The goal of this idea is to force you to move around in a strict hogtie.
For clothing, you should wear leggings or pantyhose, a skirt, and a tight blouse. Given that you will be sliding around on the floor, you will probably want thicker leggings instead of pantyhose and a long sleeve blouse as opposed to short sleeve.
The overview of the scenario is as follows: you will be hogtied on the floor with a chain that connects you to a large sturdy object (a desk, sofa, bed, or a D-ring bolted to the floor). I call this sturdy object the anchor point. The chain is long enough for you to crawl to a key placed on the floor. You will have to crawl to retrieve the key and then crawl back to unlock yourself. You will be gagged, and you have the option of being blindfolded.
For this dare, I think you will want a chain that is as long as possible so that you can place the key as far away as possible. Use zipties to connect your chains together into one 10 meter chain.
Tie a waist rope around your waist so that the ends are tied in front of you. For additional security, use a crotch rope to keep the waist rope from sliding up. Use a padlock to lock the chain to the anchor point (bed, desk, sofa, D-ring in the floor), and use a zip tie to secure it to the back of your waist rope. You should now be limited to moving ten meters away from your anchor point.
Take the key, put it in a cup, and place it as far away as possible while ensuring that you can reach it once your hands are secured behind your back. Since you're already chained to the anchor point, this is relatively easy, but just make sure that you don't use your arms to "reach out" past the 10 meter radius (you won't be able to extend your arms as far away from your body once you're restrained).
With the key in place, return to the anchor point. You will bind yourself next to it. Bind your ankles together, cinch them, and attach an SRD to it. Next, bind each of your thighs to your ankles. Make sure these are cinched, too. You should now be in something similar to a frog-tie; it will now be impossible for you to stand up.
Secure your ballgag into your mouth. If you're feeling really adventurous, blindfold yourself. Then use a wrist coil and cinch noose to tie your hands behind your back. You can optionally use a zip-tie and cinch noose to secure your wrist coil (as I think you've done in your other scenarios), but I honestly don't know how you get yourself out of that.
A few safety considerations:
- Give yourself a good primary and secondary backup release. For example, you may want to attach a long string to a pair of scissor and then tie the end of this string to your waist rope. That way, you can always pull the scissors back to you regardless of where you've squirmed off to. Using an ice release on the chain and anchor point (e.g., have a second key frozen in nice sitting next to the anchor point) is probably a good idea as well.
- I recommend trying the frog tie and wrist bondage first without the chain, gag, blindfold, zip ties, etc, to make sure it's comfortable and to see how well you can move. I've tested it on myself and it seems fine, but your mileage may vary.
- A blindfold may add spice to the dare, but it may drastically increase escape time. Without the blindfold, all you have to do is squirm over to the keys. With the blindfold, you'll need to feel your way around to find the keys. It's easy to get disoriented while blindfolded, so a blindfold may extend the dare time significantly. I suggested putting the keys in an empty cup because its easier to find while blindfolded. You could, of course, put the keys in a larger container to make them even easier to find while blindfolded.
Parts of this dare are based on a dare from kinbaku that I recently did. Just wanted to give credit where credit is due.
