To orally or manually stimulate the clitoris. This is inspired by the anatomy of the vagina as the clitoris is nicely situated between the labia, or in the middle of the labia. Hence the phrase.. " work the middle". We have American pop artist "Allyah" to thank for this public service announcement/song that brought so much awareness to often forgotten and ignored lady parts. The phrase was originally coined in Allyahs hit song " Rock the Boat".
