My mother had always told her kids: if you're about to do something, and you want to know if it's a bad idea, imagine seeing it printed in the paper for all the world to see.
I grew up in the '80s where there's a lot of these kind of post-apocalyptic, post-comet, post-whatever it was, so that always captured my imagination a lot as a little kid, that idea of getting access to secret places and being able to roam around where you're not supposed to.
Women get consumed. Not surprising, considering the sheer amount of traffic a woman's body experiences. Tampons and speculums. Cocks, fingers, vibrators and more, between the legs, from behind, in the mouth.
My imagination is more tweaked by imagining the lives of the people who were there before us. I don't need to give myself the willies. I'm quite good at that - I can freak myself out wherever I am.
