Ginney's thoughts came back to the present as she rounded the corner with her house in site at the end of the block. Yet another thought occurred to her, "Was nurse Alcott treating her less and less as a student patient and more like a friend?" She seemed more gentle these last few weeks. Perhaps this was more than just a job.

The real truth was actually close to Ginney's expectations. Nurse Alcott had in fact taken more than a casual interest in Ginney. Ms Alcott was however more interested in the extent that she and Mrs. Elliott could draw Ginney into the exotic sexual life that they had been developing. Nurse Alcott was waiting with Ginney's stepmother as Ginney walked into the living room. Ginney kissed her mother and said hello to the nurse.

She was instructed to accompany them to the large studio her mother had built several years ago as an exercise room. Four months ago all the unused exercise equipment had been removed. Only the black padded horse in the corner remained and the room was now filled with the normal items that would be found in a doctor's examination room. Two large strategically placed ceiling lamps illuminated the generous OB couch and its stirrups. Stainless steel trays held towels and surgical gloves. Other trays held numerous sizes of catheters for rectal and urinary insertions. Glass syringes of various types were available as were tubes of surgical lubricant patiently waiting for their application on some delicate female part.

Being at home allowed sessions without any inconvenient interruptions of classes. She wouldn't have to make excuses to her classmates for unusual trips to the nurses office, etc. etc. After a while Ginney was even convinced. She realized the simple logic of the arrangement and became used to coming home to spend an evening in this room to be given an enema or some other medical procedure that her stepmother had cooked up.

The nurse decided it was time to begin the proceedings and suggested to Ginney that she go into the adjoining dressing room bathroom combination and remove her school clothes and return in the examination gown that they had left for her. It only took a few moments to remove her skirt, sweater, bra and panties. Standing naked in the room, she took the white satin garment they had left for her and proceeded to pull it over her head . The simple one piece shift had buttons half way down and clung to her breasts like eager hands. Her nipples stood out prominently through the thin fabric which made the already alluring look of the shirt somewhat obscene. The garment was tight around her waist and flared over her generous hips falling just above her pussy. Looking at herself in the mirror she could see that the open v-top gave no protection to her voluptuous breasts from curious eyes as the buttons only came halfway up to her mid chest. It certainly left her ass and pussy free for a com plete examination. This garment was obviously designed to be seductive and sexy rather than clinical. In fact, her nipples were so sensitive to the silk that they stood erect as her large glands pressed the turgid buds against the clinging material.

Ginney turned once more to the mirror to survey her sexy costume, then quickly returned to the larger room and her impatient stepmother and school nurse.

She was greeted by compliments from nurse Alcott and her stepmother which made her blush as they ogled her partially naked figure.

"All right now Ginney, up on the table, on your back, legs in the stirrups, and we'll begin" said Susan Alcott.

Ginney settled herself on her back with her feet high up and apart, cushioned by the fur lined stirrups. This position provided unrestricted access to her pale pink teenage vagina as well as displaying all the charms offered by her delightful backside. The tight curve of her ass now exposed the deep crease in the center of the plentiful mounds which highlighted a brown and crinkled anus winking playfully in the open air.

Nurse Alcott moved Ginney slightly lower on the table so that her legs were now almost perpendicular to her torso. This served to widen the gap at the juncture of her legs and vividly placed on display the sensitive organs that would soon be manipulated to her tormentors satisfaction.

"Did you follow my instructions from this afternoon?" the nurse asked. "Liquids only and not to relieve yourself until you arrived here at home."

"Yes, Nurse " Ginney replied, "but I really have to go badly and that tampon inside me is huge."

"You know that Nurse Alcott is helping us to maintain our cleanliness program here at home." offered Mrs. Elliott. "She agrees with me that the school facilities could be the cause of some of the contagious diseases that students contract unknowingly. According to your most recent urine test you may have acquired a minor infection in your bladder which may have been caused by the dirty toilet seats at school. Nurse Alcott is going to help me treat that infection now so that we can resolve the problem. Susan thinks she can arrest the infection from spreading if we complete tonight's catheterization properly."

Nurse Alcott pulled a tray containing three thick red catheter tubes closer to the table. Each of the tubes had clips on the slightly fluted ends and each tube was of a different diameter. The tubes ranged in sizes from #22 to #26 which, when translated into a standard measurement meant 1/4 to 3/8 of an inch in diameter.

With rubber gloves donned, she bent over and opened Ginney's vagina by pulling back the folds until she exposed the entrance to her urethra. Ginney was accustomed to this type of examination by now as each week the nurse would scrutinize her clit and urethra while making various comments about her cleanliness and bodily health.

Ginney would often close her eyes during these ministrations and let the tingling sensations growing from her clit build as the probing became more intense.

The purpose of her prior weekly manipulations was to open the urethra to its maximum dilation for catheterization. Ginney had no idea that nurse Alcott had planned this penetration many months ago even though she knew that her peehole had been stretched far beyond the normal size for girls her age.

And now, with the Novocain working nicely in Ginney's rear, the nurse knew that Ginney would only feel a mild discomfort when the largest catheter slipped up the short canal and penetrated her bladder.

The nurse began by rubbing a small quantity KY jelly on the open cunt, working the gel around the inner areas of her slit. She continued the massage until she could easily tell that the young girl's waiting pussy had relaxed sufficiently to allow the catheter's insertion.

Nurse Alcott selected the largest diameter tube and, after lubricating it she prepared to begin the urethra's penetration. The nurse parted the sensitive opening with the two fingers of her left hand and pressed the tube into the small opening. She pushed harder as the tunnel refused to open to its uninvited visitor. The skin compressed under the increased pressure but the canal remained closed to the large invader. More pressure and the hole completely disappeared until, at last, the orifice opened its tiny mouth and let the giant snake slide in. Slowly the tube stretched the small canal to make its way further towards the girl's full bladder.

At first, Ginney experienced a slight painful sensation but with the effect of the Novocain tampon still in her rectum, the pain melted quickly away as the large catheter continued into her body. About 3 inches had been inserted when nurse Alcott placed two fingers inside Ginney's vagina pressing upward to feel the tube inside the short urethra. She massaged the upper wall of the vagina noting that the tube sat comfortably in the small passage. The insertion slowly continued as the nurse pressed the catheter towards the young patient's bladder accompanied by a few throaty cries and some "ohhhhsss, and ahhh's." The urge to pee was overwhelming.

Ginney felt multiple sensations as the tube broke into her bladder. At first, a sweet stinging sensation then a series of hot flashes combined with the increased pressure of having to relieve oneself. Her bladder began releasing its contents. The liquid rushed down the tube unrestricted seeking an exit.

Fortunately, the clamp on the end of the tube was effective in blocking the flow of hot urine and the urge to expel continued unresolved.

Nurse Alcott shuttled the tube in and out in short slow movements. At first, she would partially withdraw the tube for a brief moment, then press it back into the vessel. Then withdraw slowly then press forward even slower. The seesawing motion felt just like a long thin dildo fucking her cunt.

The tube would timidly leave, then cleverly force its way back into the sensitive organ. Each time the catheter moved in either direction a shiver would travel around her body.

The urge to expel the pent up liquid was becoming overwhelming however as nurse Alcott watched Ginney struggle with her impossible assignment.

"Oh, please, I have to go now. Please let me go !!"

Susan watched as Ginney tried to relax her peristalsis instinct but the pressure in her bladder was too much.

"Ah, please, now, now, I have to go !!"

Susan could see that Ginney was having great difficulty holding off from an inevitable accident so she finally allowed the flow to exit the tube into a waiting glass pitcher. It seemed as though the liquid would never stop as Ginney grunted with the relief granted from the immediate deflation of her bladder.

The two conspirators watched as the urine rapidly filled the empty beaker to the 16 ounce mark. At last the flow completely stopped and nurse Susan clamped the tube to let her patient rest for a few moments before continuing the more serious part of the cleansing.

Ginney was tired and hardly felt the nurse take the rectal forceps and remove the cotton suppository inserted earlier in the day . After squeezing a copious quantity of lubricating gel on her patients rectal area nurse Alcott let Ginney rest.
