and what is the story behind it?

In my driving class there was a guy who probably went without underwear and had a really big flaccid dick running down his leg

He was wearing a gray sweatshirt, and his dick was thick even when flaccid

I was at a time in my life where I would hide any bulge I had as much as possible and even though I knew I could be bigger than him, seeing women's reactions excited me a lot.

I heard women commenting and making jokes about, "like three legs" "imagine when he's erect" "that thing is a weapon"

and the coolest thing was a woman saying in a group of people I was part of "when he walks that thing hits his leg, it's impossible not to look"
