low self esteem (that certainly wont do) by PhoenixTheKaiju

Summary
“I’m sorry,” Kaigaku apologizes. What for? He doesn’t know. “I didn’t know they said that about you.”
“We hang out all the time, Kai,” Gyutaro takes a step forward. “How could you not; haven’t I told you?”
Kaigaku is praying to the Gods that Gyutaro can’t hear his heart beating. He doesn’t know if the room is stuffy and hot because of the steam still settling from the shower, or if it’s because the most attractive man, in his opinion, is standing right in front of him, inches from his face.
Kaigaku believes he's ugly; Gyutaro shows him the opposite.

Summary
“Shinazugawa—”
“I’m good, thanks. Have a wonderful night, ladies.” He shuts the door and exits the room where Giyuu stands outside completely unamused. If it weren’t for the fact that they were both still in their workplace, he would have taken things into his own hands and fucked Sanemi against the closest wall right in front of those girls.
Giyuu reminds Sanemi who he's marrying.

Summary
“Mhm,” Enmu hums, “Um, what did you need me for?”
“Well, apart from the files, I wanted to talk to you.” Muzan gestures to the seat in front of his desk. “Come, sit.”
“Yes, sir.” Enmu obliges, taking his seat in the chair across from his boss's desk and before the taller-by-four-inches man gets the chance to sit down, Enmu’s already imagining them fucking on top of the wooden furniture, pushing away all the papers as his ass is set on the cold surface while his thighs are spread open.
Enmu has eyes for his boss, and Muzan knows just how to give his favorite coworker a promotion.

Summary
“You’re not supposed to be on your phone, Uzui.” Giyuu scolds him gently. He had always been a sucker for following the school rules, specifically dress code, yelling at Tanjiro for wearing earrings or beating Zenitsu with a newspaper and telling him to dye his hair yellow.
“Relax, Tomioka, I’ve got it open to the school email anyway.”
Giyuu sighs, “What does the new announcement say?”
Tengen clears his throat, imitating Amane’s soothing voice and reading the message out loud: “Attention teachers and staff, we will have a new Math teacher by the name of Sanemi Shinazugawa arriving next week on Monday so please help him get situated when he arrives.
Sincerely, Amane Ubuyashiki.”
The new math teacher at Kimetsu Academy is smoking hot, and Giyuu does his best to get his undivided attention.

Summary
“You’re getting turned on by this, aren’t you?” The sudden gasp that comes from Sanemi’s (his) mouth as he palms his hardened cock through his fundoshi answers the question for him. “Look at you. So pliant. Are you as loud and brash in bed as you are normally? Or are you quiet, taking what’s given to you like a good boy?”
“Fuck you, Tomioka,” Shinazugawa grumbles weakly.
Giyuu smirks.
“If you insist.”
A Blood Demon Art swaps Sanemi and Giyuu's bodies.

Summary
Giyuu blinks. Wow. Their stories parallel each other, riding on the same axis but bound to never intersect as they chase people who feel like they’re constantly running away.
But here Sanemi stands, so close, and he feels the sounds of a confession bubbling on the tip of his tongue, but he closes his mouth before he ruins their entire relationship.
“You know,” Sanemi turns to face Giyuu as he hums in acknowledgement. “It would be great if he knew how I felt.”
“Then why don’t you tell him?” Giyuu leans on the edge of the tub.
“Well, he’s sitting right next to me.”
Sanemi and Giyuu get steamy in a hotub.

Summary
Just then, the doors are swung open behind them again as the sudden younger Princess--and Giyuu’s prospective wife enters the room with two other people in tow. One of them a girl with unnaturally pink braids and bright green eyes and the other--
Oh my.
Hello sailor.
A man with striking white hair waltzes into the room behind the pink-haired girl and the smaller with the purple butterfly clip, his face covered in scars and eyes the color of the finest sugilite. His hair framed his face with two fluffy bangs running over the bridge of his nose and drooping down the left side of his face, and his attire was unbuttoned at the chest, exposing the unusual x-marking scar across his pecs.
And just like that, Giyuu was entranced.
Giyuu and Sanemi find themselves falling outside of their marriages and into each other.

Summary
Truth be told, in his fantasies, Giyuu would let Sanemi do anything to him. He’d let him bend him over, fuck him stupid and milk him dry. But in the real world? The prospect of doing anything as ludicrous as that was simply terrifying. If Sanemi knew of the fantasies he had kept locked away inside his head, he might actually combust into a pile of ashes and die.
“Giyuu, open the door.”
After a tussle with a demon, a Blood Demon Art induces Giyuu's heat.

“I didn’t know you’d be so muscled—” He breathes out through a kiss, “You don’t look the type.”
“Have you been staring at me?” Tomioka questions, palming his dick through his uniform pants. Sanemi decides he needs them off now.
Undoing his belt and kicking off his pants and fundoshi, he replies, “No.”
Sanemi's got his head up his ass. Giyuu teaches him a lesson.

Summary
He’d taken a shower at the end of the hall with their shared bathroom and came back to his room to check his phone, only to find a notification from Instagram saying that someone had liked his photo.
It was completely normal. People liked his Instagram photos all the time, especially with how good-looking he was.
Except for the fact that the username was most definitely Obanai’s.
Obanai and Tengen are roommates. You'll never guess what happens next!

“I know,” Tengen grumbles. He scrutinizes the girls, and promptly flips his switch when Shinobu tries grabbing his arm and leading him away. “Fuck.”
Tengen stands up abruptly, leaving his beer forgotten at the table and shakes when he leaves, storming over to his boyfriend. Shinazugawa jumps, muttering a “jesus” under his breath as he turns away.
“Someone’s jealous.” Giyuu quips.
“No shit.” Sanemi huffs, “He’s gonna blow his fuse.”
“I think he already has.”

Summary
His birthday isn’t anything significant like Lady Furina’s is, the one day of the year where mostly everyone gets time off, unless you’re, say, the Chief Justice or the Duke of the Fortress of Meropide where the walls never sleep. Although apparently, Neuvillette has deemed his birthday more important than that of his (former) Archon’s.
“I would like to treat you today. Would you like to go out for breakfast, or should I make something?”
Being in the public eye isn’t exactly Wriothesley’s forte. He’s more experienced with laying low, hence the nickname Lord Incognito. But nobody really recognizes him anyway, and it’s not every birthday he gets to experience this.
Neuvillette treats Wriothesley for his birthday.

Summary
He hates these kinds of conversations. They drag his attention away from, to put it meekly, more important things, and they’re also all fruitless. Haven’t the masses heard of his mass rejection? Is it not clear the reason why after five-hundred years, he still remains impartial? It’s been the same way for, specifically, the last three centuries; carefully turning away suitors he has no interest in wedding, and none of them he’s even considered for a short tryst out in the bushes; a dangerous sight that would be: to see Fontaine’s esteemed Iudex fucking some nameless noble from the Court, destroying all of his modesty and decorum. And his reputation.
Preposterous.
Neuvillette and Wriothesley must keep up appearances in the Court.Series

Summary
The other man stands up and heads over to the window, making a show of placing his hands on the shelf that sits under the window, bending over just enough to show off his ass.
He knows what he’s doing.
“I must confess I have ulterior motives.” Neuvillette says, and wow, that is a first. Wriothesley honestly thought he’d be the one luring Neuvillette into his filthy trap. “While it is true the weather has been particularly warm out, it has never been too much for me to handle.”
Wriothesley sees Neuvillette for a "work" meeting.

Summary
As he washes the dishes, his hand touches some stray piece of food and he flinches so much, water splashes on the floor. Wriothesley groans loudly, highly exasperated and is one bad move away from flipping his shit.
He needs a shower. To relax under the hot spray of steam, or maybe he just needs Neuvillette.
Wriothesley de-stresses with Neuvillette in the shower.

He is a vision. Strong, tanned muscle is exposed on his arms, but the lingerie he wears bare is a sleek lacy black that hides barely anything, if nothing at all. Neuvillette has just walked through the door of the bedroom and all rational thought loses his mind as he sees the incredible man in front of him.
Wriothesley is exquisite.
For his birthday, Wriothesley prepares something extra-special to cheer Neuvillette up.

Summary
“‘M fine.” Sanemi shrugs, finally blinking and turning away from his distasteful reflection in the mirror. “Just thinking.”
“About what?” Giyuu asks, his hair swishing as he turns to step in front of Sanemi.
“Nothing.” He lies. “Work.” He supplies instead. Giyuu fixes him with a raised eyebrow that says he’s calling bullshit.
Sanemi has doubts about his physical appearance. Giyuu comes to make it right.
