When my best friend became my stepmother, I became her pet.

Zi Xi got out of bed and ordered me to lie down. Then, she began to take out items from the box, mostly shiny black leather goods. Zi Xi first covered my entire body with baby powder, then picked up a black latex suit and helped me put it on. She reached her hands under the suit from my back, and since the suit was open in the front and back, Zi Xi began to adjust the position of my breasts. I let out a shy gasp of shame. After I was dressed, she zipped it up and locked it with a small padlock. Then Zi Xi began to put on a corset for me. My waist was already very slender, and after Zi Xi put it on, she pulled it hard a few times. Finding that it couldn't be tightened any further, she fastened it with a restraint strap. Next, she picked up the wrist restraints and ankle restraints. These were like gloves, without individual fingers or toes, and had long straps extending from the fingertips. Zi Xi placed my hands into the restraints on my left and right wrists. Finding no issues, she tightened the straps to the maximum. After my hands and feet were all secured, she locked them with small padlocks. "Lin Yi, be good. Come, turn over. Yes, just like that. Bend your left leg." Zi Xi slid a long, black leather restraint down, successfully encasing my upper and lower left leg. My left leg, with my upper and lower leg folded, could not be straightened, meaning I was unable to walk. There were also thick pads at the knees. Zi Xi, after confirming the fit, pulled the restraint strap on my left leg as tight as possible, ensuring I couldn't break free, and then locked it with a small padlock. She did the same for my right leg. At this point, I knew Zi Xi intended to dress me as a bitch, and I instantly blushed with intense shame. "Lin Yi, now kneel on the bed." My legs were folded in such a way that I couldn't walk, so I had no choice but to kneel on the bed, occasionally letting out "hmmm" sounds. "Come, baby, bend your left arm." Before I could react, Zi Xi had already bent and tightly secured my left arm. Similar to the leg restraints, my upper and lower arm were now joined together, rendering me immobile. Zi Xi, after ensuring I couldn't escape, locked it with a small padlock and turned to pick up what looked like half of my left arm. I became even more certain that Zi Xi wanted to dress me as a dog. These would be my "hands and feet" for walking. The thought made my face feel as if it had been scalded. "Bend your right arm. It'll be done soon, and then you can be released!" Zi Xi looked at me, sprawled on the bed, with a wicked grin. My right arm was then securely bound as well. Both my arms were now incomplete, but the elbow pads were thicker than the knee pads. I was on the bed, on all fours. It was then that I understood. To make me more like a puppy and to maintain balance on all fours, the arm restraints had been padded. Just as I thought it was over, she then crisscrossed the long straps from the wrist restraints and secured them to the arm restraints. She did the same for my feet, ensuring they couldn't be pulled free before attaching small padlocks. As a human, I would have to support myself on my elbows and knees, coordinating my upper and lower legs to crawl like a dog. Finally, Zi Xi placed a black leather collar around my neck. Because my latex suit was a one-piece, the zipper was located above my upper back. With the collar on, it meant that without help, I would never be able to remove this bitch suit myself. Zi Xi bent down and knelt by the bed, placing the collar on me. From my perspective, Zi Xi now looked like a true mistress, putting a collar on me, her pet dog. After fastening the collar, Zi Xi attached a small padlock from behind. I then noticed two bells hanging from the bottom of the collar, and between the bells was a nameplate. A beautiful nameplate engraved with "Bitch Yi Yi" was fixed around my neck. The thought of this despair and shame made me wetter below...

Xi grinned wickedly, looking at me, "How is it, little puppy? Do you like your new outfit?" "You... *whimper*..." I was about to ask when I could be released, but Xi had already put a gag in my mouth. "Little puppies can't talk, can they? To prevent you from biting, I've sealed your mouth shut~~" "I'll put on all the restraints for you in a bit, and I promise you'll be satisfied~" Xi then took out the dog hood. The nose part in the front resembled a dog's, and the mask had two black dog ears on top. After I put it on, she tightened the leather straps at the back of my head, then looped the straps for the dog ears under my chin and tied them securely. These items didn't have much restraining effect; they were just to make me look more like a dog... "Oh, right, I almost forgot. How can a puppy be without a tail? Since it's your first time being a puppy, I've decided to give you a smaller {x.x}." Upon closer inspection, the tail's color was exactly the same as my hair. I even suspected it was made from my own hair. Then, Xi had me crawl to the edge of the bed and lie on my stomach. She walked behind me, picked up the lubricant from the box, squeezed out a large dollop of cool, sticky fluid, and smeared it on my rear... "*Whimper...* *whimper...* *whimper!*" Already wanting it, I was further stimulated and tormented. The pleasure from my {x.x} being massaged sent jolts through my brain. Helpless, I could only let out soft moans. Xi put on black latex gloves and slowly inserted her slender middle finger into my rear. This sensation flooded my entire body. Already wanting it, I was even more stimulated, my mind filled with the urge to release... Suddenly, I felt my {x.x} loosen slightly. After a few seconds, my {x.x}, which had been resisting, relaxed. Then I saw my {x.x} had swallowed the thing. Xi certainly wouldn't miss this chance to tease me. She pressed down on my back with one hand, while with the other, she gently tugged on my big tail. The surging desire pounded against my will.

"That's a good girl, I knew you'd be the best," Zi Xi said, happily pulling me into her embrace. My face pressed against the two "hills" in front of her, and the blush on my face deepened beneath the dog hood. "Let's go, downstairs, I'll introduce you to them!" With that, Zi Xi put the gag in my mouth, then fitted the dog hood over my head. The restraint strap was secured firmly around the back of my head and chin, and Zi Xi fastened a small lock onto it. She then picked up the leash, attaching it securely to my collar. I thought that was all, but Zi Xi then brought out that short chain, connecting it to my waist harness and the dog hood, forcing my head up. Zi Xi knew that only by doing this would the proud me feel shame. "All done! My good girl, Yi Yi, now I'll lead you downstairs. You'll crawl on all fours like a puppy." Zi Xi lifted me off the bed. My limbs supported me on the ground; if I wanted to move, I had to walk like a dog, crawling on my elbows and knees. Fortunately, the suit had thick padding. Zi Xi hadn't put on elbow and knee pads when we were on the bed, but now that I was crawling on the floor, she fitted me with the thickened elbow and knee pads. I crawled on the ground like a female dog, the bell on my collar jingling. Since this was my first time transforming into a dog and crawling, I moved very slowly. Zi Xi wasn't in a hurry, stopping every few steps to watch me crawl. We lived in a villa, and my bedroom was on the second floor, which I shared with Zi Xi. The first floor housed the living room, kitchen, utility room, etc. So, to get downstairs, I had to crawl down the stairs. I painstakingly moved my limbs, trying to keep up with Zi Xi's pace, inching my way onto the steps. Zi Xi patiently squatted on the steps, encouraging me to move down. It took me a full 10 minutes to crawl from the second floor to the first. I lay on the ground, panting, my chest heaving. When I was human, it only took 20 seconds to get from the second floor down. Now, as a dog, it took 10 minutes, and I was utterly exhausted. "Wonderful, my good dog, I didn't expect you to be faster than I anticipated. But Yi Yi, your stamina is too poor. You'll need to exercise every day. Look how tired you are just from crawling down the stairs." Zi Xi was very pleased that I could adapt to crawling like a dog so quickly. She then led me into the living room. "I just had them help me move some things to the basement. You wait here while I go call them over." With that, she tied my leash to the leg of the coffee table and walked towards the basement. "Why go to the basement? Isn't there a utility room?" Since I had been restrained like a dog, it was as if I had discovered a new world. I suddenly realized the entire world had expanded. The coffee table, which I couldn't even reach my knees to before, was now at my eye level. I tried to walk towards the television, but felt a tug at my neck. It turned out the dog leash had reached its limit. "This is my home, why are you tying me up? I'm not going to get lost," I grumbled inwardly, displeased.

"Alright, no more teasing. Daddy will be back soon. Yiyi, I'm going to put you in the bitch suit!" "Ah? I have to wear the bitch suit... aren't we going on a trip?" I asked Zixi, confused. "I want your daddy to see the results of your training all these days. Otherwise, he'll be unhappy. Who will take you out to play? Be good, lie down, and I'll put it on you." "Oh~" I mumbled reluctantly and then lay down on the bed. To be honest, this bitch suit is really embarrassing, but I'm so happy thinking about the upcoming trip. I thought to myself, "After a month of training, I can finally go on a trip! Let's see how long you can control me." The usual routine began. Zixi first applied lubricant all over my body, then squeezed me into the latex suit (the one with the open crotch and exposed chest from before), and zipped it up from behind, locking it. Next, she put on a corset and pulled the strings tightly. I was so constricted I could barely breathe. Zixi noticed when it was at its tightest and tied it off. Then she put on wrist and ankle cuffs, crossing the restraints tightly. My limbs were forced into a folded position. After ensuring I couldn't escape, she locked my limbs with small locks. At this point, Zixi put on a chastity device and playfully tugged on my tail. I couldn't help but whimper a few times. Zixi then brought out arm and leg binders and put them on me. This time, she directly put on elbow and knee pads. The padding inside the arm and leg binders, along with the elbow and knee pads, made crawling painless. After all this, Zixi put a fake [x.x] gag in my mouth and then a dog hood. But it wasn't over yet. Zixi then put on a collar. This collar was different from the last one; it was thicker. I could only turn my head slightly from side to side. Combined with the corset, I had to be careful even when turning around. After securing the collar,

"Baby, you really are a deep masochist. Just one finger in and you're this sensitive. No wonder you've become a little bitch~ Don't worry, Yiyi! You'll get what's coming to you soon!" After humiliating me, Zixi smeared lubricant on the anal hook and prepared to insert it into my rear. Zixi attempted to fit the anal hook onto me, but I didn't cooperate. I refused to give up struggling, shaking my ass non-stop. This was my first time encountering an anal hook, and the fear in my heart ignited my strong survival instinct. I kept shaking my ass to dodge, trying to prevent this foreign object from entering. Seeing me like this, Zixi directly took out her phone and tapped it. The collar emitted an electric shock, and a current surged through my neck. "Hmph! Ah-hngh..." The sudden electric shock made me convulse, and I collapsed onto the floor, panting heavily. It hurt so much! This was far more painful than before. It seemed Zixi was truly angry. If I received another shock of this intensity, I might pass out. I lay on the floor, looking at Zixi with fear. Zixi smiled and dangled her phone in front of me. "You get it now, little bitch? If you don't behave, this is your fate! Don't worry, a good dog won't be punished by its master~" The electric shock left me without the will to resist, and I could only slowly move my limbs to stand up again. It seemed I couldn't escape today! Seeing me obediently cooperating, Zixi patted my head and stroked my hair, saying happily, "That's more like it! That's my baby, the master's good little dog~" She then turned and picked up the anal hook, continuously using her fingers to help me relax while exploring inside with the lubricated hook. I knew I had to relax, but the anal hook was truly terrifying, especially since this was my first time encountering this toy... Zixi explored my rear again. The cold little ball slowly entered my {x.x}, and this foreign sensation made me feel incredibly uncomfortable. My {x.x} kept clenching. As the anal hook went deeper, a coldness filled my {x.x}. I tried to push it out, but it went in deeper and deeper. Finally, the anal hook was in place, and sweat was already beading on my forehead. "How is it, Yiyi? How does it feel wearing the anal hook for the first time?" Zixi admired me wearing the anal hook, then took out a chain, connecting one end to the hook and the other to the ring on the dog muzzle. As the chain tightened, my head was forced back. Zixi then hung my dog leash on a hook hanging from the ceiling. I could only let Zixi do as she pleased because with the anal hook in, any tug on this chain would hurt. I could only lie on the floor, tilting my head back as much as possible to make my {x.x} feel a little better. Zixi wasn't finished with the punishment. She called Zilin over. The two sisters, each holding a whip, approached me. "Yiyi, Zilin and I will each whip you 20 times this time, to teach you a lesson!" With that, the sisters began to whip my ass with their leather whips. "Wuwu! Wuwu!..." No matter how much I begged for mercy, only whimpers came out. Zixi and Zilin each struck my fair, tender ass with a whip. I didn't dare to move recklessly, as my {x.x} was fitted with an anal hook, and any movement would send searing pain... Finally, the forty lashes were over. Although the force wasn't great, merely a symbolic punishment, my fair, tender ass was still marked with scars, swollen and red, feeling a burning sensation. Zixi removed the dog leash from the hook and then detached the chain from the anal hook. "Hngh... Hah..." I gasped for air.

"I'm going out for a couple of days. You two are Yiyi's masters now! You need to take good care of her while I'm gone. Everything is arranged by me!" Zixi then took out a piece of paper and placed it on the coffee table. I saw the "Bottle Slave Rules" written on it: 1. Yiyi has transformed from the original bitch into a bottle girl, belonging to Zixi's private property. 2. Yiyi is currently not human, nor a bitch. She is a piece of furniture, an object. 3. When Master Zixi is away, Gao and Zhang are Yiyi's temporary masters and enjoy the same rights. 4. Yiyi may only relieve herself, {x.x}, etc., with the permission of Master Zixi or temporary masters Sister Gao and Sister Zhang. ...... This was clearly meant to humiliate me, and I was furious! I stared at Zixi, my face flushed red. Seeing my expression, Zixi smiled with satisfaction and stuck out her tongue. Then, she had Sister Zhang and Sister Gao move me into the basement and drove away. "Yiyi, although your mother said you two are my temporary masters, she only asked you to ensure your feeding. So, Sister Gao will come tomorrow night, and I will come the night after," Sister Zhang said to me with a smile. But in my eyes, this meant I would be confined to the basement for two days! Sister Zhang removed my gag, and I coughed a couple of times. I looked at Sister Zhang with a wronged expression, "Sister~ Can you please untie my restraints... I haven't washed my hair in two days, and my scalp is so itchy!" I tried to plead with Sister Zhang, hoping she would unlock the bottle and remove the restraint suit I was wearing. "No, dear~ Unless you agree to wear the bitch outfit and be my little dog for these two days!" Sister Zhang said, playfully inserting her index finger into my mouth. "Yiyi is so cute, I really want to turn you into a little dog to pet~" "...Sister, I want to be human for two days..." "So, there's no room for negotiation~ It seems you still want to be a bottle!" "I..." "Sister doesn't like disobedient little dogs. In that case, Yiyi should just stay obediently in the bottle~" Before I could finish speaking, Sister Zhang shoved an inflatable fake {x.x} gag into my mouth. As Sister Zhang pressed down, the fake {x.x} in my mouth grew larger and larger until it filled my entire mouth. That wasn't all; Sister Zhang then put an eye mask on me. I already couldn't see the sunlight in the basement, and with the eye mask, I was no different from being blind. "It's not over yet, Yiyi, Sister bought you a gift~" Although I didn't know what it was, it certainly wouldn't be anything good! Since I was wearing an eye mask, I had no idea what toy she had bought me. I could only hope it wouldn't torture me too much. When my fingertip touched my nose, I knew it might be a nose hook. However, I didn't feel a hook, but a retractable clip. With Sister Zhang's force, the clip was fixed in the middle of my nose. "Ah!" I cried out in pain, but due to the gag, only a "huff huff" sound came out. "I know you don't like piercings, so Sister specially bought you a nose clip. Do you like it, Yiyi?"

After dressing me up, Zi Xi looked satisfied, squatted down and touched my head and said, "Don't worry Yi Yi, won't let you be bored, let you have a good time in a while!" Said also did not forget to pull my tail, I stared at her viciously, too hateful this woman! ZiXi badgeringly took out her phone and tapped it a few times, the {x.x} and posterior below, including my buttocks were subjected to a strong sense of stimulation, an even more stimulating excitement than before rushed into my brain, but I'm a little curious, don't you want to gag me this time? Forget it! It was better to do more than less, and I didn't say anything. The current me was wearing a latex beast costume on the inside and a bitch suit dressed up on the outside, not to mention escaping, it was a luxury to have this restraint loosened up a bit. Zi Xi did not let me go, but directly holding my leash out of the bedroom, all the way Zi Xi looked me up and down, I was also embarrassed by Zi Xi's measuring gaze. I have to say, wearing this bitch suit made me even more like a little bitch, and because of the latex suit, I felt soft and basically nothing as I crawled around on all fours. After coming down on the second floor, ZiXi led me to the basement, ZiXi and I came down the steps of the basement and saw ZiLin sitting on a crate sizing me up. When she saw Zi Xi holding me she came up and squatted down to caress my body ...... "Yi Yi sister is more like a little bitch yo~" Zi Lin humiliated me but also did not forget to spank me, due to the leash I was also able to dodge, I can only helplessly begged for mercy, "Don't ...... Don't bully me anymore~" Seeing this, Zi Xi spoke up and said, "Alright, stop bullying your Yi Yi sister and fit me with that new set of restraint frames." After hearing this Zi Lin opened the box she was just sitting in, inside the box was a set of rings, steel pipes, straps, and some other listed supplies, Zi Xi didn't say anything but instead held me and made me sit on my knees on the floor. I saw Zi Lin take out the longest black cylinder in there and place it on the floor, and then install a black plate in front and one in the back and secure it, these two plates were as thick as two or three books, but each had a hole in it. Zi Lin said to Zi Xi, "Sister, bring Yi Yi up!" ZiXi saw ZiLin installing it and then led me to these two boards, and she removed my chastity belt, leaving only [X_X]. It turned out that the holes in the boards were filled with sponge, probably knee and elbow pads designed with the user in mind to be immobilized for a long period of time, but that wasn't all, Zi Lin was installing the restraints again, securing my head to the openings of the restraints, and the straps of the restraints were used to hold my limbs in place, so that I, who was already wearing a bitch suit, would be immobilized and placed in these restraints. Unlucky me, I was immobilized by ZiXi and ZiLin, then ZiXi took out an opener and fixed my mouth, so I could only let out "Oooh...". I could only let out "Oooh... The two sisters weren't finished, ZiXi and ZiLin placed the two cannons in front of me and behind me respectively, I was terrified by this scene because I had never been so fixed and conditioned, I wanted to beg for mercy, but unfortunately I could only let out a "whimpering" sound. Zixi adjusted the fake {x.x} on the front of the cannon to my mouth, and I was disgusted to see the fake "x.x" in front of me going into my mouth.

"Little bitch, you will call me Master!" My eyes were covered, and a sense of unknown excitement surged through me. "Lie on the bed, face me!" Zixi's tone was filled with the seriousness and excitement of a master's command. I lay on the bed, limbs spread open. Zixi knelt on top of me, kissing my face. I stuck out my tongue and kissed Zixi passionately, our tongues entwined. Zixi continuously invaded my mouth. "Mmm..." I couldn't breathe from Zixi's kiss. Zixi looked at me with satisfaction, then picked me up and had me stand on the bed on all fours. Zixi put on a fake {x.x}, smeared on lubricant, then put a gag in my mouth and [X]ed my {x.x}. She held my waist with one hand and pulled the dog leash taut with the other. "Mmm... mmm mmm wuwuwu!" "Baby~ A little bitch is meant to be fucked, isn't she? If you don't want to be human, then be my little bitch~" Zixi was even rougher today. I knew this was her true nature, and she had been very gentle when training me. If she had treated me like this the first time, I would have been terrified long ago. Training needs to be gradual. Zixi spanked my ass again, "Little bitch, keep barking, don't stop!" "Mmm... wuwu......." Hearing my moans, Zixi's thrusts became more intense. Finally, I couldn't hold on any longer and wet the bedsheets... "Kneel on the bed and wait for me!" Zixi commanded and then walked out of the bedroom. I, who had just climaxed, struggled to get up and knelt on the bed, waiting for Zixi to return. When she returned, Zixi was holding a new collar. This collar was black and red, looking more stimulating. Most importantly, the collar had a bell, and beneath the bell hung a name tag – Zixi's exclusive bitch. Seeing this, I blushed and dared not meet Zixi's gaze. My gag and the previous collar had been removed. Zixi put the new collar on me, not forgetting to jingle it. The tag beneath the collar was particularly glaring, and the bell made a crisp sound. Zixi fastened the dog leash and then tugged it. My body leaned forward. "Bark for Master~" "Wuwu...... Woof woof woof~" Zixi liked to make me bark like a dog. She kept pulling on my leash, and this act of sadism brought her [X]. "Keep barking, don't stop!" "Woof!" "Woof woof......." Hearing my barks, Zixi became excited again. She pushed me down and sat on my face. "Lick me!" Zixi commanded. Although it wasn't the first time, being sat on my face made me extremely ashamed. I tried my best to serve Zixi, and Zixi let out moans.
