It is also a modification of other found. You must be tied to a chair, ankles to the back legs, thighs to the front, wrists to the back of the chair as in the picture in my blog, where will be our padlock. A ring gag, and must be tied up from the back (neck) to the chain or rope of the wrists, forcing you to keep your head up.
On the other hand we filled a bottle with water or any liquid you want. I use a plastic bottle, I filled it, and I make a small hole at the plug. Small!!!, it controls the amount of liquid that we drink. Hung upside down with a rope down ( from a lamp or a ceilling point ). The drip must aim to the hole of the ring gag, forcing to drink what falls.
I put a condom to the bottle, securing it with a rubber band in the part before the plug. The liquid will fall by the condom and swells it. The bottle must be placed at a height that when the condom swells, it must enter in my ring gag. Of course you have to make a small hole in the tip of the condom.
The release method...a rope holding the key of the padlock as a ice timer. When the ice melts will release all the rope and the key will be at the height of our hands to be released.
You have to be careful and test before the rate of dripping!!!
As complements, what you have, I used clamps on the nipples tied to the ring gag, dildo into vagina or anus, if you have electrified plug, so good!!! ( I don't have it,
