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.
