The Oakses accept Lilith as their personal damnation.

"Oh, oh, fuck, Hannah," grunts Samuel, as he plunges in and out of his daughter. "I love fucking you so fucking much. Why didn't we do this before?"

Hannah chuckles as she hears these words from her father, proof of how far he has fallen to the Strain. ****, adultery and sinful debauchery no longer shock him, but instead excite him. "Well, that's easy, Daddy," she coos, letting her glamour drop. "We didn't have Lilith to show us the way before."

Samuel and Ruth stare in awe at Hannah's succubus form, with its blood red skin, batlike wings, and even more exaggerated curves. "Oh, FUCK," grunts her mother, moving to embrace her damned daughter. "You're even sexier now, babe!"

Hannah slides her tit into her mother's mouth, giving the woman a taste of her tainted milk. "Oh, I'm more than that, Mommy," she coos, sliding her tail into her mother's twat. Ruth's face goes wide.

"Oooooh, you're fucking me," she groans. "My daughter is fucking me! She's screwing my tight, slutty cunny! Ahhhhh!"

Samuel leers at his wife. "She making you feel good, Ruth?"

"Oh, so good, Sam," moans Ruth. She licked her lips at her husband. "How do you like your daughter's filthy pussy?"

"It's soooo tight, Ruth," grunted Samuel. "Sooo wet."

Hannah snickered. "You're gonna get a chance to feel it soon, Mom." She looked at her parents. "But come on. Just do one little thing... one little thing... and I'll take your souls. And then you can really start enjoying this filth."

Samuel and Ruth groaned. "What... what do you want...?" muttered Samuel.

"Renounce God," spat out Hannah, "and pledge yourselves to Lilith."

Her parents are silent for a second... but only a second. A thing that would have been inconceivable to them only moments ago now seems simple and obvious. "Ohhh, fuck God! Hail Lilith!" screams Ruth. "This is what I want now! To be fucked like a slut in all my holes!"

"That's right! That's right!" shouts Samuel. "Fuck chastity! Fuck faithfulness! Let women be sluts! Let men be studs! Let adultery, **** and debauchery spread over the world! Fuck God and all his commandments! Let the age of Lilith begin!"

The father and mother climax together from their daughter's diabolic ministrations. And then their formerly pious souls are forfeit, and they begin their transformation into Lilin. The years melt off them, their forms gaining the hellish perfection of their kind, as their skin darkens to blood-red, and their horns, tails and wings sprout. Ruth plays with her mammoth new breasts, watching with pleasure as the inky milk of a succubus drips from her nipples.

"Mmmm, you look sooo hot, Mommy," coos Hannah. "And Daddy's cock is soooo big now..."

"Can't wait to share it with you, dear," says Ruth, moving in for a degenerate kiss, their serpentine tongues entwining.

"My sweet whores," growls the incubus that once was Samuel Oaks, as he continues to pump his daughter's tight cunt with his now immense dick.

"Ooooh, Daddy," groans Hannah, throwing her head back in pleasure.

Ruth smiles at the degenerate sight. "Fuck me with that giant prick once you're done with our daughter, stud." Samuel grins at her and fucks Hannah harder.
