Time quickly passed into late autumn, and it had been nearly a year since I met the master. One morning, the master came to the basement, removed all my restraints, led me to the bathroom for a bath, shaved my lower body, then put a gag in my mouth and took me to the living room of the master's villa.
Standing naked, I saw a rectangular coffee table placed in the center of the hall. The master pulled me to the table, had me climb onto it lengthwise, and tied my limbs to its four legs. A pillow was placed under my lower abdomen, my legs were spread wide apart, and my buttocks were raised high, fully exposing my genitals and anus to the master. Then, the master brought a syringe filled with a liquid and injected it into both halves of my buttocks. The master said, 'Yue Nu, this is an anesthetic. I'm about to brand you as my private slave. Once the anesthetic takes effect, it won't hurt much. Do you like the idea of being branded? Soon, the brand will be on the creases of your buttocks beside your anus. You won't see it when you stand, but when you crawl like a dog or raise your buttocks, the words "dog slave" will be revealed.' After speaking, the master left and returned with a red-hot branding iron, pressing it firmly against one side of my buttocks. Immediately, the room was filled with the strong smell of burning flesh. Then, another branding iron was pressed against the other side. Although it wasn't very painful, I was drenched in sweat. The master applied something to the brands that felt cool and refreshing. Next, the master took out four silver rings, slightly larger than a ring, from an aluminum box and pierced my labia majora, placing two rings on each side. These rings were made of high-hardness stainless steel, and the master sealed them shut so they couldn't be opened by hand. After completing this, the master untied me, removed my gag, and I knelt beside him with my hands behind my back, feeling a sense of pleasure and satisfaction. A mixture of sexual fluids and blood dripped from my genitals onto the marble floor, forming a pool. The master ordered me to lick the floor clean, and I obediently licked up all the spilled fluids.
Afterwards, my buttocks and labia ached for two to three weeks. Once my lower body had recovered, the mark of being a dog slave was deeply branded not just on the curve of my buttocks but also forever in my heart. Every time I raise my buttocks, I am reminded that I am a dog slave, my master's lowly bitch, craving his punishment and loving caresses to satisfy my desires. At this thought, my lustful fluids uncontrollably flood my lower body. As the weather began to cool, my master gave me a thin blanket to cover myself, but I had grown accustomed to sleeping without anything, so every day I would hold the blanket in my arms, tightly clasped between my legs, as if to fill the void in my lower body for comfort.
Today, my master led me out of the basement to the bathroom for an enema and a bath. Afterward, we went to the bedroom and began a storm of passion. Every time I make love with my master, it feels like a long drought meeting sweet rain, overwhelming with joy. Yet, this time, it was as if I was floating among the clouds or sinking into the depths of a thousand waves. My hands were tied under the collar, the chain lifting my head high as I knelt on the bed, raising my buttocks high. At that moment, I imagined the words 'dog slave' on either side of my anus in the curve of my buttocks were clearly visible. My master's excited, iron-hard YJ thrust into my anus from behind, and I moaned with pleasure. My master commanded that with every thrust, I must say 'I am a dog slave.' Thus, as my master alternated between my two holes, I continuously repeated 'I am a dog slave.' In the throes of climax, I wantonly screamed and repeated 'I am a dog slave.' This time, my master only gave without release, leaving me in a state where I could neither live nor die. My entire body felt as if electrified and numb, my limbs convulsing, thick white juice flowing from my vagina, until finally, I lost control of my bladder and collapsed weakly on the bed, and only then did my master stop.
After cleaning me up, the master returned to the living room and sat on the sofa. I knelt in front of him, and the master said, 'Yue Nu, although you have been fully developed into a mature bitch, you still do not satisfy me completely. The next step is to intensify the training of your senses and the development of your sexual organs to enhance the sensitivity of your body and your inherent lewdness.' The master then got up and brought over a box and what appeared to be a tail. It was an electrotherapy device with an adjustable voltage regulator. This tail was to be installed on me; the plug was unusually thick, about the size of my wrist, 10 centimeters long, oval with a base. Connected to the base was a bunch of black, elastic strands, very soft, each about as thick as a knitting needle, with a small ball at the end. When still, it looked like a bunch of upright flower stems, but with the slightest shake, the small balls at the top would scatter, droop, and sway back and forth. From beneath the base, a wire also extended, connected to a vibrator. The master ordered me to lie down, locked my hands under the collar again, had me prop my cheeks with my hands and support myself with my elbows on the ground, kneel with my buttocks facing him, and my ankles still chained to the waist belt. My buttocks were once again raised high. The master inserted the tail into my anus and then placed the vibrator inside my vagina, commanding me to crawl around the living room. As I struggled to move forward, any movement of my body caused the tail on my buttocks to swing up and down and side to side, the small balls at the end of the tail flickering back and forth, lightly hitting the sides of my buttocks and my private parts. This constant teasing touched the sensitive parts of my body, making me itch with desire, and my sexual desire was once again aroused. Suddenly, the vibrator in my vagina began to vibrate violently, and the small balls hitting my buttocks began to discharge electricity. My body started to tremble uncontrollably, every crawl bringing an intense stimulation, and my lewd fluids began to flow out again, dripping onto the ground I crawled over. It turned out that the tail contained batteries and a remote control device, no wonder it was so large. The master could attack me at any time.
The master called me to crawl to his side. I had grown accustomed to actively licking the spilled lewd fluids off the floor, then obediently raising my buttocks high towards the master as commanded, with the vibrator still pulsating inside me. I moaned in satisfaction as the master took out two silver acupuncture needles, three inches long, and deeply inserted them into the roots of my labia majora on both sides. There was no pain, only an increase in pleasure. The master then attached the electric clips from the therapy device to the needle handles on either side of my labia. As the current was gradually turned on, my labia majora began to pulsate at a frequency of once per second, opening and closing rhythmically. The master slowly increased the current, causing my labia majora to spread wider, flapping continuously and causing the four rings on them to clink together, producing a metallic sound. The master mentioned he could now see the vibrator inside my vagina. Waves of pleasure surged through my brain, my body felt as if it was exploding into fragments, and the lewd fluids mixed with thick, white discharge gushed out, splattering all over my thighs as my flapping labia flung them about, leaving a mess below. The master then removed my tail and the vibrator from my vagina, pulled out the silver needles from my labia, and inserted them into the Huantiao points on either side of my buttocks. He explained that these points could control the intense movement of the gluteus maximus and also stimulate the movement of the pelvic joint. After attaching the electric clips again, the master began to operate the device. Just after removing the tail, my anus hadn't completely closed, and now my gluteus maximus muscles began to violently pulsate, my entire thighs weak and trembling uncontrollably, spreading apart and coming together rhythmically, with the gluteus maximus muscles causing the pelvis to similarly open and close.
My anus visibly opened and closed on its own, with gusts of cool air rushing into my rectum. The master remarked that my rectal tube had bulged, appearing red and glossy, utterly magnificent. He instructed me to feel the rhythm of the movement and control the opening and closing of my anus accordingly, assisting me as I inserted the tail, causing my anus to contract, and pulled it out, making it expand, continuing this training regimen. Exhausted and drenched in sweat, I began to lose control, crying out as I collapsed weakly onto the floor.
Afterwards, the master gave me a bath, reattached the tail, inserted a vibrator into the vagina, and used two small copper locks to secure the four rings on the labia majora. The key was hung on the ring at the front of my corset belt. Still bound in this manner, I was then slowly led back to the basement, concluding today's training.
