With a CCC.com that's parked, I highly doubt that you are getting any traffic from search engines, so unless you're focusing on SEO for a developed site, it doesn't really matter what Google thinks.
However, if you don't have a vehicle in place to monetize adult traffic, then redirecting them to another domain probably isn't going to be beneficial at all. You're just consolidating your non-converting traffic into one massive pile of crap, lol...
Maybe you're best bet would be to find an adult affiliate program and redirect all the traffic to their site using your affiliate link.
