I'm not sure what your sources are, but incest has different levels of inclusion or exclusion by region. A cousin can be fully included, excluded, or in a hazy middle-ground depending on where you ask.
As for blood related, Aunts and Uncles generally come in pairs where 1 most definitely is blood related and 1 most definitely is not (as they are a married couple and one "joined the family" by this marriage contract). Two siblings share about the same amount of genetic material with each other as does a parent-child pair. What this means is, a grandchild, on average, shares the same amount of genetics with a grandparent as it does with a blood-aunt (ballpark of 25%). grandparent-grandchild versus aunt/uncle-niece/nephew equals the exact same thing. The grandparent thing has the additional taboo of extreme age difference, but that's a whole separate issue. From a genetic comparison of "inbreeding" there is no difference (although I'll grant it gets even more muddy when same-sex partners come into play, as the inability to produce offspring from the pairing completely invalidates the primary purpose for the laws/stigma).
well, you are right. nevertheless cousin relations are legal over here.
besides that, grandparrent is not that impossible (also not due to age) -> example: get child at 16, which get a child at 16 -> result in being grandparrent at 32. waiting for 16 years again results in an 16 year old teenager looking to 48 year old woman (which can still hardly be called a MILF).
But the main thing is:
- man having sex with a girl is fine
- man having sex with her mother is also fine
- man having sex with both at same time is also fine (no law against that)
-> the only question: does a man having sex with 2 women at same time automaticially means that these 2 women also have sex with each other?
=> and mainly incest is seen as sexual reproduction (vaginal sex between man and women) - so is it possible to have incest between 2 women/men at all?
weird situation and honestly i don't know how a judge would decide XD
EDIT: Wikipedia says
Laws regarding incest (i.e.

between family members or close relatives) vary considerably between jurisdictions, and depend on the type of sexual activity and the nature of the family relationship of the parties involved, as well as the age and sex of the parties. Besides legal prohibitions, at least some forms of

are also socially taboo or frowned upon in most cultures around the world.
so there is mentioned that it depends on the type of activity (penetration ???) and the sex of the parties (between same sex != incest ???)
so i guess it would be a social taboo maybe, depending where you live or what religion you are, but not incest as it's mainly meaning

Consensual sex between adults (persons of 18 years and older) is always lawful in the Netherlands and Belgium, even among closely related family members. Sexual acts between an adult family member and a minor are illegal, though they are not classified as incest, but as abuse of the authority such an adult has over a minor, comparable to that of a teacher, coach or priest.
