"What do you need, Ajax?" Mr. Alberich smiled and greeted Ajax after he visited him after the day was done. "Professor Tsarevich is not here, he went on home, so if you need anything from him, it is best that you come get it on Monday."

The man held a flute in his hands, a charcoal-colored one. Venti's.

Ajax burned with jealousy at the thought of Venti spending time alone with Mr. Alberich. It was an irrational thought, yes, but the ginger wanted the hunk of a man to himself. But who was he kidding? It's probably not a big deal... right?

"I have a problem with a certain place in a piece. I picked it up from a couple friends down at Raiden. It looked interesting."

"Sure, come on in, I'm just repairing a student's flute, so sit tight for a minute."

Venti was already sitting inside, fiddling with a piccolo. His tiny face beamed when he saw him. "Hello, Ajax! Didn't expect to see you here."

The ginger waved at the twink, who started to play a march with the goddamned screech-producer. He sounded good, for sure, but it was still a high-pitched menace.

"Venti," Mr. Alberich interrupted, "May I?" He gestured the flute at the boy, as if asking permission to play on it. Venti consented.

The man put the headjoint to his lips and started to play that same march. This time, just as beautifully as the original himself. The sitting boy joined in, happily. Ajax enjoyed the tune, watching them in amusement. Sure he was cursing out Venti in his head, but they were so talented.

A knock came from the door and a head popped in. It was a man with brown hair and honey-colored eyes. The student teacher looked at the door and nodded at the stranger. The stranger walked in and stood next to Ajax, musing at the duo. They finally finished the excerpt, leaving the tawny-haired student in the air, missing the sound.

The new guy started to clap for them. "Beautiful. I expected nothing less from you and your students, Kaeya."

"Many thanks, Zhongli." Mr. Alberich chuckled. "Can you wait a few more minutes? I've just repaired one student's flute, then I have to look over a new piece with another."

"Doesn't sound like a few minutes to me..." smirked Zhongli. "Take your time, I'll be in the car."

The assistant nodded as the man left. Ajax looked at the guy leaving the room and never took his eyes off him until he was out of sight. Fuck, he was hot, too. Was this the guy Mr. Alberich hits it off with? If so, then he had no chance. Not one.

"Do you have to go? I can come back tomorrow." Ajax announced.

The bluenet shook his head. "No, he can wait. My students come first." He gave Venti his black flute back and the twink excitedly packed it up along with the piccolo. "There were only a couple missing pads, so I replaced them just fine. And don't worry, you weren't fingering the notes wrong."

Ajax coughed when he heard the word 'fingering.'

"Thank you so much, Mr. Alberich! I'll see you tomorrow. Have a good evening!"

Venti took his woodwinds and pranced out the room.

"Now. Show me this piece."

Ajax dug into his backpack and took out a folder, pulling out the sheet music and handing it to the student teacher. "It's Broadway," he says, pursing his lips.

Mr. Alberich looked interested in the piece, too. He flipped through the pages and nodded, satisfied. "Of course it is, everyone knows it. How did you find such a good trombone arrangement? I cannot find a name on this paper."

"My friends did. They wanted low brass to finally have a feature in such an iconic song. They'll be performing it at their recitals."

"Are you part of that group?"

The carrothead sighed. "I wish, but I can't perform at Raiden if I don't attend it. I can get special permission but that's only if I was like... a celebrity. Plus, this was an extra copy and they wanted me to have it."

The assistant smiled. "Brilliant. Let me hear you sight read it."

"Oh no, no, no. I tried and failed."

"Maybe you'll be better today. Give it a whirl one more time."

Ajax knelt down to his case and assembled his trombone. Mr. Alberich laid the music out on the podium and gestured for Ajax to stand in front of it and start reading.

He did great the first few chunks of the piece, but when he reached his problem spot, he ran into it head-first and messed up.

"Mhm." Hummed the student teacher. "Sixteenth notes for low brass are a pain in the ass, I know, but you got the right idea. Good Job."

"Thanks, sir."

"What I want you to do is double tongue."

Ajax sighed then laughed. "Bro, I suck at that. I can't. No."

Mr. Alberich smiled. "Wouldn't hurt to practice, now would it? Here's an exercise." He pulled out his trumpet mouthpiece and demonstrated. "Remember, use the tip of your tongue and the back."

The man double-tongued on his mouthpiece, creating a monotone quacking noise in multiple sixteenth notes. All Ajax did was shake his head and keep snickering under the excuse that he simply couldn't do it. He tried, but ended up blurting random notes from laughing into his instrument. In reality, the ginger enjoyed watching the assistant tongue on the piece of metal. It looked so lewd . He couldn't think of anything else other than double tonguing Mr. Alberich's asshole. He couldn't stop wishing that the man's lips be on his own instead of the mouthpiece.

"Okay, okay, I'll be serious."

"I know it's wonky, but you got it."

Ajax tried again. He successfully played a whole measure sixteenths until he hit a roadblock and fucked up his motion. Mr. Alberich threw his thumbs up.

"Hey I did it!"

The student teacher laughed and clapped for him. "Now let's play actual notes. Play your B flat scale, double-tonguing each time. One beat, one note." He started snapping a moderate tempo for Ajax to play to. "First position."

The ginger flinched because of the intrusive thoughts that flooded his mind when the man said 'first position.' He needed fucking holy water.

Ajax found himself on his dormitory bed, rubbing one out once again. He was tired of feeling lonely, with no cockwarmer to keep him company. Aether was at another girl's dorm, so he had the place for himself for the night. He needed to get over Mr. Alberich, but he absolutely cannot bring himself to. The man was stern yet gentle, adorable yet so undeniably sexy- looming over his brain like a parasite gnawing away at his consciousness. Precum leaked from Ajax's head as he teased himself at the thought of the assistant sucking on his cock, tonguing it as if it were that very mouthpiece of the trumpet he was keen on playing.

He wanted to grab the bluenet's midnight locks and facefuck him until his throat was bruised, begging him to stop, ejaculating his warmth into his mouth. Ajax let out a groan. How did he like his sex? How does his boyfriend Zhongli fuck him? Did he like it hard? Ajax can go hard. Or did he like it soft? Too bad, Ajax loved rough sex.

The ginger could feel himself nearing an orgasm, locking his hips in strained movements as he pumped long streams of white onto his bedsheets.

Shit.

He had to clean that crap up before Aether comes in and sees it.

Mr. Alberich wasn't at the podium when Ajax entered the room. It had been a smooth week of practicing the Broadway piece, getting better at playing the straight sixteenth notes, occasionally asking the student teacher for some help or the student teacher asking Ajax about his progress. But... Mr. Alberich wasn't there. What happened to him? Was he sick?

Professor Tsarevich walked into the classroom and waited at the podium for more students to flood in. The tawny-haired boy assembled his trombone and snuck out one of the doors to see if Mr. Alberich was actually around or absent.

Ajax wandered outside the building, suddenly hearing muffled sniffles and dialogue from around the corner. He took a peek at the turn then raised his eyebrows at a shocking sight.

The assistant was squatting against the wall, on the phone, crying. He spoke into the phone in a low, shaky, and strained voice.

"Baby, please. Can we talk about it later? I have a class in five minutes and I cannot process this right now, please can we just discuss it over dinner?" He pinched the bridge of his nose and waited for the response from the other line. "No... maybe you need the day to think about it... you already did? Please let's talk because what did I do wrong? Can I see you at the end of the day again... Please? Please Zhongli, please... "

Ajax started to feel bad for the guy. He started to sob even more when he looked at his phone to see that the other end hung up. He desperately tried to wipe away his tears by wiping them on a handkerchief he had in his pocket. The man looked to the side while dabbing the corner of his eye and saw the carrothead peering from the corner.

The peeping tom got startled when he got caught and hid behind the wall.

"Ajax."

The ginger popped up again. "Yes, sir? Are you alright, sir?"

"I appreciate your worry. But please do not listen in on things so sensitive." The student teacher stood up and walked towards him. He looked down and wiped his eyes some more, Ajax noticing that the bandage that he always had on his right eye was not there anymore. He looked at the student, covering that eye. "Allow me to replace my patch. You should get going."

The man started to walk away as Ajax quickly apologized. "I'm sorry for intruding, Mr. Alberich!"

"Don't worry about it, Ajax. Get to class."

Professor Tsarevich stood lazily looking over the class, perhaps wondering where his student conductor went. He noticed Ajax slowly walk in amidst the instrument-playing chaos that whirred inside. The guy nodded and marked the ginger present. It may have been wrong to feel happy that his stupid crush was finally breaking up- but he was. He may have a chance.

A few minutes later of Mr. Do-Nothing doing nothing, Mr. Alberich proudly walked inside the room and smiled at the students.

"I apologize, my humble musicians, but the admissions office called me and had the audacity to say I did not check in," he chuckles along with the rest of the class. "Well, I showed them that I was alive and well while they double checked."

The conductor continued to direct the class while the actual director disappeared after talking into the man's ear for the thousandth time this year, leaving him alone to teach the class by himself again. Were they instructions? Insults?

The main thing was that Mr. Alberich looked like he wasn't bawling his eyes out just a few minutes ago. He looked... fine.

After rehearsal, Mr. Alberich picked up a wad of papers and called Ajax over to the music room's library.

"Mr. Alberich... if this was about earlier, I'm sorry I was snooping, I was just wondering where you went."

The assistant didn't say a word, but instead opened the door to the library and gestured to the other to take a step inside. The library was full of music that spanned from the Baroque era to now, the Modern era. There were shelves and shelves of folders with white and faded yellow sheets, metal filing cabinets, and wooden cupboards for the storage of extra instrument compartments. He joined the ginger inside and closed the door behind him. He walked over to a filing cabinet, opened it and filed the papers he held away. He then leaned on it and crossed his arms over his chest. The man looked pissed .

Ajax burned up. Mr. Alberich's eye stared him down with a brow furrowed. If he thought that the guy was sexy when he smiled, he was even sexier when he was serious. His heart pounded in his chest.

"You should have minded your own business."

"I know-"

"Then why did you listen? You made a conscious decision to stay."

The ginger opened his mouth, "Mr. Al-"

"Ajax! I am deeply disappointed with you. I made it clear that you see me as a mentor and not a mate. You stayed because you wanted to hear about my personal life, no?" The bluenet ran a hand through his hair. He was unfortunately correct. "There are implicit boundaries that you have to figure out, and you just crossed one. What do you have to say for yourself?"

"There can be no excuse..." Ajax looked at him with remorseful eyes hiding his animalistic desires, acting innocent in order to later leap at his prey. Mr. Alberich nodded and sighed.

"For the love of God, don't do it ag-" The blueberry-head was abruptly cut off by an aggressive mouth forcing itself onto his. Ajax pulled him closer by tugging on his open collar, licking his lips and shoving a tongue inside. He then pinned the bluenet on the filing cabinet with a thud. The man started to try and push the ginger off of him, but the latter persisted, getting deeper and hungrier with the kiss.

Mr. Alberich couldn't breathe, moaning into Ajax's mouth in protest of his situation. "Ajax... Ajax!"

His hands started to wander inside the assistant's shirt, feeling his skin and muscles, circling over his nipples, pinching them. He grinded his erection on his groin. He pulled away from the sloppy kiss, still fondling with the man's tits. "Oh Kaeya, you taste so good."

Kaeya gasped for air and started to pound a fist on Ajax's chest. "Ajax, stop," he croaked between breaths, "Stop, not here!" Ajax halted and looked at the man disheveled in front of him. "There's another class in thirty minutes."

"We have time."

The ginger went straight to the man's neck, biting and sucking on his flesh. His smooth skin felt like a dream on his lips. Kaeya ruffled Ajax's hair, whimpering from the depths of his throat. Ajax started to unbutton the godforsaken blue dress shirt that the assistant wore, leaving trails of kisses from his collarbone down to where his trousers blocked the path.

Ajax kept his hands on the conductor's waist, turning him around and bending him over so he could have easy access to his ass. The boy slapped it once, earning a sexy sound of surprise. His hands moved to undo the zipper and pull down his pants. Kaeya shuddered from the cold air touching his bum, and not too long after, Ajax's fingers teasing the rim of his asshole.

Kaeya let out labored breaths, stifling sounds that could emit and reveal the dirty act. He desperately did not want to get caught while Ajax could care less about the surroundings, for the chance of getting ratted out made him hornier. The ginger licked his fingers and lathered it thick of his own saliva and inserted two of them inside the bluenet. Kaeya helplessly grabbed the handles of the cabinets to stabilize himself as Ajax used his other hand to stroke the conductor's hardened dick. He let out a moan.

Ajax bent over Kaeya's form, warming him with his body, whispering in his ear. "Bad boy. Do you want us to get caught?"

"No," Kaeya whimpered.

"Look at you, melting at my touch. And what happened to mentor over mate?" He smirked and nibbled on his ear. "Hypocritical, don't you think? Why don't I teach you the lesson this time?"

Ajax unbuckled his belt and whipped Kaeya's asscheek with it. The bluenet cried out, so he whipped him again. "What did I say?" The man stayed quiet, breathing heavily, almost falling to his knees. The ginger unzipped his pants and pulled out his cock, pressing it onto Kaeya's entrance, teasing him with his head, precum dripping. "You're so sexy when you're desperate."

He inserted his head, "This, Kaeya, is first position."

Kaeya was trembling, wanting more than just being teased. "Ajax-"

"If you keep being a whore, you might just experience seventh position. Hell, why not, now?" Ajax slammed his cock inside of Kaeya as he yelled in pain, making Ajax yank his hair. "Shut the fuck up, you useless bitch."

Kaeya panted heavily, moaning once in a while so he could get punished and called names. Zhongli would always insult him whenever they had sex, and he never knew that it could make him feel so excited . He could feel his hole getting stretched, Ajax struggling to be let through.

He then felt Ajax's cock start to hit a spot so tender, it made the bluenet go crazy. He moaned louder, forgetting the setting they were in for a hot minute.

"Hm? Do you like that? Look at you, swallowing me up. Took you a while to get to seventh, huh," Ajax started to play with the man's nipples again. "It's flattering that you want to sing for me, but if we get caught, it'll be all on you."

Kaeya folded at the threat, knees feeling like jelly as the ginger kept relentlessly massaging his prostate with each thrust. Bursts of sexual pleasure enveloped his poor heart and mind. Still grabbing the cabinet handle with all his might, he brought his other hand to cover his mouth. The sound of muffled whines, skin slapping on skin, and squelching fluid was worrying the man. He might be discovered but the sex.... The sex felt so goddamn good .

Ajax tugged Kaeya's hair once more before cumming inside him.

He pulled out as they collapsed on the floor, the ginger catching the bluenet in his arms, both catching their breaths. Ajax noticed that Kaeya hadn't had his orgasm yet, so he grabbed his dick and started to stroke his shaft.

The conductor arched his back onto the student; overstimulation felt like a jolt through his body, almost convulsing and he was brought to ejaculate a stream of white on the filing cabinets.

"Look at the mess you made, you dirty little slut."
