Summary
     Thanks to an inappropriate note, Nagisa and Karma are stuck with
     clean-up duty after class on Friday. Too bad they make more of a mess
     than a clean-up.
Notes
     KarmaxNagisa smut, what else can I say. I also wanted to gift this to
     Sciencefictioness-San as an apology as I've been a bit busy to read
     her stories.
See the end of the work for more notes
The sun was close to setting, casting shadows across the floor and desks of the
classroom. The school day was long over, all the students left ages ago to
return to their homes or whatever destination they had in mind. Except for two
students, Karma Akabane and Nagisa Shiota.
"Stupid octopus sensei" grumbled the fiery red head as he plopped himself down
onto the teachers' chair.
"Would you please stop complaining Karma-Kun" Nagisa looked over his shoulder,
pausing in cleaning a desk, the one in front of the teachers'. Karma just blew
out a breath, pouting as he crossed his arms. Nagisa returned to his previous
task and scrubbed the desk with vigour. Karma leaned his head against the chair
and spun the chair around lightly. When the chair slowed to a stop, he was
greeted with a pleasant sight. Nagisa was bent over the desk slightly,
unknownly sticking his ass out and giving the other male a nice view. "Karma-
Kun can you please at least help, it was your fault we're stuck in this
situation" the blue-haired male pouted as he scrubbed the desk, trying to get
out all the little pencil markings. Karma just grinned and folded his hands
behind his head, leaning back against the chair even more.
"Nah, I'm good. And it wasn't completely my fault either". Nagisa dropped the
wash cloth he had been using onto the desk and turned around to face the red
head, his arms crossed.
"Really Karma-kun? You were the one who kept passing me those-those
inappropriate notes!" Nagisa blushed as he recalled the events of why they were
stuck on clean-up duty that Friday evening. Koro-Sensei had been talking about
chemistry when Nagisa suddenly felt a tap touch his head. He had looked behind
to see who or what touched him, he saw Karma wave at him and point down towards
the blue-eyed male's feet. He had looked down and saw a crumpled up ball of
paper. Nagisa looked at the other suspiciously, then after checking to make
sure Koro-Sensei didn't notice, he pushed his pencil so it rolled off the desk
and onto the floor, near the crumpled up ball. He reached down, picking up his
pencil and the paper. He checked once more to see if Koro-Sensei had noticed,
it seemed he hadn't but one couldn't be too sure. He quietly uncrumpled the
paper and read it, his face going a bright red.
-Your ass looks great today ;)-
Nagisa whipped his head back around to Karma, who just grinned and winked,
making the blue-haired male blush even more. Then out of nowhere Koro-Sensei
was in front of Nagisa, picking the note out from Nagisa's small hands. After
reading the note, Koro-Sensei turned pink.
"Nagisa and Karma, your both to stay here after class and clean all the desks"
he declared then returned to teaching. Nagisa's face a light shade of pink and
Karma pouting throughout the rest of the lesson. Nagisa shook his head at the
memory.
"Hey, if you had just read it without getting all flustered, we would've gotten
away with it" Karma drawled out, the chair turning slightly to the right. He
stared at Nagisa with hooded eyes "I also would've been able to take you home
and really appreciate that delectable ass". The smaller male blushed a bright
red, he quickly turned back around. Picking up the cloth he resumed cleaning,
his movements frantic almost.
"M-must you be so vulgar!?" Nagisa exclaimed. Karma only grinned in response.
He stood up and and silently walked up behind the embarrassed boy. He leaned in
and kissed his ear, causing the other to jump in surprise.
"But you like it when I'm vulgar, you love me talking dirty to you" he
whispered into the smaller male's ear, licking and lightly nipping at the lobe.
"K-Karma-kun!"
"Ssshh, lets stop cleaning Nagisa, lets do something else" he took the wash
cloth out of the other's hand tossed it over his shoulder and onto the floor.
One hand went around the other's slim waist, the other going up and spread
across Nagisa's chest.
"K-k-karma-kun we're at school! W-we c-Aahh!" he cut himself off with a loud,
surprised moan. The red-haired male having sunken his teeth in softly into
Nagisa's neck and sucking. A bright mark left in place as he lifted his head.
He kissed his ear and blew into it.
"It's ok Nagisa-kun, we're the only ones here. And since I couldn't take you
home, here will have to do". He peppered kisses, licks and nips on his lover's
smooth, pale neck. He began to grind against the pinned male's ass, the hand
placed at Nagisa's waist moving lower and groping him through his pants. Nagisa
threw his head nack with a loud cry, his right hand reaching up and lightly
pulling at Karma's hair, the other going to the hand groping him.
"Ah! Karma! nnnhhh!"
The red head chuckled softly, he licked a long stripe up the length of the
blue-haired boy's neck, his grinding becoming faster. Nagisa pushed his ass out
back against his lover's grinding, feeling the growing bulge forming there. He
cried out as his forming erection was roughly groped, his hips snapping
forward. Karma began to unbutton the other's vest with his free hand, quickly
slipping the item off with Nagisa's help of moving his arms. He continued
sucking and marking his boyfriend's neck while began on removing the blue-
haired male's shirt. After all the buttons were unfastened and it hung loose,
his hand went and began pinching and pulling at a pink nipple.
"Aaannnhh! Karma more! nnggh" the smaller male cried out, his back arching, his
chest pushing towards the hand toying with his chest and his backside with his
lover's arousal. His hands scratched as he tried to find a hold on the desk.
Karma grunted out a deep moan at his lover's loud cries, moans and pleas. Both
of his hands went to Nagisa's belt and quickly unfastened it, slipping it off
his pants and off his waist. The buckle making a clank as it hit the ground and
joined the vest. He slowed his hips down, causing Nagisa to whine at the loss.
He slipped off his pants, ending them up in buching at Nagisa's feet. The
panting, small male kicked off his shoes along with his pants and socks, they
too joing the growing pile on the floor, along with Karma's jacket as he threw
it off. Leaving the smaller of the two only in his grey briefs.
His hand went to the blue-eyed male's hips, pulling him back onto his crotch.
His other hand going back to pulling playing with Nagisa's now red and erect
nipples. Moans continuosly spilled from Nagisa's lips, his hips moving to push
back against the red head.
"Fuck Nagisa, look at you. Panting and moaning, so fucking sexy" he said into
his boyfriend's ear, loving th shudder he felt rack the other's body. Nagisa
looked over his shoulder to face Karma, his face flushed, and his breathe
coming in pants and small whines. His eyes hooded and darkened with desire and
lust.
"Y-you have far too much clothing on Karma-Kun" he breathed out. He pressed his
ass out against his boyfriend's crotch with more pressure. "Far too much" he
licked his lips. The red head felt desire shoot throughout his whole body. He
all but nearly ripped his shirt off, luckly he didn't tear any buttons off in
his haste. His hands went to his belt, but a pair of smaller hands stopped his.
He looked up to see Nagisa falling to his knees, making quick work of undoing
the buckly and removing his belt. Karma gulped at the sight before him, Nagisa
on his knees only in his underwear, looking up at him as he undid his pants, a
small smile on his face. Nagisa lightly kissed and sucked at the other boy's
navel, enjoying the way the muscles quivered slightly. He pulled down the
other's pants, helping him out of his footwear and trousers. The two only left
in their grey and black briefs.
Nagisa smiled up to Karma, then licked his lover's arousal through his
underwear. Karma groaned and pulled the blue-haired boy closer to his crotch,
who began sucking and groping him. The red head rolled his head and shoulders,
eyes closed. He opened him and looked down. Nagisa had his eyes closed,
immensed in giving his partner pleasure. Karma moaned and pulled on his lover's
soft hair gently. It had surprised him the first time they became intimate, he
had found out that Nagisa's sexual lust was a lot like his bloodlust, but he
could barely contain it at times like these. He pulled his hair again, harder,
causing the other to look up at him. His eyes swimming with lust, knowing his
own mercury eyes reflected the same, if not more.
"Come on Nagisa, do it properly or maybe I'll just leave you here. Needy and
wanting" he smirked to the boy below him. Nagisa's eye narrowed softly, then he
grinned up to Karma. Within seconds the red-haired male's black briefs were
bunched at his feet and a hot mouth encased his erection. His hands tightened
their grip on Nagisa's hair as the other boy stroked and sucked his cock. Karma
moaned at the pleasure. "Shit, Nagisa fuck, nnggh". He moved his hips forward,
Nagisa easily taking more of him in his mouth. He pulled his hair again, and
Nagisa moaned around his cock. In turn Karma moaned loudly, then began to
thrust into his lover's wet, hot mouth. The smaller male just moaned and moaned
around his boyfriend's arousal, enjoying the way he hit the back of his throat.
He put his hands on the other's hip and stopped him from moving and looked up.
His lover was panting, face flushed, his red hair sticking to his forehead. He
could see the light layer of sweat accumulating on his toned body. He pulled of
his lover, while keeping eye contact he slowly licked the head of the other
male's cock. His tougne going back and forth slowly, tasting and swiping up the
precum with his small muscle.
Karma couldn't stand it anymore, with a loud groan he pulled the smaller male
off of him. With a surprised yelp from the other, he turned and pinned him
against the desk. He fell to his knees and spread Nagisa's leg wide. The blue-
haired male tried to glance over his shoulder, trying to see what his lover was
up to.
"Karma what are yo-Aaannnnhh!", he couldn't hold back his loud cry of pleasure
as he felt a hot, wet tongue lick at his entrance. Karma chuckled at his
boyfriend's reaction. He spread his lover out more, his tougne taking long
swipes to Nagisa's pink hole. "K-Karma what are you d-doing!? aaannh". The red
head pulled back slightly and smirked.
"Like I said before, I'm going to appreciate this delectable ass" he dived his
tongue into the other boy's entrance and sucked, his hands groping and
massaging his ass. Causing Nagisa to nearly collaspe onto the desk, continous
whines and cries leaving his slack open mouth. "And it's quite delicious" he
moaned as pulled back, then dived right back in. He groped and sucked harder,
his lover's grip on the desk turning his knuckles white. He suddenly slapped
Nagisa's ass, hard. Causing the other to jump in shock and pleasure.
"Aaahh! Again! nnnnghh again! More!"
Karma obeyed his boyfriend's command and smacked him again and again, his
tongue deep inside his lover. Not relenting even a second in his attack and
onslaught of pleasure he was bringing the smaller male. Nagisa couldn't stop
the moans and cries of his lover's name leaving his lips, he breathe coming in
quick pants. He thrust his hips back up against Karma's tongue, wanting more.
Karma pulled back with a loud pop, a string of spit still connecting him to his
boyfriend's entrance, before it broke. He stood up and wrapped an arm around
the panting male, the other going to Nagisa's lips. He nudged his lips with his
fingertips, Nagisa quickly leting them inside and greedily sucked and licked on
them. Karma leaned down to his ear.
"Mmmmh, I'm gonna fuck you so hard. Your just begging for it" he whispered, the
blue-haired boy moaning around his fingers in response. "You tasted so
delicious, I can't get enough of you. You love me, and my cock pounding into
you, don't you?" he pulled his saliva soaked fingers out of that wet heat of
Nagisa's mouth, the smaller male trying to bring them back. The red head
brought his fingers to lover's wet and slightly stretched hole, slipping in two
fingers.
"Aaaaahhhhnnnn! Mmmnn, m-more Karma! Ah! I want more!" Nagisa arched his back,
pushing back against Karma's fingers. Karma sucked at his neck, twisting his
fingers, stretching his lover.
"Answer me first" he pulled Nagisa's hair, his head pulled back. "You love my
cock pounding into you don't you?" he growled out, he angled his fingers and
thrusted them into Nagisa, hard and brutal.
"Aaaaahhh! Fuck! Fuck! Yes! Yes yes! I love it! I love your cock! I love you
pounding and fucking me! Yes! Aaannnhh!" Nagisa cried out as his prostate was
harshly stabbed. "I love it! I love it! I love it! Nnnnggh! Fuck! More! I want
more! Give me more! Aaaaannnn!"
Karma let out a harsh breath at his lover's words, his cock throbbing. He added
a third finger, thrusting them into Nagisa's prostate. He licked his lovers ear
and bite the lobe.
"Thats right, beg for me Nagisa. Beg me to fuck you"
"Aaahh! Please! Please please please! Fuck me! Karma fuck me please!" Nagissa
begged, tears in his eyes. Karma pulled his fingers out and shoved inside his
lover quickly. Nagisa cried out and fell onto the desk, his hands scrabbling to
find purchase. Karma immediately began to thrust and pound into the smaller
male, his fingers no doubtly leaving bruises on his plae hips.
"I'm gonna fuck you so good. You love this, you love me fucking you. I'm the
only allowed tp touch like this, to fuck you, to love you!". Nagisa whined
loudly at his lover's words, pushing his hips in time with the red head.
"Yes! Yes! I'm yours! I'm yours! I love you fucking me! It feels so good! Yes!
Fuck! I love you! I love you! I love you!"
Karma leaned down and laid his chest down against Nagisa's back, he pulled
Nagisa's face towards him and kissed him deeply, their tongues twining and
searching each others' mouths. He pulled back, they were panting harsly,
flushed. He angled his hips slightly and kept up his rough pounding. Loud
continous moans and cries flew out of Nagisa's mouth. Karma moaned loudly and
sloppily sucked, kissed and licked at the back of Nagisa's neck, his hands
moving up and down his sides.
"Fuck, I love your body Nagisa. Your so sexy, so fucking sexy. You turn me on
so much". His hands groped Nagisa's ass, before moving back up. "God, I love
your ass too, so fucking soft and enticing and smooth". He turned Nagisa over
onto his back, still deep inside him. The smaller male swung his arms around
Karma's neck and held him close as the red kept pouding and pouding into him.
Leaving him a moaning, writhing mess. Karma licked and sucked at his lover's
collar bone, leaving more marks in his wake, then sliding down and sucking one
of his nipples into mouth. Biting, sucking and toying with it. One hand
pinching and pulled the other harshly. Nagisa arched up into his boyfriend's
touch, one of his hands griping wild, red locks.
"Ah! Ah! Aaah! Ah! I-I-I'm cumming! Annnnnhhhhaaaa! Karma!" he screamed out as
he came, all over his chest. Some even splashing onto Karma. The red head
groaned as the tight heat wrapped around him constricted further around him. He
moaned into his lover's neck, his thrusts becoming eractic. Moments later with
a cry of his lover's name, he came deep inside Nagisa. The blue-haired male
moaned at the feeling of his partner cumming inside him. Karma panted, his arms
shaking as he tried to keep himself up and not crush the other male.
As they slowly regained their breath, the two smiled warmly at each other.
Meeting a soft kiss, light moans leaving the two. As they broke apart, the red
head pulled out slowly. He quickly retrieved a wash cloth and began to clean
his lover, his composure returning. Nagisa just stayed where he was, enjoying
the feeling and love as Karma cleaned him. He then cleaning himself and
dressed, the blue-eyed male still laying on the desk. He smirked and kissed his
lovers softly, who responded in kind. Karma helped Nagisa dress and tidy up his
appearnace as best he could. The blue-haired boy sat back as Karma cleaned up
around them. When he was done he stood in front of his smaller boyfriend.
Nagisa smiled at him and dragged him down into another kiss, his tongue sliding
into his mouth. Karma pulled back with a smile, he gently caressed his lover's
face.
"I'm taking you home, and I'm going to make love to you" he spoke softly,
looking into soft blue eyes. Nagisa closed his eyes and leaned into the taller
boy's touch. He looked up, his eyes half lidded.
"I would like that very much Karma-kun" he breath out. They both retrieved
their bags and left the school, hand in hand as they made their way to Karma's
house.
