The pony was in full tack with high pony boots that had no heels, requiring her to take her weight on her toes, and which opened into hooves with horse shoes. A high collar around her neck connected to a full martingale and bridle straps that went around and over her head insuring that she could not turn her head. Her bit seemed to be of metal and the lever arms from the bit were connected by light chains to rings in her nipples. The reins were connected to rings in these chains a third of the way down from the bit arm. Any tension on the reins pulled down on the bit arm, but also pulled at the nipple ring. Amber felt her own nipples harden. If she had use of her hands she would have given her breasts a sympathetic touch.
