In my (pre pandemic) experience, FN thigh girls were NOT allowed to massage to completion, even in the VIP rooms. In fact my masseuse made sure I wasn't carrying any cash into the room and said she could get fired if I tipped her

The whole point was to edge you mercilessly, not let you cum, and then you pick a girl for the main event and quickly blast off

Obviously, things have changed and as always, past performance is no guarantee for future results.
