I would say no, under the Supreme Court decision in Miller v. California, 413 U.S. 15 (1973), and as modified in the context of child pornography in the Court's decision of New York v. Ferber, 458 U.S. 747 (1982). But you can read these decisions yourself, using the link. In fact, if you read Ferber, I think you will find that the images at R'osity aren't likely to fall under the category of virtual kiddie porn, even if the Court upholds the most recent legislation on the topic.
