I happily enter my home after a weekend with Rex and his owner, I always love seeing Rex, and I know Rex loves spending time with me, and his owner is nice to me but after a few days I miss my owners to much. Now I'm home I miss Rex a bit but I'm pleased to be with my owners and ready to sleep in my own dog bed, not that I did much sleeping with Rex. As I walk inside something feels strange and different, what makes things even stranger is that my owner hasn't removed my leash for some reason and is instead leading me towards the living room.

"We know that you enjoy Rex's company, plus you are friendly with Jack and Fifi, and for a while we've been talking to someone who has seen pictures and videos of you online and who would love to be your friend. I want you behave and be a good boy. He might be nervous when he first sees you but just be friendly." I look at my owner confused, what does he mean? As the living room door opens someone else is in the room with my other owner. Naked and on all fours the young stranger stands, his hands locked in mitts and his ankles chained to his chastity cage, similar to how I was when I became a pet. Is he staying with us? I watch as he looks at me with a slightly worried look, his eyes looking at my various modifications, my shorten fingers, my amputated feet and my removed balls, maybe he didn't fully understand what he signed up for, if so he doesn't deserve my owner's love and I now have to deal with looking after the idiot. I walk up to him and sniff him, at first he flinchs but reminds still.

"This is Rover. He's your new friend and will be living with us from now on. I need you to help look after him and train him, teach him how to be a good boy like you. Understand?" Never wanting to disappointed my owners I accept my new duties, even if I don't like the dumb pup.

"Woof!" I watch as he seems surprised, did he think I'd talk like a person or something?

"Good boy, we'll leave you two to get to know each other." With that they unclip my leash and give me a loving stroke on my head, before walking out of the room and closing the door behind them.

We stare at each other for a bit before I get bored and I playfully jump and yelp at him to see if he wants to play but he just flinchs and steps back unsteadily. Trying to explain to him I pick up one of the balls in my mouth and roll it over to him, he seems to understand and smiling he rolls it back, I make a point of panting to show him how to properly show happiness, smiling is a human expression and not proper behaviour for us. We play for a while and Rover gets more relaxed around me and seems to enjoy being a puppy, maybe I miss judged him, I remember being nervous when I began this life, hopefully just like me he won't regret it and learn to love his life and family, our two loving owners and me his big brother. Tired I yawn and walk over to my bed, which now has a second one next to it, and collapse down on it, as I rest I feel Rover watching me unsure of what to do. As if copying me he also lays in his bed, I hope he won't be like this all the time, following and copying my every action but I suppose for now he is learning so I can live with it. Exhausted I close my eyes and quickly drift off to sleep, my new brother nearby keeping me company.

I awake to a paw tapping me, opening my eyes I look up to see Rover looking desperately down at me and whining, seeing his cock straining in its cage I can guess what he needs.

"I need to pee." I growl at him, telling him not to speak. I get up and move to the still closed door.

"I..." I growl once again, this time the message seems to get through his stupid head. I whine and paw at the door loudly and then back away and look at Rover and then the door, it takes a few seconds for him to understand but he moves towards the door and acts as I had shown him. I feel a slight wave of pride as I succeed in teaching the young pup, although he almost doesn't step back in time as the door opens, which lessens it a bit, I think my younger charge has a lot more learning to do.

"What's up?" The dope just looks up at our owner pleadingly, I walk passed makimg sure to push against our owners leg and make my way to the backdoor and sit, Rover follows me and sits, although not as still as me, his front paws constantly moving impatiently as the door is opened. I quickly move outside, looking back I see Rover step out hesitantly, I walk back and walk with him, hoping to reassure him that everything is fine and that he is safe here. Once we reach the grass I see him prepare to pee but seems unable to, knowing what to do I force myself to go, pissing claimly onto the grass in full view, moments later I hear Rover finally relieve himself and returning indoors he pants happily.

As we stand in the kitchen two food bowls are put down and I excitedly go over to my bowl, Rover slowly follows and looks down at the bowl of cold cooked mince meat and vegetables, seeing that for some reason he doesn't seem sure about our delicious dog food, given to us by our loving owners, I lick my lips trying to tell him to enjoy the meal, not doing so would be an insult to our owners ams also juat stupid, it's food. He slightly awkwardly lowers his head and begins to eat, quickly speeding up as he hungrily eats his dinner. Knowing that he is now eating I return to my own dinner and f9cus on happily ending my hunger.

Finishing our meals I head back into the living room and lay down on the floor as the smell of my owners cooking fills the air, making me feel slightly hungry again, Rover on the otherhand seems to be struggling slightly, maybe he's not used to meals not making you feel full but only removing hunger. My mind sighs slightly as I get to my feet and get a toy, I'm not really that playful right now but he seems to need a distraction of some sort. I roll the ball from earlier towards him, noticing it he looks at me as I pant playfully, he knocks it back and we both begin to chase the ball.

We stop as we hear our names being called and race each other into the kitchen, being far more used to being on all fours I make it to my owners before Rover, who seems amazed by my speed. I sit patiently on the floor next to the table as my owners eat, rover just stands mindlessly staring as they eat, his mouth watering at the sight. I gently take a small piece of food from my owner as he gives me a stroke.

"Good boy." I look over at Rover as I lick my lips, he seems jealous but quickly sits as I do, with his back legs tucked under his butt and resting on his front legs, both of us rewarded this tike for our good behaviour.

As our owners sit back and place their cutlery on their plates, they both undo their trousers and pull out their cocks, instinct and training take over as I mindlessly walk over to one of them and begin to hungrily lick and suck his cock, enjoying the smell and taste of his crotch and working for my delicious reward. Out of the corner of my eye I can see Rover walk up slightly unsure and watch me as I serve my master without hesitation or embarrassment at being seen doing so, those are human concepts that he needs to abandon and forget. I watch as he takes our other powers cock and begins to make him happy, as he tucks on their cock I can tell that they're enjoying it as well as their cock strains in its cage. I return to fully concentrating on my task as I fully enjoy the moment, quickly being rewarded with my favourite treat, warm cum, as it fills my mouth, I savour it as I greedily swallow it down.

Licking him clean of every drop of cum I sit back as he puts his cock away and strokes me on the head as I pant happily and lick my lips. Noticing the Rover was still busy earning his treat I decide to take some time to be alone and walk out of the kitchen and rest in the living room, taking a moment to just be on my own. Looking after the pup was a very draining job but I won't let my owners down, I'll make sure that he learns how to properly behave. I lay down on the floor and close my eyes as I enjoy the peace and quiet while I can.

I wake up to a dimly lit room, the light from a couple of lanps and the TV illuminating my surroundings. As I rise to all fours I stare at Rover as he is stroked and fussed by my owner, jealousy swells inside me, he's stealing the love and affection that is mine.

"Are you getting jealous? It's alright, come over here." I turn and see my other owner and move over to him, my eyes closing as he strokes me.

"See, there's nothing to be jealous about, we still love you just as much as we did before and you will still get plenty of attention." I lean into him as he scratches behind my ear. Mayhe he is right, two owners should have two pets to love, they can't both fuss me at the same time. I still feel a bit jealous but my owner's touch is making me feel much better.

"You two behave now and get some sleep, no fighting, we love yiu both, goodnight." I curl up in my bed as they turn the lights off and leave, their footsteps echo loudly in the quiet night as they go upstairs to bed. As I settle I sense Rover move towards me.

"H..." I give an annoyed growl, just cause our owners our in bed doesn't mean that he can speak, this pup has a lot to learn, being a big brother is exhausting. I hear him let out a whimper, looking up I see him look unsure and he turns his head to look at his empty dog bed and whines a little. I readjust in my bed, giving bit of room for him to curl up in front of me and I rest a paw on him, as he settles. As he closes his eyes and relaxes I close my own tired eyes, although he is a bit irritating and annoying and still has much to learn, having a little brother isn't all bad and it's nice to not be alone when my owners are asleep or when they're out, I guess that I can live with this new change to my life.

Epilogue:

I walk in from another weekend with Rex and I'm immediately greeted excitedly by Rover, who jumps around on his now modified limbs, like me his fingers are gone, only the bottom third remaining, his feet are gone and his cock hangs limply without his balls. He gives me a few friendly licks and I happily join him in the living room to chase a ball with my little brother.
