Depends.
Parent and child, siblings where one is significantly older, aunts and uncles, much older cousins. These can all be pretty iffy. There is a chance the younger participants have been groomed into it.
If they'd barely seen each other in their entire lives, sure, why not. It's consentual, there's probably not any mind fuckery going on. They're welcome to do as they please. We have contraception now, there is no reason for it NOT to be okay.
I mean, sure, it's pretty gross, but it's not really anybody's business. Taboo is not a legitimate reason to keep two people who love each other apart. If you remember, being gay used to be (and still is in some parts) this huge taboo, and I would like to think most of us here are pretty aware how stupid homophobia is.
