Pausing only to shift position, she did the same to her brother whilst switching her hands onto James's cock. Kitty alternated sucking both boys in turn until they were quivering wrecks. Now Kitty was ready for some attention herself, so she lay on her back. As she spread her legs, she pulled James down alongside her and pushed his head between her thighs, hoping he would get the message of what she wanted from him. He did, and without hesitation, did exactly just what Kitty hoped he would.
Matt knelt next to his sister and kissed her once on the lips, his tongue playing with hers. Then he kissed his way down her neck over her shoulder and onto her boobs. Sucking and licking them, flicking her nipples with his tongue. Occasionally nipping at them with his teeth. The more Matt kissed and played with Kitty's boobs, the more excited she became, and the more excited she became, the more her pussy tingled and flooded with her juices.
James placed his face up close to Kitty's pussy, taking a moment to gaze at the sheer perfection of it. The thin outer lips, guarding that most intimate of places. Kitty was trimmed almost to the point of being shaven. The smell of her sexual excitement was wafting over James, increasing his lust and desire even higher. Despite having licked only one pussy in his life before, James had had a good teacher and so knew what to do. He blew a soft breath of warm air over Kitty's pussy before placing the tenderest of kisses on it. Kitty pressed her hips forward to meet him, but James pulled back, teasing instinctively. A second kiss, this time more forcefully, descended on Kitty's increasingly desperate pussy. This time the kiss stayed as James's mouth covered Kitty. A pink tongue pressed forward from James's mouth and licked up and then back down the length of Kitty's pussy, pushing deeply into her slit. Kitty moaned in delight, the vibrations echoing in Matt's mouth as by now he was kissing his sister passionately.
James' tongue continued to play with Kitty's pussy as she grew more and more desperate. Her orgasm was already building; she'd never got so close so quickly before. Her legs were now draped over James' shoulders as she held him in place. Her silken thighs tightening around his head. James's tongue increased both the speed and intensity it was licking at Kitty, delving deeper and deeper, pushing into her opening and swirling around. Kitty screamed and thrashed as her orgasm hit her. She was that forceful, she threw both boys off.
James didn't wait for Kitty to come down. His cock was throbbing and demanded to be buried in Kitty's sweet young flesh. He pulled her legs up over his shoulders as he knelt between her trembling thighs, took hold of his cock and plunged it deep into her. Rocking his hips back and forth as soon as he felt settled and secure. Her pussy felt hot and silky, like velvet. Her orgasm had made her incredibly wet, so there was no friction as James' hips powered his cock remorselessly in and out. Kitty was bucking and writhing as she fought to match James' relentless rhythm.
Turning her gaze to look at her brother, who was looking on in awe, as his friend pounded away at his sister, Kitty motioned for Matt to get closer to her. As Matt knelt next to Kitty's face, she guided his cock into her mouth and sucked on him.
Matt mirrored his friend's actions as he pumped his cock in and out of his sister's willing and talented mouth, knowing that he wouldn't last long. The sight of Kitty being fucked before his eyes, and the feel of her lips on his cock were too exciting and erotic for that.
"I'm cumming," he managed to gasp, allowing Kitty the chance to pull off if she wanted to. Kitty didn't pull off, if anything, she held him deeper in her mouth. Her lips, sealing around his shaft as Matt fired blast after blast of hot, thick, sticky cum down her throat. Kitty swallowed as much as she could, but she wasn't concentrating on Matt in her mouth; all her thoughts were on James and her pussy. The way he was pounding away into her and the sensations it was giving to her.
Matt had moved away from Kitty and James as they continued to... What? He couldn't describe it. The actions were fast and frantic, but there was a sense of loving between them as well. His sister and his best friend were making love together, hot passionate love, and he had a ringside seat. Hell, he'd even been involved. As he looked on, the intensity of the pair, the memory of Kitty's lips on his cock, and the way she had greedily slurped his cum down her throat began to get him hard again. Soon he was stroking his cock, ready for some more fun with his twin sister.
James felt Kitty's pussy clench down tighter as her second orgasm overtook her, triggering his own release. James felt his balls pull up into his body as his cock incredibly seemed to grow bigger and harder at the second he exploded. Cum raced along his shaft, jet after jet spurting out of him to fill Kitty's pussy. James held himself steady as he pumped Kitty full of his hot liquid. Eventually, he pulled out and fell to the side, a trickle of his cum escaping Kitty's pussy as it slowly closed.
Matt didn't, or couldn't wait. He grabbed hold of Kitty, flipped her onto all fours, facing away from him and, ignoring the fact her pussy was full of his friends cum, slammed his cock deep into her. Kitty screamed out in ecstasy. Still in the throes of her receding orgasm, she responded instinctively.
"God, yes," she screamed as she obeyed her body's primal urging. Matt gripped Kitty's hips and used them to pull her back onto him. Time and time again, he fucked in and out of his sister's pliant body. Matt knew this was wrong; this was incest. Taboo, possibly the greatest and last taboo in the western world, but he didn't care. Kitty had clearly invited him to take part, and never once had she tried to stop him. That turned Matt on even more. Who would have guessed his sister was so hot and kinky.
Kitty was thrusting her hips back at Matt, matching his impatient movements with more controlled, but equally forceful and lust-fueled moves of her own. At the same time, she was busily cleaning James cock of her own juices and the last remnants of his cum. She loved the taste of their combined juices. She'd never done anything like that before. Yes, she'd sucked cock and had let guys cum in her mouth, but she'd never cleaned a guy up afterwards before now.
As she let James slip from her mouth, she sensed Matt was on the verge of cumming and shouted out, "Matt, don't cum in me for fucks sake. Use my mouth, or cum on my tits, but don't cum in me."
Matt had enough control, and Kitty's timing was perfect as he was just on the verge of exploding. He pulled his cock out of his sister's pussy and splashed his load over her belly and tits. Groaning as his hand was a blur on his cock as he stroked it to a finish.
All three exhausted and happily sated teens collapsed in a tangle of hot, sweaty bodies as they recovered. Kitty looked over at the two boys without any sense of shame at what they had done, smiling as she joked. "Why the hell did we not do that before? Oh yeah, there's this guy's code of not hitting on your mate's sister. Isn't there a guy's code that you shouldn't hit on your sister as well?"
Matt managed to regain enough of his senses to reply, "I think it was you hitting on us two."
Matt's cum had dried on Kitty's body, leaving a sticky stain, so she got up and ran down to the sea. Plunging in, she swam around for a while, allowing the warm salty water to cleanse her skin. The water didn't cleanse her mind of the thoughts running through it though.
Kitty took her time making her way back to the secluded place where the boys were, at the same time allowing anybody who wanted to admire her sensuous body. She thought she saw a pair of older women, one dark-haired and curvy, and the other slender and blonde emerging from behind some rocks adjacent to where all the action had taken place. Kitty realised with a start that if the women had wanted to, they could have seen and heard everything that had been going on.
She was too far away to distinguish the women clearly, but she turned cold as her heart filled with dread. She had a very good idea who they were.
