Vials of medicine and IV fluids rattled behind you, glass clinking faintly from the force as Nanami pinned you against the cold metal structure.
One of his muscular arms anchored above your head, caging you in. The other clenched into a fist by his side, veins straining with barely-contained control.
In the quiet, dimly lit supply closet, your breathing filled the silence, thick with tension, the air heavy with the sharp, sterile scent of disinfectant.
“You can’t act like you own me after fucking me once, Kento,” you spat.
His jaw clenched at your words, brows drawing together as his gaze darkened. “It’s sir for you.”
He tipped your chin up with a finger, leaning close, breath hot against your face. “Don’t act like you haven’t been making a fool out of me all day, brat.”
“Getting all touchy and squirmy ’round Dr. Higuruma?”
“You filthy whore. Aren’t you afraid I’ll fire you?” he growled.
You sneered, “Oh, please.” A mischievous glint danced in your eyes as you smirked. “And. So. What. If. I. Did. Sir~” You jabbed a finger into his chest at every word, each syllable dripping with teasing intent.
You sure damn did.
You threw on an extra-mini skirt today, only about six inches long or so, knowing exactly what you were doing. HR could try to file a report all they wanted but no one would touch you. No one dares mess with Nanami’s intern, and everyone knows it.
No one touches his things. Nanami was a strict man — harsh, stern, and polished. He spoke with no filter and was ruthless. Hard to impress, he tossed interns out faster than anyone else dared. No one was ever good enough for him. Everything set him off.
Till you came along.
You had him wrapped around your finger. He couldn’t resist you — your smirk, your teases, your body.
You made him feel things no one else could. You had him twitching, making noises he’d never dare let anyone else hear. You pleased him in ways others couldn’t, under the table, draped over his lap while he drove, anywhere you wanted.
You had him folded, undone, and you loved every second of it.
And so you decided to play a little game… to see just how far you could push him before he snapped.
You spent the whole day dodging Nanami on purpose, letting every glance, every word, every smile go straight to the new doctor in cardiology, Dr. Higuruma Hiromi.
As the coffee machine hummed softly in the break room, you let your pen slip, bending just so, and gave the new doctor a fleeting glimpse of your baby pink, laced panties, the tiny ribbon at the back scandalously visible.
You picked up the pen and sauntered toward the flustered man, slyly unbuttoning your blouse one button at a time as you spoke.
“Say, Hiromi…”
Pop.
“I’ve heard you’re a cardiologist…”
Pop.
“Think you can take a closer look at my heart?
Pop.
Your cleavage fell into his line of sight, daring him, while your hands reached for his, guiding it to the curve of your breast.
The door swung open with a small creak. The overworked blond man paused at the threshold, stiffening at the scene before him.
He crushed the paper cup in his fist with a sharp crunch, sending drops of leftover coffee splattering across his white coat, leaving a few dark blotches on the pristine fabric.
With his gravelly, low voice, he spoke.
“I need to have a quick chat.” His brows furrowed at the sight of you two, Higuruma’s reddened face practically buried between your chest. “With my intern.”
Now, in the cramped room, Nanami hissed. “Then you need to be taught a lesson, slut. That you belong to me and nobody else.”
“Oh? And how so?” you taunted, hands on your hips, hiding your excitement under a mocking tone.
Nanami shrugged off his jacket and dropped it onto a neat pile beside his polished leather shoes, his shirt creasing slightly with the movement.
He gripped your shoulders firmly, pressing you down just enough to make your legs buckle under the weight.
“On your knees. Now.”
The cold hospital tiles bit into your knees, a sharp contrast to the heat pooling between you.
Nanami unbuckled just enough to bare his cock, heavy and rigid, his waistband clinging on to his well-defined hips.
He grasped your face, thumb and fingers pressing into either side, shaping your lips into a soft, parted “O” and tilted your head up, forcing your eyes to meet his.
Without warning, he thrust forward, your breath hitching as he filled your mouth, the sudden intrusion drawing a choked gurgle from your throat.
His taste, faintly salty, lingered on your tongue as he drew back, only to thrust forward again, deeper, more deliberate this time.
“Needy little slut. Take all of me in,” he grunted. Your mouth, unable to keep up, let saliva pool and spill over, leaving a wet trail on the vinyl flooring beneath you.
He drew himself up, tapping the head of his cock against your glistening lips with a mocking plop.
“You belong to me. Got it? This pretty mouth… mine,” he snarled, teeth clenched.
When you didn’t respond, Nanami bundled your hair into his fist, tugging it back firmly, forcing his pulsating cock back into your throat again, fucking it relentlessly — fast and unforgiving.
Your scalp burned from the pull, tears welling in your eyes as you gasped for air, nostrils flaring with each ragged inhale.
Instinctively, your hands latched onto his hips, fists curling in whatever fabric you could get ahold of, a silent plea for him to stop.
He retracted, a slick thread connecting his tip to your quivering lips. “Answer when you’re being spoken to, filthy girl,” he demanded, his piercing stare sharp. “Got it?”
“Y-yes.”
“Speak up.”
“Yes… sir.”
“Good,” Nanami purred, pressing his cock on your face, stroking firmly along your cheek. “That’s more like it.”
Beneath your panties, you felt yourself slicken, aroused at every degrading word Nanami spat.
“Bend over,” he commanded, gesturing at the stacked boxes tucked away in the corner.
“Don’t make me tell you twice.”
Legs trembling and knee raw from kneeling, you collapsed onto the stacked boxes, skirt riding up your thighs with each shift, exposing your taut panties to his devouring eyes.
“Fuck!” he snapped, jaw tight. “I’m so pissed that some cardiologist saw this before me.” With one rough motion, he stripped your panties, massive hands gripping your hips and spreading you open for him.
“Pathetic bitch… want some other man’s eyes on you? Not happenin’.” He growled, the metal clasp of his belt clinking softly as he loosened it, letting the leather slide free and his slacks drop to the floor.
He traced a finger along your folds, slick practically dripping from you as he did. “Soakin’ wet already? Wonder if it’s me… or that fuckin’ heart doctor.” Veins popped in his neck, body tense with anger and possessiveness.
You gulped at his sharp, furious tone — he’d never snapped like this before and frankly — it turned you on like crazy. With a sly grin, you swayed your ass at him teasingly, only to earn a hard smack that made you flinch and shiver all at once.
“Don’t you dare move.”
“Tell ya what, you can look at whoever you want, but this body is mine, and I’m making your pussy remember that.” He snarled, pressing his body flush against yours as he thrusts sharply.
All you could manage was a soft “hmph” as your cheeks pressed against the boxes, feeling him so hard against you that you swore your cunt was being molded perfectly to his cock.
His massive hand, hot on your skin, clamped around your neck as you balanced on your hands, head thrown back, fucking into you harder and harder, every thrust claiming you completely. “So fuckin’ tight ‘round my cock. What a greedy whore,” he grunted, gripping tighter.
Skin-slapping noises echoed off the walls, mixing with your desperate pants. Your orgasm teetered on the edge, hips snapping back frantically, every nerve screaming for release. Then came the final straw:
“Remember… you’re my intern, my slut, only mine.” Nanami ground out the words, hips bucking against you as his own release drew near.
Your hand snaked between your thighs, desperate to stroke your clit for a faster release — only to be slapped away with a sharp smack.
“No.” Nanami barked as he flipped you onto your back effortlessly, pressing you flat against the cardboard surface beneath you. “You don’t get to cum.”
He pounded into you, each thrust staking his claim possessively, sliding out slowly before letting his cum spill across your face, dense and viscous.
It smeared across your eyes, clouding your vision, slicking your cheeks and lips. Some of it trickled into your mouth — hot, salty, and musky, leaving you tasting nothing but him.
“Hmm…” he mocked, leaning closer, a dangerous smile tugging at his lips. “Bad girls like you get punished, not rewarded.”
