"Taste this tit, Kyle," Karla said, holding it toward him. "It's sweeter than that one."
Kyle's long, auburn hair fell down around his face as he leaned over to take the proffered breast. He licked at the elongated peak his sister had sucked, and then began to pull on it himself.
Having distracted him temporarily, Karla's lips traced down along Marcy's ribs and over her abdomen to the raised mound that had been her goal from the start.
Marcy reached out a hand to each of her lovers. She touched Kyle's strong young buttocks, and stroked them lightly before moving on to his thighs and flat belly. The other hand encountered Karla. The girl had turned around, and her pertly rounded bottom and the backs of her thighs were directly in Marcy's line of vision. In a kneeling position, with her head lower than her up thrust rump, Karla's red-thatched cunt was unguarded and available. Marcy's caressing fingers lovingly stroked the firm half-moons and satiny thighs, and then crept forward to seek the hot, moist flesh of that steaming slit.
"Ummmm, that's groovy," Karla said, wriggling her bottom and opening her legs wider so Marcy's fingers could tangle in the red hair and gain access to the pink lips underneath.
Karla's mouth was as busy as Marcy's fingers, her tongue licking all over Marcy's belly and dipping hotly into the deep navel. "Hey, you'd have made a great belly dancer," she giggled, as Marcy's surface muscles rolled with pleasure.
Having sucked and nibbled at the tender breasts until he had had his fill, Kyle's lips worked their way down to Marcy's flanks, kissing the flaring hips and setting to work on the thigh opposite the one his sister was licking.
Marcy's fingers were deep in Karla's cunt, examining with deep interest the convoluted inner folds, probing at the sleek inner walls and feeling the tightening of the well-trained muscles. How strange it was to have her fingers inside another woman. This was so different from exploring a man. This was the very center of another girl's being, and she was permitted to invade it as she chose.
Meanwhile, Karla's lips were parting the dense foliage that covered Marcy's mound, licking at a few drops of sperm that remained from Kyle's orgasm. She giggled as she savored it. "Oh, Kyle, she tastes of you! This is wild! To taste your own brother's cum in another woman."
"I know something even wilder," Kyle said, moving his mouth closer to his sister's. "Let me have some. I've tasted the cum of a lot of guys, but never my own."
Marcy's fingers eased in and out of Karla while her other hand caressed Kyle's thighs and belly, and then the thick rod that was now revitalized. She began to slide her fingers up and down its length, lightly squeezing his testicles at one end and rubbing her palm in circles over the sensitive tip at the other.
But something far more exciting was happening to her. Karla's tongue had located her clitoris, and was licking it avidly, hardening it into a throbbing miniature of the male organ Marcy was fondling.
Then Kyle's lips were frolicking through the silken blonde hair, and dipping between the opened cunt lips. While his sister nibbled on the engorged clit, his tongue plunged into the fiery fissure below it.
Marcy's head was spinning again. This was the most fantastically exciting thing that had happened to her yet. Imagine having her clit sucked by a girl while that girl's brother stuck his tongue into her cunt and licked his own cum from her depths!
"You ought to taste this, Karla," Kyle said. "There's a mixture of me and her in here that's out of this world."
"I'm in there too, you know," Karla said. "I rubbed pussies with her until she came, so some of my juice is bound to be in there with yours and hers."
"You're right," Kyle said after sampling Marcy's slit again. "I guess that's what makes it so tasty. Three flavors – just like those giant ice cream cones we used to love as kids."
The Karlows giggled together like naughty children, and Karla's mouth left Marcy's clit and moved down the long gash. "Okay, give me some. I still like three-flavored treats."
In her eagerness, Karla straddled Marcy and crouched down until her bottom was touching the other girl's big breasts. As her greedy tongue lapped noisily at Marcy's pink hollow, she slid farther backwards until Marcy found herself looking up at the tuft of carroty pubic hair and the dilated cunt lips underneath. Startled, she simply stared at the open hole, and inhaled the musky aroma emanating from it.
After a few seconds, Karla raised her head and looked back over her shoulder. "Don't be bashful, baby. Just do what comes naturally. I'm eating your luscious cunt, so how about you gobbling mine?"
That seemed only right, since Karla was helping to turn Marcy's body into a mass of pleasure.
Karla's thighs were on either side of Marcy's head, the silken flesh touching her cheeks as they had once before. The auburn-hued cunt was resting against Marcy's lips, and a drop of spicy juice dripped onto her cheek. Marcy's tongue flicked out and tasted the warm droplet, and she knew instantly that she wanted more.
Now there were two active tongues in her pussy, racing up and down the responsive inner flesh. She imitated their actions, putting out her tongue to lick at Karla's pink pussy. Excited by the wet, slick feel of the membrane and the tickling of the soft hair against her face, Marcy became more bold. Her tongue slid into the opening, seeking the source of the rich aroma that was making her giddy with passion.
Her hand was still moving automatically on Kyle's shaft, and its throbbing rigidity thrilled her and urged her on. She automatically adjusted her caressing of it so that coincided with what her mouth was doing to Karla.
Marcy was filled with wonder at the delight of exploring the recesses of another woman's innermost being. It was incredibly erotic to feel the wet cunt lips flattened against her face, to have her mouth filled with the slippery tissue and ringlets of pubic hair – just as enthralling, she discovered, as it was to mouth a man's prick.
Her tongue was driving in and out of Karla, seeking the depths of her, striving to explore her to the fullest. Karla's whole pubic area was rotating wildly, rubbing the hot, slick flesh and wet, red hair all over Marcy's face. Marcy didn't mind at all, it just added to the passionate fire that was consuming her. It was as exciting as the feel of the talented tongues of the Karlows stabbing in and out of her in perfect unison. It was fantastic how they could keep together so well. It was even more fantastic how they could both find room for their heads between her thighs. But they had said they were the best brother and sister team in the world, hadn't they? They probably had had a lot of practice sharing the same steamy cunt or mouthing the same hot cock.
Marcy had instinctively speeded up her hand pumping of Kyle's hard shaft, and suddenly she felt it pulse strongly. Then her hand was filled with the torrent of his steaming semen. At almost the same moment, Karla bit down lightly on Marcy's clit, and the volcano erupted inside her, causing her whole body to vibrate in shuddering spasms.
"My turn, my turn!" Karla squealed, and Marcy's scream died in her throat as the other girl's cunt smothered her face. She licked furiously to bring Karla over the last lascivious edge. She was thrilled all over again when she felt Karla's shudder of climax, and then she was licking avidly at the spilled juice that accompanied it.
The three dozed briefly as they lay there, with the warm water lapping soothingly around them. But the Karlows weren't the type to rest for long. They were awake and ready to go again before Marcy was aware of having slept at all.
"Come on, Marcy," Kyle coaxed, straddling her and pressing his knees against the sides of her breasts. "Wake up, baby. Time for more fun and games."
