Chapter 1 The Making of Chocolate

Eiko fearfully watched the dark chocolate bubbling in the cauldron. As an untouched virgin, pouring this scorching, viscous substance into her body was proving difficult to accept.

Yet upon reflection, wasn’t this very reason why “Chocolate Confession” was hailed as the most irrefutable love confession?

Eiko had no confidence whether that person would accept her feelings. Though she considered herself adequately cute and believed ordinary boys wouldn’t reject her, that particular individual kept unsettling her heart.

Thus Eiko chose this solemn—perhaps even extreme—confession method.

“If I go this far, rejection should be impossible”—thus reasoned the maiden.

“Should be about time.”

Observing the thermometer on the cauldron reaching 52℃, Eiko switched to constant temperature mode. Testing with her fingertip found the warmth still bearable.

“Mm…” Eiko removed her skirt and panties. Even in her locked bedroom, imagining subsequent events made her cheeks flush crimson.

The bubbling chocolate filled the small room with sweetness. As cotton panties slid down, fresh floral fragrance emerged through the confectionery aroma. Both fragrances twined into a strangely pleasant mixture.

Inspecting her intimate area—white and tender like exquisite pudding—Eiko unconsciously stroked the soft mound. Peculiar pleasure surged through her body, making the delicate “pudding” glisten moistly.

Pink blossomed on her cheeks as fragrant air thickened.

Her pinky traced the tight seam, hooking a white string. Gentle tugs sent fabric friction vibrating through vaginal walls to her womb’s depths, inducing tremors in her abdomen.

“Aaah!”

“One never gets used to this…”

Gripping bedsheets with white silk-clad toes, the maiden cautiously extracted the foreign object deep within.

“Chocolate Confession” required extensive preparation. For days Eiko had been “marinating” vanilla-soaked white pantyhose inside herself using specialized tools with clip-tipped rods, painstakingly stuffing them into her uterus until filling her vaginal canal.

This nightly ritual involved extracting day-old pantyhose soaked internally and replacing them with fresh vanilla-infused ones.

A pure white string gradually emerged from taut pink folds. Vanilla-soaked lace unfurled like summer lilies blossoming as silk brushed tender flesh. Vaginal muscles alternately clenched instinctively yet reluctantly yielded to the withdrawing fabric.

“Mmmph…”

Her slender frame trembled during extraction. Though weak-kneed, Eiko carefully maneuvered to preserve her hymen.

However paradoxical it seemed after half-month of vaginal/uterine stuffing, Eiko remained technically virginal.

Preserving maidenhood symbolized devotion—proper conduct paradoxical to failure.

The fragile cherry required delicate handling. Daily pantyhose insertion through the hymen’s tiny aperture brought exhaustion and humiliation mitigated by soft silk material manageable through practiced technique—remarkable accomplishment for pure highschool maiden.

Not that such achievement fostered pride.

Extracted halfway, stretched pantyhose astonished Eiko. The expanded lace resembled magic trick material being dragged from her intimacy.

Though vanilla essence was colorless floral fragrance, pantyhose retained pristine whiteness.

Allowing Eiko to wear them to school next day.

Three pantyhose comprised her confession toolkit: one worn normally, one internally embedded, one vanilla-marinating at home.

Every day after returning home, Aiko would take off the pantyhose she wore on her legs and throw them into the rapid washing and drying machine. Then she would take off the pantyhose “worn” inside her body and replace them with a new pair soaked in vanilla essential oil for a day. By this time, the pantyhose in the washing machine would be almost clean and dry. She would retrieve them and soak them in essential oil to serve as the next day’s “embedded” pair.

After reinserting the pantyhose, Aiko could continue her daily routine—completing homework, eating, bathing, or sleeping—all while wearing the day-soaked pantyhose. Though initially uncomfortable, it gradually became pleasurable. She even felt emptiness when not wearing them.

Occasionally, when unnoticed, she would intentionally clench her legs to savor the unique thrill of her vagina and uterus being fully stuffed with white silk pantyhose.

The pantyhose that had been inside her body all day would be tossed into the rapid washer, not to be worn externally until the next day.

As for the pair that had filled her body overnight, it naturally wouldn’t be removed so quickly. They had to be “worn” all day, repeating the cycle each evening.

These were the rules of “Chocolate Confession”—though Aiko made minor adjustments. For example, she insisted on washing the pantyhose despite knowing her generation’s genetically optimized bodies produced no detectable odor, her personal fastidiousness demanded it.

The durability of the pantyhose and Aiko’s meticulous care allowed the three white silk pairs to fulfill their purpose. The one in her hand would be tomorrow’s lucky pair for the confession.

Aiko brought the damp pantyhose closer, inhaling the crisp vanilla scent. Her uterus, she mused, must be thoroughly permeated by it. The specially formulated oil didn’t just soak internally—it subtly altered her secretion system. Girls who underwent Chocolate Confession often gained lifelong, delicate body fragrances, a reward for their dedication.

Yet on days when she wore the pantyhose, whenever classmates asked about her pleasant aroma, Aiko would blush and deflect the topic.

The pantyhose remained soft, pristine, and undamaged. Pride swelled in her as she admired them; half a month of rotation hadn’t marred their perfection.

But she soon halted her fidgeting, perhaps reminded that half the garment still nested deep within her uterus.

Extracting the silk from her vagina was mild compared to withdrawing the uterine portion. The silken fabric sliding through her delicate cervix sent her petite womb quivering. Fortunately, after weeks of conditioning, her inner depths had softened like molten rice cake, easing the process.

The oil not only relaxed her uterus but also hypersensitized the小巧 flesh vessel, transforming it into an exquisitely responsive organ.

“Nngh~” Midway through pulling out the uterine pantyhose, Aiko’s legs snapped shut, her back arching taut as unique pleasure crested into climax.

Every extraction triggered an inevitable orgasm, one she’d grown accustomed to. Yet her endurance dwindled—today’s climax struck halfway, making the remaining extraction even harder.

But leaving the silk lodged inside would prevent chocolate infusion. Forcing herself past the post-orgasm sensitivity, Aiko resumed slowly withdrawing the snugly wrapped fabric.

Glossy fluids trailed the stocking’s exit, intensifying the vanilla fragrance.

By full removal, heightened arousal teetered at another peak, but lacking further stimulation, her body gradually settled.

Clutching the extracted pantyhose, Aiko—legs still clenched against lingering sensations—quietly deposited it into the washer.

Returned to her room, she positioned herself on a U-shaped stand, hips elevated above her waist. To prevent movement during chocolate infusion, she securely strapped her legs to the frame.

Fastened in place, her right hand reached a crucible of melted chocolate, while tools and materials lay within left-hand grasp.

First came bladder emptying—post-chocolate sealing would permit no urination. Aiko parted her pale folds, guiding a catheter into the tiny urethral opening.

Weeks prior, a permanent indwelling catheter with one-way valve had been implanted for the confession ritual, ensuring zero urine contact with her “food-grade” vaginal canal. Despite her bladder now suffused with vanilla essence from adjacent uterine saturation.

Carefully inserting the catheter past the valve, amber urine drained into a prepared bottle. After flow ceased, a medical syringe applied suction to confirm total evacuation before removal.

Now the main event: Aiko retrieved an electric dilation ribbon.

The ribbon—a stiff, braided tool specific to Chocolate Confession—came in vaginal or uterine variants. Hers was naturally the latter; after weeks of preparation, skipping this step would waste her efforts.

These styles symbolized differing commitments: vaginal for marriage intent, uterine for immediate childbearing readiness. Yet sincerity-wise, both represented peak devotion—reaching confession stage itself was the ultimate gesture.

Petite Aiko had chosen the uterine path, self-conscious about her narrow vaginal canal.

Though…

“It’s quite deep…”

Aiko held the electro-expansion ribbon against her lower abdomen, noticing it was just two or three centimeters away from her navel. The depth made the girl feel a bit fearful. However, thinking that the ribbon would align her uterus directly with her vagina through expansion, this position seemed about right.

After mentally preparing herself, the girl began inserting the ribbon into her body. The intertwined ribbon formed a rod-like shape no thicker than an ordinary pencil, easily passing through the hymenal opening.

Watching the ribbon gradually disappear into her pale, delicate slit, the sensation of a foreign object deepening inside made her cheeks flush, as if she were doing something naughty.

“Mmm!”

The ribbon’s tip pressing against her cervix sent a blush-inducing wave of pleasure. Aiko gently rubbed the small opening with the ribbon’s end, coaxing it to relax and open. Warmth spread inside her, as if the fading climax was about to return.

“Mmm~”

She pushed the ribbon into her softened cervix. Though the imagined climax didn’t arrive, her uterus trembled excitedly from the foreign object’s intrusion.

“You’re… such a lewd little thing,” the girl murmured, chastising her own uterus.

She continued pushing the exposed ribbon deeper. Her soft uterus was forced into a straight line with her vaginal canal by the rigid ribbon. Long-term exposure to special oils had made her connective tissues pliable and highly elastic, allowing her uterus to shift from its usual 90-degree angle to a straight alignment.

This was necessary to later remove the solidified chocolate. Though the tissues were flexible, ligaments still anchored the uterus firmly to prevent it from being dragged out entirely.

The repositioning didn’t cause discomfort, but created a peculiar sensation in her lower abdomen.

The rigid part of the ribbon was fully inserted past the hymen, leaving only its soft ends outside.

“Here we go,” she whispered, as if encouraging herself.

Aiko connected a dry battery’s terminals to the ribbon’s ends. A tingling numbness spread inside, accompanied by expanding pressure. The ribbon slowly widened a cavity in her uterus and vagina. Cool, sweet-tanged air rushed into her secret garden through the negative pressure, sending a chill through her core.

The electro-expansion ribbon’s middle section was woven with special fibers for rigidity, while the untreated ends merely conducted electricity. When connected to a standard 1.5-volt battery, the current activated the ribbon, causing its reinforced section to expand and create a cavity.

“Nngh… so full…”

Despite the swelling sensation, she persisted for thirty seconds until the ribbon reached standard dimensions. Through her slightly parted hymen, one could now see all the way to her fallopian tubes.

Aiko touched her soft lower abdomen, surprised to feel the ribbon’s hardness beneath her skin. Though the shopkeeper had called this a “small size,” it still felt overwhelmingly large inside her petite frame.

She pushed aside her doubts—the ribbon’s rigidity would last only five minutes before softening. She needed to pour the chocolate quickly.

Inserting a thin-necked funnel into her hymenal opening, she steadied it with one hand. The crucible’s thermometer showed 53°C, slightly hotter than intended. The warm metal felt almost scorching to her touch.

“It’s fine… this temperature is manageable,” she reassured herself, rubbing her fingers.

Tilting the crucible, she poured steaming chocolate through the funnel into her defenseless depths. Thick, sweet liquid cascaded inward with searing heat.

“Aahhh!!!”

The molten chocolate assaulted her uterine cavity, scalding tender flesh. Though not truly harmful, the sudden heat triggered convulsions in her lower abdomen. Her sensitive inner walls, unprepared for the assault, translated the temperature into overwhelming pleasure.

Thankfully, being tightly strapped to the frame prevented accidents. The contrast between her writhing abdomen and immobilized lower body created a perverse thrill.

“It’s… so hot inside… nngh~”

Despite her gasps, she kept pouring—the ribbon’s time limit demanded urgency.

After initial shock, the heat became tolerable. The warm chocolate filling her body even felt comforting.

As viscous liquid filled her uterus and vaginal canal, air was gradually displaced.

Aiko blushed at the sensation of being slowly filled to capacity—embarrassed, yet undeniably pleasured.

After the last drop of chocolate sauce dripped into the funnel, the small cavity was perfectly filled. The girl’s calculations were precise – when pulling out the funnel, the chocolate sauce exactly reached the level of her hymen.

Eko took out a small ball and inserted it into the tiny hole in her hymen. The thick chocolate sauce overflowed slightly from the edges as the foreign object entered, contrasting sharply with her pure white soft skin. The intracorporeal ball rapidly expanded, tightly sealing the vaginal entrance while leaving two gift ribbons extending outward. The pale slit tightened again into a tiny crevice, appearing undisturbed.

Only two pink gift ribbons protruded from the narrow crevice, accompanied by traces of sticky liquid that looked like evidence of sneaking sweets.

After wiping away the overflowing chocolate sauce with tissue, the dexterous girl tied the ribbons into an adorable bow, hinting at sweet contents within. Then she applied a heart-shaped waterproof sticker over her vulva, completely sealing both the sweet spot and the bow, finally exhaling in relief.

The final mission was now complete. All that remained was waiting for the chocolate to solidify inside, imprinting her shape, before presenting this embodiment of a girl’s strongest affection to her beloved.

Eko felt an internal relaxation as the ribbons’ rigidity timed out, transforming into ordinary soft fabric. However, her straightened uterus maintained its straight-aligned position with the vaginal canal due to flexible ligaments, preserving the completely accessible posture.

The thick chocolate sauce adhered more closely to her inner flesh walls.

Imagining how precisely the chocolate mold would reveal her internal contours – even clearly showing the fallopian tube openings – made the girl blush with embarrassment.

“Mmm… It feels so full inside… How comfortable.” Blushing, Eko caressed her lower abdomen. The burning sensation persisted internally, still maintaining its viscous state. Experiencing this wondrous feeling of being filled with sticky fluid, she inexplicably felt shy.

“Really, didn’t feel anything during preparation, why be embarrassed now?” After self-mockingly muttering, she put on cotton panties that outlined her cute slit, concealing the secret within.

“Should do homework first.” Despite being completely filled internally, the girl didn’t neglect her studies – an ability honed through half-month’s practice maintaining normalcy in this state.

The molten chocolate’s lingering warmth tinged her cheeks pink. This special chocolate had a higher solidification point around 45°C, maintaining firmness at body temperature. Her body warmth slowed the cooling process, allowing ample time for detailed anatomical imprinting.

Once solidified, extraction could only occur by pulling the ribbons – simultaneously surrendering virginity. Retrieving the chocolate after acceptance thus symbolized a ritualistic virginity offering.

Compared to stockings, the chocolate felt more viscous and penetrating due to cooking warmth. Writing homework, Eko endured each centimeter of her precious privates being violently filled with molten euphoria. The sweet liquid’s high-temperature invasion merged chocolate fragrance with her vanilla body scent, permeating rosy skin with lovesick sweetness.

Gradually, internal arousal intensified, becoming particularly noticeable when lying down. As chocolate began solidifying from viscous to rigid, Eko felt profoundly penetrated – unsurprising with her fully crammed uterus.

Her hands involuntarily caressed the sealed lower body, rubbing her clit through the heart sticker. Tightly pressed thighs rubbed together as she faintly twisted her hips, savoring the foreign sensation.

Beneath the covers, the girl quietly climaxed in midnight’s depth, the chocolate’s vanilla essence growing purer.

The sated girl gradually slept. In quiet breaths, solidifying chocolate permanently fixed her internal contours in climax’s shape.
