Haha I had that with my oldest friend group from back then. We are all from the same small town, and having been with a couple of girls, playing football and undressing with the other guys, and going to the local town gym, rumours of my unusually big cock got around the girls at our age. That of course made it quite easy for me to pick up girls. You know the old saying of when you step into a room, and your cock has already been there for 5 minutes?
Anyways, so whenever we'd go to private partys and stuff my friends and I would always look at who was coming at like facebook or something, I would then pick out a couple of girls i'd be interested in, so the other guys would stir clear of them. They all knew they had no chance against my 9 girthy inches.
