With a red head, the naked girl listened to the doctor's assistant's announcement. Still holding her hands shamefully in front of her vagina, the 21-year-old was overcome with goose bumps all over her body. There was no way out. She would have to endure whatever the Peruvian guidelines dictated while stark naked. Maria pointed to the somewhat shabby-looking scales that stood not far from the couch. Without giving it a second thought, the young patient plodded over to it and stood on it with the soles of her bare feet. There was really nothing wrong with her weight, because Chiara is a slim and well-trained girl whose body all boys would probably like to see undressed. After the assistant had noted Chiara's weight, she was asked to stand with her back straight against the wall. "Now I'm going to measure you quickly, that's also part of our routine for every patient, regardless of what the gynaecological examination will focus on later," Maria said as she measured Chiara's height. The 21-year-old was visibly uncomfortable having to endure even this routine procedure without any clothes on.

"So, Chiara, now it's time for the actual preparations for your upcoming examination. Please come over to the couch, where we will start by taking your body temperature. To do this, please bend your upper body over the couch, support yourself with your elbows and stick your bottom out nice and wide". Moritz's eyes widened when he heard this. The assistant apparently wants to take Chiara's temperature in her ass, how embarrassing! And he's going to be up close and personal as something is inserted into his best friend's bottom. "But... that's not possible, why take a temperature in my butt, then they'll see my ass..., no that's not possible," Chiara stammered uncertainly in German. Moritz didn't even need to translate this into English as Maria could see the young patient's nervousness and embarrassment. "It has to be done, the rules are the rules. And in Peru, every girl's temperature is taken rectally by the gynaecologist. So hop, hop - bend over the couch and bring your buttocks to me. It won't hurt, at most a little uncomfortable, but that can't be avoided. I'll also put some Vaseline on the thermometer, if that calms you down a bit, then it will slide into your anus better," the doctor's assistant remarked. Moritz looked at Chiara sympathetically and told her that she wouldn't be able to avoid having a clinical thermometer inserted into her bottom.

The girl stood unsteadily in front of the couch and stared in bewilderment at the green leather surface. Moritz put a hand on her shoulder and whispered in her ear: "Come on, it won't be that bad. She said herself that it won't hurt. I know how embarrassing this is for you right now, but you have to get through it. She'll put some Vaseline on the tip too." Sobbing and with tears in her eyes, the young patient approached the couch and bent forwards very slowly. Moritz's hand continued to press her back down until Chiara was able to support herself with her elbows. Her inner resistance was palpable, but it was no use - the naked girl needed to be guided into the desired position. "You're doing great, now stick your bottom out a little further so that the helper can easily reach your sphincter with the thermometer," whispered Moritz. Chiara closed her eyes and stretched her bottom a little further forwards while at the same time she felt her little bum cheeks seem to open up on their own and air reached her anus.

This moment of absolute shame was only interrupted by the snapping sound of rubber gloves that Maria was putting on. Suddenly she felt a slap on her right buttock, causing Chiara to flinch in shock. "Spread your legs a little further apart and support all your weight on your elbows, keep your bottom nice and far out," the helper ordered in a stern tone. Moritz carefully grabbed Chiara's inner thighs and helped her to spread her legs even wider. She spread her legs a little further apart so that her private parts were even more exposed to view. It was quite tingling for Moritz to reach just a few centimetres under the genital area of such a pretty girl.

She was now perfectly positioned: Her flawless buttocks as if on a platter for two people, one of whom had already prepared a rather rustic analogue clinical thermometer with some Vaseline. The doctor's assistant firmly grabbed Chiara's small buttocks and spread them apart. The 21-year-old flinched again when she felt the latex of the rubber gloves on her body. Moritz, however, held his best friend in position with his hand on her back and her legs stayed nice and wide apart. "Now she's looking directly at my asshole and I can't do anything," Chiara thought to herself as the helper scrutinised her anus with a stern look. She grabbed Chiara's buttocks several times, spreading them in different places to explore every corner of her anal area. Her pink sphincter was tightly contracted and resisted any intrusion - until now. "You're already clean-shaven, so we don't have to go there again. I can't see anything unusual about your bottom from the outside," Maria remarked, "I'm going to take your temperature in your anus now. Please take a deep breath and stay still. It's best to press against it a little, then it will slide in further and be more comfortable for you. The menacingly long and relatively robust clinical thermometer moved swiftly towards Chiara's rosette. Moritz could barely finish translating before the young patient felt the probe on her anus: "Here we go, she's going to push the thermometer up your bottom. You should press against it a little so that it goes in nicely. Just keep breathing calmly".

Chiara's head had turned bright red with embarrassment, her entire attention now focussed exclusively on what was happening at her rear end. When she felt the probe on her butthole, she closed her eyes - every fibre of her pretty naked body was resisting having something inserted rectally in a foreign country and so unexpectedly at that. Chiara tried to relax her anus and press lightly against it, which she halfway succeeded in doing. The clinical thermometer quickly made its way into the young woman's bowel. She was disgusted by the feeling of having something inserted into such an intimate orifice against her will. After Maria had already pushed the measuring device a few centimetres deep into her bottom, Chiara couldn't avoid a soft moan and moved her bottom slightly towards the couch - but there was no escape. Her exposed bottom was trapped between the couch and the thermometer and two people made sure it stayed that way.

Moritz looked excitedly at the analogue thermometer, which was disappearing further and further into his best friend's bottom. "Wow, now only the tip is sticking out and the thing is several centimetres up her bum, it's a really cool sight," thought Moritz. When Maria had inserted the thermometer far enough into Chiara's bum to her satisfaction, she took her hand away. The 21-year-old's tight sphincter clasped it and ensured that the foreign object was held in her ass without any further aids and did not need to be held in place. "Now Chiara, this will stay in your bottom for three minutes, then I'll pull it out and take your temperature. In the meantime, I'll ask you a few questions, this is important as preparation for the examination later. The doctor always wants to have a few things clarified in advance before he gets down to business. Let's start off easy, I'll make a quick note of your answers. Have you ever had a rectal examination before, i.e. through your anus?".
