The newest member of the Occult Research Club, a black foreign transfer student that was living life lavishly day in and day out. Even now, he was busy taking care of his fellow peers, Xenovia, Asia, Koneko, Akeno, and Rias were all occupying his comfortable bed that barely had the space required to fit all four of them together at once. The room was heavy with the scent of musk, Issei was still none the wiser after it's already been weeks and all of the ladies were constantly all over the admirable stud that was still able to perform and produce despite the competition for his attention. 


“Sheesh, you’re really tight today, Koneko.  You must really be in the mood.” he commented, finding it particularly more difficult to thrust into her wetness today in comparison to the other various sessions that they had. Koneko was always the tightest of the girls, being that her body was also the most compact and smallest, slender but always providing a wonderful velvety tunnel for him to fuck with his enlarged black cock. 


“You’re right! Look at how she’s moving. She’s really going for it.” gasped Rias, covering her gasp with her hands.”


“Ara ara~... Our cute little Koneko must be starving today.” teased Akeno.


“I’ve never seen her like this usually.” chimed in Xenovia, rubbing her chin as they were all impatiently waiting for their turn. 


Asia on the other hand still somehow managed to act bashful in the large group, there wasn’t a single person that was wearing clothes as they were taking turns riding the humongous appendage that made its way throughout the entirety of the Research Club, ensuring that all of the ladies had their sexual needs taken care of was a diffcult job for him to manage, but it was a task that most men would kill to have. 


Koneko wasn’t a prude by any means, in fact she’d gotten rowdy just like the rest of them did when her womanhood was being speared by an incorrigible length at tremendous speeds, but there was an extra fire to her motions today. Even her body temperature seemed to have risen, as if she was in some sort of fever, her cheeks were rosy red, and her body was producing more sweat than normal, instead of being utterly dominated Koneko was holding her own and rolling her own pelvis against him, thrusting her hips towards his groin, intentionally skewering herself with his enormous lady killer stuffing her vaginal cavity to the brim while she desperately tried to fuck herself to completion using his tool as a meaty dildo. His mammoth hand held the frame of her tiny back while Koneko’s claws lightly scraped at his rugged, chocolate skin. In the midst of a freaky bout where she was even digging her teeth into him, not only biting him but her spurred moans were mixed with what sounded like seductive purring. Humping him with all of the might that her inadequate muscles could muster as the girls applauded at the scintillating display in front of them. 


A faint meow came from a different cat that wasn’t Koneko, there was a small black cat that was standing outside of the window, peering into the room with nobody’s attention on the little creature because of their undivided focus being on the attractive dark skinned man that showed them the time of their lives every day of the week. The cat’s tail wiggled, staring at the small girl with a piercing gaze.

A few days later…


The entirety of the Occult Research Club were planning on attending the school trip to Kyoto, having packed their bags, and in the middle of doing some last minute shopping before heading out on their journey. It was only then that a certain scheming individual set their plan out in motion, a curvaceous, mature-looking beauty with long, silky black hair. Her figure was voluptuous, and her eyes were a captivating hazel gold, with cat-like pupils that showcased her real identity. Her name was Kuroka, and she was the elder sister of Koneko, she was also the cat that was spying on her little sister’s activities a couple days prior. 


“That’s him, hmm? It feels different seeing him through the eyes in this form compared to when I was a cat.” thought Kuroka, subtly licking her lips with a sensuous gaze in her eyes, fascinated by the new foreign transfer student and the way that all of those girls naturally gravitated towards him. Rias, Akeno, Xenovia, Koneko and Asia were practically glued to his arms, it was like none of them wanted to be separated from the circle that it made it difficult for him to even walk around the mall. Kuroka snuck her way onto the train that they took to Kyoto, and waited for her opportunity like a predator would for its prey, calculated and calm. 


-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------


Later, when they arrived at Kyoto…


The group finally dispersed when the dark skinned stud decided that he wanted to take a break after the exhausting train ride over, after the countless rounds of sex that he’d endured, it would’ve taken a miracle for him not to feel phased in the slightest. Five girls at once was impossible for most men if not nearly all to manage, not to mention that he would’ve had to ejaculate inside each and every one of them at once in order to keep them satisfied. The way they treated his semen one would think that it was the most delectable drink on the planet, and without fail, he would always meet their expectations. That is precisely why he’d requested to hang back for the time being, and although his harem of beautiful, busty and salacious women were disappointed to hear it, they’d actually given him some private to himself and decided to go out shopping in Kyoto in the meanwhile. It’s not like he was dying to go shopping regardless, perfectly content with hanging back, and at the rather luxurious hotel springs resort that they were staying at, the man decided to check out one of the main reasons it was such a well renowned tourist location. 


“This is nice! I’m surprised that there’s nobody here, though. I guess it’s more popular to come later in the night, than this early in the day.” he chuckled to himself, leaning back comfortably against the rocks as he enjoyed the pristine water that soaked into his skin. Having come from overseas, he was still unsure of the proper dress etiquette, deciding that he might as well go commando since there was nobody else in the vicinity. While he definitely had a blast with the constant female attention surrounding him, with guys constantly exuding envy and jealousy just watching how they walked around together while clinging all over him like it was the most natural thing to do, sometimes a bit of peace of mind was like a breath of fresh air. Both unfortunately and fortunately for him, he had a visitor that he was completely unaware of. 


Somewhere behind the steam, Kuroko shifted out of her small cat form into her human one, following the man’s dress code and wearing nothing to cover her womanly features. Kuroka was a stunning beauty whose looks were only matched by the best of them, walking into the water and into the hunk’s field of vision with a teasing sway to her hips. 


“A-A sexy naked woman?!” he exasperated out of pure shock, wondering if he’d missed the point whether this was a mixed hot spring or not. Kuroka had actually done some prior tampering and flipped the signs to say that they were CLOSED for renovation after he’d entered. The thick, buxom beauty flaunted her enormous pale milkers that bounced with every step, everything about her seem refined, her crystal clear skin was pale and divine, and she had a sly smirk on her face while the man put little to no effort in hiding his ogling gaze, quite apparently enjoying what he was seeing.


“Well, hello there. I’ve been dying to meet you.” said Kuroka, purposefully standing in the water to allow his eyes to gawk at her heavenly hourglass figure for as long as he desired. They were both in the same boat, having never seen a foreign man herself, Kuroka was astounded by the spectacle before her. His defined muscles were chiseled and rippling in their darkness, the sheen of water coating his skin made him all the more desirable. If it wasn’t enough, the shallow end of the water allowed her a decent view of the genitals that she saw rearranging her younger sister’s guts just a few days ago. Kuroka eavesdropped on their conversations, and caught wind of the difference in sexual performance and genetics that black men were capable of. She liked what she heard, and definitely what she saw.


“You have? Have we met before?” he responded, out of all of the women that he’d ever met, Kuroka was the one that made him most anxious. Normally confident and believing that he was capable of bedding any woman that he’d set his mind to, for some reason Kuroka felt much older and more mature than he was.


“No, this is our first time meeting. I’ve heard a lot about you. My name is Kuroka, I am the older sister of a little lady that you know well yourself, Koneko.” introduced the seductive catwoman. Rubbing his eyes to see clearly, he noticed that she did possess distinct features that weren’t typical of a regular human. 


“Oh, Koneko’s sister?! This is a surprise, she’d never told me she had siblings. It’s nice to meet you.” he said, waving politely. 


“Damn! She’s hot as hell! I would’ve never expected them to be related, I mean… She’s stacked! Sorry, Koneko! But your sister’s a total babe!” he thought, gulping as Kuroka strutted her way closer, her eyes on the prize, aiming directly down towards his crotch. He noticed her gaze and sort of glanced at her with a curious look on his face. 


“Ah, that’s just like her. We have a bit of a complicated relationship, you see. Anyway, I'm well aware of your relationship with her, you two are much more intimate than your classmates would think.” she remarked teasingly, winking at him, noticing a slight blush forming on his face.


“Well… You know..”


“I’m not mad at you, I just wanted to see what type of man it took to charm a woman like her. I never expected the day that she would fall for a man. I always thought that other boy, Issei, was rather incompetent. You seem much more suited to the task. And I mean-… Oh. Wow. I take it that you must like what you see?” asked Kuroka, eyes widening and her inhaling a sharp breath at the sight of that dark object lingering under the water begin to grow, and fast. The ebony manhood had blood furiously pumping through its veins and eventually started to peek out the water, the fine sexy crown standing at the top floating above it, as even Kuroka felt rattled despite always being the teaser, and not the one being teased.


“Ah, my bad! I can’t control it, it’s hard for me to concentrate when a woman as beautiful as you is naked in front of me.” he confessed.


“I-I don’t mind. I like honest men. Y-You’re definitely on the larger side, hmm? And I’m not talking specifically about your body, but your-…” muttered Kuroka, pointing at his crotch that he didn’t even bother hiding. 


“Yeah, I get that a lot. I’m guessing that you like what you see, too?” he asked, standing up out of the water with his hardened prick bobbing and pointing directly at her. Kuroka’s mouth was hung agape, and she gasped audibly, seeing its length work inside of her sister’s body didn’t do justice to seeing it this close and personal. 


Large was an understatement, the man was impossibly hung. The dominant organ throbbed with virility, she’d never seen a finer penis in her whole life. No, it didn’t even feel right to describe the anatomy with such a tame word like “penis”. It was the cock that belonged to a real man, and Kuroka’s core felt hotter than ever, falling victim to the breeding season that had taken both herself and Koneko for a lustful trip. 


“Would you mind if I took a closer look at that? It’s not every day that I get to see a man like you.” she teased, flashing him a wink with a sultry smile on her face that caused his heart to skip a beat. Her charms were certainly working on him, he wasn’t the type of man that could be bound to a single woman. His superiority to other men meant that he should be shared gratuitously amongst the pretty ladies fawning for his attention. They were all smitten for valid reason, even Kuroka with her high standards and her playful attitude, found herself choked up at times from his intimidating phallus. 


“Go ahead, I can’t find a single problem with that. You’re not the first, and definitely won’t be the last. I guess you girls love seeing a huge cock, huh?” he boasted, lifting himself out of the water and taking a seat on the edge of the rocks. Kuroka swooped in to close the distance, and as if to inspect his male genitalia, her eyes were peeled on the incredibly endowed object. She’d never seen one so big in her life, it stood tall and proudly, bobbing with life and oh so dark and rigid. Kuroka licked her lips like a cat preparing to dig into its meal, the rush of pheromones that had Koneko on edge still lingered with Kuroka, a wetness forming in her pussy lips as she made a plopping noise in the water when she dropped to her knees, inching closer until her face was only separated by a few centimeters from his erection. 


They had only just met, and yet they were already becoming intimate. Such was the power of a man’s virility, the same pair of immense cock and balls that easily seduced any woman that was lucky enough to encounter her. Kuroka’s feline mannerisms amplified the arousal he was feeling, leaning back and groaning from the aggressive sniffing he felt from her nostrils, as if she needed to smell his musk to become better acquainted with his enlarged prick. A black cock was a first for the insatiable woman, whose lascivious moans sounded like croons, purring as her slender fingers wrapped around the heavy base and lifted it up, her smooth tongue flicking out of her premium soft lips and lapping at the tip, causing the muscular man to flinch in his dark buff was. 


“O-Oh, yeah! That’s what I’m talking about. I love getting blowjobs.” he admitted, admiring Kuroka’s work as she displayed exquisite skill and an innate ability to perform fellatio. Her glossy lips felt heavenly on his rugged, burly shaft. Despite his overwhelming size Kuroka only struggled for a few seconds before managing to slip several inches into her watering mouth, pushing forward and then consequently slipping into her clenching gullet. Kuroka didn’t possess a gag reflex which allowed for a sloppy throatfucking, unreserved in his movements as his hips seemed to have a mind of their own, closing his eyes and grunting heavily while the rapid developments took him by storm. He could hardly process the fact that Koneko’s busty older sister had just barged in on him in the springs and was now having her throat spasm around his huge dick with her fingers gripping his hard thigh. Kuroka’s head jerking movements were precise, quick and deep. Her saliva bathed his heated erection that was soon covered in a thick coat of spit, Kuroka’s ears perked as she noticed a faintly different taste from his chocolate cock, and it made her hips buckle just imagining what it would feel like to have her tight pussy stretched out by that fat, dense thing. It seemed to keep growing without warning, Kuroka rocked back on her haunches when it felt like the black stake was advancing far too deep within her esophagus. Groaning as her cheeks hollowed out and her plush lips trailed up along his inches with frantic bobbing motions of the head. 


“Mmm, yeah… Just like that.”


The plan that she devised in her head had this peculiar man bowing to her in submission, and yet Kuroka had already failed from the beginning, collapsing onto her knees and sluttily fellating his big black charcoal cock with hollowed cheeks. Her tongue rolling circles around the behemoth tool that plunged into her soaking mouth, her cheeks donned with a bright red blush that was produced by lust and her increased body temperature. Kuroka’s large butt swayed from left to right, eyes peeled open and staring intently at the man that she was servicing with her oral cavity. It didn’t feel right to not be dominated by such an incredible, masculine member. Kuroka felt like she needed to lay herself bare after just inhaling the scent radiating off of it, tasting delicious on her tongue with the pink wet muscle working the veins on the shaft and pushing him closer to an ejaculation. Kuroka’s cheeks tented when she tilted her head to the side and allowed for his jabbing dick to press against the flesh of her inner cheek, using her available hands to cup and massage the squishy balls that were dangling in their dark sack. 


“If you keep this up, you’ll end up with a mouthful of something really thick soon!” he warned, his broad chest heaving as he couldn’t help but push the bulge forming around her neck further along as he tested the depths of Kuroka’s throating capacity, the warm slimy walls wrapping around him wonderfully. Kuroka didn’t seem deterred by his warning whatsoever, instead it seemed to motivate her as she viewed the healthy milk that he would produce with that gigantic sack of his to be a reward rather than something to watch out for. Kuroka seized his rocketing length in and out of her sealed lips with reckless abandon, his black hog turning into a wet piston that left spit flying from her lips. Enveloping him fully all the way down to the cheeky base, his limits were quickly approached after having gone the longest time in a while without cumming inside one of his various lovers. Kuroka managed to crack a smile with her mouth slobbering everywhere, and to respond to such a cute face, the tall black man grunted with an abundant amount of sperm gushing out of his winking piss-slit and splashing into Kuroka’s dutifully working mouth. A development that neither of them planned for, the black rod throbbing intensely as the super rich and sweet tasting semen graced Kuroka’s taste buds with an elated look on her face. It tasted far better than she could’ve ever imagined, cum wasn’t supposed to taste this delicious, slurping maniacally as Kuroka’s hungry lips clamped down tighter around the pumping cockshaft, squeezing more of her appetizing treat from his exotic, ebony organ. 


“Damn! I let out a lot.” he sighed with relief, wiping the sweat off of his forehead as the steam from the hot springs was starting to get to him. The extra bodily sweat intensified his body odor that Kuroka found electric, increasing the saltiness of his burly girth that was completely washed over with the sheer amount of cream that he’d released inside of Kuroka’s mouth. It took her a few extra gulps and bobs of the head for good measure before disconnecting her wet lips with a loud pop. 


“Did you drink everything?” he asked.


Kuroka rubbed her swan-like neck and purred as she finished consuming her meal, a crimson red blush on her face as she was overtaken by the miasma of passion, as she finished devouring the chunky, copious load in front of him. It was commendable to a degree, but nothing out of the ordinary for the man who produced such tasty seed that there wasn’t a single woman that was under his wing that wouldn’t have done the same. Kuroka felt this inexplicable desire to impress him, her heart was pounding furiously in her chest as if something profound had taken over her. That black spear in front of her left her with an emptiness in her stomach, one that needed to be fulfilled by any means necessary. Losing her breath, she didn’t need to utter any further word on what their following course of action would be, rising to her feet, and even though she was far from the shortest woman, she needed to stand tall in order to reach for his shoulders. Instead of having her way by riding on top of him like she might’ve hoped for, the tables were flipped around in an instant, the man was just as eager if not more to engage in a duel of their sexes. Kuroka was the one that pounced on him, and yet she didn’t feel in control. The way that he effortlessly carried her without a hitch in his step was admirable, and proof of his indomitable physical prowess, it was true that she wanted to see the type of person he was because Koneko had never found herself a mate before, but in truth it was because Kuroka was jealous that she hadn’t discovered this man by herself. 


“O-OH!” cried out Kuroka, the meaty prick of his flared helmet already entering her plunging folds with the force of gravity pulling her down onto his towering, impending monstrosity. It was ridiculous how her entire body had flinched from the penetration alone, there hadn’t been a single penis yet that Kuroka seemed fascinated by, until now. Her nipples were already sharp like diamonds, feeling like she’d truly met her match. In truth, such a belief was a misunderstanding, she wasn’t on an equal playing level with the man at all, and soon enough that fact would become apparent to her. Kuroka’s toes curled up tightly when he grasped a possessive clutch around her hips, using them as leverage to lift her up and down his gargantuan tube of onyx like a playtoy, his muscles allowing her to feel relatively weightless which expanded the flexibility that he was capable of fucking her in this suspended position with. Kuroka’s back straightened out with rippling waves of pleasure exploding out across her body, reaching a heightened state of arousal as Kuroka couldn’t control herself, not her voice, and certainly not her convulsing body, lightly spasming after only the first few thrusts that packed emphatic force that couldn’t be compared to the other tame sexual intercourse that she’d experienced in her life up until this point.


Her mind was wiped completely blank, and her expectations were far surpassed, completely blown out of the water. Kuroka severely underestimated Koneko’s ability to take a cock, because she certainly wasn’t faring well whatsoever as the brutal thrusts clapped extra loudly against her skin because of the wetness from the bath. She was being stretched in a way that was hardly comprehensible, and she lacked control of performing any other action but to lay in his arms and moan as possibly loud as she could. His sturdy, rock-hard boner pushed the insides of her vaginal cavern into unknown depths, and Kuroka responded by rolling her hips in kind against his, her flailing legs barely having the presence in mind to straighten out before locking around his waist, trying to find some type of support to grip onto while her entire world was rocked in the matter of seconds. He seemed to be grunting or saying something but she couldn’t make out his words under the current euphoria that invaded her brain. 


“I don’t know what you expected by coming onto me dressed like that, but I’m definitely not the type to miss a chance like this!” he snickered, leaning back to watch as her entire plumpness bounced in combination with his grunts, his already rapid tempo somehow improving as he demonstrated an unmatched ability to fuck women into lifechanging orgasms. Kuroka had never been the first to cum once in her entire history of bedding men, and there was little she could do but have her churning insides contract tightly around his black behemoth and let loose a fountain of her own juices that spilled down his thighs. A shameful act, but one that Kuroka didn’t feel terrible or guilty about, she didn’t feel humiliated from suffering defeat to such a superior man. It felt like the sensation of satisfaction rippled throughout her entire being, all the way down to her limbs, and even fingertips. His thrusts were rough and deep, and they caused her violent orgasms to involve her whole figure, the incredible pace that they were already slamming together with somehow got stronger, more fierce. Kuroka’s eyes snapped open as she tasted the same heaven that Koneko did on that very night, and she fully understood why she’d become so attached. 


It felt like her vaginal walls were fluttering around the magnificent cock that was splitting her open, forcing her body to give in, she couldn’t tell if it was his hips or her own that were thrusting like a wild beast, nonetheless every single inch of his buried length was drilling in and out of her sopping wet hole. 


“Yes! Mmnnghh! Yeeess! O-Ohhnngghhh! Yeeesss!” celebrated Kuroka, it was as if instinctually she knew that she had finally found a true mate after all of this time, teasing, fooling around and searching for the one. All of the men that she’d previously met were nothing more than playmates, a way for her to pass time before inevitably moving onto the next man. They were hardly memorable, she couldn’t even remember over half of their names, or faces. Everything was so boring, there was no fun or thrill, they used their bodies to get themselves off, finished and then left. Those that fell in love with her were even more troublesome, Kuroka couldn’t find herself attached to men so unworthy. The desperate suctioning of her pussy lips was a sign of her acceptance, her orgasms were noisy, and she bucked and throbbed under the unbelievable pleasure. 


“This is exactly what I’ve been longing for…”


Her pink pussy had already become swollen with the lips inflamed, her clitoris was hard and erect, feeling his massive black cock swell inside of her with the veins grinding against her velvety walls. Kuroka’s entire pale body had become receptive, and he was grunting while mustering every ounce of his muscle to fuck her into submission. The way that it felt like he was barely trying at all, and yet still so skilfully turned her into a panting bitch in heat was remarkable. There was like a magnetic force connecting their colliding crotches as Kuroka used her remaining bits of her strength to hump herself to completion, reaching a visceral orgasm that was matched with the handsome foreign stud that pushed every sloppy inch of his pillaging battering ram inside of her quivering insides. 


“Uuggghhh! I’m cumming, Kuroka!” he announced vehemently, feeling her buttocks clench in his grip as her wailing moans echoed resoundingly as their heads were tilted back together in unison, in equal wonder. Their mixed residue splashed out of their connected bodies, and splashed onto the ground, Kuroka was scouting for her next potential playmate, but instead becoming his feisty black cat, and his alone. Kuroka had a victorious, yet orgasmic look on her face, the whole purpose of the mating season was for her instincts to lead her to the special someone, and finally she’d met the man that would surely produce all of the kittens that she wanted with. A virile man, an admirable person, and someone that she would never want to have sex without. 


Her stomach swimming in gooey warmth, they stared at each other intimately. 


“You think we got time for another round?” he asked.


“I don’t know. But I don’t think I’ll care if anyone walks in right now.” answered Kuroka, with a husky tone to her voice and biting her bottom lip seductively. 


-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------


A few hours later…


“Where could he have gone? He hasn’t come to our room, and he was supposed to be sleeping here.” mused Rias, tapping her chin and trying to rack her brain at where he could possibly be. Akeno, Asia, Xenovia and Koneko were all patiently waiting for his return, until the door slid open to their room, the man of the hour walking in with the girls facing lit up with excitement 


“Hey.” he greeted them all, with a black-haired bombshell glued to his bicep. 


“Hmm? Who’s that?” 


“S-Sister?” exclaimed Koneko, purely out of shock. Judging from their disheveled hair and the familiar scent lingering from their bodies, the nature of their activities were evident. 


The infamous stray criminal had all but been claimed, and they definitely wanted to hear them out for an explanation.
