A/N: the prompt for today is: Demon Sex Rengoku I had in mind while writing this.

It was normal for people to leave the Demon Slayer Corps. Some of the slayers left because of health problems, injuries, or were forced to leave by death itself.

Hashiras weren't usually seen leaving with demons, but your master left with one. 

Kyojuro Rengoku was more than just your master; he was also your lover. The pain might have been doubled because of that.

His actions were unexpected. As a man of honor, he always put others' safety before his own, so why would he do such a thing? His wounds or all the blood he lost may have prompted him to do this.

All those questions were on your mind after you saw him leaving with the demon.

The results of a Mugen Train were many people saved, broken hearts, and a traitorous Hashira.

With a heavy heart, you chose to remain a Hashira of Demon Slayer Corp; you were no longer an apprentice. You were always wondering if your former Master would cross paths with you again.

Many missions were sent to you, some more challenging than others, but the most recent was the most challenging. Due to that, you were sent back to your estate to rest before being called upon again.

Unlike any other night before, this one was completely hellish; nightmares and anxiety were constantly bombarding your consciousness; not even nights where you were recovering from deep wounds were as difficult as this one.

Tired of tossing and turning, you decided to go outside and get some fresh air to calm your racing mind. Your eyes slowly closed as you sat on the egawa, as if your body was trying to rest.

"Look at you, my dear Y/N, my tsuguko, my beloved."

When you heard the familiar tone, your eyes snapped open to reveal Kyojuro's face: gray skin with a red, flamelike pattern, red eyes with yellow, glowing pupils, looking right at you; his hair was long and looked like a real fire.

It would have been wise for you to panic, you should have taken action, you should have attacked the demon, you should have beheaded it.

Nonetheless, you did not act in this manner.

A smile spread across his face as your hand moved to cup his cheek; to your surprise, he felt warm to the touch; with a smile, he nuzzled your hand. "My little flame," he whispered, kissing your warm hand. "I couldn't bear another moment without you," Kyojuro confessed, pulling you into a tight embrace.

Your body was stiff and there was no way you knew what to do. He was a traitor, a demon, but at the same time he was Kyojuro, your master and lover; you had missed him for so long and he was here, hugging you tightly like he always did.

As a final gesture, you nuzzled his shoulder and returned the hug.

There was something wrong; you couldn't pinpoint what it was but this feeling didn't give you any peace. The world crumbled suddenly around you and you awoke with a soft gasp and a short moan. It was just a dream, a fairy tale reunion.

You were feeling the coldness of the night on your skin and wondered whether or not you had closed the window. As you reached for your silky nightgown to be tightened around your body, you discovered that you were entirely naked. Your body trembled from the sensation of something warm pressing against your clit and something filling your pussy, massaging your inner walls.

"Fuck!" You whined, staring into the glowing eyes of the hungry demon eating you alive. While watching Rengoku settle comfortably between your parted legs, you thought to yourself that it wasn't a dream at all. You licked your lips in satisfaction.

Keeping a steady and strong pace, the thick fingers of his moved in and out of your pussy; his thumb massaging your clit covered already in his thick saliva.

It wasn't long before the knot in your lower belly snapped and you screamed loudly. You watched him kneel while trying to catch your breath. There was nothing right about it.

"My darling flame, I was worried you would sleep through the fun," Kyojuro chuckled, pulling you closer by grabbing your legs.

Despite your surprise, you moved your hands up his chest, tracing the fiery mark in the middle. "My love… I can't believe you came to me."

He pushed his hard cock into you, earning a yelp from you, as he said, "I promised you that I would be with you till my last days. And I'll visit you every night."

Was it just your lustless mind playing tricks on you or did he feel bigger than before?

His hard thrusts easily made you whimper.

For him, every sound you made was like a melody, a melody he really missed; the idea of coming back to you was a good one.

Raising your hand, you said quietly, "Kyojuro..."

As he watched you, he raised an eyebrow, refusing to slow down; he used to do this when he was still a man. Kyojuro was shocked that you still wanted to do this despite everything that happened. A certain humor was apparent in the way humans acted, even a hint of pathetic sentiment. As he intertwined his fingers with yours, he mocked you, "You haven't changed at all." 

Squeezing his hands, you focused on the sensation of his cock fucking you deeply and nicely. Once again, you felt the familiar knot building in your lower belly.

Suddenly, he let go of your hand and his thumb started to roll and pinch your clitoris; it made your pussy clench rapidly around his shaft buried deep within you.

His hips moved shallowly as he grunted deeply to help you come down from your high.

 You expected him to fill you up, so much so that you pawed at his toned chest silently begging him for it. However, despite your silent pleas, he pulled his dick straight out and cummed all over your belly.

Watching him, you whined with sadness.

Kyojuro chuckled and leaned down. "You have to earn this," he said as he kissed you passionately.

It was hard to tell whether the events of the previous night were real when you awoke the next morning. The ache between your legs gave you the impression that this indeed occurred, but at the same time it made no sense. The point of thinking about it over and over was pointless, but you really hoped Kyojuro would come back.

Summary: Kyojuro ensures that you are completely satisfied during his yet another visit.

A/N: The prompt for today is: Knotting

A demon is an evil being. They are cold and uninterested. A demon's only source of joy is the torture of souls. They can, however, only operate where there is shame or anger, whether deserving or fictitious. When you curse, appeal to negativity, or seek vengeance, or truly intend cruel things to happen to others, the demon spirits will hear you from their den because your tone is a kind of their "dial tone."

Kyojuro became truly evil after transforming into a demon, his worst traits amplified by primal demon instincts.

However, the transformation in him did not end with his soul and heart. His outward appearance has also changed; his hair has grown longer, resembling a blazing fire, his formerly slender fingers have turned into sharp, reddened claws, and his eyes, once so understanding, were now clouded by an insatiable desire to kill and devour humans.

But one thing remained constant within him: his desire to possess you. Kyojuro realized that his feelings shared with you, back when he was a human, were too strong and grew too large to simply vanish within the raging fire of destruction within his soul. He was visiting you almost every night, as promised, devouring you and your body, which he craved ever so badly.

That night was no exception.

He didn't have problems crossing the threshold of your room; he usually used the half-opened window while summer was still in full swing.

Kyojuro slid into your bed like a snake, hovering over your sleeping form and looking down at you, his eyes gleaming with primal desire while slipping over every curve of yours.

"You seem to enjoy coming here every night," you said quietly as you opened your eyes to look at him.

You weren't dozing off. How could you possibly be sleeping? He came to see you every night, and you couldn't get enough of him. You didn't dare to tell anyone about what was going on. You wanted to protect him, despite being a Hashira. "It's good to see you again, my love," you said as you cupped his cheek.

Instead of responding, Kyojuro's lips brushed against the side of your neck as he inhaled your warm scent, which lingered all over his face. "I won't break the promise I made to you, little flame," his voice grunted in the darkness as his fiery eyes found yours.

"I'm sure you won't. My man of honor, you always keep your promises," you moved your hands into his hair while softly laughing. "I couldn't wait to see you once more."

His claws slid under your striped shirt and grazed your bare skin; the way your flesh felt in his paws tingled his senses, making him smirk. "Your mouth is golden, and so are your words, but could we skip the courtesy and get right to the point?" Kyojuro inquired as his left hand rested next to your head and his right began working on the string of your shorts.

"You get very impatient, love. I never expected to see you so desperate for me, should I be concerned that you've come here solely for my body?" You couldn't help but poke fun at him. It was always entertaining to play with his nerves.

Kyojuro didn't respond, instead he slipped his clawed hand inside your shorts and pressed on your clitoris; his claw soon slipped down your slit, teasing the entrance.

You gasped loudly as you bucked your hips slightly to receive more friction from him. You bit your lower lip while giggling at him. "You do become irritable."

When your words vanished into the room's silence, another sound followed - the sound of your shorts being ripped apart by the sharp claws.

You looked at him with an angry expression after letting out a surprised yelp. It was difficult to keep up with the number of clothes he ripped and destroyed since his first visit.

He quickly undid his belt and pushed his pants down, revealing his hard cock, which sprung free and proudly rested against his abdomen.

Your tiny palm barely encircled the impressive shaft, giving it a few strokes from tip to base. "Always prepared. Every night, you spoil me, love," you hushed before gently kissing his beck.

He quickly parted your legs and pushed into you, not waiting for you to adjust to his size. "So tight," he said, a smirk on his lips. "Your cunt was always so tight for me, and it is always dripping wet."

You wrapped your legs around his waist, drawing him closer and deeper. With a soft moan, you looked down between your bodies to admire the bulge in your lower belly that grew with each thrust. You clutched his arms, whimpering at the sweet sensation of his cock filling you up.

His demon senses drove him furiously into you; he felt divine being buried in your soft cunt and seriously considered slitting your throat with one of his sharp claws. Kyojuro was driven insane by the single through about you bleeding to death while being fucked by him; it made him pound into you faster; the entire bed rocked back and forth with each thrust.

One of your hands moved up his arm, reaching his neck and then his cheek. You smiled, cupping his cheek, and drew him into a deep kiss, oblivious to his sharp teeth.

During the kiss, he bit your lower lip, drawing blood from it. He began pounding harder and harder.

"Kyojuro, fuck!" You whined up to his lips. "Please. Please, make me yours. Please, I'm betting on you."

"I'll cum, I'll milk you with my seed, and you'll carry my child," he grumbled, his eyes glowed with desire.

"I will! Please, Kyojuro, believe me. I'll be yours, and I'll gladly carry your child," you promised, clutching his arm tightly.

He lifted one of your legs and rested it against his shoulder; the change in angle allowed his cock to penetrate you deeper. His dick soon began to throb.

Your back arched slightly as you yelled his name. Your own release could be felt building up in your lower belly.

The knot in Kyojuro's cock swollen when he spurted his cum in your pussy, making it impossible for him to withdraw his dick. "Fuck you, Y/N," he hissed into your ear, pushing deeper in to loosen his knot.

"Fuck me," you pleaded. As you reached your own climax, you moaned loudly. You wrapped your arms around him, hissing at the sensation of being so full.

His movements became sloppier. When the knot in his cock loosened, Kyojuro grunted and pulled his cock out; his semen slowly poured out of your abused hole.

You sighed sadly at the feeling of emptiness, but smiled softly at him. "There's still time before the inevitable sunrise. Would you like to cuddle?"

He measured you with his cold gaze as he gathered the last drop of his cum from the top of his cock; he put his claw into your mouth, so you could suck it clean. "If this is what you want, Y/N, my little flame."
