Story to an illustration: Cheer goes to the urologist for the first time after mustering enough courage to show his impressive-sized junk. Shenanigans enuse as both try to ignore the lust and raging boners.

“So,” Lavender Care said. He hefted his clipboard, squinted down at his messy handwriitng. “Says here the last time you had a checkup was...two years ago?”

The massive stallion sitting on his examination table nodded. “Yes,” he said, his deep voice surprisingly gentle. “Sounds about right.”

“Mm.” Lavender tapped his pen against his chin. “Okay, then. Just means we’ll have to be a bit more thorough, then. Would you mind removing your clothes for me?”

“Oh! Uh, sure.” Lavender glanced up. Wind Cheer was blushing lightly. The doctor sighed internally; there was always a patient who felt that their checkup was a bit more personal than they’d like. It didn’t help to reassure them that he was a professional, that he was here for their health, and not as any sort of pervert or voyeur. He watched with an admittedly clinical interest as Wind Cheer first removed the baggy sweatshirt he’d worn on the way in, an eyebrow curving up as he saw how thin the stallion’s shirt had been stretched over his body. His muscles had stretched the fabric until its threads did little more than hug every curve of his body, emphasizing just how big, just how bulky, the massive stallion really was.

Then Cheer began to remove the shirt as well. Had he been off the clock, Lavender may well have let out a whistle. Cheer’s upper body simply bulged with muscle: full, rounded pecs; thick, bulging biceps; and a six-pack that looked like it had been cut from steel. Had he been a lesser stallion, the doctor would’ve been jealous; four years of workouts had left him with a swimmer’s build, which, while certainly appreciated by his more recent partners, continued to disappoint him with its comparative skinniness. Here was a body, though, the swelled with power, bulged with strength, built like a steam train and—

He cut that line of thought off halfway. Couldn’t get unprofessional, now. A low cough cut off the blush that had started to rise from his cheeks. But as Cheer began to remove his baggy pants as well, the blush returned in full force.

Bit by bit, the pants slid down, revealing a pair of boxer-briefs that had been stretched beyond all reasonable imagination. Lavender’s hand quivered as he watched Cheer’s enormous bulge come into view: a massive, obscene mound in his underpants that had to be more than twice the size of his head. Just from here, he could easily make out a massive sphere protruding from the larger stallion’s crotch, nestled gently above two smaller bulges (which were still quite enormous in their own right). Lavender gulped and clicked his pen a few times, a nervous tic he’d picked up in medical school, as he watched that enormous bulge rise and fall gently with Cheer’s breaths. Suddenly, it didn’t seem so strange to him that the stallion had walked in here wearing such loose clothing.

As Cheer made to remove the boxer-briefs (though some part of Lavender’s mind wondered how he planned to get them around that bulge, let alone how he’d even gotten them on), the doctor blurted, “That’s fine, that’s fine. You can leave those on.” He licked his lips as Cheer turned his big, curious eyes down onto him. Even seated on the examination table, the muscular stallion was still a head taller than him. “I, er, we’ll be doing a minimal examination today.”

“Sure,” Cheer said. He let his hands fall onto his lap, then blushed when he realized that his “lap” consisted of his bulge, and that his resting palms were doing little more than caressing his concealed stallionhood. He quickly moved them to the table instead.

“Ah.” Lavender cleared his throat. “Er. I’ll need to be able to access the entirety of your, ah, equipment. So if you could stand for me, please?” He licked his lips, struggling to hold onto his professional outlook. With that massive bulge filling his vision, though, that was becoming more difficult by the second.

Cheer nodded and heaved himself off of the table. His package bounced a little bit from the impact, small vibrations rippling all across the fabric. The doctor nodded to himself, stepped forward...and instantly felt Cheer looming over him.

At six feet even, he certainly wasn’t a short stallion. But beside a stallion who easily hit eight feet in height, and with arms that looked to be as wide as his entire torso, he suddenly felt very, very small. He swallowed again. He wasn’t sure if he liked that or not. With trembling hands, he reached out and took hold of Cheer’s package.

Even through the fabric, Lavender could feel the warmth of Wind Cheer’s stallionhood. He could feel the slightly damp fabric slide against his palms, could feel the blood thumping against his skin. He hefted it in his grasp and inhaled sharply; this was heavy. It had to weight a good twenty pounds, at least! How in the world…?

He pushed the thought out of his mind. He had to cling to his last scraps of professionalism somehow. Licking his lips, he let his hands slide across Cheer’s package, ostensibly checking for any bumps, lumps, or other irregularities.

But his patient seemed to have fewer compunctions about professionalism. Or at least his biology did. As Lavender’s comparatively tiny hands roamed its surface, Cheer’s stallionhood began to stiffen, swelling, straining against its fabric prison. Cheer squeezed his eyes shut and bit his lip. He couldn’t get a boner. Not here, not now.

“W-well,” Lavender said. “You seem to be quite healthy thus far.” He wasn’t blind; he could see Cheer’s stallionhood growing before his very eyes, and could feel it growing stiffer beneath his touch. Maybe he could finish this checkup a little more quickly than usual; it wasn’t odd for a patient to get a boner during examination, but somehow he felt that such an occurence now would be...compromising.

He bit his lip, and mentally swore at himself when he realized that his own crotch was feeling particularly tight. He didn’t have to look down to know that he likely had a fairly noticeable tent in his own pants by now. Cheer’s package may have been absolutely massive, likely reaching a foot and a half in diameter while still soft—How? a more medical, scientific part of his mind shrieked; How was it even possible to be this large?—but Lavender’s ten-incher was big enough on its own to be easily noticeable whenever he got a boner in public. Usually, he had the chance to tuck it under his waistband, or press it down against his leg...but standing here, hefting Cheer’s enormous package in his hands, he somehow felt that it might be best not to draw any attention to his own growing arousal.

Professionalism. Right. A plastic smile all but stapled across his face, Lavender finished his inspection—checking the space between the penis and the testicles (he hoped that using the scientific words would help; it didn’t) for any problems—and finally, thankfully, let Cheer’s package drop back down to his muscular thighs. He let out a breath he hadn’t realized he’d been holding, picked up his clipboard, and buried his nose in it.

“All done,” he said quickly. “You’re in tip-top condition.”

Wind Cheer blinked down at him. “You sure? That’s all?”

“Yes, yes,” Lavender said, coughing. “Very good. You’re free to get dressed.” He waved a hand dismissively and turned away to the countertop. He took the chance to readjust his throbbing boner, wincing slightly when he felt a damp spot on the front of his pants. Dammit. Dammit, dammit, dammit.

“The nurse will take a urine sample,” he said, trying to keep his thoughts clear. But the idea kept coming back: an urge, an inescapable curiosity that went beyond just the academic. “And we’ll take a few more notes, and you’ll be free to go.” He suddenly imagined Cheer strolling out of the office, not in his originally baggy clothes, but just in his underpants, his monstrous bulge swaying gently from side to side with each lengthy step—

Oh, for fuck’s sake.

Lavender spun back around on his heel. Cheer was around half-clothed now, but the top of his bulging chest still more than caught the eye. The larger stallion blinked down at the smaller, noting that the doctor was blushing madly.

“If you’d like, ah, a more thorough examination, though” Lavender said quickly. “I get off at six.”

The door slammed behind him before Cheer even had the chance to process his words.
