Turns out, however, that I was wrong. These long green shoots lesbian videos are actually (and probably obviously) sugarcane. The cane had been stripped and was being made into a cold drink on a pierside on Cat Ba Island in Halong Bay. The vendor fed each stalk into a motorised mangle one-by-one, collected the liquid in a jug underneath then mixed it with crushed ice in a tall glass.
The result was a white, cloudy drink with a light, sweet, refreshing taste. My loud declaration that “this stuff would go great with rum” came only slightly before I realised they were basically one and the same.
