky.
Only a Kaiba is good enough for a Kaiba, huh?”
 
“That’s one way to put it.” Mokuba had long since gotten
used to his brother’s somewhat megalomaniac view of the world. It simply
amused him nowadays. 
 
“You said you’ve fantasized about me. Can you then tell me some
of your fantasies?”
 
“I, well,…ehm…”
 
“If you think you are ready to do it, you should be able to talk about
it,” pointed Seto out. Mokuba blushed crimson and averted his head.
 
“Guess you’re right. I just don’t know how to
start.”
 
“Well, take your time. I won’t be going anywhere.” To put
him at ease, Seto started to place soft kisses on his brother’s neck,
which made the younger boy shiver.
 
“Well it did start like this. You would kiss me and say you loved me and
that you wanted me.”
 
“I do, I love you so much.”
 
“Then you would start to kiss me all over my body and I would pull you
closer, going through your hair with my fingers and kissing you back. Then you
would take my shirt off and move lower…lower…”
Mokuba’s words were cut off by his brothers lips, kissing passionately.
Seto was more than a little turned on now. He pulled Mokuba into his lap as he
proceeded kissing him. The younger boy wrapped his arms around his brother,
moaning at the sudden overwhelming contact.
 
Seto pulled back a bit, breathing hard. He was so sure that he had overcome his
feelings for his little brother long ago, at least, that was what he was making
himself believe all those years. And now the realization just hit him that he
shared Mokuba’s feelings completely. His brother’s confession had
triggered a chain reaction and the kiss had broken the dam that was restraining
his emotions. He felt himself harden and wasn’t able to suppress a groan
as Mokuba ground his hips against him.
 
He started to kiss him all over his face once again, but this time more
intensely. Moving on to his neck, Seto slowly lowered Mokuba on his back on the
sheets. He laid him down gently and carefully took his t-shirt off. Seto paused
to admire the sight below him. Mokuba looked up at him with a determined and
challenging look.
 
A voice in the back of Seto’s head yelled: ‘It’s your
little brother! You’re taking advantage of him. This is WRONG!’
But the voice of reason was soon replaced by those of need, love, desire
and… his brother.
 
“Seto, is something wrong?”
 
The young CEO snapped out of it, smiled and shook his head. Then he bent down
and started to place feather light kisses on his brother’s chest. When
he reached his nipples, Seto let his tongue trace little circles around the
one, then the other and rolled the twin numbs between his lips and fingers.
When he oh so gently nibbled on one, Mokuba’s eyes flew open end he
yelped in surprise.
 
“Are you alright?”
 
“Y…yes. Please do that again,” uttered the teen.
 
Seto rose up, smiled and buried his face in raven curls, inhaling his
brother’s scent. He smelled of strawberry shower gel and everything
fresh and pure. Seto wanted to worship his body forever, to erase every trace
of tears from his skin and banish them from his life.
But Mokuba wasn’t that patient. He writhed under his brother’s
weight, trying to bring their bodies closer to each other.
 
Seto noticed his brother’s anticipation and sat up to pull his
turtleneck off. The younger teen first couldn’t decide what was better:
Seto in a super sexy skintight  turtleneck or Seto without it. When the
said garment landed on the floor, the decision was made; without the turtleneck
was definitely better. Mokuba sat up too and reached out his hand, but an inch
from his brother’s chest he hesitated.
 
Satisfied that his brother was enjoying it as much as he himself was, Mokuba
grew more bold and wrapped himself around Seto. He started to kiss and nibble
at the skin between his brother’s neck and shoulder and flick his
fingers over his nipples The CEO shuddered and wrapped his arms around the
younger boy, kissing him fiercely on the lips. He let them both fall down on
the sheets once again and rubbed his hand over Mokuba’s groin. The teen
let out a loud moan and bucked up into the touch.
 
Seto slowly pulled the zipper down and sneaked his hand inside his
brother’s boxers. Wrapping his fingers around the hard shaft, he set up
a slow, but firm pace, not giving in when Mokuba tried to force him to go
faster. Then, when his brother came close to an orgasm, he suddenly released
his grip.
 
“Seto!” The name sounded as an accusation.
 
“Be a little bit more patient Mokuba. I promise you won’t regret
it.”
He then leaned in and kissed the skin on Mokuba’s stomach, while pulling
his jeans and underwear all the way off. The CEO’s head lowered even
more and he engulfed his brother’s member with his mouth. The
teen’s head shot back and his eyes closed in utter bliss.
Seto did not often give head, but when Seto Kaiba did something, whether it was
a business transaction, a card game or sex, he made sure his performance was
excellent. The younger boy entwined his fingers in the chestnut hair and let
out a deep moan.
 
“Oh Seto, this feels so good.”
 
Encouraged by his brother’s words, the CEO took him fully in and deep
throated him. It took only a few seconds until Mokuba came, screaming out his
brother’s name. Seto smiled and licked the come from his lips. Right now
the taste seemed better than anything he had ever tasted.
 
“Haven’t I told you it would be worth the wait?”
 
“Yes you did. And yes it was…Thank you.” They lay next to
each other, silent for a moment, Mokuba still regaining his breath. Then he
broke the silence.
 
“Seto?”
 
“Yes Moku-chan?”
 
“Could…can I return the favor?” Seto hesitated. He was
definitely still very excited, but he was not sure if he could let his little
brother do this.
 
“Are you sure this is what you want?” he asked hesitantly.
 
“Yeah,…well, I’ve never done this before, so I
don’t think I’ll be very good, but I really want to try. I wanted
to for a while now. I’ve often thought about it,” he blushed a
little, embarrassed by his inexperience.
 
Seto took his head in his hands and looked him deep in the eyes.
“Listen Mokuba, everything you do is just perfect. You are perfect.
I’ve never felt as good as tonight, because I’ve never loved
someone as much as I love you,” he paused for a moment.
“I’m just afraid that you’re not ready for this,
that’s all.”
 
“Niisama, I’ve been ready for the last year and probably for my
whole life.”
 
The brown haired boy smiled and kissed his brother’s forehead gently.
“Then you can go ahead, just stop when I tell you to, ok? I don’t
want to come in your mouth.”

The CEO unbuttoned his jeans and pulled them off, while Mokuba was already busy
playing with his nipples. He may not be very experienced, but he was smart and
not as innocent as everyone thought. When you have to mature so fast, you tend
to pick some things up, besides he had fantasized about this moment for so very
long. So he didn’t waste much time.
 
Leaving a wet trace of kisses on Seto’s chest and stomach he slowly
moved down. The first licks were very experimental, but Mokuba found the rhythm
that provided his brother much pleasure surprisingly fast. And in no time the
CEO was writhing under him, moaning and fisting the sheets.
“Moku,…I’m so
close…stop…don’t,” but when he felt that Mokuba
didn’t have the slightest intention to let him go, in fact, he only
increased his assault, the brown haired boy gave up and his protest turned
into: “Don’t…don’t…stop, don’t
stop.”
Then, with a loud moan he spilled his seed in his brother’s willing
mouth. He lay panting for a moment, the vision of his brother’s red and
puffy mouth with the traces of white around it sending powerful aftershocks
through his body.
 
“I thought I asked you to stop?” He tried to sound accusing, but
sounded a bit groggy instead.
 
“Well, you told me to, but I don’t think it was what you wanted.
And I’m your brother remember, I know what’s good for
you.”
 
“Smartass!” Seto leaned over and smacked him on his behind.
Mokuba yelped and wriggled away.
 
“Oh, kinky! I’ve always suspected the whole leather pants and
metal accessories thing was more than just a fashion statement.” Seto
flushed crimson, completely mortified and wonder, not for the first time, if
his brother would be the death of him.
