He agrees

He gives you one last look as if to test your sincerity but finally relents. Wordlessly, he motions for both of you to move towards the clearing behind the bushes.

Once there, he drops his pants and boxers, revealing his flaccid penis, which was definitely much smaller than your own.

"So, how long does it get when you're hard?" you ask, "It looks to be around two inches soft"

"It grows to around five to six inches hard," he replies, "But, I've always been to afraid to measure if accurately so I don't know which way it swings."

"What's your phone?" you ask, an idea suddenly forming in your mind.

"An Iphone 6S, why?"

"Give me your phone and get yourself hard," you command him, "Let's settle this now before you go in."

"You're not planning on taking a video of me now, are you?"

"Get yourself hard," you repeat yourself.

He stares you down for a second but his confidence wavers and he hands you his phone before moving his left hand downwards to his cock.

He strokes himself and you wonder what he thinks about as he does it. You see him start to chub up. He must have an exhibitionist kink to be able to get hard so quickly in public. A few strokes later, precum starts to form at the tip, indicating that he was now fully hard.

You move towards him with his phone in hand and kneel in front of his erect cock.

"Wh-what are you doing?"

"Measuring your dick," you announce as you swat his hand away.

You grab his erect dick in your hand and are mildly amused by how small it was compared to your own. You line up his iPhone against his cock and compare the lengths. His cock is slightly longer than the phone.

Satisfied with what you've discovered, you stand up and give him your most mischievous of smiles.

"So?" he asks, his voice laden with anxiety.
