Earlier in the day Amanda made the claim that she could give out of any bondage with enough time. I offered her a tidy sum if I couldn't restrain her without escape. Blinded by confidence she didn't flinch when I bolded her limbs to the floor one by one. By the time the last strap holding her neck down was in place I could see doubt starting to creep in. After the first 20 minutes Amanda knew she was cooked and wanted to give up. I reminded her of our 4 hour minimum as I secured a Hitachi to her pussy. As I leave her to 'escape', I wonder how many times she'll cum over the next few hours.
