Author's Note: Hello, it's me C-Chan2 aka Neptunesdemon. You know, I've always wanted to delve into the world of mpreg fanfiction and after much lurking on a mailing list, I've decided to write one of my own. Lo and behold, I give you my first ever mpreg. I'm using the fandom Inuyasha for various reasons, the main being that I've always wanted to write one for this fandom. I'll apologize in advance; it has been a while since I've watched Inuyasha, so I really don't remember quite what happened. I wouldn't mind if you guys helped me out by correcting me and all that. That as well as the characters; I'll do my best to keep them in character, as I know how much it irks folk to have a Sesshomaru who is nothing like himself. Yes well, enough rambling, I'll let you go on and read the first chapter. Until the end of it, then.


Inuyasha sighed in irritation as he wiped sweat off of his brow, his feet dragging as he made his way down the forest path. He was uncomfortable, no doubt about it, and he knew damn well why. He could feel the others looking at him in concern, but he didn't have the patience to even confront them. Besides, it was too damn hot.

"Feh! Damn mating season!"

It was the worst time of year, especially since he had gone into his first heat last spring. Well, females went into heat, so you could say his body finally had the unavoidable urges to mate. It was the most embarrassing spring he'd ever known. He was able to scent every female demon there was in a 5 mile radius, and his body couldn't reach them all.

And that brought on the humping. His face turned red as he remembered the awkward mornings waking up with his groin grinding against his bed roll. And poor Miroku; after waking up to the inu-hanyou humping his leg, he made sure to set his bedroll as far away from the dog-eared demon as he was able. The perverted monk used it as an excuse to get to sleep closer to the women, stating that Inuyasha in his sex crazed fits was a danger to them.

"He's the danger." Inuyasha mumbled under his breath.

He breathed in so that he could sigh, but was only able to give out a painful whine as his groin began to yearn for contact. He could smell a fertile female nearby and she was so close it was making him insane.


Great, now Kagome was going to pester him.

"Is something wrong?"

He looked back at the reincarnation of Kikyo, his face obviously distressed and covered in sweat that had nothing to do with heat caused by the weather.

"I'm fine." He growled out, shifting in another direction different than the one the demon in heat was located. "Just stepped on a sharp rock."

"Aren't we heading south?" Miroku questioned, as the group stopped to watch the puppy-eared hanyou curiously.

"Yeah, well now we're heading west!" He snapped, not bothering to look back at them. "Who the hell asked you anyway?"

He was getting irritated, but he couldn't help himself. It was hard trying to ignore hundreds of youkai permeating pheromones that just screamed, "I'm ready and waiting". Damn it, he wanted to go looking but he had responsibilities. And then there was Kagome; what would she think of him if he just ran off like that? How would she protect herself? What if Kouga came and tried to take her as his mate like he was always boasting he would?

"Over my dead body!" He was screaming out loud, startling the group that had started to follow him again.

"Inuyasha! Just what is wrong with you!" Kagome demanded, her hands on her hips as she waited for his explanation.

"None of your damn business, wench!"

Damn it. He hadn't meant to say that.

"Sit boy!"

Inuyasha could only twitch in pain as he was reacquainted with the ground he'd come to know quite well since meeting Kagome. Why the hell couldn't she just take the damn beads off? She should know that he wasn't going to harm anyone by now.

He heard Shippo bounce over to him, and he would have swatted the kit away, but he was still mashed into the soil. The fox demon tentatively sniffed him, before his nose wrinkled a bit and his eyebrows rose. He whipped his head around to the others, before he was pointing down at Inuyasha, who was slowly starting to peel himself off of the ground.

"Inuyasha smells funny!" He announced, before cheerily adding, "He smells like he did when he was hugging Miroku's leg!"

Sango snorted, trying to hold in her laughter, Kagome covered her smile, but the monk blushed, trying to hide it behind a cough.

"Now, now, Shippo, no need to remind us of that little incident." Miroku told the kitsune, before he was looking at Inuyasha in contemplation. "Though it would seem that our friend has once again entered his yearly heat."

"I'm not a bitch, asshole!" Inuyasha snapped, teeth flashing. "Only bitches go into heat!"

"Inuyasha!" Kagome's voice was shrill with her disapproval.

"Well it's true!" Was the only thing the hanyou said in his defense.

"While that is indeed the term for which inu-youkai call their mothering females, I believe it is best, Inuyasha, if you avoid using it since it seems to upset Kagome." Sango suggested, with the monk and miko nodding in agreement.

"You shouldn't use such language around Shippo." Kagome told him.

"Well I-"

His words were stopped short as a scent he'd recognize anywhere hit his nose.

"Sesshomaru." He muttered.

He stood from the ground, his hand resting idly on the hilt of his sword as he turned to face the direction from which his brother was coming. Finally, something to take out his frustrations on. He was sure that his blasted brother was wandering closer for a fight, and with his body wanting to maim something since he really couldn't fuck someone, he was ready and willing.

"He's here?" He heard Miroku ask, the monk getting into a defensive stance.

Kagome was slowly reaching for her bow and Sango fingered her own weapon. Kirara was in full demon form, hunched down and waiting to attack, with Shippo cowering behind her.

Inuyasha sniffed the air again, and his eyes flashed red a moment as he grinned in delight.

"Yeah, that's him alright."

Him and what seemed to be a pregnant demon. It couldn't be that the cold bastard actually mated a female. Nah, it had to be a coincidence. Plenty of females around here in heat, one of them was bound to get knocked up.

Though as his brother drew closer so did the scent. It was a bit faded, but it was unmistakably there. Maybe Sesshomaru did find a mate. Which would be so unfair; why the hell did he get to mate while Inuyasha had to suffer?

"Damn lucky bastard."

The surrounding brush began to shiver as their expected, and yet uninvited, guest finally came closer. It took only a few seconds more before Sesshomaru was standing with them in the clearing. His cold eyes looked over each and every one of them before narrowing onto Inuyasha. The hanyou drew his sword, but held his ground, wanting his older brother to make the first move.

'Why the hell is he alone?' He wondered, looking past the proud youkai to see if he could catch a glimpse of this mystery woman. There was no one there, however, and he figured that she was hiding back in the cover of the trees.

A silence stretched out over them as they all stood there; ready to take action, but Sesshomaru never moved. He only stared at his brother, with cold amber eyes, and did nothing else. It was only a short while longer before Inuyasha grew impatient.

"You've got some nerve showing your face around here! What, you itching for a fight? I'll kick your ass if you want me to so badly."

Something like that would have usually gotten one of those cold and snarky replies from the older demon, but Sesshomaru didn't even bat his eyes at the words. Instead, he turned his back on the hanyou, walking back to the forest and saying over his shoulder, "Inuyasha, I wish to have a word with you."

Then he stopped, looking back to the group and daring them to follow.

"Alone." He announced, the threat in his voice quite evident.

He then disappeared back into the dense foliage.

The group stood there stunned, not really sure what to do. For that matter, they didn't really know what to think of it.

"That was odd." Miroku worded, standing his staff straight again.

"It would seem that Sesshomaru isn't his usual self today." Sango crossed her arms as she looked to Kagome.

The miko looked dumfounded.

"Yeah." She was agreeing. "That was weird. I wonder what he wants to talk to you about, Inuyasha."

"Feh! Bastard probably just wants to fight where no one can see." The hanyou ranted, returning Tetsusaiga to its hilt. "Doesn't want to embarrass himself when I kick his ass."

Folding his arms into the sleeves of his haori, Inuyasha started out after his brother at a leisurely pace.

"I'll be back." He told them as he left. "Just stay put until then."

The three humans, and two demons, watched as Inuyasha disappeared into the surrounding forest, all a little confused as to just what was happening.

"Is it just me, or does it seem as if something odd is going on with those two?" Miroku broke the silence.

Sango and Shippo nodded in agreement, and Kirara mewed her agreement as well. Kagome only sighed, before she was crossing her arms in a show of annoyance.

"So what else is new?" She spouted, the others only shrugging. "We might as well set up camp. It's almost dark and who knows when that idiot will be back."


When Inuyasha finally caught up to his brother, he realized that the scent of a pregnant youkai had become stronger. That could only mean that whatever bitch Sesshomaru was hiding had to be near by. Was this the talk that the bastard wanted? To flaunt his new girlfriend in front of him? His teeth clenched in aggravation, as the faint scent of unmated females taunted him even further, reminding him that he had yet to relieve himself from the strain of the mating season.

With is hand closing about the hilt of Tetsusaiga, Inuyasha braced himself for whatever it was Sesshomaru had prepared.

"Well what do you want?" He growled out, wanting his older brother to hear his displeasure. "If it's a fight, we might as well get to it. Though I don't know if you should risk getting your ass whooped. At least, not until your pretty little bitch isn't close enough to see her mate defeated. It'll save you the embarrassment."

He sniffed the air, his eyebrow arching as he watched Sesshomaru make the slightest of movements at the mention of a female. A grin broke out over the hanyou's face, and he folded both arms behind his head as he decided to tease the cold demon. If anything, it could lead to a fight, which he so desperately wanted. He didn't know if he could last waiting for Kouga to arrive. Besides, he always won when they fought, so it would be pretty boring.

"Didn't think you had it in you, let alone a dick that you knew how to use." He started, his golden-brown eyes watching the form in front of him tense. "Hell, the way you flaunt about like some kind of holier than thou asswipe, it was easy to guess that you'd find any bitch you come across to be unworthy for you to even fart on."

His eyes traveled to the only hand in his brother's possession, watching as it curled in anger for an instant, with his hopes rising that the youkai would turn and try to strike. However, he was disappointed to see his brother relax, and he figured it was best to push him some more.

"So, where is she anyway?" Inuyasha asked, looking about the trees and underbrush in search of her. "What? She so ugly you're embarrassed for her to show her mug? It's alright I won't laugh too hard. Must have been a dark night!"

Sesshomaru waited patiently as his brother laughed at his own horrendous banter, although every muscle in his body was ready to jump at the twittering half-breed and rip his throat out.

"I never thought I'd see the day you were stupid enough to knock up a bitch."

"There is no bi-" Sesshomaru caught himself before he began an argument with the bumbling idiot his father claimed to be his brother. "There is no female."

The hanyou stopped laughing for a bit, before he snorted, his arms folding into the sleeves of his haori again.

"Yeah, right. I can smell her and she's close by. Let's get this over with already so that I can get back to more important things."

"Listen, you sniveling idiot!" Sesshomaru hissed, his face still a cool mask though his voice was steady with aggravation. "Would you truly believe that this Sesshomaru would be stupid enough to breed just any female? Besides that, need I remind you that I am the last inu-youkai in existence."

He had obviously forgotten about Inuyasha, but the hanyou let it slide, him being a hanyou and all. He wasn't sure if half-breeds actually counted.

"Yeah, well, I've seen demons breed with others that aren't of the same kind. Who knows if you don't have some sort of cat fetish, or maybe-"

"Do not insult this Sesshomaru." Was the slow warning, and Inuyasha merely raised a brow at his older brother.

"So, there ain't no bitch?"

"Must I repeat myself?" Was the question in reply.

"Listen, I know she's here somewhere! I can smell her damn it!"

This was getting stupid. It was also getting old pretty quickly and Inuyasha was never known to be very patient. He didn't have time to deal with this. A pregnant bitch wasn't hard to miss and Inuyasha could recognize it as well as any other demon. If it wasn't coming from a female, like his brother was claiming, then just where the hell was it coming from?

He found his nose tilted into the air as he began to sniff around to see if he could find out in what direction she was being hidden. His head went from left to right, before it was centered in the middle again and he was staring right back at Sesshomaru, the silver-haired inukai having returned to wearing his impassive mask. The smell was strong on the older demon, almost as if it could be coming from him.

That's when something went off in Inuyasha's head, and his eyes opened wide in disbelief.

'No way!' He was screaming in his head, before he worded out loud, "You're the bitch."

Sesshomaru only rolled his eyes at his half-brother's stupidity, before his only hand lifted to rest over his silk covered abdomen.

"Inuyasha." He called for the hanyou's attention, before announcing, "I am with child."

'Well, shit.' Was all the hanyou could think.


I don't know what I'm doing here. It popped into my head and I've always wanted to try writing Inuyasha M-preg. I'm not sure what pairings will pop up yet, but who knows what will happen. I hope this was good so far, I don't remember much of Inuyasha and stopped watching it a while back. Well, leave your review and/or constructive criticism. I'd appreciate it.
