The dick is likely modified in some way, likely silicone injections, but he's done too much from other angles for it to be fake(especially on his OF). The video showing piss, then cum that goes from thick to watery is pretty good evidence it is real. Hyperspermia is usually very watery with a low sperm count and high risk of prostate cancer. It is not the attractive massive loads that are in this thread, but it is cum just the same.
