Not long.

The feeling of Jess's cunt around your hard member is amazing--if she hadn't sucked you off first, you'd probably be coming right now. Not that climaxing would stop you from fucking... Jess has clearly infected you with enough of the Lilith Strain to keep you going through half-a-dozen orgasms. As she jerks up and down on your cock, you watch as her enormous boobs bounce, the black nipples hard. Jess grasps your head and pulls to her breast. "That's it, stud," she whispers. "Lick it." You follow the instructions, so crazed with lust that the thought of doing otherwise never occurs to you, your tongue running up the side of your demonic lover's breast, until it reaches the nipple. As it runs over the fleshy nub, a drop of sweet black cream leaks out. One taste and you're hooked, suckling on Jess's breast like a child. She chuckles and guides your hands to her shapely rear. Soon, you're massaging the plush cheeks, reveling in the feel of the velvety smooth skin.

As you suck her tainted milk and feel her tight cunt pull on your cock, the cries of Amanda and her father echo in your ears. "Fuck! Yes, that's it! Pound that filthy pussy, Dad! Make your slutty whore daughter cum, like the bitch she is!"

"Oh, you little cunt! You sleazy fucking tramp! Squeeze Daddy's dick with your fuckhole! Yes, just like that! ARRRRGH!"

"AHHHHH! OOOOH! DADDY! YES! YES! YESSSSSS!!!"

Jess bounces on your lap. "Yeah, you like the sound of that, lover, don't you? It's okay. Just relax. Let yourself go. Come for me, babe. Give it to me. Give it all to me..."

With a cry you climax into her infernal cunt, giving Jess your seed and your soul. Your cock swells and then it keeps swelling, growing to enormous size inside her. You feel yourself filled with an unholy strength, muscles growing--you lift yourself up off the ground, effortlessly carrying Jess with you. "Oh, yeah, that's it, stud! That's it! OHHHHHH! You're feeling it now, aren't you?"

You snarl at that, carry her to the hood of your car, and begin to pound her like the dirty whore she so clearly is. You feel your body swell with power, your flesh tear and reform as your horns, wings and tail appear. As your heavy, swollen balls slap into Jess's delicious bubble-butt, you harshly squeeze her breasts, producing a gasp of pleasure from her. "Oh, yeah, lover. Use me! Use me like the slut I am..."

"You fucking crazy cheap demon skank!" you snarl. You feel her tail wrap around yours, and jerk it slowly. The pleasure is immense. You respond by having it jerk hers back, producing a whimper from your lover.

"That's right!" Jess growls back at you. "I'm a depraved nympho bitch! A cheap skanky hellwhore! Flood my filthy twat with your dirty cum! I NEED IT! DO IT!"

You grunt and cum again, fountaining your tainted jism into her hellish hole. As this happens, both your tails twist together shoot out that inky black cum, covering the ground and filling the air with the arousing scent of demonic rutting. Jess pulls you in for a kiss. The pair of you make out savagely, tongues twisting against each other.

"Fuck why did I run?" you ask when you finally break the kiss.

"Welcome to the winning side, lover," says Jess with a smirk. "It's fucking awesome."

"Damn right it is," comes a familiar voice behind you. "Praise Lilith!" You and Jess turn to see the incubus--other incubus now, really--with his daughter hanging on his arm like a cheap slutty escort. They smile at you, eyeing the pair of you like pieces of meat. You and Jess return the favor. You regard Amanda's now voluptuous curves and demonic beauty favorably, and find yourself looking at her father's tight form and immense prick with interest in well. You suspect you and Jess will both be exploring your newly-acquired bisexuality in the near future. The incubus offers his hand. "Robert Jennings," he says. "And this lovely little slut..." he adds, slapping his daughter in the ass, "is my daughter Amanda."

Amanda rolls her eyes at that. "Ohh, daddy," she titters. "I'm sure they heard you say my name when you were fucking me like a trashy slut."

Robert chuckles at that. "No reason not to be polite, you little fucking whore," he says cheerily. He pulls her in for a kiss, and you watch the pair make out passionately. Something tells you that you're both going to like the Jennings.
