The night of the party

Over the next few days, Stacy's body had taken some subtle changes. Her hips had flared slightly as well as the waist narrowing a small amount. Her nipples and clitoris had become more sensitive, and her cheek bones had risen slightly. Along with those changes, her tongue had increased in length and her canine teeth had grown a couple of millimetres. She had trouble with the dark lustful thoughts running through her mind but managed to keep them at bay. "Fuck I need to get a boyfriend." She thought to herself. "Should be a couple of cute guys I can hook up with at Taylor's house. Been too long." No one noticed anything different about her though. The changes were so subtle that you would have needed a computer face recognition programme to see them. It was inside her body that the biggest changes were taking place. Her blood and veins had become darker. The blood almost black, readying her body to become the ultimate being of lust. Stacy was also compelled to learn all she could about the legend of the Succubus. Everything that she was going through. Everything she found out about the Succubi didn't put her off of wearing the suit again for the party. If anything she couldn't wait to wear it again. Two days before the party, the dark forces at work had now started to talk to her. They didn't worry or alarm her one bit. They felt natural. She felt as though they were worshipping her, calling to her to rise once again. Telling her that the suit would allow her to become her true self. And still, she couldn't wait to wear it, but tried to wait out until the day of the party.

On the night before the Taylor's party. Stacy couldn't resist the urge to touch herself. Her parents, out for the night, left her alone to be as adventurous as she wanted. "Fuck it. I'm gonna put the fucking suit on." Pulling it out from her wardrobe, she changed within record time. Once fully changed, she admired herself in the mirror again. What she didn't notice though was that she found it easier to see clearly than previously. The suit felt like it was part of her. Without further delay, Stacy went to her secret drawer under her bed and pulled out her favourite toy. An 9 inch long dildo with a suction cup at the base and proceeded to insert it into her very wet pussy. "OH FUCK ME, YEEES." Stacy kept thrusting the rubber toy deep into her snatch at an inhuman pace. "OH FUCK. COME STUD. RAM MY PUSSY FULL." Thinking it was just her getting into character she screamed. " FUCK ME HARDER YOU CUNT. RELEASE YOUR CUM INTO ME. DO IT AND GIVE ME YOUR FUCKING SOUL." The furious self pounding and her words tipped her over the edge and she came harder than she ever had. Laying back on her bed, she panted trying to regain her breath. "Oh my god that was so fucking hot." The voices had stopped calling to her for the time being. But her orgasm had changed her further. The canine teeth had lengthened once more and were now clearly longer than before. Her tongue longer and thinner. All these changes seemed natural to her. What she didn't notice though was the tail and wings of her suit had now gained free movement. They had become almost alive while she wore the suit.

When Stacy noticed the time. It was nearly 23:00 hours. " Shit. I better get out of this before mum and dad get home." Once again changing in record time back to her normal clothing. But the dark thoughts remained. Stacy still felt horny but was satisfied enough to hold anymore pleasure at bay. But she had also tired and decided it was time to sleep. Through out the night, her dreams consisted of her dominating any man she found and condemning his soul to hell. Smiling in her sleep as she did so. Even her own father had succumb to her charms and fucked his daughter only to become her ****, but one that would hold a position of authority over the other slaves, maybe more.

Come the morning, Stacy felt better than ever. Moving and walking gracefully and seductively throughout the day. Impatience for the party had been growing throughout the day, The voices returning. Telling her to lead them once again. Stacy felt no alarm at these voices. Simply replying to them with her own thoughts. "Patience my friends, all in good time." But she still had no idea who they were. But the party would soon be upon them.

Stacy remained as patient as she could until it was time to go. Once again, getting ready and replacing the suit on her body. This time, it felt even better than before. Like she belonged in it. "I could wear this all the time. It feels so right to be in this thing." She mused to herself. Once she arrived at the party, Taylor greeted Stacy. The party was already in full swing. Music blasting out from the large stereo. A large number of people had come to Taylor's Halloween bash, including a number of guys that had been invited along with Taylor's older brother Martin. And it was him that Stacy had set her sights upon. But patience was a virtue in her plans.

"That's one hell of a costume you got there Stacy." Hearing a voice behind as she grabbed a drink from the punch bowl.

"Gina. How you been?

"Good, Did you have a rotten hangover too from the other night? God knows how much **** those drinks had in them."

"Fuck god." Stacy spat. "I'm a demon remember."

"Wow. Stace. Getting into character a bit much aren't we?"

"Character. You have no idea Gina. I feel awesome in this suit. I've been studying about the Succubi and intend on getting everything just right."

"Got ya." Gina smiled and winked at Stacy. Thinking Stacy was just role playing.

As the night wore on. Everyone mingling around and changing who they was spending time with, and Stacy was now getting more and more involved in her so called role play. As she looked around the room, She noticed that a number of guests had settled and were engaging in some heavy kissing. Stacy's powers were growing and she was spreading lustful thoughts into the others around her. Only she never saw Martin around. Deciding it was time to go and prepare her **** on him, she went to bathroom first, just to double check her costume was perfect. Instead though she went straight into Taylor's parents room to check herself in a full length mirror. Running her left hand up her leg, and her right on her breast, she felt the claws on her hand scratch at the surface. "Hmmm. That feels divine." She applied more pressure and scratched her suit. Only it was no longer a suit. Stacy and the costume had merged. It was now her skin, and from the scratch pooled a small amount of now tainted black blood. "I need to feed. Where is Martin I wonder." Bringing her now living tail to her mouth to suck on the end of it, and raising her wings. Her eyes now an endless pit of black with red glowing iris's in the middle. Martin appeared at the door to the bedroom. Stacy had summoned him from where ever it was he was hiding.

"Stacy. Did you just call me? This is my parents room. And I don't think they'll be happy if they knew someone came in here." He stated as he walked forward. But Stacy didn't care. She was no longer Stacy.

"They won't know." She casually flicked her hand out and with the first use of her now growing demonic powers, closed the door. "Fuck me." She approached Martin with a sway in her hips as she walked. Martin seemed hypnotised as he was unable to retreat.

"Stacy. This is not a good idea."

"My name is Lilith, Martin, and you will be my first." When she reached him, She pressed her lips to his and wasted no time in placing her new forked tongue into his mouth. Within seconds, Martin was completely unclothed and laying back on the bed as Stacy/Lilith had pushed him with ease. She pounced on him, and not waiting or engaging in any foreplay, impaled herself on him. "Oh yes Martin. That feels wonderful. You will be mine soon." Bringing her tail around to wrap around his neck. "There will no escape until I have finished with you." She lifted his upper body up with the tail that was around his neck and then wrapped her wings round his body too. He was trapped in a vice like grip by Stacy's/Lilith's inhuman strength. She proceeded to rock back and forth on his groin and then bounce on his cock. "Fuck yes Martin. I had no idea you was packing such a good cock for a human."

"What has got into you Stacy. God your pussy feels good but something doesn't feel right."

"Don't mention that cunts name. He can't save you now. I am Lilith now. And with your soul I will start to remould this earth to my desires." Martin was now losing his will. His mind now engaged in dark thoughts too. Lilith had entered his mind and corrupted his thoughts.

"Go for it Lilith. Let me please you." He was now in her control. And she laughed. A laugh that shook the room. Lilith was now nearly at full power. Stacy no longer existed. What was once a promising student was now a full blown demon of lust.

"I knew you would see sense Martin, Now let me give you my body and you will soon know what it is to be free from obligation, free from this mundane existence." She got off him and got on her hands and knees. "Ram your cock into my pussy. Do it, and I will show you a new and exciting future." Martin could not resist her. She was perfection. All Martin wanted now was to be inside her warm embracing body. He placed the tip of his cock at the entrance to her crimson skinned pussy lips and pushed in hard. "Yes Martin. Fuck me hard and you will be rewarded handsomely." Martin began thrusting into her with everything he had.

"You feel so good Lilith. I've never felt a pussy so tight or wet."

Meanwhile downstairs, due to the influence of Lilith's presence, A full blown orgy had broken out. The lust in the atmosphere had **** everyone to give in to their desires. Even ones they didn't want to admit too. All around the house people were engaged in various couplings, heterosexual and homosexual. It didn't matter. As long as they had a partner to engage in illicit activities with. All this fed Lilith's powers, making her stronger and more demonic. Completely erasing Stacy from existence and condemning her soul to the pits of hell.

Back in the bedroom. Martin was now hammering into Lilith. Determined to please her and win her favour. "YES MARTIN. KEEP ON FUCKING ME. CUM IN ME WHEN YOU READY" Her tongue hanging from her mouth, baring her full length canine teeth. Her eyes now glowing from the lust that was being played out throughout the house.

Martin was close to the edge and ready to cum. "I'm close Stacy. I'm close but I can't cum, something is stopping me."

"STOP CALLING ME BY THAT STUPID GIRLS NAME. She no longer exists, I am Lilith now, She allowed me back into this world and she will spend an eternity for her stupidity in hell."

"Please. Lilith, I want to cum." Martin was pleading. His balls were hurting him and he was **** to release inside the returning Succubi queen.

"If you want to cum then you must release you soul to me. Do it, and you will never want for anything again. You will never age. You will be one of my honoured slaves."

"YES. ANYTHING. JUST LET ME CUM."

"Very well my ****. You may cum into me now." Martin unloaded all his sperm into her, and with it his soul too." His face then became blank as his mind adjusted to the lack of a soul. Lilith threw him off of her and turned to face him. "Good ****. You will do well in my new reign here in this realm. Let us see how the rest of the party is coming along."

"Yes my Queen." Was all he said, and followed her. When they reached the bottom of the stairs, all eyes fell upon the floor. Everyone had knelt before her. On her first night back on Earth, Lilith had corrupted an entire party of teenagers and filled their thoughts with nothing but lust and it sealed their fates to total obedience to her without losing their souls, until she slept with them. Lilith was now truly back to bring about a new future. One she once failed to hundreds of years ago. But in this day and age of science and lack of religious followers, it would be much harder for her enemies to send her back to hell and defeat her. Finally, she could rule over the Earth and eventually, maybe implement her plans to overthrow Satan himself.
