"Hmm, well, I think we should make sure that you remain obedient to us. So let's remove your ability to milk yourself first" she says while injecting your hands and feet with another syringe.
You watch as your hand begins to bubble and grow as it starts to reshape. You lose all fingers as they absorbed back into your now solid mass of hand flesh. The bubbling mass then starts forming the familiar shape of a cow's hoof. You can only imagine that the rest of your limbs are also now ending in cow hooves. That certainly makes it impossible to milk yourself, but thanks to the first serum, you are so relaxed that you may fall asleep even.
The woman then looks over at you and chuckles at your disproportionately sized hooves to your wrist and ankles. "My my, we will need to fix that or you may snap them. After another few rounds of injections, all four of your limbs have been fully replaced by cow legs. "There we go sweetie, now you are fully dependent on us. Oh didn't I mention this before? When I said normal world, I really meant it that I didn't mean as a normal person. You are always and will always be our property sweetie. You will be let outside into one of our pastures is all. Essentially just another cow. Speaking of which, let's make that correction right away too."
She walks behind you and you feel a sharp sting in your crotch as 2 needles are stuck into you. You cant watch as your cock is slowly sucked back inside of you as the folds of your new bovine pussy begin to develope. Another injection starts growing out what you assume correctly to be your tail and new asshole as well. From tail to hoof, your lower half was practically all cow.
You let out a weak moo-like moan, something that has become one of the remaining few sounds you were capable of making, as you feel the new emptiness between your legs; and a new urge to fill it. "Oh don't worry, that sudden longing for fullness is because you are in heat, Sweetie. If you are a good girl, I may even breed you as a reward. But you will need to earn that privilege. My, aren't you such a cutie!" She says holding up a mirror for you. You had not realized it but one of the injections apparently had done a number to your face, as now, quite a cute girl was looking back at you. "Moooo?" You moo in a calm confusion.
"Like it? I am sure you are pleased. Plus, who really cares really what you like or not, right? One last thing I think" the woman says as she pierces your nose with a golden septum ring that is large enough to touch your upper lip. "There you go. Oh, and I must admit, I lied earlier" she says before a searing pain shoots through your ass as you are branded. "Now we are finished." This is the last thing you remember as you pass out after that.
When you wake up, you are in a new place. Some kind of barn from the looks of it. You try to stand up, but only manage to get up onto all fours, as your new cow limbs and hips no longer support a bipedal lifestyle. You bellow out a moo, which immediately calls over the same woman from before. "I see our new girl is awake again. How are you feeling Sweetie?"
You let out a sarcastic moo in response, knowing full well that you can't actually speak, and that she already knows this and is just messing with you. But you still respond because you remember the deal you have with her. You be a good girl, and she will breed you. The feeling of emptiness is constantly in your mind and you are annoyingly horny. The concept that you are now a girl was slightly dulled thanks to this and the calming serum from earlier still being in effect though, so you are taking it far better than you normally should have. Also, you are desperately in need of a good milking. So if being complacent means getting milked quicker, then so be it.
You are lead out of the "barn" which had apparently just been a decorative interior. You were still inside. You are lead by a rope attached to your nose ring down a hallway and into another room that was interesting to you. Inside was a window that had quite the familiar view. The window was of the room you spent the last month stuck inside of. They were watching you the whole time. Then you saw it. The big white board with each uddered human's harness number, associated with a percentage; a percentage of their submission and allotted production rate. The higher the submissiveness, the lower the production.
This meant that your full submission only took a month, and you were not in fact lowering in productivity rate, but were being forced to do so. Honestly you felt insulted, but for all the wrong reason. You felt insulted that they lowered your rates. Not by the fact that they were only making you submissive with this set up. "You were one of our fastest girls you know. Just a month for a full conversation is honestly quite impressive. Half of those still inside have been there for at least 3 months now. And a quarter of them have been for over 6. Those one are quite the defiant ones, but they all eventually will break in time. You were in and out, which has earned you a bit of special treatment you know. Most of them will be sent straight to their new assignment facility. But I am choosing to keep you here as my special, personal pet. Of course that also comes with special privileges, such as retaining your intelligence, and the option to earn rewards with good behavior. And don't worry, we will bring you back up to your normal production rates. That was just an excuse we use to put the final nail in the coffin of yours and their submission. Even if you now know what really was going on, do you feel like suddenly rebelling or causing trouble? No? Then you understand what I mean" said the woman on this guided tour. She was right. Even now with this information, you were still behaving and being obedient. You wanted to breed and get milked, and those two goals were your new primary driving forces. Rebel? Why would you? Who would milk you then if you did that?
You just follow your owner over to another facility where you are excited to see a few similarly shaped woman are being milked, and an empty stall. "Ladies, this is the newest member of our special group. Please treat her well. She is quite the producer too. You will be her guide Sally. Show her the ropes. Her name is Kara by the way" says the woman as she leads you over to the last empty milking station.
The other 4 cowgirls watch you with sympathetic but slightly dulled black eyes. All 4 of them had full cow eyes, and you imagined that was the same for you as well now. That must be why things look a little differently now to you. You are hooked up to the machine and it turns on, relieving your painfully full udder. Your new owner leans down and whispers into your ear before she leaves. "Welcome to my family Kara. I made it possible to communicate to the others, but only through mooing of course. Your mind will translate for you too. So learn quickly, and you will enjoy your new life here, I assure you." She gets up to leave the room, and in the doorway, turns and says to you one last thing. "Did I mention that I am planning on starting up a sort of petting zoo using the 5 of you girls?" Then she leaves.
