Stomping her foot, Hannah tossed back her head with a scream of rage and stormed out of the living room. On the way, she nearly bumped into a smirking figure by the door who was enjoying the show.

Hannah scowled as her little brother Eddie laughed at her. He loved watching her get into trouble and was such a goody two shoes. Pathetic little boys like him needed to stay out of her way.

She went to push him out of the way, but he ducked out of the way and stuck his tongue out at her.

What a little shitbag...

She'd show him to mess with her... him and her Mom!

Hannah decided she would get a piercing anyway. Once she had her belly pierced it would be too late for anyone to do anything about it and she didn't care if she got grounded so long as she got what she wanted.

She put on makeup and clothes to make herself look older and stormed down to the mall - but as she was too young to provide an I.D - no one was fooled enough to help her.

Sobbing outside a tattoo parlour, her mascara running, Hannah grit her teeth hard. Life was so UNFAIR. Why couldn't she just do what she wanted?

Suddenly she heard a laugh. A cool looking woman with pink hair and tattoos and piercings was leaning against the side of the shop eyeing her up.

"You gonna give up that easily bitch? I've been watching you all morning trying to get a piercing and failing. I was starting to admire your determination but now I see you're just pathetic."

Hannah stormed to her feet. "Fuck you! I'll get a piercing even if I have to do it to myself!"

The woman's eyes flashed with amusement and partial admiration. "Yes! That's more like it girl. Take what you want. Don't let anyone stand in your way. Bully and manipulate others to always get what you want. Sluts ALWAYS win."

Hannah gawped at her.

"I can see some real potential in you, so I'm gonna help you get EVERYTHING you ever wanted. I can give you an slutty magic piercing. Use it when you get home and it will turn you into a sexy eighteen year old bitch.  No one will even remember the old you - it will be like you have always been a hot popular slut. Your Mom will never be able to stop you again. You'll finally be the assertive, bullying, spoiled slut you dream of being and you will be able to get as many tattoos and piercings as you like. No one will ever stop you again."  

The woman produced a piercing from between her fingers and tossed it to the surprised Hannah. "Just put this into your belly button and let it bond with you. All your dreams will finally come true. Trust me."

Hannah slipped the piercing into her jeans pocket and with a muttered 'thank you' stumbled away whilst the woman watched with a smirk. Hannah truly believed what she had been given was really magic. There was just something so convincing about the woman.

The pink haired woman watched Hannah run excitedly away then turned and walked back into her tattoo parlour. "Evie's Place."

What happened next really wasn't her problem, she just hoped the girl enjoyed the gift she'd been given...

***

Hannah couldn't believe her luck. She wanted to believe in the magic so badly and be a hot older girl. The urge to put the ring in straight away was almost irresistible, but she wanted somewhere private to transform where she could enjoy her transformation. "Soon I'll be a slutty popular bitch and then NO ONE will stop me."

Hannah ran excitedly home, her heart pounding. She couldn't wait to try the magic piercing and get older and hotter.

Once she was a slutty eighteen year old she could fuck boys, drink alcohol and smoke. She would have a body that would make others jealous and would do whatever she wanted. She couldn't wait to be a slutty, spoiled bully and torment her Mom and stupid brother.

She could already imagine wearing the hottest skimpiest clothes, swearing and belittling people... getting tattoo's and maybe even her nipples pierced. It was going to be so fucking hot!

Bursting through the door to the house, Hannah grabbed the piercing and leapt up the stairs. A few more seconds and her dreams would come true.  She quickly ran up to her room, but in her haste failed to notice her brother Eddie was once again in the way.

This time he was too slow to avoid her and they collided, Hannah bouncing backwards and Eddie hitting the wall with an 'oof'. The impact caused her to fall onto her backside and the piercing leapt out of her hand and spinning in the air bounced onto the carpet in front of Eddie. Recovering quickly, he pushed himself off from the wall and he picked up the piercing triumphantly.

"Haha, Mom said you couldn't have one of these. I'm telling. You're gonna be in SO much trouble." Eddie was gloating, he loved having something to hold over his stupid sister.

Seeing the piercing glittering in her brothers fingers, Hannah suddenly felt the icy grip of fear. She had to get the piercing back at once from him, but she needed to play it down. If he thought for one moment it was really important, she'd never get it back. Taking it by force could be an option, but was risky. No... the subtle approach was best.

"It's a fake one you douche. Mom says I couldn't have a real piercing so I bought a fake one that stays in your belly without a pin. It's actually a worthless, cheap piece of shit. You're wasting your time, she isn't gonna care about it." Hannah tried to keep her voice calm.

"No! I don't believe you. I'll prove to Mommy you disobeyed her. Look - it doesn't stay in," sneered Eddie, sliding the piercing into his belly button to prove his sister wrong. 

"Noooooo" screamed Hannah - but it was too late as the piercing bit into Eddie's belly button and eagerly took root. He instantly transformed - a rippling wave of energy spreading out from the piercing and turning Eddie from a good boy into a nasty little slut and altering reality to create Hannah's bitchy older sister Ella.  

Bones cracked and skin tightened - his flesh tanning slightly as Eddie moaned and stretched pleasurably. It felt good to become a girl and he offered no resistance as big tits pushed out of chest, causing his top to balloon out and his little boy dick sucked away to become a tight eighteen year old pussy.  

Lying on the floor, Hannah stared up in horror at her transforming brother as his ass pushed out and he grew taller and sexier than she could ever hope to be.

Slutty white expensive nails sprang from each finger tip and every inch of hair on his body melted away to leave smooth tannedfemale flesh.

The girl above her was moaning and giggling in pleasure as her voice became rich and bratty.

"Oooooh what's happening... mmmmhhh it feels so good," she moaned as her short hair lengthened and grew out. Thick slutty makeup coated Eddie's once innocent face and naughty pink lips curved into a surprised look as his insides churned and he became physically fully female.  

"Ohhhh shit, I can mmmmh almost feel my ahhhh new uterus in there... oooh I'm a fucking girl and I like it! I feel so feminine. I can FEEL the estrogen pumping around me. Making me girly, making me like boys. Mmmmh."

Thick black lashes fluttered in pleasure as sexy blonde hair fell down around her shoulders and naughty blue eyes twinkled with the desire for sex.

This girl needed a new outfit and Eddie's shorts became a pair of tight white hot pants as his big tits were encased in a slutty pink top. Gold hooped earring dropped from his ears as his trainers turned into bitchy pink cowboy boots - just perfect to get fucked in.

As his clothes changed - Ella's personality rose inside him to take control. A bitchy voice giggled in his head and Eddie allowed it to re-write his thoughts, mind and personality.

Sinking into Ella felt good. Being older and sluttier felt so amazing. The piercing was making HIM the naughty bitch of the family. He wanted it all.

Hey little Eddie. Time to become me... mmmh time to be a bad, bad girl. You're gonna love having my pussy and tits and being a naughty little cock-sucking slut. Let me fill your head with memories of all the boys we gave blow jobs to and all that cock we swallowed.  Mmmh you love cum now don't cha bitch?  And getting fucked by a big cock... feeling it deep in that tight pussy. Mmmh you live for that now! Yes thats it... you're becoming me... ahhhhh good boy. Now cum and become me fully...

Shuddering in pleasure, Ella creamed her panties and the once pure and innocent boy became a spoiled bitch. His bad girly side was now dominating their body. Eddie was dead.

"Oh fuck  yeah - I am sooooo totally a slut now and I fucking love it. Yessss!" 

Giggling madly, Ella grabbed her tits and squeezed. She felt amazing. Being a naughty whore was such fun and she was never going to take the piercing off.  

Hannah shook her head like she was in a dream. The events of the last few hours were fading as reality changed so that she remembered nothing of her brother.

Looking at her slutty sister, Hannah felt nothing but disgust. "Eugh - why are you always acting like such a slut?", muttered Hannah darkly as she watched Ella play with herself.

Her sisters new personality had slotted into her own life and having grown up embarrassed and disgusted by her exhibitionist sister, Hannah was now a quiet little nerd girl. She no longer remembered she ever had a brother or that she had even wanted the piercing for herself.  

Ella did remember though - it amused her to think she had woken up this morning as a little boy. Being a hot bitchy slut was loads better and she giggled joyously. "Whatever sis. I'm off to my room for some real fun. You're SUCH a fucking loser."

Hannah had just picked herself up. She now had bottle top glasses and a preppy outfit on. Laughing, Ella tore the glasses off her face and ground them under a booted heel - then she pushed her blinded sister over again.

"Ohhh but before I go, if you ever call me a slut again in front of Mom and Dad I'll do worse than this you little bitch. Don't forget it."

Changed into something more casual and easy to rip off - Ella excitedly examined her room. It was a boudoir fit for a princess.

Calling her latest boyfriend on her expensive mobile phone, Ella examined her new bedroom as he made his way over. It was pink now. Pink, girly and slutty - just the way she likes.

She played with her blonde hair and admired her sexy new grown up body, lusting after herself.  Fuck she was hot.

When her bad boy boyfriend Jason arrived she didn't waste anytime. "Baby - I am so horny. I want you to fuck me... hard." 

Ella moaned and squealed as Jason threw her onto the bed and ripped off her clothes. His hand closed round her throat as he pushed deep into her tight bare pussy and began to pound her - causing Ella to moan and groan in pure ecstasy.  This was how she liked it... to be used like a whore.

"Yes... fuck me you stud! Pound my body with that big cock! I want it deeper... OHHHH YES"  

Ella loved being fucked rough. She watched her piercing glitter in her navel as Jason stretched her pussy out good. His cock slid in and out of her tight clinging pussy lips and her big tits shook as he fucked her hard. She wrapped her tanned legs around his strong waist.

"Cum in me baby... I wanna feel it fill me up."

Turning her head Ella giggled as she saw her door was ajar and the tear streaked squinting face of Hannah was watching her. It was so fucking hot to rub her sisters face in it. Hmmm maybe she should make the little bitch eat Jason's cum when he creampied her?

"Cum in me. Ohhhh fuck yessssssss." She groaned as he pumped so much into her it instantly flooded out down her tanned thighs.

Being a slut felt so fucking good...

THREE MONTHS LATER

"What's the matter loser?" laughed Ella as she pulled up next to Hannah on the sidewalk. "No friends to walk home with? I'd give you a lift but I'm on my way to the mall."

Of course Hannah had no friends. Ella had seen to that by bullying them all.

Since becoming a slut Ella had transformed her life and other peoples. She was now a spoiled toxic girly girl and so long as she had her magic piercing, no one could stop her. But her desire to corrupt others was now growing.

"I'm on my way to Evie's Place to buy some more piercings. I was thinking it's time to get Mom and Dad a present too. You know... I think Mom might enjoy a clit piercing. Once I get it onto her, she'll become the fake plastic neighbourhood homewrecker I know she can be. For Daddy - a cock ring and a cage. I can't wait to turn him into a simp."

Lauging, Ella threw some wrappers and trash she didn't want out of her car and into her sisters face. The shutting the door she drove on.
