A magical duel and a sexual one.

The Sarah standing at the stairs barely had time to dodge as a bolt of fel magic shot towards her. She ducked below and considered her next course of action. She could not affort to spend to much mana here. Any spell she used would diminish her form and bring her soul closer to fading away. She had to be smart about this. A binding spell was her best bet. Low cost of mana and it wouldn't damage her body.

She stuck her hand out, taking the hit from the next fel bolt her other self had readied. It hurt. Her hand was gone, only a stump remaining. But this form had advantages as well, as Sarah saw her hand reforming from pure energy already. She used the time her other self needed to ready another spell to fire one of her own. She spoke the words and made the gesture as chains started appearing from thin air.

No. Not chains. Purple tentacles. There was something about purple tentacles. Something that bugged her. Like she almost remembered somthing, but it wouldn't fully reveal itself. The other Sarah screamed as the tentacles wrapped themselves around her arms and legs. There was a ripping sound as they slithered below her maroon robe and tore it apart, revealing her naked body beneath.

The other Sarah's skin was cracked, bright green light pouring through it. The same green as her eyes. Another sign the woman had fallen to fel corruption. Sarah moved closer, satisfied that her other version had been subdued. With her hands bound, there was no way for her to cast any spells. "Can you talk?" Sarah asked her bound counterpart.

The other Sarah replied. But it wasn't in the common tongue. Demonic sounds emerged from her lips. Sarah was familiar with the language of demons as she translated the words in her head. "I've got your body, bitch. Mistress gave it to me!" Sarah pondered her other self's words. Another was inhabiting her body. A fel spirit of some kind. No wonder her eyes glowed with fel energy.

"It does not belong to you! I will have it back. Leave now or face the consequences." The demon inhabiting her body laughed maniacally. "I'd like to see you try!" Sarah was getting pissed now as she closed the distance between her and herself. With a flick of the wrist, the tentacles pulled her counterparts legs apart making her pussy fully visible. Visible and vunerable.

The same cracked skin was present around her pussy and ass. A sign the corruption had spread there. Clearly the Shivarra had violated more than her spirit. Sarah took her erct cock in her hands as she lined it up with the familiar cunt. With one firm push, she entered and bottomed out. A warm feeling surrounded her girlcock, better than her hands ever felt as she started pulling back out.

She soon found a rhytm as she got used to feeling a tight wet cunt on her dick. At the same time, she used her fingers to channel mana onto her demonic self's skin. Purple runes started appearing on her stomach as she readied a ritual. Her plan was crystal clear to the warlock. Banish the demonic spirit form her body with the ritual at the exact same time she would flood it with her own essence.

The demon would cease to be and her sould would return to her body, making her whole once more. The demon inside her body noticed what Sarah was doing to her. "No! You can't do this!," it hissed in its demonic tongue. "I worked hard for this, earned it." Sarah grunted and moaned, speaking between her thrusts: "THIS... BODY... BELONGS... TO... ME!"

The demon whimpered at the sexual ****. "Please don't banish me! I will serve. I was wrong." Sarah noticed that the demon's pleas only made her hotter. She was getting off on dominating something bound. Something helpless. Something completely at her mercy. She felt herself getting close. The time for the magical words was now. She started chanting as she felt something inside her start to churn.

Sarah looked upon her prey as she finished the chant. The utter sense of domination and control sent her into an uncontrolled orgasm. Fluids sprayed from her cunt onto the floor below as her girlcock started spasming, filling her body with her seed. She saw the demons shining blue eyes dim, as she poured her soul essence inside. 'Wait? Blue? Weren't those eyes fel green earlier? And I have brown eyes,' Sarah thought briefly.

She wasn't able to linger on her thought as she felt herself dissapearing. With each spurt of cum, she became less corporeal. And as she felt her orgasm started to fade, she swears she felt something other than cum move down her penis and into her other self. It was bigger and round and gave her no small amount of pleasure. Finally she felt herself fully fade. She closed her eyes, hoping to be back in her own body when she next opened them.
