like, zombie-dead or dead-dead? because i'm thinking about it for the first time, here, and fucking a zombie might be interesting. although i think it would be better for a guy to fuck a girl zombie. tie her up good so she can't possibly infect you, bent over, and fuck her while she thrashes around wildly and snaps at you, trying to sink her teeth into your flesh. hot, right?
you would probably want to wear a condom, though. those crazy bitches would likely try to trap you in an unwanted baby situation.
