First Fan Fiction.

Nanashi is Yusuke's cousin come to live him and his mother after her parents pass away. Takes place two weeks after Dark Tournament. Little does she know, she has caught the eye of a demon. HieiXOC.

Nanashi was tired after a long day at school. She, Kuwabara, Kurama, and Yusuke had missed so much class while at the Dark Tournament; equaling up to an impressive amount of homework for each. Nanashi half dragged herself up to the small apartment she shared with lazy cousin and rarely seen aunt. After kicking off her shoes, and dropping her bag carelessly by the door, Nanashi sighed. On the walk home, she, as usual was remembering back to a moment she spent training for the Dark Tournament; even though in the end the Mysterious Masked Fighter took her spot on the team:

Nanashi and Kuwabara were no where near ready for the Dark Tournament coming up. Once Kawimba realized that Nanashi also possessed spiritual abilities, an engergy battle axe, it was decided she needed to join the team. That's where the training came in. Kawimba determined both she and Kuwabara needed trained for the DT; which was to be done by none other than Hiei and Kurama. At first, the two trained together, but Nanashi was slowing Kuwabara's training down, so the training was seperated. One day with Hiei, and the next with Kurama. Training with Kurama was difficult, but with Hiei, it was next to impossible torture.
While training with Hiei, the day was filled mostly with terror, running, and fighting all over the woods. Nanashi would always lose. No matter what tactics she used or how hard she fought, Hiei would always win. He would pin her down or hold his sword to her neck and tell her she was "dead". She "died" dozens of times in her training. It just was not fair after a while and she desperately wanted to quit. Finally one training day, Nanashi made a decision.
Hiei and Nanashi had been training for hours. Nanashi had "died" four times. As she was about to "die" for the fifth time, so she just gave up fighting, leaned against a tree and closed her eyes. Instead of feeling the usual sword to the throat and hearing "dead", Nanashi felt a crippling, crushing pain in her right wrist. She cried out and opened her eyes and saw Hiei had her tightly by the wrist and was squeezing.
"Please...," she begged. "I'm dead again. Please let go."
"You're wrong," Hiei replied. "I haven't killed you yet. You're alive. Fight."
Nanashi refused to let the tears flow, even as the pain was so bad she dropped to her knees.
"Give up and you deserve to die a real death," Hiei told her. "Haven't you another pathetic trick up your sleeve. A faint, attempt to hide, something else useless."
She made no response and tried to stop the whimpers that came to her throat. She just wanted free.
Hiei was still staring down at her with red eyes blazing. "You're giving up that easily? Are you sure you're related to the detective?"
A twist in pain as Hiei adjusted his grip and squeezed harder on her wrist. She felt as if it was about to break. Desperately she thought, 'what can I do? What can I do? Im on my knees in front of him. There has to be something I can do.' She thought and thought amidst the pain. Finally she came up with a trick he would never see coming. Thankfully with his head wrap on, he could not read her mind.
Nanashi wretched her right wrist, which did not yield. Hiei hn-ed, which gave her the opening she needed. Nanashi half stood, reached up, grabbed his face with her left hand and kissed him right on the lips. She had kissed boys before, but never a demon. Hiei froze for a few moments while Nanashi held the kiss. When he snapped back to his senses, Hiei let her wrist go with a shake, placed both hands on her shoulders, and shoved her away. Nanashi hit the ground hard with a thud. Breathing heavily, she looked up. He had let her go. He had stop "killing" her, but she did not know what to make of his poker face.
"Slut's tricks," Hiei panted. "That's what you've come up with. Slut's tricks."
Nanashi could not help but look up at him. Not sure what to make of the situation. He stared down at her hard.
Hiei broke the silence, "Find your own way back." Hiei took off without her; abandoning her in the woods without any idea how to get back. Eventually Kurama found her after sunset. That day was the last day she was trained by Hiei.

In spit of the pain he caused and the brutal training he put her through, and then his cold aloofness to her from that night on, all that did not bother her as much as the kiss she gave him. She felt something she could not understand. It was trick to get him to let go, nothing more. She would find herself day dreaming about that kiss... about that sparks she felt. About more things they could have done. Things she concluded would never happen.
Nanashi snapped herself back to reality. Trudingly, she went through the apartment, to her own small bedroom, and plopped herself back first down on her bed and sighed. Thinking to herself, she wondered 'What to do for today. Homework? Nah. Yusuke won't be home for hours as usual. I never see my aunt before 9 o'clock. I supposed I could call Keiko or something.' She rolled over on her stomach, hugged her pillow and gruffed. That was when she saw him.
She screamed out in surprise. Hiei was standing there, between her bookcase and desk, looking at her intently; hands in his pockets. She sat up on her knees and hugged her pillow tightly to her chest.
"What, what are you doing here?" she whispered quietly.
"What do you think?" he replied just as quietly.
She looked at him curiously, wondering what he wanted. He walked over to her on her twin bed. He brought his face right up against hers. She fell back, startled. She was now sitting on her backside. Hiei huffed and steeled his nerve.
Hiei leaned his face down to hers and spoke softly, "I wonder if you've thought about what I've thought about?" With that, he kissed her. At first, she was stunned still. Gradually, she realized it was real and not her imagination. She began to kiss Hiei back. Hiei deepened the kiss, introducing his tongue into her mouth, while gently pushing her down to the bed. She felt a bit nervous because her school uniform skirt was half way up her thighs. Nanashi broke off the kiss by moving her head to the side and breathed deep.
Hiei stood up and caressed Nanashi's thigh. "I'll be right back," he purred.
Hiei walked out of her room and shut the door. Nanashi breathes heavily, realizing what was coming. What she wanted to come. Nervously, she sat up and looked down inside of her shirt and was miffed. She was wearing a hideous, old, white bra that day. If she was thinking what Hiei was thinking, she needed a better bra, stat. Quickly, she got off her bed and went to the top drawer of her dresser. Muttering to herself, she rummaged around until she found the bra she waited; a lacy, purple bra. She dug it out, and closed the drawer. With haste, she pulled her unifrom top off, unsnapped her old bra, took it off, and dropped it on the floor. Clumsily, she began to put on her lacy bra. That was when she heard the door open. She turned around, her breasts still exposed. Hiei was standing in the doorway, smirking.
As he sauntered over to her, he looked her up and down. She could not do anything but breathe heavily. When Hiei reached her, he bent down and picked up her old bra and threw it across the room.
"You won't be needing that," he said. Then, he reached over, grabbed her lacy bra, and threw it across the room as well. It landed next to the other bra. "Or that." He pushed her against the dresser, grabbed her face, and pulled in for a deeper kiss and began stroking the side of her waist. As his hand moved up, he pulled his face away and questioned, "May I?"
Nanshi nodded, too nervous to speak. Hiei tentatively reached his hand up to her breast and cupped and carressed it. Nanashi let out a soft moan and tried to stifle it with the back of her hand. Hiei noticed and spoke, "you don't need to be quiet. I made sure no one would hear us... Or walk in on us."
With that, Hiei kissed down her neck and chest until he reached her other breast. Being shorter than she was, he was the perfect hieght to comfortably align himself with her breast. Still carressing the other one, Hiei took her other nipple into her mouth and began to suckle it. As he did so, Nanashi's chest heaved with how he was making her feel. Hiei enjoyed touching her, growing a bit rougher as time went on. All too soon, Hiei removed his mouth and hand from her chest, and placed both hands on her waist. He then slid his hands down her backside and picked her up. Nanashi let out a little gasp. Still holding her easily up, Hiei walked them both over to her bed and dropped her down.
Nanashi propped herself up on her arms and watched as Hiei as he took his cloak and tanktop off. She liked what she saw. Once he was topless, he looked her over. He leaned over her, brought one knee between her legs, and kissed her more. Next, he pushed her down roughly and deepened his kissing. He wanted her to point where he could almost not control himself or his actions. He did not want to hurt her, much, so he had to remain in control of himself. He broke the kiss, and began kissing up and down her face, neck and shoulders. Nervously, Nanashi figured it was her turn.
Hesistantly, Nanashi pushed up against him. When he pulled up, she rolled him over and layed on top of him, french kissing him. Shakily, she stroked his chest and torso underneath her. As she stroked one of his nipples, Hiei reached up and grabbed one of her breast and squeezed. Together, they teased one another. Feeling distracted, Nanashi reached for Hiei's hand and removed it from her breast. Nanashi began to kiss down his neck and onto his chest and torso. She kissed and licked all over; not exactly sure where would be best, besides the nipples.
Eventually Hiei grabbed her under arms and pulled her back up so they were face to face. "I want you," Nanashi breathed. "Please."
Breathtakingly quick, Hiei grabbed her and brought her down at the head of her bed. Fumbling, he unzipped her skirt and pulled it off. Nanashi looked down and noticed she also had an old, ugly pair of panties on. She sighed annoyingly.
"What's wrong?" Hiei asked, looking up at her.
Nanashi brought herself back. "Oh... it's... um, nothing."
He gave her a quizzical look and pulled his hands away from her body.
Nanashi caved, turning red. "I don't like, um, what I'm still wearing...I hadn't planned for this."
Hiei chuckled. "Oh. I have." He reaches into his pocket and pulled out a condom. He layed it between her breast. He reached down and pulled off her panties; never taking his eyes off her eyes. "I don't think you're wearing anything anymore," he whispered as he stroked her inner thigh.
Nanashi began to breath deeply and brought her hands to her turning red face. She felt exetremely nervous on top of feeling so horny. Hiei brought his mouth up to her ear, cupped her mound, and questioned, "how do you want it little virgin?"
Nanashi pulled her hands away from her face in shock. "What?"
Hiei nibbled on her ear. "Like this?" he asked as he pressed his middle finger deeply inside of her, searchingly. Nanashi gasped in shock. When he cannot go any higher, Hiei realized what she meant by what. "You're not a virgin are you?"
Nanashi shakes her head and explained, "Just an old boyfriend, a a a human, from my old city. It was only a few times. I, um, didn't, uh..."
Hiei furrowed his brow. He was clearly not a fan on this news. He took his finger out of her and asked again, a bit more gruffly, "how do you want it?" When Nanashi did not reply, he asked, "fingers or tongue? Which do you prefer?"
"I don't know," she replied. "I've never, um, enjoyed..."
Hiei realized what she meant. He sat up straight. Smirking, he replied, "I'll fix that."
He brought himself down to the apex of thighs and set to work. Testingly, he teased her clit with his tongue. Nanashi had never felt anything like it. She did not know what she felt exactly, but she liked it. She felt as if she could not get enough air in her lungs and began panting. Next, his tongue went down a bit lower and licked testily. Hieii grabbed her thighs, pushed her legs apart more, pushed her folds out of the way, and thrusted his tongue in as deep as he could. She panted noisely. His tongue felt so wet and everywhere at once. Quicker than she expected, she coud not take much more of it. Hiei was relentless. She took a deep breath and came with a moan. Hiei pulled his mouth away and snickered. Lazily, he kissed back up to her neck. After that, he layed down beside her. "How was that?" He began to take his pants off.
Nanashi was not sure how to respond. She tenitatively rolled over to him and kissed him. The condom fell between them. Hiei took her wrist, gently as he could muster, and brought it to his cock. Nanashi, a little unsure what to do, nodded timidly. She would do what he wanted, but she was not sure how. She wrapped her hand around him and just squeezed. Hiei jerked and stopped her with his hand on her.
Hiei gritted his teeth, "a little to rough. Like this." He guided her hand around him and went up and down. When he was satisfied, he stopped guiding her and let her work on him on her own. He grew harder under her semi-novice hand. After a short time, he took her hand off of him and rolled on top of her.
He was about to enter her when he stopped himself. "Urgh, where is the condom?"
Nanashi fumbled and grabbed the condom that somehow had slid behind her shoulder. She handed it to him. Hastily, he tore the package open and slipped it on to his member. Hiei positioned himself, with her legs around his torso. "May I?" he asked.
Nanashi breathed "yes..."
He slid himself instead of her and laid his body down on top of her. He buried his face into her neck. She cried out as it hurt. It felt tight, like thick pressure. She was not sure if she could handle it. She began to whimper. Hiei brought himself completely down on top of her, pushing ever deeper. She gripped and scratched at his back in response to the pain.
She called out, "please. Slow down. Ah ha."
He stopped completely at first, swore, but then pulled out a bit and went slower. It still hurt, but she could handle it. She still gripped him and laid her head back against her pillow. Slowly, he was able to speed up and she was able to take it. He swore when he came. He pulled out quickly, pulled the condom off, and laid his head down between Nanashi's breasts. When he mustered the energy, he roused himself and kissed Nanashi on the mouth, roughly nipping at her bottom lip. He was not done with her yet.
Hiei shifted so he was beside her on her bed. He reached his hand down to her mound and slipped two fingers inside of her. She gasped because she was not expecting anything of the sort. She had never heard of a guy doing that before.
Hiei chuckled and commented, "if I don't do this to you, how will you know which way you like better?"
She came unimaginably quickly and he pulled his fingers out.
"If you want it, next time my hand first," Hiei spoke.
Nanashi had never felt so blessfully tired and achy at the same time. With little effort, she fell dozed off.

When she awoke, she realized she was dressed in her school uniform again and now tucked in under her covers. The sun was just beginning to set. She wondered if it was just a vividly wonderful dream, but then realized there was something in the crook of her arm. She reached over and grabbed the small package. It smelled feintly of herbs. Attached with a rubber band was a note reading: "drink this everyday." Nanashi, puzzled sat up. She opened the package and saw inside were tea bags, seven rows of four. Smiling, she realized her new lover wanted more, but also wanted to be safe.
