The late afternoon sun, a bruised plum hue, bled through the common room windows of U.A. High's Heights Alliance dorms. Most students were out, either training late, on internships, or simply enjoying the brief freedom before another arduous day of hero studies. But Yui Kodai, usually found meticulously arranging miniature objects or lost in the quiet depths of a textbook, was here. She sat curled in an armchair, a teacup held delicately in her hands, its warmth a small comfort against the subtle chill that seemed to seep into the very walls of the massive building as evening approached. Her thoughts, however, were anything but still.

A quiet sigh escaped her lips, almost imperceptible. Yui, known for her stoic demeanor and precise control over her Size quirk, often felt like an observer in the vibrant, boisterous world of her classmates. Yet, beneath that calm surface, a torrent of unspoken desires and burgeoning emotions swirled, particularly when certain individuals were near. The way her heart quickened, the flush that crept up her neck whenever a particular gaze lingered a moment too long, betrayed the carefully constructed composure she maintained.

The soft click of the common room door broke her reverie. Yui's eyes, usually a placid gray, darted up, and a subtle tremor ran through her. It was him. He entered, a faint scent of ozone and sweat clinging to him from a late training session, his presence immediately filling the expansive room. He paused, his gaze meeting hers across the space, and in that fleeting moment, the world outside their shared bubble seemed to melt away. A shy, almost imperceptible smile touched his lips, and Yui felt her own lips curve in response, a rare, genuine expression of warmth that few were privy to.

He moved towards her, his steps deliberate, his eyes never leaving hers. "Kodai," he rumbled, his voice a low thrum that vibrated through the air, and, inexplicably, through her very core. "Still up? I thought everyone had turned in."

"Just... enjoying the quiet," Yui replied, her voice soft, a whisper that barely carried across the growing intimacy of the space between them. She felt a blush creep up her cheeks, betraying her usual composure. As he drew closer, she became acutely aware of her own body, the way her uniform skirt clung to her thighs, the gentle swell of her chest beneath her blouse. She had always been self-conscious about her figure, the noticeable curve of her hips, the fullness of her breasts, often shrinking from attention. But tonight, under his gaze, she felt a strange mix of vulnerability and burgeoning confidence.

He settled into the armchair opposite her, leaning forward slightly, his elbows resting on his knees. "Training was brutal today," he admitted, running a hand through his hair. "I think Cementoss is trying to break us." A shared laugh, light and easy, filled the space. But then the laughter faded, replaced by a comfortable silence, punctuated only by the distant hum of the dorms. His eyes, dark and intense, drifted over her, lingering for a fraction of a second longer on the subtle contours of her figure, on the gentle rise of her chest as she breathed, and then, unmistakably, on the soft curve of her lips.

Yui's heart hammered against her ribs, a frantic bird trapped within her chest. She found herself unable to look away, caught in the magnetic pull of his presence. She saw a flicker of something raw and yearning in his eyes, a reflection of her own burgeoning desires. The air thickened, heavy with unspoken words and tantalizing possibilities. The teacup, forgotten, began to cool in her hand. Her fingers twitched, a desperate urge to reach out, to bridge the small, yet vast, distance separating them.

"You... you look tired," she finally managed, the words barely a breath. Her gaze was drawn to the strong line of his jaw, the subtle flex of muscles in his neck. This was a man of power, of unwavering resolve, a hero in training from Boku No Hero Academia, just like her. But in this moment, he was simply a man, and she, a woman, caught in a shared, electric current.

He chuckled softly, a low, husky sound that sent a shiver down her spine. "Maybe a little. But seeing you here... it's a good kind of tired, I guess." His words, so simple, yet so loaded, sent a jolt through her. Yui felt her entire body hum with a nervous energy. The tension, palpable and exquisite, stretched between them like an invisible thread, tightening with every shared glance, every lingering moment.

Slowly, deliberately, he reached out, his hand extending across the space. Yui watched, mesmerized, as his fingers brushed against hers, a feather-light touch that nonetheless ignited a searing heat wherever it made contact. Her skin tingled, alive with an almost painful awareness. His thumb began to gently caress the back of her hand, a slow, hypnotic movement that stole her breath away. Her grip on the teacup loosened, and it clattered softly onto the small table beside her, forgotten. Her entire focus narrowed, honing in on that singular, tender touch.

"Yui," he whispered, her name on his lips a revelation, a soft plea. He leaned in further, his scent, now closer, a heady mix of clean sweat and something uniquely masculine. Her eyes fluttered closed for a moment, savoring the intimacy of it, the delicious anticipation. When she opened them, his face was inches from hers, his gaze burning into her. Her body yearned forward, an instinctual pull she couldn't deny.

And then, his lips were on hers. It was a tentative beginning, a soft exploration, a question rather than a demand. Yui responded instantly, her own lips parting to welcome him, her unspoken desires finally unleashed. The kiss deepened, becoming more fervent, more hungry. His hand slid from hers, moving up her arm, over her shoulder, tangling in the soft strands of her hair at the nape of her neck. He pulled her closer, the chairs separating them suddenly an unbearable barrier.

With a desperate surge of energy, Yui pushed herself up from her armchair, practically falling into his lap. Her arms instinctively wrapped around his neck, holding him close as the kiss intensified, becoming a breathless symphony of longing. She felt the solid muscle of his thighs beneath her, the warmth of his body radiating through her clothes. His other hand found its way to her waist, pulling her flush against him, allowing her to feel the undeniable hardness that pressed against her lower belly.

A soft moan escaped her throat, a sound she didn't even recognize as her own. She broke the kiss for a moment, gasping for air, her forehead resting against his. "I... I've wanted this," she confessed, her voice thick with emotion, raw and vulnerable. "For so long."

"Me too, Yui," he breathed, his voice hoarse with desire. His lips moved from hers, trailing down her jawline, across her sensitive neck, sending shivers through her entire frame. His touch was igniting a fire within her, melting away her usual reserve, transforming her into a creature of pure sensation. His hand, no longer content with her waist, began to explore. It moved slowly, deliberately, tracing the curve of her spine, then dipping lower, towards the generous swell of her *Big Ass* beneath her uniform skirt. He squeezed gently, possessively, and Yui arched into the touch, a whimper escaping her.

Her skirt felt suddenly too tight, too restrictive. His fingers slid under the hem, brushing against the smooth skin of her thigh, sending a jolt of pure pleasure through her. "Let's go somewhere more private," she whispered urgently, her eyes wide with a mixture of desire and a lingering shyness. The common room, once a haven of quiet intimacy, now felt too exposed, too open for the raging storm within them.

He nodded, a silent agreement. Gently, he lifted her from his lap, and they moved as one, a silent, urgent procession to her dorm room. The walk was a blur, their hands intertwined, a silent promise hanging in the air. Once inside, the door clicked shut behind them, sealing them off from the rest of the world, creating their own sanctuary of burgeoning passion.

Her room was neat, organized, a reflection of her personality. But tonight, that order was about to be delightfully disrupted. He pulled her back into his arms, his mouth claiming hers once more, deeper, more demanding than before. His hands were everywhere now, caressing, exploring, igniting every nerve ending. He worked the buttons of her blouse with surprising dexterity, his fingers brushing against the soft skin of her chest as each button came undone. Yui, in turn, fumbled with the clasp of his belt, her fingers trembling with a desperate urgency.

The blouse fell open, revealing a simple, white bra that did little to contain the generous fullness of her *Big Tits*. He gasped, a low, guttural sound of appreciation, his eyes darkening with hunger. "You're... incredible, Yui," he murmured, his voice thick with emotion, his gaze fixed on her chest. Her nipples, already firm and aching, pressed against the lace, begging for release. A fresh wave of heat washed over her, and Yui felt her core clench in anticipation.

His hands reached for the straps of her bra, easing them down her shoulders. Then, with a slow, agonizing pull, he liberated her breasts, allowing them to spill forth, full and heavy. Yui felt a blush spread across her face, but it was not shame, it was pure, unadulterated desire. She watched his eyes, saw the raw hunger in them, and felt a thrill course through her. He leaned down, his tongue flicking out to tease one prominent nipple, sending an electric shock through her entire body. She cried out softly, her fingers digging into his shoulders.

He suckled, drawing her deeper into his mouth, his tongue swirling around the sensitive peak. Yui's knees threatened to buckle, and she gripped him tighter, her head thrown back, a helpless moan escaping her lips. The exquisite pleasure was almost unbearable, a sweet agony that made her arch her back, offering herself more fully to his ministrations. He alternated between her breasts, teasing, licking, sucking, driving her to the brink of madness.

While one hand continued its delicious assault on her breasts, the other moved lower, pushing aside the fabric of her skirt and panties. His fingers, warm and knowing, found the dampness between her legs. Yui gasped, her body jerking in surprise and delight. He stroked her gently, his thumb finding her clitoris, teasing it with light, circular motions. Her body, already trembling, began to convulse with building pleasure. "Oh, god," she whimpered, her voice barely audible, lost in the maelstrom of sensation. This was Yui Kodai, the quiet, composed hero in training from My Hero Academia, completely undone.

He lifted her again, easing her onto the edge of her bed, her legs dangling, still dressed in her skirt, but her lower body now exposed. He knelt before her, his eyes blazing, and carefully, reverently, peeled off her uniform skirt, then her panties. The sight of her naked, trembling femininity, her *Big Ass* curving invitingly as she sat, seemed to mesmerize him. He lowered his head, his tongue tracing a path along her inner thigh, making her shiver uncontrollably.

Yui gasped, her fingers tangling in his hair, pulling him closer. He was going to taste her, truly taste her, and the thought alone sent waves of liquid heat through her. His mouth descended, hot and wet, engulfing her clitoris, sending a shockwave of pleasure directly to her core. She cried out, her body arching off the bed, her hips bucking instinctively. He devoured her, his tongue working magic, swirling, flicking, sucking, driving her higher and higher. Each stroke was an exquisite torment, building to an unbearable crescendo. Her legs trembled, splayed wide as she surrendered completely to the mind-numbing pleasure.

"Please... please," she begged, though for what, she wasn't sure. More, less, she just knew she couldn't take much more, but desperately wanted to. A wave of intense pleasure washed over her, her body stiffening, her breath catching in her throat, as she climaxed for the first time, a sweet, shattering release that left her weak and gasping. He continued to tease her for a moment longer, savoring her shivers, before finally pulling away, his face slick with her essence, a triumphant grin on his lips.

He rose, stripping off his own clothes with practiced ease, revealing a powerful, muscular physique that made Yui's breath catch in her throat all over again. Her eyes devoured him, tracing the lines of his chest, his strong arms, and then, inevitably, drawn to the hard shaft that stood proudly, throbbing with anticipation. He was magnificent, a true hero in every sense of the word, and he was here, with her, wanting her as desperately as she wanted him.

He joined her on the bed, pulling her close, kissing her deeply, tasting himself on her lips. "Ready for me, Yui?" he whispered against her mouth, his voice raw with desire. She nodded, unable to speak, her eyes wide with a hungry anticipation. He positioned himself between her legs, his hard shaft pressing against her entrance, slick and ready. Yui felt a thrill of nervous excitement and intense longing course through her. This was it. The moment she had unconsciously yearned for.

He entered her slowly, carefully, allowing her body time to adjust to his impressive size. Yui gasped, a sharp intake of breath as she felt the exquisite stretch, the fullness that spread through her. Her eyes squeezed shut, tears of pleasure welling at the corners. "Oh, god," she whispered, her voice choked with emotion. He pushed deeper, inch by agonizing inch, until he was fully buried inside her, a perfect, exquisite fit. She wrapped her legs around his waist, pulling him even closer, wanting to feel every inch of him.

He paused, allowing her to acclimate, their bodies pressed flush against each other, their chests heaving in unison. Then, slowly, he began to move, a gentle, deliberate rhythm that quickly escalated into a powerful, passionate thrust. Yui met his every movement, her hips rising to meet his, lost in the intoxicating rhythm of their bodies joining. Each thrust was a stroke of pure ecstasy, filling her, stretching her, eliciting soft cries and breathless moans from her lips.

His hands found her *Big Ass*, cupping the soft, firm mounds, squeezing them possessively as he drove into her. Yui arched her back, her full breasts bouncing with each powerful thrust, her nipples brushing against his chest, sending fresh waves of sensation through her. The bedsprings creaked a gentle protest, but they were too far gone to care, lost in the primal dance of their bodies. The scent of their mingled arousal filled the room, a potent aphrodisiac.

"Faster," Yui pleaded, her voice hoarse, her body trembling on the verge of another orgasm. "Please, faster!"

He obliged, increasing the tempo, his thrusts becoming deeper, more urgent, slamming into her with a delicious force that made her cry out his name. Her internal walls gripped him tightly, milking him with every movement, intensifying the pleasure for them both. The world narrowed to the sensations, the rhythm, the sound of their skin slapping together, her increasingly frantic moans, and his own guttural groans of pleasure. This was pure, unadulterated passion, a physical manifestation of the unspoken desires that had simmered between them for so long within the confines of Boku No Hero Academia.

Yui felt the familiar tightening deep within her, the building pressure, the sweet, agonizing rush that signaled another climax. Her body stiffened, her hips bucked uncontrollably, and she cried out, a long, drawn-out moan as her orgasm shattered through her, sending spasms of intense pleasure rippling through her entire being. She squeezed him tightly, her release milking him, driving him to his own brink.

He thrust into her one last time, deeper than ever before, a guttural roar escaping his lips as he too found his release, emptying himself deep inside her. Yui felt the hot, pulsing rush of his essence filling her, a sensation both shocking and incredibly intimate. The warmth spread through her, a delicious, heavy feeling that settled deep in her womb. A *creampie*, a tender, undeniable mark of their profound intimacy, sealing their bond in the most primal way possible. They lay there for a moment, entwined, breathless, the aftershocks of their shared climax still rippling through their bodies.

Slowly, he withdrew, his body still heavy with the lingering passion, leaving her feeling full and deliciously satisfied. He collapsed beside her, pulling her close, wrapping his arms around her, their skin slick with sweat, their breaths still ragged. Yui snuggled into his side, her head resting on his chest, listening to the powerful beat of his heart. She felt utterly cherished, completely adored, and wonderfully complete.

"That was... incredible," she whispered, her voice hoarse, her fingers tracing patterns on his chest. A soft, contented sigh escaped her lips. The quiet girl from Boku No Hero Academia, the one who often faded into the background, had just experienced something profoundly transformative, something that had cracked open her carefully constructed shell and revealed a depth of passion she never knew she possessed.

He kissed the top of her head, his lips lingering. "You are incredible, Yui Kodai," he corrected gently, his voice thick with emotion. "Every single part of you." His hand moved to her stomach, gently caressing the soft skin, a silent acknowledgment of the life-affirming warmth still residing within her. The quiet of the dorm room settled around them once more, but this time, it was not empty. It was filled with the lingering echoes of their passion, the sweet scent of their lovemaking, and the quiet promise of a future where unspoken desires would always find their beautiful, explosive release.
