This is not real.
Making the rounds online, the "Nude Gaming Party" is a not-at-all disguised ad for XtendPlay ergonomic PS and Xbox controllers. (They out themselves in the YouTube link with their URL and the question, "Would you attend nude gaming parties if they were real?")
Fun little ad, which must have been particularly entertaining to film. I think YouTube user masterneme speaks for the entire internet in the comment, "Uncensored version NOW!"
