The Inner Workings of a Chibi.
Headcanon: in which Naoto wishes that she had looked up the criteria of sleepovers

Inspired by this fanart here by the lovely krisrix and because I felt like writing something a bit naughty (what can I say, sometimes the OTP wants some action).

“So how are you two going to have sex?”

This is not the type of conversation Naoto Shirogane had in mind when Rise suggested that all of the girls get together “without the boys” for one evening.  Perhaps if she had researched the topic of “slumber parties” before coming over… but she’s been trying to not research social matters as much.  According to Rise, that’s totally lame and she needs to actually go out and experience the world, not read about it. 

However, Rise failed to mention that “experience” meant talking about her relations with one Kanji Tatsumi.

Naoto tells herself not to blush and stutter, “W-w-what do you mean?!”  Not only does she fail, but she ends up shouting, too.  She’s been around Kanji for much too long.

“Well… Kanji is a big guy, ya know.  How are you going to have sex?”  Rise is sprawled out on her bed next to Naoto, poking her in the arm as she asks how are you two going to have sex?  

“That’s a valid question,” this, surprisingly – or unsurprisingly – comes from Yukiko.  She’s sitting on the floor next to Chie, all elegance and grace as she sips her canned beverage through a straw.  The complete ideal image of a lady, “I mean… it might not fit inside if it-”

“Yukiko!”  Thank goodness Chie seems to have some- “Don’t tell her that it’ll scare her!  They can make it work!” … nevermind.  The girl in the green jacket takes a rather determined handful of popcorn, pumping her fist in the air.  At least Naoto has a cheering squad in her corner?

“F-first of all, how do any of you know… w-w-what size…”

“He’s so tall, he has to be a big guy!”  

“That is not necessarily true…”

“Yukiko, how do you… wait, have you seen it?!”

“N-no!”  Then, “Well…”

Naoto’s eyes widen and she stares at Yukiko, “Y-you… when did you…”  Don’t be jealous, don’t be jealous, this was probably before she was even in town…

Yukiko seems to sense her worry and smiles, “Don’t worry, Naoto-kun.  We were much, much younger at the time.  And, well… it wasn’t that big…”

“Yukiko, is this back when you were kids?  That’s not really a fair comparison if he was six at the time.”

Yukiko snorts, “I-I suppose not.  It has to have grown by now, right?”  Then she starts laughing, “God, but what if it hasn’t?!”  And now she’s curled up on the floor, arms wrapped around herself as she laughs.

As Yukiko laughs to herself Rise speaks again, “I think it has.  I mean, remember the beach guys?  He wore a speedo.”

“Oh yeah…” Chie chuckles nervously, “And… d-don’t kill me for saying this, Naoto-kun, but you’re a lucky girl.”

Sigh.  Yet another trip that Naoto missed out on, but she decides to take Chie’s comment as a compliment, “Thank you.”  She knows that she’s lucky, Kanji is a rather nice young man… then she blushes when she realizes that Chie meant lucky in a completely sexual manner.

Now that Yukiko has stopped laughing she manages to speak again, “Well… I mean… isn’t he supposed to loosen you up?  Foreplay and all that?  That should help it fit, right?”

“Seriously Yukiko, how do you know so much?”

“Well…” she gives Chie and Rise a sheepish look, “I… sort of… with Seta-san…”

“W-what?!”  

“With senpai?!”  Rise sniffles, “But… but I was planning on…”

“Oh, you still can.  We’re not together, not like that.  It was just one time, honest.”

Naoto almost comments on how relieved Chie looks but she decides not to.  Chie gives her a grateful smile.

“Besides, didn’t you and Hanamura-kun sleep together, Chie?”

At this statement Chie nearly chokes on the popcorn she’s just stuffed in her mouth.  Yukiko is quick to pat her back until she’s forced to jump away, Chie whirling around to face her and scream, “W-w-what?!  Yukiko, what the hell?!  You think the two of us-?”

“Honestly, I did too senpai,” Rise says.  She leans over the side of the bed to grab some popcorn for herself.

“Did you?”  Naoto asks.

“… j-just once, o.k.?!  Jeez!  I-i-it just sort of happened!”

“Is it going to happen again?”  Yukiko asks.  Both Naoto and Rise smile a little when they hear the small hint of concern in Yukiko’s voice.

“What?!  A-absolutely not!  N-n-not that it was bad or anything, just… h-he’s my friend, and I-”  

“I see,” and Yukiko takes another sip of her drink, quietly smiling around her straw.

“Now, back to the topic at hand.  Kanji and Naoto sleeping together.”

Damnit.  Naoto had hoped that they had forgotten about that.

“Right,” Yukiko says, “As I was saying, foreplay should-”

“I-I am aware of what foreplay is.  Kanji and I have-” crap, said too much.

“What?!  When?”  And now Rise is poking her again, “Tell us!”

“Um… a couple of times…”

All three girls look at her, waiting for details.  Naoto decides that all of them need to find some other way to explore their sexual desires instead of living vicariously through her.  Perhaps she should tell senpai to devour Rise, and shove Chie and Yukiko into a closet, “… just… it… i-it was fine…”

“Fine?”

“Just fine, Naoto-kun?”

“Come on!”

“It was quite nice, actually.  He is… good at…” don’t blush don’t blush – damnit, “So… w-we should be fine, yes?”

The next evening has Kanji and Naoto sitting on her bed.  Kanji is down to a tank top and boxers – the furthest he’s ever gotten in their fooling around – and Naoto is down to her panties.  They haven’t stopped kissing and it’s leaving a wonderful flutter of butterflies in her stomach.  She can’t help but think that yes, Kanji is quite good at this, remembering the previous night’s conversation.  This becomes much more apparent when his hand gently urges her legs apart, fingers brushing against her already moist underwear.  

This part they have done before, several times actually.  She hadn’t gone into detail last night – because it’s nobody’s business – but Kanji is more than just good at this part.  It’s what happens when you have a crush on someone for months, he says.  He’s got all of these desires towards her that had been building up since day one, and now that he has her he’s anxious to experience every one of them.  This means that he’s constantly touching her, constantly kissing her.  He’s always satisfied with teasing her, feeling her, commenting on how fucking beautiful she is as he touches her in all the right ways.  Because of him she’s learned all of the wonders of squeaking, moaning, and whimpering his name.  It’s completely embarrassing, how he turns her into this sexual being, but she can’t deny how amazingly sexy she feels when she’s in bed with him.

But tonight she wants to take the next step.

So it takes all of her willpower to tell Kanji to not get down on his knees.  He looks a bit disappointed – it is one of his favorite things, he discovered a couple of weeks ago.  A more naughty part of her brain whispers let him play for a few minutes because lord, the things Kanji Tatsumi does with his ton-

No, just no.  Not if she’s actually going to do this.

“I think we should go further than that tonight.”

“Further… o-oh, oh!  You want…”

Naoto nods, “If that is alright with-”

Never before has she seen anyone undress so quickly.  The tank top and boxers are tossed to the floor, Kanji eagerly standing in front of her.  It’s here that she lets her eyes wander down in-between his legs.

Rise was wrong, absolutely wrong.  

He’s much bigger than she had assumed he would be.

Naoto’s mind is working as fast as it can as Kanji leans down to slide off her panties.  How is he going to… is it even possible for him to… oh goodness he’s right above her, looking down at her, and she can feel him rubbing himself against her.

This isn’t going to work.

This is not going to work.

This is-

“A-ah!”

He rubs against something, very slowly.  Her legs are shaking, spreading further apart, her eyes squeezed shut as her body takes complete control.  She’s moving against him, trying to feel - “A-aaaaaah” that’s good, yes that’s very - “aaaaaah

“I-is this o.k.?  I-is this-”

“Y-yes.  It… oh gods, it…” she wants to stop talking, wants to stop embarrassing herself but-

“Shit, you’re so fucking beautiful.”

And there’s that feeling again, of being the sexiest being alive.

She can feel her toes curling, her legs lifting in the air as he starts to move against her more.  Slick wetness against his hard shaft, both of them panting together, shaking, “Fuck,” he whispers, “F-fuck Naoto,” because she feels so good, so damn good.  At some point his hand has made it around her wrist, lightly pinning her to the sheets.  At some point her other hand has reached back to grab onto the pillow.  

“K-Kanji… Kanji, I-I want…”

“Are you sure?”  Always have to be a gentleman with a woman like Naoto, that’s the proper thing to do.  But it’s hard – literally – and he really, really really hopes she says-

“Yes, I-”

That’s all he needs to hear.  

And it’s nice to know that Chie-senpai had been right.  Unfortunately, so lost in the moment, Naoto actually blurts that very thought out.  Kanji blinks down at Naoto, no longer moving inside of her.  Before he can ask what he means he can feel her tightening around him, these tiny little noises slipping past her lips, a clear sign that she wants more.  

Kanji Tatsumi isn’t known for his intelligence, but he does know that if he has a choice between sleeping with Naoto Shirogane or asking her what Chie-senpai had been right about, it’s definitely best to pick door number one.  

Not like he doesn’t have dirt on Chie-senpai, anyway.  Yosuke-senpai talks a whole lot when they get together at senpai’s house.  Speaking of which, it’s good to know that Yosuke-senpai had been absolutely right at their get together last night – not that he’ll ever tell him that.
