Anna was a vibrant young 25 year old girl with a beautiful body. Long straight blonde hair, full lips, gorgeous 34-C breasts, and long toned tanned legs. She was applying for an advanced executive position with her company that would involve large amounts of stress for extended periods of time. As part of the application process and before it would even be considered she was required to submit herself for a complete physical examination with her usual GP and then receive a referral for a specialized examination. She received that examination a week ago and was given her referral. She really didn't know what she was getting herself into. She was instructed to open the information packet exactly 1 week before the scheduled appointment. That was today.

Inside the folder was the instructions for the exam prep.

"Mandatory Preparation for Orgasm Tolerance test:

The purpose of this exam is to test the patients natural reactions to high levels of stress. This is simulated by keeping the patient in an extremely high state of sexual arousal for an extended period of time.

The patient must refrain from any sexual activity for at least 1 week prior to day the exam is to take place. This includes masturbation of any kind.

The patient is required to completely shave or wax all pubic hair the night before the exam.

The patient should empty their bladder before reporting for the exam.

The patient should arrive at the facility at least 30 minutes early."

Anna thought this test sounded more than a bit out of the ordinary but she had been to the test facility before for x-rays and a MRI so she knew everything would be very professional. Getting the job was her dream and she could really use the huge paychecks she would be getting. She decided to follow the directions and comply with everything that was being asked of her. Refraining from all sexual activity wouldn't be so hard for her since it had been a while since she had a boyfriend because of her current work schedule and she didn't masturbate that often anyway. The day of the exam came. Her appointment was set for 10 am.

She woke up at 9 am. She decided to take a quick shower before getting dressed and leaving for the appointment. She made sure she removed all pubic hair and then put on a nice pair of boy short underwear from Victoria's secret and a matching bra. On top of that she threw on one of her favorite skirts and a nice blouse and her normal dress shoes that she wore each day to her office.

She arrived at the facility exactly at 9:25. She wrote her name down on the clipboard and took a seat in the waiting room. The orderly quickly called her over to the counter to confirm her information and that she had followed the required prep for her exam. She answered all the questions and was told she would called in in a few minutes. She then returned to her seat and started reading a magazine.

A few minutes later a very attractive young brunette nurse opened the door and called her name.

She was taken in to a small exam room that looked exactly like the ones at her regular GP. There the nurse asked again if she had followed the prep instructions and took her vital signs, height of 5'7 and weight of 115 lbs. After confirming that everything was normal and that she was ready for the procedure the nurse, who said her name was Gina, asked Anna to completely remove her clothing and put on a gown with the opening in the back and that she would be back in a few minutes.

Anna complied and was quickly completely naked with only the skimpy gown on. She took a seat on the examination table and waited for Gina to return.

It was not long before Gina opened the door again.

"Good I see that you are ready for the exam to take place. I must warn you that while at the beginning you might find the procedure pleasant you will find that after a while it feels like pure torture. Unfortunately the point of this examination is to cause as much sexual frustration as humanly possible. We do this by stimulating your genitals until you almost reach orgasm over and over, but without actually giving you enough stimulation to have an orgasm. That's the easiest way to simulate extremely stressful situations."

Anna thought to herself: "Great now I remember why I hate going to the doctors."

Gina then led Anna to a larger examination room just down the hall in an area separate from where she remembered the x-rays and MRIs taking place. In the room she saw all sorts of medical equipment such as EKG machines, ultrasound machines, and a gyno chair a normal flat examination table. The two of them were only in the room for a few seconds when two more people entered the room. One was also dressed like a nurse and the other wore a doctor's coat. They too were young female doctors who looked like they could attract quite some attention at the local bar. They identified themselves as Dr. Denise Hudson and nurse Donna Forham.

Anna was seated on the exam table with her gown still on when Dr. Hudson came up to and shook her hand.

"Hello, I am Doctor Denise Hudson. I will be conducting the examination on you today. Let me give you some quick background as to what we will be doing today. We have designed this examination to simulate an extremely stressful situation for your body. We do that by putting you in a state of severely heightened sexual arousal by providing sexual stimulation in a variety of ways but not allowing you to come to a climax for an extremely extended period of time. Nurses Donna and Gina will be here to assist me. I must apologize in advance to you for any discomfort we may cause you today. Unfortunately if you do have an orgasm at any point during the exam any of the data we collect will be voided and either your application will be rejected or we may have to attempt the exam on you again at a later date. This is most unlikely as we all are extremely experienced and qualified at this procedure. But I must advise you to let us know if something is too much."

Anna thanked her and asked her to be more specific as to what the procedure will involve.

"Well first of all I am going to ask to you to remove your gown and lay down flat on the exam table. Then nurse Gina will apply a special KY-oil to your genital area that is designed to heighten sensitivity and cause initial sexual arousal. A specialized computer sensor and data recorder will then be put inside your vagina just on top of your cervix to measure any vaginal contractions and record your vaginal secretion levels. You will also be hooked up to a heart monitor and at various times an ultrasound may be conducted to see exactly what's going on in your body. The nurses are here to assist with that part and also observe your reactions. 3 different kinds of stimulation will then applied to your genital area and vagina by me over the course of the next 3 hours, with each taking place uninterrupted except for a short break in between forms of stimulation and of course to allow the urge to orgasm to subside. You are asked to advise when this is required and also to resist the urge to orgasm for as long as possible. The first form of stimulation will be completely manual with a gloved hand, followed by special electrodes, and then finally with a vibrator. The point is to give your body a variety of proven methods in order to collect better data. Unfortunately you will not be allowed to have an orgasm at any point during this procedure even when it is completed because of the required observations. If you feel you can't stop your self from moving please let us know and restraints can be used if required. Do you have any questions?"

Anna thought this was a most unusual medical test but the science seemed sound. She knew this would probably be very unpleasant and embarrassing but she felt the same way about most medical exams and procedures. She nodded that she did not.

"Well then let us begin. Please remove your gown and toss it to the side and then lay down flat on the table."

Anna complied and was now completely naked with her body flat and straight on the table. She watched as all the doctors put on latex exam gloves.

"Nurse Gina would please apply the oil to Anna's vaginal area and Nurse Donna please hook her up to the EKG but keep the sound very low, we don't want annoying noises distracting us or our patient. Anna if you could spread your legs just a little bit."

Anna watched as Gina put some of this mystery oil on her gloves and Donna put the EKG patches on her chest.

"Alright Anna this oil takes a minute or two to take effect but you should feel a slight burning sensation and possibly an immediate spike in your sexual arousal level." Gina said.

All the medical talk had really turned off Anna's brain and she was not at all aroused at this point. That changed when she felt Gina's hand touch her vagina. Gina spread the oil on her outer genitalia and then changed her gloves.

"Let's give that a few minutes to start taking effect and then we can get started." Dr. Hudson said.

Anna could feel all the blood rushing to her genitals and the oil had certainly peaked her interest. She couldn't wait for the testing to begin now.

"Gina please insert the probe and make sure it is working properly. Anna you might feel some pressure and possibly some minor cramping because of how deep this probe has to go. Please put your feet together and keep your legs flat."

The probe was no larger than a small ball and went inside smoothly. Gina made sure it went all the way in and Anna could feel it touching her cervix. It was a little unconformable. She looked over to see Gina looking at the data the wireless probe was providing on a computer screen. Although she couldn't see the screen very well it looked like a lot of information.

"Anna I forgot to tell you the other function of that probe. Gina has the ability to manually prevent you from achieving orgasm by activating an electrode on the top of that probe. It will send a shock directly to your cervix that will be quite painful although there would be no long term damage. Of course it is a complete last resort but it will prevent an unfortunate accident from messing up our test results."

"Alright I think everyone is ready here. Donna keep an eye on her heart rates and Gina on her reactions and the computer data. Remember to record your observations. Start the timer for 1 hour. Anna you will feel me starting to stimulate your genital area. Please try to remain as still as possible throughout this exam."

"Remember, Anna, keep fighting it," Dr. Hudson's voice was calm and professional, a stark contrast to the storm brewing between Anna's legs. Anna's eyes snapped open, and she stared at the doctor with a mix of desperation and determination. Her hips began to rock slightly against the doctor's hand, and her breathing grew ragged. The doctor waited, timing her touches with the peaks of Anna's arousal, pushing her ever closer to the edge but never quite allowing her to tip over.

"The sensitivity of your g-spot increases with every contraction, sending more blood flow to your clitoris and intensifying the pleasure," Dr. Hudson continued, her voice a soft murmur, almost soothing in the starkness of the clinical room. "Your vaginal walls are tightening around my fingers, preparing for what they believe will be an orgasm." She paused for a moment, her thumb hovering over Anna's clit. "But we must ensure your body can handle this level of stress without giving in. That's the true measure of your tolerance. Can you please describe to us exactly how you are feeling at this point in our procedure?" Dr. Hudson asked as she paused with her flat palm covering the whole of Anna's vulva in a momentary pause.

"It's... it's unbearable," Anna managed to croak out, her voice strained and thick with desire. She felt her body was on fire, each nerve ending in her genital area pulsing with electric need. "I'm so close, but I'm trying to fight it... trying to stop myself from orgasming..." Her words trailed off into a series of moans as she bit her lip, trying to distract herself from the intense arousal that was threatening to consume her.

"Good, very good," Dr. Hudson said with a nod to the nurses. She turned to Gina, who was monitoring the data. "What are we seeing?"

Gina's eyes remained glued to the screen as she responded, her voice professional but with a hint of excitement. "Her heart rate is up significantly, and the vaginal contractions are becoming more frequent. The ultrasound is showing increased blood flow to the clitoral area and the vaginal walls are tightening around the probe. She's definitely in a state of high arousal."

Dr. Hudson nodded thoughtfully. "Anna, remember what I said earlier about thinking of something mundane, like baseball or school, to distract you from the pleasure? We need you to keep doing that. The purpose of this exam is to see how well you can manage stress, and the stress of not being allowed to climax is a significant part of it. Try to focus on something else entirely."

Her voice was calm and steady, but it was clear she understood the torment she was putting Anna through. Anna took a deep, shaky breath, her body quivering with unreleased tension. She closed her eyes and thought of the last boring training seminar she'd attended at work. The room was silent except for the low beep of the heart monitor and the sound of her own erratic breathing.

After what felt like an eternity, Dr. Hudson's hand began to move again, her fingertips dancing along Anna's inner labia. The sudden absence and then return of stimulation was almost too much for Anna to handle. She could feel her body screaming for release, but she gritted her teeth and focused on the tedium of workplace policies and procedures.

"You're doing well, Anna," Dr. Hudson said, her voice a gentle coaxing. "Just a little more."

Anna's eyes snapped open and she took a deep, trembling breath as the doctor's hand once again stopped moving. She could feel the edge of her orgasm receding slightly, like a wave pulling back from the shore before it crashes down. Her entire body was taut with unfulfilled need, her legs shaking and her chest heaving.

"Your vaginal contractions have reached their peak, Anna," Dr. Hudson said, her voice a mix of professionalism and something else – perhaps admiration. "But remember, we can't let you cum. That would invalidate our results, and you will not pass this accessment."

Anna nodded, her eyes squeezed shut tightly. Her body was one giant nerve ending, each beat of her heart echoing through her swollen clit, her pussy aching for a release that was perpetually denied. She focused on the coolness of the table beneath her, the sterile smell of the room, anything but the fiery pleasure that was being teased from her body.

"Good," Dr. Hudson said, her voice a gentle caress in the silence. "Now, we will move on to the second phase of the exam."

The doctor's hand withdrew from Anna's trembling body, and she felt the sudden absence of the exquisite torture. She lay there, panting, her legs quivering as she tried to calm herself down. Dr. Hudson looked at her with a professional smile, as if they'd just finished a routine check-up instead of pushing her to the brink of orgasm and then denying it to her.

"Alright Anna, we're going to take a five-minute break now. This will allow your body to reset a bit before we proceed with the next phase. Remember, the goal here is to maintain your composure and resist the urge to climax. Think of something that relaxes you, or perhaps something mundane from your workday so that you may maximize this break and bring yourself back down before we start the next part."

Dr. Hudson stood up and removed her gloves, walking over to the computer where Gina had been watching the monitors. She tapped the screen. "Donna, would you go over all the readings from phase one with me, please?"

Donna nodded, her eyes never leaving the screen as she began to recite the data in a calm, measured tone. "Heart rate maxed out at 165 beats per minute, with a consistent peak during each near-climax. Vaginal contractions were strong and regular, with secretion levels increasing significantly. The ultrasound showed a clear engorgement of the clitoris and the labia majora and minora."

"Excellent," Dr. Hudson murmured, making some notes on a clipboard. "It seems the oil is working as expected." She turned her attention back to Anna, who was still panting lightly on the table. "Now, Anna, before we proceed with phase two, I want to commend you on your performance so far. Your ability to communicate and resist is vital to the success of this test."

Nurse Donna took over, her voice a soothing monotone as she began to recite the sensor readings. "During the initial manual stimulation, the patient's vaginal secretions increased by fifty percent. Heart rate fluctuated between one fifty to one seventy beats per minute, with the highest peak at one fifty-eight during the most intense moments of arousal. The ultrasound showed significant blood flow to the clitoral area, with the clitoral glans appearing swollen and sensitive to touch."

Anna lay there, listening to the technical jargon and trying to ignore the throbbing need between her legs. The cool air of the room felt like a slap on her overheated skin, a stark contrast to the heat and friction Dr. Hudson had been building within her.

"Anna, I noticed that the g-spot sensor readings spiked dramatically during the manual stimulation," Dr. Hudson said, her voice breaking through the haze of Anna's thoughts. "Could you tell us more about how you felt when I was pressing on your g-spot?"

Anna took a deep breath, trying to compose herself. "It felt... intense," she managed to say, her voice a hoarse whisper. "It was like my entire body was focused on that one spot."

"Was it painful at any point?" Dr. Hudson inquired, her gaze sharp and focused.

Anna swallowed, her throat dry. "No, not painful. Just... intense. It felt like the pleasure was building and building, but it never quite reached a peak."

Dr. Hudson nodded thoughtfully. "That's precisely what we're looking for. The g-spot can be quite sensitive, and your body's response is essential data for our research. Now, let's prepare for phase two."

The doctor gestured to Gina, who wheeled over a tray of medical equipment that looked more suited to a sci-fi movie than an ordinary exam room. On it were several small pads with wires attached to them, and a device that looked like a cross between a dildo and a vibrator, and a control box with a digital display.

"Now, Anna," Dr. Hudson began, her voice soothing despite the clinical nature of the situation, "for phase two, we're going to introduce some electrical stimulation. These pads will be placed at key points around your vagina and clitoris, providing a controlled amount of current that will intensify your arousal without causing pain. This device is specifically designed to provide a controlled amount of stimulation to the key parts of your vaginal area that will heighten arousal the most. The other part of this device is an insertable probe that we will use to intensify the internal sensations. It will also cause you to experience genital contractions similar to those during orgasm which will trick your body into thinking it's right about to climax. That is why it is so important to do your best to resist those urges, whatever it takes. We will of course continue to do our part in monitoring your reactions to prevent that climax from occurring."

Anna's eyes widened slightly as she watched Dr. Hudson pick up the small, round pads. They were sticky on one side, and she could see the tiny wires connected to them. The doctor's gaze was professional, but there was a hint of understanding in her eyes that made Anna feel slightly less embarrassed.

"First, we're going to place this pad here," Dr. Hudson said, pointing to the top of Anna's mons pubis. "It will be right above your clitoris, but it won't make direct contact. The purpose is to create a sort of... echo effect, amplifying the sensations without overstimulating the area."

Anna felt the coolness of the pad stick to her skin as Gina carefully applied it. Dr. Hudson's explanation was thorough and precise, which helped to ease her nerves slightly.

"Next, we're placing this one here," Dr. Hudson said, indicating the base of Anna's vaginal opening. "This will help us monitor the contractions of your pelvic floor muscles as the arousal builds. And this one here," she continued, placing the third pad on Anna's inner thigh, "will be used to deliver a mild shock if needed to prevent an accidental orgasm. It's a fail-safe measure, but we'll do everything we can to avoid using it."

Gina nodded in agreement as she attached the remaining pads around Anna's labia. The coldness of the metal made Anna's skin tingle, and she felt a thrill of anticipation mixed with trepidation.

"The sensation from the pads will be quite different from my manual touch," Dr. Hudson explained, picking up the vibrator-like device with a detachable probe. "The electrical current will be a pulsing sensation, starting out quite faint and gradually increasing in intensity. It's designed to keep you on edge without pushing you over the brink."

Anna felt a slight tremble in her legs as the doctor began to attach the device to her. The anticipation was almost unbearable as the cold metal of the probe was gently inserted into her. She took a deep breath as Dr. Hudson connected the final pad and switched on the machine. A soft, rhythmic buzz filled the room, and Anna felt a gentle pulsing against her clitoris and inner walls. The feeling was foreign, yet somehow exhilarating. She couldn't help but let out a small gasp as the doctor adjusted the settings.

"The pads will start to warm up and the vibrations will become more noticeable," Dr. Hudson assured her, watching her intently. "Your body might want to react automatically, but remember, you need to stay in control. If it gets too intense, let us know."

As the current began to pulse through the pads, Anna felt the sensation increase, sending waves of pleasure through her body. It was unlike anything she'd ever felt before—almost as if her body was being teased by an unseen force. The vibrations grew stronger, and she could feel the muscles in her pelvis tightening, her breath hitching in her throat.

"Remember, the sensation will intensify," Dr. Hudson said, watching Anna's face closely. "But you must stay in control. We need to gauge your limits, so don't be shy about telling us when it becomes too much."

Anna nodded, her eyes wide with anticipation as the doctor began to fiddle with the controls. The initial sensation from the pads was a gentle warmth that spread through her skin, soon turning into a soft, pulsing tingle that grew stronger as the seconds ticked by. The vibrations grew more intense, and she could feel her clit swelling, begging for more direct contact. She bit her lip, fighting the urge to squirm as the doctor's voice remained calm and professional.

"Good, Anna. You're doing excellent," Dr. Hudson said, her tone reassuring. "The pads are designed to mimic the sensation of a partner's touch, but the real magic comes from the probe. It will induce contractions that feel like the beginning of an orgasm, but we'll adjust the settings to prevent you from actually climaxing."

Nurse Gina nodded, her eyes glued to the monitor as the data began to spike. "Her pulse is rising, but she seems to be managing the initial sensations well."

Dr. Hudson nodded, her gaze still fixed on Anna's reactions. "Good, Donna, let's increase the intensity of the pads by 10 percent."

The pulsing grew stronger, the warmth spreading deeper into Anna's core. She felt her hips start to move slightly, the muscles in her thighs tightening. "It's getting intense," she whispered, her voice strained with effort.

"Just keep breathing, Anna," Dr. Hudson said, her voice a soothing contrast to the building storm of sensation. "How are her stats looking?" she asked, glancing over at the monitors.

Nurse Gina checked the readings. "Her heart rate's up, but within safe parameters. The vaginal probe is showing strong contractions, but she's not at the peak yet."

Dr. Hudson nodded, pleased with Anna's endurance so far. "Good. Let's increase the intensity of the pads by another 10 percent. Gina, keep a close eye on her vitals."

Nurse Gina made the adjustment, and immediately, Anna felt the warmth spread further, the pulsing more insistent. She gripped the sides of the exam table, her knuckles turning white. "Oh, god," she murmured, her breath coming in short gasps.

"Anna, I need you to focus," Dr. Hudson said firmly. "Tell me what you're feeling. Describe the sensations for me."

Anna took a deep breath, trying to find the words to describe the maelstrom of pleasure and frustration swirling within her. "It's like...like my body is on the edge of a cliff, and it wants to jump, but I'm holding it back." She panted, her eyes squeezed shut. "It feels so good, but it's...it's just out of reach."

"Very descriptive, Anna," Dr. Hudson said, her own eyes focused on the monitors. "Can you be more specific about the sensations in your genital area? It's crucial for the accuracy of our data."

Anna took a deep, shaky breath, her cheeks flushing with both arousal and embarrassment. "It feels...like my clit is being teased by a feather, but it's also being pinched gently. And inside, it's like...like someone's fingertips are lightly stroking the inside of my vagina, but they're not...quite...enough."

Dr. Hudson nodded thoughtfully. "Good, Anna. That's exactly the kind of detail we need." She leaned closer, her own face a mask of professional detachment. "Now, I'm going to insert the probe to add to these sensations. Try to stay as still as possible. The more you move, the more your body will want to climax. We need to see how long you can resist. Can you please part put your feet together and let your knees fall open?"

Anna did as she was asked. While she had been lying down comfortably before she now had her legs butterflied open to give Dr. Hudson the access to her vaginal area she needed to be able to manipulate the insertable probe.

The probe slid in smoothly, and the instant it did, the pulsing grew stronger, the sensation more intense. It was as if a switch had been flipped, and Anna's body was now a live wire, the electricity coursing through her veins, pooling in her core. She whimpered; her hips thrust slightly momentarily at the moment of insertion then relaxed again.

"Excellent," Dr. Hudson murmured, watching the monitors intently. She began to manipulate the probe with a slow, rhythmic motion that sent waves of pleasure through Anna's body. The young woman's legs began to shake, and she bit her lip to keep from crying out. The sensation was exquisite, but the knowledge that she couldn't give in to it was a constant throb in the back of her mind.

The doctor's eyes never left the monitors as she twisted the probe slightly, eliciting a gasp from Anna. "Tell me, Anna, how does that feel?"

"It's...intense," Anna replied through gritted teeth. "It's like...like you're...fingering me...but not...not all the way."

Dr. Hudson nodded, her eyes flicking between the monitors and Anna's face. "Good. Now, I need you to focus and tell me when you feel something more than just the probe inside you. We're looking for a spot that feels different, more sensitive."

Anna took a moment to center herself, her eyes squeezed shut as she focused on the sensations building inside her. The probe's movements grew shallower, then deeper, as Dr. Hudson explored her vaginal canal with clinical precision. Anna's body responded in kind, her breath hitching in her throat, her hips moving almost imperceptibly to match the rhythm of the probe's strokes.

"I think... I think it's... right there," Anna gasped out, pointing with a trembling hand to a spot just above where the probe was currently resting. Dr. Hudson nodded, her eyes never leaving the monitors.

"Nurse Gina, could you please come over and palpate Anna's abdomen and vulva to locate the tip of the probe externally?" she requested calmly. "I am curious as to where exactly her g-spot is located so that we might record it for future analysis."

Gina nodded and approached the table, her gloved hands hovering over Anna's trembling stomach. She applied gentle pressure, her fingers moving in slow circles as she searched for the probe's telltale shape beneath the skin. Anna's breathing grew ragged as the anticipation of Gina's touch heightened her arousal even further. She felt the nurse's fingertips graze her clit, the light pressure sending a jolt of pleasure through her body.

The monitors beeped rapidly, alerting the doctor to the impending climax. "Gina, stop," Dr. Hudson said sharply, her eyes on the readings. "Anna, you're getting too close. You need to bring your arousal down. I know I am putting a lot of pressure on you but you need to put your mind elsewhere while we do this. I need you to against these sensations and this arousal and bring yourself back down. I don't wish to have to use the emergency shock pad to keep you from going over the edge."

Anna's eyes snapped open and she nodded, her cheeks flushed with embarrassment. She took several deep breaths, trying to think of something, anything, that would take her mind off the exquisite pleasure she was experiencing. The doctor's stern voice brought her back to reality. "Ok, I can do this," she murmured to herself, focusing on her breathing and trying to relax her taut muscles.

As the next minute or two ticked by, the doctor and nurses observed her intently. Anna felt a mix of mortification and determination. She didn't want to be seen as weak or incapable, not when this job was her ticket to a better life. So, she closed her eyes and imagined herself in the most boring, non-sexual situation she could think of—sitting through a five-hour long conference call with her colleagues discussing the company's latest quarterly reports.

Her heart rate gradually decreased, and the beeping of the monitors grew steadier. Dr. Hudson nodded in approval. "Good job, Anna. I know it's difficult, but we're collecting invaluable data here."

Gina gently touched the inside of Anna's thigh, her gaze professional yet empathetic. "Doctor, I believe we can proceed with the manual verification of the probe's placement."

Dr. Hudson nodded curtly. "Very well. Nurse Gina you may resume your palpation on her externally for the location of the tip of this probe, I believe we are out of the danger zone now."

Gina's hand was gentle but firm as it began to trace the crevice between Anna's thighs. She was meticulous, her fingers moving with precision as she felt for the probe's exact location. Anna couldn't help but gasp slightly as Gina's touch grazed over her clitoris, the sensation sending a jolt through her body. She clenched her fists, willing herself to stay focused and not succumb to the waves of pleasure threatening to crash over her once more.

The room was quiet except for the steady beep of the heart monitor and the occasional murmur of professional discourse between Dr. Hudson and the nurses. Anna felt exposed and vulnerable under their scrutiny, but also oddly aroused by the situation. It was a strange mix of medical sterility and erotic tension, one she had never experienced before.

Gina's slender fingers moved in slow, deliberate circles around Anna's mons, the gentle touch sending ripples of anticipation through her body. Each pass of the nurse's hand brought her closer to the precipice of pleasure, but she held firm, her eyes tightly shut as she continued to think of the most mundane things she could imagine. The sensation of Gina's touch grew more intense, and Anna could feel her body responding, her breath quickening and her muscles tightening around the probe Dr. Hudson was using inside her.

Finally, after what felt like an eternity, Gina's fingertip brushed against the protrusion of the probe just beneath her skin. Anna's breath hitched, and she bit her bottom lip to keep from crying out. The nurse's touch was feather-light, but it sent a jolt of pleasure through her, making it all the more difficult to remain composed.

"I believe I've found it," Gina announced, her voice calm and professional.

Anna felt a cold sensation as Dr. Hudson pulled the probe out slightly, then pushed it back in with a bit more force. The doctor's eyes were glued to the computer screen, her brow furrowed in concentration. "Good, now I need to measure the depth of your g-spot from the vaginal entrance."

The probe was withdrawn until it was almost entirely out of her, then pushed back in with a firm but measured motion. Anna winced at the suddenness of it, but the pain was quickly overridden by the intense pleasure that accompanied it. She could feel the probe's smooth surface pressing against the spot that seemed to hold the key to her climax. Dr. Hudson was meticulous, sliding the probe in and out, each movement sending a pulse of arousal through her body.

"Please, Anna, try to keep still. We need an accurate reading," Dr. Hudson instructed, her voice steady despite the evident excitement of her patient's body.

Anna nodded, her cheeks flushed and her chest rising and falling rapidly. She focused on the rhythmic sound of the heart monitor, using it as a beacon to anchor herself in the sea of sensation. The probe was withdrawn once again, the coldness of the room contrasting sharply with the warmth of her own arousal. When it was reinserted, it hit that perfect spot with a precision that made Anna's toes curl. The doctor was measuring the depth of her g-spot from the entrance of her vagina, her movements calculated and precise. Anna's entire being was focused on the delicate dance of frustration and pleasure playing out between her legs.

The doctor's eyes never left the computer screen; her brows furrowed in concentration as the probe's depth was meticulously recorded. Anna could feel the tension in the room thicken as the doctor's gloved hand moved in and out of her, the latex a stark reminder of the clinical nature of the procedure. Yet, the sensations were anything but clinical; they were raw and intimate, a stark contrast to the sterile environment.

The probe's tip grazed her g-spot with each entry, sending ripples of pleasure through her core. She bit down hard on the soft pad in her mouth, her eyes watering from the effort of not giving in to the sweet release that danced just out of reach. She could feel her body's natural response, the walls of her vagina clenching around the probe, begging for the final push over the edge.

"Donna, note the depth," Dr. Hudson called out, her voice a mix of professional detachment and the thrill of discovery. "It's at exactly 2.7 inches from the vaginal entrance."

Anna felt a strange sensation of vulnerability as the exact measurements of her most intimate spot were being taken. Yet, the doctor's voice remained calm and collected, as if discussing a simple blood pressure reading. The nurse nodded, her eyes on the computer monitor, noticing the spike in Anna's vitals with every shallow thrust of the probe.

"Now, let's see if we can keep you at this level without letting you climax," Dr. Hudson said, her voice a mix of challenge and curiosity. With the probe in place, she began to work it in a way that was both scientifically calculated and eerily similar to a lover's caress. The sensation grew more intense with each stroke, and Anna could feel the pressure building in her lower abdomen.

Her eyes shot open, and she gripped the sides of the exam table. "Please," she gasped, "I can't...I can't take it anymore."

Dr. Hudson looked up from the computer, her gaze meeting Anna's desperate stare. She nodded to Gina, who leaned in closer, her hand poised over the probe controls. The sensation grew stronger, the pressure against Anna's g-spot increasing in a way that felt almost personal. It was as if the doctor knew exactly where to touch her, how much to touch her, to keep her balancing precariously on the knife's edge of pleasure without letting her fall over.

"Bear with us, Anna," Dr. Hudson said, her voice soothing yet firm. "Your response is exactly what we need. You're doing so well."

Anna's eyes squeezed shut as the probe inside her began to pulse, the rhythm mimicking the relentless throb of an approaching orgasm. Her body was a taut bowstring, and she could feel the tension building with each stroke. The doctor's thumb, resting gently on her clit, applied just enough pressure to keep her hovering on the precipice.

The electrical impulses from the probe grew stronger, and her vaginal muscles responded with involuntary contractions. Anna's breathing grew erratic, her chest heaving with each gasp. She felt her walls tightening around the probe, as if trying to clench onto something solid in the sea of sensation. On the monitors, the graph lines danced wildly, illustrating her body's desperate fight against the oncoming climax.

The doctor's eyes remained on the computer, her brow furrowed as she studied the data. "Your vaginal muscles are contracting beautifully," she commented, her voice cool and clinical. "But remember, Anna, you need to resist."

Anna's breath was coming in short, sharp bursts now, her body a battleground between the need for release and the doctor's command to hold back. She could feel her core tightening around the probe with each pulse of electricity, her hips bucking involuntarily against the unforgiving table. The sensation was unbearable, a mix of pleasure and frustration that seemed to be consuming her from the inside out. No matter how hard Anna tried to fight back the electricity kept forcing her vaginal muscles to rhythmically convulse almost as if she was orgasming without the climax or release of pleasure that came with an actual orgasm.

On the screens beside her, the monitors told a tale of arousal that was almost painful to behold. The lines spiked with every contraction, a visual representation of the war raging between her body's instincts and her will. Dr. Hudson's gaze flickered between the monitors and Anna's face, noting every twitch and quiver with the detachment of a scientist studying a particularly fascinating specimen. Her own hand remained poised, thumb pressing steadily against Anna's clit, keeping her trapped on the edge of ecstasy.

"Anna, I need you to be as descriptive as possible," Dr. Hudson said, her voice calm and collected. "Tell me what you're feeling. Is the pressure building?"

Anna nodded, her eyes squeezed shut. "It's like...like there's a coil inside me, tightening and tightening, but it never...it never...oh God, it's so frustrating."

"Good, keep going," Dr. Hudson said, her voice as calm as ever. "Describe it more. How intense is the sensation? Can you feel your pelvic muscles spasming?"

Anna bit her lip, her voice strained. "It's like...it's like a knot, getting tighter and tighter, but it won't unravel. It's intense, really intense." Her pelvis arched slightly off the table as the probe within her continued its relentless rhythm, each pulse sending waves of pleasure crashing against the dam of her self-control.

Dr. Hudson nodded, her expression one of focused curiosity. "And the sensation in your pelvic muscles? Are they twitching?"

"Yes," Anna gasped, her hands clenched into fists at her sides. "They're...they're spasming. It feels like I'm going to cum...but I can't..."

Dr. Hudson nodded, her eyes never leaving the monitors. "Tell me more, Anna. What does that feel like, exactly?"

Anna's face was a picture of tormented pleasure. "It's like...like there are fingers inside me, playing with me, but they never let me come. It's...it's driving me crazy." Her voice was a mix of desperation and resentment.

"Excellent," Dr. Hudson murmured, the assistant nurses writing notes on her clipboard. "And your frustration level?"

"It's unbearable," Anna whimpered, her body a canvas of need. "It's like...like there's a storm in my head and my body, but no release. It's like...like I'm trapped in an endless cycle of want and need."

Dr. Hudson nodded, "Thank you Anna. I want to take a chance here and give you one more absolute peak using this set up before we move on. Nurse Gina, would you please set a stopwatch starting right to now to see how long it takes her to reach the absolute edge before we take another quick rest period and move on to the final segment of the accessment. Anna the long it takes for me to bring you to that absolute edge the better your final results will be so I'm going to ask you again to fight back against me and these sensations as long as you can. Do whatever you have to do to hold back from that edge as long as you can."

Nurse Gina nodded and held up a stopwatch. "Ready, doctor."

"Proceed," Dr. Hudson said, her eyes still on the monitors.

Anna felt Gina's hand gently part her folds, the cool gel contrasting with the heat building within her. The probe began to pulse faster, the vibrations stronger, and the doctor's thumb pressed down more insistently on her clit. Anna's body responded immediately, her hips bucking upwards, desperately seeking relief. Her breathing grew ragged as she stared at the ceiling, trying to find something, anything, to focus on other than the exquisite torture unfolding between her legs.

The room was silent except for the rhythmic pulse of the probe and the soft beeping of the monitors. Anna's eyes rolled back in her head as she felt the pressure inside her mount. She had never felt so close to the edge without falling over, her body a tightly coiled spring threatening to snap.

With every beat of the probe, she could feel her orgasm build, a crescendo of pleasure that seemed never-ending. She tried to think of work, her favorite TV show, even her least favorite food—anything to distract her from the relentless stimulation. But her body had a mind of its own, and it was screaming for release. She bit her lip hard, hoping the pain would help ground her, but it only served to make her more aware of the throbbing ache between her legs.

"Come on, Anna, you can do this," she whispered to herself, her eyes squeezed shut. But it was a losing battle. The pleasure was too intense, too overwhelming. The doctor's thumb was a merciless force, stroking and teasing until she was sure she could take no more.

"Alright, you're doing great," Dr. Hudson said, her voice calm and professional despite the intimate nature of her task. "We're going to increase the intensity now. Remember, you need to hold back for the sake of the test."

Her thumb circled Anna's clit with a renewed vigor, pressing down with a firmness that made it impossible to ignore. Anna felt her body responding, her hips bucking slightly against the table. The probe inside her was now pulsing in a way that felt almost cruel, sending waves of pleasure through her that she knew were designed to push her to her limit.

"Nearly...there...just...a...little..." Anna panted, her voice strained as she felt the orgasm build up inside her. Dr. Hudson's eyes never left the monitors, watching the lines spike and dip with each contraction of Anna's muscles. She was a maestro conducting a symphony of frustrain and pleasure, and Anna was her instrument.

"Your vaginal contractions are strong, Anna," Dr. Hudson noted, her voice a mix of scientific curiosity and a hint of approval. "Keep it up. The longer you can resist, the better the data."

Anna felt the doctor's words as if they were a personal challenge. She gritted her teeth and dug her nails into the padding of the exam table, focusing on the pain in her fingertips to combat the exquisite pleasure coursing through her body. The probe's tempo increased, its vibrations now a deep, insistent throb that resonated in her very core. Gina and Donna watched her reactions with professional detachment, their eyes on the screens before them, their fingers poised to make adjustments as needed.

Suddenly, the monitors beeped more rapidly, their lines shooting upwards in a frantic dance. Anna's body tensed, her muscles clenching around the probe as if trying to expel it. She threw her head back and screamed, her voice raw with need.

"I can't hold it! It's too much! Please, I can't do it!" she begged, her eyes squeezed shut as sweat beaded on her forehead.

Dr. Hudson's eyes remained glued to the monitors, her expression unchanging. "Just a few more seconds, Anna. We need to get the maximum readings."

Finally, the imminent orgasm alert triggered on the monitors and the fail-safe immediately kicked in and stopped all the electrical stimulation instantaneously preventing Anna from orgasming at the absolute last second.

Anna's body went almost immediately limp, and she let out a huge sigh as the edge of orgasm was pulled right out from underneath her. She had gone all the way there even with her doing everything she could to avoid that precipus.

"Excellent job Anna, I could really tell you were doing your absolute best to hold back that edge as long as possible. I'm so sorry we had to pull the proverbial rug out from under you like that." Dr. Hudson with a little humor in her voice. "Gina, how long did Anna make it on our little timer there, I'd like to compare it to our last test subject from last week."

Gina checked the stopwatch in her hand. "It was 2 minutes and 43 seconds doctor. Quite an impressive performance, she held it back well. That is, I believe 41 seconds longer than our patient last week."

"Wow that is impressive Anna! You seem to excellent self-control indeed." Dr. Hudson said in a positive tone. "I am curious: what were you doing to maintain your control so well? What was your process exactly? I've had a few patients that seemed to have no resolve at all and didn't even make it 30 seconds when we get to that section of the accessment."

Anna took a moment to catch her breath before she replied, "Well, I tried to focus on something non-erotic like my niece's birthday party, and I kept thinking of my work deadlines to keep myself from getting too carried away." She was surprised that she had lasted so long.

Dr. Hudson nodded, impressed. "That's a very effective technique. Now, we need to move on to the next phase of the exam, which is the vibrator stimulation. It will be even more intense than before. Remember, your goal is to stay as close to the edge as possible without actually reaching climax."

Anna took a deep, shaky breath, feeling a mix of excitement and dread. "Okay, I'll do my best," she murmured, her voice hoarse from her earlier screams.

The doctor nodded and patted her thigh gently before removing the probe and the pads. "Good, now let's give you a five-minute break to relax and recover before we move on to the next phase." She turned to Gina and Donna. "Let's review the data from the second phase. We need to ensure everything is in order before we proceed."

Anna sat up slowly, the cool air of the room hitting her sensitive skin. She took deep breaths, her chest rising and falling with each inhale. She slipped off the exam table and stepped over to the chair in the corner, feeling the tension in her legs as she sat down. The room was quiet except for the low hum of the medical equipment and the occasional beep from the heart monitor. She watched as Dr. Hudson, Gina, and Donna huddled around a computer, discussing the graph lines and numbers displayed on the screen. The sight of them in their professional attire, so focused on the data, was almost surreal given the intimate nature of what had just occurred.

Her mind raced with the events of the last few minutes. The pressure of the probe, the shocking sensation of the electrode pads, and the relentless stimulation had pushed her to the brink of orgasmic release so many times she'd lost count. Yet, she had held back, driven by a strange mix of determination and the desire not to disappoint the doctor. Her body was still thrumming with arousal, and she felt a dull ache in her clitoris from the constant attention it had received. Despite the discomfort, she knew she had to keep her mind sharp for what was to come.

The medical team remained huddled around the computer, their eyes darting back and forth between the screen and their notes. Anna took the opportunity to sip some water from the cup on the side table, feeling the cool liquid soothing her dry throat. She glanced at the clock on the wall, watching the seconds tick by as she tried to compose herself. The sight of the vibrator lying on the tray next to her brought a fresh wave of anticipation. It resembled a toothbrush, looking somewhat familiar but certainly not something she had ever used.

As the hushed tones of the doctor and nurses filled the room, she couldn't help but listen in on their conversation. They were discussing her arousal patterns, the effectiveness of the probe, and the consistency of her vaginal contractions with a clinical detachment that seemed almost cold. Yet, Anna found the objectivity of their discussion surprisingly comforting. It reminded her that she was in a professional environment, and that her participation in this bizarre exam was contributing to something significant.

"Her contractions are strong and regular," Dr. Hudson murmured to Gina, pointing at the graph on the screen. "The data from the probe indicates she's approaching peak arousal right here (Gina pointing to something on the screen in front of them), but she's managed to maintain control admirably."

Anna took a deep breath, trying to ignore the warmth spreading through her body at the memory of their conversation about her intimate responses. It was strange to think that her body's reactions to pleasure were being dissected so clinically. Yet, the professionalism of the team was a comfort, a stark contrast to the raw, carnality of the situation. She took another sip of water, feeling the coldness of the plastic cup against her lips and the wetness of her mouth.

Gina looked over at her with a nod of approval. "You're doing great, Anna. The break is almost over. Just remember, we need to keep pushing your limits. Your job could depend on it." The nurse's voice was soothing, but there was an underlying steeliness to her tone that told Anna she wasn't kidding.

Anna nodded, taking one final deep breath before Dr. Hudson began discussing the next phase. "We're going to use this device now. It's designed to simulate the most intense form of sexual arousal by focusing directly what is most commonly the most erogenous area in the female body: your clitoris. It's completely safe, but it can be quite overwhelming," the doctor explained, her voice a calm counterpoint to the rising tide of tension in the room.

Dr. Hudson explains that based on past experiences for this phase she will be strapped down to the medical table this time with her hands restrained over her head and her legs butterflied open like before due to the intensity of the stimulation in this section and the tendency for subjects to want to buck and thrash. As she explains the set up for this section she briefly picks up the vibrator from the tray of instruments and Anna gets a better look at it. It is white with a pink top that almost looks like an electric tooth brush. Dr. Hudson says that it has three speeds and is called an "Eroscilator."

Anna is helped into position and her wrists are secured to the table. She watches as Gina and Dr. Hudson prepare the vibrator with more of the oil. The doctor applies it to her clitoris and then slides it down the length of her vagina, pausing briefly at her g-spot before pulling it out and placing it back on her clitoris.

"Are you ready to continue?" Dr. Hudson asks with a firm but gentle smile.

Anna nods, gulping down a deep breath. She steels herself for the intense stimulation she knows is to come.

"I'm ready, doctor," Anna says, her voice a mix of determination and apprehension.

"Very good," Dr. Hudson responds, her voice calm and professional. "We're going to start the vibrator on the lowest setting and gradually increase the intensity. Remember, it's crucial for the data that you resist climax."

Anna nods, her eyes squeezed shut as the hum of the vibrator fills the room. The coolness of the metal against her sensitive skin sends a shiver down her spine, and she feels the beginnings of a new wave of arousal building within her. The doctor starts with slow, gentle strokes, the vibrations sending delicious pulses through her entire body. Anna focuses on her breathing, trying to keep her hips as still as possible despite the growing urge to grind against the device.

"Remember, Anna, keep your body as relaxed as you can," Dr. Hudson instructs, her eyes glued to the monitors. "Your body will want to tense up as you get closer to climax, but it's unfortunately important that we only build the frustration. We will keep a close eye on the readings from the monitors on how your body is holding up and I will also be looking for the involuntary vaginal contractions that you have right before climax to make sure we don't accidentally go over that edge, but you have to do your part to fight it back as well. This last part of the procedure is often found to be the most difficult for my patients based on their feedback I'm afraid. I'm not sure if it's because of the increased focus specifically on the clitoris or because of the compound effect of the previous two segments, but you might find this one and even greater challenge. Our last patient was cursing my name at the top of her lungs by the end as if I were some sort of sadist, but I assure you my intent in these procedures is purely scientific and for the benefit of you if you get this job. We designed these tests to make sure only a physically qualified candidate gets the position."

Anna nods, bracing herself for the increased stimulation. Dr. Hudson starts the Eroscilator at the lowest setting, and the sudden sharpness of the new sensation sends a soft buzz through Anna's body. She gets goosebumps for a moment as she tries to keep her breathing even as the intensity slowly builds. The vibrations feel heavenly against her sensitive skin, and she can feel the pressure building deep within her core.

"The Eroscilator was chosen for this exam because it's designed to provide very precise and intense stimulation," Dr. Hudson explains calmly, her voice a stark contrast to the rising tension in the room. "Other vibrators might be too broad or too shallow in their effect, but this device targets the clitoris directly and can be controlled in a way that allows us to keep you right at that edge for as long as necessary."

"It's got various speed settings and patterns that we've found to be the most effective for this kind of testing. We've studied the neurological responses, and the muscular contractions associated with the buildup to orgasm, and this tool gives us the most reliable and repeatable results. Plus, it's medical-grade, which means it's safe and sterile for the procedure."

Anna nodded, taking a deep breath as Dr. Hudson manipulated the Eroscilator in small circles around and over her clitoris. Anna could already tell that Dr. Hudson was a master at teasing her clitoris, and it wasn't just because she was also a woman. At first, it was just a faint buzz against her sensitive skin, the cool plastic gliding over her clit in a delicate, almost tickling manner. She felt a shiver run through her body but remained still, focusing on the doctor's words. Gina and Donna observed intently, noting every twitch and gasp in their charts. The room was filled with the low hum of the vibrator and the rhythmic beeping of the heart monitor, which grew steadily faster as the minutes passed.

The sensation grew more intense as the circles grew smaller, the vibrations more focused on her clit. Anna's breathing quickened, and she began to feel a warm, pulsing need building deep within her. She squeezed her eyes shut, trying to think about anything else—her job, her cat, the office supplies she needed to order. But it was no use; the feeling grew too intense. She was so close, her thighs quivering, her toes curling.

"Your vitals are rising nicely, Anna," Dr. Hudson said, glancing at the monitors. "We're approaching the plateau we need for the next phase."

Anna nodded, her teeth gritted in anticipation. The vibrations had become a constant, insistent throb against her clit, and she could feel the beginnings of an orgasm building in her core. But she knew she had to hold back. She took deep, steadying breaths, trying to ignore the slickness between her legs and the desperate ache for release.

Then, Dr. Hudson did it. She hit the button on the Eroscilator, and the vibrations grew stronger, the buzz becoming a deep, resonant pulse that seemed to echo through Anna's entire body. The doctor's hand didn't falter, the plastic toy continuing its relentless dance over her swollen flesh. Anna's back arched, her hips lifting off the table, but the restraint held her in place. She let out a low, animalistic groan, the sound ripped from her chest as the sensation grew sharper, more insistent.

Her eyes flew open to find Dr. Hudson watching her intently, her own face a mask of professional scrutiny. "Remember, Anna," she said, her voice calm, "We need to collect data at the peak of your arousal. Try to hold off as long as possible."

The doctor's words barely registered as the Eroscilator's intensity grew. Anna's vagina clenched, a sign of an impending climax, and the heart rate monitor beeped frantically in response. Dr. Hudson's eyes flickered to the monitors before returning to Anna's face, her expression unreadable. With a swift move, she withdrew the device just as Anna felt the crest of pleasure about to break, her hips thrusting upward as if to chase after the device. The sudden cessation of the vibrations was almost painful, leaving her body poised on the edge of an orgasm that never came.

The room was silent except for Anna's ragged breaths and the persistent beeping of the heart monitor. She stared up at the ceiling, her eyes wide and unfocused. Dr. Hudson nodded to Gina, who quickly made some notes on the clipboard. "Good," the doctor said, her voice devoid of any inflection, "Your body's reaction is exactly what we need."

Holding the still buzzing Eroscilator in her latex-gloved hand, Dr. Hudson allowed Anna a brief respite. The cool air against her overheated skin was a stark contrast to the intense sensations she had just experienced. Anna took a deep, shuddering breath, trying to calm her racing pulse. She could feel the doctor's gaze on her, assessing, calculating. The anticipation was almost as potent as the stimulation itself.

Without warning, Dr. Hudson reapplied the device, this time with more pressure. The vibrations rippled through Anna's clitoris, sending shockwaves of pleasure through her body. She bit down hard on her bottom lip, trying to stifle a moan. The doctor's eyes narrowed, watching her every twitch and quiver. Anna's body arched off the table, the restraint straps digging into her wrists and ankles.

"Remember, Anna, you must resist," Dr. Hudson said firmly, her voice cutting through the haze of pleasure. "We need to know just how much your body can handle before you can be considered for this position."

Anna nodded, gritting her teeth as the doctor once again brought the Eroscilator back into play. The vibrations grew stronger, more insistent, and Anna felt her body begin to quiver uncontrollably. She focused on the pain of the restraint straps, the coldness of the straps digging into her skin, anything but the overwhelming pleasure that was threatening to consume her. Yet, it was as if her body had a mind of its own, her hips moving in time with the rhythmic pulses of the device.

Time seemed to stretch out as Dr. Hudson pushed her further and further, each touch bringing her closer to the edge of climax. Anna could feel the muscles in her stomach tighten and her toes curl as she fought against the wave of pleasure that was about to crash over her. Just when she thought she couldn't take it anymore, the vibrations ceased again, leaving her gasping for air.

"Very good, Anna," Dr. Hudson said calmly, noting the readings on the monitors. "Your body is responding well to the stress. Let's continue this for a while." Dr. Hudson said as if she was ignorant to the fact that she was basically torturing the poor young blonde by forcing her to the absolute edge over and over again without stopping.

The doctor resumed the relentless onslaught of pleasure, her eyes never leaving Anna's body as she worked the device with precision. Anna felt the heat rising in her cheeks, a mix of embarrassment and frustration. She couldn't believe she was in this situation, but she knew that if she could just hold out a little longer, she might get the job. The thought of the job's financial rewards was the only thing keeping her from screaming in pleasure and frustration.

The vibrations grew stronger, and Anna felt her body start to convulse. She could feel the orgasm building, her muscles tensing and releasing in a delicious dance that was both agony and ecstasy. She squeezed her eyes shut and thought of her grandmother's knitting patterns, trying to focus on anything other than the exquisite torture being inflicted on her.

"Your vaginal contractions are increasing, Anna," Gina announced calmly from the corner of the room, her eyes glued to the monitor. "Your body's trying to reach climax, but remember, you must resist."

Dr. Hudson nodded in acknowledgment and leaned in closer to Anna's genitals. She gently pushed aside the Eroscilator, her eyes widening slightly as she observed Anna's pink folds quivering with need. Her gloved thumb brushed the outside of Anna's vagina, noting the involuntary spasms that accompanied her internal struggle.

"Anna, I'm going to need you to try and hold back again," the doctor instructed, her voice firm but gentle. "Think of it as a marathon, not a sprint. Your body's natural instinct is to climax, but you must fight it."

The young woman took a deep breath, feeling the cool air brush against her overheated skin. She nodded, gritting her teeth. The doctor replaced the Eroscilator, the vibrations once again penetrating her core. The intensity was unbearable, each pulse pushing her closer to the edge. She felt like a live wire, ready to snap at any moment.

"Think of the job," she murmured to herself, focusing on the prize at the end of this bizarre and erotic ordeal. She could feel her heart pounding in her chest, the EKG beeps speeding up in time with the vibrations. The doctor's hand was unrelenting, guiding the device in a rhythm that was driving her wild.

The minutes dragged on, each one feeling like an eternity. Anna's hips began to move of their own accord, the need for release becoming more than she could handle. "I... I don't think I can," she gasped, her voice trembling.

"You're doing very well, Anna," Dr. Hudson reassured her, her own voice a mix of professional detachment and something else—was it fascination? "Your body is responding exactly as we anticipated."

Anna's breath came in shallow, rapid bursts as she stared at the ceiling, trying to think about anything but the delicious torture her body was enduring. She felt a bead of sweat trickle down her neck, pooling between her breasts. Dr. Hudson's kept the Eroscilator dancing around her clit, never quite touching it directly, keeping the pressure just shy of what would send her spiraling over the edge.

"Your body is doing so well, Anna," Dr. Hudson said, her voice calm and measured. "Your heart rate is elevated, your vaginal walls are contracting beautifully. Just keep fighting it."

Anna's eyes were squeezed shut as she bit down on her bottom lip, the pain in her wrists from the restraints the only thing keeping her grounded in reality. The vibrations grew stronger, and she could feel the orgasm building deep within her, desperate to be released. It was a battle of wills—her mind screaming for relief, her body begging for release, and Dr. Hudson's steady hand keeping it all at bay. The vibrator traced delicate patterns around her clit, while Dr. Hudson kept Anna right at that very peak of arousal, hitting that spot inside that made her toes curl and her back arch off the table.

"Remember, Anna," Dr. Hudson said, her voice a soothing balm to Anna's frayed nerves, "the purpose of this test is to assess your ability to handle extreme stress. Your job may require you to remain focused and in control, even when things get... uncomfortable."

The vibrator's intensity grew, the humming sound filling the sterile room as it danced around her clit with surgical precision. Anna's body tensed, her muscles tightening as she willed herself to hold back the climax that was threatening to crash over her. The sensation was maddening—so close, yet so far. She felt the doctor's eyes on her, scrutinizing her every twitch and moan.

"Good," Dr. Hudson murmured, her voice cool and detached. "Your body is responding beautifully. We're almost there."

With a flick of her wrist, she turned the Eroscilator up to its final setting. The sudden increase in intensity caused Anna's entire body to jolt, and she let out a muffled cry. The vibrations were intense, each touch sending shockwaves through her body that made her want to scream in pleasure and frustration. The doctor's hand remained steady, the vibrator's tip lightly grazing her clit with a precision that was almost cruel.

Anna's legs began to tremble, her eyes squeezed shut as she tried to focus on anything but the relentless pleasure. The restraints held her in place, preventing any escape from the onslaught. She felt her orgasm approaching like a freight train, every nerve in her body singing with the need to let go.

Dr. Hudson emphasizes the exam's purpose—measuring stress tolerance. The vibrator's intensity increases, pushing Anna to her limits. She fights to maintain control, her body reacting visibly with each adjustment. The doctor's focus is on the data, noting Anna's reactions with a detached professionalism. Despite her body's urgent need for release, Anna is trapped by the restraints and her desire to pass the test, creating a powerful tension between pleasure and resistance.

"Dr. Hudson, I-I can't hold on much longer," Anna panted, her voice strained.

"You're doing excellent, Anna. Remember, the goal is to push through," the doctor encouraged, her eyes never leaving Anna's face.

The vibrator's buzz grew to a crescendo, each pulse against her hypersensitive clit sending her hurtling towards the precipice of release. It was a battle of wills—Anna's determination to pass this bizarre exam and Dr. Hudson's expert manipulation of her body. With each touch of the vibrator, she could feel the orgasm coiling tighter and tighter in her belly, ready to unravel at any moment. Her breaths grew ragged, her chest heaving with the effort of holding it in.

"Remember, Anna, we need you to stay on the edge without falling over," Dr. Hudson's calm voice penetrated the haze of pleasure.

Anna nodded, her body a live wire of sensation. The final level of the Eroscilator was nothing like the previous ones. Each touch was an instant edge, a lightning bolt of pleasure that shot straight to her core. Her body was a symphony of sensation, every nerve ending screaming for release. She focused on the doctor's instructions, her breath coming in short, sharp gasps.

Her hips bucked involuntarily as the vibrator danced across her clit. The restraints held her in place, a stark contrast to the wildness she felt inside. The doctor's hand was a steady force, guiding the device with the precision of a maestro conducting an orchestra. Anna's eyes rolled back in her head, her mind racing to find something—anything—that would distract her from the relentless pleasure.

The room was alive with the sounds of the monitors beeping in time with her rapid heart rate, the graph on the screen spiking with every pulse of the vibrator. The coldness of the exam room's air conditioning did nothing to ease the heat building in her body. Each gasp and moan she made was met with a nod from Dr. Hudson, who was fully absorbed in her work, her eyes flicking between Anna's contorted expression and the data scrolling across the screens.

Nurse Donna, standing by the monitors, took meticulous notes as she observed the lines spike in a rhythmic pattern, each peak representing an edge that Anna had just ridden. She had seen many patients undergo this exam before, but there was something about the way Anna's body responded that was fascinating. Her pupils were blown wide, the pink flush of arousal spreading down her neck and across her chest. The vaginal probe showed a constant pulse of contractions, each one growing stronger, hinting at the orgasm that was desperately trying to break through the barrier of the doctor's control.

Nurse Gina, who had been quietly watching the spectacle, finally spoke up. "Dr. Hudson, I must say, Anna here is showing exceptional self-control. I've don't think I've seen someone resist for this long," she said with a hint of admiration in her voice. Dr. Hudson nodded, her eyes never leaving Anna's face as she replied, "It's true. Most subjects are incapable of this level of restraint. It's a testament to her mental strength."

The room was thick with tension as Dr. Hudson's skilled hands continued their dance, bringing Anna so close to the edge without allowing her to fall over it over and over again, almost 3 times each minute that passed by. The sound of the vibrator buzzing and Anna's stifled gasps filled the sterile space, punctuated only by the occasional beep of the heart monitor. Nurse Donna took a moment from her note-taking to glance over at Gina, who had a look of concentration etched on her features as she monitored the computer readouts.

"Nurse Donna, how many times has Anna edged so far in this final phase?" Dr. Hudson inquired, her voice calm despite the heated atmosphere. She didn't want to break her focus from Anna's face, where she could see the battle between pleasure and discipline playing out.

Donna checked her clipboard, her eyes scanning the meticulous notes she had been taking. "We're at 73, Dr. Hudson," she reported, her voice steady. "Her vaginal contractions are reaching peak levels with each attempt. It's quite impressive."

"Excellent," Dr. Hudson responded, a hint of admiration in her tone. She knew this part of the exam was the most challenging, but Anna was truly exceeding expectations. With one final, firm press, she turned off the vibrator for a second, allowing Anna's body to hover just on the precipice of release. Anna's breathing stuttered, and her eyes flew open, desperation and need etched into every feature.

"We're coming to the end of this phase, Anna," Dr. Hudson announced, her voice firm and soothing. "You've done incredibly well, and we're all very proud of you."

Anna's chest heaved with the effort of her staccato breaths, her body taut with tension. She nodded, not trusting herself to speak, her eyes squeezed shut to hold back the tide of need.

"Nurse Gina, please apply the special release monitoring pad," Dr. Hudson instructed, her voice still calm and professional. "We're moving to the climax of the exam, quite literally."

Nurse Gina opened a drawer and unwrapped a small singular white sticky pad with a small wire attached to it. She plugged the pad in with the rest and then tore off the paper on the bottom covering the adhesive. She walked over to Anna and felt around right above Anna's vagina for a moment before finding whatever it was she was looking for. She applied the pad directly onto Anna's pubic mound.

"This specialized pad just gives us even more metrics on your genital contractions. For this reason we don't apply it until we are ready to finalize the exam and bring you to climax." Dr. Hudson explained as Anna looked at them in an inquisitive manor.

Anna was elated that they had reached the end and that she would finally be allowed to go over the edge. She was sexually frustrated beyond what she ever thought was humanly possible. She had never experienced anything like these sensations before in her life. It was as if she would sell her soul just for one orgasm; to be allowed to release all this pent-up arousal she had been going through for the past 3 hours.

Dr. Hudson gets up from her stool and comes up near Anna's face to talk to her.

"Let me explain this final test to you in detail because it is an added procedure we recently developed to provide even more biofeedback." Dr. Hudson paused very briefly as she thought of the best way to explain the procedure. "What I am going to do is bring you over that edge. What I want you to do is fight it back one more time as long as possible because we are going to record how long it takes from the start of the stimulation until you are experiencing climax, that will be the first data point for this test. The second data point will be provided primarily from that new sensor pad: it will record peak intensity and frequency of your orgasmic vaginal contractions. Now with the strength of your results thus far I want to test a hypothesis I've had with you and do something a little different."

Anna listened intently to Dr. Hudson's explanations and gulped when she said she wanted to do something different; she could sense that somehow there was going to be a catch to what sounded like her finally getting what her body absolutely needed.

"What I want to test is if a female ruined orgasm is more physically intense than a regular orgasm. Let me explain what I mean because a lot of people are unfamiliar: when you are at the absolute point where your climax is completely immanent no matter what we do, I will remove all the stimulation from your genitals. You will have the orgasm with no stimulation being applied as it is happening. You are the third patient I am getting to test this theory on, and I must say the previous two found it a bit interesting." Dr. Hudson explained to Anna.

"What exactly do you mean by interesting?" Anna asked in a slightly high-pitched nervous voice.

"They were asked afterwards to describe the sensation in order to put context to our data and I believe most described it as unfulfilling, almost as if the climax had not really occurred at all. I remember one of them saying that it was somehow worse for her than not getting a release at all. Ultimately, I am curious as to what the experience will be like for you, as your resistance and level of control are stronger than theirs were based on my observations thus far."

"Great....somehow this is only going to get worse from the sounds of it." Anna thought to herself sarcastically. She could almost not believe that after all this she was going to be made into some sort of test subject guinea pig for something this sadistic seeming doctor wasn't even normally doing originally, but in her pleasant state she thought it best not to try to argue. Maybe it would be a lot more satisfying that it was being made to sound.

"For this I'm going to give you the option of which stimulation method out of the three you'd like. The sensors will function just fine with any of them and we're not really testing your responses to the different forms of stimulation anymore so the choice will be yours." Dr. Hudson said, still standing over Anna making eye contact with her as she spoke.

Anna took a deep breath, feeling a mix of relief and apprehension. She had been on the edge of climax so many times that the thought of finally reaching it was tantalizing. Despite the strange twist Dr. Hudson had mentioned, she knew what she craved. "I'd like you to do it manually, with your hand," she murmured, her voice a bit shaky. She hadn't felt a human touch in so long, and there was something more intimate and primal about it that called to her in this moment.

Dr. Hudson nodded, understanding the preference. She removed her gloves, taking a moment to replace them with a fresh pair of white latex exam gloves. "As you wish," she said, her eyes never leaving Anna's. The doctor's confidence was unwavering, yet there was a hint of curiosity in her gaze, as if she were eager to see how Anna would react to this new part of the exam.

Moving back to her stool, Dr. Hudson took a deep breath and focused her attention on Anna's glistening body. She could feel the tension in the room as the two nurses quietly prepared the monitoring equipment. Gina checked the EKG and the vaginal probe's readings, while Donna made sure the sensors were in place and the data was being recorded correctly.

"Alright, Gina, Donna, are we ready?" Dr. Hudson asked, her voice firm yet calm.

"All systems are go, doctor," Gina responded, her eyes flickering between the computer monitor and Anna's face.

Dr. Hudson nodded curtly before returning her gaze to Anna. "Remember, we're looking to ruin your orgasm. I need you to resist for as long as possible," she said, her voice a mix of professionalism and challenge.

Gently, the doctor began to massage Anna's labia with her fingers, the cold latex a stark contrast to the warmth of her skin. Anna's body quivered at the contact, her muscles tightening in anticipation of what was to come. Dr. Hudson's fingers slid over her slick folds, tracing a line from her clit to her entrance. She inserted two gloved fingers smoothly, the sensation sending a shiver down Anna's spine.

"Ah, I can see we're already quite sensitive," Dr. Hudson murmured, her voice a low, professional purr. She curled her fingers upward, feeling for the elusive g-spot. Anna's breath hitched as the doctor's touch grew more insistent, her eyes squeezed shut in an effort to maintain her composure.

When Dr. Hudson's fingers finally brushed against the roughened patch of tissue, Anna's entire body tensed. She bit her lip to hold back a gasp as her vaginal muscles clenched around the doctor's fingers. Dr. Hudson nodded to herself, a knowing smile playing on her lips as she made a mental note of the reaction.

"Am I on the correct spot Anna?" Dr. Hudson asked as if she didn't already know exactly what she was doing.

"Yes," Anna replied through gritted teeth, trying not to let her voice betray the overwhelming need that was building within her.

"Perfect." Dr. Hudson replied with her two fingers pausing for a second inside the young blonde while she pressed her thumb right next to her clitoris applying firm pressure to both locations.

"I think we are already to let the battle begin then. Nurses please watch the monitors very closely starting now. Dr. Hudson directed while looking up at them and then back to make eye contact with Anna. "Ok Anna, I'm going to stimulate now but you have to hold back until you absolutely can't anymore and when you go over the edge I'm going to take my hands off of you and we will record what happens." Dr. Hudson said in the most clinical of tones.

The doctor's fingers began rocking back and forth inside Anna's wet vagina and began to work her g-spot. She wasn't so much going in and out as much as applying alternating pressure. On the outside she was moving her thumb in light small circles right over Anna's clitoris. Anna felt a sudden spike in arousal as the doctor's skilled fingers hit the right spot. She could feel her body tensing up as she approached the precipice of an orgasm. "Not yet, not yet," she whispered to herself, gripping the sides of the exam table. The doctor's eyes never left hers, watching her pupils dilate and her breathing become more erratic.

Dr. Hudson prepares for the critical moment of the ruined orgasm experiment, focusing on precise stimulation. Anna's arousal escalates as the doctor's technique targets both her g-spot and clitoris, creating an intense sensation. The doctor's unwavering gaze and professional demeanor highlight the exam's clinical nature amidst the sexual tension.

The minutes stretched on, each second feeling like an eternity as the doctor's fingers danced along her g-spot. Anna felt the pressure building, the familiar wave of pleasure rising within her. "Almost," she gasped, her eyes flickering between the doctor's face and the ceiling. The heart monitor beeped faster, the sound echoing in the sterile room. The doctor nodded, a knowing smile playing at the corner of her lips. "Just a little more," she murmured, her voice soothing despite the torment she was inflicting.

The need to climax grew stronger, the pleasure reaching a crescendo. Anna's body tensed, her toes curling, her muscles quivering. "I can't hold it," she whispered, her eyes squeezed shut. The doctor leaned in closer, her breath hot against Anna's ear. "You're doing great. Just fight me few more seconds."

The doctor's touch grew firmer, her strokes more deliberate. Anna's breathing became erratic, her chest heaving with the effort to resist. The moment of truth was upon her—she had never been this close to the edge without release. Her body begged for it, her mind screaming for the sweet relief of orgasm. Yet she remained steadfast, her teeth gritted, her eyes clenched shut.

The monitors spiked, the lines on the screens jagging upwards as if they were trying to escape the confines of the room. The doctor's eyes flicked from Anna's contorted face to the screens, a mix of concentration and excitement in her gaze. She knew she was pushing her patient to the brink, but the science demanded it. The air grew thick with tension as the heart monitor's beep grew more insistent, a metronome keeping time with the escalating arousal.

With one telltale clench of her internal muscles Dr. Hudson knew she was a split second from forcing Anna over the edge-she could hold it back no longer. Anna was gasping and moaning almost uncontrollably.

Dr. Hudson then withdrew her fingers from Anna's vagina and with one swift motion while Anna was right on the absolute edge of release flicked her thumb right over Anna's clitoris initiated the ruined orgasm the doctor wanted so badly to study.

Anna's body rhythmically convulsed as much as it could while being held down with the straps. Her hips thrust up into the air with her pelvis a few inches off the table while her internal muscles writhed and convulsed, as if searching for something to be inside of her vagina as the doctor's skilled fingers were just a few seconds before. Anna moaned loudly in the most disappointed and shocked tones the human body can produce. The graphs on the monitors displayed the peak strength and frequency of her internal contractions to the medical team.

Dr. Hudson's expression was unreadable, a stoic mask of professionalism. "Remarkable," she murmured, scribbling notes on her clipboard. "Your body's response is quite extraordinary, Anna."

The room was silent except for the steady beep of the heart monitor and Anna's labored breaths. She lay there, legs still shaking from the intense contractions, feeling utterly exposed and violated. Yet, she knew this was a critical part of the exam she had signed up for.

"Nurse Gina, Nurse Donna, what do the readings indicate?" Dr. Hudson broke the silence, her gaze shifting from Anna to the monitors displaying the data.

Gina nodded, her eyes not leaving the screens. "Her vaginal contractions were significantly stronger during that ruined orgasm, Dr. Hudson. The data suggests that her body is indeed reacting as we hypothesized."

Donna chimed in, her voice calm and measured. "Her heart rate spiked higher than any of the previous subjects at the exact moment of the ruin, and the ultrasound shows that her cervix was fully dilated, but as expected, she didn't experience the full release."

Dr. Hudson nodded thoughtfully, then looked back at Anna with a mix of curiosity and concern. "Anna, can you tell me what that felt like for you?"

Anna's eyes remained shut as she took a deep, trembling breath. "It was... intense. Like nothing I've ever felt before. It's like I was so close, but it just slipped away." She paused, trying to find the right words. "It's like... like hitting a wall at full speed, but instead of pain, it's just frustration."

"That's excellent, Anna. Your description will help us refine our understanding of the physiological responses to ruined orgasms." Dr. Hudson's voice remained calm and professional as she began to unbuckle the restraint that had held Anna's legs apart for the past three hours. "Your endurance has been remarkable, truly. We've collected some incredible data here today."

As the doctor's gentle touch brushed against her sensitive skin, Anna couldn't help but shiver slightly. She felt exposed and vulnerable, but she knew this was all part of the process. "It's like... it's like my body was screaming for relief, but my mind was fighting it off. And when you stopped... it was like all that built-up tension just... collapsed," she managed to explain, her voice still a bit shaky from the overwhelming experience.

Dr. Hudson nodded thoughtfully, her eyes scanning over the screens displaying the data collected from the sensors. She took a moment to dictate some final notes to Nurse Donna, her voice calm and collected. "Patient shows extreme endurance with seventy-four successful edging attempts. The ruined orgasm at the end provided significant data. Vaginal contractions and heart rate spikes were notably higher than in previous subjects."

"Yes, Dr. Hudson," Nurse Donna replied, her eyes on the computer as she recorded the information. She couldn't help but admire Anna's performance. Most patients didn't last half as long.

"Now, let's remove the probe and sensors, and make sure Miss Smith is comfortable," Dr. Hudson instructed.

Gina and Donna quickly went to work, their movements efficient and practiced. Anna felt the probe slide out of her, the sudden absence of the intrusion causing another wave of involuntary contractions. She bit her lip, trying not to moan out loud.

"How are you feeling, Anna?" Dr. Hudson asked as the nurse's removed the EKG leads from her chest and wiped away the excess gel.

Anna took a deep, shaky breath, feeling the tension slowly dissipate from her body. "I-I'm okay," she murmured, her voice slightly hoarse from her silent efforts to maintain control and not wanting to reveal her now primal need for a real release that she needed to get as soon as possible.

"Excellent. Your tolerance has been quite impressive," Dr. Hudson said, her voice a mix of professionalism and genuine curiosity. "Your reactions will be vital for our research into stress management and endurance. We've gathered some very valuable data today."

Anna grinned politely as if that were supposed to be some kind of consolation for the torture that she had just been put through or relief for the frustration she was still experiencing. With the restraints finally removed and her freedom restored she sat up on the exam table waiting for any final directions.

"You can get dressed now Anna," Dr. Hudson said as she began to strip off her gloves and toss them into the medical waste bin. "Once you're dressed, I need to give you some instructions before you can leave. This is very important for the data we have collected to remain accurate."

Anna nodded, standing shakily. As she stood up and grabbed her pile of clothes, she felt the sticky residue of the oil and her own arousal on her thighs. She couldn't wait to get dressed and leave this sterile room, even though she knew she'd be taking the intense feelings of arousal with her. She slipped on her underwear, skirt and finally her shirt while the nurses went about their business still jotting down notes and reviewing their charts, her body still sensitive from the relentless stimulation.

When she was finished getting dressed Dr. Hudson walked back over from her conversation with the two nurses and met Anna's gaze.

"Since you were not able to get that ultimately satisfying release, I am quite certain you are still in a very high state of sexual arousal. There is no need to be shy about it, it is a completely natural response. We are done here for the day, but I am going to ask you to do us one last favor." Dr. Hudson began while reaching to hand Anna a business card from within her jacket pocket. "As with probably every one of our last subjects the first thing you are going to do when you get home from here is masturbate."

Anna blushed at the word and the realization that the doctor was absolutely right: there was nothing more in the world that she wanted more at that very moment than to get in her car and drive as fast possible back to her home where she could let loose on herself in privacy and finally relieve all the tension.

"What I want you to do is send me an email with some thoughts and hopefully even some details after you. I would be particularly interested in how long it takes you to reach climax, what you think about, etc. The more information you can give me the better. At this point this has nothing to do with your job application, this is more for me for a paper I am writing on our work here. I would really appreciate your help with it, although I completely understand if you don't feel comfortable doing that for me." Dr. Hudson said in a very polite tone.

Anna was now completely blushing at the thought of the entire room picturing her going home and immediately going to town on herself but figured that as fellow woman they would all have some level of empathy and understanding after an exam like that one.

She nodded and replied while smiling bashfully "I think I can do that for you, I don't mind."

"Excellent, I appreciate that very much. Nurse Gina will walk you back to the front desk where you can pick up your completion form for the employer and go on your way." Dr. Hudson replied.

Nurse Gina took Anna by the hand, leading her through the labyrinth of corridors. Anna felt the cool breeze of the air conditioning on her still-flushed skin, the friction of her clothes against her sensitive areas adding to her discomfort. She couldn't help but feel the throbbing between her legs with every step she took. Despite the ordeal, she walked with a sense of pride. She had done something most would find unbearable, and she had done it for a chance at a dream job.

When they reached the reception area, Nurse Gina gave some form to the receptionist at the desk, another young brunette in scrubs, who then handed her a neatly folded document. "This is your official completion form. Make sure your employer sees it. They'll understand the importance of what you've just been through and why you might need a bit of recovery time." She winked, and Anna felt a warmth in her chest, appreciating the nurse's kindness amidst the clinical setting.

With the form in hand, Anna walked out of the facility into the bright, midday sun. She felt a strange mix of emotions: relief that it was over, but also a persistent, unfulfilled yearning that seemed to pulse with each beat of her heart. The exam had left her on edge, her body craving the release that had been denied for hours.

As she made her way to her car, she couldn't help but reflect on the intense experience she had just endured. The way Dr. Hudson's skilled hands had brought her to the precipice of ecstasy, only to pull her back at the very last second, had been a dance of the most exquisite torture. Yet, the doctor's calm demeanor and the professionalism of the nurses had kept the atmosphere from becoming anything other than a clinical test of her limits.

As she got into her car, her genitals still throbbing and aching for an actual release. She thought about her need to get home as soon as possible to relieve herself. She looked down at the clock and with it reading 4:45pm she knew the traffic she was about to deal with would delay her from getting back to her apartment as fast as she needed. She let out a huge sigh and shook her head in disbelief and frustration as she put the vehicle in gear to pull out of the parking lot and head home.
