When he returned, he was holding a dark length of cloth. "Lean your head forward," he prompted, and when she complied he tied the cloth around her eyes, blocking her sight, but shifting the knot to the side so she could lean her head back on the headrest without discomfort.

I’m about to place nipple clamps. They will hurt, but only for a moment. Gradually you will become accustomed to them and will only notice them when I tug on the connecting chain. When I take them off at the end, blood will rush back to your nipples and it will feel briefly painful, but the sensation will pass. I assure you the pleasure you will derive from these will far outweigh the pain. Tell me you understand."
