Oatmeal and glycerin

I'm planning on taking an oatmeal enema for my online daddy and he wants me to add some glycerin to make me cramp and make it hard for me to hold.

Can anyone advise what kind of proportions I should prepare in order to get the desired effect?

I'd like the enema to be quite thick so I'm going to make it with oatmeal and water and heat in the microwave before adding the liquid glycerin.

Thanks for any advice!

You are going to have to inject this mixture with a bulb or pump of sorts because it is not going to flow from a bag down a hose.

This is going to be more a punishment for you to clean your enema equipment than anything else. You might even want to just throw away the hose. DON'T use an open top bag--you'll never get it all cleaned out.

Don't worry I'm going to be using a cookie dough mixture syringe to insert the enema. Very easy to clean afterwards. I want it nice and thick!

This is what I'll be using:
