I, Your Father, Carry a Big Stick

Similar to the actual Kushina, Kushinada kept having sex with Wu until they 'had' to stop and take a bath. They fucked there as well, but not before Kushinada ate a peach that restored her right arm and revitalized her cells to the point she appeared to be in the same age group as Wu.

Understanding it would take years, potentially even decades, before they possessed the kind of power that would allow them to restore her world, Kushinada decided that she would become Naruto's actual big sister. The two of them shared functionally identical genes and Chakra signatures, so she intended to play the part of his twin, helping him befriend Kurama and teaching him some of the techniques that had made her the 'strongest' in her timeline.

Fortunately for Wu, Kushinada was more than satisfied with his cock. His was already the biggest she had ever taken, but his ability to augment his size even further was like a gift from heaven. She was a little disappointed when her breasts practically deflated to modest B-cups upon consuming the peach, but she was far more excited by the prospect of Wu 'breaking in' her newly rejuvenated body...

While his clones took care of preparing lunch and a few other tasks, Wu sat in a traditional ofuro-style tub with Kushinada still firmly planted on his cock, sitting with her back against him as she absentmindedly fondled her left breast and rubbed her clit.

Since he was pretty confident she wouldn't care at this point, Wu revealed his relationship with Kushina by casually remarking, "You and your mother have a lot in common. She also refused to separate from me the first time we fucked..."

Stopping the motion of her hands and fingers, Kushinada asked, "You're in a relationship with Naruto's mom...?"

Nodding his head, Wu revealed, "I've been a friend and a surrogate father to Naruto for most of his life. Kushina found herself in a dire situation after being reanimated by Orochimaru, so I did what I could to help out. A few months ago, the two of us crossed a line we probably shouldn't have, and the rest is history..."

Falling silent, Kushinada lowered her gaze and stared down at where she and Wu were presently connected, a deeply reflective look on her face. At least, Wu 'thought' she was thinking deeply. Instead, after nearly a minute of silence, she adopted a mischievous smile and inquired, "Should I start calling you Papa...?"

Adopting a smile of his own, Wu replied, "That would have made me harder than a diamond a few months ago. Now that I'm an actual father, I'd prefer it if you just called me Wu..."

After giggling in amusement, Kushinada began pleasuring herself again as she casually inquired, "Does Naruto know about your relationship...?"

Shaking his head, Wu admitted, "Not yet. Kushina asked me to let her be the one to break the news, so Naruto believes we're simply training and researching Fuinjutsu. There's some truth to that, but she's also been living in my room for the past six weeks, milking me at every opportunity. I honestly feel a little bad about it, as he's pretty much the only one who 'doesn't' know about our relationship. Even his wife, Karin, figured it out several months ago..."

Though she furrowed her brows slightly, Kushinada didn't attempt to chastize Wu for keeping things a secret. She also didn't think it was her place to expose them, so she eventually replied, "I'll keep it a secret as well. However, you really should tell him at some point. If you delay it for too long, he might come to hate you..."

Catching Kushinada a little off guard, Wu asked, "Have you ever hated anyone? While I can't imagine Naruto being 'pleased' to learn I've been banging his mom, I also can't imagine him hating me. I've seen him kill people in the past, but those were monsters undeserving of redemption..."

As someone who believed the cycle of hatred could only be broken when people were willing to forgive, Kushinada exhaled a tired sigh in response to Wu's words. If Naruto were anything like herself, he would probably be 'very' upset. He might even lash out and try to attack Wu. However, once he calmed down, he would invariably attempt to view the situation from a different perspective. Once he 'understood' why everyone had kept things a secret, he wouldn't have the heart to remain angry. It just wasn't in their nature...

Taking advantage of Kushinada's silence, Wu reached his hand between her thighs, taking over for her as he softly assured, "Don't let it bother you too much. Karin will give birth to Naruto's first child within the next couple of months. Once he has become a father and things have calmed down a bit, I'll tell him myself..."

"Eh...?"

Though she had heard Wu mention Karin a few times, even referring to her as Naruto's wife, Kushinada never would have guessed that the young couple was already expecting. She was nineteen when she gave birth to her son, so she was surprised to learn her counterpart had 'beaten' her by around four years. Of course, had she not been 'forbidden' from getting pregnant earlier, their situations may have been reversed...

Shaking such thoughts from her mind, Kushinada suppressed the sudden urge to have Wu impregnate her. She originally planned to have around a dozen children to help kickstart the revival of the Uzumaki Clan, but the loss of her first two currently weighed heavily on her heart. There was a 'very' high possibility that she would want additional children in the future, but it was much too soon to consider such things. Even if her cervix was practically kissing Wu's cock, hungry for his semen...

As her insides tensed instinctively, a wry smile adorned Kushinada's face as she suggested, "We should probably get out soon...if we stay like this much longer, I'm not going to be able to hold myself back..."

With a pretend incredulous look on his face, Wu questioned, "You milking my cock for four and a half hours is holding yourself back? You really are your mother's daughter..."

Snorting through her nose, Kushinada grabbed the sides of the tub and raised her body as if she was about to extricate herself from Wu's dick. As his glans scraped her insides, however, her actions became markedly less resolute, ultimately culminating in her stopping just as the head of his dick was about to slip out of her.

Seeing Kushinada freeze in place, a mischievous grin developed across Wu's face as he grabbed her hips and forced her to sit back down. A loud moan was forced from her throat, followed by her 'glaring' up at him with a pouty expression on her face. In response, Wu hooked his hands under her knees, rising to his feet as he playfully remarked, "You're not the only one struggling to hold themselves back..." Then, as she opened her mouth to speak, he invaded her lips with his tongue, silencing whatever she was about to say...

As Wu was only ever late for a single reason, Tsunade narrowed her eyes at him, remarking, "You seem to be making the most of this situation..."

Receiving the squirming infant that already had her arms stretched out to him, Wu's smile was as genuine as it had ever been as he mused, "That's the best way to live..."

Rolling her eyes, Tsunade turned away, intending to go lie down and rest before Wu stopped her, adding, "I'm thinking of having everyone relocate to Taki. With enemies capable of reducing Konoha to a crater teleporting about, the Senju Clan Compound is no longer safe."

As she had already been having similar thoughts, Tsunade didn't hesitate to reply, "I'm not against it, but we can't just leave Konoha unprotected. It also wouldn't be healthy for Momo to grow up without children her age to interact with. You should know, mister monkey boy."

Though he could see where Tsunade was coming from, Wu argued, "She is a lot stronger than other children. We need to teach her how to control herself, or else she may end up killing someone after they make fun of her for being 'different.' You know how insensitive young children can be..."

Understanding there was a 'considerable' amount of truth contained in Wu's words, Tsunade nodded her head, replying, "You're right. I have to use Healing Palm every time I breastfeed her, and my body is a hell of a lot more durable than some brat's..."

Crossing her arms in a manner that emphasized her breasts, Tsunade added, "But that doesn't change the fact she 'needs' children her age to interact with. If she grows up watching you philander about, she might end up developing some dangerous proclivities. I honestly don't care who you fuck at this point, but if you lay a hand on Momo..."

Narrowing his fiery eyes, Wu asserted, "You're toeing a dangerous line, Tsunade. Even if you're covering your bases, there are some things that shouldn't be said...just what kind of man do you take me for?"

Though she felt somewhat apologetic, Tsunade's expression remained firm. She knew the effect Wu had on women, and it wasn't uncommon for Noble Clans to try and keep their bloodlines 'pure.' There was also the possibility of Momo feeling 'ostracized' if she grew up watching virtually every other woman throwing themselves at Wu but was prohibited from doing so herself.

With Tsunade just staring at him in silence, Wu forced himself to calm down before stating, "We'll need to supervise them closely, but she can play with Naruto's and Karin's son. I could also impregnate Kagero, Mei, Koyuki, and a few of the older girls. If her siblings inherit the same traits, they should be able to play together just fine..."

Since she had already 'opened the floodgates' by being the first to get pregnant, Tsunade didn't attempt to dissuade Wu from impregnating other women. She still thought it was too early for girls like Sakura, Hinata, Ino, Kaia, and Tenten, but there were plenty of other candidates. If none were willing, she could even take matters into her own hands...

Nodding her head in approval, Tsunade regained her smile as she said, "That should work. However, I'm against everyone migrating to Taki all at once. Most of the younger girls are still part of active teams, and it would cause problems if you were to 'disappear' with the delegation from Kumo, my Grandfather, or the Kazekage's children. Taki wouldn't be very secure if every major nation learns you're keeping us there..."

As Tsunade made a very good point, one he had already considered the previous night, Wu gave an approving nod and said, "Then, at least for the time being, I'll have you relocate with Momo. Shizune will accompany you, and I'll have Kushina and Fu to keep you safe."

Though she suspected she had just waltzed into Wu's trap, Tsunade rolled her eyes and replied, "Sounds good..." before turning away and yawning, adding, "I'm going to take a nap. Wake me up in a few hours, and then we can fly or transport over. Space-Time Jutsus always make my stomach turn..."

Nodding his head, Wu asked, "Want me to make a clone and have him give you a massage while I stroll around with Momo...?"

As tempting as the offer was, Tsunade shook her head and said, "Not today. I'm still feeling a little spacey after yesterday's revelations, so I plan to mull things over for a bit. Ask me again later this evening, and I'll probably say yes."

Having said what she intended to say, Tsunade waved her hand without turning to look back at Wu and Momo. The latter's appetite was extreme, so her breasts and shoulders were incredibly sore after Momo practically sucked her dry. She needed time to rest and recuperate, so even though she was worried about her daughter imprinting a little 'too much' on Wu, Tsunade trusted that he wouldn't let things get too out of hand...
