Chronolust Temptation [18+] High S*xual Content
Ch.5 Gym Day with S*xy Mother

The sun filtered through the kitchen window, casting a warm glow over the breakfast table where Hayao, Mai, and Yumi sat. The aroma of miso soup mingled with the scent of grilled mackerel, a traditional Japanese spread laid out before them: steaming rice, pickled radish, and a small bowl of tamagoyaki. It was a typical Saturday morning, but Hayao’s mind was far from routine.

He poked at his fish, gathering courage. “Mom,” he said, voice steady but heart racing, “I’ve been thinking. I want to start going to the gym with you. To get in shape before university.”

Mai, mid-sip of her green tea, raised an eyebrow, her dyed blonde hair catching the light. A playful smile spread across her face. 

“Oh, really? That’s great, Hayao!” She leaned over and gave his shoulder a light slap, her touch lingering just long enough to send a shiver down his spine. “Trying to look good for all the girls at university, huh?”

Yumi, lounging across the table with her long black hair spilling over her shoulders, snorted into her tea. Her voluptuous figure, softer than her mother’s but no less striking, shifted as she leaned forward. 

“Yeah, Hayao, got your eye on someone already? Trying to impress the ladies?”

Hayao’s cheeks flushed, but he forced a laugh. “N-no, it’s not like that. I just want to be healthy.” 

Inside, his thoughts churned. If only you knew, Yumi. It’s not the girls at university I’m thinking about. His gaze flicked to Mai, who was now spooning miso soup, her lips glistening as she blew on the steaming broth.

Mai chuckled, her dark eyes sparkling with mischief. “Sure, sure. Well, I’m happy to take you with me. How about this afternoon? I was planning to go anyway.”

“That sounds perfect,” Hayao said, relief washing over him. The thought of being alone with his mother, watching her move, sweat, and flex, made his pulse quicken.

Yumi shook her head, her full lips curling into a smirk. “Wish I could join, but I’ve got a ton of assignments to finish for uni. You two have fun doing gym stuff or whatever.” Her tone was teasing, but her eyes lingered on Hayao a moment too long, a flicker of something unreadable in them.

After breakfast, Hayao helped clear the table, his hands brushing against Mai’s as they stacked dishes. Each touch was electric, fueling his anticipation. He retreated to his room to change, pulling on a simple t-shirt and shorts, but his mind was already at the gym, imagining Mai in her workout gear.

***

The local gym was a modern facility, its glass walls reflecting the afternoon sun. The air inside was cool, scented with a faint mix of disinfectant and sweat. Treadmills hummed softly, and the clank of weights punctuated the quiet, a hallmark of Japanese gym etiquette where noise was kept to a minimum.

Mai emerged from the locker room, and Hayao’s breath caught. Her tight black leggings hugged her curvy hips and toned thighs, while a bright pink sports bra accentuated her large breasts, fuller since giving birth to him and Yumi. Her dyed blonde hair was tied into a high ponytail, swaying as she walked toward him with a confident stride.

“Ready?” she asked, her smile warm but unaware of the storm she was stirring in her son.

“Yeah,” Hayao replied, swallowing hard, his eyes struggling to stay on her face.

They started with the treadmills. Mai hopped onto one, her fingers deftly setting the speed. “Let’s warm up first,” she said. “Just walk for five minutes to get your heart rate up.”

Hayao took the machine next to hers, mimicking her settings. As they walked, he stole glances at her. Her strides were smooth, her body moving with an effortless grace. A light sheen of sweat formed on her neck, trickling down to her cleavage, and Hayao felt a familiar heat pooling in his groin. Focus, you idiot, he chided himself, but it was futile.

After the warm-up, Mai cranked up the speed to a jog. Hayao followed, his legs protesting, but his eyes locked on her. Her breasts bounced with each step, the sports bra doing little to hide their motion. Her leggings stretched taut over her ass, the fabric outlining every curve. Hayao’s mouth went dry, his sadistic side whispering dark fantasies—pinning her down, hearing her gasp, controlling her every move.

“Keep up, Hayao!” Mai called, her voice light, snapping him back to reality.

They slowed to a walk, and Mai led him to the weight machines. “Let’s try the leg press,” she said, adjusting the weight stack. “It’s great for your quads and glutes.”

She sat on the machine, her legs spread slightly as she placed her feet on the platform. With a smooth push, she extended her legs, her thighs flexing, her glutes tightening. Hayao watched, mesmerized, imagining those legs wrapped around him, her body yielding under his touch.

“Your turn,” Mai said, hopping off.

Hayao took her place, the seat still warm from her body. He struggled with the weight, his form shaky. Mai stepped closer, her hands brushing his thighs as she adjusted his feet. “Push through your heels,” she instructed, her voice soft but firm.

The touch sent a jolt through him, his cock twitching in his shorts. He completed the set, his face flushed from more than just exertion.

They moved through other machines—chest press, lat pulldown, shoulder press—Mai demonstrating each with precision. Hayao’s eyes traced her every move: the ripple of her back muscles, the swell of her breasts as she pressed the weights, the sweat beading on her skin. Each correction she made—her hands on his arms, his shoulders, his hips—pushed him closer to the edge.

Between sets, they talked. Mai asked about his university plans, her tone motherly but her body anything but. Hayao answered mechanically, his mind elsewhere. What would it be like to use the stopwatch? To freeze her mid-motion, her body mine to explore? The thought was intoxicating, but the gym’s public setting held him back.

After the machines, Mai suggested free weights. She picked up dumbbells and showed him bicep curls, her arms flexing with each lift. “Keep your elbows close,” she said, standing behind him to guide his form.

Her body pressed against his back, her breath hot on his neck. Hayao’s hands trembled, the dumbbells nearly slipping. Her perfume, floral and musky with sweat, filled his senses. He wanted to turn, to grab her, to claim her right there.

They finished with core exercises on the mats. Mai did crunches, her abs contracting, her breasts rising with each lift. Hayao lay beside her, his own crunches half-hearted, his eyes glued to her. When she bent over to stretch, her ass presented to him, he nearly groaned aloud.

As they wrapped up, Mai wiped her face with a towel, catching Hayao’s stare. “What?” she laughed. “Got something on my face?”

“No,” he stammered. “Just… impressed by your strength.”

“Thanks, honey,” she said, oblivious to his hunger. “It takes dedication.”

Mai suggested they use one of the gym’s private saunas, a rarity in Japan, to relax their muscles. The small, wooden room was stifling, the heat wrapping around them like a blanket. They sat side by side, towels draped over their bodies, sweat dripping freely.

Mai leaned back, eyes closed, her towel slipping to reveal more of her cleavage. “This feels so good,” she murmured, her voice low and sultry.

Hayao nodded, his gaze fixed on the curve of her breasts, the way they glistened with sweat. His cock strained against his towel, and he shifted to hide it. The stopwatch, tucked in his gym bag, called to him. One click, and she’s mine. Frozen, helpless, perfect.

“So, Hayao,” Mai said, opening her eyes, “excited for university? It’s a big step.”

“Yeah,” he said, voice tight. “But I’m nervous. New environment and all.”

“You’ll do fine,” she assured, squeezing his arm. Her touch was fire, her fingers lingering. “You’re smart, capable. And now, you’re going to get buff.”

Hayao forced a smile, his mind screaming. Sex would make for a great workout, too. A part of him reveled in the thought, but guilt gnawed at him too.

The sauna’s heat enveloped Hayao and Mai, a cocoon of steam and cedar that intensified the fire raging within him. Mai’s words lingered in the air, her hand still warm on his arm from moments ago: “You’ll do fine,” she had said, her fingers trailing fire across his skin. “You’re smart, capable. And now, you’re getting buff.” Her touch, innocent yet electrifying, had pushed him to the edge.

Hayao’s heart thundered as he sat beside her, their towels barely concealing their sweat-slicked bodies. The sauna was small, its wooden benches low, the air thick with humidity. A bucket of water sat in the corner, its ladle dripping softly, the hiss of steam punctuating the silence. Mai leaned back, eyes closed, her face serene, unaware of the storm brewing in her son’s mind. Her towel had slipped, revealing the deep curve of her cleavage, her large breasts straining against the fabric. A bead of sweat traced a slow path down her neck, disappearing into the valley between them.

Under his towel, the stopwatch pressed against his thigh, its cold metal a stark contrast to the heat surrounding him. It was a relic of the goddess Benzaiten, imbued with the power to freeze time during sexual acts. His fingers twitched, itching to grasp it. The temptation was unbearable, his sadistic desires clawing at his restraint. He glanced at Mai again, her lips parted slightly, her chest rising and falling with each breath. She was perfect, and she was his.

His hand moved, almost of its own accord, closing around the stopwatch. He hesitated, a flicker of guilt piercing his lust. She was his mother, the woman who had raised him, loved him unconditionally. But that thought only fueled his desire, the taboo nature of it intoxicating. With a deep breath, he clicked the button.

Time stopped. The steam froze in midair, the dripping water halted, and the world was silenced. Mai sat motionless, a statue of beauty, her expression unchanged. Hayao’s breath hitched, his cock already hardening at the sight of her vulnerability. He stood, his towel falling away, exposing his arousal. He didn’t care. No one could see, no one could judge. This moment was his alone.

He approached her slowly, savoring the anticipation. Her skin glistened, every curve accentuated by the dim light filtering through the sauna’s small window. The young boy reached out, his fingers brushing her shoulder. Her skin was warm, soft, slick with sweat. He trailed his hand down his mother’s arm, feeling the subtle strength beneath, then up to her neck, where her pulse would have been if time still flowed. He leaned in, inhaling her scent—floral perfume mixed with the musky tang of sweat. It was intoxicating.

His hands moved to her towel, trembling with excitement. With a gentle tug, he loosened it, letting it fall to her waist. Her breasts were revealed, full and heavy, their size amplified by years of motherhood. Hayao’s mouth went dry, his eyes drinking in every detail: the smooth, creamy skin, the dark areolas, the nipples already hardening in the warm air. They were magnificent, a forbidden treasure he had dreamed of for months.

He cupped one breast, its weight filling his hand. It was firm yet yielding, the flesh molding to his touch. He squeezed gently, watching as it spilled between his fingers. His thumb brushed her nipple, circling it, feeling it stiffen further. A low groan escaped him, his cock throbbing with need. He took the nipple between his fingers, pinching lightly, imagining her gasp, her moan. But she remained still, a perfect canvas for his desires.

Lowering his head, he took her nipple into his mouth, sucking greedily. The taste of her skin, salty and sweet, drove him wild. His tongue swirled around the bud, flicking it, teasing it. He buried his face in her breast, nuzzling the soft flesh, losing himself in its warmth. He moved to the other breast, giving it the same attention, his hands kneading both, unable to get enough. In his mind, Mai was writhing, her hands in his hair, begging for more. The fantasy fueled his actions, his sadistic side reveling in her helplessness.

His hands roamed lower, caressing her toned stomach, the curve of her hips. He slipped a hand between her thighs, parting them slightly. The heat there was intense, her folds slick with sweat—or perhaps arousal, he dared to hope. He traced her slit with a finger, feeling her softness, her warmth. She was tight, inviting, and he couldn’t resist. He pushed a finger inside her, slowly, savoring the sensation. She enveloped him, her walls gripping his finger. He added another, stretching her, his thumb finding her clit and rubbing in slow circles.

Hayao’s breath came in ragged gasps, his cock aching for release. He withdrew his fingers, bringing them to his mouth, tasting her essence. It was exquisite, a mix of salt and sweetness that made him crave more. Kneeling before her, he spread her thighs wider, exposing her fully. He leaned in, his tongue darting out to taste her. He licked her slowly, exploring every fold, every crevice. Her clit swelled under his attention, and he sucked on it, imagining her cries of pleasure. In his fantasy, she was screaming his name, her body trembling with ecstasy.

But in reality, she was silent, still. It didn’t matter. This was for him, a stolen moment of absolute control. He feasted on her, his hands gripping her hips, his tongue relentless. The forbidden nature of it—his mother, his goddess—pushed him to the edge. He wanted to take her fully, to bury himself inside her, but he held back. There would be other times, other opportunities. For now, this was enough.

After what felt like an eternity, he pulled away, his lips glistening with her taste. He rearranged her towel, covering her modesty, ensuring everything looked as it had before. He returned to his seat, wrapping his towel around his waist, his cock still hard but his mind sated—for now. He picked up the stopwatch, its weight a reminder of his power. With a final glance at Mai’s frozen form, he clicked the button.

Time resumed. The steam billowed, the water dripped, the heat returned. Mai stirred, blinking, her expression confused. A deep blush spread across her cheeks, her hand fanning her face. “Wow,” she murmured, her voice husky, “this sauna is hotter than I remember. I think I need to get out.”

Hayao nodded, his voice tight. “Yeah, me too.” He struggled to keep his composure, his body still buzzing with arousal.

They gathered their things and left the sauna, the cool air of the locker room a shock to their heated skin. Mai glanced at him, her blush lingering, but she said nothing. They parted to shower separately, and Hayao let the cold water cascade over him, trying to quell the fire within. But it was no use. His mind replayed every moment: her breasts in his hands, her taste on his tongue, her body his to command. His cock hardened again, and he stroked himself under the spray, coming quickly with a muffled groan.

In the lobby, Mai waited, her hair damp, her street clothes clinging to her still-warm body. She smiled, oblivious to his transgression. “That was intense,” she said, laughing softly. “We should do this again.”

“Definitely,” Hayao replied, his smile masking the hunger in his eyes.

The walk home was quiet, the evening air cool against their skin. Mai chatted about dinner plans, but Hayao was distracted, his thoughts consumed by her. Every step she took, every sway of her hips, reminded him of what he had done, what he wanted to do again. He stole glances at her, her blonde hair catching the streetlights, her curvy figure outlined by her tight jeans. She was his obsession, his forbidden fruit.

At home, Yumi was buried in her books, her long black hair spilling over her shoulders. She looked up as they entered, her voluptuous figure soft and inviting compared to Mai’s toned physique. “Back already?” she asked, her eyes lingering on Hayao. “How was the gym?”

“Great,” Mai said, heading to the kitchen. “Hayao kept up like a champ.”

Yumi smirked, her gaze flicking over Hayao’s arms. “Looking good, bro. The gym’s doing wonders.” Her tone was teasing, but there was a heat in her eyes that made Hayao pause. Did she sense something? Or was it her own secret desire, the attraction she hid so well?

He brushed it off, his focus on Mai. “I’m gonna shower again,” he lied, needing an excuse to escape. In his room, he closed the door, leaning against it, his heart racing. The stopwatch sat on his desk, its presence a constant temptation. He picked it up, tracing its surface, imagining the next time he would use it. Perhaps when Yumi was at university, leaving him and Mai alone. The thought sent a thrill through him.

Dinner was a blur. They ate grilled fish, rice, and miso soup, the conversation light but charged with undercurrents. Mai’s hand brushed his as she passed the rice, her touch electric. Yumi’s eyes darted between them. 

“You’re quiet, Hayao,” Mai noted, her voice soft. “Everything okay?”

“Just tired,” he said, avoiding her gaze. But when she smiled, saying, “You look more like your father every day,” his breath caught. The mention of Daigo, her late husband, stirred something in him—jealousy, desire, possession.

After dinner, he helped with the dishes, standing close to Mai at the sink. Their arms brushed, her perfume filling his senses. She hummed a tune, unaware of the storm she was stirring. When she reached up to tuck a strand of hair behind her ear, her shirt lifted, revealing a sliver of her toned stomach. Hayao’s cock twitched, his mind flashing to the sauna.

In his room, he lay on his bed, staring at the ceiling. His room was sparse, a samurai poster on the wall, a family photo on his nightstand. He picked up the photo, studying Mai’s smile, so like the one she wore today. His feelings for her had grown over the years, from innocent admiration to this dark, consuming lust. The stopwatch had unlocked his desires, giving him power he never dreamed of.

He undressed, lying naked under the sheets, his hand finding his cock. He stroked himself slowly, picturing Mai’s frozen form, her breasts, her wetness. In his fantasy, she was awake, eager, her body yielding to his every touch. “Hayao,” she whispered in his mind, “fuck me.” The thought pushed him over the edge, his release spilling over his hand with a groan.

As he cleaned himself, he heard Mai’s voice calling goodnight. He responded, his voice steady despite the turmoil within. He knew he was crossing lines, violating taboos, but he couldn’t stop. The stopwatch was his key, and Mai was his prize.

He checked Yumi’s schedule, noting her upcoming presentation. Next week, she’d be out late, leaving him and Mai alone. He smiled, a cruel edge to it. He would plan, wait, and strike. The goddess Benzaiten had given him this power, and he would use it to claim what he wanted.

Sleep came, filled with dreams of Mai’s body, her moans, her surrender. Hayao was lost in his desires, and there was no turning back.
