The hydraulic maneuver is a sexual act , it can involve the vagina or anus , it is typically male on female but can be performed male on male , the anus or vagina is filled with urine then the erect penis of a male is forced into the entery bole of said anus or vagina , the entrance creates a tight seal on the shaft of the penis , because the cavity of the vagina or anus is full of urine this cavity and urine becomes hydraulically pressured by the entering penis , this sexual act can be performed with alternative fluids but for the authentic hydraulic maneuver it's best to use urine
