As the Escapist article on it [http://www.escapistmagazine.com/articles/view/columns/the-needles/7388-Lets-Not-Ban-RapeLay] said; no.
When it comes to fiction, absolutely anything goes. If it doesn't hurt any real persons, then it doesn't need to be banned (although due marketing restrictions on it only being sold to adults are in order, assuming it had ever been sold here).
The whole discussion is essentially irrelevant though; As Rapelay isn't sold anywhere in the Western world, the only feasible way anyone would get of hold of it here would be downloading a copy of it off the internet, which is already illegal as a breach of copyright law. So it's de facto illegal to obtain it anyway.
