Author's notes:

I don't even know if dog demons have a specific mating season, much less the details. The characters, the settings, and the relationships are Rumiko Takahashi's, but the plot came from between my ears somewhere.

I love reviews!

Nameless characters are original characters. The only original character that has a name is Setsu, and don't worry, she's a sweet old lady, not a Mary Sue. Keep in mind that I will not always refer to each character by name, even the ones that are not mine and do have their own name. For example, I've been known to refer to Lord Sesshoumaru as: Lord Sesshoumaru, Sesshoumaru-sama, the demon lord, the youkai, the inu youkai, the dog demon, and the inu (only done that once so far). So, just because I'm not using a character's name when they first get introduced, doesn't mean that character doesn't have a name.

Chastity Challenge-

Ch. 1 If You Can't Stand The Heat

"That's it! These demons are going down!"

"Master Inu Yasha! Wait! You mustn't hurt them!"

"What? Myoga, when did you- Ah!" Inu Yasha jumped away just as a lust driven female dog demon lunged at him. "You were saying, Myoga?"

"Well, I was going to check your location like I always do at the beginning of this season,"

"What are you talking about, it's the middle of fall!"

"Yes, but it's the beginning of the dog demons' mating season."

"So what? Why does it matter where- I SAID BACK OFF!"

"It matters, because it's important that you stay far away from Sesshoumaru's territory!"

"Why?"

"Because! He'll be very territorial at this time; besides, female dog demons are notoriously… aggressive, in heat. That's why these demons keep trying to pounce on you!"

"That still doesn't explain why I can't fight them."

"Because, it wouldn't be fair! It isn't their fault that they get like this, even Sesshoumaru shows them some mercy."

"Wow!" Inu Yasha jumped out of the way as a particularly strong female attempted to get his attention by taking a sharp swipe at his neck. "What the hell?"

"Run!"

"I never run from a fight."

"If you don't run this so called 'fight' is going to turn into an orgy!"

For once, Inu Yasha did as he was told, and ran. Unfortunately…

"No, not that way! You're going straight into his territory!"

"What do you expect, I can't turn or they'll get me!" Inu Yasha ran as fast as he could, but just when he managed to gain a small distance, his legs felt like they were going to give out. He knew he couldn't keep this up for much longer. Just as he was trying to think of a way out of this, he felt a harsh tug at the back of his robe. Before he knew what happened, he was being held by the throat submerged in steaming hot water.

………………………………………………………………………………………………

Several large, disgruntled females crashed into the small clearing, and very suddenly forgot their prey. Right in front of them was a hot, natural spring, and in it, the most sought after male among the dog demons. And considering the fact that his clothing and armor were resting on a rock nearby, they probably weren't on his person.

"L-lord Sesshoumaru…."

"I am in no mood to entertain you. Leave."

"Yes milord!" The ladies cried in unison, before sprinting off in search of an alternative mate. At that moment, Inu Yasha pushed his way to the surface, and gasped for breath.

"What the hell-"

"The water helped throw them off your scent."

"Y-you helped me?"

Sesshoumaru shrugged.

"If I allow you to reproduce, I would have to wait for your offspring to grow, and then kill them. It is easier, and far more amusing, to nearly drown you in hot water and prevent you from reproducing."

"Arrogant prick!"

"Lowly half breed." Sesshoumaru sniffed, then lunged at Inu Yasha.

"What the hell?"

"Myoga!"

"L-lord Sesshoumaru, what an honor it is too-"

"Silence! Why is he here? I would not expect him to know better, but if you were with him you should have kept him away!"

"I-I did tell him, but it was too late, he was already being chased in the wrong direction, his only options were to keep going or be captured, and I figured this was the lesser offense."

"Hmm It- MOVE!"

What happened next was a bit too fast for Inu Yasha to see, and the splashing water didn't help. After shouting "MOVE", Sesshoumaru jumped out of the way, his fur covering himself in such a way as to keep this story pg, and at that very moment, a sender golden blur bounced off of Inu Yasha's head and lunged after Sesshoumaru.

"Oh dear!" Whimpered Myoga, "It's already starting to affect him!"

"What is?"

"The symptoms! During mating season, in order to encourage procreation, a dog demons body produces a great deal of a variety of hormones. For females, there is a heavy emphasis on those that increase stamina, aggression, and sex drive. For males, the emphasis is on those that put them in a lust induced haze, slowing reflexes and making them less alert, and therefore easier targets for potential mates."

"That's terrible!"

"It's necessary. Besides, most of these females desire attention and cooperation, otherwise there wouldn't be anything the male could do for them that they couldn't do themselves. So, it's not as though they ever force themselves on a male, they just… are not gentle in their seduction."

"Feh, that's an understatement. What the hell!" The female pursuing Sesshoumaru caught him by the hair, and yanked him to the ground mid jump.

"Run for it, Master Inu Yasha!"

"What? Myoga, what do you? Where did you? Feh, good riddance! What the- Ah!" Inu Yasha realized a little too late that the female who captured Sesshoumaru was not alone; her comrades tackled him before he had a chance to escape.

…………………………

Inu Yasha's mind was hazy; he couldn't seem to think straight. He was confused, and the only thing he could clearly determine about his surroundings was that it was warm, and someone close by was growling. Constantly.

He opened his eyes, and waited for the blur to fade, and then took stock of his surroundings. He was in some sort of clearing, with a huge bonfire in the center, surrounded by the scent of dogs. All around the clearing were male dog demons, nearly all of them tied up in one capacity or another. Inu Yasha himself was belly down on the ground with his hands tied behind his back. And sitting in front of him, with his hands tied to a stake in the ground, was Sesshoumaru, growling at anything that dared come near him.

"Wh-"

"Keep you're voice down!" Sesshoumaru hissed.

"What's going on?" Whispered Inu Yasha.

"Do to our territorial nature, mating season used to cause the loss of almost as many lives as it created. Many males were so busy fighting it would be days before they ever got around to mating. The females got sick of it, so about two centuries ago, a group of female warriors started just rounding the entire male population up, and now the females just pick and choose whom they wish to mate, and no one fights. The female population has decreased considerably, so the females don't fight among themselves because there are plenty of males to choose from."

"Why do the guys put up with it?"

"Most just want sex."

"And you?"

Sesshoumaru snarled at a female who wandered a bit too close in her shopping around, before replying.

"I do not 'put up with it' as you say. I was captured, and I am waiting for the heat season to end so I will be better able to take my leave."

"Hang on, so you're not planning on mating?"

"No."

"Why not?"

"Tradition. I must refrain from sexual activity until I reach one thousand years of age."

"Some of these guys look much younger than you."

"None of them have my status."

"You're weird."

A female, shorter than average and not as slender, started to slowly and cautiously approach Sesshoumaru. Her eyes widen slightly when he growled, but otherwise, she was not deterred. She inched closer. Sesshoumaru snarled as she placed her hands on his bare chest (captured during a bath, remember?) causing her to flinch, and continue her progress.

"My Lord Sesshoumaru… y-you probably don't remember me, I'm…"

"I know who you are." Sesshoumaru's back was pressed flat against the stake. His pulse had quickened considerably, and his breath was starting to follow his heartbeat's example. His entire body was tense, and he seemed to by trying to back up in spite of the stake holding him in place. "And I suggest you find a new target."

"But… I just… that is…" She was leaning in, now pressed against his chest, her lips coming dangerously close to his skin.

The stake supporting him finally gave out, and he fell backwards on to his back, startling the young female tempting him. He jumped from his position on the ground into the air, and attempted to fly off. Unfortunately for him, he didn't get far.

In less time than it takes to blink, nearly every female in the clearing had pounced on him, and dragged him back to the ground, where they put four smaller stakes in the ground, and used them to tie ropes to his wrists and ankles. He now had his hakama back in place (though how that had happened was beyond Inu Yasha), and was pinned to the floor on his back, arms and legs spread. The female who originally attacked him in the clearing leaned over him.

"Lord Sesshoumaru, no female in this clearing would ever force herself on anyone, but that doesn't mean we're going to let you flee temptation. If you remain a virgin through this season, it will only be through sheer determination." Sesshoumaru growled, and the formidable female just smiled. "I recommend getting comfortable. You're going to be there for a while." And with that, she walked off. As soon as she left Inu Yasha attempted to struggle free, but to no avail. Half-demon or not, the heat had begun to affect him.

…………………..

Inu Yasha felt sorry for his older brother, for the first time in his life. It had been a few hours since Sesshoumaru had been pinned to the ground, and it seemed that the females were taking his seduction in shifts. At any given moment, he had at least three females attempting to break his resolve. At the moment, there was one kneeling patiently between his thighs, with her elbows on either side of his waist, staring up at him, one tracing lazy patterns on his chest, and the other leaning over him, with her hair cascading around their faces doing who knows what. And then it happened.

Sesshoumaru's body went rigid, and his left hand twirled, releasing his light whip, which coiled itself around the neck of one of the temptresses on duty. She had, a moment before, been tracing lazy patterns on his chest, but her hand had proceeded to migrate lower, and lower, until she found herself in restricted territory with a light whip hovering so close to her neck she didn't dare move. She was very tense, and lifted her hands up near her shoulders in a gesture that expressed physically what her soft whimpering expressed verbally. Seemingly satisfied, Sesshoumaru relaxed slightly, and the whip disappeared. He started to growl when she tried to put her hand on his chest again. Taking the hint, she walked off. Another female rose, clearly about to take her place, but the woman between his legs gestured for her to stay there.

"Sesshoumaru? How long does this season last?" The hair of one of Sesshoumaru's temptresses blocked Inu Yasha's view, so he didn't see him sigh for the first time in years.

"Too long."

"How long?"

"One moon cycle."

"What! I have to get out of here, there's no way I'll last that long!" Several females rushed over to try and claim him, but Sesshoumaru barked once, and everyone froze. The woman under his head lifted her hair out of the way.

"Stop. I will personally burn away the reproductive organs of the first fertile female to touch him." Sesshoumaru said calmly. All the young females pulled back, but a few rather old looking females looked to Sesshoumaru with pleading stares.

"None of you can reproduce, correct?" There were gleeful nods and an assortment of giggling in response. "Very well. Do not damage him, I intend to battle him when the season ends."

"Oh, thank you Lord Sesshoumaru!" They pounced.

"Sesshoumaru, you bastard!" They had untied his hands and rolled him onto his back, pinning him in place. Sesshoumaru shook with the effort not to laugh. Once he had himself under control, he said simply,

"The older females often help the younger women with particularly stubborn males. It was either you or I."

"Don't think we've given up on you yet, Milord." Said one particularly feisty old inu, her voice muffled by a mouthful of Inu Yasha's neck as another demon tied his wrists together, and tied the rope to a stake one of her companions had just driven into the dirt. Inu Yasha growled but the old bitch ignored him.

"I think you will find we are not as easily intimidated as those minxes are."

………………………..

"Lord Sesshoumaru…" a soft female voice nearly purred. Inu Yasha opened his eyes, and looked around. The four older demons who had adopted him as their new play thing were fast asleep, each cuddling up against a different portion of his body. They really weren't so bad when they weren't trying to devour him… and were unconscious. Being unconscious did wonders for their personality, Inu Yasha decided.

"Please, milord… help me… make it stop…" Inu Yasha looked over to the source of the voice. It was that first, short inu that had approached Sesshoumaru earlier. She was now kneeling next to him, running her fingers lightly over his chest. Sesshoumaru's eyes were closed, but his breathing was much too quick and erratic for him to be sleeping. He tossed his head from one side to the other from time to time, but he didn't speak. Little did Inu Yasha know, he didn't trust himself to.

"That's a cheap trick, lady, attacking him when he should be sleeping. You'll never win him over with a cheap stunt like that, he'll refuse you out of pride."

"O-h, you're right… It's not right… I'll… I'll let you sleep, you must be tired after a day like that I'll… I'll go I guess…"

"Yeah, you do that." One of the older women started to stir. "Relax, I'm still tied up, I'm not going anywhere." She snuggled closer to his abdomen, which she had been using as a pillow, and went back to sleep.

What Inu Yasha heard next was so quiet for the rest of his life he would always wonder if he had really heard it or not. It was so, out of character that he had to have been imaging it. But what Inu Yasha could have sworn he had heard was the softest of whispers from his brother, saying "thank you".

…………………….

"You wish. As if I would ever have need to thank a half-breed like you."

"Yeah, well see if I ever help you again you ungrateful dog!"

"You're 'help' was not necessary."

"No, that was a stick in your lap, not an obvious sign of arousal."

Sesshoumaru growled, his eyes turning red. The ropes around his wrists and ankles broke as he sped into the air in a ball of light, and in his place stood one magnificent inu… soon to be joined by several slightly smaller inu. There were seven in total, and they were all pushing up against him while trying to push each other out of the way. One particularly aggressive female managed to slip underneath him, bringing his front paws off of the ground and rubbing against him in a very suggestive manner. Sesshoumaru growled possessively, but shook his head and returned to his humanoid form. The females joined him.

"Damn. I was so close!" Said one tall, thickly build female.

"I know. I felt sure you had him." Said another, smaller female.

Sesshoumaru lay down and stretched his arms and legs out so the females could tie him up.

"You- you're letting us tie you up!" Said the same short, curvy female that had manipulated him last night.

"I would not have escaped, this season has affected me more strongly this year than most."

"Probably because you've been waiting so long. And it has been a long time, hasn't it? Since you first matured? All those years of waiting it out, of denying your instincts…" Her hand trailed lazily from his cheek to his neck. "Suppressing your desires… It must be so… frustrating…" Her hands slid onto his shoulders, which she started to rub sensually, if a little awkwardly given that he was laying on his back. She was leaning over him, and slowly started to lean in closer, inching her lips towards his. "I… Milord… if it's not… out of line… could I… maybe… possibly …" At the last possible moment Sesshoumaru shook his head to clear it, and proceeded to growl menacingly until she went away.

"Who is she?" Sesshoumaru didn't answer. "Sesshoumaru, come on, you might as well talk, we're gonna be here a while."

"I do not need to talk. I am perfectly comfortable with silence."

"Fine!" Inu Yasha was fine… for about two and a half seconds. Then he began to fidget. His leg twitched, his ears flattened and rose, and flattened and rise, and he bit his lower lip and blinked and blinked andblinkedandblinkedandblinkedand-

"Enough, Inu Yasha." Inu Yasha stopped. Then started up again. Sesshoumaru smirked. "Have it your way, Little Brother. Setsu!" Setsu, the old bitch that spent the night using Inu Yasha's abdomen as a pillow, came forward and bowed.

"Milord?"

"Inu Yasha desires company."

"Yes, Milord!" She said happily. She then pounced on Inu Yasha, straddling his hips and happily nuzzling him under his chin.

"I'm fine, honest, you can stop!"

"Can, but won't!" She said gleefully. Inu Yasha decided this was going to be a long day.

…………………….

"Hey, Setsu? How come no one was screaming like that yesterday or the day before?" Inu Yasha was seriously considering swearing off mating. Forever. Anything that could make a warrior cry out like that had to be painful, and he had been hearing it all day.

"Hmn?" she asked groggily from her position from Inu Yasha's stomach. The other three had grown bored with him but she felt he made an excellent pillow for her early morning, mid morning, noon, afternoon, and evening naps, as well as her nightly rest.

"Why are so many people moaning and screaming today when it was so quiet yesterday and the day before?"

"Oh, that." She yawned. "There's an old legend about it somewhere, but it's long and I've forgotten most of it. Basically, because of the legend, as a tradition no one actually procreates until the dawn of the third day."

"So why were they all tormenting Sesshoumaru?"

"Certain families are excused because they are encouraged to reproduce as much as they can, to strengthen the bloodlines. Yours happens to be one of them."

"Oh. But Sesshoumaru said he's not supposed to reproduce until he's really old."

"One thousand is not old, it's young. Besides, that is a different tradition, established several millennia ago, back when the inu population was still large. Personally, I think he should follow his father's example and mate young, but it is not my decision to make."

"No, it isn't." Sesshoumaru stated, somewhat tense.

"I don't get it, if all the other males are allowed to mate now, and there are more males than females, why are there still females trying to get Sesshoumaru?"

"Instinct. They all want him. Hell, even we old ones want him. It wasn't so bad for him before Inu no Taisho died, because then everyone wanted him so badly that not bothering Sesshoumaru was easy. Of course, his mother made it clear early on that anyone who touched her mate would have her to answer to. It's actually quite funny. Sweetest creature you'd ever meet most of the year, but the second mating season hit, she was downright scary if you went near her husband. And they say males are territorial."

Suddenly, Sesshoumaru snared viciously, and every female within what would have been striking distance if he weren't tied down flinched and jumped away. Sesshoumaru laid there, pulling at his restraints, with lips parted and panting heavily. Every fertile female in the clearing seemed torn between pouncing and staying very still. One seemed to have gathered the courage to approach him. She lifted her foot ever so slightly and put it right back down at the sound of another ferocious snarl Sesshoumaru. And that's when Inu Yasha smelled the scent of the very last person he wanted to deal with right now.

"Naraku!"

…End Chapter…

I do not think this will be more than two chapters long, and the next chapter should be up by the end of the weekend. Please review, this was the first story like this that I've ever written and I really need feedback.
