Diego watched from the exam table as the door opened. He was met with a wall of white labcoat fabric, but after a moment Diego realized it was only the arm and shoulder of the figure that took up almost the whole doorframe. Diego felt a pang of jealousy at the sight of someone bigger than him, but he could also feel his prodigious cock start to strain his pants, making the tight fit even tighter. The behemoth stooped down to get his head under the doorframe, revealing the face of Dr. Andrews who was awkwardly sidestepping through the door, trying simultaneously to not hit his head on the top of it and not get stuck inside of it. He moved with a certain clumsiness that seemed out of place with such an immense frame. It was a clumsiness Diego himself was familiar with, having had the experience of needing to get used to an entirely new body himself just a few months ago. He smirked to himself, silently feeling thankful that he was past the stage of constantly knocking things over and bumping into things with his shoulders. Though he wouldn't mind another round of freaky growth, the mused. He was shaken from his thoughts and gasped as Dr. Andrews turned to face him though.
Diego felt a heavy shot of precum fire from his uncomfortably hard dick as soon as he saw Dr. Andrews. Dr. Andrews's size was beyond words. It was no wonder he came in through the door sideways. He was at least twice as wide as the door, and his head almost reached the celling. He practically took up the entire wall of the small exam room. He might've looked just as freaky as Diego's nearly 275 lbs of prime beef, but Dr. Andrews wasn't 5'4" like Diego. Diego guessed he was pushing 7', if not surpassing it, and his greater height made him look like an absolute monster. Dr. Andrews looked like someone took Diego and scaled his entire body up. The top two buttons of his labcoat were undone, likely not by choice but because labcoats weren't made with doctors who have shoulders the size of semi trucks in mind. Dr Andrews's open labcoat revealed the top of his pecs which could've met with his chin if they wanted to. The remaining buttons were pulled to the point of gapping even across his stomach which bowed out, round and hard, each abdominal muscle visible as they pressed against the tight material. Dr. Andrews uncomfortably shifted his weight, still not used to having to keep his stance wider to make room for his legs, which flared out dramatically, almost sphere-like so great were their width before tapering back into his knees and blowing up again at his diamond-like calves.
There was probably another reason he looked uncomfortable though, Diego thought as he noticed a large bulge tenting the bottom of his labcoat in the front. He couldn't tell how big the doctor had gotten, but based on his own experience, he could stake a few guesses.
Diego also felt another flare of jealousy at the thought of Dr. Andrews, who was already a tall man before, getting even taller while he hadn't gotten any taller himself. His anger and jealousy was betrayed however as his wine bottle dick released another gob of precum, even more than before.
"Diego, how have you been?" Dr. Andrews said in as professional a tone as ever. "Have you been hitting the gym despite my advice? Your charts say you weighed 258 lbs at your last visit but weighed in at 273 today."
"Yeah, I have" Diego eked out a response at length. As he looked at Dr. Andrews's face he noticed that the older man looked healthier than before. He didn't look younger, per se, but his salt and pepper hair looked thicker and his complexion looked more even while still maintaining the lines around his eyes and mouth that marked his maturity.
"Well, I can't say I expected much different. Its good to see that your growth seems to have slowed. We don't know what this condition is, so I'm glad you didn't grow another 100 pounds since our last visit." Dr. Andrews said.
"What happened to you doc?" Diego asked, barely hearing a word out of the doctor's mouth.
"The results from your *ahem* semen sample came in." Dr. Andrews continued, ignoring Diego's question. "It looks like there is some kind of viral agent present, but no other information is known right now. The fact that its viral means that it can't be cured unfortunately. I'd like to keep you under observation and bring you back for regular visits to track your health. Have you noticed anything new in the past month?"
As Dr. Andrews finished his question, he reached for a pen and notepad in the breast pocket of his labcoat. A ripping sound rang through the exam room as the shoulder seam of his labcoat ripped, revealing a striated bowling ball underneath. Dr. Andrews still struggled to reach the pocket though. It wasn't the fabric that was constricting him. No, he was simply so engorged with muscle that he no longer had full mobility. His biceps squeezed against his pecs and his forearms preventing him from bending all the way, and the more he struggled, the harder he flexed, making his immense chest and arm swell even larger and push against each other even harder.
Diego drew in a sharp breath and tried not to cum on the spot as he watched the spectacle and felt precum leak like a faucet down his leg. He instead lifted his own thickly muscle arm and lifted the pen and notebook out of Dr. Andrews's pocket and handed it to him.
"*Ahem* yes, thank you, Diego." Dr. Andrews said. A flash of embarrassment and what Diego thought might have been sexual arousal flashed across his face before he quickly regained his composure. "As I was saying, any other effects, symptoms, changes?"
"Well, I'm not growing as fast" said Diego. "I mean, I only put on 15 pounds in the past month."
"Only?" Dr. Andrews said, looking up from his notepad at Diego before returning to writing.
"Yeah, come on doc. You know how it feels to grow so fast its like you can watch yourself grow in the mirror. I loved that feeling. 15 pounds is like a drop of water in the ocean. I remember waking up every day feeling bigger, stronger. Harder. You get it now, right doc?" Diego said, flexing with one arm as he crudely palmed histhick sausage through his shorts.
"I do" Dr Andrews said raggedly as he sharply inhaled. His own contagion-enhanced cock was painfully hard in his pants. Like the rest of him, like Diego, it had also grown to monstrous proportions and his libido had grown to match. The doctor who was trying his hardest to maintain his professionalism was beginning to be overtaken by something more carnal.
"You'll have to- uh- excuse me. It seems yo- you're experiencing intense- sexual urges, Diego?" Dr Andrews asked between gasps and grunts as he desperately tried to hold himself together.
Diego at this point was too lost in his own sexual gratification to answer the question. He managed to get one hand on his prodigious cock around his pecs and muscle gut, but was busy kissing and worshipping his own vein crossed bicep.
Dr. Andrews looked on at Diego's show and felt his own hand wander to his own pendulous meat, itself even thicker than a wine bottle. In a moment of clarity, the doctor tried to stop himself and Diego.
"I *gasp* don't think this is- a- appropriate Diego. I th-think" But he was cut short as Diego erupted. Shot after shot of cum rained down, covering Dr. Andrews in his cum. Again. But this time Dr. Andrews who was teetering on the edge of orgasm came too, adding his own immense cum shots to the mix, slicking Diego in his own seed.
As the two of them came down from their orgasm, clarity dawned on them as they realized they and the exam room were all covered in cum.
"Sorry doc" Diego said between heavy breaths.
"Yes well," Dr. Andrews began, trying to regain his composure, "I suppose I have new semen samples to process now." He chuckled slightly.
"We have a chemical shower you can clean up in if you'd like" Dr. Andrews continued, as he tried to wipe some dripping cum off his forehead, but couldn't quite get his arm to reach, once again prohibited by the sheer size of his musculature. "Clearly *ahem* we've seen that this contagion can be spread via seminal fluid," Dr Armstrong said, giving the first acknowledgement of his altered physique, "but unless you and your football friends were exchanging semen, I'd assume it can be spread by close contact as well. I recommend you still avoid having sex with anyone and keep an eye on those close to you for any signs of infection. Hopefully since we've both been affected, we won't be affected by this *ahem* incident. Please alert me if anything happens."
Diego, taken aback by Dr. Andrews's quick return to business, especially given what just happened, simply nodded an affirmative and proceeded to clean himself off and head home. But what happens next?
