“What in the heck is that?” Cora asked, looking at the odd shaped mass that seemed to quiver as she approached it.
 “It's called a 'Bio-Milker'. It's brand new, latest technology from the 'Milk Maiden' program. It's supposed to make the milking experience a lot of fun for the volunteer. We haven't had a chance to test it yet, the people from the program are due out here later in the week to make sure it's all functional.”
 “Milk Maiden? What's that Joey?”
 “You haven't heard? I would have thought they'd ask you to volunteer, you, with all that and all,..”
 Cora was looking down at the Bio-Milker, so completely missed Joey's glance down at her exceptionally ample feminine assets, which he'd been hard pressed to keep his eyes off of since she'd arrived.  
 “All what,..?” she asked, looking up at him.
 “All, those,..”
 “Hunh.? I think you'd better explain yourself.”
 Joey gulped and took a deep breath. When he'd heard her voice on the 'phone, asking if was okay to come over, he'd remembered her as the 14 year old girl he used to make out with, when this barn had been filled with hay and bags of feed for the farms livestock.
 Now she was just turned 18, just a few months younger then he, and had come back from Boarding School looking a heck of a lot different.
 They had been each others 'firsts', just before she left on her scholarship. Joey had never seen a girl naked before the night they'd spent wrapped up in sleeping bags, hiding away on the upper deck at the rear of the barn, where he had spent many long days hauling up the bags of feed to load in to the top of the barn. Together they'd watched the stars, waited for the Moon to rise, and then peeled each other out of their clothes ready to learn each others bodies.
 He'd changed a lot, he'd put on muscle from his farm chores, his shoulders had filled out, and he'd shot up to nearly 190cm. More then a few of the girls in his classes had day dreamed about having him fulfil their desires. One or two had even been surprised that their efforts to let him know he could enjoy their youthful bodies went either ignored or unnoticed.
 But when Joey looked at Cora, he was very glad he'd chosen to keep writing to her, and not fool around with the other girls they'd grown up with. She hadn't grown anywhere as near as tall as him, even in the heels she wore, the top of her head had been just under his chin when she had first seen him after getting out of her fathers pick-up, and gleefully jogged the few steps to give him a warm hug.
 'She must have felt my cock twitch' he'd thought, having an instant reaction to just how beautiful she was. The short denim skirt that had climbed up her legs just a little as she slid from the pick-ups seat, sat snugly on her hips curves, topped by a loose fitting sleeveless shirt that did little to cover her ample charms and the bra they looked ready to spill out of with her every step.
 “Stop staring Joey. Back to the here and now. What's this Milk Maiden program?”
 “Sorry,.. It's just, you've changed so much, and I've missed you.”
 “And going by the way one part of you's reacting, it's missed me too.”
 Cora stepped in close, ran the tips of her fingers up over the hard lump in Joey's jeans, before looking up to his face, catching his eyes as they flicked up from looking at where the deep 'U' shaped neckline of her shirt revealed a very large portion of her breasts.
 “They've grown too Joey. That night we spent up there,” she said, glancing up at the top floor of the barn. “That was the last day I wore a B-cup,.. and now I'm an E Ticket ride,..”
 She raised her hand, slid it behind his neck, and pulled his head down a little, as she pulled herself in to him and up on to her tip toes, kissing him deeply.
 His hands found their way to her waist, pulling her forward to almost crush her in to him, and he reveled in the way she felt. They broke for air after a long moment, Joey finding himself looking deep in to her gaze.
 “I,.. I haven't been with anyone since you” he said, almost sheepishly.
 “Not even one girl? Surely the girls in school had interest in you,..”
 “They tried, but I always hoped you'd come back here.”
 “So, then it's a good thing I kept my panties on and my knees together then,..”
 They kissed again, this time knowing they would be sharing their bodies soon enough.
 “So,.. What's this Milk Maiden thing?”
 “Oh,.. So the program, you might not have heard at that private school. There's this company, they wanted to provide healthy natural milk to new-borns and young kids with allergies and in hospitals, and they've gone around to schools recruiting girls to become Milk Maidens. Usually is girls with, well, bodies like yours is now, and who don't have boyfriends. Girls who haven't got any viruses or the like.”
 Cora was watching Joey intently as he spoke, occasionally looking across to the Bio-Milker.
 “So they get the girls to take some hormones that simulate pregnancy effects, so they can make milk, which is then collected and supplied to hospitals for free and sold to consumers with young children.”
 “So how did you end up with this thing?” Cora asked, breaking free of his arms and wandering over to the plant-like device.
 “They've been pretty successful. A lot of the girls at school figured acceptance as a Milk Maiden means they are proving they're virgins and 'pure', so none of the usual gossip sticks, none of the girls providing milk can get called a slut or whatever because the medical tests prove they aren't fooling around with boys.”
 “And some of the less, umm, well, the flatter chested girls realised the hormones for making breasts lactate also make them swell, so they could grow bigger breasts.”
 Joey took a breath, then added, “Well, with all the girls who signed up, the company was having problems getting all the milk from the girls, getting it packaged and stored safely. So they turned to some of us local dairy farmers, to see if we could advise them better practises with our experiences.”
 “So we helped get them sorted with the shipping and storage, but they were still looking for ways that would let the girls provide the milk easier then the hand held suction pump devices.”
 Joey looked down at the Bio-Milker from where he stood next to Cora.
 “A couple of weeks ago, this inventor up north said he'd come up with a way of letting the girls provide their milk, that would be clean, efficient, practical, and probably more enjoyable then having a girl squeeze her breasts into a plastic cup with a vacuum pump on the other end.”
 “So this is one of those machines?” Cora asked.
 “This is 'the' machine. Dad volunteered us to be the test facility for the surrounding counties, and since there are four high schools under an hours drive from the farm, and another 3 less then half an hour more, we got the nod to be the test location.”
 “From tomorrow, there will be a couple of volunteers turning up to help get it all set up, and then from next Monday, girls will be able to stop past before or after school while the company runs a trial program, to see if the Bio-Milker is effective, efficient, and if the girls are comfortable using it.”
 Maybe it was having spent so much time away from boys. Maybe it was the feelings stirring in her heart, or maybe it was something stirring deep in her hips, but something gave Cora a naughty idea.
 “So,.. then no one has used it yet?”
 “Nope. Dad and I un-crated it this morning, he's gone in to town for a farmers association meeting while I've finished bolting down it's frame and checking all the pipes are connected correctly.”
 “Hmmmm,..”
 Cora gave her best 'demure thinking pose', twisting one knee inwards and lifting the heel of her foot, canting her hip sideways a little, and looking down at her body before looking up to Joey with a cheeky grin.
 “Would you,.. can I be, like, first?”
 “What,.?”
 “You know, be the first girl to try it. Before anyone else. You could take some photos and I could pose, and then afterwards, we can go back up to the balcony, and pick up where we left off,...”
 “I don't know Cora. You're not part of the program, how would you make milk?”
 “I wouldn't. So there won't be any sign of the machine being used,.. It'll just look like you ran it while checking your work with the pipes was right.”
 “Maybe,..”
 The truth was, Joey was no longer thinking with the larger of his two heads, just with the one struggling to push against the buttons of his jeans. The dream of getting Cora up on the balcony again was really all the motivation he needed, her logic about testing the machine was more then he could comprehend while he thought about her luscious figure, that he very much wanted to get naked.
 “Here, use my phone, we can start by you taking some photos while I strip off for you,..”
 Joey took the device, and tried to concentrate, tapping the screen several times while Cora teased pulling her top off, posing provocatively in several spots around the new bio-machine. She was about to kneel down to 'examine' the stimulation probes when she had another thought.
 “Hey, where's your phone?”
Joey responded by pulling it out of the back pocket of his uncomfortably tight jeans.
 “Right, set it up somewhere,.. over there on the shelf, side on to this thing, it can record video while we fool about.”
 Joey did as told, and was about to hit record when he felt her arms around him and her breasts pushing in to his back, her head laid against his spine. He jumped as her right hand firmly gripped his shaft through his jeans and pulled against it.
 “Joey, once I'm on it, if, you know, I find a cock in front of my face, I'll just have to suck on it till I'm filled with cum. Okay?”
 “Yeah, sure Cora,..” he replied nervously.
 “Okay, is it recording?”
 “About to be.”
 “Wait, let me go back out of the way, I'll walk in once you hit record.”
 “Sure.”
 He nodded once his phone was recording, and made sure he was out of the way of it, taking photos as Cora walked backed up to the prototype and played at examining it closely. She stroked sections and slid her hands across sections, and then, while playing with a simulator probe, Joey turned the machine on, making sections of it wiggle and grasp out.
 “Oh,..” Cora tittered. “Look at how naughty it looks,..”
 She sighed and let some of the pleasure probes on the ends of their snake-like arms, slip under the hem of her skirt, while she writhed a little and pulled her top up over her head. She laughed and tossed it as hard as she could, sending it sailing out of the room, neither of them aware it caught in the breeze coming in through the barns main doors, and was carried straight on to the horns of the breeding bull, the animal tearing and stomping to be rid of it.
 More of the probes began to snake around her limbs, gently pushing her towards the mounting pads as Cora flicked open the buttons on her mini skirt. She tossed it the way the top went with a laugh, feeling like she was so daring. The skirt was grabbed by Joey's hunting dogs, who chased each other about, tearing at the denim. In moments there was less of it remaining then the top, and the dogs were looking for the next plaything.
 Cora's bra landing on one of the dogs head, didn't stand a chance.
 Neither did her tiny knickers, but it's wasn't the animals that destroyed it. She yelped in surprise as the probes that had wrapped around her legs moved in and under the garment, stretching it until the thin band around her hips and between her legs both snapped, and it flew off the side of her hips.
 She turned a little to look where it went, and found herself pulled back to the machine, one of the probes now wrapped around her arm, pulling her over on to it. Before Cora or Joey fully realised what was happening, the entire set of probes and their snake-like arms, had encircled her wrists, waist, and thighs, and she was being lifted.
 In the barest of instants, Cora was spread out above the pads, then lowered, her large breasts dropping neatly in to the vacuum cups designed to keep the soft flesh in place as the suction pumps ran up to speed.
 “Oh, oh! , OH, ow, ow!, ow! Owowowowowow,... gurk!”
Cora was just about halfway from undignified hurt to horrified scream when a further probe popped square in to her mouth, nearly making her gag. The horror doubled when another probe buried itself deep in to her pussy.
 That was the point when Joey realised there might be something more sinister to the machine, and moved to slap a hand down on the emergency stop button, but stopping himself bare millimetres above the large red half dome. Looking back to the naked figure before him, watching as her breasts were sucked on by repeating pulses of the vacuum pumps, he was curious to see what would happen, wondering 'Is this what all the girls will go through?'
 The look on Cora's face told him she was panicking, the flexing of arms and legs against the writhing limbs of the machine told him she wanted off it, and the power to release her was all his. And he was really enjoying watching what she was enduring.
 Her eye looked frantically between his hand and his face, confusion over why he wasn't saving her evident on her face, right up until she reacted in fear as she felt another of the probes slipping over her exposed butt and zeroing in on the one remaining hole they hadn't filled. Wriggling and shaking her hips did nothing to discourage it, but instead cause the machine to push harder with the probe buried in her pussy.
 'I saved that for him,...' she thought, her dreams of sitting astride Joey's cock once more seeming torn apart even more then her discarded clothing.
For his part, Joey was still taking photos on her phone, moving to catch the moment the final probe pushed it's way in to her anus, then moving to her face to catch her tears and the black drips as her mascara ran down her cheeks. He noted that the probe pushing past her lips had continued to force it's way down her throat, and he was curious about what it was to be used for.
 “Breath through your nose Cora. I know it's not what either of us expected, but it's probably best to let the machine run it's course, before we let any of the Milk Maidens try it. What if it was to damage their ability to make milk for all those babies that need it?”
 Cora tried to cry out for him to save her, but with the probe now just about to her stomach, she could barely stop convulsing as her body reacted autonomously, trying to push the probe back out. She could feel it wriggle, and the same for the one that was now pushing deep in to her gut as it coiled and slithered, following her bowels from the insides.
 A whirring noise started deeper in the machine, to accompany the pulsed wheezes as the pumps kept trying to pull milk from her breasts. The new noise was followed by a ripple along the piping and then in to the tentacle like probes, before she suddenly felt a warmth deep in her gut, and her stomach started to swell.
 “It says 'Cleansing cycle' on the screen,” Joey read out. “Above that it says 'New Milker Initiation'. I think it may have figured out you're not making milk, so is doing stuff to switch on your breasts.”
 Turning back to Cora, he could see her belly was now stretched and bloated, and the probe at her rear was slowly pulling back, right up until the tip of it had pulled back to the insides of her sphincter muscle, and expanded inside her. There was a beep from the screen, and the display changed.
 “It says 'rectal outflow pump active', and 'Oral pump high speed'.
 If Cora had been wide-eyed before, she was now in full panic, eyes as wide open as they could be, warm fluid pumping in through her stomach and flushing her gut, to be sucked out the rear of her body. The pulse waves of the flow seeming to match the timing of the vaginal probe, as it wriggled and vibrated and thrusted.
 Her eyes rolled back as the combination of sensations went from disturbing to confusing, and then to deeply pleasurable as that last probe worked it's way deep inside her sex.
 What she completely missed was the spray from the tip of it, first a lubricant, then once its pointed tip had tickled open her cervix, a second spray, this time laden with hormones and mood altering supplements, delivered directly to the blood vessel filled womb, and quickly absorbed in to the flesh.
 Changing shape to me more like a human penis as it retracted, the probe switched to thrusting in and out much like what Joey wanted to be doing to her.
 “Now it says 'cleansing complete. Nutrient cycle started'. Looks like it's feeding you something. I really should have finished reading the manual,..”
 Joey took more photos, including close ups of the two probes in her hips, making sure to show her pussy and the deep pink colour of her arousal as blood filled the tissues under the skin there. He noticed the probe at her mouth starting to retract, a glance to the control screen and he read 'Conversion complete, new Maiden initialised. Milk production within seven days'. “Looks like you're going to be the first Milk Maiden after all Cora.”
 She groaned, her head flopping down loosely after the probe extracted itself from her mouth. She quickly began to grunt in time to the vaginal probes thrusts, interrupted by a yip and exclamation as the anal probe pulled itself out, leaving the opening to slowly close down, a little of what ever had been pumped through her dripping out and on to the floor.
 Swapping her phone over to video, Joey got some closer shots of her face as the remaining probe began to move faster, lubricant squirting out of it, and Cora beginning a keening wail as the stimulation became her whole world. She never noticed when the suction cups dropped free of her large breasts, but Joey did, quickly moving the phone around to catch them swinging about in cycles matched to the thrusting probe.
 Her head came up and her body convulsed as she screamed out a nearly animal reaction to the stimulation. Whether she wanted to or not, an orgasm rippled through her body, triggering autonomous responses, her toes curling, legs flexing and gut muscles squeezing, right up to where she passed out.
 “Hmmm, says 'cycle finished', sounds like it's powering down.”
 Turning his head back to her, Joey noted the machine was returning to the state it had been resting in before he'd switched it on. “Better copy these videos and photos over before you wake up” he said to the now unconscious teenager. “I reckon they could make us all some money later.”
 Cora only began to wake as Joey was carrying her upstairs to the barns new attic, a private space where they had installed a few computers to manage the new milking hardware.
 “Jo-eey,... why didn't you stop it,...” she slurred out, still barely able to think, and certainly not ready to move.
 “Needed to see what it was doing, and find out why. Now I know, that if a girl whose not lactating gets on, she gets cleaned out and converted to milk maiden. I'm betting if you'd had any STD's or such, it would have rejected you. I'll need to read the manual and see what it does to a girl then.”
 “Converted,...?”
 “Yeah, you'll be making milk pretty soon.”
 “But, I wanted you to fuck me, and you didn't save me,...”
 “Yeah, but now I get to keep you.”
 “Keep me?”
 “Yep.”
 “I don't understand.”
 “It's in the manual, I checked while you were asleep on the barn floor. Dad checked with the lawyers too, and your father had a read too, he was gonna object, till he saw the video of you climbing on to the machine freely, he said 'her ass, she done with it what she wanted, so she's got to go through with it'.”
 “What do you mean?” Cora asked, gently standing as Joey shifted to lower her feet to the new wooden floor of the attic. She wasn't ready, or recovered enough to react, when he pulled her hands behind her and she found herself suddenly trussed by a rope around her elbows.
 “Joey! What are you,..?”
 “You climbed on the machine by yourself, and you got converted to full time Milk Maiden. It's all legal, and now I got to look after you and keep you safe and secured, and in a weeks time your tit's will be swollen and we'll start milking you for real.”
 “Joey! No! I want to go home now! Where are my clothes?! Let me go!”
 “Nope. Can't. The Bull and the Dogs got your clothes when you threw them at the animals, so they're all torn up. And I'm responsible for you now, so you're staying here, where you can't run off and get hurt and damage those tit's of yours.”
 Cora struggled as he pushed her backwards a few steps, then tried to wriggle out of his grasp as he tied the rope off to one of the roof beams. She kept struggling as he tied her wrists as well, so she couldn't undo any of the knots and run off.
 “Joey, please, baby, don't you want to, with me in the moonlight,...” she begged, changing tack and trying to wile her way out.
 He was gentle, lifting one hand to her cheek and tilting her face to his, “Babe, sure, and I love you too. But I can't fuck you like we wanted, we're stuck with this because we were both stupid and didn't read the manual.”
 Turning, he walked back towards the new stairs, turning at the top to say “Don't worry, I know just how to get you some friends to enjoy this with, and just which girls at school are going to make a perfect herd of girl-cows.”
