Double Day (Quickie)

 Double Day

"Awwwww, did you get dumped by your girlfriend little brother?" laughed Gabbie as she sat on her bed and finished adjusting a white bra strap - the motion causing her massive tits to wobble, "that's too bad considering today is Valentine's Day."

"You bitch - you did this didn't you?  You told Alicia that I had an STD and had to be checked out at the clinic," screamed Todd in a rage as his evil sister laughed and ironically adjusted her Angelic halo, "She said she never wanted to see me again!"  

Gabbie giggled as she winked at him. "Awwww too bad, you can't prove anything you loser and now I get to enjoy Valentine's day getting railed by my hot boyfriend whilst you have to sit in your room and masturbate like a little simp. Now get the fuck out of my room before I tell Mom you're in here you pervert."

Gabbie and Todd had never got on and their rivalry was getting worse and worse by the year. Gabbie was by the far the meanest and most manipulative of the two and she had her Mom and Dad wrapped round her little finger - meaning she could pretty much get away with anything.  She loved to flaunt her female superiority in her loser brothers face and bullying him just got her wet.  The thought that she had ruined his Valentine's Day was so sweet to her and made what was going to be an amazing night even better.  

Pretty soon her boyfriend Jason would be coming round, just as her parents went out for dinner.  Then she was going to spend the night fucking his brains out and cumming all over his big dick.  She'd decided to dress up for the night - reusing some of her old halloween costumes.  She'd hung the costumes downstairs to wind up Todd, "Should I be an Angel or a Devil tonight?" she'd laughed as he fumed in frustration, leaving the sexy Devil's outfit hanging up in the kitchen to taunt him. Everything was shaping up perfectly for her.  She watched her brother leave and grinned as she admired herself in the mirror - damn she looked good tonight... this was gonna be a LOT of fun.

Meanwhile, Todd stormed out of his sisters room slamming the door behind him.  The fucking bitch had to pay - and as he made his way into the kitchen, he suddenly saw her Devil's outfit and a slow grin spread over his face as a crazy idea occurred to him.  Gathering up the sexy lingerie,  he plucked one of her long black hairs off the lacy red bra and carrying his treasure upstairs looked in his school bag.

The pills were in a bag where he'd stashed them... Dopplebanger - the new drug that was taking the country by storm.  Dropping a pill into a glass of water, he watched it fizz and then he dropped his sisters hair into the liquid.  It rapidly dissolved into the solution - turning the water slightly pink.  All he had to do now was drink this liquid and he would become a perfect copy of his sister.  He'd even get her memories and her bitchy personality... then he'd have some real fun.

Hearing his Mom and Dad leaving the house, he grinned and went back down to the kitchen. Swirling the Dopplebanger, he downed it in one go - gasping as the sweet tasting solution slid down his neck.  Todd hated his sister, but he was also kind of jealous of her and he was looking forward to becoming her for a while and finding out how it felt to be a slutty bitch.

He gasped as his body burned and ached... cracks and pops filling the room as he felt himself shrink and his hair began to lengthen.  Soft skin spread over his body as his ass pushed out and his sisters slutty features replaced his own, pink lips opening in a naughty pout as dazzling green eyes flickered in pleasure.

"Yesssssss, make me into Gabbie... it feels so good," hissed Todd as he allowed his sisters DNA to corrupt him and make him into her.  Every inch of him felt amazing as his dick began to shrink and retract between his legs, giving him his sisters perfect shaven pussy... tight and wet already at the thought of the fun to come.  He grinned lewdly as Gabbies massive breasts began to swell out and fill his waiting hands - bigger and bigger till he was a perfect copy of his bitch of a sister.

Coughing to clear her throat, the new Gabbie giggled as she looked at herself in glee.  She knew that she was really Todd, but that loser's personality and memories were being supressed by her own.  She glanced upstairs and smirked as she thought of the real Gabbie up there waiting for her lover.  The new Gabbie couldn't wait to teach herself a lesson...

Picking up the Devil's costume, she began to put it on... admiring how it fit her perfectly.  She headed to their parents room to borrow some of their Mom's makeup - she needed to be out of the way whilst Jason arrived and she couldn't very well use the real Gabbie's makeup - as much as she wanted to.  Being a girl felt amazing and she loved dressing up like a fucking slut... she was just as nasty as the real Gabbie and she couldn't wait to prove it.

********

Meanwhile, upstairs the original Gabbie was impatiently awaiting her lover.  Hearing the front door open, she arranged herself on the bed. She'd given Jason a key and instructions to come right up when he arrived, so she wasn't surprised when he walked in and grinning shut the door behind him.

"Wow," he gasped as he drank in his bitchy girlfriend, "You look fucking amazing."

"I know," purred Gabbie as she stretched like a cat. "It was either this, or my devil costume, but I thought tonight I'd be your innocent little slut.  I want you to corrupt me so much though and take my halo.  My Mom and Dad are out and my little brother can't stop us - come here and let me fuck you baby."

Jason grinned and walking over began to take down his pants.  Gabbie smiled at his big dick, this was why she was dating him, and she couldn't wait to play with her prize.

"Mmmmh, let me suck it," she groaned reaching out and running her hands over his delicious cock. Jason was just her sort of guy... super fit, but dumb enough to push around. In some ways he was the perfect boyfriend.

Jason was only too happy to let Gabbie slide his dick into her mouth.  She began to suck, the angel wings on her back flapping slightly and her tits wobbling as she enthusiastically slurped on his dick.  It felt really good, Gabbie was an expert cock-sucker and Jason was super hard as she blew him.

Gabbie worked her boyfriends cock expertly... spitting on it, running her hands over his balls and making perfect eye contact. She knew exactly how to taunt and tease him, biting the head - licking the shaft - glugging it down her throat.  She was such a slut, but she didn't care as she expertly brought Jason closer and closer to cumming.

Not that she had any intention of letting him cum yet.

Her white lace panties were soaking wet and her cunt was burning to be penetrated. She wanted to get fucked so badly and it was nearly time... any moment now she'd turn around and tease him with her pussy... then he would push inside her and the real fucking would begin.

BREEEEP, BREEEP, BREEEP!

"What the fuck?" cursed Gabbie as she saw her phone was going wild.  Grabbing it she swore as she saw a text message from her stupid brother. "Gabbie, Mom left her purse in her room and says you have to give it to me so I can take it down to her."

Gabbie swore, this was just the stupid kind of shit her brother would do to try and mess her about, but there was a chance it could be genuine.  "Baby, don't go anywhere," she smiled, "I just need to deal with something quick, then I'll be right back."

Jason obediently sat down and Gabbie made her way to her Mom's room.  Opening the door she flicked on the light and stomped in.  Then something hard hit her on her head and she knew no more...

**********************************************

Tapping his foot nervously Jason cursed and wished his girlfriend would hurry up.  He desperately wanted to fuck her and his cock was starting to go soft again.  He was just about to go look for her, when the door opened and she walked in... only now she was wearing a devil outfit.

"Hey baby," she grinned, "sorry about that - I had to take care of my dumb sibling."

"You changed?" he stuttered, "that was quick!"

"Well - I thought a devil might be more fun... now where were we.  Was I sucking your dick?"

"Yeah, you were, now get over here and get back to work," he grinned.

"Sure thing," she purred hopping on the bed and sliding his cock back into her warm, wet, mouth.

Jason groaned happily as Gabbie got back to work.  It was funny - but it felt slightly different... possibly even better than before.  Maybe the devil costume was bringing out his girlfriends naughtiest side.  He groaned happily and was soon rock hard again... but he had finally had enough of blow jobs. He wanted to be inside his slutty girlfriend.

"You ready to fuck babe?" he gasped as she slid his dick out of his mouth and giggled. 

"Ohhhh, you bet I am," she purred, sliding off her panties and revealing her bare pussy, glistening slightly with it's already wet entrance.  "I'm ready to get fucked good."

Lying back on the bed, Jason pumped his cock and grinned as his super hot girl positioned herself above him. She seemed a little hesitant for a moment, but then lowered herself down - and he moaned as she grabbed his cock and guided it into her tight, wet, pussy.

"OHHHH FUCK," they both gasped in unison as he penetrated her and his cock popped into her pussy with a delicious sensation.  She began to wiggle up and down on him, riding him like a whore as he groaned and felt the pleasure grow in his dick.

"Ohhhh this is so fucking good," groaned Gabbie, playing with her tits as she bounced on his dick. "I love this."

Jason had to admit something about all this felt... weird.  Gabbie's pussy felt as good as it ever did and his girlfriend was the hot slut he'd come to know... and yet... and yet he felt that she somehow wasn't her self.  If anything it just made it hornier for him.

Her big tits bouncing free of her bra, Gabbie rode her boyfriend and screamed as she began to cum.

*********************

Jason moaned as he reached his climax. 

It was thirty minutes since he'd started fucking Gabbie and her stamina and drive were as relentless as always.  Barely able to keep up with his horny girlfriend, he'd done his best to fuck her to her satisfaction, but he was starting to lose control and knew he needed to cum soon.

"Baby, I'm gonna fucking cum," he grunted as Gabbie orgasmed again and with a groan slid off him.

"Good, cum all over my slut face," she whined pumping his cock and giggling as he cummed all over his face.

It was at that exact moment that the door flew open and a Gabbie in an Angel costume staggered in clutching her head.

"You fucking bastard," she screamed as Jason's cum rained down on her Doppleganger. 

Jason looked at both girls in amazement, then his face fell as he realised what must have happened and the Gabbie in the Devil's outfit laughed like a bitch. 

"You fools, I got everything I wanted from both of you. The switch-around went perfect and your dumb boyfriend never realised it," cackled Todd as he licked cum from his face and smirked at his sister.

"Guess your Valentine's day didn't turn out as perfect as you hoped."

Revenge... was definitely sweet.
