Volume 5: Expanding the Harem - Chapter 101 

After spending Sunday in humiliation, the girl resumed her daily school life. 

Rising early to wash up, after her morning bath and breakfast, the spirited girl rode her sex toy bicycle to school, enduring forced orgasms under the gaze of classmates on the road. 

The newly joined male classmate of the study group, who also commuted by bicycle, guided the girl to park her sex toy bicycle in a more hidden old parking spot. 

Then the girl came to the multi-purpose classroom to begin the study group's daily morning "exercises". Stripping off her uniform in front of the male classmates, the girl felt greatly ashamed again. 

On the girl's naked body, like yesterday, were wrapped bright hemp ropes and lewd words written all over. 

This was tied and written on by the girl after her morning bath, following the master's orders. 

As compensation for not participating in the public toilet humiliation yesterday, the girl had to serve as a "urinal" for the study group members today like yesterday. Under simple restraints, the girl was quickly bound in an even more perverted posture than yesterday. 

Her legs were not only pressed to the sides of her body, but her knees were pressed behind her shoulders, with both ankles crossed and bound above her head. 

Her arms were folded back to hug her thighs, with both wrists bound behind her back. 

The girl had been restrained in this posture by the new teacher before, but now combined with the "urinal makeup" on her body, the level of perversion increased exponentially. 

Her completely exposed groin, with the diamond-shaped area formed by bright red hemp ropes, perfectly highlighted her three holes. 

The pose of hugging her legs back looked like deliberately displaying the lewd inviting words on both thighs. 

Hugging her legs back also forced the girl to thrust out her chest. 

On her chest was naturally the small sign saying "Free Meat Urinal", and since this was a study group activity, the girl's signature was also next to the "Free Meat Urinal" text. 

The girl had practiced specially this morning before writing... 

But the male classmates only noticed the literal meaning of the neatly written words. Amid waves of mockery, they took out their large penises one after another, taking turns using the girl as a urinal to relieve their desires. 

At the same time, the study group also truly had a learning function. 

While two male classmates were using the urinal girl's body to vent their desires, another male classmate had already taken out notes to ask the girl questions, forcing the honor student girl to try hard to explain difficult course material while orgasming in both holes. 

Compared to the depressing pleasure of being used completely as an object, now the dual identities of honor student and urinal being used simultaneously produced a huge contrast, generating humiliating pleasure with a level of stimulation no less than yesterday. 

So the girl immediately fell into unstoppable dual orgasms both physically and mentally! 

But the study group members were completely different from yesterday's park managers. 

Already familiar with the girl's three exceptional lewd holes, plus long-term training, the male classmates' thrusting was not only more violent, but also more prolonged. Besides this, they were also crueler to the girl. 

Yesterday's park managers didn't know the girl at all. To them, just striking perverted poses in a public toilet, and even being able to use the urethra for intercourse, the girl's level of depravity was already beyond imagination. 

But the male classmates had witnessed even more perverted behaviors from the girl. In their minds, the girl was simply a huge masochistic pervert who orgasmed more the more she was abused! 

So the male classmates not only showed no mercy when g@ng-raping the girl, but would also come up with various cruel humiliation games from time to time. 

As a result, after orgasming to incontinence from violent r@pe in her vagina and anus, emptying her urine, the girl's bladder was immediately filled with two loads of semen in succession. 

Two male classmates deliberately switched to inserting into her urethra to ejaculate after their final thrusts. The girl keenly sensed their purpose. But the girl was just a mere urinal. Even understanding the masters' cruel intentions, she could only accept gratefully... 

Next the male classmates were very in sync. No matter whether they had been thrusting in the girl's vagina, anus, urethra or even mouth originally, they all ultimately ejaculated into the girl's bladder. 

Additionally, among the male classmates was that newly joined one. 

The male classmate who joined the study group last Monday, besides pointing out a more hidden old bicycle parking spot to the girl, of course also participated plenty in the study group's "morning exercise" benefits. 

But he quickly discovered that having just joined, he was a bit out of his depth. 

Not knowing the surrounding male classmates had also trained up on the girl's body, his thrusting time couldn't match their endurance. His penis going soft after just two ejaculations made him feel quite unsatisfied. 

Lacking physical ability, he could only make up for it with intelligence. 

On his first day joining the study group he had participated in deflowering the girl's urethra. On the second day he had witnessed the chemical and mechanical torture composed of chili sauce, toothpaste and motorized sex toys. Firmly believing the "girl is a masochist", he was suddenly struck by an evil idea. 

The girl was now a "meat urinal" - not just "meat", but also a "urinal". And this male classmate, after his penis went soft, happened to need to urinate... 

Just as another male classmate was straddling the restrained girl's body to violently r@pe her urethra, this male classmate rushed to get under the girl first. 

The others hadn't figured out his purpose in occupying the girl's lower body when his penis was only half erect, but the study group members were all polite good students. Since he had gotten there first, no one objected. 

Next everyone saw him forcibly spread open the girl's anus with his fingers, then stuff his half-erect penis into the girl's rectum, then order the girl to clench tight. 

First he was painfully squeezed by the girl. The girl's anus had astonishing contractile force from long-term training, and the half-erect penis simply couldn't resist. 

But as he frowned, the girl was even more startled, her eyes opening wide in fear. 

The penis inserted in her anus wasn't fully erect, which the girl noticed immediately of course. 

Early in the summer vacation, the leader and others would often blindfold the girl, forcing her to identify each person by the large penis violently raping her body. If she guessed wrong she would receive cruel sexual punishment. After many times, the girl had actually gradually mastered this perverted game... 

Now the girl's three holes between her legs had become more and more sensitive under training. She could even identify each study group member's erect large penis. 

Of course, if they wanted to use the excuse of the girl not being able to identify a large penis to punish her, it wasn't difficult. After putting on an enhancement sheath, even if the girl's vaginal walls were more sensitive, it would be impossible to identify the large penis through the thick plastic... 

But this insertion of a half-erect penis was a new experience for the girl. 

Then, the half-erect penis began spraying large gushes of warm liquid inside the girl's rectum. 

Her sensitive rectal walls made the girl immediately realize this force of spraying definitely wasn't ejaculation. 

Combined with the continuous spraying of warm liquid, the clever girl immediately understood - this half-erect penis was actually urinating inside her rectum! 

Not expecting the master to do this, the girl was frightened at first. Then, the girl quickly accepted it. 

Already completely dominated by masochistic consciousness from the urinal humiliation and restrained g@ng r@pe, the girl immediately thought that accepting the master's urination was actually the true purpose of her as a urinal... 

Her self-worth being further lowered, plus the warm full feeling in her rectum, also slightly increased the girl's mental pleasure again. 

"Clench tight, don't let it leak out." 

After truly urinating, the male classmate didn't forget to order the girl to tighten her anus, before pulling out his half-erect penis that had been painfully squeezed. 

"You didn't..." 

Another study group member who was originally friends with this male classmate had already noticed what this male classmate had just done. 

After being surprised, he was also excited: "So it can be played like this, I'll do it too!" 

The girl whose mouth wasn't gagged not only didn't beg for mercy at all, but when the male classmate stuffed that half-erect penis reeking of urine into her mouth, the girl even carefully licked and sucked the large penis clean after urination, to thank the master for not despising her, this dirty secondhand urinal... 

The other male classmates whose large penises hadn't softened at all also got playful. 

Even the leader's younger brother and the two teachers who arrived midway also forcibly inserted their large penises into the girl's anus one after another, squeezing out urine even if they didn't have the urge. 

At first, the girl only felt a bit of fullness, but under everyone's successive urination enemas, soon the feeling in the girl's intestines became the swelling pleasure of forced expansion. 

Moreover, the g@ng r@pe continued. While the girl's intestines were continuously filled with urine, the continuous filling of her bladder with semen didn't stop! 

By the time the homeroom teacher reminded everyone it was almost time, both of the girl's excretory organs had been forced into a swollen state urgently needing release. 

But when undoing the girl's restraints, the masters actually still stuffed electric huge rods into the girl's three holes between her legs, with no intention of letting the girl release at all! 

Even though she had experienced continuous semen filling of her bladder before, that was only during her first urethral r@pe, when the masters curiously released under the strange stimulation of the urethra. 

At that time, after the big g@ng r@pe, the girl didn't need to continue enduring the urge to urinate. 

But now, not only was the girl's bladder excessively backfilled with thick semen, her intestines were also simultaneously filled with a large amount of fresh urine, even making her lower abdomen swell up. 

Yet the masters wouldn't let her excrete, and even made her attend class in this state! 

Moreover, the masters showed no mercy to the girl at all, or rather they simply hadn't considered it, actually forcibly stuffing three huge rods into the girl's three holes between her legs as usual. 

When the spiked huge rod was forcefully stuffed into her anus, the warm urine originally filling her rectum was immediately all pressed into her colon, further intensifying the swollen feeling in her intestines! 

But this still couldn't compare to how terrifying the wolf fang huge rods stuffed into her vagina and urethra were. 

Moreover, the vaginal canal behind the bladder was also stuffed with a huge rod. The vaginal huge rod was pressed by the anal huge rod behind it, further pressing forward on the bladder, making the girl's poor urine storage organ suffer cruel internal and external double compression! 

The violent urge to excrete and equally violent sexual stimulation ravaged the girl's fragile nerves simultaneously, making even the girl with astonishing endurance unable to help but hug her abdomen. 

The girl's waist was very slender. Originally just the huge rods inside her body were enough to create bulges on her lower abdomen. 

Now with her body filled with a large amount of liquid, the bulges of the huge rods could no longer be seen on the lower abdomen the girl was hugging with both hands, because it had already been directly filled to swelling! 

Fortunately the girl's school uniform wasn't form-fitting, so her swollen belly like early pregnancy could still be hidden under the uniform. 

The terrifying physiological need made the girl involuntarily look at the master with pleading eyes. 

Unfortunately, after yesterday's training, the girl had further established her status as a "meat urinal" in her heart. 

Just like a lifeless toy, the girl actually didn't even dare to beg for mercy... 

But the masters didn't notice the girl's change. The girl didn't speak up, so they just assumed she didn't object. 

So the cruel masters not only activated the vibration, twisting and rotating functions of all three huge rods simultaneously, but also spread open the girl's hands to slap and play with her belly that was swollen like a water bag! 

Though the masters didn't use much force, and the nine functions of the three huge rods were only at the lowest setting, the girl was still stimulated to the point of being unable to hold back her screams and wails. 

Fortunately the multi-purpose classroom originally had soundproofing, so the girl's miserable cries didn't attract any attention... 

Including her masters, who also didn't notice just how much pain she was in... 

So, in this state of extreme swelling, the girl was brought back to the classroom to begin class. 

Of course, the remote-controlled teasing in class didn't stop. 

The huge rod in her vagina was like usual, with three mechanical stimulations making her entire vaginal canal from cervix to G-spot to opening simultaneously erupt in violent pleasure, forcing the girl into mandatory orgasms! 

The huge rod in her intestines was also like usual, with the rectum constantly erupting in intense pleasure, giving the girl continuous excretory pleasure! 

Though it wasn't the first time being stuffed with an anal huge rod in an over-enema state, the large amount of liquid blocked in her intestines unable to be released and constantly stirred by the anal huge rod brought the girl a swelling pleasure that was equally unbearable! 

Under the huge contrast, the blockage, swelling and excretory pleasure were further amplified simultaneously! 

Moreover, thinking that what was in her belly now wasn't water but urine made the girl constantly aware of her urinal identity. 

But being in class, surrounded by mostly unaware classmates, also made the girl constantly maintain her honor student self-awareness. 

Another huge contrast, greatly elevating the girl's sense of humiliation as a meat urinal, further triggering mental shameful orgasms! 

At the same time, her urethra suffering similar sex toy stimulation and blockage made the triple pleasure of blockage, swelling and excretion similar to her anus amplify again! 

Moreover, what was stored in the girl's bladder wasn't urine, but a large amount of much thicker semen. 

The huge rod directly stuffed into her bladder stirred, its twisting shaft and rotating glans making the long soft spikes drive the large amount of semen to flow inside the girl's bladder. The thick semen quickly spun at the same high speed as the electric huge rod. The semen vortex in her bladder constantly stimulated her hypersensitive bladder walls, bringing the girl another kind of cruel strange pleasure! 

The terrifying stimulation made the girl unable to maintain even her usual blank face. Her tightly furrowed brows and hands lightly pressing her belly made her classmates easily see the girl was "very uncomfortable". Only the study group members who knew the truth knew the girl wasn't uncomfortable, but rather the opposite - "too comfortable" to be showing that kind of pained orgasm face... 

The male classmates controlling the various remotes, seeing this expression on the girl, only wanted to make the girl "more comfortable"... 

Before long, not only were the three huge rods inside her body pushed to full function, but even the powerful vibrating eggs clipped to her nipple rings and clitoral ring were turned to maximum power, giving the girl on the verge of collapse another all-round pleasure attack! 

In the classroom, only one study group member didn't have a remote control, but this didn't mean he couldn't play with the girl. 

As usual, a complex problem was written in the center of the blackboard. When the homeroom teacher asked if any student would volunteer to solve it, the girl had to very cooperatively raise her hand on her own. 

The girl who seemed to be working hard to solve the problem in front of her was actually enduring the homeroom teacher's cruel sexual play on her lower body hidden behind the wide teacher's desk. 

Not only was her lower abdomen violently grabbed and pressed, but the homeroom teacher pretending to turn around to watch the girl solve the problem used his other hand to directly push aside the girl's panties and grab the fully functioning huge rod in her vagina to thrust violently! 

Because the girl was really too short, her lower body was completely hidden by the teacher's desk, so until she finished solving the problem, about to lose consciousness from orgasm, her body's abnormality still wasn't discovered by the unaware classmates. 

The vaginal huge rod viciously struck her cervix, her already soaked panties were pulled back into place, and the girl who had just come back to her senses from the silent violent orgasm could finally drag her trembling legs back to her seat, continuing to listen with difficulty to the homeroom teacher's lecture under the sexual abuse of sex toys all over her body. 

Even when class ended,the girl couldn't find any relief because the master had already given orders. 

After reassuring concerned friends that there was nothing wrong with her body, the girl still had to head to the abandoned rooftop of the school building." 

"In the restroom, quickly restrain oneself into the form of a human toilet with simple leather cuffs, waiting for the master's use."
