He looked forward to the pleasure that always came laced with a sharp, stinging pain. It would spread him open, sink deep inside, and slam right into that sweet spot with its thick, swollen tip. The mere anticipation sent a shiver through Eun-jo, a soft moan slipping from his lips.
But no matter how long he waited, he didn’t feel it touch him.
“Huh?”
Lifting his head, he found Jin Mu-seong stroking himself instead.
“Kinda wanna rub it on you first. Is that okay?”
“…What did you just say?”
“Clause 2—All physical contact requires Yeo Eun-jo’s consent.”
That wicked grin of his stretched wider.
“So come on. Give me permission, baby.”
“You’ve lost your damn—”
Determined to hear a yes, Jin Mu-seong gripped himself tighter and egged him on.
“Hmm?”
“Ugh, just—please!”
Eun-jo felt like dying from the shame alone. Thank God the room was dark. If the lights had been on, his face would’ve been a humiliating shade of crimson.
“Just put it in already…”
Of course, someone like Jin Mu-seong—with his absurdly sharp eyes and enhanced senses—could see right through him. He smirked down at Eun-jo’s flustered face, clearly enjoying the sight. The worse Eun-jo looked, the more twisted his expression got—the more Jin Mu-seong liked it.
“Put it in.”
“Please… put it in.”
“What, no ‘pretty please’?”
That extra little jab made Eun-jo’s eyes snap open, both aroused and pissed off.
“God, you’re so—!”
Before Eun-jo’s temper could flare, Jin Mu-seong grabbed his ankles and lifted them up, folding his body nearly in half. Then he buried his face between his thighs.
The moment his tongue slipped past that tight ring, Eun-jo gasped aloud. The firm tip of his tongue circled gently, teasing the sensitive inner walls.
“H-Heuuk…!”
It was like someone had laced him with an aphrodisiac—his body heated up instantly. His insides clenched, his lower belly pulled tight. Hands trembling, Eun-jo grabbed fistfuls of Jin Mu-seong’s hair, moaning uncontrollably as the pleasure built.
Jin Mu-seong took his time, lapping up every drop like it was something sweet. When he finally pulled away, he grabbed Eun-jo’s thighs and spread him open, completely exposing him.
Patience clearly wasn’t his strong suit either. As the swollen head pressed against his entrance, Eun-jo’s hole twitched, as if begging him to get on with it.
“Haa…”
And just like that, he thrust in—all at once.
Eun-jo gasped as he was split open, the thick cock stretching him impossibly wide. No matter how many times they’d done this, he still couldn’t get used to it.
He felt completely filled, like his guts were being shoved aside. Jin Mu-seong ran a hand down his waist as the tight ring clamped down around him.
“Breathe.”
“Uhk—hnngh.”
It felt like he was being ripped in two. The pain stole his breath, his body overwhelmed by the sheer size of it.
Why the hell is it always this big…?
Maybe it was the alcohol, but even something like this—his boyfriend being too damn big—made him want to cry. His eyes filled with tears, frustration bubbling up.
“Heuhh… aahh…”
“Does it hurt?”
Alarmed, Jin Mu-seong started to pull out, but Eun-jo clung to him.
“No… ngh! Hngh, it feels good…”
As their bodies pressed together again, he sank even deeper. When the swollen tip scraped along his inner walls, a jolt of pleasure shot through him like electricity.
It hurt—but it also felt like hanging off a cliff by the fingertips. That terrifying, dizzying high was addictive. As much as it overwhelmed him, the way that thick girth filled him perfectly left him breathless with satisfaction. Gasping, Eun-jo reached for the collar around Mu-seong’s neck and gave it a tug.
Jin Mu-seong leaned in without resistance, and Eun-jo pulled him into a kiss. Mimicking his earlier teasing, Eun-jo bit gently at his lower lip—and was rewarded with a tongue slipping into his mouth.
“Mmh… mmm…! Nnngh…”
The kiss turned ravenous. Tongues tangled, saliva mixing, moans swallowed. As their lips melded, Jin Mu-seong slowly started to move his hips again.
Wet skin smacked together with sticky, obscene sounds. They were practically fused at the hips, thrusting and pulling apart like one heaving mass. His cock plunged deep with every thrust, then pulled out with a wet pop before slamming back in again.
The walls that had clenched so tightly around him now loosened, letting him in more easily. The way their bodies stuck together—it was like their mouths, kissing. Sweet and intimate.
Jin Mu-seong let out a slow, languid moan.
“Haa… baby.”
The word “baby” felt oddly out of place.
Blinking up at him through heavy lids, Eun-jo caught the soft smooch of a kiss landing on his eyelid.
“I want to go deeper,” Jin Mu-seong murmured.
His fingers gently stroked Eun-jo’s lower belly, the very spot that would soon bulge as if he’d been knocked up.
“Will you let me?”
“Hnnh, ugh… And if I say no…?” Eun-jo snapped back with teary eyes, the fight still flickering in his voice.
Jin Mu-seong clearly got the message. He leaned in and licked the tears trailing down Eun-jo’s cheek with a wet smack.
“Then I’d have to pull out. Rules are rules, after all.”
Eun-jo’s big, trembling eyes flickered uncertainly. That innocent expression—like he truly believed Jin Mu-seong would actually stop—nearly made him lose it.
Where the hell did this perfect little thing even come from?
He wanted to devour all of it—the fire in those tear-brimmed eyes, the flushed cheeks, those sweet lips that sometimes called him “baby.” Everything. Every last piece of him. He wanted it all.
Completely unaware of what was going on in Jin Mu-seong’s head, Eun-jo hesitated briefly… then gave a tiny nod.
“Okay—Haaah!”
And that was all it took. Jin Mu-seong immediately hoisted both of Eun-jo’s legs onto his shoulders.
“……!”
And then he slammed it in.
His cock plunged deep—so deep it felt like a fist had punched into his gut. The impact knocked the air right out of Eun-jo’s lungs. His eyes flew wide open.
The tight, narrow walls were stretched mercilessly as the swollen tip shoved straight past the first ring of muscle and pushed into the next. Gasping, Eun-jo grabbed the collar around Mu-seong’s neck, choking on the sensation.
Ironically, the more he pulled the leash, the more their bodies pressed together—and the deeper Jin Mu-seong sank in. His cock burrowed in fully, spreading him open and pushing past the entrance to his colon. A low groan rumbled from his throat.
“Damn… that’s deep.”
Their hips locked tight. Jin Mu-seong began to move again, slowly dragging himself out and thrusting back in. Each stroke stretched Eun-jo wider, grinding open the tight entrance to his colon with the thick tip of his cock.
“Hnnngh—ahh… haaah…!”
Every time that deep, buried sweet spot was struck, Eun-jo’s toes curled. His whole body was a mess of filth and heat. He’d just been crying a minute ago, but now he was pulling the leash taut, moaning wantonly and begging for more. Each tug made the collar snap against Jin Mu-seong’s chest—and each snap only made him thrust harder.
“Now that I’m buried this deep… hnn, you like it?”
“Y-yeah… nghh…! Mmh…”
His toes pointed stiffly, thighs trembling. Wanting it even deeper, Eun-jo spread his legs further on his own. When he yanked the leash in time with the thrusts, Jin Mu-seong’s hips snapped forward harder, rougher.
The room echoed with the sharp slap slap of skin on skin. Jin Mu-seong groaned as he felt those greedy walls clamp down, sucking him in with every thrust. They were stuck together in every sense of the word—pulling apart only to slam back together again.
“Nngh, you’re so tight… baby…”
He rammed the fat head of his cock deep into Eun-jo’s colon again, making his back arch in response.
“Haahhh…!”
“I wanna bury it all the way inside. Yeah? Can I?”
He panted, slamming into that sweet spot deliberately. His upward curve dragged hard against the inner walls, and Eun-jo screamed, thrashing beneath him.
Tears streamed down his face. He wanted to run—but he also never wanted this to end. The overwhelming pleasure made his body shake uncontrollably.
“I can put it all in, right?”
Eun-jo couldn’t even process what he was saying—he just nodded wildly, lost to the sensation.
“Yeah—uhh, mmmh—please! Just do it, aahh…!”
The moment permission was given, Jin Mu-seong grabbed him tight, locking their bodies together. Wrapping both hands around Eun-jo’s soft, round ass, he held him firmly in place and spread him wide open.
His flushed hole parted… and slowly, two heavy beads began to push their way in.
It wasn’t until then that Eun-jo realized what was happening. His eyes widened in panic as he gasped, flailing in alarm.
“H-Hiiiek…!”
“Ah… aah, nghhaaah…!”
His hole, stretched wide without a single wrinkle, greedily swallowed him whole. Every last inch slid in with ease. The overwhelming tightness made Jin Mu-seong let out a deep, guttural growl, his chest vibrating with satisfaction at being fully sheathed.
With his brow furrowed, he began to thrust again. Squelch, squelch…! His cock plunged deep, slammed all the way in, then pulled out only to drive right back inside. Every time he bottomed out and struck the entrance to Eun-jo’s colon, white flashes exploded in Eun-jo’s vision, his entire body shuddering helplessly.
His mind was a total blur. The only thing he could register was the feel of that thick cock thrusting in and out, pounding him senseless. Whimpering like a wild thing, Eun-jo clung to Jin Mu-seong by the leash. When another overwhelming wave of pleasure tore through him, he leaned up and bit Jin Mu-seong’s lips hard.
“Hngh… ah, aaahh…!”
Sensing he was right on the edge, Jin Mu-seong slammed in hard—brutal and unforgiving. Eun-jo’s hole, now stretched wide enough to swallow both heavy balls, twitched violently as it turned inside out slightly, revealing flushed, trembling flesh. At that exact moment, warmth filled his belly.
Liquid streamed out from between his legs in steady dribbles. It wasn’t even like cumming—it felt closer to losing control completely.
Again… again…!
Humiliation curled in his gut as Eun-jo squeezed his eyes shut. The shame of releasing again made his cheeks burn. Jin Mu-seong, who had lapped up even his shaky, ragged breaths, now trailed kisses down to the tear streaks on his cheeks.
The soft, wet sounds of kissing echoed through the dark room.
Buried against his chest, Eun-jo fought to steady his breathing.
“So that’s your… kink, huh?” he muttered, voice thin and hoarse.
In response, Jin Mu-seong gently nibbled his earlobe. But Eun-jo didn’t stop. He kept going, casting him a sideways glance.
The thick collar wrapped around Jin Mu-seong’s neck looked ridiculously good on him. He didn’t know what Jin Mu-seong’s preferences were, but this—this was definitely his thing. That realization made something clench low in his belly, and his hips gave an involuntary twitch.
Jin Mu-seong felt it. Even while still buried deep inside, he chuckled low.
“Whatever turns you on—that’s my kink.”
He pressed a soft kiss to Eun-jo’s forehead and whispered:
“Say the word.”
“……”
“I’ll do anything you ask.”
The filthy things he’d begged for earlier flashed through Eun-jo’s mind like lightning.
“How can someone be so…”
His voice trailed off, and he quickly shut his mouth. Normally, he would’ve said shameless, or blunt, and left it at that.
But this time, it was different.
How can someone feel this good?
Why do you match me so perfectly? Why do you move like you know exactly what I want?
Letting out a long sigh, Eun-jo covered his face with both hands. But it did nothing to hide the furious red burning in his ears. Jin Mu-seong narrowed his eyes again, the same knowing grin spreading across his face.
“From now on, you only drink when I’m there with you.”
