CHAPTER 50: CHAPTER 50: THE FIRST FLAME

Rika sat alone at her desk after school, the classroom bathed in the orange wash of sunset. Her pen tapped against a half-marked paper, though she hadn’t read a single word in minutes. Her thoughts had been hijacked....again....by one person.

Renji Sakamoto.

Her student. Her savior. Her... temptation.

She exhaled, closing her eyes. Damn it... why am I like this?

Ever since he walked into her life, he had turned her carefully ordered world upside down. At first, she had resisted, pushing back, insisting on boundaries. But boundaries had melted away with every kiss, every caress, every night he made her feel alive again.

Yet lately... she had noticed something unsettling. His charm wasn’t hers alone anymore. The nurse, Reina, looked at him differently now. Rika wasn’t stupid—she’d seen the way Reina smiled when Renji passed by, seen how her hand lingered on his shoulder just a second too long.

And Renji himself? He hadn’t said anything, but he didn’t have to. She could feel the shift. That magnetic presence of his wasn’t focused solely on her anymore.

A pang of jealousy struck her chest. She hated the feeling—it made her feel childish, insecure. She was the adult, the teacher, the woman who was supposed to have control. But around Renji... she was anything but in control.

The classroom door creaked open.

Her heart skipped.

"Sensei," his voice came, smooth and calm, yet brimming with mischief. "Still working?"

Rika straightened, quickly adjusting her glasses as if to hide her fluster. "Renji, you shouldn’t be here. School hours are over."

He leaned casually against the doorframe, his tie loose, his shirt unbuttoned at the top, revealing a glimpse of his chest. "And yet, here you are. Alone. Waiting for me."

Her cheeks burned. "Don’t be ridiculous. I’m grading papers."

"Mm. Must be hard to focus when your mind is elsewhere." He stepped closer, his smirk deepening as he watched her eyes widen.

Rika’s pen froze in her grip. She wanted to deny it. She wanted to tell him off, to send him away, to remind him of the risks they took every time they were together.

But instead, she whispered, "And where exactly do you think my mind is, Sakamoto-kun?"

His answer was immediate, bold, cutting straight to her heart.

"On me."

The silence between them sizzled. Her chest rose and fell faster, the jealousy, the longing, the hunger she had been burying all rushing to the surface.

She hated how right he was. And she hated even more how badly she wanted him to prove it.

Renji closed the distance until he stood right beside her desk, looking down at her with that confident gleam in his eyes, the look that said he knew he already owned her.

Rika’s grip on the pen trembled as Renji leaned closer, his presence filling the small space around her desk. His scent....clean soap with a faint undertone of boyish sweat wrapped around her, invading her senses.

She tried to steady herself, her voice a whisper. "Renji... this is dangerous. Someone could walk in."

He tilted his head, smirking. "The only danger here is you lying to yourself, sensei."

Before she could retort, his hand slid down, brushing lightly against her wrist. The contact sent a jolt straight to her stomach. Rika’s body betrayed her instantly—heat pooling between her thighs, nipples tightening under her blouse.

"Y-you’re insufferable," she muttered, pushing weakly at his chest.

He caught her hand, guiding it instead to his shirt. "Then why don’t you stop me?"

Rika swallowed, her pulse hammering. She should stop him. Every rational thought told her this was wrong. She was his teacher, his elder, the adult here. But staring up into his dark, commanding eyes, she felt like anything but.

Her lips parted. No sound came out.

Renji chuckled low in his throat, leaning down until his mouth brushed against her ear. "You’re jealous, aren’t you, sensei?"

Her whole body stiffened. "W-what?"

He pulled back just enough to see her expression, his grin widening as her blush deepened. "You saw Reina looking at me. You’ve been thinking about it, haven’t you? About me touching her the way I touch you."

Rika’s chest heaved. She wanted to deny it, but her voice cracked when she tried. "You... you arrogant brat..."

His hand slipped under her desk, onto her thigh. Rika gasped, her legs clamping instinctively, but he pressed firmly, parting them just slightly.

"I like it," he whispered, his thumb stroking slow circles against her stocking. "That fire in your eyes. That possessiveness. Makes me want to remind you, sensei..."

His fingers trailed higher, brushing dangerously close to her heat.

"...that you’re mine."

Her breath caught, every nerve ending alive, trembling. "Renji..."

He leaned down, kissing her hard before she could say another word. It wasn’t gentle. It wasn’t patient. It was claiming, hungry, devouring. Rika moaned into his mouth, clutching at his shirt as her resistance crumbled.

Her jealousy burned away, replaced by something fiercer....desire, need, the desperate urge to feel every part of him and to make sure he felt every part of her.

When he finally pulled back, a thin line of saliva connected their lips. His eyes locked with hers, daring her to deny him again.

Rika’s voice came out hoarse, needy. "Lock the door."

Renji’s grin widened. Without a word, he turned, strode to the classroom door, and twisted the lock. The click echoed like a gunshot in the quiet room.

When he faced her again, his tie was already coming off.

The sound of the lock clicking still reverberated in Rika’s chest. Her whole body felt tense, caught between panic and wild anticipation.

Renji walked back toward her, unhurried, his tie dangling loosely in his hand. His gaze never left hers, dark and hungry.

"R-Renji..." she stammered, standing from her chair as if to put distance between them. But the moment she rose, her back met the edge of the desk. She was trapped.

He smirked, tossing his tie aside before placing his palms on either side of her, caging her in. "You told me to lock it, sensei. No backing out now."

Her lips trembled. "I should stop this... but I..."

"Don’t lie to me," he murmured, his hand rising to cup her cheek. His thumb brushed across her lower lip, teasing it down until her mouth parted. "Your eyes say everything. You’ve been mine since the first night."

Her knees weakened, her body screaming for him even as her pride tried to fight back. "Renji... you make me feel like a student again..."

He leaned in, his lips ghosting against hers. "Good. Then let me be your teacher tonight."

Before she could catch her breath, his mouth crashed onto hers. The kiss was deeper this time, his tongue forcing past her lips, claiming her fully. Rika moaned against him, her hands fisting in his shirt, tugging him closer as if to punish herself for hesitating.

Renji’s hands were relentless—one gripping her hip, pulling her flush against him, the other sliding upward, finding the curve of her breast through the thin fabric of her blouse. His thumb pressed against her hardened nipple, and she gasped into his mouth, breaking the kiss.

"Renji!" she whispered, voice thick with desire and fear. "The school

....if anyone—"

"They won’t." His tone was firm, commanding, his lips brushing along her neck. "Right now, it’s just us."

His teeth grazed her collarbone, and she arched, her nails digging into his back. She was melting, trembling, caught between duty and the fire consuming her.

Her blouse loosened as he undid the first button, then another, his fingers working swiftly. Her chest heaved, each undone button a death knell to her resistance. By the time her blouse hung open, exposing the black lace bra she swore she’d only worn to boost her own confidence, her breath was ragged.

Renji pulled back just enough to drink her in. His smirk was wicked. "So the strict sensei wears lace? You’ve been waiting for this, haven’t you?"

"Shut up..." she whispered, face burning, but her trembling hands betrayed her as they tugged at his shirt, desperate to feel his skin.

He caught her wrists, pinning them above her head against the chalkboard behind the desk. She gasped, her body pressed between the cool board and his heat.

"Say it," he demanded, his voice low and dangerous. "Say you want me."

Rika squeezed her eyes shut, shaking her head as if she could still deny him. But his thigh pressed between hers, grinding against her heat, and the sensation ripped a moan from her lips.

Her eyes shot open, glassy with lust. "I... I want you."

Renji grinned, triumphant, before kissing her hard enough to steal the air from her lungs.

Rika’s whispered confession still hung in the air, trembling like a fragile string ready to snap.

"I want you..."

Renji’s lips curved into a slow, dangerous smile. That was all he needed. His grip tightened on her wrists, pressing them harder against the chalkboard as his knee parted her thighs even wider.

"Say it again," he ordered.

Her chest rose and fell, eyes wide with both terror and hunger. "I... I want you, Renji."

"That’s better."

He released her hands only to tug her blouse fully open, exposing her lace-covered breasts. Her nipples strained against the fabric, hard and aching, and when his mouth closed over one, biting through the lace, Rika nearly screamed.

"Renji—ahhh!" Her voice broke, echoing in the empty classroom.

His hand trailed down her stomach, fingers finding the waistband of her skirt. With one tug, he yanked it up, bunching the fabric at her waist. Her stockings clung to her thighs, but her panties were soaked, the fabric clinging obscenely to her slit.

"You’re dripping for me, sensei," he teased, rubbing a thumb over the damp spot. "So much for being the strict teacher."

"Shut up..." she hissed, hiding her face against his shoulder. But when he pressed harder, her hips bucked shamelessly against his hand.

Renji chuckled darkly. "I’ll make you scream my name loud enough for the whole school to hear if you keep acting shy."

Her nails dug into his shoulders. "Please... don’t tease me anymore."

Shut up..." she hissed, hiding her face against his shoulder. But when he pressed harder, her hips bucked shamelessly against his hand.

Renji chuckled darkly. "I’ll make you scream my name loud enough for the whole school to hear if you keep acting shy."

Her nails dug into his shoulders. "Please... don’t tease me anymore."

He didn’t answer with words. Instead, he hooked his fingers into her panties and pulled them down in one swift motion, letting them fall around her ankles. The cool air hit her soaked pussy, making her shiver.

Renji’s cock strained against his pants, and he freed himself in seconds, his thick length springing free. Rika’s eyes widened when she saw it—her lips parted as if she couldn’t quite believe the size.

"Renji..."

He grabbed her chin, forcing her gaze back to his. "You asked for this. No running."

Then, without giving her another chance to argue, he pushed into her.

Rika’s entire body jerked, her mouth open in a silent cry as his cock stretched her tight walls. The desk behind her rattled violently, chalk dust raining from the board as he filled her inch by inch.

"Too much?" he asked, though his hips didn’t stop pushing forward.

Her nails clawed at his back, her legs wrapping around his waist in desperation. "No... don’t stop... please, don’t stop."

That was all he needed. Renji slammed into her, the sound of their bodies colliding mixing with her moans. Her breasts bounced free of her bra as his thrusts grew brutal, her back arching against the chalkboard.

"Renji! Oh god....Renji!"

"Louder," he growled, one hand gripping her ass as he fucked her harder. "Let the whole damn school know you’re mine."

Her pride shattered completely. She screamed his name, her voice echoing down the empty halls. Her pussy clenched desperately around his cock, wet and messy, each thrust driving her closer to madness.

Her glasses slipped down her nose, fogging with heat, but she didn’t care. Her perfect, professional image was gone. She was just a woman—his woman—falling apart in his arms.

"Cum for me, sensei," he ordered, his hand reaching between them to rub her swollen clit. "Show me how bad you wanted this."

Her scream was raw when it hit. Her pussy convulsed around his cock, her legs locking tight as waves of pleasure crashed through her. Tears pricked her eyes, her body trembling as she came harder than she ever had in her life.

But Renji wasn’t done.

He lifted her effortlessly, slamming her down onto the desk. Papers scattered to the floor, pens rolling away as he pinned her there, pounding into her from above.

Rika’s hands scrambled for something to hold onto, finally clutching at the edge of the desk as her breasts bounced wildly with every thrust.

"You feel too good to stop," Renji groaned, his pace merciless. "I’m not pulling out."

Her eyes shot wide, but instead of protesting, her body betrayed her, her pussy clenched tighter, milking him. "Yes! Fill me, Renji! Please—fill me!"

That was all it took. With a deep, guttural groan, he slammed into her one last time and spilled himself inside her, his hot cum flooding her womb.

Rika’s body convulsed again, her second orgasm ripping through her as she felt him paint her insides. Her thighs quivered, her voice breaking into moans that would haunt her pride forever.

When it was over, Renji collapsed against her, their sweat-slicked bodies pressed together. She panted heavily, dazed, her hand weakly clutching his shirt.

Her classroom, her sanctuary of control, now smelled of sex. Her panties were still on the floor, her bra crooked, her hair wild.

And when Renji finally pulled back to look at her, his smirk returned. "Lesson over, sensei. You belong to me now."

Rika closed her eyes, shame and ecstasy mingling in her heart. She wanted to deny it, but her trembling body, dripping with his cum, told the truth.

She was his. Completely.
