Cindy grinned at him, then reached out to curl her small hand around his limp prick. She gave a little gasp of excitement as she did so, and Rick sighed because her cool touch felt so nice. Cindy wasn't really sure she knew how to make her brother's cock hard, but she remembered yesterday and how Daddy had seemed to enjoy it so much when she touched his big swollen peter and put it in her mouth. She'd simply try the same thing with Rick.
For a few minutes she played idly with his floppy white prick, pumping it in her hand and gently working back the foreskin for a look at the pretty bright red nut beneath. Rick had a very handsome cock, she decided, even if it was a little small. But Cindy, a natural thrillseeker, was quickly bored with this game and wanted to get on to the main attraction. Moving onto her knees, she bent over Rick's taut belly and brought his limp meat into her mouth, sucking it all the way inside. Immediately the sensation excited her sharply, and she began to suck him hard and swiftly.
"Uhhhhh!" moaned Rick, arching his body to dig his excited prick into the fleshy wetness of her mouth. "That feels great, Cindy!"
He wondered where his little sister had learned to suck cock, but actually he didn't care very much, just as long as she kept doing it. What a lucky break that he had accepted her bet! He'd never dreamed he'd get a repeat of yesterday's fun, not with Cindy! He closed his eyes and sighed blissfully. He felt himself rapidly growing hard. So what if she won a dollar off him? It was worth a dollar, and much more, to experience this delicious pleasure.
Cindy gurgled excitedly as she felt her brother's penis growing long and rigid in her busily sucking mouth. And she wasn't thinking about winning the bet, either. She simply liked the feeling of sucking his rod, liked the light salty taste of the cream that now began to ooze from his glans. Yesterday Daddy's thick hot cum had almost choked her, and it was much stronger-tasting than this, yet she had enjoyed eating it. She wouldn't mind repeating that experience.
As she continued to suck him hotly, wetly, Cindy decided to satisfy the rest of her curiosity about male bodies. She hadn't really gotten a good look at Daddy because everything had happened so fast. Now she could take her time, since Rick seemed to be in no hurry at all. Gently, she slipped her hands between his slim, muscular thighs, urging them apart. Rick understood and obeyed, opening his legs wide for her. Cindy gawked at what she saw. It certainly was nothing like her own equipment. His rosy testicles hung limply in their finely-ridged sacs, and between this prominent feature and his brownish anus there was nothing but flat space. Cindy felt briefly superior. Where a girl's vagina was, boys had nothing. On the other hand, she couldn't help envying Rick his handsome little penis. It must be a great convenience when you had to pee. She sucked his cock with an almost slavish touch of admiration, and at the same time she gently petted his hot, limp balls. To her surprise and delight, the flaccid little sacs began to fill and stiffen as she petted them, and Rick seemed to enjoy her touch immensely. He sighed and moaned and wiggled, and when she cupped the now-stiff bags and began to mold them in her hot little palms, he groaned with deep delight.
"Yeah, Cindy!" he said. "Play with me, play with my balls! Ohhhh, man, that's good!"
His cock seemed to grow even harder on her tongue, and cream dribbled steadily from it. Cindy eagerly swallowed it all. She couldn't keep her hands still now. Giving his swollen testicles a final squeeze, she moved on to probe and tickle his anus, thrusting her little finger deep inside the tight tunnel. To her amazement, as she sunk her finger all the way into his asshole, Rick yelped and began pumping her mouth full of his cum. She gulped it all down, and when his shrunken meat slipped at last from her lips, she licked it clean, just as she had done with Daddy.
"Well," she said, "do I win the bet? I mean, your cock's not hard any more, but it sure was hard for a while there!"
Rick giggled. "Yeah, you win! I owe you a buck. Oh, wow, that was fun. Here, Cindy let me show you something."
For reasons he didn't understand, perhaps gratitude or curiosity, he suddenly wanted to try on his sister all the things he'd done to his mother, things which had excited Betty into a wild, mindless state of lust. He wondered if he could achieve the same results with Cindy. He gently laid her down on her back and scrambled between her legs, jamming his mouth down on her tiny soft dark snatch. Cindy giggled and wiggled, but she opened her legs quickly enough when she saw what he wanted to do. She wondered if he could give her the same wonderful sensations Daddy had given her with his fingers and tongue. That would be out of sight!
Rick parted the furry lips of her mons and found the tiny red bud of flesh which he had discovered to be the source of his mother's deepest pleasure. Cindy's wasn't nearly as big as Betty's, but he quickly discovered that it was no less sensitive. As he placed his stiff tongue tip on the raw head of her little clit and began to tickle and massage her there, Cindy gave a piercing shriek of delight and instinctively threw her legs up over his shoulders, giving him complete access to her eager pussy. Sensing her sharp excitement, Rick jammed his mouth onto her wriggling red bud and sucked it for all he was worth. The noise was loud and juicy, and even this seemed to excite his little sister unbearably.
"ooooooo!" she squealed. "I love it, Rick, I love it! Don't stop!"
He didn't. Sucking her clit as fast as he could, he felt her cream bubbling out to soak his chin, hot and sticky, just the way Betty's cunt had creamed on him yesterday. Rick was very proud of his newly-acquired talent for turning girls on, and now he decided to go for the big prize, giving Cindy an orgasm. He had achieved it with his mother by putting his fingers in her vagina and pumping stiffly, so maybe the same thing would work with Cindy. Fumbling around, he finally managed to locate the tiny creaming hole and he slipped the tip of one finger inside. She was much tighter than Betty, and his probing finger seemed to give her some discomfort. He quickly withdrew. Obviously he would have to find another way to bring her off.
Then he thought of the delicious thing his sister had just done to him, sticking her little finger in his ass. He didn't understand why, but it had made him shoot instantly, like a bomb. Now, lubricating his finger with her abundant pussy juice, he wiggled the finger inside her tightly-clenched little rectum, sticking it in as far as he could.
"Oooooooo!" wailed Cindy, arching her slim body up to him. "Oh, wow, Rick, that's great!"
He grinned to himself. Working his finger steadily in her asshole with a loud squishing sound, he went back to sucking her clit as well, bathing it hotly with his spit and stimulating it with his stiff tongue. Cindy panted loudly and creamed more abundantly than ever. Then suddenly her little body arched sharply, stiffly.
"Eeeeeeee!" she screamed.
Steaming cunt juice splattered out to wet Rick's face as his little sister writhed and squealed in violent orgasm. She was jerking her pelvis so hard that he had to cling tightly to her to keep his mouth on her wriggling little clit. At last the exhausted, happy girl gave a deep moan of satisfaction and sank limp into the grass. Rick was surprised to notice that her tits seemed larger now, swollen with arousal, the little pink nipples standing straight and stiff.
She smiled lazily up at him. "You look silly," she said. "You've got gunk all over your face."
"That's your fault," Rick said and grinned. "You damned near drowned me."
He dipped his hand into the pool and rubbed the cool water on his face. Cindy just lay there, her legs spread wide, letting the friendly sun warm her slightly bruised pussy. When Rick came to lie beside her again, she sighed happily and snuggled close to him, affectionately petting his limp cock.
"Golly," she said, "that was fun! We sure won't have to be bored on this camping trip from now on!"
"You better believe it!" Rick said. "But we've gotta play it cool. Can't let the folks find out what we're doing."
"I know!" Cindy said. "What's their hangup, anyway? First they tell us all about sex, and then they don't seem to want us to do it."
"Well, that's their problem," replied Rick, fondly rubbing her swollen little tits. "And as long as we're careful, we can have all the fun we want."
Brother and sister lay drowsily, contentedly, in the sun, letting its warmth soak into their naked bodies, lazily petting each other. Very gradually Rick's young cock began to revive under Cindy's persistent massage, and Cindy felt herself growing horny again as Rick tweaked and ribbed her sensitive nipples. She pumped his cock till it was quite rigid again, sticking straight up from his belly.
"Rick," she said, "I have a great idea!"
"Ummmm?" he murmured.
Cindy gave his stiffened cock an affectionate tweak. "Let's find out what it's really like, Rick. I mean, let's actually do it."
Rick gawked at her, scarcely believing his luck. At last, the long-awaited chance to lose his virginity! Of course, she was only his sister, it wasn't as if he'd made a real conquest, but he certainly wasn't going to turn up his nose at an invitation like this.
"Why, uh, sure, Cindy!" he said.
She grinned at him. "Okay, so do it to me."
Rick grinned back at her for a moment, and then his face fell. It was humiliating to admit it even to himself, but he really didn't know where to go from here. He'd never gotten that far with a girl before. All he knew, from having once sneaked into an X-rated movie, was that the man was supposed to he on top of the woman.
Not wanting his little sister to notice his confusion, Rick put on a manly, confident look and crawled on top of her. It was kind of exciting the way her hard little tits poked against his bare chest, and he could tell that she was excited, too. She grinned and giggled and writhed impatiently beneath him. But he still didn't know exactly how to proceed.
"Oh, come on, Rick!" she gasped. "Do it! Fuck me! Put your cock in me!"
As calmly as he could, Rick seized his swollen your penis and began to maneuver in the wet slick tissues between her legs. Cindy squirmed with anticipation, while he wondered desperately where her cunt was. He just couldn't seem to find the damned thing.
"Ohhhhh!" wailed Cindy. "What are you waiting for? Here, dummy, you put it HERE!"
She lodged the head firmly into the wet indentation of her vaginal mouth. "Now push!" she groaned.
Shivering with excitement, Rick pushed – and nothing happened. He just stayed right where he was. He pushed again, using all his strength, and still nothing happened. Her little cunt was just too tight.
"Oh, damn!" he cried. "There's not enough room, Cindy, it just won't go in!"
She gave a little sob of frustration. "It's because I'm a virgin, I guess. There's supposed to be something in the way, the hymen I think it's called. You have to break through it. I'll push, too, at the same time. Ready, set, GO!"
Rick rammed his aching cock forward just as Cindy slammed her pussy hard against him, and there was a loud pop. "OOOOOOO!" gasped Cindy.
Rick looked down at her, slightly cross-eyed with sudden pleasure. He had broken through, all right, and now his cock was deliciously buried in her hot, tight little sheath. He began to move it in and out, moaning his joy. At first Cindy grimaced with pain, but after a few moments her face softened, her eyes glowed, and he felt her clinging vagina creaming hard all around him.
"Oooooohhhh, Rick!" she whimpered. "It feels so good! I just love it! Do you like it, too?"
"Oh, man!" sighed Rick. "It's the greatest! I love it too, Cindy!"
He was no longer confused or embarrassed, no longer worried about how to proceed. It was simple, deliciously simple, you just did whatever felt good. Like magic, Cindy seemed to enjoy everything he did to her. When he obeyed his urge to dig deeper into her and to ball her as hard as he could, she shrieked her pleasure and ground her creamy little cunt all around his impaling tool. They were so excited, they climaxed together in a matter of minutes, Rick howling and squirting his cum hotly into his sister's convulsing cunt.
"Oh, wow," said Cindy, hugging him affectionately, "that was wonderful, Rick! Let's rest a little bit and do it again!"
They fucked all day, and around four o'clock they staggered back to camp, flushed and goggle-eyed with pleasure, just in time to do a quick clean-up and start supper before their parents returned. Herb arrived first, dragging and tired looking. He opened a beer immediately and sank into his chair. Betty got there shortly afterward, looking hot and exhausted and ill-tempered. Nevertheless, she managed a smile for her children. They looked so flushed and healthy and happy after their day outdoors.
"Well, you two," Betty said, "I hope you had a nice day."
"Oh, yessss!" Cindy said. "We had a wonderful time, didn't we, Rick?"
"We sure did!" the boy exclaimed. "Nothing like getting back to Nature!"
Herb smiled, too. "I'm glad to hear that," he said. "I'm glad you kids are changing your mind about this vacation."
"Oh, Daddy," cooed Cindy, coming over to kiss his cheek, "it's the best vacation I ever had!"
"Well, my goodness!" Betty said. "What made you two change your minds like this?"
"Aw, nothing much," Rick said and shrugged. "We just discovered a great new swimming hole."
He turned his back on his parents and winked at Cindy.
