Incest/Taboo Backyard Pool

Amy laughed at her brother's attempt at a scientific answer to her question.

"There's still an island somewhere in the South Pacific where everybody walks around, naked, except that the men wear these things called 'penile sheathes'." Ron said. "They're these long, hollow tubes made out of wood or leather or something that they stick their dicks into. They tie them on with strings around their waists, making them stick up, looking like they have giant erections all the time. I guess the bigger and longer it is, the more status the guy has in the tribe."

Amy slowly shook her head, smiling.

Cocking her head to the side, she peered down at her brother's scrotum. Slipping her hand under it, she lifted his balls. She gently fondled, poked, and prodded them with a finger from her other hand. Ron groaned and his ass squirmed.

Amy looked up at him. "Is that all right, Ronnie?" she asked, concerned.

"Oh, yeah..." the boy replied, clenching his butt and thrusting his cock and balls upward. "It's not as good as when you touch my cock, but, as you play with my cock, it's nice if you stop and play with my balls little bit...or, both at the same time is good, too..."

He groaned and squirmed. "You have to be careful with them, though...they're very sensitive to pressure. While it feels really good when you play with them, if you do it a little too roughly, it can easily become uncomfortable, or even painful."

As Amy continued to gently fondle his testicles, Ron said, "As you've may have noticed, my ball-sack changes a lot, like when I go in the pool, it gets tight and firm, but in the sun it gets real soft and dangly."

"Uh-huh..." Amy nodded, "I noticed."

"That's because sperm are temperature sensitive," Ron said, returned to professor mode. "In order to keep them viable, when it's cold, your ball-sack tightens up and pulls your balls close to your body to keep them warm, and when it's hot, it loosens up and lets your balls dangle free, to cool them off. Natural air-conditioning. My scrot' is kind of half-way in between right now."

Amy, while continuing to fondle his balls in one hand, began running the fingertips of her other hand up and down along the side of his rigidly upthrust shaft.

Ron groaned and his butt squirmed.

Amy raised her eyes to look at her brother, smiling. "How come you know so much about dicks, Ronnie?" she asked.

Ron laughed. "Because I have one, of course!" he replied. "If there's one thing you need to know about guys, it's how important their dicks are to them. So, since I'm a guy, and my dick is very important to me, I've done a lot of research on the subject."

He smiled with amusement, as he watched his beautiful sister lovingly caress his throbbingly erect penis. She appeared quite fascinated by it, as well.

"Oh, yeah..." Ron said, off-handedly, "I happen know a lot about pussies, too..."

Amy looked up and smiled. "Oh, you do, do you?" she said.

"Yeah, uhhh...parallel research," he chuckled. "I'm actually very interested in pussies, as well."

"Well, I'm certainly happy to hear that!" Amy giggled. "It would be weird if you were only interested in dicks!"

Amy gently wrapped her hand around her brother's upthrust shaft and slowly slid it up and down several times. Ron gasped as a shiver ran through his body and he felt a tell-tale tingle deep in his belly. Afraid that he was losing control of his Tantric training, he quickly sat up, pulling his genitals away from his sister's hands.

"You sit up here, now," Ron said.

He helped Amy reposition herself so she sat against the headboard, propped up against the pillows. He left the room and returned a few moments later holding a hand-mirror. Amy smiled at the sight of her brother walking into the room, his penis still stiffly erect, pointed slightly upward from his crotch, bobbing and swaying as he moved.

Ron crawled onto the bed at Amy's feet. Grasping her ankles, he pushed her feet back, bending her knees and splaying them outward. He pushed a pillow beneath her ass to raise it even higher.

"Have you ever taken a really good look at your own pussy?" he asked.

"Uhhh, well...what do you mean by a really good look?" she answered hesitantly.

"Like this!" he said, holding the mirror above the girl's now wide-spread crotch.

"Here, you hold it...so you can get the right angle," he told her.

Amy gasped as she now saw her lovely little cunt, with its neat little tuft of blond curls at the top of her crevice, fully illuminated by the bedside lamp, in a manner she had never seen it before.

Amy felt a twinge of embarrassment at being so fully exposed, but then a thrill of excitement shot through her as she gazed at her own pussy in the mirror. She wasn't accustomed to seeing it, close up, from this angle. Her slightly puffy, outer labia were pulled apart by her wide-spread thighs and she could easily see the pink folds of her inner labia, glinting with moisture, inside the crevice between her outer labia.

Ron sat cross-legged, his shins pressed against Amy's buttocks. His penis was still fully erect, pointing upward from his lap. He lightly caressed his sister's slender, inner thighs as he, too, gazed down at her lovely vagina. He slid his fingers closer and touched them to her outer cunt-lips.

Slowly running his fingertips up and down, he gently caressed them, murmuring, "These puffy flaps on the sides are called the 'labia majora.' That's Latin for 'big lips.' Some women have hair growing all around here, not just up there on top, like you," he said, running his fingertip up and down both sides of her slit and around its lower end.

"I like how yours are all smooth and hairless...with just this pretty little muff of blond fur up here for decoration." He gently stroked his hand across that neat little tuft as if he were petting a kitten.

Amy, staring at her pussy in the mirror, thought about the close-up look she had had of her friend's vagina that afternoon. "I look different from Nicole, don't I?" she murmured softly.

"Yeah," Ron replied. "I suppose pussies are just as individual as cocks are. Your outer lips here...are a little bigger and puffier than hers are, so her inner lips are more visible, even when she not spread open like you are now. Her outer lips were a little darker than yours are, too. I think that due to her skin type. You're blond and fair while Nicole is brunet and slightly darker."

Touching his fingertips to either side of his sister's crevice, he gently spread her outer labia apart even farther, fully revealing her inner vulva, glistening with moisture in the light of the bedside lamp.

"Ahhhh...it's beautiful, isn't it..." he softly murmured as he gazed down into his sister's open vulva. He gently touched the tip of his forefinger to her inner labia and slowly traced it along those convoluted folds of soft, moist flesh. Amy gasped softly and her butt squirmed. "These wet flaps inside are called 'labia minora'. 'Labia' is Latin for 'lips'. 'Majora' means 'large' and 'minora' means 'small'."

"Ooooooh..." Amy breathed, her butt twitching as she stared at her cunt in the mirror, watching her brother's finger caress her soft, moist folds. Her eyes flashed back and forth between the reflection of her vagina in the mirror and her brother's penis standing upright between his crossed legs just beyond it.

"Down here..." Ron said, tracing his finger downward through her moist folds to where her outer labia converged at the lower end of her vulva, "is your vaginal entrance." He gently circled his fingertip around her joy-hole a few times, then carefully opened it.

"Ahhhh, yes! "he sighed. "I've always wanted to get a good look at one of these," he said, leaning down close. He lightly touched his fingertip to the thin membrane partially occluding her vaginal opening. "This is your hymen. I've never seen a real picture of one...just drawings."

Amy gasped and her butt squirmed as her brother caressed her taut-stretched maidenhead. He looked up at her and smiled. "Don't worry, sis, I'll be careful. We wouldn't want anything happening to that before you're ready!"

"Traditionally," Ron said, "that's supposed to break the first time you fuck. I understand that sometimes it can be tough and painful to break through. Other times, it's so fragile that long before your first time, it's been broken by doing sports or whatever. It appears to me that yours is still intact, though."

"See that? There's a little hole in it to allow fluids to pass through to allow for the vagina's self-cleaning ability. That's where the guy's dick has to go in the first time you fuck. It might just stretch to allow it to enter, or it might have to tear. It depends."

Amy groaned and her ass squirmed again.

Rod lowered his face a bit and extended his tongue. He swirled his tongue around the edge of his sister's vaginal opening, then delved a little deeper and licked her taut-stretched hymen. He located the little opening in it and gently worked the tip of his tongue into it.

Amy groaned and her butt wriggled as Rod pushed and probed with his tongue, gently stretching that little opening until he had worked a good portion of his pointed tongue through it. He thrust it gently in and out a few times, then he let it slip out. He licked her taut hymen a few times, then swirled his tongue around her vaginal opening and tenderly kissed it.

Ron looked up at his sister, smiling. "It seems fairly stretchy, to me," he said.

Amy groaned and her body relaxed, releasing the breath she had been holding.

Ron looked back down at his sister's vagina. "Ummmmm...your pussy looks so good..." he murmured, lowering his head and touching his extended tongue to the moist folds of her open vulva and began running it up and down though her dripping labia. Hunched over her crotch, his rigid penis was angled downward, its swollen head rubbing up and down along the crack of her ass as he bobbed his head up and down.

Amy watched in the mirror as the boy's tongue caressed her juicy vulva. She moaned softly and her body quivered with delight as she felt the smooth head of her brother's penis caress her butt-cheeks and tickle her ass-hole.

Fascinated, Amy watched as her brother's tongue tenderly explored the moist folds of her inner labia. After a few moments, she gasped and a thrill shot through her loins as his tongue came near the top of her vulva where her inner and outer labia reconverged again and he circled the pointed tip of his tongue around and around her clitoris.

"And here, of course, your clitoris, is the most important part, at least for you having fun," he said.

While Amy watched in the mirror, Ron gently pressed down with his fingertips on either side of her inner labia and the tiny pink nub of her clit emerged from its shroud.

Amy caught her breath and her body stiffened. "Oh, my gosh! I knew it was there, but I never saw it like that, before!" She stared in wonder at the little, pink bud, its head fully protruding from its surrounding folds of darker tissue. It was wet and shiny, glistening with moisture.

"While much smaller, your clitoris is structurally very similar to a man's penis," Ron said, resuming his instructor to student voice. "It has a head and a shaft, and, with stimulation, it swells up and becomes erect, although, depending on the individual woman, that may not be obvious because, unlike a penis, most of your clitoris is inside of you.

"Like a penis, at least before circumcision, the head of your clitoris is covered by a hood, or prepuce, which is similar to a man's foreskin. When sexually aroused, the clitoris becomes erect and the prepuce retracts and exposes the clit's head, just like the foreskin does on a penis. The hood is connected to your inner labia and when you fuck, your pussy-lips pull on the hood, causing it to open and close over the head of your clit, stimulating it."

Ron tenderly caressed the area around Amy's clitoris, then gently pressed down on either side. The bright, pink nub of her clit, glistening with moisture, protruded further from the darker skin of the surrounding shroud of its hood. He pressed and released several times causing the girl's clit to repeatedly emerge from, and retreat back inside its hood.

After a few moments, Amy groaned and her butt squirmed. Her clitoris no longer retracted completely into its shroud when he released the pressure on her labia, and, instead, remained slightly exposed.

"Ahhhh, yes..." he murmured. "See? When your clitoris becomes fully erect, its tiny head emerges from its hood and it can be stimulated directly." Leaning down, he touched the extended tip of his tongue directly to the glistening pink nub of his sister's clitoris.

Amy gasped and her body jerked. Ron gently flicked the tip of his tongue back and forth across her exposed clit-head a few times, then swirled it around and around its shrouded stalk.

"Oooooooh...ohhhhhh...ooooooh..." Amy moaned, her ass writhing, as her brother's tongue tenderly caressed her clitoris.

After a few moments, Ron raised his head and looked at his sister, smiling. She groaned, and her tense and trembling body relaxed as his tongue left her clitoris.

Ron sat up straight, feeling his cock throbbing insistently. He took a few deep breaths to settle his own rising passions, then, after a moment, he began to gently caress his sister's erect clitoris with the tip of his finger.

Continuing in his faux professorial voice, Ron said, "While the penis has several functions, such as: passing urine, delivering semen into the vagina, and for display, like those south sea islanders I mentioned, the clitoris has just one: providing pleasure to the woman during sex."

"Ummmm..." Amy purred, smiling. "There's another function of your penis that you didn't mention!"

"What's that?" he asked.

"Providing pleasure to a woman during sex!" Amy giggled.

Ron chuckled. "Oh, yes, that is, indeed, a major function of the penis, as well! My favorite one, in fact, now that my beautiful sister has introduced me to it!"

They were both quiet for a few moments, as Ron gazed down at his sister's lovely little pussy and she stared intently at his upthrust erection.

"Whew!" Amy gasped, her ass squirming. "I'm really appreciating that 'display' function you mentioned, Ronnie. Looking at your cock, standing there, all stiff and hard...it's making me feel all fluttery deep in my stomach...and my pussy feels all warm and squishy."

Ron looked up at her and smiled. "I'm glad to hear that, Sis! I understand that a lot of women don't like to actually see a man's penis...that's why they won't fuck with the lights on. They don't want to see it, they just want to use it!"

Amy laughed. "Not me!" she assured him. "I love looking at it...and how it makes me feel when I do!"

Ron smiled again. He looked back down. "Wow! I can see what you mean...just look at that!" He touched her hand to indicate she should look at herself in the mirror. "Look at how wet your pussy is now!"

Amy adjusted the angle for a good view of her cunt and gasped as she saw how her pink inner labia glistened with her sweet nectar.

Ron touched the tip of his finger to her vulva and tenderly caressed her moist vulva. "As I was saying," he said, resuming his lecture, "your clitoris is very similar to a penis. It has a head, and a shaft...except that in most women you can't see the shaft because it's inside your body. I understand that women, like men, are also 'showers' and 'growers', but the visible effect is reversed. While, I believe, most men are 'growers', I think most women are 'showers', meaning their clitoris engorges without significantly growing in size, except to push out its head a little bit. Some women, however, have a clitoris where the shaft actually extends a little ways out of her pussy when it gets erect...almost like a little cock!"

Ron was silent for a few moments, just gazing at his sister's vagina while gently caressing her soft, moist folds with his fingertip. "Oh, yeah!" he said, after a time. "A cool thing about your clitoris is that, while at one end its head sticks out, the shaft goes down inside you and the other end connects to the inside of your vagina in what is called the 'g-spot'."

He slid his finger down through her moist furrow to his sister's joy-hole. He located the opening in her hymen and gently and carefully inserted his already well-lubricated fingertip into it. He felt around on the upper wall of Amy's vaginal passageway, not exactly sure what he was looking for, while being guided only by what he had read on the subject.

Amy gasped and her body jerked.

"That must be it!" Ron grinned triumphantly as he continued to caress that spot inside his sister's vagina with the tip of his finger. He saw the pink bud of her erect clitoris pushing out farther from its hood. He lowered his head to caress it with his tongue as he continued to rub her g-spot with his fingertip.

Amy gasped and moaned, her butt twitching and writhing as exquisitely pleasurable sensations radiated throughout her loins. "Ohhhhh...ohhhhh...ohhhh..." she groaned, savoring the delightful sensations emanating from her vagina.

After a little while, Ron raised his head, smiling, as he continued to gaze down at his sister's lovely pussy. He slowly pulled his finger out, then slid it back in. The girl's cunt was very wet, the walls of her vaginal canal slippery with her juices, and his finger easily slid in and out of the well-lubricated opening in her hymen, tickling her g-spot with his fingertip each time he plunged it into her.

"Like I said before...when you fuck..." Ron murmured, his voice husky with his own rising passions, "the man's cock pulls and tugs on your inner cunt-lips as it goes in and out of your vagina, like this..." he said, watching Amy's clitoral hood retract from and then cover her tiny pink bud, "stimulating the head of your clitoris. Not only that, though... as it goes in and out, his cock also rubs its head back and forth across your g-spot, here..." he gave her g-spot an extra tickle with his fingertip. "That's why a man's cock-head is big and round on the top side...so it matches up with your g-spot, inside, on the front wall of your vagina."

Ron looked up at his sister. "And so..." he said, continuing to slide his finger in and out of her, "when you fuck, your clit gets stimulated on both ends at the same time."

Amy closed her eyes. "Ohhhh, yes..." she moaned, picturing in her mind her brother's penis sliding in and out of her cunt, its bulbous head caressing her g-spot with each thrust, just as his finger was actually doing.

"Ohhh...ohhh...ohhhhh..." Amy groaned. Her body stiffened and her loins exploded.

Ron vigorously thrust his finger in and out of his sister's wet, slippery joy-hole as the girl's butt bounced and squirmed.

Knowing that he had just induced an orgasm, he smiled with delight and self-satisfaction as he watched his beautiful sister's face grimace in ecstasy.

As her orgasm subsided, Amy's body relaxed. She opened her eyes to see her brother hunched over her wide-spread crotch, peering into her open vulva while still continuing to gently slide his finger in and out of her vaginal opening.

"Ohhh, Ronnie..." she moaned softly. He raised his eyes to see a broad smile spread across his sister's pretty face. "That was wonderful!"

Ron smiled back and returned his gaze to his sister's vagina. He slowly withdrew his finger from her joy-hole and very tenderly caressed the wet, glistening folds of her inner labia, while being careful to avoid the still protruding head of her erect clitoris, knowing it might be over-sensitized by her orgasm.

"God, Amy..." Ron murmured, "your pussy is so beautiful!"

The girl's heart skipped a beat. "Ohhh, Ronnie...do you really think so?"

"Oh, I sure do!" the boy growled huskily. He lowered his head and thrust his tongue into his sister's still open vaginal entrance, licking her hymen and sliding its pointed tip in and out of the tiny opening in that taut membrane several times. Then her ran it up and down through her vulva, gathering up the sweet nectar dripping from her tender folds.

Amy groaned and her butt squirmed as her brother's tongue caressed her moist labia, still tingling with pleasure from her orgasm.

Hunched over his sister's loins to lick her cunt, Ron's cock was angled downward, its engorged head thrust between her buttocks. It throbbed with desire as his taste buds, bathed in the sweet nectar of his sister's vagina, delivered an exciting message to his loins.

He looked up at Amy, smiling broadly, his lips and chin glistening with her juices. "Ummm..." he said, "and your beautiful little pussy tastes just as good as it looks!"

Ron straightened up, dragging the swollen head of his penis up across the puckered ring of his sister's anus, then through the lower edge of her vulva. As he leaned back, his rigid penis thrust upward from his lap. His eyes went back and forth from his sister's beautiful cunt and his own upthrust, throbbing erection.

Ron pressed his fingers against the base of his cock and bent it forward, touching its tip to the lower end of Amy's vulva. He slowly leaned forward, sliding the big, engorged head of his penis up through the girl's wet, slippery furrow and touched it to the exposed head of his sister's clitoris.

They both gasped as an electric-like shock shot through their bodies when the analogous tissues of his engorged glans and the head of his sister's erect clitoris made contact. He stirred the head of his cock around and around his sister's taut little love bud, then stroked it up and down through the moist furrow of her vulva.

"Oooooooh...oooooooh...ohhhhhh..." Amy purred as she felt her brother's big, smooth cock-head caress her sensitive labia. Thrilled by the delightful sensations, she watched in the mirror as that big purple knob, now wet and shiny with her own juices, plowed through her moist, satiny folds.

"Oh, Ronnie...that feels so good..." Amy groaned softly.

"Yeah...it sure does..." the boy agreed.

Ron pulled back a bit until the head of his cock was at the lower juncture of Amy's outer labia. He caressed the edge of his sister's joy-hole with his rubbery knob, then pressed it a little deeper, touching its tip to the girl's taut-stretched hymen.

Amy gasped and her body tensed in anticipation. A tiny voice in her head whispered, 'no', but her soaring passions shouted, 'YES!'

Ron, however, merely caressed that thin membrane with the tip of his cock. Then he pushed forward again, sliding his cock up through the juicy furrow of her vulva and thrust the bulbous head of his penis against his sister's erect clitoris.

Amy squealed as her loins exploded with yet another orgasm.

Ron vigorously poked and prodded his sister's clitoris with his engorged glans as the girl moaned and groaned in ecstasy.

As Amy's orgasm peaked, Ron pulled back from her clit and just slid the swollen head of his cock back and forth through the wet, slippery folds of his sister's vulva, gradually slowing as the spasms of her climax ebbed.

Rod slipped his hands under his sister's slender waist and pulled her body upward. Her legs wrapped around his back as he set her down on his lap. Their arms went around each other's body in a tight embrace.

"Ohmygod...ohmygod...ohmygod..." Amy gasped, her slim little body writhing against his as they showered each other's faces with kisses. Her cunt was still tingling with the residual spasms of her fading orgasm and as her butt writhed and squirmed, she felt the hot, solid shaft of her brother's erect penis pressed along the crack between her buttocks.

Finally, Amy heaved a heavy sigh of relief and her body relaxed. She gently ground her brother's hot, throbbing hard-on between the cheeks of her ass for a few moments, then she pushed him down onto the bed and scooted herself back onto his legs.

Ron's rigid penis sprang stiffly upright between her slender thighs. Amy gazed down at it, smiling. The boy's quivering organ looked hot, reddened even beyond its normal sun-bronzed hue. It glistened in the bedside lamp-light with her own copiously flowing love juices and a stream of his own pre-com flowed from the orifice at its tip.

Amy leaned forward and planted a kiss on the tip of her brother's bloated cock-head, then she climbed down off the bed and picked up her panties and tee-shirt.

As she slipped them on, Ron looked up at her, a questioning expression on his face as he held his hands around his upthrust erection in a gesture as if to say, 'What about this?"

Smiling mischievously, Amy said, "Tantric training...remember?" She turned and slipped out the door.
