Jaden was walking home from the store, when he spotted a medallion lying in the grass. "What's this?" he said. Picking it up, he tried to read it but the symbols were all written in a mysterious language. Shrugging, he placed it in his pocket.
Arriving home, Jaden tossed the medallion in his underwear and socks drawer to hide from his mom. He quickly stripped down and hopped in the shower, eager to clean off from the day.
Toweling off from the shower, Jaden didn't bother putting on all his clothes, instead opting for briefs and some basketball shorts. As he took his clothes out of the drawer, the medallion gleamed brightly.
He jumped on the couch and turned on the TV, looking for something to watch. As he did, he felt a small tingle run through his groin. He wrote it off as an electric shock. Jaden pulled out his phone and started browsing his social media.
There it was again! Jaden felt a tingle in his groin again. Annoyed he put down his phone and looked down. Nothing seemed different, although the fabric seemed to be bunching up in a way that made his cock look bigger. Weird, he thought.
Just as Jaden was about to look away, he felt the tingle again! This time he actually saw the outline of his cock shudder a bit, and then inflate just a bit larger. "What..." he whispered, looking at his shorts intently. There was a definite bulge where there hadn't been one before! Suddenly, another tingle, and Jaden's bulge seemed to grow even more, inflating outwards yet again.
Jaden carefully pulled down his shorts. His briefs, which had previously been very loose, were now tighter, the pouch stretching outwards to accommodate a larger endowment, even though Jaden didn't have a very large...
Another tingle felt. This time Jaden actually saw his cock inflate through the fabric of the briefs, pressing the pouch out even more. He couldn't stand it. Jaden pulled the waistband of his briefs back to see if it was real. Nestled inside the pouch was indeed his cock and balls, but they were much larger. Jaden guessed around six inches soft and balls approaching the size of eggs.
Another tingle! Jaden saw his cock pump up, almost like an erection, but remaining completely soft. He also saw his balls inflate just a little bit. Quickly Jaden reached in to rearrange his cock and balls into a more comfortable position. Then he put the briefs back on and saw that the bulge was even bigger now. The briefs were starting to stretch to contain Jaden's new cock.
"Jaden! You here?" Jaden heard his mom calling. Quickly he pulled his shorts up and covered his crotch with a blanket. Just as soon as he did, his mom entered the room.
"Jaden, what are you up to?" she asked pointedly.
"Nothing mom". Jaden felt his cock tingle again.
"Uh huh suuuuure" she replied after a few seconds.
"What's for dinner?" he asked, hoping she would leave so he could have some alone time with his new tool.
"Pasta" she looked at him suspiciously. Jaden felt another tingle.
"Sounds great, I'll be out then" Jaden said firmly to get her to leave.
His mom looked around for a few more moments, then sighed. "Alright, be out then" and she closed the door just as Jaden felt another tingle. Thinking it was safe to remove the blanket, he did so and...
"Holy shit" Jaden's mouth fell open. The three tingles had grown Jaden's cock from huge to monstrous. The head of Jaden's enormous cock was actually showing through the shorts, and they were loose shorts! Jaden was nervous now, he didn't know how big he was going to grow...
As if on cue, another tingle was felt and Jaden saw his cock once again inflate just that extra bit longer and thicker. He whimpered a bit.
Another tingle. Another growth spurt. Jaden had to do something. He quickly pulled off his shorts and briefs. Out tumbled Jaden's monstrous cock. It hung low and heavy, but otherwise almost identical to his previous cock. Trembling, Jaden held a ruler next to it. His monstrous tool measured ten thick inches completely soft. He didn't even know what it would do hard. Jaden noticed his balls had also undergone a change. No longer the size of grapes, they now resembled tennis balls. Maybe even bigger, Jaden shuddered.
