Stepping into the familiar campus, the girl felt a strange sensation, because it was the first time she had seen the campus so empty.
She only saw the janitor acting as a doorman at the school gate, then not a single person.
This day was Sunday, of course also a school holiday.
Even on holidays, the campus would be open, available for some classes to use for holiday tutoring. Some clubs would also hold activities on holidays, so the girl wearing her neat uniform could easily enter the campus.
After parking her sex toy bicycle, enduring the strong urge to defecate produced by the large amount of drugs injected into her on the bicycle, the girl first went to the multi-purpose classroom as if going to school normally.
There, the props the girl needed to use were already placed.
Last week, the girl actively seduced two XX (definitely not large dogs) to conduct XX (definitely not bestiality) in front of everyone during an online livestream. Though ashamed, the girl did not regret it, because after that day, she could not only become the masters' sex slave again, but she also discovered that her relationship with the masters seemed to have undergone a subtle change.
The girl couldn't clearly describe the specific feeling. She just felt that she had become even closer with the masters.
Of course, besides this vague feeling, the girl's after-school study group also underwent more concrete changes.
For example, four days ago on Wednesday, the girl was forced to conduct another public training online livestream, and the girl discovered that her masters seemed to plan to hold this kind of public training every Wednesday from now on.
This time, multiple livestream cameras were fixed below the girl's neck as she was restrained, so the girl did not need to wear a blindfold and could clearly see the lewd scenes being livestreamed on the computer screen, as well as the audience's real-time responses.
And besides being restrained and unable to move, the girl's three holes between her legs including her urethra were all held open by metal tools similar to large springs. This time it was training targeting the girl's three sensitive cavities.
The masters' preparations were also very thorough. Besides the vibrating eggs, electric toothbrushes, electric shock rods, chili sauce, toothpaste and ice cubes that the girl was already very familiar with, there were also brushes, candles, wasabi, etc...
But the real-time responses coming from the screen made the girl despair.
Only able to hear the girl's crying and begging voice, but unable to see the girl's already broken expression, the audience's responses completely disregarded the girl's capacity to endure, constantly proposing various terrible ideas.
After losing bladder control, her bladder was immediately filled again by a mini enema device, then made to lose control again amid electric shocks to her bladder neck...
The G-spot on the front wall of her vagina was pressed by an electric toothbrush coated with wasabi, while the same position on the other side of the flesh wall in her urethra was sandwiched by another electric toothbrush coated with mint toothpaste. At the same time, the inside of her little nub in her urethra was invaded by an electric toothbrush coated with chili sauce, while her little nub was surrounded by ice cubes...
Four brushes respectively coated with chili sauce, wasabi, mint toothpaste and crushed ice were smeared all over inside her rectum, while her vagina simultaneously put on a show of stuffing vibrating eggs into her uterus...
In the eyes of the girl who had lost consciousness many times and been forcibly awakened by stimulation inside her body, the terrible suggestions proposed by the audience could almost scare her unconscious directly.
As a result, the masters actually executed according to the suggestions, lifting up the girl's lower body to let hot wax drip directly into the depths of her three holes!
Though the masters had prepared low temperature candles and the girl was not injured, under the terrible stimulation of being burned simultaneously at her bladder neck, cervix and rectum end, the girl still completely lost consciousness again...
Then of course the girl was viciously r@ped awake by the masters again. After the online livestream public training ended, the girl still had to serve as the masters' sex slave, urinal, and little tutor for the study group, guiding the male classmates' studies while enduring the masters' cruel r@pe amid weak wails.
However, as if to compensate, the masters set every Tuesday as a rest day for the study group, allowing the girl to get sufficient rest on the day before the public training to prepare.
Even though on Tuesdays, when the girl found those two female classmates and clarified that she was no longer quitting being lewd, what should have been just ordinary comfort gradually transformed into various teasing under her unique bewitching aura, making her orgasm repeatedly as she was played with by the two female classmates again.
But compared to the study group masters, the "teasing" of the two female classmates was much gentler, just right to let the girl relieve her carnal desires without consuming too much energy.
Or rather, gradually becoming intoxicated by the fun of playing with the girl...
Additionally, the two XX (definitely not large dogs) also became regular guests of the study group.
After days of XX (definitely not bestiality), the two XX (definitely not large dogs) had already memorized the girl's scent. Three days ago on Thursday, before the leader even applied female dog secretions on the girl, the two XX (definitely not large dogs) had already actively mounted the girl.
The girl who had never known about the female dog secretions also actively spread open her anus to welcome them, successfully completing her first XX (definitely not bestiality) without any external assistance.
Then, while receiving head pats as a reward from the leader, the leader proposed the activity for this day.
The activity for this day was an exam the masters gave the girl, an exam as a sex slave.
According to the leader, since the girl could get good grades in her "studies" which were just a side job, and had also gained the recognition of the two XXXXX (definitely not dog masters) as a "female animal", then in terms of being a "sex slave" which was most important, she should also undergo an assessment to verify if she was qualified.
The exam venue was this school that the girl attended.
However, exams and such were of course just an excuse. Even the girl understood clearly that this was just another game.
But even though she understood in her heart, the excuse of an "exam" still made the girl secretly decide in her heart that she would work hard.
In the multi-purpose classroom, besides the cameras that had already been set up, there was also a note leaving the masters' instructions.
As a "sex slave", of course she had to absolutely obey the masters' orders, so the girl's exam content today was to execute the instructions left by the masters on campus.
The first instruction was for the girl to strip naked, then put on the nipple chains and clitoral ring with bells prepared by the masters, and leave the multi-purpose classroom.
Seeing this first order, the clever girl already knew that today's "exam" would probably not be simple...
Leaving her neatly folded uniform in the multi-purpose classroom, completely naked except for the lewd ornaments on her nipples and little nub, the girl left the multi-purpose classroom.
Stepping barefoot out of the classroom, the girl's naked body with only lewd ornaments was suddenly exposed in the school corridor.
Even though there was no one in the corridor now, the girl was so embarrassed that she immediately covered her chest and groin with her hands.
In the girl's impression, this school corridor was always crowded with students. Though there was no one now, it still gave the girl the illusion of exposing her shameful appearance in front of many classmates...
When the girl saw that "small box" next to the classroom door, she felt a chill run from her feet straight to her head. The "small box" in the masters' instructions was actually a metal piggy bank!
Though this piggy bank had an outlet, it was locked with a small lock. And there was another note on the piggy bank, telling the girl that she would naturally be able to get the key back after she completed the "exam".
A metal piggy bank that couldn't be broken or opened, plus the note, immediately made the girl understand that the "exam" prepared by the masters was actually to have her run naked on campus!
But the masters' orders could not be disobeyed. Even though her hand holding the key was trembling in fear, the girl ultimately still threw the key into the piggy bank...
Hearing the sound of the key falling into the piggy bank, the girl understood she could no longer enter the multi-purpose classroom to get her uniform back. Besides completing the "exam", she had no way out.
So, the girl followed another instruction on the piggy bank note, steeling herself to take the first step of her campus naked run journey...
As soon as she took the first step, the cold floor and the bell sound between her legs reminded the girl of her shameful situation.
Not only was she naked, but her erect nipples and little nub also had perverted lewd ornaments hanging on them. Inside her slightly swollen lower abdomen, there was also a large amount of drugs filling her rectum, urging out a strong urge to defecate.
On the other hand, the coldness of the floor also made the girl notice the surrounding temperature.
Though it wasn't very cold today, winter had already begun. Even with the windows tightly closed, the corridor that could barely be considered indoors was still a bit cool.
However, the girl's body didn't feel cold, but rather hot and flushed. That was because the girl's body had already become aroused.
The naked run journey had not yet begun, but the girl had already become aroused due to embarrassment.
Even though no one could see, the girl's body still turned a bright red all over.
Moreover, in fact it wasn't that no one could see, because even before entering the multi-purpose classroom, the girl had already seen notices posted on the walls indicating that due to the photography club's activities on this day, cameras had been set up in various places around the school.
Now there was a camera set up right behind the girl, clearly filming the girl's exposed behavior of emerging naked from inside the multi-purpose classroom.
The note in the multi-purpose classroom let the girl understand that the notice was fake. Those cameras were actually set up by the masters to monitor her "sex slave exam" process, for the masters to enjoy, grade and keep as a record.
In other words, her campus naked run would be seen completely by the masters, and might even be uploaded to websites for public sale after the masters blurred her face, just like when she accidentally made a mistake two days ago!
Recalling how videos of herself dressed up as a little female dog lifting her hind leg to urinate towards a street lamp, and then seducing homeless people for group sex, were already circulating all over the internet, the girl suddenly shuddered and actually reached a small orgasm just like that!
A small amount of sexual fluids splashed on the ground. The girl whose legs suddenly went weak immediately came back to her senses.
Though her body craved even more after orgasm, the girl also came back to her senses from the shame.
The girl was still that shy girl. The exciting campus naked run would only make the girl's body orgasm from shame, but the girl who tried hard to strictly maintain morals still hoped to quickly complete the "sex slave exam" and end this shameless naked run journey.
Moreover, the girl hadn't forgotten this was the school campus. Even though it was a holiday, since the girl could come back, other students naturally could too.
In fact, when entering the school gate earlier, the janitor acting as doorman had already said that before the girl came back, a large group of students had already come back, seemingly to conduct holiday tutoring.
Besides the girl, there were other students on campus...
The girl didn't know who those students were. She had no idea which classroom they were in, or when their tutoring class would end, or even if it was one class of students or many classes.
Moreover, this was the masters' order, her "sex slave exam". The girl would not only not allow herself to have even the slightest disobedience, but would urge herself to work hard to execute the orders, striving to get good grades in this "sex slave exam".
Desperately urging herself in her heart, amid huge unease, the girl took another step, beginning her campus naked run.
The campus corridor floor was smooth and even, not uncomfortable to walk on barefoot, but the girl didn't dare walk too fast, because the clitoral ring hanging on her little nub had a small bell attached.
Though the bell wasn't big, its sound wasn't small, very obvious in the empty campus.
The girl didn't know which floor the students who came back for tutoring were on. If the students stayed in the classrooms it would be fine, but if any students in the corridor heard the bell sound and followed it, the girl would be finished.
As for the "cheating" method of grabbing the bell to stop it from ringing, that had already been sealed off at the subconscious level. In the girl's thinking, this option did not exist.
On the other hand, the girl also had to desperately endure the churning urge to defecate in her rectum, making it impossible to speed up...
The cold sensation penetrating her soles constantly reminded the girl that she was completely naked.
The huge crisis made the girl take each step with trepidation. The nervous mood not only raised her adrenaline and further enhanced her senses, but also made the secretions between the girl's legs increase again.
The girl who was carefully paying attention to her surroundings didn't notice her own situation.
Her cherry red skin, furrowed brows, hazy gaze, and even the soft panting coming from her mouth all revealed a bewitching allure.
The naked run journey had just begun, but the girl had already entered an aroused state of shameful exposure.
However, the girl's mind was still clear. She knew clearly what her destination was. The instructions on the piggy bank note ordered the girl to go to the abandoned toilet on the top floor of the school building.
Stepping onto the stairs, her unease intensified again.
Unlike the unobstructed corridor where unknown classmates could appear at any time and spot the girl's naked figure from afar, the sound conduction in the stairwell was very good.
The stairs with only the girl now were even quieter than usual.
Fortunately, the students in unknown locations seemed to still be in tutoring class. Going straight up to the top floor in the stairwell, not only was the girl not discovered by anyone, she also didn't hear any unusual sounds.
The girl who safely reached the abandoned toilet on the top floor found a set of "exam tools" left by the masters in the stall.
The camera placed very obviously in the abandoned toilet did not have any "hidden filming" issues. The naked girl had to conduct her first exam in front of this camera.
The "exam tool" was an enema syringe even thicker and longer than the girl's thigh. The girl's first exam was an enema exam.
There were no requirements in the masters' note. The girl who had already emptied out the drugs in her belly could only try her best to do the "enema" well. Placing the full large enema syringe upright on the ground, inserting her anus onto the nozzle, then using both hands to gradually press down on the enema syringe, the girl successfully let the large tube of clear water inject into her belly.
Then the girl began to suck in a second tube. Without the masters' orders, the girl dared not arbitrarily reduce the enema amount even more.
Moreover, because she had just been given a glycerin enema, the urge to defecate caused by an equal amount of clear water was of course far less than the drugs.
So when the girl forcibly injected clear water to create an equal urge to defecate, her belly had already been filled to bulging and really couldn't take in any more.
Then the girl walked into the stall on trembling legs, viciously spraying out the filth in her intestines under the camera!
Then she conducted a second round of injection...
Until what came out of her belly was completely clear water, the girl still injected two more rounds before daring to end this first exam.
And the reason this was called the first exam was because the note in the abandoned toilet instructed the girl to go to another place on campus. The exam was far from over.
Stepping out of the abandoned toilet, the girl was even more ashamed than when she entered.
Wearing dog ear accessories on her head, cute dog paw pads on her hands and feet, the girl crawled on all fours like a little female dog, leaving the abandoned toilet.
Moreover, the girl leaving the toilet still had a bulging belly, obviously having conducted a large amount of enema, and the girl's anus had a dog tail anal plug in it.
The inflatable anal plug was very secure, allowing the girl who had given herself an extreme enema not to worry about being unable to hold it in.
However, this inflatable anal plug also had a key attached. Before the girl reached the next location and obtained the key, she had no way to remove it.
This section of the female dog journey was the girl's second exam.
The destination was the cafeteria bathroom, meaning the girl still had to go down stairs.
Already familiar with dog-like movement, even crawling down the stairs head first posed no problem, but for balance, the girl's high raised buttocks had to constantly sway.
Already deeply aware from videos how lewd her stair-descending posture was, the girl in the school campus couldn't help but blush bright red.
If her current lewd posture was seen, the girl would definitely be ruined. Intense shame washed over her, and the girl even had visions of unfamiliar classmates appear before her eyes.
Amid a barrage of reproach, combined with the plugged-up sensation from the extreme enema and the stretching stimulation in her rectum, the girl reached another huge orgasm on the stairs!
Under the strong orgasmic convulsions, the imaginary classmates berated the girl's perverted behavior even more.
Too ashamed to show her face, the girl could only struggle to lift her front and hind legs still trembling in orgasm, and quickly crawl down the stairs to escape the classmates' scolding.
Amid the classmates' stares and a chorus of insults, the girl who kept orgasming finally managed to hide in the cafeteria bathroom.
The girl who pushed open the bathroom door and rushed in saw a male student looking at her!
The illusion instantly vanished. Faced with a real unfamiliar male classmate, the girl couldn't help but let out a scream. Her ongoing shameful orgasm suddenly intensified!
The suddenly erupting physical stimulation, mixed with the already intense shameful pleasure, made the girl's eyes roll back as she was forced to directly reach a double orgasm in front of the unfamiliar male classmate!
The girl who collapsed on her side gasping for breath then discovered the male student's face was calm and his body flat.
It turned out to be just a life-size poster.
The girl who had never entered the male cafeteria bathroom before finally calmed down from the intense orgasm after seeing clearly this poster reminding students to wash their hands after using the bathroom.
Curiously examining this cafeteria bathroom that should normally be crowded with students, the girl found another set of "exam tools" in the innermost stall.
Following the instructions on the note, she crawled to the urinal and raised her thigh.
The girl who had completed bestiality could now transform into a perfect little female dog in front of her masters. Under strict training, the current girl would instinctively hold her urine even when unconscious.
Without electric shocks, it was much more difficult to r@pe the girl to incontinence than before. So during her shameful orgasm just now, she only squirted out a large amount of sexual fluids, while the urine was still tightly held in her bladder.
Assuming a lewd posture, the girl pressed play on the tape recorder prepared by the masters, then quietly waited.
The strong urge to defecate in her belly produced an urgent need to urinate, but the tape recorder was silent. The girl could only wait for instructions from this inanimate object.
Once again deeply realizing she was not even as good as an inanimate object, the girl became even more determined in her heart to get good grades in this "sex slave exam" and work hard to become a qualified sex slave!
Finally, the master's voice played from the tape recorder. Hearing the simple words "release urine", before the girl's consciousness could react, her urethral sphincter had already relaxed on its own, and urine immediately gushed out.
But before the girl could relax, the tape recorder played the words "hold urine". The body's reaction that had already been trained into instinct stopped urinating on its own before the girl was even aware of the instruction.
Just with the master's authorization, even a small tape recorder could control her right to excrete, making the girl once again realize her own lowliness.
When stopping urination for the second time, the girl's waist stiffened, and she orgasmed again in infinite humiliation!
While orgasming, she intermittently expelled the clear water from her intestines.
Even after expelling all the large amount of clear water inside her body, the girl's legs were still trembling uncontrollably. The multiple excretory orgasms gradually depleted the girl's physical strength.
But the exam was not over yet, the girl had to persevere.
Coming out of the cafeteria bathroom, the girl's appearance changed again.
Removing her female dog disguise, the girl walked out of the bathroom upright with her hands behind her back.
The girl walked unsteadily, wearing a pair of ultra high heels that only allowed her toes to touch the ground.
Her hands cuffed behind her back, her thumbs restrained by small thumb cuffs that were connected to the base of a huge rod. That ferocious huge rod made of fist-sized balls covered in soft spikes was now stuffed in the girl's rectum, vibrating, rotating and twisting madly!
Besides the thumb cuffs, the base of this huge rod also had a small hook.
Following the note's instructions, after inserting the rod, the girl hooked the small chain with the bell on her clitoral ring to the base of the rod.
The finger-length small chain instantly made it impossible to pull out the shockingly long huge rod. Putting on the thumb cuffs further made the girl lose the ability to remove the clitoral ring and small chain.
Before getting the key to the thumb cuffs, the girl could only maintain this perverted appearance even more obscene than the female dog disguise!
The girl's hands also held a bag containing the anal plug and tape recorder she had just removed.
Then, as she struggled to move forward holding the small bag, the girl finally couldn't help but cry.
The huge rod rampaging madly in her rectum not only brought the girl waves of pleasure, but the base of the rod constantly swaying in her anus also pulled on the small chain, bringing intense stimulation to her little nub while making the small bell ring out constantly.
The girl wearing high heels could only struggle to maintain balance with great difficulty. Even walking at a normal pace was very strenuous, let alone running.
But the master's instructions ordered the girl who kept making sounds to attract attention yet couldn't escape to walk to the auditorium. And part of the path from the cafeteria to the auditorium was outdoors!
But thinking that she might be seen in this state, and by classmates who knew her identity, the girl still cried out of fear.
At the same time, the sexual fluids between her legs also accelerated their secretion again.
Nervousness, fear, grievance, despair - all transformed into mental pleasure under her masochistic consciousness, working with the anal rod to force the girl into continuous orgasms.
But her empty urethra and vagina not only sprayed out large amounts of squirting fluids during orgasm, but also sent out signals of craving to the girl.
Unfortunately her hands so close by were restrained and unable to masturbate. The small chain connecting her little nub and the anal rod pressed against her small slit, constantly teasing and urging on the instinctive desires of her urethra and vagina.
Moreover, for this day's "sex slave exam", the girl's vagina had not had anything inserted for several days.
For many days she had been continuously anally r@ped by the masters. Though she still orgasmed non-stop, it also made her empty vagina crave more and more...
Constantly advancing in desire, until the cold wind hit her body, the girl was startled to realize in shock that she had already walked to the outdoor corridor connecting to the auditorium.
Suddenly awakening from her trance, huge shame washed over her, making the girl's footsteps falter.
The girl was currently wearing a pair of ultra high heels that only allowed her toes to touch the ground. The result of her faltering step instantly made the girl lose balance!
Fortunately the girl was familiar with dance techniques. She only staggered a few steps to regain balance without falling.
But in those few staggering steps, her instinct to open her arms to help balance viciously pulled on the anal rod, also viciously pulling on the small chain connected to the base of the rod at the same time, viciously pulling on her sensitive little nub!
In those few staggering steps, the shame of appearing outdoors, the panic of losing balance, and the painful stimulation to her little nub all surged forth simultaneously, pushing the girl to the peak of orgasm once again!
From the filmed footage, it looked like the girl had eagerly jumped out into the outdoor corridor. The large amount of sexual fluids spraying from between her legs further proved that the lewd girl in the image had shamelessly reached an exhibitionist orgasm while jumping!
In the auditorium, the girl once again saw the lewd exam questions specially prepared for her.
On the stage, facing the empty auditorium with only one camera, the girl felt as if she was facing countless teachers and students.
Moreover, this time the girl was not discovered in her lewd true face, but had to actively reveal this perverted truth!
Following the instructions, the girl had to loudly announce the purpose of her return to school today on the stage, in front of the entire school's teachers and students.
Announce to everyone that she was a depraved examinee who had specially returned to school to take the "sex slave exam" in order to become a lowly "sex slave"!
From the start of the announcement, huge shame, humiliation and guilt had already completely filled the girl's heart, mixing into an unbearable extreme mental orgasm!
The girl herself didn't notice that at the beginning she was just following orders, forcing herself to read out the lewd sentences specified by the master in a slightly louder volume.
But in her daze, the girl read louder and louder, her voice echoing in the empty auditorium.
Until she read out her own name in front of the entire school's teachers and students, declaring that in order to become a "sex slave", she hoped to abandon her human identity and was willing to become a urinal slave for the entire school, letting everyone freely release their desires on her body - the girl was almost shouting at this point!
At the same time, the girl's mental orgasm also broke through its peak!
Not only did her groin squirt again, but as her whole body convulsed, the girl fell to her knees rigidly on the stage, then collapsed forward as if actively kneeling and bowing to the entire school's teachers and students, adding a perfect ending to this oath ceremony.
But the girl had actually really fallen down, so when her forehead slammed onto the stage floor, the girl was still awakened by the pain amid a bout of dizziness.
She also simultaneously understood what an extremely lewd act she had just done.
The girl's waist stiffened, and another small amount of sexual fluids sprayed from between her legs...
Then, the girl had to change her attire again and set off towards the next destination.
The thumb cuffs were removed, but after stuffing another huge rod into her long-waiting urethra, her hands were locked in handcuffs again.
Moreover, the girl's next actions would be completely outdoors!
In the teaching building, although the corridors facing outside also had transparent windows, the girl knew that under the morning sunlight, the difference in lighting between indoors and outdoors would make it difficult to see inside from outside.
Outdoors, only close-up horizontal observation could see clearly inside, and the girl was always moving on upper floors, so outsiders naturally had difficulty seeing the girl's naked figure.
But this time, the girl was instructed to go to the emergency exit of the gymnasium, which was where the girl was first molested by male classmates.
Today there were no club applications, so the gymnasium wasn't open at all. The girl could only go around the outside of the gymnasium.
That meant the entire journey would be outdoors!
Under the sunlight, her pale flesh was extremely eye-catching.
Although the gymnasium wasn't close to the school gates, there were several outdoor sports fields outside the gymnasium. That open area had no cover at all, and could be clearly seen even from far away.
Even some classroom windows in the teaching building faced towards the gymnasium.
Moreover, the girl hadn't forgotten that there were still other students on campus now.
If her current appearance was discovered, she who had orgasmed many times and had both excretory holes cruelly ravaged by huge rods would have no way to escape. She could only be caught on the spot in despair, with all her lewd fetishes completely exposed!
On the other hand, the endless instructions and exam with no end in sight also made the girl very uneasy...
The girl who was only focused on maintaining balance and hurrying forward didn't notice that she was leaving an obvious trail of water on the path she walked...
Behind the gymnasium, the girl's hands were finally freed. Her hungry vagina that hadn't been penetrated for days could finally be inserted with a sex toy.
Three huge rods battled each other inside her body separated by two thin sensitive flesh walls, bringing the girl infinite pleasure. Combined with the repeated torment, the girl's consciousness had completely sunk into carnal desire.
Fortunately the girl still remembered the exam. The master's orders were of course much more important than her own desires.
Stuffing the fourth rod connected to a strap into her mouth, fastening the strap behind her head, the girl who could only raise her head allowed the forced orgasms brought by the three rods to her body to continuously erupt as she trembled back to the teaching building.
Then the girl finally understood why the master no longer restrained her hands.
This time the girl had to return to her own classroom floor, so she had to climb the stairs again.
However, at this point the girl could no longer even maintain her facial expression, and could only allow her lewd orgasm face to be completely exposed. Her legs were even harder to control.
Without her hands to support herself, the girl would have no way to climb the stairs.
Grateful in her heart for the master's thoughtfulness, further strengthening her determination to get good grades and work hard to become a qualified sex slave, the girl climbed the stairs amid endless orgasms.
Finding the final note at the designated location, the girl learned from it that her exam would be complete after finishing one last journey.
The journey to the final stop was extremely simple. The girl only needed to blindfold herself, feel her way back to her own classroom, crawl to the front of the teacher's desk, assume the specified lewd posture, and recite the "slave oath" she had long memorized by heart. Then the "sex slave exam" would be considered successfully completed.
Even though the repeated orgasms had left the girl nearly exhausted, and her sensitive body that kept intensifying in orgasm made the orgasms erupt more and more violently, for the sake of her masters, the girl still kept encouraging herself in her heart.
Supporting herself against the wall as she moved forward, silently counting the number of classrooms she passed, she finally reached her own classroom.
Gently turning the doorknob, it was indeed unlocked. With joy in her heart, the girl finally returned to this classroom where she normally attended class.
Recalling her current attire, strong shame welled up in her heart again, but it couldn't overcome the joy of about to complete the "sex slave exam".
The strange expression of a sweet smile amid orgasm created an unusual innocent allure.
Because her eyes were blindfolded, the girl felt even more like she could really see all her usual classmates seated, and even seemed to faintly hear the sound of soft breathing.
In enormous shame, she sat on the teacher's desk and spread her legs wide, reaching her hands under her thighs to gently spread open her small slit that was tightly gripping two huge rods.
The shame even more intense than before made the girl directly reach orgasm again!
The simple action of spreading open her small slit was of course something the girl had done many times, but this time was different.
This "sex slave exam" was not held for no reason.
Just like when the girl first swore to become a sex slave, besides the slave collar, the master had also given the girl nipple rings as a gift.
This time becoming the master's sex slave again, the master similarly wanted to leave an indelible mark on the girl's body.
Moreover, the piercings for the nipple rings and clitoral ring still had a chance to heal, but the mark the master gave the girl this time was one that could not be erased.
The master wanted to give the girl a tattoo!
And just like how the piercings were on her nipples and little nub, the place for the girl's tattoo was also a sexual organ - the two delicate lips forming the girl's tightly closed small slit!
Recalling that day, spreading open her small slit in front of the tattoo artist, the girl who was both shy and scared trembled as she waited for the tattoo.
Although being pierced needle by needle on her sensitive zone, the terrible pain was indeed hard to bear, but this was the slave mark given to her by the master. The pain stabbing into her small slit felt like carving the master's mark into her heart. The girl could not and had no intention to resist.
Moreover, the girl's body had long been trained into a severe masochist. In fact, besides the pain at the beginning, the girl gradually became aroused from the stabbing pain, then reached uncontrollable orgasm.
Later it took the masters working together to hold down the orgasmically convulsing girl motionless for the tattoo to be successfully completed...
Then during the recovery period, the girl's small slit was sealed. For several days, the masters only focused on playing with the girl's anus.
The girl herself hadn't seen it, but she knew that the mark tattooed on the inside of her small slit was two lines of small text.
On one side was carved "sex slave", on the other side was carved "urinal". Though simple, it clearly and definitively displayed the girl's identity.
Even clearer than all the perverted sex toys and obscene piercings on her body, as long as one wasn't illiterate, they could immediately understand from these two lines of text just how lewd the girl was!
The girl felt extremely ashamed.
At the same time, she also felt waves of sweetness. That was the mark left by her masters...
In this strange atmosphere, the girl removed the restraints on her mouth and once again swore to be the masters' faithful sex slave, until forever...
Then, applause erupted in the classroom!
The blindfold was also removed at the same time. The girl was shocked to see that her familiar classmates were really sitting in the classroom before her. Not only were there members of the study group, but even other classmates were present!
There were no female students, but all the male students were gathered!
Additionally, there was also the homeroom teacher, new teacher and art teacher. Even the leader and others were there! The leader and others in casual dress had been brought in by the homeroom teacher, and they were wearing visitor badges.
To the masters, this tattoo on the girl's body was much more important than nipple rings.
Nipple rings could at most only prove the girl was a lewd woman, but the tattoo formally carved with "sex slave" and "urinal" was a means to make the girl unable to ever escape this identity.
The leader and others were just small-time thugs, not vicious g@ngsters. They had never intended to completely ruin the girl's future.
They hadn't given the girl a tattoo before because they had planned to let her start a new life after they got bored of playing with her.
But the threats from the girl's uncle made the leader and others finally clearly realize that they didn't want to give up ownership of the girl, not ever.
That day the girl had been willing to expose her true face in exchange for the muscular man quitting smoking, and the girl had succeeded. Then, the muscular man really never smoked again.
Giving the girl an inescapable carved mark, besides making it so the girl could not leave them, also represented that they no longer planned to abandon the girl. Not now, and not in the future either.
As for the homeroom teacher and others, they had never treated the girl as a pure plaything from beginning to end.
Though they were very excessive when playing with the girl, that was only because the girl didn't mind. In daily life, the girl was still their obedient student and friendly classmate.
Of course, everyone gathered here wasn't just to watch the livestream of the girl's "sex slave exam" and tattoo in the classroom.
The homeroom teacher had investigated early on that only they had tutoring classes today, which is why they let the girl run around naked on campus recklessly without fear of being discovered.
For the same reason, they could do anything to the girl now.
The masters whose large penises were painfully hard were already impatient. The long-haired man had even taken out various sex toys and restraints from the large bag he brought. The red-haired man had been filming with his camera non-stop since the girl entered the classroom.
Even those newly joined male classmates had been bewitched by the girl's series of perverted performances just now, their penises painfully hard.
Besides having the girl reveal her tattoo, today they also wanted all the remaining male students to join the study group.
After all, a class was a whole. It would be easy for interconnected classmates to notice if something was being hidden. The secret of the study group would only be safest if kept by the entire class together.
Of course, limited to male students only.
What awaited the girl would be another long session of cruel r@pe with increased members!
The girl hadn't thought so much. She only knew from the screen still playing nearby that all her perverted behavior just now had been seen completely by these non-study group classmates.
Though shy, the clever girl also understood that this way, these classmates who had witnessed her slave tattoo would also become members of the study group, becoming her masters.
The leader's younger brother who had been sitting in his own seat was the first to break the silence: "You did well on the exam."
The leader's younger brother would be the first person to enjoy the girl today. This wasn't decided by rock-paper-scissors, but purely because as the president of the study group and a fellow student, he was best able to incite those "good students" who hadn't yet laid hands on the girl but were already itching to do so.
Walking from his seat to in front of the girl, the leader's younger brother extended his hand to the girl.
The docile girl offered no resistance at all.
The leader's younger brother was very satisfied. In fact, he was very satisfied with the girl's actions today. Simple notes had accomplished controlling the girl's actions, which made him very satisfied.
Looking at the girl's cute face with a smile yet blushing, thinking how the girl hadn't serviced anyone today, the leader's younger brother suddenly felt an unprecedented impulse.
"Little slut."
Using his finger to lift the girl's chin, the leader's younger brother brought his face close: "Full marks."
Before she could thank him, the girl's joyful expression suddenly turned to shock.
The leader's younger brother kissed the girl on the lips.
Feeling the tongue invading her mouth, the girl who had been trained into an oral sex expert could only close her hazy eyes and clumsily respond.
Clumsily responding to this first kiss...
