I, Your Father, Carry a Big Stick

"You gonna be okay...?"

With her ass still sticking in the air and half-rolled-back eyes, Kaia replied with a curt, characteristically raspy, "I'm...great..." before rolling onto her side so that she could stare at Wu with a very 'devoted' look on her face.

Though Kaia was the shortest and leanest among the girls Wu associated with, she wasn't entirely without charm. Her body was simply...compact, so while she was lying on her side and gazing at him, her muscles visibly contracting whenever she exhaled, Wu couldn't help smiling as he softly mused, "Who gave you permission to be so cute...?"

Contrasting her heritage as a member of the Inuzuka Clan, Kaia exhaled a giggling, "Nyaaah, don't look~" as she curled up in embarrassment with a happy smile on her face. Fortunately, she still had her shirt on, so she was able to conceal her 'shame' before rising to a seated position, adopting a nervous expression and asking, "This wasn't...just a one-time thing, right? I mean, I don't mind-"

Before Kaia could finish speaking, Wu smacked his naked thigh, saying, "Come and take a seat, puppycat."

Though she immediately moved to comply, Kaia hesitated when Wu's not-so-little brother abruptly stirred, nearly reaching her face as she crawled on her hands and knees. It was 'a lot' more intimidating close-up, but she only hesitated for a second or two before crawling atop Wu's lap with her feet in the nook between his thighs and hips, holding his right shoulder as she used her left hand to try and guide his penis to its destination.

Interrupting the girl's efforts, Wu stated, "This is my answer. You're not my pet, Kaia. So long as you continue to work hard to achieve your dream, I'll fuck you as often as 'you' desire..."

Punctuating his words, Wu helped Kaia angle her hips properly and let gravity take care of the rest. A loud, hoarse moan escaped her throat as she slid down nearly half the length of his cock, following her grasping his shoulder and clinging to him for support. At the same time, Wu supported her sides, a green light emitting from his palms to combat the cramping of her lateral and abdominal muscles.

Since she couldn't go any lower, even if she wanted to, Kaia just remained in her squatting position, clinging to Wu for nearly two full minutes before admitting, "I love Wu-nii..." in an audibly impassioned tone. Then, as if to prove her affection, she bit down on his shoulder but was unable to break through his skin despite her sharper-than-usual teeth.

Before his loyal puppycat could begin whining, Wu willfully decreased the durability of his flesh, allowing her to sink her teeth into him while he gave her a few light pats on the back. The Inuzuka Clan didn't have a tradition of marriage. Instead, they would 'mark' the person they intended to mate with for the rest of their lives. Wu wasn't too fond of the idea of someone leaving a permanant bite mark on his shoulder, but it was marginally more acceptable if he considered it a battle scar...

After clamping down on Wu's shoulder for several minutes, Kaia unlocked her jaw, leaned back a little, and stared at him with a toothy, unabashedly blood-stained smile. Her usual devoted look now gave the impression she would readily die for him, so Wu returned a smile of his own as he said, "It looks like we're stuck with each other for the rest of our lives..."

Shuddering at the thought, a tremendous volume of love juices flowed from where Wu and Kaia were connected, her body sinking noticeably as if her insides did their best to accommodate his intrusion. When he further punctuated his words with a kiss, Kaia could no longer control her actions, peppering Wu's face with kisses as she began to buck and shake her hips with reckless abandon. She 'wanted' Wu to feel good. She 'needed' him to pamper and praise her...

As his original intent was to stop by and ask if Kaia wanted to participate in the month-long training camp, prompted by the other girls to at least ask, Wu didn't mind the puppy-like girl clinging to him the entire way back to the Senju Clan Compound. Her mother, Nao, just told him to bring Kaia back if she ever had pups, so it was safe to say the bushy-haired brunette would be a semi-permanent resident in the estate from now on.

Upon reaching the estate, Wu found Tsunade in the middle of lecturing the girls using an anatomical model she had 'borrowed' from the Konoha Hospital. His arrival immediately derailed her lecture, so the busty blonde crossed her arms and gave him a sharp look as she asked, "Another one?" in a flat tone, willfully disregarding the fact Wu had already told her about Kaia.

Before Wu could respond, Ino excitedly exclaimed, "Kaia-chan~!" before running over to pick up and cuddle the slightly shorter Inzukua. Ino was one of the few girls that found Kaia's behavior endearing, and she wasn't shy about demonstrating her fondness for the puppy-like girl.

Equally fond of Ino, Kaia developed a toothy grin as she nuzzled against the taller blonde and readily revealed, "Aniki and I finally became mates, Ino-chi~!"

Instead of being surprised by the revelation, Ino squeezed Kaia even tighter as she issued a girly, "Kyaaaaa~! Congratulations, Kaia-chan~! We're practically family now!"

As she had always viewed Ino and the rest as members of Wu's 'pack,' Kaia just gave an affirming nod before surprising the bubbly blonde with an affectionate mouth lick. A stunned look briefly marred Ino's face, but she quickly regained her smile, narrowed her eyes, and teased, "Naughty girl, Kaia-chan..."

"Eh...?"

As she didn't understand how she had been naughty, Kaia was about to ask before Ino surprised 'her' with a kiss. Her eyes widened to their limits, but she didn't attempt to break free, even when Ino's tongue invaded her mouth.

Interrupting the impromptu lesbian play, Tsunade whacked Ino's backside with her switch-like pointer, exclaiming, "Stop making a fool of yourself in broad daylight!" before turning to Wu and asking, "Let me guess, you want me to train this one as well?"

Nodding his head, Wu revealed, "Her job includes treating sick and injured dogs, so I figure it wouldn't hurt if she learned some proper medical skills. Ninken aren't exactly human, but I'm sure someone as capable as you can guide her properly."

Snorting through her nose, Tsunade looked down at Kaia, towering over the naturally petite girl by a full head. Kaia's legs trembled due to the aura exuding from the much stronger woman's body, but she managed to stay her ground, a progressively fierce look developing across her face as she began to growl.

Though she snorted a second time, Tsunade remarked, "At least she has guts..." with a faint smile. Then, with significantly more disdain, she looked down at Ino, still rubbing her ass, and stated, "Stop being overdramatic. I barely even hit you."

Furrowing her brows, Ino felt compelled to retort but swallowed her words the moment she looked up and met Tsunade's gaze. The latter wasn't known as a Legendary Kunoichi for nothing. Compared side-by-side, Tsunade's Chakra Capacity was like a vast lake, while Ino's could barely be called a pond. She normally wouldn't cower before anyone, but in the face of Tsunade's overwhelming presence, Ino immediately became meek.

Returning her gaze to Wu, Tsunade's expression and tone was firm as she said, "The girls are mine in the afternoon. If you want to train them in the mornings, show some restraint during the evenings. I know it feels good, but you'll become useless if you get in the habit of spending all your free time fucking."

Finished with Wu, Tsunade turned to the group of girls and added, "That goes doubly for you girls. Wu is already a little monster, so he has a bit of leeway to act without inhibition. If you let yourselves get caught up in his pace and submit to indulgence, you're going to become lazy and stupid. I doubt Wu will let things get that far, but it's 'your' responsibility to restrain both him and yourselves."

Though Hinata, Sakura, Tenten, and even Hanabi all nodded their heads in affirmation, pouts appeared on the faces of Ino and Kaia. They didn't see anything wrong with having sex if Wu was willing, but they also didn't try to argue. Four years of training alongside and beneath Wu had given them a thorough understanding of his personality and nature. If they did submit themselves to pleasure and stopped trying to improve, he would be 'very' disappointed in them.

Adding significantly more weight to Tsunade's words, Wu crossed his arms and firmly appended, "If I notice my actions are hampering your growth, I'll simply stop having sex altogether. I didn't fall in love with everyone here just because I coveted your bodies. It's because you're strong, capable women who possess a sincere desire to improve. I refuse to become the cause of your decline..."

If they had 'understanding' expressions in response to Tsunade's words, all of the girls became 'serious' when they heard Wu's. His words implied that he wouldn't have sex with 'any' of them if even one of them slacked off or became a hindrance. None of them wanted to be the reason for the entire group going thirsty, so the girls exchanged stares with one another, a silent pact forming between them while Tsunade nodded in approval...

As it had been a week since he last violated the sanctity of Tsunade's chambers, Wu elected to reward the busty blonde 'graciously' for her firm stance against the other girls. She was technically supplanting the role he had prepared for Tenten, but as the latter willfully capitulated to the much older Kunoichi, Tsunade was now the de facto 'steward' of Wu's harem.

Biting her wrist in a desperate bid not to cry out, Tsunade's body rippled and heaved with each of Wu's intense and passionate movements. One of the reasons she had warned the other girls is because she was already on the verge of yielding to Wu's 'vigorous' ministrations. She had attempted, numerous times, to keep track of how many times he made her orgasm in a single session. Unfortunately, she would consistently lose count as the ever-mounting pleasure caused her to fade in and out of consciousness...

Spurred by Tsunade's attempt to hold in her voice, Wu surprised her by flipping her over and pinning her beneath him with her legs raised, aided by her natural flexibility. She was surprisingly weak to kisses, so he kept stealing her lips despite her attempts to avoid the intimate exchange. She even tried to bite him, but that merely excited Wu further as he continued chasing her lips until she eventually just gave up.

With the last bastion of her lips breached, Tsunade abruptly became a lot more 'honest.' The rational part of her mind told her she shouldn't yield to Wu's transparent attempts to dominate her body, but an increasingly loud voice 'demanded' she attains even greater pleasure. She had such a large hole in her heart that no amount of drugs or alcohol had ever been able to fill it. She doubted Wu would be the one to mend her broken heart, but his unfettered passion was her best 'medicine' against the symptoms...

Not wanting to submit completely, Tsunade broke free from Wu's pinning hold and reversed their positions in a flash. She felt that Wu really would dominate her if she continued permitting him to do as she pleased, so, for the first time since their wedding night, Tsunade reclaimed the initiative...

(A/N: Tsunade's words and actions may seem a little hypocritical, but she is already powerful and has accumulated innumerable achievements. She has the right to enjoy her 'retirement' xD...)
