This story contains graphic descriptions of lesbian sex acts between siblings. The contents of the story are entirely fictitious, and I do not condone these actions in any way, shape, or form. Now on to the story. Chapter 4: Moving Fast Samantha stretched luxuriously in bed, arching her back and thrusting her large, firm breasts upwards. She let herself lie flat again and opened her eyes, looking at the rays of sunlight falling across her tight, tanned body lying naked on the bed. Her sister, as usual, had awoken earlier. Samantha smiled as she sat up on the edge of the bed and yawned, again stretching. She stood up and walked to the door, taking just a moment to check the time. It was a little before ten. When she got downstairs, breakfast was waiting for her, as was Kari. "You've finished your breakfast already," Samantha said, noting that Kari's plate was already empty. Kari nodded and smiled seductively. "But now I've got something else to eat," she said. Samantha giggled and sat down at the table. Kari crawled on her hands and knees to get under the table. "Spread your legs and scoot in," she said. Samantha did as Kari ordered and began to eat. She gasped involuntarily as she felt her sister's tongue run the length of her cunt and flick her clit. As she ate, she began to leak more and more, and shudder more and more, gasping and moaning between, and sometimes during every bite. Finally, she felt the heat in her lower stomach building up, and she knew she was past the point of no return. She stretched her legs out and clamped Kari's head between her strong thighs, and exploded, letting out a loud scream of ecstasy. Her beautiful ass, slicked slightly with the perspiration that had built up slipped off the chair, and she slid to the ground, next to her sister. The cum soaked face and shoulders and the blonde hair plastered to it had become a common-place enough picture in Samantha's mind that she hardly noticed it. She leaned in and began to lick Kari's giant breasts, first one and then the other, alternating rapidly before settling on the right breast and suckling the beautiful nipple into her mouth. Kari fell back, moaning, and Samantha went right with her, keeping the nipple in her mouth, gently nibbling it between her teeth. She reached down with her free hand, and felt Kari's pussy. It was sopping wet and dripping. She slipped three fingers in with ease, and added a fourth without too much difficulty, pumping them in and out of Kari's dripping cunt. She switched her focus to Kari's left breast, and formed the duckbill with her formerly unoccupied hand. But she was at a bad angle, and finally she had to let Kari's breasts go. She slithered down Kari's body, tonguing her abs, and leaving a trail of pussy juice on the older sister's toned leg before she sat up, the very top of her head brushing against the table. Again she formed a duck-bill shape with her hand, and then pushed hard on Kari's opening. --------------- Kari's eyes opened wide and she groaned as she felt her cunt lips stretch to accommodate Sam's hand. She was easily able to feel it as the last bit of the hand popped in, and Sam was buried up to the wrist in her pussy. She moaned aloud, reaching down and grasping one of her large, firm breasts, lifting it to her mouth to suckle on it while Sam explored the depths of her pussy. She could feel the fingers moving around, poking her in places she could never have reached herself. All too soon, she felt herself building towards a shattering orgasm. "Sammm," she groaned, releasing her breast from her mouth, "I'm gonna cum," she gasped out. Sam gave her one last thrust for good measure, then pulled her hand out as Kari screamed, her cum jetting out of her to cover Sam's face and breasts. Kari continued to writhe and spasm long after her lungs had exhausted themselves and her scream had come to an end. Sam planted her mouth directly over Kari's pussy, and took as much juice in as she could, swallowing the salty-sweet liquid as quickly as she could manage. Still it was too much. She slid up Kari's body, releasing a mouthful on her sister's glorious breasts, then lay one her side, one leg draped over Kari's well-defined stomach, and smiled at her sister, who gave a smile in return. Kari leaned in and kissed Sam on the lips, tasting her own cum there, which she licked off with her tongue, too worn out to do much else. "Sam?" she asked when they had been lying like that under the table for at least five minutes. "Why didn't we start this years ago?" Sam sighed contentedly and nuzzled her face into Kari's slightly sticky hair. "I think I would have freaked," she said quietly. "It wasn't until a few months ago that I started thinking about you while I was bringing myself off." Kari nodded, breathing in and out, watching her breasts rise and fall in front of her. "And I didn't really start lusting after you until after your breasts really started to grow, again, a few months ago. When they went from those cute little A cups to these D cups in almost no time." She laughed nervously. "When you started having to buy new bras and swimsuits every two weeks, I noticed." Sam smiled and licked the side of her sister's face. "Yeah. That's slowed down, but I don't think it's stopped. I'm probably gonna end up with the same dimensions as you." She licked her sister's face again, tonguing the ear lightly. Kari turned her head to face her sister, catching the extended tongue in her mouth and gently nibbling on it before letting it go. "You could end up larger," she said. "My breasts weren't as big as yours when I was your age." She forced herself into a sitting position, scooting herself out from under the table. "Come on, let's get showers." Sam scooted herself on her back out from under the table, not bothering to sit up until she was free. "Why bother?" she asked. "We'll just get dirty again. We might as well shower when we're just about ready for bed." Kari didn't respond, recognizing the truth of Sam's statement. "But what do we do now?" Sam mused, almost to herself as she stood. Kari managed to get herself upright on still shaky legs with some help from Sam. Who smacked her ass playfully once she was standing. "Follow me," she said after a moment, leading the way upstairs. Kari followed her, her eyes glued on Sam's shapely legs and ass. "No complaints here," she said, eliciting a giggle from Sam. --------------- When she got to their parents room a few steps ahead of Kari, she found the discarded strap-on, still wet with her own juices. It was a simple matter to pull it on. Kari watched her do so with mild interest and intense lust apparent in her eyes. Samantha turned around showing the ten inches of rubber now attached to her thin frame. "What do you think?" she asked with a thin smile. "Are you ready to get the shit fucked out of you?" Kari's weariness from before seemed to instantly vanish. She didn't say anything, just nodding and stepping towards her sister. Samantha didn't wait for her sister to get in close to her, covering the remaining distance in two steps and shoving the long rubber cock deep inside her sister while she was still standing. Kari gasped in surprise, but the cock had slipped in easily enough. Samantha stood on her tiptoes, getting it all up inside her sister, deeper than even her hand had gone. She kissed Kari passionately on the lips, an open mouth kiss that Kari returned with equal passion. The two swayed around the room in a sort of imitation of a dance, Samantha's strapon still buried deep inside Kari's pussy. They finally stopped when Kari backed into a wall. Samantha gripped her sister's upper arms, and began to do an imitation of the squats. Every time she bent her legs about nine inches of the rubber dildo would slide out of her sister's sopping pussy, and then she would straighten up and slam it right back in. The four inches in her own end were doing a pretty good job of stimulating her cunt, though she could tell that Kari would reach orgasm well before she did. That was fine, she decided as Kari gripped her shoulders and in consequence, some of her dark brown hair. Samantha was relishing the rhythmic feel of her breasts sliding up and down her sister's sweaty body, he nipples hardening, and the brief pressure she felt as they mad contact with Kari's breasts. >From what Samantha could tell, Kari's nipples were just as hard as her own. She felt Kari's body begin to jerk, and heard the moans of her approaching orgasm. She pulled out, and Kari tried to impale herself on the dildo, now moaning in unfulfilled desire. She was hovering on the very edge of a very strong orgasm, and Samantha was denying it to her. She turned Kari around and pressed her against the wall, licking the nape of her neck. "You're an anal virgin?" she asked quietly, continuing to lick her sister's back. Kari nodded and Sam gave a silvery laugh. "Not for much longer," she said, moving the very wet cockhead up and down between Kari's thighs, particularly around her puckered hole. Kari was too far gone to protest, and she couldn't reach her own pussy from the way her hands were trapped against her body. Finding the angle inconvenient, Samantha dragged her sister over to the bed, and forced Kari to her knees, with her upper body on the bed, and her ass protruding out over the side, her legs on the floor. Samantha grasped the firm, tanned globes of Kari's ass and pulled them apart, revealing the small, puckered hole. She placed the cockhead against it and pushed, watching in amazement as the hole expanded to swallow the head of the dildo, and she began to push the shaft in as well. --------------- Kari's ass seemed to explode with pain, and she screamed loudly. Underneath the pain though, she could feel the pleasure, and she knew that it was only transitory. Once her ass had adjusted to the huge dildo, all that would be left was the pleasure. At the moment though, she was in agony. She finally felt Sam's hips touch her own, and Sam's hands began to lightly trace their way down her side. Sam leaned in, her large breasts flattening against Kari's back, and whispered in her ear. "I'll wait. Just tell me when you're ready for it." Sam's hands continued to play with Kari's sides, particularly focusing on her hips and the outer edges of her ass. Meanwhile Sam's tongue traced it's way along Kari's upper back, neck, and face. Finally, Kari felt the pain in her ass begin to subside. After a few minutes, it had disappeared entirely. Finally, she reached back and grasped what she could reach of Sam which turned out to be her right arm. "I'm ready," she said. Sam didn't need any more encouragement. She slid the strapon almost all the way out, and rammed it in deep. Stars exploded in front of Kari's eyes. She couldn't believe the sensations. It was like nothing she'd ever experienced before. She gasped, moaned, her head rolled from side to side. "Fuck me!" she yelled. "Fuck my ass Sam! Fuck it! Harder!" Sam's rhythm increased, and Kari began to hunch her ass back, trying to increase the penetration as much as possible. Sam was sweating. Kari could feel it dripping off of her sister's breasts and onto her back. Kari herself was sweating bullets as well, the smell of sex and sweat mingling in the air. Kari could feel clearly every bump and ridge on the toy as it slammed into her ass. She could feel her orgasm building within her, and within a few moments her cries for Sam to fuck her had descended into simple screams. -------------- When Kari's orgasm began, Samantha cupped both her hands under the tap that was her pussy. As the juices flowed, Sam splashed them over her face and chest, then cupping her hands once more, drank the sweet nectar that was flowing from her sister's spasming body. She pulled out, watching as her sister's ass went from a gaping hole back to the tiny pucker it had been. Then she flopped down onto the bed, exhausted, unsatisfied, her breasts having. Kari rolled over to come to rest next to her, her eyes shining. "That was amazing, Sam," she said lustfully. After a moment, she frowned a little. "But you haven't cummed yet, have you?" Samantha shook her head. Kari smiled. "Well, I should change that," she said. She walked away from the bed, towards the pile of toys on the ground. Samantha watched her tight ass sway as she walked, then watched her as she bent over searching through the toys. Finally she found what she was looking for. A string of anal beads with a furry tail attached to it, and a large vibrator, probably about a foot long, and thicker than the strapon. "Get on your hands and knees," Kari said without preamble, and Samantha obeyed before she really even thought about it. Kari walked over to her and handed her the beads. "Suck on them," she said. "Get them nice and wet." Samantha took the beads and began to suck on them with gusto. Kari spread the cheeks of her ass and began to lick her small hole, lubricating it for penetration. "Okay, give me the beads." Again Samantha just handed her the beads without thinking about it. Kari put them up to her hole and popped them in one at a time, each one causing a mix of pain and pleasure for Samantha, until they were entirely inside her. "Ooh," Kari said. "Stand up and look at yourself in the mirror." Samantha stood up and walked over to the mirror. Her large breasts stood proudly out, topped with her beautiful pink nipples, now hard as diamonds. She followed her eyes down her athletic stomach to her pussy in between two muscular thighs. She turned around, and saw the tail sticking out of her ass, and she could suddenly feel the beads inside her. Kari was looking at her with a large grin on her face, seated on the bed. "Come here," she said. Samantha took a few steps across the room, feeling the beads in her ass stimulating the walls, the tail brushing against the back of her thighs as she went. By the time she reached the bed Kari had stood up, and she pulled Samantha into a tight hug, and the two kissed passionately, their tongues dancing around for a few minutes, groping and feeling each other's bodies. Kari grabbed Samantha's shoulders, spinning her around and pushing her down onto the bed. Kari lay down atop her sister, and held up the huge vibrator, and brushed it across Samantha's face, trailing it from her forehead to her nose, down to run around her lips. Open up, Sam," she said. Samantha opened her mouth as wide as she could and the vibrator slid inside. ------------- Kari watched with amazement as the vibrator slid into Sam's mouth. The thing was over a foot long, and only a few inches fit inside it, her lips were stretched around it and the whole thing seemed like it could barely fit inside. Sam was breathing intently thorough her nose, then without warning she reached up and grabbed her sister's hand and pulled it down, pushing the vibrator further into her mouth and down her throat. She was deep-throating the vibrator! Kari couldn't believe it. Though really, when she thought about it, this was all unbelievable. Her incredibly sexy fifteen-year-old sister was lying naked on their parent's bed, Kari lying on top of her, equally naked, the two of them having had an incredible amount of sex in the past few days. Sam had established a rhythm on the vibrator, and finally, Kari pulled it out. Sam's breasts heaved greatly with her heavy breathing, and Kari wasn't about to give her any respite. With barely any preamble, Kari placed the head of the vibrator against Sam's pussy, and pushed. Sam's cunt lips stretched wide to accommodate the vibrator's immense girth, and then it began to slide inside her, inch by inch, until finally, the entire foot-long length was deep within her. Sam's eyes were rolling, sweat had pooled in every valley on her body, beaded on every bit of her tanned skin, and she was gripping the covers tightly with her fingers and panting. Then Kari switched the vibrator on. Sam froze, absolutely motionless for a few seconds, she didn't even breathe, the only sound the vibrator's muffled buzzing within her. And then she let loose, a scream of pure, primal pleasure. She shook with the power of her orgasm, droplets of sweat flying off of her. Juices flowed out of her pussy around the immense vibrator, and one orgasm flowed into another and another. Finally Kari pulled the vibrator out of her sister's sopping pussy, and the orgasms died away. She sucked and licked the vibrator clean, than looked at her younger sister. She had fallen completely asleep. Kari smiled, setting the vibrator aside, then she moved up to rest against her sister, wrapping her arms around the young girl who had become her passionate lesbian lover. Nothing could come between them. End Chapter 4.... I have run out of ideas for what the sisters can do together with only the two of them. I am planning on introducing a new character in Chapter 5. At the moment, my thoughts are centered on a girl named Kimberly, the younger (how much younger, I am unsure) cousin of Sam and Kari, who will spend a night or two at the house, and discover the sisters' secret. Any ideas or suggestions along this line would be appreciated. As always, characters are the possession of Sam B. and may not be used without her expressed written consent.
