「Gem king with meat」: it is unlikely that even a single pearl would be wasted by tossing it in a bonfire as a sacrifice even by a lord, with pearls in the old days being the most expensive of all gem-type 'stones,' yet it may well have been applied「inside the sacrificial meat」of a concubine (only kings could afford giving strings of pearls away)…strings of pearls have been used to stimulate female sexual anatomy for a very long time, with various techniques that encompass everywhere between the anus and clitoris inclusively and simultaneously. A「meat sacrifice」was the euphemism applied to a female giving up her normal life by having her feet no-longer-integrated and instead becoming a divine hunk of meat and professional sexual services provider. PEARLS and the source of pearl used in Chinese euphemistically to represent droplets of ejaculated semen, that「small amount, 3/5 of an ounce (勺)」as droplets and smeared inside shells as mother-of-pearl, the source of motherhood inside the walls of a cavity with two sets of lips such as clams and oysters (see 貝, the goal of emissions).
　「Throughout much of recorded history, a natural pearl necklace comprised of matched spheres was a treasure of almost incomparable value, in fact the most expensive jewelry in the world. …Before the creation of cultured pearls in the early 1900s, natural pearls were so rare and expensive that they were reserved almost exclusively for the noble and very rich. A jewelry item that today's working women might take for granted, a 16-inch strand of perhaps 50 pearls, often costs between $500 and $5,000. At the height of the Roman Empire, when pearl fever reached its peak, the historian Suetonius wrote that the Roman general Vitellius financed an entire military campaign by selling just one of his mother's pearl earrings.」

Nonetheless, stuffing long strings of pearls into「king's meat」and then pulling out the string slowly while in contact with the clitoris is a distinct possibility for MYSTERIES OF PEARL USE, an exercise performed by bored and horny harem concubines for personal pleasure (after their old lord's manhood had died, or, when scheduled late in the concubine rotation), a practice rumored still to be viewable today via the Internet as is most anything else imaginable.
