“Dustin!” Ty hissed from across the store.
Dustin looked over at him from his position near the counter. “What?” he playfully mouthed.
Ty frantically waved him over. Dustin tolled his eyes, but complied and strolled over to a private spot behind one of the clothing racks.
“What is it Ty?” Dustin asked in a disinterested manner. “I’m actually starting to have a bit of fun for once.”
“That’s the problem!” Ty complained. “I think you’re having a bit too much fun!” He gestured down to Dustin’s bike shorts, where an sizable cock was snaking down his leg, accompanied by two swollen balls. It looked like Dustin had shoved a sausage in his shorts. “If you keep this up, you’re going to have trouble walking soon with that thing weighing you down!”
Dustin groaned. “It’s not that I’m gay or anything, it’s just that seeing those guys grow is making me think about my own dick, and you know how it goes from there. But I guess you do have a point. Why don’t you just undo it?”
Ty sighed in frustration. “That’s what I’ve been trying to do! But I think because I said you would have to do this all afternoon, it’s stuck like that for a while! It was fun at first, but it’s starting to become a problem.”
Dustin groaned again. “Well shit. What am I supposed to do, not think about my dick? That’s a lot easier said than done.” They both sighed. “At least my muscles aren’t growing too or something like that.”
“I wish they would,” Ty complained off-handedly.
Suddenly, Dustin felt something shift in him. “Oh shit!” he moaned. “I think you just made that happen!”
“What!? Oh no...” Ty worried. “Try not to think about your dick or anything like that! That’s the only way to keep it from happening!” he hissed.
“Really Ty!?” Dustin yelled. “Now that’s all I’m gonna think about!”
Dustin groaned as his muscles and cock swelled under his already tight clothes.
“Ahhh! he yelled. “Do something Ty!” He moaned as his body grew outwards once more.
“I can’t!” Ty screamed. They were beginning to draw a large crowd from their rising voices.
“Oh fuck!” Dustin groaned as he ran out of store. “I’ve got to get out of here!”
“Dustin, wait!” Ty called after him, but he was already gone.
Dustin ran through the mall, trying to ignore the faces turning to watch as his clothes straining under rapidly swelling muscles and a once-again growing dick. He could hear the fabric protesting as his once small pecs, arms, and quads began to force their way outward. He continued to run in search of some form of privacy.
“Stop thinking about it.. stop thinking about it...” he thought to no avail as he grew hornier and continued to grow. “There!” he thought. “A bathroom!” He pushes his way inside the thankfully empty room and quickly locked himself in a stall. Sitting down on the toilet, he closed his eyes and tried to concentrate.
“Stop thinking about it... stop thinking about it... stop thinking about your massive cock and huge muscles ooooOOOOH.” he moaned as his thoughts triggered another strong wave of growth that radiated throughout his larger body. He winced as he felt seams began to give way under his swelling body and tears began to appear, showing the growing muscles beneath. “I’m gonna fucking kill Ty when this is over...” he growled to himself, pressing hands against the walls of the stall in an effort to stop himself from growing, which was proven futile by the sounds of fabric wrenching and shredding.
He groaned in pain, pleasure, and probably a bit of fear as his near-footlong cock finally peeked out the bottom of his too-small biking shorts and his now orange-sized balls fought for space. The sound of tearing fabric only made him hornier as his swelling pecs began to split open the front of his t-shirt, now covered with a light layer of brown hair from the rapidly increasing levels of testosterone in his quickly-growing body. He looked in horror as his shoulders and biceps approached the size of grapefruits, shredding the arms of his now-tiny t-shirt.
“No...” he moaned in futile protest as his thoughts continued to escalate his growth like a feedback loop of horniness. “I have to stop... aaaAAAH!” he yelled as a loud shredding noise signaled to him that his t-shirt had been split down the middle and fell in tatters. He looked down in horror at the new, enormous, and slightly hairy muscles of his chest, arms, and incredibly defined abs. He could feel the muscles in his back swelling outwards, despite his inner attempts to stop himself from thinking of it. He looked further down amidst the sounds of protesting fabric at his bike shorts, somehow still on but practically strangling his big quads and thick, weapon-sized cock.
“Shit, I could fucking impale someone with that thing,” he chuckled to himself, but it was cut short as that thought triggered a new and rather strong wave of growth.
“Oh no... oh no..” he moaned as he felt something building deep inside of him, radiating outwards. His muscles grew outwards once more, gaining unholy amounts of strength for a teenager. “Oh.. oh... oh FUCK!” he screamed and arched his back in incredible pleasure as the wave reached his massive monster of a dick. Everything seemed to stop for a moment, and then his cock ballooned outwards and finally blasted through the paper-thin fabric of his shorts, ripping them from his godly body.
Dustin sighed in relief, but quickly realized in horror that he was still growing, since he was still horny. He looked down with wide eyes as his increasingly hairy pecs pushed out a little more, his abs tightened a little more, his arms thickened a little more, and his now rock-hard cock stretched out a little further. He blushed slightly as he felt himself rise up a bit, probably from his thickening glutes. Increasingly panicked at his large predicament, he desperately thought to himself. “How the hell can I stop thinking!?” After a moment, his eyes widening in relief and he slightly smiled, before slamming his head into the wall, knocking himself out cold.
From his buck-naked seat on the toilet, his bodily growth finally slowed to a halt, leaving the unconscious god of a teenager to be found by his brother.
