Chapter 1 — Miwa's First Experience

"Don't worry. I won't push you too hard..." Daniel Naigai whispered softly into her ear, gently pulling Grace Miwa into his embrace.

Though her body remained stiff with tension and fear, Grace Miwa silently nodded, her face lowered in quiet submission.

(Now that I've come this far, there's no turning back...) She told herself as she yielded her trembling body to the moment.

Daniel Naigai swung the door wide open and lightly pushed against her lower back, urging her forward.

She had married her childhood sweetheart two years ago. At just twenty-four, Grace Miwa was still a young housewife.

She wasn't unattractive by any means, but she wasn't the type to draw passionate attention from men. Her naturally introverted nature often left others with a vague, unremarkable impression.

Recently, however, Grace Miwa had begun to sense a hidden masochistic side buried deep within herself.

(I want to be utterly ruined... Just once, I want to reveal my true self completely...)

This vague, unsettling thought had slowly begun to take root in her heart.

On weekends, her husband would routinely demand sex, but due to his inexperience, his foreplay was brief and mechanical—entirely self-centered.

Grace Miwa rarely reached climax. Her growing dissatisfaction with these encounters may have been fueling her twisted desires.

One afternoon, Grace Miwa turned on the family computer for the first time—bought originally for her husband's work. She typed in the web address of a BDSM site she'd seen advertised in a women's magazine.

(To feel excitement like this just by looking...?)

Nearly every photo on the page depicted women treated like toys.

Women deprived of freedom. One woman had a strap-on inserted behind her; another bore red welts across her buttocks from a whip.

Yet all of them seemed to wear expressions of bliss.

The hazy image in Grace Miwa's mind grew sharper, clearer—she was beginning to understand what she truly desired.

(It's the same... I'm just like these women...)

She became engrossed in the stories and confessions posted online.

She found herself helplessly aroused by scenes of women being tormented in fiction.

She reread her favorite passages over and over.

Unconsciously, her fingers began to stroke the lower part of her abdomen. She was shocked by how wet she had become.

This became her daily ritual.

After a month, she began participating in the BDSM site's online chat rooms, even exchanging emails with dominant men.

It surprised her how boldly she could behave online—so unlike her timid self in real life. For the first time, Grace Miwa felt like she had found where she belonged.

After several exchanges, she agreed to meet a man named Daniel Naigai—just once, she told herself.

This was an audacious act for someone as fearful as Grace Miwa, the result of long, agonizing deliberation.

(What if there are marks on my body...? What if he starts stalking me...? What if my husband find out...?)

These thoughts swirled in her head, making her tremble right up until the moment she arrived at the meeting place.

Yet she believed that by being honest with her own desires, she might finally transform the quiet, shadowed version of herself.

The daily emails from Daniel Naigai overflowed with gentleness—polite, dignified in tone.

(This man... he'll be okay.)

And so, Grace Miwa made her decision.

On the drive to the hotel, Daniel Naigai made jokes that made her laugh often. Her anxiety gradually began to fade.

(He's just as I imagined—such a wonderful man...)

Grace Miwa thought this as she gazed at Daniel Naigai's profile while he drove.

"From now on, this is BDSM. Listen carefully to what I say."

Daniel Naigai whispered as he locked the door behind them.

"Yes..."

She answered, but fear still gripped her.

She had never entered a hotel with a man she just met. Not knowing what Daniel Naigai would do to her only deepened her unease.

The room was filled with strange BDSM equipment neatly arranged.

(I'll be tied to that St. Andrew's cross, my body touched... forced to spread my legs on that padded bench and expose everything...)

Her daily fantasies were becoming real. Grace Miwa felt a sharp, electric thrill cutting through her persistent anxiety.

"Stand in front of me and slowly undress."

Daniel Naigai said, lighting a cigarette.

"Umm... can I take a shower first?"

"No. You can't."

Grace Miwa hesitated but began removing her clothes as instructed.

She carefully folded her blouse and slowly slid down her skirt. She rolled down her stockings and placed them in the nearby laundry basket.

Daniel Naigai sat calmly on the bed, silently watching her every move.

Not touching her, not speaking—just watching her undress—was deeply humiliating and painful.

"Is that enough...?"

Grace Miwa stood in front of Daniel Naigai, hands clasped in front of her.

"Take everything off. You still have your bra and panties on."

"Yes...? You want me to take them off now?"

"Yes. Don't make me repeat myself."

Hesitantly, Grace Miwa reached for the clasp of her bra. She slipped her arms free, instinctively covering her nipples with one hand.

(Do I really have to undress myself completely...?)

She glanced at Daniel Naigai, hoping for some reassurance, but he remained expressionless, saying nothing.

Slowly, Grace Miwa removed her last piece of clothing. She covered her groin with both hands, her entire body flushed red, head bowed before Daniel Naigai.

"I'm undressed."

"Move your hands. Raise them above your head."

"A-ah, yes..."

This was a lewd, depraved situation she had never experienced with her husband.

Naked before a man, while Daniel Naigai hadn't even removed his shirt.

Her breasts, nipples, the dark patch of pubic hair between her legs—everything was exposed.

Daniel Naigai merely observed her, amused, not even attempting to touch her. He rested his chin on one hand, leaning forward slightly, studying her body for a long moment.

"Are you embarrassed?"

"Yes. So embarrassed..."

"Your chest is rather underdeveloped, isn't it?"

"Yes..."

"Still, I like your delicate figure. Your skin is soft, too."

Grace Miwa's mind went numb from the intense humiliation.

She stood completely naked while Daniel Naigai remained fully clothed, showing no sign of arousal, calmly evaluating her body piece by piece.

It felt as if she were being auctioned off. The hierarchical power dynamic of BDSM cut deep into her bones.

(Why... why am I feeling this... getting aroused just from being watched...?)

Grace Miwa was already wet. She could feel her lower body pulsing with heat. She felt like she might go mad from shame.

A faint, strange pleasure wrapped around her body, sweet and sorrowful at once.

"Turn around."

Grace Miwa, hands still raised, turned her back to Daniel Naigai.

"Small buttocks. Heh... quite cute, actually. Now, spread your legs."

Grace Miwa hesitated.

"No... please..."

She shook her head slightly, her voice hoarse.

She knew she was wet—she didn't want him to see her already-drenched sex.

"Don't talk back. Now, spread them wide."

Harsh words poured out. A light slap landed on her buttock.

"Ugh..."

Daniel Naigai slid his foot between hers, forcing her legs apart.

"No... I don't want to."

Her balance broke, her legs spreading to shoulder width—then a slick trickle of arousal slid down the inside of her thigh.

"Please... don't look."

"Hahaha. What an incompetent woman. I haven't even done anything yet..."

"I'm so embarrassed..."

"Stay still. Don't move."

Grace Miwa raised her hands back to her head, twisting her body in helpless humiliation.

Her ears and neck turned bright red as she kept shaking her head from side to side.

"Wider....Wider."

Grace Miwa obeyed, spreading her legs and exposing her married woman's sex.

"Good. Now place both hands on your knees and push your hips back."

"A-ah... yes..."

Grace Miwa's sex was exposed. Her slender labia were already parted.

Between the slightly opened petals, a glistening drop of arousal clung, ready to fall.

Her anus, too, was boldly displayed before Daniel Naigai, the tiny bud twitching and contracting with each of her involuntary shudders.

She had exposed what should only be seen by her husband to a man she had just met.

The thought of how vulgar she must look in Daniel Naigai's eyes made her mind spin with shame.

"Oh, it's flowing again. Why are you so vulgar?"

"I-I'm sorry..."

The pooled arousal dripped down, leaving a glistening trail on her thigh.

"Good posture, Grace Miwa. I'd love to show this to your husband."

"A-ah. Please... don't mention my husband..."

Daniel Naigai continued to humiliate her with words, watching her flounder with evident amusement.

"A woman who gets aroused just from being watched. You're already soaked like this..."

"Y-yes... I-I'm aroused."

"Heh heh. Honest... and quite cute. Now I'll test your tightness. Don't move."

Daniel Naigai raised his right middle finger. He brought the fingertip slowly toward the center of the woman before him.

Even at this point, Daniel Naigai had not touched any other part of Grace Miwa's body.

Now, he inserted just his fingertip precisely into her vagina.

"Ugh..."

Without warning, the sudden penetration made Grace Miwa's body lurch forward.

She squeezed her eyes shut, biting her lip, desperately trying to maintain her posture. Daniel Naigai's finger slid in effortlessly.

"You're very wet, Grace Miwa."

"Please... don't say it... don't say it..."

Daniel Naigai twisted his finger a few times, then curled it like a key and pressed firmly against the upper wall of her vaginal canal.

"A... ah..."

Grace Miwa's knees trembled, as if she might collapse at any moment.

Her desperate, shamed body was brought to the brink of collapse by just a single finger.

"I told you not to break your posture."

"A-ah... but, but..."

"Don't touch the floor with your hands. Use your legs."

Grace Miwa obeyed, bracing her legs, fighting the intense, piercing sensation running through her body.

But each time Daniel Naigai moved his finger slightly, an electric current shot up her spine and the strength drained from her lower body.

The pressure of her tightening vaginal walls suddenly intensified. Layer upon layer of mucous membrane clung tightly around his finger.

"N-no... I can't... I'm going to come like this..."

"Oh? Wait, you can't come yet. I'm worried about your future. But Grace Miwa... you might be quite the skilled lover."

Saying this, Daniel Naigai abruptly pulled his finger out from the clinging, quivering vaginal walls.

"You can't come yet. Don't think badly of me."

"A-ah..."

Grace Miwa's posture collapsed. She fell to her hands and one knee.

When she looked back at Daniel Naigai, her eyes held a complex mix—relief, lingering longing, accusation.

Naked Grace Miwa crouched on the floor on all fours. The only thing allowed on her body was a faded red dog collar.

A thin metal chain extended from the collar, held in Daniel Naigai's hand as he sat on the bed.

Daniel Naigai had prepared a thin whip, placed beside him. The collar and whip were complimentary props provided by the room.

"You're just like a bitch in heat, aren't you? Look at how wet you are? Vulgar, always waiting for a male—just like a bitch, right?"

Sitting on the bed, Daniel Naigai used his toes to gently sway Grace Miwa's breasts.

"I... I'm a vulgar bitch..."

Grace Miwa whispered, staring at the floor.

(I am a bitch... I can feel how wet I still am, just as Daniel Naigai said...)

Grace Miwa had never imagined she could be such a lewd woman. Yet she continued to grow wetter, arousal building without pause.

Each word from Daniel Naigai shook her soul. She felt herself being conquered, inch by inch.

"Then crawl around the bed like a bitch. Slowly. I said slowly."

"Yes."

Grace Miwa began circling the bed slowly, centered on Daniel Naigai. The chain on her collar jingled softly.

Daniel Naigai didn't even look at her, instead pulling out a BDSM magazine he'd been carrying under his arm and beginning to read.

With her sex and anus fully exposed, Grace Miwa continued crawling on the floor like an animal.

How many times had she circled the room? Occasionally, Daniel Naigai would suddenly tug the chain or lightly strike her buttocks with the whip.

Tears suddenly spilled from Grace Miwa's eyes. She sobbed as she crawled.

"Why? Why are you crying?"

Daniel Naigai lifted his face slightly from the magazine and looked down at her.

"A-ah... it's nothing..."

"Don't stop. Keep crawling."

Again, the whip cut through the air, a sharp sting piercing her buttocks.

Her tears wouldn't stop. It wasn't from sadness over her pitiful state—crawling on the floor, scorned as a bitch.

It was because each time she was whipped, she felt a thrilling arousal. That was what made her cry. Something she didn't want to admit.

She hated the sticky wetness on her thighs. The flowing arousal soaked deeper, spreading wider with every step on all fours.

In the eerie light of the BDSM room, the inner part of her thighs glistened.

Daniel Naigai watched from behind, a satisfied expression on his face.

"Why did you come here today? Didn't you come here to be abused? You wanted to do these shameful things, didn't you?"

"Yes... that's right."

Grace Miwa answered, sitting upright at Daniel Naigai's feet. It was her honest truth.

She had never felt such excitement, such dazed euphoria before.

"Then beg me. Ask me to abuse you more. Beg me to make you do even more shameful things."

"Yes..."

Grace Miwa sat upright and bowed her head to the floor.

"Please, Daniel... abuse me more. I want to do even more shameful things. Please..."

Something inside Grace Miwa felt lighter. An honest version of herself had emerged.

It felt strange how her trust in Daniel Naigai was growing.

"Let me reward you. Keep your legs spread like that."

Grace Miwa slowly parted her knees, which had been pressed tightly together. Beneath her thin pubic hair, the thick bud of her clit peeked slightly.

Daniel Naigai removed only his right sock and slid his foot between her knees.

Grace Miwa's body stiffened, and she instinctively tried to close her legs.

"P-please... at least use your hand..."

"Why? A woman like you is fine with a foot. Now, spread them. I'll be nice to you..."

"A-ah... that's too much..."

Reluctantly, Grace Miwa spread her legs and accepted Daniel Naigai's foot. Immediately, the top of his foot began moving back and forth along her slit.

"Uuuh... a-ah..."

Grace Miwa's body arched backward. Pleasure surged, soaking her sex instantly. But when Daniel Naigai tried to insert his big toe, Grace Miwa panicked and lifted her hips.

"Don't resist. Put your hands behind your back and use your hips to enjoy it."

Grace Miwa quietly lowered her hips and began moving her entire lower body against the top of his foot.

"Kuh... a-ah..."

"Good... that's it... keep going..."

Sweat trickled down Grace Miwa's lewd face.

(I'm feeling pleasure from his toes...)

An intense, nerve-tingling sensation surged up her spine. His big toe slid sticky into her entrance.

"Ugh..."

Her vaginal opening contracted, arousal spilling out.

"Seems you're enjoying it quite a bit. It suits you well, heh heh..."

Inside her sensitive mucosa, his thick big toe wriggled wildly.

"S-stop... a-ah..."

Her lips trembled, moans spilling out uncontrollably. Hands behind her back, Grace Miwa arched her back slightly, her sweat-soaked body trembling.

"Alright, I'll let you come. You'll come from a toe. That's what suits a woman like you."

"A-ah... more... more..."

Squelching, lewd sounds echoed. His foot moved faster, rubbing her clit.

"Ugh... I-I'm... I'm coming..."

Grace Miwa cried out in a vulgar voice, signaling her climax. Her throat twisted, sweat droplets fell. Her sex contracted, arousal gushing out like urine.

Grace Miwa arched her back and convulsed two or three times. Then she collapsed forward, her body falling onto Daniel Naigai's foot.

Grace Miwa's wrists were now bound behind her back. A black cloth covered her eyes.

She lay face down on the floor, knees and face touching the ground, legs spread, her buttocks raised high.

The same posture that exposed every part of her to Daniel Naigai.

"Now I'll give you what you've been longing for most."

Daniel Naigai said.

(Longing...?)

Grace Miwa didn't know what he meant. She heard a sound behind her, like a bottle being opened.

(Scary...)

Alone in the dark, Grace Miwa trembled with fear. Yet a faint anticipation kept her in the lewd posture.

What Daniel Naigai pulled from the bottle was lotion he'd bought at the front desk.

He scooped some of the slick liquid and smeared it over Grace Miwa's rear rosebud.

"Ugh..."

Grace Miwa instinctively lowered her hips to avoid his finger. A slap landed sharply on her buttock.

"Ugh..."

"I'll be nice to you—don't move!"

"But... it's dirty there..."

Grace Miwa pleaded desperately in a weeping voice.

"I'll put my finger into this dirty place now. Be grateful."

Daniel Naigai used both hands, rubbing in circles to gently spread each tightly clenched wrinkle.

"A-ah... no..."

Grace Miwa arched her back, pressing her face to the floor, writhing. She had never been touched there before.

Yet she knew such sex existed—and deep down, as Daniel Naigai said, she had desired it.

(My anus... is being touched... like a toy...)

Just thinking this sent a powerful wave of pleasure surging from the core of her body.

Her oval-shaped anus, slick with lotion, stretched left and right, up and down.

After persistent stimulation, the muscle gradually loosened—then suddenly, Grace Miwa let out a fart.

"Stupid..."

"A-ah... I'm sorry... really..."

"Why is everything about you so loose—here and there?"

"I'm so ashamed... a-ah... I want to die..."

Blushing all over, Grace Miwa shook her head and began sobbing.

Daniel Naigai's touch slowly changed—his fingers began to press shallowly, exposing mucosa with each movement.

"Have you ever put anything inside here?"

"N-no..."

"Really? Then this will be your first time losing your anal virginity."

Daniel Naigai smoothly inserted his index finger into her well-lubricated anus.

"A-ah... a-ah..."

Grace Miwa straightened her back, writhing. Her bound hands, fingers curled like keys, clawed at the air as if grasping for something.

Daniel Naigai pushed his finger deeper into the center of her beautiful heart-shaped buttocks.

"Ugh... it's dirty... don't put it in any further..."

Overwhelmed by this alien, unfamiliar pleasure, Grace Miwa shook her head wildly, lost and confused.

"How does it feel to have a finger in your ass? Must be intense, huh... heh heh..."

"U-ugh... don't move... please don't move..."

"The real massage starts now. How about this?"

Keeping his index finger inserted to the second knuckle, Daniel Naigai began rotating his wrist in small circles.

"A-ah... h-huh... ugh..."

It was a sensation of her anal muscles melting with heat. The thin wall of her rectum transmitted stimulation to her vaginal opening.

"Stop... stop... please... stop now..."

"As you feel like this... you're such a pervert..."

Pushing his index finger deeper, Daniel Naigai inserted his thumb into Grace Miwa's dripping vaginal entrance.

He pinched the thin membrane of her internal wall and rubbed his fingers together.

In that instant, a blissful moan escaped Grace Miwa's lips.

"I-I'm... I'm coming again..."

Grace Miwa's sweat-soaked naked body began trembling violently.

"If you want to come, say it. Say:'I'm Grace Miwa, a lewd bitch who feels pleasure through her ass hole.'"

"Uuuh... G-Grace Miwa is... a lewd bitch who feels through her ass hole..."

"Say it again."

"Grace Miwa is a lewd bitch who feels through her ass hole..."

"Heh heh... good, good. I'll let you come like this."

Daniel Naigai used his other hand to rub Grace Miwa's clit. It was hard, swollen to more than double its size.

"Kuh... h-uhh..."

Grace Miwa convulsed like an animal, climaxing in an instant as her vagina and anus contracted simultaneously.

She twisted, collapsing from her kneeling posture—but Daniel Naigai kept his fingers inside, and her muscles contracted violently again.

Sweat trickled down Grace Miwa's lewd face in streams.

Afterward, Daniel Naigai pulled his fingers from her clinging mucosa and wiped her lower body with a tissue.

Then he gently stroked Grace Miwa's hair, which still breathed with the warmth of afterglow.

Daniel Naigai pulled Grace Miwa into his arms and lifted her onto the bed. He kissed her mouth fiercely.

Bound at the wrists, Grace Miwa responded with a strong embrace, surrendering to his suddenly gentle, tender touch.

They never met again. Their email exchanges continue to this day.

To Grace Miwa, Daniel Naigai became a trusted confidant, a friend with whom she shares lighthearted banter in online chat rooms.

"As promised, we'll end it here. I can't explain it well, but that's what my BDSM is about," Daniel Naigai said the day they parted.

(Thank you, Daniel. I feel like I've learned so many things...)

As always in the afternoon, Grace Miwa was in her usual world of chatting. It was her favorite BDSM online chat room.

And as always, her fingers danced rhythmically across the keyboard.

"Hello? Who's there?"
