[Marquise]

I storm out of my bedroom to find Theo in front of it and shove him hard on the chest causing him to stumble backwards.

"What part of the rules you didn't understand?" I reprimand as he regains his balance. "What did I tell you about how I should be addressed?"

He opens his mouth to answer but I don't give him a chance. "Here's the thing, slave, you disrespected me. And you should think twice before disrespecting the one person standing between you and complete social suicide. Or what do you think it will happen when I post your picture. Oh, right, you don't think. That's your problem."

The more I talk the more agitated he becomes, which only makes me want to be meaner. I step forward, getting dangerously close to him. He smells of cum and soap, a weird but pleasent combination.

"I want you to get a marker and write 'Sister's slave' on your chest. Send me a picture. You know the consequences of what happens if you don't."

And just as I finish issuing my new order, the front door is pulled open and Dad announces his arrival. "Kids, we're home."

I shoot an urgent glance at Theo. "So what will it be? Should I start with showing them what you are up to?"

"Abby? Theo?", Mom asks from downstairs and without waiting for my brother's response I skip downstairs, running to wrap my arms around my parents in a thigh hug.

"I'm so glad you guys got home! I have so many things to share!"

As soon as I get near her bedroom door, she storms out and shove me hard on my chest, causing me to stumble backwards and try to hide my erected cock. As she threatens to ruin my life because I forgot to call her "Queen", I'm left with no choice but to obey.

While she distracts our parents, I go to my bedroom and try to calm down, but it's impossible. I'm way too aroused for having been reprimanded naked, by my own sister.

I plan to do her order quickly. So then, I can go into the shower to take off the writing. I take a blue marker and follow Abby's order. I don't want to make an error, nor mess the bodywriting, as to not give Abby's an excuse to punish me even more, so I take my time to write it on my chest properly. Then, I sit on my bed and take a picture of my chest. Still entirely naked, I use this opportunity to caress myself a little.

It's so naughty, I have never taken a nude selfie before. I take a look at the pic. "It's nice." We can see most of my abs, the bodywriting, a bit of my pubic hair and a part of one thigh and buttocks sitting on the bed. I don't dare to put my cock on the pic, cause she didn't ask me. I hope it will be ok.

Then I send to her the pic, with the message "I'm sorry my Queen, for my lack of respect. Please accept my apology." It's so humiliating. For some seconds, as I click on send button, I have the impression to be entirely owned by my sister.

"The day is over, now that parents are at home, and I'm safe", I think. I breathe a long sigh and take my underpants. I hope that Abby is still with our parents, because I have to use the bathroom, and I don't want her near. I open carefully my door, being discreet as I rush to the bathroom to clean the bodywriting and take a long shower.

Theo rushes to his room as I stall our parents. I'm not evil enough to want them to see him naked in the staircase. After making small talk and telling them about my day, hiding the fact that I had caught my naked brother masturbating, I make my way back to my bedroom, where a unread text from Theo waits for me.
I open the picture to find that he did just as told, and, given the noise of running water, he must be washing it off right now. Hopefully, the ink won't go away so easily, but even if it does, now I got more blackmail material and photo evidence is all that really matters.

Taking advantage of the fact that he's showering I creep into his empty room, wondering what else I can find to keep him as my slave. "Maybe he has nudes photos of himself in his phone, I could use some more of those".

With this is mind, I step carefully to not make much noise nor to disturb his things and fiddle with his phone until it unlocks. I roll my eyes, he really should stop using the same password he use when he was seven.

I open the gallery and... "Jackpot", I whisper. I almost don't believe my eyes. A full collection of photos of girls in bikinis, zoomed in on their boobs and butts, likely screenshotted from theirs respective Instagram. I see a flaming red head that I assume to be his precious Emily and a few other girls I have seen him tagged in photos with. But then I see one of a night gown I recognize very well. "That's me!"

Realization hits me and take a photo of his phone, making sure to catch his distinctive phone case in the picture, as to have no doubt to who that nasty collection belongs to. I hear the shower being turned off and, a bit disturbed from my discovery, rush out of the room. "Does he find me sexy? He couldn't, could he?" Because the truth was that I had always thought of him as being super hot. If the feeling was mutual... "No, Abby, don't go there quite yet."

"Hey, Mom", I shout as I go back to the living room. "Wanna me to help with the dinner?" Cooking would be a great away to avoid thinking about Theo and my (and his) feelings. Expect he could maybe join me in the kitchen... I certaintily can think of some dares for him to complete while I make dinner...

"Sure, darling. But you don't need to, especially as you have already done the laundry like I asked", Mom replies, kissing my forehead and patting my hair. "Someone is al helpful today... What crazy expensive thing will you be asking for?" She jokes, referencing the fact that I only volunteer to help around the house when I want them to buy me something new.

"Nothing, maybe I just want do some favors for you. You know, be a good daughter and all that."

She laughs and we keep up with a cheerful banter until I see Theo at the top of the stairs. "Hey, I'm about to start cooking. Join me." To the casual observer, it might have sounded like a suggestion or an invitation, but he knows better than that. It was an order. And he already knew the consequences of not following them.

I manage to reach the bathroom without problem. I take off my underpants, start running the water and go under the shower. In order to erase my new title from my chest, I put soap all over it and use the washcloth to wash it. But the marker is very difficult to take off. I rub as much as I can, but nothing helps.

The result is not so good, my skin burns raw, red from the friction, and "sister's slave" still in place. I start to take care of the other part of my body, then come back and try to erase the writing again... but impossible. It doesn't work at all. I sigh and stop the shower, grabbing a towel and putting it around my chest. I get out, heading to my bedroom.

"Maybe Google can suggest a solution for me", I decide and pull up my phone to do a quick search. "Mmm. Here! Alcohol. It looks like a good solution. I might find some in the kitchen, I just need that and some tissue."

Still with my hair wat, I take a t-shirt and a short pants and go down the stairs to reach the kitchen, but find my sister instead. "Hey, I'm about to start cooking. Join me."
"Ah sure, my sister, to who I can't say no to." She looks more friendly this time, and since our parents are near, I suppose there's nothing to fear.

"Of course, I'm coming," I tell her.

Well, low chance to get alcohol right now to take off the writing. I will take care of this issue when everyone goes sleep tonight.

He follows me into the kitchen, still wet from the shower.

"What do you need me to do?", he asks, before realizing his mistake and correcting himself. "Err.. I mean... what do you need me to do, My Queen?"

I smile, pleased with him. He was starting to learn the new rules. "You can start chopping the vegetables, and I prepare the meat."

He nods and open the refrigerator to retrieve the items we will be using as I pick up the knives and cutting boards. We start to work side by side, he washing potatoes, carrots, onions and tomatoes while I chose which spices and herbs I will be using to season. Despite his task, I notice him stealing glances at my cleavage, which, in any other day, would have caused me to blush. "Today he will be the one doing the blushing."

Reaching for the meat hammer, I start the process of tenderizing the beef. "Do you wanna change?", I prop Theo. "I know you love beating some beat."

He quickly glances to the kitchen door, towards the living room. "Can we not do this right now?", he pleads and I clear my throat. "... My Queen. Our parents are right there."

I sigh. "We do this when I decide so. And I choose to do it now", I bring down the hammer full strength on the meat and the whole counter shakes a little. "Got it?"

"Yes, My Queen", he replies.

"Good. Now put a pot on the stove with some oil so I can start cooking", I order, waving him away. He drops his knife and goes do as I told. I wait the oil to heat up before dropping the beef inside and watch as it start searing.

"You know, if you like my body so much, you can just take a picture, they last longer", I say, after the tenth he glaces my way to stare at my body. Heat creeps into his cheeks and I laugh. "Oh, forget it. You already have the photos. I guess you just prefer to look at the real thing, don't you?"

"Ab-- My Queen, I can explain..."

"No", I walk up to him and snatch the carrot he is cutting from his hands. "No more explaining", I bite off the thin end of the carrot before handing it back to him. "Two choices: you can either shove this up your ass for the rest of the night or", I pause, grabbing the black pepper powder I had been handling earlier, "you can rub this on your balls. I really hope you pick the second, as it might help with your not so little problem", I add, gesticulating to his obvious erection. "So, slave, what's going to be? Either way, I want photo proof", I shrug, "got tired of being your unwilling model, now it's your time to go in front of the camera's."

"Not now... please! If you want some proof, I'll show you later, my Queen, when parents..."

She erases her smile and says with a serious voice. "Slave, don't dare to answer me anymore. Now you are going to take off your pants." I hesitate, and look behind me at the door, expressing the risk of getting caught by the parents. But she adds, still very seriously and looking at her phone. "Don't make me repeat myself." Then she turns back to return the piece of beef to the stove.

I'm scared and excited. I am trying to find any way to sort this out, but there is no option except to obey. She turns to me one more time. And I make the decision to do it and take my pants off entirely. "It's so humiliating to get naked in front of her."

"Good" she pushes my pants off with her feet. "On your back now, show me your ass and your cock." She stares intently into my eyes as if she looking for a trace of insubordination or hesitation.

I was hesitating, but I force myself to please her, and lean back on the floor, spread a little my legs, and bring my knee closer so my cock and ass are exposed to her.

She uses her feet, pushing my legs to spread them even more. "My slave needs some stretching."

It's so embarrassing and shameful to be in this position. The sight of me like this draws an evil smile on her face. "Finally, I want to see the carrot in ur ass. I'm giving you 30 seconds to stick that in your as. If after this time, the carrot isn't in, I will guess you prefer the pepper choice," she says after taking a look into my asshole. Then, she turns around to take care of the beef and reduce the heat. During this time, I'm doing my best to put the carrot inside me, but my hole is very tight and resists the intrusion.

She turns back, looks at me, and uses her phone. I'm guessing she is taking pictures but I don't really know. Then, she approaches me with an evil smile, as if I had failed a task, and she is enjoying it.

The pain was slowing down too much my progress. "It's too hard, my queen, 30 seconds only..."

"Tsk, what did I just say before? Shut up slave,” she takes my hand away from the carrot, squats down, and puts her knee against the carrot to push it deeper inside. The carrot was not too big, but I have never used my asshole. So when she pushes the carrot, it forces roughly my tight asshole. I feel the vegetable progressing in my ass, making my hole sore. "Slave, your time is up. Rub those peppers on your balls", she says grinning.

I look at her with a desperate gaze, hoping for compassion .But her only reaction is to wait for my decision. I hesitate, still too focused on the pain in my ass to think of anything else.

She looks at the top of my hard cock and raises her eyebrows as if I was defying her. Then, she sighs. "You don't want to rub? Fine, I'll do it myself. Just know that you have disappointed me, slave, and you deserve to be punished."

She starts spreading peppers on my hard head cock. That's very unpleasant, as a slight burning feeling begin. Then, with an evil smile, she presents me with a black peppercorn and puts it on my T-shirt. "Put that in your cock, slave"

"No? In my..? What do you mean?"

She answers me by pushing more the carrot in my ass with her knee. "Stupid slave, dare to answer me once again, and that carrot and peppercorn will go so deep into your body than you can't even imagine."

My asshole was already sore, and now, I feel the carrot even deeper inside. It feels like it's ripped apart. After such threat, I obey and try to slowly insert this black peppercorn into my urethra. Abby rises up and places a foot on my balls with a large smile. "Deeper," she commands.

As soon as I feel the pain of her pressure and pepper on my balls, I tighten my jaws and push the little balls of pepper deeper into my urethra. I had never put anything in my urethra either, and the peppercorn inside brings me a mix of horrible pain and pleasure.

"Stroke your cock, I'm sure you're just waiting for that," Abby says with such a satisfied smile.

It's true. I guess the view of my erected cock can't fool her. I see her bite her lip, and put one hand in her pants, while the second is still holding her phone.

I start stroking, and she slowly releases my balls from her feet, walks over to me, and begins to pull the hem of my t-shirt up to see if the body writing is still there. She uses the hand that she had slid down her panties, and she leaves a wet patch on my t-shirt.

"Open your slave mouth, and keep this until I give you permission to stop", she adds, then fully pulls my t-shirt off, revealing the body writing, and places a part of the hem in my mouth. I feel immediately a good taste, as her wet hand has soaked it.

I'm so excited, it's at such a new level of naughtiness and humiliation. The pleasure of stroking quickly increases as I watch her stripping my chest, using her phone, and putting back her hand down her pants.

"You look very good like that, too bad for you that you did not manage to erase the bodywriting." She puts her feet back on my balls and starts to squeeze them again. "Enjoy, slave, aim for your chest, and don't mess up the ground, or you will lick it." She slowly increases the pressure and directs my cock towards my own chest with the tops of her foot.

I lose myself in pleasure. The closer I'm to the edge, the more Abby squeezes my balls with her foot. I moan once... and cum all over my stomach. For a short while, it's a delicious explosion. Shame, pleasure, and pain made an incredible aphrodisiac mixture.

But soon, reality comes rushing back to me. From the first load on my stomach, I start to felt very ashamed. And the pleasure begins to disappear. I realize that Abby is still squeezing my balls, and I feel more and more the pain of the pepper on my balls, head of the cock, and urethra. I'm still stroking, slower, hoping to have some last delight, but each stroke is vain.

A second load came and gives me only frustration, the pain becoming more and more dominant. A third and last little load comes out, but this one is a flow of pure pain and shame, letting my cock dripping and very sore.

I'm sure Abby watched the whole ejaculation without missing any detail.
But, for now, I'm looking with stupor at how this orgasm ended so badly for me.

I caught it all on tape, my camera filming every second of his release. Having him under my feet gives me a rush of adrenaline, a feeling of power like I have never felt before. And that feeling goes straight to my pussy. It was possible the hottest thing I had ever seen. And although all I want to do is touch myself until I cum, I still have a dinner to prepare. I put the phone away and go finish the meal while he gets up from the floor and rushes to clean his chest.

"It's ready!", I announce as I give the final touch of the beef and vegetables.

Theo emerges from the bathroom, looking flushed and embarrassed and he looks away when I smile at him. I sit in front of him, at my Mom's side, like I usually do.

"It smells amazing, sweetie", Dad compliments as I serve him a piece.

"Thanks. But I can't take all the credit, Theo really helped," I say. "He is really good with the carrots", I add, throwing my brother a wink. He blushes even harder and set his fixed on the empty dish in front of him.

We eat as Dad talks about an annoying client in his work and Mom enthusiastically speak about the fair opening tomorrow, that we had planned to attend as a family.

"Do I have to go?", I ask, not wanting to spend most of the day walking around between different market stalls selling organic lettuce or whatever. I'd much rather go to the pool party at Brian's house. He was a bit older than me, already on college, and whenver he came home in the weekends, he threw the best parties. I had always wnated to go, and this time, when i actually got invited to, Mom decided that I couldn't.

She sighs. "Abby, it's a family event. And I know the only reason you want to skip is to go to that boy's party."

Theo's eyes goes wide. "Which boy?"

"None of your business, T", I reply.

"Brian Robberts", my Mom chimes in. My brother cocks his head, curious as to why I'd be associating with Brian. He had a bad reputation around town. "I bet they will be drinking. I don't want you to go to an unsupervised party."

I'm about to say it's unfair, that all my friends would be going, when a idea hits me. "What if Theo went with me? To keep an eye on me. I could have fun with my friends, but there would be someone there to ensure things don't get out of control." I pout my lips, pleading to my parents. "Pretty please!"

My Dad sigh, relenting. "I knew you wanted something out of this dinner", he says with a smile. "As long as Theo is willing to go with you, I guess you can go. But, no drinking. And don't talk with older guys, stay with your friends."

"Yes!", I cheer. "Theo will love to go, he and Brian were classmates, right? Besides, he loves a good pool party."

I look at my brother and he nods. "Yeah, I was planning on going on my own anyways. I can keep an eye on my que--", he coughs, "my sister."
