I stand naked wearing nothing but a dog collar and watch as my partner flicks through a large ancient looking book.

"Here it is." I looks up at me seriously.

"Our you sure about this? It should only last for a week but I have no idea how it will affect you long term." I smile excitedly, I've wanted this since forever and since learning of his sorcerery and magic powers I've been asking him if he could do something like this. He finally learnt to spell and promised to perform it for my birthday, we've roleplayed with puppyplay before but this is so much more extreme and exciting, with this spell we won't be limited to remaining indoors or other restrictions.

"See you in a week." I watch as he begins the incantation and I feel a wave of energy flow over me as the air ripples as everyone's perception of me is warpped, to everyone except my partner I'll be seen as nothing but a dog, even other dogs will see me as one of them. I feel my stomach and tongue alter as I'm made able to live off of only dog food, my taste buds and sense of smell changing, becoming more sensitive, smells that may have repulsed me before are suddenly appealing and attractive, such as the scent of my partner's sweaty crotch and his ass, forcing me to make myself stay in the circle rather than walk up to him and sniff. I feel my mind tingle as my intelligence is reduced, part of my brain worries as I forget facts and concepts, but that part of my mind is quickly lost to the msgic as well, as I fall to my hands and knees, my knowledge of walking and balancing on two legs blocked and no longer accessible, almost as if forgotten, magical seals cutting off large chunks of my brain.

I stand on all fours as the strange feelings fade, my mind blank, barely thinking, running off instinct, no worries, stresses or concerns, no dreams or ambitions, no plans, no memories, no identity other than that of the animal I now am, my mind rewritten, my behaviour modified to that of a simple well behaved dog, my mind unable to think anything complex. I look up lovingly at my owner as he smiles down at me.

"Let's see if it worked. Sit!" I find myself unable to understand some of the words he speaks but the instruction is clear and I sit as instructed, almost as if desperate to please my owner, my ass resting on my lower hind legs.

"Good boy." I pant happily at the news that I pleased him.

"Speak." Having completely lost the ability to speak, the knowledge taken by the spell, my new and limited vocabulary fills my mind, barks, panting, whines, whimpers, howls and growls are all the language my reduced mind can manage.

"Woof!" My tongue hangs out as he strokes me. I watch as he undoes his trousers and his hard cock springs out, the scent that already attracted me now overwhelming strong as I fixate on it as he moves up to me.

"Beg." I rise up on my knees and bring my front legs up, my hands flopping down as I pant and whine, my mind desperately craving his cock.

"Good boy, sit." I drop back down obediently, somehow knowing that good behaviour is rewarded.

"Suck." I excitedly sniff and lick his crotch, his smell and taste filling my sense as I slide my mouth over his cock and begin to suck on it hungrily, my tongue exploring him as I move my head back and forth, pushing his cock down my throat. My work quickly rewarded as his warm cum fills my mouth, my new taste buds finding my treat overwhelmingly delicious, as I swallow it down. As his cock pulls out of my mouth, I can't help but lap at it, eagerly collecting every single drop of his cum.

"Good boy." I pant happily as he strokes me, I rise to all fours as his hand runs down my back, the feeling is amazing and wonderful, so much that I feel my cock begin to grow.

"Good boy. Although I'll have to do something about that, good thing I booked an appointment this afternoon. Unfortunately removing part of your body breaks the spell and makes your transformation permanent, but I don't think you'll mind, it's what you wanted after all." I barely understand anything my owner says and continue to enjoy the attention, panting happily, I'm sure whatever he is saying he has the best intentions for me, my owner knows best.

"Would you like to be my puppy forever? Yes you would! Yes you would!" I'm not entirely sure what he's saying but he is making it sound so exciting, yes I would love to be his puppy forever, of course I would.

"Maybe once you're fixed we can think about getting you a boyfriend to play with." I only word I understand is play, which makes me feel excited.

"Woof!"

"Someone seems excited? Do you want to go walkies?" Walkies? That sounds fun. I want to go walkies.

"Woof!" I feel a leash clip to my collar and follow my owner as he tugs. As the front door opens I step outside, not caring that anyone can see me, the presence of my owner and the fact that he is holding my leash making me feel confident and safe as I enjoy our walk together.
