Some fun for the whole family.

Your father screws your mother urgently, less like she's his beloved wife, and more like she's a degenerate whore who needs to be treated like a piece of meat. Which of course is the case. She howls and spurs him on while Jess strokes your cock.

"Yes, harder, faster!" she screams, playing with her leaking tits as she bucks her hips to meet his pounding. "Treat me like the filth I am!"

"Ohhh, fuck, Linda," he groans. "You feel so good now!"

"Better than I did as a mortal?" she says with a lustful sneer.

"So much better!" he howls. You and Jess cackle at that. "You're such a better fuck now!"

"Yeah, this is what you really wanted, isn't it, hon?" she husks. "Some cheap whore who will take your cock like a pro!" He groans and nods. "Endless raw nasty fucking!"

"Oh, fuck, fuck yes," he agrees.

She rests her legs on his shoulders and sneers. "This is everything you ever wanted, isn't it, Scott?"

Scott nods weakly. "Ever... everything..."

You cackle and come up behind your father, rubbing his pumping ass with your hands. "Oh, I don't think it's everything, dad," you note. "That's coming up." You swiftly spread his ass cheeks and then **** your cock into his ass. He howls as you hilt into him, pausing briefly in his animalistic fucking of your mother. But it is clear the Strain has him now--being sodomized by the massive demonic dick of his own son is only another degenerate delight. Soon he is screaming in pleasure as he fucks his wife's fiendishly tight pussy while taking his son's immense cock up his ass.

"Yeah, yeah, that's it, Scott," snarls your mother. "Take our boy's dick up your ass! He's so good, isn't he? It's only right that he takes his parents' anal cherries!"

"Yes, yes!" screams your father, alternating between driving his cock up your mother's cunt and his ass onto your dick. "Fuck me son! Fuck me while I screw your mother's dirty whore pussy! AHHHH! FUCK! YES!" The three of you swiftly reach a feverish pace in your fucking, your flesh slapping against each other constantly.

"Oh, fuck I want a part of this!" snarls Jess leaping up onto the table. She squats on your mother and grabs your father's head, pushing it to her crotch. "Eat that demonic cunt, Scott! Eat it!" Your father does so with gusto, even as your mother clutches Jess's ass and plunges her tongue down that hole. As the four of you fuck, the table at last gives way, collapsing onto the floor--you are all so lost in fucklust that it barely registers, continuing in your hellish rut.

With a few more thrusts you all cum together, your father having his last mortal climax as his cock and face are covered by the hellish fluids of your mother and Jess and his asshole filled by your inky black cum. The three of you devour his soul and watch as he rapidly becomes another hulking incubus, crimson-skinnned, with a muscular stud body. Your mother howls as his cock enlarges in her, while you groan as his asshole squeezes your dick with a newfound skill. Jess clutches his newly-sprouted horns and grinds her pussy into his face. Soon the four of you are all fucking again, as your father joins in with the strength of the damned. You all reach another climax, covering the dining room floor with your inky black fluids, and then pull apart.

Your father licks his now youthful face clean of Jess's juices. "Well, that's something new for game night," he chuckles.

"It's wonderful, isn't it, Scott?" says your mother. "Mistress Lilith has brought us closer than ever."

"Fucking right," he agrees, than turns and kisses you. You and your father make out, stroking each other's hardening dicks as Jess and your mother hoot their encouragement. Suddenly your father grabs you and flips you over, exposing your ass. You feel him grind his cock between your ass cheeks before stabbing it into your asshole.

"Ohhhh, fuck!" you groan.

"Yeah, that's it, son," snarls your father as he begins to fuck you. "Time for you to fucking learn that turnabout is fair play!"
