Demon Seed 4

Rana didn't want to wear panties, but Naryn told her to wear pink ones. She didn't have any, but raiding her mother's closet produced some. She grinned at the realization her mother was now her slave.

Her new slave. Really, she was Lucas's, but Rana hoped Mama got used to the fact she was going to be the Bell family fuck toy indefinitely. Part of the young woman hoped that despite all her mother had done, that being a fuck toy would fulfill her. Not that it would change anything. Every time Rana felt guilt welling up inside her, her thoughts and heart turned to Lucas.

She was going to have Lucas's first child, the first of many. Guessing Lucy would be next on the breeding list, she thought convincing her older sister to submit willingly would be the path to earning a womb tattoo of her own. Rana found the idea of her older sister having a womb tattoo like hers hot.

Her tattoo tingled in a way that let the young bookworm know Lucas was enjoying himself. Shivers criss-crossed over her body as she wondered both what and who he was doing. She sighed.

Rana wasn't sure who was going to show up first; Lucinda or Naryn. She knew today was Lucas's birthday, and he deserved a gift. Rana wanted to give him Lucy, wet and ready for him. The demure, submissive wanted to watch his younger brother dominate their older sister. The possibilities turned her on. As she showered, her hands explored her aroused body, enjoying the warmth given off through the womb tattoo, making her pussy tingle and writhe.

She was surprised her mom had a wearable pair of panties because of their different body types. Rana was a petite triangle shape, whereas her mother was a straight hourglass.

"Hey, anyone home?" Lucinda yelled from the foyer.

Rana squealed in delight at the sound of the voice, running down the steps to hug her older sister. Lucy was quite similar in build to her mother, possessing the same statuesque figure. She wore a long-sleeved asymmetrical wide legged jumpsuit, highlighting both her incredible ass and generous bust. Mysteriously, she didn't seem to possess any baggage.

Rana, of course, wore a red floral mini dress that showed off her shapely legs and petite, pear-shaped ass. She loved the feel of her sister's body against hers when they hugged. It wasn't like she had never considered her sister as a sexual companion, but since falling under her brother's spell, she was constantly seeing things from a sexual perspective. Lucy was extremely bangable.

"Where's the birthday boy?" Lucy asked, relinquishing the hug on.

"Running an errand with Mom," Rana said. "Where's your luggage?"

"Still outside, darling," Lucy said, her voice containing an air of caution. "Where's the Momster?"

"Out with Lucas. Apparently, there's a yacht nearby," Rana answered.

"Of course, there would be. I'm going to get something to drink. She hasn't done away with the bar yet, has she?" Lucy asked tersely as she turned to bring in her luggage. Rana helped with a few bags.

"How have you carted around all these bags?" Rana asked curiously. There were four large travel bags on the front porch.

"I just bat my eyelashes like this," she said coquettishly before performing the flirtatious act to an imaginary audience. "Viola, men do whatever the fuck I want. It's time to make some Bloody Mary cocktails, darling. Let's get wasted before the Momster gets home."

Rana laughed. "Once you get settled in, meet me in Mama's office. I'd like to show you some stuff."

"Cutting to the quick, little sis," Lucy nodded. "I love it. See you in fifteenish."

Rana steered Lucy through the expository points of their mother's network.

"I knew most of it already. I suspected she handled what happened with the Disciples of More."

"Is that the name of the Cult you were with?" Rana asked.

Lucy smiled. "You have been busy reading. It's all down there except the finer points, which would entail me wanting to get to know myself better. It's kind of hard to explain, so I'll spare you the details. Let's chalk it up to another one of Mom's attempts to take control of my life." The tall, dark-haired beauty sighed. "Fuck that bitch."

Rana nodded. Concentrating a little, she waited until her sister locked eyes with her before she used the Dialect.

"Lucy, I want you to trust me."

It was a simple command, which Rana wanted to stick to the most since she didn't want to push her ability with Lucas's demon-kissed ability.

"Okay," Lucy said, under her sister's momentary thrall. Rana let the moment pass. She was curious about her sister and wanted to know as much as possible.

"Lucy, are you seeing anyone right now romantically?" she asked.

Lucy looked at her sister. "The world is my sexual partner, darling. I like to keep my prospects wide open."

"Just men?"

Lucy grinned, taking a sip of her Bloody Mary. "The world doesn't just have men in it, dear. The best lay I've ever had to date was a woman. Fun fact-most Olympic athletes will fuck anything with a pulse as long as it's hot."

"And you are hot, big sis," Rana agreed.

"I am indeed. But how are your romantic prospects, if I may ask?"

Rana went for as much honesty as possible.

"Pretty nice, Lucy."

"Oh my, I can tell you've been to the promised land. Tell me, is it Lucas?"

Rana's gasp made Lucy laugh good naturedly.

"C'mon, sis, I know you had a thing for him. I don't judge. I just never thought the Momster would ever let you consummate your relationship."

Rana looked at her sister. "Mom actually watched while Lucas fucked me for the first time."

Lucy almost dropped her drink in surprise initially, but wasn't put off by her sister's lewd admission.

"She watched Lucas fuck you?"

"Oh, Lucas didn't just fuck me, Lucy," Rana admitted, her voice husky with lust. "He put a baby inside my body. He deflowered and bred me in the same incredible fuck." She sighed for emphasis, her nipples hardening like rocks, remembering the feel of her brother's organ up her vaginal cavity.

"Holy fuck," Lucy said. "That's where this whole thing is going, then?"

Rana flushed a bit. "I haven't thought about the future all that much, but I know that having Lucas's children makes me want to finger myself."

Lucy leaned forward in her chair. "Fuck, Rana, show me, then."

Rana liked where this was going and took her sister's dare.

They were still in Meredith's office, but it was a plush room, with windows leading to a railing outside that overlooked the backyard pool area and had a commanding view of the bay. The office had all the creature comforts a home office provided.

Rana stood up, shimmying her pink panties halfway down her legs. She flashed Lucy her shaved bush, but not the womb tattoo. Still, her older sister grinned in appreciation.

"Rana, you always were a real sugar shorts."

"If you're referring to something both sweet and saucy, that'll do," Rana said, leveling a seductive gaze at her sister, who seemed to waiting in anticipation.

She moved the chair closer to Lucy. She wanted to be close enough so her sister could touch her if she so desired.

Rana played it like a game, slowly, seductively unbuttoning the front of her floral dress, revealing her size B's, nowhere near the size of her older sister's tits, which were in the C to D category.

The sisters were close enough that Rana put her left leg up on the armrest of Lucy's chair. Whereas Lucy's body was long and lean, Rana's was curvier, more compact.

"Oh my, darling," Lucy said, her own voice dripping with lust while her sister gave her a commanding view of her lower lips. The puffed-up folds of her sister's labia were engorged with blood, revealing her arousal.

Rana was shocked how much this was turning her on.

"How many fingers do you want me to use, Lucy?" Rana asked.

"Start with your thumb," Lucy said, her voice an explicit command that made the younger sister's pussy flow with extra juice. Dominating was fun, but subservience was her natural state.

Rana responded by moving her hand down to her thigh, snaking its way up to finally her moist vulva, where she experimentally rubbed, revealing to her own sister how turned on she was as her fingers became more and more saturated with her own love juice.

The younger sister whimpered as she teased herself, mainly watching Lucy's reaction. She couldn't help grin when Lucy began unbuttoning her jumpsuit to get at her own crotch.

"How did you get so fucking sexy, Rana?" asked Lucy.

Still grinning, Rana said, "Since Lucas filled my cunt with his gravy, I think he made me into quite the eager slut," she moaned softly.

"Speaking of filling, why don't you do what I asked and stick your thumb in your cunt," Lucy said, "Like the eager slut you are."

Her thumb entered the depths of her ready snatch, accompanied by an intake of breath from the demure young lady. Her eyes narrowed to half lids, keeping her aroused older sister in her sights. It was only fair that Lucy showed off her cunt.

But she wouldn't. Content to finger herself from within the confines of her jumpsuit, Rana couldn't tell if she was teasing.

"Can I see your pussy, Lucy?"

Lucy smiled. "You dirty little whore. You wanna see your big sister's juicy cunt?"

Rana nodded, corkscrewing her thumb into her own wet pussy, making sure her sister saw the glistening thumb.

"Please show me," she said, voice pleading. "Show your little sister how juicy that cunt really is. Can you do that, please?"

The tall, dark-haired stunner undid the top half of her jumpsuit, revealing a pair of nice, C-sized knockers confined in a white lace bustier. While similar in shape to Mom's, the areolae were smaller, nipples more pronounced. They rode only slightly higher, thanks to their 17-year differential. She wore a pair of vanity fair string bikini panties that were sleek and sexy on Lucy's statuesque frame. Rana was surprised that her sister kept a hairy bush down there; she remembered her sister was into shaving.

The jumpsuit came off in less than ten seconds. She tossed the clothing to the side nonchalantly while kicking her black casual dress shoes unceremoniously into the corner before sitting back down. Her hand vanished under her panties as she stared first teasingly at Rana, then with lust at the lewd masturbatory show she put on.

Rana stuck her lower lip out in sad frustration. Her brow creased in a mixture of lust and sadness.

"You're so mean, Lucy. What do I have to do to make you show me your pussy?"

Lucy answered by putting her leg up on Rana's chair, so now each sister had a leg on the other's armrest. Rana noticed how shapely her foot was. She wore an ankle chain and her toenails had been painted blue in the last week.

"Show me how dirty of a whore you really are. Suck on my toes, little Sis."

Rana smiled, checking out her sister's wiggling toes before eyeing her sister seductively. "Okay."

Wanting to give her Lucy the best show possible, Rana moved slowly, her eyes going from toe to Lucy and back again, until her lips closed around her sister's big toe as Rana's eyes looked seductively back at her in a submissive, pleading look.

"Rana," Lucy whispered. It was like a direct current went from big toe to her weeping sex. She couldn't believe how fucking debauched her cute little sister had become. Lucy couldn't believe how much it was turning her the fuck on. "That's it, suck it, whore."

The taste of Lucy's feet spurred Rana on, her hips gyrated in quick circles around her fingers. She had abandoned the thumb for index and middle fingers, pumping them into her eager cunt. With a loud slurp, she came off Lucy's pinky toe.

"Please take your panties off, sis," she said pleadingly as she batted her eyelashes. There was no doubt Lucy's fire was stoked, but Rana wanted to see her hairy pussy.

She couldn't believe how easy it had been! All she had to do was command her sister to be trusting, and it was going to lead to sex between them.

That question became more apparent as Lucy moved her other out over Rana's on the arm of the chair, demonstrating Lucy still had some flexibility from her days as the head cheerleader in high school. After that, she moved the gusset of her panties to the side, giving Rana what she craved; a look at her older sister's gorgeous hotbox. Tongue fucking until her jaw ached was the least of the disgusting things Rana wanted to do to her sister's cunt. Lucy pulled at her dark fur, stretching it out while her other fingers dug into her molten hole. Things sounded sloppier by the second as the sisters were on their way to tandem orgasms.

"You're gonna make me cum, little sis."

"Mmmmmmmmmmmhhhh!" Rana's head bobbed up and down as she blew her sister's big toe like it was the second-best cock she'd ever had. Her fingers squelched into her own sex and her hips moved like they had a mind of their own.

Feet away, Rana's wanton display of sexuality triggered Lucy in the best way imaginable. Fluttering into her lady garden, her fingers dug and scooped, inducing spasms that spread throughout her body like ripples on an orgasmic pond.

"Cumming," she said, giggling insanely as the raven-tressed beauty's body jumped and twitched.

Rana loved watching her sister's cum-face. It was less dignified than mother's; more indicative of what a true whore Lucy was. The petite bookworm's own orgasm careened through her body as she took her mouth off her sister's foot.

"OHMyGOD!" Rana yelled as she felt her cunt cream sploosh into her own hand.

For the next thirty seconds, labored breathing and satisfied whimpers filled Meredith's office as both sisters came down from epic orgasms.

Rana moved first, slipping out of her bra, while moving towards her sister, who put out her hand. The petite bookworm had no way of knowing if Lucy was trying to stop her or not, so she did what any good whore would do and began sucking on the wet digits.

"Oh Fuck, Rana," Lucy said breathlessly before grabbing Rana's hand and sucking her glistening thumb. Sister tasted sister for the first time. Wet sucking noises followed by sultry stares led to both women repositioning into more forbidden mouth-to-mouth territory.

A deep, passionate soul-kiss began as the sisters reveled in their newfound dynamic. For Rana, it was merely the continuation of what had been an incredible day with more carnal promises to come. For Lucy, it was a cliff she willingly leaped from, free-falling into sexual depravity as she willingly embarked on a sexual relationship with her own sister. That it was so wrong drove her ever onward.

Finally, it was Rana who broke first, her lips smeared with Lucy's lipstick, gazing into her older sister's lust-filled eyes before asking, "Mom's bedroom?"

Lucy purred, hands roaming over her sister's taut body as she responded. "Only if we can sixty-nine."

"Okay," Rana said, grinning like a Cheshire cat before the pair played tongue-hockey yet again, rising and clumsily moving towards their mother's room, pushing each other up against walls, hands groping each other's bodies as they took off the rest of their clothing. By the time they got to the room, they were both naked, clothes left behind on the floor like a trail of sexy breadcrumbs.

Rana pushed her older sister onto their mother's bed. The pair both squealed, rolling around as they passionately kissed. Lucy tried to drive, but the younger sister was having none of it, using a combination of her already previous night's debauchery and her own enthusiasm to gain a physical advantage over her older, taller sibling, still in partial shock over the unforeseen turn of events.

Long dark hair splayed with Blond as Rana began kissing her way down her sister's long, sinewy body, adoring her tits, spit shining those magnificent orbs, biting her nipples.

"Oh god, suck my tits! Use your teeth, sis! Ah!" Lucy cried, urging her sister onward and downward.

Rana's hands continued caressing those fat tits until her cheek dragged against her sister's dark mat of pubic hair. Using a hand, she pulled on the hair, stretching her sister's twat, inducing a yelp of enjoyment from the tall brunette.

"Lick my pussy, you dirty whore sister," Lucy said, eying her sister. Rana slurped her way around her sister's cunt, making eye contact before driving her tongue into the folds of her labia. Propping herself up on an elbow, Lucy moved a hand down to Rana's head as she began munching on her sister's cunt like it was a porterhouse steak.

Lucy was lost to the feeling as her baby sister ate her out like no one else ever could.

"How did you get so good at eating cunt?" she asked. It was like her body was a musical instrument that only Rana knew how to play. Lucy was at the mercy of her younger sister as she dutifully, and with a combination of enthusiasm and skill, worked to bring her to a gargantuan orgasm. With both hands wrapped around Rana's head, Lucy fucked her sister's tongue like it was the best cock ever.

As her older sister recovered, Rana moved up her incredible body, pleased by her handiwork. She didn't have to ask. Lucy showed her by sucking on Rana's tongue and kissing and licking her cum-drenched lips.

"Beginner's luck," Rana said, finally answering the question.

Lucy cackled. "I need to pay you back, little sis." With that, she kissed her way down Rana's body, enjoying her sister's breasts. She loved their shape of her sister's plump tits, and their taste. She didn't spend long on them, however, electing to move south.

"Love the tattoo," Lucy said appreciatively. "You are such a total whore."

"Said the girl ready to eat her sister's cunt," Rana said in a sing-song tone.

Lucy couldn't agree more. "Aren't we a pair of sister sluts!"

"Total whores," Rana agreed. She was going to say more, but the tongue on her labia seemed to take away her voice. The tables turned as Lucy showed off her cunt-munching skills to her appreciative sister, swiveling her hips around and over her older sister's tongue as it darted in and out of her molten fuck channel. Rana's hips had a mind of their own, churning around Lucy's hungry tongue.

Rana's hand found Lucy's, and they held each other tightly as Rana laid back, eyes closed, her hips bucking as her pussy ground against Lucy's chin and mouth as the older sister seemed like she was trying to jam the entire lower half of her face into her sister's vaginal canal.

Whimpers, wet slurping noises, and the musky scent of arousal filled their mother's bedroom. Finally, Rana just couldn't take her sister's oral assault anymore and drenched Lucy's face with cuntcream. Her cries subsided into plaintive whimpers.

Lucy moved up her sister's body, a sheen of sweat covering the pair. Rana's body was weary, but her mouth was lively as the two made out with passion, their faces covered in an erotic mixture of saliva, sweat, and girl-cum.

There was movement from the doorway. "What do we have here?" Lucas asked.

"Oh my god," Lucy started, defensively wrapping herself up in bedding to cover herself from her brother's prying eyes. "Knocking is a thing, you fucking ninja!"

"Heya Lucy," he greeted her from the door. Rana got out of bed like it was no big deal, running over to Lucas to give him a big hug. Lucy watched as her younger brother kissed Rana on the lips, sucking her tongue. He palmed her bottom, squeezing roughly. It was like she was trying to mold her body into his.

"Happy Birthday," Lucy said, embarrassed. Suddenly, her eyes bugged out. "Where's mom!?"

Lucas and Rana exchanged serious glances for approximately four seconds before they began laughing.

"What's the joke?" Lucy asked, clearly vexed.

"Mom's in the hallway, ten feet that way. I had her pick up your clothes. She can join if you want."

Seconds passed before Lucy yelled out, "WHAT THE FUCK IS GOING ON?"
