"Look, I just wanted a shortcut home. On the corner of Adley street and Wiltshire drive. I didn't want any of... this." It said, waving with a good third of it's tentacles at itself.
Wait... roads? When it said 'walking home' it literally meant.
"You were traversing the streets of this city?"
"I do every day, usually not out this late, but things got caught up at the store and I stayed in to help with stock taking."
Harmony's right eye began twitching. What the heck?
"You help at a store? In the city?"
"Well, I know it doesn't earn much, but it's a living. I didn't get into university so..."
"Wait a minute. Are you telling me you were human?"
"Well of course I'm..." It's eyes focus on itself. "Uh... OK, I can see why you didn't get that. Sorry, I'm not used to this. I'm Keith by the way."
"Pleased to make your acquaintance." She says automatically, but inside she is roiling.
She has never heard anyone even suggest a human possessing one of the demons before. Unthinkable! But if it is to be believed apparently such has transpired!
"And you came into this form when Terry was..."
"Yeah... sorry. I... kind of couldn't stop... sucking." He said, eyes looking anywhere but Harmony's face right then.
"In fact you did. Not only did you stop you spat her up. The body you inhabit is a demon from a realm seven steps from Earth. They have been forming breaches into this reality to sate their hunger for nearly a year now. Admittedly it has only become truly severe in the last couple of months, but things are accelerating. If we do not find a way to stop them forming these portals our world will likely be doomed."
Mouths on 'Keith's' body hung open in shock.
"What, they eat women?"
Harmony sighed.
"In a manner of speaking. They gain sustenance from... certain exertions women are forced to perform, them drawing energy from the... experience."
Keith seemed to process that for a few seconds.
"They eat orgasms?"
With a shake of her head Harmony felt any hope this would be an intelligent individual fade away. Likely a horny child, though seemingly of age. He did mention an attempt to get into a college of higher learning. At least he had shunned two examples of his natural focus on women so far.
"To clarify, you eat... ahem, pleasure in women. Such sustenance can be attained by two means. One, a temporary burst of energy from simple copulation. Two, a more permanent source of energy by... ingesting a woman, the poor individual kept inside and subjected to... certain activities that will not be mentioned, the energy drawn off continuously as long as she remains alive within the beast."
"I am not a beast!" Keith cries indignantly.
"It would appear not, given your record to date." She says, with a slight smirk. "Now you merely need to keep up such attitudes. And we must find some ways to keep you satiated, or else you will likely discover your hunger will best your willpower. Either that or you will starve."
"I am not raping someone!" Keith almost squeaks. "Absolutely not!"
"No. You are not!" Harmony says, her voice of authority joining the most severe face she can summon, glaring him down till he crumples backwards. Petty on her part perhaps, but a certain forcefulness is likely going to be required to keep him in check in future. "If I learn you have forced yourself upon anyone there will be trouble." Then her face calms. "Now, we should talk of what must be done with you. You wandering about the college on your own will not be allowed!"
