Formula Xanthan gum 100 % pure. You will be able to create your own personal lube. It is perfect for sex, toys, fist fucking... whatever comes to your mind! Just add 5 g of Fuck Powder and 500 ml of warm water, shake the mix thoroughly until a smooth gel forms and then let the mix settle for 7-10 min and shake again before use. You can mix the 5 g of powder with the cup of the bottle. We recommend to use a thicker mix if you are going to practice fist fucking.
