Concept by  fatalglory128 , art currently only by  fatalglory128 (hopefully Rik will sketch in a character to illustrate how the machine is used ;)

The Stuck Machine! Basically the ultimate place to get wedged in place. It's designed to be stronger than three musclefurs and programmed to react to the user. As you can read in the image it basically has three modes, Static, Dynamic, and Gasm. The difference is that in Static mode the hole stays the same size, dynamic it will actually clamp down around you when you pull, and gasm mode it will only let go once it senses the user climaxing.

When it's not in use, all the jutting out parts retract and the machine essentially becomes a large table that can be used for eating and stuff. The machine is about 4 and a quarter feet wide and 8 feet long, and the surface stands at about 2 feet high. It's big and strong enough to handle any size fur outside of macro and micro, and adjusts to fit whatever size fur you are. It's completely customizable via the control panel, and you can change the program however you want. (wow, I'm actually sounding like this is a real product I'm selling XD )

Basically, his thing is awesome, and it's absolutely an amazing place for when just the doggie door or the window isn't good enough ^^
