USU Ch 7

I was startled by Seo Gihyun’s sudden command. I wondered if this was how things typically began, but then again, it wasn’t like I was a kindergartener who needed a formal announcement to start.

Besides, since this was our first play after signing the contract, I didn’t want to ruin the mood right off the bat, so I nodded obediently. Leaving Seo Gihyun, who was leisurely smiling, behind, I headed toward the playroom filled with menacing SM tools. The door, which must usually be kept tightly shut, opened effortlessly since it hadn’t been locked earlier.

Though I’d been in this space with Seo Gihyun just moments ago, entering alone made it feel particularly oppressive. But it wasn’t just me—most people would likely feel the same. With one wall lined with tools that looked like torture devices, how could anyone not feel a chill?

Near the full-length mirror stood a chair designed to hold someone with their knees up and legs secured above. I’d noticed it earlier, but the starkness of it was striking. Still, since I’d committed to this, I decided to fully engage. Half-heartedness didn’t suit me.

Unsure where to put my clothes, I stripped off my shirt first, tossing it onto the sofa next to the cabinet filled with adult toys. As I reached for my belt buckle, a question floated up.

‘Do I take off my underwear too?’

He’d said to strip completely, so probably. Being fully naked felt a bit embarrassing… Especially since Seo Gihyun would likely walk in fully dressed.

Caught in indecision, I fumbled with the buckle when I heard the door open. A quiet presence stirred behind me.

“I’m pretty sure I told you to strip and kneel while waiting.”

His commanding, authoritative tone seemed to press down on me. Turning, I saw Seo Gihyun leaning casually against the doorframe, staring at me intently. It was unmistakably the demeanor of a “Master.” I stammered a response.

“Strip… completely, does that include underwear…?”

“What, you thought it didn’t?”

His cold, sarcastic tone sent a shiver down my spine. It was a sharpness I’d never heard from Seo Gihyun before, making my skin prickle. Oh, this is it—the real start of the play. The realization hit me vividly.

“Since it’s your first time, I’ll let it slide.”

“…”

“What are you doing? Get ready.”

His slightly altered demeanor, different from the earlier warmth, actually eased my embarrassment. His “Master” attitude made the reality of the play sink in, making it less awkward. If he’d just bluntly told me to strip, I might’ve hesitated.

I touched the buckle I’d been fiddling with. The clink of cold metal rang out, followed by the sound of my pants’ zipper sliding down. As I bent to remove them, I caught a glimpse of Seo Gihyun in the mirror. He was silently observing every move I made.

I slipped my fingers under the band of my dark navy drawers. I sensed Seo Gihyun moving slowly behind me. Thinking he was approaching, I tensed, but he headed toward the wall of tools. He scrutinized it thoughtfully, picking out items to use on me today as if shopping. I kept stealing glances while removing my underwear.

My fingertips trembled slightly—not from fear, but from recalling the sensation of being spanked by Seo Gihyun yesterday. His bare hand had hurt plenty, but now he held a paddle—the very one I’d earlier dismissed as looking like a spatula.

Next, Seo Gihyun moved to the cabinet. I swallowed dryly and knelt as instructed. My stomach churned with a noisy sensation, but it wasn’t unpleasant. It felt like discovering a side of myself I’d never known in my twenty-odd years. Did I enjoy submitting to someone? It made me reflect on my life anew.

‘If I’m honest, it’s less about enjoying submission and more about liking the tension of being dominated in a situation like this…’

A strange heat bloomed in my core, and I felt half-erect, unable to discern whether it was the thrilling pleasure or pain Seo Gihyun had given me.

A soft click sounded as the cabinet drawer closed. I looked up at Seo Gihyun. In his hands were a plastic paddle, a pink rotor, and something else that seemed part of a set.

What’s that? It looks like a remote control.

As I puzzled over it, Seo Gihyun approached and casually placed his foot between my knees, nudging them apart. My still-soft penis was fully exposed, and my face flushed.

“Ah…”

“Hands behind your back.”

I obediently crossed my wrists behind me at his impassive command. My vulnerable exposure kept making my face burn. Even so, thoughts swirled—how much more would the paddle hurt than a hand? Where would he hit? What was that remote-like thing?

I licked my dry lips slowly. Seo Gihyun’s gaze raked over me from bottom to top, lingering on my sparsely haired penis, flat abdomen, and already-swollen nipples despite no touch. His eyes felt like a tongue licking my body. Just being watched made me feel devoured, a dull heat blossoming in my lower belly. The room’s temperature hadn’t changed, but I felt hot.

Still looking down imperiously, Seo Gihyun touched my cheek. The slight contact felt hypersensitive. Overwhelmed by surging tension, I let out a small, “Hng.” He lifted my chin with his index finger, smiling faintly.

“Safe word. You remember it, right?”

His gaze held no trace of warmth. Seo Gihyun was now fully a sadist and dominant. I met his cold, sunken eyes, my toes curling stiffly.

I could no longer deny his words. He was right. I had a natural talent for this—or at least an interest. The merciless sensation of him harshly spanking my buttocks came to mind—the red, vivid handprints on my pale skin, the sharp, tingling pain, and the dull pleasure that followed.

My gaze drifted to the paddle in his hand. I swallowed dryly, my throat bobbing. The masochistic pleasure I was just beginning to understand slowly raised its head.

I nodded and answered meekly, “Yes, Master.”

It was a response signaling my full commitment to the play, not just for Seo Gihyun but for myself. His smile deepened, clearly pleased.

“We’ll start with the paddle today.”

Reflexively, I glanced at the paddle. Its wide surface, glossy black plastic, looked less threatening than a riding crop or cane.

Perhaps my thoughts showed on my face, as Seo Gihyun let out a deflating chuckle. He ordered softly, “Lie face-down on the sofa. Keep your hands behind you.”

I wanted to ask why, but the mood suggested that questioning the Master as a sub might not go over well, so I followed his instructions silently. It was a bit embarrassing to be fully exposed in front of a impeccably dressed Seo Gihyun.

I pressed my chest against the sofa, lifting my hips slightly. My privates were completely bared. Suddenly, something hard and cold touched my soft perineum.

I flinched, ruining my posture in shock.

“Hng…! W-what’s…”

Turning in panic, I saw Seo Gihyun’s stern expression as he sharply smacked my buttocks.

“Ugh!”

“Who said you could break position?”

“N-no, I mean, Master…”

I wanted to rub my stinging, red-marked buttocks, but since I’d been scolded for moving my hands earlier, I couldn’t. I rubbed my cheek against the sofa’s leather, half-turning my head.

“I-I was startled…”

“…”

“Something touched me…”

Explaining it wasn’t intentional softened Seo Gihyun’s expression slightly. He gently rubbed the buttocks he’d hit hard, leaning close over my back. His voice came near my ear.

“I really dislike things slipping out of my control, Gyeom.”

No surprise there—he’s a dominant. But that’s not it… I only looked because something startled me. Feeling wronged, my breathing quickened with frustration.

Thinking I was crying, Seo Gihyun pressed his chest closer to my back. I could faintly feel his heartbeat.

“It’s fine to look, but you need to follow orders, okay?”

“Mhm.”

His seemingly gentle tone had a firm core. Immersed in the coercive atmosphere, I nodded unconsciously. I’d been genuinely startled earlier, but with Seo Gihyun so close, I felt reassured. His body heat against mine was comforting.

Maybe this is why people do free hugs… I was lost in that silly thought when something touched me again from behind. Unlike earlier, perhaps because Seo Gihyun was close, I didn’t jump. But when the hard object on my perineum began to vibrate faintly, I startled again.

“W-what…”

“It’ll feel better if your body’s a bit warmed up before we start hitting.”

“Huh… what?”

I desperately wanted to turn and check, but pinned under Seo Gihyun, I could only flail my head uselessly.

“Let’s put this in first, then hit.”

His words brought the tool in his hand to mind—the pink, round device. Judging by its trembling, it was a rotor. I’d never used one, but I’d seen them on an adult toy site shortly after first sleeping with Seo Kijoon. Knowing it wasn’t his thing, I hadn’t looked again.

“Hngh, ugh…”

Fear crept in. It was my first time having a toy inserted below. The place that had only known Seo Kijoon’s cock now felt the touch of a cold, hard plastic object.

As I whimpered, Seo Gihyun’s sadist switch seemed to flip, and he chuckled lowly.

“Our Gyeom, you’re not a virgin, so why are you shaking so much? It’s cute.”

“I-I’ve never done this before…”

“Oh, first time with toy play?”

“Mhm.”

Despite my trembling, Seo Gihyun seemed to enjoy himself more, rubbing the lube-slicked rotor across my perineum, balls, and hole. When faint vibrations touched unexpected places, my body jerked as if electrified. The rotor’s movement made wet, squelching sounds from the lube.

“Haaah…”

“You seem to like it pretty well for a first time.”

“N-no, that’s not… ngh, ah, there…”

The trembling rotor pressed firmly against one swollen ball. It was entirely different from the light sensation that had teased my perineum and clenched folds.

When Seo Kijoon thrust inside, I’d often chased greater pleasure by gripping and shaking my own cock or kneading my balls. But now, the relentless, precise pleasure from a small, vibrating point made my vision flash. The one-sided stimulation felt especially intense.

As I gasped and shook my head wildly, Seo Gihyun kissed my nape. His tongue and lips, sucking my skin, were searing. All day, both he and Seo Kijoon had been obsessively touching that spot.

“Aahng, ah, haak…!”

“See, you like it.”

“Stop, there, it’s weird…”

Unable to continue, I pushed against the floor with my toes, thrashing. Even if it meant another spanking, I wanted to free my hands to stop him. But with him pinning me from behind, it was as good as being bound.

“Please, Seo Gihyun… no, Master. Just a moment, let me rest, ngh!”

Only when I begged with a near-sobbing voice did Seo Gihyun lift the rotor from my ball. My legs gave out from the overwhelming pleasure, trembling even as I leaned against the sofa.

“Up you go.”

Unfazed by my limp state, Seo Gihyun moved freely. He lifted his torso, which had been pressed against me, and slid his hand under my belly, still flush against the sofa. This time, he pressed the rotor against my cock.

“Hngh!”

A groan escaped me. The unexpected sensation nearly made me bite my tongue.

“Why do you keep saying stop? Look here, Gyeom. Your cock.”

“Ah, wait.”

“You’re so turned on, it’s this hard.”

Then it happened. The rotor’s vibration intensified. I faintly heard a button being pressed. Only then did I realize the square plastic in his hand earlier was a remote.

He rubbed the strongly vibrating rotor against my glans, tapping the shaft. It relentlessly targeted the indented tip of my swollen glans, as if piercing through. I writhed, panting. My posture had long since collapsed. Just keeping my knees on the floor was exhausting.

“There, like that… ah!”

My toes curled tightly. I no longer had the strength to push against the floor. The stimulation on my balls had been overwhelming enough, but now the intense rubbing near my urethra was unbearable.

“Ngh! Hah, ah!”

Unconsciously, high-pitched moans spilled out. Seo Gihyun kept stimulating my cock—rubbing the shaft, kneading the base. Either one alone would’ve driven me crazy, but both my urethra and cock being teased at once was maddening. I twisted my hips like a fish out of water, crying out. Fireworks seemed to explode in my head.

“I’m gonna come, ngh…!”

“Already? Hold it a bit longer.”

“No, I can’t… ah!”

I was definitely reaching climax faster than usual. But I’d been relentlessly teased by the rotor for a while now. Hold it? Are you kidding? He should be praising me for lasting this long.

My lower belly tightened, and my thighs tensed. I was on the verge of coming.

But then—

“Ah…?”

The buzzing vibration suddenly faded. On the brink of climax, I let out a dumbfounded sound.

“Why, hngh… why, all of a sudden…”

The guy who hadn’t listened when I was thrashing and begging him to stop had now pulled away completely. The rotor pressing my glans and the hand tapping my cock no longer touched me.

The torment was mine alone. Just a little more—a tiny bit—and I could’ve come. Panting, I twisted my torso. My legs gave out, and I collapsed onto the floor. My buttocks, sore from yesterday’s harsh spanking, throbbed, but my desperate need to come was stronger. I just wanted to jerk off and release.

Seo Gihyun merely smiled. The rotor, which had been vibrating strongly, was now off, likely via the remote. I glanced at the rotor that had tormented me, then at the calmly smiling Seo Gihyun. Without hesitation, I reached down.

But Seo Gihyun was faster. He swiftly grabbed my hand. As I tried to use my other hand, he caught that too. I writhed, resisting. Tears welled in my eyes.

“Why… why are you doing this! I want to come, let go!”

“What’s the point of calling me Master with your mouth?”

“What?”

My voice came out sharp. Right now, I was blind with need. My inner thighs trembled. My cock, denied release, throbbed painfully. My eyes burned.

“You should be begging your Master to let you come, not trying to touch yourself.”

He easily bound both my wrists with one hand, then slid his fingertips up my rigid cock. My body jolted.

I pleaded, nearly sobbing, “Let me go…!”

“Hm. More politely, Gyeom.”

This sadistic bastard. I was losing my mind, but his eyes sparkled with playful amusement. My cock, twitching on its own, leaked sticky precum down the shaft. Some drops fell to the floor as it jerked.

His grip was inescapable. My hips moved back and forth instinctively, desperate to come. Sniffling, I clung to him piteously.

“Please, Master. Okay?”

“Yes, Gyeom. What should I do for you?”

His voice was infuriatingly gentle, contrasting the brutal strength pinning my wrists. Do what, you pervert! I wanted to snap, but to escape the torment, I humbled myself further.

“I want to come. Please let me come.”

“You need to ask more prettily. Is that how you make a request?”

I couldn’t even grasp what “more prettily” meant.

My cock ached from being denied. The swollen glans kept leaking precum. So this is why they call him a sadist—he’s enjoying watching me cry in torment.

But what could I do? I was going crazy, but I couldn’t call out for Seo Kijoon here.

‘More prettily…’

My fevered mind raced. Seo Gihyun likely wanted a submissive who obeyed perfectly. My gaze fell on his hand gripping my wrists.

I rubbed my flushed cheek against the back of his hand. I licked it, even kissing it noisily. A tear rolled down my cheek. I eagerly licked and nuzzled his hand, rubbing my thighs together.

“Ngh, Master… please…”

“…”

Perhaps not expecting this, Seo Gihyun stared at me briefly. In my impatience, I shook my hips faster and began sucking his fingertips. Only then did a sigh-like breath escape his lips.

“Ha…”

“Master… hurry…”

I sucked his fingers as if they were his cock, lost in the act. Suddenly, my view shifted upward. Seo Gihyun lifted me, hips swaying on the floor, and tossed me onto the sofa.

“Ah!”

“Gyeom, you’re really…”

“Ahn, ngh! Ah, ah!”

His hand slipped between my legs, jerking my cock and rubbing my urethra with his thumb. I convulsed under the crashing waves of pleasure. My brain seemed to sizzle. I’d never felt anything like this before.

“Ah, there…! More! Harder! Ngh!”

“For Seo Kijoon to have had this all to himself?”

His voice sounded almost angry. I didn’t care—I was swept away, thrusting my hips wildly. Saliva I couldn’t swallow dribbled down my chin.

“Haaah! It’s too good…!”

“So shamelessly lewd.”

Seo Gihyun slapped my inner thigh. Meant to scold, it only heightened my pleasure. As the sharp sensation spread, my teetering body hit climax. From my glans, rubbed raw by his thumb, watery semen shot out. My lower belly spasmed. Held back so long, it didn’t release in one go but spurted over several waves.

“Hnngh…”

I arched my back slightly, savoring the afterglow. It lingered deeper than usual. When I couldn’t come, I’d hated Seo Gihyun, but now I thought being controlled like this wasn’t so bad sometimes.

Seo Gihyun gently stroked my back. I lifted my tear-soaked face to look at him. His deep gaze was nothing but sweet.

After floundering in the afterglow for a while, I finally slumped onto the sofa. Seo Gihyun, leaving me be, picked up the rotor and paddle from the floor. Oh, is it over for today…?

Just as my eyelids began to droop, he tapped my cheek with the paddle.

“Huh…?”

“You’re relaxing when we’re just getting started.”

What? No way… I’m exhausted. This isn’t the end?

Normally, I could handle another round of sex. But I’d been with the twins for two days straight. Just yesterday, I’d been spanked in this house, and without proper rest, I’d come here because of Seo Kijoon.

My tear-streaked lashes trembled. Ignoring me, Seo Gihyun stood and approached the cabinet full of adult toys. In his hand was a pair of leather cuffs. I flinched, scooting back. No way… he’s not using those now, is he?

“Why, hngh… what’s that?”

“Hm? What.”

His casual reply made me wonder, absurdly, if he wasn’t going to use the cuffs on me. Maybe he’d wear them himself…

But of course not. Smirking, he fastened them on my wrists. Too drained to resist properly, I let him handle me, sniffling as I asked, “Why these?”

Strictly speaking, it was better than earlier. When he’d pinned me, I couldn’t move my torso at all. The cuffs, linked by a thin chain, allowed more freedom than before.

As I stared dazedly at them, Seo Gihyun answered, “Because you keep trying to touch yourself.”

“I… I won’t touch.”

Still, fear was fear. Seo Gihyun was clearly planning to use the rotor and paddle to drive me to the edge again. The thought was dizzying and terrifying.

“I won’t touch, Master. Really… I promise.”

My shoulders trembled as I fixated on the cuffs. Seeming amused, Seo Gihyun asked in a slightly raised tone, “Safe word, you remember it?”

He gently stroked my damp cheek.

“You don’t have to be scared.”

“…”

“I’ll only make you feel good.”

He was right—he’d always made me feel good. He’d recognized that I might not be vanilla, that I could be a natural submissive. And the pleasure he gave was intense.

Swayed by temptation, I nodded slightly. It could feel even better than before, right? With the rotor… and paddle? How would he use them? As I stared at the tools, Seo Gihyun grinned and asked, “Already excited?”

“Huh?”

His question, as if reading my mind, startled me. The rotor in his hand began humming lowly again. The lube on it had dried while idle. He grabbed more, slathering it on, then pressed it to my collarbone. I flinched, giggling from the ticklishness.

“Ah… that tickles.”

As I laughed, Seo Gihyun chuckled softly too. Then he slid his hand down, rubbing my nipple.

“Still hard here.”

“Ngh, what…”

“Standing up, begging to be sucked.”

My ears burned at his words. His comment made me hyper-aware of my nipple, sensations rushing there. My body, limp moments ago, tensed again. My cock, spent from days of release, was half-hard again. I bit my lower lip, mumbling, “…I didn’t say that.”

“Hm?”

I’d spoken so softly that even with him pressed against my back, he didn’t catch it. Heat began pooling in my lower belly. Regardless of what I said, he kept rubbing the lube-slicked rotor on one nipple. The peaked bud flattened under it, then sprang back.

“What’d you say?”

“That I didn’t say to suck it, ngh…!”

His humiliating words sparked defiance. If only he’d treat me fully as a play partner like at the start—it’d be less embarrassing. But now, embracing me from behind like a lover, I felt like dying.

So the paddle… when’s he using it? My eyes searched the sofa for it when Seo Gihyun suddenly pushed me down and climbed on top.

“Huh…?”

Before I could react, he took the untouched nipple into his mouth, sucking hard. The abrupt pleasure made me throw my head back, crying out.

“Haaahng!”

“Still gonna deny it?”

“W-wait…”

“Look at this, mm.”

He hummed, mouth on my nipple, the low vibration resonating. Meanwhile, he kept rubbing the other with the rotor. Pleasure from both sides drew needy moans. My toes stiffened as he nibbled.

“Ngh, stop…”

“You can still say no?”

He pulled his licking tongue away, looking down at me. I glared at him with all my strength. Did he have to go this far? I just…

I wanted to deny it again, but I couldn’t. He was right. Seo Gihyun knew my body too well. As men, he naturally knew what felt good, but it wasn’t just that. Both he and Seo Kijoon were infuriatingly good at sex.

“Ngh!”

Then, noticing my distraction, the rotor nibbling my nipple and areola slid down my stomach. Its intensity increased, grazing my lower belly before reaching below. My half-hard cock stiffened fully, my hole twitching as if welcoming the rotor.

“You’re soaking wet down here. You really feel it, Gyeom.”

“What, what’s…”

What humiliating thing would he say now? Panting from pleasure, I looked down. My erect nipples and red, hard cock came into view. It twitched, dripping from the tip.

“Ah…”

A dumb gasp escaped. When did it get that hard? As I instinctively closed my legs and curled up, the round rotor pushed into my back hole.

“Ngh…?!”

The unannounced insertion made my body tense reflexively. Seo Gihyun slapped my buttocks, commanding firmly, “Relax.”

“Haa, wait…!”

Flailing my cuffed hands, I raised my knees as if to escape, only for another harsh slap to land on my hip. A loud smack echoed.

“Ah!”

“This’ll feel good once it’s in. Why keep saying no?”

I’d been mistaken. His relaxed demeanor wasn’t just his kind nature—it was because I’d obeyed well. Didn’t he say it himself? He hated things slipping from his control.

Look now—my struggling sharpened the air around us.

“Then… slowly. Okay?”

Cuffed, I had no real escape. I swallowed dryly. I was still safe. I had my ace—the safe word. If I used it, I could stop Seo Gihyun in a situation I truly hated.

Was having a rotor inserted that bad? No. I was scared, but also curious, like an eager student.

As I became compliant again, Seo Gihyun softened his sharp demeanor. He patted my buttocks and began inserting the rotor again. My hole parted, the long, round device sliding in. Compared to Seo Kijoon or Seo Gihyun’s size, it was tiny, but the sensation of something non-human entering was unsettling.

As my hole tightened, I felt the rotor settle fully inside. Relieved to have crossed that hurdle, I trembled.

“Haa…”

A tingling vibration hummed along my inner walls. Seeing my expression ease, Seo Gihyun chuckled.

“See, it’s fine.”

“Mhm.”

I nodded, twitching my hips. The faint vibration kept buzzing inside, but it wasn’t unbearable. Smirking, Seo Gihyun added a chilling remark.

“This is the smallest size. We’ll go bigger next time.”

“Why… why say that now?”

He’d said it to scare me on purpose. So infuriating. I glared at him, but he just shrugged. Then he picked up the paddle I’d forgotten about. It looked even more menacing now that I was about to be hit.

“Lower your waist and lift your hips.”

The blunt demand made my face flush. At the same time, my cock twitched hard. It was already dripping with precum. I squirmed, stealing glances at Seo Gihyun. Would he get mad if I asked him to touch me…? Then again, after coming once, I’d probably be too drained to continue the play properly.

‘Still… I want to come…’

Cautiously gauging his reaction, I asked, “Uh… you’re not going to touch the front?”

“…”

“I want to come…”

Seo Gihyun must know. Considering how hard I was, the fact that I hadn’t reached down to jerk myself off was already a feat of endurance. Sure, he’d cuffed me as a warning not to, but still.

Noticing my hesitance, Seo Gihyun didn’t seem displeased. He curved his lips into a pretty smile.

“Depends on how you do.”

“What kind of—”

“Let’s take a few hits first. Lie down and raise your hips.”

Feeling the buzzing vibration against my inner walls, I turned and lay face-down as he instructed. My lower half was fully exposed, but since all my nerves were focused on my rigid cock, I wasn’t too embarrassed.

Seo Gihyun patted my buttocks lightly, as if warming them up. Then he swung the paddle with force. A loud crack resounded as it struck my flesh.

“Ngh!”

I nearly lost my position. Trembling, I adjusted my posture. His words—depends on how you do—echoed in my mind. My stinging buttocks burned, and the rotor lodged inside vibrated intensely.

But I endured it all. I wanted to rub my smarting hips, but to come, I had to follow his orders.

“Good boy.”

Noticing my effort, Seo Gihyun smiled and praised me.

“What hurts more? My hand, or this?”

His sudden question made me tilt my head. Maybe because of body heat, being spanked by hand felt like it melded into my skin. Perhaps it was Seo Gihyun’s skill, but still.

The paddle, though… it covered a wider area, and instead of thrilling, it felt numbing. It was a different kind of pain, hard to articulate.

Besides, I’d only taken one hit—how could I distinguish much? As Seo Gihyun knew, I’d lived a vanilla life until now. Using toys during sex was only my second time. So I answered honestly, “I’m not… sure yet.”

“Hm.”

Glancing back at him, I mumbled, “Maybe if I take a few more hits, I’d know…”

At my response, a cold glint flashed in Seo Gihyun’s eyes. He drawled, “…Really?”

Without hesitation, he swung the paddle again.

“Hah!”

The paddle struck my buttocks repeatedly. Unlike handprints, neat red marks bloomed vividly across my skin.

“W-wait! Gently!”

“You beg for more and then say wait?”

Seo Gihyun let out a dry laugh, as if he couldn’t believe it. Beg? Me? Hold on, why’s he suddenly mad? Or… is he not mad?

‘He’s turned on? Why?’

What did I do wrong? I’d only answered obediently, but his sudden excitement threw me off. It seemed he was beyond reason now. He struck my buttocks several more times with the paddle.

“Ugh, ngh, ah!”

I braced my elbows on the floor to hold my position. My thighs trembled. The paddle alone hurt, but each strike made the rotor stimulate my insides more intensely. The tighter I clenched, the deeper it seemed to burrow, sparking a creeping fear. Unable to do anything, I clawed at the sofa’s leather, sobbing.

“Master, ah, Master…! Ngh, stop…!”

“You say stop, but why’s your hole twitching?”

His mocking tone made me jerk my head up. I couldn’t tell if he meant to shame me or not. Sobbing loudly, I shook my head frantically, my wet forehead rubbing against the leather.

“N-no, I didn’t, ngh!”

“Didn’t? If you got spanked in front of a mirror with your ass spread, it’d be obvious. Why lie?”

“Hngh, ah, gently…!”

The sound of relentless strikes continued. Unlike when he’d targeted one ball with the rotor, he alternated evenly between both cheeks. Heat surged across my buttocks. Marks must be vivid by now.

I’d underestimated the paddle. Not that I’d thought it weak, but I’d assumed it’d be similar to a hand. I was dead wrong.

Never once missing, Seo Gihyun struck my buttocks precisely until he finally stopped. Sniffling, I lifted my head from the sofa. I turned slightly to look back. My tear-soaked lashes made it hard to raise my eyelids. Through my blurry vision, I saw him—fully dressed, unlike my completely naked self. The contrast sent a throb through my lower belly.

“Hnngh…”

Panting, I swallowed hard. Seo Gihyun smiled softly, stroking my buttocks gently. It felt like permission to relax, so I eased my rigid posture.

Perhaps I’d read him right, as he helped me lie more comfortably. He turned me onto my back, licking the tears at my eyes. When his soft tongue touched my flushed cheek, I stammered in surprise, “I-It’s… salty.”

I rubbed the spot frantically. Seo Gihyun chuckled lowly.

“That’s what bothers you, Gyeom?”

“Not… bothers, but it startled me.”

My fumbling reply seemed cute to him, as he stroked my cheek. He tidied my sweat-dampened bangs, gazing at me warmly. He even uncuffed my wrists.

Where’s the dominant in this? The colder Seo Gihyun from the start seemed to fade with each moment of play.

But I didn’t mind. Why? Because he looked like Seo Kijoon?

“How was getting paddled?”

As I gazed up at him dreamily, he leaned over me. Pressing my erect nipple with his fingertip, he teased, “You’re still hard, so you must’ve liked it.”

By the way, he seemed to have completely forgotten about the rotor. I squirmed slightly, the vibrations still stimulating my insides.

“More than that… can you take this out now?”

I touched my lower belly where the rotor sat, the same spot that had bulged when Seo Gihyun fucked me two days ago. As I gingerly pressed, I almost felt the vibration on my skin.

Watching me, Seo Gihyun suddenly covered my hand with his, pressing down firmly. The vibration intensified.

“Hah! W-what are you doing?!”

“You’ve been spanked plenty—still not enough, Gyeom?”

His eyes, calm moments ago, gleamed with madness again. Why did he keep switching like this? I’d only asked to remove the rotor—how did that mean I wanted more?

But Seo Gihyun ignored my confusion. He caressed my inner thigh, then pressed between my legs. My hypersensitive cock, having come multiple times, jolted at the touch.

“No, ah, it’s enough!”

“Then let’s take my cum inside you now, Gyeom.”

“What?”

What did I just hear? Take what inside…? Stunned by the humiliating command, I furrowed my brow. He pressed harder on my half-erect cock.

“Knees up, legs spread.”

“Ngh, hey, wait…”

“Now.”

His urging voice dripped with excitement. His fevered eyes locked onto me. The rotor’s relentless buzzing inside was driving me insane, and now my cock was stirring again—maddening.

Despite my predicament, Seo Gihyun showed no sign of backing off. Instead, he unzipped his pants, pulling out his rigid cock and stroking it slowly.

And I was ridiculous too. Instead of panic, I swallowed dryly at the sight of his terrifyingly large cock. Remembering how it’d ravaged me two days ago and rubbed my thighs raw yesterday, my mouth went dry.

I was diligently learning the pleasure Seo Gihyun gave—through his play, his body. I’d always been quick to learn, and sex was no exception.

“Don’t make me say it twice, Gyeom.”

His gentle yet dangerous voice urged me again. He gazed at me with half-lidded eyes—dark, deep, beautiful.

If I screamed the safe word, too exhausted to continue, it’d all end. But if I obeyed… if I spread my legs for Seo Gihyun again, that beaded, magnificent cock would fill me completely.

Was I always this weak to temptation? Thinking so, I slowly parted my thighs. Embarrassed, I grumbled at him, “Uh… hurry and… take it out first.”

“Take what out?”

There he went again, teasing me while his cock throbbed with veins. Some sadist. I was seeing his true colors today.

“That… pink thing…”

“Hm?”

“…Forget it.”

Fine, I’d stick my own fingers in and dig it out. I turned sharply, but a faster hand pressed my chest, pinning me. I braced for a scolding for being cheeky during play, but surprisingly, he laughed easily.

“Alright, I’ll take it out.”

He spread my legs again. My hole, messy with precum and lube, gaped slightly.

“Hurry.”

“Yeah, sure.”

He answered halfheartedly to my urging. But instead of removing the rotor, he pressed his cockhead against my hole. After being teased by the rotor, it opened embarrassingly easily with a wet squelch. Expecting him to remove the rotor first, I jolted upright in shock.

Or tried to, if his cock hadn’t speared through me.

“Hah, ngh!”

A heavy jolt hit my hypersensitive walls. His beaded, menacing cock buried itself in one thrust. My lower belly felt tight, my skin slightly raised. As I looked down, Seo Gihyun smirked, amused, and pressed the spot firmly.

“Ahh, no, don’t, ah!”

“Wow, this feels… amazing.”

He laughed lowly, throat rumbling. A lazy curve graced his lips. Without thrusting, he pushed in fully, savoring the rotor’s vibration against his tip.

“Fuck, you crazy bastard… feels good? Ngh…”

I cursed instinctively. My insides were so full, clenching hard, and with the rotor buzzing, it was torture. Even breathing was a struggle.

“Yeah, it’s good.”

“I… hngh, hate it, you bastard. Get it out, ah…!”

Then it happened. As I panted my refusal, Seo Gihyun began moving his hips slowly. The rotor shifted with his cock, scraping every tender fold. His precum soaked my walls, making lewd squelches with each movement.

“You say no with your mouth, but your hole’s sucking me in.”

“That’s, ah, not…!”

“Not? Then what.”

Is he seriously asking? He’d know if he got fucked like this. Irritated, I sobbed, “Yours… it’s too, big! Ngh, fuck…”

“…”

Suddenly, his accelerating thrusts stopped. What now? I couldn’t read him at all. One minute he’s crazed with lust, the next he stops because I said it’s too big. Or… not because of that? Both Seo Kijoon and Seo Gihyun were impossible to figure out.

But then, he grabbed my flailing legs and hooked them around his waist.

“Wrap your legs around me.”

“Huh, what…?”

“So you can hold on.”

Hold on to what…? Before I could process, his cock, nearly pulled out, slammed back in.

“Ah!”

The sudden deep thrust threw my head back. His massive cock filled every inch, the rotor hitting my prostate precisely as his tip nudged it.

Each cry I let out made his thrusts fiercer. I wrapped my legs around his waist, clinging to his muscular torso like a lifeline. My insides boiled. My vision shook with his rough movements.

“W-wait, ngh, slow down, please…! Ah!”

The louder I wailed, the deeper he went. Semen, precum, and lube mixed inside, foaming at our junction with each withdrawal. Wet squelches sounded as his cock plunged in, pulled out, and slammed back, stretching me wide.

“I, haa, I’m gonna, come…!”

My hardened cock rubbed against our bellies with each shake. Both our lower abdomens were a mess, but I had no time to feel shame.

At my words, Seo Gihyun grinned. A bad feeling hit me. He lowered his hand, pressing my glans with his thumb. Tears poured out as the sensitive spot was rubbed. He growled, “Not yet.”

“Ngh, why, why… ah, Seo Gihyun, your hand!”

“Let’s… haa, come together, Gyeom.”

Each thrust of his beaded cock molded my hole to its shape. The faster he went, the louder the sticky mix of fluids squelched.

“Hngh, ugh, ah!”

Each prod at my prostate made my vision spark, but he wouldn’t let go. I clawed at his hand mindlessly, but he didn’t budge.

Then, as he pounded faster, Seo Gihyun suddenly buried himself deep and stopped.

“Urgh…!”

His broad back shuddered. At the same time, I hit climax. Our hips pressed together, lifting off the surface. My tear-soaked lashes trembled, scattering glimmers of light.

Having come thickly inside, Seo Gihyun rocked his hips, savoring the afterglow. My tender flesh was crushed. He pulled out his still-hot cock. After being pounded so long, my insides felt molded to him. My gaping hole leaked semen.

“Mmngh…”

Frowning slightly at the sensation, Seo Gihyun chuckled. He slid his fingers in, finally removing the rotor. Its persistent buzzing stopped.

Suddenly, he froze, staring at me as if noticing something.

“Wow, Gyeom, you came just from your ass?”

Now that he mentioned it… I’d definitely climaxed, but it didn’t feel like I’d ejaculated. Sure enough, my belly showed no trace of semen. Following my gaze, Seo Gihyun covered my stomach with his large hand. In my hypersensitive state, even that felt erotic.

“Hnngh, ugh…”

Watching me whimper, he licked his lips. His red tongue grazed his shapely mouth, impossibly sensual.

“Gyeom.”

My eyes widened.

“Crazy bastard…”

His cock, having just unloaded, was already hardening again. He kneaded it, slipping between my legs.

“Wait, I, just, came…”

“One more time.”

As if granting a grand favor, he said magnanimously, “Just sex this time, no play.”

Seo Gihyun curled his lips prettily, coaxing me. His handsome face, features sharp, softened with pleading eyes. That damn face—identical to Seo Kijoon’s—made refusal impossible. My heart, always off track, beat only for Seo Kijoon.

I bit my lower lip. My emotions surged like waves. A faint, barely audible reply slipped out.

“Then… gently, ngh…”

With no choice, I lay beneath him again, trembling and crying as if it were all fated.
