Jessica sneered, "About the only thing you can do right now is kill me, and as soon as I return to the Host, the powers will come down on you like you would never believe. You have no options."
Jim grinned, "Never underestimate the human mind. Humans are often willing to do things that even demons would consider off limits." Grabbing Jessica by the back of the head, he forced her to her knees on the floor. Not realizing what was about to happen, she opened her mouth to say something. Jim thrust his cock home, forcing its inhuman length into Jessica's throat. The angel choked in surprise, but Jim knew she was in no danger of suffocating; she didn't need to breathe any more than he did. Jessica's expression turned from one of shock to one of anger as Jim proceeded to rape her mouth. Soon, her glowing eyes flared, and she tried to pull back. Jim took pleasure in watching her cheeks puff out as he filled her mouth with his seed. A small trickle of cum leaked down to her chin as Jim pumped more and more of his essence into Jessica's pure body. Finally, he thrust all the way into her, giving Jessica no choice but to swallow what he gave her.
When Jim finally pulled out of her mouth, Jessica stood up and backed away instantly. Coughing a few times, she looked at Jim with murder in her eyes. Jim stared pointedly at her chest, and as her gaze followed his, she saw a small bump forming on the end of each breast. The skin around the bump began to grow rough and pebbly, and soon two perfectly white nipples capped her breasts. She reached up and brushed one softly, gasping at the sensation. She began rubbing her breasts in earnest, while Jim pushed her back onto the bed. At the demon's touch, Jessica snapped back to awareness. letting go of her breasts, she demanded to know, "What did you just do to me?"
Jim laughed, "I gave myself an option. Soon you will be like Tania out there, transformed into a creature of lust." A dark line crossed Jessica's groin vertically. The line depened until it formed labia separated by a sopping cleft. Jim ran a finger up the slit, stopping to flick Jessica's forming clit. Jessica cried out as sensations alien to her angelic nature bombarded her mind. pulling away, Jessica tried to reach the door. Jim caught her by the waist and rested his member against her new opening.
Crying, Jessica sobbed, "Please, no, don't do this to me. I'll looohhhhh...." Jim pushed into her, reducing the angel to moans and sobs. As his precum leaked into her, the sobs began to lessen, and the changes began to advance. Her wings and hair began to lose their brilliance, dulling to grey. Her breasts began to grow, soon becoming large enough that Jessica could suckle her own tit. As she moaned into her flesh, Jim began pumping faster. Her hair and wings were now jet black, contrasting against her glowing skin. Jim unleashed roar of triumph as he came, filling Jessica with his corruption. Jessica's eyes went wide as the demon's essence filled her, their golden fire quickly turning a deep red. Her hands grew sharp claws, and fangs extended from her mouth. She gritted her teeth as she battled for her mind, new thoughts and desires were making footholds, corrupting her core beliefs and faiths. When he let her free, Jessica knelt before him. Jim could tell she was still trying to resist as she leaned forward and began to clean his cock with her tongue. The last spark of rebellion died in her eyes, and Jessica looked up at him adoringly. Looking much as she had before, but for black hair and wings, claws and fangs, Jessica asked, "What is your bidding, my lord?"
