First, the circle must be strong enough to hold the demon for which you're summoning. Then, you must create a space within its confines where a being made of pure magical energy can survive. Next, you make the lure. For a succubus it's always arousal within the summoner.
Finally you open the door into the dark realms and wait until something pours through.
In case you were wondering then yes, managing all this at the same time is not an easy task. Thankfully, the Nocturne Compendium taught me how to make all these elements of the trap self-sustaining once they are in place so that a warlock doesn't need to maintain concentration if it is successful. Of course, if something went wrong, any number of things could happen, from me being killed by a lady of the dark realms to opening a rift in the dimensions big enough for something truly nasty to get through.
So, being young and stupid, I quickly got to work setting up the elements and then I awaited my catch. Yes, at the end of the day we warlocks have more in common with trout fishermen than we do with your average devil worshipper.
I waited 30 minutes before anything happened. I heard her first in the sound of a soft little moan that echoed throughout the room reverberating with a scintillating edge. Then the centre of the circle came alight with a burst of green flame that almost singed my eyebrows before it flickered out to reveal my catch.
To this day one of the most pleasant memories of my entire life was the first moment I saw Channa. She was all that was advertised and more.
Her body was a perfectly proportioned collection of slender slopes with just enough curve at her hips and her breast to make my mouth water.
Skin of smooth, luscious alabaster covered her wonderful womanly figure. Settled upon her knees, her heels tucked against the heart-shaped cheeks of her bare bottom, she made a sinfully submissive sight for my hungry eyes. Long, slender legs were folded against themselves and parted to show a naughty strip of jet black hair at the apex of her thighs. Beneath that dark Little tuft were the bright pink lips of her already glistening pussy, parted slightly to show a hint of her welcoming depths.
Her hips narrowed into a tight waist with gentle inclines of taut muscle flowing up toward nicely-rounded, moderately-proportioned breasts with perky, rose coloured nipples. When I laid my eyes on her face I felt my heart starting to thunder against my ribcage. I saw a vision of female perfection accented with dark carnal allure and framed in a cascade of silky black curls.
Of course the fact that this was no ordinary woman was immediately evident. I first noticed the long black claws that tipped her fingers when she moved her hands forward to slide them down upon the floor.
Those Long vicious digits settled on the ground between her Legs as she leaned toward me. She looked at me with gleaming eyes, the colour of freshly polished rubies with Long slitted pupils at their centre. Those dark little slits slowly dilated as she looked upon me the same way I'd only seen women look at a tub of chocolate ice cream. Her brow was adorned with two long slender black horns that curved backwards along her skull.
I'd done it. I'd summoned a demon.
I was also pretty damn certain that I'd fallen in love too, but that was beside the point.
“Well? Do you speak?" Her voice had me moving toward her before I caught myself and rallied my willpower enough to stay back.
As you can imagine, I was a little bit stuck for words. I think during those first years I was waiting for my hobby to disappoint me. I could move a pencil, but I probably couldn't levitate one. I could summon fire, but probably couldn't write my name in the sky with it. I could imbue magic into things, but I probably couldn't summon anything from the dark realms.
So far my cynicism had been wrong at every turn.
“Hello. Er... may I have your name?" I suddenly remembered what I planned to do if anything actually did happen.
The question made the beautiful and thoroughly deadly creature suddenly grin at me. She flashed a set of very sharp canines and incisors amongst gleaming white teeth. The way she kept eye contact was damn well un-nerving, not to mention incredibly arousing.
“Now, now my dear sweet boy. We've just met, you and I. Have you no pleasantries to offer before you ask something of me?"
Her face had an alluring maturity to its features and if she were human
