My SM routine with my perverted sister

Buzz buzz buzz! I woke up to a sharp vibrating sound. However the sound wasn't a cell phone ringing, and I didn't wake up to the sound. Based on the feeling, it would be the little toy tucked underneath me ...... My newly groggy brain was so stimulated the moment I woke up that it caused me to have a splitting headache right now, and the mix of pain and pleasure pulled my nerves into high gear all at once. The [indescribable] stopped after vibrating for just about a minute, and for a moment I felt relaxed, yet somewhat unfulfilled. It was only after the stimulation stopped that I began to feel my condition. There was a tight constriction coming from all over my body, both legs were tightly together without a single gap, even my big toes were tied together. The upper half of the body could feel the rope binding everywhere, especially the chest and lower part, which was strangled by the rope, and there would be a strong friction sensation even if it moved a little bit. Hands were tied behind her back in a W position, and even her big arms were tightly attached to her back by the ropes, so she couldn't move at all. The only place within reach was a rope stick in the middle of my back, a rope connecting my wrists to the rope around my neck, so that whenever I struggled, I would pull on the rope around my neck, resulting in strangulation and not being able to breathe. After roughly understanding my situation, I silently sighed in my mind and completely gave up on the idea of breaking free, only to obediently wait for her to come and untie myself. "Oooh ......" Without much thought, there was definitely no escape from my mouth, which was filled to the brim with something soft, guessing that it was probably her stockings, which had become more and more swollen due to my drooling, stuffing every corner of my mouth with a bit of a gag. Something like duct tape was tightly attached to the outside to prevent me from spitting the contents of my mouth out. On the outermost part I could feel another layer of silk fabric wrapped around the entire lower half of my face, and several layers of wrapping allowed me to make a sound as thin as a mosquito's voice. Oh, I haven't introduced myself yet. My name is Ye Yu, I'm currently still in school, I'm in the top of my class, and I'm a lively and cheerful person. I am very confident in my looks, soft long hair, clear bright eyes, small delicate nose, delicate cherry mouth, all show the wonderful style of this age girl. It is a pity ...... that my height is only 155, and my breasts are also flat, and it is also a frequent thing to be recognized as an elementary school student outside. I am fifteen years old eh! But I'm sure it will develop later. Probably. That "she" is my sister, called Ye Jin, is now working in an international enterprise, the salary to maintain the two people living is not a problem, not to mention there are parents to give the living expenses. My parents work abroad all year round, and because of our strong abilities, they are very relieved that we are living on our own. In these many conditions, life is very nourishing and very free, there is not too much pressure of life. My sister's looks are very similar to mine, and dyed her hair brown, and naturally looks good, very mature woman's beauty. And her body is too much better than me, front and back, dimpled, height reached 170, pull out are directly can be a model of the kind. Only a pity that ...... is a pervert. If not a pervert, I wouldn't have been tied to the bed by her. Although I am also a pervert, otherwise I would not be obedient every day to let her tie up ...... I still remember that it was a warm and balmy afternoon, I sat paralyzed in front of the computer as usual, browsing through the pictures of my favorite rope art with joy. Like rope art is my little secret, this kind of not into the elegant and vulgar hobby is of course did not tell anyone, I also has been a person secretly like. Until the next few seconds after that time, my secret was no longer a secret. My sister burst into my room without warning and immediately questioned me about what I was looking at, as if it was premeditated. Naturally, I was so nervous that my mind went blank and I stammered, not knowing what to say. Then ......

My sister walked outside and then returned to my room with a box of cake and a glass of water. After she put the cake on the nightstand, she once again picked me up on her lap and began to undo the restraints on my mouth. First the stockings that were several layers around, then the tape that was stuck to my mouth, it hurt my skin a little when I tore it off, but I had to put up with it. Finally my sister stuck two fingers into my mouth, and with a gentle squeeze, pulled out a large mass of stockings that had long been soaked in my saliva. "Ha~~" I breathed a long sigh of relief when my mouth was finally free, and greedily breathed in the unimpeded fresh air. "Incidentally, this mass of stockings is the one I wore yesterday." My sister suddenly said with a bad smile. I knew it! "Hmph!" I huffed and rolled my head to the side, fully expressing my anger. My sister at that moment picked up the glass of water she had just brought in and took a sip. Just as I was wondering why she didn't give me a drink, she suddenly cupped my face in her hands and turned my face to her, then she kissed me directly on the lips. I felt a stream of manna flow into my mouth, my mouth that had been stuffed for too long had long been thirsty, I didn't think twice and drank all the water that flowed into my mouth. When all the water in my sister's mouth came into my mouth, she obviously wasn't ready to let go of me, and stuck out her tongue right through my mouth, and I didn't resist, letting her tongue wreak havoc in my mouth, and both of our lips were also biting each other tightly, and moving slightly from time to time. I closed my eyes tightly with some difficulty, but I still cooperated with my sister's movements, opening my teeth and letting her have her way. Because I also quite like this. After lingering for a long time, my sister finally let go of the hand that was cupping my chin and also retracted her own tongue. "Cough ha, ha ......" Because of the long time being occupied by my sister's mouth, my breathing was very difficult, and now I was finally liberated. Sister's tongue kiss really is a bit unbearable no matter how many times it comes ...... "Thanks for the hospitality." Sister licked her lips with great enjoyment, showing her charming demeanor, "Next, it's time to give Xiao Yu a reward oh." Sister unwrapped the cake, then dug a spoon into it, brought it to my mouth, and said, "Here, ah~" It's like feeding a little kid. "Ah~" But I obediently did as I was told, I couldn't help it, I couldn't use my hands now, so I had to let her feed me. The cake brought me enjoyment on the other hand, the soft sweet flavor increased my appetite, my spirit was lifted with it, and under my sister's feeding, I quickly ate the cake. I licked my lips with great satisfaction, an innocent smile on my face. Instead of feeding me water from her mouth this time, my sister brought the quilt to my mouth. I gulped down the water with a few gulps. The water washed the cake out of my mouth and made me feel very refreshed. After eating and drinking, I said to my sister, "Sister, it's time to let me go, it's been so long ......". Not waiting for me to finish, I don't know where she pulled out a mouth ball without saying a word and stuffed it into my mouth, and then very quickly in the back of my head to fasten, completely not give me time to spit it out. Haven't you had enough ...... My sister climbed onto the bed and clamped her legs around my bound lower body, then wrapped her arms around me and buried me deep in her massive [indescribable]. "Just a little while longer, a little while longer ......," my sister tenderly whispered in my ear, the hot breath she exhaled tickling my ear. "Well." Really can't do anything with this perverted sister.

My sister did intend to be ruthless this time, and took out another pair of nipple clamps, attached by a chain, which she then clamped mercilessly on my pink buds. "Hiss, that hurts, sis." The pain from the nipple clamps made me squint one eye. "That's how you know it hurts? There's more to come later." Sister said cruelly. There's more! I felt chills down my spine after hearing my sister's words, and now I very much regret tying her up yesterday. Ugh, who asked me to mess with her for nothing. This time, my sister didn't look like she wanted to gag me multiple times, and took out a circular cotter, and I obediently opened my mouth and allowed my sister to put the cotter on me. The cotter caught my teeth, preventing me from closing my mouth, and my mouth felt cold and metallic. "Ah ......" was the only thing I could do as my mouth was left open by the cotter, but I could only "ah ah ah" helplessly. My sister suddenly pulled out another nipple clamp with a chain, only this one wasn't used on my [indescribable], but on my tongue. She stuck her fingers in my mouth, pinched my tongue and pulled it straight out, then clamped it with the clip and attached the chain behind the clip to the chains of the two breast clamps on my chest. The tongue that was held tightly by the clamps could only dangle, because it was attached to the breast clips and the chains were short, there was no way to retract it back into my mouth, and retracting my tongue would have tugged on the buds. "Ahhh." It was really uncomfortable to have the tongue exposed to the air for a long time, and this look of sticking out the tongue was too humiliating. It's been a while since I put on the cotter, and the saliva that has accumulated in my mouth is getting bigger and bigger, finally overflowing at this moment, running down from the corner of my mouth and dripping down on my young breasts. My sister observed me for a moment, nodded in satisfaction, and helped me up from the bed, leading me over to the window with the intention of continuing to apply her equipment to me. I still had a good length of rope behind me at my wrists, and I seemed to know now what it was going to be used for ...... My sister threw the rope attached behind me upwards, through the clothesline, and pulled it down again, and then she walked away with that end of the rope so far that it was tugging at my wrists, causing them to be bound tighter and tighter, and I had to be forced to stand on tiptoe to get the pressure on my wrists to relax a little. My sister went all the way to the bed and looped the end of the rope around the foot of the bed several times and then tied it in a dead knot so that I was hanging securely from the ceiling. The amount of force my feet needed to use after being on my tiptoes was instantly greater, and my feet were now trembling a little, but once I lowered my toes, the rope would pull dead tight on my wrists, and that would hurt even more, so I had to stay on my tiptoes the whole time. My sister looked at me with satisfaction at this difficult and pitiful look, without the least bit of pity, and then took out another bundle of rope. No way! This is too cruel, I'm already so pitiful eh. My sister folded my left leg and tied it up with a rope, and then she took out another rope, connecting my knee to my waist, so that I could only do the golden chicken stand position. After making this position naked, my bottom hole opened up and the two lips and part of my inner channel were completely exposed to the air. Shame was abnormally high while at the same time the masochistic desire made me more and more aroused, sensitivity skyrocketed, and in no time the crystal clear liquid flowed out from below, flowing to the roots of my thighs Sister came over, tilted her head to look at my bottom, and said in mock surprise: "Ya, what is this. The little bitch is so wet so quickly ah?"

"Hee hee, that's a much cuter look." My sister took out a couple of ropes and tied a graceful tortoise shell bondage to my body. Then she didn't think it was enough, she tied the diamond-shaped chest bondage for me, making my upper body densely wrapped all over my body, good thing it wasn't the kind of tightness that strangles into my flesh, after all, my sister also considered the time of the trip. Then I put on two white stockings, while my sister tied two rings of rope on my white silk thighs, the rope circle also vertically wrapped around a few times as a fixed, so that I can only walk with small steps. After wearing these intimate attire, it is definitely necessary to have other clothes for camouflage. My sister put a short-sleeved sailor suit top on me, and added a black jacket with a hood on the outside, which covered my tightly tied up shibari body very well, but the skirt she put on me was very short, and if the hems flipped up slightly, onlookers would still be able to see the ropes on my thighs very well, so I still had to move carefully. "Open your mouth, ah ......" my sister took a ball of cloth and brought it to my mouth. "Ah ......" I dutifully opened my mouth too, and closed my eyes. A softness entered my mouth and gradually filled every corner of my mouth and blocked my right to make a sound. Then my sister tore a few pieces of tape and stuck them over my mouth until the lower half of my face was covered under the tape, making it impossible for me to spit out the cloth. Finally she put a gag on me to hide my duct-taped mouth, but breathing was getting a little harder. "Oooh ......" gagging still feels so intoxicating. My sister looked down at me, a work of art that belonged to her, and who knew what kind of astringent look such a cute girl with a normal appearance was hiding under her clothes? My sister herself was wearing a strapless tight top with a silk shawl, and the lower half of her body was covered in ultra-short hot pants and black stockings, looking not to mention how sexy it was, making me degrade myself to be abused by her. She grabbed her suitcase and a satchel, and I picked up a backpack, intending to make it official. Instead of wearing heels, we both wore regular sneakers since we were traveling a lot. When we were almost at the door, my sister suddenly pulled a leather collar with a chain out of nowhere, and without asking my opinion, put it around my neck and locked it. "Oooooh??" I felt a little scared, it was too obvious! "It's okay la, there's not many people this early in the morning, it's a short walk to the garage, don't worry." Looking at my sister's evilly smiling face, I had no choice but to acquiesce. My sister pulled the chain, slightly pulling my neck, and happily shouted, "Let's go, go on a trip!" All kinds of body movement is restricted a lot, walking can only be careful, but out of the house, but the body is tightly bound feeling so exciting ah. Luckily, from the house to the garage, did not bump into people, we also smoothly put the luggage in the trunk of the car, and then get into the car. After sitting in the car, I was relieved that I could rest for a while next. But my sister saw me and said wistfully, "It's so unfair that I have to drive all the time and you have nothing to do." So what do you want. I looked at her speechlessly, unable to say anything even if I wanted to. "How about, you find me some fun!" My sister suddenly took out a remote control and waved it in front of my eyes. That's when I remembered that there were five toys placed on my body to come. Alas, it looked like there would be no rest for a few hours. Sister took out a handcuffs, through the gap between the headrest and the back of the chair, so that the chain stuck in the middle, and then locked my hands into the handcuffs, so I can only keep my hands above my head position, the tightly bound body can only be at her mercy. Then my sister fastened my seatbelt, but she deliberately fastened it extra tight, strangling me between my breasts, once again making them a little bigger. Combined with the ropes tied under my clothes, the double constriction made me horny. "Oooh ......" It was like I was one with the co-pilot, being tightly restrained and unable to move, it had that movie feeling of kidnapping a teenage girl and transporting her somewhere else oh so helpless and pathetic. Sister also fastened the seatbelt, looking at her large breasts strangled by the seatbelt, I can not help but produce a few moments of jealousy, hands want to go up to squeeze a few handfuls of hard, but I forgot my hands are locked in the top of the head. With the engine started, our trip had officially begun. ......

I knocked on the door, and a cold, familiar female voice immediately came from inside, "Come in." It seems my sister is really getting into character. I pushed open the door and cautiously walked in, only to see my sister sitting on a chair, dressed in a cool, black long dress. She was crossing her legs in black stockings, propping her head, exuding an air of cold, arrogant beauty. As if she didn't know me, my sister spoke indifferently, "Don't say anything. Take off all your clothes." This domineering sister was nothing like her usual sometimes gentle, sometimes playful self. It was as if she was deliberately creating a distance to help me adapt to my role as a slave pet as quickly as possible. And I didn't dislike it at all; I loved it. This look of disdain and condescending tone made my masochistic soul burn fiercely, and I was conquered in an instant. I slowly opened my mouth, my voice trembling slightly, "Yes, yes, Master." My sister suddenly thought of something and said, "Oh, right. Since you're a pet, you shouldn't speak human language. Except for the commands I give you, you can only meow at other times." I cooperated fully, letting out a somewhat shy "Meow," and then began to undress. Soon, my incredibly cute school uniform was shed, revealing a slightly immature yet extremely lewd fair body. This is what a pet should look like. Seeing my naked body, my sister remained unmoved, only saying, "Fold them neatly, place them with the contract, and then kneel. Kneel in the way I like." I knew what kind of kneeling my sister liked – the Japanese dogeza, which was difficult but incredibly shameful. After doing it, I wouldn't be able to hold my head up again. So, I folded my sailor uniform and skirt, then neatly arranged my bra, panties, and socks, placing them with the contract. The contract read, "The lewd and cheap slave Ye Yu voluntarily becomes Ye Jin's lifelong pet, obeying only the master's commands and never betraying her
