Sara sighed as she waited for her sister to leave the classes for the day it was just another day to her however her sister was very different she had seen one day when she went to go talk to her sister and saw she had a giant penis it was a huge shock it was her sister but she had a penis and a vagina at the same time she watched her sister masturbate and got herself off watching she wanted her to be her first but that was her twin. It was normally wrong to want that with your sister, it was against societies rules but she wanted her anyways. She spotted her sister waving to her as they boarded the bus heading to the stop by the house she continued to the house quietly sitting at her sisters side as they entered she smiled and went to her room. She could hear the shower running it seemed her sister was taking a shower as she removed her school clothing and blushed she wanted to think about her sisters large penis as she began to rub her panties thinking about her. She had some time while her sister showered as she began to massage her pussy it felt good her fingers sliding along her pussy lips as she removed hr panties and began to finger herself.

"Sister... I... want it in me..."

She said it quietly but she had also left her door open not thinking her sister would be out anytime soon. She slid two fingers inside her small frame as it felt so good she only wanted to feel her sister inside of her she did not care how morally unacceptable it was she wanted to feel her inside of her.
 
As Loreign stepped into the bathroom she set her book bag down by the door and began to unbutton her uniform with a relieve sigh. School had been rough on the fourteen year old, her hormones were raging and even during recess she had to stay seated the entire time or else she risked everyone knowing about her birth defect. It was even worse when her younger sister had been the one to ride home with her. Be it her sister or someone else, Loreign’s body didn’t know the difference nor care. A year ago when her best friend had found out was when she had first realized just what sex was, and in the year that followed she had become addicted to it.

Turning on the water to the shower she reached her hand in and immediately drew it back with a shiver, it was freezing cold. The heater always took a few minutes to get ready, so knowing it was only her and her sister home she picked up her bag and headed off towards her bedroom to put her stuff away. Passing by her younger sister’s room the smell of arousal flowed throughout her senses as she heard her sister’s quiet voice, calling out to her.

Peeking in Loreign’s eyes opened at the sight of her younger sister, of only a few minutes, frantically masturbating. “S…Sara?” She called out as she felt the blood beginning to pulse through her shaft, making her skirt bulge slightly as her panties barely contained the beast underneath.

Sara continued to masturbate as she heard her name called out looking over to see her sister staring at her she blushed a bright red as she saw her sisters hard penis almost breaking her panties away the cloth barely able to hold back the large penis inside. She looked over her pussy still wet as she had to think of what to say, she learned about sex about a year earlier as her father had sex with her he was a dirty man and could not keep his hands off of her but she always wanted her sister.

"I.. I... well... I... was doing things to myself I am sorry I did not close the door sister... you got to see your little slut sister fingering herself I am sure you don't want to see this body."

She wanted to hide herself but she already could see her wet pussy dripping there was no point in hiding it from her sister, she smiled as she knew what she wanted to say to her.

"I want you to fuck me sister... stick that giant penis inside of my pussy... I know you want to... fuck this dirty twin sister of yours..."
 
Loreign’s tongue slowly licked her lips as she looked at her sister’s fingers still inside of herself. She was hard and throbbing from the sight alone by the time she tore her eyes away and looked into the blushing face of her twin. Squirming slightly as she heard her little sister calling herself a slut she couldn’t help the small smile form on her lips along with her sister’s. “I hope dad broke you in like me… or else it will hurt.” She said as she dropped her backpack and stepped inside, locking the door behind her as she quickly climbed into bed with her sister.

Leaning down Loreign kisses Sara on the lips while her free hand moved down to pull her panties just low enough to unleash the seven inch shaft, something that wasn’t even fully engorged yet. Pulling her hips back she began to grind the length of it against the slutty snatch, rubbing the slick fluids all over it as it throbbed wildly and continued to pulse to even larger sizes.
 
She heard her sister mention her father breaking her in so he did it to her as well it seemed as she watched her sister move close she pulled her monster shaft out and began to rub it in-between her pussy lips causing Sara to moan it felt good sliding back and forth across her pussy as she watched the penis grow even bigger she was a lot bigger than her father was.

"It is so big... so father did it to you... as well... I see yeah he fucked me many times to many to count he always wanted to fuck my pussy... I guess he did you as well."

She moaned more as it grew even larger reaching its fully size sliding between the lips as it really really felt good her hips pushing back and forth to dig the shaft across her pussy lips. This was going to be fun as her hand went and began to massage her sisters small nipples grabbing in between her fingers and pinching it before letting it go.
 
It felt amazing to have her shaft grinding along her sister’s sex, pushing her lust to new heights as she rutted against her like a dog in heat. “Several… times… it felt so good, every night that mom’s gone I sneak in.” she said in a heated tone as she positioned her now 14 inch cock against her little sister’s slit. Leaning down she hungrily kissed her twin, forcing her tongue into her mouth as she slowly forced the 4 inch girth inside of the tiny girl.
 
So he had been with her several times that did not shock her as her sister continued to grind the shaft before she placed the tip into her pussy lips she slowly began to push it inside causing Sara to cry out in pain a bit before it began to slide further and further inside it filled her completely up as her belly bulged from the massive shaft sticking inside of it. She felt her sister push it in and back out and back in it felt amazing as she clinched her sheets getting used to the large size watching her sister plunging it inside of her made her moan quite loudly.

"That feels really good Loreign fuck me... ugh.... fuck me harder... faster... stick it deep inside of your slutty twin sister..."

She could feel the massive shaft hugging her walls sightly it felt good sliding back and forth she wondered if her sister liked how it flt she moved her sister as she moved her hand to rub her sisters pussy while her penis fucked her own.
 
Half, only half of Loreign’s cock had managed for squirm its way inside of her little sister and already her stomach was bulging underneath of the massive size. The sheer tightness of it was divine as the elder sister moved her hips back and forth to force the immense shaft in and out of the other girl. Her hands were on either side of Sara’s head as she rutted against her sister, moaning softly as she felt the small hand beginning to rub along her pussy. The encouragements of her sister and the heavenly feeling of thrusting into such a tight space while her pussy was molested was enough to make a single strand of drool drip onto her little sister’s face while her hips jackhammered her cock into her. Fifteen inches were now continuously slamming into the tiny girl, far more than any human could possibly take as it throbbed madly with desire. Each time blood pumped through it precum the size of a nickel would squirt out inside of her little sister, stretching her wider as the mushroom head easily penetrated into her womb.
 
She felt her sisters huge penis drill deep inside of her as she cried out in pain and pleasure her sister fucking her hard and fast the penis bulging her belly with each thrust as she moaned out in pleasure the feeling of such a huge thing inside of her was simply amazing. Her father was not nearly as large but this felt great as she moved herself to sit up and hold her sister tightly while the penis drilled inside of her body her small chest bouncing as her nipples were rock hard moving back and forth in front of her sisters face.

"I love you sister... this is amazing umph... don't stop fuck me your little slut sister... deeper... harder... cum inside of me sister... suck my tits sister..."

Her face bright red as she began to move her own hips up and down bouncing way up before slamming back down hard on her sisters cock it felt amazing taking the full shift back and forth inside of her body it fit tightly despite being fucked so many times by daddy.
 
Groaning from the pleasure Loreign’s mouth opened up as she took one of the tinny nipples in her mouth, suckling on it and nibbling as she slammed herself deeper into her little sister. It felt so good and before she know it Loreign felt the similar pressure building up inside of herself. Her cock throbbed as she slammed her entire length into her little sister, stretching her out to the fullest as she unleashed a massive spray of cum directly into her womb. A single blast filled it up half way, the second filled her up so much it began to ooze out around her cock, trying to escape. The third and final blast forced nearly a cup of cum out of her sister’s abused pussy, soaking into her bed as Loreign collapsed ontop of her little sister. Her body weight resting ontop of the massive bulge as it steadily forced more and more cum to ooze out of her.
 
She felt her sister getting more and more excited as she felt the penis throbbing it felt better and better before she would fill a rush of warm fluid fill her womb first spray filled her halfway the second all the way and the third gushing out all around them onto the bed as she arched her back releasing her own fluids mixing and causing a waterfall of fluids to spill out around the two but she was far from done as she turned her sister over and had her lay below before she began to move up and down herself taking the full length and slamming back down onto her sisters cock the cum squirting out with each thrust down.

"Oh god Sister more, I want more cum fill me up with your seed I want your baby sister keep fucking me you slut... feels good... oh god yes... fuck me sister..."

She moved her fingers to her sisters pussy below the penis and began to slam four of them inside hard as she could she would make her sister feel the best of both worlds as she bounced up and down eagerly accepting each drop of cum from her sisters penis.
 
Gasping softly as she suddenly found herself forced onto her back Loreign looked up at her sex crazed sister as the girl hungrily bounced herself up and down on her massive cock, not even able to fully lift herself off of it due to the massive size. Leaning back she closed her eyes and moaned with pleasure as her still hard cock had her slutty sister using her body like a sex toy, the pleasure of the still tight pussy wrapping around her kept her body in a state of constant bliss. Her mouth began to lewdly drool as she felt four of her sister’s fingers pushing themselves into her soaking wet pussy, stretching the well worn hole open as her penis throbbed harder and sex craved hole clenched down around her sister.
