Everything and everyone.

Dan shoves his cock up his mother's asshole, causing Vivian to scream in pleasure and pain. "Oh, that's it baby, that's it!" She squirms under him, jiggling as she takes her pounding.

Dan snarls and shoves his tail down her throat. "Take it, bitch!" The others snicker at that, and then continue with their rutting. Fathers fuck daughters and sons fuck mothers for awhile, until another wave of climaxes sees partners switch again. And then again. At last, the women of Jess's family all lie together on the floor, shaking their massive tits and succulent booties as the men jerk their gigantic demonic cocks over them. Your mother joins them there, tweaking her hard black nipples.

"Oh, cum all over us!" squeals Lucy.

"Paint us with your seed!" howls Jess.

"Do it boys!" snarls your mother. "Give us that fucking filthy coat!"

With a group of snarls and hoots, you and your incubi brothers climax, covering the delectable succubi before you in inky black jism. They howl in laughter and rub the juices into their scarlet skin, then begin to make out with each other, licking each other clean. Soon you are all watching as the succubi begin to fuck each other, tongues and tails diving down wet cunts and tight assholes. It doesn't take long for your cocks to be hard once again.

"Heh," chuckles Aaron, watching his mother eat out his sister while getting fucked by her own niece. "This is weird. I want to fuck, but I don't want to spoil the show."

"Oh, we can get around that," you say. You move in front of your father, and spread your ass cheeks. "Come on, Daddy. Time to fuck your son again." Your father licks his lips and then shoves his hard dick into your tight hole. Soon the pair of you are energetically bouncing against each other once again, reveling the twisted sensation. You grunt in pleasure as his fleshy length spears deep inside you.

"Fuck!" says Dan, jerking himself off in lust. "That is hot!" His tail coils around Julian's waist as he begins to rub his muscular ass against his father's immense prick. "Come on, daddy! It's time to teach your incubus stud son how to be a real man!" Julian laughs and impales his son with demonic member. The pair kiss feverishly as they couple.

Aaron watches all this intrigued, but clearly processing his new bisexual urges. His father needs no such effort--Ben grabs his son by the waist and effortlessly lifts him up, shoving him against the wall. "Time to take your dad's cock, Aaron," he snarls, shoving his member deep inside his son's asshole. The younger incubus howls in pleasure as he takes his first cock--his own father's.

For a while, you six incubi fuck standing--then your fathers gather around a sofa, and deposit their sons on it, massive demon dicks plunging in and out of tight holes the entire time. You kiss Aaron, serpentine tongue entwining with his, then turn and make out with Dan. Aaron leans in and joins you in a three-way kiss, stroking your dicks as he does so. Your fathers chuckle as they watch their sons rub and kiss each other while taking cocks up their asses--their cocks. And then they pull out. You all give disappointed moans at no longer having your fathers' manmeat pounding your asses, only for another incubus to slide in. Ben fucks Dan's ass, your father takes Aaron's, and Julian's huge prick slides down your tight hole. The three of you howl in pleasure as the three of them use you as queer whores, swapping you amongst themselves. As it ends, each father plunges his own cock into his son once again, shooting his black cum into his boy's tight hole. The three of you gasp in pleasure and climax yourselves, covering each other and the sofa with your juices.

When its over, your fathers regard your debauchery with clear pleasure and approval. As Aaron and Dan make out again, you rise up and grab your father. You twist him around and bend him over, fucking his ass once more, while jerking his dick with your tail. Aaron and Dan watch with interest then join you, grabbing Ben and Julian and then giving them their son's cocks.

"Oh, yes, Dan," gasps Julian. "Fuck daddy! Fuck daddy's hole!"

This session is quick--the three of you return the favor, flooding your fathers' asses with jism and coaxing a climax from their massive cocks. The succubi, watching from the floor, finish their most recent wave of couplings. Jess lazily licks the cum around her mouth. "I think it's time for us to go to Grove Street."

There is a howl of laughter and agreement from all the Lilin.
