“Ayase-san, could I speak with you a moment?”

Yue looked up from toweling the last bit of her hair to find Chachamaru standing over her. “Do robots even take baths?” She thought to herself.

“Then I’ll go on ahead!” Haruna called from the changing room door.

“Ok,” Yue answered her friend. “What is it Karakuri-san?” She regarded the robot girl. She couldn’t remember ever seeing Chachamaru using the dorm bathhouse before, and it still didn’t look like she had, even though she was clad only in a towel. Yue raised an eyebrow as the robot glanced around the empty changing area.

Satisfied that they were alone, Chachamaru looked down at Yue, took her by the shoulders, and kissed her deeply on the lips.

Yue’s eyes widened. She tried to escape, but the taller girl held the distance and she soon found herself trapped against the wall. She’d never expected this to happen with a girl, much less a robot. Her mouth felt warm, and it was quickly spreading down her throat. She was finally able to pull away, taking a deep breath. There was a funny taste in her mouth as the warmth hit her belly and spread outwards. She looked up at Chachamaru, still panting deeply as she began feeling increasingly hot. “W-what do you think you’re doing?” She managed.

“Please comply, or the process may be uncomfortable,” Was all the robot girl answered.

When Yue opened her mouth to retort, she was only met with Chachamaru’s lips once again. However this time, she could only melt into the artificial girl’s embrace. “What am I doing?” She thought desperately to herself. “We can’t do this here... Wait, we can’t do this at all!” Yue told herself. She barely managed to escape from the kiss, looking up at Chachamaru with a pensive blush. After looking her over, the android suddenly spun her around. Yue felt both their towels fall to the floor of the changing room. Clockwork arms wrapped around her, and she could feel their owner against her back. Chachamaru was much warmer than she expected. She gasped as hands suddenly covered her small breasts. Yue went almost limp as her nipples were slowly stroked. The heat inside her compounded all the sensations. She heard an audible click as she unexpectedly felt something push between her legs. Something long slid against her sex, causing her to shudder in Chachamaru’s embrace. She looked down as she was caressed to find a phallic shape sticking up. Quickly she realized that the clockwork girl was adjusting her, to be penetrated! Her sex was already unusually wet, lubricating the tool. She squirmed, but hardly managed a weak motion. With a shift of Chachamaru’s hips she felt her lips part, and suddenly her struggles only helped the intruder into her further. Almost right away she could feel the tip swelling up and pulsing inside her. After a small spasm of pleasure Yue sagged in defeat, thoroughly over-stimulated. The gentle pleasure of having her nipples rubbed still buzzed through her. Some small part of her mind still questioned what was happening, even though most of it was beyond caring.

Just when she thought it was over, Yue was confronted with a new sensation. Something pressed between her cheeks, presenting a gentle but constant pressure against her tight pucker. It continued its insistence, slowly spreading the tight hole. Yue blinked away a tear as it abruptly popped inside. Right away something began to pump into her. It caused the same warming sensation as the earlier kiss. She moaned out loud as the fire raced through her. Chachamaru held her tightly, quickly silencing her with a hand. All over she fell like she was swelling up. “No,” She realized, “Something isn’t right...” Opening her eyes, she was startled at the rapidly growing bulge in her midsection. Then she noticed, she wasn’t being filled, she was getting smaller! The extensions inside her distorted her form as she shrank. She wrapped her arms around her expanding belly, whimpering in pleasure. Somehow the more her skin stretched, the more sensitive it became. She hugged herself tightly as she grew impossibly distended.

Reduced in size to less than two feet, Yue could only hang helplessly from Chachamaru’s crotch. Still muffled by a now much larger hand, she moaned, unable to even move. She still managed to be curious about what would come next. The answer came soon enough, when a quiet hiss came from behind her.

Chachamaru’s belly snapped open, revealing a padded cavity. The projections between her legs rotated up, carrying the vulnerable Yue into her midsection.

A dazed Yue looked around at the soft material pressing in around her. She was powerless as Chachamaru carefully tucked her legs up against her chest. Her eyes widened one last time as the mechanical girl’s body closed her inside.

Chachamaru looked down at her now swollen body. Her rounded belly made her look almost pregnant. “I’m so big...” She commented to herself, showing just a little dismay. She began to get dressed, blushing at how differently her clothes fit now.

***

Evangeline McDowell drummed her fingers on the table impatiently. She stared at an empty teacup, resting her cheek in her other hand. There was a polite knock on the door to her cabin. She looked over as Chachamaru entered. “Well now, aren’t we looking maternal,” The vampire teased, appraising her servant.

The android blushed. She held her large belly sheepishly.

Evangeline gave her an odd look for a moment before shaking her head. “Any problems?” She asked.

“No Master,” Chachamaru answered. Receiving an approving nod. Then, after a moment of awkward silence, she offered, “Shall I remove her?”

Evangeline smiled, watching her doll closely just to see if she would squirm or fidget. “She’s been awfully self-conscious lately,” The girl thought to herself. The robot’s mistress waited, but despite any budding emotions Chachamaru might have, her automaton discipline was still resolute. Evangeline pouted a little, her fun ruined. “Alright, open up and lets see what I have to work with,” She finally commanded.

Still blushing, Chachamaru pulled back her clothes to expose her midsection. Her belly clicked open to reveal its occupant.

Yue squinted at the sudden light. As her vision cleared, she found Evangeline looking down at her, smiling wickedly. “Evangeline-san?”

With a smug smile, the vampire reached out and grasped Yue with both hands.

The touch acutely reminded the shrunken girl of just how thinly her sensitive skin was stretched. Yue’s eyes widened as she felt a pull. “Don’t! It’s too-“ She squeaked. With a triumphant grin, Eva tugged at the girl. The objects distorting her body tried to hold their captive, but slowly surrendered. Yue shuddered at their passage from her distended body, until finally, she came free with a wet pop. Her openings hung open in the cool air, gradually closing up, trying to restore some of their shape.

Evangeline looked down at the softly panting girl. “Aren’t you just adorable at this size? And much more manageable too,” She commented, rubbing at the girl’s tiny nipples. “I’d say everything worked just fine, wouldn’t you?” She looked at Chachamaru.

Now closed back up, the clockwork maid nodded, still blushing. “All additions worked as intended Master,” She affirmed.

Evangeline carried her diminutive classmate to the nearby table. She set her down on the edge, her legs hanging over.

Yue flinched as the cold wood met her puffy nether regions. She tried to ignore the cool sensation of the table against her still gaping holes. She steadied herself with her hands, her head still swimming.

“I think... lilac. What do you think?” She regarded Chachamaru as she presented her with a small leather trunk.

“It would match her hair nicely Master.”

“What do you think you’re doing?” Yue demanded weakly.

Evangeline held up a small, doll-sized petticoat against her, ignoring the tiny girl’s command. Laying the dress aside, she shoved Yue onto her back with one finger.

Yue practically collapsed under the force of the single digit. She couldn’t seem to catch her breath, and her body was still tingling from the large intrusions earlier. Her legs lifted, and she found Evangeline slipping a pair of frilly bloomers onto her. She was being dressed, like a doll! Yue squirmed as a slip was pulled over her head. Tiny bows were tied to secure the underwear, despite her writhing. Lifted by the legs, Evangeline slipped her upside-down into a light purple petticoat, just as frilled as the bloomers. “I-I’m not one of your dolls!” She insisted feebly as the petticoat was tugged into place. A hand around her midsection kept her under control as the vampire mage pulled the final, elaborate dress over her head. The fight was drained out of her by a gentle stroking on her chest, allowing the fitting to be fine-tuned by Eva’s expert hands. Through half lidded eyes Yue noticed something new, a wooden base on the table, with a piece sticking up in the middle. She wasn’t sure which disturbed her more, the part sticking up, with its large, two-pronged bulbous shape, or the fact that the metal plate on the front was engraved “Yue-chan”.

Evangeline lifted her up for inspection. “It is quite cute on you,” She said approvingly, slipping a finger between Yue’s legs.

The girl gasped as she discovered that for all the elaborate lace and frills, her crotch was still unprotected. “S-stop that!” Yue tried to insist, her cheeks darkening. She could feel the Dollmaster’s finger worming its way into her tender backside. Soon another, slipping into the receptive lips of her sex, joined it. Yue twisted, to her captor’s delight, as Eva spread and relaxed her fingers. Her body stretched each time in an unnatural fashion.

“The formula works like a charm,” Evangeline smiled broadly. She withdrew her fingers from her victim, giving them a long, slow lick. She placed Yue on the table, where she immediately collapsed.

Yue huffed, the constant sexual attention taking its toll on her stamina. Just when her sex had started to feel normal again, her still slightly distended cavities had been forced open once more. It’d jump-started the burning sensations in her body, causing them to return in nearly full force.

“No time to rest now, be a good little dolly,” Evangeline said with a smirk, holding up a hand.

Yue found herself unexpectedly on her feet at the mage’s gesture. Against her will, she took a halting step, then another. She fought with all her remaining might, but she continued to take stilted steps towards the engraved base. There were two feelings clashing inside her, a curious emptiness from her abused openings, and nervousness at the unusual stand with her name on it.  She marched towards it, her hands held out at her sides. With a twirl of Eva’s hand, Yue spun on her heel. With a worried look, she hiked up the back of her simple, but elegant dress. She tried as hard as she could, but she only managed a moment’s hesitation before gently seating herself onto the large, upside-down pear shape. She reached down, spreading herself, and began to work the large object inside. Yue let out a loud whimper as her bodyweight dragged her down little by little, until out of the blue, it popped into her. An extension, which could only be described as a dildo, speared between her lips as she settled into position. Even as she hung there, breathing heavily, she involuntarily straightened her outfit and took on a dignified pose. As her base was picked up and moved to a nearby shelf, Yue stood there with her hands demurely held in front of her. Under her dress, she could feel herself closing up tightly around the intruding bulb. Each passing moment, her body regained a little more of its natural firmness, securing her more permanently. She looked up numbly as she was patted on the head, causing her to bob a little on her pole.

“Look on the bright side, now you can watch me do all the magic you want, and maybe you’ll learn something, eventually,” Evangeline smiled darkly. “Goodnight dear,” She waved, totting off to bed with Chachamaru.

“It’s alright Yue,” A familiar voice said.

She was able to move her head just enough to see. Her eyes opened wide at the girl on the shelf next to her. She was sitting with her legs hanging over the side, in equally cute gothic clothes.

“Don’t worry, Evangeline-sama is very kind to her dolls,” Nodoka insisted.
