The pair of spares.

Derek pounces, knocking the baseball bat from Maya's hands as he grabs her. Mick, meanwhile, leaps at Megan as the teen girl is distracted by Derek's attack. However, her friend Jake shoves her aside at the last second, as the incubus slams into him instead.

Scrambling to her feet, Megan quickly runs over to her sister. The two siblings hold each other protectively and watch in terror as the wicked incubi that used to be Derek and Mick attack their remaining human friends.

Maya and Jake struggle in the the grasp of the two musclebound incubi as they drag their two new playthings over to you and Kristen, who you continue to plow into ruthlessly while watching the spectacle being put on by your incubus brothers. Breaking off from your ruthless fucking, you and Kristen stride over to the struggling humans and shred off their remaining clothes.

Maya continues to struggle in Derek's grasp, muscles straining on her crossfit girl's athletic physique as loose strands of her sweat-drenched black hair fall into her face. The incubus teasingly slides his engorged demon cock between her legs, the length of his throbbing shaft tantalizingly gliding along her pussy lips.

"Come on Derek, snap out of it man! This isn't you!" Maya pleads with her demonized friend.

"Don't bother, bitch. Your foolish little friend is gone forever. I'm one of Mistress Lilith's magnificent fuckbeasts now. Don't worry, though. Once we turn you into a shameless demon whore, you'll see how glorious it is yourself!" the evil incubus taunts his friend-turned-prey as he finally begins to part her quivering pussy lips with the head of his mighty demon cock.

Meanwhile, Kristen tauntingly rubs her new sinful figure against Jake's naked, athletic form while teasing his impressive involuntary erection with a smooth clawed hand. "What's the matter, Jake? Don't you still want to fuck me?" the succubus teases her human friend in a husky, seductive voice far removed from her sheepish and demure human speech. The well built bronzed teen looks at his transformed friend with a mixture of horror and lust at her luscious new curves and kinky, aggressive new personality. "Well, I definitely want to fuck you. But the thing is, so does my new friend Mick over here. And I really want to see him do it!"

"What?!" Jake cries out in alarm.

"Oh, come on Jake, don't you want to make me wet before I ride you?" Kristen taunts him before beckoning her incubus comrade Mick with a wicked gaze.

With an evil smirk, Mick hilts himself in Jake's exposed asshole, eliciting a pained yelp from the violated teen. Mick lays down in a nearby leather armchair, pulling Jake down with him, the incubus grinding his musclebound physique against Jake's well-built athletic figure as the teen squirms on his lap. Kristen, in turn, steps in front of the armchair and sinks between Mick and Jake's spread open legs and she eagerly works Jake's bouncing cock with her mouth and tongue.

After a few minutes, the naughty teen succubus rises up and straddles Jake's lap, eagerly mounting him with her devilish hot cunt as she leans forward and gives the teen a hungry tongue-filled kiss. Just as Jake seems to give in to his lust and return the succubus' kiss, the hellish whore breaks off her kiss with him and locks her black lips with the incubus Mick.

Finally giving in to the infection, Jake wraps his well-toned arms around Kristen's waist and eagerly grabs her juicy bouncing ass, throwing his head back and howling in pleasure at the sensation of the succubus riding his straining cock as he in turn bounces on top of Mick's throbbing demon shaft. The teen grins wolfishly as his rapidly warping mind takes in the sensation of Kristen's full tits pillowing against his rock hard chest as they spray hot streams of black milk, while Mick's bulging pecs and abs grind against his own muscular back.

Derek, meanwhile, has Maya bent over a nearby table, pounding into her from behind as she arches her back and grips the edges of the table for leverage. Eyes closed and mouth hanging open in pleasure, the athletic latina also looks to be surrendering herself to the Lilith Strain.

With an evil grin, you stride forward, walking around the table to present the lust crazed latina with your monstrous demon cock. Her face already twisted into rapt orgasmic pleasure, Maya doesn't even hestitate before leaning forward and working your engorged cock head with her soft lips and warm wet tongue.

You of course are going to completely hilt your cock down the infected slut's throat, and you're pretty sure that after taking a pounding from behind from Derek for several minutes Maya's fully infected enough for her gag reflex to be gone, but just to be sure you cum and fire a load of black ooze into Maya's busy mouth and all over her cute face, causing the girl to pause and cough for a few moments before being overcome by her lust once again and diving forward to regain her hold on your cock with her mouth. This time, you grab her by the sides of her head with your powerful claws and shove the full length of your demon shaft down her throat. The infected girl bucks and shudders for a few moments before the infection once again takes full control of her and she begins to deepthroat your cock like a seasoned pro. Derek, meanwhile, proceeds to thrust into Maya even faster and more ruthlessly, sensing his friend-turned-fuckmate's growing infection and lust.

After several more minutes your demon orgy reaches a crescendo as the two humans are fully overcome by the Lilith Strain and surrender their sweet souls to you and your wicked demonic packmates, joining your ranks in the process. Maya cries out in ecstasy as you and Derek consume her soul, her mind twisting into that of a ravenous demon whore as her body fills out with luscious curves worthy of her new lewd and warped mind. You grip her emerging horns for added leverage and buck into her face ruthlessly as her olive skin darkens to a deep crimson and bat wings and whip-like tail burst forth from her back, completing her transformation. The succubus eagerly absorbs a fresh wave of black cum from you and Derek before pulling out from your cocks and rising up to join you as you and Derek sandwich your new fit and voluptuous succubus plaything between your musclebound frames.

"Welcome to the winning side, slut!" you and Derek growl triumphantly to your newly created succubus as you explore her new wanton face with your elongated tongues.

The succubus extends her own oily tongue from between black lips to meet yours. "Glad to finally join, studs!" the depraved creature that used to be Maya purrs wickedly, her new heavy tits pillowing against the bulging pecs of you and Derek as hot streams of black milk leak from her rock-hard nipples. The succubus slut's soft hands eagerly fondle your powerful demon cocks, still coated in black ooze as rivets of your tainted cum continue to drip from the tips.

Jake, meanwhile, lets loose a powerful roar as the Lilith Strain claims him, his already confident and physically active personality warping into the same cocky, shameless, and aggressive incubus personality as his demonic violator. The succubus Kristen snarls gleefully as Jake's cock doubles in size within her hot demonic snatch, as his toned athletic frame reddens and swells with bulging muscles into the musclebound bodybuilder's physique of a full incubus. As his horns, wings, and tail complete his transformation, Jake shares a foul three-way kiss with Kristen and Mick, no longer their victim but now another savage comrade-in-sin.

The three young demons stand up from the armchair, pulling out from each other, and turning to face each other while grinding their sinful perfect figures against each other.

"Always knew you were a glorious slut!" Jake growls evilly at Kristen, groping at her spectacular boobs with one arm while the other wraps around the rock-hard waist of his incubus brother-in-arms.

Amanda and Megan hold each other fearfully and stare in horror at the wicked and debased creatures their friends have become, knowing that it will soon be their turn next.
