I'm a new member. I think that cubic inches is the way we should describe our cocks. For example I am just average in length. 5 inches. Just average in girth. 4.75 inches. But the cubic inches is just 9! This means that if she were lucky enough to be fucked by a BBC with a length of 7.5 inches and a girth of 5.5 inches then she wouldn't just have 50% more cock but a fantastic doubling. Twice as much.
