A bondage frame in the shape of an X used in dungeons to restrain a submissive. A submissive may be restrained facing forward or backward with his arms, waist, and ankles tied to the frame. Also known as St. Andrew’s Cross.
The ends of each beam have attachments that a person can be cuffed to from their legs and ankles. Much like the A-frame, the sub can be tied either facing the cross, to allow spanking and whipping, or tied with their back to the cross, leaving their breasts and genitals exposed for teasing.
The name comes from its shape, which is said to be identical to the cross St. Andrew has been martyred on.
