"Man, you've got the best mouth, like a little kitten playing with a toy."
"Yeah, sure, see you next time." Koneko waved 8 members of her harem out of the room, with the last one needing to comment before he left. She had already had sex with her pets before she invited her harem over, and even cleaned herself out just for them. Then she satisfied her entire harem, until none of them could get hard anymore at the very least. It was overall a very enjoyable experience for her.
Now she needed another bath to clean herself again.
She didn't care if they came inside of her, but she found the act of washing herself out to be time consuming. There was no benefit to her allowing them to cum inside, other than the fact that she liked the feeling of when it dribbled out of her when she took too many loads for her body to contain normally.
"Shirone."
"Oh, hello Kuroka." Koneko turned around and saw her sister sitting on her now open window, she had opened the window to allow the room to freshen up a little. When she had been in a party in the Underworld, she had sensed her sister's familiar and had sensed her sister herself. She had been too busy going under the table and sucking off a table of rich high class devils. She had surprised them, and none of the men at the table realized that she took turns giving each of them blow jobs.
She had spent nearly a month in the Underworld at that point, and she was too used to sex to just go a month without it. She needed something to at least get her cravings, and she didn't care too much since none of them looked at who had snuck underneath the table to see who she had been. She could be very stealthy when she wanted to be.
"You didn't come see me in the Underworld, when I took the effort to get close to you, just to see how my darling sister was doing."
Kuroka shared some similarities to Koneko, in that Kuroka was on the shorter side with cat-like eyes and other cat-like features. They had similar eyes and faces, but Kuroka was a complete bombshell with her body, while Koneko was had an athletic and lean body.
"Can you go away, I need to take a bath. Things always get messy when I invite my harem over, and I don't have the time or desire to deal with you." Koneko didn't care too much about her past with her sister anymore. There were way too many important things on her mind, and things in her life that just flat out took a higher priority to this woman. Now that she was aware that Kuroka had not gone mad via the influence of Senjutsu thanks to Naruto, she didn't even had a reason to fear her sister.
Kuroka was just Kuroka to her now.
Her black haired sister was now amused by what she said.
"... Shirone, you should be risking getting pregnant with your body... it could be dangerous to you."
Koneko scoffed.
"I've already given birth several times now, and despite what you seem to think, I'm a grown woman now. Girls younger and smaller than me have given birth many times in the past, and I'm friends with an expert healer, AND a great potion maker... now you can join me in the bath if you want to catch up, or you can just go away because I don't have the time for you right now." Koneko waved a hand dismissing Kuroka. She wanted to get washed up, since she needed to make herself presentable if she was going to be showing herself to whatever monster's Naruto had spent his time cooking up.
Kuroka's jaw just dropped slightly, unsure of this confidence that her sister showed. Her little sister was so confident and sure of herself, that even though she was dozens of times more powerful than the girl, she still had no problem mouthing off.
"I could destroy-"
"Just because you're stronger than me, doesn't mean I respect you or have to show you respect. The way I see it, you're my no-good sister that abandoned me... might have been for my safety, but that doesn't excuse the fact you never sent me a letter explaining what happened. I spent years of my life being afraid of my heritage because of you." Koneko walked right passed Kuroka and went into the bathroom.
Kuroka followed after her, but she wasn't able to say anything as she stripped her clothes off. She saw her sister enter the shower as the bath started to heat up, and rinse the semen off of her body. She licked it off of places that her tongue could reach, but everywhere else got rinsed.
'My sister... she's turned into a slut...' Kuroka had that one thought.
She saw semen pooling on the marble floor underneath Koneko as she sat down, coming right out of her still slightly gaping snatch.
"It's kind of a waste of good semen, but I bet you know the feeling. When a human cums inside, it's hard to really tell the feeling. I can only feel it when it's coming back out, but as much as I like the feeling, those guys worked really hard to put that in me." Koneko glanced over at Kuroka. She remembered how seductive her sister tended to be when they were younger, so she was sure that her sister was super experienced.
Kuroka just stared at her sister's body.
"You've... given birth?"
"Yes, to several Tentacle plants, Cat Slimes, some minor monsters as well. Sometimes I like to let the Cat slimes get me pregnant again just for fun, and I make sure to take good care of my tentacle plants, because sometimes I just get the craving to get some tentacle in there." Koneko had a small, almost serene, smile on her face as she spoke of her perversions to her sister.
"... But... that doesn't restore our species."
"I don't care about restoring our species, the Nekoshou can go extinct for all I care about. Lets be honest, you, me, and our mother were the last of our species... then she died, you killed a high class guy, and I was going to be executed for your crimes... both of us are Devil hybrids now... the pure-blood Nekoshou species is gone now... maybe forever." Koneko didn't care about her species at all. She wasn't a full blooded version of her species anymore, and neither was her sister.
Kuroka was crazy if she thought that at this point she could restore their species, but that was a fool's dream. Koneko put her hands above her stomach, and she smiled as she thought of the way better uses that she could use her womb for. The monsters that she could birth with it, instead of just the simple stuff like another member of her own species.
Her own species had similar growth rates to humans.
She didn't want to wait 9 months to give birth to something that might not be a boy, and she would have to wait until that boy was old enough to get hard before she could let him fuck her. That was IF he was a boy, and those 9 months she wouldn't be able to get pregnant with anything else.
"... So... you've... you've changed a lot." Kuroka was just still in shock from all of this.
She had watched her sister in the middle of that lustful gangbang where she fucked many dudes, she was pretty sure that she saw Koneko taking all 8 of them at the same time. 2 of them in her mouth, 1 in each hand, 2 in her pussy and 1 in her ass, with her feet reaching back to give another guy a footjob.
"I've changed for the better, I can have all the sex I want, whenever I want. I'm not the repressed little kitten I was who hated perverts. If you want, I can call my harem boys back, and we can bang them together... I'm sure one of them could knock you up, you can restore our species by yourself if you want." Koneko knew those boys would just die to have the chance to bang her and her hottie sister together.
"Uuuuuh... what?"
"Oh, sorry, I guess you've got your own harem. So, how many babies had you had so far?" Koneko knew that her sister was a pervert, so she had no doubt that her blood sister had the same inner pervert as she had.
Kuroka was very uncomfortable.
"I... what... I don't have a harem... I'm still looking for a strong mate, I want my babies to have strong genes... I can't just accept any man-"
"Any man? I don't accept just any man, I will only accept a man who can make me cum at least 4 or 5 times during sex... but I can let it slide with 2 or 3 if the orgasms they give me are really good." Koneko would gladly kick a person out of her harem if they started to underperform their duties. She was just fine allowing them to go out and do whatever they wanted with whatever other girls they wanted, she didn't care about them the way they cared about her after all.
They were just humans who wouldn't share even a fraction of her lifespan, but they would be fun to spent time together with while they did last. If they found a girl who made them happy, then she would be happy to see them go.
"What happened to you?" Kuroka was just worried at this point.
"I saw my own perverted orgasm face, and I refused to accept it so I wanted to prove that sex couldn't make me make that face or feel those feelings... and I was wrong. So, how many guys HAVE you had sex with?" Koneko had to ask, because her sister was sounding a bit like a virgin to her. "With how seductive you are, surely you have some experience?" Koneko sent her sister a judgemental look for the way that she started to blush upon being called out.
She stood up and walked towards Kuroka, while her sister was sitting down and rinsing herself off. Kuroka noticed Koneko approach her, and she could hear the surprised tone.
She blushed a deep red when she realized that her sister was far more experienced than her, and she knew it.
"Heh... I can see it all over your face, but whatever. Tell you what Kuroka, if you want, I can let you finish cleaning me out... maybe then you can claim to have some experience." Koneko lifted her leg and balanced it against the wall, bringing her pussy close to Kuroka's face as she loomed over the sitting girl. "Of course, you might just be able to put that cat tongue to good use, I like it rough."
"Shirone!?"
"It's Koneko, now if you will excuse me. I've got a lot of stuff planned for the day, so you can either eat me out, or stop wasting my time. If you want to be part of my life, you're going to have to repay me for the years that I spent living in fear thanks to you." Koneko pulled her leg back and started to walk out of the shower. She looked back at the stunned Kuroka, who hadn't been expecting Koneko to stand up to her in such a way.
She just sat with the shower running on her head, unable to come up with a response to what her younger sister had just laid out for her.
-With Naruto Later-
"Good you're here Koneko, I'll have a monster ready for you to test our tomorrow. Saves me the trouble of going and finding you. You fine with getting fucked by a horse-styled monster?"
Koneko had an exciting day planned for her tomorrow.
What she didn't know was that Kuroka was still in her bathroom, just sitting underneath the shower, shocked about what her sister had grown into.
The neko sisters both got great and horrible news.
Depending on who you asked.
