Professor Choi's Laboratory
The end of the second semester for the first-year students was drawing near. Several subjects had already finished their lectures early, giving the students a bit of breathing room. Su-hui was in the same situation, as two light general-education courses had been dropped from her schedule, leaving her with frequent days without lectures. She had encountered Professor Choi on campus.
"Hello."
"Uh, yes, Su-hui."
Su-hui tried to pass by after the greeting, but Professor Choi caught her.
"How many lectures tomorrow?"
"Ah... none tomorrow."
"Is that so? Then come to my office early in the morning."
"...Yes, Professor."
For the first time in a long while, she headed to Professor Choi's office. The memories of everything she had done with Professor Choi there made her pussy burn with heat.
To keep her appointment with Professor Choi, Su-hui left home early that morning. Her thick-knit sweater dress clung to her curves, revealing every line of her body. Smooth, long legs wrapped in black stockings and finished off with high heels. She covered her body with a light outer jacket.
Clack, clack.
Arriving at school with the sound of her heels, the campus was still empty at the hour before the first class of the day. With a mix of tension and excitement, Su-hui reached the floor where Professor Choi's office was. She knocked on the door.
Knock, knock.
"Come in."
"Hello, Professor."
"Ah, Su-hui has arrived!"
Su-hui stood in front of Professor Choi's desk. She slowly slipped off her outer jacket. The knit dress underneath hugged her body. Although it had some thickness, it failed to hide every curve of Su-hui's figure.
As expected...
Professor Choi smacked his lips.
"Want me to lift your clothes up?"
"...Yes."
Following Professor Choi's words, Su-hui lifted the hem of her dress with both hands. The knit dress slid smoothly upward over her black pantyhose. Her expression was slightly flushed. Yet she continued to pull the fabric up without turning her head, her gaze fixed on Professor Choi. The knit dress that had reached her knees rose higher, exposing her firm thighs, and soon the thin strings of her panties became visible.
Su-hui's underwear is so...
"Isn't it beautiful?"
Su-hui, still gripping the ends of the dress with both hands, spun her body around.
Clack, clack.
Only a single thin string now covered the center of Su-hui's tempting backside. Through the black stockings, her firm buttocks were clearly visible.
More erotic than before...
"Hng... it's because Professor taught me so much."
Professor Choi beckoned Su-hui with a gesture. Still holding the rolled-up dress, she approached and stood beside him. Professor Choi's hand swept slowly up the area between Su-hui's thighs.
Swish.
Under the smooth sensation of the stockings, the outline of her pussy was felt plainly.
"Hyeup..."
Her body had become so sensitive...
Professor Choi stretched out his index finger and began rubbing the center of her pussy back and forth.
Swish, swish.
"Haa... ugh..."
Su-hui's hands, gripping the dress, tightened. Instinctively, she tried to press her legs together.
Whoa... you have to spread them more.
"...Yes... ugh... Professor..."
Swish, swish, swish.
Professor Choi's index finger pressed firmly against Su-hui's pussy and moved quickly.
"Hueh... ugh..."
Su-hui trembled with each motion. The continued finger play made her pussy grow wetter with arousal.
Tzuuk... tzuuk...
"You lewd girl, you're already soaked?"
"Haa... I'm sorry, Professor..."
"Sit on the desk."
Professor Choi directed Su-hui. Obediently, she climbed onto the desk. Professor Choi, seated in the chair, turned to face her and sat. He grabbed Su-hui's knees on both sides and slowly spread her legs apart.
"Aah... Professor..."
Her smooth legs parted wide. The lewd string panties, barely covering her pussy, were visible beneath the black stockings. Professor Choi slowly rubbed the area near her pussy with his thumb, up and down. Thanks to the earlier stimulation, the skin around Su-hui's pussy had already warmed and flushed with heat. He pulled the hem of the dress that she still held in both hands all the way up to her mouth, exposing her flat, slender belly.
Suck.
Su-hui sat with her legs spread on Professor Choi's desk. She bit the lifted hem of her dress in her mouth. Her freed hands now supported her body from behind. Professor Choi's fingers rubbed rapidly over the pantyhose.
"Huep... ugh... ng... uueh..."
Each time Su-hui's heel-wearing foot twitched, her body jerked and her legs dangled in the air. Su-hui's face, with the dress hem in her mouth, flushed bright red. Soon, the overflowing arousal from her pussy seeped through the thin string panties. Professor Choi's fingers left a trail of her wetness across the stockings.
Just from touching, you've gotten this wet.
A slick sheen of arousal glistened on the smooth stockings. Professor Choi reached out with both hands and tore the crotch of her stockings apart.
Ziiik, ziiik, ziz.
"Hng... ugh..."
Through the torn stockings, the lewd panties beneath were soaked and glistening with arousal and saliva. Professor Choi leaned forward and licked beside her pussy.
Hyeut...
His sticky tongue wiped away the arousal that had seeped from Su-hui's pussy. Su-hui's waist swayed gently in response. Professor Choi's finger gently pulled aside one side of her panties. While pulling, he used one hand to stretch the skin beside her pussy outward, causing Su-hui's pussy—laden with arousal—to open slightly with a wet sound. Professor Choi's tongue grazed lightly over her clear, pink pussy, which was spread open and glistening with transparent arousal.
Hyeut... ah... aah...
The tongue that had merely brushed the surface slowly pushed deeper. After lightly touching only her clit, it then licked gently left and right across her pussy lips. Watching Su-hui's reactions grow more intense, the tongue pushed even deeper. Eventually, it plunged fully into her pussy hole and spread her pussy lips wide open from both sides, licking all the way up to her clit.
Hyeut... Professor...
Su-hui's mouth, still biting the hem of her dress, released it. Professor Choi pressed his mouth firmly against her pussy.
Su-hui... has no patience at all?
"Ait... if you lick it like that... hyeut... ah... ah..."
"Today we'll have to give you patience training."
"...Uh huh... what?"
Professor Choi opened the drawer and pulled out two small egg-shaped vibrators.
"Stand and lean against the wall."
"Yes... Professor."
Su-hui, whose pussy was already thoroughly soaked, rose from the desk. She stood facing the window wall and leaned against it.
"Should I take a better pose?"
Following Professor Choi's words, Su-hui pushed her hips backward. Her long legs on the high heels and her pussy—already messy with arousal and saliva—were presented toward Professor Choi.
"Aah... Professor... hick..."
"Why?"
"Hurry..."
Whoa...
Professor Choi approached Su-hui and thrust two fingers into her pussy.
Thud.
"Haa..."
"Just with your hands... and mouth alone, you've gotten this wet... you lewd student?"
"Haa... yes, Professor... please... fill me..."
"Huhu..."
Thud, thud, thud.
"Hueh... ng... aah... ugh... Professor... I can't hold it... please put it in... ugh... ng... aah..."
Su-hui's hips moved instinctively up and down. She was already boiling and eagerly waiting for Professor Choi's cock.
The way your hips move... you're just like a whore."
"Hyeut... ng... Professor... ugh... hurry... please put it in... ng..."
Professor Choi pulled his fingers out of Su-hui's pussy. He rubbed his glistening fingers around her anus.
"Haa... ah..."
Professor Choi lifted the egg-shaped vibrator he had taken out earlier.
"One in your pussy, and one in your ass."
"...Yes?"
Uuuung.
The vibrator sank deeply into Su-hui's pussy, which had been waiting for Professor Choi's cock.
"Uyeut... ugh..."
Even though it was a small egg, the deep insertion made Su-hui clench her legs and tremble. The vibrator, now wet with her arousal, pushed into her back hole.
Since it's slippery, it slides in easily...
Uuuuuung.
"Hyaang... ah... uyeut... Professor... hick..."
Su-hui, with vibrators inserted in both holes, gripped the wall for support and barely held on. The small remote control attached to the vibrator dangled from her pussy and anus.
"Hum... I should secure it?"
Professor Choi took tape from the desk and stuck the remote control to Su-hui's hips and thighs. The remote control sticking out between the torn stockings looked lewd and provocative.
"Hyeut... Professor... aah... ng... ait..."
Su-hui moaned from the deep vibration of the vibrator inside her pussy and anus. Professor Choi's cock, watching the sight, was already throbbing hard enough to tear through his pants. He unzipped his pants and grabbed his cock, shaking it.
"Hu... I was going to hold it since lecture starts soon..."
"Ng... aaang... Professor... ugh... ng..."
Professor Choi grabbed Su-hui's hips, rubbing his cock against her ass and shaking it up and down.
Thud, thud, thud, thud.
"Hyeut"
"Aah... Professor... ugh... pull it out... aah... put your cock in... hyueh..."
"No good... no good... you have to hold back, Su-hui."
When Professor Choi's stiff cock touched her ass, Su-hui grew even more excited. She desperately wanted to spread her pussy and take the cock inside. But Professor Choi only rubbed his cock against her ass while masturbating. The torn stockings, the vibrators buried in her pussy and anus, and the dizzying lines created by the high heels all made Su-hui's backside look lewd and shameless. Professor Choi grabbed her waist as she thrust her hips back and trembled, shaking his cock. Soon, he erupted, shooting his semen onto Su-hui's ass.
Gulug, gulug.
"Haa..."
"Ait... ah... aah... it's warm... ah... Professor... hyueh... ng... aaang..."
Uuuuuung.
The unrelenting vibration of the vibrator caused a gush of arousal to squirt from Su-hui's pussy. The moment Professor Choi's semen landed on her ass, the flood of arousal flowed down. It ran down her thighs beneath the stockings.
"Hu... still, it's lucky I pulled out one last time."
"Hyueh... Professor... pull it out... this... aah... ugh..."
Professor Choi looked at the pleading Su-hui and began to tidy his clothes.
"Then I'll go because I have lecture..."
"Professor... no... hyueh... ng... aaang..."
Uuuung.
"Stay holding it until after lecture is over."
"Ahk... no... please... hick... hyueh..."
"A good student obeys the rules, right?"
"Hyueh... aaang... ah... hyueh... ng..."
Professor Choi left after closing the door.
