slow drinking of urine under force

I’ve tried my own concept once and it went smoothly. What I did was use something similar to an enema bag, but with a stiff plastic tube at the end so you couldn’t bite through and kink it closed. it is made for young calves that don’t nurse on their own, allowing you to force feed them. You can buy one at a farm supply store. Earlier I froze some urine into cubes and placed them inside the bag. To keep the tube in my mouth, I tied its end with a bandanna using a very tight knot, creating a gag with a tube running through it. I then raised the bag and waited (while in bondage). Within seconds, the frozen urine began melting and trickling down the tube into my mouth. Eww It worked well, but I noticed that tilting my head forward stopped the flow. So what I suggest is wearing a posture collar to keep your head tilted back.
