Nyotai Mori is a sexual performance to serve food like sashimi on female's naked body in Japan. Outside Japan, it is used for sweets like chocolate, cream, or fruits. Some brothel like "Sphinx" in France used to serve caviar on female's body. It is still carried out in some spas or show pubs.
There's a mention about customers who bothered doing nyotai mori in a text book for yuujo prostitute in Edo era "Osakame Maijou". However, this kind of act was not welcomed in prostitution, so when it's reported, bouncers were called to stop it immediately.
