I am an extreme pumper with a shitload of experience. If it is pumped, it is only moderately pumped... and if it is a silicone job, it is an EXCELLENT example of such an activity. There is a good chance that he is wearing a cockring or strap and I am almost POSITIVE that he is. He could just be wearing the ring and using Viagra to trap a HUGE amount of blood in his penis... it is quite red in appearance, so that could be the case.
The most disturbing thing is the scars near his nipples where he had gynocostemia (bitch tits) removed, this is MOST likely from steroid abuse in his past.
His experiences in injecting steroids could have led him to consider injecting silicone... I mean... once you are good with a needle... everything looks like it needs an injection! What is the old saying? Everything looks like a nail to a hammer? lol!
It's a HUGE cock and who gives a shit how it got that way... it's ALL GOOD!
