After a few seconds to get over the shock of what Frank was suggesting and a few more to wait to see who would be the first to rise to the challenge, Jason rose and thrust his hips out, jutting his cock for his friends to see for the first time. 5.5 inches long, cut and completely shaven, Jason's dick had no curve to it. It personified the idea of a flagpole. His low hanging balls had a few golden wisps on them, but for the most part, they were hairless too. What was really remarkable was that there was already a drop of precum forming at the tip.
Frank stood next in front of Jason and held both cocks in his hand. Frank's was clearly wider and was longer too by a good inch. Frank's pubic hair was neatly shaven, save for his treasure trail and a square patch around the base. His balls were a bit on the smaller side but swung like a pendulum between his legs.
Jason inadvertently moaned when Frank's surprisingly soft hands gripped his dick. He hated the feeling of them leaving as Frank turned to the rest of the group to ask who was next.
Percy stood, being the oldest (not including the fact that Nico was born first). His cock was curved to the left, a solid 7 inches long, but not incredibly girthy. His bush was clearly trimmed here and there, but for the most part it was kept as it naturally grew. He had a large vein going from the base and wrapping around to the underside of his mushroom tip. Frank and Jason crossed over to physically compare and Percy couldn't help but enjoy himself as they touched him. It was all he could do not to cum then and there.
Nico showed himself off next. Although he had been uncircumcised as a young man in Italy, he went through with the procedure once he had been rescued from the Lotus hotel. His surgical scar was still clearly visible. Nico's cock was very excited to be able to show itself off. A beautiful specimen, it was just a hair longer than Jason's and definitely thicker than Percy's. His balls were clean shaven, but his pubic hair was on full display. It definitely looked like it had been shaved recently but was now starting to grow back. While being physically inspected, he hung his head back in ecstasy when he felt their hands traveling down his taut stomach.
Finally, they all turned to Leo who beat them all to the punch. He crossed over to them and took their cocks in his hands to compare. Leo's pubic was untamed. It grew wildy, almost concealing a good inch of his base. That didn't bother Leo as he was confident he had enough length to spare. A good 6 inches long, Leo's dick curved up as if to say hello to its master. His balls didn't hang very low, but were a good size, probably about the size of golf balls. Thicker than Nico's, Leo's penis was his prized possession and best friend. Leo enjoyed taking charge in being the one to measure against his friends. He felt like a leader being able to control them like that and subtly making them quietly moan when he "accidentally" started stroking them.
"So now what?", Jason asked, mildly miffed that he was the shortest, although not the skinniest. That honor belonged to Percy.
"Now-," Frank started.
"Now, we have some fun". Nico finished.
