Summoning a Succubus

Custom video- You sit in a summoning circle with your arms bound behind your back and a strange device tied to your leg pressed against your pussy. You are very haughty and demand to know why such poor excuse for a wizard as myself has summoned you. He tells you he has long desired a succubus servant to serve his every desires. You scoff at the notion that you would ever be the servant of such a pathetic creature. You demand to be let go at once and if you aren't you will make him wish he had never been born the second you break free of these pitiful restraints. He is unconcerned and asks if you know the rule when one summons a succubus. Offended by his arrogance you tell him you of course know the rules. If a succubus cums while bound she will become the eternal servant of the wizard who bound her. You're not concerned though, looking at the so called "wizard" in front of you these bindings won't last long and there's no way he could make you cum. He ask you when the last time you were on earth was and you tell him it hasn't been that long only about 300 years, 400 tops, why would that even matter. Unfortunately for you humans have made some advancements in that time and he turns on the vibrator tied to your leg. The sensation is incredible and you realize you might actually be in trouble here. You squirm and hold out with all your strength but the infernal device is too much. You begin to realize you are in some real peril here and try to find a way out of it first threatening him to release you. When that fails you try to bargain with him, telling him he can have the most beautiful women on earth as his brides if he only releases you, but this too falls on deaf ears. You even offer your own body to him tempting him with a night of unimaginable passion and pleasure but still the device buzzes away. As you reach the edge of your climax you even resort to begging but it is no use. The vibrations soon overwhelm you and you cum uncontrollably. Coming down from your orgasm the spell overtakes you and as you recover from your post cum daze you gaze up at your new Master asking how you may serve him. He releases you from your restraints and orders you to get on his bed and spread your legs. You joyfully agree as he strip and lines his cock up to your pussy. You beg him to fuck you, to claim you completely and he am all too happy to oblige. He fucks you (dildo) as you moan and squeal in pleasure, so ecstatic to be a servant now, until you cum once again and he shoot his seed deep inside you. As you lie there in the afterglow you thank your Master for claiming you and you tell him you can't wait to serve him further.
