Summary
     Makoto didn't think Haru-nii-chan would ever punish him like this.
"Makoto," Haru's voice was hard, dark. Disappointed. It made Makoto's body
tense to hear that tone, a small shiver climbing his spine. "What did I tell
you?"
"I-I'm sorry, Haru-nii-chan," Makoto whimpered out pitifully. The sinking
feeling in his stomach immediately worsened when he caught the look on Haru's
face.
"I was worried about you." Haru's words were still edged as he said, "Do you
know how I'd feel if something happened to you? And you know your parents would
kill me."
"Sorry," Makoto repeated again, looking down at the space in front of his feet.
He could feel his eyes start to burn. They always did when Haru scolded him.
Haru had been his babysitter for years now, still was, even though Makoto was
nearly old enough to start middle school. Ever since he could remember, his
parents had been close to the Nanase family. It seemed only natural that their
older son would look after Makoto like the kid brother he never had.
"Kenta wanted to show me his card collection after school and... I... I just
forgot..." Makoto didn't think it would take long to do, so he hadn't told Haru
that he would be visiting a friend's house after school. In the end, when Haru
came to pick him up, Makoto wasn't there. It made perfect sense why Haru was
angry with him, and that only made him feel worse. "I'm really sorry, Haru-nii-
chan..."
Haru heaved a deep sigh, the frown thankfully fading from his face. He set his
hand on Makoto's shoulder and said, in a voice that was a bit gentler, "Things
turned out okay this time, but what you did was still wrong."
Whenever Haru said that, Makoto knew that meant he was going to be punished. If
the recent trend of Haru's punishments continued, Makoto knew he wouldn't like
it. Still, he asked, "W-what are you going to do?"
Haru told him, with no room for argument, "You're going to get a spanking." He
knew it. Makoto hated them more than anything else-- they hurt, and were
embarrassing, and sometimes... "Come here, Makoto," Haru ordered, taking a seat
on the couch.
Makoto swallowed hard. With great reluctance, he climbed onto the couch and
laid over Haru's lap.
"Good boy," Haru said. There was an odd quality to his voice, one that made
Makoto feel very uncomfortable, and... exposed. That uneasiness grew tenfold
when Haru's fingers slipped under his waistband, and pulled down Makoto's pants
and underwear.
"H-Haru-nii-chan!" Makoto yelped in surprise. "Why can't I keep them on...?"
"Hush. This is your punishment today." Makoto did as he was told, and pressed
his lips together.
Haru's hand lifted into the air, and Makoto tensed. No matter how many times
he'd gone through it before, he was never ready for the sharp burst of pain on
his bottom that came with the first smack.
A whimper shot out of Makoto's mouth, and his eyes burned harder. He wondered
how many swats Haru was planning to do this time, but he didn't dare ask, in
case Haru decided to change his mind. Another spanking came, this one firmer
than the last, right on his already sore cheeks.
Makoto bit down his pained noises as the onslaught continued with four more
smacks. His butt was stinging and hot, and Makoto felt the tears starting to
well in his eyes. Sitting down would hurt for the rest of the day already, but
Haru didn't seem like he was satisfied yet.
Makoto knew he couldn't take it any longer after Haru delivered another hard
slap to his bottom. When he only lifted his hand back into the air, Makoto
cried out, "Haru-nii-chan, that really hurts!" Unable to hold back his tears of
pain and humiliation, he sobbed, "I'm really s-sorry, please stop..."
Haru's hand thankfully paused, and came down to rest against Makoto's reddened
butt. "You did a bad thing, Makoto. It's not fair if I let you get away with
it."
Makoto couldn't bear even the thought of another spanking. "I'll do anything
you want, Haru-nii-chan, anything but this." He could hear Haru take a sharp
breath in response.
"...Anything?"
The way Haru asked that made him feel extremely nervous. Makoto quickly added,
"As long as it doesn't hurt."
Haru paused, as if in thought, then finally said, "Okay."
When Makoto looked at his face, there was an even scarier expression than the
displeased frown from before. "On your knees," Haru said, rough, like he was
having a hard time breathing properly.
Makoto could only shake off his nerves, and do as he said. Gingerly sitting on
his knees in front of Haru. It was then that he noticed something strange about
him-- the center of his pants had tented, making a big bulge. Makoto had felt
something hard and assumed it was something in Haru's pockets, but it was
actually...?
Haru carefully pulled the zipper of his pants down, and pulled his erection
free. Makoto gasped as he saw it, and flushed deeply. His... thing had gotten
hard, the way Makoto's did sometimes at night, or when he and Haru used to take
baths together.
"D-do... you want me to touch it?" Makoto asked finally, hushed. The thought
sent a strange zing of excitement to his own groin.
"Yes. You're always so smart, Makoto," Haru praised him. Normally it would make
him happy to hear, but right now it made him more flustered. "You know what to
do, don't you?"
Makoto did, so he nodded and carefully reached out for Haru's swollen flesh. It
felt hotter than his own, and in comparison it was huge, so Makoto felt awkward
trying to wrap his fingers around it. Haru sighed in reply, pushing his hips
upward a bit, and encouraging Makoto to continue.
He'd never seen Haru make an expression like this before, a slight flush to his
cheeks, eyes fluttering closed. For some reason, Makoto kind of liked it. He
began to move his hand, stroking Haru's length like he did his own some nights.
He flinched at the sound of Haru's voice, not expecting him to start talking
again just yet. "Makoto," he said, "you know what this is, right?"
Makoto knew his ears were turning red as he whispered, "A... penis..."
The word seemed to bring a strange smile to Haru's face. "Do you know any other
words for it?"
"I've heard kids say..." Makoto lowered to a whisper, "dick, too."
"Anything else?" Haru asked. Makoto shook his head, embarrassed enough about
those words. "I like to say 'cock.' You should try that one." Haru's low voice
caressed the word, made it sound dirty and adult. Even if Makoto was doing
something he'd only seen talked about in naughty books, saying something like
that felt even more scandalous.
Still, if he complained, Haru would say that it was part of his punishment.
Makoto wet his lips, and tried out the word on his tongue, "...Cock."
Haru took another deep breath, and looked down at him with pleasure. "You're a
fast learner." Makoto blushed, and went back to touching Haru's... cock... The
pink head was wet and glistening as Makoto held the rest in his fist and began
to pump it.
Haru shifted, moving to the edge of the couch. Makoto could see it better now,
the vein pulsing on the underside, the way the tip twitched when he pushed his
thumb against it.
"Makoto," Haru murmured, and Makoto was both worried and excited to hear what
he would say now. "I want you to lick it."
"W-what?!" Makoto yelped, looking up at Haru. He wasn't joking. Licking
Haru's... Knowing that he had to obey Haru's words, he held back his
complaints, and slowly inched forward, sticking out his tongue. He didn't
expect Haru to push his fingers into his hair, urging him forward, nor the
weird sense of anticipation that resulted. His tongue met the too-warm skin of
Haru's cock, and he drew it up the underside to the tip, as if he were
devouring a warm popsicle.
Makoto would never forget the sound that came out of Haru's mouth when he did
that-- a low stifled moan-- or the look on his face-- eyes locked on him, half-
lidded and completely aroused. Makoto didn't understand why it made him feel so
good to see Haru like that, but he did know that he wanted to see more, and
hear Haru moan again.
He eagerly used his tongue, licking his cock up and down, thoroughly wetting
every inch of the sensitive skin. Makoto could tell that Haru liked it a lot
when he pressed the tip of his tongue just under the head, or when he swirled
his tongue around the crown, so he did that the most, until Haru was panting
hard.
Haru had told him to lick, but wouldn't sucking on it be even better? Makoto
felt his own penis throb at the thought of such a thing being done to him, and
with that in mind, he leaned his head forward. Carefully, minding his teeth, he
took Haru's cock into his mouth and sucked hard.
The reaction was almost immediate. Haru's hips jerked forward, making Makoto
nearly gag, and he moaned, "Makoto," aloud suddenly. Now that he was sucking,
Makoto could hear even more of Haru's pleasured voice. "That's good, Makoto...
just like that," he'd say as Makoto tried to take him further. Makoto had to
draw back when it got too tough, but Haru seemed to like that almost as much.
Soon, Makoto was sucking hard as he bobbed his mouth up and down on Haru's
cock. He found that, the more he tried, the more he could take into his mouth
and hear another bit of Haru's praise.
"You look happy, Makoto," Haru purred. Makoto froze right in his movements and
blushed hard. "Do you like sucking my cock that much?"
Makoto's mouth suddenly felt dry, despite the saliva and precome that had been
leaking from Haru's tip. He pulled back and locked eyes with Haru, knowing that
he wanted him to answer, and that it wouldn't do to lie. As embarrassing as it
was, Makoto couldn't hide how hard what he was doing made him, and how much he
wanted to make Haru feel good.
"I like it..." he whispered, "I like sucking Haru-nii-chan's cock."
"You're such a good boy, Makoto... that's why I love you so much." Makoto's
face burned even hotter at those words they'd spoken for years, but now felt
very different. Haru's eyes weren't filled with just excitement, but also real
affection for him.
"I love you, too, Haru-nii-chan," he said shyly, and swallowed Haru's cock once
more, this time working faster. The sloppy sounds were so embarrassing as he
moved, but they were easily drowned out by Haru's groaning as he gained his
speed. Makoto could feel Haru's fingers stroking his hair, and eventually
clenching as his pleasure mounted.
Suddenly, that grip tightened even further, and Haru moved his hips forward.
Makoto found his head held firmly in place as Haru pushed his cock in and out
of his mouth, against his tongue. Not so far that Makoto would choke, but
almost. Makoto moaned helplessly around Haru's cock as he continued, using his
mouth like the sex toy he'd accidentally found in Haru's room last summer.
Haru's harsh breathing reached its peak after a few more thrusts. His pace
slowed, stuttered, and then he was moaning Makoto's name as he came. Makoto
could feel his cock twitch right in his mouth, his semen hitting the back of
his throat as he swallowed it all down, and it was unbelievably arousing.
The throbbing in his groin was impossible to ignore now.
"Hawu-nii-shahnn," Makoto whined, mouth still full as his hands wrapped around
his erection. The warmth of Haru's cock in his mouth only added to his
excitement. Makoto shamelessly jerked himself off on his knees, raising his
hips into his pumping hands until he couldn't stand it anymore, and sobbed as
his vision grew white. A steady stream of pearly fluid shot from his dick,
against Haru's jeans.
Haru's cock fell out of his mouth with a soft, wet pop, and Makoto leaned
bonelessly against Haru's legs. Haru still had his fingers in his hair, petting
him softly while Makoto caught his breath.
"Have you learned your lesson?" Haru asked, once his breath had evened out once
more. It took a moment for Makoto to remember the stinging in his butt, and
everything that had led to the current situation.
Makoto quickly nodded. "O-of course. I won't do anything like that again."
The next time he got into trouble, it would be on purpose.
