Lydia walked up the concrete steps to the train station, her wide hips swaying from side to side. She was still getting used to the odd shifting balance of her new pelvis. Vicky had fucked Lydia's pussy into unusability a handful of times already since they had first met, and Vicky's most recent selection for Lydia's replacement parts had given her wide, thick hips complete with a nice, round ass. Honestly, despite the awkwardness of how her hips swung when she walked, it felt nice to have a little counter-balancing. Her breasts had nearly reached the peak of their growth, swelling to nearly adult size (and even some adults might be jealous).

She felt a sneaky paw slip under her skirt and give her ass a nice pinch. Giving a little jump and a squeak of surprise she then swatted the paw away, growling "Vicky! Not out in public!"

Vicky smacked Lydia's paw away in turn and caressed Lydia's plump ass cheek, squeezing it with her fingers.

"You think I can resist grabbing your ass when it's swinging back and forth in front of my nose? You think I gave you a state-of-the-art, primo ass constructed with maximum squeezability in mind and not squeeze it any time I want? Girl you swat my paw away again and I swear I'll push you down on all fours and fuck you right here for the world to see," Vicky said, though her voice was more teasing than dangerous, and her grin, showing all of her teeth, looked playfully hungry.

Lydia huffed but didn't try to swat Vicky away again even when Vicky curled a finger to run right along the center seam of Lydia's panties, tracing her crack all the way up to her tail and nearly lifting her skirt up.

Not that anyone would have seen her panties. Under her skirt (and blouse) she had on a black, body-tight latex suit. At the moment she was wearing it almost like a one-piece swimsuit, but it could be extended to bind her arms, legs and tail and there was even a hood that could zip up to cover her head. After her rough introduction to S&M sex, Lydia's masochistic streak was growing deeper and deeper, and Vicky was only too happy to find new ways to tease orgasms out of her new fucktoy.

That was what Vicky had promised her for this trip, in fact. Vicky had somehow arranged things with the school and Lydia's parents to pull her out for a week-long vacation. According to Vicky, their destination was an isolated little cabin in the woods complete with a fully-furnished sex dungeon. There, Vicky would teach Lydia all sorts of new ways to enjoy pleasure and pain.

Just the thought of their magical little getaway was making Lydia's nipples hard and putting a tickle in her pussy. Vicky's constant pawing at her ass didn't help, especially when she kept it up at the ticket counter. The guy at the counter just gave them a bemused look and waved them through, though.

"The only thing anyone who sees us is thinking," Vicky purred into Lydia's ear, "is 'man I wish I was grabbing that bomb ass too."

Lydia gritted her teeth and bore it, fighting all her urges to smack Vicky's paw away again. Her cheeks were hot, but she couldn't tell if it was from shame as she felt eyes on her, on them, or from her arousal. In fact her horniness just added to the shame. She imagined what the people staring at them would think if they knew all the things she had done with Vicky, especially if they knew how much she liked it. She imagined the names they would call her, the things they would whisper about her.

It was early in the morning and the train was mostly empty, to Lydia's relief. She was about to sit down, gratefully, in an empty car when Vicky grabbed her paw and tugged her back up.

"Oh no. Oh no no no you think we're just going to sit here and enjoy the ride, Lydia? C'mon, let's go find a more lively car," Vicky said with a wicked smile.

Lydia tugged back, stopping Vicky.

"No," she said, gritting her teeth as she felt a wave of strangeness flow through her body. She opened her mouth to continue but her jaw clicked shut and her body shook. Saying no to Vicky always made her glitch out. She couldn't resist her mistress, not really, not since Vicky had messed with her code. But she could try. A small part of her thought maybe Vicky might have some mercy. "V-v-," she stuttered, took a deep breath, got her glitches under control, and tried again. "Vicky come on. Isn't getting me in your sex dungeon enough? I don't like doing stuff in public."

Vicky raised a paw and Lydia flinched, thinking Vicky would slap her or claw her. Instead the pichu tickled Lydia under the chin, still smiling widely.

"It's not that you don't like it," she said, in a voice like she was explaining something to a small child. "It's that you're ashamed. Shame is just another kind of pain, Lydia, and you should know by now that I can turn ANY pain into pleasure. So we're going to have a little fun on the way up."

Lydia tried to hold her ground, which only made Vicky smile wider. With her free paw, Vicky tapped some buttons on her watch. Immediately Lydia felt like someone had kicked her right in the stomach. Pleasure so overwhelming it was painful exploded from her crotch. She let out a surprised moan and lost the ability to resist Vicky's tugs. Laughing, Vicky happily pulled Lydia into the next car and pushed her down onto a seat.

"Vicky! What!" Lydia grunted out between clenched teeth.

"Your brand new crotch has all sorts of neat functions. Like you don't even need a vibrator. You've got vibrators planted all up in your vag, cuddled right up with your most sensitive sensors. But I didn't water-proof it all so, well, let's just hope you don't get TOO wet."

Lydia moaned again. It started as pleasure that quickly turned to despair as she turned her head to the side and saw that the train car was occupied. Three cubs, or maybe young teens were sitting further down the car and across the aisle from them. There were two girls - a purrloin and a raboot with her furry red collar - and a boy, a smallish eevee. All three were in school uniforms, probably middle school.

Their age wasn't important, to Lydia. What was important was that they were staring at her. First in surprise, then she saw the purrloin girl whisper something to the other two behind her hand. All three giggled quietly, then the eevee boy piped up, just loud enough to hear: "Do you think she's sick?"

Vicky heard it too. Without looking over her shoulder she rose her voice to make sure the cubs could hear it and said "She's not sick. Just horny." Then she pulled her foot up and planted it right in Lydia's crotch, grinding the balls of her toes into Lydia's clit, which was already swelling up from the powerful vibrations in her vagina.

"Vi-!" Lydia squeaked, then took a deep breath. "Vicky! Please!" She was losing control too much to put on her normal saltiness. She was blushing red under her stripes to the tip of her tail and her eyes were swimming with shameful tears.

"Please what?" Vicky asked, teasing. "Please foot fuck you until you come all over your seat? Can do."

Still twisting the balls of her foot into Lydia's pussy Vicky tweaked her watch, sending even stronger waves pulsing through her. Lydia thrashed as the walls of her vagina began to lube up and the lube slid through carefully placed openings in her skin, soaking down through her rubbery flesh and onto the circut boards below.

Error messages danced in front of her eyes, the text nonsense as her gaze twitched wildly. She let out a sound, uncontrollable, like a bark. Her heels drummed on the floor of the train and her back arched. Ecstacy like burning fire washed through her in strange, fragmented flows that looped and scattered making every nerve and sensor in her skin light up. To call it cumming or orgasming would be an understatement. She had an orgasm cascade, a complete system-wide catastrophic cum that almost shut her down.

When her system recoverd enough for her to feel anything, Lydia realized with alarm that she HADN'T cum all over the bench. Due to the skin-tight latex suit she had on under her clothes, the flood of lube that should have poured out of her was trapped, instead it filled her pussy, again saturating her already sparking vaginal circuits.

"Ooo it's all squishy now," Vicky teased, still massaging Lydia's pussy roughly with her toes. This got a few giggles and an 'dude gross~' from the cubs, who were now completely invested in watching them.

"Vi- Vicky please," Lydia panted. "It's going to short. The electricity can't get out through the latex it's..." She gasped, her vision filling with error messages again, this time they were much more dire than the ones from her orgasm. If she didn't drain the liquid from her crotch she might really fry every circuit south of her stomach.

"Then you'd better unzip and drain yourself," Vicky said, finally withdrawing her foot and stepping aside.

At first Lydia didn't understand, but then she realized the cubs now had a clear view of her. Vicky was saying if she wanted to keep her crotch intact she had to drain her lady cum right in front of their audience.

A breath whined out between Lydia's teeth. But she had little time to hesitate. The warnings were getting even worse, red blinking notices obscuring most of her vision. She swore she could already smell smoke rising from under her skirt.

With a sob she stood, hoping her skirt would cover up at least a little, and reached down to unzip the crotch of the latex suit. Immediately the juice that had built up splattered out onto the floor, making Lydia wince at how loud it was.

"Oh my gosh is she peeing?" one of the cubs whispered loudly and all three giggled again.

As soon as she had relieved the wet pressure Lydia reached down to zip back up but Vicky's paw was on hers in an instant. Vicky wrapped her arms around Lydia, pressing against her. Her paw slid down to lift up Lydia's skirt, giving the cubs an excellent view of what was under the zipper of Lydia's gimp suit. Her fingers teased Lydia's clit playfully.

"Don't you dare zip up," Vicky breathed in Lydia's ear.

The pichu's nimble fingers worked apart Lydia's wet and puffy lips, curling to tickle her g-spot. Her vagina, still vibrating, sucked hungrily on Vicky's fingers, trying to pull her even deeper. Every touch and tease of Lydia's clit sent shivers through her and made her moan.

Between euphoric waves of pleasure from Vicky's aggressive and expert fingering, Lydia realized the cubs watching them had fallen silent. She could feel their gazes focused on her vagina, which was practically bursting out of the zipper of her gimp suit her lips were so swollen. The cubs were even starting to blush, and not in an embarrassed way. Their eyes were starting to get glossed over and she watched as their chests started to move in and out more deeply as their breathing became rougher.

"See?" Vicky whispered so only Lydia could hear. "Everyone in this world really just wants a good fucking. I wouldn't be surprised if they ran home to try some of the stuff I show them today."

Lydia had enough control to get some of her old spirit back. "Okay we've shown them enough, though. Let's wrap it up before they cum in their pants."

She gasped sharply when Vicky flicked her clit painfully.

"Wrap it up? Lydia we're just getting started."

Then Vicky pinched Lydia's clit between two fingers, massaging and squeezing it in a rhythm that made Lydia's head spin again. Vicky's other hand had most of its fingers buried deep in Lydia's pussy, pistoning in and out while curling up to massage her g-spot with every thrust.

Lydia slathered her lube all over Vicky's fingers until it started running down her arms and dripping onto the floor, joining the puddle of Lydia's cum already spreading beneath them, shining in the sunlight that shone in through the train windows.

As her pussy once again flooded the warning windows returned, filling Lydia's gaze. She could feel Vicky's hand twitching as little shocks zapped out of her vaginal walls onto the pichu's hands, but Vicky just leaned into it and shocked right back, sending a painful, numbing rush through Vicky's entire pelvis, making her tail stand straight and her teeth chatter as her head glitched out and her vision flashed warning red.

"Tell me you want it. Say it out loud. Say 'let me cum, Vicky'," Vicky hissed in Lydia's ear, using her electricity to withhold the orgasm. "Let those cubs see how bad you want it."

With her head spinning and errors scrambling her system Lydia didn't have the fight to argue. Caught on the knife edge between searing, unbearable pain and heavenly pleasure she was Vicky's to control.

"P-please let me cum, Vicky," she moaned, weakly.

"Louder! Let those cubs see what a nympho you are. Let them hear how much you like it!"

"Let me cum Vicky! I want to cum! Vicky please! I need it!"

As Lydia howled she felt Vicky release her control and the orgasm hit like a dam breaking. Splashing liquid echoed all through the train car as she added even more of her lady ejaculate to the puddle beneath her. She was weak in the knees, only Vicky's grip on her pussy holding her up as she twitched and gasped and gushed her lube all over the floor and Vicky's paws.

Chuckling, Vicky let Lydia slump onto the bench, which was immediately darkened as Lydia's continue lube leakage soaked it. Through tired, half-closed eyes Lydia watched Vicky lick thirstily at the musky lube coating her arms to the elbow.

Just then the door to the car opened. Vicky and Lydia looked to see who had come on, and Vicky broke out a wide grin.

The woman who stepped into the car was a pikachu. She was the mirror image of Vicky, only older, with the full proportions of an adult.

"Big Vicky," Lydia moaned.

Big Vicky wasn't exactly a clone of Vicky, but she wasn't exactly not either. She was something Vicky had cooked up. She had copied her programming into Big Vicky, so the two of them were almost always in sync, thinking the same things, though they weren't a hive mind. All that mattered from Lydia's perspective was that they were quite the pair for double teaming their sexual partners.

"Good timing," Vicky said. "Lydia's legs were just getting tired from all that hardcore cumming. I think she could use a little break."

From Vicky's tone, Lydia knew she was not about to get an a actual rest. Far from it.

"Well I think we can arrange that," Big Vicky said, matching Vicky's wicked grin. "You shuck off her clothes and I'll get her all nice and comfy."

Lydia didn't have the strength to fight back as Vicky skillfully undid her buttons and slid her out of her shirt and blouse, revealing the black latex suit underneath. Then Big Vicky stepped in and used straps attached to the suit to tie up Lydia's arms. Lifting her up by the arms, Big Vicky hooked Lydia's straps through a handle on the ceiling of the train car. Lydia was just low enough that she could stand on her tip-toes. Her legs were shuddering with the effort of keeping upright.

"Oh, you said her legs were tired, right? Big Vicky said.

"Yep. Better give them a rest," Vicky replied.

Then, quick as a flash, Vicky pushed hard on Lydia's hips. A hidden switch on either side clicked inward, and Vicky twisted. Lydia's legs popped out of their sockets and Big Vicky stooped to pull them off completely and set them aside, leaving Lydia hanging suspended by just her arms from the ceiling of the car.

"H-hey you're not gonna hurt her, right?" the eevee cub piped up. The cubs were wide-eyed now, some of their arousal taken away by the sight of an android being partially disassembled in front of them. Lydia figured they were too innocent yet to see anything sexual about someone being hung from the ceiling and rendered helpless.

Well, they were about to learn.

"Well, the thing is," Vicky said, still smiling. "This girl likes to be hurt. That's what turns her on."

To punctuate this she spanked Lydia sharply, sending ripples through Lydia's huge, rubbery ass cheeks. Lydia yelped, but there was more than pain in the sound.

"She loves it when I tie her up," Vicky continued. Adding another spank, bringing out another yelp.

"She loves it when I pull her parts off." Spank. Yelp.

"She loves it when I spank her and pull her tail." Spank. Yelp.

"She loves it when I fuck her til she can't walk." Spank. Yelp.

"She loves it when I break her and put her back together again." Spank. Moan.

"Sounds like she's ready for another round," Big Vicky said.

"I need a little lubing first," Little Vicky said, pulling off her skirt and sliding down her blue and white striped panties.

Lydia felt Big Vicky rotating her body until she was upside-down, staring right into Little Vicky's waiting pussy.

"Be a good girl and get me ready," Vicky purred, then thrust herself forward, pressing her lower lips against Lydia's upper lips.

At the same time, Lydia felt Big Vicky seize her by the ass, the pikachu's fingers sinking into the plushy rubber of her cheeks, thumbs working in to pull her pussy lips apart.

Two tongues slid into two vaginas simultaneously. Lydia was panting, but she knew Little Vicky enjoyed it when she had trouble catching her breath while eating her out. She was so tired from her massive orgasms that she could barely work her tongue, clumsily lapping at Vicky's clit, spilling saliva into her pussy.

Big Vicky's tongue and cheeks had a constant electric charge, sending random jolts through Lydia's pussy and ass that made her twitch and squeak. The zipper of the gimp suit often got in the way, pressing painfully into the flesh of Lydia's lower lips and tangling in her fur, giving her little painful pinches that sent shivers up and down her spine. It wasn't long before Big Vicky was practically drinking down a steady flow of Lydia's lube.

Little Vicky took Lydia behind the ears and humped against her tongue, rubbing her clit up and down so it tweaked Lydia's nose and lips. Lube began to flow from her vagina and she pressed Lydia's face into it, forcing her to suck it in as it filled her nostrils and mouth enough to nearly choke her. When Little Vicky would pull back Lydia would get a few breaths, coughing to clear her throat of Vicky's thick and musky juice, then Vicky would pull her in for another drink.

When Little Vicky was satisfied with the foreplay the two of them left Lydia dangling there for a bit, coughing and gasping and dripping lube from both ends.

"Please..." Lydia panted. "I'm so tired."

"Shh..." Little Vicky said, pulling a ball gag out of her bag. "Your tongue needs a rest."

Before she strapped it onto Lydia's muzzle she ran her tongue along the inside of it, letting her saliva build up until it leaked out the spit holes in the round gag. When she fitted it into Lydia's mouth, Lydia tasted a sweet, musky flood of Vicky's spit coating her tongue and sliding down her throat.

When Big Vicky pulled her back into an upright dangling position, Lydia glanced over to see what the cubs were doing. Apparently Vicky's speech had calmed their fears for her safety and they were now again watching in fascination as the living porno played out in front of them. She noticed the little eevee boy seemed especially interested. He had squeezed back onto the bench behind the other two so they couldn't see what he was doing and he was sliding a finger up and down against his crotch through his school shorts.

She didn't have much time to focus on him, though, as Big Vicky took control. She had stripped off her skirt and panties and tucked her zig-zagging pikachu tail between her legs, strapping it in place so that it acted like a long strap-on. Grabbing Lydia by the shoulders, Big Vicky pulled her close. Hanging from the ceiling, Lydia was at just the right height for them to be basically pussy to pussy, her puffy lips bursting out of the zipper of her gimp suit to kiss Big Vicky's much larger lower lips.

Lydia moaned as Big Vicky got her tail in place so that it was sawing up and down against both of their clits at the same time. The soft fur and boney structure of the zig-zag tail created a contrast, first tickling then grinding Lydia's clit, sending her through cycles of pleasure and pain.

Then Big Vicky took a tighter grip and Lydia felt a jolt of electricity slam through her as the pikachu gave her some juice through the tail. Lydia was glad of the ball gag since it kept her from clamping her teeth down on her tongue as the voltage set all of her sensors and circuits alight. Big Vicky enjoyed the shock and Lydia's electric shaking. Lydia watched her roll her eyes in ecstacy and lick her lips as Lydia's pussy lips sucked spasmically on the pikachu tail until the electricity finally passed.

Little Vicky was not going to be left out, of course. She produced a strap-on, since her tail wasn't quite big enough to do the job. Lydia felt Vicky slide around behind her, getting up on her tip-toes to ram the strap-on deep into Lydia's pussy. Lydia could just feel Vicky's clit brushing against her tail each time Vicky thrust, and soon both of them were moaning, their lady juices mingling on the shaft of the strap-on.

There was a strange sensation as Little Vicky slid her fingers into the openings where Lydia's legs had been. She worked them in between the layers of rubber and circuitry in Lydia's ass, getting the full effect of Lydia's bulging ass cheeks from the inside. Lydia couldn't see, but she felt Vicky pulling back layers of fur and rubber to sink her hands deeper into the softness, exposing the rounded, gleaming circuits under her ass fat in the process.

Big Vicky seemed to have a similar idea. She unzipped one of the boob zippers on he gimp suit, letting Lydia's massive breast pop out, nipple huge and erect. At first Big Vicky just teased the breast, licking and nipping at the nipple causing Lydia to shiver in pleasure and pain in turns.

Then Big Vicky pushed in and twisted, causing the nipple to pop off and revealing a circular circuit board with a large sensor underneath. Big Vicky squeezed Lydia's breast and turned it upward, letting a long string of spit drip out of her mouth onto the senseitive nipple circuits.

Lydia jerked and shook on her lines as the shock of her breast sensors shorting sent her heart hammering and error messages skimming across her vision.

Through the flashing alerts she saw Big Vicky put Lydia's detached nipple in her mouth and suck on it while she pulled her own plump breast out of her shirt. Bending close, she slid her nipple inside the cavity left by Lydia's. As her nipple touched the shorting nipple sensor plate in Lydia's chest she gasped with pleasure. Sparks spat out from the union of their breasts, Lydia's heaving breaths pushing them together, unintentionally teasing Big Vicky's nipple with each movement.

The stimulation had Lydia's other breast straining against the gimp suit so Big Vicky unzipped that as well, letting it pop free. She teased Lydia's erect nipple with her fingers and then squeezed the breast hard, her fingers sinking in almost as deep as Little Vicky's were in her ass cheeks.

All the while Lydia was being jolted back and forth by the thrusting of the two. Each time she swung back she slid down Little Vicky's strap-on shaft until their pussy lips kissed and she felt Little Vicky's erect clit against her asshole. Then she would rock forward, her clit riding the shocking, bony ridges of Big Vicky's tail.

She would have cum long ago if not for Big Vicky's electricity. The constant voltage being shot into her each time her clit pressed up against the pikachu's tail pushed errors through her sexual systems, locking them in a cycle of painful pleasure that the two Vickys could keep going for as long as they wanted. This was how Lydia's parts always ended up broken. Her electric mistresses were experts at pushing their toys past all limits.
