The padlock is a sexual position in which the receiver sits at the edge of a waist-high piece of furniture or atop an appliance. Tables and washing machines work perfectly for this; givers who need added height may want to consider a short stool. Once the couple is in position, the receiver wraps their legs around their partner's waist, supporting the weight of their own body by putting their arms behind themselves.
This position is also known as the leg lock.
