Chapter Text
The thing about taking care of a young Alpha was how quickly things could get out of hand.
Satoru had some experience with it, sure. How could he not, with a household full of Alphas (his sweet, sweet Tsumiki included), not to mention an entire school also populated by Alphas save for one or two. As the crusty old men who sat in the council kept saying, only Alphas could be jujutsu sorcerers worth anything. Utter bullshit, in Satoru’s opinion. Inumaki was one of the most skilful sorcerers his age, and he was an Omega. So was Yuuji, whose potential even the Six Eyes could not measure.
But to expand on his earlier point: Satoru did have plenty of experience when it came to handling Alphas. The fact that he was the most powerful among them no doubt counted for something, but all the same, he liked to think that he had certain flair with the young ones. Like knocking their heads together whenever they got too aggressive with each other, or throwing them to the deep end in the name of training and speedy growth.
That said, he did not usually take care of them in this capacity.
“Sensei,” Yuuta’s voice was low, the edges of his breathing rough, “can I do something else?”
Something else what, was what Satoru would like to know. In the past hour alone, this kid had not only fucked him to tears, knot and all, him being a teenager meaning that he could still pop one anytime anywhere; but then he had also wrapped his lips around Satoru’s cock and proceeded to suck him so enthusiastically that Satoru had very little choice but to come down his throat, pussy clenching and leaking around three determined fingers. And now he still wanted something else?
Never in a million years would Gojo Satoru have thought, when he had first decided to help his cute precious student dealing with the fallout of a sudden presentation, that he would end up here, a feast to an insatiable puppy.
It had begun as a logical solution to an urgent problem. No one had expected Okkotsu Yuuta, Special-Grade-turned-Grade-4-turned-Special-Grade-sorcerer-again, to suddenly present as an Alpha at the age of seventeen. Most presentations happened at thirteen, fifteen at the latest. Everyone had pretty much accepted him as a Beta, and then, suddenly, he was not.
Satoru had a whole theory involving Rika and how her existence as a cursed spirit might have affected her beloved Yuuta's presentation, but it was neither here nor there. What happened had happened. Now, to deal with the aftermath, which was a first rut at seventeen, and a first rut at seventeen was nothing like a first rut at thirteen. Satoru still remembered his own—he had been twelve, which was not quite unheard-of but certainly early—and that had been terrible enough despite all the careful preparations, in a controlled environment no less, with all the old wisdom and resources of the Gojo Clan available to him.
Okkotsu Yuuta, Special Grade sorcerer possessing an absurdly high amount of cursed energy and experiencing his first rut at seventeen, would have flattened the entire mountain, let alone the ancient school complex, had Gojo Satoru not been there to run damage control (read: help him with his rut, which had turned out to be the only solution to the problem. Had Satoru backed out? Of course not.)
That had been two weeks ago. And now, here he was, spread on his hotel bed and still running damage control because it would take time for a newly presented Alpha or Omega to adjust to all the changes happening in their body. Which meant that, yes, he would have to take Yuuta along on his missions until things settled down somewhat.
Not that this wasn’t an excellent training opportunity, all things considered—or so the Great Teacher Gojo kept telling himself.
“Can I?” Yuuta asked again in the absence of his reply, raising his face from between Satoru’s thighs, eyes big and pleading. One day in the future, Satoru would make a decision based on those eyes and he would regret it for the rest of his life—if he hadn’t already. Right now, however, he couldn't help but reach down, stroking his student’s face with shaky fingers, stomach twisting when Yuuta closed his eyes and leaned into Satoru’s touch.
“Greedy little thing, aren’t you?” he murmured, relieved that his voice, at least, sounded more or less like usual.
Yuuta was smiling and rubbing his cheek into Satoru’s palm. “It’s what you taught us. Never waste any opportunity.”
Satoru raised his eyebrows at that. “So you were listening after all.”
“I always listen to you, Sensei.” This was followed by a delicate kiss and a wet lick on the inside of his wrist. Satoru felt his hand twitch.
“Does that mean that you’ll listen to me too if I tell you to stop?”
“Of course,” Yuuta said this like it was a law written in the stars, but even as he did so, his fingers started stroking the soft, sensitive skin of the inside of Satoru’s thigh. “But you’ll give me at least one chance to present my argument, won’t you?”
That made Satoru laugh. “Brat,” he said fondly. “Trying to negotiate with your teacher.”
“So, can I?” Yuuta asked softly, his expression still sweetly innocent despite the obvious direction his fingers were heading. “Can I make you come like this, Sensei?”
To be fair, the boy did ask. He did not, however, wait for Satoru’s answer before spreading Satoru’s thighs and licking into his pussy.
Satoru was pretty sure he screamed, or at least made a noise of some kind. What was mostly surprise at first turned into soft little ah ah ah’s when he felt Yuuta’s tongue plunging deep, licking into every part of his cunt as if he wanted to taste him everywhere. All ambition and absolutely zero finesse; Satoru felt a faint wave of irritation at that—what a reflection on one’s teaching—but then again, he wasn’t much a fan of finesse himself. Finesse was overrated, and when Yuuta used one of his thumbs to zero in on his clit and start playing with it, he realised that no, his teaching hadn’t been lacking at all.
“Yuuta,” he gasped, “ohh, Yuu-ta…”
There was an answering groan, vibrating directly into his cunt. Satoru threw his head back and moaned, losing himself in the sensation. Not every Alpha wanted to have their pussy touched, let alone played with. In fact, most Alphas would consider the action humiliating. Satoru never really had such qualms, but then again, he was Gojo Satoru. Besides, not everyone had a student who was only too willing to put his face between his teacher’s legs and eat him out so enthusiastically either, so there.
A student who looked at him with blue eyes so dark they were almost black and said, all sweet and polite, “You’re close, aren’t you, Sensei?”
This little shit was as far as Satoru could think, because then he felt a hand under his hips, lifting him slightly and angling him in such a way that Yuuta’s tongue could fuck him even deeper, where he was all hot and slick like an Omega. And then his fingers, oh his fingers, rubbing and pinching his clit until Satoru had no choice but to come, rippling and clenching around that ambitious tongue.
Definitely overrated, finesse.
“Sensei,” Yuuta was murmuring softly, pressing kisses on his shoulder and neck. Satoru could feel a deep throb inside his pussy at that gentle adoring voice, and thought, shit. If that’s how he was going to react every time Yuuta called him ‘sensei’, they were going to have problems.
“You’re crazy,” he declared, hating how weak and unsteady he sounded.
He could feel the shape of Yuuta’s smile against his collarbone. “Didn’t you say that one had to be a little crazy to be a jujutsu sorcerer?”
Satoru cracked open an eye and threw a baleful look at his incorrigible student. “Yeah, sure, go ahead. Turn everything I said against me.”
“I’d never dare,” was the meek answer. What wasn’t meek was the sudden but unmistakable press of a hard cock between the puffy lips of his cunt. Satoru recoiled, hissing, unable to bear any sort of stimulation right now and especially not there.
“I’m sorry, Sensei, ah, sorry,” Yuuta tried to assure him between gasps. “Please relax– I’m, mmh, not doing anything–”
“Like hell you’re not–”
“I can wait, I promise I–”
Satoru choked on his laugh. “You can wait,” he wheezed, for once not even caring how shaky he sounded. “Right.”
“Yes,” Yuuta insisted, and there, something in his voice finally got through him. Satoru stopped laughing and stared at his student. This was the boy who hadn’t been able to stop fucking him two weeks ago, who hadn’t known what to do with his knot, who had cried when he thought he was hurting his beloved teacher. And now, here he was, hovering above him, looking so earnest and yet at the same time so much in pain, and still saying ridiculous things like, “I can wait. Forever, if I have to.”
Shit. Satoru wanted to cry.
You just want him to be your dog, was what they had accused him when they had seen what kind of influence he held over his Special Grade student. During moments like this, with Yuuta looking at him like this, Satoru could not even deny the accusation with any sort of conviction.
“Forever?” he hummed.
Yuuta nodded, jaw clenched. “Forever.”
“Bullshit,” Satoru declared, hooking a leg around his student’s waist to press their hips together. Yuuta shouted, trembling, his cock pulsing on Satoru’s cunt. “What is this if not one of your ‘arguments’?”
Yuuta’s face was all red and he was still gasping, wrestling with the obvious temptation to just fuck into his teacher, but then he grinned. “Well, only if you’ll allow me to present, ah, it. My argument, I mean.”
“Really,” Satoru said drily, “are you that obedient?”
“Yes.” Yuuta buried his face in Satoru’s neck. He was shaking and his breathing came out as tiny desperate whines, but his hips remained still. “You know I’ll always listen to you, Sensei. Sensei. Sensei.”
Satoru’s heart just plain melted. He was so weak for things like this. Perhaps those old men had a point after all. He did want Yuuta to be his.
“Go ahead, then, puppy,” he said with an exaggerated sigh and spread his legs open. “Convince me.”
His best student didn’t need to be told twice.
