Grinding bean curd, an online buzzword, is a sexual act between lesbians. They split their legs, their genitals overlap and rub against each other, and clitoris friction produces pleasure, thus reaching an indescribable state, commonly known as grinding bean curd.

We often encounter words like "bayonet" and "grinding bean curd" in film and television works and on the Internet. When it comes to grinding tofu brain, a Chinese Odyssey is probably the most famous source. When the top scholar of Dashu High School returned, the two ladies wept with joy. Uncle Da said, "Mrs. Hard work grinds tofu brain", and the expressions of the two ladies immediately became shy. This situation is very interesting.
