Okay a few things about this chap-

1) yes this is still an Inu no Taisho/Kagome fic. however there will be multiple pairings until the end of the story.

2) Sesshomaru is an inu- I don't know if people have sat down to casually observe their pet dogs when one of them is in heat, but they aren't discriminate about what they 'do'. Male, female, young, old, littermates or not- so I was basing what happens to an extent between Sesshomaru and Kagome in this chap on that knowledge.

3) Sesshomaru may have done some hentai things to Kagome, but he did it for a reason. Read the chapter carefully before drawing your conclusions.

Naraku, Inuyasha and Kikyo came up with the plan to force Kagome and Sesshomaru into a demon breeding state to cause irreparable harm to them.

Kagome was especially a target in this. And if Sessho had given in, he would have not only lost his honor and his pack, but Kagome as well. However he was able to hold back much of his urges due to Kagome's age and out of concern for her wellbeing.

(***************************************************************************************************)

Two weeks later-

A barely dressed Sesshomaru sat on his knees with both of his arms extended fully so that his clawed fingertips were digging into the rocky wall of the cave that he had created as his red, and turquoise eyes stared at the small figure of the unconscious form of his imouto while he wracked his brain trying to figure out just what the hell had happened.

Much of his memory was a blank after their return to the camping spot that the monk, slayer and kitsune had been setting up for their pack.

Don't get him wrong, he knew that time had passed. He was even acutely aware of how much of it had passed. He simply didn't know why his memory of that time was coming up blank.

But from what his demonic eyes could see of his young imouto's state of undress coupled with the various scents that he had not indulged himself in quite a while as well as the unmistakable look of the fang markings on the hollow of her shoulder- it looked as if...he had mated his imouto?

Well, not physically at least. He would imagine that her age and physical lack of maturity had probably saved her from a full mating. But he had marked her as his mate anyways.

Slowly feeling his beast recede within his mind, he sat there- hovering, if truth be told, over his imouto. Watching her face as she slept a dreamless sleep.

His scent clung to her everywhere. Just as hers covered him.

Taking a moment to slowly removed one hand from the wall of the small cave, he quickly realized that that was a very bad idea since he nearly collapsed on top of Kagome's small, fragile form before he could catch himself with his hand.

"Oh damn." He muttered softly as he quickly accessed just how weak his body was at the moment by the slight trembling/aching, and burning muscles and such in his limbs. He felt so weak. He never felt like this unless it was breeding season.

Just what the good goddamned had happened upon their return to the camp? He wondered irritably as he leaned down a little bit more, whimpering slightly at the protesting aches and pains in his spine, shoulders and neck as he did so- and licked the place on Kagome's body where he had sunk his fangs into her soft ivory skin.

Kagome's body tensed slightly upon the contact on his tongue on her skin, eliciting a soft whine from him. Almost as if he were trying to apologize to her for whatever he had done when he heard her gasp out in a broken voice, "N-Na-raku..." Hearing the name of their accursed enemy leaving her lips caused him to suddenly jerk back and sit up so quickly that he miscalculated the distance of the cave roof and managed to hit the back of his head on it. Earning a hiss of pain from the Daiyoukai.

He might have tried to rub the back of his head, but dammit he was hurting and it took far too much effort to lift his arm to do so. So he didn't bother.

Still, the throbbing in the back of his skull aside, the name of his sworn enemy brought back a slew of memories that not only made the inu cringe, but swear and blush with shame.

Just two weeks ago, he had finished up his usual bathing ritual with his imouto and the monk when the monk had gone back ahead of them to make sure that his fool half brother was staying out of trouble. Leaving him with his imouto for a little bit longer.

Which wasn't anything unusual there.

After the two had dressed, he had then picked her up in his arm and sped off towards camp only to find, that upon their return- the whole camp had fallen into absolute chaos.

Naraku was there, as was the dead priestess- the half breed's bitch and of course his little brother were all present. His brother had somehow incapacitated both the little kitsune and the fire neko, and the three were in the process of watching the monk basically attack the demon slayer.

Sesshomaru had been so startled by the happenings that he had dropped his imouto and charged into the clearing to pull the monk off of the slayer and do something about him, when her cries had suddenly changed. As had her scent.

She was feeling no pain or distress. The whole reason he had thought that she was had been because of how startled she had been when the monk had grabbed her and torn her kimono open.

No- the slayer was fine. As was the monk- though he made a mental note to take them both to task for this debacle later.

However he never got the chance. He heard Kagome let out a startled sound and turned to see the clay bitch forcing something in a vial down her throat and then once she was certain that she had swallowed what was in the vial, she had thrown his imouto to his half brother and Naraku.

Sesshomaru had of course gone after them and wrested her back from them. But by the time he did, he had noticed that something was painfully wrong with his precious imouto. She was barely aware of his presence. Her eyes were glazed over, and her scent... Dear god.

Her scent had all but scared him senseless and sent him into a rage all at once.

The usually floral scent of her had changed into something that he had been dreading as she aged and matured. It had changed from floral to honeyed, laced with the faintest traces of her incredibly strong power. There were other things lacing her scent as well- things that made him panic and instinctively cradle her small body against his chest as he did the only thing that he could think of to get her away from the dangers that the two half breeds and the undead one represented to her being- and he ran.

But not before he had drawn one of his swords- Bakusaiga- and thrust the blade into the ground and poured enough of his youki into it so that when he did so, it would create a barrier strong enough to withstand his half brother's blade, the miko's power and Naraku's cunning.

This way the rest of his pack would be safe from them until he could return.

With that done, he ran as fast as he could- dodging arrows and his foolish little brother- whom he would kill later for this betrayal- as well as Naraku's hell wasps.

He wasn't sure how long he ran, or when exactly he managed to shake the three. But when he finally did, and began to slow his pace a bit- he knew that something was wrong with him.

Under normal circumstances he never would have slowed his pace if he were to run from something. The only times that he had ever done so were when he was badly injured and needed to find a place to hide himself away in so that he could heal, or that one time he had been bespelled by one of the demonesses of his court in his youth.

Slowing his pace even more, he quickly took stock of any and all injuries that he may have sustained from the three while he had been attempting to leave so that he could save his imouto and found that he had been shot in the back of one of his shoulders by one of the miko's arrows.

He didn't bother pulling it out at first. Especially since he was suspicious of why her reiki wasn't purifying him. Or at the very least making some sort of attempt to anyways.

It wasn't until Kagome's scent got stronger and his lower body had begun to ache and throb with need that he even realized what had been done.

Growling softly in annoyance as he reached up and savagely yanked the arrow out, he took a moment to stare at the blue tip covered in his blood in contempt before using his acid claws to melt it.

So Naraku and the others wished to force his body into a breeding state. Glancing down at his young imouto he could only imagine the horrors that they had planned for her in her current state. Which meant one of two things.

Either they had expected for him to be overcome and rape Kagome. Or he would fail to recover her from Naraku and his half brother and they would rape her.

"Fools." He muttered as he felt himself starting to sweat a little bit from exertion. Naraku and the other two obviously didn't know just who they were dealing with.

There were ways around being in a breeding state. Not all of which were sexual in nature.

Besides, his affection for the small miko in his arms would always win out over the needs of his body. He would never force himself on her in such a disgusting manner, but at the same time he wasn't all that sure what to do with her as she was.

If the contents of the vial that she'd been forced to drink were like the tip of the arrow that he'd been struck with, then he couldn't just do nothing. Especially if her body was being forced into a demon breeding state. Such things were horrific for demons. He could only imagine what would happen if a mortal being was left to suffer such a thing. And frankly he would- no, couldn't leave her to suffer them. Not when she could suffer irreparably because of it.

He would lose her if he did. And that frightened him, though he would never say so.

Which only left him with one or two options. Both of which were...difficult to resign himself to. But once he did resign himself, he made quick work of finding a nice secluded area and then hollowing out a small cave.

And it was small.

There was barely enough room for him to sit upright. Much less dwell in close quarters with a female in need.

Knowing that he was setting himself up for excruciating agony was one thing, but carrying through with the course that he had decided upon was another thing entirely. And it was...strangely fulfilling as well.

The moment that he'd cleared out the rocks and pebbles for the small makeshift den, and crawled inside, he had carefully set his imouto on the ground and begun to back away from her so that he could plan out his next move when she had leaped to her feet and pounced on him with such speed that it had left him dizzy.

He had been more than happy to sate her needs and see her through her current condition, truly he had. He felt no fear, nor remorse, embarrassment, or disgust like many others of his kind might over what had happened between them. He felt no need for those useless emotions since they did nothing but cause problems.

And he would not have his imouto hating him because he was 'feeling' something that he didn't actually feel. He was an inu and a Daiyoukai for gods sake!

It wasn't all that uncommon for an inu of his status to rut or even mate with a sibling. So he had nothing to feel badly about. And he would inform his imouto so the second that she awoke and was curled up in his lap after being fed.

He would also have to make her understand that she also had nothing to be ashamed of. The situation that they were now in wasn't one of her wanting or making.

Still...even though Kagome was now his mate, he would not be able to claim her as such until she turned at least twelve or thirteen. And even then, he would have to be very careful of how fragile she was. In the meantime he would just stick close to her and protect her as a mate/older brother should and hope for the best.

Sighing, he ran clawed fingertips through his long unkept silver hair and then realized that he had somehow managed to lift his arm as his world shifted and he suddenly found himself falling over, luckily missing Kagome entirely and hitting the cave floor next to her with a heavy thud where he simply stayed until he felt his strength slowly beginning to return at which time, he then slowly sat up again and crawled out of the cave to go and hunt for his mate.

She would likely be as weak as himself when she awakened, and the food would be welcome to help her regain her strength.
