Chapter 19 The Girl's Descent into Urethral Training
After much torment, the girl's urge to urinate finally broke through its limits. However, though her urethral sphincter had relaxed, the urine was still blocked by the metal rod in her urethra.
The shop owner controlled his strength well, keeping the urethral plug just short of fully entering the bladder through the urethra.
Without the force of the urethral contraction, the small ball at the tip of the urethral plug, surrounded by smooth urethral walls on all sides, began to be gradually pushed out of the girl's urethra by the urine in her bladder.
Feeling the object in her urethra about to be squeezed out, the girl panicked and quickly clenched her urethra again. But her bladder, already out of control, was also contracting to expel the urine. The small ball, once again tightly gripped by the urethral walls, only slowed its movement but didn't stop.
Just as the ball was about to be pushed out, it was forced back in by a tremendous force - the shop owner had returned to the girl's lower body.
The shop owner pushed the small ball deep into the girl's urethra again, then let the urine push it out, repeatedly thrusting the ball in and out of the girl's urethra this way.
The constant pain from her urethra finally broke the girl's will to resist. She entrusted her hope of holding in her urine to the urethral plug, letting her full bladder and the shop owner's arm struggle against each other.
The urethral sphincter completely relaxed. Though the flesh walls still tightly gripped the small ball at the tip of the urethral plug, preventing urine from passing, the pain it caused the girl was much reduced.
Giving up on holding her urine, the girl's attention shifted to the foreign object in her urethra.
The pain had lessened, replaced by another strange stimulation. Though the thrusting motion was the same, the sensation was different from her esophagus, vagina and intestines, which had also been penetrated by foreign objects many times. This fourth type of penetration pleasure made the girl curiously want to feel more.
Her eyes followed her attention downward. She saw the shop owner crouching between her widely spread legs, but the girl's attention was drawn to something else.
Her expression became panicked again as the girl realized in horror that behind the owner was the entrance to the sex shop.
Only now did the girl realize that all her lewd behavior in the store could actually be clearly seen from outside!
Through the glass door and display window, the girl saw that besides the five men led by the leader, there were quite a few people standing outside watching.
Compared to earlier when she had openly orgasmed in the mall, there were far fewer onlookers now - just a few groups of two or three people. But they were all men, and their gazes and expressions all uniformly revealed blatant obscene lust.
In fact, the sex shop's location was somewhat special, on a small side street. The other end of the side street was an emergency exit not normally used.
Besides this sex shop, the only other store on the small street was a shop specializing in renting and selling pornographic films, making this small street a well-known seedy area.
Because of this awkward situation, even if people noticed onlookers gathering here, they wouldn't come over to join the crowd.
The only ones who would actually come were those who were similarly lecherous and unashamed to admit it.
Though the girl had walked into the sex shop herself, she had been in such an extreme mental state when entering that she hadn't paid any attention to her surroundings. So until now, the girl still thought the area outside the sex shop was the busy mall corridor.
Thinking she was performing lewd acts in front of the public again, shame and humiliation made the girl not dare to let her gaze linger outside the store.
But when her gaze returned inside, the girl discovered that the couple who had been in the store earlier were now standing in a corner out of sight from outside, intently watching her shameful state up close.
The shop owner also noticed the girl looking around frantically. But being familiar with the surroundings, he had deliberately positioned the girl facing the store entrance from the start. From the beginning, the shop owner had no intention of interrupting the exposure training the girl was receiving.
The reduced resistance from the urethral plug told the shop owner the girl had given up resisting.
Though the female body before him was young, she had clearly undergone intense "training" and was in an aroused state. It was the perfect opportunity to develop her urethra.
Though the urethra and anus were both excretory organs, the anus had a similar capacity to the vagina. People curious about sex naturally treated the anus as a second sexual organ.
The shop owner wasn't an expert in this area, but he had some knowledge. Now that he had the chance, he of course wanted to put it into practice.
He changed from gentle thrusting to stirring motions. The girl's attention was immediately drawn back to the strange movements in her urethra.
The urethral walls, which had never touched a hard object before, were forcibly spread open by the hard metal ball, letting the girl experience a novel third type of stretching.
At first, the metal ball truly only brought sharp pain to her tightly clenched urethra. But after her urethra relaxed, the pain quickly lessened.
Moreover, her full bladder was urgently seeking release. The foreign object in her urethra also brought a constant feeling of excretion.
The girl had experienced enemas, squirting, and stretching of both holes many times. Her masochistic tendencies had long since been forcibly trained.
After the sensations of pain, fullness, excretion and stretching mixed together, they formed a new sexual stimulation for the girl.
Furthermore, the girl's vagina and anus had already been excessively developed. They were still constantly ravaged by two huge rods, giving the girl massive amounts of pleasure at all times. Her aroused body made the new sensations from her urethra grow rapidly.
Restrained and not even allowed to beg for mercy, the girl could only despairingly realize that her urethra seemed about to become another perverted hole that would make her body orgasm when men toyed with it at will.
Though the shop owner knew the girl didn't approve of developing her urethra, her body honestly reflected that she was gradually experiencing pleasure from it.
The girl's transformation encouraged the shop owner. He gradually increased the amplitude of his stirring with the metal rod, and began thrusting again.
Deeply understanding how fragile the urethra was, the shop owner carefully controlled his strength, gradually intensifying the stimulation to the girl's urethra without increasing her discomfort.
The girl's hands, restrained to the chair back, tightly clenched into fists. Her trembling body twisted uneasily. The stimulation to her urethra reminded the girl of when her anus first began to be played with.
Back then, she had thought orgasming from anal play was perverted behavior. But at some point, she had become a perverted woman who would play with her own anus to orgasm...
The small ball in her urethra began thrusting faster. The girl suddenly steeled her resolve, deciding to resist. She absolutely could not let herself become a perverted masochist who enjoyed having her urethra played with!
Her muffled cries suddenly increased. The men, knowing the girl was about to reach her peak of pleasure, lightly pressed a few buttons on the remote control.
The girl's cries rose even higher. She felt the vibration, rotation and twisting of the two huge rods in her vagina and anus suddenly intensify. A violent flood of pleasure suddenly surged forth.
The double vibration in both holes of course strongly stimulated the flesh walls tightly gripping the rods. The resonating vibrations penetrated through the girl's thin internal structure, making even the urine filling her bladder churn.
The particles on the counter-rotating rods ground against every sensitive spot on her delicate flesh walls. The flesh wall between her two holes was pulled in opposite directions. Combined with the counter-twisting of the two rods striking the middle flesh wall as if beating each other, it erupted in terrifying tearing pleasure.
Moreover, the large twisting motions of the two rods forced the girl's delicate vagina and rectum to constantly change and distort shape inside her body. This unimaginable abnormal churning not only violently impacted the girl's sexual senses, but also brought external compression to her full bladder again.
The girl's uterus, which should have been most protected, not only had its cervix tightly pressed and ground by the vibrator below, but was also squeezed from front and back by the string of balls in her anus and her urine-distended bladder.
This three-sided attack put intense pressure on her uterus. It also made the girl's sensation of having three holes forcibly stretched by two huge rods and the urethral plug mix with the violent urge to urinate blocked in her bladder, combining into a frenzied stimulation that filled her entire abdomen.
The girl's hands pulled at the chains on her leather handcuffs. Her feet, cuffed at the thighs, kicked erratically.
The sexual fluids that had been constantly flowing from her vagina now sprayed out from the gaps around the vibrator.
Her convulsing, trembling body made the metal nipple rings tightly gripping her nipples sway as well. Her clitoris, which had long since pushed out from under its delicate skin, quivered excitedly.
Her cherry-red aroused flesh became even more engorged, turning an even deeper shade of red. The girl's hypersensitivity increased further.
The shop owner of course also noticed the changes inside the girl's body. Even without hearing the mechanical sounds from between her legs grow louder, he could see the girl's obvious orgasmic reactions.
He also noticed another inconspicuous abnormality - what he had thought was just the girl's slightly plump waist now showed strange undulations.
Only later did the swelling of her bladder make the girl's lower abdomen bulge slightly overall, looking at first glance like the belly fat common in women.
But the experienced shop owner could tell from the strange movements of the girl's lower abdomen that the objects inside her seemed even larger than he had initially imagined.
Curious, the shop owner finally grabbed the girl's leather panties and slowly pulled out the huge rods from her two holes.
The girl's struggles intensified again. The two huge rods rampaging inside her body being slowly withdrawn didn't slow her orgasm. Instead, it added a sense of release to her compressed lower body.
Moreover, the sensation of the large spheres of the anal beads stretching her anus as they were pulled out one by one gave the girl, who was being forced to hold in her urine, an abnormally confused stimulation.
The two huge rods slowly withdrawing from the girl's body slightly surprised the shop owner. After pulling out the two rods, the girl's lower abdomen immediately caved back in, revealing her slender, beautiful waist.
He hadn't expected such huge objects to be inserted into the small female body before him. It seemed the physical training this girl had undergone was even more intense than he had imagined. In that case, his gentle actions earlier may have been overly cautious.
The onlookers were also shocked by the two huge rods at the same time. The girl didn't know about the commotion outside the store, but the gasps from the couple inside made her feel utterly ashamed.
Having these two grotesquely shaped huge rods pulled out of her body in front of everyone, they would surely all think she was a hopelessly perverted, depraved woman...
The two huge rods were still moving mechanically. The shop owner was just curious. After looking at the two rods, he immediately inserted them back into the girl's body.
But the resistance he encountered surprised him. He hadn't expected this girl, who was stuffed with such huge rods and undergoing exposure training, to still have such tight holes like a young virgin.
Of course, the girl's strength in clenching her two holes was no match for the shop owner's arm strength. The urge to urinate that had eased slightly after the rods were removed surged forth again from her compressed bladder as the two wet, huge rods were reinserted.
Having further grasped the extent of the girl's training, the shop owner decided to give her even more intense stimulation.
Deliberately pressing on her bladder to pressure the girl, the shop owner wanted to use more extreme methods to make her quickly succumb to the pleasure from her urethra.
His other hand controlled the small ball at the tip of the metal rod, probing and stirring inside her urethra. The girl, already under multiple stimulations, suddenly shuddered as she felt another special stimulation.
The strange stimulation puzzled the girl. Meeting her confused gaze as she looked down at her lower body was the shop owner's evil smile.
The metal rod shook forcefully. The girl's gagged mouth immediately let out a cry of anguish.
Her nipples were tightly gripped by metal nipple rings. Her vagina, anus and urethra were all penetrated by terrifying sex toys. But the girl still had one most sensitive place that hadn't been targeted - her clitoris, which had long since become erect and peeked out on its own.
Though it hadn't been directly stimulated, the girl felt an strange, immense stimulation coming from her clitoris.
The reason was the urethral plug in the shop owner's hand, stimulating her clitoris from inside through her urethra. Another of the girl's weak points had been discovered. The shop owner immediately launched a focused attack.
The small ball teased her sensitive clitoris from the inside. The hand pressing on the girl's lower abdomen also went on the offensive. His palm still pressed on her bladder, but his fingers extended to above her labia, then quickly swept back and forth.
The girl's utmost efforts to endure finally collapsed. Unbelievable, terrifying stimulation exploded wildly from her clitoris. Moreover, her nipples, vagina, anus, urethra and even bladder - six places in total - all transmitted irresistible stimulation to the girl. Her well-trained endurance was finally completely shattered by the violent pleasure exceeding her limits, triggering a tsunami-like extreme orgasm.
Her out-of-control limbs pulled at the chains on her restraints, but couldn't relieve even a bit of the pleasure. Her defenseless body remained under intense stimulation.
The vaginal and rectal walls, instinctively clenching as hard as possible during orgasm, squeezed the huge rods invading her two holes. But this only made the hard particles on the rods embed themselves more tightly. The rods' oversized volume had already stretched out the folds in her flesh walls. Now the deeply embedded particles on the rods rotated, pulling at every sensitive nerve.
The small ball in her urethra was tightly wedged in the middle. Not a drop of the surging urine could leak out. Her swollen bladder, pushed by the hand pressing on her lower abdomen, sent urgent demands to urinate to her brain. But her fully aroused body incorporated even this into her pleasure.
The small ball in her urethra was precisely controlled, constantly teasing at specific spots.
The labia spread open by the huge rods were entirely within range of the fingers' rapid rubbing above her urethra. This caused the covered part of her clitoris to be constantly pressed, while the exposed part received direct, continuous stimulation. The cruel pleasure exploding from her clitoris continued to soar.
The girl's rationality, on the verge of destruction, was jolted awake by a flash.
Her originally unfocused, blank gaze regained focus. Her fearful eyes saw that one of the onlookers outside the store was holding a professional camera. Camera flashes kept going off. Many others were also filming with their phones that didn't flash.
Her convulsing, twisting body not only made the bright nipple rings tightly gripping her nipples sway, but also caused her white shirt to completely fall open.
Her chest and groin were fully exposed to public view. Her lewd body performed a perverted urethral orgasm. Even from the girl's own angle, she could see the clear fluids spraying from her vagina scattering in the air.
The restrained girl could only despairingly allow the crowd to film such an unspeakably obscene scene. But her repeatedly distorted instincts transformed even this unbearable immense shame into sinful pleasure, triggering a shameful orgasm in her mind that rivaled the intense physical stimulation of the moment!
Though her expression couldn't be clearly seen through the dark lenses, the constantly overflowing tears and strings of thick saliva trailing from the holes in her ball gag, combined with the spraying sexual fluids and even her jumping waist and alternately spreading and clenching fingers and toes, made the girl's entire body exude an obscene aura.
In the shop owner's eyes, the girl's frantically struggling body had not yet reached its limit. Though surprised by her extraordinary endurance, the shop owner had no intention of stopping. Instead, he grew even more curious to explore further.
Outside the store, the onlookers held their breath as they admired the girl's lewd state. Listening to the girl's muffled cries through the phone, the men, once again intoxicated by sadistic urges, cruelly took out the remote control for the two huge rods inside the girl's body. They pressed down on several upward-pointing triangular buttons.
The girl's body, which had been struggling in the chair held down by the shop owner, suddenly tensed up. The forcibly prolonged orgasmic frenzy seemed to have no end...
