Simon

It’s Friday and Right after first period, Karly took Eve to a private clinic where I’d already booked the appointment. Under general anesthesia, Dr. Garado, a top-tier plastic surgeon with an insatiable love for money, suctioned a generous amount of fat from Eve’s stomach. That fat will be repurposed later, mixed with stem cells and a cocktail of hormones, to give her the breast augmentation that I want her to have.

They skipped math and chemistry so the good doctor could finish his work uninterrupted. When they returned, Eve had a tidy little doctor’s note excusing her from P.E.

I can hardly wait to set the next phase of Eve’s physical transformation into motion. It’s coming very soon, and when it does, she won’t even recognize the girl she used to be.

Eve

I don’t feel well at all. The surgery was a success, according to Karly, but even though I don’t feel as dizzy as when we left the clinic, my stomach still hurts, and so does my head. All of this just to remove a bit of the fat from my stomach, which wasn’t even that much big to begin with!

The only positive thing about this operation is that Karly and Kaden left me alone for the rest of the day. We went straight to the bus stop instead of, like every Friday, spending a long time at “The Nest.” And on the bus, I was able to sit in my usual spot, one of the front seats.

Karly also told me that for today and the rest of the weekend, I can just take it easy. She and Kaden won’t ask me to do anything for them. I’m pretty happy about that!


Madeline

I’m in downtown Miami, at “Le Tsar,” an upscale restaurant in the heart of the city owned by my uncle, Svent Tamarov. It’s almost 8 p.m., much later than I’d planned, but my uncle made me wait. At least the food’s good. It better be, at these prices!

Zoe and Mia are also in the restaurant, but they are at another table at the back with Elisabeth and Claire, Zoe’s sisters. For now, they are enjoying the good food and free alcohol. It’s going to cost me a pretty penny, but these bitches will serve as an incentive to convince my uncle to go along with my plan.

Svent finally shows up, slides into the seat across from me, and flashes a smile: “Hello, my beautiful niece. I’m glad we finally get to meet. Valeriy wasn’t lying when he said you were incredibly fuckable.”

I expected comments like that from him, but not so blunt and direct.

I just smile and reply: “You have good taste, Uncle, but that’s not why I’m here. I have a different kind of proposal for you. A proposal that’ll allow you to meet four of my friends, just as beautiful as me, who’d love to spend some time with you.”

I point to the table where my cousins and Mia are sitting, and my uncle smiles broadly and says: “Interesting, I’m listening.”

Simon

I wasn’t entirely sure it was a good idea to ask the Tamarovs for help staging the attack on Eve. I don’t want to be further indebted to that organization, but I have to admit, Madeline’s plan is flawless. It minimizes the chances of getting caught while ensuring Eve ends up in the hospital with injuries severe enough to justify Dr. Garado’s involvement.

The only payment for his participation in the plan will be to use Mia’s and Madeline’s cousins’ bodies over the weekend.

What a bargain!


Eve

When I got up this morning, I realized that my stomach almost doesn’t hurt anymore and my headache is totally gone.

Karly never mentioned again what she had planned for me after the Winter Formal, namely that I should lose my virginity to the highest bidder.

I’m so glad it’s not going to happen, thanks to my father’s intervention about getting on the pill. I want to stay a virgin until I get married.

Still, I’m not delusional. The twins are seriously determined, and I’m afraid they’ll find a way around my dad’s rules eventually.

In the meantime, I’m really happy I get to go to the Winter Formal this year.

In past years, Mom and Dad always said no, claiming I couldn’t go alone. But this year, they can’t use that excuse, even if I’m going with the twins.


Karly

Eve seems to think that what we had planned for her after the Winter Formal, the selling of her virginity, won’t happen because of Dad’s decision. She’s completely wrong.

Simon still wants the planned after-party to go ahead, no matter what. He told me he’s already put a solution in place, though he didn’t give me any details.

I’m absolutely sure he’s telling the truth. He’s proven it to me over and over again: He always gets what he wants, no matter what stands in his way. What he did to Mia and Zoe is the clearest proof of that. I’m still terrified at the thought that he might come after me next. Thankfully, I’m part of his plan. He needs me and Kaden to keep going.

Today’s Saturday, and Mom decided to come with me and Eve to shop for our dresses for the Winter Formal.

Kaden was with us at first, but a suit, pants, a tie, and some new shoes, yeah, that doesn’t take long. Even his mask, since it’s a masquerade this year, is just a plain white Venetian one.

For us, it’s not that simple. We’re getting ball gowns, matching shoes, and more interesting masks, especially ones that go with the whole outfit. That’s going to take a lot more time, obviously, which is why Kaden already took off.

Eve

I’m so glad Mom helped Karly and me find our outfits for Winter Formal! I was really worried I’d end up doing it with just Karly, and I’m pretty sure if that had happened, I would’ve walked out in something that showed off my curves way more than I’m comfortable with.

It took forever, and I’ve got to admit I’m pretty tired now that the day’s over. But at least we found the perfect outfit for me.

Mom picked out the dress with me, but honestly, she did most of the choosing. It’s this deep midnight blue, and when I first saw it on the hanger, I thought there was no way it would look good on me. I mean, with my chest, even if it’s not my real breasts, I think that dresses like that usually don’t fit right. Either too tight or way too open. But this one, it actually worked!

The top has some structure to it and it holds everything in place without making me feel like I can’t breathe.

The skirt flows in layered chiffon and moves so beautifully when I walk. It actually makes me feel elegant.

My shoes are dark blue heels and not too high, thankfully. Mom made sure they were comfortable. She always says if I’m going to wear something fancy, I shouldn’t have to suffer for it.

And then there’s the mask. It’s probably my favorite part. It’s a Venetian-style piece in icy blue and cobalt, with little silver details and some soft feathers. It’s both spectacular and delicate, and it matches everything perfectly.

Mom was definitely not happy with the outfits Karly wanted to pick. Her dresses were always way too low-cut and tight, the heels way too high, and the fabrics way too revealing. In the end, Mom backed off a little, and Karly agreed to compromise, at least a bit.

Still, Karly’s outfit, in shades of red, is way less modest than mine. The neckline plunges and shows way more cleavage than what she usually wears. The heels are high, though not as high as she wanted, and her mask is actually similar to mine, unlike the “atrocity” (Mom’s exact word) she originally wanted to wear.

I stayed out of it, but honestly, even with the way things are between Karly and me, I can’t help but admire what she’s going to wear. It’s bold and fiery, and it really shows off her curves.


Simon

Today, just as I’d hoped, Karly asked for permission for her and her brother to skip the evening celebration marking Eve’s new status. I had presented the event as a casual party with the twins, a few close friends, and of course, Eve as well, the day after the Winter Formal.

From the very beginning, I knew it would never happen. Valeriy Tamarov had kept his part of the deal and set the trap.

Without dwelling too much on it, I made it clear to her that while I was granting their absence, I wasn’t exactly pleased that the twins were bailing on me.

Karly

It went better than I feared. Yes, Simon wasn’t thrilled that Kaden and I couldn’t attend the party he’s throwing to mark the end of Eve’s virgin status, but he didn’t push us to be there.

I do enjoy playing with Eve, but Claire’s new boyfriend is insanely rich, and he’s taking us out to sea on his yacht. Claire says some of his family will be there too, all gorgeous and loaded. Maybe I’ll snag a rich boyfriend of my own!


Eve

It’s Friday, and I’ve got a bad feeling about tomorrow.

Today, just like last week, the twins left me alone all day, except for the usual blowjob I gave to Kaden and the cunnilingus I did to Karly this morning. I was able to sit in my usual spot without having to join Karly’s group at the back of the bus. That was true both going and coming back. Even after school, we headed straight to the bus stop instead of going to “The Nest,” like we always do on Fridays.

And then, right before getting off the bus, Kaden said something to Angela about a surprise waiting for me after Winter Formal, that I was going to give a lot of pleasure with my body. He also talked about all my orifices, but I might have misunderstood, and he immediately changed the subject.

Are they really going through with their plan, even though I’m not protected?

I wish I could talk to Simon and have him reassure me, but we won’t be able to see each other tonight because he’s out of town for the weekend!

I hope I misunderstood and that they will just sell my mouth and my ass, but I’m afraid that tomorrow I’m going to lose my virginity, whether I like it or not.


Eve

It’s finally Saturday, Winter Formal day, and I’m excited, nervous, and honestly, kind of uneasy.

This morning, when I went into Karly and Kaden’s room, they both told me to go back to bed. Said they didn’t need me for anything today.

Karly

Kaden is such an idiot. His comment in the bus about Eve yesterday tipped her off way too much. He shouldn’t have said anything! Simon had given clear instructions.

At least Eve seems to be keeping her worries to herself, and Mom thinks she’s just really nervous about tonight’s party.

To be fair, Mom is in full prep mode right now. We’ve got an appointment at the salon, then we’re getting ready at home before her friend, who’s a makeup artist, comes over to give us a look that’s supposed to hold up under masks.


Madeline

It’s Saturday morning and Simon and I are on the top floor of a big hotel in Miami, where we spent the night together. Yesterday was my 18th birthday, and by the end of the day, we got married at City Hall!

Simon is an incredible lover, far beyond anyone I’ve been with before. Not only is he well-endowed and knows exactly how to use it, but his stamina is extraordinary.

That said, our relationship isn’t just about sex. We’re so alike, like two sides of the same coin. I was a bit worried at first, wondering if our dominant personalities might clash, but it turns out that sharing control makes everything even better. I can’t wait to start having fun with Eve.

We’ve just made love again, and now we’re lying on the bed, the sheets tossed aside, when the door opens without warning and a young woman walks in. I don’t even have time to react before Simon says: “Perfect timing, Alexandra!”

The young woman has pale blonde hair cut short and green eyes. She’s not particularly beautiful, her figure is slim, with small breasts, but her face reminds me a lot of Zoe’s. Maybe she’s a cousin from Uncle Ashton’s side? That might explain why she feels familiar.

She doesn’t smile. In fact, she seems almost completely emotionless. I don’t think she’s happy to be here, but she’s staying calm.

Simon turns to me and says: “Darling, this is Alexandra, our new slave. She’ll start by taking care of me, then she’ll focus on giving you pleasure.”

Without saying anything, Alexandra kneels in front of Simon and takes his soft cock into her mouth.

After a few minutes, as Simon alternates his gaze between our slave pleasuring him and me gently touching myself, he’s hard again.

He pulls himself from her mouth and gestures for Alexandra to come to me.

Without a word, she moves between my legs and begins to lick my pussy.

Meanwhile, Simon steps behind her, lifts the back of her dress, and enters her, fucking her from behind.

Alexandra is really good at licking my pussy, and my excitement builds very quickly.

That said, it may also be because I’m watching Simon fuck her at the same time.

After a few minutes, I climax, and since Simon isn’t finished, I hold Alexandra’s head on my pussy so she can keep licking me.

When I’m close to coming again, Simon speeds up his thrusts before finally stopping, ejaculating into the young woman between us.

I orgasm a few moments later.

Simon says to Alexandra: “Turn around and clean my cock.”

Alexandra, still on all fours, turns toward my husband, and I realize, looking at Alexandra’s buttocks, that Simon has fucked her in the ass, but more importantly, that Alexandra is not a woman! I look at Simon, and he says to me with a smile: “Surprise!”

I then realize who Alexandra is and that Simon didn’t kill Alexander after all.


Eve

Mom dropped me off with the twins in front of the big building where the Winter Formal is being held. There are other students arriving at the same time, the guys looking sharp in their suits and ties, and the girls looking gorgeous in their ball gowns. At first, I don’t recognize anyone because of the masks, but two women walk toward us, and when they greet the twins and Mom, I know it’s Mia and Zoe. Their dresses, just like Karly’s, hug their curves beautifully. Mia’s is turquoise, and Zoe’s is a shade of green that makes her eyes pop.

Mom wishes us a good evening and leaves. We head inside the grand ballroom together.

After the principal’s speech and the one from the head of the event committee, the night officially begins.

A lot of people head straight for the dance floor, but Karly grabs my hand and says: “Let’s go to the photobooth.”

That’s fine by me, I’ve never danced, so I’m not about to argue about doing something else!

The photobooth is in a room adjacent to the ballroom.

There are several backdrops for photos, but we mostly use the one that makes it look like we’re in a snowy northern forest, with branches weighed down by snow. We take several sets of pictures, first with me and the twins, then with Mia and Zoe. The photobooth attendant is super friendly, cracking jokes to make us smile, and I’m pretty sure the results are going to be amazing.

I almost forget that I am with the twins and the other women who have been abusing my body for months.

We have been there for a few minutes when other students, including Angela, arrive and suddenly, one stands behind me to hold my arms behind my back and two others place their heads close to mine and each grab one of my breasts through my dress. The person in charge of the photo booth doesn’t react, except to smile broadly and continue taking pictures, encouraging us to smile. I don’t feel like smiling!

Angela yells at me: “If you don’t smile, we can make you cry!”

Karly adds: “Come on, Eve, give us a nice smile!”

Karly

Eve participated well with us for the usual group photos, but it took a lot of effort to get her to pose for more sexual photos while smiling. Several groups of students wanted photos with my sister while grabbing her breasts. We can’t really say she smiled broadly, but after more specific threats, Eve smiled at least a little.

Then we took another series of photos with Eve playing with a dildo that looked like it was made of ice. We made her pose with the dildo deep in her mouth while she caressed her sex through her dress. Then we made her lift her dress and pretend to masturbate with the dildo while feigning to enjoy it.

It was fun, but now it’s time to dance.

Eve

The photobooth was awful, but now it’s over, and the others went off to dance without saying anything.

I quickly lose sight of the twins and the other girls.

I’ve lost all interest in the party. If I could, I’d ask my mom to come pick me up right now, even if I had to say I have a stomach ache. But I know I can’t do that; the twins won’t let me do it.

As for dancing, I don’t feel at all comfortable going onto the dance floor. I don’t have a partner, and besides, I’ve never danced at a party like this. And even though my dress is amazing, I’m just not comfortable moving around with what must be considered by many as huge boobs.

I’ve been watching people dance for a few minutes, admiring the gorgeous dresses the girls are wearing, when a guy approaches me and extends his hand, asking: “Wanna dance?”

I don’t know who he is because of the white mask he’s wearing, but we’re in public, and the principal is watching the students with several teachers. So, unlike the photobooth, nothing can happen here.

The guy dances with me for a few minutes, with movements somewhat similar to the other dancers, and I try to follow his lead. For a moment, I actually enjoy being part of the group, having a guy dance with me and look at me in a friendly way.

Suddenly, he takes me in his arms and continue dancing, pressing his body against mine. The others continue dancing and I see that some of them are watching us and smiling. I don’t want to make a scene, at the risk of the twins punishing me. Especially since the man who is pressing himself against me is doing nothing more than that. At least, during the first few moments. Because after that, he grabs my buttocks to pull my body even closer to his, and I feel his erection through my dress. The man then whispers in my ear: “We’re going to have a lot of fun with you, bitch!”

Then he lets go of me and I find myself in the arms of another man who immediately takes me in his arms and also grabs my buttocks to press his body against mine. He even moves back and forth as if he were fucking me. I try to see if the principal or the teachers can see what is happening so I can ask them for help.

I immediately realize that they can actually see me, because the man who is groping my buttocks and I are in a dance circle several feet away from the others. The circle is made up of several students, including Karly and her friends, as well as Kaden and Angela.

The principal looks at me and smiles without saying anything. Wanting to ask the teachers for help, I realize that the two closest to the principal are James Mitchell and Marco Rossi. There’s no way they’ll do anything to help me. They too are smiling at me. A little farther away, there are Lauren Turner and Georges Papadopoulos. Those two teachers aren’t smiling, but even though they glance toward me from time to time, it’s clear they won’t do anything to help.

The man who’s groping my ass finally let’s go after whispering in my ear: “I can’t wait to fuck you, Eve.”

I recognize that voice, it’s Noah’s, Mia’s brother.

Karly

During several songs, Eve danced with different students who enjoyed fondling her buttocks. In one instance, a second man even stood behind her and fondled her breasts through my sister’s dress.

Despite the mask, it’s obvious my sister is crying, and it’s time to move on to the next step.

I approach Eve when one of the dancers lets go of her, and I take her hand, whispering in her ear: “Come with me, Eve, I think you’d be better off resting for a bit.”

I lead her toward the back of the room, then we exit the building to head into a nearby one.

We enter a small room that’s usually used for gymnastics, yoga, or other activities like that. All the walls are covered in mirrors.

I say to her: “Now, Eve, get completely naked.”

Eve looks at me and says: “Why?”

She hasn’t questioned me like this in a long time. I’m sure it’s because of what Kaden told in the bus yesterday that she dares to question a clear order.

I reply in a firm voice: “You obey, and that’s it!”

Eve takes off the mask, and I see that she is afraid of what will happen to her.

Then she removes the dress, the bra, and finally the dildo that was still in her ass.

I take everything and head for the exit when Eve cries out to me: “Karly, are you leaving? Are you leaving me like this?”

I turn back to her and reply with a smile: “Take advantage of this break to rest. You’re going to need it!”

Eve

I lay down on the floor. I couldn’t bear to see myself naked like that in that big room.

I stayed on the floor and cried for a long time before finally stopping.

I’m sure that this time, it’s true, I’m going to lose my virginity.

I thought about what Simon would have advised me to do.

I don’t want to lose my virginity tonight to a stranger who paid to rape me like this, but there’s nothing I can do about it.

I just have to remember that one day, a man will love me enough to forgive this loss and will want to marry me anyway.


Eve

I don’t know how much time has passed, but when the door to the room opens again, I’m calmer. Not happy, but calmer. I turn my head and see that Karly is back with Mia and Zoe. Two other women enter with them.

Karly and her friends have changed and are now wearing identical, light, elegant sky-blue dresses. They’re no longer wearing their masks.

There’s a woman I don’t recognize with them. I don’t know who she is, but I think I’ve seen her before.

Is she one of the women I was forced to do sexual things with? Her hair is pale blonde and cut short, and her eyes are green. She looks a lot like Zoe. Maybe she’s Zoe’s cousin, that might be why I think I’ve seen her before. She’s wearing a soft green dress, her makeup is perfectly done, and her nails are painted a matching shade of green, all neat and shiny. She’s not alone. Another woman is with her, wearing a blood-red dress, and unlike the others, this one is still wearing a mask. But it’s not a mask for the ball. It’s a red mask, shaped like a demon’s face.

The five women stand around me without saying a word. I don’t even try to hide my nakedness; Karly wouldn’t let me anyway, and she might even use it as an excuse to punish me.

An old man enters the room. He is wearing a priest’s robe and approaches me with a smile. I had heard that some priests were perverted, but I didn’t believe it. However, now I have proof, because the man takes out his already hard penis and Karly says to me: “Eve, give our friend a blow job.”

I kneel down and take the man’s penis in my mouth. He does nothing, he lets me do it, and I do my best to get it over with quickly. I suck and use my tongue to caress the man’s member in front of me.

As soon as he starts ejaculating his particularly foul-tasting semen into my mouth, he pulls back and some of the semen ends up on my face. I would like to wipe it off, it’s disgusting, but I’m not doing anything, I’m waiting to see what they tell me to do.

The woman with the demon mask says firmly, pointing to the woman in the green dress: “Come on, Alexandra, go clean the officiant’s penis and testicles.”

I finally know who this woman named Alexandra is and why I felt like I’d seen her before. It’s awful, but I’m sure I’m right. Its Alexander disguised as a woman! He throws a quick glance at me before walking towards the man without saying a word. He kneels in front of the priest before starting to lick the man’s penis and testicles.

I look at Zoe, and she doesn’t seem surprised or bothered by her brother doing this. In fact, Zoe smiles as she watches her brother transformed into a woman. I don’t understand how this is possible.

Karly

After a few minutes of having his penis and balls licked by Alexandra, another cousin of Zoe’s, the priest leaves the room to go to the room where the ceremony will take place. I don’t know if Alexandra has also been conditioned by Simon or if she is just being manipulated by some kind of blackmail, but she gets up to go and stand next to Johanna, the woman wearing the demon mask.

I don’t know who Johanna is, only that Simon told us to obey her.

Kaden

The little slut is finally going to lose her virginity, and we’ll be able to have even more fun with her.

Not to mention that Simon says her transformation is going to happen sooner than expected, and I’ll be able to torture my sister’s breasts again.

The slut’s real breasts are a little bigger than when she started school. They’re probably a B cup now? But after the transformation, they should go up to a DD. I hope Simon is right and that those huge tits will be as sensitive as they are now.

Angela and I have ideas for tattoos to place on different parts of her body, along with piercings. Karly wants to buy her clothes, but I’m more focused on leaving a permanent mark, and more importantly, making her suffer as much as I can while doing so.

But anyway, that’s not for right now. Because now it’s time to make a deposit on my slutty sister’s breasts.

Eve

Alexander returns to the woman wearing the demon mask.

Kaden, whom I hadn’t seen come in, approaches me and take out his penis before thrusting it into my mouth. I start giving him a blowjob, and this time he let me do it without saying anything or forcing me to take it down my throat.

I keep going down on him for a while, then he pulls out and masturbates while looking at me with his mischievous smile. He ejaculates, and his hot, disgusting semen splatters my face and breasts.

It’s disgusting, I want to wipe the cum off my cheeks and breasts, but as long as they don’t tell me what to do, I don’t dare move.

Kaden leaves the room and Mia, Zoe, and Alexandra stand in a semicircle in front of me.

The woman with the demon mask says: “Karly, you know what you have to do, go ahead.”

It’s weird. Who is this woman, and why does Karly just listen to her?

I watch Karly leave the room, and no one says anything. They all just stare at me. Mia and Zoe are smiling, but Alexander’s face is blank, like he’s in some kind of daze.

Then, a few minutes later, Karly and Angela come back into the room. Karly’s holding two blindfolded guys by the hand. They’re two students who always show up at “The Nest” on Fridays. Angela’s doing the same with another guy, who I recognize as Professor James Mitchell.

Karly and Angela place the men near Mia, Zoe, and Alexander, who kneel in front of them. Then they take out their penises and put them in their mouths to suck them.

I don’t do anything. I just hope whatever happens next doesn’t involve me, but honestly, I’m not holding my breath.

In fact, a few moments later, I see that I was right, because the three of them get up and stand behind the men to masturbate them. Now I know what they want to do. They want to make the men ejaculate on me!

It’s a strange scene. I’ve never been placed like this in front of three erect penises being masturbated by women’s hands. Although Alexander isn’t a woman, it’s the same thing in these circumstances.

A few minutes later, the first jets of semen are sprayed onto my face and breasts. Then a second man ejaculates, and the semen falls directly onto my breasts.

Finally, James Mitchell ejaculates into my hair and onto my face. One of the jets falls into one of my eyes, and I can’t keep it open. I start to raise my hand to at least remove that semen, but the woman in the demon mask shouts: “Don’t move, bitch!”

With my one open eye, I see Karly and Angela returning with the three men, still blindfolded, to the other room.


Karly

After being covered in semen from about three dozen students and professors, Eve is covered from head to toe with it. She can’t even open her eyes because they are both covered in semen.

Now it’s time to move on to the next step. That is, dressing Eve in her wedding dress!

I approach her with the prosthesis that simulates my sister’s enormous breasts and lean over her to say: “I’m going to dress you, Eve, just let me do it.”

I put on the bra without too much difficulty because Eve raises her arms to help me.

Then I help her stand up, and with Zoe and Mia’s help, we pull the white dress over my sister’s head.

Simon was able to create a perfect copy of my mother’s wedding dress! I know it’s a copy because he told me so, and also because the bust has been altered to accommodate my sister’s bigger breasts. It’s still a beautiful wedding dress, even if it won’t stay that way for long.

I comb my sister’s hair as best I can, sending the excess semen toward her face.
