His daughter doesn't stand a chance

"Fuck yes," Cade rumbled, stomping his way upstairs, Lilith close behind. "That cunt's going to be mine." He stalked down the short hallway before reaching his daughter, Caroline's, room. The door was closed, but that didn't stop Cade. He smashed through it, reducing the wood to splinters. A scream drew his attention and his eyes alighted on his young 18-year-old daughter.

He had always thought of Caroline as a good girl by his old standards, but what he saw now made him reconsider. The small brunette's pants were around her legs, her average ass and bare pussy exposed. Her face was flushed and clear fluid covered her hand. On her desk, her laptop was open to a porn video, depicting a couple fucking with abandon. Cade snorted at the video.

"How fake, she's not even feeling anything. Don't worry, you won't have to fake any orgasms," he said, looking from the laptop to his daughter, who was staring at him in shock.

"D-dad? Is that you? What the hell happened to you?!" she screamed, hurriedly covering herself with her wet hands.

"Hell indeed!" Cade laughed. "I'm just embracing my desires! And right now, I want to **** that tight teen cunt!" He jumped at her, cock throbbing powerfully at the thought of filling her.

"N-NO! YOU CAN'T! DADDY, NO!!" Screaming, Caroline tried to duck out of his reach, but her incubus father was too quick. He grabbed her easily and pushed her against the wall, ignoring her struggle to free herself from his overpowering grip. With fiendish deliberation, he traced down his daughter's shirt with a sharp nail, easily splitting the fabric and the small bra underneath. Caroline's small A tits revealed themselves with barely a bounce, leaving her naked from the thighs up.

"Such a petite little girl," her father growled, fingers pinching at her small nipples, making her squeak with discomfort. He trailed his hand down to her equally small hips and pushed at her wet folds. Slipping a finger inside, he grinned. "Yesss, just as tight as I hoped. I bet you've never even taken a cock before, huh? Don't worry, baby girl, I'll change that." He pulled his finger out of her and **** it into her mouth. "Taste yourself, slut. You're all wet for your father's big demon cock. Now moan like a whore as I fuck you full."

Caroline couldn't help but gasp and groan as her father's cock pierced her folds. She could feel herself lubricating him, her body stuck between the orgasm she had been encouraging before he had burst in and a sudden, overwhelming desire for dick. Her tongue flickered over his finger, tasting her own arousal. Her eyes rolled back as her father roughly pulled himself back and abruptly filled her again. Her body was screaming with pleasure as her mind tried to resist the seductive nature of her demonic father, insisting it was wrong even as her cunt clenched around his huge length. She couldn't focus, much less support herself against the wall, leaving her to hang bonelessly as her father fucked her.

Cade couldn't care less, his simple demonic brain focusing on the pleasure and nothing else. He wanted to cum, could feel it boiling in his heavy testicles, but couldn't, not yet. He was going to get the most out of his daughter and had no intention of ending it early. Instead, he railed into her harder, pushing even deeper into her formerly virgin pussy, delighting at how tight she was, nothing like his wife had been, even before they had been married. Her entire body shook on his length, her mind fighting the pleasure she was feeling.

"Just give in," Lilith whispered in the teenager's ear, licking at the girl's neck and flicking a hard nipple. "You could have so much. You think this is pleasure, wait until you fuck a man to orgasm with your tits. Until men cum at a single look at your body. Their cum feels so good, and tastes divine. You could have it. I know you want to. You want to be that woman in the video, cumming and jiggling around a fat cock." Her words wormed their way into poor Caroline's overwhelmed mind, temptation growing with ever thrust of her father's demonic dick. "Give up that innocence, it won't do you any good anymore. Just...cum," Lilith said, reaching down and squeezing Cade's balls. The pressure was all it took to make the incubus climax. Letting out a yell of pleasure, he pushed all of himself into his daughter, the tip of his cock pushing through her cervix and letting his cum spray out into her untouched womb.

Caroline halfheartedly jerked, the heat of her father's black cum filling her core and throwing her mind into further disarray. "Come now, you can't resist it. You're already ruined, you let your own father spray his seed in you," Lilith continued to whisper, every word chipping down the last of the 18-year-old's resistance. "His dick feels so good, pumping you full, doesn't it? I was like you, I resisted. But now I know. There's nothing left for you but to embrace it. Be the slut you are. You can have as much cock as you want, be fucked stupid, have men worship you. Just give in."

Lilith's words cut through Caroline's haze, giving her a moment of clarity. The heat of her father's cum burned in her, his cock filling her with one last burst before it stopped pulsing. She already missed it, she realized. She wanted more. His dick made her feel so good, like she didn't need to think so long as there was something filling her cunt. His boiling cum felt incredible inside her, and she wondered what it tasted like. Another wave of pleasure cascaded through her body, her every nerve on the edge of orgasm. She needed it, needed to climax or she would go insane. **** to cum, she gave in.

Caroline's limp legs wrapped around her father's hips, pushing herself down on his iron hard member and giving her the last jolt she needed. Her mind collapsed as a shattering orgasm ripped through her, forcing a piercing scream from her throat. All traces of resistance disappeared and the virus started its work. Her gyrating belly became toned with new muscles, ensuring she could fuck herself and anyone else from any angle. Her skin turned red, starting at her belly button and spreading outward. Teenage hips widened and her ass pushed out, forcing her back to arch against the wall as it became a sexy bubble butt. The wave of reddening skin crawled up her torso and breasts, which were far from the A-cups they had been before. With every jolt of Caroline's orgasm, the twin orbs grew a little more, bouncing and shaking with every twitch, until they were mountainous F-cups on her slim frame. The spread of crimson flesh continued up her neck until it enveloped her face, covering every inch of her. Her hair darkened until it was flowing sheet of onyx, her eyes pools of lust. With a final throaty moan, the virus overran her mind and her transformation into a succubus was finished.
