"What are you doing?!" Jamie repeated, taking a couple of steps forward. Her eyes looked as if they were ready to pop out.
Robin pushed at Sean's chest and he slid off her, his prick jumping free of her tight slit. He rolled onto his back beside her, both of them staring at his sister in the doorway.
Jamie looked at Robin's flushed face and at her brother's stiff rod. Both of them were naked and sweating. She knew damned well what they'd been doing, but somehow she couldn't quite believe it. Her shy brother? "You were screwing!" she accused, the tone challenging them to attempt a denial.
There was no answer. "Well?" she insisted. "Weren't you?" Her fingers pulled unconsciously at the locks of auburn hair that streamed below her shoulders.
"Yes," Robin said resignedly. "That's what we were doing."
Jamie stared at Robin's lush body, not without a twinge of envious resentment. The older girl was like a blonde cat. Sleek, shiny hair, wide cheekbones, green eyes that tended to slant, a small chin set beneath sassy lips, wide and thin. And her figure, Robin's tits were plump and round, capped with dark nipples that looked like candy kisses on the cream of her boobs. So much better developed than Jamie's little titties. Envy mingled with admiration when Jamie studied the babysitter's cunt bush, a clump of curly gold that had been pressed flat beneath the pistoning weight of Sean's body, but a thick patch of pussy moss all the same.
And then her eyes fell upon Sean, lying naked, red-faced, beside Robin, his cock sticking up. He seemed too preoccupied with fright to worry about covering his hard on. Jamie hadn't seen her brother's dick in a long, long time, oh, except for the trouser bulges she'd noticed from time to time but even the dirty pictures she'd copped from his room hadn't quite prepared her for the sheer physical power that seemed to radiate out of the reddened cock sticking up from his wiry crotch fuzz.
There were butterflies in Jamie's stomach as she made herself understand that her brother had been fucking Robin, just like the people did in his sex pictures. That he'd been lying atop the blonde babysitter, ramming his cock into her cunt. That if she hadn't heard the noise and come to investigate, they'd have kept on fucking till both of them climaxed, till Robin squealed with her come and Sean filled her slit with his jism.
"So," she gloated. "Well, don't let me interrupt. Go on." Someone else seemed to be speaking through Jamie's voice, and there was a wicked insistence in her words.
Sean's eyes rolled helplessly and his cock began to soften. Robin slid to the edge of the bed, her feet dropping over the side. "Not on your Goddamned life!" she snapped. "I'm going downstairs to sleep on the couch. By myself!"
Jamie's lips twisted into a smile and her words were dripping with saccharin. "If you don't," she smirked, "I'll tell on you." There! She'd done it! What would they say to that? Besides, she'd looked at the photographs for so long, and now she had the chance to see a real fuck happening right before her eyes.
Jamie noticed that poor Sean's cock had shrunken and wilted now, just a little worm dangling from his crotch. He had to be scared. This was a lot more fun than teasing him with panty glimpses, Jamie decided.
Robin frowned. Bitch was too nice a word for this teeny aunt! And look at Sean! His hands were shaking and his prick had shriveled up pathetically. The poor kid was so scared he might never be able to get a hard on again, and that was too bad. He'd been improving by the minute, and now his sexual future hung in jeopardy.
Robin lifted her legs and lay flat out once more, her hand drifting down across Sean's belly. "I don't think we have any choice," she commiserated. Her hand encircled his prick. Two deft pulls, one squeeze, and his rod was hot and hard in her grip. Robin smiled encouragingly and parted her legs.
Sean looked at his sister, trying to read the blankness of her face. She had pulled the chair from his desk, removing Robin's piled clothing, and now she sat beside the bed, hands resting on her knees, lips curled into a terrifying smile.
"Come on," Robin invited, and the boy got between her legs once again. His prick was good and hard but his muscles had turned to water. Robin smiled cheerfully and she took hold of his dick, guiding it to the wet hole of her cunt. When the contact was made, she lifted her hips, engulfing his cock to the balls. His crotch bumped hers and their pubic hairs mingled. She moved her ass in a special way and he felt the clever tug of her cunt muscles on his prickshaft.
It was all the assistance Sean needed. He tried not to see Jamie's eagle eyed stare and he began to fuck Robin with all the passion that raged in him.
Jamie watched in fascination, moving her head this way and that to catch every aspect of the fuck scene before her. She had never guessed how beautiful the act of screwing really was. The pictures in Sean's books were nothing compared to what she was seeing now. There was a kind of grandeur in the steady drive of her brother's prick and a nobility in the way Robin's cunt sucked it home on each downstroke. And as she watched, Sean lowered his head a bit to suck at the stiff tips of Robin's boobs. The babysitter smiled with pleasure as the boy licked her nipples, and Jamie knew then that she wasn't the only girl in the world whose tits were so sensitive the slightest touch sent tingles rushing through her system.
Then Sean raised his head and his mouth met Robin's, just like actors kissing in a movie. It was so romantic, so lovely! Jamie's hand moved automatically, coming to rest upon her titties where they throbbed behind the loose fitting nightshirt.
Her eyes were transfixed by the image of Sean's ass lifting up and dropping down as he buried his cock again and again in Robin's cunt. She could bear the rustling of their crotch hairs, the swishing of Sean's prick as it moved between the juicy wet lips of Robin's cunt, and she felt her nipples grow stiffer, ever stiffer. They were making it together, her brother and her babysitter, fucking for their own benefit now, just as if she wasn't even there watching them screw. That made Jamie feel the strangest jealousy, as though she were being left out of a playtime game, and she wondered why she felt that way.
Sean gave a curious little choked grunt right into Robin's open mouth and he shoved his body hard against the babysitter's. His hips shook and quivered and somehow Jamie knew that her brother was coming. Robin moaned in delight, tangling her legs among his, and her fingers combed Sean's hair as he kissed her mouth and filled her cunt with his hot jizz.
"Wow!" Jamie whistled when the two of them had separated once again and were lying side by side. Sean's prick was limp again, and he was breathing heavily, sweat bubbling on his forehead.
Jamie leaned in close, scanning the wet, reddened slash in Robin's cunt mound. Sean's cum was dribbling out of the blonde babysitter's gash in viscous bubbly drops, some of it sticking in the girl's golden pussy curls, some oozing onto the sheet beneath.
Curiously, Jamie's finger darted out, scooping a gob of Sean juice from Robin's tender cuntlips. "Ouch!" Robin yelled as the younger girl's nail scraped the delicate flans of her twat.
"I'm sorry," Jamie apologized with due sincerity. "I just wanted to see." She turned the cummy finger before her eyes, studying it from a dozen angles. Sean's fuck juice was warm and sticky, oozing around like mercury on her fingertip. She'd only seen cum in his magazines and pictures – never the real stuff. When she came, she didn't squirt out cream like this. Another of the differences between boys and girls?
She remembered Oral Orgy, the centerspread shot, with the jism-drenched redhead. Cum squirting into the girl's mouth. "Is this poison?" she asked suddenly.
"Of course not," Robin sighed, still high from her own little orgasm. "Some people even say it's nutritious."
Jamie held the finger closer to her lips. She hesitated a moment and then her tongue shot out, licking away the sperm sample. She puzzled over the taste for another moment, then flashed bright eyes towards the couple on the bed. "It tastes good!" she said happily. "Sweet, and salty, and creamy, all at the same time."
Robin nodded. "I could have told you that. Now, if you don't need any more cheap kicks."
"Was it fun?" Jamie cut in. "I mean, did you like it?" Sean nodded quickly, a definite yes. "How about you?" she asked Robin. "Didn't it – didn't it hurt? Just a little bit?" The young girl was still unable to conjecture how an object as large as Sean's cock might fit comfortably inside a female body.
"No, it didn't," Robin said wearily. "It felt good and it didn't hurt at all. It's not supposed to."
Jamie weighed that for a moment. "Do you think I'd like it?"
"Probably," Robin nodded. "All girls like it, even if they lie afterwards and say they didn't."
Jamie pursed her lips and thought hard. At last she raised her head. "I want to try," she said. "Right now."
Sean looked at his sister unbelievingly, drinking in the plump thrust of her little titties, the lep bared to the thighs where her nightshirt rode high. What was he thinking about? Jamie wondered. About all the times he'd sneaked around to spy on her growing body? About the carelessness with which she sometimes displayed herself? The way she seemed to offer him a peek of her crotch now and then? His nudity left no hiding place for the interest which seemed to pulsate into his cock then as it stiffened afresh after two successive orgasms.
Robin saw his dick hardening and she saw that Jamie noticed, too. "It's none of my business," she conceded, "if both of you want to screw. I'm not going to stop you." She got off the bed and leaned her ass on Sean's desk, arms folded across her belly.
Jamie stood up. "I guess I should undress, huh?" she asked Robin, who nodded condescendingly. The young girl was flush-faced and her lips fluttered with her excited breathing. Impulsively she reached for the hem of her nightshirt, yanking it up and off so quickly Sean didn't have time to appreciate the fact that it was all she wore. Her brother's eyes caught the flash of the jerking garment and then she was beside him on the bed, pink and naked, her titties big-nippled, her cunny barely fuzzed at all.
She looked at him hesitantly, wondering if she'd gone too far, but by then he was upon her, fighting her leg open with his knees, fingers guiding his cock directly towards the frightened pink slice of her pussy. It was like a mad, desperate rape attempt, and Jamie screamed "NO!" at the top of her lungs, squirming in panic, slapping and pushing at her brother. Robin hurried to the bedside, plopping down upon the chair Jamie had abandoned.
"Take it easy," she cautioned Sean. "You don't just pile onto a girl and sock it to her. Not all the time, anyway." Sean drew back with a blush. "Are you a virgin?" she asked Jamie. "Do you still have your cherry?"
Jamie nodded. She'd forgotten all about her hymen! How could she endure letting Sean fuck her? His cock would touch her, membrane and, oh, God! Her protective hand closed over her young snatch and she cupped the plump bulge fearfully, hardly noticing the warmth and moisture that filled her palm. "Now I'm afraid," she said. "I know it's gonna hurt!"
Robin shook her head. "You might bleed a llttle," she acknowledged, "but there doesn't have to be any pain. Not if you're in the mood to be fucked. When I lost my cherry, I was having too much fun to notice."
Jamie's face was thoughtful. "Honest?" she queried.
Kids! Robin thought. She hunted around the bed till she found her cast-off panties. They were as good as anything else, and so old she didn't care what happened to them. She put them beneath Jamie's ass where they could catch any dripping trickle of cherry blood. "Okay," she said. "If you really want to do it, you should start off slow and easy. Sean, why don't you kiss her and feel her, the way you did with me? That's very relaxing."
"Kiss her?" Sean asked, staring goggle-eyed at his sister's beaming face. "Like we did?"
Robin nodded. "And feel her up, too. It might help if you touched him back, Jamie. Get comfortable with each other. Like that, but you can do better, if you're serious about this."
She eased her ass on the chair and watched the Willis children taking the first steps toward their incestuous sexual union. Sean kissed his sister, a little pecking touch on the lips, bath of them nervous and more than slightly embarrassed. The second time he smacked her, Jamie caught him by the head and held him tightly against her mouth, her own lips slipping open just enough to let some of her saliva flow into his. Sean perked at that and he pressed his sister down upon the bed, still kissing, still drinking her spit, his hands dropping down to test the firmness of her bare titties.
He caught a pink nipple between two fingers and squeezed it until his sister wiggled in delight, and then his hand skidded lower, tickling its way across the smoothness of her tummy, onto the rising plain of her cunt mound.
Like most brothers and sisters, they were not used to touching one another intimately, and Sean had several false starts before he actually dared to finger the tender lips of his young sister's pussy. She moaned deliriously when his fingers made contact with her gash, and her own hand seized his stiff, aching pecker, shucking up and down its rigid length in a skillful jacking fashion that came to her instinctively.
Sean was lost in the wet clutch of her mouth. He felt her tongue snake across his as they dueled back and forth, and Jamie's hot little fist wrapped around his cock was almost too much for him. Robin started as she saw him shudder and she was certain that he would geyser an arc of cum from his overheated young dick at any moment. She wanted to help him, but she didn't know how. It was his cock, his libido…
Sean got himself under control, relaxing his muscles, and Robin sighed in relief. Sean's fingers parted the tight mouth of his sister's rosy little cunt and they slipped inside, seeking her clitoris.
Jamie knew it as soon as he'd found her love trigger. A warm ripple of feeling sped through her body and she held his cock in a tighter, friendlier grip. One of his fingers touched the mouth of her cunt, poking at the tiny flanged lips, moving between them through the incredible tightness of his sister's twat until he bumped squarely against the cherry blossom that obstructed her passageway.
Jamie screamed at that touch, and her head seemed to explode in a burst of sounds and colors. Her ass bucked away from him and pulled frantically until all his fingers had slid free of her virgin cunt and her lips were no longer brushing his. Her hand still clutched his dick and she seemed torn between emotions.
"No," she said in a whisper. "I don't think I can go through with it. It hurt so much when you had your finger in me. How am I ever gonna be able to take this?" and she squeezed his peter to make her point.
Crestfallen, Sean looked to Robin for advice. The older girl sat shaking her head. It was too bad they'd both been determined to lose their cherries the same night. Jamie needed an experienced guy, one who could educate her to fucking the way Robin had done with her brother.
Robin scooted her chair closer to the bed, raising her knees and giving Jamie a spread view of the blonde-furred crack between the babysitter's thighs. "Look," she said, pointing to her open cunt. "You have a certain elasticity here. See my cunt? Touch it. Yeah. Put your finger inside it, not so deep! Your nails are too long. There. See what I mean? See how tight my snatch is?"
Jamie nodded, all eyes. Robin's cunt was just as tight as her own, or so it seemed. The younger girl could put the tips of her two smallest fingers inside the snug hole but no more than those two, for she was afraid of injuring Robin.
Robin's eyes swam as she felt Jamie testing her pussy. Cunt juice bubbled deep inside her twat and her clit throbbed suddenly. Shaking her head to clear her mind, she pulled back, and Jamie's hand fell away. "Anyway," Robin went on in a tense voice, "that's what I was talking about. I have a tight cunt, but I also had Sean's cock inside me without any trouble whatsoever. You just have to relax and let it happen. If you get scared, you tighten up and it'd be hard to even get a toothpick into your hole." She hoped she was being clear enough, but how did you talk about sex to a girl as young? Jamie wasn't exactly a child and she wasn't exactly in Robin's peer group and so the babysitter could only do her best.
"I think I get it," Jamie said. She looked at her brother. "Promise you won't hurt me?" He nodded solemnly, and the girl rearranged herself on the bed, so that she was almost sitting up. She put the panties underneath her ass once more, then slipped her legs apart so that her virginal twat winked open, and her arms reached out towards her brother.
Gently, carefully, Sean got between his sister's thighs, holding his breath as he lined up her pussy with his cock. Robin reached into the gap between their bodies, clutching at the boy's peter. She rubbed its tip up and down the raw red gate of Jamie's cunt, teasing until boy and girl alike were sighing with anticipation. "Pull your pussy open," she instructed Jamie, and the girl's little fingers flew down to tug at the lips of her snatch.
Robin could see the juice which drenched the rosy meat inside the young girl's puffy gash, and she knew that Jamie was as ready to get fucked as she'd ever be. Her breath was fast, her nipples were erect, and there was a pink flush of excitement on Jamie's upper body. "Okay," she told Sean, and her fingers led the knob of his dick into the tiny opening of his sister's twat.
The girl squealed when she felt the first penetration, but she willed herself to relax, to take it easy, just as Robin had instructed her. As more of Sean's knob inserted itself in her cunt mouth and the lips of her young twat stretched like rubber bands, Jamie raised her butt from the mattress. It didn't hurt! She gloated. It didn't hurt at all! Sure, it felt funny, but it didn't hurt!
And then his cock bounced against the baffler of her maidenhead. Jamie screamed at the agony of it, but her brother would not be denied. He moved forward, balancing his arms beside her half-risen body, and he pushed his throbbing cock in. Her cherry yielded gracelessly, straining as he thrust, and then it tore, allowing Sean's prick to plunge deeply inside her virginal cunt.
Jamie wanted to bawl but she couldn't. The pain was as sharp as the sudden puncture of her fingertip for a blood test at the Reckardsville Clinic, and it was just as fleeting. For a moment she hurt, and then the anguish was gone and she couldn't recall exactly how much pain she'd just felt. Sean's cock thrust hard as it passed the raw ruin of Jamie's cherry and she felt his rod coursing into her right, previously untapped channel, driving, driving, driving…
Robin jolted at the momentary look of panic on the young girl's face and she leaned forward, ready to intervene if it was necessary. But that strained expression almost immediately altered to one of interested participation. Jamie's eyes closed and her lips smiled and the pink tips of her chubby tits seemed to glow. When Sean's cock pulled back for a fresh stroke, Robin could see that it was daubed red with the vestiges of his sister's broken cherry, but there wasn't much blood, after all, and tat was for the best. A girl shouldn't be traumatized on her first fuck. Not that Jamie seemed in any danger of it. She tweaked and teased her stiff nipples and she shook her ass professionally as her young cunt swallowed up her brother's meat.
It hadn't worked out so badly after all. Could have been much worse. Of course, Robin reminded herself, she'd have to talk to them afterwards, convince them that this was only the beginning. No matter how much they enjoyed fucking each other, no matter how convenient it might be, they couldn't concentrate their sex drives upon one another. In that lurked danger. Sean must get over his shyness, if he hadn't already, and he must meet other girls, just as Jamie had to start meeting guys.
And wasn't she a poor one to be giving advice like that? Sean was only the second guy she'd ever fucked, for Dennis had taken her cherry and her heart with the same mighty thrust of his dick. Had he ever! She could feel his cock inside her hole right now, reaming her snatch like a dream. But they were all washed up. No chance they'd ever get back together.
She wondered if he was thinking about her now. But why should he? He had all those other girls at Columbus – that was why they'd quarreled in the first place, why they'd called it quits. So why should he think about an ex-girlfriend, even if she had trouble forgetting him? Watching the Willis kids fucking now in front of her made Robin that much more horny and, without a conscious effort, she moved her hand into her crotch and began to fondle her pussy with love and affection.
She teased the cuntlips that were still damp and swollen from her fuck with Sean, that were still a bit sticky from the jism he'd poured into her pulsating hole, and she pinched her clit to its pulsing arousal.
Her ass began to squirm, rubbing the chair seat as she watched and diddled, and Robin felt her passion building. She'd climaxed once or twice with Sean, but those were just baby comes, good only for making her cunt feel all squishy and oozy. The boy had enthusiasm and he showed a lot of promise, but he wasn't Dennis. Someday, when he got experience, Sean would be a very good lay and she hoped he found a girl smart enough to appreciate it.
Shouldn't she feel ashamed of herself? Her mind suddenly asked. For seducing a shy, virgin boy and encouraging him to bust the cherry out of his little sister's cunt? I don't feel wicked, Robin defended. Not at all. She hadn't done anything except go along with what was requested of her, morally speaking. Oh, sure, she'd given Sean the come on sign, but hadn't she woken from a sound sleep to find him raunching on her tits and trying to take off her panties? He'd made the advances.
And his sister? Robin hadn't invited Jamie into the bedroom. The girl came of her own free will, requested a demonstration of fucking with blackmail exposure as the alternative, and finally had instigated what was going on now her defloration by her horny brother. None of that was Robin's doing.
No. Robin Mackenzie was innocent of any wrongdoing. She was only the catalyst that had brought the Willis kids to their mutual sexual initiation. And from the way their bodies thrashed on the bed as they fucked, she was certain that they hadn't regarded each other with total innocence all these years. Robin had never had any siblings and she really had no idea what brother-sister relationships were like. Even so, she knew that this one was something else altogether. They fucked as if they were dying to make it, hotter, more desperate, than anything in Robin's own experience. She shook her head.
Robin was only half watching at the moment Sean's ass made a convulsing, quivering shake in the throes of orgasm. Her thumb and finger were playing a fast one-two on her love button and she was passing into the release of her own climax. She heard him groan, saw him collapse onto Jamie, and part of her mind knew that the boy was filling his sister's sucking little pussy with his fuck goo. Robin's cunt rippled excitedly around her inserted fingers and her clit throbbed in delirious tremors as vibrant warmth flooded her body. She felt her toes wiggling happily, as they always did when she came. She knew only that it was good. It was all very good.
