Under UK law it would be classed as extreme porn, same under australian laws.
In that a law was recently passed 'for the protection of children' (that old chesnut) a similar law was passed in Aus.
In that a Man in the UK was taken to court for a comedy cartoon of tony the tiger (frosties

)
Having sex with a woman. It was a clear case of comedy as he said "beats working in advertising
This case was correctly quashed but they got him again:
http://www.theregister.co.uk/2010/03/22/six_second_clip/ he is in sing sing for 6 months.
In Australia a man was convicted of holding cartoon porn of the simpsons, he got 18 months.
This falls under the category of extreme porn in that the Home secretary said there was a link between murderers and extreme porn, in that on the hard drive of a murderer he had strangle sex videos, and she made that link based on one case.
You know the old bullshit about how video games make people more violent. The law was passed, it is deliberately vague so that it is a catch all for thought crime.
In that there are some definitions clearly defined:
Child porn
Rape
Situations where consent cannot be withdrawn (gagging in UK porn is illegal)
Situations where long term harm may come to a person (BDSM, even porn where the stars have big cocks as it may 'damage' the other person irrepairably)
Torture
All sorts of things.
Games such as rapelay have almost ALL of the above, hence you get caught with that then you go to prison for 6 months, get put on the sex offenders register... which is odd because there has been no material harm, in that nobody was raped murdered or tortured in the production of the above, which means purely it is thought crime.
This law was introduced as a catchall to save embarrassment, in that EVERYBODY has some sort of porn on their PC, and the government have been embarrassed regularly by their shit laws when they raid 'terrorist' bomb factories and find nothing.
They will smear the occupants even though they are innocent to make it look as if they were justified. The two london men where the police attempted to execute the men (the gun was supposed to have gone off accidentally yeah right). They found nothing NOTHING at all.
So the police put out lies online that they were kiddie fiddlers which was untrue as they were never convicted.
With such a law of extreme porn itis such a wide catch all that even if you are raided and subsequently found completely innocent they can still pin you with an extreme porn charge.It is like operation Rize where they went and bust open 6000 safe deposit boxes, they said 96% were proceeds of crime, a year later it was revealed as 4% as proceeds of crime. But this received no mass media attention and thus people thought they were guilty.
Same with the brazilian executed lies about him being a rapist were spread by the POLICE,
