Chapter 13
Robin, Polly, and Chris stood on the dock waving good-bye to the motor launch as it pulled away and headed toward the mainland. When the boat was out of sight, they turned and headed back toward the hacienda.
"Well, what would you girls like to do?" Chris asked them.
"Gee, I don't know, Chris," Robin said. "What would you like to do, Polly?"
Polly wet her lips and stared at his crotch. "I'd like to screw," she said.
Robin was shocked. "Polly!"
"Well, I would. And so would you, you know it," Polly said defensively. "After all, we're related to him, aren't we?"
Chris laughed self-consciously. All morning and early afternoon he'd been almost painfully aware that he would be stranded on an island here with two thirteen-year-old girls. Trying not to be obvious about it, he'd examined every part of their young female bodies and liked what he saw. Their legs in the bikinis were slim and nice-looking. Their bellies were slightly rounded, puckered at the belly button. Their breasts might one day turn out like Nina's and their mother's, but right now they were rather shallow - which didn't bother the seventeen-year-old youth because he'd humped his sister many a time and her breasts were not very big - especially when she was only thirteen, three years ago.
Robin pouted that she wasn't the one to suggest a fucking spree. She said, "We can do that later. I'd like to explore the island some more."
"I want to screw," Polly said. "What's left to see on this dumb island anyway? We've seen everything, haven't we, Chris?"
"Almost," Chris said.
"What do you mean, almost?" Robin wanted to know.
The boy hesitated. "Well, there are some caves that stretch back quite a ways underground. I have the feeling there might be some treasure hidden someplace down there."
Even Robin's eyes widened at that. "Treasure?"
"Sure," Chris went on. "There are rumors that pirates came through this area many centuries ago, left chests full of gold and jewels and never came back for them."
"Wow," Polly said in awe.
"But we can't go into the caves," Chris said.
"Why not?"
"Because I promised my father I wouldn't go into them. He thinks it might be dangerous." He shrugged and a smile blossomed on his face. "So I guess we'll just have to-uh--screw, like Polly says."
Polly shook her head "Uh-uh. We can screw later. Right now, I want to search for buried treasure."
Chris was honestly sorry now he'd mentioned it. He had no desire to disobey his father's orders. At a sudden thought said, "Let's put it this way, girls, if we don't have sex first, then I won't show you the caves where the treasure is buried."
"That's blackmail!" Polly protested.
"It's still early," Robin said. "We can do some fucking at the hacienda, then go into the caves, and when we come back we can celebrate by doing some more fucking."
"Well," Polly said reluctantly, "all right."
Chris breathed a sigh of relief. He'd delay having an orgasm as much as possible to make the sex act with the girls last as long as he could. Then when it got dark, it would be too late to go into the caves, and he'd put it off until tomorrow - when the others would be back from the mainland.
Once inside the hacienda, the twins headed directly for Chris' bedroom, each one of them holding onto his hand and pulling him. Robin's eagerness had returned, now that she was so close to having a fresh young male peter to look at, to fondle and pull and suck on and stick up her pussy. Uncle Ben had been a welcome change of pace, and now her cousin Chris would have some new flesh to offer. Polly felt very smug about her actions. Usually it was her sister Robin who was the bold one, but it was little Polly who'd suggested they do some screwing and who'd urged them to search the caves for pirate treasure.
In the bedroom, Chris allowed his eyes to roam over the bikini-clad twin bodies, the bare legs, the fledgling breasts under the skimpy halters. He recalled the pleasant daydreams he'd had of the two young females crawling nakedly over his responding male body, and he shuddered with anticipation.
Together they lay on the bed and started to kiss each other. Their mouths were warm and wet as they moved over his lips, and Chris returned their kisses with a great deal of enthusiasm. He'd vowed to not think of Nina-a vow he was having no trouble keeping, under the circumstances, as his hands roamed uninhibitedly over the twins' squirming bodies, fondling the breasts under the halters, delving between their legs to rub the thin cloth at the crotch. Their own hands busied themselves unbuttoning his shirt, unzipping his fly, unbuckling his belt.
He groaned as four hands grabbed his dick at the same time. "I think," he said, "we'd all better get undressed."
He quickly pulled off his own clothing while the twins removed their halters and bikini bottoms. Their bodies were smooth, white, slim, with rounded mounds of pubescent breasts, curved thighs, slim legs.
"You like what you see, cousin Chris?" Robin said flirtatiously.
Wetting his lips, Chris could only nod. The sight of all that naked female flesh made his mind spin. He didn't know where to begin.
"Well," Polly said impatiently, "are we going to screw or aren't we?"
Chris went into action. He lay on his back between the two prone girls and pulled them both against him. He alternately kissed one and then the other on the lips, inserting his tongue deep into the warm, wet opening with quick strokes. The girls returned his kisses just as passionately, while they rubbed their crotches against his leg and moved the nipples of their shallow breasts against his chest, tickling and titillating him. Their hands roamed over his dick and his balls, squeezing, kneading, while his own hands grew busy on their nipples turning hard with passion, and then between their legs where his fingers probed the dewy hot openings fringed with downy outcroppings of light pubic hair. He found their clits and, with his middle fingers imbedded in their vaginal lips, he rubbed the upstanding flesh with furious but meaningful strokes to which the twins answered with moans of delight.
"I want to suck it," Polly almost shrieked. "I want to suck his peter."
"Me, too," Robin moaned, sorry again she didn't think of it first.
"Be patient, girls," Chris said with a smile, "there's plenty for everyone." He reminded himself once again that he mustn't come too soon, or he'd have another argument on his hands about the caves. It wasn't going to be easy, for his dick was already up as stiff as it was likely to get and was throbbing like it usually did when he was on his way to coming.
Polly bent over her cousin's peter, holding the base of it in her slim fingers. The end of it gaped at her, with a slight trace of moisture welling in the tiny opening at the very tip. She extended her tongue and licked away the wetness with such enthusiasm the boy squirmed and almost pulled his peter from her grasp. But she settled her other hand around his balls to steady him and herself and bent forward more to kiss and suck on the end of the column of flesh she held rigidly in her grip.
Robin was not about to be outdone. She kissed Chris furiously on the mouth, then transferred her affections to his nipples, going from one to another almost frantically, remembering her father had once told her that they were erogenous zones on many males as well as on females. She remembered suddenly how her Uncle Ben had surprised her by fingering her asshole and then licking it as well as her pussy. It had been a thrilling experience she'd never felt before, having a man's tongue working over any hole other than her pussy, and it had been strangely exciting to her. Her cousin Chris' peter was not available, but maybe he'd like to have his own asshole licked!
She didn't bother asking him. She just dove over onto the other side of him and wedged her head under one of his legs, twisting her face around until she was facing his ass directly. From her vantage point she could see his balls and above that his stiff peter disappearing rhythmically into her sister's slurping mouth. Polly was hardly aware she was there, but Chris soon would be. She used both her hands to separate the cheeks of his ass, then eagerly she pressed her face forward. She'd come to like the musky smells of a man's genitals when he was sexually excited, and now new smells around his ass-hole drifted to fill her nostrils as she delved closer to the puckered opening. Impulsively, she planted a wet kiss directly over the opening and smiled to herself as Chris gasped. Not wishing to have him relax, she stuck out her tongue and quickly licked the opening all over before forcing her tongue inside with quick motions.
Chris shuddered and summoned all his strength of will to keep from coming. He could see why his father liked to have two young girls work him over. No matter where he looked there was a luscious piece of young female anatomy waiting for his touch or his kiss. At this time, Polly was busy cradling his balls and sucking his dick, while her sister Robin was lower with her tongue laying his asshole. Both of the girls presented their nicely rounded asses to him-Polly's to the left, Robin's to the right. Idly, as he felt his dick swell inside Polly's eager mouth, he ran his hands over the shapely asses aimed at him. The flesh was firm and smooth and warm. He moved his palms over them and down the twin cracks splitting the center. He could see the holes between their legs with delightful clarity, hanging there surrounded by wispy strands of wet, matted pubic hair. Simultaneously, his fingers probed the damp forests and crooked upward into the holes where the hot flesh quivered and sucked at him, while both girls moaned and murmured into his genitals.
He was going to come, he knew it. The combination of Polly's mouth frantically but expertly sucking his dick and Robin's tongue up his asshole were getting to him faster than he imagined possible "Wait!" he gasped. "Let's - let's do it the regular way.
Once again Polly was the winner. In a swift maneuver that surprised even her, she released his peter and rolled over on her back beside her cousin, after which she proceeded to pull him over on top of her. Robin was hampered by her ungainly position, and by the time she'd lifted up her head and whirled around, Chris was already between her sister's legs, which had clamped tightly about him.
"Hey," she pouted, "that's not fair."
"I'll do Polly first," Chris grunted, plunging his dick into the hole, "then you." He gritted his teeth and thrust in and out of the girl's vagina with rhythmic strokes, trying desperately to keep from coming. He buried his face in her long straight black hair and felt her rub her stiff nipples against his naked chest, felt her bump and grind her groin to meet his thrusting dick. He could feel her getting more and more excited as he pumped into her. Her heart beat rapidly and her breathing became erratic.
"Oh!" Polly moaned suddenly. "Oh, oh, oh, oh!"
She opened her mouth. wide and covered his lips with it as she pulled him close to her and spread her legs wide over his behind and flailed them vigorously in the throes of orgasm.
One humped, another to go, Chris thought determinedly. It occurred to him too late that if he'd come with Polly, he might be able to convince Robin to wait until his dick got hard again. That would take up enough time for it to get dark outside and too late for cave exploring. He said, "Next," and rolled off one twin.
Robin was ready for him, flat on her back on the big double bed, arms and legs spread eagerly to accept him and his body. As the weight of him crushed the breath from her, she scissored her legs at the small of his back while her hand guided his peter expertly up her hot, wet, and pulsing pussy. She squealed as he entered her fully, then she raked his back with her nails while she began a rocking motion under him.
Chris shuddered and clutched her rounded, churning ass with both hands. He tried to hold back but he could hardly think. Her loins pounded relentlessly at him and he could do nothing but plunge in and out of her at a rapid rate and hope for the best.
It was like a new experience for Robin. She hadn't particularly liked the taste of her cousin's asshole, but the mere idea of it was so sexy as to be very stimulating to her. Also, his maleness was new. The passion-contorted face hovering over her was an unused-to sight, as was the feel of his thick peter throbbing into her hot pussy. She appreciated this and so did her own body, for it grew very hot and sweaty and she felt the first gushing of orgasm exploding inside her so furiously her entire body trembled and she heard hissing sounds slithering from her throat and past her lips as she came in a series of spasms that seemed to not stop but to go on forever.
Chris grunted. Aware of the girl's orgasm, he knew there was little point in even trying to hold off. He didn't think he could have, anyway. He was already way past the point of not returning, and all it took was the thought to send him careening over the top. With a wild cry, he gripped Robin's ass in both his hands and began pumping swiftly into her until his dick grew even more swollen inside her and spasmed, spurting jets of semen deep inside his cousin's writhing body.
He was hardly through with Robin before Polly leaped up off the bed and said, "Okay, let's go find that pirate treasure."
Chris forced a laugh. "You've got a one-track mind."
"Well, you did promise," Robin reminded him.
"Yeah, I guess I did," Chris agreed reluctantly, "but -" He glanced out of the bedroom window, where the sun was settling quickly toward the horizon. "But it's going to be dark pretty soon."
"All the more reason," Polly said, "that we get started right away."
"That's right," her sister agreed, leaping from the bed to put on her bikini.
"We really shouldn't," Chris said. "My father says it's dangerous."
"Your father doesn't have to know, silly," Robin said. "He won't be back until tomorrow morning. Come on, before it gets dark. We can go into the cave just a little way."
"Oh, what are we arguing about, anyway?" Polly said, obviously irritated. "If the little boy doesn't want to go, we'll just go ourselves."
"But you can't do that," Chris objected. "You don't know where the caves are. You might get lost."
"If we do," Robin smirked, "we'll blame it on you.
"Yeah," Polly put in, "and we'll tell Nina what a fraidy-cat you were."
Chris sighed. It seemed he didn't have much choice in the matter. Well, he'd take them into the caves a little ways and then come back. He wanted to be on their good sides, because later he wanted to sleep with them and have them play with his dick and suck on it again. Besides, he didn't want Nina to think he was afraid of a dumb cave or of going against his father's wishes. As for that last, well, the old man didn't have to know about it, did he? "Okay," he said.
"Good," the twins squealed in unison.
Chris dressed, got a three-cell flashlight from a drawer, and led the way. The sun still hovered like a red eye above the horizon as they made their way through the clearing then across a heavily vegetated area of banana trees and tall, stately palms. A large outcropping of rock loomed before them. At the base was a small opening that was like a dark inkblot on the white rock.
"We'll have to crawl through there," Chris directed. "Once inside, we can stand up, though." He edged ahead of them. "I'll go first, since I've got the light." He got down on his hands and knees and started to crawl through the opening. When only his legs and ass were visible, a giggling Robin bent down and began tickling his backside. "Hey," his muffled tones came to them, "cut that out."
Polly, getting into the spirit of the thing, ran her hands between his legs, using the tips of her fingers to tickle his peter and balls.
Finally, he squirmed through, and they could almost hear him gritting his teeth inside the cave. He said, "All right, come on in."
"You first," Polly said.
"All right," Robin said suspiciously, "but don't goose me."
"I won't."
Robin got on her hands and knees and crawled into the opening. It was inky black except for a few feet yonder where she could see the beam of Chris' flashlight. Then she yelped as Polly's fingers slashed between her legs, rubbing her pussy with vigorous strokes. "That was a dirty trick," Robin said, when her sister stuck her head in.
"But it was fun, wasn't it?" Polly smirked. "You wouldn't have minded if it was Uncle Ben feeling you up."
Robin blushed. To change the subject, she said, "That's not much of a light you've got there."
"Yeah," Chris agreed. "I should've checked the batteries back at the hacienda." In the dim light, his face was worried. "I don't know Wow much longer the light will hold out, so we better not stay too long."
"We can turn back when we find the pirate treasure," Polly said.
"If we do," Robin remarked.
"We may have to try it again sometime," Chris said hopefully.
They worked their way through the tunnel which got larger as they progressed, until they could stand upright. The tunnel sloped downward, then upward, and then they faced several branches which Chris shone his light into. The beam reached only a short warm in, however.
"We'd hotter turn back," he decided. He flashed the light into Robin's face, then around. "Where's Polly?"
"I'm in here," Polly's voice came at them, complete with echoes.
"Well, get back here. We're going back home and have some more sexual fun and games."
Polly, crouched low in one of the tunnels, couldn't suppress a giggle. "I can't find my way back, come and get me."
"You know," Robin mused, "I've never been fucked in a cave before." She shivered. "It sounds so-so primitive. Like you're a caveman and I'm your mate."
"Yeah," Chris said, annoyed. "Well, we're all gonna get ourselves lost in here with your stupid sister around."
He elbowed past Robin and ran into one of the tunnels. Polly saw him coming and crouched even lower as he came in fast, flashing the dim light around the walls. Too late, she saw his anger at her was making him go too fast, and she shouted a warning. Too late, he stumbled over her and fell headlong. Instead of landing on the cave floor, he went on down, falling below the level they were at, the flashlight tumbling with him. They heard his bewildered and frustrated voice screaming loudly for an instant, followed by a dull sound of a body striking stone. Then there was silence.
Robin moved through the darkness toward her. "What happened?"
"There - there's a deep hole in the path," Polly said, trembling with fright. "I didn't know it was here. Chris fell into it."
Cautiously the two girls peered over the edge of the hole. Thirty feet below them the weak beams of the flashlight ironically played over the face of their cousin Chris, whose eyes were closed. A thin trickle of blood eased from his mouth and from the wound darkening his blond hair.
