Suddenly 4 clamps encase your limbs completely, locking you in place. You feel a warm sensation in your hands and feet which no matter how hard you try, do not budge from the clamps. You can hear cracking sounds, which you worry about, but are not sure where they are coming from.
"Udder growth insufficient!" Announced a mechanical voice, followed by 4 injections being stabbed right above your crotch. That area warms up like your hands and feet did too.
"Reproductive capability negligible!" Came the voice again. A large clamp encased your rear end, with your legs and midriff poking out through perfectly sized holes. That too warmed up as well.
"Ears insufficiently sized!" Sounds the voice, and the world goes silent as a pair of suction cup like tubes slide over your ears, as they too warmed up.
You look around, seeing the scientist watching you through the window in disbelief and regretfulness. Apparently he had found no way of stopping this. And could simply watch it happen.
With a pop, the world regained sound, and you tried to look at the damages. But couldn't quite get a good look.
"Muzzle stunted!" Came over the speaker system, followed by your jaw, nose and mouth being forced into a mask.
You heard a mechanical hatch open up, and a cool breeze touch the base of your spine for a brief moment.
"Horns lost!" A headband-like mechanical arm is fixed around your skull and causes your temples to warm up.
After another few minutes, you hear the sound of pressurized gas being leaked out, and all clamps and mechanical parts touching you split apart and retract into the walls. What is left of you is the body of a mutated cow. Your body is just like the other cows now, complete with an enormous 4 teat tipped udder squished between your hind legs. It looks closer to 4 boobs that merged together than a normal udder, and was nearly twice as large as the other mutated cows too.
Your hands and feet were now hooves, and standing on two legs was out of the question. Your new tail swished above your brand new sex, while highlighting your now significantly larger ass.
Your muzzle protruded from your face a good few inches, and now carried your nose on top of it too. And all of your teeth have been turned into molars, perfect for a grass only diet, and little else. You can't see them, but you also know that a pair of sharp horns now adorn the sides of your head, along with your longer cow ears.
You begin to panic and start moving around, causing the alarms to go off again, and mechanical arms to restrain you again. A visor is held in front of your eyes, and some noise is played. On the screen, some kind of imagery is shown, but you don't know what it is. However it is calming you down significantly. Soon you stop worrying about most things, even about becoming a mutated cow. The visor returns to the wall, and you just idle in place as you are moved into the last empty stalls in the milking parlor. The side wall opens up and you are lead out after your nose is pierced with a ring, and your left ear is tagged.
You waddle into place above some kind of box, and begin munching on the trough full grass before you. You suddenly hear a buzzer and feel 4 cold tubes slide over your teats. You look around for a moment, the the milking begins, and you grin as your overfilled udder is made to feel really good as your milk is rapidly drawn out of it. You go back to eating while you are milked, all the while feeling really good.
A door opens on the far side of the room, and a guy in a white coat rushes in. You can't remember where you seen him before, so you just ignore him. He runs over to you though. He begins touching you, playing with your hooves, pulling your long hair, your tail, etc... it's pretty annoying. You moo loudly at him and look at him with frustration from having your good feeling ruined. This causes him to back off for now, so you return back to your eating.
A while later, another buzzer sounds, and the gate to your pen opens up. But you are no where near empty yet? However the suction cups retract and leave you with a still full udder. They only collected the excess. And while it wasn't as large, your huge udder still squished against the inner sides of your hind legs. So you protest this by staying standing in the pen. The scientist guy watches you, so you moo loudly at him and move your head down to look at your udder and the box in the floor.
He gets the message and moves over and presses a button. The suction cups return from the box beneath you, and you are milked once again. This time until you are adequately emptied. Though your udder still is much larger than the other cows. At least your legs are not being forced apart, and only a little bit of udder squishing is happening.
