A/N: Has Naruto met Karin? I'm not too sure and all the wiki says is she knows what his chakra makes her feel. I'm going to pretend that they haven't met in a clear and formal way and she just knows him by name.
Naruto was relaxing in his now clean apartment, having returned a while ago surprised at how spotless it looked, with only a not on his fridge;
Dear Naruto,
We know that you're going to make Karui part of the harem, so while you're away, we took the liberty of cleaning your place. Hinata's fine with just cleaning as her reward, but I expect you to pay me back for all the work I've done fixing what you call a home. Come by the sand village a week from now. We'll be alone.
Naruto chuckled as he looked back over the past half week and thought to Kurama,
"Thanks buddy." He didn't respond as Kurama was sleeping at the moment. However, his thoughts were disturbed when a bird entered his window, note attached to its claw. "Must be Sasuke!" Naruto proclaimed excitedly as he took the note and freed the hawk. He uncurled his note and read,
Naruto,
How's the village? I hope it's in good hands or you're dead. There's something I need you to do. One of my taka won't stop following me with her hopeless love for me. You won't find me but my last whereabouts is Amekagure. Use shadow clones to trap her since she can sense you. Tell Sakura I said hi.
It ended there. Naruto was confused why he needed help with a woman following him, but given his luck so far, he decided to save it till after his job was done. So he informed Kakashi about his mission before departing.
It took a couple days getting there by boat and getting through all of the necessary paperwork to enter the city, let alone a search warrant permitted by the Hokage himself accepted, but finally on the beginning of the third day, Naruto was ready.
"Shadow Clone Jutzu!" About 100 clones appeared surrounding him. "Alright, let's find this Taka woman!" They all shouted in determination as they swarmed the city. Some problems popped up as the search went on; angry locals who attacked when provoked, the city looking like a maze with its dreary environment looking the same all over, even a few clones being poofed due to someone attacking them or something accidentally injuring them, but after a couple of hours, he found the person who fit the description that he memorized back in Konoha; red hair, purple top and glasses. However, how he found her was not pretty. Karin looked really beaten up. Her glasses were broken, some of her hair was torn out, her clothes ripped and shoes missing, her face swollen and purple, she was a mess. In a panic, he dispelled his clones and picked up the battered Karin and went to find a medical ninja in the village. Unfortunately, not only were there no medical-nin, nobody bothered to help her. Even the clinic gave her back after only applying basic medicine and bandages. She was at least stable, but still far from healed. Running out of options, he found the nearest apartment he could check into and laid her down on futon. "Kurama, what do I do?!"
"Place your hands over her. I'll give her enough to wake up." Naruto did as he was instructed and the tailed beast let his chakra flow into Karin, waking her up barely. She grunted as she saw her savior.
"Are...you...?" She tried to ask but Naruto shushed her.
"Save your strength. You're beaten up pretty bad." Noticing how badly she was hurt, she slowly brought her arm up to her mouth. "What are you...?" He started to inquire but as she bit herself her wounds were disappearing. Her swollen face shrunk and returned to its normal color, her hair growing back, and visible pain alleviating. In no time, she was good as new, taking some of her bandages off.
"Thanks." She simply said, almost not acknowledging him at all.
"Umm, you're welcome?" He awkwardly said.
"It's not you, it's just that I need to find Sasuke-kun again. Those guys who beat me up seriously made me lose my tracks." She got up and walked to the nearest wall to find the door.
"Wait, Sasuke sent me to get you." She then stopped in her tracks, turned back to the boy and questioned,
"You know Sasuke? Who are you?"
"Naruto Uzumaki, his best friend." She lightly gasped.
"My last name is Uzumaki. Karin Uzumaki." She revealed.
"Wait, so does that mean we're cousins?" Naruto wondered.
"Probably. Wait, you said Sasuke asked you to fetch me?" She asked confused.
"Yeah. He said something about you annoying him and wanting me to stop your pursuit of love. Something like that." Hearing this, she dropped down to her knees and cried. "Wha-what's wrong?" He asked concerned.
"That Sasuke is such an idiot! He leads me on a wild goosechase through four of the great countries for months, leaves me in a constantly raining city, let's me get beat up, and sends someone several days away to help me! I don't want anything to do with him ever again and this time I mean it!" After that little rant, she stayed there for a few seconds before pouncing on Naruto crying. "Why doesn't he want me?! I'm beautiful, caring, kind, what am I doing wrong!?" As she cried here eyes out, Naruto felt very uncomfortable. He had no idea how to cheer her up or answer her questions. He had no response. All he could do was hug her. Within that instant, she directly recognized his chakra from before. It felt comforting and warm. She also recognized the scary aura in him but it didn't feel so malevolent now.
"I remember your chakra." She whispered.
"What?"
"I can sense other people's chakra, and how they feel like as if chakra had their own personality. I remember meeting a chakra that felt just like yours. Nice and warm, and yet something dangerous inside, though not as much as before."
"That'd be my tailed beast, Kurama. I'm a jinchuriki." Karin looked impressed hearing this.
"That's so cool!" She then smelled something for a few seconds and sniffed her armpit before turning away disgusted. "Eww, I reek! Trying to fend off those guys did not do wonders for my hygiene." She then turned to Naruto. "Hey, want to take a bath with me?" Naruto sighs, both from desensitization, and simple acceptance.
"Sure, why not." This perplexed Karin.
"Why did you accept so easily, and like that?"
"My whole week has been crazy, so even something like this feels like a nice break."
"O-okay." Karin stated, not wanting to know what he has been going through.
In short time, a bath was made and Karin was sitting alone, letting the bubbles hide all the bite scars she got. ("Why do I have to be covered with ugliness? What if he rejects me? I don't want to be alone.") A noise of a sliding door occurred.
"Excuse me." She turned her head to see Naruto, his whole body revealed except for his groin by a towel and his bandaged arm.
("He looks so hot.") She thought to herself having a minor nosebleed and a major blush. She rubbed it away just as he was getting into the bath with her, sitting behind her.
"So, why did you want me in the bath with you?" Naruto inquired.
"Just as thanks, that's all. It's not like I have feelings for you or anything." She explained.
"Let me guess, you're in love with me, right?" This caused Karin to squeal in surprise.
"How'd you know?!" She practically shouted.
"You just admitted it." He chuckled. Karin sunk everything up to her nose in the water to hide her embarrassment. "Also, I've been making myself a harem. Normally I'd be reluctant saying that, but given you loved Sasuke, a harem probably isn't the craziest thing you've heard of." He explained chuckling some more. Karin slightly smiled.
"No, it isn't." After a few seconds, she spoke up. "There's something I need to tell you." Naruto perked up as she swiped away most of the bubbles, revealing her bite scars. "My mother and I were considered weird, but useful for our unusual healing capabilities. My mother died from overexerting her ability. The village I lived in was attacked and I was tortured. Bitten all over even when they didn't need healing. Orochimaru and the others with him helped me recover when I was rescued so long as I went along with their experiments." Naruto looked sad.
"I'm sorry you went through all that."
"And I guess that's why I tend to fall in love with people who save me. I didn't fall in love with Orochimaru, but I fell in love with Sasuke, and now you."
"Aren't we still cousins?" Naruto asked.
"I'd like to think we're distant." She turned her head to kiss Naruto. Kurama's sixth tail glowed. While they were kissing, Naruto let his hands roam over her body, starting with her upper back which didn't have bites, and slowly moved to her bite heavy arms, her sides, her stomach, her legs, her feet, before finally going back to mid-torso to hug her. "Thank you... for loving me... I feel so... happy." She said between kisses. Naruto gasped into their kiss as she starting stroking his hardened dick. "Oh, do you have a thing for your cousin?"
"Come on, don't make it weird." Naruto whined. Karin smirked as she turned her body around and furthered her kiss into him while stroking up and down on his member. Naruto pulled from the kiss and sucked on her neck, making her gasp. She tightened her grip making Naruto wince in pain.
"Don't put your mouth on anywhere but my lips." She warned seductively. Naruto nodded so she loosened up her grip on his member and continued to stroke. Naruto leaned forward so that Karin was laying against the bathtub. She raised her legs and wrapped them around his torso, pressing their crotches together. "Ooh, now who's getting all touchy-feely?"
"I was looking for just a bath, but you tempted me too much." Naruto answered with a sexy growl. "Now you're going to pay." He started fingering her in Karin's special hole making his cousin gasp and moan in arousal. Their voices echoed in the bathroom as they continued pleasuring each other. Out of nowhere, Naruto put his hands under her butt cheeks and lifted Karin out of the water while getting out. "We don't want to get pruny staying in there too long. We can return to it to seriously clean up." Naruto placed her down on her hands and knees doggy style. He started playing with her pussy again. "You're very lewd, are you?" In pleased annoyance, Karin asked,
"What makes you say that?"
"The fact you aren't refusing, and you're clearly enjoying this."
"Despite that, I'm not lewd." She denied.
"We'll see about that." He stated before flipping Karin over onto her back and aimed his hard penis over her entrance.
"What are you waiting for?" Don't hold back." Karin challenged. Naruto nodded as he shoved himself into her, making her gasp in moan in eagerness, though this time, nothing was broken. He looked down at her. "I was raped before Orochimaru found me. I think that's part of why I disliked most people. It's only those that show me kindness and save me I love." She explained while breathing heavily. Naruto frowned from this information and declared,
"Karin, I won't ever mistreat you. You're now part of my harem, so I'll treat you the best I can do." Naruto decided to cheer themselves up by taking one of her feet and licked between the toes while having sex with her, forcing her to laugh uncontrollably happily.
"No, don't! Not the feet!" After he decided she had enough tickling, he pulled out so he could position Karin on his lap facing away from him, and continued having sex in front of a mirror.
"Look at us. Does this turn you on?" He asked seductively.
"We look so sexy." She commented.
"Yeah, we're such a lovely couple." He added as he began to push her up and down on his shaft. Karin contributed by using her legs to control how much weight to use. They both panted and groaned in happiness as the minutes went on by. "Karin, I'm nearing my limit. I'm going to go full force!" He then started thrusting into her pussy at full speed, catching the ex-taka off guard.
"W-wait!" She cried but he didn't listen. He kept going and going until he came into her, both screaming at the height of their climax. Naruto felt pretty good, until he was kicked in the face. He smacked into the wall behind him hurting his head.
"Oww! What did you do that for?!" He inquired.
"I wasn't on the pill, idiot! But you were too much into your sex frenzy! If I get pregnant, you're responsible!" Karin shrieked at him in anger.
"Oh, sorry." Naruto apologized remorsefully. But then he was tangled up with these dark golden chains. "Wha-what's happening?!" He looked to see them protruding from Karin's back.
"You came inside me without permission. Now you're getting punished." Naruto gulped.
5 minutes later, Naruto was pinned to the bedroom floor on his stomach. "Now then, let's get it on." Karin stated as she formed two more chains and whipped them across his back. He cried in pain. She whipped him again, and again he cried out but this time there was some liking to it. A third time, and his cries were sounding like he wanted more. Karin grinned as she gave him what he wanted by now rapidly lashing across his back and butt, never really hurting him but enough to leave impact marks. Each impact made Naruto gasp and moan in excitement.
When this started to grow boring to the ex-Taka, she turned him over onto his abused back and stared upon his hardened dick. She lowered herself over his crotch in fascination. "Just how can a man be so large? I've had the unfortune of one of many being stuck in me, but for some reason yours truly attracts me so." She took his member and put it in her mouth causing Naruto to groan more. ("It has a strange taste. I wonder what would happen if I bit it?") She softly bit into the penis, but this caused Naruto to jerk his hips forward, plunging his member deep into her throat. She bent her head back to cough and gag. One of her chains lashed against his face, leaving a thin line of blood. "Don't get ahead of yourself." She warned.
Karin then continued her work sucking him off, making him feel great.
"Oh man, that feels so good, Karin. My mind is going numb. I-I'm going to cuuum!" He shouted as he climaxed into her mouth, forcing her to once again back away as his essence spilt onto the floor.
"Too sudden. It's also a bit bitter to me. Maybe I'll like it better from the other mouth" Karin stated to herself as she mounted on his crotch. "Oh, and just so you're not too comfortable." She carefully stuck one of her chains up his anus, making Naruto shout in pain.
"Augh, too much! Too much stimulation!" Karin grinned. She aimed his penis towards her pussy and lowered herself onto it, gasping in enjoyment.
"Oh my god! I can't believe you feel so damn good!
"You're great too, Karin! Your insides feel so tight!"
"I never thought sex would feel this amazing! Somehow doing it with the one you love feels like heaven! I thought my body was ugly from all the scars, but you didn't mind them, and it makes me so happy! I love being seen as a beautiful woman by you! Despite the memories of that horrible day, your kindness just makes me want to have the good kind of sex with you multiple times!"
"Use me as you want, Karin! Let it all out!" Naruto encouraged. Karin took the opportunity to kiss Naruto on the lips. They did this for about a full minute before the building pressure inside the kunoichi broke and she came on him. However sensing he was just about to cum as well, she used her chains to pull herself off just before he burst, his semen spraying the floor again. Once she recovered from her orgasm, she commented,
"Nice try, but I'm not getting pregnant from two shots inside. At least not yet. Now, let's try this again." She licked and sucked his dick to clean it before resuming sex with him. But this time she used her chains to suspend themselves off the floor, rocking the both of them back and forth like a bucking horse to make it feel even better. "Oh, your dick is so strong! You feel so great! You're making my insides messed up! Having your dick inside me feels fantastic! You feel like you're growing hotter and bigger! You better not blow into me!"
"You feel so amazing! It feels so good to fuck your pussy!" He agreed with.
"Naruto! Naruto! I'm going to come agaiiiiiin!" She screamed as her pussy squeezed down on the dick she was having sex with, but once again pulled away before Naruto could climax into her. However, due to reaching climax three times by now, her adamantine chains finally dissipated and they fell to the floor with heavy thunks. They panted as they let their highs wear down in short time.
"Karin?"
"Yeah?"
"Want to come with me back to the hidden leaf? You'll be part of my harem."
"I'd love to."
A/N: I may have tweaked Karin's story a little bit. I fully acknowledge that rape is a super serious thing, and that what I wrote is not fully realistic since I don't know anybody that's raped or how to exactly research people who experienced and recovered from it. I was making it that Karin is at the very late stages of recovery to be as good as she is in Shippuden. If any of you seriously think I should remake the chapter so it's handled better I wouldn't mind a link or two. And as for why I added Karin being a rape victim? Well, for one it should be possible in the cutthroat ninja world before peace overcame the hate. And it felt like that if Naruto gave her acceptance and love inspite of the fact, she could easily fall in love with Naruto just as she did Sasuke. Different reasons, but in this story he did save her so it seems like she has a sense of rescue romance mentality.
I hope I did an okay job writing this chapter and didn't upset anybody. And to those that I may have, I sincerely apologize.
