Jeff returned to his resting quarters and asked everyone to leave. Why was this happening to him? Why does he have to give up his gender, even temporarily, he had grown attached to it. Jeff spent a few moments sobbing before falling into an uneasy slumber.
Jeff awoke 30 minutes later in pain, his wounds were hot, the room felt cold, he was shivering involuntarily and coated in sweat. Jeff had somehow told his body to reject the demonic presence and somehow it was listening. "No." Jeff weakly mumbled realizing this would mean certain death and his soul was already in Hell.
Grabbing the blankets off the bed he walked to the computer and collapsed into the chair wrapping himself in a cocoon. Since not all demons have accepted the new regime, the rite of exorcism still is in effect, so apparently Jeff is rejecting his new organs... Jeff booted the Chronivac, realizing it is his only hope before his body goes into shock and shuts down, purging his own heart and stomach in the process.
Desperately he clicked through his profile and pulled up his transplanted organs, he changed them from succubi organs to incubi organs and marked to change reality, clicking accept. There was a flash.
"Jeff? Hey how are you feeling?" Jenny came in closing the door behind her. "You didn't seem to take the news that your body is accepting the transplant as well as we expected."
"It's just, different you know." Jeff said reacting to her presence.
"You'll get the hang of this. it might take some time but soon, you'll be able to keep yourself from transforming." Jenny said, desperately resisting the urge to mount Jeff right then and there. "You'll be okay. You are okay."
Jeff was a teenager and used to emotional upheaval but wasn't prepared for the flood of emotions he was now subjected to. She was rejecting him! She left without giving any sexual satisfaction! What did he do wrong? His body shifted from a 16 year old to a 23 year old tattooed version of itself and back again... why doesn't she love me?
No, this was just his new organs playing tricks on him. He can regain control. Succubi can become a variety of creatures and feed on the pleasure felt by all animals, but Incubi prey on humanoids. So their transformations allow them to become any age, ethnicity, or mixture thereof to entice someone into sexual action.
Jeff knew, in a scholarly way, of the incubi, they were rarer than the succubi who preyed on the the much more numerous evil men of the world. Incubi preyed on the evil women of the world, taking the most desirable form and wielding it in a way to dismantle those women.
Where Succubi can become any number of creatures Incubi can take any form of man, old, young, strong, meek, and anything in between. Jeff, having no qualms with demons and no resistance to the transplant was being overwhelmed by the new demonic powers that were emerging.
