Sadie and Serena's Fall - Part 06

Previous part

The following is a 300+ pages illustrated story. all characters are over the age of 18, and the story surrounds two step-sisters that are not of actual blood connection. The story contains several dark parts and has different horror and violent aspects to it. None of which is for the purpose of cheap snuff, but rather, to depict the cruelty and merciless nature of the underground world of debauchery. The world is a fictional one, and it does not share our world's history or development.

"Hands down. Don't cover yourself!" He barked at her.

Serena lowered her head in response. 

There was no alternative for her anymore. She was trapped. The only way to get out of this with most of herself undamaged would be to follow the voice, to heed the stranger in her dream.

Her thoughts went to the voice from earlier. She couldn't quite put a face to the voice. It was all hard to recall, but it stuck with her. The stressful and horrible situation she found herself in, the voice offered to relieve some of the burden by Serena relinquishing some control. 

The voice, the simplicity. 

It was very much against who she was, who she is. To lower her head and let someone decide for her. But the memory of the voice, there was an iota of solace in following orders. The least horrible choice was the one where she subjugated herself to someone else deciding. Control taken from her. In this horrible situation, it wasn't the worst that could happen. She withdrew the claim to any responsibility for what was to come. It was, in a sense, liberating.

This, however, was only a small part of how she felt. The disgust for the man, hatred of herself and the fact that she let this get to this point. These were things that burned stronger than the voice from the dream. But it needn't remain a small part of her mentality going forward. Allowing herself to give up even more control, to let whatever happens, happen... It would ease the burden... Surely...

Serena stood still. It was the hardest she ever had to fight to not move.

"Mmmh.. Good kitty. Good kitty." The man said, trying to calm her fire. 

"Lift your head, so I may attach my leash to your slave collar."

With those words, Serena couldn't hold back the tears. Still stifling her sobs, the tears began trickling down. She lifted her head slowly, and their eyes met.

"I will not hurt you, as long as you do as I say, you will be protected and looked after. You are precious to me. You may not understand, even if you most likely hate me, you will come to understand a simple fact..." He paused.

The tears stopped, her sobs were quelled. Mesmerized by his words, she waited in anticipation for him to continue.

"I must take the plunge..." She muttered to herself. Like a voice in her head suddenly took control."

The man gave her a nod.

"Yes, good. Throw it away. Throw it all away." 

She couldn't help but keep staring into his eyes. The disgusting and horrifyingly creepy man was speaking to her soul. Like the question that was hiding itself from her was suddenly answered. 

Like a helpless soul staring into greater purpose, she couldn't avert her eyes. A new warmth, weak, but still, very noticeable, began burning inside of her. Feeding to the fire, the eyes of the man had this commandeering strength. His physique was that of a sick, emaciated homeless person, but his eyes reflected something more...

The disgusting man was comforting her. 

He lifted a hand to her, she flinched, but as the hand met with her face, it was a warm and kind gesture.

He wiped a tear from her red face, then had her rest her face into his palm. He held her and slowly stroked red cheek. Gently. 

She couldn't stop staring into his eyes. 

She was so vulnerable, especially to this man. He could, if he wanted to, take her in one single motion. She was exposed and defenseless. His member had grown a little. Seeing a cute girl cry was always an aphrodisiac to him. 

"Ready for me to leash you?" He asked in a strangely affectionate way.

Serena nodded weakly, as her cheek didn't want to leave the warm touch of his hand. 

The voice in her mind was calming her. Inaudible encouragement and assurance. She felt comfortable in her choice to let him lead her. 

She wasn't left much of a choice, but it was a choice nonetheless. 

Was it the right answer to give herself to this man so easily?

The sound was deafeningly loud. The metallic clang echoed in her mind. The vibration of the metal snapping on sent tremors through her bones.

She stood still, not moving, barely breathing. 

He never let go of her while affixing the lead.

Serena felt so helpless. Clinging to the fact that she chose this, it made it all bearable. 

"Your eyes are so beautiful when the flame is extinguished. Be good, and I will treat you, I will protect you." 

She couldn't speak. The bizarre reality was so foreign to her. She didn't even feel like she was the same person. She had told her friends, proudly, that she considered herself somewhat of a feminist. Never to take orders from a man, never ever. Skip forward to the present day. She is allowing herself to be an unattractive man's pet for 30 minutes. Scared and crying like a little school-girl, she presents herself to the man as a little child that can't fend for itself.

"Your skin is impeccable. I've never felt such beauty in the texture of a girl's face before. Perfection in complexion."

She sniffled as her runny nose started to show.

"Rhinorrhea is the medical term for when your nose is running like this. Tears are pushing some of its liquid into your nasolacrimal duct, and through your nasal cavities, they mix with your mucus, and cause more to be produced, and the nose starts dripping. I'm not sure why it's not black liquid running from your nose, but I'm not a scientist. They seem to know what they're doing." The man kept going. Serena couldn't do anything but stare. The mix of emotions, her mind couldn't take in everything he said. 

I can... I can choose... I can learn... I can climb out of here... I will learn and show off my medical knowledge. I can be more...

Serena was a nurse, she was sharp, she was naturally curious, and she was also very stubborn. She was certain she would survive this place. The only thing that she was uncertain about was if she could save all of what she was, or if she would have to sacrifice parts of herself to make it out.

He was kind to Serena. Wiping her tears, and giving her a few moments to prepare herself. 

Whenever she was following him, the boots weren't that bad. It was when she didn't know what to do that balancing was nearly impossible. 

They entered the elevator. The doors were closing, slowly.

Serena began to sway, struggling to maintain balance. The man rested a hand on her hip, supporting and steadying her. She felt so exposed. The hand that rested on her, it felt like he was groping her naked body. 

Surrounded by steel and pulsating lights, the elevator rode them up in silence. 

The closer they got to the top, the more scared she grew. Afraid of what might await her, she leaned, ever so slightly, towards the naked man. She felt protected by his promise, and the deal they struck.

The elevator came to a halt. Her heart began racing.

"It's fine, little kitty. You're safe with me." He said as he pulled her in closer.

"Come now, kitty. You need to move your butt if we're to make it in time." The man pulled on her leash as she wobbled forward at an uneven pace.

Solely focused on staying on her feet, Serena was led along an abandoned road. Empty houses seen on the horizon. She already knew that there would be no help to be found here. But she never wanted to put her hopes on the help of strangers. The only way she would get out of here intact would be through her own effort.

She hadn't been outside in quite some time. There was something different. She didn't pay it much attention until it crashed against her.

A rather strong gust of wind graced her. The moment the air current blew past her exposed nether region, it wracked her body. 

Her knees were about to fail her, as she experienced a powerful orgasm brought on by nothing but a moderate breeze.

Serena fell over, the fall didn't hurt at all, but it was only the physical pain that was muted. It stung her deep, the way she must've looked, flailing on the ground. 

"Need help to stand up, little kitty?" The man looked at her the same way one would look at a child who'd fallen over.

Serena snarled as a response, but the growling scowl quickly turned to a shivering frown. Trying to stay strong, she slowly sat up. 

Another breeze came by. She shuddered involuntarily.

As she sat there, she noticed how out of shape she was. Not that it looked that way, but she felt tired from just walking a little. 

He tugged at her leash, pulling her chest a little closer to where he was standing. 

"Now, we are going for a 30 minutes walk. It has been 12 minutes of walking. I am not counting resting and falling. You can sit for as long as you want. "

Serena rolled her eyes. But before she could do anything else, she felt the cold and hard surface of her heel briefly tap her labia. She fell backwards as she started panting. Cheeks were already blushing more and more. Her body was betraying her. And in front of this man, too. 

Every time she tried to gain momentum to stand up, the heel she was sitting on would come dangerously close to her private parts. The insanely sensitive area was preventing her from making any progress. Her fatigue stopped her from experimenting with different methods of standing up. 

"I ask again... Need help standing up, my little kitty?" His tone was helpful, but calling her 'little kitty' did nothing but anger Serena. 

She tried several times to stand up. Making less progress each time.

The situation felt so hopeless. She couldn't linger here for too much longer, she wanted to get this over with. 

"Yes.. Please... Help me up..." She asked in a breathy tone.

"For you to stand up, you need to control the way you react when anything comes into contact with your pussy. After your treatment, I suppose the sensitivity has been boosted. And it seems that it builds up if left unchecked. Builds up to a point where you lose all your ability to move. Want me to help you recover your footing before helping you up?"

Serena couldn't quite follow everything he said, the words kept flying at her, but she was so busy trying to maintain a certain level of respectable facade. 

"Yes... Help me..." She uttered when he stopped talking. 

"Good kitty. Asking me for help is a sign of trust." He said in a satisfied and warm tone.

The man knelt down next to Serena and grabbed her tail. He massaged the end of it with one hand, and within a few moments, Serena was panting and moaning. Unable to contain herself, she tumbled backwards awkwardly. The man slowly moved closer, grabbing her left thigh and digging in. Slowly making his way towards her moist and starving sex.

As she turned to mush in his hands, he pressed on. Slowly positioning himself, angling his own manhood towards her unprotected opening. 

Serena couldn't do much in response. The pleasure that she derived from this man's touch was out of this world. Her tail was so sensitive, him massaging it was enough to send her over the edge. 

But, again, it wasn't enough. She climaxed, yelling out, spit and pleasure erupting from her mouth, her legs shaking, and her wet focal point pleading for attention.

"Can I fuck you, little kitty?" He asked through gritted teeth. 

"Aaah!" Serena screamed out as another wave wracked her.

"Let me fuck you!" He said, shaking in anticipation, his phallus inches away from her wet and self-lubricated opening.

Serena slowly opened her eyes. Her chest heaved as she gathered enough of her fragmented consciousness to see straight. She saw her self-proclaimed owner drooling at her, his beady eyes locked onto hers. His left hand was grabbing her right hand, holding it down, his knees had pressed themselves between her own legs, forcing her own legs open. He had let go of her tail, but it kept brushing itself against the man's face. Stroking his old cheeks on its own accord.

The man was repulsive, but she had already moved past his looks. As she stared into his eyes, her lips quivered and her crotch thrust itself towards him in response to what he did next. 

Holding her head passionate with his right hand, he was rubbing her new ears. The sensation wasn't just sexual, as it had been with the tail, it felt so much more intimate. It was like the sweetest words trickled into her head. She couldn't help but move her head up and down in response to his cuddling.

In the heat of the moment, she managed to isolate another new sensation.

Something wet and warm touched her lower lips, her labia had just come into contact with a foreign object.

She stifled a moan, and it became a tiny yelp that she further tried to quell. All that came out was a startled purr.

The man's eyes got slightly watery as he just couldn't take this cute little thing without consent. It was a stupid thing that he never had subscribed to in the past, but this time. Even against his aged wisdom, he made an exception.

"Tell me that I can fuck you, give me permission to push my cock inside you."

His words weren't aggressive, but nearly pleading.

Serena looked at him, finally managing to regain some sense of self before saying in a breathy and weak tone.

"... no."

A lingering moment of hesitation, the man stared hungrily at her wet and twitching entrance. Ever so inviting, ever so beautiful. 

He moved to the side, shifting his hold on her. With the left hand, he cradled her head, stroking her new ear from the back with his index finger. With his right hand, he brought it down, down, down.

She was so warm down there, he could feel the heat in the air half an arm's length away from her crotch. 

He wanted to do it slowly, but she had already been prepared for intercourse. He plunged two fingers into her. The moment of penetration, her hips thrust forward in response. She moaned in ecstasy as the man worked her body like a fiddle.

There was a tenderness and love in the air, she wasn't totally against what was happening, she needed this. It was on her terms that he devoured her flesh, and that gave her strength. Just now she noticed that he had taken her leash off. An act of kindness that should be repaid. She pursed her lips. He caught on and met them with his own. Their mouths' wet union was not a kiss one would see in the movies. Saliva coated her lips and began to slowly trickle down. He kept massaging her ear while expertly giving her private area the ride of a lifetime. 

Serena was usually a one and down kind of girl. When she had reached the climax of the night, her body, feeling content, would immediately shut down. This could be rather frustrating for her partners, but her attitude towards men, and how she wanted to be a progressive woman of equality, had made her a little selfish in bed. 

That being the case, this was a new experience. The climax had her nearly fainting, the explosion of undistilled pleasure saturating her body with a sexual glow that refused to be quelled.

She kissed the man with all she had. Rational thinking was long gone, at least, the calm and collected sort of thinking that would allow her to base her choices on long-term agency and fruitfulness. It was all an act of impulsiveness and passion. She felt like herself, to some degree, she still retained her pride, she still could say no, but it was a good state of mind she found herself in. Good as in she was feeling great, and still had most of her inhibitions. Not like a night of overindulgence of wine and champagne. The one where she would regret everything she could recall the morning after. 

She moaned in rhythm with the locomotive motion of his right hand. A cute and light sound that she had no control over. He could gauge her level of arousal, and how close she was to climaxing by the sound she was making. As he neared the finale, he disengaged the kiss and whispered to Serena, "You will come for me, little kitty. And you will moan as you do. In 3...2....1..."

As if following his direct instructions, an explosion of emotion and pleasure engulfed her body. 

This was nothing like what she had felt earlier. Her high pitched scream could be heard from miles away. She let it all out. Her body hadn't been able to satiate its thirst for sexual stimulation in quite some time. But now, it is finally happening. An orgasm that had been building up for weeks. 

The bright skies of above vibrated, black dots of screaming nothingness began dominating her view. A hood of streaming colors were pulled over her head. Light became dark, and dark became all. She kept shaking as her body still wasn't done climaxing. Even as she lost consciousness, the pleasure wasn't done with her.

Serena returned to her senses. It felt like a burden had been lifted off of her body. She felt stronger and better than ever. But even more than that, she felt so cozy and at peace.

The man was sitting there, with her head resting on his lap. 

He hadn't taken advantage of her while she was knocked out. She could remember everything up to the point of when she passed out. 

She just lied there for a few minutes. Thinking back to what they'd done. 

She didn't really feel that embarrassed. She might be sporting an invisible panty, but he was completely naked. In some weird way, that thought comforted her.

Slowly, she crawled up further in his lap. It felt amazing. The rush of emotions had taken down her guard. She felt vulnerable, but in his lap, it didn't feel like that bad of a thing.

He finally spoke to her.

"You did so well, kitty. You should be proud." His words were so soothing and pleasing.

"You deserve some aftercare." 

He hoisted her up a little before kissing her forehead and praising her body with his hands.

Her tail curled up, her eyes swelled a little with tears from pure happiness. 

He trailed his thumb across her lips. She pursed them and let the thumb play a little with her mouth. She playfully nibbled on it, then caressed it with a gentle stroke of her tongue.

Her cheeks were warm and red, her state of mind was one of pure bliss and tranquility. 

"Moments of intimacy between the two of us should be treasured and rewarded..." He kissed her forehead a few more times.

"Your body is deserving of reverence. My hands praise it through contact."

His hand was firmly placed on her left breast. It gently squeezed it in rhythm with her breathing.

"You will be rewarded for good behaviour. Trust in me, let me guide you. I am here for you when everyone else disappears."

Serena was jelly in his hands. This disgusting monster had moved into her heart. All he needed was a finger, and he took the whole body and soul.

This state that she was in, this afterglow, it would always trigger after deep intimacy. She was, without knowing it, easily programmable when in this state.

He didn't want to spend all day outside, so after an hour of intimacy, he signaled Serena to move.

As he got up, he dusted himself off.

"You must've been a cat in a former life, for you are just amazing." He complimented her.

Serena looked at him with a smile and a raised eyebrow.

"We will continue the walk now. You should be in good shape now that you've been freed from the heavy weight that was holding you down."

Serena nodded slowly. She did feel great, but she was kind of tired, mentally, from today. Being pulled by the leash on the impossible heels, it wasn't tempting.

"Or..." He added.

Serena perked her ears and tilted her head.

"Or, we could just take a walk tomorrow, and you can walk at your own pace back to the complex without being led by me. I can help you with balancing if you want."

"I..." Serena began, a little unsure of what to respond.

"I can do the walk tomorrow instead. Thank you." She responded in an unusually shy tone.

He reached a hand out to her as he bent down a little. First reaching for the ring on her neck, but then stopping at her chin, lifting it up. He supported her head as the two locked eyes.

"If that is what you want, then I shall grant it to you. For the walk back, I will answer all questions about the things they've done to your body, of course, to the best of my knowledge. I may choose to not disclose certain things, but I will grant you this unique opportunity to get to know your new body a little more."

Serena had mixed emotions. He would satisfy her curiosity, something she burned for, but he called it 'her new body' which made her shiver a little. 

"You shouldn't worry yourself too much about these things, sometimes knowledge can be a burden. I heard that you're quite the capable nurse, so you must know something about the topics we could discuss. "

She smiled, acknowledging her based on more than looking like a cat was a great feeling that warmed her heart. Although she didn't mind being showered in honest compliments.

He chuckled a little.

"That's more like it. A happy kitty is a good kitty." His tone was playful and warm.

Serena giggled as she lifted her arms like a pet. It was a playful gesture, only meant for a good chuckle. Her owner didn't chuckle at this. He Leaned forward with a glowing smile.

"You are amazing." He whispered to her. It felt so honest, she felt both proud, and a little sad that she did it as a joke. So as a small consolation, she held her arms in that position for another minute.

He ruffled her hair and gave her a kiss on the cheek.

Serena and her owner walked back together. Not wanting to try and walk properly in heels, she just leaned on the man walking next to her. He didn't mind.

Their conversation was mostly about what she knew within the field of medicine. He actually told her about his skin condition. Staying out in the sun for too long wasn't good for him. A normal person with his condition would be dead by the age of 5, but he came from money which allowed him to live with the condition. 

She had yet to ask for his name. As they walked, she wanted to ask this, but there was something gnawing on her. Like she had forgotten something. 

Was it that she was supposed to detest this man? Was it the fact that she was clad in a porno outfit, and made to wear stripper heels that she couldn't walk in?

She got quiet as she rummaged her mind for answers. The man noticed her frozen facade. His timing window was closing, and it was just in time.

"Look at yourself, deaf, mute, blind bitch. You're not even stopping me when I'm choking you. Maybe I should just end your pathetic life right now." 

Moans and wheezes echoed from the walls as the brutal man defiled her body with maximum violence. He slapped her fat ass and strangled her. She was his plaything, and she was moaning and drooling like a worthless whore. 

"Drink up, pig!" He cleared his throat, before sending a thick blob of spit down her hungry mouth. 

As he got wilder and wilder, he nearly jumped on her for every thrust. His large manhood plunging deep into her each time, her fat udders bouncing each time.

Sadie was played with like a toy. The man had actually picked her up, while ravaging her, and carried her to a new location. She had no idea. She had nothing left. It was only pleasure, nothing else. How long had it been since a rational thought had filled that empty head?

"I can't wait to get you trained for your next, and most likely, last assignment. I can't wait to see your soul break." He kept talking to his plaything, fully aware that she couldn't understand.

As he walked, he made sure to bounce her roughly up and down. Twisting her arms, forcing her shoulders back, he showed her no love or sympathy.

"What am I..." The surgeon began. A voice from behind, slightly tired from doing Sadie for 2 hours straight. 

"Look, the boss said that you're to take 'em out. And if you do it while doing her, you get triple pay, and you get to use her for an hour later on as well."

"Heh... Such a useless slut. When you have to bribe people to actually stick their dick in her. But all right. I'd love to try, but I'm not being held responsible if something goes wrong, right?"

"Yeah, that's implied. You'll be humping her while performing surgery after all."

The two started laughing. 

Sadie just followed instructions. The weird plastic-gloved man was positioning her on a small platform. Then showed her how to hold her arms. She then howled out in lustful bliss as an unusually thick phallus inserted itself into her. She got the idea that she was to hold this pose while they were using her. 

Wanting to please and impress, she did her utmost to maintain a good pose.

A slight sting on her lips, and suddenly she couldn't feel her mouth anymore. But regardless, she tried keeping it gaping.

Something was scratching and vibrating in her mouth. She had no idea what they were doing, but maybe they were helping her. Her thoughts never lingered. She had taken refuge deep inside of her own mind.

An hour went by like this. She was turned into an object, and then proceeded to be sculpted and fucked at the same time. The level of demeaning and dehumanization that was going on had her climaxing constantly. The hour went by in a blur of ecstasy and pleasure. 

What they were doing to her was not going to be to her benefit whatsoever...

"What... the fuck?" The surgeon said to the other man.

"Why is... Why am I getting readings like these?"

"What's going on? The man who brought her asked.

"She's been implanted with a lot of stuff, but for some reason, everything seems to be turned on. It's turned on, but the light on her chest isn't lighting up. Did you guys never check if she was turned on?"

They spoke briefly before the surgeon returned to Sadie.

"Ok, so. I'll finish up this project, get paid, use her a bit more, then we'll tell Murtak. He will not be happy to hear. I recall him rambling on that he was given a worthless whore when he asked for someone to train. This explains... A lot..."

The surgeon said while continuing to fuck the brains out of the unknowing creature.

"You sure we should wait? I mean, this is kind of..." The other guy started, but was quickly interrupted.

"I want my pay and I want what's promised to me. You've already played with this fucktoy to your heart's desire, but I want more. I've done shit work for shit pay. About time I got some to enjoy myself." The surgeon said in a stubborn voice.

"Just 'cuz you spend all your cash modifying your own junk doesn't mean..." The other guy said under his breath, but was quickly told to leave. 

It was just Sadie and the Surgeon. Sounds of metal and copulation filled the room.

He had taken her teeth.

Using not just science, the operation wasn't very hard, nor was it time-demanding. He just worked slowly so that he got to ravage this tender flesh.

"Look at yourself. A perfect fleshlight. I added a little extra springiness to your lips, why not, hehe. Aren't you happy? Aren't you happy that I've taken away something so precious to you? It turns out you weren't broken, but just left turned on for weeks. So, you should in theory be clear enough to actually function. To climb the ladders of this weird social structure that you slaves will be dropped into. But not now. I mean, look at yourself, Sadie. Sadie Louis, the pig sex toy. But unlike sex toys, you self clean... Mostly." The surgeon took pleasure in knowing that he was ruining the life of this girl. 

He pulled her lips to the side, checking the inside of her mouth. The plump gums had already become soft and solid pads that would only stimulate whatever penis they were servicing. 

"So tempting to permanently ruin your other senses, but I guess your owner wants them this way so he can remove the implements later." He slapped her face, the force left her head turned to the side. A soft gurgling moan following his abuse.

"Stupid fucking pig, it's almost boring to beat you if you enjoy it."

In a series of strong pelvic thrusts, he pushed himself deeper and deeper inside of Sadie. Smacking her breasts, spitting on her face, slapping her ass, body, and face. As he was choking her, he shot his hip forward, injecting his seed deep inside of her. While doing so, he grabbed her ass and pulled her towards him. Holding his abusive member deep inside of Sadie as it deposited load after load of cum. 

"Get pregnant, dumb whore! It's the only thing you're useful for now!" 

As he pulled out, he pushed her off the little platform she was placed on. As she hit the floor, her head cushioned by her boobs, a spurt of white liquid shot out of her gaping sex.

He wasn't done with her. Walking over to her, he took a sip of a little vial. His refractory period reset, and he was ready to go again.

"I want to sample your upgraded mouth-pussy. I was promised an hour, and I will enjoy it."

Pushing her down to her knees, he bent her over and planted his cock deep inside of her throat. His legs and hands all held her in place as he pleasured himself with her toothless mouth.

"Fuck... This is how a female's mouth should be!" He grunted as the intense feeling from Sadie's whole mouth rubbing itself around his phallus pushed him to greater heights of raw pleasure.

Her gagging sounds filled the room as her nose denied any air through. The gurgling mess that was Sadie became sloppier and louder as she felt the lack of air slowly sap her of strength. 

He didn't want her passing out just yet, so he smacked her face repeatedly and started working her body over as well. He was hunched forward, raining down slaps, as he kept pistoning in and out of her mouth. 

Pausing, giving her a moment to catch her breath, he let her cough and wriggle around for a few seconds before resuming his intense fucking of her little throat.

Page 223

Sadie's body was painted with the abuse that it had weathered under the ruthless domination of the deranged doctor. 

He had his fun with her, now he had a final task to do. It was a simple one, and not very exciting.

Inserting a big fleshy phallus into Sadie's hungry hole. Once inserted, it spread inside of her. Filling out her hole, venturing deeper inside of her. Connecting to her neural network through micro-spurs that dug into her. Within moments, she could feel every part of this large, wobbly, and clumsy sex toy. It was an older version of what her step-sister had, and this one was temporary. It came with both synthetic muscle fibers, and an energy cell. Unlike the newer versions, this couldn't use the energy of what it was attached to. 

As he gave it a tuck, Sadie let out an animalistic moan. Her mannerism had degraded during their encounter. She never moved unless pushed or pulled. The only movement she engaged in by her own volition was the gyration of her hips, the thrusting and squatting. Every part of the sexual activity she was used in, she instinctively moved in rhythm to. Anything else she didn't even respond to anymore.

"Perfect. And just to make this more interesting..." He took a syringe and injected its content into Sadie's labia.

Sadie's legs began shaking, she started rocking back and forth while making pig-like oinking sounds. She was revving up, getting a surge of energy, and a desperate lust that needed to be quenched.

She was then led into a new maze of corridors.

Page 224

A door opened without making a sound, a man then slowly pushed Sadie into a new room.

Sadie walked forward. She was desperate for something to satisfy her new cravings. It was eating her up inside. It ate away at her, and it was such a terrible sensation. She started jogging forward while holding her arms out. She felt something, not too far away from her. A target. With her new installment, her new task must've been to devour something, the same way she's been devoured.

Charging at the only light of her life, her one source of true inspiration and hope. She was about to assault her own step-sister. 

Serena was so busy looking at her own tail. She could make it move, but it was difficult. It responded to her on a subconscious level, but she could trigger some feelings to make it move. 

If she was thinking about the wind caressing her groin, the tail would lift itself and move to the side, if her thoughts started thinking of the dread of where she was, it would curl up, reaching under her legs and coming up to her front, almost like it was scared and wanted to hug her. 

It wasn't ideal, but she also noticed that, if she was about to lose balance, it would instinctively shoot out and try to act as a counterweight to help stabilize her. That's why, when she wasn't thinking about it, walking in heels wasn't nearly as hard. And why, the moment she tried and made an active effort to balance, the new weight of the tail threw her off, making balancing nearly impossible. 

She had made such progress. Finding ways to occupy her mind to avoid the mental strain she would suffer if this place got to her. She understood the voice now. She knew what it meant. It was a way for her to survive. Throwing away her stubbornness, allowing herself to be led. It was an act, but that was only something that she realized would be indistinguishable from actual behavior patterns over time. Afraid that this might come to leave a permanent mark on her, she felt the nervousness and unease come over her again. Her tail came crawling up her crotch and she began petting it. It felt strange, but somewhat relieving. Her thoughts returned to the tail, and the functionality of it. She had finally received answers regarding how it was connected to her. Intelligent matter that possessed the ability to change, as long as it was given enough power. As it was operated into her spine, it carried a strong enough charge to transform its connective end into a million tiny strands that connected to her neural network. As it did, it could collect energy in the form of tiny electrical impulses that traveled through her spine. As she used it more, the nodes leading energy to her tail would evolve, allowing for more and more energy to be harnessed by it. At this point, it must be fully integrated. 

She found this information incredibly fascinating. She wouldn't have believed this to even exist prior to her being given a piece of it. 

An alloy combined with something called 'unliving steel', why has this not revolutionized the medical field? Why have I never heard of it before today?

She wouldn't have time to think more on this matter as a beast in pink was about to attack her.

Sadie tackled her step-sister into the ground. She could feel the femininity even before touching the person in front of her. It was a girl in a plastic suit. She only had a hood. This one must be much lower than even her to have so much more plastic on her. 

With that in mind, she grabbed the trampled girl's arms, locked them behind her back, then shoved her down into the ground, grabbing her legs, and with very few steps, began pistoning into her with no kindness or warmth.

The sensation of sexually assaulting this poor, innocent, unknowing, and helpless girl was fuel to the fire within her. 

Bruised and battered, Sadie's body was hurting all over, but it was all put aside. It was all about satisfying her unhinged lust. She was a beast.

"Stop it, STOP!" The girl screamed at Sadie, but to no effect. It landed on deaf ears. She started crying. Yelling, screaming, thrashing, bucking. No effect. Her mittened fists rendered all her attempts futile. The savage strength of the girl tearing into her was also on another level. 

Sadie was fueled by drugs and adrenaline. She couldn't stop herself, she was pure carnal instinct, and nothing else.

Serena then saw something that made her heart shatter into a million pieces.

She recognized the circular metallic object lodged into the chest of this busty girl. The huge boobs, the small details in the skin, the sweat and smooth skin...

"No..." She uttered as she stopped resisting. Giving up as her own step-sister raped her. Betrayed, she lied there, her body bouncing in rhythm to that of her own kin assaulting her. 

Sadie noticed the lack of resistance, and took this moment to slap the girl's face and boobs, just as they had treated her, she smacked the helpless girl. The nightmaric climax of their journey.

The world couldn't possibly have worse things in store for them...

Sadie was devouring her step-sister with no remorse. 

She pushed her to the side, as she kept pistoning into her, the sobbing mess that was Serena could do nothing but cry out in vain.

Sadie licked Serena's face, it was wet from crying. The taste was so strong and salty, she kept coating her face in more drool as she lapped her tears, drinking it like a beverage.

Wanting more and more, she attached her mouth onto Serena's nose, sucking at it, the vacuum dragging all the snot, saliva, and tears from the nose and sinus. She kept sucking her face, while her hips never relented from defiling her sore pussy.

Serena looked on in horror as her step-sister's tongue wiped her face around the nose, hungrily taking in all of her tears. The slobbering monster that once was her soulmate, now a soulless monster stabbing at her heart.

Not done with her step-sister yet, Sadie needed more. She pushed her over, wrapped her legs around Serena's head, and pushed the entirety of her new phallus inside her mouth. Struggling to squeeze the whole new object into the small throat, Sadie used her new-found brutish strength to savagely shove the last few inches of the giant gummy-like monster inside the gaping mouth.

As it clogged her throat completely, Serena couldn't breathe, nor could she move her neck. Filling her to a point of nearly rupturing her esophagus.

Her useless mittens rubbing against the thick thighs, hopelessly flailing and thrashing. 

Panic giving her a second wind, before defeat slowly sapped her of any strength to resist. 

The spasming death throes of her step-sister along with the tight throat, it brought her to another mind-numbing climax. Sadie started licking Serena's exposed hole, hungrily exploring her labia while the girl she violated started shaking. Everything turned black, as Serena welcomed the sweet nothingness of unconsciousness and that which followed.

Tightly wrapped around Serena's body, Sadie was latched on, like a parasite.

Wanting more of her sweet nectar, she helped herself to some as she lapped away. 

Killing her kin while defiling her soul. Sadie wasn't aware of what she was doing.

This tastes familiar...

From nowhere, a coherent thought entered her mind. Echoing, amplifying itself.

The thought became a call, the call became a scream, the scream shook her to her senses. 

"Shifter..." She blurted out as she pushed the ass of the limp body away.

She flipped around and backed away from her step-sister, who, still attached via the mouth, slid along the floor, being dragged after Sadie.

Sadie desperately pushed Serena's head away. Slowly, inch by inch, her phallus was pulled out from her abused throat.

She was kneeling next to Serena's still body. Shaking, she shook the torso of her step-sister. 

"Sish..." She cried out.

"Wake up..."

"S... Sis..." Sadie's heart fell, she felt like dying. 

...

Serena's body moved, Sadie jumped back.

Serena coughed and cried, crawling away from her deranged step-sister. 

Taking big gasps, she felt a wave of adrenaline course through her as she heaved, gasping for air. 

Shivering as flashes from what happened played out inside her mind. 

She felt sick, her head throbbed painfully, she screamed out as she curled up, rocking back and forth while letting her pain out. 

Wanting to die, she started knocking her head against the floor. She wanted it all to end.

Sadie felt the vibrations through the floor, she could feel the pain, it was unmistakable. Her step-sister was in pain, and she was the sole cause of it. 

Sadie couldn't move her body anymore. She was hugging her own legs, trying to speak, trying to explain herself. Her lips moved, but she knew she didn't say a word. Spit dripped out of her mouth as her lips were trembling, never to find a single word to utter.

Shouting strange words at Sadie, Serena's owner came storming into the room. 

Just noticing what had happened, he rushed over to Serena. 

Sadie felt electricity jolt through her body. A burst of power that overwhelmed her. Within a second, she fell backwards, unconscious.

The man lifted his little kitty with care, making sure she was still conscious.

As he lifted her off the ground, Sadie hit the cold floor.

He lifted Serena out of there with haste. He had to prepare a potion quickly. The physical damage wasn't that severe, but there might've been some brain damage that needed some quick mending, but even more important was the psychological damage. If that went untreated for even minutes, then it would manifest and strike roots deep into her soul.

Sadie wasn't left there for long. Not long after, her master came and carried her away.
