The amount of dick in this scene is not for the faint of heart. Extra-thick and big Kian is taking on even thicker and bigger Ben Harington.  There is almost an intergenerational thing going on here, as Kian has been with us for many years, and Ben is still fairly new, but the dynamic works well with them. The guys don't share any common language other than a few words in English, so everything here is more instinctual and natural than scripted.
