But they say everything you learn eventually becomes useful someday.
Tae-hoon swallowed dryly as he desperately tried to recall the obscene lessons from the training he’d received. Unfortunately, however, the old saying that theory and practice are different applied to sex too.
He’d impulsively dropped to his knees, but the moment he lowered the zipper and took it out, his confidence instantly hit rock bottom. Just lightly holding the man’s cock in his hand was enough to make it slowly harden, and even his spirit shrank back.
In the end, after hesitating and dragging out the moment, Tae-hoon eventually stole a glance at his Esper.
In a way, it was quite a cunning choice.
Pulling back now and admitting he couldn’t do it would definitely be embarrassing and humiliating, but he could only do so because he was certain Gwan-young wouldn’t reproach him for it.
But Tae-hoon soon deeply regretted looking.
Honestly, it would’ve been better not to know.
A man more violent and uncontrollable than anyone else in the world was now covering his eyes with his arm just because of one thing Tae-hoon had said, clenching his fists tightly.
That really was something better left unseen.
‘At this rate, I can’t even say I can’t do it.’
Tae-hoon swallowed a sigh.
Meanwhile, Ji Gwan-young himself was in no state to spare even the slightest composure.
For someone whose thoughts and outward actions almost never matched, this was extremely rare. But in front of his one and only Guide, he couldn’t help it.
This was Choi Tae-hoon—a man who’d never even dared hope for a kiss initiated first. And now that same Pair was kneeling before him, teasing his sensitive skin with hot breaths.
Pretending to stay calm in that situation?
For Ji Gwan-young, that belonged in the category of things absolutely impossible.
After well over a month without contact, any touch whatsoever became stimulation powerful enough to shake an Esper’s entire senses.
In some ways, this was even more intense than the first time they’d held hands at the fan signing event.
Every cell in his body that remembered what it felt like to touch Choi Tae-hoon screamed for attention, and something closer to instinct than the desire he’d barely managed to suppress for months flipped a switch in his mind.
Fortunately, Tae-hoon didn’t torment his Pair for long.
“…Hng…”
A faint groan slipped from Ji Gwan-young’s lips.
Truthfully, Choi Tae-hoon’s fellatio was far too clumsy to really be called pleasurable.
Unable to even properly use his tongue, all he did was earnestly suck him off with the same sincerity that defined his personality. It was movement so awkward the term oral “sex” hardly suited it.
But despite the clumsy stimulation, heat surged through Gwan-young so intensely it shocked even him.
Because every time his hardened cock nudged the back of Tae-hoon’s throat, the man would cough softly yet still scrape the tip with his tongue, trying his best to draw out his pleasure.
In the end, Gwan-young couldn’t keep his promise for very long.
Choi Tae-hoon was the man who’d loudly insisted he would never become gay even if he died. Yet now that same man sat between his legs diligently sucking his cock.
It was a sight both incredibly entertaining and somehow adorable at the same time.
“I told you not to open your eyes…”
“It’d be a waste not to look at this.”
Right. You said this was a ‘relationship out of necessity.’
Ji Gwan-young overlapped the image of the past Choi Tae-hoon—red-faced and shouting furiously at him—with the man now kneeling before him, eyes narrowed and trembling as he took his cock into his mouth.
A low laugh escaped him.
As he stroked the head bowed earnestly between his thighs, Tae-hoon’s lowered brows trembled faintly.
“You said you’d never become gay.”
At the teasing remark, Choi Tae-hoon pulled the cock from his mouth and protested indignantly.
“I’m not gay!”
“Then what exactly is this?”
Gwan-young’s hand slid down from Tae-hoon’s warm hair along the line of his flushed cheek.
The sight of Tae-hoon red all the way down his neck contained not even the slightest hint of rejection toward what they were doing.
And honestly, Tae-hoon himself was beginning to feel awkwardly embarrassed by the fact that the same person who’d once shouted so confidently now seemed to have completely lost any aversion to relationships with another man. No, more precisely, to sex with Ji Gwan-young.
In truth, Gwan-young’s teasing had simply been consideration for Tae-hoon, who was trembling while still stubbornly pushing the cock deep into his throat and sucking hard enough to hollow his cheeks.
He wanted him to rest.
But as always, his words had been too well disguised beneath his characteristic way of speaking, making his true intentions difficult to notice immediately.
Ji Gwan-young could see right through Tae-hoon’s shrinking thoughts.
In the end, he smiled bitterly and pulled Tae-hoon up from where he knelt before him.
Immediately, Tae-hoon opened his mouth cautiously, his face transparent as glass.
“…Um, you still haven’t… finished…?”
“I prefer coming inside you over finishing in your mouth.”
“…..”
Every time Ji Gwan-young spoke this bluntly, Choi Tae-hoon acutely felt the experience that came with the six years the older man had lived beyond him.
He had absolutely no comeback.
Face burning red, Tae-hoon merely fiddled with the buttons of his shirt.
For a moment, the “how to open yourself alone” lesson from training resurfaced in his mind. But the person who’d just casually said something so shameless chose not to strip Tae-hoon’s clothes off.
Instead, he pulled him close and buried his face against him.
Tae-hoon spoke hesitantly.
“Gwan-young-ssi.”
“…Mm.”
“Do you have time tomorrow too?”
A slightly hoarse voice flowed from Gwan-young’s lips.
“I do.”
Watching Ji Gwan-young visibly grow languid, Tae-hoon suddenly felt strangely hot inside.
The person now relaxing in his arms with eyes closed was an Esper powerful enough to toy not only with the people of The Center but even with ministers.
Tae-hoon mentally traced through all the grand words used to describe his Esper before carefully lifting a hand.
His eyes had landed on the smooth, glossy hair. But that was as far as he got.
Unable to even dare touch his Pair, Tae-hoon hesitated for a long time.
Because Ji Gwan-young was so prideful by nature, he worried he might somehow dislike it. But of all the worries Choi Tae-hoon had today, this was by far the most unnecessary.
The moment the Guide’s hand touched his head, the Esper’s half-open eyes slowly drifted shut again, loosened somewhere between pleasure and bliss.
…Wow.
Watching the monster completely let down his guard, Tae-hoon unconsciously swallowed dryly.
Seeing a man who normally resembled a ticking time bomb become utterly defenseless from the touch of his fingertips alone created an indescribably strange feeling that sent chills down the back of his neck.
Even the voice he barely managed to continue sounded cracked and shaky.
“Then… tomorrow maybe we could go outside together.”
“Where do you want to go?”
“Just… outside. A movie theater, a restaurant, a café. Even just a walk.”
Somehow, every single suggestion Tae-hoon made was something nearly impossible for a celebrity so famous it would be harder to find someone who didn’t know him.
With dazed eyes, Gwan-young wondered how they could possibly do things he hadn’t done since before debuting.
But Tae-hoon still wasn’t finished. A small voice audible only to an Esper continued.
“Tomorrow I’ll probably be okay. Definitely.”
“……”
“So…”
Ji Gwan-young lifted his head with slightly widened eyes.
Only then did he finally understand the real intention his Guide was trying to convey.
The face completely stripped of caution surprisingly looked almost innocent, which instead made Tae-hoon a little startled.
For the first time, he saw hesitation on the face looking up at him. And Tae-hoon was grateful for it. And sorry.
Even though Gwan-young could’ve treated the rebound after sex as something Tae-hoon himself needed to endure and overcome, Ji Gwan-young had instead chosen to restrain himself.
This was someone who never obeyed anyone’s commands, someone no one would even dare criticize no matter how selfishly he acted. Yet toward Tae-hoon alone, he behaved with such devotion.
Smiling softly with curved eyes, Tae-hoon asked playfully,
“Could it be… you don’t like doing it with me anymore?”
In the end, a faint laugh-like smile escaped Gwan-young too. Because there was no way that could ever be true.
Taking off their clothes was far easier than Tae-hoon had imagined.
It felt so completely different from the first time—when preparing for sex had felt like being dragged to slaughter—that it made his chest ticklish somehow.
He’d even actively helped Ji Gwan-young remove his thin knit sweater.
This wasn’t merely progress anymore. It was practically becoming another person.
Of course, Tae-hoon’s awkward attempt at being proactive was simply meant to ease the burden his Esper carried. And there was no way Ji Gwan-young wouldn’t notice that.
Watching his Guide, who clearly couldn’t hide his nervousness yet still tried to act calm while offering his body, Gwan-young clicked his tongue inwardly.
That was why, when he led him to the bed and laid him down, he moved slowly, as though handling a doll that might break easily.
Even while kissing him, he’d listened carefully to Tae-hoon’s increasingly rapid heartbeat.
There was no need to explain further. But something else entirely ended up robbing Ji Gwan-young of words despite how carefully he’d been acting.
“…What?”
“Hah… wh-what?”
During the two times they’d had sex before, Choi Tae-hoon had never even dared move first.
The Guide had been so awkward about even spreading his legs that Gwan-young had always entered him from behind instead.
And yet now, that naive Guide, Choi Tae-hoon, sat there with a flushed face squeezing out lubricant and moving his hand behind himself with practiced familiarity.
For a moment, the Esper could only blink at the absurd scene before him.
One month and several weeks.
Even if they hadn’t had sex during that time, he’d still met Tae-hoon whenever possible and spent time with him.
Not only that.
Ji Gwan-young constantly observed his Guide closely enough to notice weight fluctuations, the difference in complexion between nights he slept well and nights he didn’t, even the cleaner voice and improved lung capacity from quitting smoking recently.
And yet this was behavior impossible without experience.
The sight of him biting his lip while twisting his body and slowly opening himself with wet sounds was so obscenely erotic that it was hard to believe it belonged within the behavioral range of “that Choi Tae-hoon.”
Ji Gwan-young couldn’t even imagine what could’ve happened over the past month for a man who once struggled just to say the word sex aloud to suddenly prepare himself alone to take another man inside him.
“Choi Tae-hoon, what the hell is that—”
“Ah, ahh! Center training! It was Center training!”
Realizing what his Esper’s expression meant, Tae-hoon’s voice rose loudly. But that only made Gwan-young even more dumbfounded. And slightly angry.
What kind of lunatics had designed what sort of insane training program to make a straight man prepare himself alone like this?
He honestly felt like ripping out the giant triangular sculpture standing in the middle of The Center and throwing it at someone while demanding answers.
Fortunately—or unfortunately—Tae-hoon quickly noticed the meaning behind his expression.
“They teach us with videos! Alone in the booth!”
“That’s insane. Choi Tae-hoon, don’t attend Center training anymore.”
“Some of it’s actually useful! Especially the parts explaining Esper research findings—they’re interesting.”
For the first time in his life, Ji Gwan-young found himself having this kind of conversation in bed.
Watching his flushed-red Guide desperately trying to defend The Center somehow, he let out a small sigh.
He forgot surprisingly often that Choi Tae-hoon was this kind of person with this kind of personality.
Truthfully, if you looked closely, Ji Gwan-young and Choi Tae-hoon were so completely different in every possible way that it was hard to understand why they even shared a Name at all.
Rather than blaming his partner for learning strange things over the past month, Gwan-young’s own fault for deliberately keeping his distance from Tae-hoon had been greater.
Still, part of him couldn’t help laughing in disbelief.
He’d always thought Tae-hoon was rigidly upright and inflexible, but he never imagined the man would prepare himself alone simply because “that’s what he learned in training.”
Staring fixedly at his Guide, Ji Gwan-young gently lifted and laid down the broad-bodied man—who lacked for nothing in either height or physique—as though handling a stuffed doll.
“Wah— why?!”
“How much more mannerless are you planning to make me?”
“Huh?”
mc is such a cutie
