SLC 53

“…Haah….”

“Haah….Haah.”

Their lips finally parted after they spent over ten minutes kissing while standing at the entrance.

“…You should wash up….”

Mok Seongha spread Kim Jinkyung’s legs and rubbed his member between them.

“Hmm.”

“…..If I transform while washing.”

“If we wash while kissing, maybe…”

“What if I transform then, hmm?”

Mok Seongha muttered as he nibbled and sucked on the back of Kim Jinkyung’s neck.

“Will you still let me do it even if I transform?”

Kim Jinkyung shook his head in response to Mok Seongha’s question.

“Then, let’s just keep going like this.”

Mok Seongha said as he slid his hand under Jinkyung’s t-shirt. His turgid flesh had been rubbing against Kim Jinkyung’s groin for a while now. Mok Seongha peppered kisses around his neck and stroked down his back.

“Ah….”

Shivers ran down Kim Jinkyung’s spine. The man repeatedly felt and touched Kim Jinkyung’s back, like a blind person trying to confirm a shape. Kim Jinkyung flinched in surprise at the sensation of the hand, which had been moving along his spine, suddenly digging between his buttocks.

“Why?”

Mok Seongha asked.

“It’s nothing.”

…I must have imagined.

Kim Jinkyung closed his eyes as he kissed Mok Seongha again. The hand that was kneading his buttocks rubbed that same spot again.

“Wait.”

Kim Jinkyung turned pale and grabbed Mok Seongha’s hand.

“Why do you keep touching there….”

“I know about it too.”

“H-how?”

“Since you didn’t teach me, Teacher, I studied on my own.”

Mok Seongha spoke and turned Kim Jinkyung’s body to face the wall. Then, he pulled down his pants and underwear. While Kim Jinkyung froze, startled by the sudden action, Mok Seongha knelt down.

“Can I practice what I prepared?”

“What? What do…!”

Kim Jinkyung couldn’t finish his sentence. His mind froze at an act he had never even imagined, and he couldn’t react. Kim Jinkyung abruptly turned around as though he was burned and clutched Mok Seongha’s hair when he felt a rough tongue between his buttocks.

“I-I don’t want to!”

Kim Jinkyung urgently shouted.

“You don’t want to?”

“Yes. Something like this….”

Mok Seongha stood up. Then, he scooped Kim Jinkyung up and threw him onto the bed. Only then did Kim Jinkyung see the man’s cock, which was erect enough to touch his belly.

Before, their acts consisted only of rubbing. He had been surprised by the size, but it had never felt threatening like it did now. Mok Seongha knew now. He knew exactly where to put that thing, and it wasn’t the belly button.

“Seongha-ssi. Let’s just talk….”

“Talk?”

Mok Seongha asked as he stripped off Kim Jinkyung’s remaining clothes and threw them below the bed.

“Doing this…. It’s too sudden…”

“Then I just have to say it first, right?”

Mok Seongha leaned his upper body over Kim Jinkyung and continued.

“I want to have intercourse with you, Teacher. Not just rubbing, but sex where I penetrate you and ejaculate inside you.”

Every word Mok Seongha spoke used precise terminology to describe the act. There wasn’t a single vulgar expression. Nevertheless, blood rushed to Kim Jinkyung’s ears, and they felt hot as if on fire.

“The end.”

Mok Seongha finished explaining and grabbed Kim Jinkyung’s ankles to spread his legs. As he looked down at the exposed area, Mok Seongha licked his lips like a beast with prey before him.

I’m going to be devoured.

Before he could react properly to the fear that invaded his mind, Mok Seongha moved first.

Kim Jinkyung had realized early on that he liked men. The object of his unrequited love was a man, and he always thought that if he ever dated someone, it would be a man.

But he swore that never once, not even once, had he ever imagined a man’s tongue touching him down there.

“A-ah, no. There…..”

A thick tongue began to lick his opening.

A beast licking a person had many meanings. Usually, it was an expression of social bonding, submission, or a peaceful intention not to attack.

But Mok Seongha was different.

The man’s tongue licked his opening and pushed the hole apart. Mok Seongha’s purpose was simple.

Sex.

“Ah, ngh…. Wait, please…ugh.”

Kim Jinkyung reached out and tried to push his shoulders down to stop him, but Mok Seongha only moved his tongue more fiercely. A chilly sensation washed over him whenever the rough surface of his tongue touched him.

“Seongha-ssi…, please….”

He felt dizzy and he couldn’t breathe well. The thick, powerful tongue pushed his hole apart and entered.

“Hng….”

The sensation of the tongue violating him like a snake made his vision flash.

The wet sound of flesh being pulled and sucked echoed. Kim Jinkyung’s toes trembled. He couldn’t speak because the shock was too great. A mix of shame and pleasure tightened its grip on his throat.

He could only think about escaping. His feet struggled and pushed against the sheets. A pair of large hands held Kim Jinkyung’s waist. Then, he thrust his tongue inside all at once.

“……!”

The tongue licked his inner mucous membrane. A gnawing pleasure rushed in like a wave. Only after a long time did Kim Jinkyung realize that he had ejaculated.

“Hng!…ugh.”

Kim Jinkyung burst into tears as he saw the sheets messy with his semen and his legs wet with the man’s saliva.

“….Why….”

The man, who was smiling like carnivore that just finished a satisfying meal after confirming Kim Jinkyung’s climax, froze in surprise.

“What’s wrong? Did I…did I do something wrong?”

Mok Seongha asked as he held Kim Jinkyung’s shoulders. The latter buried his face in the pillow and cried.

“Is this, is this not how you do it?”

Mok Seongha asked as he rubbed Kim Jinkyung’s ankle.

He never had the desire or intention to watch videos of other people getting it on, but he had endured his disgust and studied for Kim Jinkyung’s sake. Now that Kim Jinkyung had burst into tears, Mok Seongha was bewildered.

“Then how should I do it?”

Mok Seongha asked as he lay prostrate over Kim Jinkyung’s body.

“…Don’t do it.”

“Just put it in without sucking?”

Kim Jinkyung hurriedly looked up and shook his head. Tears pooled in his red, swollen eyes and rolled down his cheeks. Mok Seongha stared down at Jinkyung’s crying face.

“Don’t, put it in. That kind of thing….”

“Why?”

Seongha did not understand.

Kim Jinkyung had made a garden for him. Jinkyung said that the act of tending flowers for someone must come from a heart that treasures them. He also answered that he cherished Seongha very much and kissed him. Seongha could not understand what he had missed here.

“Why can’t I do it?”

Jinkyung wiped away his tears with the back of his hand.

“…I have something to ask you.”

“What is it?”

“Seongha-ssi, what do you think of me?”

Jinkyung asked as calmly as he could. This question had been circling his mind constantly. He knew Mok Seongha considered him special and followed him, but he needed to pinpoint that exact emotion.

“I want to have sex with you.”

Seongha continued as he looked down into Jinkyung’s teary eyes.

“I want to be by your side. I want to touch you.”

“…Not what Seongha-ssi wants to do, I mean, your thoughts about me….”

“You are like a fool.”

“…….”

“You are as stupid as you are foolish, and you have so many fears. I don’t even know why you cry. You are promiscuous, lewd from head to toe, and fuck, you are desperately obsessed with men….”

The description sounded more like an insult as it went on. Jinkyung looked up at Mok Seongha because he was so flabbergasted.

“But I keep thinking only of you.”

Mok Seongha rubbed Jinkyung’s eyes with his thumb to wipe his tears. Then he kissed the mole that was barely visible, hidden by the eyelashes.

“At first, I thought of your voice when you explained the problems.”

On nights when his mind was restless because of his grandfather, the teacher’s calm voice explaining math problems lingered in Seongha’s ears. It felt absurd at first, but later, he leaned on that sound to get through sleepless nights.

“After that, it was your hands.”

Seongha took Jinkyung’s hand and kissed it as he continued.

“After I rubbed my cock against your hand, I could see nothing but this. The color and shape of your fingernails appeared in my dreams….”

Once, Jinkyung’s hands appeared in a dream. In the dream, Jinkyung sat at a desk and solved problems while Seongha watched his hand. He did nothing else, yet when he woke from the dream, his groin was soaked. It was the nocturnal emission he had read about in books.

“The scent of your body, the color of your genitals, your vertebrae, things like that.”

Seongha listed points an ordinary human would not count and explained his feelings for Jinkyung.

“I like the things you teach me.”

Seongha leaned down and kissed Jinkyung’s forehead and the area near his eyebrows.

“I like how the things you gave me fill me up. …So, eventually…”

Golden eyes stared at Jinkyung. His pupils were like a deep ocean trench, he would lose his breath just by looking into them. The overwhelming pressure took the breath out of his lungs.

“I want my whole world to be you.”

A person might hear a confession from someone in their life. However, Jinkyung would likely never hear a confession more desperate than this for the rest of his life.

The cat in the box, which he had carefully opened, stared at him. The cat was alive.

“I, to you….”

Jinkyung hugged him and kissed him before Seongha could finish his confession. The latter seemed a bit surprised and hesitated for a moment, then he opened his mouth and responded to the kiss with more intensity than before

Hushed breaths leaked out between the soft, wet sounds. Seongha rubbed his lower body against Jinkyung while he held him. He pressed the tip of his penis against the hole that was slick with saliva.

“Ah..!”

Jinkyung trembled as he held Seongha’s arm. His expression stiffened suddenly when he saw Jinkyung’s reaction; he was shivering with fear at an act that could hardly be called penetration.

“…Are you scared?”

“Ah, …yes. A little…..”

Even as he spoke, Seongha pushed his hips up and penetrated deeper. Jinkyung bit his lower lip to stifle a moan. His eyes welled up with physiological tears as he felt himself stretch open.

“…I’ll do it.”

“…Yes?”

“If you want, I’ll even gouge out my eyes. I’ll pull out my teeth too, …so don’t be afraid of me.”

The man with the most beautiful eyes in the world expressed his affection in an almost brutal manner.

Kim Jinkyung shook his head.

“It is not that…. I….”

Jinkyung took a deep breath.

“…It is my first time.”

“What is?”

“Doing… this….”

Mok Seongha looked at Jinkyung with a face that said he could not understand.

Jinkyung never imagined a more humiliating time than when he shouted that he loved men would ever come.

“I mean, ..sex…”

His small voice echoed inside his throat. Seongha asked, “What?” He could not have missed it. He was someone who could hear the heartbeat of another person through a wall if he wanted to.

“…sex…”

His trembling lips could hardly form and spit out the word. Seongha looked at Jinkyung and asked, “What are you saying?”

“…I have never done it.”

Jinkyung confessed right then and there. He should have done this from the start. This was better than being treated like a messy person.

Seongha finally seemed to process the information and repeated to himself “it was his first time” with a smile on his lips.

It was a relief. At least he was not upset that I hid it….

“……!”

Jinkyung gasped a moment when the sudden pressure forced his breath out of his lungs.

“…Seong….”

Before he could even call his name, the man thrust his hips up once more.

“Ugh…!”

Jinkyung’s thighs trembled. Receiving a man’s genitals into his body was more fierce than he had imagined. Jinkyung could hardly breathe the moment the rough, hard penis entered and stretched his lower half. Every time he tried to open his mouth to breathe, the man slammed into him even harder and blocked his windpipe.

“You don’t have to do that.”

Seongha spoke as he bit his lower lip.

“You don’t have to pretend it is your first time, because that is fine… fuck.”

As Seongha thrust his waist, his tight glute muscles rose to display their lines.

“No, really…. Hng….”

Seongha hugged Jinkyung and thrust his cock to the root. The hole, stretched to its limit, accepted the large dick as it twitched.

“First time, my foot.”

A light flashed in his golden eyes. It was as if small golden sparks were flying. As he continued, he clenched his teeth, repressing his growing urge.

“To be this good at sex. You drive me crazy….”

“…Seongha-ssi…hng”

Seongha buried his face into Jinkyung’s neck. He bit and sucked his flesh like a starving beast. In the midst of this, he hurriedly thrust upward.

“Ah, ..ugh, ah….”

The hole, stretched to its limit, repeatedly took in and let out the member, and a sticky, wet sound rang out from below. Jinkyung felt like he would lose his mind. The sensation of the rough cock rubbing against his inner walls ran from his lower body to the top of his skull. His vision flickered and his eyes stung. The sensations flooded in like a tidal wave, crushing his entire body.

“Ah, hng…, ugh.”

“…Fuck.”

Seongha pulled out his fully hard cock and thrust it back in. The inner walls wrapped around his penis and refused to let go.

In reality, it was a lie. He wasn’t fine. The mere thought that another bastard might have seen this version of Jinkyung made him feel like he had swallowed a red-hot fireball. The emotions that remained after burning through his esophagus, stomach, and intestines dominated his whole body.

“Hn…ng. Ah…. Ah!”

Ragged breaths leaked out from between Jinkyung’s well-shaped lips. Tears welled up in his eyes, which were red with heat. Blood rushed to his fingernails that gripped the man, and they showed a particularly red color.

Every sensation Jinkyung gave him stimulated him so vividly that it was painful. His stomach churned and his vision shook.

“If you ever….”

Sharp, lengthened claws ripped through the blankets, and grown fangs shone in the darkness.

“……!”

Jinkyung doubted his eyes when he saw the black ears revealed on the man’s head and the tail. He had seen him transform into a panther before, but this was the first time panther-like physical traits appeared while he maintained his human form.

“If you ever do this with another bastard besides me.”

Jinkyung groaned and furrowed his brows as he felt Seongha’s cock thrusting in. It felt as if the surface of the penis had become rougher than before, though it might have been his imagination.

“I will turn into a beast and have sex with you right in front of that bastard.”

“…What….”

“I will have sex, just to show him, ..someone like you….”

A low growl mingled with the man’s breath. It happened in that very time. Mok Seongha’s penis grew larger, making him feel fuller as his hole closed around it. Jinkyung grasped Seongha’s arm.

“Seongha-ssi, wait, this, it is strange…. Ah!”

Seongha hurriedly sucked Jinkyung’s lips. The teeth of a sharp predator bit into the soft inner membranes of his mouth and his tongue. He wrapped his long tail wrapped around Jinkyung’s thigh.

The member that had dug into his inner walls swelled as if it had a will of its own. Jinkyung burst into tears and grabbed Seongha’s shoulder as he felt like their lower bodies had become locked together.

“Ugh…nng, ah, ha….. Seongha-ssi, it is strange, please…”

All the words he muttered as he pleaded were swallowed into the beast’s mouth. The glans scraped and poked the prominent ridge inside. Jinkyung was shaken by an intense mix of pleasure and anxiety. It was the same with Mok Seongha.

“Hn…ng. …Fuck.”

He also could not keep his senses due to the pleasure he experienced for the first time. His entire body was enveloped in a wave of bliss. His vision flickered, as if he were about to pass out.

“Ugh, ahh…!”

Jinkyung was the one who ejaculated first. When his hole, which was so tight he thought it could not tighten further, repeatedly contracted around the cock, Seongha gritted his teeth. His jawline stood out as he clenched his molars. Sparks flew in his golden eyes. He ejaculated lukewarm semen into the hole. It did not end with just one time. The man moved his waist a few more times. Each time, he shot a massive amount of semen into Jinkyung’s hole.

“Haah…. …Haah.”

Seongha breathed heavily for a long time even after he finished. He looked like a beast catching its breath after a hunt. Then he noticed Jinkyung, who was sobbing.

“Why are you crying?”

Mok Seongha asked. Kim Jinkyung looked up at him with eyes full of tears and answered.

“Please… take it out.”

Mok Seongha blinked as he realized what Jinkyung wanted him to pull out.

“I can’t pull it out.”

“What?”

“It won’t come out.”

Jinkyung looked down. He did feel the sensation of their lower bodies locking together during sex. This was his first time for everything, but since it was a sensation he had never even heard of, his mind was full of questions about whether this was normal. Of course, all thoughts had vanished from his head during the frantic thrusting that followed.

“Why? Why will it not come out?”

The absurdity of the situation caused his flowing tears to instantly stop.

“I told you before. If we have sex, there is a one hundred percent chance of pregnancy.”

The words he heard previously came back to him. At that time, he thought it was just a matter of probability; he never even considered a physical function like this.

“That only happens to… canines. Seongha-ssi, you are a cat.”

Jinkyung barely managed to speak as he searched his biological knowledge from science magazines. It was a short essay about the evolutionary differences between the mating of solitary cats and pack-dwelling dogs.

“It doesn’t make sense.”

Jinkyung did not know exactly what system the genes Mok Seongha possessed had evolved through, but the current situation did not fit his common sense.

“Does it make sense for a human to turn into a panther in the first place? Why do you only care about realism when it comes to my dick?”

“…….”

Jinkyung had nothing to say. The person in front of him was the very embodiment of a denial of modern life science. Even so, wasn’t this a bit too much?

While confused thoughts flashed through his head, Jinkyung noticed the black, round ears on the man’s head.

“What on earth is that again….”

Mok Seongha moved his ears and asked, “Ah, this?”

“Why did those come out?”

“I don’t know why this is happening either.”

The rounded ears flicked here and there. Then, Mok Seongha’s expression stiffened as if he had thought of something.

“Can I not have these?”

“Ah….”

Jinkyung said they should only engage in sexual acts in human form, but he was also confused. He did not know where to draw the line.

The man’s expression remained the same, but his ears drooped slightly. Jinkyung sighed.

“Then just the ears and the tail. Nothing more than that. Other things…. Ugh!”

Mok Seongha hugged Jinkyung. Because of that move, the cock that had not yet come out poked his inner walls.

“Teacher.”

Jinkyung could not help but notice the heat in the voice that called him.

…He is cute. Isn’t it a foul for a handsome man to even have cat ears?

Jinkyung answered with a “Yes” as naturally as possible. Mok Seongha pulled Jinkyung’s hands to wrap around his own waist, then he tensed his thighs to deepen the connection.

“……!”

Their locked lower bodies rubbed together with a squelching sound.

“Ah, ugh….”

“You won’t get pregnant, right?”

“…Ugh… what?”

“This, it probably will not come out all day.”

Mok Seongha murmured as he looked down at Jinkyung’s lower abdomen. Jinkyung’s mind went blank even though he knew that such a thing naturally could not happen between men.

Common sense did not apply because the other person was a being who destroyed all logic of life science.

...What if it actually happens? For some reason, I feel like it might be possible for him…. No. I am a normal human, so there is absolutely no possibility, …but even so, just in case….

“You won’t get pregnant. Right?”

Mok Seongha asked again to confirm and thrust his cock in. Jinkyung shivered at the sudden wave of fear.

“Hng, Seongha-ssi, take it out first, ah…!”

“I understand. I will take it out now.”

He took the words “take it out” to mean something entirely different and moved his hips like a madman. Jinkyung’s penis, stuck under the man’s rock-like body, twitched and began to harden. Mok Seongha’s eyes sparkled as he noticed Jinkyung’s arousal.

He grabbed Jinkyung’s penis with his large hand. Then, every time he thrust his waist, he moved his hand up and down to provide stimulation from both the front and back.

“Ugh, hng…ng. Ah, ah! Seongha-ssi, your hand…. Ah, slow… ah!”

Jinkyung ejaculated once more in Seongha’s hand, and Seongha likewise ejaculated inside Jinkyung shortly after. The tip of his cock, swollen as large as an adult man’s fist, did not subside even after ejaculation.

“Please… take it out.”

“I told you I can’t take it out. …Ah, Teacher….”

Seongha’s body moved again. After that time, his memories were disconnected.

Jinkyung cried many times, begged him to stop, and clung to him before he finally lost consciousness. Whenever he opened his eyes, his body shook from the man’s movements and the repeated ejaculations.

“Please, …I can’t. My lower half… it is too swollen….”

His inner walls were swollen with heat because the rough surface of Seongha’s cock thad penetrated him dozens, even hundreds of times.

“I will treat you later.”

Seongha whispered as he kissed Jinkyung’s cheeks, nose, and eyes in turn.

“I will lick it for you….”

Seongha put Jinkyung’s hand in his mouth and sucked on it. At the same time, his tail rubbed against Jinkyung’s other hand. Jinkyung’s heart weakened at the behavior, which appeared to be that of a spoiled little beast, and he eventually nodded.

Seongha exhaled and spread Jinkyung’s legs. He then repeated the thrusting at a speed incomparable to before.

“Ah, ugh, please.., ugh,..hng.”

“Teacher.”

Seongha kissed the shaking Jinkyung all over and repeatedly called him.

“…Yes.”

He tightened the arms that held Jinkyung as soon as he barely answered. Then he muttered a promise.

“I will do well.”

“…….”

“I will keep doing better and better….”

Jinkyung wanted to say that he could not possibly do more or better than this, but his mind went white. He clutched the sheets and barely managed to breathe as the sensation of being shaken up and down took over.

Seongha called Jinkyung’s name and put his full weight on him. The frantic penetration continued, and Jinkyung cried. Amidst all this, he felt glad the long-term students next door and across the hall had moved out.

“Teacher….”

The last thing he remembered was the image of him being overtaken by the large beast.
