CHAPTER 45: CHAPTER 45: MY AFTER-SPORT ACTIVITY

It was another day In school, The whistle cut through the morning air, sharp and commanding. Students groaned as they stretched, some fumbling through half-hearted warmups, others yawning like they hadn’t slept.

Mayumi barked instructions, her tone firm, but inside she was barely holding it together.

Her body still throbbed faintly from the night before. The phantom ache between her thighs wouldn’t let her forget, no matter how much she tried. She shifted on her feet, her shorts riding up slightly as a bead of sweat trickled down her back.

"Arms higher! Stretch properly or drop and give me twenty!" she snapped, trying to channel her usual iron authority.

But her voice cracked at the end.

She hoped no one noticed.

Unfortunately, someone did.

Renji.

He stood at the back of the formation, stretching leisurely, his shirt clinging to his toned chest, eyes gleaming with amusement. He didn’t even try to hide the way he was watching her.

Mayumi’s pulse quickened. She forced herself to look away, but it was already too late. Just meeting his gaze for a split second had made her body betray her again. Her thighs pressed together instinctively, the whistle trembling between her lips.

She turned sharply and barked, "Jog laps! Move it!"

The students groaned but obeyed, taking off around the field.

She needed space. Distance. If she could just keep moving, keep teaching, maybe she could forget how badly she wanted him to pin her down again.

But as the students jogged, Renji broke from the group and jogged toward her.

Mayumi’s breath hitched.

He slowed to a casual stop in front of her, smirk playing on his lips.

"Morning, coach," he said smoothly, sweat glistening on his skin under the sun. "You look... distracted."

Her throat tightened. "Get back in line, Sakamoto."

But her voice lacked the usual sharp edge.

He leaned in slightly, lowering his tone so no one else could hear. "What’s wrong? Didn’t sleep well last night?"

Her face burned. She tried to glare, but the heat in his eyes made her stomach twist.

"Don’t," she whispered, her voice trembling. "Not here."

Renji’s grin widened. He leaned even closer, his breath brushing her ear.

"Then tell me, Coach Mayumi... how many times did you cum last night?"

Her whole body stiffened. Her knees almost buckled.

She snapped the whistle sharply just to drown out the sound of her own pulse, yelling, "Two more laps! Faster!"

Renji chuckled, stepping back casually, as though nothing had happened. He turned and jogged off to rejoin the others, leaving Mayumi trembling in his wake.

She wanted to scream. She wanted to throw the whistle down and walk away. She wanted to demand why he was doing this to her, why she couldn’t stop thinking about him.

But worse... she wanted him again.

The shame cut deeper than ever.

Later that afternoon, Rika sat stiffly at her desk, her glasses fogged slightly as she tried to focus on lesson plans. She hadn’t gotten much rest either. Her body was sore in the most intimate ways, and every time she shifted in her chair, her cheeks flushed hot with the memory of Renji’s hands gripping her hips.

Reina wasn’t faring any better. She sat at her desk in the nurse’s office, staring blankly at paperwork. Her panties were damp again, even though she swore she wouldn’t let herself think about last night.

The system’s voice whispered faintly in Renji’s mind as he leaned back in his chair, watching both women from across the room.

[Lust Sync Active: Rika +65%, Reina +68%]

Renji smirked.

The final whistle of PE echoed across the emptying field. Students dragged themselves off toward the locker rooms, chatting and laughing, leaving only Mayumi behind to gather the scattered cones.

She bent down to pick one up, her ponytail swaying, sweat glistening on her arms. She looked every bit the tough coach, but her chest was heaving too fast, her jaw tight.

Because she knew he was still here.

Renji lingered near the bleachers, deliberately slow in tying his shoelaces, waiting until the others were gone.

Mayumi straightened, holding the cones tight against her chest, trying to steady her breath. She should tell him to leave. She should walk away. She should...

"Coach."

The word froze her in place. His voice carried that casual confidence that had been eating her alive since last night.

She turned slowly, and there he was....shirt clinging to his chest, sweat making his hair fall slightly into his eyes. His smile wasn’t mocking this time. It was softer. Deadly.

"Why do you keep looking at me like that?" she blurted out before she could stop herself.

Renji tilted his head, pretending not to understand. "Like what?"

"Like... like you own me." Her voice cracked. She hated how weak it sounded, how desperate.

He walked toward her, unhurried, eyes locked on hers. "Maybe because I do."

The cones tumbled from her arms and clattered onto the grass.

Her pulse hammered. She took a step back, but her body betrayed her, trembling with need instead of resistance.

"Don’t," she whispered. "The students—"

"They’re gone." His voice was calm, certain. He closed the distance, his hand brushing her cheek. "It’s just you and me now, Coach."

Her breath hitched. She should push him away. Instead, she leaned into his touch.

"I hate you," she murmured, but her body melted against him.

"No," he whispered back, his lips ghosting over hers. "You want me."

Then his mouth claimed hers, hot and forceful, and all her walls shattered.

Mayumi whimpered into the kiss, fists clenching in his shirt as he pushed her back against the bleachers. Her legs spread instinctively when his thigh pressed between them, the friction making her moan.

"Renji... we can’t..."

"Say that again while your pussy’s soaking through your shorts," he growled against her neck, biting just hard enough to make her gasp.

Her knees buckled. She clung to him, trembling, her breath ragged.

"I... I can’t stop," she admitted in a broken whisper.

His hand slid under her shirt, finding the swell of her breast, kneading it through her sports bra. She arched against him, biting her lip to stifle the cry that rose up.

"Good," he murmured. "Don’t stop. Don’t fight me. Just give in."

And she did. Her hips rolled against his thigh, shameless, her breath coming faster and faster as heat coiled low in her belly.

Renji smirked, whispering in her ear, "Last night wasn’t enough, was it? You want me again."

Her eyes squeezed shut. "Yes..."

"Say it louder."

"Yes! I want you!" she gasped, her voice breaking.

The system pulsed in Renji’s mind.

[Emotional Sync: Mayumi +45%]

[Lust Sync: Mayumi +71%]

Her nails dug into his shoulders as if she could hold onto something solid while her world spun out of control. She hated herself for craving this, but her body didn’t care. Her body had already chosen him.

The gym was silent except for the faint buzz of the ceiling lights. Renji’s breath came out in warm bursts, mingling with Mayumi’s ragged gasps as she leaned against the wall, sweat dripping down her temple. Her toned body, hardened by years of physical discipline, now trembled for reasons that had nothing to do with exercise.

"Mayumi-sensei..." Renji’s voice was low, almost teasing, as his hand brushed over the firm curve of her ass. "You’ve been holding back for way too long."

Her lips parted, but no words came out. The tough, commanding PE teacher, the woman who could shout down an entire class with a single look, was now pinned by a boy’s gaze, one that cut deeper than any whistle or lecture she’d ever given.

"You don’t know what you’re asking for," she whispered, her voice thick with tension.

Renji smirked. "I know exactly what I want."

He closed the space between them and kissed her. It wasn’t soft. It wasn’t gentle. It was hungry, fierce, and demanding....years of pent-up frustration colliding in one brutal clash of lips and tongues. Mayumi let out a muffled moan against his mouth, her nails digging into his back through his shirt.

Her body betrayed her. The same muscles that obeyed discipline, the same endurance that carried her through marathons, now quivered under the weight of raw desire.

"Renji..." she panted when their lips broke apart. "This is... this is wrong..."

"Wrong?" Renji’s hand slid beneath her gym shirt, his palm pressing against the firm plane of her abs. "No. What’s wrong is how long you’ve denied yourself this." His thumb brushed against the band of her sports bra. "What’s wrong is how much you’ve been pretending you don’t need it."

Her eyes fluttered shut, a shiver running through her spine as he tugged the bra upward, exposing the swell of her breasts.

"God damn..." Renji muttered, staring at the sight of her firm, perfectly shaped tits. "I knew you’d be built like this. Strong... but soft where it counts."

Mayumi’s cheeks burned crimson, her lips trembling as his mouth closed around her nipple. The wet heat of his tongue sent jolts racing through her body, her knees almost giving out.

"Ah—!" She gasped, clutching his shoulders for balance.

Renji suckled hard, then bit lightly before licking the sting away, his hand kneading the other breast. Her moans echoed in the empty gym, bouncing off the walls like a forbidden anthem.

"Say it," Renji growled against her skin. "Say you want this."

Her pride fought. Her discipline fought. But her body was already undone, trembling, soaking, betraying her with every shuddering breath.

"I... I want it," she admitted, her voice breaking.

Renji pulled back, a victorious grin spreading across his lips. "That’s more like it."

He dropped to his knees before her, fingers hooking into the waistband of her shorts. Mayumi’s breath caught as he tugged them down, along with her panties, revealing her bare pussy glistening with need.

"Fuck... you’re already dripping," Renji chuckled. "So much for discipline, huh?"

Mayumi bit her lip hard, trying to stifle a moan as his warm breath brushed her folds. But when his tongue darted out, slow and deliberate, her composure shattered.

"Renji—ahhh! Oh god—!"

Her hand flew to his head, gripping his hair as his tongue traced every contour, lapping up her wetness with merciless precision. His lips sealed around her clit, sucking hard, and Mayumi nearly screamed, her voice echoing through the gym like a desperate cry.

Years of restraint, of suppressing need, of pretending her husband’s betrayal didn’t scar her—gone in seconds as Renji devoured her like a starving beast.

Her thighs trembled violently. "I....I’m gonna ahhh!"
