Work Text:
Kokichi sucked in a breath as the first loops were made around his wrists.
He was naked, laid out flat on his stomach. He couldn’t see what Korekiyo was doing, but if the angle his arms were being held at were any indication, he was being fastened into a captive tie.
“Ugh, come on,” he complained, as his partner connected his bound wrists to the belt of rope around his waist with a simple, taut column. “What is this beginner shit? I could get out of this in my sleep.”
To demonstrate his point, he began wriggling around, grasping at the cords he could reach.
He froze when a cold, steady hand landed on the nape of his neck and squeezed.
“I have no doubt in your ability to escape, dear thing,” Korekiyo said, a light, amused tone in their voice. “But I am afraid I shall have to punish you, if you continue to misbehave.”
The threat only phased him for a moment.
“Deal!” Kokichi said cheerily, pulling against his restraints again with twice as much vigor.
This time when Korekiyo corrected him, it was with a hand in his hair.
“Two infractions thus far, Kokichi,” Korekiyo tutted, twisting their fistful of his hair.
Kokichi gasped out, breath stuttering. The sound betrayed just how much he enjoyed the feeling.
“I chose this tie because, with what I have planned, you are going to want a little bit of movement,” they elaborated. “If I wanted you immobile, you know very well I could make you immobile.”
“Well, if —“ Kokichi started to complain again, but Korekiyo just used the leverage on his head to press his face into the mattress.
“Three,” Korekiyo counted. “My goodness. If I didn’t know any better, I would think you wanted me to punish you.”
Kokichi tried to say something but the mattress completely muffled his voice. His hands closed into fists and opened again.
“Hm? What’s that, Kokichi?” Korekiyo asked, cruelty twisting into their tone, their smile. “You know I can’t understand you when you mumble.”
They released his hair. He lifted his head slowly. “You’re so fucking mean,” Kokichi whined, turning to address Korekiyo, tears building in his eyes. His lip quivered just a tad too slow for it to be sincere.
Korekiyo chuckled, low, the sound buzzing out of their chest. “Oh, I’m mean. I see,” they said, sweeping their hair into a low ponytail. “I’m mean for doing exactly what you asked me to?”
Kokichi rolled his eyes. “I told you to tie me up, not put me in this little chickenshit over-arm hold,” he argued.
Korekiyo was quiet for a moment, an eyebrow quirked up. “I have decided to start counting swears. Which I believe brings you to four.”
“Four what?” Kokichi asked. “Four spanks? Geez. Like I said, I’m not a fuckin’ beginner—“
Korekiyo cut him off this time by tapping the plug in his ass a couple of times. His voice broke away into a small whine.
“That was five,” Korekiyo noted. “Did that feel nice, Kokichi?”
Kokichi’s blood was rushing a lot of different places, but a decent amount colored his face red. “Mm-hmm…” He pressed his ass back against Korekiyo’s hand, chasing the light pleasure.
Korekiyo pinched the edges of the plug and turned it slightly. “See? I can play nice.”
Then, without waiting a beat, they slapped him across his ass. “Color?” They added.
“Green,” Kokichi groaned, far from pained, mostly just shocked. “Fuck, shit…”
“That’s seven,” Korekiyo said, laying out a couple more on the backs of Kokichi’s thighs. “We have got to do something about your manners, darling.”
Kokichi tried to scoff, but his breath hitched after another hit. “Will you give me more if I just swear a bunch?”
Korekiyo said nothing.
Without giving it any more thought, Kokichi went into a string of, “fuck, fuck, fuck,”s, that became more and more loud and broken-up as Korekiyo continued to spank him.
Kokichi only stopped the stream of curses when Korekiyo placed a light hit directly over the plug. “Oh, ohh…” he whimpered, and this time, when a couple tears gathered in his eyes, they weren’t so phony. He felt his cock ache, pinned tight against the mattress.
“Tell me, Kokichi, are we at fifteen or sixteen?” Korekiyo asked, with that same slightly charmed voice they had started with.
“Um,” Kokichi said, breathless. “Sixteen.”
Korekiyo laughed again, the sound a little higher in their register. “Good boy,” they praised, craning down to plant a kiss on Kokichi’s shoulder.
This made Kokichi bite his lip again, trying to stave away a smile this time. “To make it up to you, we could call it twenty,” he suggested.
“Twenty,” Korekiyo repeated, borderline gleeful. “If you insist. Very good, Kokichi.” They paused, rubbing a gentle circle into his thigh. “These were merely to warm you up. You may choose what I’ll use now.”
A little thrill went down Kokichi’s spine, jostling his bound position. “Uh, the crop,” he said.
On Korekiyo’s silence, he added a little, “please?”
“Very well,” Korekiyo said, stepping away from the bed to retrieve their riding crop from the dresser. While they were over there, they grabbed some lubricant, too. “I cannot believe how polite you become once you get just a little bit of praise.”
Kokichi hummed, shifting around again, though not to get the rope off him, this time.
“Mmmhh…I like being good for you.”
When Korekiyo returned with the toy, Kokichi was rutting into the bed. They watched for a moment, shaking their head. “You say that just as you start behaving poorly again. Stop that.”
Kokichi whined, a mixed sound of desperation and compliance as he forced his hips still. “You didn’t tell me I couldn’t…” he refuted.
Korekiyo elected not to continue the argument. “Color, Kokichi? I have the crop now.”
Kokichi perked right back up, sticking his ass out, impatient. “Green! Green, green, green!”
Smirking, Korekiyo said, “Count for me, darling,” and began their barrage of hits over his behind and already trembling thighs.
Swat.
“One.”
Swat, swat.
“T-two, three.”
Swat, swat, swat…
“Ahh! F-four, five, six…”
Miraculously, Kokichi made it through all twenty hits without a single full swear. There were plenty of times his mouth would curl to make the word, but he’d force it away.
He was crying again, tears rolling down his cheeks like warm streams caught by the sheets. Through the last of his whimpers and his catching breaths, he murmured, “Th-thank you, Kiyo…”
Korekiyo ran their hands over the different marks and bruises-to be, nothing but proud of the work they’d done on him. “You’re welcome, dear. You did so well.”
They cracked the lube bottle open. “I’m going to touch you, now. Color?”
Kokichi squealed, just a small, anticipatory noise. “So green,” he sang through a sob.
“Good boy,” Korekiyo praised, pulling the plug out of him slowly. It was agonizing, especially after having taken some hits, but Kokichi didn’t have time to complain about the empty feeling. Korekiyo thrusted three wet fingers straight in, guided straight to that little bundle of nerves.
“Ohhh, holy sh…oh my god, Kiyo…” Kokichi whimpered, thrashing as his senses went from almost zero to a hundred. “Yes, yes, yes, yes,”
Korekiyo mourned the fact they hadn’t flipped him over to watch his face, but they were already knuckle deep and quite settled in a rhythm. “You may swear,” they granted, deciding not to be a monster.
Well, not yet.
As if he’d been holding the word in for years and years, Kokichi cried, “Fuck!”, which made Korekiyo grateful for the mattress again.
It wasn’t long before Kokichi was letting out the most delicious, high whines.
“I’m gonna…Kiyo, oh, god, Kiyo, I’m so close,” he babbled, lifting his head to make himself a little clearer. “Can I? Please? Please?”
Korekiyo hummed, considering his pleas for just a moment, before slipping their fingers out. “Sorry, darling. Your punishment begins now.”
Kokichi’s head whipped up, and jerked to try to meet Korekiyo’s gaze, but the pose restricted him from doing so. “Wh— huhh?” He asked, all wound-up and broken and confused, exactly as Kiyo wanted him to be.
“As punishment for misbehaving,” Korekiyo started, sickeningly smug, “I will edge you for every infraction. I believe we agreed on twenty?”
“Evil,” Kokichi hiccuped as yet another wave of tears filled his eyes. “You’re evil, Kiyo!”
Korekiyo couldn’t help but laugh, the sadistic part of their brain absolutely thriving off his reactions. Kokichi was beaten down and at their mercy, sharp bratty tongue dulled down.
It always felt like such an accomplishment to bring Kokichi to this state.
Still…the part of their brain that had to be responsible forced them to ask, “Color?”
Kokichi thought about it for a minute, trying to steady his breathing. “…green.”
Korekiyo rewarded that answer by slipping their fingers back in, creating a cycle.
A pleasurable but ultimately vicious, cruel cycle.
They fingered him right to the edge and denied him a second time, a third time, and every go-round he got louder, whinier, and more desperate, cursing and begging for it, but he had set his own punishment, so he was going to do his best to bear it.
That was the game, wasn’t it?
“Okay, o-okay, I can’t,” Kokichi said, eyes squeezed shut. He was on edge number twelve, and his whole body was convulsing, unable to still, unable to calm, and he, he — he couldn’t form any thoughts when Kiyo swiped their finger over his rim. “Ohhh, god, fuck, yellow, yellow yellow yellow —“
Korekiyo let their dominant character break away. “Understood,” they said, pulling away from him. They helped him move into a more comfortable position on his back, careful not to hit any of the bruising. “Breathe, love, breathe.”
“Breathing,” Kokichi gasped, near-hyperventilating at first, but slowly, slowly, his breath returned to him. “Oh, god…”
Korekiyo nodded, watching as the rising and falling of his chest became steady. “It’s okay,” they assured him. “I can untie you, and fetch you some water?”
Kokichi made some kind of small, involuntary noise. “Don’t go. Don’t go,” he pleaded. “Just give me a…I don’t think I can…”
Korekiyo frowned, not displeased, just lightly concerned. “Take your time.”
He did, letting himself just sit for a moment without speaking.
“I don’t want to stop,” Kokichi said at last. “I just — I’m getting too…if we keep going like that, I’m not gonna be able to stop myself, and I wanna be good.”
That admission broke Korekiyo’s heart a little bit. “Oh, Kokichi,” they whispered, voice going tender. “You’ve done wonderfully. I wished to find your limit, and if this is it, I am satisfied.”
That helped Kokichi’s face relax into a smile. His eyes were still puffy from the tears, and his face was completely red, and to Korekiyo, he was absolutely nothing from beautiful.
“Okay. I wanna…can I cum now?” He asked.
Korekiyo filled their palm with more lube before wrapping it around Kokichi’s cock, which had been almost completely ignored up until that point.
It barely took two strokes for him to start falling apart. Kokichi keened, lips forming words but not quite speaking anything.
Korekiyo talked him through every second of it: “There’s my perfect Kokichi, yes, my love, beautiful. So very good for me,” until Kokichi’s erection was spent in their hand, and his entire body was limp with satisfaction.
Korekiyo worked quickly, unraveling the rope first, then going to retrieve a bottle of water and some ointment for the areas Kokichi had fought against the ropes.
“Ah, Kiyo,” Kokichi shuddered as they applied the ointment, beginning to roll his sore wrists. “Thank you.”
Korekiyo smiled. “Of course,” they murmured, pressing a kiss to the top of his head. “I would do anything for you, my darling.”
With that, they returned to soothing all the places they’d hurt him.
Kokichi nodded, then sighed, the tension disappearing as he melted under Korekiyo’s hands again.
