Kate works out her daddy issues.

Hannah Mars swiftly leads you back to an ornate door, and presses an intercom button. "Reverend," she says, and you can feel the resentment in her voice, of having to treat her own husband as if he was her employer. "It's me. Kate's here. Our daughter."

There is a moment of delay, and then Joshua Mars speaks. "Well, come in, Hannah." His voice is hurried, and breathless. The door is opened by an attractive young redhead, whose conservative but form-fitting blouse has clearly been rather hastily rebuttoned. As she darts out, you see Joshua standing in the corner of his richly furnished office, clearly adjusting his pants. Hannah's nostrils flare, but she keeps herself composed.

Kate however does not. Your succubus sister sees her chance, and she takes it. "Damn it, dad!" she hisses as the door closes. "How could you?"

"Language, dear," mutters Hannah.

"I am your father," begins Joshua, turning around, "and I will not be disrespected this way..."

Kate strides up to him, poking him in the stomach. "Come on, dad! Julie's only a little older than me! She tutored me in math! And you're fucking her!"

"Language..." mutters Hannah.

"I bet that's part of attraction!" snarls Kate, as her father tries to come up with a response. "I bet it makes you hard, imagining she's me..." She lowers her hand to Joshua's crotch. "You want to fuck me, daddy?" As Joshua tries to figure out what's happening, you grab Hannah, who seems about as shocked as her husband. Kate effortlessly fishes her father's cock out of his pants, and begins to jerk it.

"Kate..." protests Joshua weakly.

"Don't pretend you don't want this, daddy," coos Kate, swallowing his cock. She bobs her head up and down a few times as her father groans, then pulls away to smile at it. "I've seen you look at me."

"Oh, oh, fuck, Kate," groans Reverend Mars, grabbing her head to **** it back down on his cock. It's clear that it hasn't taken much for the Strain to get him. Hannah whimpers as she watches this incestuous debauchery. To your surprise and delight, you feel her nipples harden underneath her blouse. You grind your cock into her ass, and feel her grind back.

"Shit, Mrs. Mars," you drawl. "You're just a kinky bitch, aren't you?"

Hannah whimpers again, and manages a nod. You snicker and glance at Kate, once again eagerly deepthroating her father's dick. "Man, your parents are a couple of freaks Kate."

Joshua's dick comes out of his daughter's mouth with a pop, and she grins at him. "Mmmm, not gonna say it's a surprise." She glances at Hannah. "So, Mom, you want watch your husband fuck your daughter?"

"Yes," groans Hannah. "Oh, God, yes..."

You snicker to yourself. If this is what Hannah is like without being infected, you can't wait to see what a kinky bitch she is with the Strain in her. Kate meanwhile turns around and hitches up her skirt, revealing her bubble butt and pussy to her father. "Come on, dad," she hisses. "You heard Mom. Pound your little girl's tight cunt."

Joshua groans, and slides his cock into Kate. Hannah gives a moan as she watches. You pull her in for a kiss, and begin to tear off her clothing. "Hannah, you're a bad, bad girl," you taunt. "And so I'm going to fuck you like a bitch." Hannah gives a delighted whimper as you fondle her tits.

Joshua, balls deep in his daughter, leers over at his wife. "Do it! Make that dirty whore scream!"

You lean Hannah over so that she faces Kate, and then slide your cock into her. Soon mother and daughter are making out as their pussies are pounded. You and Kate grin at each other, and then drop your glamours. The Marses groan in delight as your true oversexed diabolic forms are revealed.

"Oh, yes," grunts Hannah as your cock reaches even deeper in her. "Fuck me with that... hellish cock! Make me a perfect whore!"

Joshua howls as Kate squeezes his cock. "Yeah, that's it! Take Daddy's dick, Kate! Take his dick, take his soul, and make him a fucking damned stud!"

Kate sneers at her father, then arches her tail and stabs into his asshole. Joshua gives a grunt of surprise, but soon is groaning in delight at the anal invasion. Kate rears up and pulls Hannah to her tits, feeding her mother her tainted black milk. "Yes! Yes, you degenerate FUCKS! Give your daughter your souls! Give her your souls and prepare to accept the gift of Lilith!"

Joshua groans and cums in Kate, while Hannah climaxes as you shoot your tainted seed into her. As you watch, the pair transform, taking on the dark red skin, black hair and perfect forms of the Lilin. "Ohhh, baby," groans Hannah as her wings, horn and tail emerge. "You've been such a good little girl!" You fondle her expanding tits, and cum into her again.

The now hulking incubus that was Joshua Mars yanks Kate's hair. "You mean a bad little slut," he hisses, as Kate grins at the ****.

"Same thing," says Hannah, licking her lips with her serpentine tongue.
