Julie hurried along the sidewalk, the heels of her shoes clicking busily. It was nearly one o'clock, and this was one appointment she didn't want to miss. She pushed impatiently past a frail-looking old woman, nearly bowling her over, but didn't pause to apologize. Her long dark hair billowed behind her as she sped along; she looked, and was, a perfect specimen of healthy, beautiful youth and arrogance. She had places to go and things to do, and people could just stay the hell out of her way.

Ah, here it was. The Holmewood Clinic for the Study of Human Sexuality, the sign read. Julie didn't really give a damn what the place's title was, or indeed what they studied; all she needed to know was that they were willing to pay three hundred bucks to experiment on her tight little bod. And that three hundred was going to come in handy in preparing for this weekend's skiing trip with Mark. She smiled a little as she pushed open the door of the office building, imagining her tall, handsome boyfriend's expression when she got him back to their room and unveiled that sweet little chemise she intended to buy tonight. She loved to see the lust suffusing his face when she wore even the most marginally sexy clothes in front of him, loved to tease him with the sight of her body. Maybe this she'd actually let him fuck her this weekend; it all depended on how prettily he begged. She glanced down at her watch and noticed that it was now one-oh-four.

The receptionist looked up with a coolly professional smile as Julie approached the desk. "Good afternoon, Miss Prater. The doctor is ready for you." There was a hint of admonishment in her tone, as though the doctor's time were much too important for him to be kept waiting even a few minutes, and Julie felt an angry flush spread over her cheeks. She opened her mouth to tell this snotty bitch where to go, but something about the sterile atmosphere of this place stopped her. She had been surprised last week, during her preliminary examination, to find the clinic no different in appearance from any other doctor's office. She had expected something a little more ...comforting, but instead there was the same mildly oppressive feeling that she remembered from her rare visits to her family physician.

The door connecting the waiting area with the actual laboratory opened now, and a tall, blonde woman in nurse's whites smiled warmly at Julie. "Come on in, honey, we're all ready for you." Julie was a little taken aback by the endearment, but shrugged it off as just one of those things nurses say; or perhaps the woman just remembered her from her last visit, and felt like they were old friends. Who knew? Returning the woman's smile with a small one of her own, she obediently followed her into the inner recesses of the clinic. The antiseptic smell that seemed to permeate all medical settings filled her nostrils, and she felt a vague uneasiness rising within her, along with a mildly embarrassing surge of arousal. The nurse opened the door to an examination room and motioned her inside.

Julie blinked in surprise at the sight of a very large and ominous-looking piece of machinery which dominated one whole side of the room. She stopped dead in the doorway, staring, until the nurse gently nudged her forward. "Just sit down in one of the chairs for now, dear. The doctor will be here shortly." Well, that was to be expected, she thought absently, waiting for him even though she had been a bit late for her appointment. She took a seat in one of the black vinyl-covered chairs and gazed in awe at the machine while the nurse slipped her chart into the plastic holder on the door. The woman paused for a moment in the doorway, and Julie looked at her inquiringly. "Hon, in this office you have a choice as to whether or not you want to wear a gown while we perform the study. I know you wore it last time, but since we're going to be examining almost every area of your body today ...?" She trailed off uncertainly, and Julie shook her head. "Don't worry about it. I'm fine." Her response brought an approving smile from the nurse. "All right, sweetie. The doctor'll be with you in a moment, then."

Julie relaxed into her chair, returning her gaze to the strange machine. What was it for, anyway? There was a sort of seat at the front of it, but it was shaped in the form of a large H with outward-curving sides, so that the thighs of the person sitting upon it would be the only thing really supported. Julie drew some small comfort from the fact that the seat seemed to be well-padded; she had no doubt that today would see her set upon that device. After all, she was here to have weird experiments performed on her, wasn't she? And when she left she'd be three hundred dollars richer; let them have their fun. Maybe the doctor would even get his rocks off from exploring her sweet pink pussy. Who cares, she told herself. I'm in this for the money.

She was entertaining thoughts of what the strange machine might be capable of doing when the door to the exam room opened, startling her. She jumped guiltily and turned to face the doctor, feeling a slight warmth come to her cheeks. She was a little surprised by his youthful appearance; during her first visit, she'd not met him, her only contact having been with the nurse. He smiled kindly at her, his brown eyes warm. "Well hello there, Julie. How are you feeling today?"

She smiled back at him flirtatiously, giving him the full force of her white teeth against carefully tanned skin. "Horny. Isn't that what you wanted to know?" His eyes widened for a moment before he chuckled, and Julie felt a tingle of triumph at having gotten through his doctor's armor for a moment. The hospital aura of this place had broken her stride for a little while, but she was damned if she was going to act like the typical lab-rat. She was a woman, and a damn attractive one; no way was she going to be relegated to "just another patient." Not by a doctor as cute as this one.

His eyes flickered over her, and he frowned slightly. "Didn't the nurse tell you to remove your clothes? We can't perform the study with them on." She shrugged, aware that her body shifted seductively under her clothing as she did so. "No, she didn't say anything. Hold on, I'll take them off." Looking directly into his eyes, she reached for the bottom of her sweater, expecting him to stop her and offer to step outside. But to her surprise, he simply stood and watched as she pulled the garment up and over her head, revealing perfect, youthful breasts unfettered by a bra. She smiled as his eyes dipped downward to view her flesh, and she rose, now determined to give him the full show. Kicking off her shoes unobtrusively, she moved her hands and her gaze to the buttons of her jeans, pretending to fumble with them in order to prolong her little striptease. She stole a glance at his face and was a bit offended at the lack of expression there; with a small sniff she opened the fly of her jeans, sliding them and her underpants down her long legs and off.

As he watched the young woman attempting to seduce him, Dr. Edmunds kept his face carefully blank, although he snorted inwardly. When his kid brother had begun telling him about the high-box bitch in his Calculus class who only got a passing grade by wearing micro-miniskirts and crossing her legs in class, his mind had flashed instantly to similar girls he had known, girls who had snubbed him throughout his high-school and college days, before his skin had finally cleared up and the idea of dating a future doctor had become quite attractive in female minds. He had never really gotten over the humiliations he had suffered at the hands of various beauty queens, could still hear their laughter as they discussed his utter audacity in asking one or another of them for a date. He could well sympathize with Jacob when he spoke of having less than a snowball's chance in hell of ever touching this one ...but then Jacob, the lucky little shit, had an older brother who could help him in his cause. He glanced over the girl's shoulder at the hidden videocamera and smiled a little, knowing that his little brother was enjoying the sight of her flesh unknowingly displayed for him.

"All right then," he began crisply. "What we're going to do today, Julie, is to gather data concerning the female body's responses to various kinds of stimulation. I know that sounds a little frightening," he smiled disarmingly, "but all it really means is that we're going to try different ways of bringing you sexual pleasure, while measuring the contractions of your vaginal muscles as you approach orgasm. Does that sound about like what you expected?"

Julie was still a bit sulky at his non-response to her nudity, but she suppressed any outward sign of it, telling herself that he was simply keeping his professional mask on in order to keep from embarrassing her. "But I thought that's what the nurse did last time, Doc. She had this thing up inside me, and she said that it was measuring the contractions when I ...you know." She blushed prettily and quite purposely, glancing up at him from beneath her lashes, and he barely restrained himself from laughing aloud. This little slut was really trying her best to get his interest, he thought. Little did she know that she already had it, and not for the sake of research. The thought brought a too-wide smile to his face, and he moderated it quickly, lest she become suspicious. "Well, that was what the probe was doing, Julie, but that was just a preliminary measurement, to let us know what signals your body sends when your climax approaches. You see, we're not really interested in the orgasm itself in this study. We're looking more for ways to predict the moment, so to speak. So little is known about the subtle variations in sexual response among women; we're looking for similarities among all of you, so that we poor males might have a better chance of pleasing our partners." He grinned wolfishly at her, and was not surprised to see the pleased triumph in her eyes before she dropped her gaze. Go ahead and think that I'm flirting with you, dear. We'll have plenty of time for you to realize that you're not the one running this show. "So you see, we needed that data in order to know when to stop the stimulation today, so that you don't reach orgasm before we're ready." That brought a slight look of worry to her face, and he turned away quickly to keep from laughing.

"Now what I need you to do, Julie, is just step right over here to the examining table and lie down, on your back." When he felt that he could control his facial expression sufficiently, he turned to face the young girl who climbed onto the padded leather table, the white paper barrier crackling beneath her weight. "Feet in the stirrups and scoot down to the end of the table, please." She looked annoyed. "Doctor, I had an internal and a Pap smear done last time I was here. Do we have to go through this again?" She was thinking of the chemise she wanted; the lingerie boutique closed at six, and she didn't want to be here forever.

"No, we're not going to do a full internal, Julie. I just need to examine you for a moment, make sure everything's up to par and ready for the study. It won't take long." She sighed and placed her bare feet in the stirrups, flinching a bit at the coldness of the metal. He turned to a nearby cabinet and donned a pair of latex gloves, making sure to give them the final snap loudly enough so that the videocamera would pick up the sound. Hope you're enjoying it, Jacob. He hooked the nearby examining stool with his foot, pulling it closer to the table, and sat facing the young woman. Glancing over to the tray of instruments beside the table, he smiled in satisfaction; he did love his work, especially when the patient was as young and lovely as this one. He picked up the tube of KY jelly and squeezed a bit onto his gloved right forefinger, feeling a tingle of anticipation at the thought of touching the sweet flesh before him. Not bothering to rub the lubricant onto his finger to warm it, he rolled his stool forward a bit and casually opened the pouting lips of her sex with the fingers of his left hand, relishing her soft gasp. As he slowly inserted his finger into her vagina, he noted the flushed and glistening appearance of her entire sex; she was clean-shaven, allowing him an unobstructed view of her body. Her swollen labia and slightly protruding clitoris gave mute testimony to her arousal, and he noticed a slight twitching of the latter as he probed her soft warmth. Keeping a watchful eye on her reactions, he began slowly exploring her sex, curling his finger upward slightly as he slid along the upper wall of her vagina until he encountered a small patch of spongy, slightly rough-feeling tissue.

The change in her body was immediate and dramatic as he began pressing rhythmically against that sweet spot, massaging it gently in a beckoning gesture. She sucked in a deep breath, her thigh muscles tensing slightly, and her clitoris gave a violent jerk, then flushed a deep red as the hot blood of sexual arousal flooded its tissue. A soft groan escaped her lips, and he smiled gleefully for a moment before withdrawing the finger rather suddenly, ignoring her quiet gasp. "I'm going to do a rectal examination now, Julie. You're going to feel my finger against your bottom, and I need you to bear down slightly against it, all right?" He squeezed a bit more KY onto the gloved digit, waiting for her protest.

He was not disappointed. "Doc, I don't want anything up there! Come on now ..." He rose and looked down at her sternly, noting the hectic flush of color in her cheeks from mingled embarrassment and arousal. "Julie, this is all part of the preparation for the study. If you don't want to go through with things, just tell me, and you can put your clothes on and go home." Without the money was the unspoken addendum, and Julie gritted her teeth. "All right, all right ...go on." She'd just close her eyes and think of other things ...like this weekend, for instance.

He laughed silently, pleased by her obvious reluctance, and reached to spread the stirrups a bit wider, until the small twin globes of her buttocks were opened sufficiently to allow access to her anus. The small puckered rosebud was a dark brownish-pink in color, quite pretty, and judging from her resistance to its exploration, he would bet on its being untouched. Lovely ... "Now just relax, Julie ...and bear down when you feel my finger." He reclaimed his seat. Smiling a little, he reached up slowly and brushed his finger across her hole. Seeing her shiver a bit at the unexpectedly pleasurable sensation, he then began pressing against the tight ring of muscle. She pushed obediently, and the sphincter opened a bit, allowing his fingertip entry. He pressed a bit harder, feeling the resistance slowly fading, until his latex-clad finger finally slid most of the way inside her body. She whimpered softly, and he felt his cock stir in response, the slow tingle giving him cause to be grateful for the concealing length of lab coats. He was entranced with the tight warmth surrounding his finger, and a sudden idea made him bite his lip to hold back a wicked smile. "Uh-oh."

She opened her eyes in alarm. "Uh-oh?" He reveled in the slight fear in her voice; how he loved wielding the power of a doctor, the unwilling awe felt for those who know the human body better than most, and the idea of using that power to subject this arrogant young beauty to the humiliation she deserved sent a jolt of electricity through his groin that was unlike anything else. He slowly slid his finger from her body and stripped off his gloves, standing. "I'm afraid you're a bit impacted down here, dear, and that could interfere with the accuracy of the data we want to gather. We're going to have to clean you out."

She blinked. "What do you mean, 'clean me out?' Like a laxative or something?" A horrifying suspicion was growing in her mind, and she prayed that he wasn't saying what she feared he was. His soft laughter at her question brought a miserable flush to her cheeks, and she knew that her fears were correct. "No, my dear. A laxative would take far too long to produce the necessary results. I'm afraid you're going to have to have an enema." He saw her jump slightly at the mention of the word, and his cock lurched in answer; this was going to be more fun than he had thought. He expected a violent protest from his young patient, but surprisingly, she merely nodded, a dark blush staining her cheeks. Hmmmm ...

"All right." She wouldn't have admitted it under threat of death, but the fear produced by the idea of this handsome young man giving her an enema was mildly arousing. She excused her submission to the procedure by telling herself that it was necessary in order to complete the experiments and collect her money, but at her very core of consciousness she sensed the importance of the three hundred dollars slowly fading in her mind, replaced by a tingling anticipation of pleasure. At the bidding of the young doctor, she pulled her feet from the table's stirrups and rested them upon the very end of the table, relaxing for now.

Dr. Edmunds excused himself for a moment, leaving Julie to collect herself and think of things to come. He instructed the nurse to enter the exam room and prepare the enema equipment for use, along with administering a small dose of medication to their young patient; the statuesque blonde smiled widely and hurried to obey. The doctor himself strode down the hall in the opposite direction. Coming to a small room approximately the size of a walk-in closet, he opened the door and stepped inside, smiling as the young man seated at the television console turned to him. "Man, Tom! This is fucking unbelievable ...you really gonna give her an enema?" The doctor smiled fondly at his younger brother. "You better believe it, kiddo ...plus a few other things that I think you'll like." He raised a hand as Jacob opened his mouth excitedly. "No, I'm not going to tell you. Suffice to say that you're going to see your little Julie in some situations you never even dreamed of." He grinned. "Gotta go ...just wanted to check and make sure the video was coming through okay." Before he even turned toward the door, Jacob's gaze was returned to the screen. Horny little bastard ...just like his big brother. Tom chuckled to himself as he exited the room.

Meanwhile, in the examining room, Nurse Bennett was helping Julie to a sitting position, a glass of water held in her right hand, and a small plastic cup containing a blue tablet sitting on the nearby tray. "Now dear, we're going to administer a very mild sedative, just to make sure that you don't have any excess tension that might interfere with your body's reactions. Don't worry, it's nothing that will make you sleepy or anything of the sort ...it will simply relax you slightly. Now drink up, that's a good girl." Julie was mildly annoyed at the condescending note in the nurse's voice, but she obediently swallowed the offered medication. I need something to get me ready for this, she thought. In truth, the sticky wetness between her thighs could not be completely attributed to the KY jelly ...but that was something that she was not prepared to admit.

The door opened, and Dr. Edmunds stepped in, his gaze automatically going to the enema bag suspended by an IV stand next to the examining table. He smiled in approval, then turned to Nurse Bennett. "You've given her the sedative?" Only the nurse caught the slight hesitation before the last word, and she fought back a giggle at the naughty glint in his eye. "Yes, Doctor. She should feel the effects in just a few moments." Indeed she should, thought the nurse. The powerful diuretic she had just administered to Julie was bound to induce a rather quick and uncomfortable need to urinate ...at just about the time when the enema would begin its work as well. The doctor smiled at her, and she saw her own excitement mirrored in his gaze. "Good. Now Julie," he said, turning to the young patient, "one of the requirements of the tests we're going to be running today is that they continue uninterrupted ...that means no breaks of any kind. The tests will last only about three hours, so I'm sure you'll be able to go that long without going to the bathroom, don't you agree?" Without giving her a chance to answer, he nodded to the nurse, who smiled quickly and departed. "After your enema has been administered, Nurse Bennett will insert a very small catheter tube into your urethra. That's going to drain your bladder more fully than you would be able to on your own, which will also help with the accuracy of the data we want. It may be a bit uncomfortable at first, but it won't really hurt, and it will really help in our study. So just relax and bear with us, okay?" He smiled, and the girl sitting on the table flushed a bit and smiled back. She was feeling a bit uncomfortable with these preliminary procedures, but the tingling arousal between her thighs was undeniable, and she murmured assent to his plan in a quiet voice very much unlike her normal tones.

He beamed. "Good ...now, all you have to do is just lie back and bring your knees up to your chest ...I'm going to give you a standard two-quart enema, and you'll have to hold the solution inside for about ten minutes. If you start to cramp while the solution is going in, let me know, and I'll stop the flow for a few seconds until it passes." He paused. "Oh, and breathe deeply ...sometimes that helps. Ready?" She nodded, blushing ...what else could she do? She lay back slowly, assuming the position he had dictated.

The doctor savored the sight of the dark-haired beauty behaving with such sweet submission. What a change from the haughty little thing that had first stepped into his office! But this was just the beginning; before this visit ended, she would know the limits of her body's capacity for arousal ...along with the delicious addition of pain to her pleasure. Oh, this was going to be wonderful. Making sure to stay slightly to one side, to allow Jacob a full view of the lithe young body upon the table, he donned another pair of gloves and lifted the enema nozzle for inspection. He knew that Nurse Bennett would have sterilized the equipment both after its last use and before this one, and he noted with satisfaction that she had thoughtfully lubricated the nozzle as well. That left him with only the delightful task of readying the girl's anus for the slender intruder. Smiling comfortingly down at her, he applied yet another dollop of KY jelly to his finger and reached down to her body once more. Julie gasped softly as he began massaging the slippery gel into her, and he felt his erection throbbing harder than ever. She had her eyes fixed on the ceiling, giving him full opportunity to savor her expression as his finger invaded her anus. She bit her lip softly, her brow furrowing as she tried to relax her muscles, and the mild suffering apparent upon her angelic face was nearly his undoing. He withdrew his finger and busied himself with the enema nozzle, willing the tightness in his loins to subside. God, he would have to be careful with this one. One finger up her ass and she almost had him coming in his pants. He was grateful when Nurse Bennett reappeared with the catheter equipment; any distraction was welcome.

"Now, Julie, I need you to relax as much as you can." His voice didn't tremble, thank God. Bracing himself against the surge of excitement that he knew would come, he took the vaguely penis-shaped enema nozzle in his hand and pressed it against her tightness. "Push down, dear." She gasped sharply as the instrument began its entry into her body, and he exchanged a long look with the nurse, feeling his heart pound. Pressing more firmly as her body's resistance faded, he soon had the nozzle seated deeply within Julie's rectum. "All right ...I'm going to start the water now, Julie ...just relax and take a few deep breaths." Her face slightly flushed, the girl nodded understanding, and Dr. Edmunds released the clamp upon the rubber tube. Almost immediately Julie gasped in shock as the warm liquid began flowing into her bowels. Closing his eyes for a moment, the doctor held the nozzle firmly, keeping it completely still inside her. God, this was delicious, he thought. He could do anything he wanted to this girl, repay her a thousand times over for the sins she had committed along with those other little snobs ...and he had a feeling she would merely lie there and endure it. She whimpered slightly as the bag continued to drain its contents into her body; about one-half quart had now entered her. "Oh, please ...stop for a minute!" She gasped and grimaced as a cramp struck her, and he reached for the clamp almost reluctantly. "Breathe, Julie ...that's my girl ..." Without being told, Nurse Bennett stepped forward to begin massaging the girl's belly, helping the cramps to ease. She looked up at the doctor as she worked, her eyes bright with lust, and he knew that she was reveling in the taut feel of the flesh beneath her hands. When Julie's breathing returned to normal and she seemed more relaxed, Dr. Edmunds again reached to open the clamp, allowing more of the warm fluid to invade her body. She groaned softly with the increased pressure, and he realized that the diuretic was beginning its work as well. The girl's entire belly must seem full to bursting, with the pressure of her uterus, engorged with blood from her arousal, only adding to the ache. He somewhat regretted not telling Jacob of the full plans for Julie; the younger man would have enjoyed knowing that the demands of her bladder would continue to increase throughout the afternoon. But a guy's gotta have some secrets, he thought, and grinned to himself.

A thought struck him suddenly, and he reached to click the clamp shut, ceasing the flow of water into the girl's body. Approximately one-half of the bag remained, and Nurse Bennett looked at him inquiringly. He winked at her quickly. "Well, that's that, Julie. Now we'll just need you to hold that for a few minutes." Looking over at the nurse, he silently mouthed the word twenty, knowing that the girl would soon be so caught up in the sensations flooding her body that she would have no idea how much time had passed; all she would know would be the urge to release the liquid churning in her bowels. The volume of the enema was smaller than originally planned, but since Julie wasn't really constipated, one quart of liquid would certainly get the job done. With a smaller volume of solution used, the doctor knew that the usual cramps associated with the process would be much less, resulting in the ability to hold the liquid for a longer period of time ...and unless he was mistaken, a slow buildup of arousal in the receptive young girl. Nurse Bennett smiled and nodded. "You've never had an enema before, have you, Julie?" the woman asked. "N-no ..." came the soft answer, and both doctor and nurse felt a surge of excitement at the sound of slight confusion in the girl's voice. The pressure in her belly was powerful, bordering on pain, but with the combination of her earlier passion and the now-sharp need to relieve her bladder, she felt a strange and utterly uncontrollable throbbing of her clitoris, as though she could come without any encouragement at all ...and she didn't want to be aroused by this! She blushed, feeling that the two people watching her could easily spot her excitement ...which they could.

"Well since you've never done this before, sweetheart, we're going to have to give you a little something to help you retain the liquid until it's time to go." The nurse's kindly voice was somehow deeper now, but Julie was oblivious to this as she felt the pressure in her belly turning to slight cramps. She moaned softly, not seeing the identical expressions of lust the sound produced upon the faces of the two people above her. Vaguely she wondered what the nurse meant, but she nodded assent, not really caring anymore what they did. She felt somewhat lightheaded, her entire body flooded with warmth from the water filling her; even the pain of the small cramps was muted, as though it were happening to someone else.

Nurse Bennett quickly stepped past the doctor, to the instrument tray beside the table. Selecting a shiny black object from the array of equipment there, she expertly lubricated it with the KY jelly, nodding to the doctor when she finished. "Now Julie, what we're going to do is remove the nozzle now so that you can move about a bit more freely. In order to help you retain the water for the necessary time, we're going to insert a plug into your bottom ...are you ready?" A softly moaned affirmative answer sounded, and Dr. Edmunds stepped back to allow the nurse room to work.

"Julie, as soon as this leaves your anus, I need you to tense your muscles so that the solution stays in there, all right? I'm going to put a towel underneath you just in case ...there. It's okay if a little leaks out, but we really need for most of it to stay inside you for the whole time. Okay ...easing the nozzle out ...all right ...and ...now!" The nozzle slipped free and Julie groaned loudly as the need to release the pressure inside her grew almost unbearable. Some of the solution dripped onto the towel beneath her, but she quickly clenched her muscles tight, trapping the rest inside. The nurse smiled approvingly as she laid the nozzle into a tray attached to the IV stand, then immediately placed the anal plug against the girl's body and began to push. Julie was of course unable to push against the intruder to allow it freer access to her body, and the feeling of invasion was much stronger as the lubricated latex plug was forced into her anus. She moaned in pain as the object reached its widest point, then narrowed sharply so that her muscles clamped tightly around it, trapping it inside. Trembling, she lay there limp, a slight sheen of sweat coating her body. Nurse Bennett smiled and patted Julie's thigh. "Very good, my dear. How are you feeling?" The girl moaned quietly in answer, and the nurse chuckled. "A bit full, eh? Well, it won't be much longer ...but now it's time for your catheterization. Here, just put your feet back up into the stirrups." She helped the girl to position her body for the procedure, lifting her feet and placing them in the cold metal stirrups, then spreading them wider than ever. Julie groaned softly as the new position seemed to increase the already-immense pressure in her lower belly, and the nurse pressed her thighs together unobtrusively beneath the concealing fabric of her white skirt, feeling the throbbing of her own sex. Donning a pair of sterile gloves, she reached forward and casually parted the girl's labia, revealing the sweet pink opening below her fully erect clitoris. Julie gasped sharply at the woman's touch, her body jerking slightly upon the table, and Nurse Bennett cautioned herself to go slowly, lest the arousal and excited pressure within the girl's body build to a climax ...after all, that would ruin the "tests" scheduled for today. She carefully wiped the girl's open sex with a cotton pad soaked in antiseptic, smiling as Julie cried out softly at the touch of the cold liquid. Not to worry, my sweet, I'm going to warm you right back up again. Discarding the antiseptic wipe, the nurse reached for the tube of KY jelly and squeezed a generous amount onto her hand. Replacing the tube in the tray, she rubbed her fingers together, simultaneously lubricating all four digits of her right hand and warming the slippery gel. She then returned her left hand to its duty of spreading apart Julie's labia and began applying the lubricant to the girl's mound, massaging gently.

"Oh God ..." Julie whimpered before she could stop herself. The feel of the nurse's hand upon her sex, combined with all the other sensations assaulting her, was bringing her perilously close to an explosive orgasm, and she was mortified to be this aroused by another woman's touch! No one of her own gender had ever touched her in this way, and she was astonished at her own reaction to the gentle probing; her clitoris felt swollen to twice its normal size, her vagina seeming to melt into a pool of liquid heat. She felt a strange trembling within her lower belly as Nurse Bennett began massaging and lubricating the area of her urethra, the movements sending shocks of pleasure upward to her clit ...oh God, she didn't want to come from this! But it was going to happen ...just a few more passes of those deliciously tantalizing fingertips and she was going to explode.

Nurse Bennett smiled as she listened to the girl's quiet sounds of reluctant pleasure, purposely prodding the engorged clitoris upon each stroke of the urethral opening. An expert at her job, she watched the tiny organ carefully, and when it suddenly began to draw back into its hood in preparation for the contracting waves of orgasm, she abruptly stopped all stimulation, leaving her patient gasping for breath, torn between relief and frustration. Seeming oblivious to the girl's plight, she calmly turned and selected a narrow tube from the sterile tray. She considered for a moment simply allowing the girl's urine to collect in a bedpan after catheterization, but rejected that idea. The thought of watching Julie's blush as she saw a clear bag filled with her own waste was just too delightful to resist. Having worked in the medical field for several years, the nurse was inured to most disgusting sights ...but her patients were not, and their embarrassed reactions to the functions of their own bodies was a never-ending source of amusement to her. So a bag it would be ...

Julie shuddered slightly as the pleasure of the probing faded, to be replaced by an ache that rivaled the cramping of her belly in its discomfort. She didn't want to admit how badly she had wanted-needed-Nurse Bennett to bring her to orgasm. She bit her lip against a groan of desire, feeling her clit pulse and throb as though searching around for more stimulation. She felt the woman's hand return to her sex and nearly cried aloud, feeling the fingers spreading her lips wide once more, exposing the pearly pink flesh. Then the lubricated catheter tube began moving against her body, seeking an entrance, and her eyes widened at the new sensation. The nurse quickly found the tiny opening to Julie's urethra and began pressing the tube against it ...slowly, so slowly, the tiny invader forced its way into the girl's resisting flesh, drawing a long groan from her lips. Still the tube moved forward, searching for the gateway to her achingly distended bladder.

Julie gritted her teeth as, after an agonizingly slow progress, the catheter finally entered her bladder. She gasped at the sharp burning sensation, then her eyes widened as urine began to flow unrestricted down the tube into the collection bag ...this was unlike anything she had ever felt before, this rapid, effortless draining of her body. She groaned with pleasure at the relief, feeling as though she could even stand the pressure of the enema now, just as long as that terrible stretching of her bladder was taken away. She felt the throbbing of her clitoris subside somewhat and sighed. At least now I don't have to worry about coming my brains out while a nurse massages me.

When the contents of Julie's bladder had emptied fully into the collection bag, Nurse Bennett pretended to examine the connection of the carrier tube to the bag's neck, slyly closing a small clamp at the end of the tube that invaded her young patient. Soon enough, the medication the girl had been given would induce another intense need to urinate; now the hot liquid would merely travel down the catheter tube before encountering the barrier of the clamp. The nurse knew from long experience that the demands of Julie's bladder would simultaneously distract her from and intensify the sensations of sexual pleasure, and she looked forward with great anticipation to witnessing the girl's agony. "We're just going to leave the catheter in place for the duration of the tests, Julie. Sometimes ...well," she gave the girl a conspiratorial smile, "the intensity of the feelings induced here have a tendency to cause 'accidents' in some patients, but with the tube in place, that won't be a problem." Of course it wouldn't, the nurse mused as Julie nodded weakly. She knew that the closed tube leading from her patient's urethral canal was every bit as effective a barricade as was the anal plug that mercilessly held in her enema. And speaking of which ...she checked her watch. Yes, it was time. "All right dear, it's been long enough for the enema to do its work. You can visit the bathroom now." The girl sighed with relief before attempting to sit upright. Nurse Bennett quickly stepped forward to help, supporting Julie's collection bag with one hand and her back with the other, but the discomfort of moving with a full quart of warm liquid within her bowels was still great, and the young girl moaned softly. With the nurse's help, Julie slowly removed her feet from the stirrups and climbed down from the table. She was acutely aware of the plug holding in her enema, along with the strange tube that led from her private areas to the bag the nurse was holding. As she moved across the room, the liquid within her body seemed to slosh around a bit, and she looked down, gaping in disbelief as she saw the slight distension of her stomach. She went pale at the thought of how much fluid she had taken, and as the nurse led her to the door, she wondered if she were going to be able to hold it in for the trip, even with the aid of the anal plug. As the nurse reached for the doorknob, Julie felt a moment of panic. "Wait! I don't have any clothes on!" No way was she going to walk through this clinic stark naked, especially not with a tube up inside her and a plug up her ass!

Nurse Bennett looked mildly annoyed for a moment, but she stepped to the drawer set into the side of the exam table and drew out a ridiculously thin paper gown. "You're the only patient here, Julie, so there's no one to see you but us ...but if this will make you feel better, go ahead and put it on." She handed the gown to the young girl, who slipped it over her nudity gratefully, leaving the split in front and holding it together like a robe. "Now, let's get you to the bathroom, young lady." The nurse opened the door and motioned Julie out into the hall.

The thirty seconds or so that it took for them to reach the bathroom were the longest of Julie's life. Finally, her bare feet met the tile and she headed straight for the toilet. "Thanks, I'll hold that." She reached for the collection bag that Nurse Bennett still held in her hand, and the older woman's apparent reluctance to surrender the bag and leave the room shocked her. Was she planning on being present while Julie voided her enema? If so, she'd better think again! "I can take things from here, nurse, thank you." The woman eyed her for a long moment, then a small smile appeared at the corners of her lips and she nodded. "All right, dear. Press that call button on the wall if you need anything ...and be careful removing that plug." She handed Julie the collection bag and stepped out, closing the door behind her.

Inside the tiny video control room, Jacob hit the button that his brother had said would give him a view of the bathroom's happenings. Sure enough, the screen flickered for a moment, then filled with the scene of the lovely young woman sitting upon the toilet. He thought of her scoffing reaction when he'd finally gotten up the balls to ask her out last year, and a snide smile spread across his face. Maybe he'd never get to actually touch that pussy, but he sure was getting a good view of it! The image of Julie's horror if she knew that he was witnessing the humiliating procedures being performed on her brought a pleasant ache to his groin, and he began rubbing the length of his erection through his pants as he watched her. She reached behind herself to remove the plug, and he smiled in anticipation.
