Please step in, Simone said to Anita. As she climbed into the tub, Birgit saw that the seats were also fitted with latex bonds. She had not noticed this at first glance because of their white color.

Anita sat down in the tub. The supports for the legs were attached at a 90° angle so that the legs were spread wide. In addition, the entire seat was tilted back about 45° to allow the patient a relaxed posture. The seating area was cut out in the shape of an omega so that the tubes protruding out of the girl's orifices dangled unhindered. Also, supports for the arms were molded into the tub on which Anita's arms were now shackled. Her legs were fixed also and finally a wider straps was attached above her breasts and pulled tight. The tubes were now screwed into connectors under the seat. Birgit's horniness crept up because she would be soon strapped down into the tub in exactly the same way as Anita; she felt the constant bondage to be pretty hot.

Certainly, the plug and the long colon tube contributed to her excitement; which Birgit could feel inside her bowels at every movement. After Anita was strapped down tight it was Birgit's turn. The two sisters grinned at each other when they were lying there face to face, belted down in such a lewd manner. Simone then told them how their colonic will proceed.

Once the tub is filled with water and the Jacuzzi function is activated, the colonic irrigation begins. The water will slowly flow deep into their bowels, then would drain through the stopper so that their entire large intestine will be cleansed, Simone explained to Birgit. Initially, very small amounts of water would be pumped in until the colon is cleaned of solid residues, then the flow rate will be increased slowly. In between, there will be breaks, so that the water can drain out properly. The pressure of the water will be very closely monitored and carefully controlled. Simone pointed with her hand in the direction of the switch boxes. You will feel the flush as very pleasant and relaxing, she promised addressing Birgit.

Anita's colonic irrigation will be a little different, Simone then said. At the beginning Anita will be thoroughly rinsed too. After this initial cleansing, Anita's bowels will be filled again and the water pressure in her intestine will slowly be increased until, after a while, the water will be drained again. Thus Anita will be prepared for her enema treatments later on. Because of this Anita got a different stopper in which a valve for closing the drain is built in. Aha, Birgit thought, that's why Anita's sphincter was gasketed. In addition, Anita's bladder will be cleansed, too.

The treatment will last 45 minutes. Have a nice time, Simone said and left the room.

The warm water wrapped the sisters up to the neck and the Jacuzzi feature was activated. At the thought of the now beginning cleansing, Birgit felt her lust in her pussy. She had hardly reclined her head on the padded headrest before she felt the water flowing into her gut. She closed her eyes and moaned softly and full of pleasure. Anita, who had been watching Birgit attentively, smiled to herself knowingly.

Despite the heat Birgit got goose bumps down her spine. Man, this is beautiful! she thought. Anal is fantastic! Never before in her young life Birgit was excited so deeply.

The colonic irrigation processed exactly as Simone had said. The water flowed slowly into Birgit and when she began to feel full, the inflow stopped and the water ran out again. After a few minutes, as Birgit's intestine was cleansed from coarse residues, the flow in her became more constant and finally as much water drained as was pumped into her. Birgit enjoyed this infinite flow inside her young body and relaxed more and more.

Her sister seemed to enjoy her cleaning too. Anita leaned her head back in the seat and smiled quietly. After about 20 minutes Anita began to breathe harder and Birgit opened her eyes. Her sister was breathing deeply now with closed eyes and a strained facial expression. Surely the pressure augmentation has been started, Birgit thought while watching her sister. Anita opened her mouth and deliberately breathed deeply. Watching Anita's facial expressions, Birgit could clearly determine that her strain was increasing. Then she shut her mouth again, but her breathing was still hard. After some time Anita relaxed. Aha, now the valve has opened and she is draining, Birgit thought.

She would have liked to see the assistant seated behind her and watch the displays, but she could not turn her head around far enough. After some time this game started again, Anita breathed harder, she grimaced and after a holding time she was drained again.

Little by little, sighs mingled with her with her breaths. Her enema pressure will certainly increase more and more, Birgit thought. Towards the end of the colonic, her sister's behavior had already become quite strong. Anita silted her eyes tightly, intermittently breathed fast in and out, short moans were heard and she moved her head slowly back and forth. The strain that Anita was subjected to was clearly visible now. After the 45 minutes both girls were drained and the water was pumped out of the tub.

Birgit was a little embarrassed as she smiled at Anita. Birgit would like to have asked Anita what she had just been put through, but she held herself off. Tonight, they would have enough time to talk about it, Birgit thought.

Assistant Simone appeared and unstrapped Birgit, while the other assistant took care about Anita.

Well, how did you like it asked Simone and Birgit said how stunning and erotic the treatment had been. She would never had thought that enemas could give so much pleasure. Anita smiled happily to herself as she heard her sister's answer.

Birgit should come with her, Simone said, as her a massage is scheduled, while Anita would be prepared for her enema training. Simone instructed her colleague: go ahead and strap Anita down onto the kneeling-rack, I will be right there, she finished. Aha, thought Birgit, Anita will probably get high enemas like she recently had downstairs in the clinic.

Simone led Birgit into a room with a leather upholstered massage couch on which lay a large towel. Simone told her to lay down on it, face down, and wait a moment. Another colleague will appear shortly and will spoil her a little. Simone pulled the colon tube of Birgit's gut and then left the room.

Not bad, Birgit thought, this is really a luxury program for me.

The assistant appeared, of course in the same latex outfit as the others. She welcomed Birgit and took off her latex gloves before she lubricated her hands with warm massage oil and trickled some of the oil onto Birgits back. Birgit relaxed noticeably under the practiced hands. After about fifteen minutes, the assistant told Birgit to turn around and she massaged her front. First, feet and legs, then the shoulders, arms and gently her belly. Gradually, the massage strokes got more soft and caressing and finally Birgit felt her hands on her small, firm breasts.

Birgit gladly let her continue and, due to the sensations that spread throughout her sexy body, she closed her eyes. Finally, the assistant was massaging the pubic area and Birgit willingly spread her legs apart. Then she heard the well-known hum of a vibrator and felt it on her labia immediately. She moaned out loudly as the assistant touched her clit. Slowly an orgasm was developing in her and as the assistant pressed the vibrator firmly on her clit, Birgit reared up and screamed out her feelings of pleasure.

The assistant asked Birgit if she had liked the massage. Birgit enthusiastically thanked her. You should remain lying a few minutes and relax, said the assistant. Simone will come in and pick you up. Still full of enjoyment, Birgit lounged on the couch.

She wondered if she would be led back to her sister. Birgit was very eager to find out what would be done to Anita. Surely she did not receive any relaxing massage and had most likely been flushed out on the kneeling-rack. Simone came in and told Birgit could now join her sister and watch her enema treatments.

She was led into a treatment room. The sight of her sister there made her gulp.

Chapter 6: Enema Training

Anita was strapped to a kneeling-rack that had very little similarity with the one that was used downstairs.

At first view, Birgit could see the protruding and widespread ass of her sister. A thick enema tube with a large inflated balloon was fixed in her anus. Ah, she has a Bardex in her, Birgit thought once she had overcome the initial surprise. The other assistant stood near to Anita and watched the flow of the enema which drained from a large, now almost emptied bag, into Anita's receptive bowels. Birgit could hear deep breaths from Anita like in the hot-tub before. Simone led Birgit to a comfortable leather upholstered chair on the opposite wall. From there she could see her sister from behind and also see what the two assistants were doing.

For a start, Birgit examined the kneeling-rack her sister was strapped onto. Looks really high-tech, Birgit thought. This kneeling-rack was not a simple frame like downstairs but rather was placed on the floor on top of a thick column, which could be moved up and down. The support on which Anita was strapped consisted of several parts. Her legs were tied to supports that could be adjusted separately for lower leg and thigh. The base plates were made of stainless steel covered by latex padding. Anita's legs were buckled firmly with countless latex bands. The legs were bent at the knees and moved forward towards the body. In addition, the legs were spread wide so that the assistants had free access to Anita's asshole. Her upper body was lying on a plate that had cutouts for the breasts and Birgit could see Anita's stiff nipples peeking out below. Her chest was strapped with two wide latex belt onto the plate. Her arms were attached to supports corresponding to those of the legs.

In essence, she was lying on the rack like a jockey.

Several tight latex straps reliably prevented any movement. She lay with her forehead on an curved bracket that emerged from the chest plate and Anita looked down to the floor. Of course her head was also strapped with latex straps to this bracket so that Anita could not look over to Birgit. The whole of the chair, together with the defenseless Anita, was finally tilted forward by a ball joint at the upper end of the column.

Anita's belly hung down freely and Birgit's eyes widened when she saw that it already had a decent swelling from all the water sloshing in her. Finally, the enema was completely in her sister and the supply tube was removed, but the assistant left the Bardex tube in Anita's anus and said, you will keep these 4 liters in for 10 minutes before we go on. Anita was as quite as a mouse and just kept on breathing deeply.

4 liters? My goodness, thought Birgit, she really can tolerate quite a bit.

In the meantime the assistants cleaned the enema bag and various substances were poured into waiting pitchers, which were then mixed with large amounts of water. After about ten minutes Birgit thought that her sister would be unbuckled to empty herself. Instead, Simone pressed a button on the kneeling-rack and it moved, with Anita, to a vertical position; while her position on it remained unchanged. Now her bottom was the lowest part of the body. Simone put a big basin below Anita. Then she let the air out of the Bardex-balloon and pulled it out of her patient. Anita emptied herself with a mighty splash into the basin below. Again and again waves of water drained out of her ass until finally four liters of crystal clear liquid had flowed into the basin. Anita was tilted forward again and Simone rolled the container away. Meanwhile, her colleague had already prepared the next enema and rolled the IV-stand with the freshly filled four-liter bag next to Anita.

Anita's butt was cleaned and then lubricated again. This time a short thick enema nozzle was introduced into Anita and Simone explained that she will now let the water run into Anita's colon very fast so that it expands slightly and stretches. Simone's colleague pushed the bar of the stand with the bulging enema bag as far up as possible and then released the clamp on the hose. Anita moaned briefly as the water shot in her gut. Among sound of her soft sighs, the bag emptied quickly. Anita had her eyes closed and was breathing heavily with an open mouth as Birgit looked anxiously toward her. Simone left the enema in her for a short time before she moved Anita back to the vertical position and released the nozzle.

While Anita spasmodically emptied herself the assistants already prepared the next run. They mixed a white powder in a pitcher of water and stirred; the water immediately became white and fairly viscous.

The next enema will be administered very slowly into you, Simone explained to Anita. We have thickened the water, so you will feel it heavily inside your abdomen. This time you will have to take four and a half liters in your sweet ass, Simone said with a slightly sadistic tone in her voice. She took a syringe with a lubricant in her hand and squirted some into Anita's rectum.

Then she reintroduced the long, thick double balloon Bardex tube and connected it with the hose coming from the enema bag, which was hung much lower this time. The enema was started and this time Anita did not make a sound. Very slowly, the thick liquid drained into her. When the bag was about half empty Anita closed her eyes and breathed a little louder. Gradually her stress increase. and she sighed softly as her belly filled up more and began to inflate. Finally, she had taken the whole portion and the inlet tube was removed. This will remain now 15 minutes in your bowels, so you'll be stretched inside.

Birgit was a little queasy. They put Anita through the mill quite nicely. She had to recall what Anita and Dr. Lay had said to her last night and this morning. Birgit could hardly believe that her sister underwent these procedures voluntarily. But obviously Anita let the assistants do their work without any resistance to it. Birgit also noticed that some of Anita's moans sounded really lustful. Birgit started to see her sister in a different light and took a pride in her. Excitedly, she watched the treatment.

Once Anita had dropped the milky liquid out in several waves, she got two 3-liter-enemas to clean her gut out again. In fact, the first of the enemas was still mostly white.

Then Simone said to Anita that it will get a little bit harder now. Although the amount of fluid she will have to take now will be only two liters, this enema contains substances that would stimulate her intestinal tract and will developed a strong peristalsis. To prevent the enema from splashing out, I will lock your sphincter with the inflatable stopper. Simone inserted a short rectal tube that was attached to a stopper similar to that used in the Jacuzzi. As before Anita took the big plug without any fuss. The sealing tubes were inflated and Simone connected the intake tube to the stopper. Have fun, Simone said and started the enema.

The water drained quickly into Anita. Simone removed the intake tube and then sealed the connection in the stopper. Anita was still calm, she lay with her eyes closed on the frame, and was breathing quietly.

That's 20 minutes of retention, Simone said to Anita; who sighed deeply.

Birgit was extremely nervous. What would happen now? What will her sister have to suffer now? Will the cramps be severe?

Anita began to breathe heavily. First, sighs were heard and she screw up her eyes. With her open wide mouth, she moaned softly.

After a few more minutes, Anita's reactions became more violent as she writhed in her bonds.

Birgit gazed at her sister with open mouth. Anita's moans were now quite loud and Birgit was shocked at how Anita's abdomen contracted and relaxed under the bowel movements . She must be experiencing severe cramps! Birgit could not believe what was happening before her eyes. She shifted nervously back and forth in her chair. Slowly she got an inkling of what masochism meant.

Without ceasing, her sister moaned her suffering out loudly with wide open eyes and pulled at her bonds. The cramps came in waves over her and Anita breathed only intermittently. Birgit looked sorrowfully at her sister's apparently insane suffering.

After another endless 20 minutes had elapsed, Anita was allowed to drain; all the while still suffering from the severe cramps. The water literally exploded out of her. Even when she was back in the knee-elbow position, she was still breathing hard. Small beads of sweat clung to her forehead, which were dabbed away by the assistant.

Anita got some rest before the next enema was administered.

Now you will get a large herbal enema so that your bowels will relax again and will bulge out, Simone said to Anita as she filled another bag. Then she hung it to the IV-stand, while her colleague inserted a long colon tube into Anita and inflated the balloons. You'll like this one, Simone said to Anita and started the flow. She massaged Anita's abdominal wall and Anita really seemed to enjoy this, Birgit noticed.

As the herbal water was filled halfway into Anita, Simone took a vibrator and massaged her dripping wet pussy. It only took seconds before Anita had a strong orgasm - right in front of her sister - and writhed in her bonds like she did during her cramps.

Birgit was astounded about her sister's change from severe suffering to excessive lust and wondered if Anita had also had feelings of pleasure during her severe enema. Birgit made a mental note to ask her about her feelings that evening.

Maybe in her sister's mind, pleasure and pain lay very close together and Anita was able to mix these feelings up. In any case, Birgit needed to do some in-depth research about masochism.

After Anita's orgasmic waves subsided, she was told by Simone that the enema now will remain in her for half an hour. Turning to Birgit she said that it is almost one o'clock now and that a little snack is prepared for her.

She led the still very confused Birgit to a room that was apparently otherwise provided for the staff. Some purses lay on shelves and on a small kitchenette some food was prepared. Birgit was told she should help herself. Simone had to go back to Anita and prepare her for the treatments scheduled in the afternoon. Shortly thereafter, the assistant that had performed the massage on Birgit in the morning came inside and also got herself some food.

Anita will probably get nothing to eat, Birgit said to herself while thinking of her sister; who was still lying on the kneeling chair with a filled belly. Birgit could hardly believe what she just had seen.

The assistant smiled and engaged her in a harmless conversation while they ate.The conversation distracted Birgit from her bewilderment.

Chapter 7: Elucidation for Birgit

After about three quarters of an hour, assistant Simone came back to pick up Birgit. Your sister is relaxing a little bit now from her treatments, she said to her. Maybe you also want a bit of variety, she asked with a mischievous smile. By now, Birgit had the desire for her own treatment. Watching her sister during her training had not only confused her but also made her pretty excited right from the beginning.

So she said, yes I would like that. Simone said that since she had liked her bladder cleansings so much, would she now like to give her one. So this news has already come up here in the upper floor, Birgit thought and turned red with embarrassment. Okay, she said to Simone and followed her into a treatment room where a gyno-chair was set up.

Truly luxurious treatments here at the clinic, Birgit thought. She was delighted with the courtesies that were chosen for her.
