This is a big cock, but not as big as this picture is showing.
Sorry but it is definitely not real. In fact, it is not a good rendering. If you enlarge the picture or even just look close, you will see that just above the dark area one hand up (yep, big cock anyway), it changes color. This is the added area.
In the enlarged ( :blink: really, no pun intended), version you can see the real cock head and then the added cock head.
Hey, a two-headed cock! Maybe we should contact the Guiness Book of Records?
