Chiara felt the warm soapy water flowing into her ass. She had never had such a strange feeling in her entire life. The balloon in her anus stretched her rectum in an unpleasant way - at the same time, a warm feeling spread through her bowels. She now lay tensely on the examination table, her bottom stretched out into the room and her glowing head towards the wall. Moritz was sitting on the couch and was still looking in awe at his best friend's butt, from which a long tube was sticking out, continuously pumping the enema fluid into the girl. "Cleansing the bowel is very important before the rectal examination. The gynaecologist can only examine your rectum really thoroughly if you are clean at the back. And the doctor doesn't want to get his fingers dirty in your butt. Don't worry, it may be unfamiliar and a little uncomfortable, but every girl has to go through it. The soap broth will first loosen the faeces in your bowel, then you will be allowed to defecate and then you will be rinsed again with clear water, but I will explain that to you when we are ready. Now stay completely relaxed, you'll change position straight away so that the enema is well distributed in your bowel," explained the doctor's assistant. Chiara whimpered softly. By now she was sticking her ass out in exemplary fashion - minute by minute more enema broth was flowing into her through the transparent enema tube. Moritz looked at his best friend with pity. He could only begin to imagine how embarrassing the whole procedure was for Chiara.

"Auaaa, my tummy is starting to hurt," the girl said to Moritz after a few minutes, whimpering. "Yes, that's quite normal, the soap irritates your bowels and triggers cramps. But don't worry, it'll go away, it's just funny in your butt at the moment," Moritz replied. Maria meanwhile checked with a stern look whether the double balloon tube was really firmly in Chiara's butthole, although there was no doubt about that, as tightly as her tight anus clutched the inflated rubber balloon.

"Now you can carefully turn onto your back, keep your legs nice and wide, then I'll place the tube on the couch between your legs. The soapy water should spread nicely in your bowel and loosen your faeces, there seems to be quite a lot in there anyway," the assistant instructed. Without a word, the young patient performed the half turn while Moritz positioned the tube between her legs. The balloon in her rectum and the attached tube virtually forced Chiara to keep her legs apart, which also caused her labia majora to spread slightly, revealing her vagina. The more of the enema broth flowed into her butt, the more Chiara moaned. She instinctively pulled her legs slightly towards her body, as the foreign body was pressing so hard in her virgin asshole. Meanwhile, the patient's stomach was already gurgling and rumbling audibly.

"Now do another half turn, head towards me and stretch your bum towards the wall. Then the fluid can work its way inside you," Maria ordered. Chiara had started to sweat even more in the meantime due to the increasing pressure in her arse - beads of sweat had already formed on her forehead and her whole naked body seemed to glow with excitement and shame. The young woman also acknowledged the change of position with a loud groan. Moritz stroked her naked buttocks again and again to calm her down a little. Chiara looked anxiously at the enema bag, which was still more than a quarter full, and moaned: "Ahh, I can't do this much longer, the pressure in my bottom. Please, I have to go to the loo urgently". Maria, however, was not impressed by her patient's wailing - she was probably far too familiar with the moaning and groaning of young girls lying naked on this couch with a bowel tube up their rectum. But the enema bag knew no mercy until the liquid had completely drained out.

"Almost there, there's not much left," Maria encouraged her patient, "now it's getting uncomfortable again, please stand up, we'll give you a quick tummy rub". Moritz could hardly believe his ears - Chiara was supposed to stand up now? Her tummy had even bulged due to the enema fluid and she really had a lot of soap in her butt now. "Hey, you have to stand up again at the end. Come on, I'll help you," said Moritz and took both her hands, which had also become quite sweaty from all the excitement. "Auaaa, it hurts so much," Chiara screamed as she stood up from her lying position. Moritz pulled her up so that she was standing on her legs, albeit rather unsteadily. Now it was even more obvious how much her stomach was bulging. The 21-year-old stood there with her face contorted in pain, while Maria looked contentedly at her bottom, in whose narrow opening the double balloon intestine tube was still securely wedged. "It all looks very good. Now the gentleman can put his hand on her stomach and massage it a little so that the enema is distributed nicely in all areas of the bowel and the cramps subside a little thanks to the massage," said Maria.

Moritz carefully massaged his best friend's bulging belly and watched her reactions - he certainly didn't want to hurt her. He felt sorry for her, because as the last drops of the enema flowed from the bag into her arse, a tear rolled down Chiara's cheek. "Now it's empty, I have to go to the toilet quickly!" said the naked girl angrily. Moritz looked questioningly at the doctor's assistant and translated back into English. Meanwhile, Maria removed the tube from the double balloon bowel tube so that Chiara was no longer connected to the enema bag, even though her bottom was still securely sealed by two inflated balloons.

"The enema has to work for another 10 minutes, you have to hold out for that long, then you can empty yourself here," Maria said dryly. "Here?" Moritz asked in surprise.

"Yes, that's right, Chiara will empty her bowel contents into a bucket here in this room. This has proved successful for our patients' enemas. The route to the toilet is all the way down the corridor and most of them can't cope with the enormous pressure in their bum once the bowel tube is out. We don't want to end up with a brown mess outside in the corridor. No, the girls empty themselves into a bucket here - it's easy and quick. They don't think much about it anyway, it comes out of their bumhole all by itself, believe me. I'll leave you alone for 10 minutes and get everything for the next steps, then I'll bring the bucket with me. Don't do anything stupid and be good and leave the tube up your arse," said Maria and left the room.

Without further ado, Moritz translated the gynaecology assistant's announcement. Now he had 10 minutes all to himself with his best friend, who had just had one and a half litres of soap broth pumped up her ass stark naked. He couldn't believe that she would shit in a simple bucket or empty her enema after the exposure time and that he would be there live.
