I don't like to be a spoil sport, but I don't think it's a huge cock. I used to work as a commercial photographer and I can see it's shot from a good camera angle with a wideangle lens which always makes objects nearer to the lens look huge. I also think that the final video has been stretched vertically to make that cock look longer. I think the guy's cock might be above average in length. Perhaps 7" or maybe 7.5" and it's thickness is average to large - maybe 5", but it is very difficult to tell for sure without a scale of some sort in the picture beside the cock. I remember doing pictures for archieologists and museums where I had to include a ruler for scale in the picture with a vase, or axe head, etc. It was terribly difficult to make an 'honest' job of it. You only needed to position the scale a bit too near the lens and the object would shrink by an inch, or vice versa. It was safer to shoot from a long way off with a telephoto lens, but that wasn't always practical. The truth is that most guys modelling in porn shoots have average and slightly above average cocks, and there are a lot of photographers who know how to flatter them.
