but there is an adult site completely unrelated to the topic on the .com
Are you thinking of type-ins going to the wrong domain?
Insofar as the regular SERPs are concerned surely the adult site should be filtered out if you have plenty of good quality content?
FWIW my primary B&M example.com site is both an adjective and a noun and the plural of it has an adult site on it, that is never seen in any of the SERPs however YMMV!
