SLC 23

Mok Seongha clung to Kim Jinkyung and pleaded. His voice was similar to the one he used when he had asked Kim Jinkyung to play along in that clumsy act to persuade his grandfather. No, it was more desperate than that. It was a voice tangled with sincerity and desire.

“Help me, this….”

Mok Seongha rubbed his lower body against Kim Jinkyung’s thigh and begged. Jinkyung wanted to cry. It felt like tears would spill out the moment he relaxed even a little.

“…You can just do it yourself, right?”

“What….”

“That.”

“So… how?”

Kim Jinkyung felt frustrated. Did he really have to explain this step by step to a twenty two year old adult? Then a disturbing thought suddenly crossed his mind.

“…Don’t tell me you’ve never done it before?”

“What?”

His pronunciation was slightly slurred due to the fever.

“Mast…turbate.”

“Why do that..”

Mok Seongha buried his forehead in Kim Jinkyung’s shoulder and muttered grumpily. Kim Jinkyung recalled the book that Mok Seongha had confidently thrown at him.

“Puberty and Beautiful Sex”

When the robust man over twenty had said he had completed sex education with that one book, Kim Jinkyung could not understand it. It had been the same when Mok Seongha said he had never watched videos or been curious. But it made sense. Since he didn’t have sexual desire, he had no reason to be curious.

“How do you do that?”

Mok Seongha asked. In this situation where a man one head taller than him clung to him like a child and asked about the method of masturbation, Kim Jinkyung felt the world spin before his eyes.

“Did you not see it in the book?”

“It is not there.”

Kim Jinkyung would send a complaint email to the publisher. If he got out of here safely, he would definitely complain.

“…With your hand, hold it.”

Kim Jinkyung explained as calmly as possible in a trembling voice. Mok Seongha lowered his hand down as Kim Jinkyung had said. While grasping his swollen penis over the clothes, Mok Seongha asked “Like this?”

“No, put it inside the clothes directly….”

While speaking, Kim Jinkyung’s face gradually grew hotter. He had never imagined in his life that he would say such lewd words to another person.

Mok Seongha tried to unbuckle his pants, but fumbled repeatedly because of his weak hands.

“Fuck.”

He was sympathetic to the nervous curse. The man was unfamiliar and clumsy with this entire situation. He could not even move his hand properly due to the heat rising in his body. After watching him fumble several times, Kim Jinkyung bit his lips. In the end, he helped him pull down the pants. When the tautly swollen flesh popped out, Kim Jinkyung quickly turned his head away.

Mok Seongha grasped his own penis with his hand. He looked at Kim Jinkyung, urging the next step.

“Move your hand up and down….”

Mok Seongha tried to do as instructed, but since his weakened hand did not move properly, even that appeared difficult.

“…Fuck.”

The man bit his lips as though he was in pain. Blood trickled down between the lips pierced by the sharp teeth.

“You can’t do that.”

Surprised, Kim Jinkyung put his hand in his mouth. Mok Seongha bit Kim Jinkyung’s hand as it entered his mouth. It was animal instinct.

“Ugh.”

Kim Jinkyung grimaced at the intense pain that tore through his skin. Mok Seongha ceased biting shortly after regaining consciousness.

“I am sorry. …Now…”

While murmuring, Mok Seongha brought his mouth to the back of Kim Jinkyung’s hand again. The frightened Kim Jinkyung tried to pull his hand back but Mok Seongha was faster.

“…Stay still.”

Mok Seongha began licking Kim Jinkyung’s hand as he held it. When the hot and thick tongue was swept across the back of the hand numerous times, the wound vanished as if it had never been there.

Kim Jinkyung held his breath and watched the scene. Although he had experienced it once before, it was hard to believe even while seeing it.

Even after the wound disappeared, Mok Seongha continued licking his entire hand thoroughly.

The tongue moved between his fingers where the blood had trickled. The sensation was vivid. Kim Jinkyung quickly turned his head away. His heart started to race.

“Don’t talk about…this too.”

At Mok Seongha’s words, Kim Jinkyung nodded his head slightly. Secrets kept piling up. His chest became stuffy.

“…Teacher.”

“Yes?”

“What should I do next?”

“You can move your hand slowly.”

“…I can’t?”

“You are squeezing too hard….”

Kim Jinkyung closed his eyes and reached down with his hand to help loosen Mok Seongha’s fingers.

“Only to this extent….”

“And then?”

Mok Seongha asked persistently like a model student urging an answer.

“Move it….”

Mok Seongha began to move his waist. Then, since Kim Jinkyung could not untangle their intertwined fingers yet, the flesh rubbed against his hand too.

“Just a moment, my hand….”

Kim Jinkyung tried to pull his hand away, but it wasn’t easy because Mok Seongha was moving his waist.

“…Hey.”

Mok Seongha called out softly to Kim Jinkyung, who was struggling and trying to pull away. The heat that emanated from his low, cold tone warmed Jinkyung’s ears.

“Teach me properly.”

“I’ve already taught you everything. …You can do it on your own.”

“…I don’t know.”

Mok Seongha was a student who learned quickly. He absorbed whatever was taught rapidly and applied it well. He tended to ponder difficult problems to the end and try to solve them himself. So Kim Jinkyung evaluated Mok Seongha’s learning ability very highly. It was the first time such a student abruptly gave up saying he couldn’t do it like this.

“I said I can’t do it.”

“…….”

Blood flowed between his bitten lips, and his pupils still maintained a narrow and long shape. The man with an incomplete and precarious appearance looked at Kim Jinkyung.

“Teacher…. Help me.”

Hey, you bad bastard. Why are you calling me teacher at times like this?

“Please.”

Unable to overcome the desire whose solution he did not know, Mok Seongha wriggled his body here and there. Each time, the firm and heavy flesh rubbed between Kim Jinkyung’s fingers. It resembled the pitiful movements of a beast facing its first heat.

“Teacher….”

The golden eyes were glued on Kim Jinkyung. The latter bit his bottom lip and collected his thoughts. Slowly, he moved his hand. A muffled groan escaped Mok Seongha’s throat.

“Uh….”

The handsome man’s face was clouded and distorted with desire. Kim Jinkyung turned his head.

I can’t see anything, I can’t hear anything! It’s just my hand.

Reciting the same words to himself, Kim Jinkyung moved his hand up and down. A hesitant breath escaped his lips.

“Haa…”

Heat seeped through the rough, languid voice. His ears felt hot. He wished he could block them.

Kim Jinkyung closed his eyes tightly.

“Teacher….”

Mok Seongha called him. Kim Jinkyung answered yes with his eyes closed.

“…Teacher….”

“…Yes.”

“Haa…. Teacher….”

“Why on earth….”

Kim Jinkyung turned his head and froze. The man was looking down at him. His eyes seemed to be filled with excitement as he called out to him.

“Teacher..”

A soft voice leaked out from between his blood-soaked lips. Kim Jinkyung’s face flushed. The sensation of his genitals rubbing against his palm became even more vivid than before. The liquid that had begun to flow wet his fingers. The burning sensation on his palm startled Kim Jinkyung and he tried to pull his hand away. At that moment, Mok Seongha’s eyes lit up.

“Don’t pull away.”

It wasn’t a request or a plea like before. It was a command imbued with the authority of a predator. He gripped Kim Jinkyung’s wrist and continued softly.

“Continue.”

Kim Jinkyung nodded slowly. The man’s large hand overlapped his, as if trying to learn every movement.

Kim Jinkyung moved his hand again. The man’s breathing quickly turned ragged. His palm grew hotter. It wasn’t a mere illusion. It was real heat. Kim Jinkyung realized it came from friction. The rough surface of his penis scraped against his palm.

As the man’s arousal took on a clearer shape, his desire intensified. Mok Seongha clenched his teeth, and the area beneath his chin tightened.

He started to rock his hips up and down. The movement was far rougher and more ferocious than before.

Kim Jinkyung couldn’t pull his hand away. He couldn’t move. Mok Seongha placed his hand over Kim Jinkyung’s and rubbed his hard, swollen member. Rather than letting Kim Jinkyung assist with his hand, it felt as though he was having intercourse with it.

“Ugh… Teacher…”

A voice soaked in pleasure groaned into his ear. Feeling a tight pull beneath his hand, Kim Jinkyung’s toes curled. Sweat ran down Mok Seongha’s forehead and fell into his eyes.

Jinkyung blinked as tears streamed down his cheeks along with the sweat.

Suddenly, Mok Seongha’s breathing grew even rougher. The beast that scented blood surfaced. Aroused hunger filled his golden eyes.

Mok Seongha frantically arched his back. His member slid into Kim Jinkyung’s palm. Kim Jinkyung gasped and trembled. Unable to withstand the force of the thrusts, their overlapping hands slid down near Kim Jinkyung’s stomach. The man’s thick penis rubbed against his abdomen. The man’s desire was unmistakable. Kim Jinkyung’s eyes filled with fear, unaware of his own arousal.

“…Teacher.”

Through his blurred vision, Mok Seongha came into view. Kim Jinkyung barely managed a trembling “yes.”

“I’m sorry. I’ll do it later…”

A few broken words followed. Then sharp teeth sank into the back of his neck. Before he could scream, a spurt of hot liquid soaked his palm. The man thrust his hips forward several more times, his mouth tightening. A large amount of semen overflowed between their overlapping palms and spilled onto Kim Jinkyung’s stomach. It ran down his skin, like hot water poured along his spine.

“Haa… haa…”

Blood seeped from between the man’s lips. Kim Jinkyung was too shocked to notice the blood trickling from the nape of his own neck where he’d been bitten. The man lowered his head and licked Kim Jinkyung’s neck.

“…Huh.”

Kim Jinkyung swallowed a startled groan. Mok Seongha licked his neck thoroughly. Each time the large red tongue dragged over his skin, Kim Jinkyung barely managed to hold back a moan.

“…Stop it. Now.”

Even after he said that, Mok Seongha continued licking the wound, as if he couldn’t hear the human’s words. After a long while, Mok Seongha finally called out, “Teacher.” The man’s voice vibrated through his throat and sent a tingling sensation through him.

“Review.”

“…Huh?”

Kim Jinkyung didn’t understand at first and asked back. Only when the man’s thick, rough penis slammed into his palm again did he realize what he meant.

“No. Now, alone…”

Realizing the danger too late, Kim Jinkyung tried to rise, but the beast, heavy beyond reason, clung to him and started to move his waist. The man, with his frightening ability to learn, rubbed his penis against Kim Jinkyung’s palm with even greater precision and persistence than before.

In the end, that day, Kim Jinkyung had to help his student review until the skin of his palm swelled red.
