Show off a bit.

Caleb was still standing next to Mack, who happened to be seated at about eye-level with Caleb's bulging mound.

Could be fun to put this idiot jock-bro in his place, he thought to himself. Then, pretending not to hear Mack's comment, he reached into his sweats and adjusted his cock.

"Huh?" he asked, innocently.

Mack repeated his question, "Bro, how big is your dick, dude. You're bulging like an elephant stuck in yoga pants."

But Caleb didn't hear Mack--this time for real. He was too shocked by how huge his own soft cock felt in his hands. Oh God, I'm bigger now soft than I've ever been hard. Almost as if in answer to the thought, his cock and balls swelled slightly bigger. Fuck! This is hot. Did I just grow?

Caleb hadn't caught on yet, but whatever sex god he'd accidentally invoked was listening to his every prayer. Maybe this divine presence didn't know that humans used the word "God" as an expletive these days... or maybe he did and just didn't care. Either way, the deity was rewarding Caleb for every little prayer, conscious or not, training him for discipleship.

Caleb sat down, quickly. The feeling of growth was too hot, and he didn't want to get boned up during Mack's tutoring session.

"Come on, Bro... How big are you?"

"Oh, just a little over average is all. These pants just bunch up."

"Nah bro, that's some straight up lies."

"I swear to God, Mack. Perfectly avera--" Mack gulped. His cock and balls lurched even bigger.They pushed out against the pouch and held the fabric away from his thighs. By now the length of his cock had grown enough that it just couldn't be contained, and the tip of his thick rod slipped out through the gap, the weight of it pulling his cock free while his balls remained trapped.

Mack was watching, and he saw the outline of Caleb's dong as it flopped to the side and at least nine inches of flaccid, fleshy man-meat pressed down against the fabric of Caleb's sweatpants. "Holy balls, Caleb. You getting a hardon right here in the library?"

Caleb was getting warm. A drop of sweat ran down his side. "Uh, no. Mack, I'm still totally soft."

"No way!" Mack reached his hand forward and grabbed Caleb's dick, giving it a squeeze. "Shit."

He paused, looking silently into the Caleb's eyes. It seemed like Mack wanted to speak, but then he leaned away with only a quick glance back down at Caleb's stuffed crotch. "Well, uh... I guess your daddy gave you a dick for the ages. But don't get any ideas, bro. I'm straight as they come."

Caleb sighed. "Oh, my dad's got a needle dick. I didn't get this from him." He paused, thinking. "I'm pretty sure this cock is a gift to me from God."

"You are fucking blessed, my man. Fucking blessed."

Caleb smirked, nodding.

"Amen."
