The frogtie bondage position is one in which both the bound person's legs are bent and the ankle and thigh are tied together.
This bondage sex position can be achieved with rope using a double column tie or with other restraints made for this purpose. When this position is achieved, the lower half of the bound person’s body resembles a frog’s legs. This tie is often completed with the wrists either tied behind the back or to the outside of the ankles.
