Yuu Hoshimiya looked up, refusing to miss a second of this magnificent sight.
The breathtaking beauty of Shizuka's naked form instantly filled his vision.
In the massive wooden bath, her dignified composure had vanished.
In its place was the panicked, blushing vulnerability of a young girl in the throes of her first love.
Yuu felt a long-absent surge of thrill and raw excitement.
After all, he was currently in the home of the Osaka Police Superintendent.
And the Superintendent's wife was waiting for him in the bath.
Yuu, prepared for the occasion, wrapped a towel loosely around his waist.
He stepped up the wooden stairs and waded into the steaming water.
Shizuka huddled in the furthest corner of the tub, clutching a small towel to her chest.
She kept her eyes cast down toward the swirling mist on the water's surface, her face a deep, burning crimson.
Yuu moved toward her with a knowing smirk and sat directly beside her.
Their thighs pressed together beneath the water, the contact sending a jolt through Shizuka.
She didn't know what was happening to her; faced with Yuu's calculated pressure, she found herself unable to say no.
She hadn't dared to refuse him in the car, or at the crowded stadium.
Even just now, outside the bathroom door, she had remained silent and compliant.
Humans are creatures of habit; once she had retreated at the start, she found it impossible to be firm.
Especially when facing a man like Yuu, who knew exactly how to take an inch and turn it into a mile.
Furthermore, she had seen his staggering display of power in the dojo earlier.
Deep down, she felt that even if she refused, it would be a futile effort against his god-like strength.
With that excuse firmly planted in her mind, her internal tension eased slightly.
"Yuu... can I just... can I just scrub your back?" she whispered.
In Japan, there was an old custom of scrubbing the backs of honored guests.
Politely, it was called a custom; bluntly, it was historically an excuse for subordinates to offer their wives or daughters to their superiors.
Much like the kimono itself, which was originally designed for the convenience of spontaneous reproduction.
Most of Japanese culture was imported—historically from the Great Central Empire to the west, and more recently from the United States.
Many things changed flavor over the centuries.
The most classic example, aside from common idioms, was the globally known "seiza" or formal kneeling.
This habit resulted in generations of bow-legged citizens who suffered from leg numbness within minutes.
It happened because when the Japanese copied the posture from the mainland, they only saw the surface.
They didn't realize that beneath those wide robes, the mainlanders were actually sitting on tiny stools.
Shizuka was the same; she clung to her excuses, believing that once she finished scrubbing his back, she could leave safely.
Whether she was truly that naive or simply deceiving herself was anyone's guess.
Yuu ignored her question and spoke directly: "Madam, I can't reach my own back. I'll have to trouble you."
He turned his body, presenting his broad, muscular back to her.
Shizuka's face turned even redder, but as she looked around, she realized she hadn't brought any scrubbing tools.
It was impossible for her to climb out now to get a washcloth; Yuu's burning gaze felt as if it would melt her on the spot.
Looking at Yuu's back, Shizuka swallowed hard.
After a moment of hesitation, she let go of the towel covering her breasts.
She gripped the fabric with both hands and draped it gently over Yuu's shoulders.
She began to rub his skin, her heart hammering so hard she feared he might hear it.
Sensing the towel on his skin, Yuu raised an eyebrow.
At this distance, he could indeed hear the frantic racing of her pulse.
Once he felt his back had been sufficiently "cleaned," Yuu suddenly spun around to face her.
Shizuka gasped, her pupils contracting as she instinctively curled her shoulders inward to hide herself.
"Yuu! What are you doing?!" she cried out.
Yuu let his eyes wander shamelessly over her mature, lush body.
"Madam, back in the dojo, I didn't want you to strain yourself pulling those bamboo shards out of the floor."
"So I used my full strength to shake them loose. Now my arms are completely numb and weak."
"I'm afraid I'll have to trouble you with my chest as well!"
Shizuka knew perfectly well it was a lie—if his arms were weak, how had he carried her in here?
But looking into Yuu's dark, steady eyes, she couldn't find the strength to argue.
She hesitated, her eyes flickering toward the water before looking up again.
Eventually, she lifted her arms and began to scrub his chest with the towel.
The scene was incredibly bizarre and sexually charged.
Yuu watched her and let out a laugh, causing the blush on Shizuka's face to deepen further.
The great Matriarch of the Hattori family, inside her own husband's residence, was following his every command.
She was scrubbing him like a common servant.
The sensation was one of pure psychological and sensory satisfaction for Yuu.
The feeling of absolute conquest and achievement was something any man would find addictive.
Once she had finished a rough scrub of his chest, Shizuka spoke hurriedly: "I'm done, Yuu. I'm leaving now."
She started to rise, intending to head for the exit of the tub.
But after only two steps, she felt a hot, heavy hand clamp onto her abdomen.
With a sharp pull, her body fell backward, crashing into a solid, warm chest.
Yuu wrapped his arms around her and whispered, "That's not true. I didn't see you scrub yourself at all."
"Tsk, tsk. How can you be so unhygienic? I'll have to help you instead!"
He took the towel and pressed it against her back, causing Shizuka to shudder violently.
"Yuu... you said your arms were weak and you couldn't lift them!"
Yuu chuckled, "I lied. I can't believe you actually fell for it. You're adorably stupid, Madam!"
"You...!"
Shizuka was incensed; she began to struggle, splashing water everywhere.
But she couldn't break free from Yuu's iron grip. Instead, her soft back pressed even tighter against his chest.
On the highway leading toward Kazuha's home, Kazuha was dozing in the backseat.
In the driver's seat, Heizo Hattori was blissfully unaware that a "green hat" was being placed on his head.
He continued to chat with Ginshiro Toyama about police business.
"I can't believe the two of us couldn't take him even while working together," Heizo remarked.
"That kid's body is beyond human. I don't think he was even using his full strength..."
Ginshiro sighed but soon shifted the topic to a cold case.
"Heizo, do you remember the case in Osaka thirteen years ago?"
"You mean the unidentified charred body found in the drainage canal?"
Ginshiro pulled a plastic bag containing a small fragment from his pocket. "We found this scorched piece on that body."
"Hmph. We were talking about tossing that into the sea. Finding the rest is just a pipe dream," Heizo said, opening his left eye briefly before narrowing it again.
"Maybe not anymore. We found another charred body in the eastern canal with a matching fragment."
"The lab confirmed they were manufactured at the same time."
"It seems our theory from thirteen years ago was correct. The 'treasure' is still out there, waiting in silence."
Heizo opened his eye again, a sharp glint flashing. "That is a treasure the whole world would kill for!"
At the exact moment Heizo uttered the word "treasure," Yuu's hands were gripping a pair of his own treasures.
The two white towels slowly drifted to the bottom of the tub.
The more Shizuka struggled, the more useless it became; eventually, she was forced to sit directly on Yuu's lap.
Under the manipulation of his large hands, her body turned to jelly, and she finally gave up.
"Yuu, please... don't do this... don't..." Her eyes were filled with tears, looking as if she were about to break down.
Yuu whispered into her ear, "How could I not? This is a fair exchange. You helped me, now I help you."
"Besides, your body is so intoxicating, Madam. I simply can't help myself!"
Yuu's index finger traced a line along Shizuka's shoulder, leaving a trail of goosebumps in its wake. Her heart fluttered wildly.
At his words, the tears she had been holding back finally overflowed. The great Matriarch was weeping.
"Yuu... you're a bully!"
Seeing her cry, Yuu turned her body around to face him. He cupped her face in his hands and used his thumbs to wipe away the tears.
With a gentle smile, Yuu leaned in close, his hot breath hitting her skin as he spoke tenderly: "Don't cry. It breaks my heart."
With his mix of aggression and sudden tenderness, even a mature woman like Shizuka was powerless to resist.
Her tears stopped.
Then she saw Yuu's face close in, and her lips were captured in a forceful, deep kiss.
In the tub, Yuu held her head as he tasted her mouth thoroughly.
Beneath the water, Shizuka's hands opened and closed, fluttering in indecision before finally reaching out to clutch Yuu's waist.
Feeling her touch, Yuu felt a surge of triumph. He moved his hands down, taking her small hands and guiding them to a specific location.
After a long moment, Yuu released her lips. Shizuka was panting, her face flushed and her eyes hazy with desire.
Yuu kept his arms wrapped around her waist.
"Madam, I truly just wanted to soak with you and help you wash up. I have no other intentions."
"Mmm..." Shizuka didn't believe a word of it.
Yuu lifted her up, forcing her to stand upright in the water.
She stood before him like a fresh lotus rising from the pool.
Being out of the water felt like losing a layer of protection; Shizuka looked panicked, her legs trembling as she gripped the wooden edge of the tub for support.
Yuu's hand moved to the spot where he had left the maple leaf mark in the car. He stroked the vibrant red skin.
"Madam, I didn't realize you'd kept the gift I gave you!"
"What gift? I... I just haven't looked at it!" Her denial was laughably weak.
Yuu chuckled and used his thumb to rub the mark with force.
"That gift is a bit outdated anyway. Let me give you a new one!"
"A new gift?"
"A magical thing that will help you get 'thoroughly clean' inside and out!"
Shizuka was confused, having no idea what a "cleansing stick" was, but she soon realized the true meaning of his words.
Yuu smiled and used his hand to spread her trembling, jade-like legs. He gripped his massive "cleansing stick" and brought it into contact with her wet, slippery slit.
Shizuka let out a cry of shame and irritation; the moment the tip touched her, a flood of juices erupted from her core, drenching his hand and his weapon.
She was stunned; she finally understood what the "cleansing stick" was.
Looking at her shocked face, Yuu laughed: "Are you satisfied with my equipment, Madam? I'm going to make you very clean now."
He rubbed the head of his cock against her clitoris in slow circles, making her body shudder and her hips twist frantically.
She couldn't stop herself from thrusting her snow-white mound upward, rotating her hips to meet his movements as more fluid poured from her.
Looking at the exaggerated size of the weapon, Shizuka was terrified, but a primal, long-suppressed desire flared up within her.
Since getting pregnant with Heiji, she had slept in a separate room from Heizo. She hadn't been intimate with a man in nearly twenty years.
She had almost forgotten what her husband's equipment even looked like.
But one thing was certain: it didn't look like this.
It probably wasn't even half the size...
Shizuka's expression shifted from shock to bashful submission. She closed her eyes and let Yuu handle her.
Yuu wrapped her arms around his neck and supported her waist. He guided his eager weapon to the entrance of her tunnel and pushed inside.
Years of repressed hunger were ignited in a single instant. Her mature, seductive body adapted to the intrusion with staggering speed.
After a brief flash of stretching pain, Shizuka accepted him completely.
The feeling of being filled, the slickness, the tight fit, the warmth...
Yuu marveled at how perfectly a "ripe" wife suited him. It was as if she had been born to be his sexual partner; they were perfectly matched from the very first time.
Shizuka's experience was even more intense.
As the "cleansing stick" drove deep into her body, it felt as though a tsunami were crashing through her. She almost lost her last bit of dignity and begged him to keep going.
She gritted her teeth and pressed her forehead against his chest, her excitement reaching a peak before he even started moving.
Being taken while standing was a first for her, and the stimulation was overwhelming.
Shizuka hadn't expected him to be so forceful.
Her body was split open by the massive weapon as it drove all the way to her hilt in one stroke.
In that instant, pleasure exploded like a volcano in every nerve, every muscle, and every pore. Every fiber of her being screamed with joy.
Her tight tunnel was breached by his power, and she felt as if her entire body were being stretched to its absolute limit by the intense bliss.
His weapon wasn't just thick and long; it possessed a special magic.
The head of his cock was burning hot, sending endless waves of pleasure through her.
The heat inside her made her body shake violently, and a massive amount of fluid gushed from her, running down her legs and into the bath.
Yuu felt his weapon being squeezed and pulsed by her internal walls.
The sweetness of her response was so intense she felt as if she would stop breathing. She hugged Yuu tighter in her daze.
Overwhelmed by the pleasure, Shizuka lost her self-control and proactively sought his mouth with hers.
She even pushed her tongue out to entwine with his, dancing in a clumsy, eager rhythm.
Yuu held her slick waist and pulled her flush against him.
He leaned down to lick her vibrant red lips before sucking on them greedily.
At the same time, his hips began to thrust with powerful, rhythmic motions, driving his cock deep into her over and over.
The beautiful wife's body rose and fell with the impact of his thrusts.
"Madam, is this more exciting than doing it in bed?"
"Mmm... I don't know... don't ask that... ah...!"
Shizuka's brow was furrowed, her moans growing louder and more soulful with every strike.
Yuu's hand slid up her perfect curves, gripping her soft, high-peaked breasts with a mix of gentleness and power.
Shizuka felt a surge of heat in her chest. "Oh...!" she cried out sweetly, closing her eyes.
She gave herself over to the pleasure of Yuu kneading and flicking her nipples.
His hands worked her breasts relentlessly; her skin was incredibly soft yet possessed a firm elasticity.
He never grew tired of playing with them, especially the sensitive buds at the tips. The friction from his palms alone made him feel fantastic.
A warm current of affection rolled through his heart. He tightened his grip on her and thrust even harder.
Every time he lunged, his cock drove through her small of her back to strike her cervix directly.
The steam on their skin mixed with their sweat, coating their naked bodies in a slick sheen. Shizuka's pale skin was flushed pink, providing a constant visual stimulus for Yuu.
The intensity of his strikes increased, and within ten minutes, she was drenched in sweat.
"Madam, are your legs tired?" Yuu asked caringly, slowing his pace.
"Mmm... my feet are numb..." she whispered. The small show of consideration left her feeling a strange sweetness in her heart.
Yuu pushed her back against the wooden edge of the tub. Her eyes went wide, unsure of what he was doing.
"This way you won't get tired, Madam..."
Yuu smiled. "Wrap your arms around my neck. Don't worry..."
Shizuka did as she was told. Yuu pressed his body against hers, then slid his hands under her butt and lifted her up.
Her feet left the floor entirely. To maintain her balance, she naturally hooked her legs around his waist.
The "cleansing stick" began its work again.
With her back against the tub wall and her arms around his neck, her rounded buttocks bore the brunt of his fierce impacts.
"Ah... mmm... oh... Yuu... mmm..." she gasped.
"Does it feel good, Madam?" Yuu asked.
"Mmm..." came a high-pitched nasal response.
Under the relentless assault of his thrusting, she felt as though she were about to reach the summit at any moment.
Shizuka's face was bright red, and her jade-like body was vibrating with tremors.
She gripped the edge of the wooden tub so hard her knuckles turned white.
She bit her lip to keep from screaming, but her breathing was becoming increasingly heavy and ragged.
Just as she was about to lose her voice to a scream of ecstasy, her son's voice rang out from outside the door.
Heiji Hattori had been lying in bed looking at his phone, but he couldn't settle down.
He had only heard Ran return to the guest rooms earlier.
This meant Yuu Hoshimiya hadn't come back yet.
And when he passed his mother's room, it was dark and empty.
This late at night... were the two of them together?
With his father out of the house, the feeling was not good at all!
It wasn't that he didn't trust his mother; it was that he knew all too well how much women were attracted to Yuu.
His heart filled with doubt, Heiji turned around and headed for the large bathhouse near the courtyard.
He soon reached the door. The interior was lit with a bright, orange-yellow glow, but the courtyard itself was empty.
Inside the bathhouse, the steam was thick, and the sound of splashing water was constant.
"Who's in there? Is it Teacher Hoshimiya or Mom?"
Shizuka's pupils contracted to pinpricks. The blood drained from her face, and the scream in her throat was swallowed back into her gut.
She was paralyzed with terror, having no idea what to do.
"Is anyone there? If not, I'm coming in!"
Hearing this, Shizuka managed to force words out.
"Mmm... Heiji... it's me. I thought you were using the shower in the front wing? Why are you here?"
She didn't even notice that her voice was broken by sharp gasps for air.
Outside, Heiji laughed and rubbed his head. "I was looking for Teacher Hoshimiya. I had some questions about the case today!"
Shizuka's panic intensified. She spoke hurriedly.
"Oh! Mr. Hoshimiya? He... he finished his bath and left already. He should be in his room!"
"But I just came from the guest rooms. He wasn't there!"
Shizuka looked back at the man behind her, then regained a shred of composure and spoke again.
"Oh! Silly me! He mentioned he was hungry after his bath. I told him there was some cake in the dining room fridge. He must be in the kitchen eating!"
Outside, Heiji smiled. "Alright then! Enjoy your bath, Mom. I'll go find him!"
Heiji turned to head toward the dining room, but his face turned incredibly dark.
The sound of splashing water at the start!
The long silence before she answered!
The heavy gasping in her voice!
He wasn't a child. He knew exactly what those signs meant.
Heiji was in a foul mood. He decided to check the dining room first; if Yuu wasn't there, he was heading straight for the dojo.
There was a real katana hanging on the wall there.
But before he reached the dining room, he spotted a familiar figure in the courtyard.
It was Yuu Hoshimiya, wearing a yukata!
He was standing beneath a lush maple tree, talking on his phone. The voice was unmistakably his.
Heiji froze. To get from the bathhouse to the courtyard, one had to use the hallway.
If Yuu was here, then Mom really was alone in the bath.
"Good grief," Heiji muttered. "Mom, if you're alone, why make all those noises? It's totally misleading!"
Then again, he thought, she and Dad have slept apart for so long. It's natural for her to have needs!
Heiji breathed a sigh of relief. He didn't want to disturb Yuu's call, so he headed back to his own room.
Back in the bathhouse, shortly after Heiji left, the water in the wooden tub erupted into activity once more. The seductive body shifted through countless positions until the sound of sobbing, ecstatic cries filled the room!
This was, of course, the work of the magic barrier.
A low-level barrier blocks sound and sight; a high-level one creates a false environment and misleads cognition.
Just like a perfect crime, rather than hiding the tryst, Yuu simply created an "impossible phenomenon" that Heiji couldn't solve.
After this, even if Heiji noticed something suspicious later, he would likely find his own logical reasons to dismiss it.
Yuu moved rhythmically beneath the water. Shizuka thrust her pale, rounded buttocks upward, meeting every impact with everything she had. Both were lost in bliss.
The rhythmic splashing of water filled the room once more, like a tide that refused to recede.
