Chapter 1 - The Tachibana Sisters Infidelity

Notes - All characters in this story are the age of 18 or above. If you‘re a fan of Natsuo, (not sure why you would be one, especially if you’re caught up with the manga, but to each their own.), then I would highly recommend not reading this story. Heavy NTR themes and a pretty messed up premise.


Contains - Netorare, Impregnation.


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


One of the biggest tragedies to have ever happened to Natsuo and his family occurred. Hina was being trailed by her stalker, Kengo Tanabe, a man of empowering wealth and possessed greatly respectable stature. All of this lit up in a blaze when he was exposed for the crimes he was committing, leaving him jobless, with nothing left as he was put on house-arrest as the investigation on his case continued. In a last-minute effort to exact his revenge after being ridiculed, he attempted to bring Hina along with him, tracking her down and lunging at her with a knife in a crazed effort at murdering her in the dead-center of the street. Under the impression that he was still trapped at his home, Hina was nearly stabbed on her way to work, only to be saved at the very last minute by Natsuo, who managed to push her out of harm’s way and accept the blade in a heroic effort. Of course, life is far from a fairy tale. Luckily, Kengo was later imprisoned and charged with attempted murder, domestic abuse, and stalking amongst the many crimes he’d committed in the past. But, this all came with a price, which was potentially Natsuo’s life as he was put in a comatose state for an undisclosed amount of time.


This was all happening without his knowledge, but both Hina and Rui were visiting him on his hospital bed frequently. A long time had passed, as this routine continued, leaving everyone wondering if, and when, Natsuo would finally awaken from his deep slumber. During their time visiting, they happened to meet a rather charming man who was at the hospital getting his broken foot checked. In their times of grief and discomfort, he served as a pillar of support as he cheered the ladies up through their various conversations. Eventually, the relationship between the man, and both Hina and Rui had gotten closer and closer, until the point where they stayed in touch even when his foot had fully recovered.


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


Nearly a year later..


Natsuo Fujiii woke up for the first time in months, having no recollection of how much time had passed as he drowsily sat up on the bed. His whole body seemed to lack strength and he felt extremely weak as the memories of slowly creeped back into his mind, remembering why he was there in the first place. The nurses and doctors rushed in a hurry when they had realized he was awake, providing him with the proper treatment to undergo a speedy recovery. It took a few days before he was given permission to get released. While there were a lot of worries on his mind, he was instructed that his utmost priority was to follow the proper procedures and focus on his health. With that in mind, he decided not to contact his girlfriend, Rui, and the woman that he cared enough about to risk his life for, Hina. While he wanted to plan a big surprise for them, a part of him felt pretty depressed that he had no visitors. “I know it’s been a long time.. But would it kill for anyone to visit me?..” he thought, a bit irritated but not selfish enough to understand that they probably had a lot to deal with on their hands. Finally, the day where Natsuo was discharged from the hospital was reached, able to walk on his own two legs after months of being strapped down to a bed. He called a taxi-driver to bring him home, still intending to surprise his family back at home. 


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


Nearly half an hour later, arriving home..


Natsuo took a deep breath, feeling a lot more nervous than he’d imagined as he knocked on the door. A few seconds passed with no response, leaving him to wonder if nobody was home at the moment. He tried a second time, this time knocking much louder in hopes that it would be noisy enough for someone to pick up on. “Still nothing?..” he thought, waiting patiently as he swayed back and forth. It wasn’t until nearly a minute later when the door slowly opened. “Hello?...” muttered a familiar voice, belonging to that of his ex-girlfriend, Hina. “H-Hey!..” he nervously responded, unsure of how she would respond to his surprise. “N-Natsuo!~...” she said with a huge smile, embracing him momentarily before pulling back after a few seconds. Now that he was much closer, he noticed that there was a red tint to her cheeks, and she was breathing a bit heavily too. “I’m back!.. Where’s Rui?..” he asked quizzically, welcoming himself in the house as he took off his shoes. “R-Rui?!.. Ah!... Well.. I think she went out to buy groceries…” nervously said Hina, her smile dropping for a moment and leaving Natsuo confused as to why she was struggling to say something so simple. “By the way.. There’s someone I’d like you to meet, Natsuo..” she said, grabbing onto his arm and dragging him to the living room. “Is there?...” he asked, wondering who she was talking about. 


Hina brought him to the living room, and to his surprise, there was another man standing behind the kitchen counter. “He’s been helping us out at home since our parents went out on a trip together.. We’ve been visiting you at the hospital a lot but this week has been really busy! Sorry about that!~..” apologized Hina, clinging onto his arm as she was genuinely happy that he was alright. “Oh?.. Is that so.. Well.. Thanks for looking over the girls..” said Natsuo, politely bowing down to show his gratitude. “Ah.. No problem.. They’ve been the ones taking care of me.” he responded, leaving Hina silent and averting her eyes at the possibly double-sided comment. There was an uneasy feeling in Natsuo’s chest for some odd reason, unable to quite put his finger on the reason why, but it was most likely the fact that no matter how you looked at it, their situation was at least normal to raise some level of suspicions about. “Maybe I’ll grab a drink..” thought Natsuo as he started walking towards the kitchen, until his arm was suddenly yanked by Hina. “D-Don’t worry about that!.. You need to rest.. Wait at the table and I’ll treat you.. Oh, I still have some leftovers from earlier on the dinner table!..” she said in a hurry, dragging him over and allowing him to take a seat. “Alright, alright..” said Natsuo, sighing as he sat down on the chair, watching as Hina frantically brought him a cup from the nearby cupboard. “What’s that guy even doing?.. He’s just standing there..” wondered Natsuo, who noticed that the man was just standing still, not even a phone in hand or anything. “Let’s eat together, Natsuo!~..” cheered Hina as she took the seat right next to him, striking up a conversation as he was distracted from the stranger that was “taking” care of his stepsisters, as he put it. Something about him just didn’t bode well with Natsuo. Not only was he on the good looking side, but being willing to watch over someone’s house was a bit confusing, especially since he had no knowledge of what exactly Hina and his relationship was. “Well.. I can think about that later..” he thought while he decided to enjoy his meal, and talk with Hina who seemed to be beaming with topics. 


Little did Natsuo know, the fear hidden deep down inside was warranted, yet he was still completely oblivious to his surroundings. “Rui… That feels good…” whispered the man as he placed one of his hands on her head, foolishly finding himself closing his eyes in delight as the bluenette kept her lips wrapped around his shaft. Both of their hearts were racing at the incredibly risque situation, her boyfriend was sitting just across the room and here she was, sitting on her knees with another man’s cock lodged inside of her mouth. The part of her that maintained her sanity felt absolutely terrible about what was happening right now, but was suppressed thanks to the uncontrollable lust that was taking control of her actions. “Sorry, Natsuo.. I’ll come see you in a second..” she mentally apologized, closing her eyes and slowly moving her head back and forth, carefully motioning the bobbing of her head in order to not make any noise, not wanting to accidentally slurp on the tasty manmeat that she was passionately sucking just minutes earlier. “Mmph…” she lightly moaned when the bulbous head reached relatively deep, the man accidentally buckling his hips with his mind off in “La La Land”. “Shit, sorry..” he whispered into his palms, not wanting to appear suspicious when he noticed that Natsuo shot a glance towards his direction. Not wanting to risk making any more potential noises, Rui opted to carefully play with his cock with the use of her tongue, caressing the sensitive slit with her slimy muscle, sliding it underneath the hefty shaft and pushing it up against the roof of her mouth. It took all of the man’s might not to groan like a pleasured woman as his fingers tangled within her blue locks, always impressed by how talented Rui’s fellatio had become. Typically she wasn’t the type of woman who was daring enough to pull an absurd stunt like this, but they were caught off guard and Hina was so shocked by Natsuo’s arrival that she carelessly allowed him in. There was also the option of getting off her feet and greeting her boyfriend, but how could she explain why she happened to be crouching underneath the counter whilst standing directly next to another man?


Well, it was partially her fault for continuing despite hearing the door open, and the conversation happening in the hallway. Rui cursed herself for not reacting quickly enough, too enamoured by the masculine taste of his penis to pull away with haste, even if the situation needed it. “Ah.. Why am I so horny right now?.. Have I always been this perverted of a woman?..” she thought while slowly nudging forward, pressing him against the back of her throat and managing not to stifle a gag, something she’d picked up on after the many times she had his dick in her mouth. “Hey.. Are you alright back there?..” asked Natsuo, noticing that the man had a bit of a blush on his cheeks, almost like he was breathing too fast due to a fever or something of the sort. “M-Me?.. Yeah.. I’m completely fine!..” he stammered, feeling Rui’s lips crawl up the centimeters of his shaft that wasn’t properly inserted inside of her wet orifice. She held her head still and peeked her eyes open, staring intimately at the face of the man she was pleasuring as he failed to stifle a stray groan. Luckily Hina was doing such a wonderful job at catching Natsuo’s attention that he didn’t notice.


 “I’m gonna-...” he cut himself off, nearly announcing to the entire room that he was about to blow his load. Natsuo couldn’t understand what his deal was, after all he was under the impression that Rui was out buying groceries, so his first impression of the man was that he was some sort of weirdo. The sexually conflicted woman held her breath and closed her eyes when she felt the ensuing throbbing commence, having no other choice but to take everything inside of her mouth as to not stain the floor and leave behind any evidence. The man covered his face with his hands as his elbows rested on the table, breathing heavily as he continued ejaculating inside of Rui’s mouth. She dutifully gulped everything down, forced to swallow rather slowly, making it increasingly difficult to keep her puckered lips locked tightly around the shaft. Her frantic breathing caused the warm air from her nostrils to tickle his pubic region, cheeks bulging as she repeatedly worked her throat for nearly a minute longer, until his erection finally simmered down. “Ah….” he sighed in relief, pulling out from the tight lock of her lips and placing his wet member back inside of his trousers, zipping himself up after pulling up his boxers. 


Rui was about to foolishly rise to her feet as she wiped her lips with the back of her hand, but luckily the man was attentive enough to stop her in her tracks, pressing her down by the head and keeping her on her knees. “That was a good meal.. I’m stuffed!.. Thanks, Hina..” said Natsuo, getting up and out of his chair. “Oh, no problem!..” she responded. “I’m getting pretty sleepy.. Maybe I’ll go take a nap…” he said while yawning, stretching his arms and back after being sore from laying down on a bed for months. “Wake me up when Rui gets here, okay?..” he asked, a tinge of pain inflicted on her heart was she was shamelessly committing adultery. “Okay!.. I’ll let you know.. Have a good sleep, Natsuo!..” cheered Hina, watching as he walked away and into his room. A few seconds passed by before there was a collective sigh in the room, the tension finally disappearing when they were all finally left alone. “Hina!.. Why didn’t you tell us that Natsuo was coming?..” whispered an angry Rui, who still had a smidge of semen trailing down the sides of her lips, her older sister wiping it away for her. “S-Sorry!.. I was just so excited that he was alright again!..” apologized Hina, who yelped when she felt a hand grab the fullness of her ass. “You almost got us in some trouble, you naughty girl..” he teased, pulling her against him. “S-Stop!.. Not now.. What if Natsuo finds out?!..” asked Hina, and yet did nothing to reject his advances. “Come on.. It’ll be alright.. He’s tired, isn’t he?.. We’ll give him a few minutes and then he’ll be passed out by then..” he whispered while clutching Rui’s butt with his other hand, walking the ladies over to their room.


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


A few minutes later…


With Hina and Rui sitting by his sides, the luckiest man in the world was taking turns making out with each of the sisters. Right now, the man was currently engaged in a passionate lip-locking with Hina, making up for the time lost together when she was doing the duty of distracting Natsuo. “Mmm…” the older sister moaned into the kiss, allowing their tongues to swipe and tangle together as they dueled for dominance. Hina was more pent up than usual, deepening the kiss as she eventually shoved her tongue inside of his mouth. On the other arm, Rui was massaging the bulge in his pants back to life, patiently waiting for her turn as she watched her sister and the man make out like lovers. “Mmnph!... I want it…” panted Hina in between kisses, her hand slipping underneath his shirt and feeling up his abdomen. “But.. Natsuo’s might still be awake..” muttered Hina, tightening the grip of her hand behind his neck, pulling him back for some more smooching before he could respond. “Oh?... Come on.. He should be completely asleep already.. Didn’t he mention that he was really tired? Don’t worry, we’ll be alright..” he tried convincing the ladies, except both of them were still rather on edge about going through with this. It wasn’t a secret that Rui and Hina were quite noisy in bed, all too familiar with their sexy moans that always succeeded in making him even hornier. 


“Hmm.. If you’re too scared to have sex right now.. Why don’t we start off with a little bit of foreplay?..” he suggested, unzipping his trousers and pulling them down his legs, his big cock lurching out at the two women. It never failed to amaze them, no matter how many times they laid their eyes upon his gifted member, Hina and Rui would always salivate at the sight. “Eh?.. Were you unsatisfied by all the work I put in at the kitchen?.. I almost got in a lot of trouble, you know!..” pouted Rui as she swiped her finger on her bottom lip, playfully nudging his shoulder after. “Of course not!.. I’m sure all the proof you need to know that I enjoyed it is found somewhere around here..” he teased, rubbing her stomach to remind her of the wonderful job she did when swallowing his load. “Anyway, enough of that.. Let’s get started before he wakes up, alright?..” he replied, his hand that was wrapped around Hina’s back being used to grope her bountiful breasts. “Fine!~ Don’t be too noisy, alright?..” replied Hina, leaning down and doing him a favour, wrapping her large mounds around the sturdy shaft. “Hey!.. That’s not fair!..” complained Rui, who had to strip out of her shirt before joining her sister, because Hina’s was already taken off during their intimate makeout session. 


“Ah…. This is heaven…” he groaned while throwing his head back in pleasure, both of his arms bent back and resting on his palms, delighting in the wonderful feeling of being smothered by both of their soft titties. Obviously Hina was far bustier than her younger sister, but that wasn’t enough to make the determined Rui shy away from a challenge, making up for what she lacked in terms of figure with sheer passion and technique. “Oh!~....  That’s it..” urged the man on as Rui’s nipples collided with Hina’s, squeezing him inside an addicting, wonderfully warm softness. What made it even more intriguing was Rui’s tongue happily licking the underside of his shaft, giving her the benefit of the doubt when comparing how skilled at performing fellatio between the two sisters. Hina eventually realized that she was behind the curve, slithering her tongue out to make sure that she wasn’t one-upped by her younger sibling. Occasionally the eager lapping of his cock caused their wet muscles to touch, the two sexually aroused women far too enamoured to care, unbothered by the sinful contact that occurred as they made love with the exposed area of his dick with their mouths. “Unbelievable~...” he praised, never feeling more exhilarated and grateful than ever. Their double boobjob proved to be much noisier than anticipated, slurping noises echoing throughout the room because of the frantic licking of their tongues and the occasional suckling of the head. Hina’s lips and Rui’s touched as they kissed, but with his rigid cock in the way, their tongues meeting at the side of his cock with his skin drenched in their saliva. 


The dynamic duo of these two naughty, unfaithful and downright sexy pair of sisters combined their eager tongues with the erotic motions of their breasts, squishing the elongated member in between their cleavage and stroking up and down with their tits. “Ah.. I’m getting close…” he whispered because he barely managed to stifle a loud groan, proving to be even more difficult when Hina’s lips enclosed around the head, bobbing up and down as she started hogging his dick all too herself. Rui glared at her sister after being relegated to only tending to the shaft, but happily doing it regardless. “I’m going to cum!...” he warned, erection throbbing as he moaned from Hina’s excited slurping. “Hina-nee!~...” complained Rui as she tried pushing her sister away, knowing that she was planning on hogging the sizable load all to herself, refusing to let go of the tight grip that her lips had on his cock. She finally conceded at the very last moment, backing away just in time to properly prepare for the eruption as she tilted her head back, sticking her tongue out with half-lidded eyes filled with lust. “Here it comes!~...” he grunted as semen spewed out from his tip, shooting straight up in the air before landing down onto their stuck-out tongues. It wasn’t quite the mouthful that Rui was lucky enough to receive earlier, but Hina was satisfied as she continuously grew more accustomed to the musky taste with every opportunity she had to taste him. Feeling a bit greedy, she sneakily inched forward and pressed her tongue against the slit, getting more of his spunk on her face and as a result even more inside of her mouth. Rui’s eyes were closed as she was unable to see, only able to accumulate a decent amount as his exotic taste lingered on her taste buds. “Ugh… That was a pretty good warmup, right?..” he panted, leaning back as he stared at his two sexfriends covered in his cum. There was a simultaneous gulp as both sisters happened to swallow at the same time, a relieved sigh after successfully consuming the load. “Mhmm~...” moaned Hina as she nodded, licking a circle around her lips to catch the stray globs of semen that surrounded her pretty face. Rui was nearly equally as soiled as a decent amount of her face was also covered white, leading the older sister to grab her chin and pull her closer, sticking out her tongue and licking a line right up her right cheek. “Hina-nee!~.. Stop that.. You’re so naughty!...” complained Rui as she backed away, blushing from the erotic act of her clearly perverted sister. “Sorry!~.. I couldn’t help it..” replied Hina, cleaning herself up with her hands and then licking it off her fingers. 


“Wow… That got me all fired up~..” said the man with a grin, impressed with the two sister’s bodies of work. Perhaps they were amped up because the man that they supposedly loved was sleeping nearby, their inner depraved, slutty nature finding enjoyment in these twisted circumstances. As messed up as it was, the passing of time didn’t serve well for their devoted loyalty and affection towards Natsuo, while their feelings for him were obviously closer on the romantic side, it appeared that anything revolving physical and sexual relationships, this man had all but swept away. “I really want to fuck you two right now.. But, I guess if you’re not up for it.. Then I’ll be heading home…” teased the man, pretending to stand up and leave before both of his arms were clutched in between their breasts. “No!...” they both replied in unison, pulling him back down to take a seat on the edge of the bed. “Really?.. Even if your boyfriend is sleeping under the same roof?..” he said. “H-He’s not my boyfriend!...” stammered Hina, who told him about their relationships as exes sometime when they first started talking. “......” Rui stayed silent as she had a deep blush on her face, unable to come to the terms that she was actively committing adultery, and yet still managed to be intensely aroused in the process. 
Their fear of him possibly being awake and overhearing seemed so insignificant in comparison to their rampant urges that came to fruition during their extremely lewd boobjob. “Then.. Can I take that as an agreement that you two will be my girlfriends?..” he whispered, watching as the two girls had already begun stripping off the remainder of their clothing, evidently aroused with their apparent wetness serving as proof. “Huh?... You’re still going on about that?..” muttered Hina as she was placed against her back, heavy boobs jiggling from the sudden movement, biting down on her finger in preparation to silence her moans. Rui wrapped her arm around his neck as she crawled towards him, pulling him into a kiss as she skillfully penetrated Hina without even needing to open his eyes. “Nngh!~...” she moaned, voice muffled as the man started thrusting inside of her tight entrance, reaching so incredibly to the point where she was wondering if she was getting addicted to the amazing sensation.  “Mmmnn…” they both moaned into the kiss, with the man’s hands gripping tightly around Hina’s waist as he pulled her voluptuous body directly against his crotch. The slick noises from her sopping wet entrance filled the room as her moans grew louder, perhaps audible from the nearby rooms. “Ahn… Ahn… Ahn!~...” she moaned as her body shuddered from an orgasm, amplified by the groping of her chest as he teasingly twisted her sensitive nipple. “Oh!~... You’re so fucking tight… I’m gonna blow.. Can I do it inside?...” he asked, breaking away from the kiss momentarily and knowing fully well that there was a slight chance that she wouldn’t want him to finish inside without a condom, but the depraved look on her face completely gave her answer away. “Unngh!~...” he groaned as he creampied the busty brunette, watching her squirm from the corner of his eyes as he peeked them open in the middle of his intimate kiss with Rui. 


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


Several hours later..


Natsuo was in a deep slumber as he comfortably slept on his bed, oblivious to the carnage happening around him as he was clueless about the developments happening right under his nose. If he were awake, it wouldn’t take a genius to figure out what was going down in the nearby room, thanks to the powerful moans coming from the two women he currently held feelings for. Instead, he was left with the short end of the stick, having a wet dream about them meanwhile another man was giving them exactly what he was fantasizing about. 


Rui and Hina were taking turns getting piped by his manly cock, a lewd expression dawned on their faces as they were completely lost under pleasure, unable to remotely think about the possible consequences of their actions. “Inside!... Keep cumming inside of me!~...” urged Rui as she was face down against the mattress, ass sticking out like the whore she was as he repeatedly slammed his hips against her. In the heat of the moment, Hina agreed and allowed him to cum inside under the pretense of “impregnating” her, given the fact that he’d run out of condoms and wasn’t nearly finished just yet. He groaned as his penis spasmed deep inside of Rui, pouring all of his semen inside of her womb as she bit down on the nearby pillow to stifle her moans. Her legs jerked upwards thanks to the overwhelming pleasure of her impending climax, heart thumping loudly as this was a line that she’d always vowed to never cross. Rui’s resistance was uncharacteristically weak as something seemed to be stirring her up, heavily debating whether or not she would need to take pills after this night came to an end. “Ha… Ha…. Ha….~” the two ladies panted as they were left incredibly exhausted, semen spilling from their stretched pussies from the constant ejaculations that were shot directly inside. The man cooed as he lazily pulled out of Rui’s snatch, laying on his back and wrapping his arms around both of their necks as he snuggled them closely, carelessly drifting to sleep along with them, this type of night slowly becoming routine as they all but forgotten about Natsuo sleeping in the other room. “Goodnight…” he whispered before closing his eyes, equally drained as his cock was milked completely dry. 


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


The next morning…


“Huh?.. What time is it?...” said Natsuo as he yawned, stretching his arms out as he looked around him, still getting used to his surroundings, as waking up in a hospital bed felt normal at this point. “I must’ve passed out.. I wonder if Rui’s home already?...” he thought while hopping out of bed, figuring nobody was currently awake as not a sound was heard throughout the house. “Hm?... That guy didn’t go home already?.. Don’t tell me…” thought a confused Natsuo as he noticed the man’s shoes still at the doorway. With caution, he approached the one room that was still closed, taking a deep breath as his heart was racing for a reason currently unbeknownst to him. Slowly, he turned the doorknob as the wooden door creaked open……
