No I cant do it, I guess you would need reasonably low hanging balls. Maybe I didnt describe it very well its not really a know more like just wrapping your cock around and under your balls and then tuck the head in between the shaft and ball sack to hold it in place.
I found 1 pic on google images but it looked photoshoped.
I am sure there must be someone on this site who can do it give the size of the guys on here there must be at least one.
