"Wow..."
Jackie looked up in amazement at the towering beanstalk growing in her back yard. It had appeared overnight, after her mother, in anger, had thrown the beans she'd brought home out the kitchen window.
Jackie had gotten the beans in a trade with an old woman she'd met in the village market. The woman had promised the beans were magic, and would put an end to her family's money troubles for good.
Now, Jackie was looking at a massive plant, stretching up and up until it disappeared beyond the clouds.
"What the hell is that?"
Jackie turned to see her younger sister, Jill emerging from the house. She was staring up at the beanstalk too.
"Where's Mom?" Jackie asked.
"Still in bed, I think. Where did this come from?"
"I... I think it grew from those beans." Jackie replied. "The old woman said they would put an end to all our problems." She looked up into the sky. "I think I need to climb up, to find what's at the top."
Jill chewed her lip as she eyed the colossal plant. "Well... I want to come with you then. I don't want to be here and have to explain to Mom where you disappeared to."
Jackie frowned. "Alright, fine. But let's hurry, then, while Mom's still asleep."
And so, the sisters began to climb. The going was slow, at first, but the farther they went, the more they got used to the climb. After a few hours, they lost sight of the ground beneath them. As time wore on, their clothes became filthy, tearing in several places from thorns and branches jutting out along the stalk.
The plant was also excreting a thick green sap that got all over the girls' hands and boots. "What is this stuff, anyway?" Jill asked, sniffing the fluid sticking to her fingers. "It smells so sweet..." She hesitated for a moment, then gave her hand a tentative lick.
"Ugh! Jill, what are you doing?" Jackie asked.
Jill's face lit up. "It's good! It tastes, like... really good!" She started to lick it directly from the stalk, and seemed to be really enjoying it.
Jackie wearily eyed the stuff seeping from the plant in front of her. She gave it a sniff, and a cautious taste with her tongue. As soon as the flavour hit her, a wide grin creeped across her face. "Mmm!!"
She started to gorge herself alongside her sister, and the two girls ate as much of the syrupy fluid as they could. Once their cheeks and chins were coated in green sap, Jackie lifted her face from the plant and smacked her lips.
"We should get going again." she said. Jill didn't seem to hear, so she shook the younger girl by the shoulder. "Come on, Sis."
Jill finally pulled away, too. "Right. Ok, let's go." she said, as she sucked the sap from her fingers.
Jackie let her go first, and followed close behind. As she climbed, she looked up directly into her sister's crotch.
Jill was wearing a very short skirt, and it had been torn almost to bits by the beanstalk's sticky thorns. Jackie could see straight up it, and blushed when she realized her sister wasn't wearing any panties.
The sight of her sister's naked pussy made Jackie's body react. She was beginning to get aroused by her hot baby sister! Unbeknownst to either of the girls, the sap they had eaten was a powerful aphrodisiac.
It was making Jackie's body want things she'd never even thought about before. She found herself imagining what it would be like to bury her face between Jill's supple thighs, and the thought made her own pussy moisten almost instantly.
"Uh... Jill? I... I feel kind of... funny..." she stammered, uncertainly.
Jill was feeling the effects of the sap as well. She swung herself onto a large branch, sitting across it to look down at Jackie. She could see straight down her sister's torn blouse, and licked her lips as she eyed the older girl's cleavage.
"Er... I... I feel a bit weird too... Maybe we should take a break." Jill helped Jackie up onto the branch with her, and the two sat facing one another. Both girls found it impossible to tear their eyes from one another's bodies.
"Hey, Sis?" Jill asked. "My clothes are all torn up... I was thinking... maybe I... maybe I should just take them off."
Jackie's eyes widened and she looked up from Jill's breasts in surprise. "Um... I... Well, I mean...if you want to..."
Before she could finish her sentence, Jill was already pulling her blouse up over her head. Jackie licked her lips, and quickly followed suit, getting naked as well. Bits of tattered clothing fell from their perch until they disappeared into the clouds below.
Now completely naked, both sisters edged closer to one another. They were straddling the branch beneath them, getting more of the sap on their bodies. It smeared on their legs and into their spread open pussies.
"Jill... I... I never realized how... how grown up you've gotten..." Jackie stammered. "Would it be alright if I... if I..."
Before Jackie could get the words out, her little sister leaned forward, kissing her with unbridled passion. Jackie groaned, and almost immediately grabbed Jill by the back of the head, pulling her harder into the kiss.
Their bodies pushed tightly together, and Jackie leaned back against the thick trunk of the beanstalk, with her sister pressing firmly against her. They groaned as they made out hungrily, their hands groping at one another's writhing bodies.
The two sisters were stained from head to toe in the plant's green fluids, which drove their arousal even further. With apprehension thrown out the window, the sisters gave themselves over to their incestuous tryst.
Jill climbed into her sister's lap, and pressed her horny cunt down into her sister's. The two girls mewled in reaction as their swampy gashes jammed tightly together.
With a bit of fumbling, Jackie managed to pull one leg out from under Jill's, and they scissored their sap covered thighs. They clung to the plant for support, and the two girls started to fuck hard against one another.
