Zoe had to think long and hard about the offer. On one hand, she had the opportunity to become everything she dreamed of. She could be beautiful, sexy, and best of all, if the demon was to be believed, immortal. But that's the other side, she would be making a deal with a demon. A demon who had taken over her when she played the guitar but even then...the demon seemed to be telling the truth.
The deal was too good. "I accept your offer. Make me the most beautiful girl that I want to be."
The demon in the mirror began to smile deviously and snickered. Then suddenly the lights in her house went out for a moment and the demon disappeared from the mirror. Zoe began to look around but still didn't see anything. "What's going on?" Then a red hand moved over her shoulder.
"Ssshhhh. Do not panic my dear, you accepting my offer has allowed me to enter your world for a moment. Enough time to give you what you want." The demon quietly spoke into her ear. Zoe turned around. What she saw made he jaw drop. In front of her was one of the most terrifying yet beautiful things ever. The demon was beautiful with large exposed breasts, a perfect hourglass figure, and a face that no man or women could resist. Her horns were huge and had a tail that ended in a spade.
"Like what you see? Well, lets not waste anymore time." The demon leaned down and before Zoe could do anything the demon was holding her tight. "Just close your eyes and let it happen..." The demon leaned in and began to kiss Zoe intensely. She began to remove Zoe's clothing as Zoe wasn't going to be needing them soon. The demon reached one of her hands down to Zoe's exposed pussy and began to rub it furiously which caused her to moan in pleasure. "That's it. Let your inhibitions fall away as I give you your every desire. Give in to your temptations as you become beautiful, sexy, and immortal. Embrace your change. Embrace...your corruption. Embrace your transformation...into a succubus."
The last words caused Zoe's eyes to pop open. Of course there was a catch. The demon smiled before once again intensely kissing Zoe who was unable to fight back. The demon pushed her to the ground and began to grope her breast. Zoe's breathing quickened as she was nearing an orgasm, but then suddenly the demon was gone. It took her a moment to realize it, but this did little to comfort her though. "What have I done?" Zoe was beginning to panic.
"You are getting what you desire, what else?" The demon spoke to Zoe but she was nowhere to be seen. "Where are you..." Zoe said nervously. The demon then laughed lightly again. "I'm within you now and soon, we will be one." Zoe suddenly felt a strange tingling throughout her entire body. It began centering on her stomach where it began to gurgle and morph. It began to become toned and sexy with a v-shape and although Zoe couldn't see it, she could feel it becoming stronger. Zoe looked in awe as the change moved to her arms.
Her arms became slimmer and daintier but much like her stomach were being filled with a strength she had never known before but yet weren't becoming muscular. The changes then moved to her legs and thighs. Her thighs were filling up with fat at an increasing rate and she could see her legs becoming longer. However, Zoe was experiencing pleasure from this change so great it was almost impossible to suppress her moans. "Oh come now, my dear Zoe. Let us hear how much you're enjoying this change. Embrace it. There's no way to stop the inevitable."
Zoe tried to fight back harder. She wanted to be beautiful, but this wasn't what she had in mind. As she tried to resist, her hips began to wider into large child bearing proportions. Soon she had a perfect hour glass figure. The pleasure was becoming too much for Zoe who moaned out loudly and quickly moved a hand down into her nether regions. She began to rub her pussy furiously. "THAT'S IT! You're coming along nicely my dear. Just a bit more and then...we can really start your change." the demon in Zoe's head said in an almost calming manor.
Zoe's ass began to lift herself up as much like her thighs, they began to fill with fat making it plump but oddly firm as well. Her waist caved in slightly along with he back arching to really show off her rear. The change then reached her breasts and they quickly began to balloon out. Zoe used her other hand to grope herself as they quickly rushed passed D cups. "Yes...give in. Moan for me Zoe, this is your fate now. Let your bosom grow. Let it become the envy of all women and the desire of all men who gaze at it." Her breasts then reached E cups and finally slowed down until they reached EE. Zoe could feel her orgasm quickly approaching and was beginning to embrace this pleasure that was beyond anything she had ever felt in her life.
Zoe felt the pleasure reach her face as it became softer in touch but sharper in features. Her lips began to inflate until they were perfect for kissing. She felt her hair reach down her back, not noticing it was becoming a dark shade of black. But how could she notice with this ever increasing pleasure. She began to rub herself harder and harder until eventually...
"AAAAAAAAAAHHHHHHHHHHHHHHHH!!!!" Her orgasm was the most intense feeling she had ever had. "Good my dear...now its time for the main event."
The demon reappeared in front of the still recovering Zoe. "You and I will become the greatest succubus ever created. We will become the queen of all Demons. But first...we need to corrupt you. Corrupt you to your very soul as you become the perfect incarnation of lust and desire..." The demon reached her hand down and began to draw a heart shape with her finger tip when Zoe, even in the midst of the orgasmic throes her transformation had inflicted upon her, grabbed the demon's hand with her own hand. The demon had not expected Zoe to do that. "What are you doing?"
"...No..." Through short, sharp breaths as she did her utmost to stay in control even as her body was changing and her sensitivity climbing once more, Zoe lifted her still-human eyes to face the demon. "I said...the girl that...ahh...I want to be!"
"But it will!" The demon's hand within Zoe's grasp began to resume drawing a heart shape. "The Succubus Seal will make your wants match mine, your desires the same as mine!"
"What I...aaahh!..." Zoe tried to stifle another moan as she simultaneously resisted the building orgasm within her and the drawing of the Seal by the demon with her own hand as much as she could. "What I want...is not what you want!" With the last burst of strength she could spare from fighting off her physical desires, Zoe managed to twist the demon's hand as it finished drawing. The drawing, however, lit up and a surge of energy went through Zoe causing her to convulse slightly. The demon lingered for a moment, but once it was satisfied that Zoe's last-ditch interference with the drawing of the Seal didn't seem to affect it it disappeared again.
Zoe felt something arise in her mind, a feeling of the power and corruption that the Seal was to bring. The area around the seal began to turn red and it quickly spread down her legs. Images of men and women having sex began to barrage her mind, threatening to overtake her own thoughts -- Zoe shut her eyes and began to resist the onslaught: "Not my thoughts, not what I want, not my thoughts..." The pleasure and burning sensation was once again building in her pussy. The red coloring had reached the end of her legs by this point. Her toe nails began to extend and became claw like as they extended out.
Zoe got on her hands and knees trying to keep herself from masturbating again when she felt something poking out. A tail was beginning to form, one black as night but sensitive to touch as it extended to over a foot long and ended in a spaded tip. At the same time, Zoe could feel her insides changing, namely her reproductive organs. Her vagina became incredibly sensitive and felt like she could taste it. The sensory overload was too much and she rushed a hand back, her fingers delving in as it began to get larger and yet tighter all the same. The images in her mind became more intense as the demon once again spoke. "Give in...give in...give in to the pleasure. Let us become powerful. Let the corruption consume you."
Zoe whispered out "No..." as she poured all her mental strength into resisting but even as she said this the desires of a succubus began to creep up. A demon on the hunt for pleasure beyond any human's wildest imaginations. A being meant to satisfy the desires of all whom she crossed, like-
"GREG!" Zoe's eyes shot open, having just begun to darken until the moment she remembered the lead vocalist of the band she had tried out for...whom she had first transformed for...whom she had first pleasured...whom she had first killed. The darkening of her eyes quickly receded back, even as her skin continued to become more crimson as the changes moved up to her neck. "NO! NOT LIKE THAT!"
"Why do you resist?" The demon's voice seemed to permeate through her soul, as Zoe felt two things start to poke and grow out of her back. Looking at her shadow, Zoe saw two bat like wings extending out from her back, just as black as her tail and beginning to flap behind her. At the same time her fingernails also began to extend, becoming sharp but oddly did not hurt her. Instead it only made everything more pleasurable, increasing her pace as she masturbated faster and faster while also groping her breasts. Zoe arched her back up as the crimson began to move up her face. "You see? How could you be enjoying this so much if there wasn't a place within the depths of your very soul that didn't want this?"
It wasn't long before Zoe's face was completely covered in crimson and two horns began to poke out of her head. They were painful at first but then began to add to the pleasure of the rest of the change. Once they finished they were long and pointy, sharp enough to kills a person. That thought sent shivers through Zoe. She darted her eyes open, gritting her sharpening teeth as the demon whispered again: "Give in...this is the new you...let the corruption consume your mind as we become one."
Zoe's breathing began to hasten as her hands continued to stroke her sensitive...everything now, her mind becoming exhausted trying to resist the corrupting thoughts of sex and killing. "I....haa...I....am..."
