Chapter 4: The Dance of Clasped Ecstasy

The 3.5mm thickness posed little difficulty. Luo Qiaorou planned to expand her cervical os to 4.5mm during this session before switching to a cervical balloon catheter for prolonged dilation.

The vibrator she intended to place in her uterus measured 2.8cm at its widest. Not that this naughty girl was being greedy—the smallest fully encapsulated, waterproof latex vibrator available happened to be this size. Complete waterproofing was non-negotiable for intrauterine use.

Manufacturers wouldn’t design vibrators specifically for uterine insertion. If they knew about girls’ plans to stuff their products into wombs, they’d likely dissuade them. After exhaustive searching, 2.8cm was the smallest she could find. The ¥300+ price tag wasn’t burdensome given her income anyway.

Given these constraints, the steel dilator’s 13mm maximum clearly wouldn’t suffice. It merely marked the starting point of her dilation plan. The real core of her strategy lay in the disposable cervical balloon catheter for sustained expansion.

This dilation device comprised a catheter, dual balloons (intrauterine and vaginal), a Y-connector, and inflation ports. As the names implied, one balloon would occupy her uterus while the other remained vaginal.

Injecting water through the Y-connector would inflate both balloons. Their proximity would create continuous compressive expansion within the delicate cervical canal, stimulating local prostaglandin synthesis to promote cervical ripening.

Unlike rigid dilators, water-filled balloons offered elastic, gentler expansion with less pain. However, inserting the soft catheter required preliminary dilation—hence the steel dilator’s role. Typically used for labor induction in pregnant women, this medical device couldn’t be directly applied to Luo Qiaorou’s immature, hypersensitive but non-gravid uterus.

Switching to the 4mm dilator brought noticeably stronger distension, though still tolerable. Her petite uterus seemed to climax again during insertion. After maintaining dilation for twenty minutes amidst lingering pleasure—waiting for the fullness to subside—she upgraded to 4.5mm.

“Mmmph~” The quiet girl couldn’t suppress a cute moan.

This time the distension intensified. As the steel rod slowly pressed into her tender cervix, her climaxing uterus quivered at the forced intrusion. Pleasure surged through her lower body—her eyes glazed with arousal, delicate toes curling, arched feet forming elegant curves.

Her sensitive core being directly targeted by this gradual expansion left the girl’s cheeks flushed crimson.

Though Luo Qiaorou adored this sensation, she knew cervical dilation shouldn’t progress too rapidly. Most case studies involved adult pregnant women tolerating 6-7mm dilators. For her immature uterus, 4.5mm seemed sufficient.

There was no rush anyway. The cervical balloon could handle gradual daily expansion—an experience she’d actually enjoy.

【4】Thirty minutes after fully inserting the 5mm dilator, the aching fullness finally began fading.

Removing the rod triggered another wave of melting pleasure. Her narrow cervical canal had adapted to this size, though requiring extra minutes. Worryingly, her long-dilated passage felt somewhat numb—a vagina shouldn’t stay gaping like this.

Picking up the sterilized balloon catheter, Luo Qiaorou noted its softness compared to steel dilators. Guiding it deep into her cervix required tools. She chose atraumatic oval forceps—their flattened, oval-tipped jaws gentler than standard cervical clamps.

Clamping the catheter with the forceps, she guided it into her abused cervical os. Though the orifice had closed somewhat post-dilation, accommodating the 3mm catheter posed no issue. Unlike the dilator’s intense fullness, this soft intrusion brought only a tickling foreign sensation—safe enough to enjoy.

Carefully advancing the catheter until the vaginal balloon nestled against her external os, she stopped.

With each balloon’s maximum capacity being 80ml, the novice drew full syringes—she’d stop if uncomfortable, ensuring no overinflation.

The Y-catheter split into two inflation ports: one for the intrauterine balloon, one vaginal.

Inserting the syringe into the uterine balloon’s port, Luo Qiaorou felt strangely aroused watching the screen display the catheter deep inside her.

The scene resembled manga villains injecting aphrodisiacs or semen directly into heroines’ uteruses via tubes. Initially resisting, the restrained heroines would helplessly watch their sacred wombs being filled—indignant at first, but soon overwhelmed by uterine euphoria.

If they were pumping in actual aphrodisiacs… well, that would make the consequences even better—or worse.

Luo Qiaorou absolutely adored this kind of scenario…

She slowly pressed the syringe plunger, feeling her uterine cavity gradually expand. Unlike rigid dilators, a gentle yet intensely satisfying pleasure slowly infused her womb through the catheter. The ballet-dancing girl, momentarily intoxicated by this uterine fullness, forgot to monitor the syringe’s gradations until realizing she’d already pushed the plunger all the way down.

“Oh dear… I really…” The careless Miss Luo intended to withdraw some fluid from the balloon, but paused before acting.

Her cheeks flushed crimson.

This 80ml sensation… Her greedy little womb felt reluctant to part with it.

“80ml… let’s keep it at 80ml. It doesn’t hurt anyway – feels rather nice actually.” Luo Qiaorou decisively embraced her mistake.

Unnoticed by her, the vaginal balloon was being partially drawn into the cervical canal due to the expanding intrauterine balloon. While a fully inflated uterine balloon caused minimal discomfort, combined vaginal inflation would be different.

Oblivious, Luo Qiaorou drew another 80ml of saline and connected it to the vaginal balloon’s filling valve. She barely depressed the plunger before intense distension made her stop.

She checked the scale

“Impossible! Only 20ml gives this sensation?” Puzzlement crossed her features until she noticed the vaginal balloon’s malposition on the screen – nearly entering the cervical os. After adjusting the catheter outward, the vaginal inflation eased though uterine pressure intensified.

But her rapacious little womb relished this compression, so Luo Qiaorou saw no need to reduce the uterine balloon’s volume.

“80ml for the uterus, at least 40ml for the vagina. Yes, that’s reasonable.”

Though claiming 40ml, she injected an extra 30ml to reach 50ml before withdrawing the syringe. Addicted to this expansion euphoria, she knew the soft balloon posed minimal risk despite the temporary dilation effort – effort she might secretly crave.

The screen revealed her petite cervical os completely obscured by the swollen balloon, visually demonstrating what 50ml truly meant.

“It expands this much? Then that 80ml inside must be…” Excitement colored her thoughts.

Unlike dilators losing effect after 20 minutes, these catheter balloons could provide gentle, sustained dilation for up to 24 hours with proper sterilization.

This meant continuous cervical dilation could be maintained through daily replacements.

Of course, strict antiseptic protocols were essential.

Luo Qiaorou opened sterile cotton packets – medical-grade cellulose that effectively segregated uterine and vaginal microbiomes.

Remaining spread open by the speculum, she used sponge forceps to pack her vaginal fornix completely with sterile cotton, avoiding contact with sensitive walls. The screen showed her deepest recess transformed into pillowy whiteness, only the plastic catheter protruding.

Only after completion did she release the speculum’s screw, removing this “villain” that had kept her spread open for nearly two hours.

Her elastic vagina gradually closed, leaving just the catheter peeking through rosy folds.

The protruding catheter held undeniable eroticism – neither the wire of a corded vibrator nor the antenna of a wireless one, but a direct conduit…

A conduit reaching deep into feminine depths…

Penetrating to the uterine interior.

Luo Qiaorou took commemorative photos with her phone.

First dilation procedure: complete success.

9 PM already. Rising from her spread-legged position maintained for hours left her thighs slightly sore, though trivial for a ballerina of her caliber.

She crossed and rubbed her legs, savoring the deep, sweet fullness in her womb – a more profound expansion than ever before, granting lingering afterglow reminiscent of climax.

The absence of vibrations did spark some regret.

There’s really nothing to regret, because Luo Qiaorou quickly found a vibrator of suitable size from the girl’s toy box and fed it to her insatiable pussy. The sterile cotton only filled the bottom of the vagina, leaving enough space to insert the vibrator, though not as deep as before.

Turning on the remote control and setting it to low vibration mode, the familiar comforting vibrations filled her pussy. Due to the catheter’s presence, the faint vibrations even reached her uterus, creating a ticklish sensation that made Luo Qiaorou play with the plastic catheter protruding from her labia, seeking the pleasure of deeper uterine stimulation.

“So comfy…” Only after inserting the vibrator did Luo Qiaorou feel settled. Seven years of daily masturbation had irreversibly altered her habits as a girl – she’d feel restless and anxious without toys filling her pussy.

Perhaps soon, she’d feel uncomfortable without toys in her uterus too. Though as a second-year junior high school girl, she couldn’t imagine what it would be like when becoming a mother someday.

For now, she just wanted to stuff the vibrator into her uterus.

At 9 PM, returning to “normal” required feeding both her pussy and stomach. But the thought of choosing clothes for food delivery made her settle for a simple salad. Compared to her lower lips, Luo Qiaorou treated her upper lips carelessly.

After eating came cleaning the scattered tools needing disinfection and sealed storage. The uterine balloon required daily replacement, meaning she had to reopen her body every day – proper storage was crucial.

The deep catheter and fully stuffed pussy meant every movement while cleaning tugged at her depths. Squatting, bending, standing – each motion subtly pulled at her most intimate organs. Unlike ordinary vibrations, this deep tugging offered interactive pleasure that made the girl want more exploration.

When finished, Luo Qiaorou felt reluctant to stop.

Squinting slightly, savoring the brewing pleasure, she stood on tiptoe in ballet’s fifth position, executing a perfect pirouette. The raised leg position felt oddly satisfying.

Blushing faintly, she danced following the pleasure – from room to corridor to spacious living room, the empty apartment her stage. Small jumps, backward kicks, unconventional yet graceful movements.

Her dancing radiated such elegant purity that even naked, it manifested pure human beauty – making any lustful thought feel like sacrilege against art.

Who could guess this elfin dancer was willingly undergoing continuous uterine expansion?

Luo Qiaorou loved ballet – or rather, performing ballet with cute toys inside her. Beneath elegant performances, tight leotards concealed a body addicted to lewd pleasures.

None knew the secrets hidden in her slender waist and flat abdomen – only she felt her immature yet wanton uterus constantly brewing pleasure. This perverse ecstasy brought both physical excitement and spiritual addiction.

Sweet addiction eroded her uterus, then her young body. The virgin womb opened prematurely just for pleasure – Luo Qiaorou knew her body was completely poisoned beyond return.

Which only excited her more.

In the empty apartment, her face betrayed her state through blissful expressions, while mysterious warmth accumulated deep inside, finally erupting in her delicate uterus.

This was Luo Qiaorou’s first uterine orgasm.

Tears welled from the sudden pleasure, yet her body maintained extreme elegance through morbid restraint. Unlike ordinary girls who collapse or tense up, she preserved her posture so perfectly that none could detect her climax.

Massive pleasure surged from her abdomen, yet her pathological restraint trapped it completely within her petite frame, as if preserving it forever.

Extending her right foot parallel to the floor, left foot pointed back, legs dramatically crossed clamping the catheter, hands poised like holding a skirt, she knelt gracefully in full extension.

The ballet girl offered a breathtaking curtain call on her empty stage, her climaxing body bowing to an unseen audience.
