Demonic corruption(main story)

Before Evan could protest, his cock was inside Olivia's mouth, touching the back of her throat as he let out a moan and fell against the floor. He did not have a lot of sexual experience and had never felt anything this good before as she had complete control of his sex organ and felt like she was trying to suck his soul out of his body.

"Fuck........ FUCK!" He yelled as he bucked his hips.

Olivia released his member for a moment, letting the strings of precum and spit drip from her lips as she licked his member. She teased it and chuckled a little as her eyes had a strange yellowish glow to them.

"You like it when I tease your cock, don't you?" She said as she continued. "You've wanted to fuck me since we met, and I am going to fuck the shit out of you, Evan. You're cock is mine now, and I am going to make sure it gets fucking used properly," she said before she deep-throated his cock once more, sucking even harder this time as he squirmed on the floor, unable to escape.

"Olivia....... Jesus....... what...... what's gotten into you?"

She released his member again, and a sadistic smile came over her face. "In me? The only thing in me will be this big fucking cock of yours, but first," she said as she squeezed her huge tits together. "How about I play with these?"

Evan wasn't sure what she meant until he watched his penis disappear between her mounds. She squeezed them together and stroked his cock, giving the tip a few links as it got close to her mouth.

"Are you going to cum for me? I know you want to. You want to cum in my mouth? Or maybe all over my tits?" She said as she continued to stroke his member, letting the spit and precum form a perfect lubricant as she continued. "No, I know exactly where you want to cum," she said with a smile that showed off long fangs sprouting from her teeth.

"Oh God...... Olivia?"

"Don't be scared Evan, this is going to be fun," she said as she sped up her tits, stroking him even harder as he moaned and writhed on the floor. "Don't cum yet though. I need you to hold on for the big finale!"

Evan couldn't believe this was happening but he was a bit frightened. This was not Olivia, and deep down, he knew he needed to stop this. He glanced over and saw her phone on the floor, the screen glowing and the picture of the statue still on the screen as this strange red glowing smoke oozed from it.

"I need to........." he said as he reached for it, despite how badly he wanted to keep fucking Olivia, but as horns sprouted from her head, he knew he had to stop it before it was too late.

"Come on Baby, don't you want me?" She said as she released his cock from her tits and began to crawl up towards him.

Evan grabbed the phone just as Olivia impaled herself down on his member, making him scream his lust before he chucked the phone against the wall, smashing it to pieces. Olivia smiled at him before she seemed to get a little dizzy and collapsed against his chest.

"Olivia?" He said as she struggled to catch her breath.

The horns disappeared before she looked up at him confused. "What....... what happened?" She asked before she realized he was on his cock.
