Measured Desire [F25/M30s/M30s/M30s/M50s] [Medical Exam] [Humiliation] [Doctor] [Gyno] [Group Sex]

The exam room's sterile fluorescence washed over Lily, bleaching her skin in its harsh glow as she lay on the padded, paper-covered table, legs caught in the cold grip of its metal stirrups. The lamps above her hummed faintly, their brightness biting at her eyes, while the sharp scent of antiseptic in the air stung her nose with each breath. None of that discomfort, however, compared to the raw vulnerability she felt having her bare pussy exposed to the scrutiny of Dr. Marcus and his three residents.

While the white coat-clad men clustered around the end of the table, Lily gripped its edges, her cheeks burning. Medical settings always unsettled her, but her yearly gynecological visits were the worst. Now, having reached the age of twenty-five, the socially acceptable age to bear children, the visits felt increasingly invasive. Her friends had called the exams "routine," but now, lying here with all eyes on her, their reassurances were beginning to ring hollow.

Standing just slightly behind the residents, Dr. Marcus cleared his throat. The grey streaks in his dark hair shone where they caught the bright light, and his calm gaze briefly met with Lily's nervous one.

"Alright, Miss Webster," he began, his tone cool and professional. "Today we will be conducting a compatibility assessment to determine your optimal penile dimensions for maximal physiological response." He spoke in a completely clinical manner, almost casual, like he was discussing collecting a blood sample and not the mechanics of her pleasure.

"If you are ready, we will begin with the first part of the exam," he informed her, a trace of warmth creeping into his words. "Do you have any questions before we continue?"

Lily shook her head, her pulse quickening as the unease threading through her thoughts grew stronger. She had to bite her lip to keep herself together. "No questions, Doctor."

The sharp scratch of Dr. Marcus's pen cut through the hush of the room before he spoke again. "You may feel some pressure or mild discomfort at various points during the exam. Please inform us if you experience any pain. We will begin by taking some baseline vaginal measurements. Dr. Kingston, please proceed with the comprehensive external and internal vulvar measurement."

He nodded to one of the residents who strode forward, his strong jawline set with a smug smile. Towering over the others, Dr. Kingston's broad shoulders strained his coat, his biceps bulging as he plucked a sterile calliper and digital probe from the instrument table.

"Let's get started," he said, voice brimming with confidence as he moved to stand between Lily's legs. His gloved fingers spread her pussy wide, exposing her clitoris and inner folds to the cold air. Lily tensed, flinching as he pinched and pulled on her skin with the calliper.

"Labia minora width is 1.2 centimetres; thickness is 0.4 centimetres; length is 4 centimetres. Initial canal opening is 2.4 centimetres," Dr. Kingston reported. Without warning, he set aside the calliper and grazed her clitoris with the digital probe, sending a jolt through her that made her jerk her hips. A smirk flashed briefly on his face, just long enough for Lily to catch, before his professional mask returned. "Clitoral hood sensitivity is heightened, visible engorgement and reflex response noted."

That smirk made Lilly wish the ground below her would open up and swallow her whole.

Each time the resident reported his findings, Dr. Marcus nodded encouragingly and jotted more notes on his clipboard. The other residents watched silently as Dr. Kingston finished up the measurements, their eyes fixed on Lily as she was all but dissected before them.

"Proceed with manual palpation," Dr. Marcus instructed.

Dr. Kingston reached for the bottle of lube on the equipment table and smeared a generous dollop onto his meaty fingers. Then he slid two of them into her pussy, probing her slick walls with slow, methodical pressure. Lily jumped when he entered her; the cold plastic of his gloves felt so foreign and strange inside of her. She found herself unable to stop a gasp from escaping as his fingers explored deeper, lingering on her G-spot. In a desperate attempt to hold in a moan, she bit into her lip again, the humiliation brought on by this invasive exam rising as rapidly as the pleasure it sparked.

"Vaginal muscle tone is firm with strong elastic recoil," Dr. Kingston relayed, the slightest trace of amusement creeping into his voice. "Anterior wall shows pronounced sensitivity. Baseline lubrication is moderate and increasing. Let's move on to the arousal threshold assessment. Dr. Greene, the stimulation device, please."

One of the waiting residents, a tall and lanky man, fidgeted as he started the motor on the medical-grade vibrator he held. He gingerly handed it to Dr. Kingston, then used the same hand to push his wire-rimmed glasses back up his nose. Mortification swelled in Lily as she watched the exchange, her mind racing at the thought of how her pussy would respond under the doctors' watchful eyes.

With careful precision, Dr. Kingston pressed the tip of the vibrator to her clitoris, cycling through intensities. The vibrations sent a surge of pleasure through her, her pussy clenching involuntarily around the doctor's fingers, and a soft moan slipping past her lips despite her efforts to stay silent. Dr. Kingston raised an eyebrow, and Lily's cheeks stung with shame.

"Clitoral response is immediate, vaginal contractions intermittent in correspondence with the device's intensity. Arousal indicators are pronounced with lubrication increasing rapidly."

Dr. Marcus nodded his approval. "Very good. Complete the baseline assessment with internal measurements."

"Prepare for the internal exam," Dr. Kingston instructed his colleagues. He set the vibrator aside and removed his fingers, giving Lily a moment to let out a shaky breath of relief. Assisted by the others, he prepared a large, metal speculum and a thin, wire sensor probe. Lily squeezed her eyes shut when she saw it, intimidated by the speculum's size.

"You may feel some mild discomfort during this part of the exam, Miss Webster. Please take a deep breath." Dr. Kingston urged as he aligned the speculum tip with her opening. "Very good. And out."

Lily did as she was told, and as she exhaled, Dr. Kingston pushed the speculum inside of her. Once inserted, he wasted no time cranking it open, its wide expansion stretching her uncomfortably.

"Any pain?"

"No," she answered, voice strained with fresh embarrassment. She kept her eyes closed, turning her face into her shoulder.

Next, she felt the sensor probe slide along her walls, its gentle vibrations making her clench, especially when it brushed her cervix. She did her best to mask a shiver of pleasure with a cough.

"Vaginal depth is 16.4 centimetres. Internal temperature 37 degrees Celsius." Lily heard the click of the doctor's pen light and felt him shift the speculum for a better view. "The vaginal walls appear highly elastic with significant lubrication already accumulating. Make a note of the frothy, white lubrication pooling around the cervix. I'll collect a sample for lab testing."

He inserted another tool, using it to gently scrape her cervix. Lily whimpered and squirmed, the self-assured, detached way Dr. Kingston spoke about her making her feel like a lab animal.

"Please try to remain still, Miss Webster," Dr. Kingston chided, taking another sample with a swab before handing it off to a colleague. "Collection complete. Baseline measurements concluded."

All business, he closed the speculum and removed it. Lily opened her eyes just in time to see Dr. Kingston wipe it clean. She hoped they didn't notice how her pussy throbbed in its absence or how embarrassingly wet she was.

"The first part of the exam is complete, Miss Webster," Dr. Marcus told her. "The results all appear to be within normal range. We will now move on to phase one of the size compatibility test. Dr. Green, please prepare for penile insertion."

Dr. Greene fumbled as he untied his scrubs, glancing at Dr. Marcus before taking Dr. Kingston's place in front of the table. He pulled them down with trembling hands, just enough to reveal his modest, erect cock.

Lily swallowed hard at the sight of it. When her friends had talked about their own experiences, she had imagined the doctors using dildos, not their own penises! Still, when she confessed her nerves to them, her friends had assured her the exam wasn't so bad.. Some of them had even admitted to enjoying it. She wanted to believe them. Taking a slow, deep breath, Lily tried to calm her hammering heart by reminding herself that the doctors were professionals. They knew what they were doing.

To finish his preparations, Dr. Greene timidly accepted the lube offered to him by Dr. Kingston. He squirted some in his hand before carefully lathering it over his cock. Then he took a slim, electric sensor band and pushed it midway down his shaft.

"Preparation is… um… complete," he announced. "Let me know if you feel any pain, Miss Webster."

Lily couldn't even speak. Dr. Green's gentleness eased her tension slightly, but not the humiliation of being watched by the others. She only nodded, eyes wide with disbelief.

"Please try to keep your legs open wide," he advised, slowly easing his cock into her. Lily gasped, her pussy clenching instinctively, and a warm flush of pleasure spreading from deep in her core. His cautious movement felt less invasive than Dr. Kingston's bold touches, but the embarrassment remained.

"Initial observations?" Dr. Marcus urged, his pen poised.

Tentatively, Dr. Greene thrust deeper, his cock sliding easily through her wet heat. "Moderately tight initial fit with smooth accommodation," he mumbled. He avoided Lily's gaze just as intently as she dodged his.

Across the room, Dr. Kingston watched one of the large, beeping screens, noting aloud what he saw. "Sensors indicate slight vaginal contractions and a vaginal pressure of 10mmHg. How is the patient's lubrication?"

"It's uh… Ample, easily facilitating penetration." Dr. Greene swiped a gloved finger over Lily's clit, causing her hips to buck. "Clitoral engorgement persists, sensitivity unchanged. Vaginal walls show an appropriate elastic response with no evident discomfort to the patient."

Dr. Marcus peered over Lily's thigh, taking a long look at where his resident's cock disappeared into her. "Is insertion fully completed?"

"Yes."

"Has contact been made with the patient's cervix?"

"No," Dr. Greene answered softly with a grimace.

"Very good. Withdraw and move on to phase two. Dr. O'Hare, please ready yourself."

Dr. Greene pulled out, stepping back to clumsily re-fasten his scrubs and leaving Lily glistening under the harsh lights. Next, Dr. O'Hare stepped forward. His white coat was pristine, and his blond hair neatly coiffed. Not a single strand out of place as he paused to tilt his head and study her with intense curiosity. He prepared himself the same as his colleague had, first lubing his visibly thicker and longer erection, then sliding the sensor onto his shaft before pressing his girth against Lily's slick folds.

Lily's eyes widened, the delicious burn of his stretch drawing a stifled moan. She tried not to think about the way her walls gripped the resident's cock tightly or the wet sounds each of his movements made.

"There is significant stretch and strong muscular response," Dr. O'Hare reported, thrusting into Lily with steady control.

"The sensors are registering high vaginal contractions and pressure in response to this stimulation." Dr. Kingston added.

Lily couldn't stop herself from moaning as Dr. O'Hare's cock kissed her cervix. Nor could she ignore the shudder that racked through her when he reached down to expose the hood of her clitoris. "Lubrication is copious, indicating high arousal. Cervical contact is being made infrequently. Dr. Greene, please take a clitoral measurement."

Dr. Greene approached hesitantly, pressing the probe to her clit. Instantly, she jumped, her breath hitching into a high-pitched whine. "Clitoral pulse is elevated," he reported quietly.

"Withdraw and continue onto phase three." Dr. Marcus instructed, still absorbed with charting the residents' findings.

Dr. O'Hare pulled out. Lily felt her juices trickle down her ass cheeks when he did. She didn't want to think about the stain she was leaving on the paper sheet, or that all the doctors would be able to see it.

Now it was Dr. Kingston's turn. He fitted the sensor around his massive cock, his size nearly double that of the first resident. "Preparing to attempt insertion," he said, applying a generous amount of lube before aligning himself with Lily's entrance. She whimpered, her pussy straining painfully despite her slickness.

"It hurts," she groaned. Dr. Kingston's head had barely broken past her entrance.

"Deep breaths, Miss Webster. Try to relax," Dr. Marcus soothed.

Dr. Kingston stroked her clit with bold, quick strokes, pulling back a little before pushing in again. He made slight progress, but Lily still cried out in pain. His smirk faded. He tried a final time to thrust forward, his thumb circling faster, but it made no difference. Lily was too tight to fit his meaty girth. He stilled his movements and shook his head. "Excessive resistance and obvious discomfort. This size is beyond the patient's capacity. Withdrawing."

Dr. Marcus noted it calmly, then gave the next instruction. "Return to the previous size for ideal compatibility confirmation."

Dr. O'Hare approached again, the sensor refitted around his cock, and slid back into Lily with precise ease. Her pussy welcomed his return, moulding perfectly to him, the stretch now purely pleasurable. She moaned freely, her hips lifting from the table to meet him.

Once Dr. O'Hare fell into a rhythm of deep hitting, steady thrusts, Dr. Kingston also returned to the table. His cock still bulged visibly in his scrubs as he leaned over Lily's side and applied the vibrator back into place. Guided by the screen behind him, he moved the vibrator around in search of the most sensitive spot, making Lily's toes curl in ecstasy.

"Clitoral pulsations frequent, vaginal contractions visible on screen. Vaginal pressure reads as elevated, 8mmHg."

Dr. O'Hare now plunged deeper and harder, grunting with exertion. "Vaginal walls highly responsive. Lubrication optimal."

"Indeed, the vaginal pulse is strong; pre-orgasmic state confirmed." Lily couldn't see Dr. Marcus with her eyes squeezed closed, but his voice washed over her with a new wave of shame. She fought against her climax, her legs shaking with the effort as louder and louder wet squelches filled the room. She was afraid of losing control of herself in front of the doctors.

"Continue stimulation to confirm comparability via climax." Dr. Marcus ordered.

Dr. O'Hare picked up the pace, a sheen of sweat breaking across his forehead. At the same time, Dr. Kingston turned up the intensity of the vibrator while Dr. Green came to stand on the other side of the table and gingerly palpated Lily's abdomen.

"The patient is tightening significantly," Dr. O'Hare noted through his panted breaths.

Dr. Kingston upped the intensity of the vibrator again. "Clitoral sensitivity is at a maximum."

"Faint uterine contractions detected, aligning with vaginal response. Orgasm is imminent," Dr. Greene added.

Lily's core tightened painfully, her shame battling her need for release. Dr. Kingston was the first to notice her struggle. "It appears the patient is struggling to relax."

"Miss Webster," Dr. Marcus said in the steady, authoritative voice of a doctor needing his patient to listen. "Please try to relax, the assessment is nearly finished."

Lily thrashed, her moans uncontrollable as her pussy clenched, but she kept herself from going over the edge.

"Applying additional stimulation," Dr. O'Hare announced, his voice sounding distant. Lily couldn't see what he was doing—she couldn't see anything, she was so blinded by the pleasure—so, when she felt his gloved finger tease the outside of her anus, the surprise quickly overwhelmed her resistance.

She came with a mortified cry tearing from her throat. Her pussy convulsed wildly, soaking Dr. O'Hare in her juices, who continued thrusting through her climax. He took her to the very end of it before growing still and reporting his observations.

"Sustained vaginal contractions. Climax has been achieved. It appears the patient's vaginal capacity aligns perfectly with a medium size, maximizing stimulation and orgasmic intensity."

He withdrew from Lily, as did the others, leaving her trembling and spent.

Dr. Marcus nodded some more, scribbling again on his clipboard. "Yes, these results do seem fairly conclusive. Further analysis of the findings will likely confirm our initial suspicions. Document thoroughly and prepare for follow-up."

The residents all stepped back from the table, Dr. Kingston adjusting his scrubs with a confident flex, Dr. Green fumbling with his and Dr. O'Hare pausing with his cock still in hand to study one of the monitors. They went to work with mechanical efficiency, as if Lily's shuddering climax was nothing more than another boring data point. Like she wasn't still just lying there, pussy drooling and pulsing, the aftershocks still making her quiver.

With a snap, Dr. Marcus closed his chart. "Well done, gentlemen. The patient's compatibility assessment is complete."

Then he glanced at Lily, his tone professional and firm. "Miss Webster, we will schedule a follow-up appointment to review the final results prior to your annual anal stimulation exam. Do you have any additional concerns you'd like to address today?"

Lily shook her head. Being reminded of it, she wasn't sure if she was looking forward to the next exam or not after this experience. "No, doctor. Thank you."

"A nurse will be in shortly with some tissues and wipes to help you clean up. We'll see you in a couple of weeks. Take care of yourself, Miss Webster. I suggest sticking to a regular masturbation routine to help maintain a healthy sexual response."

With that last piece of advice, Dr. Marcus and his residents exited the room, leaving Lily to grapple with her lingering mortification and the throbbing aftermath of her exam.
