Hottest Kiss of the Century
Muzan Kibutsuji x Annavenn Vallayerikh (OC)
This fiction is written by Cee (@_cranthir) on X for Kinktober event (by @redbluemiw) prompt “Standing / Against a Wall”.
One thing that Muzan despised the most in this life was — well, almost everything.
To be born a weakling. Everyone knew he would die before reaching the age of twenty. But he refused to succumb to such a dark fate. He was certain he was born into this life for a reason. After a lifetime of medication, when he was about nineteen years old, Muzan was turned into a demon through an experimental treatment for his terminal illness. Since then, his goal has been to live without the fear of death and become truly eternal.
To conquer the world, having everyone under his command.
That dream — to see the world burn as he created another paradise for those who were worthy. It would flourish into being, no matter how long it took.
Especially now, when he had found the finest thing in life.
He found greatness — not in his blood, not in a blue spider lily that could save him from the sun, but in the shape of another creature: Annavenn.
Beautiful, so divine. When he realized that Annavenn was the Guardian Angel who had accompanied him when he was still human, he knew he wanted her as his bride. Every passing second, it was her who had to be there. To be his queen, his demon queen. When there was blood on his hands, it felt like he had atoned for his sins whenever he touched her.
That was probably the reason why he loved it the most when all of his senses were overflowed by her.
“Come on, spread your pussy more, Annavenn.” Just like now. “Fuck, you smell so good.” He had his nose buried in her dainty, sweet-scented neck. The perfume he bought her, the soap, her natural scent, and everything that enveloped her skin just felt amazing.
He was practically addicted to it. Despite having him buried deep inside her tight cunt every day, the excitement never once lessened. Only amplified.
“Aahhh, Muzan — ” Especially when she kept calling his name like that. “T-There, right there.” He was feared. But by her, he was lusted over, loved. Worshipped. “Nghn, your nails feel so good!” Something he never thought was possible in such a miserable world like this one.
“I don’t need you to tell me where, Annavenn.” His tongue slithered out, licking the column of her neck. The sweat that she produced only made it tastier. “I know where to fuck your pretty pussy open.”
Annavenn could only let out a needy whimper. What a slut, he thought. My slut, and he continued. A grin appeared on his handsome face as his fingers delved deeper inside of her. It was so wet and warm inside. The ribbed walls of her pussy clamping around his long, thick digits. Even after all these years, she still took everything from him like a virgin, “Oohhh, look down, my love. See? Blood oozing out.~”
For anyone who heard it, that might sound as scary and freakish as hell. But it was as if the two of them ever cared about others — especially not at times like this. What Annavenn could focus on right now was how the sharp nails belonging to her beloved were practically grazing her sensitive cunt.
It hurt, but fuck, it hurt so good.
“B-Because of you.”
“Of course, it’s because of me,” Muzan hissed. “Who else would it be if not because of me?” He didn’t like the idea of someone else touching his property. “The only one who gets to kiss you,” he reminded her, “The only one who gets to undress you,” by fucking her gummy spot that got her body squirming in his hold. “Is me.”
He didn’t have to raise his voice; his knife-edged intonation was enough to make her pussy even wetter than before. Muzan should have been on his way to Ubuyashiki Mansion right now, but murdering someone could wait.
His beloved, Annavenn, was a pretty little being who needed to be marked over and over again. It was as if the bites and claws he left on her skin had no chance of fading, given how he devoted all his time to do her.
He pushed her back against the nearest wall. It rattled, and some could even see cracks in it, but he couldn’t care less. Right now, his fingers were going in and out of her pussy freely. It was so messy; some of her slick from her first high was dripping onto the floor. And oh, he was so freaking in love with how she could splatter her wetness everywhere.
Muzan stood between her thighs. Hitching her body up so her tits could be devoured so easily. He parted his lips wide before sucking on the skin near her areola, seeing some of it was still pristine. He couldn’t have that, right? After all, every inch on her body should be carved with either his mouth or hands.
“M-Muzan, ‘close!” The small squeak she let out only aroused him even more. His cock had been twitching inside his pants. The slit oozed precum, which only helped him fit inside her more easily. “Aahhh, I can’t hold it — ”
“Moan my name, Annavenn.” he growled, leaning away to see her expression. Her face scrunched up with pleasure, sweat beading on her forehead as her luscious blonde hair stuck to her skin. “Let me hear you, let everyone hear you.”
He feverishly rubbed her engorged clit, pressing it with his thumb as he played with it as if it was his favourite toy. Then again, she was his favourite toy indeed. His fingers continued to curl inside of her pussy, knowing each part that he should touch to lock in her high. He bit her chin, nibbling on the soft skin before he went to her lips, “Come on. Be a good girl for me like you always do.”
His fingers moved in and out so smoothly, picking up the pace that he knew she liked. Her pussy juice trailed down his wrist, fingers were already wet.
“Muzan…!!!” But when she squirted all over him, “Ahh~ ‘s good! Need more, need more!” His fingers, pelvis, and wrist were now absolutely soaked.
“Fuck. Always so needy, aren’t you, my dear?” His eyes turned into the darkest shade of colour whenever he was with her. Lust and carnal desire running through his veins, ready to just take everything from his pretty prey. “Then, more is what I will give to you.”
He didn’t waste his time. Ripping his own pants that his cock immediately slapped against his own lower tummy. The veins could be seen on its skin. Cockhead reddened and swollen, ready to just have it shoved deep inside of Annavenn.
His cock slipped in between her thighs, letting her slit wet him even more as his hands went to her tits. Muzan’s personal plush, he could bite on it, ravaging it for as long as he wanted to. The nipples were pink and so enticing for him to just suck on it. And he usually did that, until it was bleeding a bit with how rough he was.
But he needed to go somewhere after this. Sadly.
So he had to make this quick — as quick as he could, anyway. At least until he could make her cum at least three around his dick. Then that would suffice for now.
After all, he could always continue once he was done with his mission.
Muzan’s hand was attached to her waist. His tongue found its home in her mouth, swirling around the wet cavern that got him so drunk of her. Once he felt her slit against his cockhead, he didn’t waste any other second and lined himself more. Without releasing his soul-devouring kiss, his fat and aching dick spreads her tight vaginal walls, “Ohhh, fuck. So good, so pretty taking my cock.”
His beloved had her hands wrapped around his back. Her nails were digging on his flesh, and she moaned his name in sweet delight that got his hips jutted forward. With how the two of them kissed, her chin practically covered with shared spit. She was drooling, needy of him. He only had half of his cock inside of her right now, and the whine that escaped her lips only showed that she demanded more.
“Nghn, need it.” What a needy little creature she was. “Shove it all. Give all of you to me, Muzan. Please, I need it, need you — ” how could he ever resist?
Without waiting for another second to pass, Muzan spread her thighs to the side and pushed the whole length inside of her. The tip effortlessly slipped past her cervix. Making her toes curl as he growled when he felt her gushing around his cock with just him bottoming out.

“Shit. Did you just cum again?” He knew the answer to that. Already knew the feeling of her clenching pussy when she reached her orgasm. But he wanted to hear her voice. Always craving for it.
“Y-Yes!” Because whenever she croaked out with that slutty smile on her face, it got him so freaking satisfied. “More, Muzan! Want you to do me more!”
“Heh,” He licked his own lips. With the tongue that was usually used to devour her. “You don’t have to ask me twice.”
Muzan pulled his cock, leaving just the bulbous head before he ploughed it back inside. Knocking the air out of her lungs that her tits bounced alongside his thrust. Her nails stayed on his back, lips parted wide, shaped into an o. What a pretty being, he couldn’t stop drilling his aching cock deep inside of her warm pussy.
“Aahhh, ‘s big!” The blood from the previous foreplay was still wetting his cock. It was as if he was fucking a virgin over and over. Then again, with how her hot cunny wrapped around his length as if not wanting to let go, she felt like one.
“Tell me whose pussy is this.”
“Yours!”
His pelvis smacked against her clit. The wispy hair was enough to give more friction as he kept being balls deep inside of her. She couldn’t think about anything else at this point. Just the huge cock of her Muzan. She was always so drunk to the pleasure that was bestowed upon her by hers truly. And he was the same.
No one could ever make his heart spike up like how she did it.
“And who is this… yours?”
Annavenn’s ass was practically knocked against the wall. With how hard his dick digging into her gummy spot at a rapid pace, it was by miracle the wall still stood tall. She ‘only’ came three times. He needed her to cum at least one or two more times before he let her go.
And after he was done with his business, her pussy would be greeting him back.
“Y-You, Muzan!”
“Who?”
“Muzan-sama!”
“Good girl.” He buried his face at the crook of her neck, taking a deep breath as he had his hand clawing on her ass cheek while the other kept her legs up by holding her thigh. “My good girl.”
His voice was embezzled with lust. Carnal desire taking over all of his senses that he knew even if the world suddenly burned into flames, he too would continue moulding her tight walls into his shape. His claws dent along her plush flesh of her ass and thighs, guiding her to his pace as he fucked harder.
She was close, his dearest was already close again. Her head would often bump against the wall, but he didn’t mind that at all. After all, the mix of pain and pleasure was always her go-to every damn time. He caressed her ass, only to smack it over and over again that the loud smack could be heard throughout the room.
“Your good girl, yes! Always!”
“Mhmhm, I know.” Leaning away, he could feel his cock twitching inside of her. The swollen, reddened head knocking against her womb to the point her body kept shaking in his hold. “My good girl that loves being fucked dumb.” A sly grin entered his face, loving when her head just emptied whenever she took his cock.
Her cheeks were flushed, drool could be seen trailing down her chin. Those pretty eyes of her rolled to the back of her head when he repeatedly nudged her sweet spot. He was close too, but he wanted to cum together.
“Like being fucked dumb by you!”
“Ding ding ding, correct again.” And when he filled her up, he needed her to look at him. “Now, eyes on me. Gonna shoot my load inside you,”
“B-But I am looking at you!”
“Then keep it like that.” His voice was stern, forcing her kaleidoscopic eyes to lock with his gaze. “I want you to watch when I fill you, my dear.”
He pressed his forehead against her, and he was so tempted to swallow her whimper and moan. But he stopped himself from doing so. He could do that later when he comes back. “Come on, cum. Cum for me, Annavenn.”
His hips moved sloppily against her, chasing his high too as her walls clamped around his aching dick. His breeded balls were ready to be emptied inside of her.
“Muzan! Cumming, cumming — ”
And when she gushed all over his length, he let out a growl and dug his nails into her flesh. Just like how she clawed against his broad back, needing something to hold on as her body convulsed in front of him. Her legs quivered, but a lewd smile appeared on her face when she felt him spurting his creamy, thick semen deep in her womb.
He shuddered. Pushing her body even more to the wall. The base of his dick was bigger, plugging her pussy up so she wouldn’t waste even a drop of his cum, “O-Oh, God~!”
“Fuck, calling me, eh?” He teased. Body shuddering as she only let out a mewl. His thrust had gotten slower, wanting to relish and bask on the high that he had with her. “Aahhh~ Look… Look down, my dear. Look down and see how some of my cum is still dripping down the floor.”
“I am sorry,”
“Sshhh,” He cooed at her, kissing her chin oh so softly. “Don’t worry. Once I am done, I will come back and make sure none of it slips out from your pussy, alright?”
“Alright.” Her voice was so sweet. All the candy in the world wouldn’t top it. “Come back soon…?”
“Of course.” Even now, he didn’t pull away just yet. Letting him feel the mixed cum oozing out from her plugged slit, and plop down to the floor.
He just stood there. Keeping his huge cock that she loved so much buried deep inside of her. Her walls warming him up and fuck, if only he didn’t have to go. Then again, another few minutes delay surely would be alright. He released her thigh, letting it wrap around his waist instead as he continued to grind his dick.
What a needy being he was, but so was she. Muzan caressed her cheek with the back of his fingers, his gaze was enough of a promise that he wouldn’t be long. “When did I ever make you wait, my Annavenn?”
Unfortunately…
