****** After School ******
by YukiRose
Summary
     Seokjin asks to see Jungkook after school for some after-school
     sessions.
Notes
     Requested by an anon on Tumblr.
“You wanted to see me, Mr. Kim?”
Seokjin smirked at the voice behind him in the doorway. He was just putting
some books into his bag, getting ready for an extra session with his most
troublesome student, Jeon Jungkook. He left a “detention slip” on his desk,
letting him know it was time for another class. Jungkook was only obedient when
Seokjin asked to see him after class.
“Yes… come in,” he called over his shoulder. He heard feet moving behind him
and a book bag hit the floor. He put the last book into his bag as he felt two
arms reach around him, already fingering his belt buckle.
“Did I do something wrong, Mr. Kim?” he whispered into Seokjin ears.
“Yes… You were a distraction to the rest of the class today. You made it hard
for people to focus,” he said. Jungkook purred into Seokjin’s ears.
“A distraction to the students… or the teacher?” Jungkook asked, beginning to
unbuckle Seokjin’s belt. Such a hyper kid… Seokjin turned around and placed his
hands on Jungkook’s hips.
“That’s no way to speak to your teacher,” he said, flipping them around so that
Jungkook was the one being pressed against the desk. He connected the two of
their lips in a kiss, Jungkook wrapping his arms around Seokjin’s neck.
Seokjin let his fingers trace their way down to Jungkook’s ass, giving both
cheeks and tight squeeze. Jungkook moaned into the kiss, already grinding is
hips against Seokjin. This kid was always so eager.
Seokjin began working on getting Jungkook’s shirt off while Jungkook finished
getting the belt off, letting it fall to the ground. He unbutton Seokjin’s
pants, reaching his hand in and giving Seokjin’s half-hard dick some long,
tight strokes. Seokjin peeled Jungkook’s shirt off, letting it fall to the desk
behind him. He ran his fingers over Jungkook’s perked nipples and began working
on his pants as well.
Jungkook managed to get Seokjin’s shirt off in a matter of seconds, and a few
seconds later, his pants and underwear dropped to the ground, leaving him fully
exposed to the elder teacher. He quickly kicked off his shoes and slipped off
his socks. Seokjin leaned back so that he could take a look at Jungkook’s body.
Every little muscle.
“Beautiful…” he said under his breath. Jungkook bit his lip harshly, then
dropped to his knees. He gave Seokjin a smile before pulling his pants and
boxers down, making them both exposed. Seeing Seokjin’s length slowly get
harder was always fun for Jungkook.
“Should I pleasure you first?” he asked. Seokjin chuckled and shrugged.
“Nobody’s stopping you,” he said. Jungkook smirked before giving Seokjin a long
lick from his base to his tip, letting his tongue trace along the vein on the
underside. He licked his tongue around the tip before wrapping his lips around
the head of it. He kept eye contact with Seokjin as he moved his head lower
down the length.
Jungkook, being the impatient kid he is, didn’t take a very long time to
quicken the pace. Seokjin was always impressed by this kids abilities. He
always gave Seokjin the best head ever, and he knew how to ride Seokjin until
they both saw stars. Seeing Jungkook take him fully into his mouth without even
a gag was intoxicating. Jungkook was somehow able to keep his eyes locked on
Seokjin as he twisted his mouth all up and down Seokjin’s length, almost like
he did it for a living. Just when Seokjin was starting to get somewhere,
Jungkook pulled back.
“I don’t want you to cum like this. I want you to cum inside of me,” Jungkook
said. Sometimes Seokjin couldn’t tell if Jungkook liked to talk dirty, or if he
was just blunt. It was in his personality to just be honest and not care what
people thought about it, but how could anyone say something like that so calmly
like it was just part of normal conversation and not think that it was talking
dirty?
Seokjin nodded and pulled Jungkook up. When they first started this little…
arrangement… Seokjin would take his sweet time prepping little Jungkook, making
sure he was stretched out enough and ready for him, but as they got used to
each other and started seeing each other on a normal basis, they tend to skip
that part and just use a little extra lube. Jungkook didn’t mind the tightness
or the little bit of pain. If anything, it just heightened the experience for
him.
Seokjin pulled the lube out from his desk drawer. He always hid it in the very
back behind a bunch of old dusty folders that came with the desk when he
started teaching. He sat down on his desk chair and motioned for Jungkook to
come sit on his lap. Jungkook silently obeyed.
Seokjin squirted a little bit of lube onto his fingers and he lifted Jungkook’s
hips up so that he could apply a generous amount to Jungkook’s puckered hole.
Jungkook then took the lube out of Seokjin’s hand and applied the lube to his
dick himself, using his little fingers to spread the lube all over, and then
using his palm to give him a few pumps. When they were both satisfied with
their work, Seokjin pulled Jungkook up and Jungkook aligned his entrance with
Seokjin’s dick, sliding down the length.
He didn’t give himself much time to adjust. The second his muscles felt a
little bit relaxed, he began grinding his hips into Seokjin’s, the tightness
making Seokjin groan. Jungkook smirked. He liked pleasuring his teacher. It
made him feel special to make Seokjin feel good in a way that no one else
could.
“Mr. Kim, please teach me something new today,” he said. Seokjin bit his lip
and cocked his eyebrow.
“What do you want to learn?” he asked.
“How can I get you to moan my name?” Jungkook asked, looking at him with a big
smile and clear eyes, like he wasn’t slamming his ass down on Seokjin’s dick at
all. Seokjin smirked and grabbed Jungkook’s hips and pulled him up a little,
making him arch his back. He directed Jungkook’s hips down as he thrusted up.
“Like this,” Seokjin answered. Jungkook continued to let Seokjin guide his
hips, realizing that this angle made is very, very easy for Seokjin to hit his
prostate. They kept a steady medium pace.
There was something different about this time. Usually they would be quick to
pounce on each other, and even though Seokjin was gentler with Jungkook in the
beginning, they would quickly get themselves to a place where they were going
fast, hard, and rough, both of them moaning and groaning, and neither of them
would last long.
This time was different though. They kept the same medium pace for a while,
getting used to this new position that Jungkook was quickly falling in love
with. The room was filled with pants and little whimpers, not moans and yelling
(Jungkook was pretty loud usually). Seokjin could feel Jungkook’s thighs start
to quiver and worried that he was about to give out. He looked up at the sweaty
teenager.
“Do you need a break?” he asked. Jungkook shook his head violently and picked
up the pace slightly. His eyes were shut closed, something he did when he felt
a lot of pleasure. Even though they weren’t going very fast or hard, Jungkook
seemed to really enjoy it, so Seokjin let Jungkook do whatever he wanted.
“Mr. Kim… I want to cum…” Jungkook begged, whimpering.
“Me too baby… Let’s go faster…” he said. Jungkook nodded his head, moving his
hips at a faster pace as Seokjin began thrusting up with a little more force.
Soon they were back to their normal selves. Their skin was slapping together
harshly (so much that Seokjin wondered if either of them would get chafing).
The sound of Jungkook’s ass slamming down into Seokjin’s lap filled the room,
along with the whimpers coming out of Jungkook’s mouth. He let out a little
half whimper, half scream with every thrust.
Seokjin loved that sound. Jungkook did it a lot. Whenever they were being a
little rough, Seokjin could always tell when he was hitting Jungkook’s prostate
and that he was close by the sounds he made. He was loud in bed (or in their
case, in the classroom), but he let out little whimpers with every thrust. It
just seemed to heighten each thrust for Seokjin, to hear a little whine each
time he move his hips.
“Jungkook… I’m not going to last much longer…” he warned. Jungkook’s hand
reached down as he started to stroke himself.
“Mr. Kim… please cum inside of me… I want to feel… your cum inside me…”
Jungkook said between whimpers. With this blessing, Seokjin pressed into
Jungkook’s with a little more vigor, allowing himself to finish inside the
student.
The feeling of being filled with his teacher’s sticky cum sent Jungkook over
the edge, and he came on his hand, but mostly on Seokjin’s stomach. As usual,
Jungkook was pretty loud when he finished. He collapsed onto Seokjin’s chest
and his body went limp. Seokjin held him tightly in his arms until they both
caught their breaths.
A minute or two later, after Seokjin felt the blood go back to his brain, he
pushed Jungkook away slightly so that he could see his face.
“You know you don’t have to call me Mr. Kim while we have sex, right?” Seokjin
asked. Jungkook weakly chuckled.
“I like calling you that,” Jungkook said. Seokjin raised an eyebrow.
“Why?” he asked. Jungkook smirked.
“I like that fact that I can say that I’m fucking my teacher. It’s hot. I mean…
I wouldn’t say it… because then you could go to jail… but I like that it’s an
option,” Jungkook said. Seokjin chuckled, rubbing his hand up and down
Jungkook’s back. His dick was still inside Jungkook, but it was getting softer.
They were having a real conversation now, and to Seokjin, this was always the
best part.
“Speaking of which, about this paper coming up…”
“No, you cannot get an extension on it,” Seokjin cut him off. Jungkook pouted
and pretended to pound his fists on Seokjin’s chest, playing the ‘I’m cute and
little and innocent’ card. This was now the second time that Jungkook made
himself look like a sweet little boy while he had Seokjin’s dick inside of him.
Seokjin had his sperm on his stomach. How was that even possible…?
“Why not?” Jungkook whined.
“Because, the school is starting to wonder why your grades are going in later
than everyone else’s but your still getting A’s,” Seokjin said. The entire
school’s grading system was online and it updated whenever a teacher put in a
grade for a student. The school could see the Jungkook’s grades in Seokjin’s
class was going in about a week after everyone else’s but he still had a
perfect grade in the class. Jungkook hummed.
“Then just give me the grade without the paper,” Jungkook suggested. He was
joking… a little.
“I can’t do that. I have to put your paper into your portfolio after I grade
it, dumbass. People would get suspicious,” Seokjin said. Jungkook cocked his
head, only now remembering that every student has a writing portfolio.
“Portfolio… Only our papers go in there, right? Not our homework?” Jungkook
asked. Seokjin hesitantly nodded his head.
“Yeah…” he said.
“Well then just give me an A on all the homework so that I can write the
paper,” Jungkook said. Again he was joking… sort of. Seokjin sighed and shook
his head.
“You know that’s not the kind of relationship we have, right? I don’t ask you
to have sex with me in exchange for good grades. I’m not some sort of… high
school sugar daddy,” he said. Jungkook chuckled at the thought of sweet Mr. Kim
secretly meeting up with a bunch of different students who need a better grade.
“You could be… boys and girl would be lining up to ride you,” he said. Seokjin
sighed again.
“No, they wouldn’t… Besides, I don’t care about any of them,” Seokjin said. He
wrapped his arms tighter around Jungkook’s waist. Jungkook looked up at Seokjin
with a certain little twinkle in his eye. He ran his finger along Seokjin’s
jaw.
“Seokjin… If I asked you to wait for me, would you say yes?” he asked, using
Seokjin name for the first time all day. Jungkook was only in his second year,
and he had another year and a half to go until he became a legal adult. Seokjin
knew that he was asking for him to wait until they were legal so that they
could be a real couple, not having to hide their relationship. A year and a
half was a long time to wait, but there was no one on this earth who was more
worth it.
“Of course I would say yes,” Seokjin answered. Jungkook gave him a soft smile.
“Seokjin… Will you wait for me?” he asked. Seokjin chuckled a little.
“Yes.”
