Update!:

Anima version is released.

OLD (Illustrious):

Gaping and Super Gaping. Super Gaping is just wider version of gaping. There are two variations of super gaping: vaginal and anal. If the desired outcome is gaping anus but not pussy, don't type an additional "gaping". That's a separate tag. And vice versa.

When using super gaping vaginal, additional tags like "clitoris", "urethra" make the output better.

If needed, you can use huge anus to make it even larger.
