Dark meets LD for a physical...
by Dashiel (with a little help from the artist:)
Dark waited in the office, nervously. The higher-ups had called for some sort of physical exam, and of course that meant everypony had to get poked and prodded. He fluttered his wings shyly as several uniformed ponies filed in and several more uniformed ponies filed out of the waiting room. He didn't really like exposing himself around other stallions, they tended to stare.
Dark was big, even for a palomino, and the rest of the nurses had told him to wait for a specially trained nurse better able to cope with ponies his size. He felt quite conspicuous as many others were seen to first, and hid behind his chestnut mane.
Finally, a piebald nurse with a long black mane trotted into the examination room and walked around him appraisingly. "Oh, yes, I think you're the one," she said to him. "Please put your flank through the privacy screen and we'll begin."
"Yes Ma'am," replied Dark, nickering in surprise as she unbuttoned his pants and pulled them down.
"Ooh, you are a big boy, aren't you?" whispered the nurse, just loud enough for only Dark to hear. "I bet all the stallions are jealous of these foal-makers."
Dark rustled his wings nervously, he didn't know what to say. He let out a small whinny as he felt her silky smooth fetlocks play over his crotch and her hooves gently play with his heavy balls. He blushed as he saw other ponies look his way, and tried to grin. Soon enough they looked away, and he tried to get a glance behind the curtain.
The nurse waggled a hoof at him. "Uh-uh, no peeking! Relax, big boy. I just need to take some... special tests," said the nurse, bending her muzzle closer to his sheath. Dark couldn't help it as his cock extended due to her tender ministrations. He froze in shock as he felt her tongue flick against his shaft, playing up and down it until she finally took the whole head in her jaws and bobbed her head back and forth, inching slowly further and further along as she expertly sucked at his length.
Dark's muzzle was stuck in a shocked expression as, hidden behind the screen, the lusty gypsy vanner gave him the best blowjob he had ever had. He daren't move; if he tried to, all anyone would see would be a sergeant with his pants around his fetlocks and a huge erection to match his already-oversized, meaty testicles, all flapping freely in all their glory.
Gradually he relaxed, as the pegasus felt both hooves of the nurse begin to actively massage his balls. Trying not to attract attention, he spread his legs and raised his tail as he fought to both enjoy and hide the emotion surging through his body.
Suckling relentlessly, the nurse expertly brought him to shuddering climax. He almost cried out as his hips thrust forwards; there had been a sharp pain as the nurse had pinched his balls at the exact same moment as he'd unleashed the hot torrent of seed deep into the greedy mouth of the black and white mare.
LD sighed happily as she pulled the syringe out, emptied of its contents much as the stallion's balls now were. She swallowed slowly, licking her lips to make sure she'd caught all of his seed.
"Just two more things, Sergeant," said LD, slapping the pony on his balls. When he didn't overly react, she knew the anesthetic was working.
Taking hold of the beautiful foal-making equipment of the stallion, she savoured them a short while. She played with them, rolling them and tugging on them, kissing them. Sergeant Dark could feel her doing something back there, but he didn't know what. It felt good though, whatever it was.
LD was enjoying herself. The velvety smooth scrotal sack was thin, just the finest of layers between her and her prizes. Tugging on both the heavy balls, she drew the skin taut, pulling on them for a better view and easier access.
Picking up a scalpel, she made two neat slices, one on each mound. Her touch was light and deft, and the testicles within were unmarked. As she pulled, the cuts widened. Working ever so gently, she applied the scalpel a few more times as necessary. Within the stressed sack, the balls bulged outwards, pushing against the neat holes, like foals fighting to be born.
Her smile widened at this, and her heart raced. She flicked her tail, feeling the moisture at her netherlips, leaking from arousal at the glorious sight. It was all she could do not to speak to them, to coax them out verbally.
They glistened, now, as she kept up the pressure. Clear liquid dripped from the neat, precise wounds, mingling with a small amount of blood. Dabbing at the rivulets with cotton, she gasped with desire as those heavy testicles popped out, bursting through their protective sack. They hung, suspended only by their cords, glistening in the neon lighting. They were a milky white, speckled with veins of red.
"Almost ready," she whispered to Dark, voice hoarse as she beheld her treasures. Every stallion's balls were different; each pair was unique, a delicate patchwork maze of blood vessels and arteries. They were magnificent. And they were now hers.
Stapling the cords closed, high up near to the pegasus' body, she moved her attention immediately down to the subtly cooling balls. With a neat snip of some surgical scissors, she freed first one and then the other precious orb, separating it from its previous owner. Shivering in delight, she gently kissed and patted each one and placed them reverently in a silver bowl. Next she trimmed and tidied up the cords of the newly-gelded pony and then sutured the wounds on his scrotum, and all with him none the wiser.
His majestic foal-makers were hers now. It was almost a shame that nopony else would get to experience them like she would, but that made them all the more special to her. He would never again be the alpha stallion, always now second or third below the mares and the real stallions as his symbols of masculinity had been ever so neatly removed, quickly and permanently.
Fixing two small butterfly plasters on each tiny wound of his now-empty and flaccid sack, she deftly pulled his trousers back up and slapped him on the rump. "That's it, buck, you're all ready. Your tests are done, everything's perfect. Off you go now! Don't worry about it if you feel a little weird for a while 'back there', you'll get used to it."
"I, uh, do feel a little light on my hooves..." replied Dark as he stumbled awkwardly out of the room.
"I bet you do," said LD with a smile, eyes fixed on her two prizes as they lay glistening in her bowl.
