In our continuing efforts to further bondage science the lovely Amanda has volunteered to be our test subject for today's massive update. In this experiment I secure her with various handcuffs, thumbcuffs, and leg cuffs to see which are the most difficult to unlock. To ensure Amanda gives it her all, she is rigged to a TENS unit that will shock her once a minute until she can release herself. The experiment eventually culminates with her wrist and elbow cuffed behind her back while the Hitachi quite effectively distracts her.
