Chapter Text
The sun hung low in the horizon, lighting the campus with hues of magenta and violet. The halls and classrooms were silent, all the students and teachers long gone for the weekend.
Well, almost all.
“Nng♡…haa…♡”
Soft gasps and sweet wet noises echoed in the otherwise silent classroom. All the lights in the classroom and halls were off, only the faint light of the sunset illuminating the girl. If someone were to look into the classroom through the window on the door, they would see the silhouette of her petite frame straddled on the corner of a desk, her cotton panties bunched at her knees.
“Mmh~~♡ I-I need to hurry…ahn…♡” Manami pressed her clit to the corner of the desk again, her juices dripping onto the wood. “S-Someone might—ahn~~! ♡”
She was almost sure there was no one left on campus at this time. She had enough late-night chemistry experiments to know that much. But the thought of getting caught made a new wave of arousal wash over her straight to her weeping cunt. She clenched the hem of her navy skirt, hitching it higher to grind her hips harder against the corner of the desk. The wood became slipprier, the squelches growing louder.
Manami knew she shouldn’t do something so dirty, so indecent, but she couldn’t help it. The thought of students using the desks for learning while she used them to cum was too much. But she was supposed to be a good girl, so she decided that she would only do this kind of thing on Fridays. She figured that if she did chemistry experiments on Mondays and Wednesdays, then her “good girl” points should balance out.
Manami slightly bent her knees and leaned forward, adjusting the angle. Her cunt clenched, her slick sliding and coating her clit. “Hah…♡ S-Sensei~♡”
She closed her eyes, imagining her home room teacher, Shiota Nagisa. She never considered herself a people-person, and she was scared of men in general. But Shiota-sensei was different. He was kind and he always listened to what she had to say. Sometimes he would stop by the chemistry lab and ask her about her experiments. He even let her have lunch in his office sometimes. She was so happy when she found out he was her third-year home room teacher.
She was sure Shiota-sensei would be so disappointed in her if he found out what she was doing at school. But the Shiota-sensei in her mind whispered sweet praises into her ear, bending her over the desk to play with her drooling pussy.
“O-Oh—!♡ Mmn…♡” Manami felt pressure building up. She rubbed her swollen clit harder against the desk, chasing her climax. “Ahn~~♡ S-Shiota-sensei—! ♡”
The classroom door opened with a clatter, jolting her in surprise before she could cum. Her heart stopped. There was a tall silhouette at the door.
“I thought I heard something. Turns out it was you, Okuda-san,” a smooth, velvety voice called out. The figure stepped into the classroom, sliding the door behind him.
“A-Akabane-sensei—!” Manami dropped her skirt and stood up straight, her underwear falling to the floor in the process. Her heart thumped loudly in her ears. “W-What are you…?
Her literature teacher, Akabane Karma, made smooth strides toward her, pulling up a chair and sitting in front of her. “I was doing final security rounds before closing up campus for the weekend.” Karma gave her a seemingly harmless smile, but the glint in his golden eyes didn’t quite match. “What are you doing here at school so late, Okuda-san?”
“I-I…” Manami tore her eyes away from his searing gaze, feeling faint. Literature was always her worst subject, and Akabane-sensei’s lecturing style didn’t help. He always wore a lazy smirk on his face, but was also strict when scolding her for her poor marks. It confused her, scared her.
Karma hummed when she hesitated to answer. “If you’re honest with me about what you were doing, I promise I won’t report you to the other teachers.”
She bit her lip, kneeling her knuckles as a self-soothing gesture. “I-I… I was… m-masturbating…” Her voice got softer and softer until the end of the sentence was just a whisper, but Karma still heard her.
“Hmm… I see.” His smirk broadened, teasing. “And whose name did you call out before I rudely interrupted you?”
“S-Shiota… sensei…” Hot tears of embarrassment pricked her eyes.
“Shh, don’t cry,” he cooed. “I’m sorry, I didn’t mean to make you cry.” He gently petted her head. “Thank you for being honest with me. I knew you were a good girl, Okuda-san.”
Manami wiped her tears with the back of her hand. “Y-You won’t tell…?”
“Of course not. It’ll be our little secret,” he reassured. “Why don’t you go ahead and show me the rest of what you were doing.”
Manami tensed, her heart skipping a beat. “W-Wha…?”
“You didn’t get to cum, right? I’m sure it’ll be hard for you to go home like that—“ Karma gestured to her juices dripping down her thighs, “—so why don’t you go ahead and continue with what you were doing.”
“I-I can’t… I mean…” a shudder ran through her. “Someone… someone might see…”
“All the students left hours ago, and all the faculty went home for the weekend, too,” he whispered the last part. “The only naughty kids left on campus are you and me, Okuda-san.”
Manami swallowed, her throat suddenly dry. “I-I…”
“If you show me, I promise I won’t tell anyone about this.” Karma leaned in closer until their noses were a few inches apart, his boyish grin widening when she tensed. He held a finger up to her lips, her breath coming out in short, warm pants. “Our little secret. Yea?”
Heat pooled in her lower abdomen, her slick dribbling down her thigh. Manami silently cursed her stupid body for reacting.
Tentatively, Manami straddled the corner of the desk again, lifting her skirt out of the way, so she could press her clit to the desk again. She started moving her hips, trying her best to hold back her voice. “…~♡”
Karma watched his student intently from the other side of the desk. He leaned forward on the chair. “Hmm… So that’s how you normally make yourself feel good.”
Her cheeks were hot with embarrassment, but she could feel and hear herself growing wetter by the second. She was sure Akabane-sensei could hear it, too. Her body felt like it was on fire, her mind rushing with adrenaline. Oh god, she was masturbating in front of her teacher. She squeezed her eyes shut, but still felt his searing gaze on her.
Her little pussy wanted more. Needed more. She rested her right hand on the desk, leaning against it for leverage as she applied more of her body weight on her clit. “Mmn…♡ hah♡… nyah~♡…”
“Your little clit is so swollen… You like being teased there?”
“Aah♡…mmng—♡” she nodded in between the jolts of pleasure, her voice failing her.
“How cute,” Karma praised. He leaned forward and rested his chin on his hand, his gaze shifting between her flushed face and her wet cunt peaking out from the hem of her skirt. “Do you like to finger that pretty little hole of yours?”
“I—nyahh~♡… don’ know—nng♡…inside—hah♡ s-scary♡”
“You’ve never touched yourself inside? What a waste.” His hand reached out, tilting her chin up to look at him. “I know you would look so pretty with something filling that perfect little cunt.”
His dirty praises went straight to her pussy. Manami pressed her hips against the desk harder and faster, the pleasure rising but not enough. She needed more. “Aah—♡ Sensei…♡ I-I can’t—mmn…♡” she whined.
He gave her an apologetic smile and cupped her cheek, almost as if pitying her. “Sorry, it must be hard to concentrate with someone watching you, right? How about I help you out, Okuda-san?”
“W-Wha—?”
Karma stood up from the chair and gently pulled her towards him, turning her to face him. He made room for himself between her legs, positioning her until she was leaning back and supporting her upper body with her arms on the desk. His large frame dwarfed her, caging her between him and the desk. He pushed up the hem of her skirt, exposing her bare cunt, still dripping. Manami grabbed his hand, hot embarrassment running through her. “W-Wait—!” she protested.
He brought her hand up to his lips, kissing her knuckles. “Shh…” he cooed. “I’ve got you, yea?” He gripped her hips and pressed her bare pussy against the large bulge in his trousers. Manami gasped, her cunt clenching against the hard outline of his cock. He began rocking her back and forth, grinding her weeping entrance on the soft fabric of his trousers.
The delicious friction sent waves of pleasure through her body, short-circuiting her brain. The sensation felt foreign, taboo. God, it was completely different from doing it herself. Karma held her hips in place, preventing her from moving the way she wanted to. The lack of control sent a shudder up her spine. Manami gripped the edge of the desk, a string of moans falling from her lips. “Ahn♡♡–!...Ngn–♡ A-Aka–ahn♡–! Sensei~~♡!”
The desk rattled beneath them as he continued grinding and thrusting against her weeping pussy. “Mmn… such a good girl. Hah… so wet…” he murmured, swiping his thumb against her clit. He didn’t even register the way her juices stained his trousers, focusing instead on his student, her eyes glassy and lips shiny with spit. “Who woulda thought… nng… prim and proper Okuda-san–hah… is actually a dirty slut?” he teased.
Manami’s face burned. “N-no–ahnn–♡! Mmn♡… o-oh♡…~~♡”
“No?” Karma’s grin widened. “Hmm? I think your pretty little cunt disagrees with you.” He tightened his grip on her hips, grinding her against him even harder as if to prove a point. “Hah… show me more.”
“S-Sensei~!♡♡ Ahng–♡~~” Hot pressure pooled in her abdomen, threatening to burst. “O-Oh♡! Akaba–ahnn~♡ Sensei~~♡! I-I’m gonna–♡♡!”
“You gonna cum?” Karma dipped his head close to her ears. “Go ahead and cum for me, Okuda-san.”
Like the obedient student she is, Manami came on his command, her body shuddering as her vision faded to white. Karma thrust against her convulsing cunt twice before stuttering to a halt with a rough grunt, holding her close against him. They rested against each other for a moment, Karma drawing little circles on her hips with his fingertips as their breaths evened.
Karma pulled away and straightened Manami’s glasses, which had shifted during their little session, before patting her head. “You good, Okuda-san?”
Still a little dazed, she gave a shy nod. He readjusted her skirt and picked up her forgotten panties from the floor, handing them to her. “What do you normally do after you cum?” he asked.
“I… just clean up and go home,” she replied, fidgeting with her braid. She reached into her bookbag and pulled out a packet of alcohol wipes and a packet of wet wipes.
“Well, aren’t you prepared,” Karma chuckled. “Do you also have spare clothes?” he asked, gesturing to her panties, wet with her arousal.
Manami shook her head. “My parents would find out…”
“I see,” he replied, sitting down on a chair. He pulled out a couple of tissues from his pocket and unbuckled his belt. Manami blushed when she saw a milky liquid and the tip of her teacher’s cock, still hard, peeking out from his briefs. She tore her eyes away, her cheeks growing hot again.
Karma chuckled. “After all that, don’t tell me you’ve never seen a man’s cock before?” he teased. “Cute.”
Manami bit her lip, her brows furrowing with confusion. “You’re… mean… Akabane-sensei…”
“I take that as a compliment.” He cleaned off his cum and readjusted his trousers. There wasn’t much he could do about the wet stain Manami left on him, but he was sure his winter coat would cover it. “Here, let’s clean you up.”
“I-I can do it myself,” she blushed.
“No need to feel embarrassed. I just made you cum, remember?” Karma lifted up the edge of her skirt. “Hold this.”
Manami did as she was told, squeezing her eyes shut as he wiped her slick off her inner thighs with a tissue. It was strangely intimate. His face was warm enough that his warm breath brushed across her thighs. His were much larger than hers, yet still gentle. She felt another wave of arousal wash over her and pool in her cunt.
“Okuda-san, you naughty girl,” Karma lightly chastised. “I’m trying to get you clean, so we can go home. Don’t make more work for me.”
“I-I’m sorry…” she blushed.
Karma hummed and placed a quick kiss on her thigh. “There. Your pretty little pussy is all clean.” He helped her put on her panties, and then they cleaned her slick off of the desk and the floor.
Manami gathered her belongings, ready to head home.
“Remember, this is our little secret, okay?” Karma reminded her.
She nodded.
“Also, I want you to come to my office next week after school. Same time as today.”
Manami’s face warmed. She gave another shy nod.
Our little secret…
