Cum gushing out from mated sex organs due to excessive orgasm or filled beyond capacity
Cum should leak or even spray out from the stretched walls of a stuffed vagina (tail hole as well?) when it's filled to capacity with cum + cock. Perhaps a displacement of fluids effect due to phallic object entering a hole and pushing the fluids out. (It all has to go somewhere right?!)

I don't know about the vaginas because the dripping arousal effect made me not so sure about it, but messing around it seemed like it did build up how much semen was up a character's rear end. Plugging it back up again with a penis would stop the dripping and removing would remove it further. Dildos did not seem to prevent it from leaking out however. I was going to post a suggestion about toys/fingers preventing leakage in addition how it works now, but this is a nice suggestion to go along with that:
Have the fluids build up when plugged up with a toy/penis/finger but an option for overflow after extreme buildup is an interesting idea to go along with it too. It opens the possibility for all kinds of ideas like the semen collection toy/device that never came to be in the first Rack. I'll have to go through the suggestions and see if anything like that has been brought up yet too.
