****** the importance of ice cream ******
by Sammee
Summary
     In which Kisumi ends up fucking his baby brother, not much else to
     say here.
"Kisumi-onii-chan!"

Hayato flew into his brother's arms the second he was changed, still flushed
pink from the excitement of the day. "Did you see me swim? I really did it!"

His eyes were practically glittering with accomplishment, and Kisumi was
immediately drawn into his enthusiasm. "Yeah, I saw you!" he said, grinning.
"You looked great down there."

"Hehe," Hayato giggled and gave him another squeeze before pulling away. "Coach
Tachibana taught me the backstroke! The other kids said it was cool, too."

Kisumi was extremely proud of him for doing so well despite his anxiety, and he
would have to properly thank Makoto for what he'd done later.

"Tell you what," he said, reaching for Hayato's hand, "we can go somewhere to
celebrate on the way home."

Somehow Hayato managed to look even more thrilled at those words. "Yay! I want
to get some ice cream, Kisumi-onii-chan." With a glowing smile like that,
Kisumi would have given him anything he wanted. Of course, his wallet was
grateful that he'd chosen something so simple.

The local ice cream shop wasn't too much of a deviation from their normal route
home, and Hayato had practically skipped the whole way as he told him
everything about the day's practice.

"So you really wanna go back to the next class, huh?"

At that, Hayato paused. Kisumi was almost worried that his victory of the day
hadn't done much for him in the long run, but then he nodded. "Yeah. I think...
I wanna see if I can do it again, even if it's a little scary. It was fun."

Hayato was a serious boy for his age, always quiet and thoughtful. Kisumi had
truly considered asking him soon whether or not he wanted to continue going to
swim practice. Hayato always seemed so unhappy and nervous in the water, and he
was too timid a child to tell someone outright if he wanted to quit. Therefore,
it was a huge relief to see that today's lesson had given him enough confidence
to look forward to next time.

"Good." Kisumi reached down to ruffle his little brother's hair, making him
pout slightly. "It makes me really happy to hear that. Now, what flavor are you
gonna get?"

"Red bean, of course." Now that wasn't a surprise at all. It was Hayato's
favorite flavor since he'd first tried it, and he was the kind of boy who would
always get the same thing instead of trying something new. Once Kisumi had
gotten him a cone with two scoops of red bean ice cream and something small for
himself as well, they took a seat at one of the benches outside of the small
shop.

The sun was setting and the summer heat was starting to die down, but it was
still pretty warm. Kisumi turned to his little brother beside him, who was
licking happily at his cone. "Why do you always want to sit outside?"

Hayato frowned. "It's too cold in there. Ice cream tastes better when it's
warm," he said sternly. Kisumi preferred it when he didn't have to worry about
his ice cream melting, but it was Hayato's treat, after all.

After a few minutes of mostly silent enjoyment, Kisumi chuckled as he watched
his little brother suffering from brain freeze after eating too quickly. "You
really like red bean ice cream, don't you, Hayato?"

"Uh-huh! It's the best."

Kisumi looked down at him curiously. "What do you like the most about it?"

"Well, it really tastes good, but..." Hayato stopped mid-thought, and began to
fidget slightly.

"Yeah?"

He was hesitant when he finally said, "I really like the color." If Kisumi
remembered correctly, the only times Hayato seemed unsatisfied with his
favorite flavor was when the red bean paste wasn't blended completely through,
and it was more white than pink. "But that's a weird reason to like an ice
cream flavor..."

"It's not weird," Kisumi told him, not wanting Hayato to be discouraged by
something so small. "If things look good, that makes them taste better, you
know!"

"Really?" Hayato was skeptical, so Kisumi continued, trying to convince him
that it was true.

"Yeah. Sometimes, people even can be fooled into thinking they're eating a
different flavor just by changing what it looks like. Like, if you put food
coloring in vanilla ice cream to make it look like chocolate, some people would
think it's actually chocolate ice cream. It's science!" Kisumi told him
confidently. At least, that's what he had read somewhere once. Either way,
Hayato was blown away.

"Wow. Kisumi-onii-chan, you're so smart!"

Kisumi allowed himself to bask in his little brother's praise for a moment.
"See, it's not weird to like it for the color then, is it?"

That made Hayato smile shyly, and Kisumi's chest swelled at the sight of his
cute expression. "I guess not."

"Wah, it's dripping!" Kisumi yelped when he saw the sides of Hayato's cone
beginning to seep melted ice cream. He quickly grabbed Hayato's hand and moved
it over the sidewalk. Luckily, only a small amount had gotten onto his clothes.

Hayato grabbed the napkins that Kisumi had brought with them to staunch the
flow. Then, he brought his fingers to his mouth, licking off the sweet cream
there in a rather thorough manner, sucking each finger clean. Kisumi let out a
breath he'd been holding, feeling as though he'd seen something he shouldn't
have.

"Did... you use all the napkins?" Kisumi asked, looking around to see if any
remained. When he'd grabbed Hayato's cone, he'd spilled some on his hand as
well, and now he was starting to feel sticky.

"I'll do it," Hayato said, grabbing Kisumi's hand and leaning over. He wasn't
sure what Hayato was planning to do without any napkins until about half a
second before it happened, and his breath caught in his throat. Hayato's tongue
flicked out, following the path left by the melted ice cream down Kisumi's
palm. Then, he took his two forefingers into his mouth, sucking lightly and
pushing his tongue between them to remove all of the sugary stickiness from his
skin

Finished with the task, Hayato drew back, looking quite pleased with himself
for helping. "There you go, Kisumi-onii-chan!"

"H-Hayato..." For some reason, Kisumi's voice came out a little shaky. It was
probably just because of how surprising it was for his little brother to do
such a thing. He cleared his throat, and told him, "You shouldn't do that.
Licking... other people is..." Hayato looked up at him, confused and starting
to worry that he'd done something very wrong. "Well..." It would be hard to
explain it exactly so that he would understand, so instead Kisumi tried smiling
reassuringly. "Just don't do it to anyone other than Onii-chan, okay?"

"Oh... okay, I won't."

Hayato still seemed slightly dejected, so Kisumi distracted him with questions
about the other kids at the swimming class until they'd finished eating. He had
returned to his high spirits by the time they got home, and was excited to tell
the rest of the family about his day.

Once Kisumi had finished some homework and studied a bit after dinner, he was
surprised to see how late it was. "Guess I should get to bed soon..." he
sighed. He had really been hoping for some free time, but he didn't have too
much to do tomorrow, and going to school on less than a full night's of a sleep
was the worst.

He sighed again, and decided to just go ahead and get ready for bed. He was in
the middle of changing into his sleepwear when a small knock came at his door.

"Kisumi-onii-chan...?"

It was Hayato. Kisumi was curious what he was still doing up so late, but maybe
he'd been unable to fall asleep, or had a nightmare.

"Hey, Hayato, come on in." Hayato's face was flushed and full of worry, and his
hands gripped tightly at the edge of his long t-shirt. Kisumi frowned, putting
a hand on his small shoulder. "What's wrong?"

Hayato only bit his lip and moved to sit on Kisumi's bed. He didn't say
anything for a while, so Kisumi gently prodded him, "What is it? You can tell
me."

Finally, Hayato nodded slowly, and blurted out, "I had a weird dream... and
when I woke up, m-my..." His face flushed even deeper red, and he lifted up the
edge of his shirt. "My thing was all weird!" Sure enough, Kisumi could see the
slight bulge in his shorts.

It took a few seconds for it to really register. Kisumi hadn't been expecting
to give this sort of talk to his brother for another year or two at least, so
he was caught ill-prepared. His silence only made Hayato more nervous, and he
began to tremble slightly.

"Ah, don't get upset, Hayato," Kisumi told him, before he started to cry. His
brother was a bit weak when it came to being honest, and whenever he was
embarrassed or scared, tears were likely to spill. "That is, uh, w-well,
totally normal for boys..."

"R-really?"

"Yeah," Kisumi said reassuringly. "It even happens to me. It's completely
natural."

"How do I make it stop?" Hayato asked, still unhappy, although at least
relieved that it wasn't a problem with just him.

Kisumi swallowed, feeling awkward suggesting this to his baby brother. "Uh,
well... if you touch it, eventually it should... go back to normal. Or you
could take a cold bath."

Hayato shook his head after the last one. "I don't want anyone to ask why I
took another bath so late..." Of course not, that had been why he'd come to
Kisumi in the middle of the night instead of doing anything else. "And... I
tried touching it before, but it felt weird."

Kisumi felt slightly uncomfortable. "Well, try it again. I'll turn around."

"Okay..." Hayato said carefully, and waited for him to do so. Once Kisumi was
facing the wall, he could hear Hayato shift on his bed, and pull down his
pants. Then, came a quiet sound, and a sharp breath. "It's... weird..." Hayato
murmured between huffs.

"Just keep touching it, okay?" Kisumi told him. For some reason, his heart was
beating more quickly in his chest than before, and his body was heating up...
He was sure it was just because it was embarrassing to have to listen to
Hayato's quiet whimpers as he continued to touch himself, and not be able to
take a peek... No, wait, what was he thinking?

Hayato was his brother, and it was his duty to... to...

"Kisumi...onii-cha...ahn!" Hayato continued to moan as he rubbed himself, and
he was trying to talk to Kisumi at the same time, which wound up making it
sound rather... erotic.

Geez, what had gotten into him?! "W-what is it, Hayato?"

"I can't touch it anymore... I feel like I'm gonna... p-pee," Hayato's voice
shrunk to an embarrassed whisper.

"You won't pee, I promise. Just keep going."

"I can't! It's too weird!" Hayato had finally reached the level up
embarrassment where he'd began sniffing, and Kisumi could hear his tears
incoming. Ugh... Kisumi prepared himself, and turned around to look at his
little brother.

Hayato was leaning back on the bed, with his shorts pulled to his knees. His
small cock was standing stiff between his legs, flushed almost as red as his
face. And speaking of his face... Kisumi had to swallow again, for a different
reason, looking at his little brother's tearful and upset expression.

"Kisumi-onii-chan..."

"I... I'll help you, Hayato. You trust Onii-chan, right?" Kisumi gave Hayato
his most confident smile, and soon, he was given a small nod in response.

Sitting at the edge of the bed, Kisumi took a deep breath. Nothing was weird
about this, he told himself, feeling uncharacteristically anxious. He was just
helping out his little brother with a very male problem. Besides, Hayato was
the one who was scared, and if Kisumi acted like there was something wrong, he
would just make him feel more uneasy.

With that in mind, Kisumi made sure to keep a comforting expression on his face
as he reached for Hayato's cock. "It's okay," he said, as Hayato made a little
whimper. Hayato's cock was about as big as you'd expect for a boy his age, the
foreskin still clinging firmly to his shaft. Gently and using only a few
fingers, Kisumi began to pull it back.

Hayato's hips jumped at the sensation, and he made another small, suffering
noise. Kisumi used his other hand to pet Hayato's hair, a gesture that helped
calm him down a bit.

"S-stop..." Hayato began to whimper as his big brother kept stroking his cock.

"Shhh," Kisumi murmured, rubbing a bit faster. "What you're feeling is totally
normal."

One of Hayato's hands reached out for Kisumi's shirt, grabbing it tightly as he
clenched his eyes shut. "Ohhh..."

"Good, Hayato," Kisumi breathed. His eyes were trained on his face, watching
the way his forehead scrunched up, as if in torment, whenever Kisumi moved his
hand. Hayato bit lightly at his lip when he tried to hold back his moaning, but
sometimes his mouth just fell open and he gasped. "You're so cute..." Kisumi
couldn't stop thinking it, but it was a surprise when he actually voiced this
thought. Then, he wrapped his whole hand around his little cock and pumped it
in his fist.

That made Hayato's eyes fly open with surprise, and his hands press against his
mouth to stifle his moaning. "Kisumi-onii-cha..."

But Kisumi only moved his hand faster, now that Hayato was definitely about to
come. He was panting, too, and when Hayato finally squealed and let loose a
small stream of semen, a hot wave of lust shot through him.

Quickly, Kisumi pulled his hand away and moved across the room to gather
himself and retrieve a few tissues. He put on his best face once more, and
handed the tissues to Hayato. "See? You're all better now."

Hayato was still reeling from what had just happened, but he nodded, dazed. He
soon sat up and wiped himself off, still blushing from both the activity and
embarrassment, but he was definitely more at ease than he'd been when he
knocked. Once he'd calmed down completely, Hayato looked up at Kisumi, smiling
gratefully until his expression turned into one of concern.

"Oh no. You've got a problem, too..."

Kisumi had been trying to deeply ignore that and coughed when Hayato mentioned
it. "Don't worry about me, Hayato. I know how to get rid of it. Just go on back
to bed. You're okay now, right?"

Hayato's frown only deepened, and then he looked guilty. "But... it's my fault,
isn't it?"

Gulp. Kisumi's blood ran cold at that thought. Even he didn't want to admit
what his reaction likely pointed to, but his own little brother didn't
seriously think that he was...

"I mean, I passed it on to you, right?" When Hayato looked up at him, he seemed
so sure of it that Kisumi didn't have the heart to tell him that he was
completely wrong. Nobody 'passed' an erection like a cold, or the flu, but...
explaining how men got aroused and then trying to tell him why his big brother
had gotten this way while jerking him off... Kisumi certainly didn't have the
guts to go through that right now.

"Uh... yeah, so... if you stay here, I'll just pass it on to you again," Kisumi
said finally. Anything to stop the conversation there and send Hayato back to
his room was honestly a victory.

At this problem, Hayato looked truly stumped. He was just about to give up when
a lightbulb seemed to go off in his head. "Then, what if we both get rid of it
at the same time?"

"But, you're fine right now. Do you really wanna go through that again?" Hayato
had been completely distraught the first time, but now he was acting like it
was no big deal to try it again. Kisumi soon realized there would be no way
around it... He was a young boy who'd just discovered the pleasures of
masturbating. Of course, he didn't find having to jerk off again a troubling
prospect.

In a last ditch effort, Kisumi asked, "But how are you going to get one?"

Hayato thought it over for a few seconds, and then told him, "Um, well,
sickness passes faster when you share your food and drinks, right? So..."

Kisumi's heart started to beat out of his chest, and down southward there was a
different sort of reaction... He felt unbelievably guilty, but his gullible
little brother was just too adorable, and he was too weak to refuse his baser
urges. "W-we can try it."

Hayato's small hands quickly slipped underneath the waistband of Kisumi's pants
and tugged them down. "Woah, Kisumi-onii-chan. It's... big!" While his dick was
certainly above average, it probably looked massive to a boy Hayato's age.

After a timely inspection of his length, Hayato dipped forward, and pressed his
tongue to the underside of his cock. Kisumi had to suppress a groan at the
sight, as Hayato began to lick long lines up and down, eagerly trying to
'catch' his sickness.

Hayato's expression changed slightly as he looked up at Kisumi's face, and he
pulled back. Kisumi almost whined at the loss of the stimulation, no matter how
wrong it was. "That weird dream I had was kind of like this..."

Kisumi froze when he heard that. "What?"

"W-well, not exactly like this." Hayato blushed as he remembered it. "Uh... I
was eating some ice cream, but then, it started making noises when I was
licking it. And then it turned out that you were in the ice cream..."

While that sounded like an extremely odd dream, the fact that his little
brother had dreamt about licking him in any form was a bit worrisome. Was it
all because of earlier...?

But Kisumi's thoughts were interrupted when Hayato began to lick at his cock
once again. As though it were a delicious popsicle, Hayato's tongue ran
tirelessly over its length, flicking against the tip. Kisumi's head was
spinning from the teasing way Hayato was touching him; his licking did just
enough to stimulate every nerve on his cock, but not enough to give him any
relief.

"Ah," Hayato said in surprise, his face tinting pink slightly. "Kisumi-onii-
chan... I think it worked."

Did that mean... Hayato had actually gotten an erection from licking his dick?
Of course, Hayato thought such a thing was utterly inevitable, and didn't seem
bothered at all. Instead his main concern was what would happen next. "But...
how are we gonna make sure we both finish at once?"

Kisumi felt utterly guilty at the thoughts he was having. If Hayato thought it
was weird or said it hurt, Kisumi would stop immediately, he told himself. It
was just the sort of compromise that he needed to give in to such a horrible
idea... He sucked in a breath, and said, shakily, "Leave that to me. You're
gonna have to let me do something that sounds kind of strange though."

"Okay..."

Kisumi retrieved the small bottle of lube that he usually used for
masturbating. Hayato was already on his knees for him like he'd asked,
cautiously looking over his shoulder. Kisumi almost couldn't believe what he
was about to do, but here he was, saying, "I'm going to put something in your
butt," as he pressed a lubed finger against his little brother's hole.

"T...that's..." Hayato glanced back at him again, still feeling unsure. Still,
he nodded, willing to trust him for now. Kisumi slowly pushed it inside and
began to prepare him thoroughly. His little butt was tight, and the last thing
Kisumi wanted to do was end up hurting him...

After a good while, Kisumi was able to push three fingers in and out of
Hayato's hole with relative ease. "You okay?" he asked him again, and Hayato
huffed out that he was fine. When Kisumi moved his fingers a certain way,
Hayato's lithe body would twist slightly, and his breath hitched loudly.

Kisumi thought that he would probably be alright now, and pulled his fingers
out. Still tight, but if he had to wait any longer, he was slightly worried
about the anticipation being too much to handle.

"Hey, Hayato..." he said, "do you still want to do it like this?"

Hayato turned to look at him, his cheeks still flushed, but this time Kisumi
found a strange glimmer of excitement in his eyes. "It... feels kind of good. I
wanna do it."

If he said it like that, Kisumi wouldn't be able to resist...

Hayato was too cute, and Kisumi didn't want to let anyone else have him. It was
a strange thought to come to after all that had happened, but after nearly
losing him Kisumi had begun to feel more protective, to a slightly abnormal
degree. What he was doing now was even more abnormal, but it provided him a
very selfish feeling of comfort to have Hayato like this.

"Come here," Kisumi said. He reached out and pulled Hayato over his hips, just
holding him in his arms like that for a while.

Hayato started to shift after a bit, clearly confused. "Kisumi-onii-chan...?"

"Sorry. It's all Onii-chan's fault you're scared of the water..."

Hayato's eyes widened slightly when he heard him say that. "No, it's not! You
saved me, remember? Besides, I was the one who got too close to the edge."

Hayato's words didn't do much to assuage any of the guilt Kisumi had, however.
He was just a kid after all, and that... and this, too, was all his older
brother's responsibility. "You know, I was really scared back then."

"Huh? Why?"

"Because you could have gotten hurt, or even worse." Kisumi looked down at
Hayato's round face, and found a sort of possessiveness rising inside him
again. "Even right now... it scares me to think about how close I was to losing
you, Hayato."

Frowning, Hayato stared back at him, and brought his hand to Kisumi's jaw. He
leaned up and kissed him gently on the lips, then smiled. "Don't worry, Kisumi-
onii-chan! Coach Tachibana will teach me how to swim, and then you won't have
to be scared of me falling in the water anymore."

Kisumi was taken aback by his adorable brother's naive words. He was too sweet,
so much so that it hurt Kisumi to think about him out in the world. Hayato
didn't understand that he wasn't worried just about him drowning, but about him
ever being in danger, or ending up scared, or hurt. Whenever Kisumi imagined
those things, he never wanted to let go of Hayato's hand in the morning.

But, he smiled at Hayato, who had done his best at comforting him, and leaned
down to return his kiss. Kisumi's was a bit different, however. He cupped
Hayato's jaw and gently pulled open his mouth, then turned his head slightly
before kissing him, making their lips line up. He had given Hayato CPR like
this on that day and his mouth had felt so cold against his that Kisumi had
almost lost it. Tonight, it was so much better; Hayato's pink lips were warm
and petal soft against his own, earnestly moving in response to him.

Kisumi gripped Hayato's hips, and tugged him forward over his cock. "When
you're ready, just... push your butt down onto me, okay? Slowly. It might be a
little uncomfortable at first, but--" Kisumi couldn't even finish his sentence
before Hayato began to move, his hole rubbing right against the head of his
cock.

"Nnhhh..." Hayato breathed out, his eyes tearing up slightly as he let himself
sink down and take Kisumi inside.

"N-not so fast, Hayato," Kisumi said, his voice breathless, nearly begging.
"You're too tight..." Kisumi ground his teeth together in an effort to restrain
himself; the feeling of Hayato's small body enveloping his cock was so amazing
that it was hard not to help him along.

Despite the discomfort on his face, Hayato pushed himself further. Kisumi's
hands gripped Hayato's hips tightly before he could do anymore. "Just, wait,"
Kisumi huffed. Hayato was surprised to see him in such a state just from moving
a bit, but listened to him anyway. After a short break, Kisumi removed his
hands and let Hayato continue. This time much more considerate, the boy moved
at a slower pace until he reached the very base.

However, the one having trouble now was definitely Hayato. His face was
flushed, and his chest heaved with each breath he took. With his butt stretched
to the limit and stuffed full of his big brother's cock, it was no wonder why
he was so worn out already.

Kisumi was determined to let him have some time to get used to it, but it was
getting increasingly hard for him to keep still. Hayato had never been
penetrated before, and his virgin hole couldn't stop twitching around the
intrusion. God forbid if Hayato actually moved before he was ready-- Kisumi
didn't know if he'd be able to stop himself from rutting him like an animal.

Eventually, Hayato's face had returned to a more natural shade of pink, and his
breath wasn't quite as labored. "Ready?" Kisumi asked in a whisper.

"Y-yeah..." Hayato still sounded a bit nervous, but Kisumi could hardly wait
anymore. He clutched at Hayato's hips again, to keep him still as he began to
pull out. At first, all he could bear were shallow thrusts, in and out, quick,
as he watched Hayato's face.

Hayato reached out for him after the first few thrusts, pressing close to his
chest. Kisumi craned his neck to give his little brother another kiss, this one
more sloppy. He licked at Hayato's lips first, then pressed their mouths
together and slid in his tongue. The distraction was welcome for Hayato, who
thankfully began to relax around Kisumi's cock as the kiss continued. Like
this, Kisumi would be able to thrust harder into Hayato's delicious heat
without as much worry.

"Kisumi-onii-chan," Hayato groaned as he sped up his movements, drilling into
his little hole with greater urgency.

Kisumi couldn't believe how amazing it felt to have him like this. Hayato was
hotter and tighter than anything he'd ever experienced, and his expressions of
enjoyment were just as enrapturing.

"Ah..." Hayato's mouth had fallen open as he panted, and a sliver of drool
began to drip from his lips. His face was flushed, and his eyes were unfocused
on what was in front of him.

It all just encouraged Kisumi to steadily increase the intensity. He pressed
his fingers into Hayato's slim hips and pulled him into his thrusts, unable to
stop himself from sounding utterly needy as he said, "Move your hips too,
Hayato."

Hayato nodded after a slightly delay, and began to roll his hips on his own.
Watching him move was just as arousing as the rest of the experience, and
Kisumi didn't know where to look.

"How is it? Do you like it?" Kisumi asked him quietly. He wasn't quite sure
whether or not he should hear the answer right now, but it would be better to
find out if he hated it now rather than later...

"It's good." Hayato's voice was quiet, but enthusiastic. "I think I really like
it...!"

Kisumi's mouth went dry at those words. Oh man, he shouldn't have asked after
all... Now that Hayato had said such a perverted thing in a sexy voice, he
wanted to give him even more. Kisumi gripped Hayato yet again, this time
hooking his thighs and supporting his weigh as he stood up. Hayato quickly
linked his hands around Kisumi's neck, surprised by the sudden movement.

Kisumi took two steps until Hayato's back was against his bedroom wall, right
where he wanted it. Panting wildly, Kisumi pushed Hayato's legs back a little,
making the curve of his perfect little butt even more apparent. Then, Kisumi
began to thrust into his hole once more, pinning him against the wall.

"Feels good, huh?"

"A, ahhh..." Hayato could only moan in response as Kisumi's cock continued to
pound him, clinging tightly to his neck. Kisumi couldn't even feel bad about
doing this right now, not when Hayato had admitted to enjoying it, and
definitely not when it felt so damn good.

"W-what about... Kisumi...onii-chan?" Hayato panted out with noticeable effort.

Another wave of desire washed over him to hear Hayato wanting to know if he was
enjoying himself. "Yeah," he breathed. "Yeah, Hayato, you feel great." Great
was an understatement; Kisumi felt like he was on the brink of coming every
time he plunged deeper into Hayato's ass.

Hayato's grip tightened and he started to whimper uncontrollably, his dick
dripping with precome. Kisumi squeezed at Hayato's soft thighs, leaning closer
to his face. "Almost there?" he murmured, and Hayato nodded, brow furrowed.
"Onii-chan, too..."

Kisumi could feel Hayato's body suddenly tense around him, and he bit his lips
tightly so he wouldn't groan. Hayato whimpered pitifully as Kisumi's length
pushed into him, deeply, and he finally reached his end. "O-ohhh," Hayato
whimpered loudly as his cock pulsed and his orgasm hit.

Kisumi could barely move with Hayato's ass clenching him so tightly, but he
dipped down to steal another kiss, tasting him fully. His own climax was
quickly approaching as well. Kisumi pressed his face into Hayato's neck,
breathing hard. "Hayato," he gasped, raising his hips slightly, and that was
all it took to send everything crashing down over him. He came hard, filling
Hayato with his seed.

It took a few minutes before Kisumi caught his breath and set Hayato back onto
the bed, pulling his softening cock free. Immediately, his semen started to
drip out of Hayato's gaping hole, but Kisumi  began to wipe it up with another
set of tissues.

Hayato looked like he was on the verge of nodding off, and Kisumi pressed a
soft kiss to his forehead as he continued to clean him. "Don't fall asleep yet,
Hayato." Kisumi had wiped off their fluids, but he definitely needed a thorough
bath in the morning...

"Mmm..." Hayato blinked sleepily, then closed his eyes and turned on his side.
"I'm too tired to go back to my room, Kisumi-onii-chan... Let me sleep with
you."

Well, it certainly wasn't the worst thing that he could do after what he
already had... Kisumi decided to allow it, and moved into the bed beside him,
pulling up the covers up to Hayato's chin. Within a few minutes, he was already
passed out.

In the morning, Kisumi made sure that he was the first one up so that he could
drag Hayato to the bathroom.

"You okay?" Kisumi asked while shampooing Hayato's hair. There were light marks
on his thighs from where Kisumi had grabbed him the night before, which made
him feel even worse about what had happened. He'd totally lost control...

Hayato nodded. "Uh-huh. It hurts a little, but not that bad."

Kisumi looked away from Hayato's innocent face, mumbling, "Sorry..."

"Oh, no, it's okay, Kisumi-onii-chan!" Hayato beamed sweetly up at him, and
Kisumi pulled him into a short hug.

Once Kisumi had rinsed Hayato's hair, he spoke to him seriously, "Hey,
Hayato... Don't tell anyone about what happened, okay?" Hayato's mouth curled
downward into a curious frown, but Kisumi gave him a smile. "It's a secret
between you and Onii-chan, okay?"

"Hmm, okay."

"Pinkie promise?" Kisumi held out his pinkie, and Hayato was more than happy to
oblige him, linking their fingers together.

When he picked Hayato up after school, Kisumi couldn't stop regretting the
night before. The boy wasn't too sore to run over and give him a big hug, as
always, but Kisumi took him by the ice cream shop again anyway. He still had
some extra cash on him, and Hayato was ecstatic when he'd asked if he wanted to
go.

"Red bean again?" Kisumi asked, and Hayato nodded firmly.

Once they'd picked it up, Kisumi fondly watched his little brother eat his
treat, this time in a paper cup. "It's really good!" he said happily.

After finishing his ice cream, Hayato swung his legs and looked up at him. "Do
you know why the color of red bean ice cream is my favorite?"

"Huh?" Kisumi wasn't prepared for a question like that out of the blue, and
while he was curious, he'd just assumed he just liked how it looked. "No, why
is it?"

Hayato grinned sheepishly and said, "Because it's the color of Kisumi-onii-
chan's hair!" Kisumi blinked. That was the last answer he would have expected,
and before he could say anything in reply, Hayato surged forward to embrace him
again. "I love you, Kisumi-onii-chan!"

Kisumi couldn't help but smile at Hayato's infectious cheer. "I love you, too,
Hayato." He softly ran his fingers through his short hair and held him tightly,
thinking that the boy was definitely the light in his life, and so much more
than that still. He sighed helplessly, and murmured too low for Hayato to hear,
"I love you so much..."
