Solo female roleplay. Cathy is content living a very ordinary life until she starts getting mysterious envelopes pushed underneath her door every day. On first opening them, she is shocked to find erotic drawings of monsters and demons, feeling disgusted and fearful - but something changes in Cathy once she's laid eyes on the drawings. She picks up the envelope every day despite her initial apprehension and guilt, and each day it gets easier to look at them... They start to make her feel ways she hasn't felt before. When she looks, it makes her want to touch. She tries to fight it at first, but she's already seen too much - she's possessed by a demon that wants her to get more and more depraved, to give in to her slutty nature. As the days go by, even Cathy's appearance changes, favouring short dresses and seethrough lingerie to her usual conservative dresses, and she starts to look forward to the envelopes. She stops feeling guilty and embraces the feelings, looking at the pictures and touching herself, and playing with vibrators and dildos. As the demon takes over, she starts to find her kinky side, indulging her inner masochist by spanking her pussy, ass and thighs, and fingering herself harder with a ribbed glove. Once a week has passed, the old Cathy is truly gone, with a messy depraved slut left in her place, chained in a collar and leash, drooling all over her dildo, makeup smudged beyond recognition, and her whole body covered in demon cum. Final scene is in mood lighting for a horror theme.
