"Shouldn't we go after them?" Shippo asked.

"No. If Inuyasha is going to do what I think he's going to do, then it's better to leave them alone. One or both of them will harm us if we try to stop them." Sango shook her head.

"What are they gonna do?" The little fox asked curiously.

"You're a little young to understand." Miroku grew nervous. He followed Sango's lead to return to the village. "I just hope he knows what he's doing when Kagome finds out."

Meanwhile Inuyasha chased Sesshomaru into the forest. In the process other demons began to give chase. To which Inuyasha cut them down with ease.

"He's not some damn prize for you filth to grab!" Inuyasha yelled at the top of his lungs.

Sesshomaru almost tripped when he heard those words. In his momentary distraction a demon lunged from his left. He barely had time to twist before his poisoned claws raked across the body. The howl of pain music to his ears.

"Look out!" Inuyasha warned before he tackled Sesshomaru out of the way of another demon.

Now pushed against a large tree the Lord of the West was now in a very peculiar predicament. If he didn't just have the breath knocked out of him he would be moaning. Instead he gasped at their closeness. He tried to fight off the invading scent by releasing his own.

This of course attracted more demons.

"Damn it, just submit to me already!" Inuyasha snapped, grasping a pale wrist to prevent Sesshomaru from attacking him. Their scents were at war with each other. All around the demons paused, watching, hoping that Sesshomaru would be theirs instead.

But his brother was proving to be stubborn.

And Inuyasha closed his eyes. When he next opened them his eyes were crimson red, and his fangs elongated. Sesshomaru blinked and suddenly the golden yellow color was prominent. In his shock his scent gave in and suddenly he was fully enveloped in the half demon's scent.

Begrudgingly the other demons left. When the last one was gone Inuyasha reined control in. It proved to be difficult. Being this close to Sesshomaru as that sweet scent had his head reeling, his skin burning as they touched, their bodies reacting for the other.

Despite it all Inuyasha's eyes returned to normal. At the change before him Sesshomaru snarled.

"What do you want? Just to torture me? Make me beg while you mark and claim me while you use me like all the other filth that wish to be in your place?"

"I'm not that cruel and you know that Sesshomaru. Now stop it." Inuyasha grunted as his own body moved against the other, earning a half moan as Sesshomaru forced it back.

Memories of their first meeting passed between them. Where Inuyasha had inadvertently taken care of him at his most vulnerable. In the process he drove away other demons wishing to claim the sweet scent.

"Then why are you doing this!?" Sesshomaru hissed. He was being driven crazy. His whole body shook with anticipation. The primal need was too much to bear and he knew it was driving his brother equally as insane.

"Making sure none of those filth as you call them claim you." Inuyasha stared at the flushed state the other was in. The usually stoic face was blushing on his cheeks, his eyes darkened with lust.

"So what, you planning to just stand here like this?" Sesshomaru glared.

"Unless you want me." Inuyasha offered with a chuckle.

"As if." The other snorted in disgust.

"Really? Because you look like you do."

Sesshomaru looked away. In doing so his neck was exposed. His pheromones reached Inuyasha's nose and before he could stop himself his mouth attached to the pale neck. Sesshomaru tensed, but otherwise didn't fight the action.

A tongue licked at his skin and Sesshomaru couldn't bite back the moan in time. Fangs grazed gently against his skin that left him breathless as he struggled to gasp for more air.

Sesshomaru closed his eyes while his hips moved against the one who trapped him. The friction earned a groan from Inuyasha. Suddenly his free hand grabbed Sesshomaru's leg and lifted it up so their bodies could be even closer.

The new angle made Sesshomaru keen. He could feel the hardness against his wet entrance. His body had been releasing slick since he was pinned against the tree. And suddenly he didn't care who this was anymore as desire reached greater bounds.

"Just get on with it already!" Sesshomaru snapped.

Figuring that would be the best form of consent he would get, Inuyasha relased the wrist and leg to scramble with the armor. After a moment of clarity that his hand wasn't captive anymore Sesshomaru began to help him.

After the armor it was only a matter of seconds before clothes and swords were discarded without care. Inuyasha couldn't help himself but to explore and tease every part of Sesshomaru's growing exposed body.

When he grew too impatient when nothing was actually happening Sesshomaru took matters into his own hand. He managed to push Inuyasha down onto the ground. The younger half yelped at the sudden change. Then a second later Sesshomaru was straddling him and Inuyasha's angry outburst died in his mouth.

Slowly Sesshomaru lowered himself. There was no need for preparation. His body had released enough slick to ease the pain. Inuyasha bit back the groan as the warm walls tightened around him. He couldn't help but stare up at Sesshomaru as he threw his head back with a moan.

"Beautiful," Inuyasha gasped.

More so than the first time they met. Inuyasha had thought him beautiful then. But something in his beauty held a regal presence that had sharpened from age. For a brief second Sesshomaru glanced down at him from the statement.

There was confusion and surprise in those eyes. Did Sesshomaru really think lowly of himself? Inuyasha will have to ask later. Although he can imagine where that spawned from, now wasn't the time for answers.

Deciding that letting him think about it might give Sesshomaru second thoughts, Inuyasha grasped pale hips and moved them down. In the same instance he thrusted up.

The gasp lead to more moans as they moved as one. Eventually Inuyasha let go of those bony hips. He watched as Sesshomaru took full control. It was memorizing to see the usually stoic demon become so undone with his primal desires.

He watched as Sesshomaru grew frustrated chasing that high and yet unable to find release. Inuyasha smirked before he reached up and switched their positions. Sesshomaru snarled at first, glaring.

"You like control. But that's not what will get you off." Inuyasha chuckled darkly before he yanked on softer white hair as he thrusted harder. "I know you Aniki, you need control ripped away from you."

Sesshomaru's retort died in his throat as he was being rammed into roughly. The fight in him gave into the power demonstrated. He sensed his inner demon submitting almost too easily.

And he was right. Sesshomaru felt his mind go blank while all of his senses were assaulted. His nose was filled with nothing but Inuyasha. His ears heard gasps and moans. He couldn't fully believe they were his own, but as he looked up at Inuyasha, he was holding back to hear all of Sesshomaru.

Lips claimed his neck again. Sesshomaru felt his eyes flutter shut. His breath hitched as he felt fangs teased him. For a split second Sesshomaru wondered if he actually would mark him. He sensed the other thought about it.

And yet he didn't take the chance. Instead a hot tongue licked. And for some reason he found it endearing. The action brought him closer to the edge.

"Inu..." Sesshomaru grunted, trying to hold onto this feeling before he lost it.

Encouraged at the sound of part of his name, Inuyasha went all out. His hands roamed the writhing body underneath him. He began sucking on the pale neck. Inuyasha was careful not to bite as he did so.

He felt his inner demon struggle to claim and mark. It was their right. Inuyasha held that side of him back. Doing so his throat released growls and snarls.

"Inuyasha!" Sesshomaru tensed as he closed his eyes. His cry earned a deep snarl from the alpha.

Fangs grazed his neck. For a split second Sesshomaru thought he would give in. Instead Inuyasha reached his own peak.

"Sesshomaru!" He shuddered as he came.

Under normal circumstances, Sesshomaru would have been pissed. They had Naraku to defeat. Now wasn't the time to have pups. Let alone raise one in a broken family when the father didn't mark him. Sesshomaru would have sent Inuyasha running.

But as he was in the heat of the moment, he couldn't find it within himself to care. Not even as Inuyasha knotted. Sesshomaru moaned weakly, already feeling overly stimulated.

"Shit...I'm sorry." Inuyasha panicked.

"Don't make me regret accepting you, Inuyasha." Sesshomaru glared.

"You...you accept me?" The hanyou blinked.

"We wouldn't be in this position if I didn't, would we?" He meant it.

"No but...I just didn't think you would actually say it." The admission had shaken Inuyasha to the core. Even his ears lowered in distress.

Sesshomaru huffed. A sense of his normal self returning. Now that most of his heat was satiated, his mind wasn't so clouded. And despite it all he wasn't at all too bothered by this situation as he thought he would.

"I assume you can guess, when we first met I was in heat." He began, earning a nod.

"Yeah, I realized that when I smelled your scent. It was the same as that time. I always wondered what that was about, or if it was my imagination."

"Your body released your scent to intermingle with mine. In doing so you drove away potential demons searching for me. So even though you weren't of mating age, you still acted to protect me. I suppose that left an impression with my inner demon." Sesshomaru knew this to be true.

"Then why were you such an asshole?" Inuyasha pouted.

"Because I had to see the potential to be true. That you'll be strong enough. Even though you proved a hundred times over, I am not one so easily persuaded."

"Tch. Looks like all it took was an act of chivalry. Who knew you were so formal?"

"Don't make it sound like an act of charity. Or I will slice you off."

"Yeesh. And there's the Aniki I know." Inuyasha chuckled with a sly grin. "So...how long does your heat last?"

"With help, around three days. Otherwise it would be a very long week."

"So I've only got three days with you?" Inuyasha seemed saddened by that fact in comparison to a whole week. "Then I guess I gotta make them count, huh?"

Sesshomaru knew then this was going to be the longest three days of his life.
