Like a tittie wank, but with
arse, better with lots of lube.
First dates back to Ancient
China, ~1200 BC
The "Diang Wong" dynasty were the first to discove
rand learn the ways of the Chinese Arse Wank. Most of the masterful knowledge of the chinese arsewank was lost in the great antiquity, however the legend and myth lives on and people still attempt to practice.
