On the last one, about mid-way on his cock the aliasing of the image changes. It has a blur inconsistant with the rest of the image. This could be a cover up to a cloning/stamping tool found in something like Photoshop or Paint Shop.

On the third image, you see the effect again below his thumb. It works well because it is where his circumcision scar should be, but it has a very smooth and quick transition - unlike an actual scar. The texture of the veins changes here under the blur after the clone/stamp.

To me, the first one gives it away the most. Here you can easily see the duplication lines. From the bottom of his cock, look about 25% up and notice the color change. Then look about 60% up and notice the same change again. Then notice the shape of the veins and texture. It's a clone method where he's using parts of his cock to make more cock. He'll probably fool 99% of people who see the image.

But who cares, and if Veronica saw him on cam then case closed and kudos to both! Also, who cares about his cock - did you see that chair? Those things are expensive! And nice!
