Chapter 4
"Hi!" Dennis burst through the door of Room 5 and strode excitedly toward the lab counter where his sister was again busy with her microscopic study.
"Hello." She snugged the smock together with the paper clip and turned to him, arms extended in welcome. "Come here."
When she had left home for nurse's training a few short years earlier, Dennis would have disdained the opened arms of a female. Now he strode confidently to his sister and gave her an exuberant hug.
"Oops, sorry!" he exclaimed when they broke and he saw his bear clasp had torn the clip holding her smock together. "Lemme find it." Face coloring, he dropped to his knees to search and she caught his arm and pulled him to his feet.
"Silly, you've seen me in practically nothing at all lots of times at home." She caught his "gawking at the goodies poorly hidden under the smock. "Let's show you my workshop."
After a thorough tour of the lab, including a bounce testing of her daybed and a try at the instrumentation for measuring and grading chemical components and a jump on and off the scales which told him he was too thin, Dennis spied the broom and pan.
"You go ahead and work, sis. I'll sweep the place up. Looks like no one has been janitoring the joint for a year."
"Thank you, Denny. You're a dear." She patted a Kleenex to her forehead. "No one has checked the air conditioning in here for longer than that, it feels like.
You mind if big sister works in her unmentionables? I've just got to finish my experiment before supper."
"Sure, go ahead." He hummed "The Stripper" as she peeled the smock, but his voice cracked when he saw the form he thought he knew so well. Housed in the transparent bra, her fantastic breasts were twin globes of luscious girl-meat to the fourteen-year-old. She angled toward him and he fought to catch air as he took in the sense-dazing sight of dark bull's-eyes, the centers of which jutted hard against see-through nylon. His glance, dropping, swept fabulous turned hips and the devastating prominence of her mound.
"I'll work on my slides for awhile then," she said quietly, not missing the urgency along his slacks leg as she settled onto her high stool.
He brushed ferociously at the floor and the action simply aggravated his problem and his self-consciousness when once he saw her look into the mirror, very directly and solemnly observing his fierce bulge.
"Want to see my study program?" she asked, nonchalantly beckoning him to her side.
"Yeah, hey what is that?" He stared through the microscope at the swimming forms in the blob on the slide glass. "About a thousand to one magnified, huh?"
"More than that. Do you know what it is?"
"Uh-unnnhh."
"Semen."
"Ahhh ... no kidding? That's ... wow ... why you studying that?"
Kitty looked thoughtfully into saucer-wide eyes. "It's to understand the male responses better. To understand all men better. See, no one has done much research on the male sexual responses and the Merriweather Hospital Graduate Committee has granted me a scholarship to do this."
"Wow! Far out!"
She arched worried eyebrows at him. "Except for one thing. You won't think me awful if I ask you to keep a secret between us?"
"No way you could ever be awful." His eyes pleaded to be trusted. "What's the secret?"
"I need a young male for the key control figure in my study and research and I don't know where to get one with no hang-ups and no wrong ideas."
"What kind of young male?"
"About your age."
"What's he got to do that would give him wrong ideas?"
There was an electric silence as Kitty let the tension build, swiveling slightly to partially face her brother. She could feel the same sex-dynamic vibrations pulsing from him as she felt each time she was near Barry. Her hand reached to his wrist, paused, then drifted slowly to his crotch and found the ridge pole that extended painfully swollen against the in-seam of his slacks.
'The wrong ideas could come from my doing to him and demanding of him to really let himself go. Of course, he would be paid for his work and he could think of it as being my employee."
"Paid?" It was a crack-voiced squawk that broke from Denny's astonished lips. Too passion-stung through all his fourteen-year-old frame to move when her hand touched the denim covering his erection, he simply stared. "Paid for what?"
"The grad school has a grant. Want me to show you where?" Her eyes, sympathetic with his panic and ready to understand if he should react negatively, looked quietly into his. Large and dark and totally innocent. "You don't have to do this, Denny." Low sultry invitation to leave.
"Oh gee, I think I want to. I do want to. Show me." He crossed his arms and stared down his front at the fingers fumbling with his slacks zipper. . "Our secret then," she murmured. "About everything we do here and about your being on the payroll."
"It's nobody's business but ours, right, sis?"
"Right." Her thumb and forefinger had the zipper lock and quickly she opened the fly, talking as she did. "You know, you don't seem like Denny to me anymore. You're more than six feet and you're much older looking. It should be Dennis."
"Guh .'.. golly, Kitty, that's ... gosh!"
Her fingers prowled through the fly and under the elastic edge of his jockeys, finding the stiffened column of his cock and forcing the painful hardness toward freedom.
"Dennis, that's not really you!" She released her light-fingered clasp of his erection the instant it sprang into view and he saw her hand dart to her mouth in unpretending surprise.
"I know," he admitted glumly. "I'm really disfigured. I get plenty of looks in the gym showers, so I know I'm kind of freakish looking."
"Whatever are you talking about?"
"Well, look at it." He glared at the horny hugeness bolting from the darkness of his fly. "I'm almost a foot long like this. Betcha Barry isn't even that gross!"
"Gross? Dennis, that is just about the most beautiful penis I have ever seen."
His eyes danced happily. "You're kidding, but thanks." He yanked his tee shirt over his head and reached for his belt. "You won't even admit you know me when you see what a skinny rail I am and how this thing of mine looks against my bare naked body."
"Show me." She pushed him toward the corner with the daybed. "I'm going to go lock the door and then I'm going to come see what a malformed brother looks like."
At the door she pretended to fumble with the lock, then called over her shoulder, "Ready."
"You'll be sorry," he warned.
Very slowly Kitty spun on a high pump heel and focused on the daybed. There, prone on his back, slender-bodied, with arms and legs akimbo, sandy-haired Denny watched intently for her first visible reaction. It was explosive admiration.
"You absolute doll!" she squealed, moving with deliberately suggestive sexiness across the room and standing directly at the side of the cot. "You are gorgeous, Dennis!"
He beamed. "Don't think I'm a ridiculous beanpole?"
"Anything but." She reached for the right words to put him totally at ease. "You're athletically slim and you remind me of those Olympic runners in the statues in Athens. You have what every man wishes he had in trimness of build and in . . . oh, goodness, Dennis, every male in the world would love to have all this." She sank to the edge of the cot and cupped under his loaded testicles, hefting upward to accent the massiveness of his equipment.
"Careful!" he exclaimed. "I ... I'm sure you're going to think this is spacin' out, but I ... I ..." He was panting. "I can wing it without even touchin' myself."
"Now you're kidding," Kitty accused, nevertheless releasing the well-swollen balls and gaping at the aroused youthful lust. The prick, with its frantically distended cap contorted like a swollen mushroom and dark red in color, was indeed a freakish asset on her brother's front. The testicles, nestling now like twin sacks of chamois loaded with precious diamonds, rested in the crease of his thighs.
"Sack!" she whispered aloud, staring at the balls. "That's it-S ... A ... C ... K!" . "So? I got two of 'em. Guys call 'em balls." Dennis . was obviously feeling much more at home with his sister.
"No, I was thinking of something else-it doesn't matter. But I don't believe you ... about the winging it without touching yourself. You mean you can actually ejaculate by spontaneous combustion?"
"Want proof?"
"I want proof," she agreed, going to the rack for a glass tube. "And when you wing it, as you call it, I want some of it in here."
His gaze had a kind of hypnotized disbelief as he took the tube in his hand; then he stared fixedly at her crotch.
"You've seen many girls almost naked, haven't you?" Kitty asked him.
"No, sir ... ma'am ... hot dawwhgg! Sis, you're somethin' else!"
His thin frame visibly tightened and she saw him arch against the first mattress, the middle of his body lifting from the cot as he gaped. "Gonna show you I don't he. Watch him ... now, watch him!"
His phallus, darkening still more with the pressure of the aroused blood trapped in its length by tightly squeezed groin muscles, was a formidable tower of bristling cockflesh. So brimming ripe to display its capacity, it quivered lonely and untouched in a trembling pendulum swing. Each arc of the stallion-like prick made the protruding veins and arteries that laced its length stand out even more prominently.
"You really can't mean it will reach climax without-"
"With ... out... nothin' ... seeee!" Palms pressing from under his slim buttocks, Dennis urged his body into a contorted arch the instant he felt the charging semen. Unnoticed, the test tube dropped to the mattress as he ogled his sister's body, enthralled. The ejaculation shot in sparkling arrogance from the stud-length, its first bolt leaping several feet from the penis and slashing across Kitty's shoulder.
Her dumbfounded disbelief was stung into action with the feel of the warm cum. "Test tube! Test tube!" she squealed, then, not seeing it, she dove for her brother's middle and, unwilling to let the gorgeous fountain of youthful sperm spray aimlessly, aimed it at her mouth.
Incredulous, Denny heaved to his elbows, watching in disbelief as his sister ovalled her lips wide to catch most of his discharge in her mouth. He humped against the mattress and let himself go in the most rapture-ridden crest he ever had reached.
She moved quickly from the cot the instant he finished and, panting, he gawked at her sleek ass as she grabbed for another test tube. Only then did he feel the tube he'd dropped that had slid under his body. Kitty let the mouthful of semen drool slowly into the glass, wishing she could swallow it and wondering why she had the strange ecstasy of nearly climaxing herself just at the feel of the spasm-driven penis in discharge. Was it the touch of his erectile tissue against her lips, she wondered, or the spray of his love of her mouth? She knew she was as much a different female as Dennis was a different male.
"That was really quite beautiful Dennis." She walked slowly back to the cot where he lay fondling his genitals unabashedly. "Do you do it a lot?"
He grinned. "S'what I mean about bein' a freak. I can make myself come least five times a day."
"How long have you been masturbating?"
The shrug was a kind of embarrassed cover-up. "Tell you the truth, I'm a kinda late starter from the way the other guys talk. I only began this year."
"And you haven't done it with a girl yet?"
"Honest, never. Most of my friends haven't either." He flushed. "I don't even know how to."
"Would you play with it more for me?" She looked him squarely in the eyes as she asked. "I mean for pay. You'd have to do it lots."
"Wow ... oh man, would I?" There was a creeping, snakelike elongation of the softened penis in instant response.
She toyed light fingertips through his pubic down. "I'm thinking about another idea for you but I want to see if you really can keep what goes on here secret Someday soon I may surprise you, but till then . . ." She rose slowly from the edge of the cot stretching to accent her fabulous contours, maddening Denny's cock to full hard. "Meanwhile, I want samples of as many jerk-offs as you can give me each day here. HI invent ways to maybe make it more interesting, but you masturbate over anything that excites you. If it's one you dig and you want to bang me with it or do funny things to me to turn yourself on, do it. You can't insult me. Just get some of your semen in a test tube each time and label it one or two or five or whichever time it is. Okay?"
"Honest? I get paid for that?" His eyes studied hers for a hint of mirth and, finding none, grinned when she nodded. He groped under his tail for the test tube and mumbled something about misplacing it first time. "Sit down and lean over me," he commanded, motioning to the edge of the cot.
She obeyed and he clasped a fistful of long dark hair. "It's beautiful. Know what I sometimes dream about doin'? I'd like to hold a handful of your hair around it while I frig it. Wow! I'd be careful not to hurt, okay?"
"I said anything goes and I meant it. It doesn't even matter if it hurts a little, just so long's I can see it happening." Kitty snatched the strands of her hair he held and swinging her head she swirled the long dark lengths across her shoulder, catching a handful at the end. "Gimmee!" she demanded possessively, reaching for his erection.
"Whatcha doin'?" cried Denny, delighted as she wrapped his prick in a tourniquet of brunette hair, snugly braiding it at the base of his erection.
"An experiment," she declared matter-of-factly. "Is it a nice feeling?"
"Blows my mind."
She looked soberly at the unhinged passion on the face of her brother wriggling on his back. "You know, back in the old torture chambers of castles?" Her fist tightened on the hair noose, tugging upward, and she noticed that his body followed.
"Yeah ... yeah, what about 'em?"
"I know you're big on history and probably read a lot about how they treated prisoners. Did you ever read about how they used pretty girls for very special prisoners they wanted to die happy?"
"Uh-unnnhh." His eyes fixed briefly on her lips to see if she was teasing, then, convinced, he looked back at her fingers braiding the dark tresses around the full circumference of the base of his tumult-driven penis. "So, c'mon ... tell me about the special prisoners."
"Don't want to frighten you, so stop me, if it's too awful. They all were shootin' their cum when they died."
"Oh ... jeez!" His prick went steel hard against the braided brunette and the vermilion of the cap darkened several shades as the tip ballooned visibly.
It was obviously a cum-on and Kitty saw the perfect way to produce some of Denny's most potent responses. A "late starter" he'd called himself, not yet able to control the persistent desire to play with himself and still not educated in the act of coitus, Dennis Carr was the perfect adolescent male. And as a bonus, he wore a cock fully as big as Barry's.
It meant that in Kitty's family there were two stallions whose main thoughts every day were centered on her. What it would be, she thought, to be able to teach this tower of erected flesh how to copulate! What it would be to maybe even sometime have both Barry and Denny on the same day stuffing their impossible erections deep into her vagina.
The sudden flash of guilt attacked the lust. Coitus with Barry was in the family and it was his idea not hers, she reminded herself. Even if she was doing it happily with Barry now, she herself couldn't dare involve Denny in going as far as incest. Never!
"Tell me ... come on ..." Denny pleaded, breaking her thoughts and dragging her from the future to the present. "What'd the girls do with their prisoners?"
Carefully, Kitty completely braided the locks of her hair in miniature noose fashion around the bonelike shaft. To Denny it was a delightful trap, till she straightened suddenly, dragging against his thoroughly bound prick and forcing him to a fast reflex arching.
"They did that!" she snapped and her expression was unsmiling. "Enemy males were turned over to the young girls and, in sending them to their happy hunting grounds or wherever enemy soldiers went, they did this with their hair and this with their mouths." She bent across his rigidly prostrated nakedness and engulfed the fat crown in her lips.
"Eeeyowww!" He trembled violently as she spewed the saliva-soaked organ into view. "That's wild. Like kissin', only lots more."
She raised her head and looked at him, wondering if by any chance her youngest brother was putting her on. "There is lots more," she said. "Back in castle torture chambers the execution girls were each given a prisoner. They could keep him alive an hour, or a day, but never more than a week. Their prisoner wasn't tied, just like you're not tied, except for this long braid of my hair around your ... your big hard penis. Didn't have to because all the prison guards were watching the fun. Only difference between you and those prisoners is your cock was hard when I braided the noose."
"What'd they do?" begged Dennis, visualizing himself in an ancient gray stone-walled dungeon with his gorgeous captor about to do something wonderfully-terribly final to him.
"Well ... what they did was to use their hair noose to make their penises bigger and bigger by tightening the noose on the base of the prick, suckin' them and liftin' them higher and still higher off their cots till it looked like their organs were going to fly right off their fronts."
"No kidding?"
"I'm not kidding. Here's how ..." She seized the braid of her hair close to where it wrapped round his prick and simultaneously spread her lush lips over the broad crimson glans, wringing a cry of delight from her brother as she closed her mouth with viselike determination around the protruding prick ledge.
The delight was mingled with fear a second later when her lips began siphoning and her hand tugged farther upward. Wild tremors rifled Denny's body as he felt vulnerability and lust at the same time. The feverish oral trap that had taken his cock-crown from sight had to be the most beautiful sex sensation he'd known in his inexperience, and the danger had to be the most real a deep animal instinct had ever warned him to run from.
"Oh, God ... Kitty! That's fantastic. What's happening?" His eyes wide and dilated with panic and passion, he stared at his organ buried in her mouth.
She released the tight grip on the braided hair and he sank to the mattress with a groan and moaned protest when she spewed his sopping erection from her mouth.
"What's happening, brother mine, is fellatio. It's what you'll probably like second-best to something else all your life. It's what the prisoners got for one day or one week with the hanging treatment till they had grown at least an inch from bein' dragged upward while they were being sucked. Then when it was longer and hungrier than ever, just when the enemy was shooting his love into the execution girl's mouth, she'd rip hard on the braid, or sometimes just use her clenched fist and tear it right off his front."
"Holy keesmash!" Denny's eyes registered pure horror at such a fate. "That's wild!" , "You'd never get by one suck, sir," Kitty announced as she studied a frenzied new burgeoning of shaft and cap. "You've already grown at least an inch."
His lower hp trembled from the conflict of fear and desire and she leaned to her target. "Thought this big prick could shoot without even being touched," she taunted. "It can't shoot even being woman-loved."
"Scared outta my skull," admitted Dennis.
"You should be. This could be your last shoot in all your life if you were in that prison dungeon. And you can't do anything to stop me."
Youthful imagination and frantic passion for her mouth on his organ overwhelmed any coherent words. He watched, electrified, as Kitty ovalled to his ballooning prick-tip even as she dragged on the braid again. He never noticed her free hand groping for the test tube under the cot.
Her siphoning was slow and demanding now and her tongue devilled in and around the hyper-sensitized ledge of the crown, bathing the tortured knob in a whirlpool of warm saliva as she milked mercilessly.
"Oh ... ahhh ... I'm gonna... yeah ... YEAH!"
Kitty took the barrage of young cum against the roof of her mouth and, at the height of his ejaculation, jerked the braid, snaring the base of his cock and ripping the prick from her lips. A gray-white stream looped into the air and she caught it artfully in the test tube, then, even as his cry of dismay stormed at her, she trapped the penis in her lips again, milking it through the rest of his climax.
"Sis ... oh, Kitty, that was too much ... gee, thank you, thank you."
She let the barely softened phallus slide from her oral trap, and felt the maddening need deep in her vagina begin to climb in that familiar way. It was barely a breath away from the moment of truth, Kitty knew, when, without any visible stimulation, she would do just as Denny had first done. Climax without anything but the fierce seduction of her senses and without any normal route to orgasm bringing her on.
"It couldn't have been that good for you," she whispered, tugging suggestively at die braid of hair still gripping the thickened horny shaft. "You didn't go down much."
"Do me again ... oh ... please, Kitty. Your mouth is so beautiful on him."
"Aren't you afraid?" she devilled. "This time might be the time I jerk the noose and send you to your reward without any plaything."
"I am afraid." His eyes fixed hers as he spoke. "I know you probably are makin' it up, but you could even be telling the truth and you might slip while I'm shooting and I'd be wiped out. Gosh, it's scary, but ... but do me again."
Kitty did. With eyes closed against the enflaming sight of her brother's face as the passion built, she munched and siphoned the phallus, drawing upward on the cock noose as she milked, and feeling his slim body arch more and more deeply in answer to the erotic pain of the pulling. Again, unnoticed, she slipped a test tube from the rack under the cot.
When his climax took him she was steeled against letting herself go, she thought, but suddenly, without warning, the spasms rolled in to claim her. Violent convulsions from a possessed and very empty vagina racked through her hips and -middle and sent uncontrollable shudders through her shoulders. She clung fiercely to the little glass in her hand and let the happy delirium of the spontaneous combustion wash through her.
"What happened?"
She shrugged and slid from the edge of the cot "Just say it's your sister acting the way the Carrs do. I had an orgasm."
"Wow! Girls get a lot more violent than guys, don't they?"
That remark broke the tension built up in Kitty around the desire for total lovemaking then and there. With a squeal of joy, she threw her arms around her brother and kissed him happily on the lips.
"Kitty, I can taste it. Did you swallow me after I shot?" His look was pure awe, "It was my Denny milkshake." She crinkled a disdainful nose at him, undoing her hair braid from his cock. "After all, it was mine to do with as I pleased, once you gave it away, right?"
"Yeah ... gee, you're something else!"
"So are you." She was on her knees beside the cot, lifting the two test tubes from the little wire rack and waggling them before him. "Men are supposed to squirt maybe a teaspoonful each orgasm and look at this."
"What about it?"
"It's about three tablespoonfuls each time." She pushed to her feet and hurried to the lab table to prepare three new test slides while her brother lay worshipfully watching the voluptuous near-nude poised at the edge of the stool, bent to the microscope. Dark hair tumbled loosely, obscuring her profile, but at the moment he wasn't interested in her face. Kitty's body had a peculiar light to it, a kind of a radiance to the ivory perfect flesh. The sleek contours of breasts and arms and thighs, the smooth plateau of her tummy, and the tantalizing shadow of her pubic hair concealing the mystery at her crotch all seemed accented by the glow he could see clearly. He wondered if all females shone like this when they were sexually excited.
That she was excited even while preoccupied with her slides was clear. He knew that much about girls, he thought quietly, studying the pointing cones of her nipples that appeared to stand in a sort of pink translucent readiness even as she worked.
Quietly, he slipped from the cot and moved noiselessly across the tile to stand behind her. She was concentrating on the glass, muttering something to herself and unaware that he was inches from nudging her spine with his newly refreshed hard-on.
"Fascinating," she murmured aloud suddenly, not looking up. "Your first ejaculation wasn't the highest motility of sperm; your second and third are much different. When you were scared a little and still had to do it."
"Go for four?" he whispered, leaning to peer over her shoulder.
"Go for four," she answered, not looking up and fighting for self-control at the feel of his knobby hugeness urgent against the thin nylon panties covering her buttocks. "Denny ..."
"I want to see," he interrupted, hands on her hips and pushing her to one side to take her place on the stool.
"Look. Here's the first." She shoved the slide onto the track and pointed out the mystery elements swimming so actively. "Enough to father a whole city in one discharge, if we knew how to save it all."
Her hand reached over his thigh as he crouched across the scope to look at the second exhibit. "I wonder if it could."
"What? Come again? Dunno. I've done it five times in one day, but never more'n two or three at one time."
"It'd take a super build-up, right?" She squeezed the jutting flesh and tugged to pull him from his preoccupation with the microscope. "It's time for the next stage, Dennis Carr."
As they walked across the room she fingered her bra snaps, and the cover literally sprang from her chest from the pressure of the liberated breasts. "You're going to get a special lesson in a woman's body," she said softly. "Would you like that?"
"Would I!" He dropped to the cot and flagged his cock bawdily at her as she stepped from her panties.
"Ladies first!" She caught his wrist and dragged him unceremoniously from the narrow cot, sending him sprawling on his back. She stepped across him haughtily with pretended contempt, then, standing astride his slim frame, she kicked at his erection with her bare foot.
Dennis could have cared less. He was being treated to a tantalizingly provocative display of a wonder-world he had yet to explore. The woman's center of sex play. Gaping up Kitty's sleekly tapered legs, he gawked at the meeting place of her gorgeous thighs. A dark cleft split the base of her prominent vee mound and he wanted to grab for the mystery.
Sensing his impatience, Kitty tumbled to her back on the cot as Denny scrambled back over the side. "Why don't you go discovering?" she urged, excitement tingling at every erogenous point as she felt his needy phallus.
"You're gonna think I'm silly, but can I do something?" '
"Sure, Denny . . . anything." She caught her breath and started to correct the invitation to "almost anything," then realized that was hardly necessary. Her baby brother, for all his overdeveloped equipment, knew nothing about intercourse and for her everything else with Dennis was permissible. "What do you want to do?"
"I want to study you real close. I mean, well, you know where."
The tremor traveled like a wriggling bolt of summer heat lightning. "Do whatever you want," she encouraged, in a voice low and sultry. "Why not start here?" She arched her shoulders against the mattress to thrust ripe, full breasts, hard-nippled with want for special attention. "Kiss me, Denny ... please!"
His lips, warm and moist, lingered on hers and she drove her tongue against his teeth, felt them spread and make room for the spearing dart to stab suggestively into his oral port.
"That's wild!" His cock, hot and urgent, was grinding against her calf as he took his turn at tongue-dueling.
Hard to believe he was only fourteen when his lips left hers and traveled downward, brushing warm lasses along the taper of her throat, across her shoulder and then diagonally to the waiting cherry at the center of the milk-white globe. When his mouth formed a tight oval at the nipple, a low moan burst uncontrollably from Kitty's lips.
"That is so nice!" She fought back tears of happiness mingling with lust for more, and then the lust was building in spite of her fright. "Denny," she panted as the nipple-love moved to the other breast and his hands became simultaneously involved in a light massage of the boobs.
"Denny, you aren't the only one with spontaneous combustion," she warned. "Curl your body so I can play with you while you do that ..." She stretched her arm as far as it could reach and couldn't quite touch the eager hardness grinding hotly against her knee.
"No way!" he whispered, and now he sounded less like an adolescent. "We haven't got any test tubes here and you know what you said ... get it in a glass."
She writhed under his mock accusation and felt her self-control slipping quickly as he continued to love her breasts. Erotic electricity darted to every corner of her body with each tongue-strumming of a nipple, and her hand crept across the trembling flat of her belly.
"What's that?" gasped Denny, twisting from his play with her boobs to stare at the palm cupped across her mons. "What are you doing?"
"Girls like to do it, too." She closed her thighs over the in-driven fingers, self-conscious at his stare at her masturbation. "Stop looking!"
"You wanted to look at me." He propped to an elbow and all she could see was the rumpled hair and the slender shoulder blades as he craned to watch her self-play. "It's beautiful . . . your fingers are way up inside your... your ... wow!"
Her body seethed in savage climax convulsions, hips writhing so feverishly that he was humped from his elbow and lay sprawled across her midriff as the wonder of her climax held him transfixed.
"Gee, you really blow your cool when you come, don't you?" he demanded, still lying across her middle and watching the curious spasms of after-orgasm travel lightly over the taut flesh of her tummy.
"It's the way every woman is," murmured Kitty, feeling the new lure of his eyes studying every muscle contraction and wanting him to study more. "You can look closer if you want."
"Gee ... thanks!" He wriggled across her legs and when urgent fingers pried at her thighs she let him spread them wide enough to permit his kneeling in between. The certainty that he was still erect had no place in her thoughts as he bent very close to stare at the pulsing pudendum and to finger tenderly at the folds of her cunty gates. It was a curiosity that shouldn't be suppressed, she reassured herself, remembering her own curiosity in graduate study was little more than an advanced state of the same interest.
"Can I put my finger through?" he whispered hoarsely.
"Gently." She urged upward slightly from the mattress to make it easy. "See the tinier folds of flesh just under the bigger slit? That's a woman's labia majora and labia minora ... and ..."
"Yeah ... yeah, I get it ... bigger opening and smaller opening, huh?" '
"Well, kind of." Her laugh was brittle with tension as his fingertip at that instant brushed her clitoris tip. "That! Right there ... know what that is?"
"Golly ... no."
"That's where most scientists believe a woman's most intense passion-feelings are centered. They say the clitoris is where the most satisfaction in orgasm is developed and even when she feels it to her tippy-toes, the clitoris is where it really peaks."
"This is the clitoris?"
"OOoohhh ... yes! Be careful!"
"But I thought a man was supposed to go way down a hole and all the girl did was take it and like it."
"That's ancient." Her eyes sparkled with the eagerness to clear a myth from her brother's mind. "There is a kind of "hole,' as you call it, but... here! You can touch." She caught the base of his hand and guided him away from the clit to the threshold to her vagina. "Just push one finger along into that place you can't see ... what do you feel?"
"It's warm and kinda wet-like and wow! It sorta grabs my finger." He kneed his way deeper into the valley of her legs, but she never noticed, as the fight against a surge of climax became almost overwhelming. "Thought you said the clitoris was where the feeling was." He gawked at the glazed stare fixed on her face.
"It ... really is ... it ... there's little sensory nerve endings in the vagina, too ... but the clit ... the clit ... Denneee! I'm going to have to come!" Her lower body was in wriggling surrender to the passion claiming every pore and nerve of her body from his finger stimulation. Eyes closed against the paroxysm of her orgasm, she didn't notice the change in her brother's body angle to hers.
At the first grab of her cunty walls against his deeply buried forefinger, Dennis had completed his sex education. He knew. Beyond a shadow of doubt, he knew that that was why cock had been put on a man. To go into this part of maddening woman-flesh. It was a savage, wonderful end to guess-work which shy Dennis never had dared ask either Barry or his father to tell him about. Now he knew, and as he deliberately simulated a tiny cock with his finger and listened to his sister's come cries, he knew he was ready.
Her eyes squeezed shut, her lips parted and her head thrown far back over the edge of the daybed, "Kitty was out of this world in a private joy orbit brought on by his finger strumming. He angled stiffly and awkwardly and gaped at the daring which aligned his rigid penis directly toward the quivering pussy slit. Pink and lovely, it was an open gate to cock-heaven! With a gasp he thrust forward at the instant he withdrew his finger and the conical tip of his prick disappeared like magic through welcoming cunty lips.
"Oh ... oh ... OH! Denn ... Dennis, you're fucking mel Oh, please ... don't!" She made an effort that was little more than a token resistance.
The arrogant cock stuffed urgently through the yielding folds of her passion flesh and the climax that had been rolling freely to his finger stimulation was now a cresting thunderous claim on every point of her ready body. His cry ricocheted from the walls of the room and his ejaculation battered angrily into the . waiting trap of her unfilled cunt. The climax had come too fast! The monstrous cock was only halfway into the convulsing vagina before her spasms against the in-driving hard-on had forced it to orgasm.
"Damn!" moaned Dennis, wrapping her tightly with his arms, lest she try to escape, then feeling her legs scissor snugly at his waist to let him have the message of her rapture. "Gosh, Kitty, I couldn't help myself. I just had to do it to you."
"We both had to," she murmured, nuzzling into the warmth under his chin and feeling the steel of his phallus softening. "Anyway, it's your way to learn and now I've taught you something, maybe." Somehow it made it feel all much more academic and almost as if it was right for it to have happened right in Merriweather Hospital's grad school quarters. Write it off to research, she tried to rationalize ... forget that she had led another brother to demand incest
"I didn't learn much," he mourned. " 'Cept how super it feels to be inside you and to feel you coming crazy like that. I should of made it go lots longer."
"We'll just call you 'preemie,' like they do in hospital nursery," giggled Kitty, wishing the slightly collapsed cock was roaring Hard and driving crazy wild into her ready quim again.
"What's preemie? You mean like premature?"
"What's premature for one man may be fine for another and we both loved it, right?"
"Still came too fast and, my gosh, after three other times. I'm really a freak!"
"Oh, brother-dear, you are a freak-a lovely, oversexed, sweet freak and don't you ever dare change." She squirmed under his body. "But we better break this up. Some people don't approve of it"
"Hah! I know that much anyhow. I read about all of it in Spanish history and in some older stuff, too. This is incest when it's doin' between two in the same family, isn't it? That's why old Miss Eldwood blushed when I asked her what that word meant."
"That's what it means. Lots of people who don't think they're ancients would really condemn us for being like this. And if we were doing it to have children, I'd condemn it myself."
"But we're not, right?" His eyes were wide with sudden uncertainty. "Gee, how do you tell?"
"You wear protection. I'll tell you how later. Anyway, I always have protection and I'll tell you about that sometime, if you want to know."
"Yeah ... I want to know everything." His eager young body was stiff and now it began to relax and mold against her succulent contours. "I can feel your nipples in my chest and it just feels like we're one body, not two."
"We really are one body, Denny. And we're getting more one all the time. I do not believe you! You're getting hard and huge inside me all over again."
"This time we take lotsa time ... oh, damn!" He ripped himself violently from her arms and left the cot on a dash to the lab counter for a test tube. "Remember ... gosh, my boss is forgetting!" His eyes danced. This time when I shoot I'm gonna get some of it into this."
That I've got to see." Kitty squirmed under his return, her appetite out of control at the sight of her naked brother's slim frame darting back from the lab counter, boasting a top-heavy prick, its bone-white barrel glistening with their mingled cum excitement.
"Gotta keep your legs apart, so's I can get free," he demanded when her thighs crept round his waist to seal his cock in her need-filled passion-sheath.
He ground slowly into the welcoming vagina, stuffing every quivering inch of his erection from sight and steeling himself against too quick a finish when the urge to pump frantically swept over him. This time he wanted to savor every woman wonder, to build both of them slowly and to become fully male and far more than a hand-led adolescent
"Denny, I don't think I can wait much longer." Her plea was music to his ears. It was declaration of his success as conqueror and lover and hungered-after male. "Please, Dennis, it's too beautiful ... I'm going ... I'm going to cuh... come!"
"Hang on. You're actin' like a preemie!" he taunted, letting the thrill of victory sweep through him and finding it something he could do if he braced muscles in his groin which he didn't even know about against the sweep of demand that he climax.
She was locked in end-over-end orgasm and he savored the full emotion that took her, letting the little screams she couldn't repress accent her seething surrender to his deeply buried prick. Abruptly the game was reversed and Denny's controls were blown to the commandeering of her vaginal muscles, clutching and snapping against his hardened tissue.
"Gotta, Kitty... I got to... to ... ahhh!"
He wrenched violently against her attempt to wrap him with those gorgeous legs and the effort reminded him of the test tube still clutched in his hand. With a grunting incoherent babbling he dragged his sopping cock from her frantic passion-maddened vagina and aimed the discharging organ at the test tube. One bolt missed, the next splashed squarely into the glass and he gave a hysterical cry of male-in-extremity as her fingers found and dragged his organ back to her demon-driven pussy-cleft
Their bodies cemented together in a mania of interrupted coitus begun-again and, as she took the full final blasts of his ejaculation, Kitty locked arms and legs around his body to claim every drop of his discharge.
In the room adjoining, Henderson Windham, M.D., stared through the see-through mirror from the concealment of the secret observation room he had put there when Room 5 was used in psychiatric programming at the grad school. He gaped at the unhinged passion on the daybed, possessed with a need to respond to the sight but driven by an all-consuming jealousy of Kitty's play partner.
"He's no more than a boy!" gasped Henderson, when the tousled head of Kitty's playmate lifted from its burrowing. "My God, it's her own brother!"
Dennis Carr had been frequently around the hospital corridors long before he had reached the admissible age for minors and more than once Windham had seen a nurse or attendant usher the eager youngster from the hospital corridors when he'd been too pushy in asking to be allowed to help around the place. "Lord, the size of him!"
The pendulous prick, its iron gone but its dimensions still impressive, slid wet and satisfied from Kitty's cunt. "Thanks ... gosh, thanks," muttered Dennis. "Here... here's your specimen."
He seemed suddenly self-conscious and, when there was no response from his sister, he slumped over the edge of the daybed and sat disconsolate beside her, feeling the cool linoleum against his tail in sharp contrast to the heat he had just known in their embrace.
"I'm terrible," murmured Kitty. That could be habit-forming and it's only for education. You understood that, didn't you?"
The listening Henderson felt his heart pound furiously against his chest and what he had braced himself against doing when he first slipped into the hidden room to spy, now commandeered all common sense. He pounded his erection mercilessly as he stared at the nudity spread on the cot; all the female wealth in the world seemed housed in that wanton voluptuous body. Thoughts of her incest with her brother were a million miles from Henderson's longing to be where Dennis had just vacated. He gaped at the sight Kitty had the leg farthest from his viewing bent and the other outstretched, offering a full view of her still parted quim lips.
"Little bastard bruised her!" muttered Hen, gawking at the puffy slit and noting the reddened pussy tissue. The cunt lips were puckered in a delightfully inflaming invitation to mayhem and the long-denied Henderson Windham wanted to burst through the separating glass to get at the girl. If she had to turn to her baby brother for sexual satisfaction, she was as frustrated as he, even if in a different way. He had sensed it when she posed for his effort to give her a sampling of his masturbated best, and he'd known it by the convulsive grinding of her hips against the examining table when he was coming into her lips. That she would go all the way hadn't occurred to him seriously. And now it had been demonstrated. By her own brother.
"Baby doll, you're going to meet a man-damned soon!" gagged Henderson seconds later when his orgasm had passed. "Son of a bitch! I'm worse than the kid!"
His eyes caught the line-up of test tubes on Kitty's counter rack. He moved behind the wall mirror, confident that he was invisible from the lab side and grateful for her rearranging the lab furniture to place her work counter so close to the see-through glass. He could enjoy the total room from his hiding place, and when she was at the examining table or the work counter staring into her microscope, he was less than two feet away.
"Number one specimen. Hummmhh, that's me," he speculated aloud, knowing that, while he could hear from the lab, they could not hear him. "She was studying my semen when the boy showed. God, four test tubes. The little bastard fired four times for her and I'm the dull shit who told her to get a young man in for her study. She's gotta be hooked!"
"Hooked" was a fairly accurate word for the feeling riddling every sensitized nerve of Kitty's body as she dragged the formless lab smock over her nakedness. Her thoughts tumbled from Dennis to Barry and back again. All unexpected, she insisted to herself, was the copulation with Denny. She had no deceit inside about the hand-play, and the oral play was understandable. But not the fornication. It had simply come and again it was Denny who, for all his innocence, had started it. How beautiful and how wrong, her emotions screamed. Yet quietly, overriding the sense of guilt, there was a new intense curiosity inside her discontented body. For no understandable reason, the image of her father, Stewart Carr, was vivid before her eyes as she settled down on the lab stool. Stewart Carr, the only male in her immediate family she hadn't been intimate with. The one man in her life she had always wanted to lock into her bed.
"Anything I can do, sis?" inquired the fully dressed Dennis, standing at her elbow.
"Just one thing. No bad feelings. Nothing but happy feelings, right?" She smiled into his eyes. "You've made your sister a very happy woman, and if you want to quit working for her down here, you do it."
"You kidding?" He grabbed the broom. "I haven't done a lick of work and you're firing me."
The listening Henderson Windham began to add it all up. She had brought her kid brother onto the scene to be the youthful experiment Windham himself had recommended. To cover it at home she was making him her clean-up odd-job boy. Clever.
"Denny, you're amazing!" Kitty looked up from her scrutiny of the slide specimen of his final ejaculation. "You wouldn't believe it, but there's so much motility in your last discharge you can hardly tell it from the others. It's down a little, but not much."
"Horny little shit!" grunted Henderson enviously, as he turned away from the sight of the intriguing grad student, vainly trying to conceal her sensual impact by fastening her smock closed with the ridiculous giant clip. He had a board of directors' meeting in five minutes and only that could tear him from remaining at his voyeur post for the afternoon.
Scheming about ways to get back to Room 5 by the next day, Hen Windham hummed quietly to himself as he headed for the board room. In spite of her loose morality, he had the strange feeling she could possess any man she wanted at the snap of her fingers. Inside, he knew she had already possessed nearly every waking thought one Director of Grad Studies was to have for a long time to come.
