Chapter 1 - First Encounter at a Comic Convention

Archived Version

In the convention floor's roar, that figure in black stood out like a wound.

No taller than five feet, black rabbit-ear headpiece swaying gently with each step. The bunny-girl kigurumi was a full-body design, sheathing her from neck to toe — black stockings tracing every curve of her legs with precise indulgence, small heeled shoes making her already petite frame look impossibly compact. The most arresting detail was her chest: the suit was visibly strained there, full curves pushing against the fabric, at least a C-cup, trembling faintly as she moved. The crotch panel was especially taut, a deep crease pressed into the material, as though one more inch of tension would split it open.

Lin Yuan had been staring for the entire afternoon.

He knew his particular weakness — figures wrapped head-to-toe, fully concealed, yet betraying the body underneath with every contour. The total-coverage look. Like a gift waiting to be unwrapped. When he finally worked up the nerve to approach her, she only nodded quietly. The ventilation mesh at the mouthpiece of the headpiece gave nothing away. No sound of breath came through.

“How much?” Lin Yuan asked it plainly.

She raised a gloved hand and typed a number on her phone screen.

It was exactly one year's worth of his savings. He barely hesitated.

The hotel room glowed in soft, ambiguous amber.

When the bunny-girl kigurumi lay on top of him, Lin Yuan felt the weight — not heavy, but undeniably real. Black-stockinged thighs pressed across his abdomen, warmth seeping through the fabric. He reached out tentatively, palm flat against her back, trailing down the spine, finding the latex-wrapped curve of her ass. She didn't resist. She arched slightly, tilting her hips to let his hand slide easier into the cleft.

His breathing quickened.

He pushed his trousers down. His erect cock pressed against the inner thighs wrapped in black stocking. The texture was fine and smooth with just enough friction. He rocked his hips slowly, letting the head rub against the nylon surface. His other hand found the hidden side opening in her suit — discreet by design, just wide enough to admit his fingers. When his fingertips touched the softness of her breast, a low sound of satisfaction rose in his throat.

C-cup. Fuller than he'd imagined.

He pinched the nipple, rolling it gently. Her body shuddered — then her thighs clamped together, muscle tightening, squeezing his cock between them harder. She began moving her hips on her own, accelerating the friction of his head against the crease of her thigh.

Shhk — shhk — shhk…

The sound of nylon dragging against skin filled the quiet room with startling clarity.

Then Lin Yuan noticed something wrong.

She was breathing — he could see the mesh at the headpiece's vent shifting faintly. But there was no sound. No exhale, no gasp, not even the sensation of warm air leaving the vents.

Then the bunny-girl sat up.

She raised both gloved hands, gripped either side of the headpiece, and lifted.

The black rabbit-ear shell came free.

What was revealed beneath was not a face. It was another smooth black surface. She continued without pause — reached behind, found the zipper at the back of the kigurumi suit, and peeled the whole garment away like shed skin. Beneath it was a flesh-toned full-coverage bodysuit. She stripped that off too, efficiently.

Lin Yuan stopped breathing.

What sat before him was a doll. Solid black latex, head to toe.

Not a seam visible. No zipper. Smooth as if poured from a single continuous mould. The head was a featureless sphere — no eyes, no nose, no ears. Only at the mouth position: a round, O-shaped hole. Lin Yuan reached toward it with a trembling hand, pressed his fingers inside. The inner wall was latex too — and it was sealed. The hole didn't lead anywhere.

Which meant the person inside… could not speak. Could not breathe outside air.

The chest was unmistakably C-cup. He cupped it, squeezed — the latex yielded and rebounded, soft and uncannily lifelike. His gaze dropped. Between the thighs, a thin seam in the latex. He spread it apart with his fingers. Inside: a pink latex cunt, its walls rendered with almost obsessive precision, every fold and crease present and exact.

He turned the doll over.

The ass was smooth, perfectly rounded. Deep in the cleft, a small asterisk-shaped indentation — the rear hole.

Lin Yuan's mind was blank white noise.

Then he noticed something on the back of the doll's head.

A barcode.

He grabbed his phone, scanned it. The screen redirected to a clean app interface.

[Client Information] Name: Su Wan Photo: [A soft-smiling ID photo — long hair, delicate features] Product: Full-Body Correction Doll System (Beta) Notes: Client confirmed voluntary enrollment in product testing.

Lin Yuan stared at the photo.

His breathing stopped entirely.

Ms. Su.

His English teacher. The one who always smiled so gently, who liked to teach in black stockings and fitted pencil skirts, who stood at least five-foot-seven.

Now compressed inside this five-foot latex doll.

Something hit him — guilt and arousal tangled into a single unbearable current. He thought about English class. How many times he'd stolen glances when she leaned forward to write on the board, pencil skirt pulling tight over her ass. How her stocking-clad calves looked when she crossed her legs. The warmth in her voice.

And now. She was here. Inside this thing that could not speak, could not resist.

Lin Yuan carried the doll to the bed, laid her face-down, the smooth latex ass raised high. He spread the two rounded cheeks apart with both hands, exposing the soft pink opening. No preamble. He thrust his hips forward and buried himself inside.

Slick.

The latex walls closed around him — tight, warm, alive in a way that had no right to be.

“Ms. Su…” he breathed, driving into her, hands gripping the latex breasts from either side, kneading hard. “Did you know… every class I had with you… I was thinking about this…”

The doll gave no answer. She could give no answer. But when he said Ms. Su, the walls clenched — sudden and involuntary.

She could hear him.

She knew exactly who he was.

That knowledge sent a shock through him like voltage. He started driving harder. The latex ass rippled with each impact, the smooth black surface catching a wet sheen under the amber light. The doll's hips began to push back — subtle, unmistakable, angling to take each thrust deeper.

Smack. Smack. Smack. Smack.

Mmh… ah…

Lin Yuan came. Thick and deep, flooding the latex cunt. He collapsed back against the mattress, breathing ragged, ready to rest.

The doll moved.

She turned herself over. No features — but the O-shaped mouth aimed directly at him. She crawled forward, pressed her latex body against his chest, then swung one leg over and straddled his waist.

His cock, not yet fully soft, was guided by her hand. Lined up with that hole still leaking his cum. She sank down slowly.

Slick.

She began to move her hips.

The latex waist was pliant, fluid — rising and falling in a rhythm that built from slow to urgent. Her hands found her own breasts, gripping them, kneading hard, working the latex like she was feeling her way back to herself through touch. The O-shaped mouth stretched and contracted with the motion — no sound, but the way it opened and closed looked exactly like someone crying out in silence.

Insatiable.

Lin Yuan lay there and watched. His teacher. The woman who had once called roll in a classroom, who had handed back his marked-up essays. Now a latex doll, riding him with focused, unashamed want. Her hips moved faster. The inner thighs pulled taut with effort, the smooth black surface shone with something — moisture, or some simulation of it.

“Ms. Su…” he rasped. “You're that hungry?”

The doll's hips snapped into a full sprint.

Smack smack smack smack smack —!

Latex against his abdomen, dense and percussive. She leaned down, bringing the O-shaped mouth close to his ear. No breath came through. But Lin Yuan thought he could almost hear it anyway — muffled behind the latex, thick and formless and desperate.

Fifty minutes remained until the safe wear limit expired.

And she had only just started.

Chapter 2 - A Little Story from the Rooftop

Archived Version

Right at the moment Lin Yuan was about to come, the doll lifted her hips.

She rose off his cock with a soft pop, the latex cunt pulling away reluctantly, its lips parting slightly, the edges glazed with clear fluid. Before he could react, she had already turned around — the smooth black head orienting toward him.

The O-shaped mouth opened.

She leaned down, and the hole swallowed his head with mechanical precision.

Slick.

The latex inner walls closed around him immediately. The sensation was nothing like her cunt — tighter, denser, and covered in what felt like tiny ridges, like fine barbs, raking across every nerve cluster on the head of his cock. Lin Yuan sucked in a sharp breath. His cock lurched.

The doll began to move her head. Slowly.

Forward and back. Side to side. Small rotations worked in between. Her latex neck was impossibly pliant — capable of angles no human throat could manage. Each time she pressed down, the rim of the O-hole cinched tight around the base of his shaft. Each time she rose, that same rim dragged upward along the length, pulling sensation with it.

Lin Yuan watched that smooth black head bob between his thighs and felt something surge through him — strange, possessive, absolute. He reached down. Cupped the latex skull in both palms. And pressed down. Hard.

Glk.

He bottomed out.

The head of his cock hit the back of the cavity — no throat, no passage, just a thick wall of latex yielding and dimpling under the pressure. He felt the resistance. Felt the material concave around him.

The doll's whole body went rigid.

Then started shaking.

One hand clamped onto her own latex breast, kneading frantically, fingertips sinking into the soft material until the indentations held. The other hand reached behind her, found the slightly parted latex slit, and pushed two fingers inside. She started working them in and out — fast.

Squelch. Squelch. Squelch.

The sound filled the room.

Lin Yuan knew — inside that doll, Ms. Su's eyes were rolling back right now.

The thought detonated something in him. He gripped the latex head and started thrusting up, fucking that impossibly tight O-hole with purpose. Every thrust bottomed out. Every thrust made the doll's whole body shudder.

Slick, slick, slick —

The ridged inner walls raked the length of him with each pass. His breathing fractured. His hips moved faster. The doll matched his rhythm — head bobbing to meet him, the hand buried in her own cunt blurring with speed.

Faster — faster — faster —!

Lin Yuan came first.

It hit in waves, thick and heavy, flooding the latex mouth-cavity to the back. The doll's body jackknifed — latex thighs pulled taut, the hand still squeezing her breast went white-knuckled. She kept trembling. Continuously, sustained — like the woman inside her was cresting at the exact same moment.

Several seconds passed.

The doll went slack.

She drew off him slowly, the O-hole's rim dragging upward one last time, white fluid brimming at the edge and spilling down the smooth black jaw in a thin rivulet. Then she crawled up beside him. Pressed the latex body against his side. Arms looped around his waist.

Lin Yuan pulled her in.

Smooth. Cool. But carrying a faint residual warmth from everything that had just happened.

They lay there like that — and slept.

Morning light slid in through a gap in the curtains.

Lin Yuan woke to an empty bed.

The black latex doll was gone. The sheets held a few damp patches and the pressed impression of a body. He sat up. Sat there for ten minutes doing nothing. Then slowly put his clothes on and headed to school.

Third period. English.

When the classroom door opened and Su Wan walked in, Lin Yuan's heart nearly came out his throat.

She looked exactly as she always did — hair down, white blouse, black blazer. But today was different.

The pencil skirt was shockingly short. As she walked toward the lectern, the hem barely cleared the top of her thighs. Below it: pure black stockings, encasing both legs to the ankle, paired with narrow-toed black heels with at least eight centimetres of stiletto. When she bent to set down her lesson materials, Lin Yuan could see all the way up — the lace trim of black underwear.

Every male student in the room was pretending not to look.

Ms. Su seemed entirely unaware. She began the lesson, voice as measured and gentle as always. But when she moved through the aisle during instruction, passing Lin Yuan's desk —

He reached out.

Fingertips trailed lightly across the back of her stocking-covered calf.

A single instant of contact.

Ms. Su's step faltered. She turned her head and looked at him.

The look was complicated. Embarrassed. Reproachful. And underneath those, something else — a thread of concession.

She said nothing. Continued the lesson.

When the bell rang, Ms. Su packed her materials and walked directly to Lin Yuan's desk.

“Rooftop,” she said, quietly. Then walked out.

Lin Yuan followed.

The door to the rooftop terrace was always kept locked. Today it was ajar. He pushed through and found her standing in the shadow of the stairwell.

She heard him enter. Turned. Pushed the iron door shut behind him and locked it.

Click.

The bolt catching echoed in the narrow space.

Then Ms. Su began unbuttoning her blouse.

One. Two. Three.

She drew the front panels apart, exposing the black lace bra beneath. Then she gripped the bottom of the bra and pulled it down.

Both breasts fell free.

Milk-pale skin catching the dim light softly. Nipples light pink, already stiffening.

Lin Yuan stood there.

“Come here,” Ms. Su said. Her cheeks were flushed deep red. She'd turned her face aside and wouldn't look at him directly. Her hair slid across her shoulder with the movement. “But the thing about me being — that filthy black latex doll. Don't tell anyone.”

She bit her lower lip. Her voice dropped further. “My body… you can use it however you want.”

Lin Yuan smiled.

He stepped forward, put both arms around her waist, and buried his face in her chest. Nose tracing over the left nipple. Then the right. The contact hardened them quickly, two small, taut points rising against his skin.

Ms. Su's breathing shifted. One hand found the railing beside her and gripped it. The other moved without thinking and closed in his hair.

Lin Yuan moved around to her back.

His hands began at the backs of her thighs, following the texture of black stocking upward. Fingertips crossing the soft hollow behind her knee. The inner thigh. Then — slowly — approaching the crease between her legs.

His touch pushed the pencil skirt higher as his hands travelled up, the fabric eventually failing to cover the curve of her ass, two rounds of stocking-wrapped flesh spilling into view. He saw it then — black lace underwear underneath, and more surprisingly: the crotch panel of the stockings was cut away, an oval opening in the weave that left the lace trim of her underwear directly exposed.

He pressed his palm against her through the fabric. Soft. Yielding. Already warm.

The other hand slid under her arm, around to the front, and took hold of her bare breast. Thumb circling the nipple.

“Mmh…” A suppressed sound escaped her.

Her legs started going. The stiletto heels clicked an unsteady rhythm against the floor. Lin Yuan pressed in closer, cock hard and straining in his trousers, grinding into the cleft of her stockinged ass.

Hiss. Hiss. Hiss.

Fabric against nylon.

After a few minutes, Ms. Su said between breaths: “If you're going to put it in… just do it… class starts soon…”

Lin Yuan didn't wait any longer.

He unzipped his trousers and freed his cock, aching, and full. He hooked two fingers into the side of her underwear and pulled the lace panel aside — and there, beneath the oval gap in the stockings, was the slick-flushed entrance to her cunt, glistening and open.

He pushed in.

Slick.

Hot. Tight. Soaking.

He plastered his body against her back, arms reaching around to the front, a breast filling each palm, and he gripped hard. His hips found their rhythm — pulling back, driving forward, cock working deep into that warm clutching heat.

Smack. Smack. Smack. Smack.

Ms. Su's one hand clenched the railing in a white-knuckled grip. The other pressed hard over her own mouth. Tiny muffled sounds leaked between her fingers anyway.

Mmh… nngh… ah…

He drove faster.

He was close — right at the edge — when Ms. Su suddenly said: “Wait.”

She pulled free of his arms and turned around.

Then sank to her knees.

She gathered her hair and swept it up, coiling it against the back of her head with practiced efficiency, securing it with a hair tie produced from nowhere. Then she looked up, opened her mouth, and took his cock — still slick from inside her — all the way down.

Deep throat.

Without a moment's effort.

Her mouth was warm and wet, tongue winding along the underside with precise, unhurried pressure, suction calibrated perfectly. Lin Yuan held the back of her head and looked down at her — brow lightly furrowed, eyes half-closed, expression of someone doing something that mattered.

Several minutes.

Lin Yuan's hips drove forward.

Thick ropes of cum pulsed straight into the back of her throat.

She didn't pull off.

She stayed there, holding him in her mouth while his cock worked through its last pulses, then drew back slowly and deliberately. Then she tilted her face up toward him.

And opened wide.

Her tongue extended.

Her mouth was flooded white — viscous, pooling, a few trails catching the corner of her lips.

Her eyes rolled up until most of the iris disappeared. Both hands rose to frame her face in a V-sign on each cheek — an exaggerated, deliberate ahegao expression, the kind that belongs on a screen, not in a school stairwell.

She held it for three seconds.

Then the expression dropped. She closed her mouth. Her throat moved.

Gulp.

All of it, swallowed.

She stood, dabbed at the corner of her mouth with one finger, the flush in her cheeks still warm. “We're going to be late for next period,” she said softly, and began smoothing her skirt back into place.

As if nothing had happened at all.

Chapter 3 - Mysterious Delivery

After their time in the stairwell, Ms. Su asked for his home address before she left.

“Sending you something,” she said, the flush still in her cheeks, heels clicking a rapid staccato on the concrete floor, her figure disappearing around the bend of the staircase before he could ask anything.

Lin Yuan didn't think much of it.

Until Saturday afternoon, when the doorbell rang.

The delivery man handed over a small cardboard box, surprisingly light. Lin Yuan signed for it, carried it to his room, and ran a box cutter along the tape.

Inside: white foam packing paper, layered thick.

He peeled it back, one sheet at a time. Beneath all of it, the box held exactly two things: a small hard-paper case about the size of a mug, and — Ms. Su's work ID badge.

The laminated card. Her ID photo smiling gently up at him. Name printed in clean type: Su Wan. Title: English Teacher.

His heartbeat skipped.

He picked up the small box first, opened it.

Inside lay a doll.

Anime catgirl design. Entirely pink. The material looked like transparent silicone — impossibly soft. He prodded it with a finger. It gave like jello, dimpling immediately under the pressure, then recovering the instant he pulled away.

It was small. About the size of his palm. Two grape-sized protrusions on the chest, slightly raised, the same pale pink. The arms were strange — only the upper arms were present, two small stubby cylinders, no forearms, no hands. The lower half was stranger still: no legs at all, just two rounded spheres forming the hips, with a narrow cleft between them.

Lin Yuan stared at the cleft for several seconds.

He had a pretty good idea what the transparent little thing was designed for.

What he couldn't understand was why Ms. Su had sent it to him.

He dug through the rest of the box — looked for a note, an instruction sheet, anything explanatory. Nothing. Just foam paper and the ID badge.

The badge.

He held it next to the pink translucent doll.

A terrible hypothesis took shape.

No. Impossible.

The black latex doll had been insane enough — but at least it was human-shaped. You could stretch your imagination and picture someone being sealed inside it. But this thing was a masturbation sleeve. A palm-sized, transparent, silicone sleeve.

His fingers were trembling as he turned the doll over.

At the centre of the back, near the base of the hips: a small barcode.

He scanned it.

The familiar app interface loaded.

[Client Information] Name: Su Wan Photo: [Soft-smiling ID photo — long hair, delicate features] Product: Pleasure Sleeve Set (Pink Transparent Edition) Notes: Client confirmed voluntary purchase and use of this product. Product function: compresses client into the form of a masturbation sleeve. Virtually undetectable without prior knowledge. Current wear time: 2 hours Times inserted: 0

Lin Yuan stared at the screen. His mouth was open. Nothing came out.

He looked at the doll. Then the phone. Then the doll again.

“I'll give you the latex doll last time — that was at least one-fifty centimetres, you could rationalize it…” he murmured, his voice gone dry. “But this… this is a transparent sleeve.”

The pink, translucent doll trembled in his hand.

Faintly — but he felt it.

The soft silicone body shivered, the way jello shudders when someone bumps the table. A few small pulses.

Lin Yuan went very still.

He extended his right index finger. Slowly, tentatively — pressed it toward the narrow cleft between the rounded hips.

The moment his fingertip made contact with the opening, the doll shivered again.

He pushed his finger in.

Slick.

The entrance was tight, but the material gave way with almost no resistance, stretching around him with uncanny softness. What made it stranger still was the transparency — Lin Yuan could see his own finger inside.

Pink silicone walls wrapped around him, visibly yielding as he pushed deeper, visibly tightening as he drew back. The inner surface clung. Through the semi-translucent material, he could make out the outline of his own knuckle.

“Since you're transparent…” His voice came out unsteady. “How exactly did you fit yourself into a sleeve, Ms. Su?”

The inner cavity clenched.

Sudden, vise-tight, almost painful around his finger.

He understood.

This doll — this sleeve — Ms. Su, inside it, could hear everything he said. And she was responding to it.

Lin Yuan swallowed.

He pushed his trousers down. His cock was already rigid and aching. He held the pink translucent sleeve in his left hand, steadied himself with his right, lined up with the narrow cleft, and pushed forward. Slowly.

The opening stretched around him.

The moment his head pressed through, he could see it through the transparent walls — the crown of his cock pushing a visible dome into the inner cavity, the silicone fabric going taut and thin over the shape of him. Pink walls closed in from all sides. Soft, wet, elastic in a way that felt nothing like a manufactured object.

He kept pushing.

He sank in to the base.

The sleeve was so small that his cock filled nearly the entire interior cavity. Through the transparent shell he could see everything — the silicone walls stretched thin and pale around him, pressed against every contour, every vein rendered visible through that translucent pink skin.

He started to move.

Right hand wrapped around the doll's body, stroking up and down. His cock worked through the tight transparent channel, the material stretching open on every thrust, contracting on every pull.

Squelch. Squelch. Squelch.

Wet. The inner walls were wet — whether that was silicone lubrication or something the person inside was producing, Lin Yuan couldn't say.

His left hand hadn't been idle. He caught both grape-sized chest protrusions between thumb and forefinger and began to knead.

Soft.

Absurdly, impossibly soft.

Like actual grapes — they deformed completely under his fingers, then recovered the instant he let up.

The moment he squeezed, the inner cavity clenched again.

That sudden compression nearly sent him over the edge then and there.

“Ms. Su…” he breathed, stroking faster. “Are you… excited in there…?”

No answer — she couldn't answer. But the inner walls had started to move in rhythm now. Contracting and releasing, contracting and releasing, a slow deliberate pulse.

Lin Yuan's hand sped up.

Stroking faster. Gripping the small chest harder. The transparency let him see all of it — the path his cock carved through the cavity on each thrust, the shape the walls made as they stretched, and once, for just a moment, something that looked like movement in the very deepest part of the channel. A faint, internal writhing.

Faster — faster —!

He came.

Thick ropes of cum flooded into the transparent cavity. White fluid spread through the pink translucent material, pooling, flowing, rapidly filling most of the interior space.

The doll's body began to seize.

Small, rapid convulsions. The two grape-sized protrusions on the chest shook with the rest of the silicone body, the entire thing trembling like disturbed jello. The inner walls kept clenching — rhythmic, greedy, squeezing around him as though trying to draw out every last drop.

Lin Yuan slumped back in his chair.

His cock slid slowly free of the entrance, which was still brimming with white fluid.

He held the sleeve up and looked at it.

Through the transparent pink shell, white cum drifted and settled. And through that layer of liquid — through the material, in the deepest part of the cavity — something was moving. Faintly. Rhythmically.

Breathing.

Or maybe a heartbeat.

He picked up his phone. Found the app. Looked at the counter.

Times inserted had changed from 0 to 1.

Chapter 4 - Don't use it in class, oh my goodness!

Archived Version

Inspired by Yu Tashiro: illust/129144583

That weekend, Lin Yuan barely left his room.

The pink translucent catgirl sleeve became his only occupation. Whether sitting at his desk watching videos or lying flat on the bed staring at nothing, he kept his cock tucked inside that soft jello-like cavity. Two full days. The transparent silicone walls were worked open again and again, the interior filling, drying, then being flooded with fresh white slick until the material had grown almost cloudy with it.

Monday morning, Lin Yuan — moved by some impulse he didn't entirely examine — tucked the doll into his school bag and went to class.

Sitting at his desk, he found himself turning over a genuine logistical question: if Ms. Su is currently lying in my bag, then who exactly is going to teach English today?

Third period bell rang. The person who came through the door was a middle-aged man Lin Yuan had never seen before.

“Morning, everyone. Ms. Su is out on medical leave for the time being. I'll be covering her classes.”

Lin Yuan's hand slipped beneath the desk and found the small, hard shape through the fabric of his bag. His mouth curved.

Medical leave. Sure. Two days of getting fucked senseless. She'd earned a rest.

Halfway through the lesson, he raised his hand and asked to use the bathroom. Phone in one pocket, pink translucent sleeve in the other, he slipped down the corridor and into the stall at the far end.

Door shut. Lock turned.

He pulled out his phone first, scanned the barcode on the doll's back.

[Product Real-Time Status] Client name: Su Wan Current wear time: 51 hours Times inserted: 33 Notes: Product has adapted to high-intensity use.

Lin Yuan pushed his trousers down and freed his cock, already hard. He gripped the pink sleeve, pressed the head of his cock against the indented cleft.

Slick —

The moment he pushed in, his expression changed.

Tight.

Compared to the easy give of the weekend, the inner cavity now gripped him with almost punishing force. The transparent silicone walls seized around his head, and as he pressed deeper, the material stretched so thin it nearly lost definition — a clinging, sucking pressure that made his scalp prickle.

He leaned in close to the little cat ears and kept his voice low.

“So Ms. Su likes having class with me here better… Getting fucked at school feels different, does it?”

Mmmmh…

The translucent sleeve shivered in his hand. A tremor coming from somewhere deep in the silicone.

He started to move — right hand working the sleeve up and down along his cock, building speed. Through the pink transparent material he could see exactly what he was doing to the walls inside.

“Are you excited? Being back at school like this?”

He grinned. His hand moved faster.

“Sitting in my bag listening to the substitute lecture — while my cock goes in and out of your little cunt… Ms. Su, you really are just a slutty little sleeve, aren't you?”

Smack. Smack. Smack. Smack —!

The shivering became convulsions.

The small body thrashed in his grip, the inner walls clamping and releasing in rapid, uncontrolled spasms, squeezing his cock with frantic intensity. The sensation hit Lin Yuan like a fist — he let out a choked grunt, hips snapping forward, and came.

Pulse. Pulse. Pulse. Pulse —!

Thick white flooded the entire transparent cavity in a single sustained rush — so much that it immediately began spilling back out from the entrance.

The doll didn't stop.

It writhed in his hand like a fish dropped on dry land — twisting, jerking, throwing itself in every direction. Ms. Su had clearly lost all control of whatever passed for a climax in there, and the convulsing silicone body flung the overflow of cum in scattered droplets across the stall walls.

White fluid clung to the door panel. Ran in slow tracks toward the floor.

This continued through Friday night.

The same delivery person — black clothes, sunglasses, no words — knocked on Lin Yuan's door and collected the sleeve, now clouded and heavy with a week's worth of use.

Monday morning.

Lin Yuan walked into the classroom and heard it before he saw her: the familiar sharp rhythm of heels in the corridor.

Ms. Su came through the door in a deep purple pencil skirt, long legs moving in alternation inside black stockings. She set her materials down on the lectern, and there was something different in her face — a warmth in her complexion that hadn't been there before, a colour that suited her. When her eyes crossed the room and found Lin Yuan, the corner of her mouth moved. Barely. Just enough.

“Good morning, everyone. I'm back. Let's begin.”

Chapter 5 - Start and Stop

Archived Version

Days passed. Lin Yuan and Ms. Su maintained a strange equilibrium.

At school, she was the strict English teacher, he was an ordinary student. Occasionally, on the empty rooftop, she would call him up, lift her skirt and let him “review his lessons” — that was the word she used for it. Her reward.

Then one morning during the break between terms, another delivery arrived.

This box was large. Lin Yuan had to use both arms to get it back to his room. He cut through the outer cardboard to find a thick layer of foam packing paper. Sitting on top of the foam: a work ID badge. Ms. Su's.

Something dropped in his chest.

He lifted the foam away.

Inside lay a pink translucent silicone doll.

She was sealed in a clear plastic bag, face-up, legs bent and parted, body curled to fit the dimensions of the box. The material looked like the sleeve from before — soft as jello. Lin Yuan lifted her out, peeled the bag open, and laid her on the bed.

The doll was approximately 170 centimetres. Proportioned like a real body.

She had a pair of C-cup breasts, translucent pink, cool to the touch and yielding like two enormous puddings. Long legs, inner thighs soft enough to push apart without any resistance. The ass was two rounded masses of transparent silicone, with a dimpled opening between them — the rear hole.

The face had features, also translucent pink. The mouth was fixed open in a permanent O, wide enough that he could see inside — a transparent oral cavity, and a tongue. That jello tongue trembled faintly when he looked at it. He reached over and pushed it to the lip line with one finger.

He pressed his hand into the doll's mouth.

Glk.

His arm forced the O wider, and through the transparent skin he could watch his hand disappear down the throat. Bottom of the cavity.

On the doll's lower abdomen, a black barcode was printed into the silicone. Below it, between the thighs, the soft folds of a cunt — spread apart, the inner walls showed the same pink translucent material throughout.

The whole thing had the inert quality of a manufactured object. No sense of life.

But the longer Lin Yuan looked, the more he recognized the face — that bone structure, those proportions —

He picked up his phone and scanned the barcode.

Lin Yuan had long since stopped trying to work out how Ms. Su “entered” these things. He looked to the bottom of the box. A few garments were folded there: black stockings, a white blouse, a deep purple pencil skirt — exactly what she wore to school. And her teacher ID badge.

He dressed the doll one piece at a time.

Black stockings drawn up over those transparent legs. The blouse buttoned closed. Pencil skirt pulled up to the waist. The ID badge clipped to her chest.

What lay on the bed now was Ms. Su in every respect, except that she was made of pink translucent silicone.

Lin Yuan lay back and pulled the doll face-to-face on top of him.

His hands found the curve of her ass through the pencil skirt, fingers sinking into the silicone. His cock hardened quickly, pressing against her abdomen through the fabric. After a while, he pushed the doll's stockinged legs apart.

She let him arrange her however he wanted. He knew who was inside.

He pressed slowly into the soft jello folds of her cunt.

Slick —

The smoothness was unreasonable.

The moment he bottomed out, a familiar vibration rose from somewhere deep in the inner cavity.

Then the soft body in his arms changed. The material didn't stiffen exactly — it gathered, developing a kind of interior resistance. Support. And then the body moved on its own.

The doll pushed herself upright. Her hips began to roll, back and forth, without any prompting.

So that's how it works. Insertion turns her on. Withdrawal shuts her off.

Once activated, she seemed unable to speak. She simply brought that O-shaped mouth toward his and pressed it against his lips.

A jello tongue entered his mouth. Cool, smooth, frictionless. Lin Yuan pushed back, working his own tongue into the transparent oral cavity, moving it around inside.

Wet sounds. Slick pressure.

At the same time, the doll's hands began to unbutton her blouse, exposing the transparent breasts. One hand braced her body. The other moved to her own chest.

Every time her fingers grazed her nipples, Lin Yuan felt the inner walls of her cunt cinch tight around him.

Her fingers found his nipples too sometimes, pinching gently.

Neither of them stopped moving their hips. Neither of them stopped the slow, deep kiss.

After a while the doll had straightened fully upright, both hands kneading her own jello breasts, hips working in tight rapid circles like something mechanical had taken over.

Lin Yuan thrust up to meet her.

Smack. Smack. Smack. Smack.

The transparent cunt deformed visibly around his cock with each drive — the silicone walls pressing out, the full length of him visible through the skin on every stroke.

He grunted low and came.

Pulse — pulse — pulse —!

Thick white filled the translucent cavity instantly.

In the moment of orgasm, Lin Yuan reflexively pulled out.

The instant his head cleared the entrance —

The doll's body lost all coherence and fell backward, hitting the bed with a dull thud, completely inert.

The cum inside her began to seep slowly out.

Lin Yuan startled, scrambled forward, and pushed back in.

Hmmm…

The vibration returned.

The body beneath him took a breath — literally, visibly, the chest beginning to rise and fall again. Lin Yuan lay down on top of her, buried his face in her transparent breasts, and closed his mouth around one nipple.

Wet sounds. Cool against his tongue.

The jello nipple yielded completely in his mouth, that cool translucent taste mixing with the warmth leaking from below.

He said, muffled against her chest:

“Ms. Su… you can't go offline again.”

He stayed inside her. Lay pressed against the doll's body. Felt her chest rise and fall. Felt the slow, soft contractions of the inner walls below.

This is fine. As long as I stay inside her, she stays.

For the entire holiday, Lin Yuan lived with the pink, translucent doll.

When he got bored partway through his homework, he would open the wardrobe door. She was curled inside — bare because he'd stopped bothering with clothes at some point, and it saved time. He'd gotten into the habit of keeping her there without anything on, the wardrobe a convenient place to store her between uses while maintaining close access.

He carried her to his desk chair, sat down, and settled the doll into his lap facing him. The position left her cunt lined up directly with his crotch.

He unzipped his trousers and pushed his half-hard cock through the soft jello folds.

Hmmm…

A faint vibration from somewhere deep inside.

The soft body in his arms gathered itself. The doll — Ms. Su, compressed and trapped inside — turned her head, gave him one look, then turned back to face the stack of math worksheets sitting on the desk.

She shook her head faintly. Her transparent fingers reached out and picked up the mechanical pencil. She began marking the papers with methodical precision.

Lin Yuan held her warm body against him, cock moving in slow, shallow thrusts. He leaned toward the transparent ear.

“Ms. Su. I really don't understand this problem.”

She ignored him. Pencil moving — crosses through wrong answers, circles around mistakes, correct working filled in below.

Lin Yuan slid one hand under her arm and caught a cool, soft nipple between two fingers. Rolled it slowly.

Slick sounds. Growing.

He kept the thrusts shallow and even — small upward movements, enough to feel good, not so much that her hand would shake. He was careful about that.

The transparent breast deformed in his palm. He could see the outline of his fingers pressing through the material from the other side. The doll's body shivered once, lightly. The hand holding the pencil didn't pause.

“You're so focused, Ms. Su…”

He dragged his tongue along the translucent curve of her ear.

She finished the last problem. Set the pencil down. Then leaned back into his chest and let him accelerate — let him drive deep until he poured everything into her.

More often it was in bed.

Late at night, Lin Yuan would tuck the doll under the blanket, lie with his back to her, and slide his cock into the O-shaped mouth.

Mmh…

A muffled sound from somewhere in the throat. Then vibration from inside.

Once she activated, Lin Yuan just lay there comfortably and let that cool jello tongue do its work.

Wet. Slow. Relentless.

He'd lift the blanket sometimes and look back.

The translucent face was buried in his lap, the oral cavity distended around him, the shape of his head visible all the way down to the back of the throat. That view made him come faster every time.

After each finish, he always remembered to move his cock back to her cunt.

Push in — and the doll in his arms would open her eyes again, and reach up and hold him.

One boy, one doll. Arms around each other. Asleep.

He woke a few times each night and always reached down first to check that he was still inside her. Only once confirmed would he settle back. Because if it slipped free, his teacher would revert to inert pink silicone, and he didn't allow that.

He had decided he didn't accept that.

The summer passed entirely this way.

Two weeks before the start of term, the doorbell rang.

Lin Yuan opened the door. A middle-aged man in a black uniform stood in the hallway, a delivery company logo on his chest.

“Good afternoon. I'm here to collect the product.”

His face gave nothing.

Lin Yuan stood still for a moment. Then stepped aside without a word.

The man walked directly to the bedroom. He looked at the pink translucent doll on the bed — white blouse, black stockings, cock still inside her, unit still active.

The doll raised her head. Looked at the man in black. Looked at Lin Yuan.

The man produced foam packing paper from the large case he'd brought and began removing the doll's clothing with practiced efficiency. Stockings, blouse, pencil skirt, ID badge — all folded and placed into a separate bag.

Then he wrapped his hand around the doll's ankle and gently drew Lin Yuan's cock free.

Pop.

Fluid ran from the entrance, mixing with what had been inside.

The instant contact broke, the doll's body went click — all structure gone, collapsing into motionless silicone.

The man wrapped the bare doll in foam, fitted her into the large cardboard box, sealed it with tape.

The whole process took under five minutes.

“Thank you for using our product.”

He shouldered the box, gave Lin Yuan a single nod, and left.

The door clicked shut.

The bedroom held only an empty bed and a few translucent traces drying on the sheets.

Lin Yuan stood there for a long time.

Then he walked to his desk and sat down. He opened the maths workbook — the one marked up cover to cover with corrections that weren't his.

On the blank space at the bottom of the final page, in pencil, in handwriting that looked like his but was neater than his had ever been:

See you when term starts.

He read it for a while.

Then he closed the workbook.

Chapter 6 - Dolls and Back Alleys

Archived Version

Lin Yuan almost arrived late on the first week of the new term.

Friday morning, he sprinted into the building with the bell practically already ringing — and found someone blocking the classroom doorway.

“Um — classmate — you're late today — sorry — sorry, could you sign here — I'm really sorry to bother you, I have duty today —”

The voice was soft and small, like a kitten.

Lin Yuan looked up. A girl in round-frame glasses. About 162 centimetres, skin pale as a peeled egg, sweet-faced, hair cut neatly to the shoulder. White blouse straining over a full C-cup chest. Deep blue school skirt. White over-the-knee socks.

Chen Yuwei. Class's resident wallflower.

Last semester, a boy from the adjacent class had confessed to her. She'd gone red as a tomato and literally turned and fled, then spent an entire month routing around him in the corridors.

Lin Yuan rubbed the back of his head, mildly embarrassed.

“I'm the one who messed up — you don't need to apologize.”

He took the register and signed it. From the corner of his eye, he caught Chen Yuwei's hands clenching tight in her skirt hem, her ears flushed pink.

Back at his seat, the image lingered for a moment — those slender calves inside the white over-the-knee socks, and the anxious flickering gaze behind the round glasses.

Then coursework swallowed him whole.

During the long break, Lin Yuan went straight to the rooftop.

He pushed the iron door open. Ms. Su was already there waiting. Today she wore her standard ensemble: white blouse, deep purple pencil skirt, black stockings, heels.

Lin Yuan walked over and pulled her against him.

“Ms. Su… I almost got written up today.”

He pitched his voice to sound aggrieved, while his hand was already working up under the hem of her blouse, finding the bra clasp with practiced ease.

Ms. Su's face coloured, but she didn't stop him.

They settled against the water tank together, Lin Yuan burying his face in her open blouse, lips closing around one nipple. His other hand pushed the pencil skirt up to the top of her thigh, fingers locating the gap in the stocking crotch — the one that had been specially modified for convenient access.

Tear.

The black lace underwear pulled aside. The wet entrance open to the air.

Lin Yuan freed his cock and pressed slowly inside.

Slick.

“Mm… gently…”

Ms. Su covered her mouth. Her other arm pulled him close.

They sat face-to-face like that, moving in small, careful arcs. Lin Yuan talked while he thrust.

“That girl on duty today — Chen Yuwei. You know her? Frighteningly timid. But her legs are quite pale, with those white socks…”

“Why are you… paying attention to her… ah…”

Ms. Su breathed against his ear. Her hips were moving with increasing purpose.

“Just mentioning it. Are you jealous, Ms. Su?”

He sped up. His cock worked through the gap in the stockings, the wet sounds growing louder.

Smack. Smack. Smack. Smack.

Ms. Su stopped talking. She bit down on his shoulder and matched every stroke with her hips.

Not long after, they both shuddered at once.

“Coming — Ms. Su —”

Pulse — pulse — pulse —

Through the condom, scalding cum flooded deep inside. Ms. Su went slack against him, both of them staying joined, breathing.

After a few minutes, she recovered enough to crouch down, carefully drawing him out and removing the condom.

Then — before Lin Yuan could register what was happening — she opened her mouth and took his cock in, still streaked with residue.

Wet sounds. Slow and thorough.

Like working through a popsicle. Her tongue moved over every centimetre from head to base, cleaning him completely.

Lin Yuan looked down and felt something crooked and deeply satisfied settle in his chest.

Half a year ago, she was so gentle. So composed. And now.

When she finished, she stood and straightened her clothes, the flush in her face not yet faded.

Before she left, she reached into her bag and pressed three things into his palm.

A small silver key.

A black room card.

A folded piece of paper.

“This weekend… if you have nothing to do…”

She said it and walked away quickly.

Lin Yuan unfolded the paper.

One side bore a familiar logo — the same one that had been printed on the box the pink doll arrived in.

He flipped it over.

An address: 28 Xinghe Road, Building B, Room 1703.

He stared at it for a few seconds, folded it, and put it in his pocket. His thumb moved over the key and the room card.

This weekend.

The cold wind moved through the alley late that Saturday night, the streetlight fractured by high walls into broken pieces across the ground.

Lin Yuan walked to the end of the alley with the room card and the small logo-printed slip. At the far end stood a rusted horizontal pipe. Below it, something bundled in black cloth trembled faintly, the familiar logo on the wrapping catching the dim light.

He stepped forward and tore the cloth away.

His pupils contracted slightly.

What was exposed was a jet-black latex doll, surface gleaming with an industrial sheen.

The shape was identical to the kigurumi Ms. Su had been wearing at the convention — but this was something more extreme. No zipper. No seam anywhere. From crown to sole, every centimetre sealed under dense matte-black latex. The head was a smooth sphere with no features at all, not even a ventilation hole at the mouth. The crotch and the rounded ass were completely unbroken surface — nothing but pure cold latex curves.

The doll's wrists were cuffed in steel handcuffs, arms raised and locked to the pipe above. The 162-centimeter body hung without the strength to hold itself upright, back against the wall, legs splayed, knees on the ground.

Even completely sealed, Lin Yuan could see the chest heaving — the motion of breathing, but with the latex surface fully closed, no air passed through in either direction. Alongside the breathing, the body was producing small recurring convulsions, shivers moving through the latex at irregular intervals, as though something beneath the surface was perpetually on the edge of overload.

It looked like an object. Inert. Industrial. A dead thing. The only evidence of a living person inside was the chest's movement — breathing with motion but no airflow — and those involuntary tremors that passed through the body for no visible reason.

Lin Yuan crouched down. His eyes moved over the full C-cup chest.

“Going all out tonight, Ms. Su.”

A quiet laugh. His hands didn't reach for the key. Instead, with something that was half curiosity and half deliberate cruelty, he pressed both palms flat against the black latex breasts.

Squeak —

The moment contact was made, the doll's head — which had been hanging limp — snapped violently back.

It was a response that exceeded any normal physiological limit. The body jackknifed forward at the waist, the legs that had been knelt on the ground flailing, and then the entire body convulsed in a sustained spasm, as though current had been run through it. The latex surface reflected the tension in the dim light.

Lin Yuan didn't release his grip. He slowed down instead — deliberate, unhurried, kneading the warm masses of latex with systematic malice. Through the material, he could feel the body inside thrashing continuously. With no opening for sound to escape, there was only the percussion of the body hitting the wall and the metal cuffs straining against the pipe.

Clang. Clang —

The pleasure seemed to have built past whatever the doll could process. The body kept shifting position under his hands — pressing forward into his palms, then lurching backward when the sensation became too much to absorb. The small latex-sealed fists clenched tight in the cuffs, pulling and working against the steel, but the latex was too tough to mark; the rings left no trace on the black surface.

“You're so sensitive tonight. That was already the second time.”

Lin Yuan watched the black mass of the doll with a look of quiet amusement. Under his continued working, the body moved through wave after wave of shuddering — until a final full-body spasm that lasted over ten seconds subsided, and then the doll went entirely slack, hanging like a puppet with cut strings. Only the chest's continued heaving confirmed it had not simply ceased.

He finally let go and opened the luggage case beside him.

Inside, a sheet of paper:

Deliver the doll to the hotel room matching the card.

He took out the key and fit it into the lock.

Click.

The cuffs sprung open. The doll's arms dropped to either side, no strength left in them; they'd been raised too long.

Lin Yuan spread the case open fully and slid one arm under the doll's back, the other under her knees. But the moment he gathered her against him, the contact — however gentle — registered as fresh stimulation.

Shudder —

The body arched again in his arms, limbs twitching against his chest, and then this last surge of sensation finished the job; she went entirely limp, unconscious in all but name.

He waited until the trembling slowed. Then he folded the body carefully, the way one might handle a delicate and expensive object — knees drawn up to the chest, hands positioned behind.

Ziiiip —

The case closed around the sealed black latex form.

Lin Yuan extended the handle. The wheels turned against the silent street.

Rumble. Rumble.

He walked toward the hotel lights ahead, pulling the case at an easy pace. Inside it, the black object rocked faintly with each step, making no sound at all.

Chapter 7 - Pulling the Plug in a Hotel

Archived Version

Lin Yuan dragged the luggage case into the hotel room. The lock engaging sounded very loud in the quiet. He lifted the heavy, fully sealed black latex body onto the bed and laid her flat.

The figure gleamed under the lights with a cold, industrial sheen. Lin Yuan walked around her once, frowning. The latex suit had no openings anywhere — not a seam, not a slit, not even the usual holes for bodily functions.

“Ms. Su, there's nowhere to put it. You haven't left me a single opening.”

He leaned down toward the featureless, smooth head and asked, genuinely puzzled.

The doll seemed to understand. The entire black latex body shuddered violently, then dropped back into dead stillness. Lin Yuan gave up trying to work it out and leaned against the headboard, pulling the heavy figure into his arms. His chest pressed against the black latex back. The doll's head lolled back and came to rest on his shoulder.

His hands began to move across her body. Through the taut latex, he could feel the astonishing heat of the flesh underneath. Every time his fingers passed over the latex breasts, the smooth abdomen, or the inner thighs, the body in his arms convulsed in sharp recurring bursts — like something was building inside with nowhere to go.

When he pressed his palm flat against the smooth crotch and ground his hand over the sealed area where her sex should have been, the reaction peaked.

Squeak — squeak —

Latex on latex. The doll's ass ground frantically against his crotch, the friction enormous even through clothing. His cock went painfully hard inside his trousers, working itself toward the edge just from the grinding of that sealed black body.

Then the doorbell rang.

Lin Yuan flinched, yanked the blanket over the still-convulsing doll, straightened his clothes, and went to the door.

He opened it and went completely still.

Ms. Su stood in the hallway. Pencil skirt. Black stockings. Heels. Her full professional composure.

“Ms. Su? If you're out here, then who's in the doll?”

She smiled and didn't answer. She wheeled her luggage case inside and produced a student ID card from her bag, handing it to him.

Lin Yuan looked at the photo. The sweet-faced girl with the long hair. Small and pale.

The girl who'd stopped him at the classroom door on Friday morning.

“Oh — it's her?!”

He shut the door and went to the bed. He grabbed his phone, found the barcode on the back of the doll's head, and scanned it.

[Name: [redacted]][Product: Full-Body Correction Doll Set (Standard Edition)][Notes: Client confirmed voluntary purchase and wear of company product. Product function: corrects and adjusts client's body contours to achieve desired figure.][Current wear time: 5 hours]

The timid girl. White over-the-knee socks. 162 centimetres. Sweet face. Hiding inside a fully sealed latex shell like this. Lin Yuan's cock swelled to its limit.

Ms. Su was pulling her luggage case toward the bathroom, a small bottle of clear liquid in her hand.

“Don't let the shy act fool you. Her appetite is substantial. She's new to the company's products, but she took to them.”

She began applying the liquid evenly to three specific areas of the doll's exterior — where the mouth, vagina, and rear entrance would be. It dried almost immediately. The smooth black latex in those areas began to lift and peel like dead skin, three small square outlines rising to the surface.

“Come help.”

Lin Yuan stepped forward. Following Ms. Su's lead, he pinched one corner of the panel at the crotch. Ms. Su pressed the doll's head down with one hand, gripped the mouth panel with the other, and pulled sharply upward.

Slick —!

A dense, fleshy sound.

A latex plug the diameter of a daikon radish — surface covered in raised nodules — was wrenched free from what had been the smooth mouth position. The sealed hole it vacated gaped wide before slowly contracting, revealing the latex oral cavity sealed behind it.

Ah — mmh —

Even without a sound opening, the doll's body went into full convulsion from the extraction alone. The hips nearly folded backward at an impossible angle.

The plug continued to vibrate and writhe in Ms. Su's hand, its surface glazed with lubricant.

“Bigger than I expected. That's quite the choice for daily use.”

Ms. Su squeezed the thick latex rod, her tone conversational.

Lin Yuan's mouth had gone dry. He took hold of the remaining two panels — crotch and rear. The first few seconds of pulling produced nothing but the doll's escalating trembling, each extraction hole clinging with strong suction. He put his weight into it.

Smack —!

Slick — slick —

Two plugs even larger than the first came free simultaneously. The latex openings at the sex and rear gaped for a long moment before slowly drawing back to normal slit-size.

The doll hit a climax that moved through her entire body. All four limbs swept across the bed and then went limp.

“No wonder, she was coming from a single touch earlier. She's been packed like that the whole time.”

Lin Yuan stared at the two still-twitching latex rods, breathing hard.

Beside him, Ms. Su's expression remained composed. What neither of them noticed: the crotch of her underwear beneath the stockings had soaked through completely. A single drop of fluid traced the inside of her stocking seam and fell silently to the floor.

Ms. Su picked up all three latex rods, helped the doll upright, and guided her toward the bathroom.

“She's been out in that alley. I'll get her cleaned up.”

The bathroom door clicked shut.

Inside, Ms. Su lowered the still-faintly-convulsing doll into the empty tub. She worked efficiently — locating the hidden button at the base of each plug, pressing once. The three oversized inserts contracted back down to standard vibrator dimensions. Under her fingertips, as they shrank, she felt the residual warmth of the silicone. She remembered the size they'd been when she pulled them free. Her lower abdomen clenched with heat.

She set the three reduced units on the sink shelf and opened her own luggage case.

Inside: a full-coverage latex suit, identical in design to the one the doll was wearing. Same matte black. Same seamless surface.

Ms. Su removed her pencil skirt and blouse. She stood bare in the bathroom's warm light and picked up the suit.

The only entry point was at the crotch — a single small opening, sized for a penis. The one and only way in or out.

She crouched, spread the elastic latex entrance with both hands, aligned her head with the opening, and began forcing herself inside.

The interior was tight and slick. She felt her way forward until something pressed against her face near the neck — a hollow latex tube, thick as a cock, sealed at the top. No airflow. No breathing through it.

She didn't hesitate. She opened her mouth and swallowed it.

The tube sank to the back of her throat in one motion, cutting off any possibility of sound. Her eyes rolled briefly. She kept pulling the suit down until her head was fully enclosed.

The smooth black sphere in the mirror was identical to the one sitting in the tub.

She worked her hands into the sleeves, pulled the torso section up over her breasts — the integrated nipple pads delivered a continuous low current of sensation the moment the latex closed over them. She drew her legs up, fed her feet through the crotch opening, and straightened until the suit covered everything down to her toes.

At the rear: an uninflated latex bulb. She pressed it into place. It self-inflated and locked to the inner walls.

The crotch entrance drew closed to its resting tightness. Ms. Su retrieved the final piece — a specialized hollow tube — and pressed it into the vaginal opening.

Click.

The interior lock engaged. The tube was hollow, its inner walls patterned after natural vaginal folds, but the external surface had no release mechanism. Nothing to grip, nothing to pull. Sealed from the outside with no way out.

The suit surface began to contract.

Ms. Su's 170-centimeter body compressed, reshaped, and settled into exactly the same proportions as the doll in the tub.

She stood before the mirror and looked at the smooth, faceless, featureless black form. Inside the suit, her body was held in total compression. The tube lodged in her throat kept stimulating the gag reflex and something adjacent to it in continuous slow pulses.

She couldn't help touching herself — running latex hands over the sealed latex body. Then she picked up one of the standard-size vibrators from the shelf and, thinking about the moment she'd pulled those enormous plugs free and the doll's response, she pressed the tip toward the small opening at her mouth.

A hand came from behind her and wrapped around her waist.

Who —?!

Before she could react, the second hand closed over hers on the vibrator and drove it through the mouth opening in a single merciless thrust.

Slick —

The vibrator bottomed out against the tube already seated in her throat.

The next two were already in motion — pressed simultaneously against her lower openings and shoved home.

Slick — slick —

All three seated at once. Ms. Su's body went rigid. Her hands moved instinctively toward her crotch, trying to pull them free.

Behind her, the doll who had been lying in the tub moved. One of its hands came up to the back of Ms. Su's head. A fingertip found the barcode. Because both suits were from the same paired set, the student could activate Ms. Su's inserts directly through her own.

Beep. Beep. Beep.

Three tones, simultaneous.

The vibrators inside Ms. Su's body began to expand, vibrate, and rotate at the same moment.

Mmmmh — !!

Ms. Su's doll-body convulsed immediately. Her legs shook. One hand pressed against the latex of her lower abdomen — the two lower units had reached that depth. The other hand moved to her throat — the upper unit was already that far in. She could feel all three of them precisely: the one in her mouth pressing to the base of the tube lodged in her throat and continuing to swell; the lower two advancing to the ends of their respective sealed cavities, pushing the latex walls to their structural limit.

From outside, the doll's surface showed nothing. Not a single visible deformation. Only the person inside could feel what was filling her — and how completely.

The student doll embraced her from behind. One hand worked the latex breasts. The other drew slow circles over the taut crotch panel.

So this is what it felt like for her. This is what she was carrying. This big. This full. Still moving inside…

Ms. Su's awareness came apart in waves. The three units ran at maximum expansion inside her. High after high moved through the sealed body with nowhere to go.

Eventually, the student doll found the barcode again and deactivated the expansion. The three vibrators were drawn out in sequence. Ms. Su's doll-body slid to the floor and lay there twitching.

Two identical black latex dolls cleaned each other in the bathroom — soft cloth moving carefully over every centimetre of smooth surface — then opened the door.

The sound woke Lin Yuan.

He'd drifted off on the bed. He rubbed his eyes.

Two identical black latex dolls stood in the bathroom doorway.

“… Two of you?”

He sat up. His cock was hard before he'd fully processed what he was seeing. He had no way whatsoever of telling them apart — teacher and student, indistinguishable.

Both dolls climbed onto the bed. One to each side. They lay down against him.

Each extended one smooth black latex hand and closed it around his cock, beginning to stroke in matched rhythm.

The other two hands found his nipples — pressing, rolling, working through the latex with light persistent pressure.

There's no way to tell. There's just no way.

He looked left. He looked right. Two identical featureless black forms. Their movements were synchronized and unhurried, the warmth of their hands transmitting through the thin layer of rubber. Between that and the continuous stimulation at his chest, his cock went rigid as iron.

In the dark, only the faint gleam of two smooth black surfaces catching the light from outside the window — and Lin Yuan's breathing, growing heavier.
