I am one of the few people on this forum to collect hundreds of forearm pictures going back many years. I put many of them on this thread
forearm size videos now at 15 pages, scroll back a few pages to see many of my posts, I even cited the Danny D ones. Yes literally I have been trying to find one for every big dick pornstar so I know this topic well and back in the day I also collected many of them on a blog.
In conclusion forearm "evidence" is not convincing evidence. Basically you only need a 7" or 7.25" cock (which is big nobody disputes that) to fill most of a small female's forearm. Also take in mind that they use deceptive angles so it looks like the whole thing is full. Chris Strokes is a master at this and J-Mac did many.
You are not bringing anything new or revolutionary to this thread. The forearm thing has been discussed here going back around 8 years or so. It's not evidence Danny D is 8.5 or 9 inches long. The asian girl in the screenshot you posted is very small. bro shes just one inch shy of the female average shes small for a guy but not a female also the forearm size is 9 inches
And here is J-Mac in the attachment who nobody puts past 7" it fills up her entire arm. The Danny D forearm pic you cited does not prove he is 8.5 or 9.
