Lay down some ground rules first...

“First tell me your name” you tell the stunning creature within your spell circle.

“I am Elenor of Tracsor.” she replied smoothly, her lips turned up in an expectant smile.

You had studied enough summing magic to know the tricks of otherworldly creatures and especially of those from the nether-hells. You had also learned the power of true names.

“Do you think me a fool?!” you respond, your voice ringing with command “Tell me your true name, do not make me ask you thrice.”

The creatures smile faded and she bowed her head in defeat.

“I am Eisheth my lord.” She responded meekly.

“Eisheth…” you respond with a triumphant tone “I command you by your true name to obey me in all things and not to hinder or coerce me in any fashion.”

She only nodded her head in submission. With a sweep of your foot you break the circle releasing her into your power. Her dark eyes snapped up to meet yours eagerly but she didn’t move from her kneeling position. The sight of her naked form was too much for you to bear, too many nights had been spent in vigilant study and now you felt it was time to reap the rewards of your toil.

“Do you like the vessel chosen for you Eisheth?” you asked softly.

“Yes master, it is most befitting for one of my kind.” She replied in a low melodious tone free of the harpy shrillness you had heard earlier.

“Then use it to please me!” you command forcefully letting your own grey robes to fall from your shoulders revealing your nakedness beneath.

Eisheth approached slowly, her movements graceful and serpentine, until her naked body was pressed up against your own. You revel in the feel of her soft breasts against your chest and smile as she slides a slender hand down to your throbbing cock. Her whole body seems to be radiating heat and you can feel yourself sweating as she hooks one long smooth leg behind your left thigh molding her naked form against yours.

“It has been a long time since one of the School of Lust has summoned any of my kindred to the surface world.” She said her voice a deep purr “We had begun to think you had forgotten your most devoted of all your servants…”

Her hand ran over your rigid cock in long smooth strokes as she continued to whisper in you ear, her hot breath quickening along side of your own.

“…or could it be that the jealous Council of Masters finally succeeded in outlawing the practice of lust sorcery, they were ever envious of Lust Sorcerers and their magiks….”

Her body had begun to writhe slowly against yours, her hot skin slick with your sweat, her hand moving faster now…

“…but if so, how did one as young and talented as you learnt the craft I wonder? Could it be that…”

With a grunt you pushed her away from you;

“Shut up! If I had wanted to hear your honeyed words than I would have asked for them, bend over creature. I will take what I want!”

You see a flash of intense frustration cross her face but before you can properly register it is replaced with a servile smile. Wordlessly she turned, spread her legs and bent at the waist, easily placing her head between her knees and looking back up at you as her hair sweeps the cold stone floor. Her ass was firm and round and her pussy lips puckered invitingly, grabbing your solid tool in your hand you stepped up behind her and slid the mushroom head into her. Then grabbing her hips you plunged yourself completely into her hot moist depths in a single stroke.

“Fuck that’s what I’ve needed!” You growl as Eisheths body quivered under your hold.

Her snatch was tight and hot, almost unbearably so, but something else was happening, it was rippling and massaging your ivory hardness as if it had a life of its own. The feeling is so intense that you almost cum straight away but with an effort you managed to restrain yourself and grabbed her hair pulling her up straight again, your cock still pulsing inside her and your hips thrusting madly up into her.

Reaching around her torso you grab a gloriously swollen DD tit in each hand and begin groping them frantically, pinching at the nipples and sinking your fingers into the soft burning flesh. The succubus lets out a gasp then a throaty chuckle but otherwise remains silent as commanded.

Her own hips move back to meet your upward thrusts and she grinds her delicious ass into your pelvis each time you bury yourself completely within her hot cunt. The action drives you over the edge and you blast a torrent of cum straight into her super-heated womb. A loud gasp escapes her lips then another chuckle as she presses her slender curvaceous form back against your body.

Her hands reach back and tangle in your hair before moving down to caress your neck and shoulders as she shudders against you in pleasure. Panting mildly you unceremoniously pull your cock from her then sprawl in a chair looking back at her gorgeous form speculatively.

She pirouettes about easily, arches her superb body in delight and gives you a grin that puts you in mind of a cat with a belly full of cream. You scowl back at her mistrustfully, now your immediate needs are met, caution returning.

“And what am I to do with you now?” You ask rhetorically. She just smiles at you until you nod at her to speak.

“There is no end to the amount of fun we could have master! I can be a great help in many different ways and I also possess much knowledge, both of this world and of the nether-hells from which I came. Just ask and I shall answer, command and I shall do!”
