Wax Knuckle Bearing Juice

Wax Knuckle Bearing Juice refers to the act performed by two or more gay men. Hot wax is poured over one of the participants' hands and allowed to cool until the wax hardens to a consistency that will allow the wax to work as a lubricant during an anal fisting session. The idea behind this is that the residual heat from the wax will bear "anal juice" thus completing the Wax Knuckle Bearing Juice.

The act was first noted in a blog entry in May 2025 on blogger.com

Bruce suggested to Gene that they perform the wax knuckle bearing juice maneuver on Jason.
