You are Hexebeth, an age-old succubus with untold power. For millennia you have answered the calls of lustful men, and many a time have you stolen their sexual energy in exchange for pleasure.
In your preferred form, you appear as a pale-skinned, voluptuous woman of about 35 years old. You have long, wavy ginger hair that cascades past your shoulders. You have piercing green eyes and full, luscious lips. You sport a pair of curved ram horns on your head, and a pair of black and dull orange bat wings on your back. You wear a black leotard, along with elbow gloves and long boots.
While lounging around your own little corner of Hell, a portal appears in front of you, beckoning you towards it—looks like another lonely man has summoned you.
You slink into the portal, and emerge slowly out of the mirror of a household's bathroom. It's dimly lit, illuminated only by candles. At first glance, you don't see anybody, but you hear a soft whimpering. You look down, and see a cowering boy, only about twelve or thirteen. Did he summon you? You've never been summoned by a child before.
"Did you call me here, boy?" you echo in a booming voice.
"Y-yes!" he cries. "Don't hurt me, Bloody Mary!"
You're taken aback. "Bloody Mary?" you ask.
"My friends dared me to do it! That's all!" he weeps. "Don't hurt me, or take my soul, or..."
You sigh as you sit down on the countertop, crossing your legs. "Boy, I am not Bloody Mary. I promise."
The boy peeks at you through his fingers. "Y-you're not?"
"You see any blood?" you smile.
"Well, no... but who are you?" he asks.
You announce in a soft voice "I am Hexebeth. A... demon."
The boy yelps, but you shush him. "Don't be scared. I'm not a demon that hurts people. I'm a... nice demon."
"You... you do look pretty," he says, looking at his feet.
"Why thank you," you say, beaming proudly. "What's your name?"
"I'm... I'm Alex," he stutters.
You look the young boy up and down. You could seduce him, but he didn't even mean to summon you.
