Slave 317
The book originated from an idea that Sven U. sent me via email. He wished for a story about two half-sisters. For the plot, he gave me complete freedom, and I spent a while thinking about how to guide the two characters. Once again, chance came to my aid, as a woman in my circle of acquaintances was also clashing with her sister for years. Together with her, some ideas emerged that I then picked up and refined slightly.
This led to the story set in an old castle somewhere in the wilderness and the backstory of the two protagonists. I also drew inspiration from stories told by a friend who described a real institution in Europe. Somewhere in the Czech Republic, there's supposedly a residence run by dominatrices that is visited by single men for several weeks on vacation. Still, most of the ideas came from my own mind. Honestly, I never expected this story would achieve such lasting success. It's one of my most successful books, and quite a few readers have requested a continuation, which I then wrote as *Slave 317: The Training*.
Chapter 1
Like a wild one, I hammered against the bathroom door in my parents‹ house early in the morning. For what felt like hours, my stupid sister had been in the bathroom, even though she didn’t have to get up at all. That bitch was doing it on purpose. I had to go to my lecture at the university, and my damn sister was blocking me once again. For years, we’d been constantly at each other’s throats. I hated her, and she hated me. Actually, she was my half-sister. We had the same father but different mothers. Unfortunately, only hers was still alive, while mine had been lying in the cemetery for many years. She had died in an accident, and my father had then decided to marry his affair and give me a half-sister of the same age whom I couldn’t stand to death. However, the feeling was mutual. Not only my father but also my stepmother regretted this marriage every single day. Since I had to live under one roof with Jennifer, we were at war.
She was the exact opposite of me. I loved art, music, and dance; she, on the other hand, dealt with noise, vampires, and other demons. While I enjoyed the calm sounds of many pop songs, her music—or what she called music—was simply unmelodious noise. Officially, it was called Death Metal, but for normal ears, it was just unbearable racket and had almost nothing to do with music at all. The two of us alone in one place could really only end in murder and manslaughter. She spent hours in the bathroom that morning. She had been out all night partying, while I had sat over my books the previous evening so I could keep up in the lecture today. Only access to the bathroom was denied to me because Jennifer had locked herself in there long before I got out of bed. Probably, the stupid slut had simply fallen asleep on the throne and was sleeping off her hangover.
It drove me crazy. I had to go to the toilet and, of course, take a shower to awaken my spirits before I could go to my lecture. My black-haired half-sister with the ugly short haircut occupied the only bathroom in the house, and I drummed against the door like the last madwoman, which once again brought my stepmother into play, causing her to appear behind me in the hallway. She yelled at me, »Damn it, Nicole, can’t you two goats get along at least early in the morning? This is unbearable.«
»I’ll kill the slut! She constantly fucks her way across the city, drinks alcohol like water, comes home only in the early morning, and then occupies the only bathroom in this shit house. I urgently need to pee, shower, and then go to the lecture so I don’t end up in the gutter like her. Can’t or won’t any of you idiots understand that?« I screamed back.
My stepmother knocked softly on the bathroom door and said much quieter, »Jenni, come out so the crazy one here disappears for a few hours at least.«
Suddenly, something happened behind the door, and we heard the key. The door opened very slowly, and my half-sister appeared in a deep black, semi-transparent dress with tear-stained eyes in the doorway. Without a word of apology, she stomped off and locked herself in her room. That woman got extremely on my ovaries. She locks herself in the bathroom because some bum with torn pants didn’t necessarily feel like getting a venereal disease and therefore didn’t want to jump into bed with her, while other normal people like me had to go to university. My stepmother disappeared back into the bedroom; the door slammed behind her, and I was finally alone. I urgently needed to earn enough money for a tiny dump so I could have my peace. My parental home was the purest hotel for complete failures and casual whores. Unfortunately, the money I earned from my job in a bar was just enough for tuition fees. Almost nothing was left for living.
To save time, I slipped out of my clothes, jumped under the shower, and emptied my overflowing bladder right under the warm water. Due to the waiting time, I was already extremely late and had to hurry a lot not to be late for university, where I was meeting my friend Diana. The shower did me good and drove the sleep from my eyes. Unfortunately, because of the damn witch disguised as my half-sister Jennifer, I had much less time to feel the hot water on my body. The only purpose of her miserable life seemed to be to sabotage mine. I was apparently the only one in my family who wanted to make something of herself. Jennifer was the Antichrist, my stepmother a boozy whore, and my father the last bum who stood behind the cash register at a gas station. Because my half-sister once again couldn’t find a failure to stuff her holes, I was way too late again.
As soon as I was freshly dressed, I had to run to the bus stop. Here in the suburbs, the bus only ran every half hour, and if I had to take the next one, I would be late not only for my appointment but also for the lecture. As a little girl, I dreamed of a prince waiting at my door with a snow-white horse to take me to his castle. Admittedly, today I dreamed more of the princess, but I still wanted the horse and the castle. What reality granted me was an unshaven old bus driver with a stinking poison-green painted bus that I had to share with an entire comprehensive school. My castle was then the university, where a disgustingly smelling professor awaited me, whose only bright spot in life was probably the pill box.
Diana was already waiting for me when I finally got off the bus. She greeted me with a small hug and smiled, »You look terribly worn out, Nicole. What’s wrong?«
»Better not ask. Try getting up in the morning and not being able to get into the bathroom because your half-sister wasn’t filled again and is crying on the shitter because of it.«
My fellow student couldn’t stop being amazed. It was quite funny that a 22-year-old adult woman was crying on the toilet again because she hadn’t found anyone to stuff her hole in one night. Since Jennifer was 16 years old, unlike me, she rarely slept at home. Mostly, she went out in the evening, and you didn’t see her at least until the next morning. Sometimes she was gone for several days. For me, those were the most relaxed days ever. When my half-sister wasn’t at home, basically only my stepmother was left to get on my nerves. Apart from the times when she was on bed tour again. Then I had peace because only in the evening my father and the slut were at home, but they mostly left me alone.
Diana was something like the calm pole in my life for me. I had known her forever, and we weren’t really that different. Okay, unlike me, she was into men and had had her boyfriend by her side for several years, but I got along well with Tom. They both knew that I was into my own gender, and that was never a problem. My friend wasn’t relationship material for me anyway. We got along splendidly, could laugh about the same crap, and spent a lot of free time together as a trio. Her boyfriend Tom had also become a good friend to me.
We strolled cheerfully into the lecture and listened to all the nonsense that a professor threw at us. During the lecture, we also had nice conversations again and again before meeting her boyfriend Tom in the cafeteria for lunch break. For me, those were the most beautiful times of the day. There I was with friends, had my fun, and also the necessary peace. At home, I preferred to spend as little time as possible if it was avoidable. Somehow, these times passed much too quickly. In the late afternoon, I arrived home again, unlocked my room, and sat down at my computer. That’s where the learning continued for me, apart from the disgusting noise coming from my half-sister’s room. She always listened to the crap she called music at a volume that made your ears bleed, but that day she was even louder than usual. How was one supposed to find concentration like that? Angrily, I got up, bothered myself into the lion’s den, and yanked the plug of her music system out of the socket. Jennifer was still lying crying on the bed and didn’t even realize at first what had just happened. Finally, there was peace in the house.
Unfortunately, this peace lasted only a few minutes until it started again as loud as before. If you won’t listen, you have to experience it. I got up again, stormed into her room, and threw the entire system out of the cabinet. Angry, I stood in front of her bed and yelled at her, »Turn that shit down or leave it off altogether. I don’t feel like being disturbed every fucking day by you, you dirty cunt, while studying. If you turn that shit on again and it throws me out of my chair, I’ll rip off your ugly head and throw it onto the street!«
Without another word, I ran out of the room, slammed the door behind me, and sat down in my chair. She seemed to have understood, because until night, not a sound was heard from her anymore. Finally, I could concentrate on my material for studies. The next morning, there was finally peace. My hated sister was still lying in her stinking den, my father was at work, and my stepmother was just leaving the house when I went into the bathroom and prepared myself for the day. I enjoyed this wonderful peace almost more than the hot water of the shower. To relax further, I began to stroke myself, directed the pounding water from the showerhead onto my clit, and treated myself to a wonderful orgasm. The sensation built slowly at first, the warm streams teasing my sensitive skin, sending waves of pleasure rippling through my body. My fingers traced circles around my folds, dipping in and out as the water intensified the pressure, making my breaths come in short gasps. The steam filled the room, heightening the intimacy of the moment, my mind wandering to soft, feminine curves and gentle touches that made my core tighten. As the climax approached, my legs trembled, and I leaned against the tiled wall, letting the ecstasy wash over me in shuddering waves, leaving me breathless and momentarily free from the world’s chaos. For the first time, the day started to my liking, though that wouldn’t last long.
When I came into the kitchen, I discovered a note on the table in my father’s handwriting. It said, »We’re going on vacation for three weeks starting tonight, and you two are staying home alone. At least leave the house standing if you have to go at each other’s throats. We’ll leave a little money on the table. Divide it up until we’re back.«
Well, wonderful. Three whole weeks alone at home with that shrew. That was already an automatic declaration of war. Couldn’t they have taken that living corpse with them or dumped her somewhere in the world with concrete shoes in a harbor? That would have been the better alternative. But okay, in those three weeks, Jennifer would keep quiet; I’d make sure of that personally. Who was going to stop me? Certainly not that half-shirt that was my half-sister. If she was even at home and not fucking her way through the city again.
When I came back from university, the whole house was deserted, and I had my peace. Jennifer was probably out again, fucking half the city, and my stepmother and father had long since left. What could possibly make that day even better? The next day, I didn’t have to go to any lecture and only had to work in the evening, which meant for me that I could finally sleep in and didn’t have to deal with anyone I couldn’t stand anyway. Three weeks of wonderful peace, apart from my half-sister, whom I hardly expected to be at home.
The next morning, everything felt somehow strange when I woke up. I opened my eyes, and it remained completely dark. Not even the clock on my alarm was visible until I realized that I couldn’t even move my arms or legs. What the hell? I was lying in my bed, and all I could still move was my head, but it provided no visual stimuli. Not even a sound was audible except my breathing. Once again, I tried to move, but neither my extremities nor my hips allowed any movement. The nerves in my arms reported to me that something was holding me at the wrists. It was the same at my ankles. I mustered all my strength, but only my fingers and toes could I move. Suddenly, I heard the voice of my hated half-sister right next to me, »Well, finally awake, you slut? I’m curious how you want to rip my head off without being able to move.«
»Untie me immediately, you stupid cunt«, I shouted, beside myself, and tugged at my bonds. At the same moment, I felt her fingers on my nipple, which felt like my half-sister was cutting it with a knife. But it was only her long fingernails mercilessly pinching the sensitive glandular tissue together. Completely calm, she replied, »You should be a bit nicer to me, Nicole. Otherwise, you’ll force me to hurt you. Besides, I don’t really care.«
»I advise you to better kill me. As soon as I can move again, you’ll definitely be done for«, I threatened her.
I heard her laugh before she cheerfully said, »It won’t be necessary to kill you. By tomorrow at the latest, you’ll do everything I say voluntarily and to my complete satisfaction. Otherwise, you’ll wish I would kill you to make the pain stop. However, I won’t do you that favor.«
As soon as she finished her statement, tears shot into my eyes, and my left nipple exploded in a huge fireball. As soon as I was somewhat back to myself, the same thing happened on the other side again. Once more, I heard Jennifer laughing evilly. The pain in my nipples didn’t subside at all. It still felt like they were burning, even though I could hear from her laughter that she was moving toward my door. How did that work? However, much worse was what she actually planned to do with me. But I only got the answer to that about an hour later, it felt like.
Chapter 2
After the eternal waiting period, she apparently came back fully loaded. She didn’t miss the opportunity to clear off my desk and place all sorts of things there. During the whole time, she didn’t say a word. I only heard her grinning and screamed at her as loud as I could. However, that didn’t bother her at all, and she waited completely calmly until I stopped my hate tirades against her. Only then did she laugh, »Scream as much as you want; that doesn’t interest me. Now you’re going to listen very carefully to what I tell you, then maybe something will occur to you. The day before yesterday evening, you sealed your own fate. You ran into my room twice and turned off my music. I won’t let you interrupt me in my grief. The point is, you’re now taking exactly the place that I lost, with all the consequences. That means you can say goodbye to your studies because you won’t finish them.«
Me not finishing my studies? What else did my half-sister dream about? Of course, I would finish my studies; she could do absolutely nothing against that. Let Jennifer just keep dreaming. However, she was far from done with her statements. There was still a lot to come. She spoke quite calmly, as if she had nothing to do with it, »When I let you sleep again, you’ve seen your room and all this crap here for the last time because when you wake up again, you won’t know where you are, and you certainly won’t find your way back. Mom and Dad don’t care where you are anyway. The rest don’t care about you either, except for the owl Diana and her fucker, but they’ll get a suitable letter from me.«
That was quite a blow for me at first. I still didn’t understand what she was actually planning, but I would only find out when it was already too late anyway. The next surprise for me was when she finally removed the blindfold she had attached there. My half-sister wasn’t standing in front of me in her typical black clothes like at a cemetery, but in red and black leather. She looked completely changed. I had never seen her like that before. It didn’t look that bad on her; I just wondered why she otherwise walked around as if she came from a funeral. Then I finally saw what she had done to me and what prevented me from any movement. Tight plastic straps were hanging everywhere on me. My arms and legs were stuck in tight leather straps connected via a heavy steel ring to the straps. Even over my hips ran such a strap, pressing me onto my bed. Like on a cross, I lay on my bed and could only move my head. The next glance fell on my bust, and I couldn’t believe what I saw there. In both my nipples hung a needle, wobbling from my breathing.
But something wasn’t right. The clock next to my bed already showed shortly after 2 p.m. in the afternoon. I could hardly have slept that long, and even more incomprehensible was why I didn’t notice Jennifer tying me up. At the latest, I should have woken up then. I had a pretty light sleep and woke up even when someone opened my door. But my half-sister provided the explanation, grinning, »Someone’s surprised. Yes, it’s really that late, but you slept nicely with a little help. A bit of gas was enough to take you out of the game for a few hours. After that, I just had to wait until you came to again. By the way, I thought it was nice of you to sleep only in panties. That makes it a bit easier now.«
She took a huge knife from my desk, held it threateningly in front of my eyes, and cut through the straps on both sides of my hips under my loud protest. She grabbed the front part and simply pulled it down away. I lay completely naked on my bed, and my half-sister held my cut panties like a cheap trophy in the air. Her next sentence almost took my breath away, »What do I see there? What is that jungle supposed to represent? We can’t leave it like that; I don’t accept that with slaves.«
Slaves? What kind of movie had I landed in here? I wasn’t a slave, and certainly not my hated half-sister’s. She put the knife back on my desk and instead took a longer tweezers in her hand. With that, she came to my bed, sat down next to me, and showed me an evil laugh. Very slowly, she stretched her hand with the tool toward my pubic mound, grabbed a long pubic hair with the tweezers, and pulled it up. She tormented me by repeatedly pulling on it until it hurt and laughing at it.
»A little fun has to be allowed before we pull it out, right?« she asked. Without waiting for an answer, she simply ripped it out and held it in front of my nose. »Open your mouth«, she demanded. I didn’t dream of allowing her this humiliation and demonstratively pressed my lips together. Jennifer started laughing and simply pressed on the needle stuck in my nipple. Immediately, a wretched pain shot through me, and I screamed. Exactly at the moment when I had to take a breath again, she dropped the pubic hair into my mouth. Instead of screaming, I started coughing, and my half-sister laughed at me. Then she asked, »Do you really want to repeat this game the whole time, Nicole? I’ll drag this out until next week; I don’t care.«
I had completely underestimated my half-sister all these years. All the time, I thought she was completely stupid and too dumb to piss a hole in the snow. Apparently, she wasn’t really, because she seemed to know extremely well what she was doing to me. »So? What should it be now? Mouth open, or I’ll make sure you open it automatically.«
»Fuck you, you stupid cunt«, I screamed at her. »You can wait for that until doomsday!«
Jennifer didn’t answer me. She simply got up, placed her tweezers on my chest, and disappeared to the desk. After a short grab for a strange pliers, she came back and sat down next to me on my bed again. While one of her hands pressed one of the needles in my nipple deeper and deeper, causing me incredible pain that made me roar loudly, she casually stuck the pliers into my mouth. Then she left the needle alone and waited until my screaming slowly subsided. I had tears in my eyes; every muscle in my body was tense and just waiting for a small chance to escape. Without me being able to defend against it, she squeezed the pliers together, and my mouth opened as if by magic. She hooked something on the pliers, and it was no longer possible for me to close my lips. Grinning, she took the tweezers again and started working on my pubic hairs again. Enjoyably, she ripped many of them out and stuffed them into my mouth.
I had no other choice but to leave them there, but Jennifer had just started with the meannesses. With a small water bottle, she dripped only a tiny sip into my mouth each time, and I simply had to swallow. Whether I wanted to or not played no role. Whistling cheerfully, she plucked more and more of my hairs out. When I thought I might get used to the pain and not moan so loudly anymore, Jennifer changed position closer and closer to my labia. To hurt me even more, she no longer grabbed the hairs but directly my lips and simply pulled on them.
The sensation was excruciating, each tug sending sharp, burning waves through my sensitive flesh, amplifying the humiliation as my body betrayed me with involuntary twitches. My mind raced with conflicting emotions—rage at her dominance, a twisted undercurrent of arousal from the pain mixing with vulnerability, my core clenching despite the agony. I hated how the exposure made me feel, naked and at her mercy, the air cool against my heated skin, every pull heightening the erotic torment in a way I couldn’t ignore. My hatred for my half-sister grew with every second. If I could just move my arms a little, I would simply break her nose, free myself, and then leisurely gut her. Unfortunately, I was strapped so tightly to my bed that I couldn’t defend myself at all. But it got even worse because my bladder started to press terribly. I urgently needed to get rid of something, but how was I supposed to do that? Jennifer seemed to notice that, smiled at me, and asked quite cheerfully, »Well, does someone need to go?«
Since I couldn’t speak with the pliers in my mouth, I nodded shyly instead. That triggered a very broad laugh on her face. To make it even harder for me, she pressed her hand directly on my bladder as she stood up and once again walked back to the desk. But instead of loosening my bonds, she took a moment and strolled out of my room. A few minutes later, she came back with a strange plastic bag that had a small tube attached. Cheerfully, she explained to me, »I’ve been waiting for that. The catheter will give you a lot of fun when inserting it. The best part is the wonderful valve. Instead of getting something out, we’ll just push a little more in. You’ll love it.«
She simply stuck the tube into the water bottle and asked me, »How much should we push in? Should we take a hundred or two hundred milliliters?« only to answer immediately afterward, »Oh, since it’s only you, slut, we’ll just take two hundred. It’ll fit.« With that, she drew the amount into the bag, checked the printed scale again, and said laughing, »Oops. Now it’s a bit more, but the quarter liter will go in too.«
I yanked at my bonds, shook my head, and made noises like a rutting stag to stop her. Contrary to my hope that it would stop her, she only asked briefly, »Is it perhaps too little for you?« Of course, it was the exact opposite. According to my anatomical knowledge, the bladder holds something around half a liter, but no more. Since it was already pressing, it had to be more than half full anyway. So what she intended would make it burst. As if she had practiced this a thousand times, she spread my labia with her fingers and placed the catheter at my urethra. Then she grinned, »Relax nicely, Nicole; I’m not careful at all. Promised.«
I screamed with all my lungs as she simply rammed the tube into the tight entrance and pushed it further and further into me. The intrusion was brutal, a searing burn that radiated deep inside, my muscles clenching futilely around the invading tube, tears streaming down my face as the violation stirred a dark, unwanted heat in my core. Every inch felt like fire, the pressure building not just physically but erotically, my body responding with a shameful wetness despite the pain, heightening the intensity of the humiliation. But the worst was yet to come. When she arrived in my bladder with it, she set the valve and squeezed the bag. The pressure inside me took on epic proportions. Never before had I needed to go so urgently, but Jennifer only challenged it more by pressing even more into me. Like a slaughtered pig, I squealed on my mattress, tugged at my bonds in the hope they would somehow give way, but it helped nothing against my half-sister. She smiled more and more, pressed a little more into me, and then asked, »Well, isn’t that nice?«
It was anything but that, but I simply couldn’t make her understand. I felt like bursting and croaking torn open in my bed. With a really nasty grin, she closed the valve again, placed the bag directly on my bladder, and left me pumped up for a whole while. I just wanted to die so this misery would end, but that was completely indifferent to my half-sister. Why did this damn cunt have to torment me like this? Couldn’t she have simply slit my carotid artery with the knife and then watch me bleed out? That would at least have been somewhat humane, and I would know that it would be over shortly after.
Only after half an eternity did she come back, holding a plate in her hand and slurping some spaghetti enjoyably. Hunger had long since passed me by. I urgently needed to go to the toilet because a water bomb was waiting for detonation in my lower abdomen, and my lower jaw hurt. Between my teeth, that stupid pliers was still clamped, reliably preventing the closing of my mouth. Like the innocence from the country, she sat down on my chair, crossed her legs, and spooned the noodles contentedly. Then she started a monologue, »You’ve always played mean jokes on me and thought you were something better. The great student Nicole and her sister, the dummy Jennifer. While you were pushing a quiet ball at your university and only did something occasionally that would never get you further, I worked and earned quite a lot. It was more or less indifferent to me all the time, but the day before yesterday, fun was over. I was deadly unhappy because I lost someone very important in my life. Instead of letting me grieve, you whined and hurt me even more with it. But you know what? I’m making your shit life hell on earth now until I allow you to step down sometime. Look forward to many years in which I’ll enjoy tormenting you whenever and however I want.«
I couldn’t answer anyway, so I closed my eyes and just let her babble. Why should I listen to her anymore? It didn’t interest me what she had to tell. She could tell it to the mirror in the bathroom if she liked hearing herself talk so much. All I needed was a tiny chance, and I would knock this beanpole out of her shoes and simply eliminate her. A small cut would suffice. Physically, this fury was far inferior to me. Jennifer was about as tall as me with my 175 cm height but weighed just around 60 kilograms. I brought it to a live weight of 85 kilograms. Something like my half-sister I could devour for breakfast with a bit of mustard. All I needed for that was a very small opportunity, and I wouldn’t hesitate to take her out. She couldn’t do anything against that, and she knew it too. Sooner or later, she had to untie me, and then my chance would come. I just had to wait, and I had enough time. Just wait, Jennifer!
