Medicinal Calling

Inside the Equestrian healthcare system, as any system worth of its salt, has many regulations to make sure that the staff is prepared to face any hurdle or emergency that their job might entail, ranging from the ones regarding the patients proper to the everyday professional life. In the former category, there is a set of strict rules on the proper way to interact with a patient, forbidding, for instance, the formation of romantic bonds or attempts at exploit a patient's vulnerability for any kind of personal gain.

Nurse Redheart, after little more than a decade working in Ponyville's Hospital, had learnt them by heart, but she made sure everyday to mentally repeat that particular part of the rules.

To the outsider, she was not anything more than her job, just taking care of patients until their recovery or death. To the colleagues, she was an useful asset with the quirk of a penchant for taking the posts in pouliatrics. But no outside glance or workplace bonding can reveal somepony's deepest desires, and Nurse Redheart was taking extra care in not letting her biggest one out.

Her little mantra was just part of her way to keep that desire away, to make it accept to only watch but not touch, especially when it came to the more invasive and degrading procedures.

With the repetition done with for that day and after she had consulted the timetable at the nurse station, she had gone to the gastroenterology ward, set up the small clinic, and then sat down on the desk's chair, waiting for the first visit's time to arrive.

When it came, she walked forth, towards the door, and opened it slightly, revealing only Rumble, looking dejectedly to the floor.

Heaven knew where his parents were, but the truth was, they weren’t there and he was clearly not looking forward to be examined, especially not the way it was awaiting him.

"C'mon Rumble, it's time for your exam." She said, smiling at him, while also trying to grin at herself. The colt sighed and climbed off his seat, walking slowly and with his head pointed to Redheart.

"Did you remember to not eat yesterday and today?" She asked, as he lead him towards the examination table covered in waxed paper above a plastic sheet on top of more paper protecting the precious black rubber surface. He nodded, as he climbed upon the table, standing on all fours and lifting his tail, revealing his smooth, little balls and his black-and-pink precious sheath, as well as his juicy and tight plothole.

Nurse Redheart licked her lips fugitively, only to shake her head right away to then tell him to lay down onto his belly and spread his legs open in order to give her a better way to access his innards. Rumble shifted his legs open very slowly and carefully, his buttcheeks visibly contracting themselves as soon as his hooves were in position and his butthole and his nutsack had become fully visible to Redheart.

Nurse Redheart took a couple of seconds to savor the sight, before going to the cabinet next to the door, to extract a can of lube, a pair of rubber gloves, a metal breechblock and a long elongated box, labeled as "endoscope kit." and then to carry them next to the examination table. Rumble's face took a slight shade of red at the mere sight of those items, which prompted Redheart to pat his head and stroke his black mane, which felt like velvet to her touch.

"Don't be embarrassed, sweetie," she said, before snapping the gloves on her hooves, using her mouth to help herself in such an operation and then unscrewing the can to dip her hoof into it. "It's a standard procedure, nothing to be worried about."

Rumble weakly nodded, his buttcheeks clearly clenching and relaxing slowly, which only made his anal entrance even more obvious. She fugitively licked her upper lip as she spread the lube around and a bit inside his ass, rubbing her coated hoof onto the meatier part slowly, before pushing her hoof's tip inside, circling around as she felt the dank walls of Rumble's anal cavity instinctively clench on her hoof while he let out a squeak and blushed bright red for a few seconds. She kept going for a two full minutes, a little longer than necessary, lost in thought about what else his lubed butt could be used for. She had a job to complete, however.

"Alright, now that your tushy is all ready for inspection, let's get to it," she said, moving her hoof out of him and assembling up the endoscope instead, placing the visor on one end of the tube and screwing it firmly in position, before grabbing the penetrating end and inserting the first few millimeters inside Rumble, producing a gasp and an instinctive reaction to clench down onto it -- in the vain attempt to push it out of the way -- from him. Nurse Redheart grinned coyly as she placed the visor on one eye and at the same time pushed the instrument inside him, unrolling its black rubber snake of a tube in the process.

Rumble squeaked, squirmed in place and blushed as the endoscope went up his innards, stopping a few times for Redheart to take a deeper look, before resuming, until it was well inside his small intestine, at which point she stopped, giving an attentive stare to where she was inside him. However, when she had determined he didn't have anything wrong inside him, Nurse Redheart decided to not just pull it out of his intestines jus yet: she wanted to look at his current position a little first.

Peeking away from the instrument's visor she looked downwards at Rumble, where she saw his lubed-up butthole still being penetrated by the tube, which kind of looked somewhat like a squid monster's tentacle to her. And, given how he was reacting to it, it might as well have been so.. not that she minded.

Now her thought started to actually picture such a scene, imagining the endoscope's upper part to slowly turn into a octopus' head and to grow a few short tentacles around its head while the long tube was just a very stretched-out appendage of itself that had managed to slither its way into the colt, poking around his ass' bowels' walls, stimulating his prostate just enough to give him a boner but not long enough to make him cum, leaving him whimpering as the thing just kept crawling further and further into his body, and just as the other sinuous appendages extended themselves to instead stimulate his small balls and to give slow, tickling caresses to his sheath's outermost tip, prompting him to quiver and moan as he started to feel feelings he was unlikely to understand, sensations that with some more methodical stimulation and some nice rubbing, were going to allow him to expel sperm for the first time in his short life.

She felt her lower lips moving and, nearly instinctively, brought her left hoof closer to her nether parts, ready to satisfy the itching urge. Her trembling hoof got closer and closer to its destination and a small strand of drool dripped from her mouth...

"Uhm... are you done yet?"

Rumble's voice kicked her out of her lustful trance, prompting her to shake her head and move her hoof away from herself, only to glance and then stop on his small tender nuts. A huge blush grew on her face as she quickly realized what had just happened, feeling a pang of satisfied arousal at the mere memory and the thought she could get away with that action.

"Oh, very soon Rumble," she said, forcing herself to suppress a smirk, as she carefully gave a squeeze to his left nut, feeling the gonad beyond the scrotum and thinking just how much of the good stuff it could produce once he was going to be older -- or could be producing right then even -- and at how soft at touch that patch of coatless skin was. "Juuust another little peek, then we're good."

Rumble seemingly felt that touch, since it had squeezed his eyes closed for a few brief seconds but, pretending she hadn't noticed it, she started to slowly and carefully pull the endoscope out of his anal cavity and intestines. Each millimeter came out dripping in lube, which only prompted Redheart's mind to go in deeper places, and every centimeter that was pulled out made him moan a little, until it was fully out, at which point he sighed deeply with his tongue stuck out.

"It wasn't so bad, was it?" She asked with a warm smile as she took her gloves off to drop them in the nearby trash bin.

"N-no... it wasn't. It was pretty odd, though." He said, moaning as he closed his closed his legs back up and then climbed down the examination table, stretching his legs a little. "So, what's my problem exactly?"

"You don't have anything wrong inside your innards, in fact, you've got a pretty healthy intestine." Redheart said, patting his head and caressing his soft mane. "Probably you're going to need to go through further exams, maybe a blood draw, maybe an urine sampling."

"Actually... I had them, they just didn't arrive yet." He said. "Anyways, am I done now?"

"Yes you are," she said. Rumble immediately went for the exit without even saying goodbye. Redheart sighed as she went back to sit behind the desk.

"Let's write this down, then...." she muttered to herself as she sat down. "This visit was pretty... interesting, I have to admit. Oh Celestia, how lovely it felt to touch his nutsack like that! Oh, such a sensation! And I probably won't feel the same feeling again: after all, I have to restrain myself..."
