Mowgli was exploring the jungle one lazy afternoon, trying to find cozy spots to lay down and relax the rest of the day away. He finally found a nice, moss-covered rock with just enough dappled sunlight to keep him warm, but not too warm, and just as he was about to fall asleep, he felt a prick in his neck, but before he could even process it, he fell unconscious. When he woke up an indeterminate amount of time later, he found that he was laying on a soft bed of hay.
"Wait, what's going on, where am I?" Mowgli said almost immediately after waking up. He was quite surprised to hear a boy around his age say, "So you're finally up?" Mowgli looked over to see a fair-skinned boy with dark blonde, wavy hair and deep blue eyes staring at him with intrigue. The boy was clad in only a black speedo with a white number on it, and was sitting cross-legged on the hay nearby, blanketed in morning sunlight. They were in a large barn, and the morning sunlight peeked in through the windows. The part that really surprised and amazed Mowgli, however, were a few quirks of the boy's appearance. He had a small pair of cow-like horns sticking out through his hair, along with a long, cow-like tail complete with a tuft of blonde hair at the end. The tail swept gently from side to side. On top of that, the boy's speedo contained a surprisingly large, basketball-sized bulge, and he was quite fit-looking, not super muscular, but definitely stronger than the average boy.
Mowgli said, "Wait, what is this? Where am I? Who are you? How can I understand you? I don't speak much human." and the boy said, "I'm Danny, and I have a lot to explain to you. What's your name?" and Mowgli said, "My name's Mowgli! I'm from the jungle!" and the boy said, "The jungle, really? That's so cool!" and Mowgli said, "Yeah, I guess it is! Now get to explaining!" and Danny smiled, saying "You're a feisty one! I like it! It's rare for a boy to become a milk cow, and yet you're not subdued or submissive at all!"
Mowgli merely said, "What are you talking about?" but he looked down, only to see a set of udders right below his belly button. It was pink and bulged out only slightly. Under that was a black speedo with a number on it just like Danny's. Mowgli screamed in surprise and panic. He looked behind him, only to see a brown tail with a dark brown-haired tip right at the end, quite similar to Danny's. He reached on top of his head, only to feel a pair of short cow-like horns just like Danny's. Mowgli said, "Wait, I'm a boy-cow too?" and Danny said, "Yeah, they modified us while we slept. It's happened to all of us. That's why we can understand each other's speech. Most boys become a breeder cow like me." and he gestured to his massive package, then said, "But for some reason, you grew udders like a milk cow."
Mowgli said, "Wait, so am I gonna be milked? Treated like cattle? I'm a boy you can't do this!" and he stood up, only to feel something pulling at his ankle. He then looked down to see that his ankle was chained to the ground. Danny said, "I'm sorry, but also, I didn't do this to you. I can't let you go, either. You don't wanna know what they'd do to me." and Mowgli sat back down, saying, "Fine, so what's a breeder do? Why are you here?" and Danny said, "Well, we breeders don't just spend all day making calves. We actually don't even do it that often. We mostly just milk and feed milk cows like you. I'm here to take care of you and try to make you productive. For some reason, you don't produce much milk out of your udders or your chest for that matter. Fattening you up might help, it usually does, but the research people might have other things to try too."
Mowgli said, "And what if I don't wanna?" and Danny said, "They have ways of making us do what they want." and he looked down, saying, "I don't wanna talk about it." and Mowgli said, "Ok, I get it." and Danny said, "You actually got it pretty good! All of the milk cows get pampered, spoiled and fat while we breeders have to do all the work!" and Mowgli said, "But I just wanna go back to the jungle!" and Danny said, "Just try to make the best out of it. You might like things here more than you think you will!"
Danny sat next to Mowgli and talked to him for a bit, trying to calm him down and make him feel more comfortable. He offered to feed him, and even offered to give him a soothing massage that might make him feel better. Soon afterward...
