Not invited!

Kyle was in a bad mood.  His stupid step-sister was holding a birthday party tonight and his house was going to be full of her douchebag friends.  Worse - Mom and Dad were going out for the entire evening and staying over with their friends, leaving him alone whilst Lauren's friends ran riot over their house and inevitably stayed up till 5AM in the morning partying like the sluts they were.

The worst bit was that he had heard Lauren talking on the phone to her friends that tonight she was planning to fuck her hot boyfriend Jackson.  Listening to his step-sister moaning through the thin wall of the adjacent bedroom was not going to be any fun.

A sudden knock at the door startled Kyle and he went to answer.  He pulled it open to reveal an attractive blonde girl in a pink top with a superior, bitchy expression.  She regarded Kyle for a moment and then her face broke into a bitchy, fake, smile that screamed of patronising Alpha-girl.

"Ohhhh, you must be Lauren's little brother, perrrrrfect," purred the girl as she looked him up and down.  "Yeah, you'll do nicely."

"Excuse me?  Can I help you?" asked Kyle in annoyance at this bitchy girl and her strange attitude.

"Oh yeah - my names Kayla... and your bitch sister and I fell out a week ago.  The slut has withdrawn my invitation to the hottest party of the year and left me out in the cold.  But... no hard feelings.  I still wanted to give her a present and make sure she has a special day."

Kayla produced a plain looking jewellery box and thrust it into Kyle's hands.  "Take this and give it to her will you please little boy? Oh and whatever you do, don't look inside. It's not for pathetic little boys like you. You wouldn't be interested in the contents, at all."

Turning on her heels, Kayla stalked off with a big smile of her evil face.  She was a vindictive bitch and even though she and Lauren had fallen out because she'd tried to seduce Jackson, she wanted revenge.  How dare the little slut not invite her to the biggest party of the year?  Well - if her plan worked, she had just made sure that Lauren would have the worst birthday party ever and that from now on she wouldn't have it so easy at home.  It amused her just to think about it.  With a giggle she strutted off home, content that her plan was now in motion... and so pleased that her Mother had taught her black magic.  Those lessons were about to pay off big time...

*******

Meanwhile back at the house Kyle was curious as to what was in the box that the bitchy girl Kayla had given him.  Girls were weird - why would you buy someone a present that you didn't like anymore and hadn't invited you to their party?  Going up to his room, he decided he would have a quick look.  Kayla hadn't wrapped the present and it was just in a flip-open box, so it would probably be easy enough.

Popping the lid, Kyle looked disappointingly inside - Kayla had been telling the truth - he wasn't interested in the contents.  All the box contained was a big pair of slutty, big hoop earrings like some bratty party girl would wear.  He went to close the box, but found he couldn't.   

Put them on... put them on... put them on...

Kyle groaned as Kayla's voice seemed to suddenly whisper in his head.  He could hear the bitchy girl's voice inside his mind and a terrible compulsion to obey her throbbed through his entire being. His hands shaking he reached down and took a hooped earring out of the box.  The hook in the earring was sharp and trembling, his fingers reached up to his lobe.  Kyle didn't have pierced ears and the only way to put the earring on would be to literally force it into his own flesh.  Fear of the inevitable pain overcame the voice and his hand stopped inches from his face.

PUT IT ON... PUT IT ON... PUT IT ON

Kayla's voice rose in power and Kyle desperately tried to fight - but he couldn't.  His hand jabbed down, and he winced - expecting pain.  But the hook simply seemed to flow into his flesh and pop out the other side and to his amazement he realised his right ear was now pierced as if it always had been.

"Wh... what the hell is happening?" he groaned, as his hands darted down and grabbed the other earring - raising it to his head.

Obey your desires. Put the other earring on.  You love how the earrings make you feel.

Kyle was pretty sure these weren't his desires but he couldn't stop himself sliding the other earring in regardless.  Now he had a pair of slutty hoops hanging from his pierced ears - this was crazy.

Hahah, don't you look pretty?  I'm inside your head now Kyle and I can see and feel everything you do. The earrings give me complete control, you're my puppet.  You may be wondering what is going on here, well, your sister is a fucking bitch, so we're going to have revenge on her, hissed Kayla's voice in his head. 

I'm going to turn you into her hateful younger sister... a total homewrecking bitch and irresistible to men.  You're going to ruin her dumb party and you're going to enjoy it.  I'm going to corrupt you into a bad little slut that enjoys ruining your sisters life and fucking her boyfriends.  Tonight you're going to ride Jackson... then Lauren will regret not inviting me to her party.  Don't try to resist, my cursed earrings completely control you now.

"No! This is insane," whimpered Kyle, "I don't want to be corrupted. Please don't do this."

Oh - I'm sorry, but what you want doesn't matter to me.  Besides, you'll thank me eventually.  Boys suck - and you'll much prefer being a hot girl. I'm afraid your transformation is going to be permanent and soon you won't even remember Kyle.  Any changes I make take root in reality.  Everyone will believe you've always been Kyler.

"Kyler?"

Yes, Kyler.  That's going to be your new name.  In fact - you'll find you think of yourself as Kyler from now on and you'll find that you can't even remember your old name anymore.

Kyler gasped as he realised that Kayla was right.  He couldn't remember ever being called anything but Kyler.  Cold fear gripped him and he tried to raise his hands to take off the evil earrings, but he couldn't. His fear was palpable, but in some ways he was horrified by another feeling inside him... excitement. There was a dark twisted part of Kyler that was suddenly enjoying the thought of being transformed and corrupted by Kayla.  He tried to suppress it but couldn't.

Your sister isn't in yet, so lets go to her room and get ready for the party. 

Kyler stood up and walked into the hall, then into his sisters room.  He looked around at her stuff and felt his legs moving by themselves to the vanity table. 

Take off your stupid boy clothes, you won't need to wear those ever again. Eugh, so boring and plain and worthless.  You only want to wear girls clothes from now on. After all you deserve clothes that make you feel sexy and alive... don't you Kyler?

"Ye... yes," moaned Kyler, unable to disobey the voice.  When Kayla suggested something, it became a fundamental part of his being.  In one sentence she had made him hate male clothing and only want to wear girls clothes.  He ripped off his black t shirt and tracksuit bottoms, kicking off his underpants until he stood completely naked.

Before you get dressed we need to make some modifications to your body.  Lets start with all this ugly body hair.  Grab that razor and that can of shaving cream.  Rub it all over your skin and get shaving.  I want every inch of you completely smooth and slutty.

Compelled by Kayla's power, Kyler sprayed the slippery white foam onto his legs, arms, and chest and began to shave.  Kyler didn't have that much body-hair, but what little he did was easily swept aside and to his horror he saw that wherever the razor passed his body seemed different!  The razor wasn't just removing hair... where it passed it left his skin smooth and sexy... like a girls.  Soon his chest, legs and arms were gleaming.

Doesn't that feel better? Boys love a smooth body.  But there's more to do and we need to make some very important changes. Spray that can all over your useless balls and willy.  Fucking cover it all up till you can't see it. I don't want to ever see it again, laughed Kayla.

Kyler groaned as he emptied the rest of the can over his crotch. The thick foam piled up and he felt his dick tingling strangely underneath the heaped mass of white foam.  Urged by Kayla, he reached down and wiped away the foam to reveal that his dick... was gone!  Instead a tight pink slit, winked up at him... a perfect bare pussy with a needy little hole and soft pink folds around it.

"Oh no my dick is gone," he groaned in horror... but also with a thrill of fascination.

That's right. What an improvement. You'll enjoy having a pussy soooooo much more, believe me.  Yours is super pretty as well. The boys are gonna love it.  I guess now you have a pussy, you should probably think of yourself as a girl. Hey Kyler?

Kyler nodded, she couldn't fight the suggestions. She was a girl now - well almost.

Grab that moisturiser and give your chest a rub.  You need some boobies and with a little bit of encouragement I think I can help you out.  

Kyler did as she was instructed and opening a tub of her sisters moisturiser heaped it into her hands and began to rub her flat chest.  As she did so it tingled and the nipples got hard - pushing out from her chest as two small, perky breasts formed.

That will do... I think you're more a skinny pretty girl than some busty bitch. We don't wanna go too big.  We'll give you a nice ass though.  Moisturise your bum... oh and rub some on your hips too... you need to be wider.

Kyler obeyed, and she groaned as her hips cracked out and her bum inflated into a girls perfect peachy ass.  She now had a woman's body and it felt really good. 

Time to complete your look.  Sit at the vanity and grab that makeup.  Don't worry, I'll guide your hands so you don't fuck it up.  I'll give you a crash course on slutty makeup... you'll love how it makes you look.  

Kyler sat, feeling more cushioned than ever on her bouncy little ass.  Her hands darted out and she grabbed eyeshadow - foundation, concealer and mascara.  Her hands went to work with the brushes and as she applied the makeup her face began to change. Her boyish features became feminine and pretty, with big sexy long lashed eyes, soft pouting lips and a mischevious looking face.  

Ohhhh you're so hot, Lauren is going to be so mad her little sister is hotter than her. I LOVE IT.  Now for your hair... grab that brush and run it through, each stroke will make your hair look sexier.

Kyler obeyed, the brush gliding through her hair and with each sweep it got longer, silkier and sexier. Soon it was back-length and fell around her ears and shoulders in a shimmering wave.

Yay - the physical changes are done.  You're one of us now Kyler, you're a beautiful girl.  But it's time to turn you into a dirty slut.  Time to put on some clothes and change your personality to that of the bitch I need you to be.

"No please," groaned Kyler, "I'm sorry that my sister didn't invite you to the party, but you can't do this to me. It's not fair, I didn't invite you to to corrupt me."

Hahaha, you should be thanking me.  I'm turning you from a useless boy into a hot mega-bitch, just like me.  In fact - I think you're gonna be my new best-friend once all this is over. We're gonna hang out and have so much fun.  Now go into your sisters wardrobe and lets find something to wear.  Black please.

Kyler walked to the closet and inside began to search.  Her fingers snagged on a pair of tight black leggings with cross slits on the side and she pulled out a tight black bralet to match.  These were the clothes a nasty party girl might wear.

Yes, see - you have excellent taste. I barely influenced you at all there.  Now it's time to transform into a slut.  Go to the mirror and watch yourself putting on the clothes.  Grab those black high heels too...  I want you to imagine you are transforming into a hot, manipulative, super feminine bitch with each item you put on.  As you slide into your new clothes, the old you will die and Kyler will be fully born.

Her pussy tingling, Kyler slid her long smooth legs into the black leggings and groaned as she pulled them up. Sliding the clingy black material up her legs she felt a surge of confidence and bitchiness flow into her. It felt so fucking good to dress like a naughty girl and snap the waist band of her new leggings around her perky bottom.

Whilst Kayla's voice egged her on, another voice... that of some boy was screaming and trying to stop her from putting on her bralet. She ignored the loser as she smirked and her hot pink lips twisted into a smile.  Gawd, she was so fucking hot... she was an evil bitch who got whatever she wanted and she loved it.  Moaning, Kyler fastened her bra and stretched her perfect young body... loving how it felt to be horny and popular.

Sliding her delicate feet inside her heels, she moaned as the boys voice vanished completely from her head and she felt a delicious tingle as she realised that she was a bad, evil, bitch.

Yes, you're hot... you're bitchy... you're popular.  Your sister is jealous of you and you love to tease Lauren that you're the hotter and more popular one.  Most importantly, you have a huge crush on her boyfriend and tonight you're going to fuck him.

"Yes... tonight I'm going to fuck him," giggled Kyler as her new personality and desires locked in and Kayla's perfect weapon for revenge was finally fully created.

Mmmmh, I think you're ready Kyler.  I'm going to shut up now and let you take full control.  I'm gonna ride around in your head and enjoy every minute of this.  Even though I wasn't invited to this party - I'm gonna gatecrash it through being inside your mind.  After tonight, you won't remember any of this. You'll wake up tomorrow believing you've always been Kyler and that I'm your best-friend.  You'll remember what you did at the party, but nothing about me corrupting you.  Thanks for making this so easy - I'm looking forward to seeing you go to to work. 

Kyler grinned... "I'm looking forward to getting some hard fucking cock."

Her pussy already tingling in anticipation, Kyler made her way downstairs just in time to see her sister entering the house.

"Damn it Kyler, you were supposed to help me set everything up," hissed Lauren in annoyance. "You're such a lazy little slut, I can't believe you've done nothing."  As far as Lauren was concerned, her hot little sister had always been this way.  She remembered nothing now about Kyle.  "What the fuck are you wearing, you look like a whore! Eugh, it doesn't matter I guess... just help me now will you? "

"Awwwwww, sorry babe," giggled Kyler, "I guess I got distracted.  Look - I'll try and help out now. Hey when is Jackson getting here?" she asked innocently, "is he coming to help?"

"He'll be here soon, now help me inflate some balloons will you?"

The sisters set up the party and soon they were good to go.  Kyler was bored... she wanted to fuck and she couldn't wait to sink her claws into her sisters boyfriend.  Lauren seemed clueless, maybe she naively believed that sisterly affection would protect Jackson from her ravenously slutty bitch of a sister. If so, she was to be sorely mistaken.

Jackson was the first to arrive, and Kyler's wicked eyes lit up as the six-foot-two quarter-back strode into the room.  Uncaring that she was the only one dancing, she put on some music and began to twerk in the middle of the room whilst Lauren sat on the sofa looking more and more angry. 

"Kyler, what the fuck are you doing?" she hissed as Jackson greedily ate up the sight of his girlfriends hot white step-sister doing her thing.  

"It's a party I can fucking dance if I like," giggled Kyler. 

"You're ruining my fucking party, you're acting worse than even that whore Kayla.   You're going to ruin everything, please stop it."

"But look, your boyfriend loves my dancing," laughed Kyler as she worked her ass in the middle of the room and Jackson came up behind her.  His strong hands slid round her waist and she ground his ass into his crotch, taking care to make sure Lauren couldn't quite see how seriously she was rubbing up against his dick.

"Kyler!  I need you to stop, please!" groaned Lauren in despair as she watched her sister ruining her party before it had even begun.

DING DONG.

Lauren had no choice but to go answer the door, leaving Kyler and Jackson alone for a moment in the living room.

"Damn girl, your ass is fine..." smiled Jackson as his hands slipped down to touch Kyler's perfect little bottom.

"Mmmmh, you fucking want it don't you," she giggled playfully in his ear. "Come on, lets go to the bathroom whilst she's distracted."

Jackson wasn't exactly the most loyal of boyfriends.  He was an absolute dog for tight pussy and the offer from his girlfriends incredibly hot sister was too much.  They ran upstairs together, Kyler literally pulling him into the bathroom, such was her eagerness.

 

"Oh I've been wanting to fuck you for sooooo long," she giggled excitedly getting to her knees.  "I wanna see your big cock so badly."

"Take a look then baby," he smiled as Kyler eagerly pulled out his swelling manhood and with a delighted moan sized him up.  "Fuck, you're huge... I can't wait to play with this monster," she grinned and without any further ado took his dick into her mouth.

Jackson groaned happily, looking down at the tight little bitch sucking his dick.  She was beautiful and her big hoop earrings bounced as she sucked his cock.  Funny... he was sure that slut Kayla from school had a pair just like that.

"Mmmmmh, your cock is delicious and it's soooooo big," groaned Kyler after five minutes of vigorous slurping and sucking.  Please baby, I'm so wet... fuck me."

Jackson helped her to her feet and ripped down her leggings till they pooled at her feet.  Then bending her over, he positioned his fat dick behind her tight pussy and with a grin slid deep inside her.

"OHHHHHHHH FUCK!" moaned Kyler as her sisters boyfriend's dick slid soooooo deep inside her. She grinned and moaned, pushing her hips back as he began to fuck her.  Her earrings jangled as her fucked her and through the haze of pleasure she seemed to have a sudden strange feeling that there was someone else in her head enjoying this too.

Ooooh yeah, I can feel it too.  Mmmmh, I love being inside you babe. I knew Jackson's cock would feel so good. He's massive and your pussy is so tight. It's a match made in heaven, that whore Lauren is going to be sooooo jealous and mad when she finds out.

Kyler ignored the voice... it reminded her of her friend Kayla but that wasn't possible. How could Kayla be in her head? Instead she just focused on the pleasure building within her as Jackson fucked her deeper and harder than she'd ever known in her life before.

"Ohhhh I'm cumming!" she screamed as she wiggled her hips and pounded back faster and faster.  With a rising crescendo, she exploded... screaming and uncaring who heard as she shook and orgasmed in delicious pleasure.

"Fuck baby, you're gonna make me cum too," grunted Jackson unable to contain himself any longer.

"Yes! Cum inside me... fill my slutty pussy up with your jizz," hissed Kyler in wild abandon as Jackson obeyed her and unloaded inside her with a satisfied moaning groan of pleasure. Kyler enjoyed the feeling of his warm cum inside her... what a satisfying fuck that had been.

His warm cum oozing out her pussy, Kyler lay back on the bathroom rug and looked lovingly at the grinning Jackson.  But the smile was suddenly wiped from his face as the door exploded inward and a furious Lauren rushed inside.

"YOU FUCKING JERK," she screamed at Jackson sobbing hot salty tears as she beat her hands against his chest.  "HOW COULD YOU? SHE'S MY FUCKING SISTER!"

"Babe, I'm sorry - she's just so hot, I couldn't help myself," tried to placate Jackson, but it was no good as she screamed at him and threw a nearby plant pot that crashed against the wall.

"Bitch, you're crazy. I'm out of here," gasped Jackson, grabbing his clothes and leaping out of the room.  He ran off, with Lauren's screams behind him.  She turned to Kyler, tears in her eyes.

"You fucking bitch, you betrayed me.  How could you?  You've ruined my party and my birthday.  I can't even look at you anymore."

With a hot sob Lauren ran from the room and Kyler watched with amusement as she went.

Oooooh, that was brilliant.  Great work bitch, you turned out even nastier than I thought. That cream pie is fucking hot. Corrupting you into a slut was the best decision I ever made.  Lauren is furious.

"She'll get over it, we are sisters after all," smirked Kyler.  "Haha, but I guess I probably won't be invited to anymore of her parties."

Thats okay babe, whispered a voice in her head.  From now on we'll have our own hot girl popular parties and guess what... she is NOT invited.

Kayla's revenge... was complete.

THE END
