It felt like something that had no business being inside him was being forcefully wedged in. Every time something cold pried him open from within, it felt like his lower body was about to come undone. The intruding stem kept pushing in, rubbing and softening his inner walls with relentless thrusts, as if carving out a path for itself.
The stem, which had been carefully gliding along every fold, pushed in deeper. As it dug around with rough strokes, it struck a protruding, hypersensitive spot. Eun-jo let out a sharp gasp, his head snapping back.
“Hahhh…!”
The moment it felt those subtle, trembling spasms deep inside, the stem began to grind insistently against that sensitive area. Firm pressure followed by rapid tremors made his vision flash white, and breathy moans escaped him uncontrollably.
The now pliant inner walls were penetrated even further. Without him realizing it, five vines had twined together and were now plunging in and out of him. With every push and pull, his insides stretched smooth—completely unfolded—and when they withdrew, it felt like they were gnawing on him from within.
“Huh, uh, ah, ahhh…”
Noticing the change in Eun-jo’s moans, Jung Tae-seok lifted his mouth from Eun-jo’s chest. A thin, glistening strand of saliva stretched between them.
“Fuck, are you seriously getting off from this?”
As if punishing him for his incessant moaning, Jung Tae-seok sank his teeth hard into Eun-jo’s shoulder.
“Hng! Ah—ahh!”
“Teacher, huh…”
He couldn’t hold back any longer. The moment he yanked down his own school uniform pants, his fully erect cock sprang free. His lower half had been leaking for a while now.
“Teacher, ugh… my cock hurts.”
“Ah, uh… no…”
“I wanna put it in. Fuck, it feels like I’m gonna explode.”
The slick stems, which had slipped out for a moment, found his entrance again—then began prying it open. The cruel stretch of his tender rim made Eun-jo cry out.
“Huhhhh! Ah—ahh!”
The tightly clenched entrance was forced wide, exposing the flushed pink inside. Even then, slick fluid kept dribbling out from his inner walls.
With the last shred of sanity clinging to him, Jung Tae-seok stared at Eun-jo while stroking himself. His eyes were pleading, desperate—begging for permission.
“Teach me. Please… I want to shove it in deep and come inside…”
He whimpered, grinding his hips as he begged. Despite the pitiful look on his face, the thick, swollen shaft between his legs throbbed eagerly.
“Teacher…”
At his desperate call, Eun-jo flicked his eyes about nervously before speaking with hesitation.
“If I say no… will you stop?”
“I will.”
Gasping heavily, Jung Tae-seok took a shaky step back.
“It’d hurt you if I forced it.”
“I told you… it’s hard…”
“It’s so fucking hard. I feel like I’m gonna die…”
Grinding the words through clenched teeth, he brought his hand to Eun-jo’s lips and gently rubbed his lower lip. His voice trembled.
“I can’t help it… I lose control when I look at you. What am I supposed to do?”
His whole body felt like it was falling apart. Every breath was a struggle; even his bones felt like they were aching. Every inch of him craved the man in front of him. He wanted to bury himself inside that tight, twitching hole and thrust until his body broke.
But despite his primal urges, a warning screamed in the back of his mind—he mustn’t hurt him.
“You’re going to get wet again, aren’t you?”
“……”
“Answer me. Now. Teacher.”
He was at his limit. As he pressed harder against Eun-jo’s lip, Eun-jo let out a soft moan.
Eun-jo’s gaze flitted anxiously, probably because of the vines still binding his body. After catching his breath, he finally gave a small nod.
“Ah, don’t—don’t hurt me, hnn….”
The moment he got permission, he cupped Eun-jo’s cheeks and pulled him into a kiss. Their lips crashed together, and his tongue shoved in desperately. It plunged so deep it nearly reached Eun-jo’s throat, forcing a sharp gasp from him—huup.
At that same moment, the swollen head—nearly the size of a child’s fist—pressed into the stretched-open entrance.
“……!”
The loosened rim allowed easy entry, but it didn’t make the stretch any less brutal. The force of it tore through him like a blade, and Eun-jo’s eyes flew open. He could feel it all—every ridge, every vein of the cock pushing through him.
Jung Tae-seok swallowed his moans as he drove in deeper, carving through the clenched inner walls. The moment he hit another tight ring, Eun-jo thrashed his head in a panic. But Tae-seok didn’t stop—his tongue coaxing, he shoved himself in to the base.
“Hnnngh…”
“Haaah, fuck…!”
Fully sheathed, his pubic bone pressed against Eun-jo. Tae-seok groaned, breath hot. It was molten inside—like his whole body was sinking into a furnace. How the hell can it feel this good? Trembling with bliss, he gripped Eun-jo’s waist and pressed even deeper, grinding his cock against the tightest spot.
“Ahhh, haah…! Aah…”
Eun-jo squirmed, feeling like his lower belly might explode. Tears streamed down his cheeks. Tae-seok leaned in and kissed the corner of his eyes.
“Can’t have you crying already.”
Thud! His cock slammed in again, nestling between the soft swell of Eun-jo’s ass. The sudden impact made Eun-jo’s eyes roll back, mouth agape as he trembled violently.
He couldn’t even scream. His stomach bulged, and a deep ache spread inside. Before he could adjust to the pain, Tae-seok yanked him back and slammed in once more.
“Hngh! A-Aah! It’s tearing—ah!”
“Haaah, Teacher… fuck, it’s so good…”
He didn’t have a shred of control left—just raw, instinctive thrusting, like someone having sex for the first time. All he could do was fuck this hot, dripping hole over and over again.
Like a toy, Eun-jo was impaled and yanked back, again and again. Slam, slam—each time his cock buried itself, Eun-jo screamed and thrashed his head.
“Ah—ahh, ah…! Nnngh!”
The relentless pounding, like he was emptying every drop of lust, only sharpened the pleasure. The vines binding him, the obscenely gaping hole—it all blurred away. Nothing remained but Tae-seok’s cock, stirring him up from the inside.
“Nngh, Tae-seok, ahh! This—this…!”
Eun-jo’s hands flailed, and the vines gripping his wrists melted away. Free at last, he clung to Tae-seok, wrapping his arms around him.
Their bodies pressed together, not even a breath of space between them. Clinging like he was hanging from a cliff, Eun-jo sobbed. Tae-seok’s cock swelled even bigger from the tight squeeze. With each thrust, the inner walls scraped and dragged, sending waves of pleasure crashing through them both.
“Ah—aaah! Ngh, ahh…!”
“Haaah… take it all, Teacher.”
Normally, Tae-seok would’ve dragged it out, teasing him until he cried. But now, he was like a student in the throes of his first time—right on the edge, unable to hold back. The way Eun-jo’s insides clenched around him sent him reeling. He pulled his hips back and slammed in hard.
As if to prepare for the climax, the vines stretched the entrance wider. The delicate folds spread completely, revealing the slick, open hole. Tae-seok drove in to the hilt with a low grunt and wrapped Eun-jo in his arms.
“Hnngh…!”
His cock twitched, and thick, hot cum erupted inside—so much it filled him to the brim, even pushing up into his belly. Eun-jo clutched his stomach, trembling as he neared his own climax.
And then—
“H-Huh…?!”
Without warning, vines slithered down and coiled tightly around Eun-jo’s cock. They wrapped him up completely, hiding the pale pink shaft from view—as if forbidding anyone else from seeing it. The tendrils slid up toward the tip.
Eun-jo’s face drained of color. Before he could beg them to stop, one thin vine slipped into the tiny slit.
“Ah, ah…! Aahhh…!”
Eun-jo screamed, his body writhing in agony. The sensation of the thick stems forcing their way into that narrow hole was excruciatingly vivid. It was far more unbearable than just being stretched open. Overwhelmed by the pain, Eun-jo clawed desperately at Jung Tae-seok’s back.
“Ughhh! Tae-seok, Tae-seok, ngh…! Don’t—huh, please…!”
With a face twisted in ecstasy, Tae-seok kissed him and gazed at him like he was the most precious thing in the world.
“You can’t cum if you’re going to teach me.”
“Huh, please, please…! Hnng, ah…”
Cupping Eun-jo’s flushed mounds in both hands, he murmured lowly,
“If you cum this sloppily, what are the students supposed to think?”
“Ahng, ah, ahh…!”
“Did you drip like this even during class, huh?”
Clicking his tongue in regret, Tae-seok lifted him up. If I’d known, I would’ve taken you sooner. He turned Eun-jo over and laid him face down on the desk.
As his lower half—his slit still sealed—pressed against the cold desk surface, Eun-jo’s vision went white. Gasping for breath, he trembled as Tae-seok bit down on his earlobe and whispered,
“You’re only allowed to cum from the back, Teacher.”
He plunged his now fully erect cock into the cum-slick hole, exhaling a drawn-out sigh.
“Haa, so good…”
The hole, once clenched shut, was heavenly—but this one, now soaked and loosened by his own cum, was just as tempting. As the inner walls gripped his cock like a kiss, he began to thrust in earnest.
