"Wh-What are you going to do with that?" I panicked, the scientist coming closer and closer to me with his rolling table of shots and creams. I was laying naked against a cold steel table, my bare skin getting goosebumps from the contact of the it, causing my nipples to perk up. Squirming, I tried to free or loosen the shackles around my wrists and ankles, but the restraints were too tight against my skin. After a moment of doing so, I realized how that was a pretty dumb thing to do considering it was literally metal.

"Mistress said she wants to find a way to use the new barn out back, so I'm giving you the modifications you need in order for her to use it." He smirks down at me, the gleam in his eyes making me inwardly shudder from fear. Equipping one of the shots from the tray that had a green tint to it he poked the needle through my clit, injecting the serum. I yelled profanities and balled my hands up tightly into fists from the pain, tears were starting to form in my eyes.

Once every ounce of the liquid was emptied out into my clit, I could feel a weird pressure all over it. As if it were a burning pleasure. Blinking the tears away I gained the courage to look down and see what was going on. I gasp in shock as tears start rolling down my cheeks again, to my shock I was starting to grow a cock and balls. "What did you do to me?" I leaned my head back against the steel, my eyes pouring out tears.

"Don't worry about it, I just gave you an add on." He grasps his rolling table, pulling it closer to the upper half of my body. Throwing out the used syringe he grabs another one, aligning it with the tip of my nipple. He pokes through the delicate bud, injecting the pink liquid into it before doing the same with your other nipple. My breasts started to expand, growing bigger as well as my nipples. My rosy nipples soon became big and long enough for someone to hold completely in their hand. My voluminous breasts started spilling over the sides of my body whilst my nipples dangled a bit to the side.

The Scientist grasped onto my nipples and started to tug them around, making my body become hot and my nipples erected. The tips of my nipples started opening up a bit. My new cock was pulsating against my abdomen and started to leak precum. Moans leaked out of my mouth as he played with me, "St-Stop- Do-Don't touch me-" I could barely say what I needed because of the pleasure being so great.

He scoffed at me, "Don't think I'm doing this for fun, I'm doing this to make sure everything has gone correctly. I have no intentions on doing this for your pleasure." I held back a whine and endured what he was doing until milk started to leak out of my breasts.

I watched as he let go and started to take notes on what was going on with my body. He then took off the binds that were on my wrists and ankles, allowing me to sit up. I didn't move, knowing that if i tried making a run for it I would get in more trouble than before.

"One moment." He turned and left the area, coming back a few minutes later with a collar, clipping it around my neck before he connected the leash to it. He tugged on it to check how strong it was. "Get up, we're I'm taking you to the new placement."

As we walked through the mansion I was covering up my cock with both of my hands, knowing my breasts would be exposed no matter what. With each step my breasts bounced and my nipples flopped around, too big to handle the pressures of walking. We walked by some of the staff and they eyed me down, looking over my body and actually getting aroused by it.

The scientist made his way to the back door, opening it and giving me a view of the barn he had mentioned before. It was rather big but also looked very unused. He tugged on my leash and pulled me in.

The setup on the inside was like nothing I had seen before. When you first opened the wooden doors you're greeted by stalls that were all completely empty, clearly hasn't been used yet. Milk machines were lined up at each station just begging to be broken in.

He placed me in the first stall, tying the leash against one of the poles before going to one of the walls that was decorated in machines and sex toys just waiting to be used on whom ever the victim was. This time it just so happened to be me. He had gotten a chastity belt with a hole through it so my cock and balls would be out and ready for punishment. Then the fairly thick vibrator with notches and edges all around it.

The scientist stepped into the stall with me, I was clearly shaking as he pulled me closer to him. He forced me to spread my legs as he slid the bumpy vibrator in. The only lubricant he had used was my own juices that spilled from me walking to the barn.

"Tch, you're nothing but a masochistic exhibitionist." He shoved the vibrator inside and then the chastity belt followed followed along soon after. My new cock stood eight inches proudly off my body. It was twitching with every movement I had made because of what was inside of me. My balls were becoming heavy from how sensitive I was with my new cock. The vibrator was gliding and grinding against my g-spot giving me chills.

I was enjoying myself so much that I didn't even realize it when I was turned and bent over a medieval post that closed over my hands and neck, my breasts and erect nipples just dangling over the concrete floor. My nipples were barely not touching the floor, milk dribbling out of them already.

The milk machine was soon hooked up to my enormous nipples, sucking and pulling onto them at the lowest speed, building its way up. I could no longer control my sounds of pleasure, moans started spilling passed my lips with no remorse. My cock was leaking out precum and throbbing, needing to be touched. I whimpered and shifted my hips a bit.

"Ca-Can you please pl-play with my cock?" I said hopefully as I chewed on my lip while my body was undergoing such pleasure.

I couldn't see his facial expression but I sure as hell felt the slap against my ass from asking such a question. The handprint had a burning sensation even after it left my skin.

"Do I need to repeat myself? You aren't getting a climax from me. I'm simply here to make the modifications to your body as time progresses." He then took the collar that was around my neck and wrapped it suffocatingly tight around the base of my cock, preventing me from having any kind of release. "Your Mistress will be in here later, don't make too much noise in here." He turned the vibrator that was inside of me, onto the highest setting, letting it hit my sweet spots with no stopping.

On that note, he left me in the barn, moaning and squirming as the machines toyed with my body. The constant tugging and sucking on my nipples gave me shivers that ran through my entire body bringing me closer and closer to my release. My pussy juices started leaking passed the chastity belt and down my inner thighs. My body was growing hot and I felt something building up inside of me while my balls were becoming heftier than before. Right when I felt like my release was coming everything shut off, leaving my body quivering and my knees weak.

After a few hours of being with the machine I learned a little bit about it. It shuts off after 30 minutes of constant milking, but as it shuts off it also clenches against my nipples, vibrating them for the same amount of time as if it needed to recharge. Each time it would stop to vibrate, the milk in my breasts would slowly build up and cause them to grow even bigger than before, my nipples getting tighter in it while it vibrated. I started to shift back and forth on my feet, the pleasure becoming unbearable. My cock felt like it was going to explode.

The vibrator seemed to be sensory because every time I felt like I was about to cum, it would turn off and wait about ten minutes before it turned back on. My cock was aching as my body was begging to have some form of release, there was hardly any precum that would ooze out for it.

Soon sun had fallen and my trainer wasn't here yet, making me believe that there really wasn't one after all and I was just standing there to suffer through orgasm denial the entire night. Just as I had lost hope for there actually being someone coming in and helping me release, the door was being opened.

I was unable to respond with anything but begging because of my need to cum. My cock was twitching and my juices were leaking down to the floor, forming a puddle beneath me. "Pl-Please make me cum, I want to c-cum!"

The only response I received was another slap on the ass, and a hard one at that. I yelped in pain and let out a small moan, liking the mix of pain and pleasure. Before I knew it the pleasure had all completely stopped and the milk machine turned onto the lowest setting, just barely getting the milk out of me.

"You aren't cumming anytime soon, haha." A feminine laugh had been heard from behind me. I wanted to turn and see who was talking but I couldn't because of my hands and neck being restrained. "Your cock was drooling even though the collar was so tight? Maybe I need to get you something tighter." Her hand was resting against my ass, feeling it up as she dipped down to my pussy, feeling how wet I was through the chastity belt. I could hear the keys rattling, a sign that she was about to unlock the chastity belt or better yet, my hands and neck.

Once she took off the chastity belt and slid the vibrator out from in between my folds causing a gasp to leave my lips, she put them off to the side as well as the milk machine suction cups. She then came to where my head and wrists were, letting me stand up straight and facing her.

"I am your trainer and my objective is to make you into the mansions cow. You will refer to me as Mistress." She eyed me down through her long eyelashes, watching me carefully. I believed her gaze was mesmerizing but perhaps that was just because of the fact I had been edged all day with no release. Her voice snapped me out of my trance.

"Time to see what today's progress has done."

Her soft hands felt up my breasts, as she inspected them, then moved to my elongated nipples. They were so big they drooped downwards, milk dribbling out. They were being tugged and pulled on, noticeably bigger than before. She then leaned down and latched onto one, suckling on it in her mouth. It hardly fit but she started bobbing her head as if she were giving it head. My knees were already weak so I placed a hand on the wood post next to me so I could stand.

Her tongue wrapped around it as she sucked on it, stuffing the entire thing into her mouth. She was moving her head up and down, taking me completely in. My milk was pouring out into her mouth while she sucked on it. After a minute or two she pulled away and did the same thing to the other nipple, nipping at it a few times. She started forcing her small mouth onto the entire length as she got it wet and hard, milk dribbling out of it and down her throat. She soon pulled away and left me panting heavily, my cock standing straight up, drooling precum as it was before she had came into the room to toy with me.

She reached into her bag that she had brought, "These will be on you during the next few nights to see how things go." She pulled her hands out and in them were two metal clasps that would be wrapped around my nipples.

Mistress grabbed some lube out of the bag and spread some in her hands, grasping onto my nipples and getting them slippery first before she put on the clasps. When she finally got around to putting on the clasps, they squeezed around the middle, causing the tips to just to get puffy and poke out. My nipples no longer drooped with them being on me, they stood straight out,my face turned a red shade from how it must have looked. She flicked both of the tips of my buds with her fingertips before crouching down to my cock, smirking because of how hard I was. I could feel her hot breath tickling my skin as she got close to it.

She grabbed onto my cock tightly, looking up at me, "This won't be cumming for a while so endure everything I give you and I might consider letting you cum." I winced from her grasp and whimpered from what she said, wanting to cum at that instant. I chewed my bottom lip and nodded my head, knowing that being obedient got me what I wanted faster but also aware that my patience was running thin. She grabbed the ring that was placed around my cock earlier and slid it on me, making sure it was tighter than before so not even precum could leak out. Soon she placed the dog collar back around my neck, with the leash connected to it.

"Mistress? Is it time for me to take over for you tonight?" A voice was heard from the door of the barn, coming from a taller girl who had short black hair with an edgy style to it. She was in a skimpy lingerie outfit that had little triangles where her nipples were. Her nipples poked out through the skimpy material by a couple of inches and they were rather thick as well so the triangles didn't exactly cover much of anything. The Slave also wore a chastity belt around her cock to stop her from touching herself. Her chastity belt however, was also quite different than the one that they had placed on me. Hers had covered her entire cock, leaving only a small hole in it so she could use the restroom with, it caused her to be completely limp with no way of touching it.

Mistress turned her attention to the other slave and nodded her head, "You came just in time actually." Mistress then stood up and grabbed the keys from her waist, "Come here, slut. I'm taking your belt off for this week. You're allowed to do whatever you'd like to this cow just don't let her climax." My cheeks tinted a red shade from the crude word, my stomach did a flip while my cock just started to throb more.

'Since when did something like this turn me on?'

The slave girl walked over to her obediently and she watched as Mistress unlocked the chastity belt. A sigh of relief came upon the slave as she felt her cock swelling up from the sight in front of her. "Am I allowed to cum, Mistress?" The girl looked at her with hopeful eyes, they were slightly watered up from how excited she was.

Mistress raised her hand up and laughed a bit, "Of course not, I'm putting the same thing she has, onto you." Mistress then reached into the bag that was nearby and put the same object around the Slave's cock, not letting her cum. The Slave huffed a bit, not liking how she had to keep wearing the chastity belt but accepting it anyway.

Mistress handed the Slave the leash, placing it into her hand, "You will be walking her around the park, I'm sure she's tired of being cooped up in here all day." She smirked and glanced back at me and my nervous expression before looking back at the dark haired slave in front of me. "There are some toys in the back I will be leaving, other than that, enjoy." Mistress then walked out of the barn, leaving us there to go about doing our business.
