Summary
     After Mirai's return to the world, things have finally settled back
     into place... except for some awkward tension between her and Akihito
     (Disregards movie)
Notes
     This is honestly just some self-indulgent bullshit, but there are
     about 4 other NSFW fics of this pairing on the internet and I really
     need this right now.
     Also, those fanfics have all gotten a few things right, so forgive me
     for doing some of the same, I have a passion for shy Mirai and rough
     Akihito.
See the end of the work for more notes
It had been about two months since Akihito Kanbara had returned to that school
roof to find Mirai Kuriyama standing at the fence, overlooking the street
below. They had walked back to her apartment in near silence, fingers
intertwined, and he had left her there. Now, he was paying for it.
The pink-haired girl had barely spoken to him since, outside of the standard
interactions.
"Kuriyama-san," he whined playfully, and she turned her head away from him,
crossing her arms in an adorable pout. The two had stopped at a restaurant
after school to satiate Mirai's constant hunger, and had tucked themselves away
in a booth near the back corner.
"You just left me there, without even a hug, without anything," she said.
"Well, yeah, because-"
"You left me there without food!" she shoved an accusatory finger in his face.
This was new.
"Wait, what?" Akihito blinked.
"You walked me to my apartment, and I was feeling a little scared, so I didn't
say anything, because it was such a strange experience, and then you left,
senpai, and I hadn't had the opportunity to go shopping!"
"I... I'm sorry," the boy stared for a minute before bursting into laughter.
"What's so funny?" the Spirit Warrior asked, leaning forward and glaring. Her
closeness caused the boy to lean back and look away in embarrassment before he
could answer.
"Nothing it's just... I thought you were mad about something else, that's all.
Like... that I hadn't done something else, or... whatever. Anyway, I'll make it
up to you. I'll get you a bigger portion here, and then afterwards, we can stop
at the grocery store."
Realizing her own position, Mirai plopped back into her seat, and blushed
heavily, having been so close to her senpai, and nodded a little, kicking her
feet back and forth beneath the table.
What Akihito had thought was going to be a silent meal with little eye contact
turned out to be very pleasant, with the two teenagers making actual
conversation for the first time in quite a while. Akihito was able to recount
some of the events that had occurred after Mirai's disappearance, talking about
Hiromi's shenanigans, and the types of weather they had been having. It was
nice.
After they had eaten, and Akihito had paid, they set out for the store. Since
he had not specified a limit on how much he was willing to pay, Mirai took it
to mean that he did not care how much he meant to pay, and thus had him
maneuvering down every aisle to collect what she needed. Cereal, beans,
vegetables, instant rice, stove ramen, iron supplements, and a variety of other
items, piling the cart that she had forced on him nearly to the rim. It took
about 5 bags all together, but they managed to pack everything well enough to
carry them back to her apartment.
They got the bags inside, struggling to raise the heavier ones on to the
counter, and Akihito decided it was time to take his leave.
As he was at the door, he smiled back at Mirai, who was looking down and
shifting her weight from one foot to the other hesitantly.
"What's wrong?" he asked, shivering slightly in the cold winter air.
"It's nothing, really..." she said, "I'm just curious, what did you think I
wanted when you left last time, senpai?"
"Oh, well, um..." he blushed and looked away, fiddling with the bottom of his
jacket. "I just thought you were expecting something after that confession, or
whatever."
"Expecting what?" she looked up at him. Akihito knew he was playing a very
dangerous game, but he was backed into a corner, it seemed. Might as well take
his chances, and then run if things get too bad. Worst case scenario, she stabs
him again and he has to buy some new clothes.
"Like, expecting me to k-kiss you or something." The older teen could feel his
cheeks heating up at the comment, and he did everything to avoid looking at the
girl.
"Do... you... want to kiss me, senpai?"
The question caught him off guard. It was true, he was in love with her, and he
was pretty sure she was in love with him, too. But he hadn't thought too much
about how to act on those feelings. He had beat himself up over not kissing her
when he first saw her again, and had done it once more when he left her without
a single word at her apartment.
"I mean... sure, but it's not like I will or anything."
"Well, you might as well... before you go. It's... what guys do, right?"
Akihito returned his gaze to her and saw her face was bright pink, her glasses
sinking down the bridge of her nose.
In one quick motion, he lifted her chin and pushed her glasses back on her
face, staring into her glistening eyes before connecting his lips with hers.
Mirai's eyes went wide, and just like that, it was over.
"There," he said as he pulled away, "happy?"
The girl reached up to touch her lips, already missing the warm feeling pressed
against her mouth.
"Are you okay?" Akihito asked, and Mirai's face turned pink. He smirked and
leaned forward, kissing her again. This time, for longer, and her eyes closed
partway, savoring the feeling. She could feel his body get closer to hers, and
without thinking, she wrapped her arms around his neck. He tilted his head
slightly, as their heads bumped awkwardly, causing him to chuckle into the
kiss.
They broke away only for a moment before she pulled him in again, this time,
her mouth was parted slightly, and he opened his mouth as well, running his
tongue across her lip. Mirai's eyes flew open, but she did not break away, as
Akihito pulled her body flush against his, arms wrapped around her waist. As
their tongues wrapped around each other, the elder boy pushed her back inside,
kicking the door shut behind him. Through passionate kisses, he led her back to
the kitchen, where he pressed her against a wall, hand running over her
sweater.
"S-senpai!" she pulled back sharply, nearly hitting her head on the wall behind
her.
"Is that too much? I'm sorry, we were just moving so fast, and I lost control
of myself," he stammered, mentally kicking himself for trying to take his
actions so far.
"It's not that, it's just... are you sure you want to... with me?"
This was yet another question that caught him off guard. Why would he not want
to?
"Are you sure... I look like a normal person to you?"
There it was again, that question, always asking, always prying into the back
of his mind. Without answering, Akihito pulled her sweater off, tossing it onto
her, relatively clean, kitchen floor. Their lips clashed again as he dropped
his own jacket and began working at the buttons of her blouse. Mirai shivered
as he pushed down her arms, leaving her torso almost completely exposed. Her
bra was black, with a floral print that was similar to a vase Akihito had seen
at Ayaka's. There was a small piece of black lace that ran from the strap
across the cup to the center of the bra.
Mirai blushed heavily and refused to make eye contact, but Akihito couldn't
stop himself from watching her. He ran his hands over the fabric and her breath
hitched in the back of her throat.
"Kuriyama-san, could you, um..." he gestured to the article, which she realized
he was unable to remove, with her back pressed against the wall.
"How unpleasant..." she said under her breath as she reached behind herself and
unhooked the back, letting it fall down her arms. Mirai looked down at his
chest, with nothing else to look at, as he marveled at her chest. It was
definitely on the small side, A cup, maybe a B if she was lucky, but to
Akihito, they were the most beautiful breasts he had ever seen. Not that he had
seen too many. He had once seen Mitsuki's when he accidentally walked in on her
when spending time with Hiromi, and he had suffered the consequences for that.
But outside of dirty magazines, he had never seen any, and even then, none as
beautiful as Mirai's.
Akihito spent a minute running his hands over the soft skin, her voice
squeaking every time it ran over the raised part in the center, giving each one
a soft squeeze, massaging them between his hands.
"D-don't just play with them..." Mirai stammered out, and Akihito remembered
where he was.
"Sorry!" he said, leaning forward and kissing the top of one of her breasts. He
trailed down and across, raising to the peak and taking one nipple in his
mouth. Her voice came out again in a high-pitched squeal. The flesh was
surprisingly sweeter here, and he wasn't sure if that was because of the fabric
of the bra, or just a natural reaction in her physiology. Regardless, he worked
his lips, teeth, and tongue over the nub, resulting in some impressively high
sounds from the girl. He took his mouth off, and rubbed it with his thumb while
he went to work on the other one, sucking and nibbling at the small pink
protrusion, his lips covered in saliva.
"Ka-nbara-senpai-!" she squealed out. Akihito took his mouth off to kiss her,
turning the girl and moving her towards the counter. She didn't object, and
when her rear hit the ledge, she pressed her palms to he top, and he helped
lift her up onto it. Now, their mouths were roughly at the same level, allowing
hem to go at it more.
Akihito began pulling off his tie, and broke the kiss just long enough to drop
his vest, kissing her even more roughly as he unbuttoned his shirt and
deposited it to the ground. Their rough grinding and squirming knocked some of
the groceries down, but they ignored it, Akihito merely kicking it off to the
side, so as to not trip on it at any point later.
Mirai broke away from the kiss, her lips wet with saliva, and glasses askew,
and looked down, trying to figure out what was pressing so roughly against her.
Was it Akihito's knee? Her face went flush when she noticed just how tight his
pants were. She knew the general way that a man's penis got hard, but she
wasn't too sure of the specifics.
"O-oh, um... did you... want to do... something with it, or...?" he asked,
quite embarrassed, though he secretly had hopes.
"No way!" she blushed heavily and shook her head violently, almost causing her
glasses to fall from her face. "That's so unpleasant!"
An idea sprang into his mind, and he kissed her again, flipping up Mirai's
skirt and pulling her tights down from her hips. The girl covered her underwear
with her hand and pressed her thighs together.
"Wh-wh-what are you doing?" she gasped out as he dropped her dark tights at his
feet.
"Is this also unpleasant?" he smirked up at her, grabbing the panties at her
hips and slowly sliding them down. She gave in without much effort, and he
could see that they were pink, with a small bow on the front. Very cute, but he
would have to marvel at it later. In front of him, barely covered by a hand,
was a glistening flower. He took her wrist and slowly moved it away, exposing
her most sacred place. It was already dripping wet, with fluids running down
her upper thighs. He could tell she took care of herself, as her smell wasn't
too heavy, but intoxicating none the less. It was a lewd smell, and if it
weren't for this situation, he might have found himself a little repulsed. But
for some reason, that he could not explain, he was drawn to it, like a moth to
flame.
Mirai had taken care not to let her pubic hair grow out of control. It was
partially shaven, and the rest trimmed, and it did not cover her entire pubic
region, like he was sure some girls did. It was more centralized, and smaller,
leaving just enough to look appealing without reminding him of some elderly
housewife.
Akihito leaned in, running his tongue across the shimmering pink of her sex.
Her hand immediately flew up to her mouth to keep from shouting at the
sensation. Obviously, he figured, he was doing something right. He ran his
tongue over the surface, up and down, swirling it in circles. He felt her body
tremble in front of him, Mirai's juices dripping onto his lips. He opened his
mouth, sucking in some of the organ, and bringing her body to tense up. He
repeated this a few times before letting his tongue explore once more. He found
something strange. What almost felt like some sort of bead. He licked it a few
times, and didn't notice the change in her body. He pulled his mouth away, and
began rubbing at it, more to keep track of its location than anything else.
"Kuriyama-san, what's this, some kind of battle injury?" he asked, readjusting
himself before looking down at her, noticing her eyes rolling back into her
head. He stopped rubbing almost immediately, and pulled his hand away, but
Mirai began shaking her head violently.
"Please, don't stop, please don't stop," she panted out, and it dawned on him
that what he had found must have been her clitoris. He smirked and sank back
down between her legs, licking the hard spot again and again, pressing his
tongue against it, pulling it into his mouth when he could, all to make her
whole body shiver with ecstasy.
Mirai's hips bucked up into his face, and he wrapped his arms around her
thighs, riding out her orgasm as he continued to eat her. When her hips stopped
moving, and her legs remained shaking, Akihito came up for air, and kissed,
Mirai deeply, their tongues wrapping together, then she pushed him away.
"Is... that what I taste like?" Mirai covered her face. "I'm so sorry, it's not
good at all."
"H-hey, no, it... it tasted so good." Akihito pulled her hands from her face
and kissed her again. "Kuriyama-san," he groaned, "I don't know if I can take
it anymore... can I please... do it with you? Make love to you?"
Make love. Those two words, two syllables, held so much power and emotion.
Mirai adjusted her glasses, which had practically been flung off of her face,
and nodded.
Akihito fumbled with his belt buckle and dropped his pants, followed soon after
by his green boxer briefs, and allowed her to marvel at his length, which had a
slight upward curve. He was proud of himself to making sure his own pubic
region was pretty well maintained. In fact, below his eyes, his body was very
well taken care of in terms of hair.
"Wait, w-we don't have a condom," he realized, murmuring to himself. He hadn't
expected this to happen, why would he have one? Damn, Hiromi was right, the one
time he suggested to keep a condom in his wallet at all times, but he never
considered it to be real advice.
"It's okay," Mirai's voice was soft, and comforting, "I trust you, senpai."
Akihito nodded, and moved closer, sliding his member up and down between her
lips, the girl braced herself against the counter. He got the tip drenched in
her juice, before finally pushing it against the entrance. She clenched her
fists as the tip of his cock slid inside of her. The boy rocked his hips ever
so slightly, pushing it a little deeper in, and then stopped.
"Are you okay? Does it hurt?" he asked, his voice heavy with concern. If she
said yes, he was very willing to pull out, put his clothes back on and go home
to masturbate, if that's what she wanted. But she smiled and shook her head.
"A little uncomfortable... I've never done anythin-anything like this before."
Mirai's legs trembled as Akihito slowly pumped a little, pushing in deeper with
each motion of his hips, until finally, his body rested against hers again.
"Kuriyama-san, it feels so warm inside of you... it's so good."
"It feels good for me, too, senpai," the girl leaned back, her breath heavy,
and he pulled back before sliding back in. He repeated the motion a few more
times, letting her get used to his girth inside of her body, but before long,
she was rocking her hips, too, trying to feel him more. Taking this as a hint,
Akihito began sliding back and forth harder and faster, and the two soon picked
up a comfortable rhythm. Their bodies clashed, the sound of skin slapping on
skin and the slick sounds of his cock sliding in and out of her, along with
their moans of each others' names filled the kitchen with more sound than it
had heard in a long time.
Their bodies pressed together, and Mirai wrapped her legs around Akihito's
waist, pulling him closer as she leaned as far back as she could. Akihito
braced himself against the counter, thrusting harder into her as the Spirit
Warrior began screaming in pleasure, her whole body shaking. So soon after her
orgasm, she could feel a second one building, the warm feeling pooling in her
stomach.
"Senpai, I'm... I'm gonna-!" Mirai screamed as she reached her second orgasm,
her vaginal walls clenching down on Akihito. He leaned down to kiss her, and
then pulled himself back, his member hitting the open air as it spurted semen
on Mirai's chest, stomach and upturned skirt.
The half-youmu boy helped the girl down from the counter, and supported her as
her legs shook, guiding her to her bedroom, he laid Mirai down on the mattress,
leaning over her and kissing her again.
"Senpai," she mumbled, while Akihito brushed her messy hair from her face, "I
love you, too."
