Caitlin Stops It

"YES!" Marissa moaned enthusiastically, she had never felt more aroused. Her body burned with pleasure, desires, jealousy. The idea of Steve fucking his own sister riled her up in a way she couldn't have imagined prior to watching him fuck her own sister. She stared to the ceiling feeling the soul shattering orgasm beginning to take hold.

"NO! Anything but..." Caitlin cried aloud arms stretched out towards the demon fucking her sister. What had she done? First fucking Steve so irrationally, then letting her sister join? Oh how amazing it was! She felt her hold slipping.

"I'm so sor..ree.. Ma..ris...saa.." Caitlin sobbed and gasped as she shed her final tears. "OH!" She screamed in pleasure, dropping to her knees, jutting her tits forward as she arched her back in a soul shattering orgasm. She had made a verbal plea, and the Idol was taking it. "I'm... SO.. SO... SOrr... eee..." Caitlin moaned and groaned in exquisite unbelievable pleasure. She fondled her breasts, mashing them together in utter delight of her new form taking final shape and hold. As she pulled her breasts together and fondled them with her left hand her right descended to her snatch rubbing her clit before descending into her pussy, providing her first taste of the soulless pleasures she now embodied.

Marissa whimpered, and moaned in desperation. She felt the orgasm slipping away, all the pleasure was dulling. Like her whole body seemed sedated from the supernatural pleasure that had been overwhelming her and burning the very fiber of her being. Gazing towards Caitlin she watched her sister become a succubus. Her sister had stopped her. Her sister had taken the pleasure, her body cried for it as it descended into withdrawl. Steve lifted her from his cock and put her down, stepping over to her sister.

Marissa went to cup her breasts, they felt numb, they felt small... Looking down she took in her body returning to its previously uncorrupted beauty. No.

"YOU BITCH!" The Idol had agreed to let go of Marissa for Caitlin's soul. But it didn't do so without leaving a suggestion. Her sister had stolen it, ALL of IT. The beauty, the pleasure, and then SACRIFICING HERSELF! "YOU HAD TO GO AND DO THAT! GIVE IT UP AND DEPRIVE ME! Maybe I don't want to be stuck without you. MAYBE I REALLY WANTED IT ALL!"

Caitlin smiled and giggled at her sister as her clawed hands explored her flawless hot pink hour glass body, her long serpent tongue lapped at a nipple, tasting the delicious nurturing corruption she now could lactate as her tail waved about like a cat's. Putting on a playfully straight face she paused for a moment taking a break from her new existence to be empathetic. "I said I was so, oh so sorry. No one should ever miss out on such a soul shattering orgasm."

Marissa slapped her across the face, she didn't know what else to do. As angry as she was, she could still feel herself aroused by the beauty of her sister, and the neighbour turned demon with her. She still felt wet, she was still affected by the smell of sex and pheromones, but everything felt dull compared to earlier.

Caitlin meanwhile rubbed her cheek, feeling even more aroused by the slap she had received.

"WHAT'S GOING ON..." Like a thousand times before, throughout their childhoods. Before college, even highschool. Their mother had been woken by yet another argument.

Sylvia had been asleep. Her dream was troubling her, she couldn't make out why. It was far from her mind as she awoke in a warm sweat and heard the muffled screaming. Glancing at the clock she shook her head.

What could her daughters be arguing about at 1am! Getting up she marched towards the door, out into the hall, past the bathroom, Marissa's room and flung the door open to Caitlin's room wide open.

Like a thousand times before she began the sentence "WHAT'S GOING ON..." The sex and pheromones in the room hit her like a wave of water, added to the momentary stun was not her two daughters, but Marissa completely naked, alongside two devils for lack of a better term.

Sylvia never recovered from the shock as the room suddenly spun, and she felt her body hitting the floor with the **** of slipping on ice. Her shoulders were quickly pinned down and Steve kneeled atop her chest stroking his cock into squirting a load onto Sylvia's face and open mouth as she tried to shout.

Steve and Caitlin exchanged knowing glances, they both could smell Sylvia's arousal. The pheromones had made their way to her room and begun to penetrate her dream. Sylvia sloshed Steve's black cum around in her mouth, looking to find her voice only to find his cock on her lips eager to shush her. The mere touch of it delivering a pleasant warm electrical tingle.

As Marissa gasped at the tail tripping her mother and Steve's quick action to mute the interruption to her argument by her mother. Caitlin leapt into action. Tackling Marissa back on the bed she held her sister there for a moment.

"There's a way we can fix this." Caitlin stated looking her sister up and down. "I'm truly sorry for stealing it all. I should have just waited for you to come to me, and bless me with this." Caitlin brushed her breasts across her sister delicately, all while sounding genuine and sincere. As Marissa glared angrily, with jealousy amplified in part as a parting gift by the Idol Caitlin continued. "You can will the protection away."

"And how would I go about that?" Marissa matter of factly replied with all the blunt attitude she could muster while squiriming under her sister.

"Continue fucking with us. Involve yourself in the fall of 3 more souls, and you will be even more than me. I was a soul that fell to it. You'd be a soul that willed itself to the Idol." The words aroused Marissa, dark thoughts whispered about how she could be more than her sister, better, more beautiful.

But how could she do such a thing? Marissa watched as Caitlin got off of her and crawled over to Steve. As she came around him, she could see he had gotten his cock head between her mother's lips. Sylvia's eyes were wide with fear and concern.

She tried to keep her mouth clenched shut as the cock descended into it, but couldn't understand her body's lack of will to resist. She wanted to bite the cock but found her tongue slowly lapping around it, reminding her of the delectable taste of the cum it had squirted across her face.

Marissa got up, modestly covering her breasts as modesty returned to her she walked around and watched as Caitlin lapped the last of Steve's cum off their mother's face with her dexterous tongue. "Come now mother, we just want to make you young and beautiful again. We know you want to, we can smell it on you." Caitlin lewdly uttered to their mother before looking to Marissa invitingly.

Marissa was torn, some morality and inhibition had returned to her, while she could feel her body tremble in withdrawl from the pleasures if had experienced. Could she bring herself to help 6 souls fall to her sister and their neighbour?
