We had been asked not to speak to each other, so the six men sitting next to me and I were skimming through the booklet they had given me, while occasionally taking a peak at the guy sitting on the bench on the opposite side of the room.
When our gazes met, he instantly returned to reading his booklet that looked very similar to ours, except that it had a dark blue color, while ours was pink. In addition to a short "congratulations note", the booklet explained the process we were about to experience in detail, also including various pictures of the transformation.
The transformation chamber would first start by removing all of our body hair, and generally regress our bodies to skinnier, more-petite and feminine form. It would then continue to increase our hips, slender our waists, increase the length of our hands and shorten our legs to make us able to comfortably stand on all fours. It would then force us into that position by re-arranging our bones and our spine to make us true quadruplets. And of course hands and feet would look ridiculous on us, so they would then be replaced by dark, hard hooves that would truly make us depend on our human caretakers.
Subtler changes would also include the modification of our voice boxes to only allow us to "moo" in various ways for communication with each other and humans, and a complete overhaul of our digestive systems to change our diet to grass, hay, grains, fruits and vegetables. More significant changes would include the change of our skin into fur of white and black patches, the addition of two massive milk-filled breasts, the replacement of our penises with an ever-wet vagina, and a small tail to keep the flies away from our backs.
Of course I had done my research, so I could imagine what the pictures in the dark blue book looked like with a bull's transformation going a similar way, but making him even bigger, heavily muscular, giving him two cute horns and of course the addition of a massive bull's penis that would become our sole source of pleasure going forward.
I was the first in line, so I followed the nurse quietly into the transformation chamber. I was hardly listening to what she was saying, but followed her instructions to stand in the middle of the chamber and wait for the high-tech machine to start its work. I almost jumped when it notably started its power-up phase with a loud buzzing sound. Only seconds later, my whole body felt like it was burning, and I could feel my bones and muscles shape and being re-arranged by the strange machine. I wasn't sure if the machine then sedated me, or if I passed out from the intense pain that I then felt as part of my transformation.
