A Sullied Diamond

Summary:

It's New Years Eve, and Dia is supposed to be preparing to return home for her birthday. But against her better judgement, she instead finds herself at the suite belonging to her university's notorious playboy. Surely she's here to give him a piece of her mind, right?

Happy Birthday Dia.

Notes:

I just wanted to write Dia getting fucked silly for her birthday.
You all can hate me for this.

Work Text:

Stepping out of an elevator, Dia begrudgingly dragged her feet towards the nearby door. She didn’t want to be here, as she would much rather spend her free time tying up loose ends before returning home to celebrate both the new year and her birthday with her family. But after being summoned through text message earlier, she found it difficult to say no.

The sole resident of this luxury apartment was someone she detested, as their personality was complete and utter garbage, but no matter how hard she tried to distance herself from them, Dia found herself drawn back here time and time again. It frustrated her to no end, as she came here of her own volition.

Dreading the moment the penthouse’s doors opened, Dia could hear footsteps coming from the other side. She debated making a run for the elevator, to get out of here before she embarrassed herself any further, but her legs wouldn’t budge, even if she wanted them to. She knew that by coming here, that she wouldn’t be leaving until the next day.

Dia’s stomach sank as the door opened, revealing a tall, wellbuilt male wearing nothing but a bath towel around his waist. His tanned skin was glistening wet, evidence that he had just stepped out of the shower. He was your textbook playboy, a notorious womanizer who lived off of his family’s wealth.

Grinning as he rested one of his toned arms against the doorframe, the ladies’ man eyed up his guest from head to toe, approving of her outfit. It wasn’t as revealing as he would have liked, but she was dressed up like a prim and proper girl, one who was trying to look conservative yet fashionable.

Shuddering as she could feel her choice in clothes being judged, Dia was about ready to remind him that she isn’t here to impress him, to give him an earful of just how insufferable he was. She wasn't wearing anything special; just a woolen white sweater, and a pair of dark jeans.

“What? Disappointed I’m not dressed up like one of your sluts?” Dia crossed her arms and glared up at the tall playboy, disapproving of both his lifestyle and his personality. She knew very well about his reputation, that he was sleeping around with all kinds of women from their university.

Laughing to himself as he was used to being treated so harshly by the strict girl, he ran his fingers through his wet blonde hair before straightening himself up. He was in a playful mood, and he wanted to banter with her just a little, “Of course you’d know what I’m into, babe. I guess you really do have the hots for me.”

“E-Excuse me?! Who would ever fall for an inconsiderate philanderer like you?!” Dia’s face turned red as she responded in kind, letting him know just how outrageous he was to even joke about such a thing. She was flustered, and she was already regretting not walking away before he opened the door.

Shrugging his shoulders as he wasn’t even the slightest bit concerned about her insults, the playboy merely stepped closer and placed a hand on one of her shoulders. He was quite smug as he exclaimed, “And yet, you came here as fast as you could. Bet you couldn’t wait to get dicked down, huh?”

Freezing up as she hadn’t expected him to be so direct about it, Dia took a moment to regain her composure before slapping his hand off of her. Brushing her shoulder length hair back into place, she tried to remain dignified as she said, “I-I did no such thing! Why on Earth would I want to be alone with you, Kazuki?”

“Afraid to admit that you’re addicted to my dick, babe? If you didn’t want to be here, then why did you come, huh?” Kazuki loved this back and forth, as he quite enjoyed seeing how worked up the diligent girl could get. He hadn’t blackmailed her, or even made any kind of threats in his text message earlier; he simply asked for her to come visit.

Dia groaned as she begrudgingly gave up for now, as the more time she spent arguing with this thick-headed brute, the less time she would have to prepare for her trip back home. The quicker things were wrapped up here, the sooner she could return to her apartment and pack her belongings.

“Whatever. Let’s just hurry up and get this over with,” Dia made it crystal clear that she didn’t want to prolong her stay here, even if in the past she had always spent the night. She told herself that tonight was going to be different, that she would only waste a couple of hours here at most before leaving.

As she pushed past Kazuki, Dia let out a shriek and jumped when she found herself being slapped on the ass. She stopped to glare disapprovingly at him, only to give up quickly as he gave her a shiteating grin. She couldn’t fathom how anyone could tolerate him, let alone want to spend time with him.

Not bothering to take in the breathtaking view from the windows, Dia had long since seen through the appeal to this penthouse suite. If the person staying here was anyone else, then maybe she would enjoy herself, but as it stands, this place was nothing more than a cesspool.

Entering the bedroom and taking a seat on the edge of the king sized bed, Dia scrunched up her nose as she tried to mentally prepare herself for what was about to occur. The strong, overwhelming smell of sweat and musky semen polluted the air, making her feel as if she had just stepped into a seedbed.

Following behind his temperamental guest, Kazuki casually took a seat beside her and wrapped an arm around her, groping one of her boobs without a care in the world. His guard was down, as he was certain that he wasn’t about to have his face slapped for daring to lay his hand on someone.

“Seriously, you’re the hottest girl at uni, babe. Hard to believe your tits are this big. I bet you used to massage them every day,” Kazuki shamelessly hit on the black-haired beauty, going so far as to accuse her of being a closet pervert. He knew they were real, that she wasn’t the kind to undergo surgery in order to look sexy.

Rolling her eyes as she’s heard all of this countless times before, Dia didn’t even bother to humour him by disputing his accusation. There was no point, as he would just continue to pester her no matter what she said. She bit her lip as she endured having her chest fondled, her cheeks flushed a bright shade of red.

“You’re the worst…” Dia groaned out in disgust, hoping that he would finally get the message and learn that she hated his guts. She’d been trying to get away from him for almost the entire year at this point, and she had yet to succeed. He was like a parasite, and getting rid of him wasn’t easy.

Despite being serious about her studies, and not going to parties like so many university students did, Dia had accepted an invitation from her friends at the beginning of the year to attend a mixer. She had her apprehensions about it, as she wasn’t interested in a relationship, but she went along with it just to be nice.

It started out well at first, but Dia soon found herself being hounded by the playboy, who was persistent about hooking up with her, even if it was just for one night. She tried many times to get rid of him, but her friends egged him on, encouraging Kazuki to not stop until he thawed her frozen heart.

One thing led to another, and Dia mistakenly proposed that she would humour the womanizer for just an hour, that she would willingly go to a love hotel with him in order to get him off of her back. She thought that it would be easy, that he would be satisfied if she pleasured him just the one time, but she was wrong.

Kazuki showed Dia a whole new world, making her experience pleasure beyond her wildest dreams. What was supposed to be a quickie dragged on long into the night, lasting all the way until late in the morning. They only stopped when the hotel staff kicked them out, but they resumed once they arrived at the penthouse.

It was a decision that Dia deeply regretted, as what she intended to be a one night stand transformed into a relationship she wished would hurry up and end. She tried to give the playboy the cold shoulder, to pretend as if nothing ever happened to her, but he was persistent, reminding her of all the fun they had together, and asking for more.

To this day, Dia beat herself up for letting this happen, for allowing some lecherous scum distract her like this. She had tried to ignore him, to pretend as if he didn’t exist, but no matter how hard she tried, she always gave in and accepted his advances, hoping that he would grow bored and leave her alone.

Alarmed as the hand on her breast moved to her face, Dia’s turquoise eyes went wide with disbelief as Kazuki turned her head towards him and stole a kiss. He immediately shoved his tongue into her mouth, entangling it with hers as she tried to push him away. He’d lick the inside of her mouth, savouring her sweet saliva.

As tense as she was to suddenly be kissed by this selfish prick, Dia’s shoulders slumped down as her body remembered just how good it felt to submit to him, how much pleasure awaited her if she let him have his way with her. She hated it, but she found herself reciprocating his advances, exchanging fluids with him.

Dia didn’t even try to resist as he began to unzip her jeans, pulling them slowly down her thick thighs. Her heart was racing as their lips separated, a string of saliva acting as a bridge that connected them. Finding herself being lowered backwards onto the bed, she knew there was no point in trying to delay the inevitable.

She came here despite knowing what would happen, and despite her hatred towards Kazuki, she just couldn’t bring herself to resist. His personality may be terrible, but as a male, there was no denying that he was skilled in the bedroom, that his sexual prowess was something to be feared.

As a female, she was instinctively drawn towards the strong, crude male who taught her what pleasure truly is. Try as she might to fight it, her body yearned for his touch, and she always found herself surrendering to him once they were alone. She hated to admit it, but she wanted him.

Managing to pull his woman’s jeans off, Kazuki tossed them carelessly onto the floor before grabbing her thick thighs and spreading them apart. He grinned from ear to ear as he got a good look at her black, lacy panties, and he couldn’t help but to tease her for it, “Someone came prepared, huh?”

“S-Shut up,” Dia spat back at him, ashamed of herself for willingly changing into lingerie after she received that text message from him. There was no way she could get herself out of this, as any attempts to lie would be all so obvious. She wanted this, and there was no denying that she had gone out of her way to try and impress this lecherous fiend.

Unfazed, Kazuki crawled up the bed and brought his head just inches away from hers, sticking his tongue out. When Dia reciprocated and did the same, he wasted no time in french kissing her, all while he slid one of his hands underneath her panties and inserted two thick fingers into her wet womanhood.

Slick noises filled the air as Kazuki fingered his woman relentlessly, bottoming both of his digits inside of her and curling them upwards to stroke the inner walls. He knew all of her weak spots, and he made sure to remind her of this fact, that he was the first to explore her body, that he had molded her to his taste.

Moaning and bucking her hips upwards, Dia was no longer behaving like the dignified, studious girl everyone knew her as. She was practically begging for the playboy’s touch, acting like his obedient bitch. She could blame him for turning her into a slut as much as she wants, but she secretly enjoyed cutting loose and surrendering herself to her desires.

Pulling his sopping wet fingers out, Kazuki was met with a disapproving groan. As thrilling as it was to have her at his mercy, he decided to remind her of her place by flicking her clitoris, earning himself a high pitched scream as their tongues separated. Laughing at how bestial she sounded, he did it again and again just to listen to that sweet music.

Flopping back down onto the bed as her body twitched from the stinging sensation, Dia felt as if she was on fire, like she was going to suffocate in her clothes. As she laid eyes on that shiteating grin, she felt ashamed of herself for letting such a sleazy prick treat her like she was just a toy.

“You know what to do if you want more,” Kazuki ridiculed her as he sat beside her on the bed, his eyes glued to her heaving chest. He had done this so many times before, not just to Dia, but to other women, both young and old. He couldn’t even begin to count how many he’s slept with, but he knew very well who his favourite was.

Feeling as if she had been read like an open book, Dia begrudgingly climbed to her feet and removed the rest of her clothes. Her matching black underwear sat atop of her jeans and sweater, and while she normally would fold them up to ensure they didn’t crumple, she let it slide for once.

Trying to maintain some level of modesty, Dia placed an arm across her chest, hiding her areola and nipples as best as she could. She could feel the beastly playboy etching her image into his mind, and while it was embarrassing, she was also flattered that he thought so highly of her as a female.

Her breasts were both long and large, comparable to watermelons when they weren’t stuffed inside of a bra. Her waist was tight and slim, but her expansive hips were as wide as her shoulders, making her constantly bump into things in her daily life. Her whole body was erotic, and yet she tried to pretend like it wasn’t.

Unable to find another woman who could even come close to matching the black-haired beauty’s sex appeal, Kazuki licked his lips hungrily as he believed her to be perfect. His groin began to stir as blood flowed through his manhood, and he felt a little impatient as he asked, “Are you just going to stand there?”

Swallowing what was left of her pride, Dia spread her legs and squatted down, standing on her tiptoes with her hands behind her head. She was red in the face as she closed her eyes, trying to pretend like this insufferable playboy wasn’t watching her. Mentally preparing herself for what she was about to do, she began to swing her hips from side to side.

Dia’s breasts jiggled and bounced in tune with the rest of her body as she danced like a slut, the sound of her boobs slapping against her torso echoing throughout the room. Alternating between swinging her hips from side to side, to bucking them back and forth, she was humiliating herself all for the sake of entertaining this philander.

She felt like a complete and utter disgrace, like there was nothing else she could do that was more embarrassing than this, and yet Dia couldn’t stop behaving like a vulgar woman as she danced hypnotically with her tits. Peeking out through one eye, she lost track of what she was doing as she stared in awe at Kazuki’s bare crotch.

Despite seeing him naked far too many times than she would have liked, Dia was always shocked at how well equipped he was. His erection was as long as her forearm, and twice as thick. It was covered in veins that bulged outwards, and the tip was a dark, intimidating shade of red.

Even his testicles were incredible, as they hung between his knees, rivalling cantaloupes in terms of size. They were surprisingly heavy, and were packed full of a surreal amount of jizz. To say that he was on par with the biggest porn stars would be doing him no justice; he was superior, an alpha male that stood far above the rest of his pack.

She couldn’t even begin to think of the amount of times that behemoth of a cock has stirred up her insides, reshaping her until she would only ever be satisfied with the playboy as a mate. She had long since suspended her disbelief about how something so big could fit inside of her, as she’d learned first hand just what it was capable of.

“Someone’s lovestruck. Get your ass over here, babe. Or do you want all of Tokyo to see me fuck you like the whore you are?” Kazuki was stern yet flirty as he laid down the rules, instructing his woman of what was going to happen. She could lay on the bed, or he could lift her up and wreck her pussy in front of the windows.

Feeling weak in the knees as she remembered how thrilling it was to do it while looking out at the city, Dia couldn’t even try and hide her excitement as she shakenly strutted to the bed, crawling onto it as seductively as she could. She was on all fours before the cocky stud, her face close to his hulking manhood.

“You’re so fucking hot. You act like a bitch, but deep down you’re a slut for my dick, aren’t you?” Kazuki spoke nothing but the truth as he degraded her, his smirk widening as he loved that lustful look in her eyes. She was panting like an animal in heat, and he didn’t even have to tell her what to do next.

Embarrassed over being called out like that, Dia puckered her lips and gave the engorged tip a big, affectionate smooch. Rewarded with a coating of precum, she licked it off without any hesitation before opening her mouth wide, and slowly pushing the red glans inside, feeding herself an extra inch every few moments.

“Fuck, I can’t hold back anymore!” Kazuki roared out, placing both of his hands on the back of his woman’s head. With control over the situation, he began to slam his hips back and forth, forcing his unfathomably large dick down her throat whether she was prepared for it or not.

Relishing the feeling of how tight her throat was, Kazuki facefucked the studious girl with all of his might, making her choke and gag on his prideful bitch breaker. He loved seeing her glare up at him through her narrow eyes, how she tried to act as if she detested every fibre of his being, as it only fuelled his desire to make her be honest.

Grunting as he quickened his pace, Kazuki could feel a slender tongue attempt to wrap itself around his girthy manhood. It was almost as if Dia was trying to please him, and that thought alone urged him onwards, making him bury her face in his crotch while his nuts slapped repeatedly against her jaw.

“Hope you’re hungry, babe! I’m cumming!” Roaring out at the top of his lungs, Kazuki’s beastly moan drowned out the sound of Dia gulping down ludicrous amounts of semen, choking on it in the process. He was unstoppable as he held her head firmly, ensuring that she had no choice but to swallow his seed.

Dia’s senses were being overwhelmed, as the bitter taste dominated her tongue and mouth, while a strong musky scent invaded her nose, leaving her head a spinning mess as her stomach was pumped full of the playboy’s filthy cum. She wasn’t going to be hungry after this, as this quantity could easily be described as a meal of its own.

She would know; she has drunk jizz through a straw out of glasses, mugs, and even a bucket on multiple occasions.

There was just so much cum that Dia could feel it clinging to the inside of her throat as the monstrous cock was slowly pulled out of her mouth. She could barely breathe, and all she could do was try and gulp down every last drop of this insufferable stud’s load. If she wasted even an ounce, she would be disciplined.

Opening her mouth to showcase that there wasn’t any baby batter left, that she had indeed swallowed it all, Dia wasn’t prepared for a loud belch to erupt from her cum glazed lips. Her turquoise eyes went wide as she realised what she did, and she hung her head in shame as she’d never done anything like this before.

“That was sexy as fuck, babe. You must really like the taste of my jizz, huh? Guess I’ll have to make you a drink or two later,” Kazuki’s monolithic cock twitched with approval as he was blown away at just how disgraceful of a display that was. It was such a massive turn on, and he wanted to see it happen again.

Wearing a vulgar expression on her face, Dia wasn’t sure how to respond to that. She was disgusted with herself for doing something so unladylike, but on the other hand, it was strangely exciting. Not to mention how fulfilling it was to receive praise from the playboy for something so outlandish.

“Show me your fat ass. Now.” Kazuki barked out instructions once more, his erection feeling as if it was as hard as diamonds. He needed some action, and he wanted to plow the black-haired beauty’s rear from behind while wrecking her tight little pussy that belonged to him.

Shakenly complying with his demands, Dia pushed herself up onto all fours, and directed her behind towards him. Gazing back over her shoulder, she could see that he was on his knees, that he was licking his lips with approval. Without being prompted, she reached back and spread her asscheeks apart, revealing her puckered asshole and her wet womanhood.

“You’re leaking like a faucet. You were totally looking forward to this, weren’t you?” Kazuki whistled as he admired how drenched his woman’s pussy was, how it was dripping down between her legs onto the bed sheets. He knew exactly why she came here, even if she refused to be honest with herself.

Shrieking as she felt a firm, strong hand slap one of her asscheeks, Dia wiggled her booty as a response. As she felt the philander grab hold of her tight waist, she knew that there was no delaying the inevitable. She was going to be impaled on this gigantic cock, and she was going to love every second of it.

With skilled precision, Kazuki didn’t even need to properly align himself with the entrance to her vagina as he thrust his hips forward, penetrating her in one fell swoop. He only managed to get half of his hulking erection inside of her before slamming against her cervix, a testament as to just how hung he truly was.

“No matter how many times we do it, you’re still just as tight as a virgin,” Kazuki could feel every nook and cranny of his partner’s womanhood clinging to his girthy manhood, and he was truthful in comparing her to a virgin. He always left her a gaping mess whenever they met up like this, yet somehow her hole returned to being just as tight as ever.

Dia’s mind turned blank every time the playboy knocked on her womb, almost as if he was demanding to be let in. Her face was resting against the bed sheets, drool pouring out the corner of her mouth as she tried to endure the brutal pounding coming from behind. Try as she might, she couldn’t prevent herself from squirting every time she climaxed.

“Your pussy is so fucking weak, babe. You cum every time I slam against your womb. Don’t try and deny it. I can feel you tightening up,” Kazuki mocked her, reminding her of just who was in charge here, and how she had no chance of ever coming out on top. He was just toying with her, preparing for the grand moment in which he tears down her walls and reveals her true self.

His thrusts were growing more and more powerful as he quickened his pace, fucking his woman like the dog she was. Kazuki was becoming frustrated with how half of his dick was being neglected, and he was determined to change that quickly. He wanted to bury all 16 inches inside of her, to ruin her for everyone else.

Dia felt lightheaded as she had orgasmed more times than she could count in this state, and she knew that this was only the beginning, that she was going to drench the bed in her fluids and stain the mattress once again. She was a babbling mess as she began to surrender herself to the moment, letting this stud use her as means of pleasuring himself.

Becoming increasingly more irritated, Kazuki leaned forward and placed a hand on the back of Dia’s head, pushing her deeper into the mattress as he mercilessly hammered away at her pussy. He was driving his dick deeper and deeper, pushing her womb upwards into her stomach before finally bottoming out.

“Y-You’re crushing my womb! Y-Your cock’s so deep!” Dia’s voice was raspy as she screamed without any prompt or warning, her feminine instincts compelling her to announce what was happening inside of her. She hated how degrading it felt, to be objectified like this, but she loved how good it felt.

Laughing at how the prudish girl was behaving no differently from a slut, Kazuki felt validated as an alpha male for having made her like this. He was still warming up and getting into the flow of things, as this wasn’t even close to what he was truly capable of. To him, bed breaking sex was considered the bare minimum to classify a fuckfest.

“Beg for it. Beg for me to flood your womb with my spunk, otherwise we’re ending it here,” Kazuki knew what he was doing, as he had made numerous amounts of women throw away their pride, to degrade themselves just for that momentary sweet release that fried their brains and revealed their true natures.

Moaning as the giant cock continued to bash against her womb, her insides clinging to it in a futile attempt to slow it down, Dia didn’t even think twice. She screamed at the top of her lungs, announcing to the heavens above, “F-Fuck me with that huge dick of yours! Wreck my slutty pussy and mark it as your property! M-Make me yours!”

“Cumming!” Kazuki drove his erection as deep as it would go, pinning his woman against the bed as he gave her no chance to escape. He could feel his balls tightening up, that all of the jizz that had been stirring about inside of his fat nuts was ready to be let loose. He was going to creampie her, to comply with her wish and make her his bitch.

Dia felt as if she was in heaven as blazing hot cum erupted into her womb, scorching the overly sensitive walls and coating them in a thick white layer of spunk. She was being marked, and while this isn’t the first time she’s been creampied, it was the most satisfying one by far. After all, she had admitted that she was no different than a slut.

Each spurt was as dense and copious as the last, and Dia could actually feel it sloshing around inside of her. There was just so much being shot into her baby chamber, and she knew that the hunk of a philander wasn’t going to stop anytime soon, that he was going to inflate her like a balloon.

It sounded absurd, and yet she knew better than anyone just how simple of a feat it was, that Kazuki’s ejaculation could be measured in litres.

Her belly had swollen from the absurd volume of cum inside of her, with not a single drop escaping as the monolithic cock plugged her pussy shut. As humiliating as it may have been to submit to this insufferable playboy, and how disgraceful it was to accept his seed, Dia didn’t seem to care.

An intense pleasure had been burned into her brain, her sense of reason now gone as a result. She was a broken mess of a woman, moaning euphorically as she basked in the afterglow of having been defiled by an alpha male. No one else could fill her up like this. No one else could satisfy her.

Not even breaking a sweat, Kazuki pulled his erection out of his slut’s pussy, watching as it clamped shut in a bid to keep the litres of semen from spilling out. It was a good warm up, and he was ready to keep going, to well and truly crush any remnants of rationality that may remain within her.

Hearing the sound of something vibrating, Kazuki hopped up from the bed and quickly narrowed down where it was coming from. Pulling a phone out of the pair of jeans on the floor, he was surprised to see that someone was trying to get in contact with Dia, that they were daring to disturb their fuckfest.

A devious idea popped into his head as he answered the call and handed the phone over to its rightful owner. Kazuki was met with confusion, and he kept his voice low and hushed as he told her, “It’s rude to ignore people. Don’t you dare even think about hanging up, otherwise I’ll never fuck you again.”

“H-Hello..?” Dia managed to stutter out as she rolled over onto her back, her bloated belly trying its best to weigh her down. She wasn’t in the state of mind to deal with anyone right now, and she was hoping that whoever it was on the other end of the call didn’t intend on holding a lengthy conversation with her.

She didn’t even think twice about what motives the playboy may have, nor did she even consider that he was toying with her. It’s not as if she trusted him, but she wasn’t as wary of him as she once was. Her body may have submitted to him, but what rationality remained refused to accept him as anything more than an insufferable prick with a huge dick.

“Onee-chan? Sorry to bother you, but I wanted to see what time you were coming home tomorrow. Everyone’s excited to see you,” the kind, uncertain voice coming from the phone belonged to none other than Ruby, her younger sister. She meant no harm, but she picked the worst time to call her.

Satisfied that his woman wasn’t disobeying him, Kazuki decided it was time to move into action. He climbed onto the bed and turned her onto her side, lifting one of her legs up and resting it against his shoulder before brutally slamming his dick back inside of her sopping wet pussy.

Unable to control herself, Dia let out an erotic moan straight into her phone’s microphone, giving her sister an earful of what a woman in heat sounded like. She clasped a hand over her mouth, but the noises kept pouring out as the inconsiderate stud mercilessly hammered away at her womb, causing the copious amounts of semen inside to slosh around.

“Um… Onee-chan? Are you okay? I didn’t call at a bad time, did I?” Ruby’s concern was loud and clear as she was evidently confused about what she was hearing. She hadn’t the faintest clue as to what was happening, so she could only assume that she had interrupted her while she was preoccupied.

What rationality remained inside of Dia began to flicker as her womb was pounded with enough force to make the king sized bed shake. Every time the philanderer's hips slapped against her, primal moans escaped through her lips.She was starting to forget what was happening, as she was immersed in the abrupt fuckfest.

“D-Dick..! K-Keep fucking me with that massive dick of yours! Please! Make my pussy feel good!” Pleading as if her life was on the line, Dia was practically screaming as her sense of reason shattered. Outside of her appearance, she was barely the same strict, studious girl that walked into the penthouse just a short while ago.

Kazuki chuckled as he continued to thrust inside of her, bashing against her cervix ruthlessly. He couldn’t help but to smirk at how much of a pushover she was, that she had just revealed her true nature over the phone to someone. He could only hope that they were close to his woman.

“O-Onee-chan..? I didn’t quite hear you. I’ll um… I’ll call you back later,” Ruby sounded flustered, as it was unclear whether or not she understood what was happening, or if she was just embarrassed to bother her sister at a time like this. Whatever the case may be, she hung up without waiting for a response.

Dropping her phone as she immersed herself in the toe curling pleasure, Dia was squirting like a fountain as she was impaled by the behemoth of a cock. She loved every second of this, and she wasn’t even concerned that she had several litres of cum sloshing around inside of her belly, or that she looked several months pregnant.

“You’re such a fucking slut, babe. Can’t believe you’d beg for my dick while you’re on the phone,” Kazuki both praised and mocked her, a wide grin on his face as he was quite pleased with himself for breaking her so easily. He wasn’t even close to done, and he could hardly wait to see how depraved she would be once he was drained.

Screaming hysterically as she received her second creampie of the day, Dia felt fulfilment like none other as she drowned in pleasure strong enough to fry her brain. Litres of cum flooded her already full womb, and with that giant dick acting as a plug, her baby chamber had no choice but to stretch out in order to accommodate such a fat load.

“I love this cooooooock!!!” Dia spasmed as she admitted her feelings towards the playboy’s manhood, proclaiming that she was unable to live with it. Even with an insane quantity of jizz sloshing around inside of her, she was still able to make more room for more, causing her belly to swell to unprecedented proportions.

Kazuki’s seemingly endless ejaculation brought up his bitch’s body weight, causing her womb to be just as heavy as the rest of her. He had to resist the urge to slap her yoga ball-sized stomach, as he had the creeping suspicion that it would be enough to break open the floodgates, and cause the contents to spill out of her pussy.

Even as he pulled out of her, Kauzki’s hulking erection was still throbbing, proof that he was eager for more. Watching as his mate slumped backwards onto the bed, he could only laugh at how pitiful she looked right now. Still, he found her to be quite sexy all things considered, and his instincts were demanding he claim what was rightfully his.

“It’s your birthday tomorrow, right? Y’know, I have a gift that a slut like you would just love, babe. You’ll feel like a whole new person, I tell you,” as selfish and inconsiderate as he may be, Kazuki wasn’t ignorant. He knew of the black-haired beauty’s upcoming birthday, and he wanted to give her a present, one that he hoped she’d accept.

In a trance as all that she could think about was that giant 16 inch cock and how good it felt to have sex, Dia just nodded her head in agreement, not knowing what she had just signed herself up for. If she were in a rational state, she would never even humour the thought of accepting a gift from this philanderer.

But now? Now she wanted nothing more than to please him, to surrender herself to her desires and worship the alpha male like that stud he is. Nothing else mattered to her at this time.


Hearing the sound of the doorbell ringing, Ruby hurried to answer the door. She had prepared a big party for her sister, and had even invited all of their friends for the occasion. It was all a secret, and she could hardly wait to see the look on her face when she realised that everyone was here to celebrate her birthday.

“Welcome home, Onee-chan!” Ruby shouted as she opened the door, her bubbly and energetic demeanour disappearing the moment she laid eyes on the person waiting on the other side. She could hardly recognise them, as they looked sleazy and unsophisticated, but she could see through her appearance and knew who it was.

Standing there was Dia, with bleach blonde hair and a fake tan. She wore a collared shirt with almost all of the buttons undone, revealing her ample bosom that was threatening to spill out of a tiny leopard print bikini. Her top was tucked into a plaid miniskirt that was so short that her matching leopard print panties were clearly visible.

Looking like a total gyaru, Dia didn’t seem the least bit concerned about her sister’s astonishment. To her, this was who she truly was, and if no one was willing to accept that, then she would just simply remove them from her life. It was that simple. She only needed validation from that insufferable playboy with a massive dick.

And no one was going to change that. She belonged to Kazuki, and she wasn’t ashamed to admit it.
