Take the stairs and go up

You follow the long stairs and end in the library
Pity, there is no secrets here...
Or so you think

To your surprise, you realize you are on the forbiden section, where all the magical books and secrets are keept. That's where the REAL magic books are stored. The dark and gritty ones, with powerfull spells and summoning. You must have gone up a lot, since it's in a tower, but maybe you're more lost than you thought. Still, this is an opportunity that you never had before...

You can spend some time learning something here, so your search won't be wasted
Or you can get down on those twisted passages and try to find something...
It's not really a choice, is it?

So you sit down and start to read

The time reading is more rewarding than you would have thought at first, for you find a cool tome about demon summoning and it's several methods. It's very forbiden, but you quickly realise how powerful this would be as a tool to take over the throne, and decide to try a simple formula for summoning an imp

It works and you celebrate alone in the dark library, taking care of making no noise

But now what? You don't need a minion, you're a prince. You send the imp back and start to think. To take advantage of this, you would need to act the opposite way of a regular warlock would. Instead of having an army of lesser servants and forcing them to obey by your will and magic, you will need a single powerful servant

Well, not really powerfull... You will lead armies one day, so why would you need power? No, you need one that is smart and clever, capable of disguise and subterfuge. Still, that's a high ranking demon - and with the amount of training you have, the only realistic way to do this is making a pact and being honest about it... or to cheat

You let go an evil smile in the dark and decide to try

Five hours of reading, two spells learned and twenty minutes of incantations later, you summon a greater succubus. Well, kind of... you get the circle wrong on purpose: that way you will get a far weaker succubus than normal AND she will be greatly weakened by the process. Usually no warlock would want that - summoning powerfull demons is the whole point - but to you, that's a feature

In a few moments the succubus shows up

In front of you stand a tall woman, in her 20's to 30's, naked. She has an atlethic body with long legs, a round butt and some perky breasts that her long red hair cover. You notice her slim tail, but her horns aren't visible bellow the hair

-- Well, well, look what we have here... so you are my summoner? - her voice is seductive and low, almost like the groan of an wild animal - What i can do for your pleasure tonight, hummm? And what you're willing to pay for it?
-- No deals today, you will submit to me
-- Demanding, huh? Can you back this up?

She licks her lips and gesture to you get inside of the circle, waiting for you to pull your cock off and fuck her silly... or be drained by her. That's how it goes, right? But you snort and for a moment she looks confused... Then you cast the first spell you learned today: mage hands, and invisible hands made of magic grope her breasts

-- Oh, fuck

Her eyes widen and she push the magic circle, trying to find a weakpoint to escape... but the circle is well made. She can't get out and only now she realizes how weakened she is. Your hands run over her body and she moans loudly, but she can't do anything, not with you six feet away. Still, she tries to cast spells: charm, fireballs, summoning... nothing works, and while she tries you keep gropping and teasing her

-- Aaahhh... i'm soooo wet... come and fuck me - she says opening her legs
But you ignore her

Moaning louder and louder as you slap her ass and fingers her, the succubus finally try to break the circle by brute ****. It fails too and she start to get nervous. She gathers her magic and tries to charm you, making provocative poses and luring you to fuck her, begging for your dick... in response you use one magic hand to squeeze her neck while the other keeps fingering her

It's too much and she starts to break
-- Nooo! Not like this!

The Succubus start to beg, to ask to be fucked by your dick, please... but you ignore her and make her cum with the magic hand. The harder she resist, the more intense she feels when she can't hold it back anymore and the orgasm shakes her entire body

Once she stops squirming you finish the second spell and bound her to yourself. She turns into a shadow and enter your own shadow, now a servant at your orders. Then, and only then, you relax. You sit in a chair, exhausted, and wait until you get yourself back in control. Despite your sassy and flippant behavior, her charms almost got you to enter the circle

Well, now doesn't matter, you just got yourself a nice servant
Now is just a matter of time before you find a nice use to her
You have a feeling this will be important in the future
