Hey guys!
I managed to finish the simulation settings for this scene earlier this week. I set up the oral and anal+squirt leaks separately. Two separate boxes with low resolution. It turned out pretty good. Although the squirt is not as chunky as I would have liked. Unfortunately I can only set the viscosity to a variable value, not the surface tension or the sheeting effect. I brought some rendered pictures of that.

Now I have enlarged the box (domain) size to fit all the leaks and set the resolution to final. I have started the final simulation. The scene is 900 frames long and currently FlipFluids predicts 200+ hours of remaining time. This will decrease nicely in a few hours.
I hope there will be no errors and then only the final scene remains. Which is a significantly simpler animation and I can use the cummix simulation settings from now on.
