Springtime Shinobi 61 (Patreon)

With Tsunade interested in seeing what he could do and the only other treatment being to wait for her Chakra flow to return to normal, Seikun was given leeway to treat Sakura using his massage techniques. In the end, the essence of his technique was the same as the Mystical Palm and derivative Jutsu, but due to his control and the nature of his Chakra, there didn't appear to be any risk of disrupting the body's circulation or causing the patient to overheat, giving them symptoms similar to an extreme fever or potentially cooking them from the inside.

"So, that's how it is..." muttered Tsunade, observing Seikun with crossed arms and touching her chin with her right hand's index finger and thumb. She had returned to her true form in transit, but anyone who had seen the anime or read the manga knew this was also a transformation.

"Did you figure something out...?" asked Seikun, sitting beside a topless Sakura on her bed and supporting her left arm as he treated her Tenketsu, starting from the shoulder and working his way down.

Nodding, Tsunade explained, both for Seikun's and Sakura's benefits, "It's as you stated previously. Your techniques are effective due to your affinity with Water and Yin Release. But if someone were skilled enough and had the requisite control, they should be able to emulate them by substituting the tiger seal used in the Mystical Palm Jutsu with a dog or rat."

To demonstrate her point, Tsunade performed a modified ox seal before finishing with a dog seal, the hand seal most commonly associated with Water Release. When she was finished, however, the Chakra gathered in her right palm just caused it to become really wet, like she was sweating profusely.

"Well, that didn't work..." muttered Tsunade, trying again with the rat seal. This time, a noticeably cold air emitted from her palm, causing her to perk up and remark, "Oh? This one could be useful in Summer."

"It's no use," stated Sakura, wincing in pain as she explained, "I've tried a number of methods to emulate Seikun's ability...but I'm up to thirty-seven hand seals...and haven't been able to crack it..."

"Well, it's definitely possible," contended Tsunade, revealing, "Jiraiya even had some success emulating a handful of elemental release-style Kekkei Genkai in the past using Senjutsu as a binding agent. But he scrapped the idea due to how Chakra-intensive it was."

Trying again, this time using both dog and rat, with horse as a stabilizer, Tsunade was able to produce a thin layer of ice on her hand that became progressively colder. Unfortunately, the cold permeated into her hand, so even if it could be used to treat burns or something similar, it would likely lead to frostbite if used for an extended period.

Seeing how effortlessly Tsunade could string together various hand seals to test their effects, Seikun couldn't help feeling slightly envious. He could manipulate the Chakra forming his Shidai Seiun with covetable ease, but if he attempted imitating what Tsunade was doing, he was far more likely to freeze his hand to the bone. His control was excellent, but only Tsunade and Sakura had the capacity to use the bare minimum of Chakra required to perform and maintain a Jutsu.

"This is annoying..." said Tsunade, shaking her hand to dislodge the ice from it while staring at Seikun's. The notion that someone had a more effective version of the Mystical Palm Jutsu annoyed her considerably, so even if she had to spend years researching and developing it, much like she had her Creation Rebirth Jutsu, she and Sakura were both determined to crack the code...

Unfortunately for Sakura, who drew the shortest possible straw as a Taijutsu specialist against a skilled member of the Hyuga Clan, she was the only one among her, Hinata, Ino, and Tenten who failed to qualify for the Chunin Exam Finals. Tenten won her match against Kiba without much difficulty, as he 'couldn't go all out against a girl,' while Ino practically won the lottery by being matched against Shikamaru. He didn't even bother to step down from the catwalk overlooking the exam arena before raising his hand to forfeit the match.

The outcome that surprised Seikun the most was that Naruto was also eliminated after being pitted against Neji. Both were much stronger than their canon counterparts at the same age, but since there was no enmity between them and Naruto didn't have a reason to enter his baby rage hax state, the match was apparently one-sided. After that, things were pretty straightforward, with Sasuke, Lee, and Kiba winning their matches against a group of Genin in their late twenties and Shino handily defeating Choji in an exceedingly one-sided manner, leaving the latter and many others with an...understandable aversion to bugs...

'This pressure is insane...' thought Seikun, his throat tight and forehead beaded with sweat as he carefully inserted his hair-thin silver senbon into Tsunade's naked body, lying atop his massage table with a wet towel over her eyes. Hinata, Ino, and Sakura were assisting him, as usual, but he also had Shizune watching him like a hawk, her expression full of skepticism as she wasn't especially fond of traditional medicine. She was, however, very impressed with his ability to stay focused for the entire three hours it took to finish Tsunade's front side.

"Okay, time to roll over..." said Seikun, taking a moment to wipe his face, hands, and neck while Tsunade rose to a seated position, her magnificent breasts bouncing and swaying as she inspected herself and remarked, "I didn't give you enough credit before. I can already feel the effects of the procedure, and your ability to remain calm and professional, even in these circumstances, is pretty impressive..."

"I appreciate your praise, but we should continue the procedure..." stated Seikun, his voice sounding deeper than normal as his throat tightened and he defied the almost instinctual urge to gawk at Tsunade's breasts.

"Are you sure you don't need at least a short break...?" asked Tsunade, a playful smile adorning her face as she lowered her gaze to Seikun's pants and noted, "You seem pretty tense."

"Lady Tsunade..." muttered Shizune, her expression and tone chiding as she didn't feel it was appropriate for a woman Tsunade's age and status to make such comments to a young boy, especially in front of his fiancee and future wives.

"Hey, it took a lot of convincing to let you sit in and observe this medical procedure..." lied Tsunade, snorting as she contended. "Besides, there's no harm in a bit of playful teasing. The boy is already beyond fortunate to be able to see me naked. Let me have my fun."

Unable to contend with Tsunade's bullheadedness, Shizune exhaled an exasperated sigh before shifting her attention to Hinata, Ino, and Sakura. To her surprise, the trio didn't seem particularly concerned that Tsunade was effectively flirting with their fiance and boyfriend while naked. As for Seikun, he was sweating and looked a little pale, but his countenance was as calm and serene as the surface of a lake in mid-winter.

Causing Seikun's mask to crack a bit, Hinata calmly revealed, "We already permitted Seikun to sleep with anyone who undergoes this procedure and receives his massages. If Lady Tsunade is feeling frustrated, he should be able to relieve her without issue..."

Contrasting Shizune's slack-jawed stupefaction, Tsunade loudly snorted and remarked, "I remember this place offering such services in the past, but I didn't think the Hyuga Clan was shameless enough to try and revive their old business by forcing it on someone else..."

"I practiced these techniques of my own accord and decided to master them to benefit the village and people I care about..." stated Seikun, his expression and tone firm as he looked at Hinata and added, "Also...even if I have been given permission, I don't plan on carelessly engaging in those kinds of activities..."

Nodding, Hinata narrowed her eyes, smiled, and asserted, "And that's why we gave you our permission. We trust that you won't abuse it, but we also know how easy you are to exploit. If a woman as attractive and confident as Lady Tsunade were to pressure or confide in you regularly, you would eventually relent and endeavor to console her. You're too considerate not to."

"He does give that kind of vibe..." remarked Tsunade, recalling Seikun's words from a few days prior. She hadn't been looking for consolation, but he spoke to her as if he could tell she was enduring tremendous pain and sorrow. He reminded her of Jiraiya, but there was a distinct...certitude to his words. Like he didn't just empathize with her but understood what she was going through...

"Just don't go getting any crazy ideas like starting an actual relationship with him..." said Ino, sporting a look of concern. She was unaware that Tsunade was using a very advanced Transformation Jutsu to maintain her current appearance, but that didn't change the fact she was beautiful and beyond mature. When she pictured what guys really wanted in her mind, it was always a voluptuous beauty like Tsunade.

"Oh? At least one of you appears to have your head on straight..." mused Tsunade, smiling as she teasingly appended, "Don't worry, little girl. This beautiful Onee-san won't be stealing your boyfriend away. If I really need someone to scratch my itch, there are plenty of...proper men in the district nearby..."

Feeling offended, Ino crossed her arms and retorted, "You only say that because you haven't seen the monster Seikun keeps in his trousers. And when he gets riled up, he's more beast than man..."

"Saying things like that is unnecessary..." muttered Seikun, reaching up to caress his face and forehead, completely forgetting he had just spent the past three hours adjusting Tsunade's body to make inserting the senbon a little easier. As such, his hand had a faint but noticeably floral aroma, the result of her taking a protracted bath and cleanly shaving a certain part of her body in preparation for the procedure.

"You're pretty shameless..." remarked Tsunade, grinning when she saw the look of horrified realization on Seikun's face. Then, directing her gaze to his trousers, she caused Shizune to facepalm as she added, "Well, let's see it. And don't worry, I'm a seasoned medical specialist. I've given more physicals than you've taken shits."

Looking at Hinata, Ino, and Sakura, finding each of them staring at him as if they couldn't wait to see Tsunade stunned to silence, Seikun closed his eyes, sighed from his nose, and proved how much of a pushover he could be by unzipping his trousers and lowering both them and his boxers. Once this was finished, he stood upright with the most impassive look he could manage while Tsunade and Shizune, genuinely stunned, stared wide-eyed and slightly slack-jawed at his not-so-little brother.

Shifting her gaze to Sakura, in particular, Tsuande questioned, "Didn't you mention that you and Seikun were sexually active? How are you even able to walk around...?"

Though she blushed to the tips of her ears, Sakura appeared more proud than embarrassed as she puffed out her nonexistent chest and asserted, "It was very painful the first time, but after the procedure you're currently undergoing, it wasn't just my joints that became more flexible. I still can't take the-"

"Please spare me..." said Seikun, his face feeling like it was on fire as he pulled up his pants and added, "If you girls really want to talk about this kind of stuff, I'm going to go cool my head for about forty minutes. I can't complete the procedure in my current state..."

"And what happens if you can't...?" asked Tsunade.

Shaking his head, Seikun explained, "It's not strictly required to do all at once, but you may feel off and could experience difficulties molding your Chakra until the remaining pathways have been relaxed. For someone as skilled as Tsunade-sama, I doubt it will be an issue..."

"That tongue of yours may as well be coated in gold..." remarked Tsunade, compelling Seikun to avert his eyes as she turned her body sideways and sat on the edge of the massage bed with her legs slightly parted, causing the tips of his ears to burn like fire as she added, "But I'll admit...with the exception of a few Kumo Shinobi I treated in the past, yours is the biggest I've ever seen. It actually looks a little painful...for you, I mean..."

"I'll take care of it," said Hianta, grasping Seikun's hand with the intention of leading him to a nearby room to help calm him down. Before she could, however, Tsunade added, "Hold up...since I'm primarily responsible for its current state, I'll take care of it. It's been a few years since I've been able to scratch my itch sufficiently..."

Before Shizune could attempt to talk her out of it, Seikun surprised nearly everyone by meeting Tsunade's gaze and, very firmly, stating, "I refuse..." without a second's hesitation.
