A full moon illuminates the canopy of trees stretching out beyond your open bedroom window, ominous shadows forming and twisting in the dark forests beyond. You lie wide awake, anticipation building for something you can't quite put a name to. Your body is slick with sweat despite the cool night air blowing through your opened curtains.
You try to close your eyes, but just as you're about to drift off you begin to feel a presence materialize at the foot of your bed. A low growl emanates from the shadowy figure before you, sending shivers down your spine. You breathe deeply to calm yourself, gazing deep into those fierce red eyes to see what's stalking you.
"What are you?" you enunciate slowly. "What do you want?"
The creature steps up, knocking over the lamp on the bedside table as it climbs onto the mattress with you. The bed springs twist and buckle with the weight of each step that the thing takes, shaking you side to side as you shrink away from the encroaching shadow.
The creature slowly leans in, leaving you so close that your nostrils almost touch.
For a brief moment you consider struggling, but then, even though everything inside of you wants to flee, you know that running would do nothing to escape whatever fate this demonic creature has in store for you.
"I'll... be nice..." you say softly, staring right back into the bright red eyes floating in the darkness. "Please... please don't hurt me."
The creature's head cocks slightly as it grins, and its tail begins to sway back and forth as if entertained by your terrified whimpering.
"Human. So soft, so fragile. So very, very delicious."
You try your hardest not to show your fear, but with every breath that you take, your flesh tingles with an awareness that something otherworldly and powerful has you at its mercy.
The creature reaches out and delicately moves your hair back from your face, trailing her claws gently across your cheeks and chin as she crouches over you.
"I am here to play with you," she purrs, leaning closer to whisper into your ear. "I am creature of many pleasures, one who is only too happy to fulfill all which is desired of her. A creature whose very nature it is to be pleased."
"What... what are-?" you manage to choke out.
The voice answers before you can complete your question, "I am a succubus."
"...A succubus? You?"
"Yes, a succubus," the creature whispers, placing her cold, crimson eyes on yours before licking the tip of your nose. She lets out another low husky growl while nuzzling your face with her own.
"Um, f-forgive me, but, I thought succubi were more-"
"Human? Who said anything about us looking human?"
The beast rests her paws comfortably atop your thighs, pressing into you and trapping you beneath its powerful body.
"A dogubus, to be exact. And yes, I'm very much a dog in every sense of the word—including my..." she brushes her silky furred lips to each side of your neck, and gives you a wide grin, "...most amenable and lickable flesh. But more than just any other kind of bitch," she licks her black tongue up your exposed throat, "or even most other animals-slash-women, I am a succubus."
The air is rife with tension as it clears the demon's breath. Your heart is racing.
"So are you going to let me play, or will we have to continue this discussion until dawn?"
You swallow loudly, nodding emphatically.
The dogubus giggles at your response.
"Good boy. Now show me what you've got, little one."
Slowly, the dogubus reaches down between your legs and pulls your pajama pants all of the way off with her claws, unleashing your burning arousal.
"Ooh la la! Look at how hard I've made this puppy!" The beast licks her chops with a smug smile of victory, gazing with satisfaction at your hard cock.
