A note from Miranda Mackinder
This story has been originally written in Polish and translated to English by AI. Although I'm fluent in English, I'm not comfortable writing fiction in it, hence this solution. I hope the translation is smooth enough. Realizing AI translation is not a perfect solution, I'm looking for a Polish to English translator for my stories. If you're interested, please contact me! I'd welcome any reviews and suggestions, including ideas of how the story may develop in the thord part. Reader engagement will motivate me to write more.

I'm experimenting with turning my ideas into comic art in collaboration with a comic artist. Support me for any amount here: https://buymeacoffee.com/mirandamackinder to receive a surprise artwork and help me eventually turn the stories into full comics.


The syringe plunged into the purple buttock, administering the substance. Pati held the plunger embedded in the vein for a good while longer than necessary, savoring this new form of desecrating the victim. When she finally finished the operation, she didn't give a thought to dressing the injection site. Instead, she let a crimson trickle of blood flow calmly down Jacek's backside and leg.

The girls released Jacek from the straps and dumped him from the bed onto the dirty floor of the apartment. Pati prepared another tool taken from her backpack: a whip. They waited, giggling softly, knowing exactly what the next act of their diabolic spectacle would be.

A strange transformation began to shake Jacek's body—as if he were regaining strength in his muscles, moving slightly. But just as he thought he was regaining control over his body, his muscles failed him again, but this time swinging to the opposite extreme, where immobility would have been a trifle. To his utter horror, his entire body was seized by crushing spasms and convulsions. He began to writhe in total chaos across the floor, limbs tangling, bouncing on his stomach, tossing his head like a possessed man—all of it completely without the brakes of his conscious control.

Whack!

Pati struck him with a sudden overhead swing of the sharp whip along his back, leaving the first red stripe.

"Don't move, bitch!"

He obviously could not obey the command and remained in convulsions.

Whack!

As he twisted onto his back for a moment, the second strike of the whip cut across his chest.

"Stay still, bitch!"

In a continuous fit, he rolled onto his back again and writhed across the floor in a random direction.

Whack! Whack! Whack!

Three flexible, lightning-fast strikes of the whip cut across his legs.

"Don't move, bitch. I'll whip you until you calm down!"

He continued to writhe, unable by any force to stop the epilepsy induced by the injection. Pati fell into a truly Bacchic fury, lashing with the whip again and again, without pause, without reason, always with a swing, always putting the maximum strength she could muster into each blow:

Whack! Whack! Whack! Whack! Whack! Whack! Whack! Whack! Whack! Whack! Whack! Whack!

Meanwhile, Gabi wasn't idling. She sat down at Jacek's laptop and simply couldn't believe her good fortune. She got into the system without a password, and in an open browser tab, Jacek was logged into his email!

Pati and Gabi had plans for Jacek's future. Plans that no one should interfere with.

The matter of neighbors who might notice something was settled for the moment—in the terrace house, besides them and Jacek, only one family lived, and they were on vacation. Gabi had previously asked the father of that family, sweetly and ostensibly out of pure interest, how long they were going for, and received an answer that it was for a month. So they had plenty of time for now; they would think about how to handle that inconvenience later.

All contacts had to be checked. They had scouted him earlier and knew he was a loner with no contact with his family. They suspected that his only regular social contact, through which his sudden absence might cause interest or concern, was his work. He worked remotely as an IT specialist.

Indeed, a review of the mail seemed to confirm this. No important emails other than employment matters from the company.

"Pati, how are we doing this in the end?" Gabi asked. "Do we write a resignation for him, or do we let them fire him for absence?" They hadn't yet decided which method would provoke fewer questions.

Whack! Whack! Whack! Whack!

"Write a beautiful and professional resignation for the bitch," Pati answered without interrupting the whipping.

"It'll be a bit hard to focus with the whistle of the whip over my head," Gabi replied jokingly, "but priorities are priorities; our bitch must be trained in obedience."

So she sat and wrote the resignation to Jacek's boss, pondering how to phrase it so as to leave no doubt or controversy, ensuring further contact with his work was kept to a minimum.

"I'm telling you not to move, you spoiled bitch! Still not enough? If you don't calm down, I'll lash you to death, you anal slut!" Pati tortured Jacek with an impossible command.

Whack! Whack! Whack! Whack! Whack! Whack! Whack! Whack! Whack! Whack! Whack! Whack!

Bright red, bloody stripes marked him in a true web, a mosaic that turned his skin into a canvas for a sadistic painting. In some places, the skin had begun to crack and bleed.

Then, when she had had enough, Pati gave him a second injection, neutralizing the effect of the first. After a short moment, the dancing body calmed down and fell back into paralysis.

After writing and sending his resignation, Gabi put on her nylon gloves again and proceeded to the fourth series of chili sauce torture. This time, she rubbed it directly into the fresh wounds of the skin, cracked from the exhausting whipping. Jacek felt as if he were being torn apart from the inside by a thousand tiny points.

Pati took photos of his thoroughly battered body and uploaded them again to pornographic sites.

"Pati, do you know what I imagine that makes me so wet? I want to kill him in the most painful way possible. Imagine we throw him into a tub of boiling water; the boiling water squeezes the blood out of all his wounds like juice, the water turns red, the chili effect mixes with the burns, and from the pain, his dick lets go, and the blood in the tub mixes with urine. He dies in such a bath" – Gabi fantasized wildly.

"Sounds like a plan for the future," Pati replied.

Both burst into long, uncontrollable laughter.

Gabi became strangely quiet, thinking intensely. Without a word, she opened the bathroom door of the apartment and scanned the room. There was no tub, only a shower.

"You know what, Pati? I have to realize this as much as possible right now. I'll take him under the shower. I'll turn the hot water to the maximum. He dies, he dies. I have to, I can't stop myself!"

"Gabi, we were supposed to subject him to trauma, and then slowly train him into a bitch. If you kill him, you'll have a momentary orgasm and that's it; we'll have to look for the next victim," Pati tried to dampen her enthusiasm.

"I don't care. I have to do it."

"Okay, it probably won't kill him instantly anyway," Pati yielded with surprising lightness.

Gabi grabbed Jacek's limp body from behind by the arms and dragged him across the floor to the bathroom. She entered the small shower cabin with him and positioned him against the wall. Back to the wall, ass on the floor, arms slumped at his sides, legs helplessly splayed.

"We'll take this shower together, you slut."

She stripped off her tracksuit until she was naked. She stood over him, seeing how his gaze fixed on her tight, shaved cunt.

She turned the knob from the hand shower to the overhead shower and opened the valve to the maximum.

The water scalded her too, adding a slight touch of masochism to her sadistic delight. She watched as the wounds on Jacek's body turned crimson under the influence of the hot water. She knew that if he could, he would be screaming. The drug they had previously given him in vodka had a very specific and precise effect: simultaneous paralysis of the body and the inability to lose consciousness, even from extreme pain. This guaranteed that the victim in a torture like this would experience no relief, which would have spoiled the fun for a girl like Pati.

"Now look, you bitch, we're in the shower together. I've stripped. Admire my commanding body. But don't get any ideas. I would never give myself to a pathetic whore like you. Did you really think we came to celebrate your birthday?"

She was becoming very wet, scanning Jacek's body lengthwise and widthwise, observing how the destructive hot droplets scorched the redness and the wounds. The victim began to shake convulsively. Pati sensed that this truly threatened death.

And she didn't turn off the valve. Instead, she lifted his limp left arm and pressed his hand against her cunt.

„I'll do you this favor. See what it's like to touch a high-breed cunt. Go on, go on" – she steered his lifeless hand over her wet, peaking cunt – "I'm wet, I'm wet, I'm wet!" she screamed.

She pulled his hand back, which slumped back down along his body. She came, orgasming with a beautiful, majestic gush, and the juice sprinkled Jacek's protruding stomach.

"Aaaaaaaaaaaaaahhhhhhhhhhh!" she moaned, peaking.

"Gabi, did you kill him?" came Pati's voice from the apartment.

Gabi looked at Jacek's face. Closed eyelids. He wasn't breathing.

"Oh fuck, I think so!" she screamed.

"You stupid slut!" Pati screamed, bursting into the bathroom. She looked at the victim. "He's not breathing!" She immediately turned off the faucet. "Resuscitate him, you slut!"

"What? How?"

Wham!

Pati slapped Gabi hard across the face.

"Do what I say, rag, or I'll beat you so bad you'll never forget it! Mouth-to-mouth, now!"

In a state of shock and terror, Gabi began resuscitation.

"You better succeed, rag, because I don't know what I'll do to you! This is a perfect slave for years, not for killing after a few hours!"

Sweating and trembling, Gabi continued the resuscitation as best she could, although it seemed to be having no effect…

Teen Fire & Frost Sorority Slavers chp2 follows the story of two teen heroes, Teen Frost (Kara) and Teen Fire (Tara), who find themselves captured and tormented by a sadistic sorority led by Buffy Farnsworth and Kassie, the head cheerleader. Throughout the chapter, the girls are subjected to various forms of physical and sexual abuse, all while trying to maintain their own sanity and connection to each other. BIO Kara and Tara Bishop had both modeled growing up and had been pursued by some of the top agencies; it amazed most people that they were just stepsisters because they looked so alike. Both were 18 years old, 5’6” tall, and about 115lbs, both were extremely attractive girls with flawless tan skin and playmate looks. Both girls had perfect breasts, if not large for girls so petite and pert, toned, heart-shaped bottoms. They could very well have been sisters, even twins; they even shared the same birthday. As children, they hated to wear clothes, even as tweens and later teens, they never wore anything but tiny bikinis all year long. They altered their school uniform skirts, making them so short that they were sent home. Luckily, their father's law firm threatened to sue, and the school backed down. Both struggled with the fact that they had fallen in love with the other. As stepsisters, they were aware of the taboo of their relationship, so they kept their love a secret. They were both currently students attending Metro University on gymnastic scholarships; both girls have won dozens of trophies for fitness and gymnastics competitions, and loved to play beach volleyball. Team Bishop was ranked nationally in the sport. They lived together in a high-end condo off campus; both of their parents had died in a car accident two years before their transformation. Insurance and the sale of their father's business had left them both financially secure for life. Their true story began while the girls were traveling across the desert to a gymnastics competition. On a lonely stretch of the highway, the girl's car engine just stopped running. Soon after this, a bright light from above temporarily blinded the girls as an alien spaceship landed on the road in front of them. The being inside the craft emerged, but the girls were not afraid, but quite the opposite. The alien, called Mesha, communicated by thought, and the girl could do it too, and that ability remained after their visitor left. Leading the girls to be able to converse with each other telepathically. Mesha revealed that she was not there by chance. She was there to bestow power gemstones to both girls. The stones chose them and guided her to their location. A small red stone was given to Tara. Upon touching the stone, her hair turned a brilliant red, and she was endowed with the ability to manipulate fire. A small white stone was given to Kara. Upon touching the stone, Kara’s hair turned a striking platinum blond, and she was endowed with the ability to manipulate cold. Both found that the stones increased their physical strength and speed as long as the gemstones touched their skin. They were also impervious to physical pain, and their bodies could not be physically damaged. They did not need to eat or drink or relieve themselves, and they never aged. They discovered that even when they did not have the stones touching their skin, the residual energy from the stones kept their bodies resistant to physical damage: they could feel pain, though muted, and even be injured, but the injuries would heal instantly. But both teens could be subdued by knock-out gas, chloroform, advanced alien tech, and other attacks of this type. They decided they would use their powers for good and became superheroines. They found that each could call her stone to herself by touching her hands together in front of their faces and whispering the word Mesha; it would transform them into their new superhero personas, Teen Frost and Teen Fire. It would also bring the gemstones back to them if they were taken or lost. Mesha explained that the small bag used to contain their power stone possessed amazing properties. Both girls designed costume bottoms from the strange fabric provided by their alien benefactor, which the stones were wrapped in. The amazing material was impervious to damage of any kind and resembled wet metallic latex, feeling slick to the touch and fitting the girls' toned bodies like a second skin. The small amount of material available made them design their costume to match their beach volleyball outfit bottoms, but tinier and much sexier, showing off the round, firm cheeks of their amazing bottoms. The fabric could not be altered and would always remain their bottoms. The heroes found later that they could manipulate the fabric's shape; it would always remain their costume bottoms, but they could morph them into a thong or any bikini-type bottom. This morphing could not be done while they are wearing them. Mesha explained that for them to receive the stone's energy, the girls had to have the mysterious fabric touching their bodies, as it acts as a conduit for the power stone's energy. The rest of the costume was created from alien armor supplied by their new alien friend and consisted of a small top, arm sleeves, a belt low on their hips and snug on their waist with a letter F on the buckle and a pair of thigh high boots with five-inch heels rounded out the costume. They later relieved some alien bad guys that were trying to exploit the planet's mineral resources with two small antigravity backpacks, which gave them the ability to fly. Each girl’s gemstone was worn as a belly ring. Tara’s costume was colored metallic red and black, and Kara’s was metallic snow white and blue. Once the girls' costume bottoms were on, only they could remove them from their bodies, and they could not be removed if the wearer was under any type of duress, putting a damper on any villain or villainess' efforts to strip them of their complete costume. After wearing their new costumes, the new superheroines found there were side effects: Fire's costume bottoms would react when exposed to heat, which would cause extreme sexual arousal. Cold had the same impact on Teen Frost's costume bottoms. Mesha cautioned them that if the fabric had another side effect. Prolonged exposure to "magic" fabric, to her people, and most of the galaxy's inhabitants had an energizing effect, but with humans, its power seemed to affect the libido of the wearer. The girls soon found out that the effect of prolonged contact with the fabric made them horny, and the longer they were in contact with the fabric, the hornier they became. It also removed all inhibition, both inside and outside the bedroom. The benevolence alien warned that while wearing the enhanced bottoms, they should wear as little clothing as possible, and it was best to wear only the top, boots, and gloves she provides, as she did not know how the bottoms would react to the plant and petroleum-based clothing used on their world. The girls stated that they did not mind as they didn't wear much clothing anyway. They were both black belts in Aikido and Jujitsu, and both had trained extensively in Muay Thai and Krav Maga. The girls trained in escapology with a master magician. They worked as her assistants, and she taught the art of escape. The times they were bound by the beautiful magician they found, that were turned on by the tight bondage, causing them to use it in foreplay in their relationship, They later found that being captured by a villain or, more so, a villainess and being bound in extreme bondage, deathtraps, and predicament perils or sexual torture while bound would increase their sexual energy and provide them with earth-shattering orgasms.
