There seems to be an agenda to underestimate Vlad here, who has arguably the largest overall cock in porn history. Take a look at when Mia Martinez mounts him from 16:30 - 23:00 in this video:

That an EXTREMELY THICK (in addition to long) dick struggling to squeeze into her tight pussy. One of the hottest, most epic initial penetrations I've ever seen. 6 inch girth??? LOL, I don't think so. His cock seriously looks thicker than her UPPER ARM here:

He is clearly MUCH thicker than Shane Diesel. Probably even thicker than Shorty Mac. I think maybe it's his tremendous length that throws it off a bit visually, giving the impression of a thinner cock. A shorter cock will naturally look thicker and a longer one will look thinner. But make no mistake, Vlad is at the very top in terms of thickness. Quite possibly the thickest of all. If this is strictly a result of pumping, then I'm surprised it's not standard for all porn stars (although it's rumored Shane pumps as well).
