C or D natural at a spa is indeed a rarity. Nabi Spa had a lady named 'Phebe' who is a 'C', but enhanced. Albeit, the job is 'spectacular', as they look and feel incredible. Plus she is incredibly gorgeous. Only got to visit her once, and I hope she returns. I call weekly asking about her, hoping the mamasan passes on her 'numerous requests' to get her back there.
