Retrieve the keys and run into a demoralizing sight.

You, Jake, and Megan rush over to the cabin that Warren and Jake were staying in. As the three of you cautiously open the cabin door and check inside to make sure there's no movement, Jake leads you and Megan to the room Warren was using. Rifling through the drawers by the light of Megan's gas lantern, after several minutes you find Warren's car keys tucked away in a nightstand. Quickly grabbing the keys, you and the two teens quickly leave the cabin. The three of you hurry back in the direction of the parking lot when you notice a pair of demons rutting in the middle of the camp, blocking your way. You and the two teens quickly duck behind the corner of a nearby cabin, Megan quickly extinguishing the lantern.

To your dismay, you see it's Warren and Kristen. Kristen is already fully transformed, bat-winged, crimson-skinned, completely naked, and on all fours in the dirt, back arched and full ass waving in the air. Warren is on his knees behind her ramming into her doggy style. The two newly turned adolescent fuck demons growl and snarl like animals as they rut in raw bestial sex, Kristen gleefully bares her fangs as she rocks and jiggles on all fours as Warren mounts her from behind and slams into her with powerful, aggressive thrusts.

As the three of you lie low to avoid being seen, you can see Jake clutching his fists in jealousy at the sight of Kristen being screwed by Warren in the dirt like an animal. Clearly the athletic young lad had feelings for the demure mousy girl, and is distraught at the sight of her being willingly violated by the incubus that used to be his skinny classmate.

Megan puts a hand on Jake's shoulder. "Come on Jake, that's not Kristen anymore. We have to get out of here, let's just sneak around them."

Jake chokes and shakes his head, before reluctantly nodding in agreement. The teen boy seems to be about to follow you and Megan in detouring around the cabins to get to the parking lot, but can't help but turn back and stare at the sight of the girl he cares for being savagely fucked raw by the adolescent incubus that used to be Warren. The two teen fuck demons' bestial growls and grunts grow more and more fast-paced as the two get closer and closer to climax. Sickened by the sight, Jake clenches and grinds his teeth while clutching the still fresh and painful claw marks running across his muscular chest from where Warren had slashed him earlier.

Megan once more tries to snap Jake out of his malaise, gently taking hold of his arm. "Come on, Jake, it's not her anymore."

Ignoring her, Jake shakes off Megan's gentle grip. Something primal kicks in within the young man's brain at the sight of his girl being fucked by another boy. Heedless of the danger, Jake bellows and stands before charging at the two rutting demons with an enraged battle cry.

Distraught, Megan is about to chase after him, but you manage to grab her and pull her into cover.

The two rutting teen demons spot Jake barreling down upon them and have only a few seconds to react with surprise before Jake lands a powerful kick to Warren's face, sending the teen incubus sprawling across the ground. The succubus Kristen hisses in displeasure at the interruption, but quickly grins and growls eagerly at the sight of the raw primal rage and masculinity being displayed by the enraged Jake.

"Get the fuck off her, you little prick!" Jake roars at Warren. Irrationally, the teen boy's emotions have overriden his good sense, and he no longer seems to be able to grasp that Kristen is no longer the demure girl he once knew, but rather Warren's willing and wicked demonic fuckmate.

The adolescent incubus rises to his feet with a snarl, turning to face his athletic human challenger. Striding angrily towards each other, Jake and Warren meet once again with fists flying, their bare, muscular forms locked in brutal combat. The two trade punches and grapple as you and Megan can do nothing but watch, and the whorish teen demon slut that Kristen has become eagerly observes the fight, the sight of the two fit, toned, and unclothed muscular lads fighting over her inflaming her perverted lust.

Surprisingly, this time Jake manages to get the upper hand against the teen incubus, wearing him down with multiple punches while managing to block or shrug off Warren's own blows. Finally, Jake grabs Warren around the waist and manages to wrestle him to the ground. Soon, Warren is face down in the dirt, Jake's well-built figure on top of him. The two hard-bodied lads are both growling and grunting with exertion and anger.

To your shock, something within Jake seems to have snapped, and the strapping teen boy suddenly rips off his boxers, revealing a fully engorged, erect cock. With a snarl, Jake mounts the prone incubus boy Warren, ramming his cock into the incubus' firm ass. The incubus initially snarls and struggles in protest, but quickly gives in and begins to yelp and buck in pleasure against Jake's enraged thrusts as the demon boy's innate bisexual urges take over and he gives in to the pleasure of his violation.

"Jesus Christ, Jake, what the fuck are you doing?!" Megan can't help but call out in despair.

"I'm dominating this little prick! Kristen is mine! I am dominant!" Jake howls, a wild look of mindless feral savagery in his eyes. The bloody claw marks on his muscular chest from where Warren slashed him earlier almost seem to be turning black, and the young lad's bronzed, muscular body seems even more rock-hard than you remember before.

"Fuck, I think Jake's gone! Come on, Megan, we can to get out of here!" you call out as you pull a struggling Megan away from the sight of her last friend falling prey to the infection.

As you and Megan dodge behind the cabins and circle around to get to the parking lot, you can only watch as Jake continues to mount the defeated incubus Warren in a depraved display of bestial animal instinct. Driven wild by the display, the succubus Kristen approaches her new clear dominant male on all fours, snarling with pleasure as she turns and offers herself for Jake to claim her. With a wordless growl, Jake pulls out of Warren and strides confidently over to his new succubus plaything, grabbing her lush hips for leverage as he hilts his incredibly engorged cock into her aching demon pussy and begins to ram her doggystyle, just like Warren was doing earlier. "You're mine now, bitch!" Jake growls as he ruthlessly pounds into the teen succubus, seemingly enjoying the fact that this isn't the Kristen he used to know, but rather a wanton demon slut horny for cock.

"Oh, yes! I knew you'd cum and join us, you fucking stud!" the ravenous demon slut that Kristen has become moans eagerly as Jake continues to fuck her, his mind already consumed by the virus and his body no doubt soon to follow.

Megan sobs at the sight of the debased creatures her friends have become as the two of you return to the parking lot.
