Lust from Space!

"A good way to provide long-running sexual energy."

"My thoughts, exactly."

"Diminishing returns?" her father asked.

"None that I can tell, but on a longer timeline, who knows?"

"Are the girls safe here?" her father switched from scientist mode to father mode.

"I believe so," Maggie said. "I get the feeling the only danger we're in is from each other."

"You think we're going to hurt each other?"

"Oh! No!" her mother said. Lucy could feel the woman's embarrassment at not being precise. "At least I don't think this place would cause us to. I was just speaking on the nature of humanity."

Don grinned wolfishly and kissed his wife on the neck. Lucy was shocked. She could feel the pleasure both of them received at the kiss, as if she were riding shotgun in her parents' minds. "I love it when you get philosophical," he said.

Lucy let her attention slip away from her parents as her mind processed the notion that for a moment she had been in a man's mind. It was strange, and she had sensed a lot of aggressive, violent emotions, but he had tempered most of them with love and forgiveness. Her mind, however, simply didn't have the years of experience that would allow her to temper those emotions, and she took a second to shake them.

Searching, she found her sister. Talk about aggressive emotions! Sara had heard Lucy run headlong into what appeared from the outside to be a small, roughly circular pool, no more than a few meters in diameter, but surprisingly deep. Standing at its edge, she was waiting for the girl to make a move. Lucy knew that whatever her sister had in mind, it was going to hurt. It also, she could feel, made the older girl's pussy wet.

Lucy allowed herself to detach from the ship, and immediately felt her lungs burn. She moved her body like Sara had shown her and gracefully swam to the surface, where she took a big whooping breath. After a moment getting her breath back, Lucy grinned at her sister. "Seems like I'm safe in here," she nodded at the switch. "That'd be like throwing a hairdryer into a bathtub, don't you think?" Without a word, Sara dipped one toe into the pool. Nothing happened. She poked the switch into the water. Nothing. "Oh," said Lucy, deflated, and began swimming toward the far side of the pool. Sara dove in after her, and Lucy expected to be grabbed instantly, but after a few seconds, when Sara hadn't resurfaced, she stopped and turned around. There, just out of arm's reach and about a half a meter underwater, Sara had stopped cold. Lucy knew what she must be experiencing, but there was something else, as well. With both of them in the pool at once, she could practically hear her sister's thoughts in her head. I wonder, she thought, and dropped below the surface again.

Hi. Sara's consciousness sounded in her head.

Hi. Lucy responded.

I thought I felt you in there earlier, Sara spoke to her telepathically. Just out of the corner of my eye.

Lucy probed her sister's mind. It felt a lot like swimming, actually. But unlike in real water, this was Lucy's territory. So many doors just left unlocked. Lucy helped herself to a memory.

Candles flickered on a birthday cake with the number "8" inscribed on it. Lucy saw herself, standing next to the kitchen table, her friends around her. For someone so young, she looked very confident-much more mature than her peers.

"Well?" she heard herself ask. The little blonde girl had her hands on her hips, expectantly. Lucy was beginning to remember this, herself.

"Well, what?" she heard Sara ask.

"Where's your present?"

"My-Oh! A present!" she heard Sara feign forgetfulness. "I didn't know I was supposed to get you one." All the other kids "ooh"ed and gasped. They knew what could come of not following through on Lucy's expectations.

"It's ok," Lucy heard herself say, genuinely. "All I want for my birthday is you!" Lucy felt the hug she'd given her sister that day, and through this stolen memory, she felt her sister's pussy tingle. All the other kids cooed, "Awww!" at the cuteness, but the longer the hug went on, the less comfortable Sara became, until she separated herself from the young girl.

"I did get you a present, actually," Sara said.

"Oh, goodie!" Lucy saw herself clap her hands and jump up and down. Deep down, she knew that if all she'd gotten that day was her sister, especially in the way that had made Sara so uncomfortable, she would have been content.

It turned out that Sara had gotten her a very nice dress. The family had planned on going out to a play and then a fancy dinner that night as an extended celebration, and Sara had told her she wanted her to look nice. What she hadn't mentioned was that the dress was open-back. Their parents had argued with her about it at first, saying it wasn't exactly appropriate for a young girl, but Sara had managed to convince them to ok the dress if it could be altered to have a loose ribbon lace-up that would keep the dress "closed." It had cost Sara most of her savings to have that dress made. That night, Sara took it upon herself to help Lucy lace up the back, and then took every opportunity to put her arm around her, making contact with the skin on her back. Partway through the night, their parent's wanted a picture of their daughters. What Lucy hadn't known was that, in that photo, the one that this very minute sat on their mantle at home, Sara had slipped her fingers between the ribbon laces and her skin. It was a small gesture, but Lucy knew: this is where Sara had reached the point of no return; from this day forward, her love for her little sister had changed.

Hey! Sara snapped at her telepathically. That's private!

Not anymore! Lucy teased.

Why you-! Sara's eyes popped open and she surfaced, brandishing the electric-blue switch. Lucy surfaced, too, and sprinted as best she could toward the edge of the pool. With just enough distance, Lucy managed to scramble out of the pool, cleared the leafy curtain that surrounded it and ran about five paces before stopping dead in her tracks. Another golden tree? She had a split second for it to register before Sara came bursting through the leafy curtain, and ran headlong into her, toppling them both into the soft, glowing grass under the tree's canopy.

"Oof!" they said, more or less collectively, as they fell into a heap.

Sara's head rang, and for a moment, the desire to punish her sister was not forefront in her mind. "What the heck?"

"Yeah," Lucy said, recovering. "What the heck. Look where you're going!" Sara whipped the switch sharply and struck the bottoms of her sister's feet. "Aiie!" the girl yelped. Sara pointed with the switch. "Yeah, yeah, the tree. I guess there isn't only one."

"What do you suppose is the difference?" Sara asked, staring up into the canopy.

"This one's bigger," Lucy stated the obvious. Sara gave her a look. "And there's more stuff around it. Look." Indeed, around this golden tree was a rose patch, like near the other one, but this one had giant roots that were flat or slightly concave on top and could clearly be used as benches, or even beds. There even appeared to be some kind of orange, glowing mushrooms sprouting here and there. And then, of course, there was the pool.

Sara looked back toward the pool just in time to see their parents emerge, dry from the leafy curtain. "You all done?" Don called.

"Done?" Sara asked.

"Has she had enough, yet?" her father asked.

"I don't think they even started," Maggie said.

Sara looked at the switch in her hand. "Oh, yeah."

"Oh, come on!" Lucy complained.

"Sara, honey," her father said, looming over her. "If you tell someone you're going to do something, you should have the conviction to go through with it, otherwise no one will believe you the next time."

"Yeah," Lucy said sarcastically. "It's the girl who cried, 'I'm gonna whip your ass.'"

"Exactly," Maggie said. "I bet if you hold still, it'll be over before you know it."

"Fine," Lucy said, rolling her eyes and getting on her hands and knees. "I'll play along."

Don saw his eldest daughter hesitate, kneeling behind and to the side. "It's ok, sweetie," he said. "It's just a little harmless fun. Just make her hurt as much as she hurt you and no more. That should be enough."

Sara whipped the switch firmly across her sister's ass, causing a pink line to appear. "Eek!" Lucy yelped. "That hurt!"

"That's for the butt grab," Sara said. "This one's for talking to me like I'm an idiot." She whipped the girl a bit harder.

"Ow! Sara!"

"This one's for invading my privacy!" Lucy tried to scoot away, but Sara grabbed her hair and hit her even harder, and a long red welt raised on the girl's ass.

"OW!! I'm sorry!"

"You were never supposed to know that!" Sara hit her again.

"OWWIE!!"

"Ok, Sara," her father said. "You can stop now. I think that's enough."

"And this," Sara said, not hearing him, "is for telling me you wanted me!" When she hit Lucy, the girl let out an unearthly scream. A deep red welt raised on the girl's ass, and a few beads of blood welled forth. Sara wound up for another strike, but a root suddenly shot up from the turf and wound around her wrist so tightly that she dropped the switch. The root retracted and bound her wrist to the ground, and she fell forward, face first into the grass. Another root bound her other wrist, and others held her knees in place. In no time, she was pinned, the side of her face in the grass and butt in the air.

"Excuse me!" her mother interrupted. "When your father says stop, you stop. Same rules as with me."

From her position, she could only see Lucy, face puffy and red, tears streaming from her eyes. "Sorry," she said.

"Uh, hon," Don started. "Did you do that?"

"Yes, darling," she said. "So can you. See that vine up there?"

"Uh huh."

"Just ask it to move."

"Ok," he said, and then to the vine: "Move."

"You don't need to ask-ask it," she said. "Just think it."

Don took a moment and stared at the vine. "Nothing doing."

"You have to have a bigger picture in your head, I think," Maggie said. "What do you want it to do, other than move?"

Don thought about the vine that was fucking Lucy earlier, but stared at his eldest daughter, bound ass-up in the grass. Suddenly, a vine dropped from the canopy, and slithered onto Sara's back. It wound its way toward her exposed pussy.

"Wait," Maggie said. "You just watched her whip her sister bloody, and now she gets to get fucked? Not until I get some!"

"Water..." Lucy groaned between sniffling sobs, still on her hands and knees.

"What's that, sweetheart?" Maggie asked.

"The pool..." she sniffled again. "The water can heal cuts," she said.

Maggie looked at Don, who turned around and headed toward the pool.

"Now for you," Maggie said, picking up the switch and tapping it lightly on her eldest daughter's ass. "I thought you loved your sister."

"I do," said Sara. A flash of pain and the crack of the switch-Sara couldn't tell which came first. "Ow!!"

"You do?"

"I do!" Another flash of pain cutting across her ass cheeks. "I do!! I DO!!"

"So why would you hit her so hard? She's younger than you!"

"She stole my memory!" The next whip from the switch blinded her with pain. "AAAAIIEEE!"

"You're not making any sense," her mother said. "Try harder."

"We were in-" But before she could explain, Don returned with water cupped in his hands.

"Here you go, sweetie," he said, allowing it to drip and dribble all over her red butt cheeks. Instantly, the welts and blood went away and the girl made the unmistakable sounds of relief. Moving on, he dribbled the rest onto Sara's ass, and the older girl sighed. Lucy was about to move, when the vine the had been wound around her sister, unwound itself and made its way to her. After the intense whipping, Lucy looked forward to having a vine fuck her. "Now for the main course," he said, turning to Maggie and grabbing her around the waist. Don pulled his wife to him and kissed her as hard as he had when they were teenagers. His wife's breasts pressed against his chest, and he ran his hands over her hips, down her ass and squeezed. She moaned into his kiss, and ran a hand down to his hard cock. Kissing him, she moved from his mouth to his neck, from his neck to his chest, from his chest to his mostly flat belly, and then ran her tongue from the base of his cock to the head. He moaned as she licked his cock, and then sighed in pleasure as he felt her hot mouth take him in, tongue teasing all the way.

Suddenly, she pulled her mouth off. "Fuck it," she said in a horse whisper. "I need you inside me."

"I couldn't agree more," he said. "Let's show these girls how it's done."

Maggie took her husband's hand and guided him to a spot in front of the girls. Sara was still bound to the spot, and Lucy might have moved, except that a vine had begun rubbing itself against her pussy, and now she felt a serious urge to get fucked while watching her mother get some long overdue attention. Sara felt the roots' grasp on her wrists loosen a bit, and though still bound, she was able to right herself a bit and watch as her mother laid down on her side and her father slid in beside her. Sara looked over at her sister and watched her face as the vine teased her tight little pussy. Looking back at her parents, laying on their sides in the grass, Sara watched hungrily as Don's cock pressed on Maggie's entrance, but stopped.

"I have an idea," he said.

"It better be good," Maggie said, frustrated. But after he whispered in her ear, a broad smile lit up her face. "Let's do it," she said.

Sara felt a vine drop onto her back, wind its way underneath her, and slither up against her clit right as she saw her father's cock rub up against her mother's clit. "Mmm," she heard next to her, and looked over again. From the look on Lucy's face, her vine had done the same thing. Again, her mother ground her pussy against the length of Don's thick cock. The vine between Sara's legs ground against her clit again, and she found herself moaning, "Are you... doing what... I... think you're doing?"

"That's right's baby," Maggie said. "You're going to feel everything I feel."

With that, Don pushed his cock against his wife's pussy again, and Sara felt the thick vine pressing into her. When his cock slid into Maggie, the woman and her three daughters moaned in unison. "Oh, thank god!" their mother cried.

"Oh, fuck," Lucy said.

Sara just sighed as she felt the vine filling her up. Unlike with his daughters, Don didn't start out slow with his wife. His second thrust was deep and hard, and Sara felt the thick vine slam into her. "Ah!" Next to her, Lucy squealed, clearly not ready for the sudden pounding. Before the younger girl could recover, the vine slammed into her tight pussy again.

"OHH!" Lucy cried, as Don began to steadily fuck his wife. "OOH! Fuck!"

"Ah, fuck I missed your cock!" Maggie moaned. Don held his wife's breast, and tendrils sprouted from the girls' vines and wound round the girls' breasts. When he gently squeezed, he heard three female moans. He fucked maggie harder, and the moans became cries of ecstasy.

Sara watched her father's cock slam in and out of her mother's pussy, and she felt the tension building to a crescendo. As she came, her body shook and she felt a warm heat behind her eyes. She began to recover from the orgasm, but the vine still pumped in and out of her. "Oh fuck!" she moaned, barely intelligibly. She felt something soft rest on her shoulder, and saw Lucy's head resting there, bobbing slightly as the vine fucked her. Sara leaned in as best she could and whispered in the girl's ear, "I love you-oh... fuck-oh, Lucky Lucy! Kiss me!"

The blonde girl raised her head and Sara saw the glowing lights of the forest reflected in her beautiful eyes. Sara tilted her head and kissed her sister hard. "Mmmmm!" the younger girl moaned as she came. Their tongues danced as their bodies shook with orgasm.

"Oh, look at that!" Maggie moaned, watching her girls kiss. "Oh, it just makes me want to-oh fuck! I'm coming!" Maggie spasmed a few times, and then her body relaxed. "Oh, fuck, baby! That's what I needed!" Don pulled his cock, still rock hard, out of his wife's pussy. The girls sighed as the vines popped from theirs, but still on their hands and knees, they continued to kiss. "Do you think the girls are ready?"

"Only one way to find out," he said. Sara and Lucy had been in their own little world, but when Don pressed his cock against his wife's asshole, the vines followed suit, and Sara saw Lucy's eyes shoot wide open.

"Mommy?" Lucy asked desperately as she felt the vine pressing harder on her tight little asshole.

"Just relax, baby," Maggie said. "It's ok." And then to Don, "Go easy... nice and slow."

"Nnngh!!" Lucy grunted, lowering her head. "It's too big!"

"Hey," Sara whispered to her sister, feeling the vine pressing against her own asshole. It was slick, and she knew it would slip into her soon. "Hey, look at me." Lucy raised her head again and looked into her sister's deep green eyes. "Don't tense up, ok?" The girl nodded, biting her lip. "Just let it in."

The head of Don's cock popped into Maggie's ass, and Sara felt the first inch or so of the thick vine slip into her. It felt huge, but now that it was in her, she felt her ass relaxing and stretching to accommodate it. "Gah!" Lucy grunted as her own vine slipped into her ass. Don pushed a bit farther into their mother, and the vines slid deeper into his daughters. "Oh god! Fuck!" Lucy groaned, mouth agape. The younger girl had expected pain, but she was unprepared for how stuffed she would feel.

Don slid the last inch of his cock into Maggie, who made a guttural sound and rolled her eyes back in her head. "How's it feel, girls," Don asked.

"Ungh," Lucy grunted. "I feel like I'm gonna pop!"

"How about you, Sara?" he asked, but his eldest daughter had an odd look on her face. "Sara?" Sara could barely hear him, though. She didn't even notice that the roots had unbound her. It felt incredible. "It's... amazing..." she managed.

Don pulled back until just the head of his cock was inside his wife. "Oh, god!" Lucy groaned. Her tight little ass was getting used to the feel of the vine that impaled it. She looked at her sister, who appeared to be in a state of bliss.

"Ok, baby," Maggie said huskily. "Fuck my ass!"

Don thrust his cock back into his wife, but her moans were drowned out by Lucy's scream. "AAA-EEE!!" The girl buried her head in the grass and whimpered as the vine reamed her asshole. "Ah!"

"Maybe we should take it easier on her," Don said, pulling back again.

"NO!" Sara shocked them all. Her face was a tangle of crazy emotion. "Fuck us! Fuck us!" she demanded.

Don was happy to comply and thrust his cock back into his wife. Maggie reached back and up and forced her husband's mouth onto her own as their eldest daughter made beastly, lustful sounds, and their youngest daughter squealed. Steadily, he began to pump in and out. "Mmmm," Maggie moaned into his mouth.

"Ohhh, fuck yeah," Sara sighed, her voice rasping. Lucy went silent, her face contorted in an ever-changing mixture of pain and pleasure. The ass fucking was beginning to wear on the blonde girl, and she reached back under her and began to rub her clit to add pleasure to the pain. When Don saw this, he reached down and started rubbing Maggie's clit, causing all three of his ladies to moan. And that was it: he felt a tightness in his balls, and gave his wife's ass three hard thrusts before shooting a hot jet of cum deep into her bowels. Her ass was tight and milked every last drop of his cum out of him. When his cock slipped out of her, he heard three gasps of relief. Lucy toppled sideways into the grass, exhausted, and Sara slowly crawled over to her and took the girl in her arms. "You ok, Lucky?" she whispered, stroking her sister's hair.
