"Double Diamond?"

The stallion was snapped out of his stupor by the sound of his name being called. He quickly lifted his head, glancing instinctively around the clinic's waiting room before noticing the mare to his right, wearing a nurse's hat and looking expectantly at him.

"Just through here," she continued with a little smile, motioning along the corridor with her head. With a quivering breath, Double Diamond stepped down from his seat and followed the white-coated nurse a short way to what was, presumably, her office. She held the door for him, letting him by before allowing it to close behind her. The room beyond wasn't too large, but it did contain - among other things - some sort of examination chair, a little tray with various surgical implements neatly laid out, and a small desk for paperwork. The smell of disinfectant was heavy in the air. "Have a seat," she pulled the chair out on his side of the desk, taking her seat opposite him while Diamond nervously did the same.

"I'm Nurse Redheart, and I'll be performing your procedure," she began with a gentle smile, her sky-blue eyes lightly marked by crow's feet, and neatly framed by a light-pink mane tied up in a loose bun. "Before we begin, could you tell me a little about why you're here today?" she asked, taking a few sheets of paper from the desk and glancing over them.

Double Diamond glanced away awkwardly. He thought he'd been over this when he made the appointment, or with the receptionist. "Uhm, well... I'm here for my... To get, uhm... gelded..."

The nurse looked back up at him, just managing to suppress a chuckle. "... Yes, that, I'm aware of. I was referring to the reasons behind your decision. It's none of my business, I know, but I do need to make sure that it's right for you, okay?"

Diamond felt himself blushing a little at his mistake - but the nurse was right, of course. This wasn't something to be taken lightly.

"Well, uhm... See, the thing is... I'm not exactly a foal anymore and, well, I haven't had too much luck with mares..." Or any luck, for that matter. He felt his blush growing by the second as he explained his predicament. "And, well... You know how it is, it doesn't get any easier as you get older, everyone expects you to... well, to be a stud, and since I'm not... And when the Rut comes around, i-it just drives me crazy, I can't even be around mares, or I might... y-y'know... in public..." Diamond shrunk into his seat, burying his head in his scarf.

The nurse nodded slowly as he spoke. "I see. Well, social concerns, like you're describing, aren't an uncommon reason for getting this procedure. It's nothing strange at all," she added with a little smile. "Now I'm sure you're aware of all this, but I need to go over the effects face-to-face..."

Diamond nodded. He knew what was coming, naturally, but it didn't hurt to avoid any surprises.

"The intention, of course, is to reduce your sexual function as much as possible. You will be fully infertile and impotent; so no more erections, which will make both intercourse and masturbation essentially impossible - and in any case, you will be unable to climax or ejaculate."

The stallion felt himself shiver as the nurse talked so matter-of-factly about what was going to happen to him. Each word, spoken serenely and directly just inches from his face by the mare who would in mere moments be literally castrating him stirred up a cocktail of emotions, and Diamond found himself forcing his hind legs together in an attempt to hide his now very visible arousal.

"Other, secondary effects can include changes to your voice, your mane and coat, and your personality. And, since you mentioned it, you should only be minimally affected by Heat and Rut going forward," the nurse added, giving him a pleasant smile. "Finally, of course, there will be a clear visual distinction in your rear end," she continued, smiling and lowering her head for a moment, "so you should expect ponies to treat you a little differently from today. But in your case, this shouldn't be a problem?"

"Mhm, no... n-not at all!" Diamond shifted in his seat as he tried to return her smile, made more difficult by his repeated, vain attempts to calm his erection by tensing his muscles. Hopefully there would be some sort of form to fill out, more questions to answer to give him a little more time...

"In that case, let's move over to the chair here and we'll get started." Diamond felt a sudden rush of anxiety as the nurse walked over to the examination chair, tilting it back and pulling both hoof-rests away from the middle. He sat in total silence, quivering, for several moments before the nurse finally spoke again.

"Look, I'm sure you're nervous, but the sooner we start, the sooner it'll be over," she continued, tilting her head a little.

"Ah... Yeah, I... I guess so, heh..."

Diamond felt his heart pounding as he slowly walked over, taking as long as he could to hang his scarf on the nearby rack. He climbed awkwardly onto the chair, trying to cover himself with one hoof while using the other to hoist himself up, but as his body shifted his erection slipped from his grasp, springing upwards distressingly close to the nurse's face as he scrambled to pull it back again. Despite all her experience, Redheart couldn't help raising an eyebrow. "I'm... so sorry...!" Diamond squeaked, tears forming in his eyes as his face burned red with shame.

"It's okay," the nurse replied, doing her best to be comforting while stifling a chuckle, "This is... surprisingly common, in fact." She paused for a moment, considering his situation. "For young stallions like yourself, I think the easiest solution would be to find a quiet spot and... take care of it. Does that work?"

Diamond somehow felt even more embarrassed by the suggestion, but he found himself nodding in agreement.

"Go left along the corridor, then to the second door on the right; sample room two," Redheart continued, her smile dropping to a sympathetic, professional expression. "Take as long as you need, and I'll have everything ready here when you're done."

Double Diamond nodded quickly, dropping down from the surgery table and pushing through the door without another word, his hind legs pressed together as he walked. "Have fun~!" He cringed as he heard the nurse call out behind him, just as the door closed the last few inches. Fortunately, the corridor seemed empty, and no-one passed him as he followed the nurse's directions, making his way to the door she'd indicated and closing it firmly behind him once he entered.

The room beyond was very small, with just enough room for a plastic-cushioned bench and a little shelf of 'reading material'. Not that he needed it, of course; once he'd hopped on the bench, letting out a trembling breath as he finally spread his legs to reveal his erection in privacy, he needed only to let his eyes sag half-shut and picture that same pink-maned mare, smiling suggestively as she eyed him up on the table.

"Oh my - a little pent up, aren't we?" she giggled, prodding his erection with a hoof before slowly lowering her head to meet his crotch.

Diamond's hoof began to stroke the underside of his twitching cock, his body aching as he tried to hold himself back, to let his fantasy play out for a few moments longer.

"Well, I can take care of that for you... Just don't tell anyone, okay?" With a mischievous wink, she pressed her lips against Diamond's throbbing member, dragging her hot, wet tongue along the sensitive flesh. "After all, this is the last time you're going to feel anything this good..."

"Ah...!" Diamond couldn't hold back a moan, biting his lower lip hard to silence himself as his hoof strokes increased in speed, wrapping around his shaft and squeezing from base to tip.

The nurse reached the tip of his cock, her lips widening to take him into her mouth, enveloping him in a soft, warm sensation, while her tongue slid against the underside. It was too much; he felt the pressure begin to rise, his body heating up...

Click

The light from the corridor shone against Diamond's half-lidded eyes, the brief flash of a blue-coloured pony outside...

"Aaah!" He bolted upright, slamming the door shut with both hooves, even as his cock squirted ropes of gooey seed from his last ever orgasm onto the wall. "O-occupied! Occupied!"

He heard a mare's high-pitched gasp from behind the door. "S-sorry!" he heard her reply, shocked and breathless, before trotting immediately and rapidly away, leaving him alone in silence once again, his member giving one last limp squirt as his climax ebbed. Diamond scrunched his eyes together. "Fuck fuck fuck..." His painful chagrin at the interruption was matched only by the bitter regret upon noticing the un-engaged door lock, which would surely be mirrored by an indicator on the outside.

With a deep sigh, he gently twisted the lock and turned his attention to the pool of semen covering the wall and floor. Fortunately the room was well-equipped with tissues, and a few shameful minutes later, Diamond managed to clean most of it off - though a thin, sticky residue stubbornly remained. He resigned himself that some unfortunate cleaning pony would have to deal with it, before leaving for the surgery room once again, silently praying that he wouldn't bump into that mare, whoever she was, on the way. This time, at least, luck was with him.

"Ah, there you are. Everything taken care of?" Redheart asked as Diamond re-entered the surgery, now sitting on a round stool, with latex gloves covering her forehooves.

"Mhm... yep!" he replied, forcing himself to smile as he hopped back onto the table, doing his best impression of someone confident and easy-going while placing his hooves against the plates and spreading his legs out once again. His member, though soft, still hadn't fully retreated into its sheath, and while he'd done his best to clean up, his eyes were drawn to one final droplet of cum forming at the tip. He quickly forced himself to look away as a blush rose to his cheeks, but the nurse didn't appear, at least, to notice.

"Good," she replied, her lips forming an easy smile, "then we can get started." Taking a little white cloth from her tray, she lifted his shaft with one hoof and began wiping his pouch with the other. Double Diamond felt a sharp stinging sensation where she wiped, but despite his recent climax, the sight and sensation of the nurse handling him was enough for his cock to stiffen up, if only slightly. As the nurse pressed the back of her foreleg against him, tightening the skin to allow her to push a syringe needle at the point where his pouch joined the shaft, all Diamond could focus on was that tiny rivulet of cum dribbling down onto her hoof. He could feel his cheeks swelling by the second, his whole face burning red as he stared at some unfocused point on the ceiling, even as his eyes darted down to steal a glance at the procedure.

"Alright..." Redheart began, gently replacing the syringe on her tray before picking up, with that same professional serenity, a pair of odd-looking metal tongs, a circular blue band stretched between the arms. Diamond gulped. This was it.

"Ready?" He nodded quickly, forcing his eyes shut; despite how life-altering and likely painful this was going to be, at this point he just wanted to get it over with as soon as possible. He felt the nurse gently manoeuvre his balls within the band, the cool touch of metal against his shaft as she pressed the tool against him, then...

Snap

The sensation was surprisingly painless. Whatever the nurse had injected was doing its job well; the only thing Diamond felt was a firm tugging around his erstwhile foalmakers as the band squeezed tightly at the top of his pouch. He felt his half-erect cock twitch with the sudden pressure, and another wave of embarrassment washed over him... At least he wouldn't have to deal with that for much longer.

"We'll leave that for a minute or two, okay?" The nurse gave him a little smile as she surreptitiously cleaned her hoof, before moving back to her desk and starting to fill out some paperwork.

For a while, the only sounds were the barely-audible hum of the clinic's magical lighting, and the soft scratching of the nurse's pen on paper. Diamond could do nothing but stare up at the ceiling, taking slow, deep breaths as his heart pounded, his recent embarrassment being gradually replaced with a subtle, tense anxiety. He wanted to think, to process the last half-hour, to imagine how his life was going to change from now on, but the jumble of thoughts in his head combined with his mid-surgery nervousness made that thoroughly impossible. All he could do was stare at that ceiling, focusing on the blankness in a vain attempt to distract himself from that ever-present tension in his nethers...

"Okay..." Nurse Redheart began, standing to face him once again, that same soft smile on her face. "I think that will have done it. You're officially a gelding."

"I... W-what?" Double Diamond's face was shot with confusion. "There's not, uhm... Isn't there... more to do?"

"Well, of course," she replied, his dumbfounded expression eliciting a little chuckle, "but it's just clean-up, really. It only takes a few minutes of cut circulation for the effects to be irreversible. In theory you could just leave the band on, let everything atrophy and detach naturally, but it's safer to do it here in the surgery - plus, I can stitch you in a way that should minimise visible scarring."

Diamond's heart sank as she spoke. With trepidation, his eyes slowly glided down to his crotch, resting on his pouch beneath the band, now tightly swollen and visibly purple. In the dark reaches of his mind, he'd thought that there was somehow still time to back out, but... Gelding... That's what he was, now. Forever. All the reasons for getting this done that once seemed so logical, so pressing in his mind now seemed to vanish into irrelevance in the face of the one inescapable fact that he was no longer a stallion; that a vital, precious part of him had been lost forever; that he'd never sire foals, never please a mare - Sisters, he'd never even jerk off again...

"It's okay," the nurse softly spoke, evidently noticing the obvious heartache on Diamond's face. "It's perfectly normal for new geldings to feel a sense of loss - regret, even. For now, my advice would be to remain as calm as you can; take a few deep breaths if you need to. Once we're done here, find something to occupy your mind for a few days until everything settles down. No point in dwelling on your worries now, is there?"

Diamond supposed not. He nodded glumly to the floor, breathing for a few moments as instructed before lying back on the chair while Nurse Redheart wordlessly returned to her tray, snapping a fresh, sterile scalpel blade onto a hoof-handle with a single, delicate motion. Diamond's eyes snapped back to the ceiling. Even if it was, as the nurse put it, 'just clean-up', he really didn't want to watch this part.

"You shouldn't feel anything - just pressure and a little scratch."

Diamond's hind legs tensed up as he felt the blade against his skin. The combination of the anaesthetic and the band was more than enough to block any pain, but he could still hear the sound and feel the faint sensation of something slicing into his flesh; not to mention the even stranger feeling of someone pulling and manipulating things inside him. A little while later, Diamond heard the soft 'plop' of something fleshy landing on a metal surface, and he instantly closed his eyes tightly. He'd heard - though it must almost certainly be a myth - that some geldings would actually keep them, like some sort of macabre souvenir. Fortunately, the nurse wasn't inclined to suggest this.

"Just the stitching now. Not much longer." Diamond felt himself breathing out at last, as if the weight of some huge responsibility had been lifted from him. He could hear the faint sounds of threads passing each other, and the occasional snap of scissors, until the nurse returned her instruments to the tray just a few minutes later.

"That's it - all done!" She beamed up at him, her smile matching the relief in Diamond's chest. He let out another shaky breath before stepping down from the chair, his hind legs wobbling dangerously. Redheart held his shoulder for a moment to steady him. "Careful - take it slow, okay? You've been through a lot," she added with a chuckle. "Now, do you want to take a look?"

She motioned towards the surgery's wall-mounted full length mirror, which Diamond gingerly approached, turning himself around and slowly lifting his tail...

His conscious mind had long understood what had happened to him, but seeing the visible effects in person was something else entirely. His taint was completely smooth from his tailhole to the base of his sheath, aside from a single, delicate line of stitches. Once they'd healed, it would be like his foalmakers had never been there at all. Despite his inner turmoil, Diamond couldn't help marvelling at the nurse's work. "That's... a lot better than I thought it would be..." he remarked with amazement.

The nurse chuckled, giving a little prideful smirk. "Well, I try. Anyway, I think we're finished for today. Come back in a week or two, and we'll get the stitches removed. Oh..." she passed him a little paper folder from her desk, "Give this to the receptionist on your way out."

Diamond took the folder under his foreleg, retrieving his scarf from the rack before pushing through the door. "Uhm... Thank you..." he called to the nurse, who simply nodded in reply, as Diamond left the surgery and returned down the corridor to the lobby. An hour ago it would've seemed crazy to thank the pony that had just gelded him, but if Nurse Redheart hadn't been so caring and professional, the procedure would've been a lot more uncomfortable than it already was.

Plus, his last ever sexual fantasy had been of her sucking him off... He cringed at his own lack of self-control, silently thanking Celestia that ponies couldn't read minds.

He returned to the receptionist's desk, passing over the folder as instructed. She floated it up, skimming over the pages, before giving it to a second mare passing behind her. "Another gelding - could you update its records?"

It. Diamond would have a hard time getting used to that.

The second mare nodded, "Of course," before glancing in Diamond's direction, the slow dawning of recognition on her face. Blue coat, fluffy dark-blue mane, airy, high-pitched voice... Diamond felt very, very hot all of a sudden. "I-I, uhm... I'll get on that right away...!"

"You do that," the receptionist replied impassively. Diamond didn't need another cue. He immediately turned to leave the clinic, moving as quickly as he could without seeming suspicious, giving a final sigh of relief once he felt the cool autumn air outside.

"Yo, DD!" He turned his head to the sound of a familiar voice: a charcoal pegasus, grinning from beneath his silver-blue crest. "Heard you like getting your balls cut off!"
