She continues to change

Calvin felt dizzy as he opened his eyes. He had passed out from that intense orgasm in the living room but now he was somewhere else.

The sun had gone down and he was in the bedroom. He was comfortable for the moment until he realized his wrists were tied to the bed. He tried to pull free but he couldn't get loose.

"Shit, what the fuck?" He said until he heard a voice.

"Just relax Calvin," a voice said from the darkness as he saw two green glowing eyes staring at him from the corner of the room before Cindy stepped into the light. "Now that you're awake, we can continue."

"Cindy, Baby, what's happened to you," he asked as she continued to struggle. "This isn't you, this isn't....... human!"

"What? You don't like the way I look now?" She said, showing off a little, still with the fangs and the ears.

"Cindy, you look..... so fucking sexy. But you have to see that this isn't right. Something is wrong with you, and I...... I want my Cindy back."

"You're Cindy?" She said with a chuckle as she climbed onto the bed. "This Cindy can do so much more," she said before she zapped his penis again with another bolt of green lightning, making him hard again but not making his cock grow abnormally large like before. "I said I want you to fill me, with every drop you have. Cindy gets what she wants!"

Calvin stared at her, his heart racing in his chest as she gently stroked his cock with her fingers. Her eyes looked inhuman, and he was afraid for his life, but this shame came over him because as strange as she looked, and as worried as he was about her, he was also the most aroused he had ever been in his life.

"Shit..... Cindy...... I....."

"Shh," she said placing her finger on his lips. "You are going to enjoy this," she said as she licked her fangs with her lanced tongue before she began licking his chest. "Oh Baby, you are so sexy," she said in that voice that made him feel uncomfortable.

"Cindy," he said pleading that she was still in there.

"What, afraid I'm gonna take your soul?" She said with a grin that sent a chill down his spine as she let his cock rest against her slit. "Wouldn't that be so bad? This pussy can do amazing things, and despite how scared you are, you want me to let your big cock inside me, don't you?" She teased as she rubbed her slit against his member, lifting her hips and letting the tip in just a little. "Even if you died, you'd want to die like that, wouldn't you?"

"Shit...... this is so....." he said as his heart raced.

"Don't worry, everything is going to be okay," she said before she finally impaled herself on his throbbing cock.

"Oh God!" He blurted out, bucking his hips a little.

"Now, you can run if you want," she said before she cut the ropes holding him down with her sharpened fingernails. "Escape, run away, call for help. I won't stop you," she said as she made little circular motions with her hips, gently massaging his cock inside her. "No? You don't want to?" She teased with a smile. "Very well then, I gave you a chance."

Cindy leaned down and licked Calvin's lips before kissing him. She began to move her hips a little harder, milking his cock as his hands slid around her waist. He let out a moan as he knew he couldn't leave, and he didn't want to either.

"That's it, just give in," Cindy said as she ran her hands along his chest and moaned as she moved her hips a little faster. "This feels so fucking good!"

Cindy and a glowing green aura around her as she fucked him. Soon her body began to change again. Horns began to sprout from the top of her head as Calvin looked on in horror, still scared about what was happening to his girlfriend. He then saw something curl around from behind her. It was a long tail attached to her lower back with a spade tip.

"Cindy..... what's happening to you?" He asked.

She was becoming more demonic with every passing moment. Even Wanda could feel this from where she was back at the mansion with Leon and Dawn, all in bed together after having an incredible three-way moments ago.

"Everything alright?" Leon asked as he noticed Wanda was a bit distracted lying next to him, while Dawn was asleep against his chest.

"I turned someone today, well, Henry and I did, and I have never seen a transformation like this one," Wanda said with concern in her eyes.

"What is it?"

"She had been sexually repressed her whole life, for religious reasons, I think. Now she is fully embracing sex but it's turning her into..... I dunno, almost as if her deepest desires are turning her into a sort of sex demon."

"Is she dangerous? Should we do something?" Leon asked as he sat up, trying not to awaken Dawn from her slumber.

"I'm connected to her right now. She's still in there, but I'm worried she may lose control, but I won't let that happen," she said as she entered Cindy's mind, just as an observer for the moment. "Get some sleep, Leon," she said as she gently stroked his face. "I have it under control," she said before she rolled over and got comfortable.

"Sex demons now?" He said to himself as he got comfortable again, putting his arm around Dawn. "Sounds like fun."
