Rigid Restraints - Luna Rival - Luna's restraints hold her tightly

In this sequel to Supple Restraints Luna is bound with only metal. These restraints are harsh and unforgiving. Each position is unyielding. Luna struggles, but there is very little option for her. Each movement is painful and tiring.
Bound in this way she is completely at the mercy of her captor. He removes her clothes without any fight from luna. She just lays there as he exposes her. If she could move she probably wouldn't though. It's clear she's enjoying her ordeal.
The tight fittings Luna is bound with can be arranged in various ways. Exploring each and what new level of hell each one is is exciting and tormenting for Luna. She has no option to evade when a giant dildo penetrates her from behind.
