I DO NOT OWN INUYASHA!

Yes, I wrote another one. What can I say, I love my favorite OTP! This story came to me in a dream. Thought it was worth writing. Enjoy!

Chapter One

"Inuyasha, are you ok?" Kagome cast her friends a worried look.

"I'm fine," Inuyasha grumbled.

"You're not fine. You keep rubbing your back. Did you hurt yourself when you fell down that cliff?"

Inuyasha growled. "I didn't fall. The rock gave way. Next time you can chase your own damn hat."

"It's not my fault the wind blew it off my head."

"Don't wear things that can get blown off like that then!" Inuyasha stood from his place by the fire and walked away into the trees.

"Inuyasha! Where are you going?" Kagome stood to follow him.

Sango put a hand on the girls arm and pulled her back down. "Leave him be. You know how he gets when he's hurt. Just leave him alone."

Inuyasha wandered until the moon was high and the forest was dark. He needed a break from the humans. As much as he cared about them, sometimes he just needed time to himself. He paused his walk and looked up at a rock formation. He knew where he was. There was a hot spring nearby. He angled toward it. His back was a solid ache. He had felt something crack when he had tumbled down that damn cliff.

The hot water helped him relax. But his back still hurt. Which was odd. Even if he had broken something, it should have been mostly healed already. Laying back in the water, he just let himself float. He focused on his aches and tried to pinpoint just where he was hurting. His ribs hurt low on his right side. Something in his lower back was a sharp pain. And he had a weird ache low in his pelvis.

What was that? Had something hit his stomach at some point? He moved to sit on the side of the pool and looked down at himself. He did have a few bruises. He pressed against his belly just above his groin. The ache was deep.

"What are you doing here?"

Inuyasha looked up to find his brother on the other side of the spring, looking at him strangely. "Bathing. Go away." Ignoring the demon, he went back to prodding the strange ache.

Sesshomaru tossed his clothes over a low tree branch and eased himself into the hot water. He settled back and watched Inuyasha. "This must be your first time if your belly aches."

Inuyasha frowned and looked up at the man again. "First time for what? And why are you still here? Go away."

"Your first heat, you stupid hanyo. And I came here to bathe, so I am going to bathe. I couldn't care less if you are here." Sesshomaru closed his eyes. He just wanted a peaceful swim. He hadn't expected to find Inuyasha at his favorite spring. He especially hadn't expected to find him giving off the mild scent of an Inu in heat.

"What are you talking about?" Inuyasha got back into the water.

Sesshomaru cracked an eye open. "Smell yourself."

Inuyasha frowned but put his nose against his wrist. There was something odd about his scent. "What is that? Why do I smell weird?"

Sesshomaru sighed. "You know nothing about what you are, do you?"

"What I am? I'm a hanyo, as you love to point out every chance you get."

"That isn't what I'm talking about. I'm talking about the fact that you are an uke."

Inuyasha gave a startled laugh. "The fuck I am. There's something wrong with your nose if you think that." Inuyasha shouted in pain as his chest and face collided hard with a rock at the edge of the pool. "Let go of me."

Sesshomaru had Inuyasha's face pressed against a large rock. The young hanyo's struggles were not helping him keep control over his Inu. "Hold still, Inuyasha."

"Fuck you. Get off of me." He reached back and raked his claws over Sesshomaru's thigh. He whimpered in pain as his face was slammed into the rock, breaking his nose.

"I told you to hold still." Sesshomaru took a deep breath, fighting for control.

Inuyasha growled and continued to struggle. Sesshomaru's hand was wandering his body. "Stop touching me, you fucking perv."

"Please, hold still." His hand moved around and caressed the hanyo's firm ass.

"I can't hold still with you touching me. Get the fuck off of me."

Sesshomaru pushed a finger against the hanyo's tight hole. It slid in and the boy trembled as a long, low moan escaped him. "Feel's good, doesn't it?"

Inuyasha felt himself flush with shame and embarrassment. What the fuck had just happened? "Stop. Please."

Sesshomaru let the boy go and moved back across the pool. "You're an uke having your first heat. That is why your belly aches. It is also why those bruises aren't healing. And why your body just trembled with pleasure from something as simple as a finger in your ass."

"Fuck you." Inuyasha huddled where Sesshomaru had left him. He felt violated.

"The heat has just started, but your scent is enticing." Sesshomaru stood near his clothes, wringing the water from his hair. "Find a good place to hide. A very good place. The last thing you want is to bring even more shame to yourself by getting with child by rape. The heat will last five days."

Inuyasha watched Sesshomaru pull his clothes on with a sense of dread. "Don't leave me alone."

"I would help you if I could. I much as I dislike you, you are my brother. But your scent entices me as well. If I am near you for too long it will be I who rapes you." Finished tying his obi, he looked back at the boy. He looked terrified. "There is a cave to the east, about half a day's walk. There is a large boulder in the inside that can be moved to cover the entrance. It won't stop a determined demon from getting in, but it will offer you at least some protection."

"Please, Sesshomaru. Don't leave me." Inuyasha wrapped his arms around himself. He felt disgusted with himself.

"I told you why I can't do that."

Inuyasha watched his brother walk away. He quickly got out of the water and pulled his clothes on, not caring that he was still dripping wet. He turned to the East and ran. He had to find the cave. He had to find somewhere to hide.
