The classroom was still buzzing with the usual end-of-day chatter when Leeseo slumped down in her chair with a dramatic sigh, burying her face in her arms.
âI failed againâŚâ she mumbled into her sleeve, voice muffled and pitiful. âBiology is actually going to kill me this time.â
Next to her, Kyujin, her sharp-tongued but kind classmate, let out a bright laugh. âAgain? Girl, this is like the third time! What happened this round?â
Leeseo lifted her head, pouting cutely as she pushed her long dark hair behind her ear. âI donât know⌠I tried! But between rehearsals, recordings, flights, and fan meetings⌠my brain just turns into mush when I open the textbook at 2 a.m. in a hotel room.â
Kyujin raised an eyebrow, smirking. âAh right, Miss Idol is too busy living the glamorous life. Must be nice jetting around the country while the rest of us normal students actually attend class.â
Leeseo whined and lightly smacked her friendâs arm. âYah! Itâs not glamorous at all! I have extra permission from the school because of my schedule, but that doesnât make studying any easier. I canât even relate to normal student life anymore. While you guys are chilling at home, Iâm practicing until my legs feel like jelly or trying not to fall asleep during meetings.â
She sighed again, deeper this time, resting her chin on her hand. âI feel so behind⌠I really donât want to repeat this subject.â
Kyujinâs expression softened. She reached into her bag and pulled out a neatly organized notebook, sliding it across the desk. âHere. My notes for the last two units. I write everything down super detailed because I know youâll need them later. The latest one is on human reproduction â diagrams, explanations, the whole thing. Super meticulous, even if the topic is kinda⌠spicy.â
Leeseoâs eyes lit up as she took the notebook. âKyujin-ah, youâre a lifesaver! Seriously, thank you so much.â She flipped it open curiously, scanning the pages. The handwriting was clean and organized, with colorful tabs and little sticky notes. âWow⌠your notes are actually really pretty. And detailed.â
She turned another page and suddenly froze, cheeks turning a soft pink.
The current chapter heading in big bold letters: Human Reproduction â Fertilization, Implantation, and Gestation.
There were detailed diagrams of reproductive organs, step-by-step explanations of the process, and even small illustrations showing sperm meeting egg. Leeseo swallowed, suddenly feeling warm.
âUmm⌠this is what weâre learning right now?â she asked, voice a little higher than usual.
Kyujin grinned mischievously. âYep. Mr. Teacher is really going in depth with this unit. Good luck studying that one alone~ Donât think too hard about the diagrams, okay?â She winked playfully.
Leeseo laughed awkwardly, trying to play it cool even as her mind wandered. âY-yeah⌠Iâll just copy these tonight and try to memorize everything. Thanks again, really.â
Kyujin stood up and slung her bag over her shoulder. âNo problem! Good luck with your study session. Text me if you need anything else. And hey â try not to fail again, or youâll end up having private lessons with the teacher. Heâs strict but kinda hot, right?â She giggled and waved. âSee you tomorrow!â
âKyujin!â Leeseo yelped, face burning as her friend left the classroom laughing.
Now alone, Leeseo stared down at the open notebook. The classroom was quiet except for the distant sound of students in the hallway. She tried to focus, copying the notes carefully into her own book, but her eyes kept drifting back to the detailed diagrams and descriptions.
The late afternoon sun filtered through the half-open windows of the third-floor classroom, carrying a gentle breeze that rustled the pages of Leeseoâs notebook. Outside, the lively sounds of school life still continued, groups of students laughing loudly near the sports field, the rhythmic thump of a basketball from the extracurricular club practicing, and distant chatter echoing down the hallways. It felt so normal. So peaceful. Everything Leeseo wished she could experience more often.
She sat alone at her desk near the window, Kyujinâs meticulously organized notebook open in front of her. With a heavy sigh, Leeseo flipped to the next chapter.
Her cheeks instantly warmed. Why does it have to be this unit⌠of all things?
Kyujinâs notes were frighteningly detailed. Color-coded headings, neat diagrams with tiny handwritten labels, arrows pointing to every part, and even small side notes with mnemonics. Leeseo traced her finger along one of the beautifully drawn illustrations of the female reproductive system.
Wow⌠Kyujin really went all out, she thought, biting her lower lip. Look at how she labeled everything so clearly â ovaries, fallopian tubes, uterus, cervix⌠even the clitoris and vaginal canal. Itâs so precise itâs almost embarrassing.
A soft breeze blew in again, cooling her flushed face. She tapped her cheek lightly with both hands, trying to snap herself out of it.
âOkay⌠I wonât fail again. This time I will succeed,â she whispered firmly to herself. âFighting, Leeseo!â
But the more she read, the more her mind wandered. Kyujin had written everything in such an intimate, clinical way â describing how the uterus lining thickens in preparation for fertilization, how sperm must travel through the cervix, and the exact process of implantation.
Leeseo stared up at the ceiling, letting out a quiet âArghhhâŚâ as her face burned hotter. This is too much. How am I supposed to memorize this without feeling weird? Itâs so⌠detailed. The way everything connects, how a manâs⌠thing⌠goes inside andâŚ
She shook her head quickly, ponytail swaying, and forced her eyes back to the page. No. Focus. Youâre an idol. You memorize choreography and lyrics all the time. This should be easy. Just treat it like another script.
The distant sound of students cheering outside floated in through the window as the basketball game continued. Leeseo tried to concentrate again, reading Kyujinâs neat paragraph about the female reproductive organs out loud in a soft whisper:
ââThe vagina serves as the passageway for menstrual flow, intercourse, and childbirthâŚââ
She immediately stopped, pressing her thighs together under the desk. Oh my god, why does this sound soâŚ
Still, she kept going. Page after page. Copying diagrams. Repeating definitions under her breath. The breeze kept blowing gently, turning the pages whenever she lifted her hand.
Leeseo flipped the page, moving on to the next chapter.
A small, involuntary giggle escaped her lips as she took in Kyujinâs notes. Her classmate had gone all out again.. Clean, colorful diagrams of the male anatomy, carefully labeled with arrows pointing to every part: testes, epididymis, vas deferens, prostate gland, and of course, the penis in both flaccid and erect states. There were even tiny illustrative pictures that looked almost too realistic for school notes.
âKyujin-ah⌠you really drew all of this?â Leeseo whispered with a shy laugh, covering her mouth. The breeze from the window fluttered the pages again, as if teasing her.
But as she kept reading, her laughter slowly faded and her curiosity grew. Kyujinâs explanations were incredibly thorough. She described how blood flow increases during arousal, causing the penis to become erect. How the muscles contract during ejaculation. And then⌠the numbers.
Leeseoâs eyes widened slightly.
Average sperm count per ejaculation⌠200 to 500 million sperm cells? she read silently. And the volume can beâŚ
Her thighs pressed together under the desk again. A warm, fluttery feeling spread through her stomach. She imagined the diagrams coming to life in her mind â the way it gets hard, the way it throbs, the way it can shoot so muchâŚ
She quickly shook her head, face burning bright red now. What am I even thinking?! This is so embarrassingâŚ
The classroom was much quieter now. Only the soft rustling of leaves outside and the occasional distant shout from the remaining students on the field remained. The golden afternoon light made everything feel a little warmer, a little more intimate.
Leeseo stared at the detailed cross-section diagram of an erect penis for a few seconds too long before catching herself. She tapped both cheeks with her palms â a little harder this time.
âOkay okay, this is just a biology lesson! Donât get yourself stupid, dummy!â she muttered under her breath, trying to scold herself into focus. âItâs science. Just science. You need to pass this test. Come on, Leeseo.â
She took a deep breath and continued copying the notes, repeating the key terms quietly to herself.
âErection⌠ejaculation⌠seminal fluid⌠sperm deliveryâŚâ
Every word made her shift uncomfortably in her seat. No matter how hard she tried to stay clinical, her young mind kept wandering into dangerous territory. The diagrams were so detailed. Kyujin had even added small notes about sensitivity and duration.
Leeseo let out another soft âArghâŚâ and looked up at the ceiling again, fanning her warm face with her hand. The breeze from the window felt nice against her flushed skin, but it wasnât helping her focus.
Leeseo turned the page again, moving into the section titled âCopulation and Fertilization Process.â
Her eyes scanned the heading, and she immediately felt her whole face heat up like a stove. The diagrams here were even more explicit. Side-by-side illustrations showed the erect penis sliding into the vagina, with detailed cross-sections showing exactly how the vaginal walls stretch and accommodate the thickness. Kyujin had written meticulous notes about natural lubrication â how the body produces slick fluids to make the movement smooth and pleasurable. There were explanations about the dense network of nerve endings in both the clitoris and inside the vaginal canal, how friction creates intense sensations, and how the male penis throbs and pulses during thrusting.
Leeseoâs mouth went dry. She could practically feel the descriptions in her body. A strange, warm, tingly sensation bloomed low in her belly and between her legs. She shifted in her seat again, pressing her thighs tighter together, but it only made the feeling stronger.
Oh my god⌠she thought, her heart beating faster. How does it actually feel when a guyâs hard thing slides all the way in? Does it really get that wet inside to make it easier? And all those nerves⌠it says it can feel really, really goodâŚ
Her cheeks were burning bright crimson now. She fanned her face with one hand while the other stayed glued to the notebook. The gentle breeze from the window did nothing to cool her down.
A soft, embarrassed giggle slipped out despite herself.
âKyujin-ah⌠how did you even study this so detailed?â she whispered with a shy laugh. âYou drew the penis going inside and everything⌠Youâre scary.â
But she couldnât stop reading. The notes went on, describing the rhythmic movement, the way the vagina grips and milks the penis, the building pleasure, and how ejaculation delivers millions of sperm directly toward the cervix. Leeseoâs breathing had grown a little shallower. That curious, fluttery warmth between her legs was getting harder to ignore. She squeezed her thighs again, biting her lower lip hard.
This is just biology⌠just biology⌠she kept repeating in her head like a mantra, but her body wasnât listening. Her imagination kept filling in the blanks with vivid pictures.
She tapped her cheeks again, harder this time. âOkay okay, dummy! Focus! This is science. Youâre not supposed to feel weird about it!â
Still, her eyes lingered on one particular diagram â the moment of deep penetration. Her face was now tomato red. The distant sounds of students outside had almost completely faded, leaving only the soft rustling of the wind and the rapid beating of her own heart.
Leeseo flipped to the next few pages, diving deeper into the Copulation and Fertilization subsection. Her eyes widened as she read Kyujinâs incredibly thorough explanation.
The notes described how the erect penis pushes past the vaginal entrance, how the elastic vaginal walls stretch and grip around the thickness, creating friction. It explained why thrusting is necessary â the back-and-forth movement helps stimulate the many sensitive nerve endings while also helping sperm travel deeper. There were even diagrams showing the angle of penetration and how the penis can reach all the way to the cervix during deep thrusting.
Leeseo let out a nervous little giggle, covering her mouth with one hand.
âWow⌠this is so detailed. What is this, KyujinâŚâ she whispered, half laughing, half mortified. âYou really wrote all of this? Youâre really something elseâŚâ
But the more she read, the more her mind started to wander. Her imagination ran wild.
So⌠this is how babies are made, huh? she thought, cheeks burning hotter than ever. The guy puts it inside the girl⌠and moves it in and out⌠and then he ejaculates⌠all that cum shoots deep inside the vaginaâŚ
Her thighs pressed and rubbed together involuntarily under the desk. A warm, slick feeling was starting to form between her legs. She shifted again, trying to ignore it, but the sensation only grew.
And the lube⌠the vagina gets wet by itself to make it easier for the penis to slide in and out smoothly⌠Her breathing became a little uneven. Then the sperm swims all the way up to the womb⌠millions of them⌠trying to find the eggâŚ
She bit her lower lip hard, eyes glued to the page. The gentle breeze from the window brushed across her flushed skin, but it did nothing to calm the strange heat spreading through her body. Her ponytail swayed as she shook her head lightly, trying to clear the vivid images.
Leeseo you idiot, stop imagining it!
Still, her mind kept going. She pictured the thrusting motion, the fullness, the moment when the man releases everything deep inside⌠filling the womb.
Another soft, embarrassed giggle slipped out. âKyujin⌠youâre going to make me fail even harder with these notesâŚâ
She tapped her cheeks again, a bit desperately this time. âOkay⌠stay composed. This is just biology. Just science. You can do this. Donât be stupid.â
But even as she tried to stay focused and copy more notes into her book, her thighs kept pressing together rhythmically. Her heart was beating faster, and that warm, curious ache between her legs refused to go away.
âAaargh⌠I canât concentrate anymoreâŚâ
Leeseo let out a long, frustrated sigh and closed Kyujinâs notebook with a soft thump. The classroom had grown noticeably quieter. The cheerful laughter and shouting from the sports field had faded away, replaced by the peaceful silence of an almost-empty school. Only the soft rustling of the evening breeze through the windows remained.
She glanced at the clock. It was later than she thought.
âTime to go homeâŚâ she muttered to herself. Quickly, she packed all her books and notebooks into her bag, slinging it over her shoulder. Before leaving, she took one last look at the desk where she had been sitting, her cheeks still faintly pink.
Even as she walked out of the school gates and headed home, the thoughts refused to leave her alone. The sun was already setting, painting the sky in soft orange hues. The streets were calm, with only a few students and office workers heading back.
Why canât I stop thinking about it? Leeseo thought, biting her lip as she walked. Itâs just a bunch of notes⌠just biology. But the way it explained everything â how it goes inside, how it moves, how it feels⌠Aah stop it, Leeseo! Youâre being so weird!
She shook her head multiple times, trying to chase the images away, but they kept coming back. The detailed diagrams. The descriptions of thrusting. The part about ejaculation. Her thighs rubbed together slightly as she walked, and she felt that strange warm flutter again.
âDummy⌠itâs just notes,â she whispered to herself, face warm. âJust. Notes.â
When she finally arrived home, Leeseo kicked off her shoes, washed up, and ate dinner with her family like usual. She smiled and chatted normally, but her mind was elsewhere the entire time. After helping clean up, she retreated to her room, closing the door behind her.
She changed into comfortable loungewear â an oversized t-shirt and soft shorts â and sat at her study desk. She tried to focus on other subjects first: math problems, literature reading, history notes. But no matter how hard she tried, her eyes kept drifting toward Kyujinâs notebook, which was now sitting innocently on the corner of her desk.
Eventually, she gave in and opened it again. The reproduction chapter stared back at her. That familiar warmth returned between her legs.
Why does this keep happeningâŚ? she thought, pressing her thighs together under the desk. Itâs just science⌠but my body feels so strange every time I read it.
With a small sigh, she picked up her phone and texted Kyujin.
Leeseo: Kyujin-ah⌠how do you know all of this?? đ your notes are way too detailed lol. i tried studying but my brain is melting help
She sent the message and stared at her phone, waiting, cheeks still tinged with pink. Even now, alone in her room with the soft glow of her desk lamp, she couldnât fully shake the curious, flustered feeling.
Leeseoâs phone buzzed almost immediately. She quickly opened the chat.
Kyujin: Haha whatâs wrong? Too much for you already? đ I learned a lot from those thick literature books we have in the library + some reliable references from the internet. You know me, I always write everything super detailed no matter the subject. Helps me remember better.
Leeseo stared at the message and sighed, leaning back in her chair. Of course⌠thatâs just how Kyujin is. Her friend had always been the meticulous type â perfect diagrams, color codes, extra explanations. But this particular topic felt like way too much information.
Leeseo: yeahhh itâs a lot đľâđŤ the diagrams are so detailed⌠my brain is overloaded lol
A few seconds later, another message popped up.
Kyujin: Maybe you should browse the internet too about that chapter? There are lots of good explanations and even short videos. Might help you understand it quicker đ
Leeseoâs eyes widened at the wink emoji. Her face heated up again.
Leeseo: videos?? kyujin!!! đ isnât that⌠too much??
Kyujin: Itâs for studying dummy đ Educational stuff only~ You said you need to pass right? Then go learn properly. Good luck tonight~ Donât stay up too late thinking about âbiologyâ đ
Leeseo groaned and dropped her phone face-down on the desk, covering her face with both hands.
âAaahh what is thisâŚâ she mumbled. Her heart was beating faster again. The suggestion to search online made her both nervous and strangely curious. She glanced at Kyujinâs notebook still open on her desk, then at her laptop sitting nearby.
The room felt warmer than usual.
She bit her lip, hesitating for a long moment⌠before slowly reaching for her laptop.
Leeseo stared at her phone for a few more seconds before sighing and grabbing her laptop.
Maybe Kyujin is right⌠I should just look it up properly. For studying. Yeah. Just studying.
She opened her browser and typed âhuman reproduction copulation explainedâ into the search bar. The first few results were normal educational sites. But as she scrolled down, some results became⌠less educational. Clickbait titles mixed with actual medical sites. Out of curiosity, she clicked on one that looked promising.
It redirected her straight to a porn site.
Leeseoâs eyes widened. Her heart started pounding like crazy. She had never visited a site like this before. The homepage was filled with dozens of hot video thumbnails â half-naked women, explicit positions, close-up shots of bodies connecting. Her face instantly turned bright red.
âW-what theâŚâ she whispered, biting her lip hard.
There were so many thumbnails:
A girl in school uniform bent over a desk
A teacher grabbing a studentâs breasts from behind
Close-ups of thick cocks sliding into wet pussies
Creampie shots with cum dripping out
Girls with legs spread wide, moaning faces
The warm feeling between her legs came back stronger than ever. She squeezed her thighs together, but it only made her more aware of the growing wetness in her panties.
This is so wrong⌠I should close it, she thought. But sheer curiosity won. Her hand trembled slightly as she clicked on one of the videos titled: âAfter School Private Lesson â Innocent Student Gets Creampied by Teacherâ.
She quickly plugged in her earphones.
The video started. A cute girl in a school uniform (looking a bit like a cosplay version of herself) was staying late in an empty classroom with her strict teacher. The acting was cheesy, but the scenes were intense.
Leeseo gasped softly as the teacher started touching the girl â groping her breasts, sliding his hands under her skirt, fingering her until she was moaning.
What the hell⌠is this really how it happens? Leeseo thought, eyes glued to the screen. Does it actually feel that good?
The girl dropped to her knees and started sucking the teacherâs cock like she was starving for it, looking up at him with teary, lust-filled eyes. Leeseo gulped loudly, imagining the sensation. Then the girl was bent over the desk. The camera zoomed in close as the thick cock pressed against her wet pussy entrance⌠and slowly slid inside.
âAhhhn~!â the girl in the video moaned loudly.
Leeseoâs face burned red. She could hear every wet sound, every slap of skin, every desperate moan. The male started thrusting harder, deeper. The girlâs moans became louder and crazier.
Leeseoâs breathing grew heavy. Without realizing it, her thighs started grinding together slowly under the desk. That warm, aching feeling had turned into a full throb between her legs. Her nipples felt stiff against her oversized t-shirt.
It looks so big⌠how does it fit all the way inside? she wondered, completely mesmerized. And the way sheâs moaning⌠is it really that pleasurable?
She kept watching as the teacher fucked the student harder, the desk creaking, the girl crying out âSensei~! Harder please!â while her body shook.
Leeseo bit her lip so hard it almost hurt. Her hand unconsciously moved down, resting on her thigh, inches away from touching herself.
She was completely lost in the video now.
As video continues, Leeseoâs breathing was getting heavier. Without thinking, she spread her legs wider under the desk, her soft thighs parting involuntarily. One hand slipped under the waistband of her shorts and into her panties. She was already soaking wet.
âAhâŚâ she let out a tiny gasp as her fingers brushed against her sensitive folds.
On the screen, the teacher was now fucking the student in missionary position on the desk, her legs wrapped around him. Leeseo copied the movement without realizing it â spreading her legs even more as her fingers started rubbing her clit in slow circles.
With her other hand, she lifted her oversized t-shirt and groped her own perky breast, squeezing it gently, pinching her hardened nipple. The sensation made her whimper softly.
Oh my god⌠this is so wrong⌠she thought, eyes glued to the video. But it feels so good⌠What is this feeling?
Every thrust on the screen made her fingers move faster. She watched the teacher flip the girl into doggy style, pounding her harder, the sound of skin slapping filling her earphones. Leeseoâs soft moans started slipping out, quiet, breathy, and needy.
The video kept going. The couple was clearly approaching climax. The male started thrusting harder, deeper, almost feral. The girl was moaning loudly, her body shaking.
âYes! Fill me up, Sensei~!â the girl cried out.
Leeseoâs fingers moved faster, rubbing her swollen clit and occasionally dipping inside her tight, dripping entrance. Her hips rocked against her hand as she watched the male bury his cock to the hilt, bottoming out inside the girl. The female character twitched violently as she came, and the male groaned deeply, pumping his load deep into her womb.
Then he slowly pulled out.
The camera zoomed in on the girlâs gaping pussy â pink, swollen, and leaking thick white cum that dripped out obscenely.
That sight broke something in Leeseo.
Her fingers moved frantically now, rubbing herself intensely while her other hand squeezed her breast harder. Her mouth fell open in a soft, shaky moan.
âHaa⌠ahh⌠oh my godâŚâ
Her thighs trembled. The image of the creampie, the way the cum leaked out, the way the girlâs body twitched in pleasure.. It was burned into her mind. She was so close. Her whole body felt like it was on fire.
Leeseoâs eyes stayed fixed on the screen, breathing ragged, fingers desperately chasing that unknown peak as the warm, slick sounds of her touching herself filled her quiet room.
Leeseoâs breathing was getting heavier and heavier. Short, desperate gasps filled her quiet room as her fingers moved faster between her legs. Her hips bucked slightly against her hand while her eyes stayed locked on the screen â the way the girlâs pussy was still twitching, cum slowly leaking out.
She was so close. That warm, building pressure was getting stronger and strongerâŚ
Just a little more⌠just a littleâŚ
Her phone buzzed multiple times on the desk, snapping her out of the trance.
Leeseo jolted hard, yanking her hand out of her shorts. âHaa⌠haa⌠ah damn!â she whispered breathlessly, eyes wide with surprise.
Her heart was racing. She looked down at herself â one hand still squeezing her breast, her oversized t-shirt pushed up, and her left breast completely slipped out of her bra, nipple hard and flushed. Her panties were visibly soaked, a wet spot clearly visible on her light-colored shorts.
âIâm so messyâŚâ she muttered, face burning with embarrassment. âWhat the hell am I doingâŚ? That touch felt so good but⌠what is this feeling? I feel so weirdâŚâ
She quickly pulled her shirt down and fixed her bra, still breathing heavily. Her thighs were trembling, and that aching need between her legs hadnât gone away. She felt frustrated and guilty at the same time.
With shaky hands, she picked up her phone and opened Kyujinâs messages.
Kyujin: Heyy Donât watch weird things okay? đ Just study properly~ Donât get distracted đ
Leeseo stared at the messages for a few seconds, then let out a long, defeated sigh.
ââŚToo late, Kyujin,â she whispered to herself, cheeks still flushed. âWay too lateâŚâ
She closed the porn tab quickly, but the images were already burned into her mind. The creampie. The loud moans. The way the girl looked when she got filled.
Leeseo hugged her knees to her chest, still feeling that warm, sticky wetness in her panties.
What is happening to meâŚ
The next morning, sunlight streamed gently through the classroom windows as Leeseo sat at her usual desk near the back, staring blankly at the open textbook in front of her. The chatter of students around her felt distant. Her mind kept drifting back to last night â the glowing screen, the loud moans in her earphones, the way her fingers had moved between her legs, and that intense, wet, aching feeling she couldnât forget.
What the hell was I doing� she thought, cheeks warming again. Touching myself like that while watching those videos⌠the way that girl got filled⌠the sounds she made⌠Why does my body feel so weird every time I remember it? Am I really that perverted�
Leeseo shook her head quickly, trying to chase the dirty thoughts away. Her ponytail swayed with the motion.
Stop it, Leeseo! Youâre an idol. You canât be thinking about these things at school!
She took a deep breath and tried to focus on the page, but the words blurred together.
Suddenly, someone poked her shoulder from behind.
âKyaa!!!â Leeseo jumped in her seat, startled.
Kyujin stood there grinning, bag slung over one shoulder. âWhoa, someoneâs so scared today. What were you thinking about so deeply?â
Leeseo forced a smile and laughed nervously, tucking a strand of hair behind her ear. âN-nothing! Just⌠reviewing the notes. Yeah.â
Kyujin raised an eyebrow, amused. âSo? Was my note helpful? Did you manage to study the reproduction chapter properly last night?â
Leeseoâs face instantly heated up. She giggled awkwardly, a little too high-pitched. âAhaha⌠y-yes! It was really helpful. As expected from you, Kyujin! Super detailed and⌠um⌠clear.â
Kyujin stared at her for a second, then burst out laughing. âWhatâs with that nervous giggle, Leeseo? You didnât think about weird things while studying, right?â
Leeseoâs eyes widened. âWh⌠what are you saying?! Of course not!â She puffed her cheeks, trying to look confident. âIâm an idol, you know! I wouldnât do something like that!â
Kyujin smirked, clearly not convinced. âMhm~ Sure, Miss Idol. Your face is all red though.â
Leeseo covered her cheeks with both hands, groaning internally. Please stop teasing meâŚ
The morning bell rang, saving her from more teasing. But as the teacher â you â walked into the classroom, Leeseoâs heart skipped a beat. She looked at me, as Iâm gonna start the lesson in the class
âGood morning, Sir!â they greeted in unison.
I smiled and nodded. âGood morning, everyone. Sit down.â
I started the class as usual, moving on to a new topic â cell division and genetics â instead of continuing the reproduction chapter. I wrote some key points on the board, explaining them calmly while occasionally glancing around the room.
My eyes landed on Leeseo near the window. She was staring at me with a weird, unfocused look â cheeks slightly pink, lips parted, eyes a little glassy. I tilted my head slightly, wondering what was wrong with her.
Maybe sheâs still bothered about failing the last test? I thought. Poor girl has such a packed scheduleâŚ
I continued teaching, but Leeseoâs gaze stayed on me the entire time. She wasnât taking notes like usual. Her mind was clearly somewhere else.
Oh my god⌠why does he suddenly look⌠different?
Every time you moved or spoke, Leeseoâs mind flashed back to the video from last night. The teacher in the video had a similar authoritative vibe. The way you stood in front of the class, tall and calm, made her imagine you in that same position â bending a girl over the desk, thrusting deep, filling her up until cum leaked out.
She squeezed her thighs together under the desk, feeling that familiar warmth returning. Stop it, Leeseo! Heâs your teacher! This is so wrongâŚ
But she couldnât help it. In her eyes, you suddenly looked⌠hotter. More commanding. The memory of the thick cock sliding in and the loud moans kept replaying in her head.
I noticed Leeseo spacing out again. I called her name once.
No response. She was still staring at me with that strange, distracted expression.
I called again, a bit louder this time.
âLee Hyungseo? Leeseo?â
Leeseo jolted in her seat the moment she heard her name.
âYe⌠yes?!â she answered a little too loudly, voice cracking. âAh⌠sorry, Sir!â
The whole class turned to look at her for a second before giggling quietly. Leeseo wanted the ground to swallow her whole.
I looked at her with mild concern, tilting my head slightly. âAre you tired from your activities? You seem a little weird today, Leeseo.â
Her face flushed deeper. She quickly shook her head.
âI⌠Iâm okay, Sir. SorryâŚâ she mumbled, lowering her gaze to her notebook.
Aaah what the heck am I thinking?! I should be focusing on the class, not⌠not that kind of thing! Heâs my teacher! Stop it, Leeseo, you idiot!
I nodded slowly, still watching her for a moment. âAlright. But if youâre having trouble keeping up, let me know.â
The class continued normally for the rest of the period. You explained the new material, but Leeseo could barely focus. Every time you walked near her row or wrote something on the board, her mind kept drifting back to last nightâs video.
Right before the bell rang, I spoke again while looking directly at her.
âLeeseo, after this class, come to the teacherâs room, okay?â
Leeseoâs heart skipped a beat. She swallowed nervously and gave a small nod.
After the bell rang, Leeseo let out a long, heavy sigh. Her heart was still racing. She slowly packed her things and walked toward the teacherâs room, feeling a strange mix of nervousness and that lingering warmth from last night.
She knocked softly on the door.
Leeseo stepped inside. You were sitting at your desk, going through some papers. She stood there politely, hands clasped in front of her.
I looked up and smiled gently. âLeeseo, about your last test⌠you failed quite badly. I know your idol schedule is really packed, so I understand itâs difficult. But if you want to fix your mark, Iâll give you a chance.â
You sighed and leaned back in your chair.
âIâll give you extra classes after school. Iâll help you get through it personally. How does that sound?â
Leeseoâs mind went completely wild the moment you said âextra classes.â
Extra class⌠just the two of usâŚ? Like in the videoâŚ? Will Sir⌠touch me? Will he bend me over the desk like that teacher did? Will he put it inside me andâŚ
Porn scenes flashed through her head one after another â the thrusting, the moaning, the creampie. Her face grew hot. She pressed her thighs together instinctively.
Stop it! Stop thinking about that! Heâs just trying to help you study!
She forced herself to stay composed, bowing slightly.
âY-yes, Sir. Thank you so much for giving me a chance. I really appreciate itâŚâ
Even as she said that, her eyes had a hint of heat in them when she looked at you. She bit her lower lip without realizing it, her gaze lingering on your broad shoulders and hands for a second too long.
You nodded. âGood. Weâll start soon. You can go now.â
Leeseo bowed again. âThank you, SirâŚâ Then she quickly left the teacherâs room.
As soon as she was out in the hallway, she practically ran to the nearest girlsâ toilet. She locked herself in one of the stalls, sat down on the toilet seat, and hugged her knees.
Her breathing was heavy again.
That same heat from last night came rushing back, even stronger. Her panties were getting wet again just from thinking about the private lessons with you.
She bit her lip hard, thighs rubbing together.
What is wrong with me⌠Why does my body keep reacting like this�
Inside the locked toilet stall, Leeseoâs mind was spiraling.
She sat on the toilet seat and slowly spread her legs apart. With trembling hands, she flipped her pleated skirt up onto her waist, exposing her smooth thighs and the cute pink panties underneath.
âAhâŚâ she breathed shakily.
Her right hand moved between her legs, pressing against her pussy through the thin fabric. She started rubbing slow circles over her clit, feeling how warm and wet she already was.
âMmmh⌠ah⌠I need this⌠I need thisâŚâ she whispered softly, voice barely audible.
Her fingers moved faster. The pink panties quickly became soaked, the fabric turning darker and clinging to her folds. The wet patch grew bigger with every circle.
She couldnât stop herself anymore.
With her left hand, she quickly unbuttoned the top few buttons of her uniform blouse, loosened her tie, and pulled her bra up. Her right breast spilled out â quite sizable and perky for her age, nipple already stiff. She groped it firmly, squeezing and pinching the sensitive bud while her right hand kept rubbing her pussy harder.
âHaa⌠haa⌠ahhâŚâ
Mixed feelings flooded her head, like a huge wave crashing inside her. Arousal were so strong it made her dizzy. She also confused... Why does my body feel like this? Guilty feeling⌠Iâm an idol⌠I shouldnât be doing this in school⌠Fear, What if someone hears me? What if someone walks into the toilet?
But the risk only made her wetter.
Her mind drifted back to the porn video again. She imagined you, her teacher, instead of the actor in the video. You bending her over the desk, sliding your thick cock into her tight pussy, thrusting deep while calling her a naughty student.
âAhh⌠SirâŚâ she moaned quietly under her breath, fingers pressing harder against her soaked panties. Her hips rocked forward, grinding against her own hand.
She pinched her nipple harder, imagining it was your hand groping her breast while you fucked her senseless in the empty classroom.
The pleasure kept building. Her soft moans echoed lightly in the stall as she kept desperately touching herself, completely lost in forbidden fantasies.
Leeseo couldnât hold back anymore.
With shaky fingers, she slid her soaked pink panties to the side, finally touching her bare, dripping pussy directly. The moment her fingers made contact with her slick, sensitive folds, she let out a soft, trembling moan.
She started circling her clit faster, the wet sounds of her arousal clearly audible in the small stall. Her breath grew heavier and heavier, chest rising and falling quickly.
In her mind, she was no longer in the toilet stall.
She was bent over her classroom desk, skirt flipped up, while you, her teacher stood behind her, thick cock sliding deep inside her tight little pussy.
Her fingers moved lower. She pushed two of them shallowly inside herself, feeling her walls clench around them.
âAhâŚaaah.. haaa⌠haaaâŚâ she moaned softly, trying to keep her voice down.
âIâm such a naughty idol⌠and studentâŚâ she whispered breathlessly. âI need this so muchâŚâ
Her right nipple was fully erect, hard and sensitive. She pinched and rolled it between her fingers while her other hand kept fingering herself. She bit her lip hard, eyes fluttering as she gazed up at the ceiling of the stall.
The pleasure kept building higher and higher. That warm, coiling pressure inside her belly was getting stronger, almost overwhelming.
This is so wrong⌠I shouldnât be doing this in school⌠she thought, guilt flashing through her mind for a second.
But the heat was too strong. It completely corroded her thoughts. The images of you railing her, filling her up, and pumping her full of cum kept flooding her brain.
She whispered desperately, voice shaky and needy:
âI need something⌠I need something inside me⌠What is it gonna feel likeâŚ? AahâŚâ
Her fingers moved faster, pushing a little deeper. Her hips rocked against her hand as she chased that unknown peak, lost in lust and forbidden fantasy.
Her soft, suppressed moans echoed quietly in the stall as she edged closer and closer.
Leeseo kept desperately playing with herself.
Her fingers moved faster between her legs, rubbing her swollen clit and dipping shallowly into her dripping entrance. Her other hand kneaded and pinched her right breast, rolling the stiff nipple between her fingers. She bit her lip hard, eyes squeezed shut, trying her best to hold back her moans.
But her mind was completely drowned in fantasy.
She imagined you fucking her hard on the classroom desk â your thick cock stretching her, pounding deep, calling her your naughty little student while you filled her up.
âYes⌠yes⌠yesâŚâ she whispered shakily, almost begging. âPlease do it⌠pleaseâŚâ
The tension inside her kept building higher and higher. A strange, powerful pressure grew from deep in her pussy, spreading through her whole body like electricity.
Her eyes suddenly snapped open.
No no no⌠not here⌠not in schoolâŚ!
Her hand refused to stop. Her body betrayed her completely.
Suddenly, the wave crashed over her.
Leeseoâs whole body twitched violently. Her back arched, thighs shaking uncontrollably as her first-ever orgasm ripped through her. Her pussy clenched hard around her fingers, flooding with wetness. Waves of intense pleasure surged through every inch of her body, making her tremble and spasm on the toilet seat.
She pressed her mouth against her arm, desperately trying to muffle the moans that wanted to escape. Small, broken whimpers still slipped out as her body kept twitching with aftershocks.
âHaa⌠haa⌠haaâŚâ
When it finally started to fade, Leeseo slumped back against the toilet wall, breathing heavily, eyes glassy and unfocused.
What⌠what is this feelingâŚ? she thought, still trembling. This is so good⌠so intenseâŚ
Her panties were completely soaked. Her fingers were shiny with her juices. Her right breast was still out, nipple red from how much she had played with it.
She sat there for a long moment, trying to catch her breath, mind spinning.
Oh my god⌠I just came⌠in the school toilet⌠thinking about my teacherâŚ
Leeseo stayed slumped on the toilet seat for a while, completely dazed.
Her chest rose and fell heavily with every breath. Her legs were still spread wide, skirt flipped up messily onto her waist, and her soaked pink panties pushed to the side. Her right breast was still exposed, nipple glistening slightly from her own touch. Her hand hung limply at her side, fingers shiny with her juices.
She stared blankly at the ceiling, mouth slightly open, still gasping softly.
Then the guilt hit her like a truck.
Her eyes widened in shock as reality came crashing down.
Oh my god⌠what did I just do?!
She panicked and quickly sat up straight. Her hands fumbled desperately as she pulled her bra back down, buttoned up her uniform with shaky fingers, and straightened her tie. She fixed her skirt, then grabbed some toilet paper to wipe the mess between her legs. Her panties were still uncomfortably wet, clinging to her sensitive folds.
Why⌠why did I do that? she thought, face burning with shame. Iâm an idol⌠Iâm supposed to be a good student⌠but I touched myself in school⌠thinking about my teacher fucking meâŚ
She cursed herself silently.
This is so wrong⌠so so wrongâŚ
But even as the guilt flooded her, another feeling lingered â that deep, satisfying pleasure still echoed in her body. The afterglow made her thighs tremble slightly.
âŚBut it felt so good, she admitted to herself, biting her lip. Really, really good⌠Iâve never felt anything like that before.
She sat there for another minute, conflicted. Part of her felt dirty and ashamedâŚ
âŚwhile another part already wondered when she could feel that pleasure again.
Leeseo took a deep breath, fixed her hair in the small mirror inside the stall, and tried to look normal before stepping out.
Leeseo took one last deep breath, fixed her skirt one more time, and stepped out of the girlsâ toilet.
The moment she walked out, she froze.
You were standing right there â leaning casually against the window ledge just a few steps away, arms crossed, smiling at her.
Leeseoâs heart nearly jumped out of her chest.
âLeeseo,â I said with a gentle smile, tilting my head. âWhy did you take so long in the toilet? Are you feeling, okay?â
She could feel her face burning instantly. Her legs felt weak.
âIâI⌠I had a stomachache, SirâŚâ she answered quickly, trying to sound normal. âItâs nothing serious. Sorry for taking too longâŚâ
But she looked different. Her cheeks were still flushed, her breathing hadnât fully calmed down, and her eyes couldnât meet yours properly.
I kept smiling, but my gaze slowly drifted down.
There was a small, suspicious wet patch on the front of her pleated skirt. And on her inner thighs⌠a thin, shiny trail of clear fluid was slowly trickling down her smooth skin.
My eyes lingered there for a second before returning to her face. My smile didnât fade, but it gained a slightly knowing edge.
âStomachache, huh?â I said softly, voice calm but carrying a hint of something else. âYou sure thatâs all it was?â
Leeseoâs mind went blank. She instinctively pressed her thighs together, but it was too late.. you had already seen it.
She swallowed hard, trying to keep her voice steady.
âY-yes, Sir⌠Iâm fineâŚâ
But her body betrayed her again â a fresh wave of heat rushing through her as she stood in front of you, panties still soaked, the evidence of what she just did literally dripping down her thighs.
I took a small step closer, still smiling, but my voice dropped lower.
âLeeseo⌠I heard some sounds coming from inside the toilet,â I said calmly, eyes locked on hers. âThey sounded⌠different. Not exactly like someone who just has a stomachache.â
I smirked slightly, tilting my head.
âWhat were you doing in there, Leeseo? You sure you only had a stomachache?â
Leeseoâs face turned pale, then bright red in an instant. Her mouth opened and closed, trying to find words.
âI⌠I-I really had a stomachache, Sir! It was really bad so I⌠I had to⌠um⌠make some sounds to⌠to feel better! Yes! Thatâs it!â
Her excuse sounded ridiculous even to herself. Her voice was shaky, and she couldnât stop fidgeting, pressing her thighs together nervously. The wet patch on her skirt and the glistening trail on her inner thigh became even more obvious up close.
I leaned in a little closer, voice dropping into a low whisper so only she could hear:
ââŚWhat about âYes⌠yes⌠yes⌠please do it⌠pleaseâŚâ?â I paused, watching her reaction closely. âAnd âI need something inside meâŚâ?â
Leeseo felt like she had been struck by lightning.
Her whole body went cold, then burning hot. Her knees almost buckled. The realization that you had heard everything â her moans, her dirty whispers, her desperate begging â crashed over her like a wave.
Her eyes widened in pure panic. She looked up at you, completely frozen, lips trembling.
âSir⌠I⌠I didnâtâŚâ she tried to speak, but no proper words came out. Her mind went blank. Shame, fear, and a strange new wave of arousal mixed together inside her.
She stood there in front of you, panties soaked, thighs slightly wet, completely exposed and caught.
I chuckled softly, stepping just a little closer so my voice stayed low and intimate.
âDoes the reproduction biology subject⌠hit something inside you, Leeseo?â I asked, smirking. âAre you fantasizing about it? Wow⌠I didnât expect you to go that far.â
I glanced down at the obvious wet spot on her skirt and the glistening trail on her inner thighs before looking back at her flushed face.
âIt was just a cross-section diagram and some text⌠and yet your mind drifted that far away from it,â I grinned, clearly amused. âAre you really the maknae of a top idol group like IVE? Doing something like this in the school toilet⌠moaning and begging like that?â
Leeseoâs gaze dropped straight to the floor. She couldnât look at you anymore. Her lips were bitten hard, cheeks burning with deep shame and embarrassment. Her hands gripped the hem of her skirt tightly, trying to hide the wet patch, but it was useless.
He knows⌠He heard everything⌠He knows I was touching myself while thinking aboutâŚ
Her mind was spiraling. She felt so small, so exposed, and yet⌠a dark, twisted part of her felt strangely thrilled that you â her teacher â had caught her like this.
Leeseo stayed silent, biting her lip harder, eyes glued to the floor, too mortified to speak.
I looked at her for a moment, still smirking, then spoke softly but firmly.
âFollow me, Leeseo. Weâre doing your private lesson right now.â
Leeseo nodded weakly, still unable to look you in the eyes. She followed you quietly down the hallway, head lowered, cheeks burning. Her steps were small and hesitant.
As we walked, she whispered barely loud enough for you to hear:
ââŚI was thinking about it so much, Sir⌠I couldnât stopâŚâ
I didnât reply, but my smirk widened.
We reached her classroom. It was completely empty â all the other students had already gone home. I closed the door behind us with a soft click, the sound echoing in the quiet room.
Leeseo walked slowly to her usual desk near the window and stood there, still looking down at the floor. I followed right behind her, stopping close enough that she could feel my presence.
I leaned in and whispered near her ear:
âYouâre already so wet, Leeseo⌠Youâre lucky no one noticed that your skirt is soaked from your panties.â
âAnd your uniform collar is messy⌠some buttons are missing too.â
Leeseoâs breath hitched. She instinctively touched her collar, realizing how disheveled she looked after what she did in the toilet. Her heart was pounding so hard she thought you could hear it..
I stood behind Leeseo, close enough that she could feel the warmth of my body. The empty classroom was completely silent except for her nervous breathing.
âSince youâre having trouble with the reproduction chapter,â I said calmly, voice low, âletâs start with something basic⌠but important.â
I leaned closer to her ear.
âYou know⌠female breasts are very sensitive to touch.â
Leeseoâs breath hitched. I continued explaining in a soft, clinical tone, like a real lesson:
âWhen breasts are touched, especially the nipples, it sends strong signals through the nerve endings. Blood flow increases⌠the skin becomes more sensitive⌠and it can make a girl feel heat all over her body. Some girls even get wet just from their breasts being played with.â
As I spoke, Leeseoâs hands moved almost involuntarily. She loosened her tie and slowly unbuttoned the top few buttons of her uniform again, revealing her cleavage.
I smirked, looking over her shoulder at her chest.
Her breasts were quite sizable and beautifully perky for her age â round, firm, and sitting high on her chest.
I whispered right next to her ear:
âYou want me to play with them, huh?â
Leeseo hesitated for a second⌠then nodded slowly, shyly.
My hands moved from behind her. I slid them under her open uniform, pulled her bra up, and cupped her bare breasts directly. They filled my hands perfectly â soft yet firm, warm, and incredibly perky.
Leeseo let out a slow, shaky moan the moment my hands made contact.
It was the first time a manâs hands had ever touched her breasts. The difference was immediate â my hands were bigger, warmer, and more confident than her own. She could feel every finger as I slowly groped and squeezed them.
I kept massaging her breasts gently while whispering explanations:
âLook how well your body has grown these⌠Theyâre so perky and well-shaped. The nipples are already this hard just from light touching⌠That means theyâre very sensitive right now. This is completely normal during your age. It shows your body is healthy and responsiveâŚâ
I teased her nipples with my thumbs, rolling them slowly, pinching them lightly. Leeseoâs knees trembled. Another soft moan escaped her lips as she leaned back slightly against me.
I continued the âlessonâ in a low voice, praising her while playing with her chest:
âSuch nice size too⌠not too big, not too small. Perfectly perky. They look beautiful when youâre breathing like thisâŚâ
Leeseo was breathing heavily now, completely lost in the sensation of her teacherâs hands on her bare breasts in the middle of the empty classroom.
I gave her breasts one final gentle squeeze before pulling my hands back.
âSit on your desk, Leeseo,â I said softly but firmly.
Leeseo hopped up without thinking. Her legs parted automatically. When I flipped her skirt up, the sights struck me really hard, her pink panties were completely soaked, the fabric dark and sticky, clinging to her swollen folds. A shiny trail of arousal had already dripped down her inner thighs.
I stepped between her spread thighs and flipped her pleated skirt all the way up to her waist.
I let out a low impressed sound.
âWow⌠youâre really wet, Leeseo.â
Her pink panties were completely drenched, the fabric dark and clinging tightly to her swollen folds. A shiny trail of her arousal had even leaked onto her inner thighs.
Leeseoâs face burned with shame, and she instinctively tried to close her legs and cover herself with her hands.
I smiled gently and held her thighs open.
âDonât worry. No need to be shy. Itâs completely normal to get this wet.â
I started tracing slow circles over her soaked panties with my fingers, gently rubbing her sensitive folds through the thin fabric.
âSee this?â I explained in a calm, teacher-like tone. âWhen I played with your breasts, it activated a lot of nerves. The nerves in your breasts and your pussy are connected through your nervous system. Thatâs why breast stimulation can make you this wet down here. Your body is preparing itself for mating⌠for penetration.â
Leeseoâs breath was shaky as my fingers kept circling, pressing lightly against her clit and sliding along her slit.
âThere are thousands of nerve endings right here,â I continued, rubbing a little firmer. âEspecially around your clit and entrance. Thatâs why it feels so intense when someone touches you here. Your body is very sensitive right now⌠and very honest.â
Leeseo let out a soft whimper, her hips twitching slightly against my fingers. She was soaking even more, the wet sounds becoming audible every time my fingers moved.
I kept rubbing her slowly over her panties, eyes locked on her flushed face.
âDoes it feel good when I touch you here, Leeseo?â
Leeseoâs voice came out shaky and breathless.
âY-yes⌠it feels good, Sir⌠It feels really goodâŚâ
I smirked, clearly satisfied.
I finally pulled the panties aside, her pussy was fully exposed â smooth, puffy, shiny with juices. The entrance was small and tight, already fluttering. I dragged two fingers along her slit and they came away coated in clear, sticky wetness.
I let out a low appreciative sound.
âLook at this⌠such a pretty, tight pink pussy. Completely smooth, no hair at all. So cute and neat for a maknae.â
My fingers gently trailed along her slick folds, coating them with her juices. Leeseo shivered and let out a soft moan.
I started explaining in detail while touching her:
âThis is your outer labia⌠and these are your inner labia,â I said, gently spreading her folds open with my fingers. âSee how wet and glistening they are? Thatâs your bodyâs natural lube.â
I slid one finger slowly up and down her slit.
âAnd this little swollen bump right hereâŚâ I circled her clit, âis your clitoris. It has the most nerve endings. Thatâs why it feels so intense when I touch it.â
Leeseo moaned softly, her hips twitching every time my finger passed over her clit.
I spread her labia wider with two fingers, exposing her tight entrance.
âThis is your vaginal opening. Itâs so small and tight right now⌠but it can stretch nicely when properly aroused. This is where a manâs cock goes in⌠and where he can fill you up.â
Leeseoâs breathing was ragged. Soft, needy moans kept slipping out as I kept touching and explaining every sensitive part of her pussy in detail.
I gently circled her entrance with one finger, teasing it but not pushing in yet.
âEvery part of you is so sensitive, Leeseo. Your body is reacting so honestly⌠getting wetter the more I teach you.â
She was trembling on the desk, legs spread wide, uniform messy, eyes hazy with pleasure as her teacher continued the very hands-on biology lesson.
I kept teasing her slick entrance with my fingertip for a moment longer before slowly pushing two fingers inside her.
Leeseoâs eyes widened and a soft, broken moan escaped her lips.
My fingers were warm and thick as they slowly sank into her tight, wet pussy. Her walls immediately clenched around them, hot and silky.
âRelax⌠breathe,â I whispered, pushing deeper until my fingers were buried inside her.
I started moving them slowly, stroking her inner vaginal walls.
âThese are your vaginal walls,â I explained calmly while fingering her. âTheyâre full of sensitive nerves. When theyâre touched like this⌠especially when stretched⌠it creates a lot of pleasure.â
Leeseo moaned softly, nodding weakly.
âY-yes⌠it feels good inside⌠SirâŚâ
I curled my fingers upward, searching for that special spot. When I found it, Leeseoâs whole body jerked.
Her eyes widened in shock as intense pleasure shot through her.
I smirked and pressed against it again, rubbing it slowly.
âThatâs your G-spot,â I explained, still fingering her steadily. âItâs a very special pleasure point inside you. When itâs stimulated properly⌠it can make a girl feel crazy good. Some girls even squirt from it.â
I kept curling and rubbing that spot while my thumb circled her clit at the same time.
Leeseoâs moans grew louder and more desperate. Her tight pussy kept clenching around my fingers, getting wetter with every stroke.
âYouâre so tight, Leeseo⌠Your pussy is gripping my fingers so nicely. Such a good, sensitive girl.â
She was trembling on the desk, legs spread wide, breathing heavily as I continued the very thorough, hands-on biology lesson.
I slowly pulled my fingers out of her dripping pussy, making Leeseo whimper at the sudden emptiness.
I looked up at her flushed face and smirked.
âNext part of the lessonâŚâ
I knelt down in front of the desk, positioned myself between her spread legs, and leaned in. Without warning, I dragged my warm tongue slowly up her entire pussy in one long lick. I lowered my mouth to her, the taste hit first â sweet and musky. I licked long and slow from her entrance all the way up to her clit. Her thighs clamped around my head, trembling violently. Every time I sucked on her clit, her hips bucked and more wetness coated my chin.
âW-waitâŚ, what are you doing? Ahh!â
Her words were cut off by a loud moan as my tongue licked every inch of her soaked folds from her entrance all the way up to her swollen clit. I licked her slowly, thoroughly, savoring her sweet taste.
I pulled back slightly and praised her in a low voice:
âFuck⌠your pussy is so beautiful, Leeseo. So pink, so tight, and so wet. Perfect little idol pussy.â
Then I dove back in, licking and sucking on her folds with more hunger. My tongue circled her clit before flicking it directly.
Leeseoâs thighs immediately squeezed around my head, trembling hard. Her hands gripped the edge of the desk tightly as her body jolted with every lick.
âAhhâŚ! Sir⌠haa⌠ahhnâ!â
She couldnât hold back her moans anymore. They spilled out louder and needier as my tongue explored every sensitive part of her pussy. Every pulse, every twitch of her intimate area was met with my warm, wet tongue.
I groaned against her, the vibration making her jolt again.
âSo delicious⌠and so sensitive,â I murmured between licks. âYour pussy is twitching so much. You like teacherâs tongue this much?â
Leeseoâs head fell back, eyes half-lidded, mouth open in continuous soft moans. Her thighs kept squeezing my head tighter as waves of pleasure crashed through her body.
She was completely lost in the feeling of her teacher eating her out on her own classroom desk.
Leeseoâs moans were getting louder and more desperate. Her thighs squeezed my head tighter as her body trembled uncontrollably.
âSir⌠Iâm feeling it again⌠I think Iâm going to cum againâŚ!â she whimpered, voice shaky.
I smirked against her pussy and kept licking her clit faster, sucking on it gently.
âThen cum for me, Leeseo. Cum on my tongue.â
Her eyes widened in panic.
âWait⌠wait⌠aaahh! Somethingâs gonna come outâ aaahhh!!â
Her back suddenly arched hard off the desk. Her whole body twitched violently as her second orgasm crashed over her â much stronger than the first.
A clear, powerful stream of her juices blasted against my face and mouth. Some of it splashed onto my shirt, soaking the fabric. Her body kept shuddering and jolting as she rode out the intense orgasm, her pussy pulsing and gushing.
When it finally subsided, Leeseo was left gasping, eyes wide with shock and embarrassment.
âOh my god⌠Iâm sorry! Iâm so sorry, Sir!â she panicked, voice trembling. âDid I⌠did I pee on you?! Iâm so sorryâ I didnât mean toâ!â
I pulled back slightly, my face and shirt wet with her squirt. I laughed softly, wiping my mouth with the back of my hand.
âRelax, Leeseo,â I said with a gentle smile. âYou didnât pee. That was you squirting. Itâs completely normal when a girl feels really good. It means you had a very strong orgasm.â
I stood up, still between her legs, and looked at her with warm eyes.
âYouâre amazing, you know that? Not every girl can squirt on her first few times. Your body is really sensitive and honest⌠I like it a lot.â
Leeseo was still breathing heavily, face completely red, staring at you in a mix of embarrassment, shock, and lingering pleasure.
After watching Leeseo squirt and moan so beautifully, my cock was rock hard and throbbing painfully in my pants.
I stood up straight between her still-spread legs and unzipped my pants. My thick 18cm girthy and veiny shaft sprang free, slapping heavily against my stomach.
Leeseoâs eyes widened in pure shock and horror.
She stared at it, mouth slightly open. It was much bigger and thicker than anything she had seen in the porn videos â long, heavy, with prominent veins running along the shaft and a fat, swollen head already leaking precum.
I smirked down at her, slowly stroking my cock a few times.
âSo⌠this is the final lesson for you, Leeseo.â
Leeseo swallowed hard, still staring at it. She had only seen a few cocks in the porn she watched last night, and even those were nothing compared to this. Kyujinâs diagram was just a simple drawing â nothing could have prepared her for the real thing.
âT-That thing⌠is going inside me?â she whispered, voice shaking. âIt wonât fit⌠Itâs way too big for me, SirâŚâ
Her thighs trembled. She looked terrified⌠but at the same time, her pussy clenched visibly, leaking even more arousal onto the desk. A dark, excited thrill was mixing with her fear.
I stepped closer, rubbing the fat head of my cock against her soaked, sensitive folds, coating it with her juices.
âYou said you needed something inside you earlier, didnât you?â I teased softly. âThis is what your body has been craving.â
Leeseoâs breathing was fast and shallow. Her eyes kept flicking between your huge cock and your face, a mix of fear and undeniable arousal written all over her flushed expression.
I grabbed my thick, veiny cock and laid it on top of her crotch, letting her see just how long it was.
The fat shaft rested heavily against her lower belly, the tip reaching far past her navel. Leeseoâs eyes widened even more as she stared down at it.
âSee this, Leeseo?â I said calmly. âThis is how deep itâs going to go inside you.â
Leeseo bit her lip hard, breathing shakily. The size was intimidating. The cocks she saw in the porn last night looked nothing like this â this one was longer, thicker, and much more real. The veins, the heat, the weight⌠it made her stomach flutter.
âP⌠Please be gentle, SirâŚâ she whispered, voice small and trembling. âItâs my first timeâŚâ
I smirked, slowly rubbing my heavy cock along her soaked slit, letting the fat head tease her clit.
âSo youâre not worried about your idol life, huh?â I teased, voice low and amused. âIVEâs precious maknae⌠getting her first time fucked right here on her own classroom desk. Are you really sure about this?â
Leeseoâs mind was a mess.
She thought about her members, her fans, her image⌠but the overwhelming curiosity and burning arousal in her body drowned everything else out. Her pussy kept twitching, leaking more juices onto my cock.
She bit her lip harder, eyes glassy with lust and nervousness.
I kept rubbing my thick tip up and down her slit â from her clit all the way down to her tight entrance, coating my cock with her wetness. Every time the head nudged against her hole, Leeseo let out a soft, needy moan.
Her hips moved slightly on their own, chasing the feeling of my cock rubbing against her.
I leaned down closer, whispering hotly against her ear while still teasing her entrance with my tip:
âTell me again, Leeseo⌠Do you want me to put it inside you?â
I kept rubbing my thick, veiny cock slowly against her soaked pussy, the fat head teasing her clit and entrance repeatedly. I smirked down at her, eyes dark with lust.
âSay it, Leeseo,â I whispered teasingly. âSay what you were moaning in the toilet earlier.â
Leeseoâs eyes widened. Her face turned bright red, almost crimson. Her eyes became slightly teary from embarrassment as she stared up at you.
She bit her lip hard, body trembling. For a few seconds she stayed silent, too ashamed to speak.
I nudged my cockhead against her tight entrance again, pressing just a little firmer.
âGo on⌠be honest. What did you say while touching yourself?â
Leeseoâs breath hitched. Her voice came out small, shaky, and extremely embarrassed:
âI⌠I said⌠âYes⌠yes⌠yes⌠please do it⌠pleaseâŚââ She swallowed hard, voice almost breaking. âAnd⌠âI need something inside meâŚââ
The moment the words left her mouth, her face burned even hotter. Tears of shame pricked at the corners of her eyes, but her pussy clenched visibly around nothing, leaking more arousal onto my cock.
I grinned, clearly pleased.
âGood girl,â I praised softly, still rubbing my thick shaft against her dripping folds. âThatâs exactly what Iâm going to give you.â
Leeseo looked up at you with teary, lust-filled eyes â embarrassed beyond words, but too turned on to stop now.
I kept rubbing my thick, veiny cock up and down her soaked folds, teasing her entrance with the fat head, pushing just slightly in before pulling back again.
âTell me clearly, Leeseo,â I smirked, voice low and teasing. âWhat is it that you want?â
Leeseoâs eyes were getting watery. She bit her lip hard, face burning with shame and lust. Her voice came out shaky and desperate:
âC⌠Cock⌠I need cock inside me⌠I need big cock inside my pussy⌠PleaseâŚâ
The moment she said those filthy words, I grinned darkly.
I positioned the fat head of my cock at her tight entrance and started pushing in slowly.
Leeseoâs eyes widened dramatically.
âWâŚwhat is this⌠AAAAAHH!! It hurts! It hurts⌠itâs stretching me!!â
Her tight virgin pussy struggled to take my girth. Only the tip was inside and she already felt incredibly full.
I kept doing shallow, gentle thrusts, just working the head in and out.
âRelax⌠Itâs just the tip for now,â I cooed, stroking her thigh soothingly.
I slowly pushed deeper. Leeseo screamed again, her back arching.
âAHHHH!! What is this⌠this feels so weird!!â
âItâs normal for your first time,â I explained calmly while still pushing in deeper. âYour vagina is being stretched for the first time. It hurts a little now, but it will start feeling better soon.â
I kept going until I felt the resistance of her hymen.
I paused and looked into her teary eyes.
âThis is your hymen⌠the thin barrier inside. Once I push past it, you wonât be a virgin anymore.â
Leeseo was breathing fast, panicked but also incredibly aroused. Her pussy kept clenching around my cock, leaking more juices even as she whimpered from the stretch.
She looked up at you with watery eyes â scared, overwhelmed, but too horny to ask you to stop.
Leeseoâs mind was racing wildly even as her body burned with need.
What am I doingâŚ? Iâve become such a naughty idol⌠Iâm with a guy much older than my classmates⌠This is so wrongâŚ
But the heat between her legs and the overwhelming arousal drowned out her thoughts. She looked up at you with teary, hazy eyes and nodded weakly.
âIâll take that as a yes.â
âNo turning back now.â
I gripped her hips firmly and pushed deeper, breaking through her hymen in one smooth thrust.
âAaahhh!!â Leeseo cried out, her body writhing on the desk. âIt hurts! It hurtsâŚ! Youâre so big⌠youâre really inside meâŚ!â
She could feel every inch of my thick cock stretching her virgin pussy wide open. The pain mixed with a strange, deep fullness that made her toes curl.
I groaned deeply, savoring the insane tightness.
âFuck⌠this is what it feels like inside you, Leeseo. So tight⌠so hot⌠your pussy is gripping me so perfectly.â
I stayed still for a moment, letting her adjust, then started giving her slow, shallow thrusts â gently working more of my length inside her.
Leeseo moaned and whimpered with every movement, her hands gripping my arms tightly. The pain was still there, but it was slowly mixing with sparks of pleasure as her walls got used to my girth.
I leaned down and whispered hotly against her ear while continuing the slow thrusts:
âThatâs it⌠take my cock like a good girl. Your pussy is swallowing me so wellâŚâ
I kept the pace slow and deep, giving Leeseo long, deliberate thrusts so she could feel every inch of my thick cock stretching and rubbing against her inner walls.
At first she was still writhing from the stretch, but gradually her pained whimpers started turning into soft, needy pleasure moans. She tried to cover her mouth with her hand to muffle them, but it wasnât working very well.
âF⌠Fuck⌠Youâre so big⌠and rubbing inside meâŚâ she moaned shakily, voice breaking.
I smirked, thrusting a little deeper while my hand roamed up to her chest. I pulled her bra higher and groped her perky breast firmly, pinching her nipple as I fucked her.
âThatâs right⌠Your pussy feels so fucking good, Leeseo,â I groaned in dirty praise. âSo tight and wet. Squeezing my cock like it doesnât want to let go. As expected from an idolâs perfect little pussy.â
Leeseo moaned louder despite trying to stay quiet. Her hand was still pressed against her mouth, but her eyes were rolling back slightly from the overwhelming pleasure. Every slow thrust hit deep inside her, rubbing against her sensitive walls and making her body jolt.
I continued groping her breast, playing with her nipple while my cock kept sliding in and out of her at that steady, deep pace.
âFeel that? My cock is stretching you so nicely⌠Your body is taking me so well. Such a good girl.â
Leeseoâs muffled moans kept spilling out as the pain fully melted into pure pleasure. Her hips started moving slightly to meet my thrusts, her pussy getting even wetter around me.
I started speeding up my thrusts, fucking her harder and deeper. Leeseoâs body rocked back and forth on top of her desk with every powerful stroke, her perky breasts bouncing under her messy uniform.
âAhh! Ahh! I feel you so deep inside⌠I feel you so deep inside meâŚ!â she moaned loudly, unable to hold back anymore.
I grinned and slammed in particularly deep, the fat head of my cock kissing her cervix.
âThatâs your cervix, Leeseo,â I explained while continuing to thrust. âItâs the entrance to your womb. Every time I hit it like this⌠it means Iâm reaching the deepest part of you. Thatâs where my cum needs to go if I want to breed you properly.â
Leeseoâs eyes rolled back slightly as I kept pounding that sensitive spot. Her moans turned even more broken and needy.
I smirked down at her, still thrusting steadily.
âNow youâre really enjoying the lesson, arenât you? Do you understand all of this, Leeseo?â
She could barely form words, but she nodded frantically, tears of overwhelming pleasure in her eyes.
âY-yes⌠Sir⌠I understand⌠AHH!! It feels so goodâŚ!â
Her tight pussy kept clenching around my cock as I fucked her harder on her own classroom desk, the wet sounds of our bodies echoing in the empty room.
I kept thrusting deep into her for a few more strokes, then suddenly slowed down and pulled out of her dripping pussy with a wet sound.
Leeseo whimpered at the sudden emptiness, her pussy clenching around nothing.
âLetâs try another position,â I said with a smirk. âOne you might like. Come ride me.â
I sat down on her chair, my thick, glistening cock standing straight up, still rock hard and throbbing.
Leeseo got off the desk weakly, her legs wobbling. She looked a bit unsteady, but I reached out and helped steady her hips.
I guided her over me, pulling her closer until the tip of my cock pressed against her soaked entrance again.
âEasy⌠slide down slowly.â
Leeseo moaned loudly as she lowered herself onto my shaft. Both of her hands gripped my shoulders for support as my thick cock slowly sank back inside her tight pussy.
âAhh⌠haa⌠itâs going in againâŚâ
Once I was fully buried inside her, I held her hips firmly and looked up at her flushed face.
âGo on⌠move up and down. Ride me, Leeseo. Use your hips.â
Leeseo bit her lip, breathing heavily. Her hands stayed on my shoulders as she started moving, slowly at first, then gradually finding a rhythm, her perky breasts bouncing with every rise and fall.
The new angle made her feel even fuller. Her soft moans filled the classroom as she rode her teacherâs cock on her own chair.
Leeseoâs hips moved awkwardly at first, still getting used to the feeling of being on top. But with every rise and fall, she took more of my thick cock inside her.
I groaned in pleasure, hands gripping her waist firmly to help guide her movements.
âFuck, thatâs it⌠Ride my cock just like that,â I praised her with a low, husky voice. âLook at you⌠bouncing on teacherâs dick in your own classroom. Such a naughty little idol.â
I smirked, eyes locked on her cute, flushed face as she rode me.
âYouâre so fucking tight and wet. This position is good for you, Leeseo. You can control how deep it goes⌠and you can grind your clit against me every time you come down. Feel that?â
Leeseo moaned softly, her breathing getting heavier.
âIt⌠it gradually feels good⌠ahh⌠SirâŚâ she whimpered, her hips starting to move a little more confidently even though they were still a bit awkward.
I kept praising her while helping her bounce on my cock.
âGood girl⌠Youâre taking me so well. Your pussy is swallowing every inch. Iâm so lucky to have IVEâs cute maknae riding me like this. Look at that pretty face⌠all red and desperate. So fucking adorable.â
Leeseoâs moans grew sweeter as she found a rhythm she liked. Her hands stayed on my shoulders for balance while her perky breasts bounced right in front of my face.
I kept talking dirty, voice rough with pleasure:
âThatâs it, baby. Use my cock to make yourself feel good. You were made for this⌠such a perfect, tight, breedable little pussy.â
Leeseoâs cute face twisted in pleasure as she rode me, soft moans spilling out nonstop in the empty classroom.
Leeseo kept riding me, her hips slowly becoming more confident. Between her soft moans, she looked at me with a completely red face and whispered breathlessly:
âI⌠I never had a boyfriend before⌠and now Iâm doing this with you⌠This feels weirdly so goodâŚâ
I smiled warmly at her cute confession, then suddenly pulled her closer.
I crashed my lips against hers in a deep, hungry kiss.
Leeseoâs eyes widened in surprise at first, but they slowly fluttered closed as she started kissing me back. She matched my rhythm, her soft lips moving against mine while her hips kept bouncing on my cock.
When we finally pulled apart, both of us breathing heavily, Leeseo looked at me with dazed eyes.
âHaa⌠haa⌠That was⌠my first kiss tooâŚâ she whispered shyly.
I chuckled and gripped her waist tighter, helping her ride me harder.
âGood girl. Youâre doing so well.â
I praised her while thrusting up to meet her movements:
âYour idol training really shaped your body perfectly. Look at how fluid and smooth your hip movements are⌠So fucking sexy. Youâre a natural at this, Leeseo. Your tight little pussy and these pretty hips were made to ride cock.â
Leeseo moaned louder at the praise, her movements getting even better as she rolled her hips, grinding her clit against me with every bounce. Her perky breasts bounced cutely in front of my face as she rode me with increasing eagerness.
Leeseoâs hips started moving faster and faster. She was riding me with more confidence now, her tight pussy sliding up and down my thick cock as her moans grew louder and more desperate.
âSir⌠Iâm gonna cum soon⌠Iâm gonna cumâ!â she whimpered, voice shaking.
I gripped her waist tighter and thrust up to meet her movements.
âLet it out,â I growled. âLet it all out. Cum for me, Leeseo.â
Suddenly her whole body twitched violently.
Her back arched sharply, pushing her perky breasts forward. Her mouth opened in a perfect âOâ shape as her orgasm hit her hard. Her pussy clenched and spasmed around my cock like a vice, squeezing me rhythmically as she came.
I hugged her close, holding her trembling body against me while she rode through her orgasm, still bouncing weakly on my cock.
âFuck⌠thatâs really tight⌠So much, Leeseo,â I groaned deeply, feeling her walls milking me. âGood girl⌠such a good fucking girl.â
Leeseo kept twitching and shuddering in my arms, soft broken moans spilling from her lips as the intense pleasure washed over her. Her juices coated my cock and thighs as she came hard on top of me.
Leeseo gasped for air as her orgasm slowly subsided. She was still sitting on my lap, my cock buried deep inside her, when she suddenly let out a soft, shy giggle.
âIt⌠it feels so goodâŚâ she whispered, cheeks still flushed. âI like this⌠Mmh.â
She looked at you with hazy, sparkling eyes.
âAre you going to teach me other positions too, Sir?â
I smirked, running my hands along her waist.
âLetâs do it from behind then.â
Leeseo slowly lifted herself off my cock with a wet sound, a little wobbly on her legs. I helped turn her around and guided her to bend over her own desk. She gripped the edge tightly, presenting her ass to me.
I groaned in appreciation, spreading her ass cheeks with both hands.
âFuck⌠your ass looks so good, Leeseo. Nice and perky, perfectly shaped from all that dancing.â
I spread her wider, admiring the view â her tight pink pussy still dripping, and her cute little butthole right above it.
Leeseo whimpered, face burning with embarrassment.
âS-Stop it⌠Itâs embarrassingâŚâ
I laughed softly and gave her ass a light squeeze.
âNothing to be embarrassed about. Youâre perfect. Every part of you.â
I aligned my thick, throbbing cock with her entrance again and pushed back inside her in one smooth thrust.
âAhhâ!â Leeseo moaned loudly as I filled her up from behind, her body jolting forward against the desk.
I gripped Leeseoâs hips tighter and started pounding her from behind. The sound of skin slapping against skin echoed loudly in the empty classroom as I drove my thick cock deep into her tight pussy again and again.
Leeseo moaned loudly, her body rocking forward with every powerful thrust.
âAhh! It feels good⌠Sir, it feels so goodâŚ!â
I kept thrusting steadily, reaching one hand around to grope her bouncing breast while explaining in a rough voice:
âDoggystyle is special because it lets me go really deep⌠I can hit your cervix easier like this. And you look so fucking sexy bent over like this â ass up, back arched, taking my cock like a good little slut.â
Leeseoâs moans grew louder and more shameless. Her body was rocking hard against the desk as I railed her.
âThis is so wrong⌠but it feels so good⌠Ahhâ! Keep it up⌠pleaseâŚ!â
She was pushing back against me now, her pussy clenching greedily around my shaft with every thrust.
Then, between her moans, she gasped out:
âMore⌠Get intense with me, Sir⌠PleaseâŚâ
I smirked, slowing down for a moment but still buried deep inside her.
âYou mean you want it rougher?â I asked, voice low and teasing as I gave her ass a firm slap.
Leeseo whimpered, nodding desperately.
The moment Leeseo begged for it rougher, my smirk turned darker.
âAlright then⌠you asked for it.â
I grabbed a fistful of her long hair and yanked her head back, arching her back sharply. At the same time, I started pounding her hard â deep, brutal thrusts that made her entire body jolt forward against the desk with every slam.
The sound of my hips crashing into her ass filled the classroom. I spanked her ass hard, leaving red handprints on her smooth skin.
âAhh!!â Leeseo screamed in pleasure, her moans completely uncontrollable now.
I reached around and slapped her bouncing tits too, pinching her nipples roughly while I railed her.
âYouâre such a dirty little idol slut,â I growled, yanking her hair harder. âLook at you â IVEâs precious maknae getting fucked like a whore on her own desk. Taking my big cock so deep.â
Leeseoâs face was a horny, fucked-out mess â tongue slightly out, eyes rolling back, drooling a little as she moaned uncontrollably.
âIâm⌠Iâm an idol group member⌠from IVE⌠but Iâm doing this⌠this is so wrong⌠but it feels so good⌠aaahn!!â
Her words were broken by loud, shameless moans. She couldnât think straight anymore â just a dripping, moaning mess getting destroyed from behind.
I kept pounding her mercilessly, spanking her ass and tits red while pulling her hair.
âThatâs right, baby. Moan louder. Let the whole school know what a naughty cumslut their idol is. Your tight little pussy was made for this â made for my cock. Gonna ruin you so good youâll never be satisfied with anyone else.â
Leeseoâs legs were shaking, her pussy clenching hard around me as she got lost in the rough pleasure.
I groaned deeply, still pounding her hard from behind, my thick cock stretching her tight pussy with every thrust.
âFuck⌠I didnât expect Iâd actually be fucking Leeseo today,â I growled, voice rough with pleasure. âHaving my shaft buried so deep inside an IVE member⌠you feel so fucking good.â
Leeseo moaned uncontrollably, her body rocking forward with every hard slam.
âI⌠I watched porn⌠about student and teacher⌠last night⌠It looked so arousing⌠ahhn!!â
I laughed, yanking her hair back a little harder as I kept railing her.
âSo you like the age difference, huh? Older guy ruining a cute young idol like you?â
Leeseoâs voice came out broken between moans:
âYes⌠I wished⌠someone could do it for me⌠make me like this⌠turn me into a mess⌠aaahh!!â
I laughed again, spanking her ass hard.
âWhat a naughty girl you are⌠IVEâs innocent maknae secretly wanting to get fucked by her much older teacher. Look at you now, just a moaning mess like a whore while I destroy your tight little pussy.â
I kept pounding her mercilessly, the desk creaking under the force as Leeseo completely gave in to the pleasure, her mind blank except for the feeling of my cock stretching her.
I kept railing Leeseo relentlessly from behind. One hand gripped her waist tightly, the other grabbed the back of her messy uniform like a handle, pulling her back onto my cock with every brutal thrust.
I leaned down, lips brushing against her ear as I whispered hotly:
âNext is the last chapter⌠about breeding.â
Leeseo moaned loudly, her body shaking with every deep slam.
I continued talking while pounding her:
âWhen a man cums inside a woman, he shoots millions of sperm⌠usually 2 to 5 milliliters of thick cum⌠straight into her womb. Those sperm swim up and try to fertilize her egg⌠and thatâs how a girl gets pregnant.â
I smirked, spanking her ass hard again.
âLook at your hips⌠theyâre such a good shape. Your breasts too⌠You look so fucking fertile, Leeseo. Perfect body for breeding.â
Leeseoâs mind suddenly cleared for a moment.
What if he really cums inside meâŚ? What if I get pregnantâŚ? Iâm an idol⌠I canâtâŚ
But the thought quickly blurred again as the intense pleasure of my thick cock destroying her pussy took over.
âAahâ! Aahâ! Iâm scared⌠Please pull out⌠I canât get pregnantâŚ!â she moaned desperately.
But her body betrayed her words. Her pussy clenched even tighter around me as she pushed back against my thrusts.
âBut⌠itâs too good⌠I want to feel it tooâŚ!â
She was a complete moaning mess â scared, guilty, but too addicted to the pleasure to stop.
I kept pounding Leeseo mercilessly from behind, my hips slamming against her ass as I chased my own orgasm. I leaned down, lips right against her ear, and whispered hotly:
âIâm gonna cum inside you, Leeseo⌠Iâm going to fill your womb with my seed.â
Leeseo screamed in panic, her voice breaking.
âAh! Ah! Please! Cum outside me! I canât risk getting pregnantâ!!â
But her body completely betrayed her. Her pussy suddenly got impossibly tighter, clenching and milking my cock greedily as if it wanted exactly what she was begging against. Her hips pushed back against me desperately as she neared her own orgasm.
âHere we go, Leeseo!â
I buried myself as deep as possible, the head of my cock pressed right against her cervix, and started cumming hard.
âAahâŚ. fuck⌠this feels so good!â
Thick, hot ropes of cum blasted deep inside her pussy, flooding her womb. Leeseo screamed, eyes widened in horror even as her body convulsed in pleasure.
âWait.. wait! Aaahhh!! I feel it⌠I feel something warm inside me⌠Youâre breeding meâ!!â
Her own orgasm hit her at the same time. Her pussy spasmed wildly around my cock, milking every drop as she came hard, body shaking uncontrollably.
Rope after rope kept pumping into her. I stayed buried deep, groaning in satisfaction as I filled her completely.
I whispered right against her ear, voice low and possessive, while still shooting the last few spurts inside her:
âYou feel it, Leeseo? Youâre being inseminated by me right now⌠My cum is filling your womb. Good girl.â
Leeseo could only moan brokenly, her body still twitching as she felt every pulse of my cock pumping her full.
I stayed buried deep inside her for a few more seconds, savoring the way her pussy milked every last drop. Then I leaned down and whispered softly against her ear:
âDonât worry, Leeseo⌠You wonât get pregnant. I have emergency pills that can cancel it. You should take one, okay?â
I explained gently while still pressed against her:
âItâs a morning-after pill. It stops the fertilization process or prevents implantation. Youâll be safe.â
Leeseo let out a big sigh of relief, her body relaxing a little.
âYou scared me⌠I canât get pregnant because Iâm still an idol, you knowâŚâ
I chuckled and kissed the back of her neck.
âI was just teasing you a bit, you know?â
I slowly pulled out of her with a wet plop. Leeseo whimpered at the sudden emptiness. A thick mix of her virginity blood, her love juices, and my white cum started leaking out of her stretched pussy, dripping down her thighs onto the floor.
I turned her around gently and sat her on the chair.
Leeseo spread her legs wide, looking down at the messy sight between her thighs. She stared at her swollen, red pussy leaking my cum and giggled softly, still dazed.
âAh⌠this is real⌠Just like the porn I saw when the female gets cummed insideâŚâ
She reached down with one hand, playing with her pussy a little â spreading her folds, watching more cum drip out. Her face was flushed with a mix of embarrassment and fascination.
I reached into my pocket and pulled out a pack of wet tissues. I gently wiped between Leeseoâs legs, cleaning up the messy mix of cum, her juices, and a bit of blood.
Leeseo giggled softly as the cool tissue touched her sensitive, swollen pussy.
âItâs cold⌠and it ticklesâŚâ she said with a shy laugh, squirming a little on the chair.
When I was done, she looked up at me with those big, sparkling eyes and asked softly:
âCan I clean you up too⌠with my mouth?â
I was surprised by how bold she was, but nodded with a smirk.
Leeseo slid off the chair and went down on her knees in front of me without hesitation. She looked up at me for a second, then leaned in and started licking my cock clean.
Her soft tongue ran along my shaft, tasting the mix of our juices. She took the head into her warm mouth and sucked gently, cleaning me thoroughly with slow, careful movements.
I groaned softly, watching IVEâs maknae on her knees, willingly sucking me clean right after I took her virginity.
Leeseo pulled back with a small pop, licking her lips.
âDid I do it right, SirâŚ?â she asked shyly, still on her knees, looking up at you with flushed cheeks.
âMmh⌠it feels so good, Leeseo,â I groaned, gently stroking her hair. âYouâre so cute when you do this. Youâre really good at it already.â
Leeseo giggled around my cock, still eagerly sucking and licking me clean until I was spotless. When she finally pulled back, she gave the tip a little kiss and looked up at me with a playful smile.
She stood up, still giggling shyly as she fixed her hair, straightened her uniform, and pulled her panties back into place.
âThank you for the lesson, Sir,â she said sweetly, cheeks still pink. âI understand everything now. Iâm going to do my best on the next test!â
A few days later, the test results were posted.
Leeseo had passed with flying colors, her score was even higher than Kyujinâs.
Kyujin stared at the paper in disbelief, then turned to her friend with wide eyes.
âHow did you learn so fast?! Tell me your secret!â
Leeseo just smirked, a playful glint in her eyes.
âAh, maybe itâs thanks to you! Donât worry, Kyujin~ Thank you so much for your notes. They really helped me a lot.â
Kyujin narrowed her eyes suspiciously.
ââŚWhy do I feel like youâre not telling me the full story?â
Leeseo only giggled and walked away with a little sway in her step, already thinking about her next âprivate lesson.â
