I apologize in advance for this "essay". If you don't want to read it, don't. You probably won't agree with it anyway. I know I'm not expressing the popular view here, (which is, of course, extreme disgust and abhorrence), but I think it's important to argue both sides of this topic.
This wasn't even what was originally asked. You all decided to weigh in your opinions on the subject and, in some cases, package them as fact. Well, there are two sides to every coin. So here we go.
I probably won't respond to any comments on this, because it's pointless to argue against people who already have their minds made up, but if you feel the need to comment anyway, feel free.

I never mentioned I thouht she was underage. My point is clear a RL father/daughter (no matter the age or exact relationship - birth/step/adoptive) engaging in fantasy incest is not an acceptable behavior. You wouldn't want this to be your family, and you wouldn't want to be associated with them in any way because you know it is dangerous and destructive abnormal behavior. The reason it is dangerous and destructve is because it involves serious mental and emotional control and manipulation.
Please do not presume to speak for me.
I'll agree that such behavior should be classified under "abnormal", because, agreed, it is not the norm in our society by any means. But "dangerous" and "destructive"? "Involves serious mental and emotional control and manipulation"?
No, not necessarily.
I don't want to get into a huge debate over whether or not incest is morally right (if there -is- such a thing as "right"

, but I just don't agree with you 100% on this.
It is quite possible for an incestuous relationship to be dangerous, destructive, and the result of mental and emotional manipulation. But it's also possible for ANY relationship to be dangerous, destructive, and the result of mental and emotional manipulation.
It is not as uncommon as you might think for women to marry men they thought were wonderful guys who would never hurt them, and, lo and behold, the husband starts raping, abusing, manipulating, and emotionally damaging the woman until she starts blaming herself for hating her husband and begins thinking everything is her fault. I heard about one woman who was a basic prisoner in her own house for something like 15 years? She had a room. And her husband fed her (sometimes) through a hole in the door. And that, unfortunately, is not really that uncommon. It happens.
That sort of thing is extremely sad, but has nothing to do with incest, and happens a lot more often than abusive incestuous relationships.
Thing is, if the child is grown, they can make their own decisions. And if it is a manipulative relationship, then it's no different from any other manipulative relationship. It's sad, yes, and the victim (and the assailant) need help, just like any other person in that situation.
Such a relationship could also be very healthy, though. Just like any other healthy relationship.
If the child is underaged, then it's technically statuatory rape, but-- I know no one wants to hear this, but-- underaged people can think for themselves. It is quite possible that an underaged person could be the initiator of such a relationship. Or the adult could be the initiator and the child could be okay with it.
Because I really like studying people's sexual and mental idiosyncrasies, WITHOUT judgement, I do know several pedophiles, and every single one of them would never, ever be able to do anything to harm a child. They almost worship them, see them as infinitely precious, would never be able to say no to them, about anything, etc.
I'm not saying it's not possible for the relationship to be sour. It is quite possible for an adult to take advantage of a child, ESPECIALLY if it's a parent, because they are such influential figures in a child's life.
But, it's inaccurate to say that all relationships of this type are dangerous, destructive, and the result of mental and emotional manipulation. Because they aren't all.
Incestuous relationships are not only accepted, but encouraged in some parts of the world. Does that mean the people who engage in them are wrong, backwards, sick, etc.? Whole tribes/races/nations of people who do are wrong, backwards, and sick?
What if they find -us- wrong, backwards, and sick? Who's right?
I say: Who the Hell cares? As long as it's not harmful in any way to anyone, then just look the other way if it bothers you.

Im not voicing my oppinion on the subject matter being discussed.. but disagree with this thought. If the daughter IS underaged, I think it is possible reason for lot people to be concerned.
Concerned, sure. It's not normal in our society. Anything that's not normal sticks out and is the cause of concern. That's the way people work. And, yes, it could indeed be a very bad situation. So it's fine for people to be concerned, to a point.
What I'm not happy about is people just coming in here, going "OMG THAT IS SO GROSS OMG EW THAT PERSON NEEDS SOOOOOOOOOOOOOOOOOO MUCH THERAPY OMG" and then leaving. We weren't asked to pass judgement. We were asked if that situation counts as incest.

Wouldnt be a far leap of logic to believe if the father is forcing her in RL (once again if underaged) to perfom sexual acts in SL, that its just a primer for a RL molestation.
That is a very real possibility, sure. It's possible that the father in this situation could be blackmailing the daughter or threatening her with physical abuse if she doesn't comply. I'm not saying that's not altogether possible.
But that's also not the only possible situation, and, since no one knows what the actual situation is, if, again, it is a situation at all, it's probably better NOT to come in and stomp around about morals and OMG THAT'S SO GROSS, HOW CAN ANYONE DO THAT, etc.
Be concerned all you want. It's good to want to offer support if you suspect a bad situation, but, with all due respect to all of those who have posted, it could be nothing, and it's a bit rude to automatically assume the worst and then proceed to rally about it in a public forum with no information whatsoever.

...An experience with an adult may seem merely a curious and pointless game, or it may be a hideous trauma leaving lifelong psychic scars. In many cases the reaction of parents and society determines the child's interpretation of the event. What would have been a trivial and soon-forgotten act becomes traumatic if the mother cries, the father rages, and the police interrogate the child.

[And, by the way, I would be extremely interested to talk to anyone involved in the original question, if there are such people. This sort of thing interests the Hell out of me. Feel free to IM me in-world if you exist.]
