Device for fake cum enema

Hello,

I have been thinking of how to make a device for doing a fake cum enema, and my idea is to combine 4 pump syringes (1.5 liters in each) in a wooden frame. By combining the tubes from each of the 4 syringes into one tube, that tube could then go into a dildo with a hole through. This dildo could then be placed in some kind of chair. By adding a wooden plate above the 4 syringes, they could be simultaneously be pushed down by adding a weight of some kind. The wooden plate would be steadied by connecting it with the wooden frame, so that it could slide gradually downward. By removing the weight, the flow of fluid would stop. The total capacity of the 4 syringes would be 6 liters, which is more than sufficient.

Anyone else having experiences and ideas for homemade enema equipment?
