So you haven't seen my report on her?
Anyway she is up for anything for the right price. You just need to negotiate beforehand what kind of services you want. She has a bag full of different sex toys, so just pick which one you fancy.
There are several bus routes to Yuen Long and there is a West Rail also. It takes around 30mins from TST and 40mins from Central so it is quite convenient.
They also make famous and tasty "old wives" cakes in YL which you can bring back to your mates.
