Professor Choi's Office — Su-hui's Backdoor 1
Word of Su-hui from Mi-jung had left Professor Choi burning. He wanted to sample the rear entrance Mi-jung had already begun to train — and soon. Of course, even without that, Su-hui was delicious enough on her own. A standout beauty at twenty, a body to match… and that lewd streak of hers only made her more appealing. In the end he could not master the urge. That afternoon, he summoned her to his office.
Knock, knock.
"Come in."
"Hello, Professor."
Su-hui pushed the door open and stepped inside. A sleeveless top and a fluttering white tennis skirt suited her perfectly. Those clean, bare legs would have tempted any man to reach out and touch them. He called her over and sat her on his desk — right in front of him where he sat in his chair.
"Professor… it's still… daytime…"
"It's fine. People hardly ever come by the office anyway."
Both of Professor Choi's hands stroked along Su-hui's thighs. Smooth skin, firm muscle — her legs parted a little under his touch.
"Mmnh…"
A low sound slipped from her throat. She ought to have grown used to a man's hands by now, yet her wanton body answered with exquisite sensitivity. She trembled faintly; sweat beaded in the pale valley of her chest, visible between the edges of her sleeveless top. Slowly he reached up and slid the straps down off her shoulders. They slipped to her elbows, baring her bra. Her full, beautiful breasts rose and fell with every breath — as tempting as ever.
"No matter how many times I look… you're truly lovely, Su-hui."
"Haa… Professor…"
The clasp of her bra came undone, and her pink nipples played under Professor Choi's fingers. He knew exactly where she was sensitive — tugging, pinching, working them with deliberate pressure.
"Aang… aaah… if you touch me like that… haa…"
She jerked at every brush of his fingers. Perched on the edge of the desk, she let him toy with her. Then his tongue found her breast.
"Hauk…"
His tongue circled her nipple roughly. Slick with spit, the bud bent and flattened under the wet pressure. He worked both nipples with stubborn focus until Su-hui caught his hand and guided it down between her legs.
"Aang… Professor… look here… already like this…"
Using his fingers, she stroked her own pussy. Wetness seeped out and left his fingertips sticky.
"Heh… so now even just playing with your chest makes you drip, Su-hui?"
"Haa… Professor… I think I've gotten strange…"
"That's ideal. Means I can shove my cock into you anytime."
"Aaah… Professor… I'm soaked…"
Her legs opened wider. In a shameless pose she hooked her panties aside and showed him her pussy — then peeled the wet fabric off entirely. The panties dangled from one ankle.
"Auh… it's weird… I get wet so… fast…"
"Hoo…"
The zipper of Professor Choi's trousers opened, and his swollen cock sprang free.
"Aaah… Professor… your cock… it's huge…"
Knock, knock.
Someone rapped on the office door. Startled, Su-hui scrambled down and hid beneath the desk.
"Who is it?"
"Professor, it's me — the department assistant."
It was the same teaching assistant who had been training Su-hui. Professor Choi glanced down at her tucked under the desk.
"Come in."
"Hello, Professor."
"Right. What is it?"
"Ah — I had a question about the materials for the next class."
Apparently he had come to ask about the setup for the upcoming lecture. While listening, Professor Choi seized Su-hui by the hair and pushed his cock into her mouth.
"Mmph—"
Listening to the conversation between Professor Choi and the Department Assistant, Su-hui sucked him. The feeling was strange. Both men had already fucked her thoroughly. Hearing their ordinary work talk while she knelt under the desk with the professor's cock in her mouth sent a twisted thrill through her. Secretly licking him, she reached down and rubbed her own pussy. It was already slick enough to glide under her fingers.
"All right then. Handle it as you see fit."
"Understood, Professor."
"Kh— ahem."
"Are you… not feeling well?"
"Mm… might be coming down with something… You can go."
"Yes, Professor. Please take care of yourself. I'll see you in class."
The Department Assistant closed the door behind him.
"Pah…"
Su-hui, who had been sucking him and touching herself the whole time, finally let out a breath. Professor Choi had nearly made a real sound. He was the one who had put his cock in her mouth — but he had not expected her to suck so devotedly while masturbating. That cough during the conversation had been pure reaction to the sight of her working herself under the desk.
"What a filthy little student… sucking her professor's cock and getting herself off…"
"Aang… Professor… my pussy is so… hot…"
"Come to think of it, you and that assistant are fucking too, aren't you, Su-hui?"
"…Yes…"
"Heh… Maybe I should arrange a nice little gathering one of these days."
A threesome, perhaps. Professor Choi smiled at her at his leisure. Su-hui pictured herself caught between the two of them, taking both cocks. She had already slept with each man separately — but the thought of taking them at the same time lit her up with filthy heat.
Professor Choi lifted her back onto the desk. She spread her legs for him without being told. Between those M-spread thighs, her pale pussy was dripping freely. He stood, stripped off his trousers, and pulled her top the rest of the way off. He started to remove the skirt as well, then decided the shoes would only get in the way and shoved it up around her waist instead. Sitting on his desk in nothing but the hiked-up skirt and her sneakers, legs open — she was unbearably appealing. Those M-spread legs looked smooth and firm. Even seated, there was not an ounce of softness on her; that sleek belly and those springy breasts made him want to keep her chained in the office and fuck her all day long.
Hmm… chain her up and fuck her all day? Not a bad idea at all.
"Su-hui. Spread your pussy."
"Aaah… th-that's…"
She sounded embarrassed, but her hands went down and opened herself. A string of wetness stretched from her folds. The soft pink outer lips parted to show the redder flesh within. Inside and out, she was already pickled in her own juices.
"Getting this wet just from sucking your professor's cock… what a filthy student you are."
"Yes… Professor… please… punish me with your cock…"
His thick cock sank into the pussy she was holding open for him. Seated as she was, the thrust drove him all the way to her depths in a single stroke.
"Hauk… s-so deep… aang… the end… you're hitting the end, Professor… haang…"
"Kh… when it comes to pussy, yours really is the best, Su-hui."
"Aang… ang… too big… your cock, Professor… aaah…"
Schlick, schlick.
Wet sounds filled the room as Professor Choi worked his hips. His cock slid halfway out, then drove back in, churning her thoroughly. Already wound tight from sucking him, her pussy clenched and clung. He fucked into her and sucked at her breasts at the same time. Her back arched.
"Haak… ah… aang… auh… aang—"
"Sensitive nipples, just like always."
"Hauk… ang… i-it feels… so good…"
Her juices frothed white and sticky along his shaft.
"Auh… Professor… this is… too deep… you're hitting the end… it feels like you're stabbing my womb—aaah…"
He snapped his hips faster. Still taking him with her legs spread, Su-hui unbuttoned his dress shirt and licked at his nipples.
"Kh—"
"Ang… ang. Professor… haang… I'll make you… auh… feel good… haaah…"
Legs open around his cock, she pleasured his chest. The play of her tongue on his nipples brought him right to the edge.
"Kh— Su-hui, I'm coming."
"Ang… aung… ah… auh…"
"Your mouth. I'll come in your mouth."
After a few hard final thrusts he dragged her down off the desk, seized her by the hair, and shoved his cock roughly between her lips. Instinctively she bobbed her head, turning her mouth into a substitute pussy ready to catch his load.
"Kh—"
His cock swelled and poured cum straight down her throat.
"Kek… kuh… kh—"
There was so much she choked on it. Then her throat worked and she swallowed every drop.
"Hoo… that mouth-pussy of yours is first-rate too."
"Haa…"
She went back to licking him clean — his cock a mess of cum and her own juices.
"Heh… looks like you've gotten very used to sex, Su-hui."
"Haa… I love it so much, Professor… having sex…"
"Heh heh… From what Mi-jung tells me… that back hole of yours has been coming along too, hasn't it?"
"Ah… it's still… a little… scary…"
Sucking him as she glanced aside, faintly shy — the look was new on her. She had always been able to feel it back there; he wanted to see just how far she had come. He pushed her up onto the desk again.
"Turn around. Lift your ass."
"Ah… Professor… it's still… embarrassing…"
"Now."
Su-hui climbed onto the desk and settled on all fours like a cat. From his chair, Professor Choi found himself eye-level with her pale, luscious backside. Below, her pussy gaped slightly from taking him, juices still running; above it, her pink anus twitched.
"I wonder how this pretty little hole has changed… I'm dying to know."
"Aaah… Professor… gently… it's embarrassing…"
She said she was embarrassed — yet the way her pussy and anus kept clenching looked an awful lot like anticipation. The cock she had been sucking felt like it was hardening all over again.
"Heh… Shall I touch it?"
Professor Choi raised his index finger and pushed it into her pussy.
"Hauk—"
He coated the finger thoroughly in her wetness. A few strokes in and out left it slick enough.
"All right then… here we go…"
He gathered the juices from her outer lips as well and carefully smeared them around her anus.
"Aang… ang… it tickles… haang…"
Su-hui's pink hole fluttered.
