Succubus Takeover (Reiko)

(1) Reiko was a naive housewife in her early 30s. One night, she had first argument with her husband at the time when he suggested that they should get a divorce. Heartbroken, Reiko ran away out of their home at the middle of night. She didn't know where she was going, but she just wanted to get as far away as she could. When she finally came to her senses, she had been running all the way to the next morning and now was struck in the middle of an unfamiliar forest. Exhausted, she sat down against one of the trees and began dozing off. Little did she knew that she would be targeted by a succubus from hell, who sought to possess her in order to materialize in the world of the living.

(2-5) The succubus transferred her power little by little into Reiko's body, causing her body to heat up and gradually become more voluptuous. Soon, the dark power started emitting from Reiko's body, destroying her clothes and exposing huge and still growing chest. Reiko began to have nightmares as her body temperature continued to rise rapidly. Eventually, Reiko woke up, realizing what was happening to her. She can feel the presence of the succubus trying to take hold of her body, which had already begun adapting to the succubus's own physics, including her crimson hair, her red eyes, and her oversized breasts. What was more, her body temperature was now so high that it was literally cooking her inside out, so much so that the heat and dark energy emitted from her body began to catch flames.

The story branches off from here.

(6-7 Reiko Loses) Reiko tried to resist, but her body was already ready to embrace the succubus as its new owner. Soon, Reiko's face began to morph, becoming the same as the succubus as it successful took over control of her body. Reiko was still conscious, but there was nothing more she could do but watch as her body's transformation is complete. Soon, everything around Reiko began to burn as the succubus flexed her powers. Eventually, Reiko realizes that this particular succubus gains pleasure from burning rather sexual activities. The more thing the succubus burned, the more corrupted her body became. Trapped in her body, Reiko can only watch through the succubus's eyes and hope that no one she knows would come across this vicious demon.

(8-9 Reiko Wins) Despite her body giving in into the succubus's influences, Reiko held firm, desperate not to let the demon give control of her body. Eventually, the succubus got tired of trying to possess her and moved on, leaving Reiko with her already corrupted body. Her body temperature eventually returned to normal as Reiko dozed off once more.

A few months later, Reiko divorced her old husband but, thanks to her new physics, soon found herself married again to a wealthy CEO of a successful firm who was 10 years younger than her. The CEO would take Reiko to meet with many of his business partners, all of whom are amazed by how beautiful she was. Reiko now gets anything she ever wanted and she has never been happier.
