After having left his dysfunctional family as a young adult, Lucas gets an unexpected visit from his cruel little sister, who demands an explanation and that he takes responsibility for his wrongdoings.
WARNING: Contains non-con and incest.
Finally weekend. After five days of near non-stop studying, it was finally time to enjoy a well-earned reward for his hard work. Perhaps eat some takeout? Go see a movie? Buy some booze and throw a party? Maybe just stay at home and play some video games?
Lucas chuckled to himself as he walked up the staircase to his apartment. “As if,” he mumbled, amused by his own wishful thinking. As if he had money for any of those things. He knew damn well what awaited him in his apartment: Empty floors, broken heaters, a pantry with nothing but instant noodles. And of course, what didn’t await him was any form of entertainment. Not even a TV. Yup, this was going to be yet another weekend of nothing but studying; not because he was a model student or anything, but rather because there was simply nothing else to do.
Life as a poor student was hard. A part-time job could only cover so many expenses, and being forced to continuously buy a bunch of expensive books for his studies meant that there was no way for him to save money for other things he desperately needed, such as a computer and internet connection. He did have a cell phone, an old, crappy thing that he had stuck with for several years, but his two gigabyte data plan was barely enough to get him through the month.
Sighing heavily, Lucas turned the lock to his door and opened it with a tired tug. As light flooded the living room when he flicked the switch next to the door, the sad sight of the near empty apartment almost made him wish he was back at school. At least he would have someone to talk to then.
He dragged his feet over to his bedroom, threw his backpack on the bed and plugged his phone - which had been dead for a good hour - into the charger, before making his way to the kitchen to boil some water for his depressing noodle dinner. So far this Friday had played out like any other day. Go to school, talk to friends, learn a thing or two, have a surprisingly decent school-provided lunch. And then come home, which should be the best part of the day for any student, but not for him. The word “home” didn’t mean much to him. In truth, it never really had.
As he poured the boiling water over the cup of noodles, he could hear the sound of his phone going nuts with vibrations in his bedroom. Probably as a result of his friends posting pictures in their group chat of themselves out drinking, like they seemed to do almost every Friday. They had invited Lucas as well, they always did. They had even offered to pay for any food or alcohol he might want, knowing how poor he was. But like always, he declined. After all, who wants to be that one guy always mooching off his friends?
Lucas glanced at the clock, noting that it was only 7 PM. Could they really be partying this early? Perhaps the vibrations were caused by someone trying to reach him? But who? His friends knew he wasn’t coming, and his family… Well, that was unlikely.
Nevertheless, he brought his cup of noodles with him as he went to have a look at his phone. It had stopped vibrating for the time being, and as he unlocked it, it was made blatantly clear why, to his great distress. Three missed calls. Four text messages. All from the same person: His mother.
The notifications weren’t from a couple of minutes ago, like the vibrations had suggested. They were from an hour to thirty minutes ago, and had been queued up while his phone was turned off. Without even reading the text messages, he knew that something had happened. The last time he had spoken to his mother was more than half a year ago, and they hadn’t exactly left off on good terms.
With a gulp and a bead of sweat running down his temple, he set the cup of noodles down on his nightstand and read the messages in the order they had been sent.
Lucas, please answer! I need to talk to you NOW!!”
I understand if you’re still mad at me, but this is important!
It’s about Rebecca, she’s coming over to see you!
Call me as soon as you can, alright sweetie? Love you...
Lucas stared open-mouthed at the messages for a moment, in complete disbelief to what he was reading. “No, no, no, no, no!” he squeaked to himself. He started pacing around in his room, with his free hand pulling his own hair in panic. This has to be a joke he thought. Please, let this be a joke! Merely reading the name “Rebecca” was enough to practically induce a panic attack for him.
With shaking fingers, he searched through the contact list on his display, clicked on the little phone symbol next to his mother’s number and brought the device up to his ear. “Pick the fuck up, come on…” he mumbled, struggling to keep his breathing at a relaxed pace, listening to the stress-inducing beeps of the ringing tone.
The answer came after only a few seconds, but to Lucas they felt like an eternity. “Hello, Lucas?” he heard his mother say.
“What’s going on, mom?” he pressed impatiently.
”I couldn’t stop her, Lucas, I’m sorry…”
“What the fuck are you talking about?! Why is she visiting me?!”
”She’s…” his mother began, after which a painful silence followed.
“She’s what?!” Lucas shouted back.
”She found out that I helped you move, and that you and I have stayed in touch… I tried to talk her out of it, but she was adamant about visiting you...”
Lucas let out a sigh and covered his eyes with his hand, trying his best to calm down despite the dire situation he was facing. Suddenly, the thought of spending the weekend alone with his textbooks didn’t seem too bad. But now, that was all in shambles, and there was nothing he could do about it.
“How did she get my address?” he asked, his tone as collected as he could muster.
“I… I gave it to her.”
“Jesus christ, mom…”
“I was scared, alright?” his mother whimpered in response. Though in all honesty, Lucas couldn’t blame her. After all, resorting to violence wasn’t out of the question when it came to Rebecca.
“Well, what does she want from me? Is she gonna... hurt me?”
”Of course not!” his mother assured him. ”She would never harm you, you know that.”
“I hope you’re right… When will she be here, anyway?”
His mother went quiet for a second, breaking out in a stumble as she looked for words. “Ah, well… she, um… she took my car, so… any minute now…”
Lucas couldn’t stop himself from chuckling faintly in disbelief. She took the car, he thought to himself. Of course she fucking did. This was getting worse and worse.
“Well, I better get going then,” he said, eager to prepare himself in any way he could for the imminent visit.
“Alright... Call me later, okay? Oh, and… I’m sorry Lucas, I…” Her words came to a halt, but the despair in her voice was palpable.
“... What?”
“Nothing… I love you, sweetie.”

Silence crept through his apartment once again. Lucas remained in the middle of his living room, his phone still held against his ear as he pondered what that last part of the call was about, and how to deal with his “guest”. But mere seconds later, as if right on cue, he heard the sound of his front door being unlocked. He froze in place as he watched the door knob turn around, realizing right then and there what an idiot he was for thinking that he would be notified of her arrival with a ring of his doorbell, or just a knock for that matter. It seemed that his mother had given away more than just the address to his apartment.
The door swung open, slowly. Little by little, Lucas’ anxiety gave way to pure fear as the dark silhouette standing outside his apartment was lit up by the light from his living room. Her tall figure, slender and athletic build, arms covered in numerous scars, and her trademark beautiful blonde hair styled into a mohawk Dutch braid that flowed out in a ponytail.
The girl cast Lucas a judgmental gaze, eyeing him from head to toe. “Long time no see, big bro,” she suddenly said, almost completely without emotion, aside from what seemed like a tad of hostility.
“R-Rebecca…” Lucas stammered, his lip quivering as he spoke. “I… You… What are you doing he—”
“Shut up,” she commanded. “You know damn well why I’m here. We have a lot to talk about, you and I.”
“Listen, Rebecca, I—”
“I said shut the fuck up!” No sooner had the words left her mouth than she began slowly walking towards her brother. “I’ll give you one chance to explain everything that’s been going on during the past year. All of the things that you and mom have been talking about behind my back. I want to hear it all. Now.”
Lucas was practically shaking as Rebecca got closer and closer to him. She was as intimidating as ever, and from having seen what she was capable of, it was perfectly reasonable to fear her. He knew that if he didn’t play his cards right he might end up like his father did all those years ago. Not that Lucas was in any way similar to that abusive piece of shit, but whether or not Rebecca recognized that remained to be discovered.
“Alright, I’ll… I’ll tell you everything. Just promise you’ll try to understand, okay?” Now face to face with her, he could clearly see the two big scars that tarnished her nevertheless pretty features. One of them ran diagonally across her left eyebrow and continued over a portion of her forehead, while the other was a vertical line between her upper lip and the right side of her nose.
Other than the ominous, stern expression on her scarred face, his one year younger sister’s six foot one frame loomed over his half-foot shorter one, requiring him every bit of mental fortitude he possessed just to speak to her in a calm manner. As for her however, calmness had never exactly been her forte, so his expectations regarding where this conversation would end up were understandably low.
“Whatever,” she muttered, crossing her arms under her perky breasts, lifting them up slightly and distorting the black skull depicted on her white tank top. “Talk.”
“I-I’m not sure where to start…”
“You can start by telling me why you left without saying anything.”
Lucas gulped. “... It was mom’s decision. She wanted me to leave.”
“Uh-huh,” Rebecca replied nonchalantly. “And why did she want that?”
“Because…” he began, looking down at the floor, yet still feeling his sister’s stare burn holes in him. “... She wanted me to be safe…”
“Safe from what? Me?”
“Well… yes,” Lucas admitted, mentally preparing himself for a potential violent outburst directed at him.
Rebecca clenched her teeth in anger, and the vein appearing on her forehead seemed almost ready to pop. “That fucking bitch should have known that you are the one person I would never hurt. Up until now, at least.”
Lucas looked up at her, the fear on his face increased tenfold. “Are… are you gonna hurt me now?” he asked, his tone low and meek.
“Depends. Are you gonna side with mom, like you did in the past? Or are you gonna side with me?”
“Please, Rebecca… Why are you like this…?”
“You know damn well why I’m like this,” she scoffed. “But you’ll never understand what it’s like to be me. You’ll never understand how it feels to have a father who hates you just because of the way you were born. And to have a mother who just sits there without giving a fuck.”
“She was afraid! We were all afraid of dad, there was nothing she could do! She…” He had to pause in an attempt to hold back the tears threatening to stream down his cheeks. There were so many things he wanted to tell her, yet none of them seemed likely to make her calm down. Perhaps her mother’s feelings were the most important thing. “She loved you, sis… I bet she still does.”
Rebecca eyed him silently for a moment, before breaking the quiet with something unexpected. “Do you love me, big bro?”
Stunned by the sudden inquiry, Lucas stared right back into her eyes, slowly processing her question and subsequently his answer to it. “O-of course I do, Rebecca!” he finally managed to squeak.
“You hesitated,” she muttered in response. “I should have known. You’re just like mom and dad. I’m nothing but a monster to you… And it’s all because of this fucking thing!” Suddenly, she grabbed her crotch, causing a jaw-droppingly large bulge to be made visible within her denim shorts.
Lucas’ eyes were immediately drawn to it through sheer fascination. It had been several years since he had seen his sister naked, but the thought that it could have grown so big since then was baffling. It was almost freakish. That is certainly how their father would have described it at least. Perhaps even as a “curse”.
Born with the body of a female but with the genitalia of a male, Rebecca was certainly an odd being. But that wasn’t the only thing that stood out about her. Her parents and older brother were all short, with rounded facial features and dark hair, almost to the point of it being pitch-black. Rebecca on the other hand was the polar opposite, tall, a narrow face and nose, and with bright-blonde hair. From whom of their ancestors she had inherited her looks was a mystery, but she was indeed 100% blood-related, much to her father’s dismay.
During their childhood, Lucas and Rebecca spent a lot of time together, with the former doing everything in his power to keep his sister happy in spite of how their parents treated her. He was the only one who was able to make her smile in difficult times, and they loved each other dearly. But his love for her wasn’t enough to save her from what she would eventually become.
At the age of 13, the effects of the abuse had begun manifesting, and the way she was treated only worsened as she shot up in height during puberty. She took up boxing as a way of venting her frustration and anger, but the anger only built up as she kept training. The sweet and kind little sister Lucas had known previously was slowly being transformed into something else.
At 16, when her father had one of his far too common outbursts directed at her, she decided that she had had enough. And as it turns out, it’s a rather bad idea to go after someone who not only towers over you by half a foot and outweighs you by a significant amount, but also happens to be a skilled boxer. Needless to say, after her father returned from the hospital a few weeks later, he never bothered her again. In fact, his shame and hatred for his daughter brought him so far as to leave the family entirely. Though frankly, nobody cried when he left. Their mother was devastated, not because of her husband leaving, but rather from the messed up situation they now found themselves in, and from what her daughter had become.
And from that moment on, Rebecca was the one in charge. Her mother was as meek and spineless as ever, just like with her husband, and allowed her daughter to take over their home and do whatever she pleased with it. Without their mother even realizing it, Rebecca had held a grudge against her for many years, for all those times she had sat in the corner during her husband’s abusive episodes. Furthermore, Lucas, the one person she had always depended on, was becoming increasingly distant, for reasons she couldn’t fathom. The thought that he might oppose her rebellion didn’t even occur to her.
“I see the way you look at it,” Rebecca growled, causing Lucas’ gaze to shift from her bulge to her eyes that were narrowed in anger. “You think it’s disgusting, don’t you?”
“N-no, I—”
“Maybe I should give you the same treatment I gave to mom,” she interrupted, placing both hands on her hips. “That’ll make you get used to it.”
Lucas stared at her curiously, praying that she didn’t mean what he thought she meant. “... What treatment?”
An evil smile formed on her lips. “I forced her to suck me off,” she said, clearly amused by the thought. “Pried her mouth open, shoved my cock down her throat and made her swallow my fat load. Several times, in fact… Fuck, I’m getting horny just thinking about it.”
“You raped her?!” Lucas exclaimed, almost threateningly taking a step closer to his sister but quickly deciding that it was a bad idea.
“Yup,” Rebecca stated casually. “I raped my own mother. And she deserved it.” The smirk on her face suddenly died out, replaced with a death stare right into Lucas’ eyes. “I’m thinking you might too.”
Any sympathy for his mother was quickly replaced with fear for his own safety. “Rebecca, please…” he begged and took a step back, but there wasn’t a trace of wavering on his little sister’s face.
“You left me, Lucas. I thought you’d always have my back, but you threw away our relationship.” She followed Lucas as he continued to walk backwards, feeling a stirring in her shorts that was getting difficult to ignore. “I’ve made up my mind, so get on your knees. Right now.”
“Rebecca, I’m begging you,” Lucas said with tears starting to form in his eyes while he held his hands up in what looked like a half-assed attempt at keeping his sister away from him. “If you do this, there is no going back...”
Rebecca scoffed, unaffected by her brother’s pleas. ”I have nothing to go back to anyway. You and mom made sure of that. But if you’re anything like her, you’ll end up enjoying it before long. Now, this is the last time I will say this. Get. On. Your. Knees.”
In that very moment, Lucas’ whole world came crashing down. He could feel his warm tears begin to run down his face as he now came to realize that there was no escape. If he tried to fight back, his skinny, short build would without a doubt prove to be no match for Rebecca’s tall and athletic one, and running away was out of the question for the same reason. Indeed, there were only two outcomes as far as he could tell: Submit to her big, fat girl-cock, or get beaten into a bloody pulp. Both options seemed equally awful to him, but one of them at least had the benefit of satisfying his mentally deranged little sister. Hopefully she would leave him alone after.
With a gulp, Lucas wiped away his tears and slowly kneeled on the floor, putting his face at level with Rebecca’s crotch. Though his vision was still drenched in constantly flowing tears, he could see a sadistic and satisfied grin on her face, one that clearly signaled that she was victorious. It seemed like no matter what the circumstances or where she went, she would always be in charge.
She began unzipping her shorts while closing the remaining distance between them with a determined step. “Wise choice, big bro,” she said in a mocking tone. “Let’s see if you’re as good as mom at sucking cock.”
Lucas let out a deep sigh, trying his hardest to come to terms with the task at hand. “Will you leave me alone afterwards…?”
“Depends on whether or not you do a good job.” She pulled her shorts down half way down her thighs but left her black panties on. “Come on, bro. Get it out of there and give it a nice sloppy kiss, won’t you?”
Lucas stared at it for a moment, practically stunned by just how filled out her panties were. Not that panties were made to hold penises in the first place, but this was just ridiculous. He could see almost every detail of her cock through the fabric, its semi-hard length bent to the side inside its tight confines, the big, round balls almost spilling out of the leg openings, and the thick base of her cock visible above the waistband.
Sniffling a final time before swallowing back his crying, he reached out with both hands, grabbing the sides of his sister’s panties and began slowly pulling them down. Little by little, the small part of her cock that had been visible at the base turned into inch after inch of thick, veiny cock-meat, throbbing hard against the fabric of the panties that were slowly sliding off of it. Lucas’ eyes were practically glued to it, in part because he wanted to prepare himself for when it sprung free, but also because of sheer curiosity of how big that thing had grown over the years.
And then, like a loaded spring it flopped out, bobbing up and down for a moment before becoming still. Although perhaps “still” was the wrong word for it, seeing as it was throbbing so hard you’d think Rebecca had been edging for hours. As for its size, well, let’s just say Lucas’ expectations were blown out of the water, and he had set the bar pretty damn high. He ran his gaze across the vein-ridden length, trying to estimate its length. It was closer to a foot than half a foot, that much was certain.
“I know you’re getting turned on, Lucas, but I’m getting impatient,” he heard Rebecca purr above him. “Less staring, more sucking.”
“I-I’m not getting turned on!” he protested, averting his eyes after an embarrassingly long time of inspecting his sister’s genitals, feeling a wave of heat wash over his reddening cheeks.
Rebecca chuckled. “You’ve always been a bad liar, big bro. But regardless, you better get to work now. I wanna see how you compare to mom.”
Lucas could virtually hear his heart pounding as he cast a glance out of the corner of his eye at that massive, protruding thing inches from his face. He was unsure of what made a blowjob good, considering that it most likely differed from person to person, but surely there had to be some basic procedure, right? He himself had never received a blowjob before, but he could still imagine the things he would have enjoyed having done to him. Maybe he could just apply those same things to his sister?
Well, there certainly wasn’t a point in dragging out any more, lest Rebecca become even more irritated. Wiping the beads of sweat running down his face with one hand, he grabbed the base of her shaft with the other and decided to just get it over with. He could feel the heat of it starting to spread into his palm and a slight musky scent coming off of the tip that was now dangerously close to his face, as he slowly leaned in to initiate his act of forbidden “love”. He closed his eyes just as his lips came into contact with her thick glans, giving it a slow, overly sensual kiss, all in the hopes of meeting his sister’s expectations.
But her complaints came almost immediately. “Oh no, keep your eyes open, big bro,” she instructed, giving him a couple of light slaps in the face. “I want you to only look at my cock. Burn the image into your brain while you worship it.”
Lucas felt a pang of anger stir up inside him, being humiliated like this by his own little sister. But nevertheless, his facial expression remained the same as before, timid and submissive, just the way he knew she wanted it. With his eyes open, he resumed his “worshipping”, planting another kiss on the tip, then another few ones along its length all the way down to where he was gripping it.
He tried to picture himself getting sucked off as a way of planning his next move, though it wasn’t exactly easy when his brain was busy taking in the view of a cock that not only belonged to his sister, but was also a lot bigger than his own. It probably wasn’t a good idea to just keep kissing it however; even he knew better than to test Rebecca’s patience like that.
Hesitatingly, he parted his lips and let his tongue escape his mouth, giving a wet lick against the smooth, warm shaft, feeling the slightly salty taste hit his tongue. Just like he had worked his way down while kissing it, he licked again and again while moving his mouth back to the tip, where it all culminated in a long, drawn out slather with his whole tongue against the precum-leaking piss-hole, taking in the sticky fluid into his mouth and swallowing reluctantly.
“Okay, okay, not bad,” Rebecca approved. “Keep going. Let’s see if you have what it takes to beat mom.”
He could certainly do without the thought of his mom performing fellatio. It was hard enough being forced to run his tongue over his sister’s cock, and with some concentration he might even have been able to imagine it being a dildo or something, but with the constant remarks he had to endure, he couldn’t even begin to shake the feeling of shame from what he was doing.
Any visible cue of her brother’s disapproval was lost on Rebecca, not that they were particularly noticeable anyway. To her, it almost looked as if he was genuinely enjoying it rather than just bearing with it. His entire face was flushed a deep red, and his eyes that she had commanded him to fixate on her fat cock were seductively half-closed and still slightly teary from before.
He was actually kind of pretty like that. Then again, he had always been pretty in her eyes, ever since he took care of her as a child, but now he had blossomed into a handsome young man, one that took after their mother in many aspects. He had the same pretty, brown eyes, full and rather bushy eyebrows, and their family’s signature button nose, which was a feature that Rebecca always wished she would have inherited herself. Not that she ever complained about her looks, gorgeous as she was. Perhaps it was just a subconscious wish to be more like her brother, like she had wanted when they were growing up together.
Without needing to give him any further instructions, Lucas was already moving on to giving his focus to the tip of her cock, turning his head to the side so he could lick along the side of her fat mushroom tip with his entire tongue. On the left side first, then turning his head to do the same on the right, then underneath it, licking all the way from the frenulum and past her slit, drawing out a perverted moan of pleasure from Rebecca.
“You’re pretty good at this, big bro…” she purred, running her hand through his hair to pull back the dark brown strands that had covered his beautiful eyes. “But your tongue isn’t gonna be enough. Let me see you wrap those pretty lips around it, baby.”
Whether or not Rebecca saw Lucas as more than just a brother was unclear at this point. Baby, he thought to himself, trying not to visibly cringe while he hesitatingly opened his mouth to take her thick glans inside. He had to open up quite wide to let the phallic intruder in all the way, but once he did, he wasted no time in closing his lips tightly around the shaft, just past the rim of the head, which he then began sucking on like it was a lollipop.
“Mm… Yes, baby, just like that…” he heard his sister moan from above him, her hand continuing to gently run his hair between her fingers.
Hearing her moaning filled him with both disgust and a sense of accomplishment. The thought of her actually enjoying having her older brother suck her cock was… vile to say the least. But it also meant he was on the right track, and the faster this was all over, the better.
In an attempt to mimic what he had observed from various pornos he had watched in his days, he decided to kick it up a notch, grabbing her cock with both hands, one around the base and one around the middle of her shaft, using them to jerk her off while his lips and tongue kept on sucking and licking the tip. He knew what his increased effort would inevitably result in, but there was no way around it. As long as he was prepared for when it happened, he could at least make sure not to get an unwanted mouthful. Although, if the size of her balls was in any way an indicator for how much spunk she produced, the end result would probably be quite messy regardless of where it ended up.
“Damn…” Rebecca swooned, her breath heavy and her legs trembling from pleasure. “Looks like sucking cock is a skill that runs in the family...”
Lucas glanced up at her, giving her a look that walked a line between fear and anger. However, before he had the chance to remember to keep his eyes on her cock like she had instructed, he could clearly see the expression on her face shift from a content smirk to one of surprise. Shock, even.
“Oh fuck, Lucas, don’t look at me like that...” she gasped, biting her lip and taking a deep breath. “You’re gonna make me cum… Oh, shit…”
Although taken aback from the fact that it had taken way less time than he had anticipated, Lucas needed no further warning. The moment he felt her cock begin to twitch in his mouth he immediately withdrew his head and let go of her shaft. He wanted nothing more than to steer completely clear of Rebecca’s line of fire, but he knew that it would piss her off. Indeed, he had to face it head on.
Grabbing the base of her cock, Rebecca let out a loud moan that could almost be classified as a delirious scream. Her veiny shaft throbbed hard as it practically erupted with cum, making her first rope shoot out in an arc that painted a line diagonally across Lucas’ face, from chin to hairline. The next bursts came in a more controlled manner, hitting him on his closed lips, nose and eyelids, quickly making his pretty features indistinguishable under a thick layer of white, gooey girl-cum. Mouth agape and eyes squinting in pleasure as her long-winded orgasm continued, Rebecca aimed her cock as carefully as she could, making sure to give her older brother a complete facial and letting the last few shots land in his dark brown hair.
“God fucking damn it, big bro…” Rebecca panted, admiring her handiwork with a lick of her lips while her cock continued to drip cum. “It’s like you’re trying to make me fall in love with you or something…”
With his mouth glued shut, Lucas had no choice but to breathe through his nose, forced to take in the smell of his little sister’s stinky cum that he was now wearing like a second skin. He could feel it hanging off of his chin, like thick, sticky strings that were slowly dripping off, staining his black t-shirt, while some of it simply flowed down his neck and unfortunately continued down his chest.
His cheeks were burning up, in part due to the sheer heat of Rebecca’s seed, but more so because of his incredible shame and disgust over what had just taken place. This was truly the final nail in the coffin. The sweet, albeit troubled little sister he had loved so dearly all those years back was gone, replaced with a cruel tormentor who enjoyed the suffering of others.
“Can you please leave me alone now…?” Lucas mumbled, getting an unavoidable taste of his sister’s cum as he opened his mouth.
Rebecca looked down at his doe-eyed expression with a grin, wiping away a few sweaty strands of blonde hair that had fallen in front of her face. “Hell no. You think I’m satisfied after cumming only once?”
“... You’ve got to be kidding me…”
“Nope,” she chirped, putting her hands on her hips. “Girls like me require a bit more than that, especially grade-A specimens like myself. Besides, it’s my turn to do the work.”
Lucas immediately realized the ominousness in her words. “... What does that mean?”
“You’ll see after you get me hard again,” she said, tauntingly swinging her softening cock from left to right. “Chop-chop! Get to it!”
By this point, Lucas was practically dead inside. Was there even a point in resisting anymore? He had already been sullied after all, and getting her off one more time almost seemed like a small price to pay to have her finally leave him alone.
Without a word, Lucas once again grabbed his sister’s cock and promptly began mindlessly jerking it, difficult as it might be in its flaccid state. Even now, the weight and volume of it easily outshone that of his own, and his wasn’t even particularly small. But at this point it no longer bothered him. There was only one thought on his mind: Making Rebecca cum again.
“You’re gonna have to do more than that,” she hinted, giving Lucas a strange little smile.
He looked up at her, past her perky tits that jutted out slightly, noticing her giving him a strange little smile. “You mean… with my mouth?”
“Who knows. Try thinking outside the box.”
Outside the box?” he thought, scanning her genitals in confusion. Then it hit him. Her balls. In the face of her thick cock he had almost forgotten about them, even though he realized that they were perfectly visible now, no longer held back by her flimsy panties. Hanging low and heavy, they had remained completely untouched during this whole ordeal. Perhaps that had to change?
Using both hands, he gave them a light touch with the tips of his fingers, immediately noticing the heat radiating off their smooth surface. Carefully, he began rolling them between his fingers, massaging them with what he thought was enough force to stimulate without going too far. After all, the last thing he wanted was to hurt Rebecca, knowing that she could retaliate with far more force. But then again, taking her size and virility into account, it wouldn’t have been surprising if her testicles were a lot more robust than the average person’s.
“Hmmm, not enough,” said Rebecca, her facial expression blank and unimpressed.
Bitch, Lucas thought to himself, as he hesitatingly parted his lips to let the tip of her flaccid cock in once again, while continuing to gently rub her balls. Several inches sunk into his mouth without any problem whatsoever, all thanks to it not being in its massive, erect state. He wrapped his lips tightly around its girth, feeling the spongy texture give way as he sucked it with all his might, desperate to get it hard.
For two or so minutes he went at it, sucking Rebecca’s soft cock that refused to grow even an inch longer and stiffer, while his hands tightly gripped her big balls, massaging them, yanking them, squeezing them, almost like you would a cow’s udder. Nothing was working. Looking up at her only earned him a disappointed look on her face, almost making him angry over receiving zero appreciation for what he was doing.
For the time being, he popped her cock out of her mouth. “Just… tell me what you want me to do…” he said, defeated and desperate.
“Come on, Lucas,” Rebecca chided, rolling her eyes. “You know the basics of the male reproductive system, don’t you?”
Lucas stared blankly at her. “... What about it?”
“Gee, I don’t know. If only there was a part of the male body that could be stimulated for added pleasure… Like a certain... ‘spot’ somewhere…” A downright evil smile spread across her face as she spoke, and the look on her brother’s face as the realization slowly set in was quite possibly the best thing ever.
“You don’t mean… what I think you mean… right?”
“What do you think I mean?” Rebecca mocked, knowing damn well what was going through her brother’s head.
“Please, Rebecca…” he begged. “I can’t do something like that… You’re going too far!”
In an instant, the look on Rebecca’s face changed from amused to threatening, as she leaned over almost 90 degrees, putting her face right in front of Lucas’. “Don’t test my patience, Lucas. If I don’t feel your finger rubbing my prostate within the next minute, I’ll break it off of your hand.”
Lucas clenched his teeth, once again frustrated by his inability to talk back to his sister. This time, he was seriously contemplating running away, but thankfully his sense of reason hadn’t left him completely. Even if he were to escape, Rebecca could just wait him out, since there was nowhere for him to go without letting others know what he had been through. Furthermore, despite everything that she had done, he knew he couldn’t bring himself to contact the police. They were still family after all.
“Clock’s ticking,” Rebecca prodded.
“I need lube.”
Rebecca gave him a light chuckle. “As far as I can see, there’s lube all over your face.”
A moment of silent staring into each other’s eyes passed, before Lucas reluctantly used his right index finger to scoop up some of the sticky seed that coated his cheeks. He made sure to cover every part of it, all the way down to his third knuckle, to make sure that there would be as little resistance as possible. Once ready he took a deep breath, and with his left hand he lifted Rebecca’s fat ballsack up, allowing for easier access to her anus.
“That’s it…” she cooed, jutting her hips forward to help Lucas with his task. “Don’t be shy…”
Lucas almost broke out into a cold sweat as he watched his own little sister use her hands to spread her buttcheeks and present her puckered hole to him. It didn’t look gross or anything, it was actually quite pleasing to the eye, smooth-shaven and clean, with a deep pinkish color. To Lucas’ shame it was almost a bit hot, or at least it would have been, had it been someone other than his sister. Perhaps it was precisely that realization that was causing him to panic.
Nevertheless, he reached out with his trembling hand, slowly closing the distance between it and Rebecca’s asshole. Here goes nothing... he thought to himself, closing his eyes at the same moment his finger finally connected. A shudder went through his body as he felt the wrinkled surface against his finger, but with a deep breath and a mind that was slowly getting fueled with determination to get it over with, he started pushing.
“Oh!” Rebecca exclaimed, the ring of her anus tightening as Lucas’ finger penetrated her. “God damnit, big bro… You didn’t even hesitate…” With a bite of her lip, she gave her brother a look of admiration, noticing how adorable he looked with that little frown and flushed cheeks. She could feel him push deeper and deeper, sending a tingling sensation through her core. ”Mmm, yes… Nice and deep, just like that…”
“... Where is it?” Lucas asked awkwardly, as more and more of his finger was swallowed up by the warm depths of Rebecca’s asshole.
“Mm… Right there… Just… bend your finger and start rubbing…”
“Like this?” Without holding back, he did just as he had been told, grinding the tip of his finger against the wall of her rectum, and sure enough he felt a little bump that could be nothing other than what he was looking for.
“Ah!” she moaned, feeling her legs almost give out from the sudden pleasure. “Just like that! Oh… fuck! Keep going!”
Finally, something was working. With a twitch, Rebecca’s musky cock was beginning to come back to life, right in front of Lucas’ awestruck face. Its already huge girth was slowly becoming even thicker, as it ballooned up and rose into the air, reaching a position where it pointed straight out from her body before long.
“Suck it, baby…” ordered Rebecca, though in her aroused state it sounded almost as if she was begging him.
“Okay…” It was almost with a certain eagerness that Lucas opened his mouth wide and leaned in to take her cock inside. Within an instant he could feel a big wad of precum spilling onto his tongue, which, if it weren’t for his desperation to get his sister off, would probably have had him gagging. Now, however, he simply returned to doing what he had attempted before, sliding his lips up and down the still bearable thickness of her cock, knowing that it would soon become a lot more difficult to fit her ever growing shaft inside his mouth.
“Ooooh, just a little more… Keep rubbing…”
Lucas picked up his pace, sucking with such force that it almost seemed as though he was trying to sever Rebecca’s dick in half. With his finger still stuck in her ass, his “rubbing” could be more accurately described as “pummeling”, as he used all his force to press down on her prostate like he was trying to milk semen straight out of it, and the loud moans from above confirmed that his rough treatment was appreciated. Almost instantaneously as a result of his massage however, the cock that was firmly lodged in his mouth became as hard and rigid as steel.
Every neuron in Lucas’ brain told him to retreat, and at that point he knew better than to dismiss the warning. The tight grip with which his lips were wrapped around Rebecca’s cock subsided almost completely, before he took a deep breath through his nose and slid back, hoping for a short breather before he went in for another blowjob.
But Rebecca, who was starting to enjoy herself for real, would have none of it. “Oh, no, you don’t!” she growled, grabbing the back of Lucas’ head and forcing him back around her cock. “I told you, I’m in charge this time! You don’t get any breaks!”
“Mmm!” Lucas whined in panic, his eyes going wide as he felt his entire mouth get filled by thick girl-meat.
“S-stop complaining…!” Rebecca stammered, drool starting to leak out of her mouth. “Ugh… Damn, your mouth was fucking made for this…” Paying no heed to his safety, she held him firmly in place for a moment, before starting to slide his head back and forth, a little deeper each consecutive time, until she could feel the back of her brother’s throat pressing against the sensitive tip of her cock.
Lucas let out a loud gag that Rebecca seemed to ignore, followed by another one as she slammed into him even harder, quickly beginning an unrelenting onslaught of thrusts. Time and time again, he could feel the boiling sensation of stomach acid rising in his throat, while its entrance continuously tightened up to keep the phallic intruder out.
A painful realization slowly set in. The more he resisted, the more painful it would be, not to mention the more likely it was for him to violently throw up all over the place. There was no telling how Rebecca would react to that. With anger? Amusement? Whatever it might be, Lucas wasn’t keen on finding out.
“Fucking… relax… your throat!” she snarled, her words interwoven with her thrusts. “Take it like a man!”
At that point, her commands weren’t even needed. The continuous plunging into the entrance of Lucas’ throat and his constant gagging had him gasping for air, bringing him closer to blacking out by the second. He could feel his tonsils start to give way to the cock that so desperately wanted access to his esophagus, and he knew that it was pointless to do anything other than let it happen.
At last, his eyes rolled back into his skull as the tip of his sister’s cock breached into his throat. He didn’t even gag as it happened, almost as if his brain had turned off the reflex entirely, allowing him to be used as a cock-sleeve.
“Oh my god…” Rebecca swooned, practically frothing at the mouth. “I fucking love you, big bro…” With one long, drawn out push, she sunk her cock deeper and deeper into him, feeling the walls of his wet throat hugging her shaft tightly, rapidly sending waves of pleasure through her entire being and almost causing her to orgasm right then and there.
Lucas gurgled along the length of her meat as drool kept leaking from his mouth uncontrollably. His strength was completely drained from him, and even as Rebecca began humping his face in earnest, milking her cock with his tight insides and slapping her big nuts against his chin, he merely let his arms dangle above the floor. There was no escape for him, not with his sister's hands gripping his skull tightly, his dark hair sticking out in tufts between her fingers.
Oddly enough, the violent skull-fucking was bringing him more than pain. The feeling of his throat being filled up and continuously stimulated by Rebecca’s massive tool somehow brought along a strange pleasure, like a full, tingling feeling. Perhaps it was just because he was becoming numb to the pain and therefore experienced the pleasure to a greater degree, but either way, despite his lack of oxygen, it was actually becoming bearable. Almost… enjoyable.
After minutes of vigorous thrusting, Rebecca could finally feel her cock start to pulsate violently within her brother’s throat. “Oh, shit, I’m gonna fucking cum!” she shouted, gritting her teeth and firmly pressing Lucas’ nose against her pubic mound, going balls deep for the first time.
Almost as if she was pissing, her warm cream began spewing down her brother’s throat, deep enough to not even require swallowing. Her balls tightened against her pelvis as they emptied themselves of their seed, getting rid of whatever was left after nutting all over his face.
“Mm, yes, baby…” Rebecca groaned. “Milk your little sister’s cock…”
A faint, muffled spurting could be heard as her searing cum quickly spread within Lucas’ stomach, being deposited straight into it without any resistance whatsoever. It was a mystery how she was able to produce such a volume a second time, each burst of semen feeling like the total volume of a normal person’s. Lucas lost count of how many times Rebecca’s massive cock twitched and released within his throat, but it felt like it lasted for an eternity.
Even as her orgasm slowly diminished, Rebecca still held her brother’s head as far down the length as possible, panting ecstatically with a wide smile on her face. A small dribble of cum still oozed out of her, as her cock, that had so aggressively forced itself down Lucas’ throat, finally calmed down and began to deflate. She cast a glance at him, finally realizing his desperate need for air as she saw his purple face beneath the mask of drying cum.
“Oh shit!” she exclaimed, pulling his head off her cock and letting go of him, causing him to collapse onto the floor, which he promptly began drooling all over. “You, uh… you okay?”
Lucas let out a throaty gurgle as he began gasping for air, staring blankly at the ceiling. He had been humiliated, taken by force in his own home, but despite that, there was only one thought on his mind, one that almost brought him happiness: It was over. There was no doubt in his mind that he had surpassed Rebecca’s expectations, and now, he would claim his freedom.
“Whatever,” Rebecca casually stated, tucking her cock back inside her denim shorts and zipping up her fly. “You did well, Lucas. I think I’ll stay.”
... What?! Lucas thought, feeling his breath get caught in his throat for a short moment as he processed what he had just heard her say. “What… what do you mean…?” he said, his voice raspy and weak, getting up on all fours and directing his timid gaze at Rebecca.
“I mean that I’m moving in with you. That’s why I came here.”
“M-moving in…?” Lucas stammered. “Didn’t you say that you would leave me alone if I did well?”
Rebecca crossed her arms menacingly as she stared at him from above. “That’s not what I said, dumbass. I only said that it depended on whether or not you did a good job. Contrarily, if you had disappointed me, I would have left.” Yeah, fucking right, she thought to herself. As if something so trivial would have caused her to give up. It would merely have encouraged her to teach him how to properly suck dick, which would have been fun in and of itself. But now that she knew what he was capable of, there was no way she wasn’t going to take advantage of it.
“But… this is my apartment!” he protested. “You can’t just… do whatever you want!”
Rebecca chuckled. “Cut the shit. I know mom paid for all of this, and that she’s the owner of the apartment. Well, used to be, anyway.”
A feeling of dread hit Lucas like a truck. “... What do you mean ‘used to be’?”
Giving him a cryptic smirk, Rebecca spun around and headed for the front door. She opened it and bent down, picking up two large suitcases that she had sneakily left in the hallway before. With two loud thuds, she casually threw them onto Lucas’ living room floor, closed the door behind herself and made her way over to one of the cases, before opening up one of the small compartments on the side and retrieving a bundle of papers within a plastic sheet protector.
To Lucas it felt like time stopped as he watched her fiddle with the papers, while he sat there on the floor, hoping, praying that his suspicion would be deflated. But sure enough, the first sheet in the bundle that Rebecca presented to him before long looked just like the one he had watched his mother sign roughly a year earlier. A contract regarding ownership of the apartment. The very apartment that he had called his, that had come to be the only place he could call home, despite the short period of time that he had lived there. But now, the signature written in the several sheets of paper within the bundle wasn’t his mother’s. It was his sister’s.
Overcome with a sense of defeat, Lucas glanced up at her, at the obnoxious, smug grin that tainted her scarred, but otherwise pretty face. He couldn’t even be bothered to flinch as she suddenly reached out with one hand and gently grabbed him by the hair, pulling his head back slightly so that they were facing each other directly.
Rebecca bit her lip as she stared into Lucas’ brown eyes, before uttering the final, humiliating blow to his pride. “Hope you’re looking forward to being my bitch.”
