The Perfect Pet

The compound was silent. White Mask terrorists lay sleeping, a token few left on guard, lazing in the prison cells, only passing attention paid to the gently pulsing monitors that assured them all was well. A car slowly rolled up to the building and was waving in by a guard at the gate, windows blacked out it was impossible to tell the contents of the vehicle.

Locked in a cage, unable to sleep on the cold stone floor lay a naked Eliza Cohen, member of FBI SWAT, where she had picked up the nickname Ash, in reference to the debris she left in her wake. More recently she had been recruited as an active member of the reactivated Team Rainbow, a secretive, all female task force, now under the leadership of the mysterious Six.

It was Team Rainbow she was now relying on to break her free, the mission on which she had been captured was deep undercover, she could count the number of people aware of her objective on the finger of one hand, even her captors, the terrorist organisation known as the White Mask's had no idea they had a world renowned counter terrorist on their hands, she had considered telling them her true identity in the hope of being ransomed, but even if they believed her they would more likely kill her, given her involvement in the downfall of their previous plans.

Shivering, she rolled over to her other side, her tits pressed against the cold floor, sapping her warmth and her resolve, hugging her arms around herself in a futile attempt to heat her body up. She had been so close to finding out the secrets behind their latest weapon, some kind of mind altering substance only known by the codename KinKi, going as far to be recruited into the White Mask, establishing herself as a valuable and loyal member, only to wake up one day in this cold cell.

She sat up and walked over to the bars of the cell, from which she could see the monitors displaying cameras around the compound. Out from the car parked out front she saw a man dressed in a white coat, carrying a briefcase, striding towards a prison block. The guard sitting at the desk saw her watching and walked over to her.

"What're you looking at slut? You feeling chilly? Maybe you want a real man to come warm you up, you need an injection of my hot meat, stat." He laughed and grabbed his crotch, running his eyes over the girls' bare body, taking in her perky tits and erect nipples, her coppery orange hair which still was tied back in a ponytail, down to her shaved pink pussy. He was clearly erect, rubbing his cock through his uniform.

"You'd better slow down there fella, before you shoot too quick." Ash winked and turned, hiding her fears and embarrassment behind a façade of confidence. "You look like the sort who does." Turning herself around showed off her sleek ass cheeks to him, jiggling only slightly, her athleticism clear to see.

"You little cunt!" The guard shouted and made a grab for her, but she was already out of reach, lying down again facing away from her enraged captor. "You're in for it now bitch, I'll…" He was cut off abruptly by the door swinging open. The man in the lab coat walked in, weighing up the situation, flanked by two men in black suits and sunglasses, despite the darkness outside. One carried a large duffel bag, contents unknown.

"Leave us." His voice was cold and calculated, and even the furious and horny guard saw that disobedience was not an option, adjusting his trousers and walking away muttering under his breath. "Now…Liz is it? No need to be afraid. My name is Doctor Tuls. You were chosen for your dedication to the cause, I'm afraid this rough treatment was because previous subjects chosen were…unwilling. I'm sure we will find you…" His guards simultaneously moved their clothing to display guns hanging from their waists. "More compliant. Now don't move, all we need to do is give you a little injection and testing can begin."

Ash's mind was racing, desperately searching for a way out, but each option ended with a bullet in her brain. She found her mind settling on the case that Doctor Tuls was opening, marked with a KK. KK…KinkKi? Could this be the mind control substance she was sent to find? Seeing no other option and steeling her mind to fight the coming mental battle, she allowed the men to enter and seat her in a desk chair brought into her cell. Taking a deep breath, she let the scientist remove a syringe tipped with a long needle from the case and slide it into her arm. Once all the serum had entered her body he stepped back and watched her.

Dr Tuls rummaged in his coat, bringing out a recording device. Into it he spoke "One minute since injection, subject seems normal, no signs of emerging fetishism." He smiled at Ash and explained "The serum acts on your innermost desires and thoughts and brings them to the surface. It's so powerful that it can remodel a human body, other subjects have found their…assets enlarged, some found a desire to be so powerful they could not function without indulging it. I wonder what it will be for you, I must say, the surprise is really the most fun part." At this he laughed and spoke again into his recording device "Three minutes since injection, subject seems to be feeling hot, squirming in her seat, almost…panting."

It was true. Ash couldn't keep her tongue in her mouth, the heat was pulsing in her vagina, making it drip its sweet juices over the chair. Visions were forming in her head, the family dog, so happy, so fun, so playful. She wanted to be happy too, she wanted to be a happy girl…a happy puppy.

"What… what is this? What did you…AH! Do?" Even as she tried to resist, she felt herself slipping out of the chair, an absurd thought forming, pets weren't allowed on furniture. She looked down to collect herself, then stood up. Up. She couldn't. It was only slightly alarming that she couldn't rise any more than to all fours, crawling on her knees, her mind already being rewritten to that of a sexy playful puppy.

Dr Tuls was standing over her, having rummaged around in the duffel bag brought with him, and as she gathered the last of her resistance to reach up and fight him, she heard a click around her neck. A collar. The last of her fight went, her mind gone, replaced with the simple need to be a good pet.

"Ah yes, pet play. Surprisingly common. I wonder if you were particularly aggressive before eh? The violent women are usually the ones who need to be collared and tamed. But you're my good little puppy, aren't you?"

Ash found herself nodding for her Master, a smile growing on her face. She was a good puppy! That was all she needed, all she ever wanted. The lust in her pussy made sense now, she was in heat, she needed to serve her Master for relief. Her mouth hung open as she squatted in front of the scientist, begging him.

"Oh? Does my puppy want cock? Is she a little cumhungry whore?". He laughed at her frantic nodding and unbuckled his trousers, revealing his thick cock, easily 8 inches, hanging in front of Ash's drooling face.

She fell on it in an instant, slobbering away at his meat, swallowing it down her throat, slurping and licking up all the precum that marked her beautiful face, spit and precum running down her face onto her tits. With one hand she jacked him off into her mouth, with the other she was hungrily fingering her pussy, grool all over her fingers, rubbing her clit and moaning around the fat cock in her mouth.

"Good puppies make everyone happy, don't they?" Her Masters words pierced her thoughts, cutting through the cloud of cock worship. She was a good puppy, she should make everyone happy. It made sense.

The two suited men walked over to her, cocks hanging out and she whimpered with lust at the sight of them, begging with her eyes for permission to serve. At the nod of her Master, she began to suck and jerk them off alternately, slathering them with her saliva then using it as lube for her hand. So occupied with them was she that she almost forgot her Master, until he brought his hand down on her ass with a sharp THWACK, making her moan with pleasure.

"Puppies need a tail. Hold still pup". He caressed her pussy, gathering the wet juices that soaked her, and slowly slid a finger into her tight asshole, working it around until it was well lubricated. Popping his finger out he quickly replaced it with a tail plug, with a lovely red-haired doggy tail. She moaned with joy as it slid in, filling her ass nicely.

"Wag your tail puppy, wag for Master.". Ash waggled her ass back and forth, her cheeks rippling gently, as her Master reached down to her soaked pussy, her tail waving in the air behind her. He slid in his cock and began to fuck her, Ash's mind was on fire with lust, she couldn't hold on much longer, and began to moan loudly, almost whining as she was fucked into the ground, still jerking both cocks in her hand.

She felt her Master stiffen and release inside her, filling her insides with fresh cum, white and sticky. Content, she sat up and the two suited men released seconds apart from each other, covering her face and tits in creamy goop. She smiled and licked her cum covered lips. This was what she wanted. She wanted to be filled and sprayed with cum, she wanted to be a good pet for her Master.

Dr Tuls rose and did up his trousers. "You did well puppy." Bringing out his recording device he spoke "Test successful, subject fully broken, will relocate to secure facility soon". He packed up his kit and waked out of the cell, his two cronies in tow. A last look at the cum covered, plugged and broken Ash was enough to make his cock twitch again, but he had more work to do. He walked out of the door, motioning to the guard he previously told to get out.

"Don't tire her out too much". He winked and strode back to his car. The guard took a look inside the cell and did a double take. Ash smiled up at him, her breasts glazed with cum and a happy, content look on her face. The guard couldn't get his pants down fast enough, and Ash smiled the whole time. This was her life now, and as long as she got some headpats and a nice meal of cum served regularly, she was happy.

I'm planning to do all the operators, probably in order but if there's much demand for one I'm very open to listen. This was probably the most plot heavy chapter, most of the others will be more sex-centric but there will be an overarching plot not just a series of one-offs. Hope you enjoyed
