Rope or Leather, both restraints offer their own unique sensations.
Rope, Shibari style, fits the body in a custom wrap of sensual immobility using simple to intricate layers that lease and the sub.
Leather can be a more restrictive, less flexible but a different type of bondage, from simple cuffs and collar to full body and head harnesses with no give, only the creaking and smell of leather pushing the sub into space.
