Pandora's Box

Chapter 9

Luan wasn't sure what was more unbelievable, that her mother had gone through her things and learned her most deeply held secret or the spiel about Lincoln being in love with her and with similar interests. It almost felt like a prank she might play on her sisters to see them grimace and squirm. But something inside told her otherwise.

The ride home was mostly silent, as were the hours intervening the time they arrived and dinner. For the most part, Luan remained in her room, pondering the new developments and how she felt about them. She'd had a crush on Lincoln as long as she could remember but had set it aside in favor of something more acceptable to others.

Even if Luan had been able to approach Lincoln, considering his youth and their familial relationship, she would've never done so with her extreme anal fixation in mind. It seemed doubtful that Lincoln might return her feelings, let alone share similar sexual perverseness. However, her mother had little reason to reveal something like that.

It seemed more likely some reprimand or punishment would be sufficient for her carelessness with her diary. At the very most, an embarrassing discussion about sexuality, regarding her anal predilections. However, her mother had forgone that, choosing to unload something almost as perverse on top of fondling her at the restaurant.

Her mother's touch still lingered on her aroused clit, and one of Luan's hands dipped into her skirt while the other massaged one of her nipples as she lay, spread-eagle on her bed. She had only worked herself into a frenzy when she heard her mother's voice calling from downstairs, announcing dinner.

"Kids!" called Rita as innocently as ever, reminding Luan how devious she'd been earlier. "Dinner is ready! Come and eat!"

What her mother told her had to be true. There was no other reasonable explanation for such a stark change in her demeanor. If Luan was right, that meant one thing, Lincoln had feelings for her. Smiling to herself, Luan pulled her hand from her clothing and straightened them, a sly plan to test her theory formed in her mind.

The first part of the meal went by the book, and Luan merely engaged in idle conversation while studying her family. Her mother seemed like another person, as if their outing that morning had never occurred, and Lincoln was busy talking to either Lisa or Lola, who sat to either side of him. Nothing seemed out of place.

It wasn't until a moment when everyone focused on their plates that Luan glanced at Lincoln from under her brow and bangs, and her heart nearly stopped altogether. Lincoln was staring at her with an awkward grin on his face. For a moment, she froze, her fork dangling from her hand. Then, she hid her face when he gave her a quick wink.

"It's true..." her brain told her. "And he knows... mom must have told him..."

While Lincoln thankfully returned to his meal, the next several minutes were almost unbearable for Luan. Squirming in her seat, she often shifted, giving the impression she was highly uncomfortable. But slowly, the resolve she'd mustered earlier reasserted itself, and she finally decided to enact her test, which then seemed little more than confirmation.

Giving her attention to the remainder of her food, Luan shoveled the curry chicken into her mouth. But, under the table, things were a different matter. Sitting directly across from Lincoln, Luan slipped her right foot from her mary jane's and felt her way toward his leg. When Lincoln smirked with no objections, she raised it higher.

Upon reaching Lincoln's lap, the boy held Luan's foot with his free hand and guided it to his crotch, pressing it tightly against his erection and rubbing it along his length. There was no mistaking his intent, and Luan's cheeks gradually began to flush. Despite her usual ability to eschew embarrassment on the stage, it had abandoned her.

"Lu?" their father piped up, one eye cocked in concern. "Are you alright?"

"Huh?" snapped Luan, immediately righting herself and sitting up. "Y-yeah... I... sorry. I was only thinking about Benny."

Furrowing his brows and pressing his lips together, Lynn sighed but returned to his food. With a house full of girls, such moments were frequent. Too frequent for Lynn's liking. And while his older daughters prepared him for it, they always took him off guard. It seemed they relished in making him uncomfortable.

"Excuse me," announced Luan moments later, standing and spooning some creamed corn into her mouth. "I'm not feeling well. I think I'm going to get ready for bed."

"Okay, honey," chirped Rita, smiling slyly at her daughter before anyone could object. "You're excused."

Luan stared at her mother momentarily while everyone else gawked at her as she stood there. Dinner was family time, and for one to get excused so readily was nearly unheard of. Spinning on her heels, Luan moved upstairs as quickly as possible. She had no intention of sleeping and very little time to prepare.

Luan's thoughts seemed unassisted, and her body acted on autopilot as she gathered what she needed. Perhaps it was her mental training for the drama club and her stints as a comedienne. Maybe it was the realization that a long-held desire might soon be satisfied. Either way, she moved like lightning across a dark, cloudy sky.

After arranging several things on her bed to resemble her sleeping form, Luan covered them entirely with her blankets. Next, she taped a quickly hand-written note to the bottom railing of the top bunk that read, "Do not disturb." Finally, she stripped and tossed her clothes into the hamper before donning nothing but a skimpy, sheer yellow nighty.

After listening intently at her door to ensure dinner was still in progress, and nobody else had left, Luan snuck out of her room, down the hall, and into Lincoln's. Once inside, she grinned broadly, clasped her hands tightly at her waist, and bunched her shoulders with glee. At last, Luan turned off the light and slipped into her brother's bed, snuggling against the wall.

While Lincoln wasn't entirely sure, he had an idea of what his funny sister had in mind. It wasn't likely she'd come on to him the way she did, only to chicken out. That wouldn't have been like her. Luan was, perhaps, one of the boldest among his sisters, always ready to face crowds and make a fool of herself doing so.

Then there was the knowing look their mother had given his sister before she left the table. While nobody else had any reason to believe their mother wasn't just being considerate, Lincoln knew better. It was only a matter of days ago that he and his mother fucked in the basement, leading to their adding Lisa and Lola to the mix.

While he hadn't screwed Lola yet, he had bedded Lisa, hoping to get her to join them in their private filmmaking endeavor. Naturally, after getting laid, his scientific sister had agreed to do their editing. However, they still needed Luan for the lighting and filming. Of course, he'd ensure they all got turns once everyone knew how everything operated.

However, Lincoln was in no rush to head upstairs. At least, he had to appear that way. So, instead of rushing off, he helped clear the table like always, then silently excused himself. After an early trip to the restroom to avoid the line later, he slunk off to his room, declaring his intent to turn in early, claiming he'd had a long day.

Walking into his room, lit only by the shafts of moonlight streaming through the small, circular window on the wall, Lincoln began silently stripping. He could hear Luan's heavy breathing, and his already hard cock throbbed in his underwear. Peeling them off last, he tossed them onto the bed toward his sister's head.

"A gift?" Luan whispered, her breath deeper and huskier than he'd ever heard, followed by an unseen sniff.

"Mmhm," hummed Lincoln, his silhouette barely visible to Luan. "A teaser of what's to come..."

Then, without further words, Lincoln slipped into bed beside her. He knew why she was there and wasn't about to disappoint. His mother had filled him in on her particular perversions, and he relished in the thought of ramming his hand up his sister's asshole, but not before he fucked her senseless.

Luan stopped her frantic diddling and drew her arms up, along with her nighty, when Lincoln touched her stomach, gently caressing her skin in small circles. And when he began moving it down toward her petals, her breath hitched. All those sleepless nights, thinking of her brother in place of Benny, were about to come true.

Sighing with pleasure as Lincoln's fingers slid between her engorged mound and graced her clit, Luan palmed his cheeks and pulled him into the most sensual kiss he'd ever received. Luan was older and more knowledgeable than either Lola or Lisa, at least in terms of sexual expression, and he would have to up his game if he expected to convince her to join them later.

For now, it was just them. Lincoln had Luan alone and naked in the room's darkness, just where he wanted her. Should she change her mind and flee, he could claim she tried to rape him. As he was younger than she, nobody would doubt him. However, that would hopefully not be the case. They needed her, and right now, he did too.

"Fuck..." muttered Lincoln with astonishment. "You're so wet and loose..." he said, nearly comparing her to Lisa before he caught himself.

"Just getting ready for you, Lincoln," cooed Luan, smiling lovingly up at him. "I don't know how much time we'll get, so I wanted to be ready."

After thoroughly soaking his hand in his sister's cream, he brought it up and sucked on two fingers, closing his eyes and moaning. He then offered her the other two, slipping them into her eager mouth. Her taste was unreal, and it made Lincoln crave more. While there was something delightful about Lisa's prepubescent snatch, Luan's was mature and full of arousing hormones.

Silently, Lincoln moved under the covers and positioned himself upon his sister's long, thin legs. Leaning in, he began kissing her pubic mound, slowly moving up her belly to her chest. Soon, his warm, moist lips wrapped themselves around her left nipple, and he began suckling on it with reckless abandon, sure to leave a mark.

Luan's hands instinctively latched onto her brother's head, kneading themselves into his hair as she pulled him tightly against her breast, moaning softly in the moonlit room. Lincoln encircled her teat with his tongue, occasionally biting it and rolling it between his teeth, sending massive amounts of fluid gushing from her cunt.

After Lincoln had thoroughly doused her tit, he moved to the other and precisely matched his previous actions on the small, untouched globe. Then, finishing his oral seduction of his sister, he proceeded further upward, kissed her neck and cheek, and finally, locked lips with her again. And, as he moved upward, the bulbous tip of his rod pressed against Luan's flower, waiting to be pollinated.

Lincoln braced himself on his elbows, one on each side of Luan's precious face, and he slowly began pushing into her as she gasped, wrapping her arms and legs around him. Burying his face into her neck, sure to leave a whelp, Lincoln thrust himself entirely inside his sister. Without hesitation or concern for what Luan wanted, he immediately began a brisk routine, ramming himself inside her and quickly pulling out, only to repeat the process as she writhed beneath him.

"Oh, God, yes..." Luan purred into Lincoln's ear, urging him on as his glans threatened to tear a hole into her uterus. "Fuck me..." she begged as she raked her nails across his back.

For his part, Lincoln remained silent, intent on giving his sister the plugging of her life. There had to be no doubts remaining in her when they finished, no chance of regrets or returning to Benny. Luan had to know she was his, and for untold minutes they rocked upon his bed as if they were the only two people in existence. Thinking ahead, Lincoln had wedged his spare pillow between the headboard and the wall to reduce any aural evidence of their union, and the only sounds were theirs.

Lincoln didn't know what had come over him. Perhaps he was getting more comfortable with what he was doing, and maybe it was his recent experiences with his mother and Lisa. Still, Luan came three times before he finally felt that tight pull on his balls, just before he exploded into her, filling every nook and cranny she had, like he'd been saving it for years.

"Whew..." sighed Luan, letting her arms and legs fall limply to the bed. "Holy shit, that was good."

The sheets had become entirely damp, not just from bodily fluids but from the profuse sweat coming from Lincoln and Luan. But, as Lincoln drew his legs under him and sat up between his sister's legs, the covers fell to the foot of the bed, gracing them with the night's cool air.

"We're not done yet," whispered Lincoln, his eyes fully adjusted to the dark. "Roll over," he quietly urged, moving his finger in a circular motion.

Luan's eyes lit up, and her cheeks flushed. She remembered her mother insisting Lincoln was into anal exploration as she was, but part of her still doubted. And until that moment, Luan prepared herself her partial satisfaction. However, with Lincoln's sense of urgency, she reconsidered. Only, there were still things that could go wrong.

"A-are you sure?" she murmured as she began to turn face down. "What if I'm..."

"Lu..." the fixated young man deeply purred as he lifted her butt off the bed while pressing her belly firmly against it. "I honestly don't care," he informed her. "If I get dirty, you can lick me clean after."

Luan swallowed with difficulty. It seemed her mother's words rang true, and Lincoln's appetite for raunchiness matched her own. Still, cleaning up in the dark might prove difficult, and Luan hoped she was clean for once, unlike when she anally masturbated while in the shower, something she jokingly referred to as 'assturbation.'

Hooking his left hand around Luan's left thigh, now supporting her hips, Lincoln kneaded his right between her folds, coating himself with a mixture of their fluids. Then, as Luan reached between her upright legs and spread her ass cheeks, Lincoln beheld her loose, pink pucker.

"I..." said Lincoln in feigned hesitation. "I don't know..."

"What?" gasped Luan. "No fucking way. You can't lead me on like this and not go through with it. Please?" she begged. "I'll do anything!"

Having heard the magic words, Lincoln cupped his fingers around his thumb and wasted no time positioning himself and pushing into her dank cavity. Not surprisingly, her sphincter had gotten well used as it was soft and pliant to the touch. There was no telling what she'd previously shoved inside her, nor how frequently, but it was evident she'd done her share of experimentation.

Lincoln simultaneously pushed and twisted his hand before pulling back and repeating his actions, gradually expanding her tender, forgiving asshole. One inch, then two, getting tighter after three, Lincoln couldn't quite get his knuckles past her rim. But that wasn't about to stop him. Before the night ended, he intended to fully satisfy his sister to secure her admission into his harem.

Returning to Luan's dripping cunny, he added another layer of slickness before reinserting his hand as fully as possible. Then, with one fluid motion, he pulled back and rammed his hand forward with as much force as he could muster. Wrapping her arms under Lincoln's remaining pillow, Luan buried her face in its softness to muffle her cries, biting down to take the edge off the massive intrusion.

With every reciprocation of Lincoln's arm, his fist went increasingly further into his sister, eventually forcing past her sigmoid sphincter into her colon. Luan was beyond words as she felt her lover's hand move up and down inside her. The constant expansion and contraction of her bowels and anus sent a mixture of pleasure and pain through her skinny frame, setting her soul on fire.

While Lincoln never got past his elbow, he was confident that he'd be able to manage it another time. For now, pleasuring his sister's most vibrant, most perverse desires was his only goal. That he was enjoying it, too, was a bonus. While he'd jerked off to such videos, he never imagined himself doing it, the fear of getting filthy deterring him. But, as he found out, everything goes out the window in the heat of the moment, and he found himself autonomically nutting all over his sister's crotch near the pinnacle of their sick coupling.

Soon after Lincoln sprayed another load of cum onto his sister's snatch, Luan came. Her entire body stiffened, and her anus contracted, locking her brother's arm in place. Her insides were so tight and hot it made Lincoln shudder as his cocked leaked onto his bed. Finally, when their bodies began to settle, Lincoln pulled his arm out, falling flat on his face beside his sister.

"Holy fuck, Lincoln..." sighed Luan, turning her face to greet her brother so closely they could feel each other's warm, bated breath. "I feel like I've died and gone to heaven."

"Me too," Lincoln returned with a genuine smile, reaching out to brush Luan's sweaty bangs from her face. "But there's more to come."

"I love you," whispered Luan, staring into Lincoln's eyes.

"I love you, too," complimented Lincoln as his breathing slowed.

"There's only one thing I don't understand," Luan admitted, unfolding her legs and letting her hips fall to the bed. "Why'd mom diddle me at the restaurant? Telling me how you felt was enough. Right?" she asked with confusion, her brows slightly furrowed.

"She wants you, too," Lincoln told her, softly brushing his goopy knuckles across her reddened cheek.

"She... mom... what?" whispered Luan, nearly inaudibly.

"Mom wants to have sex with you," clarified Lincoln. "Just like she wanted to have sex with me."

"Y-you and mom..." Luan stammered, leaving her question unfinished.

"Mmhm," hummed Lincoln, never breaking his affectionate smile. "And Lisa, and soon, Lola. Boy, she can hardly wait, too. But..." he paused. "We need your help," he confessed.

"Lincoln, I..." Luan stuttered. "H-help with w-what?"

"We want to start a porn site of our own," he continued. "Lisa's working on an untraceable server and is willing to help with edits, but we need you for production, lighting, and filming. Of course, everyone will get their turn in front of the camera. What do you say?"

"I..." Luan said flatly before her mouth began silently opening and closing.

"You did say you'd do anything if I fisted you," Lincoln implored. "Remember? Besides," he coyly offered, "if you want me to go even deeper, it'll have to be in front of the camera.

Luan's brain had already gotten fried. Yet, she considered his proposition for almost a millisecond before answering.

"Okay," she snapped, grinning with lust and desire, "as long as you keep doing what you just did, I can hardly wait."
