Chapter Text
“I’m cumming! Don’t stop… please… hyung…”
Five minutes earlier
The front door clicked open with a soft metallic sound as Jeongin finally managed to unlock it, shifting the weight of several grocery bags balanced between both arms. Plastic handles dug into his arms, and he let out a quiet sigh as he nudged the door shut with his foot.
The trip had taken longer than expected. Seungmin had handed him a surprisingly long shopping list before practically ushering him out the door, insisting they needed everything for dinner tonight. More importantly, he'd been oddly specific about one thing.
"Take your time, okay? Don't rush back."
It had been suspicious enough to make Jeongin raise an eyebrow. Seungmin wasn't usually the type to care how long a grocery run took, and the way he'd practically shooed him out of the apartment only made it stranger. Jeongin had considered texting him halfway through to ask what was going on, but curiosity got the better of him. If Seungmin was planning something, he'd rather find out the old-fashioned way.
So instead, he’d wandered the aisles a little longer than necessary, compared prices he normally wouldn't care about, and even stopped for a drink before heading home.
Now, with bags full of ingredients hanging from his arms, he struggled to kick off his shoes.
"Hyung?" Jeongin called out, nudging the front door shut with his heel.
No response.
He frowned.
"Seungmin hyung, can you come help me?"
Still nothing.
With an exasperated sigh, he set a few of the grocery bags on the floor, slipped out of his shoes, and gathered everything back into his arms. He headed toward the kitchen, expecting Seungmin to be waiting there with that annoyingly smug grin he always wore whenever he watched Jeongin struggle.
The kitchen was empty.
"...Hyung?"
Then he heard it.
A quiet sound from the hallway.
Not talking.
Not the TV.
Something... softer.
Jeongin paused, listening.
Another muffled noise follows, accompanied by the unmistakable creak of a bedframe.
His eyebrows had knit together.
Is someone hurt?
The thought has him moving before he can stop himself. He set the grocery bags on the kitchen counter and walked toward Seungmin's bedroom, concern replaced his earlier annoyance.
Jeongin froze in the hallway, heart hammering as the strange sounds drifted from Changbin's room. Concern pushed him forward until he stood just outside the slightly ajar door.
He leaned in, intending to knock or call out, but the moment he caught the real sounds, everything shifted. Low, breathy moans spilled out, unmistakably sexual. Jeongin's breath caught. He should have backed away, but curiosity rooted him there. Through the narrow gap he saw everything.
Changbin had his roommate bent over the edge of the bed, gripping his hips hard. Changbin's thick cock drove in and out with steady, powerful thrusts that made the bed frame creak. The roommate's face was pressed into the sheets, ass up, taking every inch while Changbin's muscular body flexed with each movement. Sweat glistened on Changbin's chest and arms, but his expression stayed flat, almost detached. His jaw was set, eyes half-lidded with something closer to boredom than lust. He kept pumping mechanically, like he was going through the motions rather than chasing any real pleasure.
Jeongin swallowed hard, unable to look away from the sight of Changbin's cock disappearing again and again into the stretched hole, the wet sounds of skin slapping skin filling the room. Changbin barely made a sound himself, just the occasional low grunt that felt more like effort than enjoyment. His grip stayed firm, but there was no spark in his movements, no hunger in the way he fucked. It looked like a chore he was finishing because he had started it.
The roommate moaned louder, pushing back against Changbin's thrusts, but Changbin's bored stare never changed. He kept the same steady pace, cock sliding deep with every stroke, yet his face showed none of the heat Jeongin expected. Jeongin felt his own pulse racing, caught between shock and the strange pull of watching something so raw and unfulfilling at the same time.
“I’m cumming! Don’t stop… please… hyung…” Seungmin's body jerked hard as his orgasm ripped through him. His cock pulsed untouched against the sheets, shooting cum across the bedding while his hole clenched tight around Changbin's still-thrusting dick. The moans turned into broken gasps as Seungmin's thighs shook, his ass pushing back instinctively even as pleasure flooded him.
Changbin didn't slow down or change his rhythm. He kept driving his cock in and out of Seungmin's spasming hole with the same steady, mechanical strokes, his expression unchanged. Even as Seungmin's cum-soaked body trembled beneath him and his hole fluttered around Changbin's length, Changbin showed no reaction. No grunt of satisfaction, no shift in pace, nothing.
Jeongin stayed frozen at the door crack, watching Changbin's thick cock keep sliding deep into Seungmin's cum-slicked ass. The wet sounds continued without pause while Seungmin whimpered through the aftershocks, completely spent, yet Changbin fucked him like it was just another task to finish.
Changbin let out a low sigh, his hips finally slowing to a stop inside Seungmin's still-twitching hole. He pulled his cock free with a wet sound, leaving Seungmin's ass gaping slightly from the sudden emptiness. Without a word, Changbin sat back on his heels and wrapped his own hand around his half-hard dick, stroking it with quick, efficient movements.
Seungmin collapsed forward onto the cum-stained sheets, panting and spent, his body limp after his own release. He didn't notice or care that Changbin had stopped fucking him. Changbin kept jerking himself off, eyes half-closed, focused only on getting himself off now that Seungmin had proven useless for the job. His grip tightened as he pumped faster, the head of his cock flushed and leaking pre-cum over his fist.
Jeongin watched through the crack, breath caught in his throat as Changbin brought himself to the edge alone. Changbin's jaw clenched, and with a few final strokes, his cock pulsed in his hand until he finished.
Thirty minutes later, Jeongin stood at the stove in the kitchen, stirring a pot of ramen as the smell of broth filled the air. Changbin had left right after he came, slamming the door on his way out with a scowl that made it clear he was pissed off. Jeongin kept his focus on the food, but his mind replayed the scene from earlier. The way Changbin had fucked Seungmin without any spark, then finished himself off with his hand.
Seungmin walked in a moment later, towel around his waist and hair still damp from a quick shower. He froze when he spotted Jeongin, eyes widening in surprise. "You're back already?"
Jeongin didn't look up from the pot. "I saw you." The words came out flat, like he was commenting on the weather.
Seungmin's face drained of color. He gripped the edge of the counter, mortified. "What?"
"You really don't know how to please your partner, do you?" Jeongin added, still casual as he tasted the broth and added a pinch of salt. "Changbin looked bored the whole time. He had to jerk himself off just to finish."
Seungmin stood there speechless, the awkward silence stretching between them while Jeongin continued cooking like nothing unusual had happened.
Seungmin shifted on his feet in the kitchen, cheeks burning as he tried to find the right words. "I-I mean, it's not like I'm bad at it or anything," he started, voice cracking slightly. "Changbin hyung always finishes, so I thought... I thought it was fine? He doesn't complain, and we... we do it pretty often."
He rubbed the back of his neck, eyes darting everywhere except Jeongin's face. "Maybe he's just quiet? Or maybe I miss something sometimes, but I don't know how to ask without making it weird."
Jeongin leaned against the counter, arms crossed, watching him with that same unbothered expression. "You're missing a lot. He wasn't even close to satisfied. You were the only one getting off properly."
Seungmin's mouth opened and closed a few times. "W-wait, how do you"
"Doesn't matter how I know," Jeongin cut in casually. "Point is, you need help. I can show you. Teach you what actually works."
Seungmin blinked, stunned. "You... you'd do that? Teach me?"
"Yeah," Jeongin said with a shrug. "No big deal. We can start whenever."
Seungmin stood frozen in the kitchen, the weight of Jeongin's casual offer still hanging in the air. His hands fidgeted at his sides while he stared at the half-chopped vegetables on the counter. "I... I don't know if that's a good idea," he muttered, voice low. "Changbin hyung and I... we've been together for a while. It feels wrong to let you teach me stuff like that."
Jeongin didn't push. He simply tilted his head and waited, arms still crossed. "It's your call. But if you want him to actually enjoy it instead of just going through the motions, this is the fastest way."
The silence stretched. Seungmin shifted his weight from foot to foot, cheeks burning darker by the second. He kept glancing toward the hallway where Changbin was probably still resting, then back at Jeongin. After another long pause he exhaled sharply through his nose. "Fine. Okay. Show me. But... only because I want him to feel good too."
Jeongin nodded once, already turning. "Come on." He walked out of the kitchen without looking back. Seungmin followed, the forgotten dinner ingredients left scattered across the cutting board.
They stepped into Jeongin's bedroom and the door clicked shut behind them. The room was dim, lit only by the small lamp on the desk. Jeongin sat on the edge of the bed and patted the space beside him. "Kneel between my legs."
Seungmin hesitated at the foot of the bed, fingers twisting the hem of his shirt. "Right now? Just like that?"
"Yes. You said you'd learn." Jeongin's tone stayed even, almost bored. "Take your time if you need it, but we're not leaving until you get this right."
Seungmin swallowed hard. He lowered himself slowly, knees meeting the floor between Jeongin's spread thighs. His hands rested on his own legs, unsure where to go. Jeongin reached down and unbuttoned his own pants, pushing them and his underwear down just enough to free his cock. It rested half hard against his stomach.
"Start with your tongue," Jeongin instructed, voice calm. "Don't just bob your head. Use the flat of your tongue along the underside first, then circle the head. Press and lick at the same time. Watch how I react."
Seungmin leaned in, breath shaky. He dragged his tongue from the base upward in one slow stripe, tasting warm skin. Jeongin hummed quietly in approval. Encouraged, Seungmin flattened his tongue more and licked again, slower, pressing firmer. He circled the head next, swirling the tip of his tongue around the ridge before flicking across the slit.
"Good," Jeongin said. "Now open your mouth wider and take the head in. Keep your tongue moving underneath while you suck. Don't rush."
Seungmin parted his lips and slid the head past them. His tongue stayed busy, stroking the sensitive underside in steady waves. He sucked gently at first, cheeks hollowing slightly, then increased the pressure when Jeongin's hand settled lightly on his hair.
"That's it, puppy," Jeongin murmured. "You're doing well already. Keep that tongue working."
The praise hit Seungmin like a spark. His shoulders relaxed a fraction and he leaned in further, taking more of Jeongin's cock into his mouth. He kept the tongue motion going. Long, firm licks along the shaft combined with quick circles whenever he reached the head. Saliva built quickly, making everything slicker. He swallowed around the length and felt Jeongin twitch against his tongue.
Jeongin's fingers threaded deeper into Seungmin's hair, not pushing, just holding. "Check in with me," he reminded. "Ask how it feels. Don't assume."
Seungmin pulled off with a wet sound, lips shiny. His voice came out rough. "Does... does this feel good? Am I doing it right?"
"Yes," Jeongin answered immediately. "Your tongue pressure is perfect. Keep going, puppy."
Seungmin's cheeks flushed deeper at the word. He dove back down, taking Jeongin deeper this time. His tongue pressed hard along the vein on the underside, dragging upward on every upward stroke of his mouth. He alternated between long, slow licks and quicker flicks at the head. Every few passes he paused to swirl his tongue around the crown, collecting the precum that had started to bead there.
Jeongin's breathing grew heavier. "You're learning fast. Use your hand too. Wrap your fingers around the base and stroke in time with your mouth. Twist a little on the upstroke."
Seungmin obeyed at once. His hand closed around the lower half of Jeongin's cock, stroking upward to meet his lips. He twisted his wrist slightly each time, matching the rhythm of his sucking. His tongue never stopped moving. That constant, wet pressure had Jeongin exhaling through his teeth.
"Fuck, just like that," Jeongin praised. "Good puppy. You're listening so well."
Seungmin took Jeongin deeper until the head nudged the back of his throat. He held there for a moment, swallowing around the length, then pulled back and repeated the motion. His tongue stayed flat and broad on the underside, licking firmly every time he descended. Saliva dripped down his chin and onto his hand, but he didn't stop.
Jeongin watched him closely. "Check in again."
Seungmin pulled off, breathing hard. Strings of spit connected his lips to Jeongin's cock. "Is this... is this better? Should I go faster or slower?"
"Slower right now," Jeongin said. "Build it up. You're doing great, puppy."
Seungmin nodded and went back down, this time moving with deliberate slowness. His tongue traced every ridge and vein, pressing and licking in long strokes. His hand kept stroking the base at the same measured pace. Every few seconds he glanced up through his lashes, silently asking for more feedback.
Jeongin gave it freely. "Perfect. Keep that pressure on the underside. You're making it feel really good."
Seungmin's eyes fluttered at the praise. He doubled down, sucking harder while his tongue worked in tight, wet circles around the head on every upstroke. His hand twisted and stroked in sync, creating constant stimulation. The room filled with the wet sounds of his mouth and Jeongin's quiet breaths.
After several minutes Jeongin spoke again. "Try taking me all the way. Relax your throat and let it slide in. Breathe through your nose."
Seungmin tried. He opened wider and pushed down until his nose brushed Jeongin's skin. His throat fluttered around the intrusion. He held for three seconds, tongue still licking what he could reach, then pulled back with a gasp. Spit ran down his chin in a thin line.
"Again," Jeongin said softly. "You're doing so well, puppy."
Seungmin went down once more, deeper this time. His throat accepted more of the length. He swallowed around it, the motion squeezing Jeongin tightly. His tongue pressed upward in firm strokes even while buried deep. When he pulled back he immediately went down again, establishing a rhythm of deep, wet sucks punctuated by constant tongue movement.
Jeongin's hand tightened in his hair. "Check in."
Seungmin pulled off, voice hoarse. "How does it feel now? Am I... am I pleasing you?"
"Yes," Jeongin answered. "Keep going exactly like that."
Seungmin returned to his task with renewed focus. He combined everything—deep throat strokes, twisting hand movements, and relentless tongue pressure. His mouth stayed slick and hot, sliding up and down with wet sounds. Every time Jeongin praised him he moaned softly around the cock in his mouth, the vibration adding another layer of sensation.
Jeongin's hips twitched once. "Close," he warned. "Keep that tongue moving, puppy."
Seungmin didn't stop. He kept the same steady rhythm, tongue licking firmly on every stroke while his hand twisted at the base. When Jeongin came he swallowed most of it, only a little escaping at the corner of his mouth. He stayed on his knees, licking Jeongin clean with slow, careful strokes of his tongue until the other man gently pulled him off.
Jeongin looked down at him, expression still calm. "You did really well, puppy"
Seungmin wiped his mouth with the back of his hand, breathing still uneven. The praise lingered in his chest, warm and heavy…
Seungmin stayed on his knees a moment longer, lips still shiny and slightly swollen. His breathing had not quite settled when he looked up at Jeongin with wide eyes. "Innie... what about when Changbin hyung is fucking me? How do I make sure he feels good then too?"
Jeongin studied him for a second, then stood and pulled his pants the rest of the way off. "Get on the bed. On your back. Legs spread."
Seungmin hesitated only a heartbeat before climbing up. He lay back against the pillows, knees bent and thighs parted. Jeongin climbed between them, already almost hard again. He reached for the small bottle of lube on the nightstand, he always kept it within arms reach just in case. He then slicked two fingers and pressed them against Seungmin's hole without warning.
Seungmin gasped at the sudden intrusion. "Ah!"
"Relax," Jeongin said evenly. "I'm going to show you how to take it so the other person stays interested the whole time."
He worked his fingers in deep, scissoring and curling until Seungmin's hips twitched. When he added a third finger Seungmin let out a shaky whimper, thighs trembling around Jeongin's wrist. Jeongin kept the pace steady, stretching him thoroughly while watching every reaction.
"When he's inside you," Jeongin instructed, "don't just lie there. Move with him. Roll your hips up to meet each thrust. Squeeze around him when he pulls back. That pressure keeps him engaged."
Seungmin nodded quickly, voice already thin. "O-okay... I'll try."
Jeongin withdrew his fingers and grabbed a condom. “Innie? Can you maybe do it raw? I-i mean I’ll probably learn better that way.” Jeongin thought about it for a second before putting the condom back. “If that is what you want, puppy.” Jeongin lined himself up against Seungmin’s rim before he pushed in slowly, the thick head stretching Seungmin open inch by inch. Seungmin's mouth fell open on a long, broken moan. "Hnnngh! Fuck!"
Once Jeongin was fully seated he stayed still, letting Seungmin adjust. "Check in with him," he reminded. "Ask if he likes how tight you feel."
Seungmin swallowed hard. "D-does it... does it feel good? Am I tight enough?"
"Yes," Jeongin answered. "Now start moving your hips."
Seungmin rolled upward experimentally. Jeongin responded with a slow thrust that dragged along his walls. The motion pulled another whimper from Seungmin's throat. "Ah…ah!"
Jeongin set a measured pace at first, each thrust deliberate. Seungmin tried to match him, lifting his hips to meet every downward stroke. His hands clutched at the sheets. Every time Jeongin bottomed out Seungmin let out a high, needy sound that only grew louder as the rhythm built.
"Harder," Seungmin gasped after a minute. "Please” he whined, “show me harder"
Jeongin obliged. He gripped Seungmin's thighs and drove in with more force, the bed creaking beneath them. Seungmin's moans turned into continuous, desperate whimpers. "Ah ah fuck—! Innie! It's so deep!"
Jeongin leaned over him, bracing on one arm while the other held Seungmin's leg wider. "Squeeze," he ordered. "Clench around me."
Seungmin obeyed, tightening his inner muscles on every withdrawal. The added pressure made Jeongin grunt. "Good puppy. Keep doing that."
The praise made Seungmin's cock twitch against his stomach. He clenched again on the next thrust, earning another low sound from Jeongin. His own noises grew wetter, more broken. "Nngh! Yes! Like that!"
Jeongin picked up speed, fucking him in hard, steady strokes that slapped skin against skin. Seungmin's head tipped back, throat working around constant moans. "Ah ah ah! Jeongin! Feels so good! Don't stop!"
The lesson blurred quickly. Jeongin stopped giving instructions and simply chased his own pleasure, pounding into Seungmin with enough force to rock the smaller body up the bed. Seungmin took every thrust with loud, shameless sounds, legs wrapped tight around Jeongin's waist. His hole fluttered and squeezed greedily around the thick cock driving into him.
"Puppy," Jeongin groaned, "you're taking it so well."
Seungmin whimpered at the words, eyes glassy. "Harder…please! Fuck me harder I need it!"
Jeongin slammed in deeper, angling to hit the spot that made Seungmin cry out sharply. "There! Right there! Ah ah—!"
Sweat slicked their skin. Jeongin's thrusts grew rougher, less controlled. Seungmin's moans filled the room, high and constant, mixing with the wet sound of Jeongin's cock sliding in and out. Every few strokes Seungmin would clench hard on purpose, trying to pull Jeongin deeper. The motion made Jeongin curse under his breath and fuck him even harder.
Seungmin's hands left the sheets to grab at Jeongin's shoulders. "Innie! I'm close!"
"Come for me," Jeongin told him. "Good puppy."
Seungmin came with a broken sob, cum streaking across his own stomach while his hole pulsed around Jeongin's cock. Jeongin kept thrusting through it, chasing his own release. A few hard strokes later he buried himself deep and came, filling Seungmin with hot pulses.
They stayed locked together, breathing hard. Jeongin finally pulled out slowly, watching the mess drip from Seungmin's stretched hole. Seungmin lay limp and trembling, small whimpers still escaping his throat.
Jeongin brushed damp hair from Seungmin's forehead. "You did well. Changbin is going to feel the difference."
Seungmin managed a shaky nod, voice hoarse. "Thank you... Jeonginnie."
