AYOOOO??? *rubs my hands together and giggles like some pervert* I think I picked the most difficult character for no reason-
This was ridiculous, nothing more than a joke. He was the one who received the most blood from him, he was the one honing his skills for centuries. So obviously he was supposed to be the strongest, second to none but that man alone.
Then how did you get here? Appearing out of nowhere, causing an uproar in the ranks. You were only a few decades old, too green behind the ears for your position, not to mention too obnoxious and childish. At the same time you were undeniably talented, climbing the ranks like nothing, surpassing others whose had way more blood than you, eaten way more people. Surpassing even him.
It reminded him much of a certain other person, which was not helping your image. How was this even possible? Is this what pure talent and sheer luck looks like? He was frustrated beyond words, and to some degree, he envied you. Jealous of how a snobby kid like you could have beaten him by miles, taking his rightful place next to the lord as one of the strongest. No, never, he wasn’t going to be satisfied with third place.
That mentality of his paired with his disapproval of you is what caused your current situation, it was the root of this shaky relationship.
“Hey, old man! You’ve gotten better since last time!” You commented in a sarcastic manner, sitting down on a fallen-over tree trunk. That indolent tone of yours again, you had no respect for your elders. On the other hand, you were stretching your body and twisting your wrists, as if you didn’t even get to warm up, eyes sneakily darting to the demon in front of you.
A man with long hair and a slightly torn purple kimono was kneeling on one knee a few meters away from you, his grip shaking around his weapon. “…but you might wanna work on your endurance, I can’t work with that.” You smiled innocently, jumping to your feet again. With leisure steps, you walked closer to him, grabbing his chin and making him look up at you.
His six eyes all glared at you, a red glow of fury radiating off him. You weren’t intimidated though, maybe you were when you used to be a lower moon, but not anymore. “After experiencing it firsthand, no wonder I managed to become an uppermoon so soon. You bunch are weaker than I expected.” That taunting voice of yours, paired with that mocking smile, you really knew how to provoke someone.
Kokushibo grabbed your collar and lifted himself up, “really, you should learn when to shut up.” You let him do it, not resisting while asking, “hmm? What’s gonna happen if I don’t listen? What, you gonna fight me?” An uncontrollable series of laughter escaped your throat, “and you always stressed the importance of respecting the ranks~!!”
His fist clenched around your clothes, and you smirked once you noticed it. Your words were getting to him, despite his indifferent facade. Good, how fun. You had him exactly where you wanted, any second from now he should— “let’s have another duel.” —aha, there it is. “Well that’s certainly not a problem, but I’m kinda getting bored over here.” You slapped his hand away, then straightened out your clothes, “I mean, why should I keep wasting time here? It’s not like I get any benefits.”
No matter how annoying you were, and how much he hated to agree with you, you were right. Since he just lost, it was pretty unreasonable to wish for another duel so soon. “What are your conditions.” Kokushibo said in a low voice, still glaring, not bothering with keeping a calm facade with you anymore. He brushed off the dust from his shredded kimono, which revealed little snippets of his muscular form, ranging from his biceps to his abdomen.
“If I win…” You crossed your arms in front of your chest, then pointed at him with your index finger, “I want you to do whatever I want for today~” judging by the way your voice got higher towards the end, you were clearly enjoying yourself. How irritating. Its to be expected that you are a little screwed. A normal person- demon -wouldn’t be able to climb the ranks like you. But he still agreed to your condition, because his priority was to beat you and have things return to its original state. “I accept.”
This poor thing and his inferiority complex, his vulnerable little heart with that frail ego of his.
You weren’t sure what he was expecting, considering you’ve just beat him a couple minutes earlier. While he was a tough opponent, who improved drastically in a short period, it wasn’t enough to sweep you off your feet. The result was set in stone the moment he agreed. A part of you was actually hoping he did it on purpose, because he wanted to know what you’d do to him. Though obviously that was just wishful thinking, there’s no way this man would do that.
No matter how often he lost, he’d never get used to the humiliating feeling, the awkwardness that followed. Especially now, since on top of losing, he owned you something. Maybe he shouldn’t have made that bet, he kept thinking, but he was too stubborn to back out now. “What do you want me to do?” Kokushibo sighed, eventually facing reality and lowering his head with a scorn. You couldn’t hold back a smirk and said, “first, promise you won’t get too~ mad.”
He knew he promised, well, you basically forced him to, but still. For him to run out of patience and get angry so soon, only you were capable of doing this to him. “You are shameless.” The male groaned with furrowed brows, his wrists straining against the rope tied around it. You could see him tensing his muscles, did he hate it that much?
All you did was tie him to the bed and loosening up his kimono, positioning yourself between his legs. Maybe slipping a hand underneath his clothes to grope his chest, it’s not your fault he looks so inviting. The rope was already making snapping sounds, even though you told him to control his strength. “Geez, and why did I went through the trouble of learning bondage again?” You clicked your tongue in disappointment, but untied the rope.
“It was a stupid idea to begin with. Why do you even want my body?” Kokushibo frowned, trying to sit up, thinking you finally gave up on your goal. But you grabbed both of his wrists instead and pinned them over his head, “what kinda question is that? Isn’t the normal conclusion that I find you attractive?” You chuckled a little, as if surprised by such a naive question.
He flinched when you suddenly yanked his arms up, and asked in a rather hesitant voice, “wait, why are you still..?” You tilted your head to the side, acting a little cheeky, “what, you thought i was done? I haven’t done anything with my price yet.” A moment of silence passed, all he did was focusing his eyes on you, in search of any hints that you were joking. There was none, despite you smiling brightly.
“…you still want to keep going?” The way he couldn’t even fathom the words that came out of his own mouth. Just, it was too out of place. I mean, you- with him? Have you always had such intentions towards him? “Kokushibo, you are acting as if you’re an old man. Oh wait, you are.” You teased, pulling at the waistband of his pants. “Ah- wait—” he felt a weird tingle spread where your fingers touched his skin, he brushed it off as him being irritated.
Seeing him so embarrassed at the smallest exposure, you decided to do him a favour and simply slipped your hand inside. At the same time, you whispered sickeningly sweet, “just relax, alright? I will do my best to make you feel good too.” The hand that was clumsily messing around finally found a starting point, and was slowly caressing his inner thighs. You didn’t need to probe long to find out he was muscular, not that you doubted it for even a moment.
“Say…” with a little more assertiveness, you pushed your head into the nook of his neck, mumbling against the part of his neck right under his ear, “won’t you allow me to?” About half of his eyes were closed and the others half-lidded, but he was definitely avoiding your intense gaze. How did you say such things with no shame while keeping eye contact? He gulped loudly, bawling his hands into fists above his head, “now you are asking…”
“Hmm? Don’t want to?” You tilted your head, to mutter directly into his ear, blowing air at the shell. The man flinched at the notion, and he groaned, “I already agreed since you won… what more do you want?” Such a temper, he was acting more like a cat than a demon. “Let’s see, how about you being honest with me?” Without any warning, you let go of one of his wrists and brought the other one to your lips, placing a kiss to his palms.
“You-!” He jumped at the sight, finally looking at you again. Never in his pretty long lifetime has anyone behaved like this towards him. At this point, he didn’t even know what he wanted. It was only because of the bet, that’s the mindset he had when he entered this room at least. But would he have the same one when he leaves? “…I’ll tell you when I hate it.” And that was it with the eye contact, with his pupils rolling to the side again. Seriously, what was so interesting about starring at walls?
“So you are tolerating it until then?~” you sighed, acting as if you were hurt. While he was distracted by your acting, you wrapped his arm around your neck and leaning down to pinch his cheeks. “Don’t be shy. Tell me, doesn’t this feel good?” You clasped your hand around his half erect dick, measuring him with your fingers. For no particular reason, you just wanted to keep your hands busy. He hiccuped at the friction and twitched, unable to keep his hips under control. “HnnG..?! Ahh…”
Gosh, his moans were really addicting. You almost lost your reason there. Moving the hand on his face a little to tilt his head, making him look up at you. “Tell me, kokushibo.” Hearing you say his name like that felt strangely foreign, you were really putting your all into this. He clenched his eyes shut as his blush darkened, squeezing out a quiet, “feels good..” What a relief it is that he doesn’t know the power his voice has over you, that little confession was enough to make you beam with delight. “Seriously, why do you keep seducing me~?”
Seduce??? He couldn’t even argue with you before you suddenly pumped him up and down, causing him to jump a little. “Ugh..!” After getting his consent, you weren’t holding back as much anymore. Pulling his pants down to reveal his groin without a second thought. His arms clawed at your back instinctively, and despite him expecting this to happen, he couldn’t hide how ashamed he was.
“My my, you are pretty wet down here.” You commented, noticing the way he kept leaking precum. Soon it covered your entire palm, and you used it as lube to spread it evenly around his sex. “Haaah… what do you mean wet…?” Ah- right. This man, even if he looks young it didn’t mean his mental age is the same. But explaining it would kind of ruin the mood…
“I mean, look how much’s comin’ out.” You rubbed his tip, turning your hand around as he shuddered, arching his back off the bed. Once you were satisfied with the amount of pre you’ve collected, you proudly displayed it in front of him. He shot one quick glance at the thick fluid coating your fingers and squeezed his eyes shut, whining out a “stop that.” For some reason, you felt offended by his reaction, responding with a “why do you look disgusted? This came out of you!”
“No need to shout it.” One of his hands moved to cover his face with the back of his palm and he clenched his teeth. Really, what were you going to do with this overly sensitive man? “Aren’t you hard to please.” You rolled your eyes, but ended up giggling over it. “Fine I’ll stop.” In return, you moved the hand on his cheeks down to grope his firm chest. The texture was softer than you expected, considering it was pure muscle.
After uttering that, you wrapped the dirtied hand around his shaft again, and jerked him off slowly. Due to the awfully slow motions and the fluids, it created filthy squelching sounds that bounced off the walls. His breath hitched at the sudden rush of pleasure, and his toes curled into the bed sheets. The way his chest heaved and his breathing quickened was too cute, not to mention his melting expressions mirroring the bliss he was experiencing. “Ah- ahhh…” even the way his lips parted was cute, what to do?
You noticed how his hips were jerking, dick twitching in your hand. That, paired with the erotic view laid out before you, manifested your desires even more. It was as if you were in a trance, unable to peel your eyes off him, staring at him like a hunter at its prey. His hair was spread out on the bed so beautifully, and you were ecstatic to see his body tremble with pleasure. You subconsciously quickened your pace, wanting to see more of his debauched state.
“Hnngh,,,Y-y/n, wait.. ah, just- s-slow down… a bit..” he had a troubled expression now, cheeks flushed red as he clawed at your back, trapping you in his arms. When the burning sensation in his core didn’t stop but intensified instead, he accidentally dug his nails into your skin, leaving behind some scratch marks. “Please, y/n…” the male begged in a gentle tone, lowering his head as the embarrassment finally got to him.
Isnt this the first time he used your name? …haha, this isnt fair, he moaned out your name in such a lewd manner, who wouldn’t fold instantly. This time you were sure, if he knew the power his voice had over you, he’d win every competition between you two. You chuckled awkwardly and mumbled something under your breath. He couldn’t quite catch it, because he couldn’t focused on anything else but the drag of your hand across his dick. The agonising tingles that made him go mad, the warmth and comfort of your touch.
“Nghhh- mhm!!… y/n, y-y/nnn…♡♥︎” he slurred over his words, hands fisting and pulling at your clothes. All these sensations were too much for him, the last time he felt anything remotely similar to this was when he left home. No, even then, it was never this stimulating. The way his entire body was like on fire, shaking with the overwhelming amount of raw arousal flooding his senses. Every single touch, every sound of your voice was messing with him.
You swallowed the lingering hesitation down, and circled around his nipple with your index finger. It didn’t take long before it hardened, quivering shamelessly. All while you moved the other hand up and down his sex. The more noise that movement made, the louder and more frequent his moans got, and it all mingled together into a lewd melody reserved for your ears only. It seems he knew how loud he was, because he suddenly bit down on his bottom lip, enough for it to swell and bleed.
“Now now, don’t hold back your voice. I wanna hear you callin’ my name for everyone to hear.” The vibrations of your voice tickled his sensitive skin, and he turned his head to the opposite side, granting you more access to his neck. His heart pounded in his chest, skipping a beat at the thought of others hearing his pathetic whines. Causing him to react with sealing his lips shut with more fervour, body flinching at every seductive spell of yours.
“I thought I told you to call my name? Aren’t you gonna do it, kokushibo?” You asked, placing gentle kissed from his jawline down to his collarbone. Not enough to leave marks, you wanted to take it one step at a time. “Come on~” you placed your thumb on his slit and rubbed around his tip, ending up with him leaking even more.
He tried to clench his thighs together but to no avail, it was as if his muscles couldn’t respond to him. Going limp under your actions. “Y/n…” he eventually groaned out. After hearing him say that, you bit down on his shoulder, leaving your first visible claim. Though he could heal it in a second, you still loved the thought of leaving bruises on him. “Good boy.”
Muffled groans and whimpers spilled from his sinful lips, his brain was too mushy to function coherently. Everything was too much for him to handle, and he felt tears streaming down his face. From the upper eyes to the lower ones. It was quite the weird feeling, so he blinked the tears away, trying to control his sobbing as he chirped, “y- hnNghh…! Y/n..?” How could he let himself be ruined and reduced to such a pathetic mess? Breaking down in tears at such an insignificant thing, letting you take charge like that…
The way his tone drifted off to being unsure and questioning was so adorable, you basically grinned from ear to ear. “Look at you, crying so prettily. It hasn’t been that long since we began.” He must have been so touch starved, to become such a cute mess because of a handjob, that was the downside to being at the top. You finally flicked and played with his nipple after teasing the surrounding area for so long. He cried out like it was the last straw of his sanity breaking, turning him into nothing more but a blabbering wreck.
“Ah-arghh…, I ca-can’t.. haah, urgh..! I’m close, y/n, p-please..” where did he learn to plead like that? It gave you goosebumps due to how erotic it was. “Aww, gonna cum? Go on, let it all out~” you kissed him, using his shock to your advantage and sticking your tongue inside his mouth, tasting the faint metallic taste of blood. At the same time, you fastened your pace on his cock, making him shudder and wither into the kiss. He continued to weep, to hold onto you desperately while he squirmed around, wriggling his hips as if he wanted to escape the pleasure. Your tongue fumbled around with his, drinking up his moans.
Though muffled, your ears picked up the bits that did seep out, and he was chanting your name like a prayer, just as you wanted. His eyes were glazed over and unfocused, sweat and tears were now mixing with drool as well. And the blush crept onto his cheeks has spread like a pest, to his ears and shoulders, as well as his chest. Slowly, he felt the strength leaving his limbs as the ecstasy threatened to consume him whole. He’s been teetering on the brink of release for a while now, the building anticipation was agonisingly slow. “Mhmmff- uhhh, hmm~!! ♥︎♥︎♥︎”
Suddenly, his back arched off the bed, and his nails dug harsh enough for your skin to tear. You pulled back once he started choking, and he immediately lunched at you, to hide in the nook of your neck. “Haaa-hah, hnghh- hmmff…” that’s when he caught you off guard by biting into your shoulder to keep his voice down. “You surprised me there.” You flinched before running a hand through his long hair, stroking him. The wound was nothing serious anyway.
“Haaah… y/n, y/n, ooOhhh, y/ny/n y— hmmnfff~~♡♥︎♡” he moaned out one last time as his release washed over him. Soon a sticky white fluid spurt out of his aching dick, coating the entirety of your hand to the point of dripping down his own shaft. It pooled around his pelvis or flowed all the way down his thighs. Once your hand separated from him, strings of cum connected the two. Even after cumming, he was breathing heavily, mumbling your name softly while catching his breath.
You slowly guided him through his orgasm, cooing at him, “good job, such a pretty thing, aren’t you.” His body was still shivering in the afterglow, but he managed his breathing pretty fast, and thus the hiccups got better. It didn’t take long before the high washed off, and while he was still disoriented, he was already starting to feel ashamed again. Pulling back as he tried to blink away the shame. This was so humiliating, how could he cry in front of you- At least his crying stopped now.
Then he flopped back onto the mattress, turning his head to the side to hide it behind the fluffy pillow, as well as using the back of his palm to cover his face. A few minutes of silence passed, where he was busy shorting out his thoughts. He really did that kind of thing… with an inexperienced brat like you… “a-are we done now?” Once he was certain he could speak coherently again, he spoke up. “Well…” in the meantime, you’ve spread his legs apart and used the cum-covered hand to reach to his backside. “…it’s time for me to have some—“
Before you could end your sentence, you noticed him drifting off to a peaceful slumber. “Kokushibo? Hey, kokushibo??” You rubbed his cheeks, wondering if he really just passed out like that. “…hah!” You couldn’t hold back your laughter, one orgasm and he’s knocked out cold? Hilarious. “I told you to build up some endurance, old man.”
