Alex & Olivia

Carla's eyes were bleary as she briefly parted them and was able to make out the crimson shapes of Alex & Olivia above her. A faint "No" slid from her lips before she slipped back into the darkness. Laying on the grass she suddenly felt a pair of taloned hands wrap around her ankles before roughly prising her legs apart.

A timbre growl caused her eyes to snap open as she looked upon her former partner. The Incubus bore his fangs as he held her legs in his vice-like grip. Carla began to scream incessantly as Alex thrust his herculean cock into her gaping pussy. Her screams continued as the Incubus ruthlessly pounded into her, a few feet away she could hear Olivia’s melodic laughter as she sauntered over toward them.

Olivia grinned as she eased her voluptuous body down atop the screaming girl's features, the last thing Carla saw was the Succubi’s blackened pussy before her face was enveloped by it. A wave of panic ran through her mind as Alex increased the ferocity of his thrusts. Not wishing to become like them she held her breath and hoped that she would not succumb to the succubi’s musky scent.

Alex’s eyes darted down to see Olivia sat atop Carla’s face as he dropped her a knowing wink. The Succubi’s ear’s flickered as she heard Carla take a deep breath, wanting to make the slut squirm Olivia eased her cock-tipped tail from under her before slowly easing it between her preys moist cunt lips. Carla barely managed to stifle a moan on feeling the alien intruder slip between the folds of her sensitive flesh.

The Incubi bore his teeth as he caught sight of the Succubi’s actions and quickly eased his tail in alongside her’s. Carla knew she was able to hold out for so long against one intruder but two was pushing it. As the long guttural moan slid from her lips, Olivia sprayed a stream of infectious cum between her lips whilst Alex erupted inside her.

Carla’s mind broke as she was assaulted from all sides, with the Lilith Strain running rampant throughout her transitioning body the terrified girl no longer cared. New animalistic desires and sinful thoughts ran through her swiftly corrupting mind as she roughly grabbed Olivia’s thighs and pulled her questing tongue closer to the Succubi’s oozing cuntlips.

Olivia threw back her luscious jet-black locks and grunted in sadistic pleasure as she felt Carla’s lengthening tongue tickle her erect clit. Alex watched in morbid fascination as his former lover’s plump pussy lips were rapidly gaining a pitch colour as her skin shifted into a hellish crimson hue. An orgasmic yowl slid from Olivia’s lips as she felt Carla’s fangs slice into her slick pussy. Cum coated Carla’s shifting features as she revelled in the taste of her lover’s corruptive seed.

Alex’s slit eyes darted down as he watched Carla’s gleaming blonde locks swiftly shift into a luscious pitch mane. Carla could feel herself slowly push away from the ground below as her formerly flat rear ballooned outwards into a pert bubble butt. Cum oozed from between her folds as she gripped onto the invading phallus and milked them for more of their wicked seed as her demonic corruptors groaned in blissful agony.

Olivia ran a taloned hand across Carla’s inflating DD rack as she twisted a blackened nipple and heard a pleasurable yowl from the smothered slut below. Cum coated the floor below as Olivia eased her voluptuous form away from Carla’s onyx lips. The Succubus blinked as she revealed her newly slit serpentine eyes that gazed upward toward her sister in sin.

Carla purred in delight as she gripped the floor with her taloned hands and pushed herself away from the sopping grass with an almighty shove. Her pussy clung to Alex’s mighty cock as she flung herself into his arms moments before two leathery bat-like wings erupted from her back. As the newly reunited lovers' lips slid over one another’s, two ram-like horns pushed themselves out from Carla’s forehead as her transformation came to a glorious finale.

As the three demons pried themselves free from one another’s grasp a smash from the garage turned their predatory gazes toward it. Carla bore her fangs in excitement as Olivia snarled wantonly before the three of them stalked menacingly toward the building...
