A month had passed, and in that time Jake had used his magical little watch and carefully-placed words to convince Josh that he was experiencing a totally made-up medical condition. Each morning, Josh met up with Jake to take his special "growth pills" that Jake swore he got in Mexico from a friend of his in the cartel. Jake had also convinced Josh to take some before/after photos to document his progress. On the initial measurement, Jake had shrunk Josh all the way down to 1.5 inches erect, and he made sure to wear gym shorts with very thin fabric to show off his own soft 7 inches (he'd cranked himself up to 11 inches erect), and he could tell Josh had noticed the intimidating monster every time.
Over time, Jake had Josh on a strict (and absolutely bonkers) workout and diet plan. Josh barely slept, he was not eating nearly enough, and was spending every morning (sometimes for several hours) repeating the same mantra: "I am more than my inch. I am more than my inch. I am..."
Josh also started wearing a prosthetic dick at Jake's suggestion "to help him with his balance" and cut off all sexual activity (even masturbation) "to maximize testosterone retention." The steroids he started taking helped him a little with his confidence when he looked at his shredded body, but itself was a double-edged sword. His balls shriveled more and his huge muscles made his already-tiny cock look absolutely minuscule.
Once Josh had bought in hook, line, and sinker, Jake started adjusting Josh's dick gradually, warning Josh to not stray from the regimen until the dosage and program was complete, and he showed Josh some pictures (helped by photoshop) of guys who stopped early and now had tiny dicks that looked like deflated balloons. Whenever Josh asked Jake about why he couldn't find anything on the internet about this disease, Jake simply responded with: "oh, hey, if you want, you can be the first guy to post on the internet about how you shrunk your own penis and have a tiny, unfuckable dick. Should I include your name and address in the post, too? Let's make sure to get your face in the shot." Josh, already made timid by Jake's presence, didn't push back and didn't dare to stop and question him.
Jake eventually let Josh grow all the way up to his old 8 inches, and then even a little further. On that day, which also "happened" to be the last dosage day, he shrunk his own cock down to a meager 6 inches, and in the cold morning wind, his flaccid size was probably closer to 3 inches than he'd like. He'd gradually reduced his own size every other day, making Josh slowly re-calibrate his own estimation of Jake's size.
"Congrats, man! You're almost done!"
"Almost? What do you mean? I've taken all the pills!"
"Yeah, but you still need to wait until those pills are completely out of your system before you even think about touching little Josh."
"LITTLE Josh? I think you might want to reconsider who's the little one here!" Josh punctuated this by smirking and looking straight down at Jake's mini-bulge.
"Oh yeah, hot shot? You think you're the Big Man all of a sudden?"
"I KNOW so. I remember the first results. You were barely 7 inches, and now I'm back to my original 8.5"
Jake couldn't help but laugh at that bit of exaggeration, which only made Josh more furious. Those steroids really made him touchy these days. Or maybe it was the sleep deprivation? Either way, Josh was one snide comment away from smashing Jake into the pavement.
"I tell you what: if you really think you're the bigger man all of a sudden, then put your money where your mouth is."
"Alright, fine! Let's measure YOU then!"
"No-no-no! Your body hasn't reached its point of penile homeostasis."
"My what?"
"The pills are still making your dick change size. I don't want to beat you now and have you whine about having grown more in a couple days. Besides, we need impartial judges, like last time."
Josh's eyes lit up at the mere idea of a woman touching his cock again. And his mind raced with the thought of the winner's spoils.
"Ok! Yeah! So what if we have Katie and Liz measure us again, but this time let's raise the stakes."
"Oh yea? What did you have in mind?" Jake asked, trying to hide his glee. This was all working out too well.
"This time, loser has to watch the winner fuck his girlfriend."
"I don't know if I could convince Katie of something like that..." Jake hedged.
"What, are you scared of Katie getting fucked by a real man?"
"How about this: we set up a double date at my place this Friday, and we pitch the contest to Katie and Liz then. If they go for it, we do it, but I don't want to fuck someone if it upsets Katie, and I certainly don't want to force myself onto Liz if she wants to remain faithful to her *little* man."
Jake realized that he had delivered one insult too many as Josh's fist sent him hurtling to the ground.
"I'll be there, asshole. And I will fucking obliterate you on Friday."
"You know," Jake thought, "aside from all this blood in my mouth and this knot on my head, this went perfectly."
