She'd gone too far.
This wasn't the first time Lucy had sneaked into Lincoln's room, but she had never before come so close to being caught. Now, she was trapped under his bed, where she had dived in panic when she heard the bedroom door start to open.
Lucy was only here because her long-standing coping mechanism wasn't working anymore. For over a year, she'd obsessed over Edwin from Vampires of Melancholia because being attracted to a fictional character was a safe, normal thing for a nine-year-old girl to do. Her sisters even supported it, or at least tolerated it.
But all that time, she'd simply been directing her passion away from its true target: her brother Lincoln. And she couldn't make herself do it anymore. Lincoln was twelve years old now, and the onset of his puberty had increased his already powerful appeal.
Lucy hadn't yet begun puberty herself, but she'd read enough gothic romance novels to understand that her attraction to her brother was not only romantic but also deeply sexual. At first, she thought that perhaps it was simply because she had an old soul, and thus was having these feelings at an unusually early age. But over the past few weeks, she'd come to realize that it was all about Lincoln. She didn't have these feelings for any other boy, not even Rocky.
The only way Lucy could think of to deal with this increasingly urgent need was to sneak into Lincoln's room when he wasn't there and lie in his bed, inhaling his residual scent in his bed linens. And to reach down beneath the waistband of her skirt and touch herself while she did it.
Now, hiding under the bed, she heard him close the door. Then, able to see only his bare feet and ankles, she watched him push the back of his desk chair under the doorknob, effectively barricading the door.
Does he know I'm in here? Lucy thought wildly. Is he trapping me in here with him so he can punish me somehow? Or so he can do…other things, to me?
She forced herself to calm down and think rationally. Barricading the door like that would keep people from entering the room, but it wouldn't stop anyone already inside from simply moving the chair and leaving.
Then Lincoln walked toward the bed. Lucy held her breath, hoping that he hadn't seen her dive under the bed. But to Lucy's immense relief, Lincoln didn't come down to his knees and look beneath the bed frame. Instead, he just lay down on the bed, making the springs above Lucy squeak.
What is he doing? Lucy wondered. Maybe he wants to take a nap without risking one of the girls busting in and waking him up. Which is a serious risk.
She heard the clinking sound of a belt buckle being undone. Then came the more easily recognized sound of a zipper.
Why is he undoing his pants? Lucy thought. Then she remembered what she had just been doing in her brother's bed and thought, Oh my gosh, is he about to…?
She heard rhythmic movement, and she knew that she had guessed correctly. Lucy listened desperately, wishing she had the ears of a werewolf so that she could hear every nuance of her brother's movements and breath as he pleasured himself. And she had to slap a hand over her mouth to keep from squealing with excitement when she heard Lincoln speak.
“Oh, yeah, take it…” Lincoln murmured. “Take it all…all the way in…that's right…take it deep…take it to the balls…”
'All the way in'? Lucy thought. 'Take it deep?' Does that mean he's…big? Or is he just fantasizing that he is?
Oh, spirits help me, I need to know. I need to see it. I can't just lie here, this close to him, this close to his exposed, hard cock and not see it, or I'll die, I know I will.
Surely she could get away with taking at least a peek. She always closed her eyes when she touched herself; Lincoln was probably doing the same. He wouldn't see her tarry black hair and eye-hiding bangs rise up at the edge of his bed.
As quietly as she possibly could, she eased her body out from beneath the bed. Then, as though she were rising from the grave, she slowly sat up facing Lincoln.
Her eyes grew enormous as she gazed at him—specifically, at what was in his hand. Because it was impossible. No boy could have a penis that large, especially not a twelve-year-old one. She blinked hard, thinking that she had to be mistaking his forearm for his…thing. But she wasn't.
Only when Lincoln's eyes flew open did Lucy realize that she had gasped aloud.
“Lucy?!” he exclaimed, trying to pull his tighty-whities back up and only partly succeeding because of his hardness—and hugeness.
Lucy wanted to run. She wanted to try to explain. She wanted to burst into tears and plead for forgiveness.
But she had another urge that was more powerful than any of those, and before she even knew what she was doing, she followed it: She grabbed Lincoln's immense cock in both hands and began to kiss and lick it all over, rapidly, ravenously.
“Ohmigod!” Lincoln gasped.
But he, too, was now in the thrall of instinct. He didn't try to stop his little sister from seemingly devouring his cock; there was no room in his mind for any thought of how wrong this incestuous act was, or how he, as the older sibling, had a duty to prevent it.
No, all Lincoln could do was what he did: He sat up and quickly wrestled off his orange polo shirt, then grabbed the hem of Lucy's short black dress and pulled it up, too.
“Oh yes, please, take off my clothes,” Lucy gasped, releasing Lincoln's member and raising her arms so that Lincoln could pull her dress off.
Now, Lucy had on just her plain black panties and her black-and-white striped stockings and arm wraps. She quickly lay down on her back and raised her hips to push the panties down, but Lincoln beat her to it and yanked them down to her ankles. Lucy kicked them off.
Lincoln, sitting up, raised his legs and pushed his jeans and underwear the rest of the way off. At the same time, Lucy lay back on the bed and opened her legs wide.
Now Lincoln was naked, and Lucy was naked enough. He looked eagerly at her pussy, which was hairless but soaking wet.
“Please,” Lucy gasped, “put it inside me. I'll die if you don't. I don't care how much it hurts.”
Lincoln was so horny that there was no way he could do anything else—not with Lucy begging him like this. He moved on top of her, reached down between their bodies, and put his cock between the lips of his little sister's hairless sex. Then he pushed.
“Aaaaaah!” Lucy cried.
The penetration was the sweetest pain she'd ever known. And then he pushed in deeper, entering more of her, taking more of her. She began weeping from the pain and the unmitigated joy of it, and she feared that her tears would discourage Lincoln from pushing in further. So she held him tight with both her arms and legs.
“Please don't stop,” she sobbed. “Please, I need this, I need it so much…”
Lincoln pushed in and in, amazed that his nine-year-old sister had already taken half of his substantial cock and was still taking more.
He finally hit bottom inside her, and Lucy moaned. She had a full nine inches of her brother's cock in her, penetrating her right to her womb, and nothing else in her life had ever felt half so good.
At least, until Lincoln started fucking her.
“Oh Lincoln,” Lucy gasped. “That feels so good…”
It had taken a lot of self-control for Lincoln to push slowly into his little sister's open, inviting pussy and then to start fucking her gently, letting the girl get used to his size. But now that he could hear how much she was loving it, his control was beginning to slip, and he began to fuck her a little faster. Which made Lucy moan a little louder.
Out in the hallway, Luna was walking carefully and quietly toward Lincoln's room. She had left her spot in front of the TV to run upstairs and quickly change into her nightgown before the commercial break was over. But then she had heard an odd cry, in a voice that didn't sound like Lincoln's, come from behind her brother's bedroom door.
What could be going on in there? The cry had sounded…sexual. Which Luna couldn't help but find arousing.
She crept up to the door. It was closed, but every girl in the house knew that Lincoln's bedroom door, even when fully closed, had a decent crack through which you could see a portion of the room, including Lincoln's bed.
She put her eye to the crack and had to slap a hand over her mouth to keep from gasping aloud. There was Lincoln, face-down on his bed, his hips slowly pumping up and down, forward and back. And on either side of those hips were two slender legs raised high in the air.
Lincoln's fucking a girl! Luna thought, pressing her hand to her mouth even harder to ensure that she merely thought it and didn't scream it. Then she noticed the telltale black-and-white striped stockings on those raised legs. Lincoln's fucking Lucy!
Luna felt a churning typhoon of emotions: shock, arousal, and burning jealousy. Having caught the odd glimpse of Lincoln in the buff over the years and guessed that he would be very well endowed one day, she had always hoped to be the one to help Lincoln do away with his virginity. Once, while her sister and roommate Luan was off at one of her birthday-clown gigs, Luna had “borrowed” her mom's ten-inch vibrator, locked the bedroom door, and shoved the buzzing sex toy it so far up her pussy that even the base disappeared inside her, thus giving herself a powerful orgasm. Removing the vibrator afterward had been a little tricky, but now Luna knew that her pussy could take a cock of just about any size that human cocks came in.
That day, Luna became even more resolute in her decision to seduce Lincoln when the right moment came. She even bought a batch of purple panties edged in lace that were comfortable enough to wear every day but that would look sexy on her whenever the moment came to show her body to her little brother.
Now, Luna could scarcely believe that her preadolescent little sister had beaten her to it. Apparently, deep pussies ran in the family.
Inside the room, Lincoln started pumping Lucy faster. Her utterly wet, astonishingly deep love-tunnel felt better than his hand ever had or, probably, ever could.
“Oh…yes…Lincoln…” the young girl moaned in her gravelly voice. “Don't stop…please…you feel…so good…inside me…”
Lincoln fucked her faster still, panting, “Yes…Lucy…so good…so tight…”
Luna quickly glanced behind her. Seeing no one in the upstairs hallway, she thrust her hand down into her jeans and rubbed her clit ardently, almost frantically.
Lucy held on to Lincoln, addicted to the feeling of his cockhead hitting her special deep place again and again. She never wanted to live another day without this, without him doing this with her, to her, in her.
Lincoln couldn't take how good this felt. He needed to reach his climax, or he would surely lose his mind. So he fucked Lucy as fast and hard and deep as he could.
“Ah!” Lucy cried, overwhelmed. “Ah! Ah! Yes! Ah!”
The bedsprings squealed, and Lincoln and Lucy's bodies bounced on the bed from the vigor of their fucking. Luna, watching avidly, rubbed her clit furiously as she imagined that it was her legs in the air, her thighs alongside Lincoln's hips, her pussy taking all of that cock. Luna's fantasy became even more vivid and arousing when Lincoln, whose eyes were squeezed shut as he plowed his little sister hard, began to speak in what was barely more than animal grunts.
“Yeah…take it…Take…my cock…Take it…deep…”
“Yes! Yes! Deep! Yes!” Lucy cried. “Make…me…take…it…AAAAAAALLLLLLL!”
“HUAAAAAAH!” Lincoln shouted, and then Lucy felt her brother's semen flood into her womb, so very hot and so very much, and she screamed even higher and louder as her climax, which already far surpassed any she'd had before, became unbearably powerful.
“AaaaAAAaaah!” Luna shouted, cumming along with her siblings.
Lincoln couldn't hear Luna's cry over Lucy's and his own. But when his climax was finished and he lay on top of Lucy with his cock buried inside her, he heard a stumbling footstep just outside the door.
“Who's out there?” Lincoln gasped.
Even though Luna had cum so hard that she was woozy, getting herself off had done nothing to dull Luna's desperate desire for Lincoln and his enormous cock. Her lust still burned unbearably, and Luna knew she would lose her mind if she didn't get her brother's beautiful monster-cock inside her right now. So she had no choice but to be direct.
“It's Luna,” she answered, trying not to whimper. “Please let me in. I need you to fuck me, too. Please!”
Then Luna remembered the words that Lincoln had grunted to Lucy when they were fucking. Quickly, she added, “I promise I'll take your whole cock. You can shove it all in me! Every inch!”
Luna's words and the haste with which she'd spoken them made it clear to Lincoln how desperate the teenager was—which was starting to make Lincoln get hard again. He'd feared that his size would scare girls off, so it was exciting to discover that at least some girls instead found his big dick irresistible.
He got up from the bed, moved the chair out from under the doorknob, and opened the door. Luna rushed in and slammed it shut behind her, then quickly put the chair back under the knob.
She was now looking directly at her naked brother, and her gaze immediately dived down to his crotch. Even though his cock—still slick and shiny with his cum and Lucy's natural lube—was mostly flaccid, it had the thickness of a firehose, and Luna could see how heavily it hung.
Luna couldn't help herself: Before Lincoln could say a word, she dropped to her knees in front of him, seized the base of his big cock in her hands, and shoved as much of his member into her mouth as she could. Then she sucked it hard, swallowing down all of her brother's residual cum.
“Omigod!” Lincoln gasped.
Lucy was still lying on the bed, bathing in a magnificent afterglow. She chuckled aloud at the thought that Luna, who was nearly twice Lucy's age, had made herself a slave to Lincoln's cock just as quickly and eagerly as Lucy herself had.
Lincoln could scarcely believe all this was happening. He'd just had sex for the first time with one sister, and now he was receiving the first blowjob of his life from another sister. And wow, did it feel good. He found himself putting his hands on Luna's head, not wanting her to take her mouth away for even a moment.
Luna, sucking Lincoln's cock like a famished calf at its mother's teat, could feel her brother's member going hard in her mouth. She had to open wider and wider to avoid touching that precious member with her teeth.
One day, she thought, she would learn to do more than this, to give Lincoln a for-real blowjob that was good enough to get him off. But right now, she desperately needed that cock inside a different part of her. So she pulled her head back, out of Lincoln’s grasp, and let his cock fall out of her mouth.
Lincoln was momentarily disappointed. But then Luna pulled off her nightgown, showing him the small curves of her bare breasts and the way her lace-edged purple panties seemed to cup her pussy enticingly.
With as much presence of mind as she could muster, Luna gave Lincoln a smile and a moment to look before she pushed the panties down and off. Then she lay down on her back on the bed, managing to squeeze in next to Lucy, and spread her legs.
“Please, bro,” she gasped, “let's get it on.”
Lincoln got on top of her and positioned his cock against Luna’s pussyhole. Luna being almost a head taller than Lucy, Lincoln was able to see the expression on Luna’s face as he started to push in. The girl’s eyes closed and her lips parted, and the bliss on her face seemed to increase with every inch that Lincoln eased into her.
Luna put her hands on her own small breasts and squeezed them. Even though she’d desperately needed Lincoln to put his cock in her, she still couldn’t believe how good it felt going in…and in, and in.
“Yes, bro, yes…” she gasped. “Fill me up, I wanna take it all, make me take it all…”
Only then did Lincoln hit bottom inside Luna. He could scarcely believe his eyes: No more than a half-inch of his length was still outside her.
Excited to be so deep inside his big sister's pussy, Lincoln began fucking her immediately. He wasn't quite as desperately horny as he had been when he'd fucked Lucy, but he was definitely headed in that direction.
So, as he had with Lucy, Lincoln found himself using words with Luna that he had so long used only with the faceless girls in his fantasies. But this time, Lincoln was in a position to speak more coherently, albeit not with any less feeling.
“That's it…” he breathed as he pumped her. “Take my cock…take it all…take it in you to the balls…”
Saying these things to a real girl was arousing. But not as arousing as Luna's reply.
“Yes…bro…fuck me deep…shove it deep inside me…Every inch of my pussy…belongs to you…all the way to my womb…My cunt was made for you…”
Lincoln fucked her faster. Luna wrapped her arms and legs around him and murmured in his ear.
“Please…yes…don't stop…as long as…you fuck me…I'll do anything…you want…I'll suck it hard…swallow all your cum…let you fuck me whenever…you feel like it…you can even…knock me up…if you want…just don't ever stop…”
Lincoln was elated by these promises. With his size, he'd never thought any girl would give him free access to her body. And the idea of getting his big sister pregnant was crazy wrong yet aroused him like mad.
“Oh yeah?” Lincoln panted in Luna's ear. “'cause when I shoot…my cum inside you…it's gonna be a lot…you could definitely get…knocked up…”
“I don't care…” Luna moaned. “Just keep fucking me…”
Lincoln couldn't help but fuck Luna faster. In the back of his mind, he wondered if she was having one of those “safe days” he'd heard women had. He also wondered whether any day was safe for a daughter of champion baby-maker Rita Loud. Or whether any day was safe from the son of champion impregnator Lynn Loud Senior.
Luna was moving her hips in time with Lincoln's, making sure his cockhead kissed the entrance to her womb on every stroke. The truth was, now that she thought about it, she wasn't merely willing to let Lincoln get her pregnant; she wanted him to get her pregnant. Which seemed crazy, because she was sixteen and had her whole life ahead of her. But right now, she couldn't imagine wanting any life that didn't involve giving herself over completely to Lincoln, body and soul. That included having his baby—no, babies. Lots of them. Her dad had put eleven kids in her mom; maybe Lincoln could put twelve in Luna.
“Yes, Lincoln…” she panted in his ear. “Knock me up, bro…I wanna have your baby…”
Lucy, lying next to her fucking brother and sister on the bouncing bed, was just beginning to emerge from her pleasant state of afterglow. Hearing Luna's words, Lucy couldn't help but envy the older girl. Lucy, too, wanted to have Lincoln's baby, but it would be years before she would be old enough to get pregnant. She would need to find another way to make Lincoln want to fuck her as much as he did Luna.
Turned on beyond all reason, Lincoln fucked Luna hard and fast. The bedsprings squeaked loudly and rhythmically, and Luna grunted in much the same way.
“Uh! Uh! Uh! Uh!” she cried as Lincoln's cock pounded her inside. Like Lucy had, she raised her legs in the air, encouraging him to hit that deep place within her even harder.
Lincoln energetically obliged. He, too, grunted with the effort of their mating. Now, he was nearing his climax, so he poured it on and fucked Luna as hard as he possibly could.
“AaaaaaAAAAAH!” he shouted, and then he was shooting one gout after another of thick, hot, fertile sperm straight up into his big sister's womb.
Luna could feel her body drinking in that hot flood of semen, her womb swallowing it as fast as Lincoln could pump it into her, and then she screamed, hitting a high note she'd never known she could reach as she clutched Lincoln to her and wordlessly begged him not to stop cumming inside her until she was full.
Lincoln felt as though he were shooting cum into Luna by the pint—more even than he'd shot into Lucy. It was as though something primal inside him wanted to make certain that he put as much fertile seed into Luna's womb as his body could possibly manage. And the screaming Luna's body drank it all in.
Finally, their climaxes came to an end, and they lay in a panting, heaving tangle. Lincoln kept his cock cervix-deep inside Luna until it started to soften; then, slowly, he pulled out and rolled off of her. Luna snatched up her purple nightgown from the floor to absorb the substantial amount of cum that flowed out of her open pussy.
Lucy was still lying there quietly, but inside, her emotions were roiling. She was jealous of Luna, and afraid that Lincoln had liked fucking her better than he had liked fucking Lucy. But most of all, Lucy needed Lincoln's cock back inside her, any way she could get it.
Not that Lucy was inclined to say any of this out loud. Instead, she simply looked at Luna and said, in her usual gravelly deadpan tone, “You didn't keep your promise.”
Luna had been floating in the haze of afterglow. Now, Lucy's comment penetrated that haze.
Puzzled and a bit annoyed, Luna sat up and replied, “Dude, what're you talking about?”
“You promised Lincoln you'd take his whole cock,” Lucy said. “But you didn't. Even on his hardest, deepest thrust, you couldn't take the last half-inch of him.”
She eyed Lincoln wickedly as she finished, “But I can.”
“What?” Luna sputtered, outraged. “No you can't. You didn't even get close!”
“I didn't mean that way.”
A couple of weeks earlier, Lucy had been composing a poem inside one of the house's heating ducts when she'd heard whispering and giggling coming from Lori and Leni's room. The whispering wasn't that unusual, and the giggling certainly wasn't, but the two together suggested that the girls were talking about something particularly interesting. So Lucy had crawled close to their bedroom’s vent to listen in.
“Did you know,” Lori was saying, “there are some girls who can swallow a boy's dick?”
“But,” Leni replied with concern, “then the guy wouldn't have a dick anymore.”
“No, his dick doesn't come off. The girl just takes more and more of it into her mouth until the tip of it goes down her throat. They say if a girl does that, the boy will literally cum, like, instantly.”
Lucy half expected Leni to ask, “Come where?” But apparently, she and Lori had already had that conversation, because Leni just said, “Wow, that's so cool! But how do you do it?”
“Beats me,” Lori replied.
But it didn't beat Lucy. She was well read in a variety of bizarre subjects, and she had learned how sword swallowers suppressed their gag reflex. And upon learning that a girl could swallow a boy's cock in the same way, she'd found herself fantasizing about doing that for Lincoln. A week or so earlier, she had even “borrowed” the rubber dildo that Lori seemed to think was safely hidden under her mattress, took the toy back to her room, and managed to swallow it to the base while she rubbed her clit and thought of Lincoln.
Of course, as it turned out, Lincoln's cock was almost twice the length of Lori's rubber one. But that didn't scare Lucy at all; if anything, it made her even more determined to swallow him to the balls.
So Lucy rolled over and then scootched down, putting her face directly above Lincoln's crotch. Her brother's cock might have been largely flaccid and covered in cum and Luna's love juices, but it still looked beautiful to Lucy. So she wrapped her small, pale hands around the base, opened her mouth wide, and took the head inside.
“Mmmm…” she moaned as she suckled it. Having Lincoln's thick cock in her mouth may not have been as physically stimulating as having it in her pussy, but it was exciting in that it felt like an act of worship. And Lincoln's enormous cock deserved Lucy's worship.
With that in mind, Lucy closed her lips around Lincoln's big member and began moving her head up and down, massaging the first few inches of its length. She had learned this trick during her deep-throat research and had practiced it on the rubber dildo.
Lincoln could hardly believe how good this felt. Luna's oral ministrations had been enough to get him hard again, but all she had really done was suck. Lucy's oral cock-massage was far more sophisticated—and more stimulating.
Lucy kept this up for a few minutes, listening to Lincoln's increasingly heavy breathing and using both hands to fondle her brother's heavy balls. The only thing she wanted in the world right now was for him to empty those balls into her body again.
She took a deep breath through her nose. Then, swallowing continuously, she pushed her head down. Lincoln's cockhead went to the back of her throat and then down it as Lucy gulped repeatedly. Lincoln could feel his little sister's throat muscles massaging more and more of his cocklength as his shaft continued to disappear into her mouth.
Luna watched in awe. She could actually see Lucy's whole throat bulging with Lincoln's girth, and more importantly, she could see the intense pleasure on Lincoln's face. Luna vowed to herself that she would learn to do this, too.
Finally, Lucy's forehead was pressed against Lincoln's stomach while her chin touched the base of his balls. She had swallowed his entire length, and she felt an incredible surge of pride. But she also felt humility: This act, however challenging, was still less than Lincoln's god-like cock deserved.
So Lucy again moved her head forward and back, this time massaging Lincoln's cock not only with her lips but with her tongue and the entire length of her throat. The feeling was so erotic that she began to rub her clit as she moved.
Lincoln had heard schoolyard talk about deepthroating, but given the size of his cock, he'd never expected any girl to do it for him—certainly not his nine-year-old sister. So he'd never even allowed himself to fantasize about it.
But even if he had, his fantasy could not have lived up to the reality. Lucy was making his cock feel incredibly good from base to head. Most stimulating was the way the rings of muscle in her throat stroked the entire circumference of his glans every time she swallowed, which she did over and over.
Not stopping her head movements or her swallowing, Lucy looked up at Lincoln's face. Then, with both hands, she pulled her bangs away from her eyes so Lincoln could see them, even as reflexive tears leaked from their corners.
Now I am truly naked for you, Big Brother, she thought. Now you can see all of me. Because all of me is yours, forever and ever.
Lincoln hadn't thought that anything could be more arousing than what Lucy was doing for him with her throat. But now, looking into her eyes, he could see the adoration in them. More than that, he could see that he and his cock were everything Lucy wanted, needed, and hoped to be worthy of. She was giving herself to him.
He put his hands on her face. It was a gesture of affection, but also of control. She was submitting herself to be used by him, and he wanted—no, needed—to use her.
Keeping his cock deep in Lucy's throat, Lincoln moved the two of them from the bed to the floor so that he was standing and she was kneeling before him. Being put in the proper position to worship Lincoln and his cock sent a hot flush of arousal through Lucy's whole body.
The young goth started to move her head forward and back, and this time, Lincoln moved his hips in time with her head, ensuring that his cock went balls-deep in her mouth and throat again and again. Soon, Lucy didn't need to focus on moving her head anymore, because Lincoln was using his hands to do that for her, so she could focus solely on using her lips, tongue, and throat muscles to pleasure him as he gently fucked her face.
It was only because Lincoln had cum twice already that he was able to keep up this slow pace for the next few minutes. Nonetheless, his excitement soon grew to the point where he had to fuck Lucy's face faster…and faster…and faster, until he was pumping as fast and hard and deep as he could.
His big balls repeatedly slapped against the cock-bulge in Lucy's throat, which the girl found immeasurably erotic. She rubbed her clit rapidly, and even though Lincoln's eyes were now squeezed shut with the effort of fucking his little sister's mouth, she didn't stop looking up at his face.
“Nnnggglll,” she moaned in her full throat, orgasm nearly upon her. “Nnnggglll! Nnnggglll! NNNNNGGGGLLLLLLLLL!”
As she came, every muscle in her body spasmed wildly, including those in her throat. And then Lincoln cried, “AAAAAAAAAAAHHHH!” and shot an immense load of cum straight down into Lucy's stomach. Feeling the heat and thickness of it in her belly made her cum even harder.
Even when Lincoln finished shooting his load into her, Lucy kept sucking, kept swallowing. She didn't want to lose a single drop of Lincoln's cum, to let it go anywhere but deep inside her where it belonged.
Inch by inch, Lincoln pulled his cock out of Lucy's mouth. The girl continued to suck and swallow until Lincoln's cockhead finally passed her lips and the boy's member fell and landed with a wet slap against his thigh.
Luna had watched this entire event with astonishment. She'd had no idea that Lucy was capable of such a feat. Obviously, Luna would need to learn to do the same thing, and do it better than Lucy, if Luna was going to prove herself more worthy of Lincoln's sexual attentions than her little sister. But right now, Luna was pretty sure she would need some practice before she could swallow Lincoln's cock like that without either puking or passing out.
Fortunately, Luna had another idea.
“Well, that was pretty cool, Luce,” Luna conceded. “But I've got a surprise for Linc, too.”
Lincoln had just sat down on the bed. Luna turned to him, then reached over to fondle his big balls as she spoke.
“Hey bro,” she said, “wanna put that big beast of yours up my ass? I guarantee I can take every inch of it in there.” She ran a hand down her ass sexily as she added, “I'm hot just like an oven, and I need some lovin'.”
Having cum hugely three times already, Lincoln had thought that it might be hours, if not days, before anything could get him horny again. But he had also thought that no girl would ever let him put his outsized cock up her butt—let alone that it would be the girl's idea. So Lincoln's member began to harden yet again.
Luna smiled at the sight, then leaned down and licked her brother's balls. She was focusing her efforts there because his cock was still slick from Lucy's suck-job, and Luna didn't want to have to leave the room—more specifically, she didn't want to have to leave Lincoln alone with Lucy—to go find some other form of lube. Fortunately, caressing Lincoln's heavy gonads seemed to be working: Lincoln's massive member was growing stiffer with Luna's every lick.
Once he was good and hard, Luna got up on all fours, presenting her cute, lightly freckled ass to her brother. Then she lowered her head and shoulders to the surface of the bed so she could reach back with both hands and spread her asscheeks open wide for Lincoln, showing him her petite pink hole.
“Go ahead and put it in, bro,” Luna said, trying to keep the anxiety out of her voice. “All of me is yours now, so why not take all of me?”
Lincoln didn't have to be asked twice. He wasn't sure if his cock was really going to fit in that tiny little hole, but the prospect of ass-fucking Luna was so arousing that he was dying to find out.
So he put the thick, cum-slicked head of his cock against that little hole. Then, as gently as he could make himself, he pushed.
The hole barely opened. Certainly not anywhere near enough for a cock with the girth of Lincoln's to get inside.
Luna felt a pang of anxiety. It would be mortifying to have bragged about being able to take Lincoln's whole cock in her ass and then not being able to take any of it at all. Surely that would just about guarantee that Luna would lose Lincoln to Lucy.
“Just force it in, bro!” Luna pled. “I don't care how much it hurts, just keep pushing till you're in!”
Few things could have made Lincoln want to hurt Luna physically. But the fact that she was begging him to do it, combined with Lincoln's rapidly growing horniness, was making his qualms blow away like mist in a sudden gale.
So Lincoln pushed harder. And the little hole started to open.
“That's it…bro…” Luna gasped. “Take…my ass…It's all…yours…”
Luna did her best to make her virgin asshole open wider for her brother, but it was clear that only the force he applied could open her up enough for him to penetrate. So Luna just dug her fingers into the bedcovers and tried not to whimper or groan as Lincoln's cockhead forced her little hole open wider and wider. Soon, though, Luna couldn't help but make noise as her hole opened farther than nature had ever intended.
“Uhhh…ahhhhh…” she moaned. Then, fearing that Lincoln might give up, she managed to grunt, “Keep…going…”
Lincoln kept pushing, and Luna moaned louder. Then, just when she thought she might tear in half, she felt her brother's thick cockhead push into her.
“Oh yeah,” she gasped. “Yeah, yeah, yeah, keep going, bro…”
Lincoln couldn't believe that he'd made Luna's tight little hole stretch so far open. The pink of it was white now as it strained to take the girthy cockshaft that he was now slowly sinking into Luna's ass.
“Ohhhh, yeahhhh…” Lincoln breathed.
Even though he had already done the hardest part by forcing it to open this wide, Luna's hole was gripping his member so tightly that it still took some effort to get in deeper. But Lincoln was loving that. Luna had given him license to invade her ass by force, and he was going to conquer every inch of it that his big member could reach. So he pushed and pushed, listening to Luna's non-stop moans as he shoved more and more of his thick shaft into her virgin ass.
“Bro,” Luna gasped, “is it all the way in yet?”
“Nuh-uh,” Lincoln replied truthfully. “Only about halfway,”
“Oh my God,” Luna whimpered. Then, fearing that Lincoln might think she was chickening out, she quickly said, “Keep going, bro! Don't stop till you're in me to the balls!”
“Don't worry,” Lincoln breathed. “I'm not stopping for anything.”
Luna gasped, panted, and moaned as she felt Lincoln's huge cock go deeper and deeper into her ass. Just when Luna began to fear that she was running out of room inside and that Lincoln wouldn't be able to get his entire length into her ass after all, she felt his big balls come to rest against her pussy.
“Wow,” Lincoln breathed. “It's all the way in. It's so hot inside you, Luna.”
“Just wait…till you start…fucking me…” the teenager gasped.
Lincoln smiled and replied, “I don't think I wanna wait.”
Slowly, he pulled his cock most of the way out, then pushed it all the way back in, eliciting a long moan from Luna. Then he did it again, and again, savoring the tightness of her hole around every millimeter of his length. Lincoln had never really allowed himself to fantasize about anal sex, fearing the disappointment of that fantasy never becoming reality. But he was sure that if he'd had such a fantasy, this experience would have lived up to it—if not surpassed it.
Lucy, who had been watching quietly, could hardly believe what she was seeing. She hadn't actually believed that Luna could take any amount of Lincoln's cock in her ass, let alone the whole thing. Lucy knew she herself wouldn't be able to take Lincoln's cock that way; Luna could barely take it, and she was a lot bigger than Lucy. But Lucy resolved that she would train her asshole to accommodate Lincoln's massive member, perhaps by fucking her hole with Lori's dildo and then with progressively bigger things. Lucy wouldn't care how much it hurt as long as it gave her a new way to take Lincoln's cock.
Despite herself, Lucy found herself becoming aroused from watching Lincoln deflower Luna in this way. Maybe it was the perversity of watching anal sex between siblings; maybe it was also schadenfreude at her older sister's obvious discomfort. But the reasons didn't really matter, Lucy decided as she began to rub her clit.
As Lincoln continued slowly pumping his big sister's ass, Luna's pain slowly diminished, and her pleasure slowly grew.
“Ohhhhh, bro,” she gasped. “Sex me up…”
He started pumping her a little faster. For Luna, this increased the sensation of pleasurable invasion, and she began to move her ass in time with Lincoln's hips.
Luna's enthusiasm cranked Lincoln's arousal a notch higher, so he increased his fuck-speed further. Luna moved her freckled ass faster in response. She also began making a rhythmic moan whose tone and volume rose and fell with her movements.
Lucy rubbed her clit faster. Watching Lincoln's cock plunge into her big sister's asshole again and again, the boy's hips bouncing off her slender ass each time, was more exciting than Lucy would have expected. The sound of Lincoln panting and grunting against the background of Luna's non-stop moaning was pretty arousing, too.
For Luna, the first assfuck of her life had in minutes gone from nearly unbearable to tolerable to nice to the most erotic experience of her life. That long, thick cock going so deep inside her again and again made her feel so very full, even more than when Lincoln had fucked her pussy. She felt completed by him, mastered by him, owned by him, and it made her feel sexier than anything ever before.
“Ooooh, yes, Lincoln,” she sighed. “Fuck my ass…it belongs to you now…”
“Oh God yeah,” Lincoln exhaled. “I wanna fuck your ass…and own your ass…forever…”
Lincoln sped up further, loving how it felt to get every one of his many inches of cocklength into Luna on every stroke. Luna moaned loudly and fucked her ass harder against Lincoln's thrusts.
Although his thick cock plundering her insides was the focus of Luna's attention, to the point of eclipsing almost everything else in her sensorium, she could also feel his heavy balls slapping against her pussy on every thrust. Which gave her an intensely arousing thought.
“Cum…in my ass…bro…” she panted. “I wanna…feel…your hot…cum…way up…inside me…please…ring…my…bell…”
Hearing his big sister plead for a load of his cum deep in her ass was more than Lincoln could bear. He plowed Luna as hard as he could, making her alternate among gasping, moaning, grunting, and screaming while at the same time thrusting her ass back against him as hard and as fast as she could.
Lucy, her eyes glued to this scene, rubbed her clit at maximum speed even as she worked a finger into her asshole. She couldn't help but imagine how magnificent Lincoln's cock would feel inside her own ass, going in balls-deep again and again, pumping her, filling her, using her. She definitely would be training her little rear hole to take him.
“Ah! AH! AH! AH!” Luna cried as Lincoln pounded her ass. “I'm gonna…I'M GONNA…AAAAAAAAAAAAAH!”
When Luna came, her asshole gripped Lincoln's cock with incredible force, thereby increasing the already intensely pleasurable friction between Luna's hole and Lincoln's member. The boy shouted “Hyaaaah!” and shot his load deep into his big sister's ass.
That hot cum—so much hot cum, despite Lincoln having shot three loads already—flooding Luna's ass felt even better than she had imagined. The pitch of her orgasmic scream rose higher, and as Lincoln shot even more of his hot seed into her, her climax went on and on. Lucy, too, cried out in pleasure, her orgasm hitting surprisingly hard.
When it was finally over, Luna was panting for breath. Lincoln's cock was still buried in her ass, and that plus his copious load of cum made her feel as though her brother had completely taken possession of her body, to occupy and use however he wished. It was an intensely erotic thought. On top of that, Luna could scarcely believe how immensely pleasurable this assfuck had been. At first, she could barely stand it, but now, she never wanted to go another day without it.
Lincoln couldn't believe that he had, in the space of one afternoon, lived out so many of what he thought would never be more than fantasies. It was amazing, beyond amazing.
But how was it going to end? Was he going to have to choose between Lucy and Luna? And what other consequences would the events of this afternoon have? It seemed like there were a zillion ways in which this all could turn out very badly—for him and for his two horny sisters.
The thought made him go soft, and he pulled out of Luna's ass. Luna let out a long sigh and looked back over her shoulder at Lincoln.
“So…bro…” Luna panted. “That was…better than…anything…right?”
Urgently, Lucy jumped in. “Please choose me, Lincoln. I’m the only one who can swallow your cock to the balls.”
“C’mon, bro,” Luna countered, “you know I’m the one you want.” She licked her lips and ran a hand over her freckled ass and past her gaping hole as she added, “You can put that sweet cock up me whenever you want, as much as you want. Just say the word and I'll come to your room and bend over for you. Any time, day or night, I'll be around.”
“You could do the same with me,” Lucy rejoined. “And not just in your room. Imagine how much nicer a long ride in Vanzilla would be if you could just sit in the back row of seats with a blanket over your lap, and me underneath it with your cock down my throat for all those hours.”
Luna turned around to face Lincoln and ran her hand over her stomach as she said, “I’m the one you can knock up, bro. If you haven’t already.”
Thinking quickly, Lucy rejoined, “Maybe you can’t get me pregnant—yet—but I can talk Lynn into letting you knock her up.”
Lincoln’s cock twitched. Now that Lucy had put the idea in his head, getting his cock into Lynn’s fit, trim body sounded awfully appealing. Especially if it would turn her into his cockslave like it had Lucy and Luna. And getting Lynn pregnant would be the perfect way to cement his position as the alpha wolf in that relationship.
Desperate not to be outdone, Luna said, “Well, I can…I can get Luan to let you preg her. Probably Leni, too!”
Lucy struggled to think of something better. She couldn't, but at least she thought of a way to derail the game of one-upmanship.
“I hope it's my turn again,” she said, a pleading note behind the words. “I need your cock back inside my body.”
“And then my turn again,” Luna added with the same needy undertone.
Lincoln smiled. Then he reached down and cupped one of Lucy’s asscheeks with one hand while taking one of Luna’s breasts in the other.
“Don’t worry,” he said. “I don’t need to choose between you, ‘cause there’s plenty of me for both of you.”
He was no longer worried about how this was going to end. Because obviously, it never would.
