Professor Choi's Special Lecture
Professor Choi sat in his research office on campus, eyes fixed on the glowing screen of his phone.
—Huuuugghhh! Haaang! Pull… pull it out, aaang! I-it’s driving me crazy… ugh… s-same… a… haaang… I’m gonna c-come… ugh
The phone screen played the scene of Lee Su-hui moaning as she took in the cock. It had been recorded only a short while ago on the stairs. Professor Choi watched her lewd cries, his own cock hardening in his hand, stroking furiously. The louder her broken voice grew, the faster his hand moved. Finally, he could hold back no longer and let out a deep groan as he came.
“Huu… Lee Su-hui…”
Once he had tidied his disheveled clothes, Professor Choi prepared to enter the lecture hall. Today’s class was the major Su-hui herself had chosen—the one he had been waiting for.
—Buzzing and murmuring
—Hey… Professor’s here.
Professor Choi stepped into the lecture hall filled with students and began the class. Walking among them, his gaze eventually locked onto Su-hui. Unlike the hazy, lust-drunk eyes from the stairs, hers now shone with clarity.
‘Huu…’
Professor Choi found himself overlaying the lewd face of the girl from his phone onto her elegant features. He wanted nothing more than to grab her by the hair, yank her up, and pound her like a dog. With textbook in hand, he moved through the students delivering his lecture.
—Clunk, clunk
Stopping beside Su-hui, he placed a hand on her shoulder.
“Su-hui, would you mind reading the next paragraph for me?”
“Yes, Professor.”
Su-hui answered in her clear, soft voice and began to read. No one in this room could imagine that the same girl who now spoke so politely was the one who had moaned lewdly while shaking her hips on the stairs. When Professor Choi realized this, his groin felt heavy. He returned to the lectern, masking his arousal. As he continued the lecture, he pondered how best to prepare for her later. He had no legitimate reason to summon her right now.
‘Ah… the class roster was here.’
After the lecture, back in his office, Professor Choi retrieved the student roster the assistant had brought earlier. It listed basic information and contact details for the class.
“Lee Su-hui… Lee… Su…”
Scrolling down, he located her number and sent a text.
—Su-hui, it’s Professor Choi. Do you have a moment?
A reply came shortly.
—Yes~ Professor, I’m fine. What is it?
—I saw someone on the stairs last Saturday, but… the sight was rather inappropriate…
“Oh… could it be…?”
“It’s better to send a photo than to describe it… I already sent it via text. Will you check?”
Su-hui’s trembling fingers opened the message.
Her own image stared back—head tilted upward, collar pulled taut, hips filled with the assistant’s cock and fingers. Everything felt over. She had been caught by a professor of all people.
“P-Professor… this is…”
“Huu… Su-hui… it seems we can’t discuss this over the phone… Come to the office this evening.”
“Y-yes… Understood…”
——
That evening, Su-hui stood before the door to Professor Choi’s research office, heart pounding.
—Knock, knock
“Enter.”
—Creak
“Su-hui has arrived!”
Professor Choi sat at his desk.
“Professor… I…”
“Su-hui, why did you do that?”
“…I’m sorry…”
“This… this is almost grounds for expulsion…”
“P-Professor…”
Professor Choi swept his sticky gaze over the trembling Su-hui, head bowed. The thin see-through blouse revealed the black bra beneath. Her black skinny jeans hugged her smooth, long legs.
“This… if anyone else had seen it, you’d be expelled.”
“Ah… Professor, that’s not—”
Professor Choi reached out, picked up the phone, and played the video again.
—One finger alone can grip so tightly! Su-hui’s asshole
Haa! Hah… aaang… b-barely… aah! M-mine… f-fuck
“P-Professor…”
In the video, Su-hui lewdly shook her hips. The office fell silent except for the moans echoing from the phone.
“You don’t want to be expelled, do you, Su-hui?”
“Y-yes…”
Professor Choi rose slowly and approached the door. He locked it with a decisive click. Su-hui instinctively understood what he wanted. He wanted her body. From the phone, the sound of Su-hui taking cock continued to play. Standing with her back to the desk, Professor Choi’s erect cock was clearly visible. He eyed her with hungry intensity, as if about to rape her right there.
“P-Professor… I…”
“Su-hui… you know what I’m going to say, don’t you?”
“Y-yes…”
Su-hui closed her eyes tightly, then opened them. She had already had sex with many men and engaged in lewd acts with peers her own age. But facing a mid-forties professor… it was different.
Slowly, Su-hui began to remove her blouse. The thin white see-through fabric slipped away silently. The soft, full breasts pressed against the black bra came into view. Professor Choi wanted to tear them off immediately, but he held himself back. The best things taste best when hunger peaks.
Finally, Su-hui unbuckled her pants and began to slide the skinny jeans down her thighs. The matching black panties appeared first. The jeans slid further, revealing the curve of her firm buttocks and the plump mound beneath. The fabric continued down her smooth calves, past her narrow ankles, and finally pooled beside her. In Professor Choi’s office, before her professor, Su-hui stood in nothing but her underwear.
“You’ll have to remove the rest as well, Su-hui.”
“Y-yes…”
Su-hui unclasped her bra and let the garment fall. Her breasts swayed freely as the straps slipped away. Embarrassed, she covered one with a hand while clutching the panties, hesitant. This was the very last piece of clothing. For some reason, stripping now felt like crossing an uncrossable river.
“What are you doing, Su-hui? Shall I help you?”
“Ah… n-no…”
Su-hui hesitated, then slid the panties down. She covered her breasts and sex with both hands, turned her head away, and stood with a flushed face. Even this was unbearably beautiful. Her flawless face, slender yet curvaceous body, and now her exposed, lewd personality. Professor Choi would soon strip away that shyness and reveal the slutty nature beneath.
“Hands away.”
His tone had become pure command. Su-hui’s trembling hands moved from her breasts and sex.
“Wow… your pussy is completely hairless?”
Professor Choi admired Su-hui’s bare mound, eyes wide. The angle in the video had hidden the details. He lifted the phone and held it before her.
“That lewdly moaning Su-hui… why does she look so ashamed now?”
“P-Professor… please…”
“It’s fine, Su-hui… I’ll help you.”
Professor Choi set the phone playing Su-hui’s video on the chair and retrieved a vibrator from the desk.
“Hehe. Getting older, it’s hard to satisfy a young wife, so I had to buy this.”
He turned it on. The dildo-shaped vibrator began to hum. Su-hui felt her mind drift. The phone continued playing her own lewd moans and conversation. Professor Choi approached with the vibrating dildo in hand, his naked body erect before her.
“P-Professor, wait a moment…”
Professor Choi ignored her words and stepped right up. He pressed the buzzing dildo against the area between her thighs, right above her sex.
—Uuuu wing
“Hiiik!”
“First… you need to get wet… it won’t be tight if you do?”
“Hiiip…”
—Haaang! Aaaang! Master! Haaang! Now… haaang.
“Master,” Su-hui said, correcting herself.
“Aaaang! Aaaang! Master… haaang… it’s gonna c-come again. Aaaang!”
The phone played Su-hui’s moans and the assistant’s voice.
“How many Masters can our Su-hui have… Shall we try something today?”
“Hiiip… P-Professor… please…”
From the phone came her lewd moans and dialogue. The vibrating dildo trembled against her sex, sending waves of pleasure. Slowly, her pussy began to grow wet.
“Hah… hiiik… huug… Professor…”
“It’s all right, Su-hui… feel however you like. This is our secret. The video too.”
“Haaang… hiiip… huung…”
—Uuuu wing
Professor Choi increased the vibrator’s intensity. Su-hui clamped her mouth shut, fighting hard, but her body began to tremble. Her pussy, already knowing pleasure, grew hot and wet despite her will.
Su-hui, naked with the dildo buried between her legs, moaned. Professor Choi watched her nipples harden and smiled. Seeing how aroused she was, he pressed the vibrator harder, moving it closer to her sex.
“Aaaang… ugh… eeeng… ugh…”
