“Kgh, haah….”
Just as expected, the shaft of his cock met the hot, moist mucous membrane. Frowning slightly, Mu-hae looked down to see him, eyes flushed with heat, taking someone else’s member into his mouth.
The thing that had been sleeping quietly inside his underwear just moments ago expanded in size, becoming massive in an instant.
Slurp. As soft lips tightened and sucked the shaft, veins bulged across the organ like a temperamental beast.
“Suddenly, haah, it’s catching fire and going wild.”
“Mmm, uu.”
It was always like this. True to his nature as a Hungry Ghost, he tried to put everything in his mouth whenever he got the chance.
Jin Mu-hae, who had tried to stop him a few times at first, had now let go, as if to say, do as you please. To be honest, the way he focused so intently on him was quite cute.
It was also amusing how he mumbled incomprehensible things whenever Mu-hae spoke to him in the middle of it. Just watching the fellow struggle and moan while holding his member provided a stimulation that felt as if his lower half were melting.
Lick. A red tongue peeked out, wrapping around the side and licking it. A raw pleasure surged through his spine like an electric current.
Without realizing it, Mu-hae gripped the back of the other’s head, which was pressed tightly against him. Even that touch seemed to please him, as he smiled so wide his eyes closed, practically losing it.
“I never taught you this.”
It was true. Whenever they dove in first, it was always Joo-oh.
Even though no one was watching, Mu-hae felt the need to explain—that he hadn’t corrupted a perfectly normal and innocent kid.
Joo-oh’s mouth trembled as if he were giggling. Goosebumps rose to the top of Mu-hae’s head, and a vein popped on his forehead.
It was strange. When he sucked him, it wasn’t just a matter of getting aroused. A stimulation surged through him that made his spine chill, and his heart began to beat in a rapid rhythm.
The pleasure reaching its peak resembled the vitality of the times he had run through the dangers of death. As pleasure filled him to the crown of his head, Mu-hae’s jaw tightened until it hurt.
Moving his hips slowly, Mu-hae suddenly thrust the tip of his cock into the twitching throat.
He did it because he was nearing his limit. He thought it might make the other gag and spit it out.
He didn’t know what this damn brat was thinking, but he kept swallowing whatever was shot into him; even when Mu-hae later put his fingers in to stir, there was nothing left in his mouth.
Since the party involved liked it, he usually let it slide, but this felt like a bit of a blow to his conscience. That’s not something you eat. That’s, I mean…
“Haah, huu…!”
Crazy. Joo-oh didn’t gag. The throat, which should have reflexively expelled a foreign object, opened and tightened smoothly, as if it were an organ designed specifically for him.
A sensation like sparks flying before his eyes. A slippery pressure. At the sound of the uu, mmm noises, the member being sucked trembled, and his lower abdomen hardened in a spasm.
Letting out a pained moan, he simply came. While his hips were still shaking, he realized immediately.
Once again, he had lost the psychological war with Joo-oh, who tried to lick up the seed. Even if he let him suck the bottom now and stirred the mouth with his hand, the brat would just drool and love it.
“Who, haah, told you to eat this, huh?”
“Mmm, hnnng.”
“Who was it that said they’d be obedient?”
“Me. Instructor.”
It seemed the act of playing the trainee was still ongoing. Mu-hae tapped the smooth cheek with the tip of his index finger and pulled his drenched member back.
He felt so hot that it seemed as if steam were rising from his lower half. Mu-hae lifted the fellow who had been crouching below the sofa and pulled him into his arms.
He bit the neck of the one clinging to him like a koala. A sweet, fragrant scent of skin tickled his nose.
“Haha! Ha!”
Whether it tickled or not, Joo-oh burst out laughing. Then, as a tongue touched his skin, he flinched and stopped for a moment.
The body held in his arms became noticeably hot. Even if he wasn’t a normal being, was it okay for his body temperature to rise so instantaneously?
He didn’t know. He could only feel that the other’s skin was damn sweet and soft. Mu-hae savored the scent, nibbling and licking various spots on his neck.
The scent of the same shampoo mixed with a unique body odor. He didn’t know why it felt so good. He bit and nipped so frantically that Joo-oh began to dangle his legs.
“Jin Mu-hae, Instructor. I like it. Nng, h, I like it.”
It was definitely the clothes that had set him off. As soon as Mu-hae loosened the tie he had worn with the shirt, Joo-oh rubbed his cheeks against him with eyes that didn’t know what to do with all the joy.
“What to do. I’m not fond of trainees who only cause trouble.”
Unable to withstand the struggling, Mu-hae set him down on the sofa, and Joo-oh quickly reached out and hugged him.
Only after they collapsed together did a sense of leisure return to Joo-oh’s face. His red eyes curved into a smile as he whispered in Mu-hae’s ear.
“It’s okay. I can just be scolded.”
“Is that the attitude of someone being scolded?”
“I was wrong. Instructor. I’ll do whatever you teach me.”
The suggestive voice made his lower half ache as if it were being squeezed. The gap in the zipper, barely lowered, was far too narrow for a member that had grown as large as it could.
“Haah… wait.”
Training a wild pet always started with ‘wait.’ Mu-hae pulled out the tightly fastened belt with a snap and, with a clink, undone the trouser buckle and lowered the front.
As if he had never pretended to reflect on his actions, Joo-oh’s mouth parted. Mu-hae pushed his chest down and held up an index finger.
“Who sucks while they’re being punished?”
“Isn’t that the punishment?”
“You pant with pleasure while being punished?”
Finding no words to argue, the brat just licked his lips regretfully. Mu-hae peeled the hands off his back one by one and crossed them.
Then, he snatched the tie still held in Joo-oh’s hand and pressed it against the gathered wrists.
Tight, snap!
The piece of cloth that had been a symbol of a civilized and socialized human just moments ago instantly became a binding rope for a disobedient trainee.
Look at that damn face. He had an excited expression, as if he were about to say, Haha! I love being scolded!
That brazen face was still cute. Mu-hae kneaded the fellow here and there, who tried to rub his head and cheeks against him regardless of his tightly bound wrists.
As he slid his hand under the T-shirt, rubbing from the lower abdomen upward, the chest cavity twitched and heaved deeply.
“Ah, eu.”
Joo-oh panted, his hips trembling slightly. Then, after confirming what the human lying on top of him was wearing, he burrowed into the embrace with a face of unbearable joy.
“Scold me, scold me.”
“You show no sign of remorse; it seems we’re back to square one.”
“No. That’s not it. Hnnng, I’ll reflect.”
After tapping his forehead once like a knock, Mu-hae stopped his hand on the chest. As he simply placed his fingertip on the already prominent bud, Joo-oh shook his head as if anxious.
“What did you talk about. At the electronic store.”
At the tedious, lingering interrogation, Joo-oh stopped panting and laughed.
“Mmm. It’s not a secret. The thing we talked about before.”
As soon as he leaked a tiny bit of information, Mu-hae grabbed and twisted the hard nipple. Hieuk, nng, as Joo-oh shuddered with pleasure, he blinked as if he had learned something new.
“That Director Gil isn’t moving, nng, and is staying on Starlight Road.”
Finally, the story he wanted to hear leaked through the teeth. Seeing that Joo-oh had realized this ‘punishment’ was actually the price for disclosure, he played with whether to open his mouth or not.
Joo-oh wriggled his legs and stripped off his loose pants. To ask for more touching, he rolled up the T-shirt he was wearing and bit it firmly in his mouth.
With a flushed face that practically begged to be devoured, it was hard to overlook without rubbing his eyes and biting his lips.
Mu-hae slid his tongue into the mouth that only knew how to say annoying things. The interior of the mouth, which opened smoothly, was wet and warm, making his lower half tighten instantly.
“Reporting and then stopping… it seems you weren’t scolded enough.”
“Nng. I think I’ll come to my senses if I’m scolded more.”
Bullshit. Given how often he’d poked him with his cock, he’d never seen Joo-oh ‘come to his senses.’
Still, it was a pleasant thing to hear. Just like the lips that bit and pestered him.
As he moved his hand down, he touched the slightly slippery, wet perineum. While he played with the smooth, tender skin, rubbing it over and over, the mouth that had bitten, sucked, and rubbed him panted continuously.
Ah, ah, nng, Joo-oh’s words gradually transformed from language into a collection of meaningless sounds. As he reached a bit deeper, the hole that had been moving and pulsing opened softly without the need for loosening.
After scratching the inner walls a few times and pressing firmly, Mu-hae pinned down the trembling hips. Shortly after, splat, he came onto Mu-hae’s hand.
As he smeared the liquid, which was as slippery as lubricant, on the bottom, the other’s chest heaved greatly. Jin Mu-hae rubbed his member, which had grown terrifyingly large again in a short time, and then thump, pushed in from the tip.
“Hik, huuu….”
Along with a small moan that was barely audible, the inner walls gripped him. The tight pressure made the fine hairs on the nape of his neck stand up.
Mu-hae took a sharp breath. A body that reacted just as well no matter when he messed with it only added to the already accumulated heat.
Thud. It was no longer difficult to bury himself up to the root inside him. As soon as he pushed past the curved structure and thrust upward, Joo-oh’s eyes widened and he convulsed violently.
“Jin Mu, hack, hnnng…!”
“Who, haah, calls the Instructor’s name so carelessly.”
“Instructor, uuunng, Instructor.”
He was a fellow who loved it no matter where or how he was shoved, but he reacted especially well when pressed and rubbed firmly.
Thanks to having his arms tied beforehand, Joo-oh, unable to flail, lay quietly and groaned.
He wanted to bite those flushed cheeks and shake him until he fell apart. He felt the impulse to nibble on the earlobes and press his chest down with a pillow to see him struggle.
Mu-hae didn’t want him to get hurt, which was a truly peculiar emotion.
