Kristen was twenty-one, about to finish her last year of college and still basically on her parents payroll. She lived alone in a small apartment a few blocks from the family house, worked the desk at her mom's gym, and told herself the money was a salary and not an allowance. Her red hair hung to her shoulders because styling it felt like a waste of time, and her body did the styling for her anyway, a soft curvy 5'6 with heavy C cup tits and hips that made her jeans fight for their lives. Her little sister Karen was eighteen now, just starting her first semester and getting more insufferable with each following year. Kristen stood in her bedroom holding her only clean pair of leggings up to the light. A huge brown stain ran down one thigh like someone had spilled coffee and guilt on it. 'Are you kidding me?' She pinched the bridge of her nose, grabbed her keys and drove to her parents place. She had an old pair in her room there somewhere. The house smelled like it always did, warm bread and hot solder, because her dad Jack was what her mom called an electricity bill menace. Some months the power bill looked like a phone number. Some months a patent check made it all okay. She was halfway to the stairs when she heard him swearing in the basement. That specific tone. The something broke and I need a witness tone. She sighed and went down.


Jack was crouched behind a machine that looked like a washing machine had eaten a printer and regretted it. Panels from three different projects, cables zip tied into bundles, a big touchscreen on the front, and a wide container slot at the base. "Dad, is everything fine?" He looked back, wild eyed. "Fine!? It worked this morning and now look, it is bugged again. Hey Kristy, please give me the screwdriver." She handed it over. He vanished behind the machine again, working blind, not even looking at her. "So what is this thing even, Dad? I guess this is the reason you didn't answer my calls or messages." He sighed. "Yes, it is. It's my take on 3d printing! It's just genius. I made a flexible material that can be shaped into pretty much any form. Think how amazing that is!" It did sound interesting. He stood, ran diagnostics, and his whole face lit up when the bars went green. Then it fell. "Okay, looks good. Where's your mom, I promised to help her at the gym." "Dad. It's already late. Mom is there already working." 'I am a dead man,' Jack thought, grabbing his jacket. "Don't touch anything," he said, the four words his daughters had never once respected. "Take my car," Kristen offered. "Thank you, sweetie. Don't take too long, it's newbie month at the gym, so we have a lot to do." And he was gone up the stairs. Kristen looked at the machine. The interface glowed, friendly and clean. Custom shapes, sliders for durability and elasticity. A little gauge read Blueium tank one-fourth full. 'I could go dig for old leggings. Or ask Karen. Ugh! Or...'


She went to the console and typed in leggings. A blue 3d model spun on the screen, hugging an invisible body. She set elasticity high, hit start, and blue mass flowed up from the base of the machine, thick and shiny like melted glass. Rods spun around it, pulling it into a waistband shape and then... **BZZT BZZT** ERROR. NOT ENOUGH BLUEIUM FOR DESIRED SHAPE. INSERT MATERIAL INTO CONTAINER BELOW. The half-formed blue mass got sucked back down into the container. Kristen hunted around the lab, found a spare brick of the blue stuff on a shelf, came back and leaned into the container slot to set it in place. The machine started on its own. "Whaaaa..." The rods spun. The Blueium rose, and it did not go into the mold. It went into her. It climbed her arm like warm oil sinking through her skin and her hand turned a glossy blue right in front of her eyes. "No no no NO!" MATERIAL BONDING. ERROR. ERROR. UNKNOWN BIOMASS DETECTED. ADJUSTING. The warmth spread. She felt it pour up her arm into her chest, and her whole body started to tingle like a limb waking up, everywhere at once. Her skin went blue in spreading patches, shiny and slick. It hit her tits and she gasped because they suddenly felt heavy and soft and hot, her nipples going stiff and sensitive against her bra like every nerve in them had doubled. "Ahhhhh~ w-what... unnnngh~" It sank between her legs next, warm and thick, soaking into her pussy like a slow tongue, and her knees buckled against the machine. "Mmmmmh~ n-no... stop, that's... hnnnngh~" Her hair went blue at the roots and washed down to the tips. "My hair, no, what happened to my HAIR?!" she screamed, watching red drain into deep glossy blue in the machine's reflective panel. The tank gauge dropped to empty. It was all in her now. REMOVING UNKNOWN OBJECTS.


Grabber arms snatched her clothes and pulled. Her tank top stretched off her and took her upper body with it for a second, her torso pulling like taffy before snapping back, tits wobbling like water balloons. Her jeans peeled down and her legs stretched three feet long and slurped back to shape. She stared at herself, naked, blue, gleaming. 'I'm... soft. Oh god, I'm SOFT!' BEGINNING SHAPING SEQUENCE. The rods closed in. A press came down on her shoulders and she just... folded. No pain. Her bones felt like warm wax giving up. Her arms got rolled into her sides, kneaded flat, her hands smearing into her hips like dough. "Ohhhh~ ahhhhh~ it doesn't hurt, why doesn't it hurt?!" **SQUISH SHLORP** Her legs stayed. The machine wanted legs. It hollowed her out instead, rollers thinning her thighs into sleeves, her calves into tight tubes, and every pass of the rollers dragged across her oversensitive pussy as her hips got molded into a snug waistband and she moaned, loud and shaking. "UNNNNGH~ ahhh~ AHHHH!" Her tits got pressed flat into the fabric of her own thighs, nipples stretched forward and smoothed away and the sensation of it made her whole flattening body shudder. Her head was last, her face going soft, sinking down into the waistband, her scream thinning into a squeak as her skull spread flat. SHAPE COMPLETE. SETTING FORM. **BZZZZZT** One sharp shock. Everything locked. On the output tray sat a pair of shiny blue leggings with two white stripes, and Kristen could not move or make one single sound.


Footsteps. "Sis, are you in Dad's lab..." Karen came down, saw nobody, saw the errors. "Such a dumbass," she muttered, typing the security camera password like it was nothing. She watched the footage. Her eyebrows went up. Then the smirk came, slow and evil, and inside the leggings Kristen felt goosebumps she didn't have anymore. 'Oh, this is the best day of my entire life,' Karen thought. "What did my dumb sister get into?" She picked Kristen up, stretched the waistband wide. **STRRRETCH** "Cat got your tongue?" She giggled. "Well… Well, it would be a shame not to try you out." Karen stripped her own leggings off and slid Kristen up her bare legs and Kristen felt everything, the warmth of her sister's skin, the sweat, the smell of her pussy pressing right into her and over it all that vanilla shampoo scent Karen always used, sinking into her like she was a sponge. Karen pulled the waistband out and let go. **SNAP**


Karen jogged the whole way to the gym, and Kristen felt every single step. It was awful. It was so much. Her sister's body heat soaked through her from the inside, thighs pumping, sweat beading up on warm skin and sinking straight into Kristen like she was made to drink it. She was. Salt and skin and that vanilla shampoo smell that clung to everything Karen owned. On the outside, the evening breeze slid cold across her shiny surface while Karen's ass bounced against her from within, warm and round and rude and the two temperatures met right in the middle of what used to be Kristen's body. 'Oh, my god. I can taste her SWEAT EWWW. I can taste my sister's sweat.' Karen glanced down at her own legs mid-stride and grinned. "Comfy down there, sis? You're really breathable, I gotta say. Five stars!" She hopped a curb just to make herself bounce harder. **SLAP SLAP SLAP** went her thighs together. "Oops… Sorry. Was that your face?" At a crosswalk, she did deep standing stretches she absolutely did not need, folding forward until Kristen strained tight over her ass, fabric creaking. 'Mmmmph~' Kristen wanted to scream, but nothing came out. The shock had locked her voice completely. "Cat still got your tongue?" Karen patted her own hip twice, like petting a dog, and jogged on. The gym was slammed. Newbie month. The front desk had a line, treadmills all taken, the whole place smelled like rubber flooring, cleaning spray and thirty strangers fresh sweat. Jennifer, their mother stood behind the counter running memberships, tall and blonde and built like the reason half the men signed up, and Jack was beside her fumbling with the card reader.


"Karen, finally. Where's your damn sister? She's on desk tonight." Karen smiled sweetly. "Kristen couldn't make it today. She had a more important job to do. But don't worry, she's real close by." Jennifer sighed and looked out at the crowd of newbies. 'Half of these people won't last to week four and now I'm short a daughter too...' Karen hit the floor. She did squats directly in front of the mirror wall and Kristen was stretched skin tight over her sister's ass in front of God and everybody. A group of big trained guys by the racks started looking. Of course Karen noticed. She turned, bent slow, touched her toes, held it. 'Karen! KAREN! They are staring at me. They are staring at ME.' "These leggings?" Karen said to one of them, running a palm down her own thigh, down Kristen's face. One of the guys smirked. "Karen, those look great on you. Where did you get them?" "Thanks. They're one of a kind. Super personal to me." She winked. Kristen wanted to die.


The gym ran late. The plan was for Kristen to take the night shift, so their mother stayed behind to wait for her while Jack drove Karen home in Kristen's car. "It's weird," he said at a red light, drumming the wheel. "She gave me her car. Where would she even go?" In the basement, he stopped cold. The output log was full. The Blueium tank read empty. He turned slowly and looked at Karen. At Karen's shiny blue leggings with the two white stripes. "Did you use the machine? It's very dangerous, dear! I told you and your sister, never touch my stuff without me!" Karen smirked. "I know that. Kristen doesn't." "...Kristen doesn't?" She pointed at her own legs. "Yes. She's right here." Jack pulled up the security footage and watched his oldest daughter get kneaded into sportswear. His face went through five different colors. "Karen. Why did you not tell me sooner?!" "What? You always told us new devices need testing! So I tested the product..." She snapped the waistband. "It's very nice." 'I raised a small demon…', Jack thought, rubbing his eyes. He held out his hand and gave her The Look until she peeled Kristen off and Kristen nearly wept from relief as the warm sweaty prison of her sister's body finally let her go. He laid her on the machine bed and hit the reset. **BZZZZZT** The shock cracked through her and everything unlocked. The leggings twitched, then bulged, the machine's rods guiding as blue mass swelled up, legs splitting free, a torso rising, tits inflating soft and heavy, a head pushing up out of the waistband with a wet **SHLORP**


"Ahhhhh~ hahh~ hahh~" Kristen stood there gasping and completely naked. Jack spun around. "Clothes! Put some clothes on!" She grabbed a lab coat. And froze at her reflection in the machine's steel panel. Her skin had a faint blue tint, soft and slightly glossy. Her hair was fully, deeply blue, like that Miku character her friend Mia cosplayed, but darker. She touched her own arm and it dimpled like memory foam. 'I look like one of Mia's cosplays. I look like a cosplay of MYSELF!' Jack exhaled. "Well… good news, you're not putty on the floor or anything not human. You're almost fully you. Bad news, the Blueium is fully integrated. If I try to take it out now, it could damage your cells. So until I build something that works, you stay like this." "Dad... can't you do your science stuff and turn me back faster?" "I'll try, but I have such a big backlog and I mean, you are fine, just be careful an electric shock locks you in your form, but I guess you already got it..." He grabbed her wrist and squeezed. Her flesh squished flat between his fingers like clay, turning brighter blue, and stayed squished when he let go. "See! The more you get changed, the longer your body takes to snap back. Maybe skip strength training for a while. After your shift, come back, we run tests. Now go get ready or your mother will get angry, and when I tell her that you can be squished, I can only imagine..."


Kristen did not need to hear more. She ran upstairs to her old room, digging through drawers, muttering. "Stupid machine. If I'd just looked for my old leggings, I wouldn't be like this. And my red hair is gone, ughhh..." She found her old pair. She stripped down to nothing to change into gym underwear, and that was the exact moment the door slammed open. **WHAM** The door caught her full body and smashed her flat against the wall. She spread across it like a swatted bug, three feet wide and an inch thick, her tits squished out sideways, her whole flattened body glowing bright blue, and the sensation of it rolled through every squashed nerve at once. "UNNNNGH~ ohhhh~ ahhhhh~" Karen leaned in and pulled the door back. Her flat blue sister stayed stuck to the wall like a poster, face turned away, cheeks somehow still blushing. "Oh, look at you." Karen giggled. "I wonder how long THAT takes to fix. You know what, I'll do your late shift. But you owe me one!" The door clicked shut. Footsteps faded down the stairs. Slowly Kristen unstuck from the wall, peeling free inch by inch, and dropped, folding over herself into a loose blue heap on the carpet, half flat, half girl, unable to stand. "Anyone..." she called out into the empty house. "Can anyone help? Anyone…" No one did answer.
