The moon trickled through the trees above you, the blade of your katana reflecting the light as you held it high after inflicting the final blow on the demon you'd been sent to kill. You watched as its body crumbled beneath you, cursing you to hell as it slowly withered away. Your breaths were as calm as ever, this demon being nothing compared to the ones you'd slain before.
"Light work," you muttered to yourself, sheathing your katana and taking a moment to scan your surroundings. Although you'd completed your mission, you could still sense that something was off. You weren't alone. You'd mastered the act of keeping your guard up now, but you were nowhere near as skilled as a Hashira, which is why you almost didn't notice the eyes up in a nearby tree trained on you. You grabbed the hilt of your katana, heart thumping against your ribcage as you sized him up. He was nothing like any of the measly demons you'd been fighting; he reeked of something you couldn't quite put your finger on.
"Water breathing, first form-" You drew your katana, but before you could even assume your fighting stance, the demon disappeared. You couldn't sense where he was, but you could feel his presence. Collect yourself you thought, but before you could even turn to face his looming aura, your katana had been swiped from your grasp and your legs kicked out beneath you, leaving you defenseless. He laughed softly, throwing your katana to the side and looming over you.
"I've been watching you…waiting for this moment for so long," he said, his voice dripping with excitement. You cowered below him, but he gently cupped your face, forcing you to look at him. You felt your heart drop as you stared at his eyes, realising the severity of the situation.
Upper 2
His face changed to an almost concerned look as he noticed your fear.
"I can't stand seeing you scared,"

"W-What do you want from me?" You managed to get out, fear almost incapacitating your ability to talk. An upper rank wouldn't go out of their way to prey on a mere corps member. You were nowhere near a threat to him or the 12 Kizuki.
"I want…to fill you with my blood," he gripped both sides of your face with an almost maniacal grin plastered across his face.
"No. I won't let you," You glared, willing yourself to calm your breathing, desperately trying to mask your fear.
"I've seen you, the way you fight is…breathtaking," he complimented, sighing dreamily. You'd always been given compliments on your fighting style, people often comparing you to a ballet dancer as you fought with pure elegance.
"But-" his face contorted into one of concern. "-you're weak." his thumb swiped over your trembling lip.
"You'd never make it as a Hashira," He pouted, feigning pity. He dropped you to the floor, and you used this opportunity to grab your katana and attempt an attack.
"Water breathing third form: flowing dance," you struck him with your sword, but you were nowhere near strong enough to slice through. The most he got was comparable to a cat scratch, and yet pain coursed through you. Your knees buckled, and Doma stalked towards you. As a last resort, you pointed your katana towards him, and he just let it glide into him. In fact, he put his hand over yours and guided it through his stomach with a weirdly calm smile on his face. Doma was a demon obsessed with the beauty of femininity, so it was no wonder he took a liking to your fighting style. The fact that he knew you were of no threat to him only encouraged him; he felt like he could mould you into whatever he wanted.
"Y-You're a psycho," you cried out, hand trembling beneath his as he pulled your katana out. He regenerated almost immediately, but the blood on your sword remained. This time, the blade pointed towards you.
"Let me make you a demon, join me. We could be so powerful,"
You shook your head, cowering away from the tip of your blade, tears welling in your eyes. You never thought your own sword would be used against you.
Doma sighed, pouting slightly as a freezing mist began surrounding you.
"It pains me to do this.." He watched as you gasped, the cold air hitting your lungs.
"Such a waste," he nicked your cheek with your sword, blood droplets appearing across the mark he'd made.
As soon as the blood on your cheek fell, you saw a change in Doma's eyes. He looked…hungry, but not in a way that he wanted to eat you.
"Marechi," he whispered, a grin appearing on his face.
Marechi blood was often intoxicating to weaker demons, significantly reducing their cognitive ability, but more powerful demons have a high tolerance to the effects of it. Yours, however, seemed to be affecting him in a way you hadn't seen before. The scent drove him crazy, his rainbow eyes darkening as he hungrily loomed over you.
"P-Please," you whimpered, fearing for your life. He threw your katana aside, wiping the blood from your cheek with his thumb, making you wince. He swiped his thumb over his tongue, the faint stain of your blood coating it before it disappeared back into his mouth.
"I want to know how you'll taste between my teeth," his smile was that of a psycho, and you braced yourself as he honed in on you, expecting him to start devouring you. But it never happened.
Instead, Doma nipped harshly at your neck, and you whined at the sharp pain before you felt the blood drip over your collarbone. He hungrily licked up the mess, and you felt your breath hitch.
"What are you doing?" You asked him weakly, but he didn't answer. He fed on your blood as you whimpered underneath him, helpless. He stood back to admire you, swiping his tongue over his bloody fangs. Your blood had stained the collar of your corps uniform, and he shook his head at the sight.
"I'm so sorry, I've made a mess of you. Let's get this off," He smirked, undoing the buttons on your shirt and throwing it to the side. He hummed as he took in the sight, a helpless victim trembling before him.
"It pains me to see you like this," he dropped to his knees, putting his two hands on either side of your shoulders.
"Let me make you feel good,"

It's almost like tasting your blood had an aphrodisiac effect on him, his eyes clouded with lust as he grabbed your chin.
You'd be lying if you said you hadn't enjoyed the feeling of him licking and biting at your neck, but you couldn't shake the thought that this was a demon. An upper-rank one at that. Still, the dampness between your legs wasn't going to do you any justice. You knew there was no point in fighting him off, he could easily just kill you. There were no other options but to submit to his will.
You looked up at him, and he smiled down at you. It almost looked genuine.
He brought his lips to yours in a hungry kiss, and you couldn't help moaning into his mouth as his free hand explored your exposed skin. His hand was cold, contrasting the warmth of your human skin. His lips found your neck again, the scent of your blood leaving him hungry for more. His teeth nipped at your skin, drawing more small droplets of blood.
Doma had you completely at his disposal, and he relished in the fact.

"You'll be mine by the end of this," he murmured, no hint of doubt in his voice.
"I want to keep you forever,"
His hand found your nipple, fingers grazing over the perky bud before pinching it lightly. He watched your reactions closely, pinching slightly harder when he noticed your chest rise with a gasp from the feeling.
"Please, I-"
His movements stilled, and his face moved closer to yours.
"Please what?"
You suddenly became hyper-aware that he wasn't touching you, all the places he'd touched you burned longingly as if he'd branded your skin.
"D-Dont stop…" you whispered, and Doma wasted no time pinning your arms above your head.
"I'm not going to stop…until you're begging for my blood," he smirked, and his hand slowly made its way to the hem of your panties. He effortlessly ripped them away from your body, the cold air from Doma causing you to gasp as it made contact with your middle. He rubbed a few teasing circles into your clit, your eyes fluttering shut as your head tilted back underneath him.
"Look at me. I want you to watch your innocence wither away at the hands of a demon," You didn't hesitate, pulling your lip between your teeth as you watched Doma tease your clit. He didn't keep it up for long, moving onto your dripping hole that had been desperate for something to fill it. His glacial skin compared to your heat sent a cool chill up your spine, goosebumps appearing over your exposed body as he slowly slipped a single finger into your desperate hole. Doma studied your face, noticing every change in your expression as he pumped it in and out of you with ease, your lips parted, soft, breathy moans leaving them, and eyes trained on his
"Hmmm, such an obedient little human you are," he praised, noticing how you clenched around him at his words. His finger curled, grazing against that sweet spot inside of you once before slowing his movements to an agonising pace. You writhed beneath him, and Doma smirked as he watched your hips search for something more.
“Please,” you breathed, and Doma’s free hand held your hips still as he teased you even further, his pace almost torturous.
“S-Stop, please I want more,” you pleaded, and Doma added another finger as he pushed them back into you, curling them both into that same spot over and over.
Your heart pounded from the intensity of the pleasure, and he could sense it. He could feel every fibre of your being as he filled you with his fingers. When he felt your walls tighten around him, he brought his thumb up to rub small circles into your clit to bring you closer to the edge. It didn’t take long at all before the intense wave of pleasure rushed over you, loud moans tainting the otherwise calm woodland atmosphere.
His free hand clamped over your mouth as he fingered you through your orgasm, moans muffled against his fingers.
"Perfect, you've reached a state of bliss," he smiled, and you fell limp beneath him.
"At this point, I would've already devoured you," he ran his tongue over his fangs as he took in your fucked out expression.
"But I'd be a fool if I didn't try you out for myself, wouldn't I?" The sound of his belt unbuckling grounded you back down to Earth, coming down from your pleasure induced high. You watched as he pulled his pants down slightly, just enough to reveal his cock, your eyes visibly widening at the size. You could've guessed he'd be well endowed from the fact that he was a demon. You wondered if he'd even fit inside you, the mere thought of him struggling fit in your cock-hungry pussy almost had you moaning.
"Don't worry," his hand gently grazed your chin, bringing your eyes to his instead.
"I won't be gentle," he sneered as he turned you over, lifting your hips up so he could position himself. Despite his words, he started slow, sliding himself in inch by inch until he couldn't anymore. The stretch was unimaginably painful, tears welling in your eyes as his cock stuffed you full.
"You take it so well," he hummed, claws digging into your hips as he slowly rocked his hips against yours. The wetness from your previous orgasm glistened on his length, his thrusts becoming easier each time he buried himself into you, pain slowly subsiding as pleasure took over. Your moans were high pitched and whiny as he used your hole, his cock reaching places that could never be touched by another human. Everything he did reminded you that he was a demon, but you didn't feel ashamed. There was no room for shame or dignity while he had you bouncing on his dick for his pleasure, completely at his disposal.
"You have no idea how hard it is for me to not completely ruin you right now," he whispered, grabbing a handful of your hair and pulling you flush against his back. His pace didn't let up as he held you there, loosely wrapping his arm around your neck.
"I'll have to save that for-" he groaned, cutting himself off, hips stuttering slightly.
"Mhm, for when I make you mine forever," His free hand cupped one of yours, urging you to touch yourself.
"Make yourself cum for me, sweet angel," he maintained a rhythm again, slightly slower, but deep enough to set your nerve endings alight. You obeyed, rubbing circles into your already sensitive clit to bring back that all familiar feeling.
He groaned as your walls tightened around him, the extra stimulation being just what you needed to feel the pool building up in the pit of your abdomen. He didn't stop, keeping the same pace as your fingers desperately urged for that sweet release, and you swear you saw stars the moment it hit. Doma held you as your legs gave way beneath you, fucking you through another orgasm, curses and moans leaving your mouth before your body went limp with bliss once again.
Doma used your hole, giving you a few more lazy thrusts before he followed suit, hips stilling as he released ribbons of white inside your abused pussy. He placed you down after pulling himself out of you, a mixture of both of your cum dripping from your pussy as you laid there, drunk on sex. Doma redressed himself, and grabbed your katana that laid forgotten on the floor. You could only watch, your mind fogged in a state of ecstasy, as he walked towards you with a concerned look on his face.
"My, what a poor, sweet soul!" He mocked, taking your katana and making a small slice in his hand.
"Come, drink my blood and I'll take care of you…forever," he smirked, knowing he'd won. You couldn't fight him off in the state you were in, one of his hands holding your mouth open so he could pour himself into you.
"As obedient as ever," he smiled sweetly, scooping you up in his arms.

"Let's get you out of here, I'm sure Muzan will be pleased to meet your acquaintance,"
