Lust from Space!

Sara looked at her younger sister with eyes of shame and fear before managing, "I don't feel it anymore."

"Don't feel... what?" Lucy asked, hesitating. "Me?"

Sara's red, tear-streaked eyes went wide. "No!" she whispered hoarsely. "Oh, no no no." Sara dipped one arm under the water, snaked it around her sister's waist and pulled her closer, but it felt strange. Good, but strange. She noticed a distinct look of relief in Lucy's crooked smile. She dipped her head under the water for a moment to wash off the tears. When she resurfaced, she turned and faced her parents. "I'm not feeling the..." she paused, looking for the term "... well, the whatever it was that helped us-that encouraged us to..." she trailed off, frustrated that she couldn't even bring herself to say it.

"Huh?" her father asked.

"I think," Maggie said, "she's no longer feeling the effect of the pollens and nectars that seem to heighten our sexual desires."

"Yeah," Sara said, guiltily, avoiding eye contact. "And I dragged you all into this. I mean, I made you commit incest!"

"Hey! Sweetie," her father said, watching his daughter's expression of regret and shame. "You didn't make me do anything. I'm an adult, and I can take responsibility for my actions."

"You didn't make me, either," her mother said. "Though it kind of seemed like it at the beginning, I stand by my choices."

"You did kind of make me, though," Lucy said with a grin, poking Sara in the ribs. But she saw Sara's seriousness. "Seriously, though. How long do you think it'd have been before one of us caught the other spying in the shower?"

"You were spying on me in the shower?" Sara asked.

"And you never snuck a peek at me?" Lucy said with a devilish grin.

"Well..." Sara said, smiling a little again.

"See?" Lucy said, pulling in for a closer embrace. "It was only a matter of time before this," she indicated their closeness, "turned into this." Lucy quickly moved in for a kiss, but without the enhanced erotic drive, Sara felt awkward about it. Lucy kept at it, moved up and nibbled at her sister's ears, and when their lips met again, Sara returned the kiss. She smiled broadly and looked contentedly into her sister's eyes.

"This," she said and kissed Lucy again, letting her tongue dance against her sister's. "This is the real thing. This is how it should feel." And it was, but it also felt wholly new, as if the past week had been something from a dream.

Suddenly, the girls noticed an aqua glow on their faces, but it wasn't from their faces. They looked down, and saw that the water around Sara glowed brightly. Lucy floated away a bit, just to get a look. "No kidding!" Lucy said. "Can I come back? Is it safe?"

Sara poked at the glowing water. It felt the same as it had before. "If you don't, I'll have to chase you down again," she said, and Lucy drifted back.

"I wonder why I can still feel it," Maggie wondered out loud.

"Me too," Lucy said.

"What," Sara teased Lucy. "Still hot for sister?"

"You bet your ass!" Lucy said and kissed her, slipping a hand down around Sara's hips and squeezing her butt.

"Perhaps," their mother said, ignoring her daughters' flirtations, "you gained some sort of immunity or tolerance from the link."

"It's possible," said Don. "Interfacing with the plants themselves could be an antidote after multiple uses. Still, it begs the question: we've all spent the same amount of time in the link, so why wouldn't we be tolerant, too?"

"I did notice one thing," Sara said. "Did you notice that Lucy was much more susceptible to the vapors, but that it took you a much larger dose—like drinking the water—to become locked in?"

"Hey!" Lucy complained. "Are you saying I'm weak?"

"The opposite, actually," Sara said, and then addressed her parents again. "When we left, when it had just been me and Lucy, she was the first to shake the feelings. But once you guys drank, the effects were more or less permanent, as far as I can tell."

"Permanent?" Don sounded frightened.

"I doubt that," Maggie said. "But I get the theory, and I think it holds water. We were harder to seduce, so it took more work. It may just take more contact with the link to build up a tolerance."

"Whoa!" Lucy warned. "Slow down a sec. First of all, shouldn't I have been the first to be tolerant?"

"You were, silly!" Sara kissed her on the cheek.

"No!" Lucy retorted. "I'm still horny. All I can think about is your sexy body and how much I want the four of us fucking again."

"That sounds good," said Don, dreamily.

Sara took water from the pool and held it in the palm of her hand. "Drink," she said.

"But—" Lucy started.

"Drink!" Sara put her hand up to her sister's mouth, and the girl drank.

"What the-?"

"Nothing, right?" Sara asked. Lucy looked like she'd seen a ghost.

"Nothing."

Sara giggled and teased her sister's breast, "You're just a horn-dog, babe." Don burst out laughing, and even Maggie couldn't help but laugh.

"Ladies," their mother said, and then when she had their attention, "get to the point."

"Yeah," Lucy demanded. "Get to the point!" Sara grinned and dunked the girl, who shrieked and came back up sputtering. Don chuckled.

"My point was that there nothing new in our memories that we haven't shared with the ship."

"So then we really do need to add—" Don started, but Sara stopped him.

"I don't think so. The ship's big enough to hold my entire Wilderness Girl troop, and while the idea of bringing them here is enticing, I'm not sure it's necessary." She turned to her father. "Remember when you were teaching a little car repair? I think the sexual energy we've been emitting wasn't enough to restart the ship completely, but it may have triggered a subsystem designed to trigger sexual memories and use that energy to jumpstart the main systems."

"That's a hell of a theory," her mother said, beaming.

"A hell of a good one," her father added. "I didn't think you were even paying attention."

"Pfff... nerd," Lucy said. "You sound like we're on Star Trek."

"Babe," Sara said. "We're on a living spaceship that's evolved to run on sexual energy."

"What's your point?" Lucy said fatuously, staring lasers into Sara's eyes.

"Anyway..." Maggie said, prompting her daughters to return to the conversation.

"Anyway," Sara continued, "I think the ship's running. Now we just have to find out where to go to fly the damn thing."

"I think I can help with that," Lucy chimed in. "I found a door."

Lucy led her family to the place where they'd had their first orgy. Don noticed first, and asked if she'd been bound for a reason when he'd first found her. The girl nodded an affirmative, and soon enough, brought them all to the door. For a moment, the stood there, appreciating the moment. They'd all passed a point of no return with each other long ago, but here, in the banal form of a wooden door, stood the final one.

Sara saw her sister's hesitance in reaching for the doorknob, and knew that the last time Lucy touched it there had been violence. She covered her sister's hand with her own, and together they gripped the knob. Nothing disturbed the peace except a current of air rustling the leaves round them. With a squeaking twist and click, the girls opened the door.

The light from the room beyond blinded them briefly, and they held up their hands to shield their eyes. When their eyes adjusted, they found that the room was large, crisp and white, all smooth surfaces and right angles. Nothing adorned the walls, and there was nothing that could be understood as a computer. As far as they could tell, it was a pure, white box. The center of the room held the only anomaly, a slab as white as everything else, save the top, which was black as obsidian, but reflected no light and seemed to have depth. Drawn to it, Sara entered and approached. Her father started to say something, but stopped. If there was danger in the room, it was beyond his understanding. Lucy was next to enter, followed my Maggie, and finally Don followed them in, closing the door behind him.

As they approached the slab, they noticed that despite the bright light, the smooth white floor and the air in the room was cold—almost painfully so. Still, they pressed on.

"What is it?" Lucy asked as they stared in to the infinite blackness that topped the slab in the center of the room. The top of the cube itself was two meters square. Without a word, Sara slowly reached out and touched the surface. The moment her fingertips touched the surface, she gasped and Don reached for her, but she waved him off.

"Look," she said, keeping her fingertips on the slab. Down the side of the slab, the same blackness began to creep toward the floor—like roots and vines. She pressed her whole palm against the surface, and took in a sharp breath, feeling a surge of lust almost turn her knees to jelly. When she regained a bit of sense, she noticed that more of the blackness had begun creeping down the sides of the slab.

"That's..." Don said. "That's not quite like anything I've ever seen."

More blackness spilled toward the floor when Sara put her other hand upon the slab. This time, she did stagger a bit, and her mother kept her upright. "What is it?" Maggie asked, an uncomfortable feeling rising in her akin to that of a rat in a trap. "What's it doing to you?"

"I... uh..." Lucy breathed. "I think I can answer that." The girl had reached out curiously to see if the blackness had any texture to it. It did not, but it held something else. "I think we've found the source."

"Source?" their mother asked. Lucy grabbed her mother's wrist and put her hand upon the slab. Instantly, the woman understood. This was the purest form of whatever the pollens and nectars held. Instantly, the room no longer seemed cold, and a surge of hot lust coursed through her. "Oh, my god." The woman's eyes went to her eldest daughter as the girl leaned heavily on the slab, panting, her thighs squeezing together rhythmically. Clearly, Sara needed release, but couldn't bring herself to take her hands from the black surface. Maggie, ran her hand lightly down the girl's back. "Oh, baby," she said, "you need some loving don't you." Sara turned her face to her, and the pleading expression would have nearly broken her heart had she not been laughing so hard.

"Please, mom," Sara said, nearly oblivious to the fact that her mother was laughing. "I need it so bad."

Lucy, aware of the tidal wave of lust her sister was struggling with, moved to her sister and kissed her. Pulling away and looking into her sister's eyes, she could see that her sister was struggling to stay afloat. Knowing her, she was probably trying to maintain control—to be the responsible one in this unknown place. When Sara and the tree had taken her virginity, Sara had known the place and what it would do. She knew there had been no physical danger. Here, thought, Lucy had a leg up. Somehow, she knew that this particular place, what all was said and done, would be hers. But the big-sister instinct was still going strong, and tears began to roll down Sara's cheek as she fought her own enhanced lust. Caressing the older girl's cheek, Lucy said, "It's ok, Sara. Just let go."

"But—"

Lucy put a finger over her sister's lips. "You trust me?" Sara, tears still in her eyes, nodded. "Then let go." With that, almost instantly, a smile, mischievous and predatory bent the older girl's lips.

Sara felt her last bit of self-control fall to the invading lust, and she tore her hands away from the black surface, grabbing her sister's face and kissing her sloppily. Lucy deftly separated herself from her sister and slammed her toward the slab, but Sara caught herself with her hands, but slipped. When Sara's forearms touched the slab, she froze and let out a whimper. "Oh shit!" she groaned in frustration.

"Well?" Lucy said, turning toward her father. "What are you waiting for?"

Don eyed his eldest daughter, bent over the slab at a right angle and offering herself to him. Her pussy was visibly wet and his cock was rock hard almost instantly. He took a step forward and caressed Sara's butt, causing her to moan softly.

"Do it, Don," Maggie said, already sliding a finger across her own clit. "Fuck her!"

Don held his breath and pressed his cock against his daughter's wet opening and felt as it slid in, the girl's tight warmth enveloping it inch by inch. When he was fully in her and her ass cheeks pressed firmly against his loins, he let out his breath. He couldn't believe he was fucking his beautiful daughter again. She had taken after him in so many things and made him so proud of her accomplishments that, after the initial shock of incest had faded from their first encounter, he was actually honored that she would choose to include him in this sexual adventure.

"Oh, fuck..." Sara groaned as Don's cock filled her up. He grabbed her ass and began to slide in and out of her. "Oh, daddy! Fuck me!" Obligingly, he began to pump into her harder, causing her firm young ass to slap against him with every thrust. Sara squealed in delight and pressed back against him. All the while, blackness oozed down the sides of the slab toward the floor.

Maggie swiped her finger across one of the black veins, but it had no texture. It was part of the slab. "This room's gonna turn black," Lucy said, answering her mother's unspoken question. "Eventually." Don and Sara's fucking had caused the blackness to spread faster, but not by much. There just wasn't that much skin contact.

"Well, time waits for no one!" Maggie said gleefully, and without warning, scooped Lucy up and sat her on top of the slab. Black poured down the sides and onto the floor as if she had thrown the girl into a full bathtub. The floor where Maggie stood flowed with black, and the woman felt her knees buckle as she dropped to the floor, chest heaving with lust. Now with feet and knees in contact, the black spread more, under Sara's feet and then under her father's. After a short chain reaction, half the floor was black. And it was still spreading.

Sara shrieked as her father, now in contact with the black, began to ravage her young pussy. "Ah God!" The girl gritted her teeth as Don pounded into her, causing ripples of pleasure. She'd honestly thought she'd only get the rough fucking she liked so much from the trees, but her father was more than capable, it seemed. "Oh, daddy! Fuck me harder!"

Maggie realized that Sara was in no danger and turned back to her younger daughter. The girl sat on the edge of the slab, eyes glazed and staring off into the distance. Maggie tried to rise, but her knees turned to jelly again. She shook her daughter's knees, but got no response. She thought about using the slab to brace herself in order to stand, but knew that as soon as her hands touched the black, she'd be right back on the floor. Maggie slid her hands up her daughter's thighs toward her hips in an attempt to use the girl as leverage to stand, but the girl gasped lightly but audibly, her eyes still glazed. Her daughter's legs parted slightly, and Maggie's hands slipped off the girl's hips and slapped down onto the top of the slab, sending blackness farther toward the walls. Her head swam with lust, and between her young daughter's legs, she saw dewy moistness. Lucy appeared to be in shock from the sensory overload, but wherever the girl's mind had gone, it was making her incredibly wet.

Maggie had to taste her daughter's pussy again, and without hesitation she parted the girl's legs and licked lightly at the slit. Lucy gasped a little louder this time, but still remained motionless. Maggie planted her lips on the girl's pussy and kissed it as if it were the last time. She couldn't get enough of the young girl's sweet, tangy wetness, and the more she tasted, the more she needed.

Lucy had been lost in an erotic paradise she had never known could exist. Barely aware of her mother's touch, she felt an entire universe of sexual knowledge filling her brain, but it was too much, like drinking from a fire hose. As her mother began eating her pussy, she felt her mind pulling back from the flood as if reaching the end of a bungee cord. When the woman's experienced lips sucked on her swollen little clit, Lucy snapped back to reality. A fiery heat radiated from her pussy, and out of desperate instinct, she grabbed her mother's head and pressed it harder against her. "Oh mommy!" she cried out.

Don had fought for control when the blackness washed under his feet. The base, predatory lust that had struck him like a hammer when he'd first come down into the ship had returned, but he was prepared for it this time. He looked at his daughter, writhing in the throes of ecstasy. Some beastly part of him wanted to punish her for being such a wanton whore that she'd fuck anything, even her own father, but he retained enough control over himself that he knew better. They'd been chosen for this long before they'd come to the valley. The Agency had sent them, but this thing, this ship, or whatever it was has seen to it that it had been them specifically. Don was certain that the influence of this thing had spread far past these seemingly solid walls. It had sensed their buried attraction and sexual insatiability, and had craftily combined it with their familial love until they had ended up where they were now.

He looked up and saw his wife push their younger daughter back on the slab. Blackness surged out again, this time reaching the walls. As the blackness expanded, the light had dimmed. Soon, the entire room would be pitch dark. His wife was as sexy as ever, and when she climbed up on the slab and dove between Lucy's legs, he began slamming into Sara with reckless abandon.

"Oh, daddy! I'M COMING!" Sara screamed. Every muscle her young body could spare clamped around his cock, and she shook as she came again and again. The feeling of her fathers cock filling her up, hot and hard, sent shock waves through her until she could no longer take it. Less gracefully than she would have liked, she collapsed to the floor.

Don saw Sara fall, but it took a second to register in his brain. The clouds of frustration cleared and he knelt next to her. "Sara! Are you ok?"

Sara, sprawled belly up, reached a hand up and cupped the back of his head in it, pulling his mouth toward hers. She kissed him and smiled. "I love you, daddy."

"I love you too," he said, meaning it. He felt something brush against his cock, sending shivers of ecstasy through his body, and looked down to see his daughter's fingers lazily caressing his cock.

"You want me to finish you?" she asked.

"God, baby," he groaned. "More than anything." That was also the truth. But for the moment he was able to overcome his lust. "But what do you need?"

"Need?" Sara asked, as if no one had ever asked what she'd needed before. There was a long silence, and they looked at each other in a way they knew no father and daughter had ever experienced before. The silence, however, was broken.

"Aww..." Lucy cooed with fake pity, her face peeking over the edge of the slab. The blackness had now climbed halfway up the walls, and the girl's face was more or less a silhouette against the still-white ceiling. "Are you all tuckered out?"

"Careful," Don warned. "I'll fuck you until you can't stand." And he meant it.

Maggie's face peeked over the slab, too. "Don't make promises you can't keep," she said.

"Oh, mom," Sara said, rolling her eyes. "Get down here, the both of you!" she scolded.

Lucy in her youthful exuberance and flooded with lust was off the slab and by her sister's side in a flash. Maggie, still flooded with desire, but tempered by experience and dignity, rolled off of the slab and joined her husband.

"Anything you want, lover girl!" Lucy said, kissing Sara's neck.

And that's when it hit her: her orgasm had made her immune to the effects of the blackness. A kiss from her sister felt great, but for the moment, she was satisfied. It wouldn't last, of course—not in this place—but it gave her a moment of clarity. "Anything?" she asked. Lucy nodded eagerly. "Well, dad didn't come, so..."
