Gwanyeong’s hand moved carefully along the name on his back. Taehun, realizing what the man was touching, closed his eyes tightly. With his vision blocked, all his senses focused on the fingertips tracing his back.

Truthfully, Ji Gwanyeong had always been skeptical about names.

He’d always looked at the phenomenon of someone’s name appearing on their body, without knowing who it belonged to, with a critical eye. So, when it happened to him, he scoffed and easily dismissed the name Choi Taehun from his mind. He was certain that the connection of names wouldn’t have any impact on his life.

But now, Ji Gwanyeong was somewhat regretting his arrogance. Actually, quite a lot. It was a rare occurrence for him.

He’d manifested as a guide at the age of five.

Ji Gwanyeong wondered what would have happened if he’d met Choi Taehun at twenty-one, when he’d awakened as an esper.

Fifteen-year-old Choi Taehun.

Choi Taehun, who had been a guide, existing solely for him, since long before he could even remember. If they’d met then, his name would have definitely manifested sooner. The esper, his name etched on his back, rippling with every movement of his back muscles, slowly ran his finger down the guide’s back, who was trembling, ready to receive him.

Due to his position, the hole was exposed in a way that was almost embarrassing. Every time Gwanyeong’s hand traced over it, the thick gel dripped onto the bed. Choi Taehun instinctively tightened his hole, never having been touched by anyone before, then flushed crimson as he realized how it might look to the man who was about to penetrate him. His arms, which were supporting his body, trembled, but holding on like this was his last shred of pride as a man.

Ji Gwanyeong squeezed more gel onto Choi Taehun’s back, soaking it thoroughly. Taehun, feeling his back become damp, as if leaking precum, shuddered and let out a small whine.

“Do you really have to use that much…!”

“It’ll hurt if it dries out. It needs to be well-lubricated.”

Oh my god. Choi Taehun shut his mouth again. Then, he quickly gasped as he felt a finger slowly entering him. After he’d come once, his body was warm and sufficiently lubricated, and he easily clamped down on Gwanyeong’s finger. Taehun hated it. The single finger moved in and out like a piston, then two fingers joined in. Ji Gwanyeong began to seriously widen Choi Taehun’s hole. The fingers poked in, then slid out, exploring the hot inner walls, making a squelching sound as the hole stretched open.

The guide tried his hardest not to make a sound, but this time, he couldn’t cover his mouth with his hand.

“…Ugh, ugh….”

The esper patiently loosened the tight hold, then discovered a spot where Taehun involuntarily swayed his hips when he pressed a certain point a few inches in. Taehun couldn’t even moan when he pressed that spot, only letting out sharp intakes of breath.

Ji Gwanyeong withdrew his fingers, still unable to grasp what he’d just felt, and pushed his member into the trembling guide’s hole, his vision momentarily flashing white. Startled by the sudden insertion of the hard, hot flesh, Choi Taehun instinctively clamped down on it.

“Ugh… Choi Taehun. Relax.”

The man’s voice, no longer the usual polite tone but a commanding one, sounded slightly hoarse. Choi Taehun, obeying the man’s command to relax, gasped for breath as he felt the sheer size of the member, a different experience entirely from fingers. The arms that were supporting his body were now trembling visibly.

Ji Gwanyeong, as if praising Taehun for his effort to relax, stroked his sweaty back, then plunged his member deep inside him. Taehun’s interior, slick with gel, greedily swallowed Gwanyeong’s member all the way to the root.

The esper began to thrust wildly. The sound of his lubricated body slamming against him was loud.

“Ugh, ah, aah, Ji, Gwanyeong, slow, ly…!”

Taehun was completely out of it. The member thrusting inside him was buried deep, making his vision go white every time it slammed against his depths. The strange sensation of his inner walls being pulled along as it withdrew made his hips sway uncontrollably, as if they were no longer under his control. All Choi Taehun could do was beg the man who was ravaging him, a plea he desperately didn’t want to make.

Please, please, slow down.

Ji Gwanyeong, catching his ragged breath, kissed the name etched on his back and thrust deeply. Taehun gasped sharply, a sharp “Haak” escaping his lips. He pressed his body against Taehun’s, fully inserted, and deliberately pressed against a certain spot, slowly, while biting his ear. The guide, who had been holding on with all his might, finally broke.

But the esper didn’t release him, he continued to thrust relentlessly, his body pressed against him.

“Hi, hiik, ugh, ah, ah-.”

“Does it hurt?”

“…Please, please, ah, ugh, aah…!”

Taehun let out a series of whimpers, no longer sure who he was begging or what he was begging for, trying to escape the thing inside him.

But he was too weak, and the monster was thirsty.

Ji Gwanyeong licked the corner of Taehun’s eye, which was streaming tears from the overwhelming stimulation. He had plenty of time.

* * *

Am I even alive?

Choi Taehun, lying in bed, reached for the ceiling. Or rather, he tried to. But he couldn’t move a single finger, let alone his arm. Even in this situation, waking up naked, skin on skin with a man, he couldn’t muster the energy to be surprised.

This is what it means to be completely drained, Taehun thought, unable to move.

“…You’re awake?”

A low voice reached him. Taehun managed to turn his head slightly. Ji Gwanyeong, looking more languid than usual, smiled and lightly brushed his lips against Taehun’s hair. Choi Taehun tried to speak, his mouth moving. But no sound came out, and after failing to speak several times, he made a sound that was almost like a growl.

“…Y-yes.”

“You’re quite hoarse.”

Choi Taehun furrowed his brow at Ji Gwanyeong’s words.
“Who’s fault is this right now!”

But it really was strange. He never expected to feel this exhausted, to the point of not having the strength to move a finger. The Esper from last night had been persistent, but not rough… Right, just as he asked, it hadn’t been painful. Taehun realized for the first time that moving slowly wasn’t comfortable at all. He learned that if you moved slowly and pressed in a certain spot just right, it could really make you lose your mind.

However, no matter how much he thought about it, he never expected that someone with his healthy constitution would find it so difficult to move after just one sexual experience with someone of the same sex. Taehun barely managed to convey his confusion to Gwanyeong, and Ji Gwanyeong tilted his head slightly before hesitating for a moment and then contacting the center. Of course, this was the worst way possible to approach the situation.

“Mr. Taehun had sex, and now he says his body has no strength, it feels weird… is this some kind of aftereffect from sex?”

…Shit.

As soon as Taehun’s strength returned, he seriously wanted to hit Gwanyeong. But despite this inner thought, the guide had to spend the whole day lying down, sick, accepting food from the Esper, and even receiving the embarrassing help of being carried to the bathroom and back to bed. It wasn’t until the late afternoon the next day that he was able to lean on Gwanyeong and barely make it to the center. It went without saying.

Once they entered the center, the guide kept his gaze fixed on the ground, unable to meet the eyes of the familiar faces. However, the researchers looked quite serious. Taehun nervously swallowed dryly. Oh Yeon spoke in a soothing voice to Taehun, as though trying to comfort him.

“It’s a rebound.”

“…Huh?”

“It’s a kind of reaction to the mental rejection that comes with a high match rate. Think of it as a rebound effect.”

That’s right.

Even though they had paired Taehun, the guide, with the highly-strung Esper, fearing he might cause an incident, it was rare for the physical aspect to be mixed right away. Normally, mental connection was established first, followed by physical contact. This was to avoid dealing with a rebound effect. Taehun, hearing that, thought to himself, ‘I guess it’s true that you shouldn’t jump into sex first.‘

However, the researchers, with their serious faces, exchanged glances among themselves, seemingly entertained by the realization that the cheerful assumption they had made had actually come true.

The most amused was, of course, Imihyeon.

“…But, it seems like Ji Gwanyeong is fine.”

Gwanyeong, who had been silently sitting beside Taehun, raised his eyebrows slightly. What did that mean? It was somewhat funny, and Taehun couldn’t help but feel a little sorry for her. Miyeon squinted her eyes as she continued.

“Taehun was practically immobilized by his rejection, but Gwanyeong here doesn’t seem to have any rebound effects? Wow, who would have thought such a thing could happen? Oh my, this is… fascinating.”

After they shared their bodies, Guide Choi Taehun suffered from a terrible rebound. However, Esper Ji Gwanyeong didn’t experience any rebound at all. The meaning of this was crystal clear.

‘Esper opened his heart to the guide. But the guide…’

Taehun blinked his eyes wide as he finally understood the sentence. Of course, a small laugh escaped from Esper’s lips. Honestly, to be completely truthful, Gwanyeong was slightly annoyed. He even had the thought, for about 0.01 seconds, that he might want to choke the guide, who was next to him with a calm expression.

…Was it really that unpleasant for you, sleeping with me?
To the point where you can’t even move a finger from the aftereffects?

Gwanyeong, unlike Taehun, thought about how ‘completely fine’ he was and became even more upset. Tilting his head slightly, Gwanyeong remained silent for a moment before speaking in a low voice.

“…You gasped, begged even cried and moan under me when we were doing it, but now the result was you rejecting me?”

Pfft.

Taehun almost spit out the water he was drinking, not understanding what the Esper next to him was saying. What? What did you just say?

“Is it because your body and mind aren’t in sync?”

“…What, uh…!”

“Well, it’s kind of cute in its own way… but it doesn’t feel great.”

The researchers nodded knowingly.
As expected, this Esper had a bad personality. No doubt about it!
One would think there was no such Esper anywhere in the world who would speak like that to their guide, who was suffering from a rebound. However, Gwanyeong simply smiled lazily and rested his chin, staring at Taehun, who looked like he had been stunned.

“Looks like I’ll have to get you to say ‘let’s have sex’ first, Taehun.”

The guide’s face turned bright red at that. It was already embarrassing and mortifying that everyone at the center knew he had been in the arms of another man, but now… crying and begging? His body and mind not in sync?

Taehun yanked himself away from the man who had held him the previous night, shouting in a panic. His voice cracked slightly, his face flushing red, unable to hold in the shouts.

“I’m telling you, I will NEVER, EVER, NEVER be gay!”

“Feel free to say that all you want.”

“We’re doing this out of necessity! You’re the Esper, Ji Gwanyeong, and I’m the guide!”

“Mm-hmm.”

Gwanyeong flashed a charming smile. Taehun, still flushed, glared at the man who was smirking at him with an audacious grin. His back, engraved with his name, burned with heat.
