Still, the next month has been a very busy one. Rainbow and her owner moved to live in a big country house.

Her owner has set up the new training room for the pegasus.

It was impossible for Rainbow Dash not to obey her Master's every request. With more moans and gasps coming out of her mouth, Rainbow Dash could feel herself getting closer to her new being.

But with each and every change she felt more and more pleasure; she felt a little less and less like her old self. There was a small twinge of guilt at her thoughts for feeling any discomfort, but it quickly faded away as she started to enjoy her new self. She didn't know exactly when she would notice it, but one day, after being given some special training, Rainbow Dash had discovered a small part of herself that had felt at home. She had been so scared to find this out, but she had slowly but surely pieced together that part of her that felt more like a bitch than anything else.

A little voice in her head told Rainbow Dash that this was what she needed. It didn't matter that her old life has been destroyed.

She had improved immensely, and he was looking forward to spending more time with him as she trained to become a better dog. It was amazing to Rainbow Dash knew that Master had spent so much time teaching her about submission and obedience.

Each and every day of obedience had a certain effect on Rainbow Dash. She knew that she loved it. Every time her Master looked her in the eyes and told her to obey, Rainbow would become more and more excited.

Every time Master ordered her to do something, her body responded.

She was not silly any more. She already learned many commands. "SIT", "DOWN", and "PLACE". It could even execute the "WAIT" command for some time.

Each time she did not submit, she was punished by her own body. Her tail drooped down. Her breathing quickened. Her heart seemed to be racing faster as her heart rate slowed down.

Every time she felt that new wave of pleasure and heat that rippled through her body, she knew that she would never again be able to say no to her Master’s demands.

Master was always going to give her what she wanted as long as she did as he was told. She waited for Master gave her a reward. Every day that passed, Rainbow was made to crave more of her Master's hooves, petting her body. Each day Master made her want to do so, and every day she spent time around her Master, she wanted to do so even more. Every time he did it, she was instantly drawn to the spot where the hoofs were touching her. Each time, she would obey with more and more enthusiasm. She became addicted to Master's hoof rubbing.

As time went on and her Master continued to tease her with her new changes. Her brushing fur became longer and fluffy. Her heat became permanent. She could run and fly but no longer felt like a pony. She didn't hate it...not really. She was now the hot, slutty little hound. So what if her bitchy body was to become more petite? She would be a happy, horny little puppy on a leash, serving her master as faithfully as she could. She wanted to be a pet forever!

* * *

The Rainbow was lovely and cheerful, but every day she felt the heat, and she wanted to cum so badly. Only the unwillingness to be punished and disappointment in the opinion of the owner constrained it.

The last time Master had had this much fun, Rainbow had been an obedient animal. She had not begged or pleaded for release, just obediently followed his every whim. Now, she could feel it. She could feel how close she was, how much she wanted this to end. She let out a long, low growl and turned her head over to meet Master's gaze. Her muzzle was now a dull red, a sign of her arousal. She had forgotten to hold back when Master had first given her a good hard spanking, but she hadn't forgotten what it felt like to be petted, a reminder of all the things she had learned from her master.

Her head was starting to spin from the intense pleasure, and she could feel her legs trembling in anticipation as Master's hooves started to slowly rub her sensitive skin. Rainbow Dash knew he was going to reach for her.

She could feel her muscles start to melt off with every touch. As the pleasure in her body started to overcome her senses, her mind had already started to accept the idea of cumming. She knew that Master was not going to make her cum. She tried not to think of anything but the constant pleasure, as each patting sent ripples through her body, making her wet with anticipation.

Master began stroking her new pet's ears, watching her helpless body writhe as she was forced to beg for more. Her whole body felt as warm and supple as a newborn baby, and every part of her began to feel like a wet toy. She knew that with each moan that escaped her mouth, orgasm awaited her, ready to burst from Master's hoof. But even with this knowledge, she did nothing but moans and pants as owner's hoof rubbed her ears over and over. Her tail was wagging harder by the second, as if telling Master that she was doing exactly as requested.

“I'm a good dog now” she moaned.

"That's the spirit, dog!" called Master. "Let's make this a regular thing! I want to see you start panting and shivering. More like a real dog! Do it, pet."

Her tail kept wagging and it sent shivers of pleasure down Rainbow Dash's back. Master's hoofs continued to rub her ears, rubbing them vigorously to her sensitive nerve endings every time Master touched her.

"You were a good dog and you deserve a good award", he said and left the room, leaving Rainbow to writhe on the floor.

The owner wasn't there for some time. All this time the Rainbow struggled with herself not to press a hoof to the pussy. It was the most painful several minutes in her life.

Together with the Master, a huge black Rottweiler entered the room.

The canine's body was so strong, so rugged. The Rottweiler's eyes were like fire, looking into her soul, her memories. The Rottweiler gave a growl as its eyes focused on the pegasus and it opened its mouth. The Rottweiler's jaws were filled with razor-sharp teeth and its tongue wagged madly. Its claws were sharp. Rainbow Dash's eyes flashed open and she could hear the blood rushing in her ears and her body. The Rottweiler raised its head and its muzzle began to tilt, its mouth opened wide and its eyes began to glow. As the Rottweiler's eyes were glowing, the muscles in its neck bulged as it growled. A powerful roar erupted from its body as it lunged at Rainbow Dash.

Rainbow Dash gulped. Her heart was pounding fast as she tried to take a deep breath. She looked at the Rottweiler's massive form as its gaze was fixed on her. But it was not just a dog. It had been bred to kill.

“This is your new mate for the rest of your sex life. Just like a true bitch!" Master smiled.

She felt the Rottweiler's muzzle close around her and held her breath as the massive dog's tongue darted out to lick her nose. Her ears were burning as they felt like they would singe as it licked at her. Her heart was in overdrive as she felt the heat radiating from her face. She opened her mouth and felt its thick tongue go to work on her tongue. Her muzzle was now full of its hot saliva.

With her new found confidence, Rainbow's body started to sway like a dog, her tail wagging furiously. She just wanted to be bred. She started breathing rapidly, her body convulsing. Her pussy began to burn, her eyes burning in an erotic desire to be violated. Master had never fucked her. He was only waiting for the right moment to take her to breed her with other dog.

The heat that felt like torture was now just an added bonus as she let loose a primal howl that made it impossible to speak.

Rainbow was filled with lust, and now she had an insatiable pussy for the Rottweiler to use, all she had to do was give in to her animalistic urges. She fell on her knees, firmly raised the croup and presented her pussy to a Rottweiler.

"Get her," commanded Master. The huge dog barked again and jumped up.

The dog licking her pussy furiously. She had never felt better. The intense heat was just as strong this time, and when the dog reached her clit her mind was so much clearer, her body was more relaxed and her legs were no longer shaking violently. The dog then began to lick her pussy again, sliding her tongue moving back and forth and back up and down.

Her mouth opened up and her tongue fell out. . The dog barked angrily and dove for Rainbow's pussy, as it moved across her slit, up and down, up and down, over and over.

The Rottweiler jumped on Rainbow Dash's back and began to rub its thick tongue over every inch of her exposed body.The Rottweiler began to lick the back of her head and neck, her tongue darting and licking around. After a few minutes Rainbow came down from her orgasmic high.

"Aagh!" she moaned, as her juices coated the room and ran down her thigh. The dog jumped up and sat on her back. She felt it slap the front of her thighs, his hot breath in her ear.

She felt its teeth on her withers.

Her ears swiveled in alarm as the big dog's huge prick, the head the size of a grapefruit, plunged inside the back of Rainbow Dash's vagina. She felt something hard pressing against the bottom of her pussy.

She didn't know what to do so she just moaned, like a dog that never let a cock out since she was born. She looked at it, not believing what was going on. Was she getting bred or was this a special way for her to have fun?

Then she let it out, a deep and guttural growl as it pounded Rainbow Dash's pussy with a hard, fast rhythm, until it felt like its cock was going to explode. Rainbow Dash wasn't sure if she was still screaming or was just thinking incoherently.

The dog stopped its assault, still pounding the pussy of its new mate, but it put its paws together and started to grumble, its throat rumbling with pleasure.

The dog purred again and started to growl its pleasure out.

The creature thrust relentlessly in and out of her, its thick cock filling Rainbow Dash's tight cunt, making her feel even more horny than she already was. It felt so good, so right, her entire body felt hotter as the canine filled her.

Her body convulsed, making sure that the dog would fill her pussy completely. Its cock was so large and hot, and it made she shudder even harder than she already did, unable to stand the full feeling of its throbbing cock inside her.

Her stomach was writhing as she felt the dog push her limits, its length almost forcing her to spill her juices over the floor.

Rainbow didn't care. The dog was pounding her wet pussy so hard, pumping its full length in so deep. She started to squeal loudly in ecstasy, tears of joy streaming down her face. The doggy was forcing its enormous member deep into her, causing her body to arch, trying to meet its every thrust, desperate need, but Rainbow Dash couldn't stand it anymore of this, she was ready to cum.

She was being bred. Soon she would be a female dog. Rainbow watched, hypnotized, helpless and horny.

The big Rottweiler fucked her hard, its large white balls slapping against Rainbow Dash's clit over and over again.

She felt cum draining from her pussy, she knew she was done.

She closed her eyes, not wanting to see what was about to happen, but the sensations were too much.

Rainbow was still cumming, and she kept on cumming, her legs shaking uncontrollably.

While her pussy was being penetrated by this beast, Rainbow let out a deep moan of pleasure, her head falling down. Once again, she felt the intense heat in her loins, and just as it did the heat began to subside. The Rottweiler continued to fuck away at Rainbow Dash's pussy, the huge hound of pain and pleasure having given her more pussy than she would ever know in her life.

Suddenly the Dash started to cum.

Rainbow yelped with the first wave of pleasure, before the sensation returned through her body as the dog's penis plunged down inside of her. In and out it pulsed in and out of her. Finally its large thick cock was buried deep inside her. Master continued to laugh as he watched Rainbow's pussy clench around the dog's enormous shaft.

It was so great, and she kept cuming just from it. It sent her over the edge again, and the dog's cock started to pump her full of cum. It flooded her, soaking her pussy, making her squirt all over herself, the dog jerking off. The dog just let cum fill her, spraying it deep into her hole. Rainbow could feel her pussy getting stretched and filling with dog cum, making her cum a third time before Master finally gave the order. Rainbow slowly came down off the dog; she was too hot to stand. With a long pant, she collapsed back onto the floor.

"It feels so gooood" she whispered in a low moans.

"You look like a filthy bitch now," said Master, slapping Rainbow's cheek.

"Arf! Arf! Arf!" barked Rainbow. Rainbow's eyes rolled into the back of her head as her body shuddered, her legs trembling as she was unable to move. Her pussy convulsed and sprayed Rainbow with the mixture of her juices in thick ropes throughout her vagina. Her mind became blank as she watched her lover get filled, filling her belly and filling her womb, filling her walls with its seed.

Her heat returned to its normal state, all thoughts were consumed by the hot and very horny Rottweiler.

The big black dog lay on her, as Master began to pet her. Master stroked her head gently while she licked his hoof.

It was going to be her new mate. No wonder she liked it so much. This was so much better than having to stay in heat all day. It was going to be the best in her life. In her dreams she was already pregnant from a Rottweiler and gave birth to its puppies. It is possible, right?
