Moritz struggled to hide his excitement and amazement. ‘But Chiara's tight ass won't be spared anything today,’ he thought to himself. The patient's tight, albeit somewhat stretched, sphincter had closed again. Visibly relieved that the examination instrument had left her anus again, the 21-year-old was still lying on the shabby-looking gynaecological chair with her legs spread wide apart. Shortly afterwards, however, Dr Sanchez released the restraints on her thighs and told her to get out of her awkward position on the gynaecological chair. No further words were needed and Chiara lifted her legs out of the shells and closed her legs again within seconds. Finally no longer so exposed between her labia and finally no more having to endure constant glances at her anus - the young patient thought to herself. ‘Are we finally finished?’ Chiara asked, half annoyed and half frightened.

The gynaecologist was still tidying up the used anal speculum and apparently sorting something on his shelf, but this was hidden from Chiara and Moritz's view. The young patient had now been naked for at least three quarters of an hour - including the embarrassing enema procedure and the two bowel evacuations. Chiara sat on the surface of the monstrous examination chair, pressing her thighs tightly together. Her bare legs dangled just above the floor and her buttocks stuck to the paper on the examination table, most of which was already soaked with the lavishly applied lubricant from the rectal examinations. However, the pretty 21-year-old couldn't completely ignore the slippery and slippery feeling in her anal area, between her buttocks and in her anus. After all, she hadn't had a chance to wipe away the lube. She shyly tried to cover her breasts with her hands - so despite the humiliating rectal examination, her natural shame was not completely broken. ‘Everything's fine so far, but we still have one last examination to do. We're ready on the gynaecological chair. Please kneel on all fours on the examination table again, spread your legs wide and stretch your bottom upwards,’ the college gynaecologist announced relatively dryly.

Moritz translated the instructions for Chiara and tried to encourage her again: ‘One last examination, you'll have to kneel down on the couch again. I'm sure it won't be too bad and it'll go really quickly’. Visibly resigned, the naked patient got up from the gynaecological chair and plodded to the couch. ‘I've really run out of nerve, it's all too much for me and infinitely embarrassing. My butt hurts. What else does he want to examine, he's already seen everything in my ass?’ said Chiara in a broken voice. Moritz took her arm and accompanied her the few metres to the examination couch, whose leather was already very worn and didn't look very comfortable. ‘I don't want to show my anus any more,’ Chiara cried, wiping a tear from her face. ‘Come on, get on the lounger and kneel down! Spread your legs and keep your butt nice and high! The last examination is compulsory, I'll explain it to you as soon as it starts,’ Dr Sanchez now spoke rather impatiently and gave Chiara a slap on her left buttock. In the most submissive of all positions, she was now to expose her anus again for further examination. Chiara quickly climbed onto the examination table and assumed the required position, which seemed to reduce her to something animalistic when she was stark naked. Her small buttocks parted of their own accord as she spread her legs, her breasts hung down and her head lowered towards the examination table. She wasn't prepared for what would happen now, as she couldn't see what the gynaecologist was preparing behind her bottom compared to the examination on the gynaecological chair. ‘What else is going to be examined on my rectum?’ Chiara snorted angrily. At that moment, Moritz saw what the doctor had taken out of the previously concealed tray of rectal examination instruments and positioned himself behind his patient's anus.

A rigid proctoscope at least 20 centimetres long, which was frightening just to look at. Moritz swallowed and wondered how this examination instrument was supposed to fit into Chiara's tight asshole. But it had to fit into her bottom, as the gynaecologist's rigid approach had left no doubt about that so far. ‘During the first rectal examination here at the health centre, it is mandatory in Peru to examine the patient rectally with two independent examination instruments to check the health of the rectum. With the proctoscope, I can look much deeper into the patient's rectum than with the anal speculum, with which I was able to spread open the butthole to take a closer look at the rectum. The proctoscope allows an even more thorough examination of the bowel,’ explained the doctor. Chiara jerked back and forth very restlessly. ‘Please spread your legs to the very edge of the couch!’ said the naked patient, who seemed to have fallen into a trance of shame. Slowly, centimetre by centimetre, her feet moved further towards the edge of the shabby examination couch. Her small buttocks opened slightly again due to the generous spread of her thighs and her labia no longer seemed to be completely closed. ‘The grand finale was about to begin. The final and maximum penetration of Chiara's tight anus’, thought Moritz, his heart beating faster and faster. Dr Sanchez had the long proctoscope, the rigid and unyielding butt tube, in one hand.

With her other hand, she touched Chiara's head, which was glowing with shame, and pushed it down a little further so that the 21-year-old was looking at the worn leather of the couch while the tip of the lubricated proctoscope was only a few centimetres away from her anus. ‘The friend will also assist with the last examination, please. Please spread her buttocks as wide as possible - I will then insert the examination instrument rectally. Please also stabilise the patient's pelvis a little if she becomes restless,’ instructed the college doctor. Without thinking any further, Moritz grabbed his best friend's sweet butt cheeks and pulled them wide apart. Chiara twitched slightly - she was now completely accessible again at the back. Her sphincter, glistening with lubricant and looking a little irritated from the previous examinations, was visible to everyone watching. Her bottom hole had been through a lot today and her anal area was redder than before the enemas, Moritz thought.

‘And here we go, please loosen your sphincter again, press against it a little and clench your teeth! We will now begin the final inspection of your bowels,’ said the gynaecologist. Moritz gently stroked the inside of both of the naked girl's buttocks with his thumb: ‘You'll manage, you have to be strong for once! Keep nice and still.’ When Chiara felt the cold metal of the long proctoscope against her anus a few seconds later, she sobbed and whimpered again in her humiliating position. ‘Ass up, face down,’ Moritz thought spontaneously. There is probably no worse and more embarrassing position for a 21-year-old naked girl who has to have a long metal tube shoved up her tight ass. And it's compulsory - without any ifs or buts. And then the butt tube made its way into her rectum: centimetre by centimetre, the unyielding rectal examination instrument disappeared into Chiara's butt hole. ‘Auaaaaaa...that burns! My bum! Stop it!’ the naked patient screamed like a banshee. Her toes cramped up, her palms drummed on the couch and her abdomen instinctively jerked a little further forwards.

While the gynaecologist continued to quickly insert the proctoscope into her rectum and Chiara reflexively tried to crawl forwards on her knees, Moritz held her buttocks firmly and held her back. But she kept jerking her knees forwards, which the college doctor didn't like at all. He gave her a slap on her left buttock: ‘Hold still now, otherwise it will get even more uncomfortable!’. Chiara was persuaded to hold still by the slap on her bottom. She only whimpered softly while the doctor inserted the proctoscope all the way into her rectum. He switched on a light at the front end and was able to look even deeper into her bottom than before with the anal speculum. Chiara's pink intestinal walls nestled tightly around the metal tube that had penetrated so far into her most intimate orifice. She felt impaled - and at the mercy and helpless. This rectal examination felt like a painful, involuntary anal deflowering. And in a foreign country, by a doctor who didn't even speak her language and was now seeing parts of her body that no one else had ever seen before.

Chiara moved her naked butt back and forth in agony. In return, the gynaecologist also moved the proctoscope in her butthole, repeatedly pulling it out a little and back in again to meticulously examine the bowel area and not miss a single square millimetre. The bulge in Moritz's trousers, on the other hand, seemed to be getting bigger and bigger. He continued to hold his best friend's buttocks tightly apart, giving the metallic intruder free rein at her anal opening. The agonising spectacle went on for another three minutes or so, between the odd loud, moaning ‘Ouch!’ from the naked patient. Then, finally, the gynaecologist seemed to have completed his final rectal inspection of Chiara's rectum. He slowly pulled the examination instrument out of her formerly virgin bottom and wrapped it in a paper towel. The completely exhausted 21-year-old slumped down on the examination couch, crying, rolled onto her side and held her hand to her butt crack. Moritz stroked her lightly and said appreciatively: ‘You were very brave, now you've finally got through it!’.
