Demand a sacrifice

"I have heard the call and answered. What is your bargain?" Your voice booms in the room and finally the wannabe-summoners start to react. "WHAT THE FUCK!" The black gal and the guy sceam in unison before both backing further away from the circle. "SHHH! Shut up, I got this under control!" the woman with the glasses hastily says to them before turning her attention back to you. "Ahem! I- We have summoned you hear to do our bidding! Our demands must be followed to the letter..." She appears to be reading from a note. "...And are as follows: a) We deman-" "I asked, what is your bargain, what do you offer to me?" You stop her, causing her to stammer for a while. "I... Er... What? We summoned you!" You give her a blank stare like a disappointed parent and are try not to laugh at the teenagers starting to panic. The girls with glasses starts to go through a book in a hurry, using her phone to bring some light. "Nobody panic! I'll just- There must be something here..."

"First of all..." You get their attention. "There was supposed to be an altar. I don't see one here. Second, I require a sacrifice... I'm not fulfilling wishes out of the goodness of my heart here, am I?" The nerdy blond who has been sitting down so far, gets up on her knees and shouts "I volunteer as a tribute! You may have my virginity lord!" "Jenna no!" the lone guy shouts but you silence him with a gaze. "Very well. As there is no altar, you may instead approach me directly and prove your servitude by worshipping me." You point at your cock and believe that the girl hasn't moved her eyes away from it since you showed up for more than a second at a time. "Jenna... Are you sure you..." the black girl starts but Jenna is not listening and gets into the circle as fast as she can. If the circle had meant anything, her smudging it up with her knees would have been a disaster but as it is, there is no loss. They were lucky that there happened to be daemons in the mortal realm close enough to hear the call. But finding a willing sacrifice like Jenna is well worth this. ...You are still going to humiliate the rest of them for their arrogance and foolishness before you are done though. Before you, Jenna grabs hold of your cock and is astonished that she can barely get her fingers around it. "Sooo thick... I'm sure as hell about this Layla..." She jerks you slowly and starts to kiss your cock all over. "That's it slut... Worship it. Hm... Let's get comfier." You wave your hand and an old recliner in the corner of the room slides to you. You lay back on the recliner and let Jenna work on your cock for a while. She is not particularly talented but she is very enthusiastic, clearly enjoying the taste of your cock. ...Which may be because you had been fucking your family for hours and the cock was still coated in their juices and your cum. Or possibly because you are releasing pheromones with aphrodisiac properties into the room. One or both.

The girl with the glasses approaches you slowly. "Ah- Ahem! May I have your attention?" You lazily gaze over at her while Jenna sucks you off. "You have your... sacrifice. So now, you must do my bidding and grant us powers!" Annoying her and scaring her lackeys is even more entertaining than the amateur blowjob, so you decide to continue edging her. "My sacrifice is not done yet. Not until I have taken her virginity-" Jenna stops for a moment and looks up. She seems is as eager as ever and slowly climbs onto your lap. "-as you can see, we are busy. Either come assist her, or stay silent and wait for your turn." Glasses girl stomps her foot for a while but does not dare to interrupt you. With Jenna sliding her body against yours and measuring the cock, uncertain how far she can fit it into herself, you spy the remaining two humans, still hiding in a corner, but by now they are breathing in your pheromones and staring at you and Jenna, clearly captivated. Rather than just cowering together, their hands have started to wander and the girl is rubbing the bulge on the man's groin while he is groping her ass. Such weak willed humans, they won't be any trouble.

"Bigger than the toys that you've been using?" You ask Jenna and she simply nods. "It's even bigger than the knotted one..." Kinky, you think. You help lift her up and then slowly let her sopping wet pussy sink down onto your cock and engulf it. Jenna starts with a low moan as you fill her, that soon grows louder. "ah... aa... aaah! FFuuuuucck!" You go slow on her. Partially to let her body adjust, but mainly to make a bigger show for the other human. Even the girl in glasses is now sitting down again and biting her lip while staring at how her friend is losing her virginity to an incubus. Jenna hangs onto your shoulders for support and starts to slowly move up and down, whimpering at the feeling. "Good... Do you give yourself to me willingly?" You ask her and she nods, unable to speak. "Do you give your body and soul to me?" "Mmmh..." "I can't hear you... Yes or no?" You tease her and grab her hips, stopping her. She struggles a bit. "YEs... FUCK YES! Anything! Just fuck me you beast!" Even she appears stunned at swearing out loud. You grin and push her down all the way. A human body wouldn't have accommodated that massive cock, but as she is now your sacrifice and your property, her body molds and modifies to better serve as your fuckslut. Jenna's eyes roll back inside her head and her mouth is open in a silent scream. Her friends are the ones to scream instead. "HOLY SHIT!" "DID THAT THING KILL HER?!" "THAT COCK SHOULD BE COMING OUT OF HER MOUTH!" Jenna shows more signs of life though and she grabs onto your chest and cries out in throes of her orgasm. With the foreplay done, you start to fuck into her hard and fast as she is too busy squirming and squirting over you, to participate otherwise.
