I Became a Monster in a T*ash Game

My brain felt like it was crackling. Muhae bowed his head in silence, breathing in Joo-o’s heady scent.
The more he tried to calm himself, the hotter he burned below. Even if he weren’t submerged, he’d be soaked through by now.
He wanted to rub himself everywhere. To plunge, to press, to fuck like a beast.
A desire stronger than a whirlwind surged up, clenching his jaw so tightly it ached. At the last moment, terrified he might bite, Muhae merely pressed and rubbed his lips everywhere.
Still, he couldn’t withdraw his hand from between Joo-o’s thighs. He savored the tremors of Joo-o’s body as his fingers traced the soft skin.
Using the warm water as lube, he touched him there again and again, and the tightly closed folds slowly began to loosen.
“Mm.”
Joo-o squirmed and spread his legs. Even as he nodded, his eyes were glazed.
Every time Muhae’s finger brushed the entrance, Joo-o’s tongue peeked out, plump and moist as if begging to be tasted.
“Want me to touch you more?”
His cock half-erect from the explicit view, Muhae almost sneered. Though no one was around, he whispered in Joo-o’s ear.
Joo-o nodded helplessly, face flushed with feverish lust.
As Joo-o softened, the opening melted around Muhae’s probing finger. He slid in without resistance.
“Yes…!”
Joo-o trembled in tiny bursts, but made no move to close his legs. He breathed unevenly yet surrendered to Muhae’s hand.
Soon the hot, slippery inner walls gripped Muhae’s finger. Each tremor felt like a sweet protest.
“Do you like this?”
Like some twisted pervert, Muhae asked. He knew how ridiculous it sounded, but Joo-o, eyes nearly shut, murmured soft, indistinct sounds in response.
Watching Joo-o’s head dip and rise against him, Muhae pressed further. The lower half that had ballooned now felt stretched to its limit. He curled his finger and greedily explored.
“Ugh… ahh…”
Inside felt impossibly tight, as if it had never been used, yet with each motion created just enough space.
Had it always been so pliant? It squeezed hard, yet swallowed every inch he pushed in.
Next, his middle finger edged in beside the first. Splitting them like scissors, he stretched the entrance taut.
Joo-o let out a whimper, searching for Muhae’s hand. When Muhae patted his shoulder, Joo-o gripped that hand and gave a soft laugh.
“Shall I stop?”
He’d long since lost the desire to, but asked anyway.
Joo-o shook his head and returned Muhae’s hand to his own body.

“How did you know what I wanted?”
Muhae asked, voice almost threatening with restrained need.
For a moment, Joo-o’s clouded eyes sharpened. He gave a blissful grin.
“Mating.”
His red eyes curved prettily. At the sight of those wet, glossy lips, Muhae felt the last semblance of restraint shatter.
…A bath to rest? A moment’s respite? Those were long-forgotten pretenses. Muhae lifted Joo-o and sat him astride his thighs. When his fingers slipped out, Joo-o whimpered, but that sound was swallowed by the water.
Muhae captured Joo-o’s soft tongue with his mouth—tasting the slippery membrane, drawing in that cheeky tongue—and found the flavor sweet.
As Joo-o mimicked him, tongue dancing, Muhae’s own inexperience led to drooling.
Joo-o’s heart pounded audibly. Muhae spread Joo-o’s buttocks to reveal the relaxed hole.
He stealthily rubbed his stiff cock against it. The tender entrance parting and gripping the glans sent a fuse spark in his mind.
Licking his trembling lips, Muhae slid underneath Joo-o. That thick shaft buried halfway.
“Ugh…!”
The hot, tight walls clamped him wholeheartedly. His vision shook and the bathroom lights shattered like stars.
Unlike Joo-o’s panting pleas, Muhae couldn’t even moan—only his reddened eyes and held breath gave him away.
He almost came before fully in. Joo-o’s soft, suckling flesh pressed around him with overwhelming intensity.
“Good… mm, Jin Muhae.”
Joo-o panted into his ear, as if instinctively knowing the signal to drive him on.
He was foolish, yet clever; clouded, yet startlingly lucid at times.
Slowly, Muhae explored between Joo-o’s legs. The smooth skin, now taut without a single fold, greeted him.
Fortunately, there was no blood—no tearing despite the impulsive thrust. Joo-o’s eyes rolled back, tongue peeking, but he was fine.
Muhae pressed the head of his cock deeper against the unyielding interior. Joo-o, mouth agape with a hiccup of pleasure, finally sank fully onto Muhae.
“Ahk…!”
He impaled him to the hilt. The slippery walls swallowed every sensitive ridge.
Gasping, Muhae pulled his hips back then slammed forward with a loud smack. Water splashed and Joo-o convulsed in spasms.
“Mm… huu…”
Joo-o’s dazed, moaning face looked so ripe Muhae nearly bit his cheek. Battling his own rising violence, Muhae plunged harder.
A sharp bliss radiated up his spine. He’d always wanted this: to bury himself in that sultry body again and again.
Maybe that’s why he’d been angry whenever Joo-o lingered in his mind—he didn’t want ◈ Nоvеlіgһт ◈ (Continue reading) to admit his own arousal.
“‘Course. He’s smarter than you are,” came Teacher Jeong’s words, once wounding Muhae’s pride, now an absolution for this shameless act.
Trembling with pleasure, Muhae clutched Joo-o’s hips and thrust again. Every in-and-out sent warm water surging up.
Joo-o, unable to withstand the stimulation, shook his hips. Yet he called only for Muhae, murmuring into his lips so that the vibration hummed inside Muhae’s mouth.
“Mm…!”
Another tight clench inside, and Muhae finally released, spurting thick ropes into Joo-o.
They paused, mouths joined, drowning in heavy breaths and deep satisfaction.
“Ugh… the water’s dirty now.”
Joo-o murmured without breaking the kiss. Muhae smirked and lifted him out.
As he withdrew, water and cum dripped down. Despite multiple climaxes, Joo-o’s cock stiffened again.
“I want more.”
Unperturbed by the risk of slipping, Joo-o let go of Muhae’s hand and spread his own cheeks.
“I’m losing my mind.”
Even as an apology, his cock stood rock hard. Muhae pressed him against the wall and rammed in once more.
Their panting echoed in the cavernous bathroom. Cloudy bathwater dripped milky white onto the floor.
Contrary to expectations, the two returned to Goryeo City in a single day.
Muhae gave up on riding the bike back. Blowing the last of his budget, he rented a short-range flyer.
It was wise—no need to risk the dangerous roads. They’d live like beggars until the next assignment.
Surprisingly, Joo-o didn’t mind the reduced meat rations. Perhaps still in a daze, he’d agreed when Muhae asked.
“Thinking it over, I’m not okay with this.”
“Too late.”
Joo-o poked at Muhae’s cereal while staring at an empty Fruit Tornado box.
Fiddling with the box didn’t sweeten the taste, yet he kept touching it with every bite.
“Have you interpreted the research?”
“Not yet. I’ll hit the electronics market tomorrow.”
Instead of a scoff, Muhae got a proper answer, and Joo-o’s face brightened at once.
He guzzled the remaining milk, dashed to the study, and soon reappeared with arms full of impulse purchases.
“Want some, Jin Muhae?”
Holding meat skewers still warm, Joo-o lit up. Muhae sighed softly.
“Give me one.”
With a grin, Joo-o split half his stash and handed it over, then hummed his way back to the TV.
—Tok tok pang pang, new flavor popping rainbow stars♪
“Tok tok pang pang, new flavor yi-um yum yum stars.”
Singing the jingle, Joo-o devoured his skewer. Muhae watched a while, then returned to the half-translated document before him.
