Simon
Karly was furious about not getting the chance to go clothes shopping with Eve, but after what their mom did, that won’t be possible anymore.
Anyway, it’s still too early to do what Karly had planned to do with Eve. I promised her she’d be able to buy clothes for her sister once her physical transformation is complete.
What she doesn’t realize is that she’ll never get the chance. I fully intend to make her, and her brother, disappear long before that ever happens.
I thought I’d need Karly and Kaden until the end of the year, but now that I have Mia and Zoe under my control, I need them far less than they realize. Especially since Karly’s becoming more and more annoying with her constant requests and complaints. And Kaden? He’s just too eager when it comes to hurting Eve.
They don’t know it, but those two are living on borrowed time.
Karly
Today, I’m heading off with Eve to spend the weekend at Zoe’s place. It’s a great opportunity, since her parents and most of the family will be away until Sunday afternoon. Actually, besides Zoe, the only one around will be her cousin Madeline, and she won’t bother us. She usually stays in her room anyway, probably still traumatized by the violent death of her family. We will have a lot of fun at Eve’s expense, in addition to making a first step for Simon in brainwashing my sister.
So, we arrive at Zoe’s place on this beautiful Saturday morning.
Zoe says: “I suggest we use Alexander’s room. He’s got his own place in the dorms near the Conservatory and barely ever comes home. From what he told me, he won’t be coming this weekend either, so it’s the perfect spot.”
Simon had let me know earlier that I was welcome to use that room, so we follow Zoe down to the basement, all the way to the room at the back.
It’s clean, nothing lying around and the bed’s made. Honestly, it’s even tidier than my room!
I say to Eve: “Eve, take the dildo off your ass and lie down on the bed.”
Eve does it immediately.
Zoe and I undress, then I sit on Eve’s face so that I can watch Zoe at the same time as my sister pleases me with her mouth. Zoe, who is standing and masturbating while looking at us, has one hand on her sex and the other caressing her breasts.
Zoe approaches me and leans over to kiss me. We French each other greedily and my excitement rises even faster. We moan with pleasure and suddenly Zoe pinches one of my nipples and I cum screaming, followed closely by my friend.
I hug Zoe while continuing to kiss her.
After a while, I stand up and Zoe takes my place on Eve’s face. For my part, I go to get one of the toys that Simon gave me and which is in the big bag I brought with me. It’s a Strap-on Dildo that not only will allow me to fuck my sister in the ass, but it also has a built-in vibrator that I place in my vagina and another part that touches my clitoris. It will give me pleasure both vaginally and on my clitoris, while I fuck my sister.
I settle between Eve’s legs, I activate the vibration of the fake penis and my harness, then I quickly penetrate her into her anus. Wow! The stimulation is very strong! I was a little afraid I wouldn’t cum with such an object, but I’m not worried anymore!
Eve
Zoe is on my face, and I’m licking her pussy as best I can. She loves what I’m doing; she moans with pleasure. Suddenly, someone spreads my legs and pushes their penis into my anus. Except I quickly realize it’s not a penis, it’s a vibrator!
The vibration is intense, and with that big thing thrusting in and out of my ass, it’s more than pleasurable. The excitement is building quickly.
Is that my sister fucking me like this with the dildo? Suddenly, the person pushes the dildo deep into my ass and doesn’t move for a moment. Did she just climax?
Karly
The pleasure of the dildo vibrating in my vagina and on my clitoris, but also the simple fact of being able to fuck my sister as if I were a man excites me to the highest point.
Zoe looks at me at the same time as she gets cunnilingus done by my sister and caresses her own breasts.
I do the same thing, and pinching my breasts the way I like and in an instant I cum. My vagina spasms firmly on the dildo and I see that Zoe is cumming too.
Zoe gets up and says: “I’m going in the shower; will you join me soon?”
I walk her to the door and I answer: “I’ll finish setting up for Eve and join you.”
Eve
Karly goes to the door with Zoe. It’s obscene to see her with a penis, even if it’s made of plastic. The worst part is that she made me cum with it! The movement in my ass of the hot and vibrating fake penis constantly turned me on and my body could not help but cum.
Karly closes the door, then she takes off the harness looking at me and she says: “Take off all your clothes now, it’s time for you to relax.”
I say nothing and I obey.
She brings a bag to the bed and takes out another dildo. A dildo in the shape of a penis, but even bigger than the other one and she shoves it into my ass. It’s a little painful, but it sinks into me without too much trouble.
My sister then takes chains and handcuffs out of the bag and says: “Spread your arms and legs wide.”
She puts the handcuffs on my wrists and ankles, then attaches chains to the cuffs and secures them to the legs of the bed. I find myself on my back, completely naked and completely open with my arms and legs apart. I can’t move at all.
I’m scared. Why does she chain me?
I want to speak, but when I open my mouth, Karly shoves some kind of large plastic penis into my mouth, securing it with some kind of elastic band, before blindfolding me.
Why is she doing this? What does she want to do to me?
I don’t know what it is, but I’m sure it’s going to be horrible!
Karly
Before I slipped the blindfold over her eyes, I saw the fear flicker in Eve’s gaze. She remembers what happened the last time she was tied up, and the pain that came with it. It was when she was fucked in the ass by our dog Max.
Still, her fear is pointless because this time, pain won’t be the issue. Quite the opposite, in fact.
Once the blindfold is in place, I take the two breast stimulators out of the bag. I place the first on one of her breasts, then the second on the other. The suction should hold them in place, but I reinforce them with duct tape just to be safe.
Then, I take out the clitoral stimulator and I put it in place, fixing it also well with duct tape.
I can’t wait to see how Eve will react when I activate the stimulators and the dildo all at the same time!
Finally, I put the headphones on my sister and hit play on the soundtrack.
Before leaving for the guest room, I tell her: “Rest well Eve, we’ll be back soon.”
Just before closing the door, I activate the toys with the remote control and observe my sister’s reaction with a smile!
Eve
I’m totally vulnerable and I don’t see what’s going on.
The headphones block the sound a bit, but since there’s no music, I hear my sister telling me: “Rest well Eve, we’ll be back soon.”
Suddenly, my senses explode! My breasts, clitoris, and ass are stimulated at the same time. It’s overwhelming and I can’t stop twisting and struggling against the cuffs.
My breast have suction on them, my clitoris has the same thing, but with also something resembling a tongue that touch me at a horrifying speed and that’s not to mention the stimulation that the dildo does in my ass! The dildo vibrates intensely.
It’s almost too much, I cum after a few moments.
It is at this moment that I hear in the headphones the voices of women who moan, pant and scream with pleasure.
The women’s voices, in fact, are mines! They recorded me!
Over the noise I’m making, I hear a woman’s voice, soft, almost calm. But the words coming out of her mouth? They’re horrible.
“Eve, you are made to cum and make pleasure to others. Your body has only one function, which is to give and receive pleasure. You’re a slut.”
“Your mouth is made to give pleasure to men and women, your ass is a receptacle for sperm and so is your vagina!”
Meanwhile, my breasts, and buttocks continue to be stimulated and I feel the excitement building inside me again.
The woman’s voice continues to tell me how I am a whore, a bitch, a slut, but at least the objects have stopped stimulating me. I don’t know how many times I’ve cum, but the last few times it was almost painful orgasms.
I tried to cry out for help, even though I know it’s useless, but it was too much! Can we die from climaxing too much?
Despite the sound of the woman’s voice and my moan of pleasure, I feel sleep taking hold of me.
Suddenly, the stimulators start moving again and I start screaming into my gag and crying because I know that no one is going to help me.
Karly
After enjoying the pool and relaxing in the sun, it’s time to go see Eve.
When I open the door, Eve doesn’t move and the vibrators are obviously paused in the program. I take off my bikini bottoms and approach my sister’s chained body. I don’t want to have to redo the whole set up, so I’m just removing the gag.
Eve tries to speak, but she doesn’t have time to do so; I’m already on her face and I say: “Come on, little whore, you know what to do.”
She obeys immediately, and her tongue quickly finds my clitoris. Meanwhile, Zoe, who has taken off her swimsuit, approaches me and she says: “So, your sister doesn’t really have big breasts, just padded bras”.
Overwhelmed by my need to have my sister tongue on me, I’d forgotten that Zoe didn’t know the truth. I answer: “Yes, even if in fact, they have grown a little in the last few months, they are still small. For now, at least. But it’s a secret, you mustn’t tell anyone. Got it? Simon would be mad if you tell it to anyone.”
Zoe leans down and says: “I understand, Mistress.”
Then she kisses me greedily while firmly grasping my breasts. With one hand, I hold my sister’s head against my sex, and with the other, I caress one of my friend’s lovely breasts.
The pleasure builds quickly, and just moments before I climax, the vibrators start up again. Eve screams against my sex, and I cum all over her face.
I stand up, and Zoe takes my place.
Eve
I spent the day having orgasm after orgasm, with short breaks from the vibrators. Occasionally the two women would remove the plastic penis from my mouth so I could make them cum with my tongue.
At dinnertime, Karly freed me from the chains and sex toys and took me to the shower. There, I was again forced to make them cum with my mouth, one after the other.
After eating pizza, where I was forced to suck the delivery guy off for a tip, I thought my hellish day was finally over, but I was wrong.
Because Karly took me back to Zoe’s brother’s room, chained me up again, and reinstalled the sex toys.
After she finished setting everything up, and just before the soundtrack started playing again, she said: “Have a good night, my little whore!”
Madeline
I’d stopped watching Eve’s torments to get some sleep, but a sound from the computer woke me up.
The alarm had gone off. Someone pushed open Alexander’s bedroom door and stepped inside. When I got closer to the screen, I expected to see Karly or Zoe or both. But it’s Alexander! What’s he doing there?
Alexander
I slipped quietly into the house and everything was still. To my relief, Zoe and her friends hadn’t thrown a big party to take advantage of our parents being away. I was relieved. I came here to crash, not clean up after teenage chaos.
Back at my place, my roommate had pulled a classic move: football night, surprise guests, and zero heads-up. The game ended hours ago, but the party? Not so much. I left them to it. All I wanted was silence and get some sleep.
I tiptoed into my bedroom keeping the lights off as I began to undress. That’s when I heard it. A noise from the bed. My heart jumped. I flipped the switch ... and nearly fell backward.
Someone was in my bed.
Not only that, the woman, because she is a woman, is completely naked and chained, with her arms and legs spread wide. She has a gag over her mouth and a blindfold, in addition to having what appear to be sex toys on her breasts and genitals.
The woman screams into her gag, and I approach to try to remove it. Once I unclip the clip holding the object in place, I remove it (along with the earphones and the blindfold), and instead of being a simple ball, it’s shaped like a penis and was pushed deep into her mouth. As soon as it is removed, the young woman cries: “Please, stop this, I can’t take it anymore!”
Madeline
He’ll ruin everything if I don’t intervene.
I approach the door to his room and listen to what’s happening. Maybe Alexander will simply take advantage of the opportunity and fuck Eve, but I have serious doubts. I’m almost certain my cousin is gay. Anyway, the slut’s virginity belongs to Simon, I’m not going to let my cousin steal it from him.
I listen to Eve explain why she’s there, how she’s under the influence of her siblings thanks to blackmail based on videos.
Alexander offers to help Eve, to go to her house to find the videos and destroy them. This way, Eve would be free. I approach quietly to look into the room. Alexander is sitting on the bed next to Eve and is obviously about to remove one of the vibrators from Eve’s breasts.
Alexander
“When I removed the gag from her mouth and the blindfold from her eyes, I recognized her. It’s Eve Smith. One of my earliest friends from way back in grade school. We lost touch after she got held back a year, just drifted, I guess. But what she just told me ... it’s beyond horrifying. I have to help her.
During the conversation, the vibrators stopped working, but they just started working again with renewed vigor, and I lean down to remove one of the ones stuck to her breasts.
Suddenly, Eve says, “No, don’t take them off. Put the plastic penis back in my mouth and the blindfold over my eyes. Karly can’t know you’re helping me. The important thing is that you find and destroy the videos.”
So, I put everything back the way it was when I arrived and prepare to leave the room when suddenly, I feel a sharp pain in my back and collapse to the floor.
Madeline
I’d never used my taser before, but after two jolts on my cousin, he dropped, out cold. I left him there with Eve, who has just cum again like the little slut she is, and shut the door. Then, I headed back to my room.
My hands were shaking a little when I picked up my phone.
I dialed Simon.
Simon
Alexander would not have been able to find videos in Eve and the twins’ house, but he could have had the idea to alert their parents. It could have derailed my project.
Fortunately, Madeline intervened and even offered a solution to get rid of Alexander.
I’m not going to follow her plan to the letter. I won’t kill Alexander. I have a far better idea, one that’ll let me give Madeline a very special gift on her eighteenth birthday.
Simon
On this sunny Tuesday, Madeline (who claimed she was too sick to go to school) and I boarded Valeriy Tamarov’s yacht. He represents the Tamarov family and is the brother of Svent Tamarov, who married one of Madeline’s aunts. Valeriy doesn’t bother pretending to be normal. He’s dangerous, and the Tamarovs aren’t just Russian, they’re deep in the Russian underworld.
The meeting went fine, though. We spent a lot of time discussing the problem with the twins. They’re going to take care of it. It’ll take some time, but in the end, the twins won’t be anyone’s problem anymore. It won’t just be the twins who will be out of the picture, but honestly, I don’t care. Valeriy’s looking at it like a win-win for both sides, and I couldn’t agree more.
After that, if their thorough vetting process goes as expected, Madeline and I might secure a spot in a larger operation. Not the Tamarov organization, of course, but something much bigger, much more complex. Once in, we’ll have access to a broader catalog of slaves. More reach. More variety. The perks are worth it!
Eve
It’s Friday morning, and I’m licking Mia’s pussy in the women’s locker room. Tomorrow it’s going to be a week since I spent almost 24 hours chained to Alexander’s bed and forced to climax almost nonstop.
I didn’t have much hope that Alexander would manage to take the evidence and free me from the twins’ grasp, but I’m still disappointed when I hear Zoe explain to Karly and Mia that Alexander left school and sent an email saying he was going on a world trip to figure out what he really wanted to do with his life.
He left me to my fate instead of trying to help me. I shouldn’t, but I start crying while continuing to bring Mia to orgasm.
Simon
Even though Eve’s still feeling a little down about Alexander’s disappearance, she’s been smiling more around me. We had another nice evening together at the place she thinks is my home, sharing a meal she believes I cooked before she arrived. In reality, Jasmin dropped it off just a few minutes before Eve showed up.
After dinner, instead of playing sex games with her there, I suggest we go see a movie to relax. She probably thinks we’re going to a regular theater, but I take her to an industrial neighborhood where ‘The Sensual Spot’ is located. It’s a sex shop that includes a small viewing room for pornographic films.
Before getting out of the car in the store’s parking lot, Eve asks, “Didn’t you say we were going to see a movie?” I give her a big, friendly smile and say, “There’s a small movie theater in this store, Eve. Trust me, it’s going to be fun!”
Eve
Dinner was so good, Simon’s actually a great cook. But honestly, it wasn’t just the food. Talking with him made everything feel ... softer. Like I could breathe again, even with everything that happened with Alexander and the twins. He didn’t say anything, but I felt it. That maybe he sees me the same way I see him. And maybe, someday, we could get married. I know it sounds crazy ... but it would be kind of amazing.
Except now he wants us to go watch a movie in a sex shop! I know perfectly well they’re not gonna be showing some new Disney release! I’m a little worried, but it’s Simon and he’s not like the twins. He’s not going to force me to have sex with strangers. I have to trust him! So, I get out of the car and we walk together, hand in hand, into ‘The Sensual Spot’.
I’ve never been in a shop like this before, and honestly, it’s kind of overwhelming. There’s stuff everywhere, so many things I don’t even recognize. Like, what do people even use half of this for? I barely get a chance to look around, though. Simon heads straight to the back, and I follow him. As he said, there is a door that leads to a movie theater, but there is already a movie playing.
On the screen, there is a woman in a large bed being fucked by two men. One is using her vagina, and she’s performing oral sex on the other. She’s very pretty and has big breasts.
In the small movie theater, a few people are here, each sitting far apart. We head to the back row, first row from the door, and I slip into the aisle seat. Simon follows me in. There’s just one guy at the other end of our row, totally locked into the screen.
We don’t say anything. For the next few minutes, we just sit there, watching.
I’m very embarrassed; I just realized that several of the men present have their penises out of their pants and are masturbating while watching the movie.
Then, a man and a woman enter the theater and sit a few rows down, almost directly across from us. The young woman got bright red hair and skin so pale she almost glows under the lights. She’s seriously gorgeous, and her outfit doesn’t hide much. The guy she’s with? He’s pretty cute too, I guess. But he’s no Simon.
On screen, a third man arrives and he start to fuck the woman in the ass. She pulls the penis out of her mouth and yells: “Harder!”
We watch the movie for a while, and even though I’m still embarrassed by what’s happening, I can feel my sex lubricating with excitement.
I notice the red-haired woman in front of us isn’t watching the movie anymore; she’s leaning over the man with her, and even though I can’t see exactly what she’s doing, her up-and-down motion is clear. She’s giving him a blowjob!
It’s also at that moment that I feel a hand slide between my legs. It’s Simon leaning over me and whispering in my ear: “Spread your legs wide so I can make you come, Eve.”
At that moment, I’m frozen, not knowing how to react.
Simon adds: “Let it happen. No one will be able to see your pussy, but I’ll be able to give you an orgasm.”
I obey and spread my legs. He he caresses my vulva and especially my clitoris. Simon leans over to kiss me, his tongue moving back and forth in my mouth. I cum almost immediately. I must have been more turned on than I thought!
Simon stops touching my clitoris, but he continues to kiss me passionately for a while. Then he sits back upright in his chair to continue watching the movie, keeping his hand between my legs.
The same woman on the screen is now alone on her bed, masturbating while looking at the audience.
The redhead is now sitting on top of her lover, having sex with him while watching the movie. The man, a little taller than her, is also watching the film while caressing her breasts.
That’s when I notice that Simon has taken out his penis and is gently masturbating while looking at the screen. I hesitate a little, we are in public after all, but I finally reach for his penis to masturbate it with my hand. He looks at me with a big smile before looking back at the screen.
