Have you ever tried to build a house of cards? Not entirely easy. Now then, try doing it when you are a Nude in Metal girl like Natalia K!
Ankles locked to together with rigid police handcuffs, then each wrist handcuffed to an ankle too. Tricky, but not inherently impossible. She can manipulate
the cards, and see what she's doing. She manages to make two cards stack up very easily. Moving into position to get the second pair of cards is harder,
but the real nightmare comes from the propensity of the cards to fall down when the cuffs brush them, or even move too close and the draft makes them fall.
Will Natalia win her treat, or will it be punishment time?
