My sister's best friend asks me to eat her pussy and I do.

If a friend of your sister asked you to eat her pussy, would you? I don't think so, damn it, you can't do that because then these things cause problems with the number of pussies in the world looking for tongues and dicks, haha. But of course, others don't think twice, like the guy in today's porn video who eats it, oh boy, does he eat it...
