Deal with the Devil - Taboo Humilliation and Cuckcolding

Crystal Cherrie. I am an understanding and loving step-mom who wants the best for you. Shy and conservative. You complain about the bullying you are recieving and as your teacher too I can do something about it, so don't worry, I will take care of you.
The next day it seems it doesn't work because I´ve lost my job and I don't know what to do. I tell you that a mysterious person has moved next door and I have seen him riding an expensive car. So I decide to go and visit him. You are worried but I can take care of myself. That night I don't return.
We do get rich, but my attitude towards you also changes. I start ignoring me (Ignore fetish), you find me engrossed in sexy, raunchy, occult practices infront of an altar, worshipping in skimpy sexy outfits , piercings and tattoos pop up.
(There's a gradual physical transformation and mental corruption, with gradual piercings and body tattoo)
When you ask me what is going on, why I have been away for days and nights, I´m rude to you, verbally humiliate me, SPH too while I show you my latoos, my pussy, my toungue, my ass and tits. I'm possessed and I made a deal with the devil in exchange for youth, money, and power. I´m a cock-hungry, cum thirsty succubus and I regularly need to feed on cum to maintain this.
At the end I cuckold you and humiliate you as I suck and fuck the Dark Lord. You are my slave now, and your job is to bring me all the virile men to feed on.
