To fuck and fuck some more!

"Fuck me HARDER DADDY!" Caroline wailed, sprawled out on the bed with her father hunched over her and pounding her ass with abandon. The girl turned succubus moaned as her demon of a father pushed his cock further into her backdoor in tandem with his tail in her pussy. Caroline nearly came again, but was pulled back by a hand pushing her head down.

"Cum all you want, slut, just keep using that tongue," Lilith said, forcing the submissive succubus to continue eating her out. Caroline mumbled her assent, tongue pushing deep into the original succubus' slick cunt. "FUCK YES! You're tongue is so good! Here comes your reward, you little whore. I'M CUMMING!!" Lilith yelled, forcing the young demoness' face into her pussy, her nose pressed against Lilith's throbbing clit. "You too, hunk! Fill you daughter's ass with that fucking seed!" Eager to please, Cade did just that, pushing his throbbing dick as far as he could into Caroline's butt, filling her with black cum, his tail doing the same for her pussy.

"Yes, take it, my whore! I should have fucked your tight little cunt and ass ages ago!!" he bellowed, shaking the windows with his booming voice. Caroline could do nothing but thrash and quiver as her body joined in the orgasm, every nerve overloading her mind with pleasure.

Lilith and Cade, their orgasms ended, pushed Caroline away, leaving her sprawled on the bed with cum on her face and dripping out her ass and cunt, still riding out the aftershocks of her own peak. "Mmm, what a good fuck. You really know how to make them," Lilith crooned to Cade, pressing her large boobs against his muscular chest, one of his hands reaching down to grope and squeeze her ass, making the succubus queen giggle and coo. Suddenly, the front door slammed shut and pounding footsteps came up the stairs.

"CADE!! WHERE ARE YOU?! WHAT THE hell..." a voice yelled and trailed off. The three demons turned to see Cade's wife, Nicole, standing in the ruined doorway, staring at her demonized husband and daughter.

"Oh hi Mom," Caroline said in a carefree tone. "Like the new me? Daddy fucked me into a succubus. I don't know why you don't have sex with him more, he's sooooo good at it. Mmm, just thinking about it makes me wet." Nicole was utterly shocked by the words and body of her youngest daughter. Gone was the cute short girl and in her place was a crimson teenage slut.

"Mom, what are you yelling about?" a man's voice said from the hallway, two more figures appearing behind Nicole. Jenny and Bryce, the oldest and middle children respectively, looked at their transformed father and sister, their jaws falling open.

"Hey bro, wanna get your cock milked? I'm really good at it," Caroline said, waving her bouncing ass in his direction. Bryce immediately got a hard on, despite knowing he was looking at his sister.

"You're home just in time," Lilith said, sauntering up to the three human family members. "We were just getting ready for some new company. How about you help us out?" A wave of demonic pheromones washed over them, sending a spike of arousal through them. "Well, how about it?"

"Our daughter was quite the eager slut, Nicole. I even found her masturbating before I fucked her brains out. Now I want to pump that used cunt of yours full of my cum. I'll show you what you get for being such a frigid bitch," Cade rumbled, stroking his new massive dick. Nicole's eyes were locked on it, her knees trembling with desire. Bryce's gaze was fixed on his sister, who was lewdly fucking herself with her own cock tail, making a show of plunging the tip into her drooling cunt repeatedly. Jenny, completely silent so far, was staring at Lilith herself, licking her plump lips.
