Chapter 1
Kate Ryan didn't know what to think as she stood there and spied on her son. She was well aware that Larry was a senior in high school, with the kinds of things boys had on their minds at that age. But it was the first time she'd ever faced it in such an extremely personal way.
Kate sensed that perhaps the best thing for her to do would just be to go on about her business and pretend she hadn't seen this. After all, Larry wasn't hurting anyone and he was certainly entitled to his privacy. But the fact was that Kate didn't budge, almost hypnotized by what she saw her son doing to himself.
"I-I didn't have any idea he was so ... so big down there," she whispered to herself, while watching his hand rhythmically stroke the long, thick, throbbing object of her fascination.
"Mmmmm, feels so damned good," the boy moaned, totally unaware that he had his mother as an audience.
Larry Ryan's right hand now picked up the pace, moving faster up and down. His face turned red and he was almost breathless. Then, with a long, husky sigh he'd reached the peak of his pleasure. A creamy jet spurted from the part of his body he'd stroked to this intense moment, then splattered in sticky globs between his quivering thighs as he sprawled naked on his creaking bed.
"He's such a beautiful boy," Kate Ryan murmured.
Then, at last, she was able to force herself away from the partially open door Without having been noticed. But from that point on Kate couldn't forget what she'd seen. The sight of her teenage son jacking off his hard, young cock had definitely left its mark.
"I know what I saw Larry doing to himself is the kind of thing a woman should talk to her husband about," Kate admitted. "But the truth is, I've never been comfortable at all with Clint when it comes to this. You know ... well ... sex."
"Christ, Kate, you and Clint have two kids together. Now don't tell me that sex didn't have anything to do with that."
"I know, Jim, I know," Kate sheepishly sighed. "But that was something Clint and I just did. I was just doing my duty as a wife, no questions asked. But when it comes to talking about sex, you're the only one I can trust, Jim. You're not just my brother—you're a doctor."
Kate's brother took a deep breath before asking a delicate question. "Okay, Sis, I'll try to help. But first I have to know something to help me get a fix on where you're at. Sis, pardon me for being this blunt—but are you frigid?"
Kate flinched, but realized she had to be honest. "If you mean do I have orgasms when I do it with Clint—no, Jim, I'm afraid not."
Her brother responded by gently coaxing, "Sis, it'll loosen you up if you say exactly what you mean. 'Orgasm' is a word out of books. 'Doing it' is what school children giggle about. We're both adults, Kate. Lay it on the line to me."
Kate flinched again, but she managed to tell her brother what he wanted to hear. "Okay, Jim, here it is, then ... When Clint f-fucks me, I don't c-come."
Taking advantage of the breakthrough like the skilled doctor he was, Jim quickly quizzed, "Have you ever come at all, Sis?"
Kate shook her head, murmuring, "Not that I know of."
"Then not even when you've played with your own pussy, Sis?" Jim frankly yet soothingly inquired.
"I-I've never really done that either," Kate stammered. "Well, maybe a little touching when I was growing up ... but nothing ever serious."
Jim shrugged and replied, "Well, there's your problem, Sis. Of course seeing your son giving his cock a hand-job has you upset when you've never done the same kind of thing to your own pussy. Believe me, Kate, it's as normal as apple pie on both sides of the fence. You should really do yourself a favor and try it."
Kate was both stunned and fascinated by her brother's suggestion. "I knew that boys did that, but not girls—"
"Not just boys and girls, Sis," Jim cut in. "Men and women, too. You're never too old to make yourself come. In fact, I often recommend it to my patients to get in touch with themselves when they're having trouble with their partners in bed."
"I'm not sure I'd even know how to start," Kate gulped.
"Just trust me and take off your clothes," Jim patiently answered. "You won't regret it, Sis, I promise you."
"Me naked ... in front of you?" Kate gulped again, much harder. "Jim, you're my own brother!"
"But I'm also the doctor," Jim reminded her. "Doctor's orders, Mrs. Ryan."
Kate squirmed, but then decided to go through with it. She was so nervous, though, as her trembling hands clumsily fumbled with her skirt.
"Here, let me, Sis," Jim finally offered. He got up from his chair and walked around the desk to stand over his anxious sister. Taking her hands, he drew her to her feet. Then his own steady hands did the job at her waist so her skirt slid to the floor. Underneath she wore a garter belt, sheer stockings, and bikini panties which were normally pale blue but had been freshly stained to a much darker hue at the crotch.
"See, Sis," Jim chuckled, "you're already raring to go. Just look at those panties."
Kate glanced down at the telltale stain at the crux of her quivering thighs and self-consciously blushed. Her cunt, without her having been aware of it until just now, had long since
become sopping wet as a result of her conversation with her brother.
"Now let's get these off and get to the, uh, source of your problem," Jim whispered most persuasively, his doctor's experience at stripping female patients expertly displayed.
Closing her eyes and holding her breath, Kate allowed him to peel away her damp panties, leaving her naked from the waist down. Then she felt a warm breeze caressing her bare crotch. When she opened her eyes again and looked down, her brother had knelt before her. His face was just inches from her cunt, as he inspected the most private part of her body with a doctor's professional gaze.
"You have a beautiful pussy, Sis," Jim said without hesitation. "For a woman with such a beautiful pussy to be frigid is a real crime. I wouldn't be doing my job as a doctor if I didn't do everything I could to teach you how to come."
"Yes, Jim, teach me ... teach me," Kate panted, letting herself go. "I want to learn bow to come so bad."
"Then put your hand down there, Sis," Jim prompted. "At the top of your cunt, where the lips grow together. Find your clit and start rubbing it."
Kate fumbled at the fleshy summit of her pussy. Obviously, from her awkward performance, she had spent her life only being halfway aware that she even owned such a thing as a clit.
"I-I don't think I can find it," she choked. "Maybe I don't have one and that's why I can't come."
Jim not only knew what he had to do, he welcomed the opportunity. "Here, sis, let me show you."
Now his hand was at the top of her cunt, his thumb and. finger expertly spreading the delicate cluster of pink there. He smiled when he viewed the result close-up.
"I still can't see it. Is it there, Jim? If only you could make me feel that it's there where it's supposed to be."
"Really want me to, Sis?" Jim asked, his breath getting ragged. "This is something a doctor only does- when be has a patient's permission."
"Oh, yes, Jim, do it to me. Make me feel my clit the best way you can. A doctor must have some kind of gadget for that, to help somebody who's frigid finally feel like a real woman."
Indeed, Jim did have the device guaranteed to bring his sister's long neglected clit to her heart-stopping attention. But it wasn't something which only doctors used. For, regardless of his profession, no normal man when facing a cunt as eager for release as Kate's could have resisted leading with his tongue.
She responded with electric immediacy. "Oh, Jim, lick it, keep licking me like that! Lick my clit! If I don't come from this, I never Will!"
With a doctor's knowledge of the female body, Jim skillfully lapped Kate's magic button. Nor hips had started to roll. A constant moan bubbled on her lips.
"Oooooh, after all these years, I'm almost there. Almost ready to come at last!" she swooned. "Just show me what else I have to do to make it finally happen, Jim. You're the, mmmm, doctor "
While he continued to orally massage her clit, Jim reached for one of his sister's hands. He guided it between her legs, making Kate rub her own hairy crotch. Then she instinctively knew what to do next, probing her cunt gash and beginning to finger-fuck herself as deeply as possible while Jim licked above.
"Ooooh ... ahhhh ... mmmm, it's gonna happen!" Kate declared. "I ... I'm commming, now, now, now!!"
Never had a female body reacted to a climax with more intensity. Kate was orgasmically writhing on her feet. Then they gave way beneath her and she slumped to the floor. Her brother immediately swiveled around on top of her when she'd landed, straddling her head. When she looked up his bulging crotch was in her face, just waiting for her to unzip it and get at his obviously rigid cock.
"I'll never forgive myself if I don't do it," she breathlessly told herself.
She eagerly jerked open her brother's pants. He wore expensive designer underwear that clung to his cock and balls like a second skin. She hooked a finger under the elastic, pulled it to one side, and all of a sudden she had a faceful of a pulsating hard-on.
"Sooooo big. As big as Larry's," Kate said, homily comparing her brother's long, thick rod with her son's. "God, I've just got to suck it. Suck your huge cock, Jim, until it comes in my mouth -so I can swallow every drop of- your hot, sweet jizz."
Her lips then clasped the chunky head of her brother's stiff prick and began gradually slurping down the heavily veined shaft. Jim responded by bucking his crotch. The next thing Kate knew she was deep-throating him to his balls and he was fucking her cunt of a mouth.
Oh, Kate thought, sucking her brother's cock made her feel as if she had two clits now—one down at her pussy and the other one in her throat. After a lifetime of being frigid she now felt as if she were climaxing two ways at once— twice as hard as a normal woman.
However, beyond her own orgasmic thrills, what Kate craved most of all was her brother's climax. She was so thirsty for his jizz that her stomach rumbled in anticipation. To get it, she increased her suction on his mouth-fucking cock and squeezed his baby balls.
For his part, Jim was quickly well aware of what his sister wanted. And he was more primed to give it to her than to anybody who'd ever sucked his cock. For the fact was, he'd been hot for Kate ever since they'd been growing up together in the same house as children. As a teenager there'd been many a time when he'd jacked off over her after glimpsing her coming and going from the shower. And now, at long last ...
"Ooooh, this is it," he groaned into the hairy nest of her cunt. "God, I've waited so long for this without ever believing it'd finally happen!"
And Jim's thoroughly sucked prick erupted in Kate's deep-throated oral grasp. As he shot his creamy wad, she came every bit as hard as he did. As his mouth sealed her climaxing cunt, she oozed almost as much orgasmic pussy juice over the tingling taste buds of his swabbing tongue as his cock poured scalding jizz straight to her belly.
Neither brother nor sister could seem to get enough of the other's delicious flow. Even after his cock and her cock slowed to a dribble they nursed between one another's legs for every extra drop of cum they could get. And the more they got, the hornier they both became for the next logical stage of the action. The only thing that could top such a sensational sixty-nine. For even better than sucking was, of course, cock and cunt one-on-one fucking!
"Yes! Yes! Yes!" Kate now declared, finally releasing hem brother's prick when she was sure she'd kept it hard. "I know you want it as much as I do, Jim. I can read your mind, just like I'll bet anything you can read mine—the way only a brother and sister can."
"You mean?" Jim anxiously asked. "You're sure, Sis?"
Kate said it loud and clear. "Fuck me, Jim! Fuck my cunt with your big cock until we both come so much we can't stand bow good it is!"
"And I thought I might have to rape you, Sis," Jim nervously joked.
"Works both ways, kiddo," Kate kidded back. "No way I'd, leave this office without getting your beautiful cock up to your balls in my hairy pussy!"
"Show me how much you want it then, Sis!"
Jim gusted, easing up on top of her. She rolled out from beneath him, turning herself into a centerfold come to life. With her knees raised and yawning to showcase her female essence between her thighs, she was suddenly virtually all cunt. What a cunt! With the outer and inner lips stretched apart, the pink tunnel within seemed to provide a direct route to her very soul.
"Oh, Jim," Kate sighed, "spreading my legs for you makes me feel like I'm cherry all over again. And I really am in a way, because no cock in my cunt has ever made me come before. You'll be my first real fuck in the way it really counts the most."
"You got it, Sis," vowed Jim. "Every inch I have to give. I'll fuck you the way you deserve to be fucked. It's about time you got a prick in your pussy that makes you come. Sorry you had to wait so long for the real thing—but, damn, am I glad to get to be the one who finally turned you into a real woman!"
"God, I've never been so ready for anything in my life!" Kate cried, reaching down to finger her pussy lips apart even farther, presenting the most inviting possible target for her brother's jutting prick.
Jim closed in on her for the erotic version of the kill. His hips slurped between her hoisted thighs. His cock was in his grasp like a weapon. He set his loins and took the plunge, stabbing with every ounce of his strength as though he were trying to split his sister in half as much as fucking her.
"Oooooh," she yelped with joy, "rip me, rip me! Rip my cunt to pieces with your big, fucking cock, you stud bastard!"
Jim poured it on for several nonstop minutes. If his sister had been all cunt when she spread her legs for him now, that be was fucking her he was all cock. And, going along with this incredibly macho sensation, his mounting supply of jizz felt like an inner ocean that was primed to launch a creamy tidal wave.
"Damn, Sis, I've never fucked a cunt that had me ready to come this hard," Jim panted. "How soon do you want my jizz, Kate?"
"As soon as I can get it! God, my pussy's so thirsty for your cum, Jim. The second it's shooting from your cock into me I know I'll be coming right along with you."
"Then now's the time, Sis. I couldn't hold back if my life depended on it."
That said, Jim thrust his cock to the absolute depths of his sister's cunt, his balls wedged between her asscheeks. And then, after a flexing lurch, the ten-inch volcano of his hilted cock erupted with molten cum.
"It's like fire!" cried Kate. "Liquid fire! Cum's burning up my pussy! God, it burns soooo gooooood!"
"But are you coming, Sis?"
And Kate abruptly laughed out loud. "My God, isn't it incredible," she mocked herself. "After all these years of being frigid, I just took it for granted when you made me come along with you. Oh, Jim, you're spoiling me rotten already. I can't imagine ever getting fucked again without coming like this."
"Then you-think Clint can do the job now?"
With his mention of her husband Kate scoffed, "Him? That loser? Are you kidding? Now I know I wasn't the one who's fault it was. It's Clint. His cock's like a piece of ice in my pussy. I'll never let that clown fucking again. From now on, Jim, it's just you and me."
Kate thought this was what her brother wanted to bear. But, as his dripping cock slipped out of her jizz-soaked cunt, Jim began hemming and hawing.
"Something wrong, Jim?" Kate anxiously asked him when she noticed how ill at ease he'd become.
Jim took a deep breath to brace himself before saying, "Sis, I don't want to hurt you, but what I did today—well, I was trying to help you. As your doctor, not just your brother."
Kate got the message. "Then I'm not the only one of your patients you've fucked?"
"You'd be surprised how many frigid women need help."
"Then you were just doing your job, that's all?" Kate muttered, abruptly feeling hollow inside after having been so full of cock and cum.
"Sis, I love my work. But I can't let it take over the rest of my life," Jim said. "Now that you're cured, go home and enjoy it. That's what'll make us both happiest, believe me. Just fuck Clint the way you did me and nobody'll have a better marriage than you two."
"Then," Kate gulped, "this'll never happen between us again? This is the first and last time you'll ever fuck me?!"
"Let's just say that you owe it to yourself to try and square it with Clint, Sis."
"He's hopeless," Kate insisted.
"You've got to give him a chance," Jim insisted in reply "Trust me, Sis. If I hadn't thought you could make it right with your husband, I'd have never fucked you in the first place. I'm just trying to be the best doctor I can."
"Sounds like a cop-out to me," Kate sneered, reaching for her skirt and panties. "I think you're just after all the pussy you can fuck and being a doctor is just an excuse to get it with no strings attached. It'd serve you right if all of us easy lays really were happy getting it on with our husbands."
"Then teach me a lesson, Sis," Jim countered. "Prove to me that Clint can fuck you just as well as I can."
"Damn you bastard! You're really making me want to show I can do it," Kate sighed.
"Then the treatment is a success," Jim hopefully said. On your way now, Sis! When Clint gets home tonight, show him the new you. Be with him the way you were with me. You won't regret it."
Kate reluctantly agreed. So she dressed and left her brother's office, on her way back to her family. Then, in the elevator, Kate realized that Jim had finished fucking her before he'd ever seen her tits. Now they were tingling with frustration and so she rubbed them through her blouse and bra, wondering if Clint would suck them when he got home tonight. Maybe she'd even coax his cock between them and tit-fuck him so his cum spurted in her face.
"Well," she sighed, lightly pinching her nipples and feeling it down in her cunt, "at least I'm half way horny for Clint for a change. Guess Jim is right. If he can get me even this hot for my own husband then he's some kinda doctor."
Back in his office, though, Jim was downcast. For in sending his sister back to her husband, he'd given her a bill of goods. The fact was that he'd never fucked one of his patients before. But it was a lie he'd bad to tell Kate to protect himself.
"I can't," Jim said trying to convince himself, "let Kate take over my life. I've to too much to lose to risk getting in too deep with my own sister. Sure, I always wanted to fuck her but once is enough— no matter how great a piece of ass she is."
Then Jim canceled the rest his appointments for the afternoon and went out to try and forget what had happened with Kate. But the call girl who got his hundred bucks, although she was a knockout, couldn't get it up for him no matter how she tried to earn her money and Jim strained. Even a luscious pro didn't have a pussy that compared to his sister's incestuous cunt.
"Goddamn it," he muttered when he left the call girl's apartment in total frustration. "I'm hooked, hooked on my own sister. Jesus, I hope I was wrong and Clint doesn't do it for her the way I can."
