I find it odd that a FS shop would be advertising massage. The main reason a customer goes to a FS shop is to have sex and to a RNT shop for massage even though part 3 may be offered by the girl at the RNT place.
Just call the shop and find out if the girl gets naked from the beginning.
I saw Riley359 advertise a japanese girl as providing only body to body massage even though the other girls do FS at this shop.
