【中文乳胶男M】玩乳胶真空柜很有趣。在这种情况下，你只能直立，头可以从顶部伸出来。Vac cubes are fun to play with. In this case it's a vertical vac-cube from Rage Rubber (which now seems to be out of business). A vertical vac-cube is really no different than a square vac-cube except that you can stand upright and your head pops out the top.

In this video the fun comes at the end of the vac-cube session, when Rank challenges his friend to escape from the cube without ripping the rubber. This doesn't seem like a big deal until his friend discovers that the zipper is an industrial model with the handle on the outside, not the inside. Hummm... This doesn't stop him though, and he implements Part-2 of his escape plan. Check out this hilarious video and see what Part-2 entails. Visit Rank’s rubber blog at
