You start to struggle

Despite your experiences with your previous straitjacket, you start to twist and jerk your arms, your body covered by the material. But there is nothing you can do. You also try your luck with the clamps locking your legs together, and the D-ring on the floor. But the results are the same. You reckon, if you mouth was free, you could perhaps bite the D-ring open. But what could you do exactly afterwards?

“Mhmpf!” You give out a muffled sound, as you realize this will be it for the time being.
