Despite what she ever would've guessed when she first met him, this is a familiar sight by now. Kokichi is still asleep, though he says he doesn't usually sleep in around anyone else and Miu isn't entirely sure what to make of that, other than that maybe he just feels safe around her and isn't willing to say that directly. As heartwarming as that assumption is, she still wishes he'd hurry up and wake up. Kiibo is most likely already 'awake' as always, even though she's certain she never gave him a fast charge feature. That's just how he is, forever the sole early bird of the three. But now she's stuck watching their extreme night owl other boyfriend sleep, a mess of dark purple hair tossed around his pale face from how chaotic he is even while he's sleeping, and one arm having wrapped around her at some point. Not that she couldn't do something about that, Kokichi isn't very strong and much less a heavy sleeper. She's just even less willing to admit he's cute like this (and in general) than he is to admit her presence is comforting while he's asleep. Miu isn't really that unwilling to let him rest a bit longer.
That is, until she catches one of his eyes cracked open for a moment, quickly snapping shut again as soon as he can tell she noticed.
"Hey! I saw that. Rise and shine, smartass, I've got better shit to do."
Kokichi whines, rubbing his eyes and stretching dramatically. "Ughhh, what's with all the yelling? Couldn't you see I was sleeping?"
"Yeah, I sure could. I had an excellent view of you faking it." Miu rolls her eyes, only to return them to direct contact with the big violet ones that are finally open all the way and fluttering the long black lashes that frame them. She tries not to react, but she can feel the color of her own face betraying her.
"Aww, what's wrong?" Kokichi snuggles against Miu tightly, playing up the cute factor for all it's worth until he gets the satisfaction of her admitting she likes it.
"You. You're wrong for this." She unfortunately can't contain her laughter when Kokichi immediately starts up a fit of giggles at that response. "Knock it off! You've said it yourself, you're pure fucking evil. I'm not falling for this."
"But you already fell for meeee…" he teases, looking up at her again with the most angelic expression known to man. "Even knowing I'm a soulless abomination Satan himself lives in fear of…"
Miu rolls her eyes again. "Whatever, edgelord. Get up, Kiibs is probably waiting for us."
"And?" The innocent act finally stops, and Kokichi's voice deepens instantly. "What if I want you to myself for a bit?"
The change in tone makes Miu involuntarily shiver. "S-so that's what this was about."
"Mm." Not bothering to deny it, Kokichi doesn't answer at all, shutting her up with a kiss and a shove to the shoulders. That doesn't actually have any effect, but Miu is more than happy to play along, rolling onto her back obediently so he can get on top. Being as scrawny as he is, Kokichi never wastes time and energy hovering over her, rather laying right down and leaving not a single gap between their bodies. It's his only hope of physically pinning her down, not that he needs to. The air of dominance he carries when he wants to may as well make him Miu's wet dream sleep paralysis demon.
Once he starts grinding on her, though, she's done being amused. "Stop fucking around and get on with it," Miu grumbles. She's quickly shut up with a rough hair pull, replacing her big talk with a pathetic whimper.
"Watch your mouth," Kokichi replies far too calmly, letting go of the handful of blonde only to take his sweet time pushing up the old t-shirt Miu slept in, making no less of a big deal out of tugging her panties off, pretending he's above even looking at each part of her he undresses. It drives her crazy how humiliating that is, even knowing damn well he actually is and always does.
"Y-yes sir," she belatedly replies, biting her lip so hard she's liable to draw blood before Kokichi smacks her mouth lightly.
"No hurting yourself. That's my job." True to his word for once, he lands a rough bite just below Miu's collarbone that's sure to at least leave a very nasty mark if not break the skin, and she practically wails.
"Please. Please just do something."
"Huh? I'm doing lots of things." As always, Kokichi returns to the innocent act at the worst possible time.
"You know what I mean!"
"No idea." An absolutely shit-eating grin takes over Kokichi's face, clearly planning on making Miu say exactly what she wants word for word, and she hates how much she loves doing exactly that.
"Just fuck me already!" she yells with hardly any hesitation.
"Who are you even talking to?" Kokichi's voice reads boredom, in contrast to the frantic way he's taking his pajama pants off and finding a comfy spot between Miu's legs. She's frustrated nearly to the point of tears, realizing what it is she needs to say.
"Kokichi, please!"
"That's more like it." With one final satisfied chuckle, Kokichi lines up their positions perfectly…
.. and rather than having the decency to take his time now of all points in the process, he slams into her all at once.
Miu screams. "Fuck!" She actually does tear up now, fingers curling into the sheets. Despite that having been painful as hell for her (in a way they both fucking love), at least Kokichi isn't big enough to cause any actual damage doing that. But Miu knows if she says so at a time like this, she's only going to deal with significantly worse. "K-keep going. Keep being rough with me."
Kokichi doesn't answer, just setting an immediately merciless pace. The sound of skin on skin is only overpowered by how vocally loud they're both being, and both are trying not to add mood-killing laughter to the mix of noises knowing there's no way in hell Kiibo doesn't hear them downstairs. "I… didn't even want… to start my day like this, y'know," Kokichi growls out between heavy breathing and moans that sound anything like someone who isn't enjoying himself. "I don't live... on a fucking farm." He grabs at Miu's breasts roughly, eliciting more cries. "I shouldn't have to get up early to milk cows."
She wants to call him on his bullshit, knowing damn well he's loving every second of this and his relentless degradation is nothing but proof of that. But Miu's not exactly one to complain about having her biggest kink used against her when having it used against her is the kink. She can't even manage a response, just blubbering between moans and clinging to Kokichi for dear life as the sadistic little bastard does what he does best.
There's significantly less talking past that point, but that means anything but them being quieter. Miu's moans start escalating first, and she cries like the world is ending when Kokichi's response to that is to slow down. "Did I say you could cum? God, you're needy," he says flatly, though he isn't keeping the shaking out of his own voice enough to be convincing.
"Kokichi!" Miu whines, pleading up at him with her eyes.
"Nope." With that, he not only picks the pace back up, but takes one hand off her chest to put it between her legs instead, rubbing her clit in time with his thrusts. He knows exactly what he's doing. "No cumming."
Miu is a total mess now, barely able to manage something that sounds like a garbled attempt at, "I can't-" before she disobeys the obviously impossible command, sobbing in relief through her moans when Kokichi immediately follows her over the edge with an infuriatingly adorable whine, clearly having had no plans of denying her in the first place.
Pulling out is the first thing Kokichi has done gently this whole time, and he promptly collapses his entire weight on top of Miu while they both catch their breath. The afterglow doesn't last long, as neither of them get to say a single word before they hear Kiibo shouting, "If you're done having fun without me, breakfast is getting cold!" from downstairs, and both dissolve into cackling.
"Maybe if you were willing to be this kinky, babe!" Miu yells back.
"Do robots even have kinks?!" Kokichi piles on, sitting up and trying to find his pants, Miu wincing through her laughter as she does the same.
