I frequently pull the plug on inflatable beds, chairs, and even inflatable dolls. Its quite a turn on to know that the entire ob<x>ject is being held up by a small little plug. Right when the plug is removed there is a loud Phusssss but nothing happens for about a second or so then the whole thing falls in around you. No more support no more bounce just soft mushy plastic then about a minute later you are on the hard ground.
I sadly don't own anything inflatable, though I wish I had a bunch of living inflatable girls, that would pull their own plug and deflate on me, or even pop themselves ;)
