Looks like he's been cock pumping. I have tried pumping and it makes my flaccid cock go huge...around 9 inches flaccid, but its difficult to get hard straight after doing it, so its no use, so I don't bother with it anymore.
reminded me of john holmes on cocaine. sure it's big, but way too big. he has girlfriend - rosey palms, his right hand. feel sorry for the dude. this stuff looks good on video, but in real life it's a problem. where are the women ??
