Wakamezake

Wakamezake, also known as "wakame sake or "seaweed sake", is a Japanese sexual practice in which sake is poured down a nude woman's chest, collecting in the space between her closed thighs and pubic mound. The woman's partner then drinks from the makeshift cup. Wakamezake was allegedly performed along with nyotaimori (the act of eating sushi from a woman's naked body), serving as a "traditional finale" of sorts, but health code restrictions and decency laws have sharply curtailed the practice. Wakamezake derives its name from the woman's pubic hair, which is said to drift in the sake like seaweed in the ocean.
