Instead of answering, Ji Gwanyeong chose to set the guide down in front of the mirror. Taehun, unable to support his body, which had been suddenly lifted, swayed and almost collapsed, but thanks to the Esper’s skillful support, he managed to stand, leaning against him. His legs, weak and unsteady, stumbled a few times, causing the gel that was still lingering in his private parts and his own cum to run down his thighs.

The Esper whispered in his guide’s ear, a bit sternly.

“Look straight ahead. Choi Taehun. That way, if you end up meeting some other damn partner, you’ll know how to do it right.”

Choi Taehun closed his eyes, unable to bear the sight of his member, his crotch slick with cum and gel, clearly visible in the narrow space of the mirror. But it didn’t last long. The Esper’s hand moved repeatedly over his member, which was soaked and limp from receiving the man.

“You’re quite conservative, so you’ll probably prefer missionary. Imagine pushing yourself into your partner’s wet spot. Tightly gripping, in that slippery place… slowly.”

“Ugh! Ji, Gwanyeong, ssi, wait, just, stop, hic, hic, ugh…”

The hole, still aroused, twitched and made a lewd, sniffling sound just from the tip of his finger tracing its entrance.

The lewd words he deliberately chose, along with the sounds coming from behind, brought a mix of excitement and shame. The sensation of his fingers being gripped by the wet spot, slowly entering as the Esper said, was vividly real, almost excessive. Choi Taehun’s toes curled tightly, his hips swaying with the tantalizing stimulation.

His well-defined back bore faint marks from their previous encounter, and sweat dripped down the muscles engraved with the Esper’s name. Ji Gwanyeong’s head buzzed, his lower abdomen ached unbearably, as he felt the warm inner walls tightly gripping his fingers.

“Then I’ll watch you, and when you move your hips, I’ll grab your rear and spread it open. You’ll need a lot of gel. Choi Taehun, you’re quite thin.”

“Gwanyeong, ssi, please, ugh, nghh…”

The Esper smiled languidly. But his crescent-shaped eyes were strangely subdued with excitement. Ji Gwanyeong sat Choi Taehun on his lap and held his legs open, preventing him from closing them.

The blatant posture would make even a low-class prostitute blush, and Taehun’s eyes turned red. When the Esper’s member plunged all the way in, his rough pubic hair touching his entrance, the stimulation was so intense that he could only let out a gasping breath instead of a moan.

His reflection in the mirror was truly obscene, enough to make his eyes blur.

He had never imagined himself swallowing a man’s member, his hole stretched to its limit. Choi Taehun, despite the direct stimulation of the Esper’s glans pressing against his prostate, was captivated by the lewd sound of the rubbing and the sight it presented, taking a deep breath and slowly regaining his balance.

“From now on, how does it feel to get pounded by your damn partner while I’m shoving it in your rear? Do you want to do this?”

“No, I don’t want to, ugh, hic…!, ugh, ugh, ah!”

Taehun’s hips bucked. The guide gasped for breath, his body reaching its limit, trying to escape the Esper. But Ji Gwanyeong wasn’t a predator who would let his prey escape.

“You seem to be having a pretty nice dream, but stop it, Choi Taehun.”

The force with which he pulled the man’s limp body towards him was strong. The sight of him, lying face down, his hole still open, wriggling his hips, was a lewd stimulant. The Esper tilted his head languidly, greedily grasped his trembling pelvis, and thrust his enraged member deep inside, all the way to the root.

The piston-like motion, which wouldn’t give him a moment to catch his breath, began, and Taehun’s voice erupted in a raspy moan. The stimulation, which pressed against his prostate and dug deep inside, was too intense to be described by the word “pleasure.” The sound of the fleshy parts, slick with gel and something else, colliding was loud and messy.

His moan, which sounded almost like a cry, made Ji Gwanyeong lean down and kiss Taehun’s ear, whispering softly.

“Ah, ah, ah, ugh, yes, please, please, ah!”

“I have a bad temper, as you know. I’d probably kill you both rather than watch that. And then, before long, I’d die too.”

Ji Gwanyeong didn’t bother to hide the roughness in his own voice as he watched Choi Taehun, oblivious to the sounds he was making and the face he was making as he begged. The more intense the act became, the hotter the breath and the lower the sounds that escaped the Esper’s lips.

“I’d rather have a happy ending where people survive than film a pathetic, third-rate melodrama where all three of us die. Ugh, let’s go with a story that sells well. …Right? Taehun?”

“Ugh, ah, ah, ah…”

Choi Taehun reached his peak, letting out a sharp cry as he went limp in Ji Gwanyeong’s grasp. The Esper bit his guide’s nape, teeth bared, and released his load into the inner walls, which were tightly contracted with excitement.

Taehun, oblivious to the man’s cum pouring into his rear, which had long been slick with gel, writhed uncontrollably, unable to move. Ji Gwanyeong’s mouth went dry as he watched Taehun’s body tremble, followed by the lewd tightening.

The sensitive insides were overwhelmed, reacting to the slightest movement of Ji Gwanyeong’s member. He didn’t pull out immediately after coming, but pressed deeper, slowly rotating his hips, causing the guide to let out a faint sob, almost a whimper, from the intense pleasure, which was too much to be called an afterglow. This was the first time he had been stimulated so relentlessly.

Ji Gwanyeong clicked his tongue at Choi Taehun, then gently kissed his forehead, as if to soothe him. The guide, as if something inside him had finally broken, couldn’t hold back the sniffles he had been suppressing, and he gasped for breath, crying softly.

Only then did the Esper think, maybe I went a bit too far. The guide, his breath ragged, managed to string together a few broken sentences.

“Get away from me. Seriously, you’re… the worst.”

“No. I’m not leaving. I’ll clean you up.”

But Choi Taehun was unlucky, because Ji Gwanyeong was Ji Gwanyeong.

The guide, finally realizing that the man was gently holding him, hit him as hard as he could with his weak hand, expressing his displeasure. The Esper chuckled, a slight frown on his face, at the ticklish punches.

***

Choi Taehun was angry. And when Choi Taehun was angry, Ji Gwanyeong was equally furious. In other words, the two of them were in a silent, tense standoff. The cause of the discord was simple. The guide was still irked by the Esper’s behavior from yesterday. It all began with Taehun being unusually sulky, which, for him, was rare. Then, Ji Gwanyeong, with that impeccable, stoic expression of his, had casually remarked, “You’re the one who messed up, Choi Taehun.”

That was the breaking point.

Choi Taehun snapped at those words, his temper flaring as he shouted, “What did you say?! Ji Gwanyeong, you really—!” He stormed out of the apartment, slamming the door and stomping loudly. In response, Ji Gwanyeong was infuriated by his guide’s reaction.

The result of this confrontation was an oppressive silence that hung over the Center’s First Research Lab, so thick that even breathing seemed muffled.

“…”

“…”

The stillness was finally broken by Lee Miyeon’s voice. “Hmm, hmm. The minimum matching score is 90.1, and the maximum is 167.3… The low score has definitely improved since last time. See, Taehun ssi? I told you it wasn’t a big deal. It really just depends on your condition.”

“Yes. Thank you.”

Lee Miyeon’s smile was warm, her eyes crinkling with amusement at Taehun’s polite reply. Yet, despite her pleasant demeanor, her mind was racing, trying to understand why this seemingly perfect match had such a remarkable score, while clearly being at odds in the moment. Something was definitely off between them.

She watched curiously as Ji Gwanyeong, with his icy demeanor, insisted on sitting right next to the guide during the matching test. It puzzled her. Why, if they were at odds, did they insist on sitting next to each other?

Ji Gwanyeong, usually attentive to every movement of Taehun, sat there with his sharp gaze fixed intently on the table, his head slightly turned. Meanwhile, Taehun was sitting with his body turned away from the Esper, legs crossed in a clear sign of discomfort.

Lee Miyeon inwardly questioned, If you’re going to act like this, why sit next to each other?

She handed them a thick questionnaire, deciding that today’s activities would need to be more straightforward given their current mood.

“This is a mandatory pair psychological survey. It may take a while, so please take your time.”

“Yes.”

Typically, Ji Gwanyeong would have made a sarcastic remark by now, but today, he remained silent. Taehun, seemingly ignoring the Esper entirely, took only his own questionnaire, leaving the other one in the middle of the table.

At that moment, Ji Gwanyeong’s eyebrow twitched slightly—an unmistakable sign of irritation. It was subtle, but to those who knew him, it was clear. The researchers, who had learned to read this cue, exchanged silent glances. Even Oh Yeon, standing a little farther away, sighed in frustration upon witnessing the Esper’s displeasure.

Ji Gwanyeong, not accustomed to being ignored, finally spoke. His voice, though calm, carried an edge.

“Why waste time on this trash… Choi Taehun, why don’t you step outside for a bit?”

True to form, the moody Esper made a sharp comment before any of the research protocols could take effect. His usually composed expression shifted into one of clear displeasure.

Choi Taehun, though cold-eyed, replied quietly, “Why?”

“Why do you think? Should we talk here?”

Despite his annoyance, Taehun wasn’t feeling well today. The marks from their last encounter—the faint bruises and soreness—were starting to hurt, the pain settling deep into his muscles. Ji Gwanyeong could tell. He always could. He knew from the strained sound of Taehun’s breath as he tried to sit up.

Finally, with a deep sigh, the guide pushed his chair back and stood up.

Taehun was one of the few in the Center who could stand up to the powerful Esper. As he left the room, the researchers gave him a polite nod of farewell.

The question hung in the air: Why were they fighting?

The research lab fell silent again, the tension palpable.
