I pull into my parking sport in the empty rundown carpark, the early morning sun giving off a warm glow as I step out into the early morning air, still a slight chill in the breeze. 

I sleepily unlock the heavy metal gate, it squeaking loudly as it opens, before making my way through the run down and abandoned zoo, one I brought to house and home a special animal. I say I brought, we brought it together years ago, originally just for the odd play session, he loved being locked naked in the cages, being treated like an animal, kept on display, but as time went on the sessions became longer and longer, going from hours to whole nights, to days, to a whole week, eventually I just decided not to let him out. He didn't seem to mind at first, I think he just thought that I'd extend the length of the session again, but after two weeks he started to get worried, he asked when he would be let out, I responded that zoo animals were never let out of their homes. He got a bit aggressive but quickly became docile after a few uses of the cattleprod and days without food, learning that such behaviour has negative consequences. These days he is very tame, docile and well behaved, knowing not to bite the hand that feeds him, although I still carry the cattleprod just in case he gets ideas. 

I reach the enclosure and see him curled up inside his shelter, sleeping on a bed of straw. I stare at him through the glass, enjoying the view of my special animal, his filthy naked body peacefully on full display, not caring about being seen like this, comfortable in his life as an animal on display for the amusement of others. 

I watch him for a few minutes, before tapping on the glass, my favourite creature waking with a start, an instinctive panicked look on his face as he jumps and quickly rises to all fours, the small space not allowing him to get any bigger. His face and body claims as he sees me, almost becoming excited, although also slightly cautious as his eyes glance at the cattleprod hooked to my belt, reminding him to behave if he wants feeding and attention. I move over to the large outdoor section of his enclosure, mostly flat grass, with some rocks for climbing on and sunbathing, a few items like a tire swing and even a small river, which gives him fresh drinking water. I watch with amusement as he hurries over on all fours, racing towards me, his hands gripping the thick heavy fencing, his eyes looking up at me with a desperate hunger, his legs open, showing his swollen balls and tiny caged cock straining after being imprisoned for so long. 

"Good morning, you want a treat?" I don't wait for a response, the collar around his neck prevents him from speaking anyway, I locked it to prevent him from trying to escape, making him unable to call out for help and shocking him if he runs out of his enclosure, which he did try once, quickly dropping to the floor in agony after running passed me, his fingers desperately trying to grip and pull the collar off but failed to grasp it as the shocks rippled through him, his body twitching in pain for a few minutes before I dragged him back into his home. 

I pull out my cock and slide it through the gaps in the fence, his lips closing around it immediately, his tongue hungrily exploring my head, before he push down on it, sliding it down his throat, moving back and forth, quickly earning his treat as I cum, filling his mouth with my delicious warm cum, the only warm meal he ever eats. 

I move away and make my way towards a staff only door, as I unlock it I see my captive animal relieve himself in the open, pissing straight on the grass, not caring about being seen, all sense of shame and dignity long eroded, only leaving a wild instinctive creature, one who could never return to the natural habitat of civilisation, that knowledge turning me on slightly, knowing that he will be my caged animal forever. 

I walk down the corridor and unlock the entrance to his enclosure, the smell of his home filling my senses, reminding me that I should clean it out and maybe spray him with the hose, as the naked creature racing over to me excitedly, allowing me to stroke him, enjoying the contact, the attention, the affection, the only contact with another person. Maybe I should find him a mate? I'd have to keep them separate at first as I break them and make them like him, but once they're ready I can introduce them to each other. Would he get along with another like him or would they fight? 

I snap myself out of my thoughts and picking up a bucket I hold it up, immediately getting their attention and stepping away, their eyes not leaving it. I calmly walk though the enclosure to a small trough and dump the contents into it, a smelly mixture of meat, vegetables and other foods, my pet immediately burying his head in the slop, happy to be feed, even if it doesn't look appetising. My cock grows hard watching him reduced to nothing but a mindless animal as he eats, pure instinct taking over, sometimes it's hard to believe that he was once a normal person, once planning a future together with me, one very different from our relationship now. 

I turn and leave him to enjoy his food, I have some work to do around the zoo, plus I might think more on the idea of getting him a mate. As I reach the door I turn back and look at him with a smile, I'll be back later for some fun. 

I return to my pet's enclosure, seeing them laying on the rock, his hand rubbing the metal of their chastity cage, quiet horny animalistic moans escaping their mouth, every now and then he thrusts into the air, desperately trying to relieve a primal need, one cruelly denied and blocked by the cold hard unbreakable metal locking their cock away. I smile, my own cock growing hard as I watch, it's a good time to give them another visit. 

I make my way through the corridor and into the enclosure, my captive stopping his futile attempts to play with himself, a slight fear in his eyes, possibly thinking that he'd be punished for trying to get it off. I calmly undo my trousers as I mover closer, my hard cock springing out of them, their expression changing in response, going from fear to hunger, a deep need, a clear understanding that I'm not here to punish them but to give them want they desire. 

He quickly climbs off the rock and drops to the grass beneath him, his head down and his back arched, his ass pointing up invitingly at me, as I slide a condom over my own cock, mainly to keep it clean, they've not used a human bathroom in years and they're bodily hygiene is terrible. As I approach I can hear quiet pleading whimpers, ones begging me to have my way with him. I stroke his back and he moans quietly, keeping his voice down to avoid activating the collar. 

I line myself up, their body shaking slightly with need as I press the tip of my cock against his ass, before pushing it into him hard, causing him to let out a cry, which causes him to get a shock, his body twitching wonderfully around my cock, as I begin to thrust deep, the creature breathing hard, at first recovering from the shock but quickly in pleasure from being fucked, their cock straining in their chastity, as their swollen balls swing back and forth, as my own balls slap against them. Their body shakes and trembles, a silent cry escaping their mouth as they reach a blissful orgasm, their twitching body causing me to groan as I cum. 

We both rest breathing hard, my hand gently stroking my blissful pet, his eyes closed, happily curled up next to me, content with his existence, his needs met. Seeing him like this reminds me that even though he resisted at first, he is happy here, this was his idea to buy this place, his fantasy to be locked up here like a captive animal. 

I slowly get up, not waiting to disturb him, and make my way out of the enclosure, locking it shut, making sure that he is secure and safe, before heading home for the evening. 

Epilogue: 

I move quietly through the abandoned zoo, I'd seen strange activity here, every day a man comes and enters, part of me wonders what could be going on, probably some sort of drugs related crime, maybe they're growing weed or something. Either way if I can find out what is happening here then I can get a good story and finally make it as a journalist. 

I creep through the eerie paths, empty enclosures and cages surrounding me, my footsteps echoing in the empty space. 

I jump slightly, freezing in shock as my torch light catches something in one of the glass windows. The back of a filthy looking man, one who looks like they haven't washed in months, laying on a bed of straw. Is he alive? I watch in fear and concern as they twitch awake, slowly rising to all fours, as they turn to look at me I see the shiny metal covering the cock, two swollen balls dangling beneath them, I also see the cruel looking shock collar locked around their neck, as their eyes look at me like a broken animal, no human seems to exist inside any more, just a captive creature, like any other zoo animal. 

What happened to him? Who did this to him? Why? Was it revenge? Punishment? By choice? Maybe this is more than just someone growing weed, maybe I should get out if here. 

I freeze, a wave of terror flowing over me as I hear a loud footstep behind me. Before I can turn or react I feel a hand clasp over my mouth, keeping me from screaming and holding my head in place. As I reach into my pocket for anything to fight back I feel a sharp sting in my neck, my limbs quickly going limp and numb, my heart rate slowing, my breathing growing shallow, my eyelids getting heavy, my limp body held in the arms of my attacker, their hand gently stroking my head. 

"It's alright, don't panic. I see you've discovered my pet, he likes living here, so I can't have you escaping and telling the authorities, cause they'll take him away from his home. Don't worry though, I won't hurt you. While my pet likes living here, he does however get a bit lonely. I'm sure you'll both get along once you get settled." What!? I stare at the docile creature trapped and imprisoned inside his enclosure, his empty eyes looking at me, as I see what is to become of me, what I will be turned into. I must escape, I must get free, my body refuses to move, my mind growing foggy, unable to think, my eyes refusing to stay open, my horrifying fate sealed as I go unconscious, my limp body dragged to my own enclosure, my new home, to be trained and broken like the pet I'd discovered.
