Cassie shivered. "I think I...am cursed."
"Cursed? What do you mean?"
"Rachel...I'm incomplete, I'm missing a part of myself. You have to help me." Cassie then moaned softly, one hand reaching down between her legs.
Rachel's eyes widened as her friend began to pleasure herself. This wasn't like Cassie at all! "What can I do, I want to help?"
Cassie's eyes were wild as she looked to Rachel. "Come closer."
Despite herself, Rachel sat on the bed. "Okay...what now?"
Cassie lunged at Rachel, grabbing the other girl with inhuman quickness. Despite being taller than Cassie, she couldn't break out of the girl's grip. One hand went over Rachel's mouth...it was the same hand that Cassie had used to rub her crotch, and her nose was assaulted by the strong, musky scent of the other girl.
It wasn't an unpleasant smell, and Rachel felt her struggles weaken until she went limp, completely docile in her friend's embrace.
"I'm sorry, but I need you. I need you to complete me...to complete us. Transform or Dare?"
Rachel was unable to answer.
"I know, it's cheating, but soon love, soon we'll be happy. I dare you to be completely submissive to me; you have no thoughts but my thoughts. Your actions are my actions."
A silly little grin formed on Rachel's face. She would do anything her mistress demanded. Her only pleasure was serving her. She felt a kiss on her neck, and her muscles went liquid with pleasure.
"And now, the transformation. Your flesh will become my flesh, and our body will be whole."
Both girls moaned with ecstasy as their flesh became liquid, and their bodies merged. Rachel's clothing was destroyed in the process, but she no longer cared. Cassie's body began to shrink, while extra mass and muscle was added to Rachel's form. Rachel's light tan and Cassie's pale tone flowed into each other, until all their skin was the same healthy, unblemished color.
Cassie's legs vanished as their mass and muscle was added to Rachel, whose head retreated into her torso. Within moments, the transformation was complete, with Cassie's waist and torso projecting out from where Rachel's neck and head once were, not unlike some twisted variation of a centaur.
Cassie's mouth opened, and she spoke, but with two voices instead of one. "We are reborn!"
She had been cursed to become a creature known as an erodaemon, a temptress forever forced to crawl on the hands and knees of her lower body, the physical embodiment of the dark, twisted lusts hidden in the hearts of men and women. But to complete her metamorphosis, she needed another girl.
She chose the one person who was closest to her heart and soul, and now they were one. The daemoness stretched, even as she surveyed her form. Despite her freakish configuration, she was beautiful, and none would be able to resist her. Her powers were growing by the second, even as she was filled with a lust that could never be sated.
Crawling on her lower body, the daemoness got off the bed. There wasn't much point to clothing herself; she could ill-disguise her bizarre nature, nor did the elements cause her any discomfort. Instead, she began to search for her first victim.
The last vestige of her mortal morality refused to allow her to remain and prey upon Cassie's former family, so she slunk out into the back yard. Though she now possessed inhuman strength and grace, she was a slow-moving predator, forced to slink up on her prey.
She would need to rename herself, as she was neither Cassie nor Rachel any longer, but a fusion of both. As crept up towards the house behind Cassie's, she decided on Cassriel.
She smiled. Yes, that would do nicely. And then, she spied her first victim.
