My first story about Sesshoumaru and Rin... =D

Actually, I wanted to make a one-shot, but because I want some RinxSesshoumaru, I will make some chapters.

If you find some grammatical mistakes or wrong vocabulary usage, tell me, I'll edit it... :D

Okay then, let's just start the story, hope you enjoyed it!

"Sesshoumaru-sama," Rin called him. "My tummy hurts."

Seshoumaru looked at her. "Take off your clothes, Rin."

Rin took it off without any hesitation. No external injuries, he thought. "Where does it hurt?" Sesshoumaru asked her kindly. Rin led his hand to the place which hurt the most. "Here," she said.

Sesshoumaru tried to remember the lessons which were taught to him when he was young. He used to remember where it would be hurt if he got diarrhea, constipation, etc. But, the spot which Rin led him to was not known to him.

"It'd be better to take you to that woman of Inuyasha. Tomorrow we shall see her," Sesshoumaru said. "Just eat, Rin, maybe it will ease the pain."

Rin nodded, she put on her clothes and went to do as she was told.

Morning had came. It was usually calm for Sesshoumaru's group, but not today.

"Seshoumaru-sama! Seshoumaru-sama!" Jaken cried while looking for his master.

Suddenly, Sesshoumaru appeared behind him and said, "What is it, Jaken?"

"Rin, Rin, she suddenly had a stomachache when she woke up. Since an hour ago, it wouldn't stop!" Jaken quickly explained. Sesshoumaru went to Rin immediately.

The girl was in pain, her hands were on her stomach as she tried to stop the pain. Tears were flowing from her eyes. Sesshoumaru kneeled and took the girl in his arms, then he flew away.

On his way to Kagome's place, Rin was still in a great pain and breathing heavily.

"Will... Rin... die, Ses-shou-maru-sama?" Rin asked him.

"Idiot, don't ask such a silly question," Sesshoumaru replied as he looked into her for a second.

Then, Sesshoumaru felt something wet and from Rin's body there was a smell of blood.

"Rin, do you have any injuries?" he asked her.

"No," she replied.

Sesshoumaru put Rin on his left hand, and then looked at his right hand. It was wet by blood. Now, Sesshoumaru understood what happened to her. The girl had grown up. It was her first period.

Sesshoumaru let out a sigh.

"You're not going to die, Rin," he said. "You are just becoming a grown up. Don't worry."

Sesshoumaru hurried his way to Kagome.

Sesshoumaru entered his brother's house without knocking at the door. He found Kagome sitting in the middle of the room and immediately gave Rin to her.

"It's not my place to teach her about womanhood," Sesshoumaru said. "I would leave it to you."

Kagome smiled at him and nodded. "Put her there," she said while pointing at the corner of the room.

"She'll be okay right? She has been in pain since early morning," he told her.

"For some people the first time could be uncomfortable. It will take some time to adjust with it," Kagome told him. "You can wash your hand for that blood is consider dirty."

Sesshoumaru went out of the house and washed his hand, then he picked a very familiar smell.

"Sesshoumaru! What are you doing here?" Inuyasha asked.

"It's none of your business, Inuyasha," Sesshoumaru said.

"You asked Kagome for help, that meant you must show your thanks to me also!" Inuyasha said.

"So, you've already known why I am here. I will never say any words of gratitude to you," Sesshoumaru said. "You didn't do a single thing for me."

"But, Kagome is my wife and I let her help you!" Inuyasha said. Sesshoumaru turned away and left his half brother shouting at him and kicking the ground.

Sesshoumaru was in Inuyasha's house. Kagome let him stay there for the night, of course Inuyasha didn't agree, but after a few "Osuwari", he agreed. Sesshoumaru was next to Rin. He leaned his back against the wall. He watched Rin sleeping and sometimes put his hand on her forehead. Hoping that she would not get a fever because she was sweating all over her.

When dawn nearly came, he gave her a kiss in forehead and gently caressed her cheek.

"Be well soon," Sesshoumaru muttered. Sesshoumaru left her side and went out of the house, Inuyasha's eyes followed him.

Sesshoumaru went to the river to wash his face. Inuyasha was following him.

"Don't tell me you like the little girl," Inuyasha said. "Not as a father anymore but as a woman. She is now a woman, right?"

"Don't be silly, Inuyasha. This Sesshoumaru will not fall for a petty human," Sesshoumaru told him.

"You know her inside out and for this whole time she had been so loyal to you. I'm sure she will be your mate if you ask her."

"She does whatever I tell her. That, too, I will be able to get without asking her. But, as I told you, I have no interest in humans," Sasshoumaru explained to his half brother.

"Okay then, if you don't want her to misunderstand you, just don't act so nicely in front of her. You're lucky I'm the only one who knows about you kissing her forehead and caressing her face all night long. If the girl had known about that, I'm quite sure she would have been thinking the same thing as I do now," Inuyasha told Sesshoumaru and then left him alone. Sesshoumaru couldn't say any words of denying. It was the first time he had agreed with Inuyasha. Inuyasha was right, he was giving people the wrong impression. If Rin knew about this, he wondered what she would think of him.

Sesshoumaru went back to the house, he found that Kagome and Rin had got up. He went to Rin and asked, "Rin, are you well today?"

Rin nodded and smiled at him. "But, it still hurts a little...," she added.

"The blood will come out from her for a few days, Sesshoumaru. It'll be better for her to stay here. I'll teach her to be a good woman," Kagome said.

"I'll pick her up in a few days," Sesshoumaru said.

"Rin, from now on you need to be more careful about your body. The body will start to produce hormones which will make a few changes in your body. For example, now you have a little mound in your breast, but after this, it will be bigger soon, and some parts of your body will be covered by hair. That's normal," Kagome explained.

"Oh no! That's bad," Rin said. "Don't you think it's disgusting?"

"It's normal, you'll get used to it," Kagome said. "Now, I'll tell you in short about reproduction."

"What's that mean?" Rin asked.

"Reproduction is, uhm,...," Kagome trailed off. "Ah! It's how you make baby!"

"Oh, I see...," Rin nodded. "Easy, you just have to sleep next to a man. Then, a baby will be in your stomach!"

Rin laughed. "If you want to explain about that, I have already known about that, Kagome-sama!"

Kagome could only give an awkward laugh. "Well, that's not really true, Rin."

"Which part is wrong?" Rin asked. Her face shown a disbelief look when Kagome said she was wrong.

"It's not as simple as sleeping next to a man. Okay, I'll explain quickly. Man, of course, has their own organ like we do," Kagome said. "A man's thing must enter a woman's, then he must spread the sperms. When one of these sperms fertilizes the ovum, then we will get pregnant."

"So, a man's thing means the one they had in this place right?" Rin asked while pointing at her womanhood organ. Kagome nodded. "I saw it several times in my villages. Boys running without any clothes, and I saw it. I think I would not want it inside this thing of mine," Rin said.

"Rin, I remember the last time you were here, you also running to the river without clothes. From now on, you must not do that again. Don't take off your clothes except you went to have a bath, you're already twelve. And, don't take a bath with a man, that includes Sesshoumaru," Kagome said with her stern face. "Understand?"

"Why? Why can't I take a bath with Sesshoumaru-sama?" Rin asked. She felt disappointed.

"He is a man. And so, having a bath with him is a big no no," Kagome shook her head.

"What about Jaken-sama?" Rin asked.

"Well, he didn't look human at all...," Kagome said and thought about it. "Jaken is okay. He's not that manly anyway."

Rin and Kagome laughed. "It's still disappointing. I can't have a bath with Sesshoumaru-sama anymore..."

"Now, you need to pay attention to your hygiene, especially when you're having a period. First, when the clothes had too much blood, you must clean it yourself and wash it until the blood washed away. Second, you need to prepare many clothes to replace the one you use. That is the main thing," Kagome said.

"I'll do that," Rin replied.

"Oh yeah, that breast of yours will be hurting a bit when it grows, so don't be panic if it hurts when you touch it," Kagome told her. "You need to get a more suiting clothes you know. The kimono you're wearing is too small for you now."

"I'll buy one if I have the money," Rin nodded.

"I'll give you one later," Kagome said.

"Thanks," Rin said.

"Tomorrow, I'll teach you how to clean the blood quickly."

A few days later, the blood had stopped coming out. That was the end of her first period. Rin felt her body became light and her mind happy. Sesshoumaru hadn't picked her up, so she stayed longer in Kagome's place.

"Rin, let's wash your hair. You must clean your hair you know. It's tangled and hard to be combed," Kagome said to her.

Rin nodded. She followed Kagome to the river and Kagome washed her hair for her. "You need to learn to wash your hair by yourself. Today, I'm doing for you."

Rin let her hair dried by the wind. When she stroked her own hair, it feels so soft and smooth. She stroked it over and over.

"Like it?" Kagome asked.

"Yes, definitely. It feels so nice," Rin said.

Kagome giggled. "From now on, you must clean it regularly, okay?"

Rin smiled and nodded.

"Rin," Sesshoumaru's voice was heard. Both Kagome and Rin turned their eyes to the source.

"Sesshoumaru, you come at last. We've been waiting for you," Kagome said. "Now, she can continue her journey with you."

"Sesshoumaru-sama!" Rin ran towards Sesshoumaru and hugged him.

"I see, you look well...," he said to Rin.

"Yes, Sesshoumaru-sama. Rin is not feeling hurt anymore," she said.

"Thank you, Inuyasha's woman," Sesshoumaru said to Kagome.

"Your welcome. I'm happy that I can help her change into a woman," Kagome said. "And Sesshoumaru, I want to speak to you too."

"Rin, can you return to the village for now? I'll pick you up later," he said.

Rin went running towards the village. Sesshoumaru and Kagome's eyes followed her until she was vanished from their sight.

"What is it?" Sesshoumaru asked.

"I know it's been a habit for you, Jaken, and Rin to take a bath together, but now, she is a woman, don't do that again, that's the most important. I'll give you a list of things which you should not do. You can read right?"

Kagome handed the paper.

"And Inuyasha told me that you like, no, love Rin," is that true?" Kagome asked.

"That is not."

"I see. If it somehow becomes true, don't touch her until she reaches the proper age," Kagome said to him. Her face looked stern.

"Listen, I never wanted to take her as my mate," Sesshoumaru said to Kagome with the same stern face.

Kagome sighed. "Why do you keep her?"

Sesshoumaru thought for a second and found no answer. "No reason."

Kagome sighed for the second time. "Just go, don't let her wait for too long."

And Sesshoumaru went to pick Rin up.

"What kind of change could this event brought to my relationship with Rin? This is just so silly, everyone keeps asking whether I love her or not. Of course not, why would a great demon like me fall for a mere kid... That's just not make any sense!"

TBC

Well, this is the first chapter...

I don't rate it as an M, because it's just a normal explanation, like what we heard in school. And I don't use the real words for the explanation, so that this fic would be able to enter the T rate. The thing is, I don't want to make a lemon. It's just going to be a love story... :D

Give me some reviews if you want to! I'll appreciate them so much.

Thanks for reading.
