My slave gummi is the resident rubber whore. If there is a new rubber thing, it get's tried on him first. So when I got an amazing new military green latex vac vag, I summoned him to experiment with. After tying him snugly in rope, we slip the latex bag over his body. Almost immediately he is paralized by the strong vaccuum. Now I can toy with him however I please and he cannot even move a pinky to resist.
