Jimin's heart was beating at an astronomical pace. She could barely contain her anticipation as she watched the rising number of floors while in the elevator. Minjeong lived in an impressive complex in the heart of the city which lay no more than 30 minutes from campus.

"Breath, Jimin." Minjeong wrapped an arm around Jimin's waist, drawing tantalizing circles right under her chest. Jimin could feel the professor through her dress, causing her breath to hitch.

Jimin had no idea what the woman had planned. The naivety only excited her further.

Finally, the elevator came to a stop on the 22nd floor and Minjeong guided Jimin out. Her arm still around the student's waist, she followed Minjeong towards her unit located towards the left of the elevator. The professor unlocked the door to her duplex loft that had Jimin's jaw almost drop to the ground.

The place was beautiful in its own simple way. Nothing was over the top or excessively luxurious. The entire loft relied mostly on dark wood and sleek steel accents for an overall simplistic architecture.

Taking a few steps in, Jimin took in the furnishing that managed to feel homey despite its more minimalist nature, suiting Minjeong's taste and personality. Her eyes trailed up the smooth, wooden hanging staircase that led up to the lofted second floor which appeared to house multiple bedrooms.

Jimin heard the door to the apartment close behind her. Minjeong made her way around Jimin, placing her hands on Jimin shoulders as she studied the student gaze intently.

Minjeong's eyes were immediately much darker than Jimin had ever seen them before.

They were more carnal, lustful— Jimin felt naked under her professor predatory gaze.

"What are you thinking, Jimin?" Minjeong asked in a low voice.

Jimin paused. She looked at Minjeong, took in her surroundings, and let the situation sink in. "I'm wondering how much you can show me in one night." Jimin's response was barely a whisper.

Minjeong's eyes lit up at Jimin's answer, but not in her usual charming way.

Jimin saw something much more sinister behind the beautiful, hazel eyes that had captivated her mind the first day the student stepped into her class.

"Do you want me to fuck you?" Minjeong asked.

"Yes, please."

"Restrain you?"

"Yes..."

"Hurt you?"

"Please."

Jimin was willing to get on her knees and beg at this point.

Minjeong's breathing became more ragged and unsteady as she imagined Jimin at her mercy, bound, gagged— tears and mascara staining her face— In her control.

"Let's discuss protection," Minjeong abruptly inserted, shifting the topic before her own restraint cracked and she dragged Jimin to a certain locked bedroom.

"I'm on the pill." Jimin was diligent about her contraceptive for the past several years.

"I'm clean. I have medical documentation in my office, if you want me to grab it," Minjeong offered.

"I trust you."

Trust. It was a value Minjeong held above love.

The professor replied. "I know you're clean, too. I checked your college medical records."

"That sounds illegal."

Minjeong raised an eyebrow. "Oh, so we're following rules now?"

The young student pursed her lips, concealing a smile at Minjeong's humorous tone. Jimin continued the playful banter. "If you give me anything, I'll report you."

In a split second, Minjeong's hand was wrapped around Jimin's neck as she pulled Jimin closer. With her lips grazing the student ears, her erection hardened at the sound of Jimin restricted gasp.

"The minute you enter through my doors, you will only speak when I ask. One more disrespectful comment and I won't let you come once tonight."

Jimin didn't dare respond with anything other than— "Yes, Miss."

Minjeong loosened her grip, but not completely. Just enough to hear Jimin slightly struggle to reach air.

"What's your safeword?" Minjeong asked.

"Vanilla."

And with that, Minjeong hauled Jimin over her shoulder with her arm, holding Jimin in place. Jimin squealed, granting her a harsh slap to her ass.

"Quiet." Minjeong could've led Jimin up the stairs to their final destination herself, but her impatience got the best of her.

Jimin felt Minjeong's palm on her ass again, but this time she caressed and massaged the area.

Minjeong felt herself close her eyes for a brief second, listening to Jimin's beautiful and feminine moans. She savored them. Because she knew those same moans would turn into screams later that night.

Finally having reached the second level, Minjeong put Jimin down before an otherwise ordinary-looking door - no different than the adjoining ones nearby.

Except this one had a lock and keyhole.

Minjeong grabbed her set of keys from her pocket, singling out a specific bronze piece. She opened the door as Jimin followed her inside.

The room was bathed in a warm light as the couple entered the forbidden area. It wasn't too harsh, just dim and soft enough to highlight every entity in the room and sensualize the atmosphere. Jimin was first struck by the calming scent of wood and amber notes, which immediately quelled any anxiousness that had built up within her.

She felt every muscle in her body relax.

The room wasn't too large - it was smaller and intimate. The dark, mahogany flooring matched the wooden beams along the walls and ceiling, along with the frame of the grand four-poster bed centered alongside the back wall. The space appeared completely innocent at first until Jimin's eyes adjusted to the low lighting, and details began to show themselves.

She soon noticed that the side walls were discretely adorned with multiple built-in cabinets and drawers.

Jimin couldn't help but admire the beautiful architecture of it all. It perfectly reflected the professor - a gorgeous and scholarly academic with a labyrinth of hidden desires.

Jimin couldn't help herself. "Miss, may I open one?"

Minjeong simply nodded, her arms crossed. Jimin pulled one of the many ornate handles, practically holding her breath.

The inside, along with the back of the door, was adorned with ropes, restraints, leather shackles, and metal cuffs.

Unable to fight her curiosity, Jimin opened another.

There she found floggers, belts, crops, and canes in a variety of materials and textures. It was everything the young student had imagined and more.

The professor studied Jimin with hesitance as she took in the sight. Minjeong had gone into this night knowing she could react with horror and disgust. After all, this lifestyle wasn't for everyone. Those who think it's for them often run at first sight.

Except not for Jimin.

Minjeong almost found it breathtaking.

She was completely and utterly calm. At peace, even.

"Keep them open," Minjeong ordered. She guided Jimin to the center of the room right before the foot of the grand bed. Still eyeing the display on the walls, Minjeong tilted Jimin's head so her gaze met hers.

The fear Minjeong expected to see in her eyes was filled with lust instead.

"When you enter this room, Jimin, you're agreeing to submit to me. Completely. I will do as I please. You will do as I say. Understood?"

"Yes, Miss." It was all Jimin could say. She knew that anything Minjeong had planned for her, she wanted.

Minjeong circled around Jimin, her leisurely pace only edging her on further. She just wanted to be shackled and fucked.

And Minjeong knew that. Hence why the professor took her time.

Minjeong slowly unzipped Jimin's dress till it came to a stop at the hilt. She slipped the sleeves off and let the flowy material fall gracefully to the floor. Jimin's first instinct was to step out of the dress and discard it, but she quickly stopped herself. She knew she had to wait for her dominant's instruction.

Minjeong was so pleased with her effort.

The professor lightly tapped on the side of Jimin's thigh, signaling her to remove herself completely from the dress. Jimin stepped out and kicked it to the side. Next, Minjeong unhooked Jimin's black lace bra and slid it off her smooth arms until it fell to the floor.

Lastly, she motioned towards Jimin's shoes and she stumbled out of her heels until she was barefoot. Minjeong kicked the rest of the discarded clothing to the side, taking a few steps behind Jimin to admire the view.

And a view it was. Her curves were soft and glistened in the warm light, her honey skin smooth and pristine... a perfect canvas for what Minjeong had planned in her mind.

Minjeong traced along Jimin's thong, the contact sending goosebumps running along her skin. "Bend over and take them off - slowly."

With unsteady hands, Jimin hooked her thumbs along the sides of the lace material. She bent over, exposing herself to Minjeong - just as the professor wanted. She slowly pulled them down, as sensually as she could.

Minjeong's hand gripped itself into a hard fist, a vein in her forehead now visible. She held herself back from sheathing herself and thrusting into her with no warning, using the student until she felt satisfied.

Finally, Jimin straightened her back and tossed the flimsy material aside. Her eyes met Minjeong's as she stood in front of her once again.

"Kneel."

Jimin's knees hit the wooden floor before Minjeong finished the word. It felt so right amidst the wrong - her naked body kneeling before the woman whom she was giving all her trust to for the night.

This one night.

"Don't move."

Minjeong's shoes echoed against the floor as she moved from Jimin's field of sight. She could only look downward, watching Jimin's chest rise and fall with her measured breathing.

Minjeong grabbed what she needed from the open cabinets. With a thud, Minjeong dropped what she had brought before Jimin's eyes - which immediately lit up.

It was a set of jet black rope.

Jimin heard the material of Minjeong's expensive blazer shrug off her shoulder.

She immediately looked up, wanting to witness the beauty that would be this woman undressing. She's already hot and domineering stature was only accentuated from Jimin's point of view below her, with her crisp black dress pants complimenting her long legs.

Jimin could faintly see the ripples of her muscles under her dark dress shirt, which she quickly folded the sleeves of to expose her equally toned forearms. The woman had the proportions of a Greek God statue.

Jimin's mouth was practically watering. And Minjeong noticed.

"Eyes down." Minjeong's order cut through the tension, just as she began undoing the buttons of her dress shirt. Jimin begrudgingly returned her eyes to the floor.

Jimin could feel Minjeong's intense gaze upon her from above, despite only being able to see the professor shoes in her vision as she continued to look down. It turned on Jimin more than she wanted to admit. To be kneeling before Minjeong - having her look down at her like a queen does to her mistress.

For Minjeong, seeing the forbidden act of her student submitting before her was poison to her blood. It was a toxin she was going to take for just this one night.

"Who owns you?"

Jimin didn't miss a beat. "You, Miss."

"What's your purpose in this room?"

"To be used. By you and only you, Miss."

"Hold the rope and stand up," Minjeong ordered. She held out her hand and Jimin handed the rope to her, standing straight up at Minjeong's command.

Minjeong's undone tie lay lazily over her neck and the first several buttons on her shirt were open, exposing her breast.

Long gone was the charming professor Jimin saw in class and amongst her academic peers. This woman was heaven, hell, and everything in between.

"I'm going to ask you one more time Jimin," Minjeong's voice was smooth and dark like velvet. "Is this what you want?"

Jimin didn't hesitate for a second before responding.

"Yes, Miss."

—

Jimin closed her eyes for a brief moment. When she opened them, looking back at Minjeong was an intoxicating mix of curiosity and lust - as dark as an eclipsed night sky.

Minjeong's sinful eyes devoured Jimin's every thought. She felt naked not only with her bare and exposed body but in her mind as well.

Jimin had submitted both parts of her.

The woman before Jimin was unrecognizable.

Minjeong's previously styled waves were now disheveled, one lone strand falling out of place to frame her hardened expression. Her posture was relaxed and she seemed at ease, embodying her dominance and command.

This was the stability and strength Jimin craved in her life.

Minjeong didn't waste another second. She reached up, pulling a rig down from the ceiling above Jimin. The sound of the apparatus made Jimin immediately flinch, but she couldn't get far.

Minjeong grabbed Jimin's wrists and lifted them above her. She wore the black rope she had chosen through her wrists, binding them together. Minjeong pulled them taught, causing the student to whimper softly at the fibers rubbing against the thin skin. Minjeong paid no attention. She was moving too fast for Jimin to even comprehend. She took the remaining cord of rope and expertly tied it to the rig above Jimin.

Minjeong then grabbed Jimin's tied wrists and tugged hard, testing her knot skills and also displaying to Jimin what was inevitable.

She was completely bound standing upright - at Minjeong's absolute mercy.

Just as the professor wanted.

With Jimin's full attention still on the professor,  Minjeong began undoing her belt. The only sound in the still room was the metal buckle being unclasped and the leather being pulled in one deft movement. Jimin could feel the slickness between her thighs intensify.

"Let's do some math, although I'm sure you have another professor for that," Minjeong slowly spoke, circling so she was behind Jimin.

With Minjeong out of her vision, Jimin felt a sense of foreboding build-up. She couldn't anticipate anything Minjeong had planned.

Minjeong continued, aroused as Jimin's tensed state caused her to flinch at his every movement.

"First, you insinuated I was jealous of your friend. Then, you questioned my competence with other women... that's 5 lashes each. You spoke back to me so I added another 5. You forgot to address me as 'Miss' on numerous occasions... maybe I'll double it to 30..."

Jimin immediately pulled against her restraints in protest of the arbitrary additions. Where the fuck was she getting these numbers?

She quickly regretted that move.

Minjeong grabbed Jimin by her hair, yanking it back hard enough to make Jimin cry out. "Do you have an objection?"

"No, Miss," Jimin whimpered out.

Minjeong tugged at Jimin's hair again so that her mouth was against Jimin's ear. "In this room, Jimin, you're nothing more than a slut for me to use for my pleasure. Get that through your head."

Minjeong released Jimin's head, letting it fall forward. The professor continued his recount of Jimin's misbehaviors. "Did I mention you threatened to report me? What do you think I should do about that, Jimin?"

Jimin responded through gritted teeth. "Double it, Miss." She feigned contempt, but in reality, she wanted more.

"Good answer, darling." Minjeong's consoling words and tone melted Jimin's thoughts.

"You're going to count every stroke until thirty. Then, you're going to thank me. Lose count and I'll make you sleep on the floor tonight."

Jimin remained silent as she felt the cold leather of Minjeong's folded belt graze her tingling skin. Jimin felt like holding her breath, her nails digging into her palms as she tensed her hands into fists.

The first lash came down with a crack on Jimin's virgin, unbroken skin. She immediately cried out in clouded lust, a fire now burning deliciously across her ass. The student let the rope dig into her wrists in an attempt to deviate from her burning nerves.

Minjeong didn't go easy. The following successive strokes hit against Jimin's bottom quickly and with no remorse. The sound of her strained gasps and the leather of the belt against her damp skin pushed Minjeong's dark arousal to an even darker place.

The pain was Jimin's twisted pleasure. The stinging feeling of the leather snapping against her skin and the burning sensation following brought searing clarity to Jimin's mind. She could only let moans and breathy mumblings escape her lips.

Jimin got through half the punishment with indulgence. "Fifteen, Miss!"

At this point Jimin began to become restless, attempting to tense her muscles and pull on her restraints in response to the continuous onslaught.

Minjeong caught on, grabbing Jimin by the throat to pull her head back. "Stay still or I'll add more."

Jimin let out a humiliating moan. It was music to Minjeong's ears. Each successive lash began scorching the skin in the same area repeatedly. The feeling was so euphoric Jimin hadn't considered using her safeword once.

Minjeong could sense the strain she was putting on Jimin's petite frame. She was new to this after all. Between lashes, she would come up behind Jimin and massage the area to soothe the inflicted skin.

Jimin's cries and moans were becoming louder at each stroke, her self-restraint collapsing.

"Shhh—" Minjeong massaged Jimin's ass and thighs, assuaging the muscle. "You look beautiful like this, Jimin."

"Mmm, Miss." Jimin's thoughts were incoherent and jumbled. She couldn't help but sigh at the feeling of Minjeong behind her and the professor's breath on her sensitive neck. Jimin loved how Minjeong interchanged between her derogatory, chauvinist side and her reassuring one.

"Now, be a good girl and take the rest of your punishment," Minjeong ordered in a soft tone.

And Jimin did.

After Jimin cried out her final number, Minjeong tossed the belt onto the bed. She made her way in front of Jimin and wasted no time.

Minjeong inserted two fingers into Jimin's drenched entrance and groped her exposed breasts with the other hand, Jimin throwing her head back with a groan in response to the contact.

"Do you feel how fucking wet you are, darling?" Minjeong brought the same hand up to Jimin's mouth. "Taste it."

Jimin loved the degrading yet sensual act. She took in Minjeong, sucking and licking her arousal clean off her fingers.

Minjeong felt the feeling faintly mimic itself on her painfully erect shaft. She returned her hand back under Jimin, now circling over her tender clit. If it wasn't for the rope holding her up, Jimin's knees would've completely given out.

Minjeong worked her quickly and expertly. It didn't take long for Jimin to reach the edge.

"Beg and I'll let you come," Minjeong ordered, not stopping her pace. Minjeong could feel Jimin just begin to tense up as her breathing became more erratic and irregular.

"Please, Miss." Jimin couldn't bring herself to say anything else. Her mind and thoughts felt completely unhinged.

"More."

"Please!" Jimin cried out, contorting her body away from Minjeong to the best of her ability to stop herself from coming. "Please, please, please let me come. You can do whatever you want to me. Please, I can't hold it - fuck."

The second the command left Jimin's mouth, Minjeong unraveled. Minjeong's relentless pace only sent waves after waves of pleasure, leaving Jimin out of breath and in a haze.

With Jimin reaching her limit, Minjeong stopped. "Now, what do you say?"

Jimin couldn't help but smile. "Thank you, Miss."

Seeing the corners of Jimin's mouth tug upwards every so slightly gave Minjeong another idea.

"Show me how thankful you are." Minjeong grabbed a pair of rope cutters, freeing Jimin before tossing the object aside as it clattered against the wooden floor. The black rope tumbled down, leaving Jimin's wrist unbound and sore. Without the restraints, her limbs felt loose and numb.

It wouldn't matter, as Minjeong quickly pushed Jimin to her knees before her.

Jimin's excitement was at a high as she realized Minjeong's method of gratitude. She quickly freed herself, feeling an instant wave of relief at the lack of constriction. She immediately moved her mouth forward but felt a fistful of her hair pull her back with searing pain in her scalp.

"Manners," Minjeong spat out.

Jimin thought for a moment. "Please put my mouth to better use, Miss."

Minjeong couldn't help but smile at her recollection of her earlier words. That was the difference with Jimin. She was smart, witty, playful... all while on her knees.

Minjeong didn't want to let her go.

Minjeong channeled all her sexual frustration by thrusting into Jimin's throat with no warning, grabbing the sides of her head with crushing force. Minjeong immediately groaned at the feeling of her warm mouth around her.

She attempted to push in further but was met with resistance as Jimin had tensed up her throat and was aggressively pulling back by pushing against Minjeong's thighs.

Minjeong pulled out, Jimin immediately coughing and gagging at the intrusion.

"Looks like I have a lot to teach you outside of class, Miss Yu," Minjeong noted, her breathing ragged.

Jimin could only remain to kneel, still clearing her throat from the incursion. She felt bad.

"I'm sorry, Miss."

Minjeong's eyes softened as she tilted Jimin's head up to meet her gaze. "I'm going to push your limits, Jimin. Snap three times whenever you can't say your safeword, okay?"

The second Jimin finished nodding her head, Minjeong pried open her jaw and shoved her cock in her mouth again. This time she held Jimin's head in a way that gave her more leeway to move and let her brace herself against her thighs, holding herself back from fucking her face.

"Open your mouth, don't tense your jaw... relax the back of your throat, darling... tilt your head slightly up... that's it, Jimin."

Minjeong's soothing and encouraging instructions instantly mended any sorrow Jimin felt earlier.

She felt herself ease into the act.

Minjeong gathered Jimin's hair behind her, keep it out of her face. Jimin's mascara had begun running in streaks down her cheeks, like paint on canvas. Minjeong moved further down Jimin's throat, moving in and out slowly.

She let out an exasperated groan, only fueling Jimin further. She wanted to please her professor.

"Jimin— relax, baby - fuck." Minjeong almost doubled over as Jimin pushed her mouth further down her shaft. Minjeong took it as a sign, fisting Jimin's hair and taking full control.

Pushing her length against the inside of Jimin's cheek, Minjeong pulled out with a pop. Saliva and spit smeared both the head of her cock and Jimin's lips.

Jimin started to become restless as an ache began growing between her legs, begging for stimulation. Jimin only managed to get a few words out.

"Please, Miss—"

Minjeong quickly shut down any hope Jimin had. "Keep moving and I'll tie you down and fuck your mouth. Take it all. I don't care if you start to choke."

Jimin whimper came out as a needy whine as Minjeong filled her mouth once again. But she obliged. Minjeong pleasure was hers as well. Minjeong's movements became ragged and jerky as she chased her own release, leaving Jimin starved and untouched.

"Swallow it all, Jimin. I don't want a drop on the floor."

Jimin did exactly as her dominant asked. With Minjeong's hand gripping her hair with vigor, Jimin's felt a warm substance coat the back of her throat. Jimin felt just as proud of herself as Minjeong was for her.

Her moment of satisfaction was short-lived, as Minjeong pulled Jimin up by the back of her neck onto her feet. Minjeong gripped Jimin's jaw, forcing the student eyes to meet her.

"Remind me what you told me right before I let you come, darling."

Jimin shuddered at Minjeong's dangerously playful tone.

"I said— you could do whatever you wanted to me, Miss."

"Bargaining with me is a dangerous game, Jimin. I've only just started."
