(wtf am i doing)

Shinpachi groaned as he came to, head throbbing, ears ringing. His limbs ached, and he felt like he'd been hit by a spaceship. His mouth was dry, his throat scratchy.
He groaned again as he tried to sit up, only to flop back down on the bedding with a frow. His body felt weird, and it wasn't quite moving the way he told it to.
Shinpachi shook his head, trying to clear it of cobwebs. Where was he, anyway? He didn't recall going to sleep... in fact, the last thing he could remember was breaking a waster over someone's head. And then, nothing. Just blackness.
Odd.
Shinpachi shook his head, rubbing his temples with a wince. He narrowed his eyes in an attempt to investigate his surroundings, but without his glasses on it was a futile gesture.
Speaking of which...
"Where ARE my glasses...?" Shinpachi wondered aloud, groping blindly around his person in search of aforementioned spectacles. His search soon came to an end, however.
His eyes widened when he felt something suddenly pressed into the palm of his hands.
"Wha...?" he muttered, confused. He squinted and stared ahead, and he realized that he could make out a large-ish, vaguely person-shaped splotch kneeling down on the floor beside him.
"You were looking for these, right?" came the voice of the person next to him, and he recognized it as belonging to...
"Ane-ue?" Shinpachi said uncertainly, taking the glasses and lifting them up to his face. "What happened...?"
His eyes then widened when he realized that Otae seemed to have gained a foot or two in the time he'd been out of it.
"What the hell?" he said, staring at his big(ger than usual) sister. "Did I shrink or something, Ane-ue?"
Otae giggled.
"Or something~" she told him cheerfully, a bright smile on her face. Her eyes flitted toward his crotch, and Shinpachi followed them.
His eyes then widened, and his face grew red, mortified.
He had an erection. In front of his sister.
He was mortified by this revelation, so embarrassed he could die. Desperately, he tried to draw his sister's attention away from the bulge. But it was too late. She had already seen enough.
Otae smiled knowingly when she saw the sizable bulge in Shinpachi's covers, the scent of his arousal filling her nostrils even from there. She felt a wave of warmth wash over her as she cast her eyes over her younger brother's new, childish frame and considered the fact that they did not have any clothes which fit him as he was now.
She felt heat build in abdomen at that thought. Her little brother was completely naked under his covers – she should know, having been the one to put him to bed in the first place.
"Shin-chan..." she murmured, unheard by her brother as he cheeks grew dusted pink. Her pussy was aching as she recalled the appearance of Shinpachi's body when she had first stripped him of his clothes after he'd been brought home by Kagura and Gin-san.
He had seemed so frail, at first, so small and light in her arms. But then she had seen his member, and all such notions had been thrown out the window. It was not the first time she had seen Shinpachi naked - he was her little brother, after all – but she had not seen him full-frontal nude in a number of years. Still, she wasfairly certain that Shinpachi had NOT been nearly so... well-endowed... the last time he'd been that size.
She blushed again just from the memory, imagining what it would feel like to ride his massive...
She then yelped and fiercely shook her head, causing Shinpachi to blink and stare at her curiously.
"Ane-ue?" he said, concern in his voice. "Are you alright...? What's going on...?"
Otae smiled in spite of herself. Ah, he was such a sweet brother, she had to admit. He cared about her very much, she knew, and he was just as dear to her, even if she was a little bit tough on him at times...
But still, as close as they were, the things Otae found herself wanting to do her brother – and even more wanting him to do to her – were NOT things that should be done between siblings, regardless of how close they were or were not.

... Still, though... she could not help but wonder...
Tae smiled at Shinpachi, though her eyes were focused further south. Despite her best efforts, she was finding it difficult to resist the seductive whisper of temptation. It was human nature to desire what one could not have, and Shinpachi was her forbidden fruit.
"Shin-chan..." she found herself saying, "Would you be a dear and take off those covers? I need to make sure you aren't getting any bedsores..."
That was a blatant lie, as Shinpachi had not been bedridden nearly long enough for any such things to form, but he didn't know that, and he had no reason to mistrust her. Though he did seem a bit flustered at the idea of letting her examine him – probably in no small part because of the considerable erection he was currently sporting under those covers.
But Tae Shimura's word was as good as law in their household, and so, after a moment of pained hesitation, Shinpachi reluctantly pulled down his covers, exposing his body. He winced reflexively, expecting a negative reaction of some sort from his sister, but he didn't get one – not unless you considered Otae taking his member into her hands and playing with it to be negative.
Shinpachi gasped at the feeling of his sister's smooth, soft hands on his erection, and his eyes widened in shock when he looked down and saw that she was giving him a handjob.
In the midst of horror at his predicament and disbelief at what his sister was doing, a small, long-suppressed part of Shinpachi's subconscious rose to the fore. Shinpachi Shimura had long been teased by his fellow yorozuya of having a sister-complex, but it was dubious whether or not Gin-san and Kagura-chan ever realized just how accurate their comments actually were.
Shinpachi was attracted to his sister, a deeply rooted sexual attraction dating back to his earliest years of puberty, but this attraction was deeply suppressed for fear of crossing boundaries which could never be un-crossed. He knew, on some level, that his affection for his elder sister, for Tae Shimura, was not entirely wholesome in nature, but he fought back those desires at every corner, suppressing them to the point of nearly convincing himself that he simply cared about his sister like a brother should.
But all those years of careful suppression and restraint flew out the window the second Shinpachi saw his sister touching his member, playing with it.
He moaned, shivering pleasurably as Otae softly squeezed his dick in her hand. A faint blush was on the slender brunette's face, and she was smiling sultrily. The experienced cabaret girl kneaded her fingers into his stiff, throbbing meat, expertly working the shaft of her brother's impressive cock. While Otae had never personally administered "that" sort of service to her clients (and, indeed, disapproved of those who did, such as that shameless hussy of a shrine maiden), she had heard enough from her more... perverted... coworkers to have a good idea of how to please a man if it ever came up.
Like right now.
Tae smiled, glancing up at the look on Shinpachi's face, then licking her lips as she looked back down to his penis, the tip of which was glistening with precum. The musky, overpowering scent of her brother's sex filled her nostrils, so strong that she could practically already taste it.
"Sublime..." she moaned, eyes nearly rolling back in her head as she inhaled deeply. "Simply sublime, Shin-chan..."
Shinpachi groaned, shivering. His dick was throbbing mightily in his sister's hands, and it felt like it was ready to burst. The pleasure was incredible, on a whole other level from what it felt like to do it himself.
And he wanted more.
"Ane-ue..." Shinpachi groaned as he slowly, shakily got to his feet, "I... I want to... I want to..." he stammered nervously.
Otae smiled.
"Does Shin-chan want a pony-ride?" she asked sweetly, getting down on her hands and knees, slipping out of her kimono. Her words sounded harmless in tone, but her actions belied a rather more perverted meaning to them.
"Yes...!" Shinpachi all but exclaimed, finding his eyes glued to his big sister's naked body. "I do!"
He was so busy taking in her lovely form that he did not even register the fact that she seemed a fair bit taller than normal, or indeed that his surroundings appeared to have been scaled up in size relative to him. All he could focus on was his sister's nakedness: her small, petite breasts; her smooth, flat stomach; her firm, round ass; her shapely hips and blossoming flower – these were the things which commanded his attention.
Otae giggled, and she turned around, still on all fours, so that her booty was barest inches from her little brother's not-so-little manhood.
"Then hop on, Shin-chan~" she purred, wiggling her hips invitingly.
Unable to hold himself back with his sister's bare ass right there in front of him, Shinpachi hopped on. He lined his hips up with her bottom, wrapping his arms around her abdomen as he fervently rubbed his erect member between Otae's butt cheeks, grunting and groaning in pleasure from the sensations he was experiencing.
Tae, for her part, was smiling happily at the feeling of her cute little brother rubbing himself against her ass. She giggled playfully, enjoying the stimulation. She crawled around the room on all fours, bouncing her hips up and down as she gave Shinpachi a pony ride.
"Are you having fun, Shin-chan~?" she cheerfully asked her brother in a bubbly tone of voice. Otae was so enamored with his cute new/old form, and so aroused by his potent pheromones, that she found nothing wrong or improper about what she was doing.
"Y-yeah..." Shinpachi grunted as he moved his hips back and forth, a bit of semen spurting from the tip of his penis. "Ane-ue's butt... it's more incredible than I ever imagined..." he moaned, completely caught up in the heat of the moment.
Otae blushed at this, her heart fluttering unexpectedly at Shinpachi's words. She smiled softly.
"I don't know why, but it makes me really happy to hear you say that . . . ❤" she whispered, clasping a hand over chest, feeling her heart hammering against her ribcage. A soft moan then escaped her lips. "Shin-chan..." she groaned, "...don't hold back... please, put it in..."
Shinpachi was momentarily taken aback by Otae's words, but his libido quickly overtook any lingering misgivings that he might have had. Taking just a moment to line his member up with his sister's anus, he thrust his dick into her asshole.
Otae squealed in arousal and ecstasy as she felt her brother inch his cock into her ass. He was stretching out her insides with his girth, and the brief pain led her to most unique pleasure as he began pumping in and out with escalating pace.
Shinpachi, meanwhile, was in heaven as he fucked his sister's ass. She was unbelievably tight and hot, and he felt like he could burst at any moment. He frantically rocked his hips back and forth, panting and sweating and grunting and groaning as he thrust in and out of her asshole.
Soon enough, he heard Otae wail joyously, and felt her body shudder beneath him. Her anus clenched tightly, burning up as Tae Shimura came from having her shota-fied brother fuck her ass. It was a wonderfully shameful sensation, and she smiled, lost in euphoria, as all strength fled her limbs.
She collapsed bonelessly, unconscious from exhaustion. Shinpachi, however, was still inside his Tae's ass, annoyingly enough just short of climax. He continued to fuck her asshole, decided that he didn't care if she was unconscious. He kept on thrusting into her ass, and came about five minutes later. Pulling out, he noticed she was still unconscious. Not only that, but his dick was still hard as a rock.
On some level, Shinpachi understood that what he was doing was crazy, but he was too horny now to care. He needed some way to take care of his erection, and in his randy state he found nothing wrong with the idea of going out and fucking whatever girl. He did, however, have at least enough presence of mind to feel uncomfortable about going outside without any clothes on.
Unfortunately, he quickly discovered that they had no clothes which fit him. He had quickly realized, after pulling out of his sister, that he had somehow been shrunk, or perhaps more accurately age-regressed. Although his genitals at least appeared to have been unaffected by the transformation, being the same size as they usually were, even if they certainly seemed larger at first glance in comparison to his shrunken body.
Still, getting back to the matter at hand, Shinpachi could not find any clothes in his present size, and that was a pain because he was not eager to walk around Kabukicho in his birthday suit, even if that prospect did sound more and more appealing the longer he went without any relief for his perversely persistent erection.
However, as luck would have it, just as Shinpachi's patience was reaching its limits, he heard a knock at the door.
The door slid open with a bang, and in walked Shinpachi's fellow Yorozuya with a bag in each of their hands. Gin-san – Gintoki Sakata, the White Yaksha, a former big name member of the Anti-Foreigner Faction who had years given up on fighting a hopeless battle against the Amanto and the Shogunate – looked the same as ever, with his naturally curly silver hair and eyes like a dead fish.
"We're back with the clothes you asked for..." the silver-haired, twenty-something sweets-and-manga-addict drawled dully, looking like he'd rather be anywhere else. "...eh?" he blinked, staring disbelievingly at the sight before him.
Shinpachi Shimura, who had been age-regressed by some strange beam weapon, was standing in the middle of the room with an ego-woundingly large erection.
"..." without saying a word, Gin-san dropped the bag he was holding onto the floor, and then he spun around and walked right out the door past Kagura, who had been outside just behind him.
"Gin-chan?" said the petite fourteen year old Yato girl confusedly. "Where are you going?"
"To get drunk," the wavy haired ronin grunted in response as he departed.
Kagura blinked, staring after Gin in confusion, before deciding to look inside the house.
At the sight of the naked chibi-Pachi standing in the middle of the room with a massive erection, the young Yato lass...
Kagura stared at Shinpachi's erection, finding herself strangely entrance with it. She felt herself become wet as the smell of sex filled her nostrils. As well, Shinpachi pheromones completely permeated the air, and his musk clung to everything.
His scent was heady and overpowering, filling the room. It was addictive, too. In fact, the second Kagura stepped into the room, she was completely under the spell of Shinpachi's enhanced pheromones. She could not focus, feeling dizzy as his scent aroused her. She could not think either, as she walked further into the room, closing the door behind her and dropping the bag of clothes on the floor. Not about anything save sex.
With Shinpachi.
Discarding her clothes, the slender, vermillion-haired fourteen year old strutted up to Shinpachi. The boy was at eye level with her small, barely-developed breasts, and he was surveying her body hungrily, lustfully.
Leaning forward, Shinpachi lightly bit down on Kagura's nipples - first one, then the other. She moaned shamefully at the sensation, her pussy burning up from his touch. She bucked her hips and whimpered, feeling the need to have something inside her.
Shinpachi, nibbling teasingly on Kagura's erect nipples, smirked knowingly. Already, she desperately needed him inside her. How pathetic.
It was a good look on her.
As much as he was enjoying teasing Kagura-chan, Shinpachi's aching hardness hungered for her tight insides. And Kagura's pitiful pleas for him to stick it in and fuck her broke down whatever restraint he might have had left.
Without further ado, Shinpachi began rubbing the head of his dick against Kagura's entrance, causing her to squeal and moan. The lewd, shameful look on the young teen's face as she writhed in ecstasy drove Shinpachi to even greater heights of arousal. His dick throbbing painfully, longing for release, he shoved it in.
It was an incredibly tight fit. Not only was Kagura young and a virgin, but she also had the tough and powerful body of a Yato. Her pussy greatly resisted being stretched, and it squeezed him so hard it almost felt like it could crush him with just a little more force. She wasn't someone you could play around with carelessly.
But Shinpachi pushed on, too addicted to Kagura's tight cunt to care about anything else. Slowly, at first, he pumped in and out of her, sucking and nibbling on her cute pink nipples while he did so. Gradually his tempo increased, and he tore up her pussy with his dick while sucking vigorously on her small tits and even playfully fingering her asshole.
Soon enough, Kagura came, and Shinpachi came too – straight into her, and without even a care.
Shinpachi didn't need to pull out of Kagura to know that he was he still hard, even after coming inside of her. He could feel it just fine, throbbing and aching as hard as ever. It felt like there was a little less pressure, though.
He didn't miss a beat, barely even pausing before continuing to fervently thrust in and out of Kagura-chan.
The redhead mewled cutely, wrapping her arms around Shinpachi, and she looked into his eyes. Although she was fourteen – only two years younger than him – Kagura was just a little bit small for her age, and in his current form Shinpachi wasn't that much shorter than her.
"Shinpachi..." she purred, rubbing herself against him, wanting to feel his skin touching hers as much as possible, even with his cock still inside her, pounding her pussy. She was addicted to his touch, moaning lewdly as she ground her hips against his. "Shinpachi...!"
The shota-fied Shimura smirked, loving the feeling of having the willful young lass turning to putty in his hands. He smacked her firm, round little ass, and she moaned lewdly. He drilled her cunt, and her body melted into his.
Kagura came several times as Shinpachi fucked her, splattering her nectar all over his pelvis. Her skin was flushed and sweaty, eyes rolling up in her head and tongue lolling out of her mouth as he nailed her. And he came a couple more times too, himself, before finally coming to a stop and pulling out of Kagura.
Kagura pouted when Shinpachi pulled out of her, whining softly as he stepped back. Her pussy was drenched, and she still felt a burning ache in her loins.
"Shin-chan..." she whimpered, looking at him with such a pathetic expression, "Don't stop... I need it... Please, I'll do whatever you want... just give me more, please..."
Shinpachi chuckled at this, a sadistic gleam in his eyes, light shining off his glasses in an almost menacing manner.
"Ohhh?" he said. "You'll do whatever I want? Even walk down the street in a short skirt with no panties on a windy day? Even wear a collar and be led around by a leash like a dog? Even give me first dibs on food, and let me eat all my meals off of your naked body? And even suck me off, or fuck me, at any time, and any place, no matter what?"
Kagura nodded eagerly, her pussy visibly getting even wetter. She was shameless in a lot of ways, and oftentimes not even remotely feminine, but she had her cute points. And she was obviously earnest about this, if she was willing to even do something like giving Shinpachi first dibs on food.
And Shinpachi smirked, pleased by this turn of events.
"Then from today on you are my slave, and you will call me 'master'," he told her, before smirking and saying, "Now... what should I have you do first?"
As Shinpachi contemplated what to make Kagura do first, he was struck with inspiration.
"Kagura-chan..." he said, grinning wickedly at her. "Your first order as my slave... is to get on all fours and bark like a dog!"
Kagura smiled brightly, eagerly complying.
"Arf! Arf!" she barked, crawling on her hands and knees. She was panting, her tongue hanging out of her mouth, and she even waggled her cute little behind for her new master.
Shinpachi laughed at the sight of the girl acting like a dog. He patted her on the head, teasingly ruffling her hair. Then he smirked when he noticed her eyes zeroing in on his cock, staring longingly at it.
"Does Kagura-chan want a treat?" Shinpachi asked Kagura condescendingly, putting a hand on his massive rod and talking down to her like she was a lower form of life. It was an odd sight to see, not that there was really anyone there to see it.
She nodded her head though, eagerly salivating at the thought of getting a taste of her master's cock. Chuckling, Shinpachi gave her to go ahead, and Kagura immediately began sucking on his meat. She only fit about the first quarter of its length into her mouth, but she didn't let that deter her from enthusiastically suckling and licking at it.
Kagura was delirious with pleasure at the taste of Shinpachi dick in her mouth, and she played with her nipples as she zealously sucked her master off. He came inside her mouth shortly enough, and she swallowed every last drop with relish. She did not stop sucking him off at that, but rather kept going, pushing him to climax many more times, voraciously swallowing every drop of his seed.
They went at it like this for nearly an hour, Kagura sucking up as much of her master's milk as she could stomach – and with the almost bottomless appetite of a Yato, was no small amount. Eventually, pulled out of Kagura's mouth and ordered her to stop. She pouted at this, but he told her that if she wanted any more of his seed, she would have to earn it.
Of course, he could have let her suck him off til the end of days, for how great it felt, but he wanted her submissive and compliant – it wouldn't do to give her everything she wanted right off the bat, not if he wanted her completely at his mercy (he could be surprisingly sadistic when given the chance).
"How about you eat out Ane-ue?" Shinpachi said to Kagura. The young girl's eyes widened at his suggestion, and she blushed at the thought of doing something like that with a girl, let alone Otae, whom she looked up to and admired.
Shinpachi smirked at the look on Kagura's face, and he took her by the hand, leading to where his sister was lying on the floor unconscious from being fucked in the ass by her little brother. Kagura's blush deepened at the sight of Otae's sore red buttocks and abused, stretched out asshole. She licked her lips nervously, seeing the dried semen that was encrusted in Otae's asshole and buttcrack.
For a moment, Kagura considered licking Otae's ass clean first, but a sharp swat on the behind from her diminutive master changed her mind, and she proceeded to effortlessly turn the older girl over onto her back. Then she got down on her hands and knees and bowed her head so that her nose was practically all but enfolded in Otae's pussy.
She inhaled the scent of Tae's womanhood, smelling the perfume arousal still lingering in the young woman's pussy. Kagura let out a moan, smelling not only Otae's sex, but traces of Shinpachi's as well. Overwhelmed with arousal, she began hungrily licking the older girl's cunt. Kagura buried her face in Otae's pelvis, her tongue plumbing the recesses of her pussy, teasing the sensitive folds and clitoris.
Otae moaned in her sleep, weakly wriggling as Kagura ate her out. She soon came from the stimulation, and Kagura eagerly lapped her nectar up, swallowing it all with a smile.
Shinpachi watched the spectacle with a broad grin, cheerfully jerking himself off. Soon enough he came, spurting his seed onto Kagura's butt and lower back. Kagura moaned and came too, driven to ecstasy just from the feeling of her master's seed landing upon her skin.
Otae let out a moan, feeling someone licking her cunt. She was lying on her front, so she could not see who it was, but at the moment all she could bring herself to care about was getting off. So she reached down, and groping for a few seconds at empty air she managed to find the back of the head of the one eating her out, and so she pushed them further in, greedily pressing their face against her pussy as hard as she could.
She heard a muffled moan as she did so, and she recognized the voiced, even muffled as it was by a faceful of her privates. The knowledge that it was Kagura, her brother's cute little coworker, who was eating her out only turned Otae on even more. She groaned and panted as she humped Kagura's face, even as the girl eagerly licked her cunt.
With another, louder, moan, Otae came with a shudder. And since Kagura's face was pressed full-on against her pussy, nearly every last drop of Tae's juices wound up in Yato girl's mouth. And Kagura drank it all up greedily, savoring every ounce.
And Shinpachi, watching this, masturbated furiously, coming several times all over Kagura's nubile young body. And his seed seemed to have an aphrodisiac effect on the girl, for she became visibly more aroused every time he did so.
But masturbating was not enough to relieve his desire, and soon Shinpachi went around his big sister and, grabbing head by her hair, he roughly slammed Otae's mouth down on his cock, and he forced her to deepthroat him, violently fucking her mouth while Kagura ate her out.
Tae loved this treatment, and she soon came with even more force than before from the delightful shame of having her face raped by her little brother. And Shinpachi came also, forcing his sister to swallow every last drop of his semen – though she would have gladly done so anyways – before pulling out and letting go of her head.
Still feeling like playing with these two some more, Shinpachi once again walked around Otae and went to Kagura, who was still licking his sister's pussy. Then he bent over her and positioned his throbbing member at the young girl's entrance, causing her to whimper delightedly at the contact.
With a grunt, Shinpachi thrust himself inside Kagura's wondrously tight cunt, causing her to moan lewdly into Otae's crotch. He drilled her pussy without mercy, repeatedly slamming himself into her with as much force as his body could muster – which was not an insignificant amount by any means.
Shinpachi fucked Kagura raw for several minutes, the girl writhing and wailing in ecstasy under his coarse ministrations. He abused her small tits and puffy nipples, sucking and biting and pinching and tweaking, and smacked her ass until it was red, treating her as roughly and violently as he was able.
And Kagura loved every second of it.
Eventually, though, after several minutes of using and abusing the Yato girl's body, coming inside her pussy a number of times, Shinpachi once more turned his attention to his sister. With a smile he went into Otae's pussy, causing her to whimper and yelp oh so cutely, and began to fuck her next.
He gave his sister the same treatment he'd been giving Kagura, perceiving that she wanted it. Pounding her cunt, spanking her tits, fondling her ass, he thoroughly molested and mistreated his sister, causing her to come hard and often. And he came inside her a number of times as well, filling Otae's womb with a voluminous quantity of his seed.
After a few minutes of this, however, there was a sudden sound from the ceiling, and with a great CRASH and cloud of dust, a certain someone fell straight down into their midst. To no small surprise, Shinpachi saw that it was the full-figured, purple-haired, glasses-wearing, masochist kunoichi Ayame "Sacchan" Sarutobi, and she was half naked, one hand on one of her tits and the other at her crotch.
"Ahh, hello, Sacchan-san," said Shinpachi airily, smiling down at the woman. "You look awfully busy," he said, leering at her like she was a piece of meat.
Sacchan's face grew redder under his gaze, and she let out a moan, coming under the young man's gaze. She had not meant to be found out – indeed, she had initially only come here to follow her darling Gin-san – but she had been turned on by the sight of Shinpachi using Kagura and Otae, and her inconveniently high libido had resulted in her masturbating in the ceiling while spying on them.
It had not been her best idea, admittedly, but then lying there under the smirking scrutiny of the age-regressed Shinpachi she found she did not really care. She had long been a very kinky woman, and was very much into sadomasochistic play, and having the young boy (with a godly cock, judging by Kagura and Otae's earlier screams and moans) leering down at her, easily able to see her bare breasts and the soaked crotch of her outfit as she continued to masturbate unperturbed by the fall, was turning her on more than she could remember ever having been before.
She soon came again, and looking up into Shinpachi's eyes, she said, "Hello, darling..." in a very lewd tone of voice, not even noticing the slip of her tongue. But Shinpachi did.
"Ohhh?" said the Shimura boy, giving Sacchan a smirk. "But I thought Gin-san was your darling," he said condescendingly.
Sacchan whimpered, moaning in spite of herself. "Y-yes..." she said. "...er... I-I mean, no...! He... I... you..."
Her blush deepened, and she trailed off, letting out another moan as she pinched one of her nipples, pushing herself again to the point of orgasm. Her eyes lingered on Shinpachi's member, which was erect and covered in the juices of both Kagura and Otae, and she unconsciously licked her lips as thoughts ran through her head of being abused by it and forced to worship it, and she let out a deeper, huskier moan, frantically thrusting her fingers in and out of her pussy, the motion causing her shorts to slide down.
Shinpachi, with a chortle, pulled Sacchan's shorts the rest of the way down, completely exposing her nakedness and shame for any to see. She squirmed pitifully, feeling her body burning up from the boy's gaze on her pussy. She wanted him badly, such being the potence of Shinpachi's musk that already she had all but forgotten her devotion (bordering on obsession) to Gintoki.
"I suppose you three will want to have your wicked way with me, now..." Sacchan murmured, looking the exact opposite of afraid at this thought.
Rather, she appeared to be inviting them, squeezing her breasts together as she covered her nipples with her arm while pressing her other hand against her pussy, wiggling her hips and biting her lips as her eyes lingered on Shinpachi's rod. Her face reddened deeper as she saw it twitch and throb, and she was breathing heavily and covered in sweat.
Otae smiled wickedly at this, leering down at the half naked assassin. "Ohh?" she said. "Does the fat ugly slut who was spying on my cute baby brother (andmasturbating over him) think she's actually worthy of his cock?"
As she said this, she took part of Ayame's kimono in hand and tore it, shredding the fabric as she ripped it off. Sacchan whimpered lewdly as Tae continued to insult her and tear up her clothes, her pussy growing hotter and wetter the more she was abused in this manner.
"No...!" she cried out at last. "Ohhh... I am not worthy of it... I am just an ugly cow, a dumb worthless slut who can't do anything right!" she moaned as she rubbed her nipples and pinched her clit. "I'm not even worthy of licking his semen out of the dirt!" she said, coming with a shameful cry.
Otae smirked. "Good," she said, before violently grabbing one of Ayame's tits and squeezing hard enough to leave a mark. "As long as you know your place, I suppose we can deign to at least give you the honor of raping you."
Kagura looked into Shinpachi's eyes for approval, before going forward and following Otae's example. Bending over, enticingly waggling her tight little ass at her master, she started enthusiastically slapping Sacchan's other tit. Then she leaned forward and whispered into Sacchan's ear.
"This is too good for you, yes~?"
And she then pinched Ayame's nipple between her thumb and forefinger, and sharply twisted it, causing the legally blind kunoichi sub to scream in pleasure.
"Yes! Yes! Oh god, yes! It is! This is too good for a filthy whore like me!" she cried out shamelessly, writhing lewdly under the abusive ministratitions of Tae and Kagura.
As one, Kagura and Otae smirked, and they looked back at Shinpachi, happily and seductively shaking their booties at him.
Shinpachi chuckled, and he shook his head with a small grin.
"You girls are incorrigible," he said, before stepping forward and giving both Tae and Kagura a playful swat on the ass, causing them to squeak and giggle delightedly.
"Yes we are, master!" Kagura squealed, eagerly rubbing her rear end against his hand.
"Indeed," Otae purred in agreement, smiling lustily at the kunoichi slut beneath her and Kagura.
While the two girls continued to molest Sacchan's tits, Shinpachi took hold of the bespectacled masochist's hips and lifted them up to his waist-height. Then, not even bothering to do any foreplay, he rammed his rod into her, tearing up the slut's cunt with the sheer girth of his manhood.
Sacchan's eyes widened behind her spectacles, and she let out a loud, lewd wail. Her cheeks were flushed, and she was already drenched. Thanks to how observant she was in keeping up in certain special kunoichi exercises, Shinpachi's monster cock reaming her pussy did not hurt as much as it might have, although that was not to say there was no pain at all.
Moaning, Sacchan writhed ecstatically as her master thoroughly pounded her, formaster she was now indeed calling him, at least when she was able to form any coherent words at all. Her pussy was burning up and gushing nectar, and if her breasts were leaking a bit of milk as Kagura and Otae abused them, well it was quickly licked up by the two girls.
Shinpachi used Ayame Sarutobi like a two dollar whore, insulting and abusing her as he fucked her cunt raw. The girl loved every second of this treatment, and her orgasms were both intense and frequent. And he came inside her a couple of times, at least, before finally pulling out.
Semen spilled out of Sacchan's pussy as Shinpachi stepped back, and her ass fell back onto the floor with a loud THUD when he let go of her hips. Otae and Kagura looked up from gnawing and sucking on Sacchan's tits.
"Have you already had your fill, master?" asked Tae huskily, making bedroom eyes at her little brother as she seductively licked a bit of milk from her lips.
"No, of course not," said Shinpachi, "I could rape this slut all day—" (and Sacchan moaned happily at this) "—but I think... I think I hear someone at the door," he concluded, and the girls perked their ears curiously. To their surprise, they did hear someone at the door, and Otae agreed to answer it.
Walking up to the door and swaying her hips for Shinpachi's viewing pleasure as she did so, Otae answered the door wearing a pleasant smile, and nothing else. Her small breasts were nonetheless looking very perky as she did so, and her sweat-slicked skin glistened in the sunlight that poured in.
"Hello~" she said brightly, cocking her head to the side as she smiled just little bit wider. "How are you, Oryo-chan?"
Oryo, a young woman the same age as Tae, and a fellow employee of the cabaret club Snack Smile, stared wide-eyed at the eldest Shimura child. She had short, light brown hair and eyes of the same color, and she was dressed in a pink kimono that tastefully emphasized her modest curves (more generous than Kagura's or Tae's endowments, at least, although not extraordinarily so).
"Oh! I-I-I'm s-sorry...!" Oryo anxiously stammered out, clapping her hands over her eyes as her face went beet red. "I didn't know you were... Sorry, Tae! I didn't mean to barge in on you...!" she babbled nervously, overwhelmed by the fact that her friend had answered her front door naked as a jaybird, and seemingly without a care in the world.
Otae giggled demurely, and she took one of Oryo's hands into hers.
"No need to apologize, Oryo-chan~" Tae chirped cheerfully. "You're always welcome to visit."
Oryo blushed at this, and she shyly averted her gaze from Tae's, caught off balance as she was.
"W-well, I wouldn't want to impose..." she murmured nervously, trying to ignore the fact that Otae smelt heavily of sex, and that she could hear faint moans coming from inside.
"Oh, but I insist," said Otae, and she dragged her friend inside with a smile on her face, not bothering to close the door as she led Oryo to where her master awaited.
Oryo, who had been weakly, exasperatedly protesting being dragged inside, went suddenly silent and stared in disbelief at what she now saw.
A pretty buxom woman with light lavender hair (likely around her and Tae's age) was lying on her back, stark naked. A nude young girl with vermilion hair and pale, nearly translucent skin was crouching on all fours and enthusiastically eating the woman out, gleefully wiggling her firm, tight ass in the air as she did so.
But that was not what caught her attention. No, what ensnared her was the sight of a young boy, bearing a striking resemblance to Otae's little brother in his youth, straddling the lavender-haired woman's sternum and pumping an impossibly massive cock in between her full, round tits – which upon closer inspection were shown to be covered in violently-colored hickeys and bite-marks, as well as a fair quantity of thick, strong-smelling semen.
Oryo's face flushed as the potent scent of the boy's sex invaded her nostrils. She did not notice when Otae let go of her hand, nor when she started undressing her. So enraptured was Oryo with the sights and sounds and smells of the boy and his girls (for somewhere in her mind she knew that they were indeed his, in every way), that she was rooted to the spot. Even when she had been stripped of her very last article of clothing, Oryo did not react, simply staring at the boy and growing more perversely aroused with each passing second.
After what felt like an eternity, the boy came with a grunt between the woman's breasts, and her cleavage overflowed with his seed. Apparently finished, he turned his head at least and beheld Oryo, standing before him, as naked as the day she was born, her cheeks flushed and her pussy wet.
He smiled at her, and Oryo felt herself go weak in the knees.
The sight of the boy's nakedness, as well as the heady aroma of his sex, overwhelmed her. She staggered, feeling woozy. She felt herself get hot.
Oryo moaned. Shinpachi's pheromones were going to work on her mind. She found herself wanting nothing more than to be used by him, to be fucked and abused by him. She didn't even recognize this boy, but that didn't matter.
She got down on her back, horny and aching for release. She spread her legs, then the lips of her pussy.
"Make me yours," she begged him. "Turn me into your slut as well."
Shinpachi eyed Oryo's naked body appraisingly as the girl laid down and presented herself to him. She had a nice, tight-looking pussy, long, smooth legs, and neatly trimmed pubic hair. She was spreading her labia, desperately exposing her cunt to him.
He hummed thoughtfully, glancing also at Oryo's decently shapely hips and creamy white thighs. She had a fine body, with an ass that was one of the better moneymakers at Snack Smile, as well as perky, shapely breasts and face that was pleasant to look at. All in all, Oryo was easy on the eyes, and she had a body that was just begging him to make her his slut (even while her mouth was doing the exact same thing).
With an approving nod, Shinpachi made up his mind. Gesturing for his three sluts to stay back, he went up Oryo and came in unto her, so to speak.
Shinpachi rammed his rod in Oryo's womanhood, pumping in and out of her, slowly at first, but gradually getting faster and harder. He took one of her nipples into his mouth, licking and sucking one breast while using his hands to grope and fondle the other. Oryo tasted sweet, and her pussy was hot and tight.
Oryo moaned as he pounded away at her, ecstatic at what he was doing to her body. He was making her feel incredible, filling her with a sense of complete euphoria as he pleasured her and used her for his own pleasure. His cock was unreal, and her pussy was on fire as she came again and again from his ministrations, and he came into her many times as well.
Oryo squealed, feeling her womb filled up with his seed, and she smiled adoringly at him. Wrapping her arms around Shinpachi, she begged for a kiss. He complied, but he was merely humoring the girl; even with the passion he put into the kiss, it was to him only a means of controlling her further, of sealing her addiction to him.

A/N: This is something from a WDC interactive I worked on ages ago. I haven't read Gintama in forever, and this will probably just be a standalone oneshot, considering the immense unlikelihood of me ever continuing it. But, eh, I figure maybe somebody will enjoy this weird-ass smut.
