"I should probably go into more details about this technique before we proceed with our rescue efforts," Ino Yamanaka explained, looking to Hinata Hyuuga and Sakura Uchiha, the three talking over a drink. They met at Ino's place, granting them some privacy and letting them discuss the personal details that came from her clan's hidden technique. Both Sakura and Hinata looked quite piqued, intrigued by what the details might be, mainly if there's anything dangerous about utilizing the secret process. "Officially called Jikan no Mondai, this technique will send your mind to a shared, alternate timeline, where you should be able to find Naruto. Due to how this will work, any changes you make to this similar timeline won't impact our own, but it will change the course of events for the alternate timeline. So, I still recommend a word of caution, for their sake." Ino explained, offering the information she held from generations of her family testing out this hidden technique. She explained the simple information first to give the two women a basic understanding of how it worked; unfortunately, she eventually had to explain the dangers.

"There are potential personal consequences to doing this," Ino began, Sakura cocking a brow in response to this implied danger. She, as well as Hinata, wanted to know what exactly could happen to them. Knowing that information might lead to some hesitation or natural caution regarding the mission in front of them. "Let me first say the most hazardous of the consequences: if anyone using this technique - even Naruto - dies in the past, his mind will not return to his future vessel. He- We… will be dead, for good." The blonde said, laying down the cold, harsh facts of what could happen to them. Dying would be the death of the future mind and past mind, both versions of being killed off at once. Death would not be an escape. "So, not even his past death would send his mind back to us?" Hinata asked of her husband, Ino nodding to acknowledge that sad fact. If they didn't convince him to go back to the future, the original timeline, Naruto would likely be gone forever. Ino then looked as if suddenly remembering something- a notion that had to be mentioned while discussing unfortunate truths of the situation. "More of an inconvenience than anything, we have no way to know where- err, when, Naruto has gone. When you use the technique, you choose when you go, so you may end up at a point on their timeline before Naruto arrives. If that's the case, I recommend playing along until you know it's him."

Sakura and Hinata had shared glances as they looked toward each other, finding these warnings somewhat concerning. The women could understand now why this technique was such a secret, given the dangerous ramifications that could come out of it. A person's body and mind could be killed suddenly, leaving their future body a decaying corpse; it was like dying in one's sleep, in how sudden it could happen. That, and the lack of consciousness. "And, if I know Naruto, he's no doubt causing trouble in this new timeline. Not even considering the consequences of changing a world's history." Sakura spoke bluntly as she presumed it would be rather obvious. The loud-mouthed jinchuuriki wasn't known for being very intelligent, so it wasn't too hard to piece together that Naruto would revert to his more annoying ways. However, all of this information left the women skeptical of whether they should be getting involved in this messy situation. They could always have Sasuke take over, becoming the Eighth Hokage, and suggest Naruto had to resign for important business. A very weak excuse, but one that was probably easier to do. And much safer for the women.

. . . Back in the Alternate Timeline . . .

Sakura's training continued, with the jinchuuriki trying his best to make the most of his remaining time before the years of training with the Sannin Jiraiya. However, the focus of Sakura's training had been evolving over the coming days. At first, Naruto merely wanted the young pinkette to accept her role under the guise of maximizing her training. Or, as he put it, to continue her training. So, perhaps, it was a sort of blackmail, considering she had no other choice if she intended to continue becoming Sasuke's perfect woman, but Naruto doesn't care for semantics. The important part was Sakura recognizing her place as the blonde's cock-holster. For the most part, the training took place in privacy, where Sakura or the future-Hokage could be as loud as they wished. That setting was truly ideal, as Naruto hoped for Sakura to lust for that wild, raunchy sex that only he can seem ably give her. But, of course, after a few private practice sessions together, Naruto was starting to branch out, taking Sakura to much more open, public places.

In particular, Naruto decided to take Sakura with him to visit the hospital, where the two took the time to visit Jiraiya. It is almost like Naruto's way of rubbing Sakura in his sensei's face; the perverted Sannin met the pinkette, blissfully unaware that the blonde was doing all the depravities he wanted with her. Everything Jiraiya likely desires to do with the women he googles. Still, doing that wasn't necessarily the point of their visit; it was something Sakura would realize for herself soon enough. When they first entered, the pervy-sage smiled as he looked at Sakura, thinking that the girls of this generation must be fast-growers, having no idea that Sakura's maturation was all done by the jinchuuriki. Jiraiya looked to Naruto with a soft smile, asking the blonde, with a very sly grin: "Nice of you to visit again, kid. Whose this? Your girlfriend?" Naruto played along with Jiraiya's teasing, nodding. Until Sakura punched the jinchuuriki in the arm, causing a slight yelp to escape the blonde's lips, feeling a bit of soreness. Not that he could expect much else from the girl who one day serves as Tsunade's student; Sakura had some decent strength even before learning to enhance her raw power with chakra. "Like hell I am! We're just… nnnnngh … friends!" Sakura answered, biting her lip to suppress some odd noises in front of the Sannin.

Unbeknownst to the pervy-sage, Sakura had a vibrating plug stuffed up her tight, rarely-used asshole while standing in Jiraiya's room. And, whether for fun, or revenge for the abusive punch, Naruto activated the device part way through the pinkette's response. Sakura could feel her legs uneasy as the device stirred within her, the jinchuuriki coyly reaching to her rear to cup her firm ass-cheek, eyes fixed over on Jiraiya. "Yeah, sadly, just friends. We came to see how you're doing, pervy-sage!" Naruto explained, noticing Sakura taking some uneasy breaths, her face turning a light blush. He couldn't tell if it was an embarrassment, arousal, or both. He knew that Sakura had to be careful if she didn't want to get caught. The silver-haired Sannin was suspicious of this but didn't say anything. At least, not just yet. "I'm doing as well as I can be, I guess. How did that meeting with our Fifth Hokage go?" Jiraiya had asked, recalling Naruto mentioning visiting Tsunade in his prior visit. The blonde genin smirked when asked about that, casually molesting the soft, cushiony ass-cheek of the pinkette, toying with his toy as she struggled to keep up a calm facade.

"Well, I know I said I wouldn't, but I convincedher to re-evaluate your case. And, it looks like she'll be willing to try and treat you. Perhaps with a greater chance of success." Naruto explained, purposefully leaving out the important details, like how he convinced her to do all of this. Not that he'd yell that all out in front of Sakura or his other targets. They were supposed to only learn from each other at the last minute. When they were already so broken that they wouldn't care less about who and how Naruto targeted them. Jiraiya felt a mix of emotions at that moment, both thankful for what Naruto supposedly did and annoyed that the blonde didn't follow his instructions. "Well, Naruto, it seems I owe you my gratitude. I just hope you didn't do something crazy to help me." The silver-haired Sannin had explained, having zero clue how the blonde changed the Hokage's mind. And as the two shared a smile, Sakura had just been busy focusing on holding in any moans or displays that might give her away.

Looking over to Sakura, the blonde genin knew he had to wrap things up even if it was enjoyable watching the pinkette squirm in this situation. "Well, I think I'd better get Sakura home. She doesn't look too well." Naruto explained, moving his hand off her rear, finally, as he turned to face the doorway. Jiraiya smiled, nodding, shifting his eyes to look at Sakura, eyeing her up and down, as he started trying to piece together what exactly was going on. He still says nothing about it, as if to keep Naruto's secret; he merely waves goodbye as the two squadmates walk out the door, telling Naruto: "Come see me before my operation if Tsunade tells you when it is." The jinchuuriki presumed it was a detail Jiraiya wanted him to know, should the pervy-sage die during the operation, like the fact that Jiraiya was Naruto's godfather. Regardless, Naruto considered it, taking the anxious pinkette by the hand, leading Sakura somewhere. However, in particular, the location was, despite Naruto's words, not Sakura's home; instead, Sakura was brought to an empty hospital room across the hall from Jiraiya's room. The blonde genin had shut the door, turned out the lights, and closed the curtains after taking Sakura to the bed in the room.

Naruto would smile toward Sakura, the kunoichi continuing to stifle her moans; she hoped to do this somewhere more private but knew arguing with the blonde would be useless. The future Hokage had a growing influence over her, and even the pinkette could feel a sense of arousal at their more public romp. Sakura was breathing heavily, raising her ass, not wanting to risk putting the vibrating dildo deeper within her asshole. With all that she felt just from it being lodged in place, she didn't want to imagine the ecstasy she'd get when it throbbed against the furthest depths of her anus. "The… fuck were you are thinking, you knucklehead? Did you want to get caught?" Sakura asked, her voice sounding rather ragged, finding it difficult to talk and suppress moans simultaneously. The blonde genin shrugged, honestly not caring too much if their arrangement was discovered. He was beginning to feel the damage was done, and Sakura would never escape their ongoing relationship. It sounds a lot worse than it is. But, Naruto could see that, despite her complaints, Sakura was incredibly aroused, something that brought a look of satisfaction to his face. The blonde waltzed over to Sakura with a grin, placing a kunai down on the bed beside the pinkette's sensitive body. Then, he'd simply say with a knowing glance: "You know what I want you to do."

Sporting a hesitant expression on her face, the kunoichi gripped the kunai and slowly lowered her rear onto the bed, as it would make the next step quite easier. Unfortunately, as her ass pushed down against the mattress, the pinkette felt that vibrating dildo slide deeper into her asshole, the tip of it now vibrating against her furthest depths, her body's excitement only growing as she felt something akin to a shock throughout her body. Luckily, Sakura kept a hand over her mouth, the ensuing sounds of ecstasy becoming muffled as they escaped her lips, only to be rendered incomprehensible. She knew her body would react like this, having come to expect her maturing body's sense of arousal only become more potent after every training session with Naruto. When she found herself able to have some level of control, moments later, the somewhat calmed-down Sakura proceeded to do what Naruto expected of her: using the kunai, she cut heart-shaped holes over where her nipples would be, letting the center of each breast poke out of the fabric of her top; similarly, the kunai was also used to cut a sizable hole from the pinkette's spats, allowing direct access to Sakura's needy holes.

Naruto had merely smirked with that finished as he eyed the delicious display that the kunoichi put on for him, just as he liked it. In his eyes, it was the perfect look for someone who would be a cumdumpster; though, in the future, he'd likely fit her with clothes that have those sections removable, so tearing up her clothing won't be necessary every time they have their fun. "A fitting look for my cumdumpster," Naruto said with a wide grin, watching as Sakura raised her ass once more, allowing less pressure to be placed on the far point of her anal passage. With the hole in her spats, he could easily witness her eager, gaping asshole and the vibrating toy lodged within it. As they both were seemingly aware by now, this training was supposed to be about public fun and anal sex, two things the blonde believed crucial for Sakura to adapt to. The humiliation of serving in public places, and using all of her assets to serve Naruto, were very important. The future Hokage wasn't solely interested in breeding-Esque vaginal sex; he intended to train his cumdumpsters in all areas. And, he figured it was about time to get Sakura into anal-play.

"I think you've kept me waiting long enough! This thing has been driving me crazy!" Sakura whined, referring to the vibrating, faux cock pulsating in her asshole. She was used to Naruto's cock, and other toys filling up her eager pussy. She's even had toys lodged in her tight asshole before; it was just, this time, that something felt different. It might've been there using it in public, Naruto's teasing, or the fact that she knew that all of this was coming. Whatever it was, she couldn't shake this intense feeling she had about what was to come. "No, no, Sakura. You know what I need to hear before we do anything." Naruto reminded her, the pinkette's face turning a deep red. A look of humiliation, shame, and embarrassment as she remembered what the blonde required of her. Biting her lip, she finally gave in to the blonde's call for obedience, shaking her stuffed asshole in front of Naruto as she said a generalization of his required decree: "I live to serve as Naruto's cumdumpster! Please use me as much as you want, and stuff me full of your seed! I'm just your… nnngh … cock sleeve, so don't hold back as I milk your huge dick!" As Sakura spoke that declaration, it had - despite her hesitation - been good enough for the blonde shinobi, who could feel his cock throb and ache under his orange pants.

As a show of her upcoming reward, Naruto smirked, dropping his pants to the floor as he let the pinkette witness his fully-erect cock and packed balls, eager to give Sakura what she desired. And, as she tried not to stare with her cock-hungry eyes, her increasingly-moist pussy and teased asshole were giving her away. The exterior of Sakura's asshole seemed to move in response to Naruto's undressing, and her cunt looked as though it wanted so special attention. Her body had very clearly been craving the blonde's touch and penetration, something even Sakura was beginning to admit to herself as much as it bothered her. "Well, before we give you your treat, I suppose we've gotta get that out of you… But, before I remove it, we should take a few precautions!" Naruto explained, searching the room for a few minutes, putting together a set of materials that would have to work for what the blonde intended to do. Using some spare bedsheets, the blonde genin fashioned together a blindfold, leaving Sakura blind to the events around her; he also used other fabric to create makeshift binds, pinning the pinkette's hands to the bars on the side of the hospital bed. The only problem, at first, was creating a gag to put in Sakura's mouth, but - since this was a hospital - the room thankfully had a gag. If Naruto had to guess, it was something used to keep people from biting their tongue during painful procedures or other such uses.

"What the mmmmmffff ?" Sakura tried to ask, unaware of this plan of Naruto's, both scared and aroused by what he might be planning to do to her. The lack of her senses, unable to see where the blonde was or when he might remove or insert anything, was like a thrill ride. So, whenever Naruto decided to act, it felt like its own little surprise. That's precisely why, minutes later, Sakura felt a mixture of moans and groans attempt an escape from her lips as the blonde genin forcibly reached into the pinkette's asshole, pulling out that dildo all at once, providing no warning whatsoever. The removal of the vibrating dildo made her lose control of herself for a bit, struggling against her bindings as her asshole remained open long after the penetration had left her. Naruto was quite impressed as he looked at her gaped anus, the retrieved dildo being moist as her damp asshole had been snugly clenching the foreign object. He was almost going to give her a warning about her next penetration but didn't want to ruin the moment; plus, Sakura was still reeling from that forced removal of the vibrator at her current status. But, he did at least wait for the pinkette to calm down, wanting an authentic reaction to what he was about to do; if he did it while she was still responding to the vibrator's removal, her reaction wouldn't be as legitimate. The blonde wanted the experience free of outside variables, to put it another way.

Not long after she displayed a more relaxed demeanour signals, Sakura could feel the familiar sensation of Naruto's thick, huge girth breaching her insides. Of course, it wasn't possible for her to mistake his cock for any toy at this point; the blonde purposely gave her toys that were smaller and less refined than the future Hokage's member. As it entered her infrequently-used asshole, the pinkette's mouth and pussy began to water, liquids escaping both lips as the heavily-desired fuck rod began to dig away at her insides. She felt as though she'd been waiting for the longest time, and that satisfaction had finally arrived. Like her eager, cock-thirsty cunt, Sakura's asshole was beginning to alter its shape to suit its new owner- the very same person's cock that had been making a cumdumpster out of this kunoichi. Each slam away in the pinkette's asshole resulted in more stifled, muffled moans, sounds that boiled down to Sakura pleading for more. She would be begging for the blonde to go harder, get rougher with her, and fill her to the brim like the good cumdumpster that she is. Naruto, facing the kunoichi's blindfolded and gagged face, couldn't exactly see Sakura's facial expression. But, as her muffled moans escaped, he knew just how the kunoichi felt, even if she dreaded to admit it when she had a better grasp on her senses.

The future Hokage decided, after the surprise penetration, that he would gradually lower the restrictions he placed on Sakura, starting by removing her blindfold. As he did, the blonde smirked as the pinkette's eyes appeared to be rolling upwards, losing herself to the pleasure that the jinchuuriki was giving her. Deep down, Sakura either loved the idea of public sex, having Naruto pound away within her asshole, or both. Her words, while still muffled, were generally unnecessary; the way her eyes moved showed the absolute bliss Sakura felt while her asshole was ruined. That is, ruined for other men. This personal bitch to the future Hokage would have her body made to satisfy Naruto, with significantly less consideration given to the others like Sasuke. "Well, my little cumdumpster, I hope you're ready to take my first load!" Naruto warned, feeling the pinkette's asshole only tighten as if to say she had desperately wanted the huge cock to fill her to the brim. That, or Sakura didn't want to release his cock, craving the sensation that came with her hole being filled by Naruto's fuckstick.

With zero ounces of shock, Naruto watched as his precious cumdumpster climaxed from the merciless poundings she received, the blonde making true to his promise as he filled her asshole to the brim. As he emptied his balls, releasing a sizable load of his seed inside her rectal cavern, the blonde genin kept his cock within Sakura for some time, using his girth to plug her asshole, keeping his thick, sticky cum inside her. Their shared orgasms had sent waves of pleasure throughout Sakura, and her mind was dazed as she tried to process all of it, though, like Naruto, she wasn't satisfied with just a single go of things. Instead, they both craved more, which Sakura made clear moments later. After removing his cock from Sakura's asshole, the seed began to pour out of her gaping hole, her pussy soaking wet in excitement, almost as if to challenge Naruto to give it attention. While that may not have been completely clear at first, when the blonde genin removed the pinkette's gag, Sakura clarified: "I'm not even close to being satisfied with just that, Naruto! I don't care if I get pregnant- Thrust that cock into my perverted pussy, and fill me to the brim with more of your cum! And make sure you stuff my throat with that delicious cock, too! Paint my insides, so I can be a good cumdumpster!"

Naruto nodded in agreement with Sakura's words with a smirk, having planned to do just that. Maybe not as soon as right now, but it would happen eventually. It was becoming increasingly clear that her training was going very well; the only thing he wondered was how she would handle everything after today. Of course, she could simply backtrack, saying it was the heat of the moment, or, more appropriately, she accepted her feelings, becoming a better cumdumpster. "Oh, that won't be a problem at all," Naruto answered, making sure the pinkette laid back on the bed, her arms still bound to the railings of this hospital bed. When the insatiably-horny kunoichi had been in position, Naruto stepped back from the bed, performing Kage Bunshin No Jutsu, otherwise known as the Shadow Clone Technique, a Ninjutsu technique the blonde was known for. Thanks to the Tailed-Beast dwelling within him, he could handle a technique like this, even when he had trouble making regular Clones in the academy. The technique allowed him to conjure a Shadow Clone, a chakra-composed duplicate of Naruto, who could use ninjutsu and even help out during this training. And, through trial and error, Naruto learned any secretions released by the Shadow Clone still exist after the Clone has been dispersed. Very helpful in the blonde's fun, as any creampies a Clone might don't disappear.

Sakura had been rather thrilled by the appearance of the equally-hung Shadow Clone, grasping an idea of what Naruto had intended. She watched the real Naruto and his Shadow Clone- she thought of it as Naruto - discuss the course of action. As the pinkette eagerly awaited the Narutos to make their move, she, in her lustful mind, began to entertain the thought of a huge group of the blondes, all ganging up on the mature-bodied Sakura. She knew she shouldn't be thinking or talking like a slut, but couldn't help herself, what with her desires flaring up. She considered this to be a role she was filling; she didn't feel like that, did she?

Nonetheless, Naruto and Naruto finally approached the over-eager pinkette, watching as Naruto climbed on the bed from the front- by Sakura's legs- and Naruto by the back, near her head. The original and his Clone took hold of their respective throbbing cocks, and began aiming them along the openings to Sakura's eager holes. Naruto had leaned forward as his tip rubbed against the kunoichi's slit, his hands tightly gripping Sakura's breasts, pressing into her erect nipples, the pinkette gladdened by the attention brought to her pillowy breasts. Naruto's cock had, meanwhile, been pressed to the kunoichi's lips, letting the musky odour fill her nostrils as the Shadow Clone gripped the railings of the hospital bed. It was a tight fit for the three, but the two blondes would enjoy themselves.

After a bit of breast groping and cock-slapping, the genin and his Shadow Clone had gotten to business, wasting little more time before their throbbing fuck rods slid into the kunoichi's tight-fitting holes. Naruto had the tighter fit, Sakura's narrow throat being more restrictive than the pinkette's wet, moulded pussy; still, that didn't stop the Shadow Clone from enjoying himself, considering who he was cloned from. The genin and his Shadow Clone gave Sakura everything she'd been craving, relentlessly slamming their throbbing, huge cocks inside her needy slit and throat, with the desire to fill both to the brim. Both of the blondes had been moaning louder than when they- Naruto- had been fucking Sakura's asshole, potentially due to a preference. Not that they were against piledriving the pinkette's big ass. Still, they did their best to be mindful of their volume, while Sakura was left with a juicy cock to gag her, silencing her desperate moans. Like before, her muffled moans seemed to be centred on being stuffed full of cum like the cumdumpster she was and how she was a personal cock sleeve, just for Naruto and his huge dick. Well, Naruto and his clones, that is. It was almost like Sakura was gradually drowning in pleasure, all of the intense fucking just leaving her a depraved cock-holster and cumdumpster for the blonde knucklehead. Naruto, for now, just found himself eager to feel the sense of euphoria when his Shadow Clone returned to him; the Clones he creates send their experiences back to their creator, meaning pleasure and pain all go to Naruto when his Clones disperse. This was bound to be something good.

Taking Sakura's words to heart, the original Naruto viciously slammed away inside Sakura's pussy, planning to hold nothing back as the pinkette's womb was vulnerable before him. As he penetrated it, he could feel her pussy clench and tighten up, something even he could feel within Sakura's throat. At that moment, Sakura orgasmed, eyes rolling back up in her head as she squirted against the real Naruto's fuck rod. Only, at that point, when Sakura seemed to recover from the powerful orgasm, her affectionate, loving personality as the blonde's cumdumpster shifted to an angry, yet confused, glare. With a muffled snarl, she bit into the cock of Naruto, forcing the pained clone to disperse in a puff of smoke, Naruto wincing as the experienced pain went to him. Before he could recover, Naruto witnessed Sakura wrapping her legs around him, supposedly to keep him in place, as the pinkette looked at him with a hateful stare: "What the fuck do you think you're doing, Naruto ?" Sakura's words brought confusion to the blonde until he remembered how he was able to do any of this in the first place. Her sudden personality change, hostility, and death glare; the genin was all but certain that this wasn't the Sakura he'd been training. Lord Seventh isn't the only one who has come from the past, which made him begin to wonder if anyone else was here.
