Time to bring Jess's family into the fold.

"Oh, yes, Jess," hisses your father, grasping your lover's head. "That's it, you whore! Take my dick down your throat!"

"Fuck, Mom," you groan, as your mother licks your swollen balls, "you swallow my cock like a depraved slut now!" You and your father grunt and cum down the succubi's hot throats, filling their mouths once again with black jism. The four of you have spent the last hour or so enjoying each other in virtually every combination possible. Your mother pulls off your dick and smiles.

"Oh, hell, son, this is so... glorious," she whimpers.

"Just wait until we get to Grove Street," you whisper, stroking her hair. "Dozens of incubi and succubi to fuck... a whole pack of incestuous degenerate Lilin performing the most vile and filthy acts with each other..." Your mother groans in pleasure.

"Hey, lover," says Jess, licking your father's cockhead. "Don't forget we came here to turn my family into sex fiends too!"

You chuckle and give Jess a swat on the ass. "Oh, I haven't, skank. We are going to fuck them into Lilith's image."

Your mother shivers at that. "Let's go get them now!" she says eagerly.

"I'm up for it," says your father, stroking his immense cock.

You and Jess nod at this. "Right," you declare. "Let's go fuck your family, slut."

Jess cackles as she stands, her immense funbags wobbling. "This'll be fun," she chuckles.
