I rest curled up, comfortable, content, the night couldn't have gone any better. I hear my date peacefully sleeping above me, clearly they also seem happy with how things went, their light snoring telling me that they're in a deep sleep.
I look out through the bars of my cage, my new bed and possibly where I'll be kept when left alone, the metal bars surrounding me making me feel safe and secure, my new owner locking me safely away, protecting me from both myself, other and the outside world, making me feel special and valued, his protected possession, his loved and cared for pet. He even left me a bowl of water to keep me hydrated through the night, looking after me even as he sleeps.
We'd only ever talked about this, our date was just a first meeting to see how we get along, it wasn't supposed to end this way, not yet. Now here I am, naked, collared, locked in chastity, trapped in a cage, reduced to nothing but a helpless pet. No one even knows I'm here, I kept the date a secret, we met in a quiet public place, no one will come looking for me here, no will disturb me and my owner, no one will take me away from them or my life as their pet. I'm his puppy forever now and I couldn't be happier, it's been my dream to be owned like this for so long, to be collared, to be able to just be the puppy I am deep down inside.
I didn't fight back as he placed the shock collar around my neck, forced me to remain on all fours, told me to never speak like a human again, I panted happily as he stroked my head and back lovingly, I remained still as he locked my cock away, I obediently followed on all fours as he walked me on a leash in his back garden, I pissed on the grass like any other dog, I didn't resist as I was instructed to get into my cage. I remember his words as he stroked my head and kissed me goodnight, he told me how much he loves me, how he will keep me as his forever, how he will train me and care for me, and that if I'm good he'll modify my body, make me a true dog, one who doesn't have fingers or feet, who can't grip and hold items, who can't walk on two legs. I feel my cock twitch in its cage as I remember giving him a blowjob through the bars of my cage just before the light went out, the delicious taste of his treat lingering in my mouth, I wonder if he'll also get me fixed, relieve me from my chastity and the frustration it causes. Whatever master has done with me, I'm sure it will be for the best, he wouldn't harm his pet, I trust him completely, plus if it will make me a better pet then I have no complaints.
I close my eyes and listen to my owner snoring, happy to be so near to them, grateful to be their pet, happy to have such a wonderful end to our date, excited to spend the rest of my life with them as their loyal, obedient, loving puppy.
