That's actually one of my pumpkins, sitting on my very own gatepost. I did consider carving a cock on it, but I am a parent and need to get on with my neighbours and keep my filth-peddling side a bit quiet, at least locally. But I have been idly thinking about spooky erotica this week, partly due to having recently finished a short story on the subject. Horror and porn are two things that get unimaginative people irritatingly and predictably worked up, so it's not that surprising that mixing them results in a potent and exciting brew.
Back when I used to review porn DVDs, I had a lot of time for a company called Relish whose stuff tended to be both smart and silly, with an air that all concerned were having a bit of fun rather than exploited, degraded, trafficked, hated etc, and I have fond memories of them having a go at the horror genre...
There were also a few zombie-shagging efforts, though I don't recall anyone doing an actual porn film about werewolves (I am prepared to be corrected if someone has superior knowledge). In book terms it's been even more of a successful combination. I discovered the Anita Blake novels in the late 90s and was very taken with the blend of spooks, mayhem and soft-core sex which, in the later ones, got progressively harder, but that didn't stop me being a bit gobsmacked some years later to find that WH Smiths had a whole section devoted to what they called Paranormal Romance and what we had previously called vampire smut. Werewolves featured fairly heavily in the novels, perhaps on the grounds that writing a book about shapeshifting is easier than spending an extra chunk of the budget on fake fur and a skilled make up artist - but I don't think I've so far discovered much in the way of zombie sex in fiction.
It's not a genre I've done much with myself so far, but I think there may be possibilities in the concept of an erotic poltergeist. Given the state of my boudoir, I think I might have already got one.
