Erika Nelson had known Mila Brooks since they were six years old and she'd been quietly, hopelessly obsessed with her for at least the last five of those years. They were opposites in every way that mattered. Erika was the loud one, wild dark red hair chopped at her jaw, sharp green eyes, a compact gymnast's body with small tits and a tight little ass, always ready to die on whatever hill her opinions built that day. Mila was the quiet one. Shy, calm, sweet, but somehow with Erika she always had fun, and could even stand up for herself a little. The problem, the eternal cruel problem, was that Mila was not into girls... at all. Whenever Erika got too flirty, Mila would get weird and brush her off with, "We're not kids anymore, stop making those jokes." So Erika kept her mouth shut and her hands mostly to herself. Then last week, Mila had asked for help getting a guy. Erika HATED it! But she couldn't say no to that face and she knew if she just tagged along she'd loom behind Mila glaring, scaring off every inferior option like a guard dog. There had to be another way and Erika, being a woman of many weird fetishes, had exactly one kink she'd never gotten to try.
Honestly, it baffled her that Mila was single anyway. Sure, her long blue hair was a clumsy shoulder length mess she never styled and she never touched makeup. But her body. Gods, her body. Soft round face, big anxious blue eyes, wide hips, thick thighs, a plush ass and breasts like melons. Like goddam MELONS! Heavy, full, jiggling with every step. Erika knew exactly how beautiful that body was because she'd "playfully" touched it in all the important places over the years. So she'd made her pitch. "Bestie, there's an app. A real one. It can turn me into a thing. I could become," and here she'd actually drooled a little, "your swimsuit. You'd wear me and I wouldn't get in the way at all." Mila had looked at her like she'd grown a second head. But she thought about it, because she was naive and pure, too pure for this world and finally said, "I guess we could do that. But how would I talk to you? If something happens, I should turn you back immediately, you know…" "There's a voice option," Erika giggled. "And a chat option. My messages show up on your phone." Mila had blushed, rubbed the top of her own head and said, "Well… I suppose you're really not against it. Send me the app. Pool at twelve, the usual spot." Erika had practically levitated home to get her stuff and go to the public pool.
Now they stood in the changing room, tiles cool underfoot, the air thick with chlorine and old shampoo and warm wet concrete. Most of the morning crowd was gone. Perfect timing, right before the afternoon swarm of women rolled in. Somewhere across the room, two strangers chatted while packing up. "...told him if he doesn't text back by Sunday I'm done." "Girl, you said that last month." "Okay, did you install it?" Erika whispered, bouncing on her toes. "Yes, yes, I did. It's fascinating! It knows everything about me. It's kind of embarrassing, actually..." Mila held up her phone, screen glowing with a dark interface. Name: Mila Brooks. Age: twenty-two. Three tabs at the bottom: Editor, Tags and Bio. "We don't have much time, add me!" Mila tapped and a popup bloomed. Do you allow user Mila Brooks to edit your information? Erika stabbed YES on her own phone so fast she nearly cracked the screen. Profile: Erika Nelson, selected. "Mila... Mila. Can I choose my form?" Mila's cheeks went pink. "Ehm... Sure? I mean, you're the one transforming, not me."
Erika giggled and typed with shaking thumbs. One-piece swimsuit, nylon and spandex blend, color: deep blue and then, biting her lip, she set the size a few sizes too small. She wanted to be STRETCHED over that body. She wanted every curve to fight her seams. She shoved the phone into Mila's hands. "You click it, or you won't remember I was ever a woman!" "Oh! Ah, okay!" Mila tapped UPDATE. The parameters set in. It started as a coolness washing over Erika's skin, like stepping out of a hot shower into air conditioning. She looked down and watched her skin turn blue. Deep glossy blue, spreading up her arms, down her belly, her freckles vanishing under it. 'Oh... Oh wow! Okay... it's actually happening~' Then her details started to flatten. Her belly button smoothed into her torso. Her collarbones sank. Her nipples pressed inward and vanished, and for one dizzy second she looked like a sketch of a girl, an outline printed onto her own shape. Her lungs went next. She tried to inhale and there was nothing to inhale WITH, no chest, no throat, just smooth stretchy material where her insides used to be. No air or voice she truly was inanimate now. Mila's face crumpled with worry, hands hovering. 'Oh no, oh no, is she suffocating?! Should I undo it? What do I do?' Erika winked at her. Last thing her eyes ever did. Mila's shoulders dropped an inch knowing she was fine.
Then the real changes came. Her limbs pulled inward, arms folding down into her sides like wet ribbon being reeled in, fingers already gone, legs shortening, knees dissolving, her whole lower half compressing upward. Her head sank down into her shoulders, face smoothing away, hair melting into the blue. Every retraction felt like a full body shiver, sensation folding in on itself, getting denser, richer. 'This feels... oh gods, this feels GOOD, why does this feel so good~' And then she hollowed out. Her core simply emptied, back splitting open into leg holes and a scooped neckline, her insides turning soft white lining and one last moan escaped from somewhere that no longer had a mouth. "Ahhhhhhn~" **FWUMP** She dropped onto the bench, a small crumpled pile of shiny blue fabric. Her surface tightened, went glossy, and shrank. And shrank. Sensation was EVERYWHERE now, no center to it. The wooden bench grain pressed into her back panel like fingertips. The chlorine air moved through her leg holes like breath.
Mila picked her up and held her out with both hands, stretching her slightly, and that little stretch alone made Erika's whole form quiver. 'Hnnngh~ do that again, do that AGAIN!' Mila turned her over, frowning at the size tag, then at her own melon chest. "Erika... there's no way. Should I make you bigger?" Her phone buzzed on the bench. Erika: no!!! it's perfect!!! Mila sighed the sigh of a woman who had worried about this exact friend for sixteen years, hooked her thumbs into the leg holes and started to pull the swimsuit open.
Mila stripped down first, folding her clothes into a neat locker stack because of course she did, and Erika got a full private show of that body. Heavy breasts swaying free, soft belly, wide hips, and then Mila picked her up and pushed one foot through her leg hole. 'Oh~ OH~' The foot slid through her, warm skin dragging along her inner lining, and Erika felt every toe, every inch of ankle, like a slow lick through her whole being. The second foot followed. Then Mila started pulling her UP, and the stretch began. Calves, knees then those thick thighs and Erika's leg holes had to widen, her fabric pulling taut, threads straining in the most delicious way, like every muscle she used to own being stretched at once in a full body yawn that never ended. **SHHHKK SHHHKK** Then Mila tugged her crotch panel into place and Erika's mind whited out. Warm soft labia pressed flush against her fabric. She could feel the exact shape of them, the plush outer lips flattening against her, the tiny seam of heat between them, the little firm bump of Mila's clit nestling right into her material. Since she was sizes too small, she didn't just cover that pussy, she was pulled INTO it, snug up against every fold. 'That's her pussy~ That's her actual pussy pressed on me, I'm touching it EVERYWHERE at once, oh my gods~' Mila kept pulling. The suit stretched up over her soft belly, and Erika felt the warmth of her navel dimpling into her front panel. Then the cups, and Mila had to actually wrestle her over those melons, gathering each heavy breast and stuffing it into fabric that had never planned for this. Erika's cups stretched to screaming, nipples pressing into her lining like two warm pebbles, breast flesh bulging at her neckline. Straps snapped over shoulders. **SNAP**
"Nnn!" Mila winced. Erika would have moaned if she had a throat. Every point of contact sang. Shoulders, back, ass, that plush ass filling her rear panel and swallowing her edges and the pussy, always the pussy, radiating heat through her crotch like a hand cupped there permanently. Mila's phone buzzed weird at first, garbled fragments, because Erika's mind was pure static. Erika: hhnfgkk Erika: so warm Erika: iggnore that She learned fast, though. She could hold the thought steady, THEN send. Like breathing, if she still breathed. Mila: Are you okay?? Am I not stretching you too much? Erika: it feels very good, promise Mila: ...good how? Erika: good to be with you <3 Mila stared at her phone, cheeks pink, then gave the mirror a thumbs up and walked out to the pool deck. Every step was an event. Thighs shifting inside her, ass cheeks rising and falling against her back panel, breasts bouncing in her overworked cups. The sun hit them and Erika's fabric drank the warmth. The air smelled like chlorine and sunscreen and hot concrete and underneath it all, faintly, the clean skin smell of Mila soaking into her threads.
Mila waded in at the shallow end and cool water flooded through Erika's fabric. 'AH! Cold cold cold, oh, oh that's nice actually~' The water made her cling tighter, suctioning her against every curve, her crotch panel plastered flush to those warm lips while cold water swirled around the edges. Hot pussy on one side, cool water on the other. Erika's whole existence became a temperature sandwich and she loved it. Then Mila got out, dripping and started the real mission. Erika could feel her heartbeat picking up through her chest panel, the nervous sweat starting under her arms. She was anxious. So Erika did the only motivating thing she could do. She flexed. Tiny contractions of her fabric, a gentle squeeze against Mila's pussy and nipples, little pulses of pressure. Mila jolted, went red, and marched toward a group of guys by the deep end like the squeeze had been a starting pistol. The talks were awkward, but they happened. One guy chatted about the weather. Another asked for her number and Mila glanced at her phone in terror. 'If Erika texts something insane while he's looking at my screen I will simply die! I will burst into flames right here on the pavement.' So she said no and he went away.
Erika was thrilled. She wanted Mila for herself anyway, and she celebrated by wiggling her crotch panel against Mila's pussy in happy little waves. Mila: STOP THAT Erika: stop what 😇 Mila: you know exactly what, I'm in PUBLIC, you're being a menace, I swear if you She was typing with her head down, blushing, walking, not looking, and she never saw the guy coming the other way. **THUD** She bounced off a wall of chest muscle, the phone clattered to the pavement, and Mila went over the pool edge with a shriek and a huge splash. **SPLOOSH** Cold water everywhere, bubbles roaring past Erika's fabric, and then panic vibrating through the body inside her, because Mila was not a good swimmer, arms flailing, that big chest heaving. The guy didn't hesitate. He hit the water a second later and had an arm around her waist before she'd swallowed her second mouthful, hauling her to the ladder and up onto the deck. 'Whoa,' Erika thought, feeling that forearm press across her waist panel. 'Okay... Strong...' He was athletic in the real way, not gym mirror way. Maybe six foot one, swimmer's build, wide shoulders tapering to a narrow waist, black hair buzzed short on the sides and wet on top, warm brown skin, dark eyes, and a crooked, genuinely cute smile that he was aiming right at Mila. A small scar cut through one eyebrow. His hand was still resting at her waist, steadying her.
'Please don't be mad I knocked you in,' he was thinking, ears going hot. 'Also please, God, don't let her notice I can't stop looking at her.' Erika was in crisis. The dunk had soaked her completely, making her cling to Mila tighter than ever, molded to every curve like paint. The cold water and the adrenaline had Mila's nipples hardening against her cups, two stiff points pushing into her fabric and the guy's hand warmth bled through her waist panel, and it was all so much at once that it was the single best feeling of her entire existence, human years included. She couldn't even focus on their words. Fragments got through. His name, Mike. Mila admitting, "I don't really visit public places much and I'm... not the best swimmer, obviously..." His laugh, low and easy. "I could teach you, if you want. I'm here most weekends." 'Wait,' some distant part of Erika's melting mind managed. 'Wait! Are they... is this...' Then Mila shifted her weight, thighs sliding, wet fabric dragging across her pussy and Erika's thoughts dissolved back into the stretch and the slick and the clinging cold. Mila smiled up at Mike and didn't say no, but Erika was too into her own world to understand what was happening up there.
They talked for over an hour and it was the easiest Mila had ever talked to anyone who wasn't Erika. Regular stuff. His job at the sporting goods store. The office job she hated. The weird hot dog stand outside the pool that had been "under renovation" for three years. Mike laughed at her jokes, the real kind of laugh and Mila slowly unclenched, shoulder by shoulder, sitting beside him on a lounger while the afternoon crowd splashed and shrieked around them. "Marco!" "POLO!" "Marco!" "He's literally right next to you, dude." Erika, wrapped snug around every inch of her best friend, noticed something before Mila did. Warmth blooming against her crotch panel. Then a slickness that wasn't pool water, thicker, warmer, seeping into her fibers from between those soft lips pressed against her. 'Wait... Is she… Oh my god, she's getting WET?! Her juices are soaking into me~' Pool water tasted like chemicals and nothing. This was different. This carried Mila's heat, her scent, salty and sweet, wicking through Erika's threads like she was a sponge built for exactly this purpose. Every time Mila laughed at something Mike said, another little pulse of warmth pressed through and Erika drank it straight from the source, dizzy on it.
Mike's eyes flicked down, polite but human, over the cups straining at their absolute limit, breast flesh bulging around the edges, seams pulled shiny. "That suit looks, uh… a little tight?" he offered, rubbing the back of his neck. "Not that it looks bad! It looks. Um…" Mila went red. "Oh! Yeah, it's, um, old… Wait here, let me grab my regular one, I have a spare! Stay right there!" He smiled. "Not going anywhere." Mila speed walked to the changing rooms, and the whole way Erika got the full ride, thighs pumping, breasts bouncing hard in her cups, hardened nipples dragging back and forth across her lining, wet fabric shifting against a pussy that was definitely, undeniably aroused now. Behind the lockers wall, Mila fumbled out her phone. The screen was a mess. Erika: hnnghhhf Erika: she likes him she LIKES him and i can FEEL it Erika: milaaaa you're soaking into meeee "Oh my god..." Mila covered her face with one hand, typing with the other. Mila: I'm so sorry!!! Also, I have to adjust you, sorry, no time to explain! She opened the Editor tab. Under Properties, she typed over Erika's careful specifications: regular swimsuit, correct size. Tapped confirm.
Erika felt herself CHANGE, fabric loosening a few merciful sizes, the white racing stripes along her top melting away into plain blue, her whole cut shifting subtly more modest. The stretch tension she'd been drunk on eased into a comfortable, full body hug instead. 'Hey! I liked being too small! Put it back, put it b... oh… oh, actually this is nice too, everything is still touching everything~' What neither of them noticed in the rush: the app auto-adjusted her base information to match the new properties. The profile header quietly rewrote itself. Where it had said Erika Nelson, it now read: Swimsuit #12. Mila caught it out of the corner of her eye as she closed the app. "Ha? Wait, that's weird, your profile..." But Mike was waiting. "Sorry bestie, I'll fix it later!" She jogged back out. Mike blinked at her. "That was like two minutes." "I'm a fast changer!" she giggled and where had THAT giggle come from? He looked her up and down, the properly fitted blue suit hugging her curves right instead of strangling them, and said, simply, "You look even better now." Mila's brain shorted out. She glanced at her phone like a lifeline. Erika: girl. GIRL! you can do it! Go get him tiger And Mila smiled, tucked the phone away and got him. They talked like the sun wasn't moving. Erika stopped following the conversation entirely, because being a swimsuit was just too good to be true. The warm skin, the slow soak of arousal into her crotch panel, the smell of chlorine and sunscreen and Mila all mixed into her fibers, the little shivers whenever Mike's arm brushed Mila's shoulder and her whole body responded. 'How am I ever supposed to go back? How does anyone go back from THIS?'
She surfaced from her fabric daze to a changed scene. They were in a dim room. Kickboards stacked on shelves, lane ropes coiled like sleeping snakes, the smell of rubber and chlorine and dust. Mila's heart hammering against her chest panel like a trapped bird and Mike, three feet away, hooking his thumbs into his briefs and pushing them down. His cock sprang free, fully hard, thick and flushed dark, a vein running up the underside, tip already glossy. He was breathing hard, pupils blown wide. 'She said she wanted to see it,' he thought, half disbelieving his own luck. 'Please don't let me embarrass myself in the first thirty seconds…' Mila stared at it the way a hiker stares at an anaconda that might bite her. Frozen, her eyes wide open. Hands pressed flat against the shelf behind her. Erika, plastered across every nerve rich inch of her best friend, saw that cock twitch and went into full alarm mode. Erika: MILA Erika: he's about to Erika: girl he is ABOUT TO! But it was too late. Mike gripped himself, stroked twice, groaned through his teeth, and erupted. **SPLRT SPLRT SPLRT** Hot cum roped across Mila's chest, her belly, her cups and Erika caught most of it.
'OH! OH MY GODS!' The heat of it hit first, so much hotter than skin, splattering across her fabric in thick heavy stripes. Then the texture, slick and dense and then the fizzing. A faint electric tingle everywhere it landed, thousands of tiny living sparks, the swimmers themselves prickling against her fibers as her material drank it in like rain into dry earth. Erika absorbed it, actually ABSORBED it and every drop that soaked deeper sent pleasure rippling out across her whole form. It felt divine. There was no other word. Mila made a sound that wasn't a word either. High, strangled, somewhere between a squeak and a whimper. "Hnnn~" But her body told the truth against Erika's lining. Her heartbeat went wild. Sweat bloomed under her arms and along her back and her pussy, pressed flush against Erika's soaked crotch panel, twitched. Then clenched. Then flooded a fresh wave of slick heat into the fabric. She was into it. Terrified, scandalized and absolutely into it. Mike's face fell in horror at himself. "Oh god, oh god, I am SO sorry, I didn't mean to, that's never..." Mila looked at him. Looked at the cum cooling on her chest. Looked back at him with an expression neither of them could have named. Then pure body instinct took over and she grabbed his face and kissed him hard on the mouth.
The kiss broke something loose in both of them. Mike's hands went everywhere, and everywhere meant all over Erika. Palms sliding down Mila's sides, gripping her waist through wet blue fabric and every point of pressure lit Erika up like fingers dragging across bare skin. He pulled Mila against him and his cock, still hard, already leaking fresh precum, rubbed up against Erika's front panel, smearing hot slick across her belly section. 'He's grinding on ME, his cock is rubbing on ME, oh fuck~' He cupped her breasts through the suit, massaging them gentle at first, then playfully harder, squeezing the heavy flesh so Erika's cups compressed and released, compressed and released, Mila's stiff nipples dragging across her lining with every knead. Mila made a helpless sound into his mouth. "Mmmmph~ hnnn~" 'She's real,' Mike thought, thumbs circling those hard peaks through the fabric. 'This gorgeous shy girl is real and she's shaking and I want to hear every sound she's got.' He got her against the shelf, slid a hand down and pressed two fingers against her pussy through the crotch panel. Through ERIKA. His fingertips rubbed slow circles right over Mila's clit with Erika's soaked fabric as the only barrier, and Erika felt both sides at once, the firm press of his fingers, the twitching heat of Mila's swollen clit, her own drenched material trapped between them, dragged in circles. **SHLICK SHLICK SHLICK** Mila's thighs started trembling. Her breath went short and high. "Ah~ ah~ wait, I'm, something's, AHHHN~!" She squirted all over the place.
Hot fluid gushed through Erika's crotch panel, soaking it completely, spraying past the fabric edges, spattering the concrete floor between Mila's shaking feet. The bottom half of the suit was drenched in an instant, and Erika drowned in it, drinking Mila's release straight into her fibers, every thread pulsing. 'She came, she came THROUGH me, I felt the whole thing, I felt everything~!' **SPLAT SPLAT... DRIP... DRIP** Mike didn't give her time to be embarrassed. He tugged Erika's cups down and Mila's breasts spilled free, bouncing, nipples hard and flushed. He pushed the soaked crotch panel aside with two fingers, and Erika got pulled taut against Mila's inner thigh, stretched at the corner, and then he lined up and pushed into her raw. **SCHLORP** Mila's whole body arched. Erika, wedged against the crease of her thigh, felt everything from the outside in. The stretch of Mila's lips around his shaft, the wet heat, the way each thrust dragged his cock along the corner of her crotch fabric so she got fucked against too, friction rippling up her whole form with every stroke. **PLAP PLAP PLAP PLAP** "Ahn~! Ahn~! Mike~! Ahhhhn~!"
He fucked her against the shelf until the kickboards rattled, hands gripping her ass through Erika's back panel, and when he finally came he buried deep with a groan, and even with his stamina he had to sag against her after, chest heaving, sweat dripping onto Erika's straps. Mila panted, legs jelly and fumbled for her phone with shaking fingers. Mila: aer you okay??? are yuo fine???? Erika: yes~ yes yes YES Erika: question. can you change my bio? Mila: why? Won't everyone forget you if I do it? Erika: Miss Nelson. Everything clicked in Mila's head at once. Erika's mother. That woman was crazy protective, the kind who called the police if Erika was forty minutes late. If she found out Mila had anything to do with her daughter vanishing, Mila would be turned into a kitchen sponge for a month and she could NOT allow that. Not now. Not when she'd just met this awesome guy. Mike lifted his head, grinning lazy. "You ready for round two, or do you need a minute?"
"One minute!" Mila squeaked, typing like her life depended on it, because it sort of did. She generated a biography as fast as her thumbs could move. Blue one-piece swimsuit. Manufactured in the USA. Purchased online for $30.99. Machine washable, cold cycle. Saved. Closed the app. Shoved the phone back in her bag and in that quiet moment, Erika did one last thing herself. She reached through her connection to the app and hit DISCONNECT on her own end. This was too good to be true, and she wasn't letting anyone undo it early. When she'd had her fill, if she ever had her fill, she'd ask to reconnect. For sure. Round two happened on the floor mat. Erika stayed pushed aside and pulled down, half worn, half ravished, and her mind sank so deep into the bliss she stopped forming words at all. He came on her again at the end, ropes of it across her cups and belly panel, and as it cooled the soaked parts went slowly crusty, stiffening, and even THAT felt incredible, her senses sharpening as everything dried, the scents getting louder, chlorine and sweat and cum and Mila's pussy all baked into her threads. She drifted off into a limbo of pure fabric ecstasy, then a blackout.
Erika swam back to awareness in warm running water, Mila's hands kneading her under the faucet, the smell of gentle soap replacing everything else. "Erika, I can't turn you back while you're covered in Mike's spunk, that would be so weird," Mila muttered, scrubbing. "Okay... I think that's everything." It was not everything. Erika could still feel cum and pussy juice ghosting deep in her fibers, and she hugged that knowledge to herself smugly. Mila dried her hands and opened the app. "Okay, let's get you... huh?" She scrolled. Scrolled again. "Wait. Where's your profile?" Swimsuit #12 sat there with its generated bio. No Erika Nelson anywhere. Heart dropping, Mila dug into the logs, and found it. User Erika Nelson: DISCONNECTED (self initiated) and right above it, one last message, timestamped from the storage room: Erika: i want to stay a swimsuit longer. gotta support my besty<3 don't you dare turn me back before you're confident
Mila stared at the screen. Then at the damp blue suit draped over her towel rack. Her face went red and her eyes went wet at the same time, and she picked Erika up and hugged her against her chest. "Thank you. Really… and, um, actually it's perfect, because I wanted to ask you anyway." She fidgeted with a strap. "Mike's giving me swimming lessons. Every weekend and he, um. He really liked you too. The suit. You… You know what I mean!" Erika couldn't answer without the app. But she remembered his cum soaking hot into her fibers, and if fabric could purr, the whole bathroom would have heard it. Mila hung her carefully on the drying rack, still blushing, already thinking about next Saturday. With both of them coming to terms with it, the only real question left was how long this arrangement would go on. Neither of them was in any hurry to find out.
