Sarah becomes a succubus

Damien smiled. He chanted in an ancient, hellish language that Donna couldn't quite understand. The air itself seemed to hum with dark energy. He leaned down and brought his lips to Sarah's in a searing kiss. She moaned, eager and compliant as a small ribbon of blue light unwound from between her lips. Her eyes widened and then glazed over with a look of ecstasy. She could feel her soul being ripped away from her body and she welcomed it, arching into him so that he could pull it out of her quicker.

He sucked in her soul and consumed her light, his body shuddering in dark pleasure as Sarah's soul filled him and made him stronger. His body tensed and he gripped Sarah's body tighter as he let out a guttural moan and pumped his dark essence inside her. Sarah cried out in orgasm, her last as a human.

Sarah's body writhed underneath his as her transformation began. Her pussy flushed crimson red as she felt his darkness within her changing her. The crimson spread across her body, covering up her chest, over her ample breasts and finally her face, a face that was once innocent and was now dark and feral.

As the crimson spread across her face, the blues of her eyes were swallowed by darkness until they were pools of solid black. No whites remained, only dark orbs that consumed all light.

She opened her mouth and moaned as she felt her teeth lengthen and sharpen into fangs. Her tongue lengthened and split at its end into a fork. She flicked her tongue out and tasted the air around her, the taste of the dark energy in the air palpable.

She felt her ears tingle at their tips as they elongated and stretched into crimson red daggers. She twitched her new ears as she picked up all kinds of new sounds that she could never hear as a human: the distant hum of the city outside, the sound of the air itself, the beating of Damien's heart. She could hear everything, feel everything.

Her hair, once a cascade of gold, darkened at the roots. The darkness spread across the strands of her hair and turned them pitch black. She shook her head and her new dark hair flowed down her back, the blackness stark against her new crimson skin. She reached up and ran her fingers through her new hair and a small smile crossed her lips.

She watched her fingers turn crimson and elongate. The nails thickened and sharpened into sharp claws. Her toes curled and lengthened, the nails thickened and sharpened in the same manner that matched her new claws. She flexed them both and moaned in approval.

The more he held himself inside her, the more she changed. She let out another moan. "Faster," she moaned, "Change me faster."

Immediately, she felt a sudden, sharp pain in her forehead. She gasped and reached up to her forehead where she felt her discomfort. At that moment, she felt two small, hard protrusions erupt out of her forehead. They hardened and curled into a pair of black demon horns that towered above her head.

She felt another sensation at the base of her spine. A new appendage pushed through her skin and grew out from above her ass cheeks. The appendage grew out of her body and lengthened into a thick, muscular and prehensile tail with a barbed tip at the end. She swished it behind her in a sinuous motion, the sensation both foreign and exciting.

As she swished her new tail, she felt another tingling sensation along her spine. Her eyes widened and she gasped as she felt something push through her back. She arched her back and moaned as a massive pair of leathery demon wings erupted from her back. They were a deep, obsidian black and stretched wide with a membrane that stretched between bones, each with a talon on the end of it. She moaned as she flapped her new wings, embracing their new power.

As she flapped her wings, the skin above her pussy burned. She looked down and saw a black pentagram burn itself into her skin just above her mons one line at a time. She let out a moan as the pentagram burned brighter and brighter. Then, as suddenly as it began the burning eased, leaving behind a dark brand against her crimson skin that pulsed with dark energy. Sarah felt the pentagram pulse in time with her heartbeat, a symbol of her new faith.

Donna stood frozen, her eyes wide with horror and her pussy wet with arousal as she took in Sarah's transformation. She caught a glimpse of the young woman's new crimson skin glistening underneath the lights, her new dark hair cascading down her back and her new demonic features and her breath hitched. The young, wholesome Catholic girl had been replaced by a creature of dark power and seduction.

Sarah ran her new demon claws along her transformed body. She let out a sultry moan that filled the room. "Yessssss," she breathed, her eyes half-lidded with pleasure.

Her claws traced the curves of her ample breasts and the horns on her head as she stared up at the ceiling. Her voice grew louder and became a defiant shout to the heavens. "I renounce you God! I am a succubus now! I don't need you anymore! I am Hell's whore now!"

Sarah's shout snapped Donna out of her trance and her breath came out in short, sharp gasps. She turned on her heel and bolted out of the studio, her heart pounding in her chest like a trapped animal. The image of Sarah's transformation filled her mind as she burst through the exit, the cool night air hitting her like a slap in the face. She leaned against the wall, her body shaking as she tried to process what she had just seen...and her arousal to having seen it.
