I would recommend not to tie the rope to a collar, but to clamps on your nipples. You might also add that you sit on an vibrator. To make it more fun.

How to:
Always play it safe! Do NOT do selfbondage in real-life unless you really know what you are doing! In real life, tying yourself up without a sane and sober person nearby (and a backup for getting released) is just plain dangerous. This is just a piece of fantasy!
1. The rope to the heater is not tightened yet, so she places the cuffs next to her in a position where she can still reach them when the collar is tied to the door. The cuffs are already connected by a loose loop.
2. Tie the collar to the rope from the door/ice bag.
3. Put on the cuffs.
4. Reach for the other end of the rope coming from the ring device. Pulling it will pull the cuffed hands towards the heater, and towards each other as the loop also tightens.
Release: When the ice in the bag has melted, the ring will fall off and she can shuffle backwards to the heater, which means she can use her hands again and untie the rope.
