The late afternoon sun, a soft, honeyed glow, filtered through the dusty blinds of the deserted classroom, painting stripes of warmth across the polished wooden floor. Lee Saim, usually a whirlwind of nervous energy and quiet contemplation, found herself lingering. The air was thick with the scent of old paper, chalk dust, and something else… something akin to anticipation, a subtle perfume that clung to the silence. Her heart, a skittish bird, fluttered against her ribs. She adjusted the frame of her glasses, the cool plastic a familiar comfort against her skin, and glanced towards the teacher's desk. Professor Kang, his usual calm demeanor radiating a quiet authority, was packing away his lecture notes, the rhythmic rustle of paper a soothing counterpoint to the growing thrum in her veins.

She was supposed to have left hours ago, along with the last of her classmates, but a forgotten textbook, a meticulously studied one at that, had provided the perfect, albeit fabricated, excuse. Now, the pretense felt flimsy, almost transparent, under the weight of her unspoken desires. Professor Kang was everything a student admired, and for Lee Saim, he was the unattainable star she orbited. His intellect, his kindness, the way his brow furrowed in concentration when he explained complex theories – it all combined to create an aura of profound allure. And then there were his eyes, deep and observant, that seemed to see more than just the diligent student before him. They saw… her. Or at least, that's what her hopeful heart whispered.

He turned, a gentle smile gracing his lips as he noticed her still there. "Lee Saim? Still here?" His voice was a low, resonant baritone that sent a shiver down her spine. "Did you find that book?"

She nodded, her throat suddenly tight. "Yes, Professor. I found it." She held up the worn volume, her hand trembling almost imperceptibly. Her gaze, however, remained fixed on him, tracing the subtle curve of his jaw, the slight stubble that hinted at a long day, and the way his shirt collar was just a fraction too loose, revealing the firm line of his throat. It was a dangerous fascination, a secret she nurtured in the quiet corners of her mind, the kind that bloomed like forbidden flowers in the fertile soil of her youth. He was her designated bully, a title whispered in hushed tones by the school gossip mill, a narrative she both chafed against and, in her secret heart, found a strange, perverse thrill in challenging.

Professor Kang’s smile widened, a warmth radiating from him that seemed to chase away the last vestiges of the day’s chill. "Good. I'm glad you found it. You're always so dedicated to your studies, Lee Saim." He walked towards her, and with each step, the space between them seemed to shrink, crackling with an unseen energy. He stopped just a few feet away, his proximity sending a wave of heat through her. She could smell his cologne, a subtle blend of sandalwood and something undeniably masculine, a scent that promised both comfort and a hint of wildness.

Her mind raced, a chaotic jumble of anxieties and burgeoning hopes. This was it. This was the precipice. The silence stretched, amplified by the beating of her own heart. He reached out, his fingers brushing against the cover of her textbook, a feather-light touch that ignited a firestorm within her. "You know," he began, his voice dropping to a softer register, "sometimes, dedication can lead to… unexpected discoveries." His gaze held hers, and in their depths, she saw not just her professor, but a man, a man whose quiet intensity had been subtly captivating her for months.

Her cheeks flushed, a deep crimson that she knew was entirely betraying her inner turmoil. She swallowed, trying to find her voice. "Discoveries, Professor?" she managed, her voice a breathy whisper. The tag, "teacher," swam in her mind, a forbidden word that held a potent allure. She was aware of the societal boundaries, the unspoken rules, but in this private space, with the sun setting and the school empty, those lines felt blurred, yielding to a raw, undeniable attraction.

He chuckled, a low, rumbling sound that vibrated through her. "Yes. Discoveries about oneself. About what one is truly capable of." He let his gaze drift, a slow, appreciative sweep that lingered on her figure. Lee Saim was acutely aware of her own body, a fact that usually made her shy and self-conscious, but under his gaze, a different sensation began to bloom. A newfound confidence, a sense of being seen, truly seen, for the first time. She knew she wasn't conventionally the most voluptuous girl in school, but she had a certain grace, a subtle sensuality that was often overlooked. The slight curve of her hips beneath her school uniform, the gentle swell of her breasts pressing against the fabric of her blouse – these were details she usually tried to conceal, but now, they felt… noticed.

He leaned closer, his breath fanning her cheek. "Lee Saim," he said, his voice laced with a new intimacy, "you have a certain… fire. I've seen it in your eyes during lectures, in the way you tackle difficult questions. It's a beautiful thing." His words were a balm to her insecurities, a potent elixir that dissolved her nervousness into pure, unadulterated yearning. He spoke of her "designated bully" persona, not as a flaw, but as a hidden strength, a resilience that intrigued him. It was a perspective she'd never considered, and it sent a jolt of excitement through her.

Her hands, which had been clasped tightly in front of her, began to relax. She dared to meet his gaze directly, her heart pounding a frantic rhythm against her ribs. "You… you see that?" she asked, her voice barely audible. The air between them thrummed with an unspoken question, a delicate dance of attraction and apprehension. She imagined the softness of his skin, the strength of his arms, the taste of his lips, and a blush, even deeper than before, spread across her face. The tag "Big Tits" felt a sudden, electrifying awareness within her, a burgeoning confidence in her own physical form, amplified by his subtle appreciation.

Professor Kang’s eyes darkened, a spark igniting within their depths. He reached out again, this time his fingers gently cupping her cheek, his thumb stroking the soft skin of her jawline. "I see more than you know, Lee Saim." His touch was electric, sending tremors of pleasure through her entire body. She closed her eyes for a brief moment, savoring the sensation, the warmth of his hand against her skin. When she opened them again, his face was closer, his gaze intense, filled with a desire that mirrored her own. The romantic tension had reached a fever pitch, a delicate thread stretched taut, ready to snap.

He lowered his head, his lips brushing against hers, a tentative, exploratory kiss that sent fireworks through her veins. It was soft at first, a gentle seeking, but as she responded, a tentative sigh escaping her lips, the kiss deepened. His arms, strong and firm, wrapped around her waist, pulling her closer, her body molding against his. Her hands, emboldened by his touch, found their way to his chest, feeling the steady beat of his heart beneath the fabric of his shirt. The scent of him, the warmth of his body, the intoxicating taste of his lips – it was a symphony of sensations that overwhelmed her senses.

The textbook slipped from her grasp, falling to the floor with a soft thud, an unimportant casualty in the face of this burgeoning passion. The classroom, once a place of academic pursuit, had transformed into a sanctuary of shared desire. He pulled back slightly, his forehead resting against hers, their breaths mingling. "Lee Saim," he whispered, his voice husky, "I shouldn't…" But the unspoken words hung in the air, charged with the knowledge that they both knew he would. The "teacher" tag, once a barrier, now seemed to be an exhilarating part of the forbidden thrill.

She leaned into him, her lips finding his again, this time with a hunger that surprised even herself. The kiss was no longer tentative; it was a declaration, a surrender. His hands moved, sliding up her back, then under her blouse, his touch sending shivers of delight through her. His fingers brushed against the soft lace of her bra, a teasing caress that made her gasp. She could feel the heat radiating from his touch, a tangible promise of what was to come. The "Big Tits" tag, once a source of shy awareness, was now a focal point of his attention, and a burgeoning sense of pride swelled within her.

He unbuttoned her blouse slowly, deliberately, his eyes never leaving hers, savoring the unveiling. Each button was a step further into their shared secret. The fabric parted, revealing the swell of her breasts, the delicate curve of her collarbone. He traced the line of her clavicle with his lips, his touch both reverent and possessive. She arched into him, her fingers tangling in his hair, pulling him closer. The world outside, with its rules and expectations, ceased to exist. There was only this moment, this overwhelming intimacy.

His hands cupped her breasts, his thumbs teasing her nipples through the lace. She cried out, a soft moan of pleasure, her body arching against his. He eased the strap of her bra down, then the other, exposing her fully to his gaze. He looked at her with an intensity that made her tremble, a mixture of admiration and pure, raw desire. "Beautiful," he whispered, his voice rough with emotion. He lowered his head, his lips finding the swell of her breast, his tongue teasing her nipple until it hardened under his ministrations. Lee Saim gasped, her fingers digging into his shoulders as waves of pleasure washed over her.

He continued his exploration, his mouth moving to her other breast, his touch sending her spiraling. She felt her skirt being pushed up, her thighs exposed to the cool air, then to the warmth of his hands. He caressed her, his touch sending shivers of anticipation through her. She was acutely aware of her "Big Ass," usually a source of self-consciousness, but now, it felt like a point of exquisite focus for his attention. He squeezed gently, his touch sending a jolt of pleasure through her. The romantic tension had dissolved into pure, unadulterated lust, a primal force that consumed them both.

He knelt before her, his eyes still locked on hers, a silent question in their depths. She nodded, a silent consent that spoke volumes. He unzipped her skirt, the sound a soft rasp in the quiet room. Her underwear was quickly dispatched, leaving her bare before him. He looked at her, his gaze devouring every inch of her, his appreciation evident. Lee Saim felt a surge of confidence, a boldness she'd never known. She reached down, her fingers finding his belt, then the button of his trousers. The tag "Manhwa" seemed to be manifesting around them, a dramatic, sensual tableau unfolding in the dimming light.

He rose to his feet, his arousal evident, pressing against her. He guided her to the edge of the desk, her legs parting instinctively. He then pushed her skirt up further, revealing the wetness between her thighs. He knelt again, his fingers delicately parting her lips, his tongue finding her clitoris. Lee Saim gasped, her hands flying to her hair as she surrendered to the exquisite pleasure. Her moans echoed softly in the quiet classroom, a testament to the intensity of her arousal. He teased and tasted, his tongue a masterful instrument, eliciting gasps and cries of pleasure from her.

Her whole body trembled, her senses heightened to an almost unbearable degree. She was on the brink, her mind dissolving into pure sensation. With a final, lingering stroke, he brought her to a shattering climax, her body convulsing, her cries rising in intensity. He held her close, letting her catch her breath, his fingers still caressing her damp flesh. The relief was profound, a deep, satisfying release that left her weak and breathless.

He then stood, pulling her up to face him. His gaze was still intense, his desire evident. "Now, my dear Lee Saim," he whispered, his voice husky with passion, "it is my turn." He unbuckled his belt, his movements deliberate. His trousers slid down, revealing his thick, hard cock. Lee Saim’s breath hitched. It was magnificent, a testament to his desire for her. She reached out, her fingers tracing the head of his phallus, her touch sending a shiver through him. She felt a surge of possessiveness, a desire to claim him, to experience him fully.

He gently guided her to sit back down on the desk, her legs parting again. He positioned himself between her thighs, his cock nudging against her entrance. She moaned, her body eager to receive him. He pushed in slowly, filling her with his length. Lee Saim gasped, her eyes closing as she embraced the sensation. He was so big, so full, and she felt herself gripping him tightly, her body welcoming him. The "Creampie" tag flashed in her mind, a promise of the intimacy to come, a desire to be completely filled, completely taken.

He began to move, his thrusts deep and powerful. Each stroke sent waves of pleasure through her, a primal rhythm that echoed in the silent classroom. Her moans became louder, more insistent, mingling with his own guttural groans. Her hands were on his back, her nails digging into his skin as she met his every thrust. She could feel the slickness between them, the friction building, the heat intensifying with each movement. Her "Big Ass" arched against his hips, seeking deeper penetration, her body craving the fullness he offered. The "Manhwa" feel was becoming intensely real, a passionate, raw depiction of their mutual desire.

He picked up the pace, his thrusts becoming faster, more urgent. Lee Saim was lost in the sensation, her mind a blur of pleasure. She felt herself nearing another climax, her body tensing in anticipation. His strokes grew deeper, more relentless, and with a final, powerful push, he brought her to the edge once more. She cried out his name, her body arching violently as she came, waves of intense pleasure washing over her. He followed soon after, his body tensing, his thrusts becoming wilder as he poured himself into her. Lee Saim felt his warm load flood her, a deep, satisfying sensation that left her breathless and utterly sated. The tag "Creampie" was now a reality, a profound intimacy shared.

They stayed like that for a long moment, intertwined, their bodies slick with sweat, their breaths coming in ragged gasps. The silence that followed was not awkward, but filled with a profound sense of connection, a shared intimacy that transcended the boundaries they had crossed. Professor Kang gently pulled out, his cock still heavy and glistening. He looked at her, his eyes filled with a mixture of tenderness and a deep satisfaction. Lee Saim returned his gaze, a soft smile gracing her lips. The forbidden allure of the "teacher" had led to a passionate, unforgettable encounter. Her "designated bully" status seemed to have faded into insignificance, replaced by a newfound confidence and a deep, heartfelt connection.

He gently kissed her forehead, then her lips, a soft, lingering kiss that spoke of more than just physical pleasure. "Lee Saim," he whispered, his voice still rough with emotion, "that was… extraordinary." He helped her adjust her skirt, his touch lingering on her thigh. She felt a blush creep back onto her cheeks, not of embarrassment, but of a shy pleasure. The "Big Tits" and "Big Ass" tags were no longer sources of insecurity, but parts of a whole that had been celebrated and desired.

As they slowly dressed, a comfortable silence settled between them. The sun had long since set, and the classroom was now bathed in the soft glow of the hallway lights. The air was still charged, but now with a gentle warmth, a shared secret that bound them together. Lee Saim knew that this was not just a fleeting encounter; it was the beginning of something profound, a connection forged in passion and mutual respect. The romantic tension had culminated in an explicit encounter, but the resolution was one of tenderness and a deep, unspoken understanding. She gathered her textbook from the floor, her heart full, a quiet joy settling within her as she looked at Professor Kang, the "teacher" who had become so much more.
