Watermelon sized breasts that produce gallons of aphrodisiac milk simply do not exist, and there are sex scenes in here that would frankly be incredibly painful if they were to occur in reality, but are a regular part of much fantasy erotica. So I advise you to suspend your disbelief, and if breast enlargement, bondage, milking, futanari, huge cocks, tiny cocks, alien sex, alien impregnation, massive semen production, gang bangs, triple penetration and tentacle sex is not your thing, then read no further. Cheers! Sylver ***** Tonight was the night. I'd found the right mistress to help me perform the operation. The price was one I was more than willing to pay as well; willing submissive servitude and twice daily milkings of my new assets for 3 months. I would have my breasts enhanced. They're already a lovely C-cup, and I've been working them with suction cups and massages. My nipples are like long erasers now, pink and pointy and I could sometimes even squeeze a few drops of milk from them. With the enhancement, there's no telling how large my boobs would become as they filled with what I hoped would be cups of genetically modified, aphrodisiac milk. It seemed like the process created different results for each woman. I'd been following some of my favorite celebrities--called milk-maids-- and they develop mammaries from a D-cup to water-melon sizes. Their pillowy mounds could produce up to a gallon of milk a day, more if they were being sexually stimulated. So of course they were. It was a lucrative career, as not only could the milk produced be sold at a premium but men and down both paid to have sex with them. All humans, of course. Interspecies sex wasn't forbidden except for with milkmaids, as the aphrodisiac effects were mild on humans, but could cause adverse reactions in other extra-planetary species. My new mistress, one of the rare natural futa that had started being born with increasing regularity in past couple centuries, is a renowned researcher in various sexual modifications. She has a new serum she's been experimenting with and now she is exploring administering it in various ways. I'm test subject number 4, codename kitten. ...... I waited on a kneeling cushion in the corner of my mistress's dungeon room. The floors were bamboo wood scattered with cushions around the various props set up in the corners and by the walls. There were 3 or 4 people going about various quiet activities. I wanted to look, but after I'd been led to the cushion I'd been instructed to keep my eyes lowered. I was naked, my arms folded behind my back and my nipples hard and pointing from my round breasts. My shaven mound was already soaked from the anticipation I'd been feeling all day. I was afraid I'd start dripping on the lovely red silk beneath me at any moment. A pair of shiny black heels stopped in front of me. My mistress. I recognized them from earlier. A crop under my chin lifted my face to look at her. My eyes raised, taking in her pin striped pencil skirt and deep blue blouse. She'd also added a lab coat, opened and flowing around her to her knees. "Lovely!" she exclaimed, as I met her dark eyes set in a chiseled face. "You'll be a perfect first test candidate for my new theory. Good proportions- slender waist, large buttocks, average boobs. And such a pretty face, with those big blue eyes...a shame your matching hair had to be shorn. A legacy of your mother's? A renowned courtesan in her time. Well it would have fallen out during the procedure, but it will grow back in about a month. Come now, up! I'm eager to get started." With that she tapped me on the buttock with her crop, using it to steer me across the room to the contraption that stood in the middle of the floor. My eyes puzzled over it. On a slightly elevated platform there was a box made of steel rods to support various straps. There on the floor before it was a cushion to kneel on. Two medical bags on either side of the box held electric blue viscous liquid. Tubing ran from the bags to a couple of suction cups positioned upright on the floor inside the box frame. "Here you go, kitten. Let's get you set up," my mistress directed me to kneel on the cushion in front of the box. "First, in goes the gag, which will also help us monitor your levels of pain and arousal. Red is pain, blue is arousal, purple is a good mix of both." She held out a short thick phallus, and pointed to the base where a large light glowed white. She put it in my mouth-- it stretched my mouth almost to the point of discomfort and curved slightly downward as it slid over my tongue and to the back of my throat-- not enough to cut off my air completely, but uncomfortably close. She adjusted the straps to keep it in my mouth. "There we go! Glowing a nice lovely blue already, I see. And glowing brighter by the moment, too -- you like having your mouth fucked by a big cock, do you? Gagging a bit as well? Oh yes, that definitely got quite a bit brighter." My eyes started tearing in humiliation, but I arousal swept over me as well. "Next, let's keep your arms out of the way, shall we?" With a deft bit of ropework she tied my arms to stay where they were crossed behind my back. She did something to tighten the rope and my breasts jutted forward even further than they already were. "There's a lovely girl. My good kitten," she petted my hair and tweaked my rock-hard nipples. "After tonight you'll be fitted with a harness and all procedures will be carried out in a proper lab, but I like a little bit of showmanship. The first experiment is always recorded, you know. So, I think you'll enjoy this quite a bit my dear. Now bend over this strap here," she bent me over the first strap suspended in the frame box and tightened it so my hips were lifted and buttocks exposed. More straps held my thighs open. Now as I looked down I could see my boobs were almost directly over the suction cups I'd seen earlier. She settled my shoulders into another strap so I was fully bent over and partially suspended above the suction cups. My chin was held in yet another strap to keep my face looking forward and my back arched. My breasts felt heavy below me and the only thing I could see was the floor and wall in front of me. The straps allowed me to move a bit forward and backward and side to side, but the shape of the box meant it wasn't a lot of movement. "Let's go ahead and get the blood flowing. We'll want your mammary tissue ready to accept the treatment as fully as possible." She fitted the suction cups over each breast entirely and flipped a switch. The phallus in my mouth muffled the tiny shriek I gave as both breasts were sucked into the cups. I groaned-- it felt like both of my boobs had been engulfed by a great sucking mouth! "Oh yes, lovely--is that a tiny bit of purple showing up? Very good. And getting so very wet." I felt a hand follow some of the wetness from my thigh up to my pussy. I wriggled and tried to spread my thighs further as I invited her hand to play with me. I felt as if my pussy was already gaping, hungry for a thick cock to fill it. Her hand dipped into the wetness at my center and I groaned, trying to thrust myself onto her fingers. She spread my fluids upwards and around my asshole. "I'm also going to add a monitor here, my kitten." Her fingers played with my puckered hole, "You can't expect me to be watching you from the front the entire time, now can you?" A hard smooth shape replaced her fingers and started pressing into my back door. She wiggled it back and forth and fucked me in tiny movements, slowly inserting a gradually widening object. A tiny bit at a time it stretched me more and more until my anus burned. Abruptly, the toy narrowed so quickly it popped in. I moaned and shifted, feeling the buttplug's heavy weight stretching out that delicate hole. My juices were flowing down my thighs for sure now. "Wonderful, my dear. You're doing so well. And a good bit more purple in the mix now-- your anal monitor is definitely doing both it's jobs well," she chuckled. "First we need to calibrate your pleasure threshold. Let's go ahead and give you an orgasm, shall we?" I moaned and shifted my hips back. My boobs felt swollen and deliciously tender from the suctioning. My pussy ached to be filled, gaping and waiting for a big fat cock to push into me and fill me with sperm. "Aziz! Come over here and fuck my experiment for me, there's a dear." I heard a man's tread and pushed back again in anticipation as I felt someone come up behind me. The smoothness of a cockhead rubbed itself up and down my slit and then slid into my entrance. Instead of a fat cock, though, I felt a finger, or something the width and depth of a finger. I felt thighs and balls slapping me, and groans as the man behind me pumped away at me with his tiny cock. I groaned, needing more as my pussy desperately tried to suck in whatever it could of that small dick. I could barely feel him! Still, his balls were slapping my clitoris and I could feel an orgasm approaching even with the tiny extra stimulation he was providing. I whimpered behind my gag, desperate for more to push me into orgasm. "Hmm, far too much blue right now," my mistress said and suddenly the suction at my breasts increased. I moaned against the gag as my breasts felt like they'd ballooned. Aziz, the man frantically pumping me with his inadequate cock, started gasping. He came, growing just a tiny bit harder and thicker, just enough to push me over into orgasm. I squealed against the thick plug in my mouth and my anus and tits throbbed while my pussy sucked and sucked at his sperm rushing into me. I sagged, momentarily replete. "Good, good! We got a nice pure bright blue there. Aziz, clean up your spunk from her pussy with your tongue and then go back to scrubbing the bathroom. Now on to the next phase." Aziz started lapping and sucking at my pussy, providing a tiny bit of pleasure from the mounting pain that was starting to center on my swollen and abused breasts as my orgasm faded. My mistress turned off the pumps and removed them from my breasts. I groaned as I felt relief from the suction cups. "Now, before we get to the main event, we need to test your pain threshholds" my mistress explained as she held two smaller suction cups to my aching nipples and breasts. "I can tell by the faint pink glow coming from your monitor that you've tipped out of arousal. Your breasts must be hurting quite a bit. Don't worry, dear, they'll be hurting far worse when I'm through with you." Oddly, her words aroused a tiny spark in me and I groaned. She chuckled again. "Well that's interesting. You just flickered from pink to blue and back-- no purple at all. Very interesting." She turned on the pump again and a slow sharp pain started in my nipples as they were sucked into the cups, elongating then as they filled the cup. "Oh yes, my little kitten likes having her nipples sucked. It hurts so sweetly, doesn't it?" I groaned. My nipples felt like someone was running a match over them. The mistress reached over and with one finger wiped up a bit of drool running from my mouth. "You're a very messy kitten. I think you need punishing." She moved behind me and I felt her smooth hands cupping my buttcheeks then running her nails along them. She alternated, grabbing and squeezing, then smoothing them again. The pain in my nipples receded as my focus switched to her handling of my ass. She separated my cheeks and I felt a tongue dip into my snatch and lap at some of the juices once again overflowing me. "Very, very dirty", she said and spanked me sharply. Once. Twice. Then smoothing with the hands. Then more spanking, followed by a light caressing. Again and again she alternated between soothing and spanking, each time spanking a few more times and a little harder until I was losing count. It felt good-- my ass felt warm and my pussy was dripping again. Each spank jiggled the buttplug and made my breasts bounce and my nipples ache in pleasure and pain again. I arched, trying to get my buttocks higher, inviting her to spank me and touch me. Which she did. Over and over. Soon, though, the pleasure reached its peak but the pain kept building. I started wriggling my ass away from her hands instead of seeking them, as I tried to lessen the stings and distribute the pain to less sore parts of my cheeks. "Oh yes," mistress said between smacks of her hand, "the purple is fading fast now and your ass is looking almost as bright a red as your monitor." She gave one final hard "WHAAP, WHAAP" on both cheeks and I squeeled and gave a small sob. She soothed my cheeks with her hand. "Good girl. You did excellent. Much better than I had hoped. With that kind of pain tolerance, we'll be able to enhance you close to the maximum. I can't wait to see the results." I whimpered quietly around the cock in my mouth. "Amilia! Come take care of my new pet while I make final preparations." I heard a soft murmur and then felt someone position themselves under me and between my thighs. Adjustments were made and that someone, Amilia I supposed, started licking at my clit and pussy. "That's right, eat up all her sweet juices. Bring her up slowly and get her close to her peak, but don't let her go over. Tongue only--no fingers in her snatch. That will be for me," my mistress gave a soft laugh and moved away, doing something with the tubes and bags. Amilia was very skilled and slowly the soreness in my ass faded. The suction on my nipples started to become bearable and was easing back into a pleasurable sort of pain as well. As the mistress did various incomprehensible things around me, I started moving more insistently against the mouth below me, trying to aim Amilia's agile tongue more firmly against my clit or to penetrate my achingly empty cunt. Vaguely I was aware that my mistress had moved beside me. She unsnapped my gag and slowly removed it. "As delightful as you look, my dear, I find I need a bit of warming up before I fuck your tight snatch. And I simply can't wait to see your mouth stretched around me. Open wide." My mistress moved in front of me and I gasped as I saw her huge semi-aroused cock. I marveled that she could have hidden its bulge beneath her skirt. If Aziz had been disappointingly small, then my mistress made up for it by being intimidatingly large. I wet my lips and she lifted her cock to my mouth, feeding me just the head at first. I moaned as I flicked my tongue into the slit and tasted a single drop of her cream. I started sucking in earnest, wanting to taste more, my tongue swirling around the plum sized head. She gave a small sigh as her fingers cradled the back of my skull and pushed in deeper. My mouth stretched and my jaw ached as I fought to take her width. She held my head still and started fucking my mouth, a little deeper each time until I could only breath between strokes. Her precum was flowing into my mouth now, and she started hardening even more, stretching my jaws wider than I'd thought possible. Each time she drew almost out I flicked my tongue against her slit, sucking out a little more of her sweet jizz. She moaned when I did this and I rolled my eyes up. Her head was tossed back, framed by her melon sized tits and proudly jutting nipples. She glanced down and caught me looking. She smiled. "About time I think. It sounds like Amilia is about to drown in your juices, my pet. And you are far too skilled with that mouth of yours!" She thrust her now rock hard cock as deep as she could and held my head there. I fought to keep from gagging, and then fought the growing urge to breath as she choked me with her fat cock. I started to wriggle and she finally relented, pulling from my face and trailing a long rope of jizz and saliva. I gasped to breathe. "I told you the rules about where to keep your eyes, my dear. But please, feel free to break them any time," she laughed, and strapped my monitor back in place. After her cock, it was a welcome relief. My attention turned again to what was happening to my own body. My nipples ached in a delicious fashion as did my anus, but my pussy ached with emptiness as Amilia maintained her teasing assault on my clit. I moaned and writhed in my bonds. "Oh yes, you are a bright violet now. Perhaps a little on the blue side but that will change before too long." She flipped a switch and the pumps at my nipples worked harder. I gasped and moaned, the pleasure and pain mingling as my nipples were abused. "Now my pet, I'm going to fuck you good and long and hard and deep until your monitors are glowing mostly with blue and then right as you're teetering into orgasm I'm going to press the button in my hand. That will trigger the needles in the suction cups to pierce through your nipples and deep into your mammary tissue. From there the enhancement fluid will start filling your breasts. If we've got your pain and pleasure meters calibrated correctly, this should cause a long hard orgasm from you. Are you ready my kitten?" With that she rubbed the fat head of her cock up and down against my soaked slit. I tried to show my willingness by groaning and rocking back against it, attempting to force that plump, slick cock into my aching pussy. "Good girl. Amilia, hold off your licking until I give the word. Then I want you to suck and flick her clit as hard as you can. Now my pet, let's see how tight your pretty pussy is." With that she pushed into my opening and I pushed back, my tight vagina slowly giving way to her slick thick cock. I gasped around my gag as she finally popped the head in. It felt so good! So amazing. I'd never felt so full, with my mouth and ass and now pussy stretched to bursting as she slid in further and further. She was so big! "Oh yes my dear. So hot and tight. That's a good girl, take my cock. Suck it down with your hungry pussy." She hit bottom and began pulling out. She teased me by leaving just the head inside. I tried to rock back to get her to fill me again, but she wouldn't let me. Soon I was sobbing and rocking in my bonds, my pussy fluttering as I tried to suck her cock back into me. "You want this my dear? Then you shall have it." She slammed back into me and I screamed in ecstasy around my gag. She fucked me. Hard and fast and deep. I wailed against my gag as my tender breasts bounced, held in place by the cups sucking hard at my nipples. Each bounce caused a little more pain which my body just added to the pleasure, along with my burning anus as the butt plug was jostled by each movement. I felt myself approaching orgasm as her thick cock stretched me almost unbearably, reaching far into my depths, stretching me wider and deeper. "Now Amilia!" My mistress cried in a strained voice. My clit was suddenly attacked by a vicious mouth and I screamed in my throat as I felt myself sent toward the edge. A click, and then excruciating pain as my nipples were simultaneously pierced. Everything turned white and I pitched into orgasm. Waves of pleasure and pain washed over me as I felt my mistress roar and let loose her massive load deep inside me, her cock pulsing larger until I felt like I'd break... If my boobs didn't burst first. My boobs felt like they were on fire as each pulse of the enhancement device sent blue liquid rushing into them. While each pulse was excruciating it still caused a wave of orgasm over me. They were swelling and growing heavier. Each tiny movement from my mistress and Amilia's mouth sent another wave through me. I could feel my pussy pulsing as it drank in load after load of my Mistress's sperm until it started leaking out and running into Amilia's eager face, still lapping at my swollen clit. The last of the blue liquid was drained into my heavy swollen breasts and with that the orgasm finally stopped. The needles and suction cups retracted abruptly and I sobbed around the cock in my mouth with the sudden relief. All parts of me throbbed -- my pussy with the last waves of pleasure and my nipples in burning pain. Enhancement: Experiment Ch. 01 Slowly, my mistress removed her cock from me. The head came out with a wet pop, leaving me empty. I hung limply in my bonds, exhausted. The pleasure was fading fast. My heavy breasts throbbed in time with my heart beat and were echoed by sharp pains in my nipples. My mistress directed Amelia to loosen my bonds and help me recover in my quarters. "Very successful so far." My mistress, now in a silky robe, moved in front of me to help remove my gag. "I can't wait to study the results. I have many theories about what will happen once you recover and the process is complete. Will your boobs be larger than average? Produce more milk? Perhaps only produce when you're orgasming, or perhaps you'll orgasm constantly while you're milked. At the least I expect you'll produce far more milk while you're aroused than most milk maids. And I'm sure there are side effects I won't have predicted." She cupped my face in one hand and wiped the tears from my cheeks with her thumb. "Now rest for 24 hours and eat as much of whatever you like. Your body will make demands of you as it adjusts and accepts the changes. No touching yourself to arouse or orgasms unless you have my permission." I nodded and forced my roughened throat to whisper "yes mistress." "Good pet. You'll make a lovely addition to my stable." With that she smiled and walked out of her dungeon, leaving me sore and aching in the hands of Amilia. I don't remember much of the next 24 hours. I know Amelia unstrapped me and led me to my room, but after that all was darkness. -- Enhancement: Experiment Ch. 02 I came slowly and reluctantly awake - I had been dreaming that I was being fucked by several men with huge cocks while my boobs were being sucked and milked. I sighed at the sexy dream and started to move my hand down to my soaked pussy. This small movement jostled my tender breasts and set them to thrumming. I awoke fully. Memory came back to me and I flung off my sheet and sat up to look at my new assets. They were amazing! The size of small melons, and my nipples had gotten longer as well, almost the size of my pinkies. I cupped them and they overflowed my hands. I lightly pinched my nipples and a wave of arousal swept over me. I quickly jerked my hands away, remembering that my mistress had warned me I wasn't allowed to play with myself. My nipples still throbbed from that light touch, though, feeling full and aching. And they were leaking! Bluish white fluid was pearling on the tips. I brought a breast up and touched my tongue to it. It was creamy and sweet. I brought the other breast up to do the same. Of course, at that exact moment my mistress walked in. "Kitten!" my mistress exclaimed as she witnessed my offense. I dropped my boobs and winced as their heavy weight bounced on my chest. "None of that! I won't have you spoiling my preliminary data. Now attend!" She brought her ever present crop around and pointed it at the floor. I scrambled out of bed and stood where she pointed, arms folded behind my back, eyes down. "Come now, we've got a lot of measurements to take today." Her crop tapped me on the ass as she guided me out the door and down the hall. I kept my eyes demurely lowered to the elegant wood floors, letting her guide me past rice-paper sliding doors- her home had a distinctly Japanese feel to it. The mistress herself was wearing a silky long black kimono patterned with red and gold dragons, her wasp-like waist adorned by a gold obi to keep it shut. I, however, was completely nude, although I didn't feel naked. I was too fascinated by the bouncing of my new breasts, how the nipples pointed crazily with each jiggle. "Here we are my dear. In here. Amilia and Jerome will help me with your measurements and then they'll clean you up and bring you to the milking room after I've got it set up. Jerome, take up the calipers for me. Amilia, you'll take notes." The room I was in was tiled in white and partitioned with three low half walls to make four stalls. Each had different nozzles and sinks and metal railings to make me think they each had separate purposes. Amilia and Jerome stepped forward from where they'd been standing by the rightmost tiled half wall. My quick glimpses as they moved about their tasks let me see that they were both somewhat clothed in open lab coats and the ever present collars of the subservients and nothing else. Amilia, who had aided me last night, was small and petite with pert little breasts and dark pink nipples. Her hair was a luscious dark brown that was caught in a low bun- part of her costume as lab assistant I supposed. Jerome had the same toffee skin tone and dark hair caught in a similar bun, but he was anything but petite. He was as tall as the mistress and his broad shoulders strained the seams of his lab coat. His limp cock was even larger than the Mistress's and his balls were huge, each one the size of an avocado. Jerome seemed indifferent with his measuring as the mistress directed him, but with my eyes lowered I could easily watch as his thick cock started stiffening each time he had to touch me. By the time the mistress had finished he was hard as a rock and had to take care not to brush his monster cock against me. I was getting wet just looking at it. He let his hands linger just a little too long with the last measurement. "Well, Jerome. I see you appreciate our fine new little milkmaid. Her tits are already larger than mine, and I expect they'll grow until she reaches her peak milk production. Of course I haven't let you cum in days now. I bet your balls are about to burst, if that precum you're leaking is any indication. Well, let's take some measurements to see if your enforced abstinence will yield the results I've been expecting. Grab hold of that bar by the half wall and present yourself. Amilia, remove his monitor and see to his lubing. Kitten," she looked at me as she parted her kimono to reveal her long thick phallus. " Hmm, while normally I would love to have your expert little mouth on me, semen has been known to increase milk production and I don't want to skew the results of your first milking. Stand by the wall and watch, there's a pet. " I did as she said, my eyes drinking in the scene. Jerome had disrobed and was magnificent. Bending over to clutch the metal bar revealed a bright glowing blue-violet monitor in his tight muscled ass, which Amilia set to remove and replace with her fingers as she lubed his slightly gaping hole. The mistress was working her own cock with her hand and hardening it to magnificent proportions. I salivated looking at it, remembering it's exquisite taste as it filled my mouth and throat. "Good, Amilia. Go get the liter beaker from the cabinet and kneel under him to catch his sperm. Under no circumstances are you allowed to taste it! The latest serum I've given him may have changed its composition. I'll need to study it before I allow him to share it with anyone. There you go. Hold his cock in place with your other hand- I want to be sure we catch all of his spunk." The mistress had moved behind Jerome and was slowly rubbing her cock head up and down his crack as she instructed Amilia. Once the sub was in place, the mistress placed the thick head of her shaft at Jerome's entrance and leaned forward. I watched Jerome as he braced himself. His face had a look of concentration and he gave a slight groan as the mistress stretched the tight ring of his sphincter with her cock. "There's a good lad. Let me in, just a little more," the mistress murmured as she slowly pushed into him, one hand on his hip, the other helping her cock push past his tight ring. You could almost hear the pop as her head made it past. Jerome let out another groan as the mistress praised him and fed the rest of her thick length into him, inch by slow inch. "There's my lovely lad. Your tight ass just wants to suck my cock all the way in. But your hungry hole will just have to wait. There we go, a little more. So nice and tight around your mistress's cock." The Mistress's voice held only a hint of strain while Jerome was panting, his head thrown back and his face awash with a mixture of pleasure and pain. His cock was purple and as big as a stallion's, swollen with blood. Already a steady drizzle of precum was drooling into the beaker Amilia held under his juicy cock. The mistress moved her other hand to his hip as the last couple inches of her cock worked their stay way into his tight hole. With only an inch or so left, she grabbed his hips and slammed home. Jerome grunted and small burst of jizz squirted from his cock. "Oh yes, my darling, you like that don't you," my mistress murmured and pumped fiercely into him again. And again. Each time she slammed her fat cock into him another burst of jizz would squirt into the beaker, as if she was milking him of cum. Soon he was arching back to meet her, their big balls slapping together with each thrust, each motion pushing his cock into Amilia's hand. The pace increased until an almost constant stream of cum was flowing into the jar. Both of their faces were tight with lust and Jerome was gasping, his huge balls high and tight as they knocked into Amilia's small hand which didn't come even close to encircling his painfully swollen cock. "Now, Jerome!" The mistress cried, "fill up that beaker while I fill your ass with my cum! Make me proud!" She cried and slammed into him harder and faster than before. Jerome gave a strangled yell and ropes of hot jizz spilled into the beaker, almost splashing over the sides. The mistress gave a cry of her own as she spilled into him but kept stroking as stream after stream of cum poured into the beaker, filling it rapidly. Jerome clung to the metal rail, head hanging, shuddering with each load that left him. Slowly the pulses tapered off until each pump by the mistress's cock produced nothing more than a couple drops of jizz and a whimper from Jerome. "There we go, darling. Magnificent. That looks like almost 700 millilitres from here," the mistress leaned back and let her softening cock ease from his ass with a small wet plop. "Amilia, go set that in the specimen fridge and then clean me up with that lovely mouth of yours. Jerome, put your plug back in... I don't want you leaking all over. You can clean up after we've got my pet all settled in the milking chamber." She turned towards me and twined her fingers in Amilia's hair as the servant knelt down to lave her mistress's cock. "Now, my pet... What's this?! You've made quite the mess!" I hadn't noticed, but my nipples, high and tight from lust as I watched the scene before me, had been steadily dribbling blue tinged milk down my chest. I blushed. "I'm sorry mistress," I murmured. She jerked Amilia's head back from where it had engulfed her cock and strode towards me, her kimono falling into place. She swiped a finger through some of the liquid dripping from a breast and sucked it into her mouth. I gasped at that small sensation and another few drops dripped from that nipple. "Hmmm." She contemplated, "it could just be your milk production is already so high that you're overflowing and will need more frequent milking...but I think it might be one if those unknown factors I mentioned... You might leak when you're aroused, my dear. Well, time will tell. Jerome, Amilia, clean her up, the full works. Then fit her with a size 2 anal monitor - she's far too tight. We'll need to train her up to a 6 so I can fuck her comfortably... Or maybe a five... Wouldn't want you too comfortable, hmm? Put her in her milkmaid gear and then bring her to the milking parlor. No other attachments in her harness though until we get her first reading. Oh, and cap her nipples... We can't have her leaking all over the place." With that the mistress swept out of the room, muttering about volumes and serums. "Ugh! I hate it when she makes me clean her up after anal!" Muttered Amilia as she turned towards the cabinets. "You think she doesn't know that? That's why she makes you do it, Ames." Jerome said as he moved towards a stall, moving a bit unsteadily, and started filling a basin. I stood mute for a second as Amilia moved towards me. After a second I blurted "are we allowed to speak?" "You aren't, cow," she gave me a rough shove towards a stall. "We're servants. We came willingly into her service, not bargaining for some silly fetish enhancement. You are just livestock." She sniffed at me and fingered her jeweled collar. "Oh get over yourself Ames. You're just jealous you didn't think of it and now it's too late. The mistress won't give you any enhancements until you've stopped being an uppity snob. No one likes a bratty sub." Jerome said as he bent me over a bar in the stall. He held me there at the neck and inserted a thin lubed nozzle into my ass with his other hand. "Hmph. I wouldn't want any anyways. I've no desire to be a lab rat or a milch cow." Amilia took another nozzle and started washing my hair. "That's too bad. Did you see how much jizz I made today? And it felt incredible! Hold still now kitten, we're going to fill you up nice and slow. Don't be embarrassed, everyone goes through this. God you have magnificent tits. And they're leaking too... Does that warm water feel good filling you up? Your tits are already bigger than Bunny's were the day after she got her enhancement, and now she's got the biggest tits in the complex. I'm betting yours will beat hers. How I'd love to fuck them, slick with all that milk from your arousal and all the precum I make..." Jerome kept up his chatter as he filled me uncomfortably full. Amilia finished with my hair as Jerome turned off his nozzle. "There you go. Now clench up tight while I remove the wand and then off you go to the water closet over there. We'll at least give you that much privacy." I did as he instructed, and came out several minutes later. Amilia and Jerome continued chatting and verbally sparring as they finished soaping, rinsing, drying, lotioning and lubing me. Once that was done they worked another plug into my ass, larger than the one the day before, and slipped me into a leather harness. The harness was comprised of various straps around my thighs, hips, waist and shoulders along with metal rings. My breasts were lifted by wide shallow cups as if being served on a tray and a few decorative ruffles actually managed to suggest "maid". A second harness was fitted over my head and a bit slipped between my lips. Finally a couple of caps were strapped in place over my nipples to catch any leaking milk and I was guided out of the room to my first milking. Enhancement: Experiment Ch. 03 "An hour!! And still producing steadily! Unheard of." My mistress, wearing again a white lab coat, strode into the milking parlor. It was a pleasant room, done in blue and white, but still had a sterile feel to it with glass shelves and steel instruments. Proper commercial stables had anywhere from 3 to 10 stalls in a row where milk maids were brought in twice a day for up to thirty minutes of milking. Stables often had different themes to draw clientele to watch or participate in the milking. My mistress, being in the R&D side of the business, never had more than 10 test subjects at a time. This meant she only needed one specially calibrated research stall- a contraption with the same raised box-like frame that had been used for my enhancement procedure. Instead of straps, though, I was hooked in by my harness. It provided the necessary suspension points so that I was comfortably kneeling and bent over, my thighs spread wide, my large swollen breasts dangling heavily below me. Being exposed and helpless in that position had made me wet with desire almost immediately. Once the catching cups over my nipples were removed -almost overflowing with milk just from the short walk from the bathroom to the milking stall- and replaced with nipple pumps, I was practically humping air with horniness, my breasts aching with the delicious pulling sensation as milk was steadily drained from my nipples. That was 55 minutes ago. Forty-five minutes ago my nipples were starting to ache and my thighs were soaked with my desire. The mistress had muttered something about checking on another experiment and told the bratty sub Amilia to come get her once I ran dry. Thirty-five minutes ago the last of my lust had disappeared to be replaced with a steadily increasing pain centered in my nipples. Now I hung limp, bored and in pain, my pussy as dry as a desert, yet blue-white milk still streamed steadily from my swollen, distended nipples into flask after flask. If each flask was half a liter, then I'd managed at least 4 liters over all... A little over a gallon. "Well, this won't do!" My mistress had reappeared. "As much at I'd love to see how long you could go before running dry, I've no desire to ruin your sensitivity. We'll build up your tolerance first. Amilia, shut it off, clean up her nipples and put some healing salve on them." I shuddered in relief as the pumps stopped torturing my nipples. "Don't bother unhooking her. The salve should do it's work in about five minutes. Her milk rate is high for her first milking, but not unusually so. She deserves a few good orgasms, and if I want to keep on schedule, I'll need to see how that affects her production rate. An hour! No one goes longer than 20 minutes! I was expecting 15 minutes at most! This throws off my entire day, but I can't say I'm displeased. An unprecedented effect." The mistress came around to my head and stroked my shorn scalp as she directed Amilia. The salve felt amazing. It cooled my tender tit flesh and almost immediately erased the fiery burn of my unnaturally elongated nipples. "Now, hand me her gag monitor. I'll replace her bit with it since for science sake I can't fuck her mouth myself... and she responds so well to having a cock gagging her. You remove her anal monitor and insert the double phalloactuator with the clitoral gimbalator attachment." As the mistress gagged me I could see Amilia from the corner of my eye as she picked up two flat objects from a glass shelf and moved behind me. I heard and felt her unhooking some straps between my legs and then she inserted something soft and smooth that curved from my pelvic bone and up between my ass cheeks. I could feel something cushioning my clit and two small bumps protruding slightly into my vagina and anus. Straps were refastened. I squirmed slightly, puzzled, as the objects in my crotch were less intrusive than some panties I'd owned. The mistress opened her hand screen and started working at it. "I just need to input your personal pleasure parameters and then we'll set you with the standard program. Reattach the cups, Amilia, but set them to sensor start so they won't pump until she starts leaking. Don't worry my pet, we won't go longer than 15 minutes this time. There were go, all ready. Let's begin!" The mistress made a final motion with her hand and snapped her screen off. A split second later the items in my crotch started warming and softening. They started buzzing slightly and the one at my clit started a slow, languorous circling around my nub. Desire was slow coming back to me. I felt a bulging at the opening to my vagina, as if a thick cock head rested at my entrance. I squirmed slightly and it moved in just a hair further and then retreated. The circling at my clit, like a tongue, was drawing closer and closer to that small button. I squirmed a little more and then suddenly the pumps around my nipples switched on. The salve had mostly healed them- they were only slightly sore, and I moaned with the newly pleasurable sensation. Suddenly the tongue thing at my mound drew over my clit and I was firmly back in lust's grip. It started working tirelessly over and around my clit in a steady rhythm. The bulge at my entrance also started a rhythm, pushing slowly in and out, each time going in a smidge further, thickening a bit more. It was like a slow and steady tease, drawing me up and back down. The last bulge at my anus finally made its move, a tiny tendril pushing into me slowly, circling, and then retreating. Each time it grew a tiny bit wider. All the parts were slightly out of rhythm, though- I was getting pushed higher towards orgasm, but never over. The shaft in my pussy would penetrate me, but not at the same time that the tongue would swipe my clit. The anal probe would thicken and pulse, but then wither as the shaft entered me. It was maddening. It went in for at least five minutes, everything moving incrementally faster but never syncing up. The shafts were penetrating me deeply and were satisfyingly thick but my bucking hips did nothing to change the angle or increase the speed so that I could orgasm. I could hear the pumps ramping up steadily as my milk flow increased, tugging at my nipples harder. And then everything aligned. The shaft in my pussy plunged in as deep as it could and pulsed as it pounded me in sync with the probe that filled my ass and the tongue that rode directly on my clit with waving vibrations. I screamed around my gag and finally flew over the peak. My cunt sucked at the shaft like a cock, wanting it to fill me, and it obliged, growing even thicker and pulsing as it knocked into my womb. The probe in my ass responded the same, stretching my ass until it burned. Both plunged deeper into me as if trying to borrow inside of me, and the tongue on my clit vibrated with an almost audible whine. Another orgasm, but instead of flying, this time I plunged as the waves washed over me. The shafts in me felt huge, pounding me without mercy. I wasn't given any relief or rest. My orgasms were almost continuous, and I drifted in a haze of pleasure that verged on pain. Dimly I could hear the mistress murmuring as she took notes and gave instructions to Amilia. Finally the sequence started ramping down. I whimpered in relief as the dildos shrunk and the buzzing and licking at my swollen clit ceased. The mistress moved to my head and started unstrapping my mouth gag. She spoke as she worked. "Hmmm the salve seemed to do an excellent job... Your pain levels are still quite low. I admit, for partially selfish reasons, I think we'll perform one last experiment... Amilia, attach the liter collection beakers, and turn the pumps to automatic. Then you may eat my ass. Watching kitten here has made me quite hard... and it's been over 2 hours since I've gotten relief. If ingesting my semen can produce satisfactory results, we can go ahead and start the next round of experiments tomorrow. Amilia, stop being such a prig and use that tongue of yours girl! Now, my pet, open wide." The mistress unbuttoned her lab coat and brought out her already turgid cock. Behind the mistress's braced legs I could see Amilia kneeling as she did her duty. I wet my lips and licked the purple head before sucking it into my mouth. As before, she tasted delicious, and I struggled to take her girth and suck her in as deep as I could. I rolled my eyes up to look at her - she was pinching the nipple of one large breast with one hand, and with the other on the back of my shorn head she was guiding my mouth. Her face was relaxed and ecstatic as she fucked my throat. I brought my eyes back down and sucked harder, swallowing as much of her cock as possible, pleased to give her such pleasure. She gave a low moan as my cock worship paid off and she started fucking my mouth with vigor. My tongue and throat worked furiously at her thick length, flicking the head to taste any precum that collected there. I worked between breaths to suck sudden as much of it as I could. "That's it, kitten, swallow me down. Such a good pet. I'm going to cum now, swallow it all, every last drop!" She did, and I did. As I eagerly swallowed the last drops I heard and felt the pumps work harder on my heavily swollen breasts. Despite my recent prolonged orgasm, could feel wetness dripping down my thighs again and I longed to be fucked. The mistress let her cock soften in my mouth as the pumps worked at me. She pulled out, her semi-hard cock glistening with my saliva against her thigh. The mistress petted me with one hand as she did up her coat buttons with the other. "Mmm, lovely. You may stop Amilia. Monitor her output and stop the pumps once she returns to her baseline rate, then escort her to her room. Now kitten, I'll be leaving you in the harness with the climax aids in place. You're to wear them constantly. Don't worry, everything is waterproof. You have leave to use them whenever you need, but you're required to hook the pumps to your breasts when you do. Your room has been outfitted with a set of them by your bed. In fact, the harness won't activate until you've turned on the pumps. You have my permission to orgasm however much you like... You'll know when I want you to stop. I'll see you midday tomorrow for your next experiment." With a kiss to my forehead the mistress left the room, leaving me alone with Amilia. The veneer of servility dropped completely from Amilia. "Are you proud of yourself, you cow? 'An unprecedented effect'," Amilia mocked. "You could have been anyone. The mistress should have selected me. 2 years in her service and she hasn't given me a single enhancement. Well, at least I'm not an experiment. You're going to end up a milch-cow, milked day and night and fed only sperm the rest of your days. You like those big tits now, but just wait till they sag to your waist and your nipples are the size of saucers." I glared at her. My gag had been replaced or I would have given her a piece of my mind. I'd known what I was getting into. I was smart and educated in the sciences, but with other species being smarter there were limited job opportunities for humans in science these days. At least this way I was being a part of science and gaining a lucrative career option as a milkmaid. Plus I'd always been fascinated with milkmaids. The fact that my attributes were outstripping those of the average milkmaid made me secretly very excited. Maybe the mistress would even have a job for me once my contract was up and I could be research assistant and milkmaid both. Amilia ignored me in fuming silence the rest of the half hour my milking took. She marched me back to my room, impatiently removing my head harness, and then left without a word. I sighed in relief, and then eagerly looked for the pump station, still horny from earlier... Enhancement: Experiment Ch. 04 I was glad to finally be back in my room. It wasn't much past midday but I was exhausted. All I'd done was sleep and eat the day after my enhancement as my body underwent numerous transformations. The first round of experiments had started immediately after I'd woken today. It was my third day here, but I hadn't had a moment to look at my new traits or explore my changing body. Now I stood in front of the projection wall and studied myself. I wasn't used to seeing myself bald, and I briefly mourned the temporary loss of my aquamarine hair. My boobs were much larger. Huge, even. If the mistress's had been cantaloupe sized, mine were already the size of very small watermelons. My waist actually seemed smaller, but I wasn't entirely sure. I panned around to look at myself from the rear. Definitely smaller unless my ass had grown as well. I continued panning with swipes in the air and then I frowned and zoomed in the camera. I looked down at my breasts to confirm. There were stretch marks from the rapid growth my breasts had undergone. I retrieved some skin cream from the bathroom and started massaging it into my flesh. The stretch marks disappeared, but touching my huge breasts felt amazing, like a dream come true. I squeezed and fondled them, enjoying the sensations as they overflowed my small hands. I started dribbling milk again. I pulled hard at one long nipple and then the other, watching as they made tiny spurts with each tug. Amazingly, despite orgasming to near exhaustion a half hour before, I was getting horny again. I had always had a high libido, but nothing like this. I moved to the bed to explore the milking setup depending from the headboard. I pulled out the suction cups and placed them over my nipples. As I did a mobile screen appeared. With it I could control not only the suction, but the dildos and clit vibe imbedded in the unobtrusive machinery strapped between my legs as well. I smiled and laid back on the bed, happy to spend some time controlling my own climaxes. ______ By noon the next day I was leaking from pussy and nipples in uncontrollable lust. I'd spent several intermittent hours last night milking myself and bringing myself to climax. It was almost as if the more I came, the hornier I got. When I woke late this morning my bed was soaked from lustful wet dreams and I was looking forward to several orgasms until my noon appointment. Unfortunately, the pumps had been deactivated. The device between my legs which had brought me so many orgasms just a few hours before now acted as a chastity belt, preventing me from finding relief in any other way. Playing with my boobs only brought more frustration. I distracted myself by watching the news, rebalancing my retirement portfolios, and eating a sumptuous brunch of fruit crepes drizzled in chocolate. That was one good thing about my stay- while I wasn't earning any credits, I also wasn't paying for rent or meals. However, it also meant no outside contact with friends or family, either. My mother, a famous concubine to Empress Ilkatravia the third, was now retired on the human pleasure colony on Florida ( a slight irony, since she'd been born on one of the Floridian islands of Earth back before they had finally succumbed to the sea), so she wouldn't be worried if she didn't hear from me for several months. Interstellar communication was still entirely dependent on ships. Other species had instantaneous interstellar communication, but they guarded their technologies ferociously, especially from violence-prone humans. My best friend knew of my contract, so he wouldn't be expecting to hear from me for months as well although I was dying to send him some holos of my new figure. I toyed with the room computer and considered trying a hack or two. But then the noon chime if programmed sounded and I jumped up from my couch eagerly as my door slid open. Jerome stood there, naked except for his collar. He looked me over appreciatively, taking in my wet thighs and dripping nipples, and sniffed the air. I blushed, knowing my entire room reeked of my lusts. "You're all good and worked up, aren't you kitten? Don't worry, you'll be taken care of. Let's get you to the milk lab and strapped in for the next set of experiments." He took his time clipping my arms behind my back and putting on my head harness with its bit. His hands brushed my sensitive breasts and nipples several times, and he guided me down the hall while fondling the full globes of my ass. "Mmm, your breasts are definitely larger today. And all that milk leaking out... I bet it's delicious," he murmured in my ear. I much preferred him warm appreciative presence to Amilia's cold hateful one, but his attentions were only spiking my prolonged arousal. In the milk lab, Jerome clipped me into the milking stall, attached the pumps, removed the device between my legs and worked a large anal monitor into my ass. Again, he didn't keep his hands from wandering. Lastly, he removed the bit from my mouth and shrugged into a lab coat right as the mistress arrived. She brought guests with her. "Here we are, gentlemen. Thank you for volunteering for this experiment. You've all been briefed on what's expected of you, but I'd like to reiterate that you can fuck her vagina or mouth, but you absolutely must ejaculate in her mouth. You will only be compensated for that. I would also remind you that the more times you cum, the more you get paid. You'll have fifteen minutes. Starting... Now." She gave an invisible signal and immediately a naked man moved around to where I could see him, his hand pumping his average sized cock. He quickly stuffed it into my mouth and grunted as streams of jizz pumped down my throat. I swallowed reflexively and made a muffled noise as I felt a large cock being stuffed into my pussy. "Good girl, kitten. I didn't have to tell you to swallow. Lovely. Keep swallowing all that semen, my dear." The mistress monitored me from beside Jerome, making notes and occasionally fondling Jerome. The man in front of me removed his spent cock and was quickly replaced by another. This one was long and skinny and slid easily down my throat. He fucked my mouth vigorously, grabbing my head, for half a minute before unloading his jizz. The cock at my pussy was pounding at me hard as well, much to my delight, his balls slapping my clit. I wasn't even close to cumming though when he pulled out and replaced the thin cock in my mouth with his own fat one, jerking himself to finish in my mouth. An average sized cock started fucking my pussy now. Like a game of round robin, one cock was rapidly replaced by another at each end. I swallowed load after load. I could see from the corner of my eye men lining up, all jerking themselves off, and sometimes each other. One man was willingly fellating another as he jerked himself close to cumming. The mistress nodded at this and sent Jerome to kneel and suck some men closer to completion as well. Amilia arrived and the mistress gave her the same task. Someone was always fucking me, but never for long enough and in the same rhythm to let me orgasm. I would have screamed in frustration if I hadn't been too busy swallowing semen. With Jerome and Amilia acting as fluffers orgasms were getting faster. I was distracted from my own possible climax by my struggle to swallow it all. They even started stuffing their bursting cocks in my mouth two at a time, making my cheeks bulge and my jaw ache. I managed, though. I didn't usually like the taste but, perhaps because of my altered genetics, they all tasted delicious- like various exotics fruits. I lapped it up and swallowed it down eagerly. I think I counted around nine different men, and each managed to cum at least twice, some three or four times., I lost track but I think I ended up swallowing at least 30 loads of semen. I was getting incredibly full, but still I sucked it down. Finally a low gong sounded. "Time! Gentlemen, that was quite marvelously done. Very efficient. Amilia here will show you back to the locker room and if you're still needing relief you may use her in any capacity you'd like." I could see the men grin at each other and eye Amilia lasciviously, despite their multiple orgasms. No doubt they'd been given performance enhancing drugs and would be ready to go for at least another hour. I hung in my harness and licked my swollen salty lips as they filed out. The pumps were sucking hard at my nipples, and I could feel juices running down my thighs. I was frustratingly horny, but apparently an orgasm for me was not in today's experimental protocol. I was milked for almost thirty minutes as the mistress made notes. A few minutes before the pumps started winding down Jerome started slowly sucking her cock while stroking his own. "Ah, good. Right on time. I think I'm starting to sense a pattern. We'll need to repeat the experiments several times to be sure, but so far everything is as I expected. One more experiment to go, today. Jerome, my darling, I've analyzed your semen and I'm most eager to see it's effects on our pretty pet. If you would be so kind as to fuck her mouth? And in the meantime, I will take advantage of your tight ass once more." Jerome suppressed a pleased grin as he moved to obey. His cock was huge and hard as he positioned the massive head between my swollen lips. His cock was bigger than even the mistress's and I trembled and salivated all at once imagining taking it for my own. He was already leaking precum and if the other men had tasted like fruit, I could only describe Jerome's cum as tasting like the most decadent creamy dark fudge. I moaned and lapped at his slit as he wedged his head into my mouth. He was so huge I had to practically unhinge my jaw. I heard him grunt and felt his cock push further into my mouth and knew the mistress had started fucking his ass. So the mistress fucked him and he fucked my mouth, each stroke making my jaw ache but rewarding me with a spurt of his rich semen. I strove to suck at him and take more into my mouth, my tongue licking at him furiously, starving for more of his delicious taste. My eyes watered with the pain of my stretched jaw as each stroke took him deeper into my mouth, but still I sucked on. Finally I heard them both panting rapidly and the mistress whispered, "Now Jerome." He was well trained. He gave a strangled cry, grabbing my head in both hands as he stuffed himself down my mouth and unloaded stream after stream of hot delicious jizz into my throat. I swallowed. And swallowed. It seemed like it never ended. I could feel my stomach swelling with load after load and remembered he'd cum over half a liter yesterday. I tried to keep up but I could feel it leaking from my mouth and dripping from my chin. Despite my best efforts, his cock popped out of my mouth and I coughed and gasped as the last few ropes of his cum ended up dripping down my face. I still licked at what I could, fearful of disappointing my mistress. I was aware that my breasts had swollen and were aching even more than usual. The pumps sucking at my nipples were working furiously, draining me as fast as they could. I whimpered at the spikes of pleasure they were sending to my sodden, empty cunt. "Oh yes, very good! This rate is quite unexpected. Jerome, do some clean up while we wait to see how long she sustains this output." Jerome knelt to clean the mistress's cock with his tongue. "Kitten, I'm very pleased you managed to swallow as much as you did. I'll have Jerome reattach the phalli device before he takes you to your room. I'll give you back control and you can orgasm to your heart's content tonight and tomorrow. I'll be busy crunching numbers and it's a rest day anyways, so feel free to explore the compound. Jerome can introduce you to the other test subjects and servants if they're around. Again, though, you'll be wearing your harness and must be attached to the pumps in order to activate the phalli. Understood?" I nodded as much as the head harness would allow. "Excellent. Jerome, you know what you do. Tata, darlings." Jerome watched as she left and then darted forward to kiss me, hard and fast. I gasped as he moved away. "Jerome! You'll get in trouble!" He grinned at me wickedly. "You're worth the trouble. Your mouth was amazing. Way better than Ames ever was at sucking cock." He retrieved a wet cloth at wiped at my jizz smeared face. "Now no speaking or you'll be the one in trouble. I bet you're looking forward to activating that phalli device aren't you? I'd fuck you right now if I could get hard. You drained me dry, kitten! But your ass looks so good, those big round globes and spread thighs. And your pussy looks so needy right now, all wet and bright pink. Even your clit it hard and swollen. I bet you're going to have 5 orgasms before you pass out tonight. You know you have monitors in your room? I'm going to spend my night watching you fuck yourself into oblivion. I'm allowed to make myself cum on rest days, so as soon as midnight hits I'm going to soak my sheets with jizz as I watch you, milk spurting from those big tits of yours, imagining those big dildos in your ass and pussy fucking you hard and deep. So give me a good show, won't you kitten?" He caressed my head and met my gaze, smiling entreatingly. I just gave him a sly smirk and said nothing. Enhancement: Experiment Ch. 05 Author's note: Sorry for the short chapter... I need a bridge for the next story arc. Sylver ***** I was gulping down Jerome's thick delicious semen, my mouth stretched around his massive head as he unloaded his half gallon of sperm into my stomach, when I heard the mistress walk in. For a week, this was our routine, except the mistress didn't let him fuck my mouth much anymore, just jerk himself close to completion before emptying himself in my mouth. There were usually some variations, but if it wasn't Jerome's jizz, it was the jizz of a dozen strange men instead. The mistress needed replications for her research. I was still trying to decide if this was something I could put up with for the rest of my career. It was pleasurable but very routine. I wondered if I ended up as a milch-cow -as Amilia had threatened -if my employers would let me listen to audio books. The mistress was speaking as she entered. "Here's my latest and most successful experiment. She's quite unlike the standard milk maid. Not only can she be milked continuously at an above average rate, but when I give her a regular dose of semen her rate increases by half for thirty Earth minutes, and by another half when she's orgasming. Usually a quarter increase is the most you can hope for. But that's only the beginning! When I give her Jerome's semen her output triples! Watch, it's happening now." And it was. As I finished sucking the last few delicious drops from Jerome's cock I could feel my breasts swell achingly where they hung between the harness straps. I heard the pumps increase, sucking harder at my elongated nipples. At that moment the ever present device between my legs switched on. The dildos in both holes inflated rapidly and started fucking me in the pussy and ass while the mechanical mouth at my clit hummed rapidly. It didn't waste time any more. Its sole purpose was to bring me to climax as fast and often as possible. "Delightful! And how long does she produce at this triple rate?" This was from the guest who had entered with the mistress. It's voice was silky and deep. "Unfortunately, it still only lasts for about a half-hour. Jerome usually takes 3 hours to recover full sperm production, or I would try dosing her every thirty minutes to see how long she can sustain tripled output. I have started milking Jerome of sperm regularly though, and will soon have enough stored up to try that experiment. Amilia! She's about to cum, be ready to increase the pumps if her output increases. Ser Oresk, this is the third repetition of this experiment, to confirm that Jerome's sperm and her orgasm will increase her production rate by a factor of 4." The mistress was right, orgasm was creeping up on me. I'd been slightly distracted listening to the mistress's dialogue, but now the intense sucking at my swollen breasts and the rapid pounding of my pussy and ass overwhelmed me. I shuddered and bucked in my restrictive harness and screamed around the huge semi-hard cock in my mouth as waves of pleasure blew through me. The relentless dildos kept pounding me, lengthening the sweet pain of orgasm. My pussy and ass sucked them in as I came. Each wave sent milk gushing from my nipples into the ever hungry suction cups. After a minute or so my body could take no more and I hung limp and whimpering as the dildos kept working at me, urging me to my next orgasm. "Time! Lovely, it looks as if production increases during orgasm still, although not much past. I will have to read the literature to see if milkmaids can be trained to prolonged orgasm. Unless you perhaps have some insight Ser Oresk...?" 'Oresk' gave a sibilant laugh, making me think it was probably an Edemsa, one of the thin elegant red reptilian-like species of the Clothos system. "Indeed not, mistress Ahm, you know I'm in supply and demand not research and development. Tell me, have you tried symbiotic pregnancies yet? I hear Ploidians feed a very strong hormonal fluid to their captured symbionts while their eggs are gestating, and their reproductive cycles can go for days. My own species can use humans as our reproductive hosts, and I've heard rumors that our gestational hormones can have quite an effect on lactating humans...Perhaps you'd like to include me in your experiments? I'm sure I could even find an eager Ploidian with no trouble..." The thought of being a host for alien pupa filled me with horror but also sent a spike of lust through me that sent me into another brief orgasm. Dimly I heard the mistress give a throaty chuckle. "I would love to include you in my experiments, dear, but you know treaties forbid interaction between aliens and milkmaids because of the dangerous aphrodisiac properties of their milk to other species." "I hear the black market for such can be quite lucrative, though..." "Oh Ser, I'm sure it is, but in order to continue to receive funding and publishing rights, I have to stay firmly on the right side of the law. However, if you are nearing your reproductive time, I can offer Amilia here to attend you for the duration of your visit. Although she desperately desires enhancements, she is free of any such genetic tampering and thus legally allowed to be surrogate for your offspring." I could see Amilia from where I hung on the milking platform. Disgust and hatred soured her pretty face before being quickly suppressed. "Hmm, she is comely for a human. I believe I will take you up on your offer. I have been delaying my cycle for an uncomfortably long time." "Excellent. Shall we continue our tour? Amilia, you know the routine. After kitten is finished Jerome can escort her back to her room. You can clean up and then meet Ser Oresk in his rooms. This way good Ser..." I heard a door swish open and closed. Jerome was still languidly fucking my mouth with his semi-hard cock. "Well, Amilia, how do you feel about giving birth to a litter of snakes this time tomorrow?" I could hear the smirk in his voice. "Fuck off. I'm sick of how the mistress abuses me. An entire year of service and nothing to show for it. She lets a bunch of common men use me as a cum dumpster every time she brings them in for her milch cow experiments and now she wants me to fuck an alien and birth his slimy babies? I've had it!" "You volunteered for this, Ames. What were you expecting? You signed on as a sub but have yet to act as one. Of course the mistress sees that. Sometimes I wonder if the mistress isn't trying to get you to break your contract." "Well, I'm about to. But I'm not leaving empty handed." Amilia slammed home a drawer and stormed out. "Bah, she's full of it." Jerome looked down at me and smiled as he caressed my fuzzy blue scalp. Then he grabbed the back of my skull and thrust deep down my throat. "Mmm, you tempt me to disobey the Mistress's orders. I want to suck and fuck your enormous tits so bad" he thrust again and I gagged as his cock hardened and lengthened while he held me immobile against him, choking me with his length. He pulled out with a sigh and lightly slapped my cheeks with his wet dick. "I'd better go find Amilia and bring her back to her duties before we both do something we'll regret." He left and so I hung there alone, bound immobile and shuddering with intermittent climaxes as I waited for my handlers to return. Enhancement: Experiment Ch. 06 Final "Jerome! What are you doing in my room? " I'd been relaxing, catching up on interstellar news when Jerome walked in and closed the door behind him. He stood in front of the door, naked and huge, and stared at me. His eyes roved over me as I lay in the bed, my news reader doing nothing to hide my massive tits. His eyes fixed on them and his limp cock started swelling. "I can't take it anymore, kitten. Every day I watch you getting fucked and having those huge breasts milked and the most I ever get is to unload in your mouth. I'm tired of being jerked off into a beaker! I need you, kitten, I need to fuck your huge breasts and cum in your tight pussy." His face was tight with desire and determination as he made his declaration. "But, the mistress would never..." "I don't care!" He growled and pounced on me, pinning my arms to the bed and kissing me fiercely. I moaned at the forbidden contact. It was true. For the past two weeks I'd had near endless orgasms but no touch, no warmth. I melted into his mouth, kissing him back. He felt my acceptance, my eagerness and let go of my wrists, doing something so that my ever present harness melted away. His grasped my breasts and started kneading them fervently, his huge hands dwarfed by their fullness. I wrapped my arms around him, reveling in his smooth warm skin. He squeezed my tits delightfully hard and I moaned into his mouth. My nipples were leaking and his fingers were getting slippery as he played with them. He stopped kissing me to pull back and watch. He tugged at my nipples and milk squirted from them, coating his fingers. "Amazing," he whispered and then leaned over to suck one long nipple into his mouth. I gasped as I felt him suck hard, then bring up his hand to squeeze my breast while he sucked. His other hand tugged at my other nipple and each suck and tug and squeeze sent jolts of pleasure to my pussy. I moaned and brought my hands down to find his cock. It was not difficult- he was huge and hard against my thigh, slick with precum. I spread it around with my hands and then started sliding my hands up and down his cock. Even with both hands I could barely encircle his girth. He groaned against my breast as I toyed with him, and then switched nipples, eliciting another gasp from me. After he'd had his fill of that one he squeezed my huge tits together and sucked both nipples at once into his mouth. "Aah! Jerome that feels amazing!! Harder! Suck harder!" He did, gulping down the milk that flowed from my swollen breasts, and each suck sent a spike like a mini orgasm to my soaking cunt. His cock was so huge, and he was humping my hands as he sucked. I wanted him in me, splitting me open, so badly. He finally gasped and pulled away. "Too much! I want to fuck your magnificent tits first." He moved up to kneel over my chest and cradled his massive cock between my melon-sized mammaries. His cock head emerged from the top of my tits and nudged me in the mouth. I drew him in and started sucking up his delicious precum a he wrapped his cock in my milk-slicked breasts. "Oh gods! You feel amazing!" He cried as he fucked them. With each thrust my nipples squirted like mini fountains, and his cock responded with an extra spurt of jizz in my mouth. The aphrodisiac in my milk was affecting him because he was producing more precum than usual. In turn, the hormones in his jizz were affecting me. I could almost see my tits get larger and milk squirted out with force, more with each thrust. We were soon covered in jizz and milk and soaking the bed in both. "Jerome! Jerome!" I cried, trying to break through the animalistic fog that had crept over him, "please! I need you to fuck me! Please!" He didn't seem to hear and kept thrusting manically at my tits. Finally the slipperiness undid him and his cock burst free from between them. I seized my chance- my own animal-like fog was demanding I force his gigantic cock into my pussy and suck it dry. I flipped him onto his back and kneeled over him. My huge breasts hung over his face. My pussy was drenched with my desire and his cock with slick with jizz and milk but still, it took long agonizing seconds to force his steel-hard thickness into my tight cunt. As I worked myself onto him he took both long nipples into his mouth and sucked hard, pulling at my tender breasts and gulping down more aphrodisiac milk. He was so wide, wider than my personal fucking device could even go. It hurt but I was determined, impaling myself millimeter by millimeter. I took him as far as I could and hung panting, my pussy throbbing with pain and pleasure as it stretched around him and he suckled at my tits. I whimpered as he moved his hands to my hips and started lifting me up and down with slow thrusts. My pussy loosened up a fraction and accepted a little more of his thick long length. He started fucking me faster. I screamed at being stretched so wide, yet at how unbelievably good it felt. Faster, he fucked me and I could feel his cock swell even more and knew he was about to cum. Instead, he lifted me until just his tip was stretching my entrance and held me there. I whimpered and wiggled in his hands, close to my own orgasm, needing to suck his cock into the depths of me and drain his sperm. Just when I couldn't take any more he slammed me down onto him. I screamed as he penetrated depths no one had ever been before. My nipples popped free of his mouth as he buried his face in my enormous tits and yelled, his hips jerking as he unloaded his massive load deep into my womb. I yelled too, as pain and pleasure washed over me and my pussy convulsed around his exploding cock, pulse after pulse of hot jizz filling me up. My pussy sucked it up greedily, deep into my rapidly filling womb. I collapsed on top of him, my breasts smothering him. He rolled us to our sides and started sucking at my nipples again, languidly. We rested, but his cock refused to soften, still painfully hard and reaching far into my depths. It made a tight seal so not a drop of his massive load had leaked out. It made my womb feel swollen. "Fuck... Kitten," his voice was tight, "I need to cum again, I'm so hard... This has never happened before!" He latched back onto my nipples, sucking and biting them painfully as he drew out more milk. Having swallowed his jizz, my breasts released even more milk, yet continued to swell painfully. I think the direct penetration of his semenal hormones to my womb were having an even larger effect on my milk production than usual. He started pumping into me again, short quick thrusts, trying to bury himself deeper and deeper into me. I felt painfully full, both my tits and my cunt. "Jerome, please... My breasts, my womb... I feel like I'm going to burst! Don't cum in me again!" I pushed at his shoulders but he just growled and sucked harder on my nipples. He seemed mindless, thrusting harder and deeper, sucking at my nipples until I wondered how he had managed to drink all the milk I must be producing. His thrusts were faster now and his cock swelled painfully large. He grabbed me and held me to him, letting out a strangled groan as he unloaded another massive load deep into me. I cried out with the pain and pleasure of feeling so full, my abdomen visibly swelling with each throb of his cock. With one last thrust and a whimper, I felt Jerome's whole body go slack. "Jerome?" I shook him. He had fainted, milk dribbling from his slack mouth, his eyes rolled back in his head. I knew now why our encounters had been so carefully controlled. Our enhancements were each so strong and complementary that they could create a feedback loop until we fucked each other into permanent injury. Already my breasts ached and leaked uncontrollably as the direct input of two massive doses of his enhanced sperm increased my milk production. I groaned and worked myself away from him, trying to unwedge his cock from inside me. Even unconscious he was thrusting his hips and loosely grabbing onto me. I finally extricated myself and was rewarded by a flood of semen gushing out of my pussy. It soaked what few dry spots were left on my bed. Jerome whimpered as his cock reluctantly popped out of me and his hand went to his cock, pumping it. I licked my lips. Even now, my breasts swollen and leaking painfully and my pussy throbbing and sore, desire to suck his cock and swallow more of his delicious semen washed over me. Instead, I waddled into the bathroom and locked myself in. I turned on the shower and milked my own aching breasts in relief as I stood under the cool water. I hoped Jerome would be OK. The aphrodisiac properties of enhanced milk only had a weak effect on humans, but Jerome had drunk a lot, and there was no telling if his own enhancements would increase his susceptibility. As I finished milking my tits I yawned, suddenly overwhelmed with fatigue. I dried quickly and then stumbled out of the shower and bathroom, darkness encroaching the edges of my vision. The sight in my bedroom startled be briefly back into alertness. Amilia, fully clothed and standing in front of two hulking Temunitu, was in my room waiting for me. "Well, kitten. Did you enjoy that little love fest? As soon as I saw Jerome succumb to you, I knew that was the last straw for me. You and Jerome and mistress will all pay for treating me like you do. Take her!" "What..?" I gasped but the huge green reptilian-like aliens were already on me, their massive three-fingered hands muffling my cries and binding my arms and legs. Jerome continued weakly fucking his own hand, dead to the world. I saw two more large Temunitu grab him before I was bundled into invisi-cloth and carried away...
