Bondage in SL (Second Life) is quite elaborate and yes, self-bondage is possible, and unlike in real life, it can be much more effective!
To give you an idea, I will describe, what is possible with the ropes that you can see in the movie and some of my pictures (thanks to Marine Kelly who created the "Shibari Arms" and "Shibari Legs" for very realistic rope play).
First of all, you have to "wear" all the items that belong to the ropeworks. This is easily done, you can wear groups of stuff with a simple right-click menu. Wearing the arms rope set, does nothing, but show a small rope ring on your right wrist. The legs rope set applies a similar ring to the right ankle. When you click the ring, you will see a menu that allows you to pick a bondage style and tie yourself up instantly. In order to get free, you simply click the "untie" button. Instead, you can click "more" and set a timer for the release. Once you did this, there is no "untie" button and many other options are disabled. You can only "tug", "squirm" and "struggle" now, which might eventually free you, or wait for the timer to run out. Also other people can tie you up by clicking on your wrist rope. This will instantly disable most options, especially the "untie" button. Only the person who triggered the bondage can free you. Others get a menu with a small game to solve, if they solve it, they can free you (and instantly tie you up again of course).
There is a second timer called "autobind". This one will trigger bondage after a set time, you can select a style and also set a timer for release here. Once autobind is activated, you can't control the ropes anymore but there is a nice feature that allows you to transfer the same settings to the set of leg ropes, a ball gag and a blindfold (which - of course - you have to buy separately from Marine Kelley). All these devices will then be triggered at the same time and let you go once the release timer has run out. If you set no release timer, you can untie yourself instantly.
This is nice already, however, you can always take off the items while bound. If you put them on again, they will remember the status and tie you up, timers will start running again etc. but there is a solution to that as well: You can download a special game client that will prevent you from taking off everything that is "locked" on you and compatible with the "Real Restraint System". It also comes with various other possibilities to enhance bondage and submission. In fact, it has been programmed for exactly these purposes. And the author is again Marine Kelley. There are other "alternative viewers" that do the same and all of them seem to have their pros and cons. I am using this original (it was the first one) and here is the link for downloading it: http://realrestraint.blogspot.com/search...rainedLife
