Pulling your foot, it comes out easily and no worse for the wear. Still, you decide that you've had enough and go home as fast as you can, leaving the night's events seeming like little more than a bad dream.
But it wasn't a dream. The latex was real. Not just real, but legion - an entity risen from some dark, forgotten pit, whose only purpose was to sate its hunger. However, this was no ravenous hunger; for centuries it had gone without a meal, and the man it had consumed was to last it for centuries more... until, that is, it had touched you. This hivemind driven by pure instict had ended its starvation, but now it knew a new sensation: lust. Not a sexual lust, for this being's purpose was far too strong for such mortal wants, but a pure obsession. After eons of existence, millenia of wanting only to consume, it had a new purpose. It wanted you.
And so, this lust driving it, it formulated a plan, using an intellect it hadn't accessed since its creation. Soon, it would have what it so strongly desired.
