Title: Love of a Lifetime

Disclaimer: I don't own Harry Potter or Inuyasha. They belong to those that created them.

Warnings: This is a crossover and is very AU. The Seventh book did happened, but Severus Snape wasn't killed he survived the bite. The Epilogue also didn't happen. There will be mistakes because I don't have a beta and this is a slash/yaoi fic.

Author's Note: I received a review about how Inuyasha could have met Sirius twenty years ago when he was stuck to the tree. I didn't say Sirius met Inuyasha then only during those twenty years. More will be explained in this chapter and I hope it will clear this up for you. Things get wild from here on out people so you've been warned.

Chapter Seven:

"Bloody hell!" Severus never knew being in heat would be this bad. His whole body felt like it was in pain and he was so hot. Inuyasha and Kouga were in the same shape he was if not in more pain. Severus was afraid to use any pain potion not knowing how it would react with the heat and the last thing he wanted was to make it worst. Kouga had arrived only a few hours before with several lesser demons following behind him. They wanted to mate with new young omega lucky for him Sesshoumaru was already at the cottage wanting Severus. The Western Lord was able to kill the demons with Mitsuya's help and give Severus enough time to allow Kouga into the cottage without Sesshoumaru following. Of course, Sesshoumaru was beyond angry because he lost his chance at getting the Topaz demon. Severus stood by the window watching Sesshoumaru growl in anger with Black laughing at his pain. It was a shock that the other Topaz omega was still alive after laughing at the Lord of the West. Then again Black has always been a lucky bastard when it counts if you don't count the time he ended up in Azkaban.

"I don't want to be an omega." Kouga whimpered as he laid on ground his arms wrapped around his legs. Inuyasha was hugging the wolf from behind trying to offer him and himself some comfort from the pain. Inuyasha might not like Kouga, but the wolf was still a friend and he wanted the comfort too. Severus refused to show that he was in any pain. He was a Snape and wasn't about to let anyone know he was weak. "How can you guys stand the pain?"

"This is our first heat too Kouga and we do feel the pain. Snape is just hiding it well, but make no mistake he's suffering like we are." Inuyasha hugged the wolf close trying his best to ignore his own pain. He couldn't understand how Snape was still standing looking out the window where Sesshoumaru was standing outside of his wards. He wondered why Katsuya wasn't here trying to get to Inuyasha. The older wolf kept on telling Inuyasha how he was going to take the hanyou as his mate and yet he hasn't seen him all day. "Katsuya isn't here its only Sesshoumaru waiting outside."

Kouga turned around nuzzling his nose into Inuyasha's neck. The hanyou's scent offered him comfort calming him down. "My father said he had something to do, but I'm sure he'll be here soon." Kouga knew his father wanted Inuyasha so there was no way he would miss tonight. "I'm sure he's out looking for a mate for me."

"It makes sense." Severus sat down next to the other demons not able to stand the pain any longer. A part of him wanted to let the wards fall and allow the Western Land to come to him, but he wouldn't give in not just yet. "Sesshoumaru's wants me and Katsuya plans on taking you Inuyasha. It makes sense that Katsuya would find a mate for Kouga to make sure he's taking care of."

Kouga grunted not liking the idea of some demon having control over him. He has been Alpha since his birth and now an omega. The thought of another male being in control of him wasn't easy to handle in his mind. "I hope he isn't an asshole."

"I wouldn't bet on it if I were you, not if your luck is anything like mine." Inuyasha leaned back when Snape settled at his side. He knew the other demon was in a lot of pain and no matter how well he tried to hide it he needed comfort like the rest of them. "Hell look at Snape he's going to be mated to my brother and we all know what an ass Sesshoumaru is."

"True Sesshoumaru is an ass and seems like he has nothing more then ice in his veins." Kouga leaned up and looked over Inuyasha's shoulder to the black haired dog demon. "I think both of you would be a good couple since you're as much an ass as Sesshoumaru is."

Severus glared at the stupid wolf demon hoping he would shut up. "Yes, and I'm sure your father would find the ugliest demon he could find to be your mate."

"My father doesn't hate me that much." Kouga smirked and then he laid back down next to Inuyasha. "Either way all three of us will be mated before tomorrow night. We can try and fight the heat, but we will lose." Kouga has seen enough matings to know what will happen.

"Yeah I know doesn't mean we have to like it." Inuyasha like Kouga knew they would be mated before tomorrow night. They could fight all they liked, but you can't win against nature.

Severus snarled not liking the idea of being mated to anyone. Within a week, either Sesshoumaru would kill him or the other way around. They were both too stubborn for their own good. Severus had been in the control of someone else all of his life. First, it was his father and then Voldemort and when he wanted to leave the Dark Lord, he was taken in the control of Dumbledore. True the Headmaster was kind and acted more like a father to him then a Master however, it didn't change the fact that Severus was still in his control. Severus wanted to have control of his own life and even now, it seemed like it wasn't going to happen. However, this time he wasn't going to give up his freedom without a fight. "We can fight this heat we don't have to mate against our wills."

"You don't understand anything Snape." Inuyasha grew angry not knowing why Snape couldn't give in and accept his fate. "There is no winning against this no matter how fucking stubborn you are. You can't fight nature and soon you will be the mate of Sesshoumaru and me the mate of Katsuya. The heat will get so bad that we will throw ourselves at them." Inuyasha might not like the thought and like he said before you can't win against nature.

"I've seen females and omegas in heat and they always give in to the heat in the end." Kouga didn't mention how the Alphas would fight for the right to mate an omega knowing it would piss Snape off even more. He decided to let the dog demon believe what he wanted. Snape would learn the truth soon enough.

"How about we try and get some sleep?" Inuyasha knew they needed some sleep before their heat got worst. He knew the pain wasn't anything now and it was going to get a lot worst before the night was over with."

Kouga and Snape nodded snuggling closer to the hanyou and settled down for the night. They would worry about everything else tomorrow for now they will forget.

Katsuya was pissed all to hell as Toga and Hayato followed behind him making their way to Inuyasha's forest. He knew Inuyasha was already in his heat and prayed to Kami that he was able to make it to Snape's cottage and Kouga as well not wanting his son to become the mate of someone he doesn't approve. Katsuya knew his son became an omega without any help thanks to Ginta's report. At least Toga didn't have to force it on Kouga and for that Katsuya was grateful. Kouga becoming an omega on his own proved his point that his son was always meant to be an omega. Katsuya even found the prefect mate for his son knowing Hayato would protect his son and keep him out of trouble. Hayato was Katsuya's General and Kouga's teacher when he was younger. Hayato was also the older brother of Ayame of the white wolves and Katsuya would hate to be in the cave when she found out her brother got the wolf she wanted. Oh well Hayato can handle himself and he would be able to handle his sister.

"Dammit Katsuya I did say I was sorry." Toga growled it wasn't his fault that his body took so long to regenerate. They still had plenty of time to make it to Inuyasha and it wasn't like Katsuya had to wait for him. He could have gone off on his own and Toga would have caught up. "Inuyasha is safe and I'm sure he's waiting for you to join him."

"I doubt that Toga-sama." Hayato smiled having heard some stories about the hanyou. He would give Katsuya hell and Hayato knew it was going to be entertaining to watch. Of course he was going to have his own problems with Kouga and his sister. "From what I learned Inuyasha isn't someone to mess with and I'm sure Katsuya-sama he will not allow you to mate him without a fight."

"My sons are no pushovers." Toga grinned at his old friend as they entered the forest. "I know you will take good care of my youngest, Katsuya."

"You don't even have to ask, Toga." Katsuya left the dog demon behind as he ran towards the cottage with Hayato right behind him. Toga would catch up soon of that he had no doubt.

When Katsuya and Hayato arrived at the cottage and found Sesshoumaru standing at the edge with a barrier in front of him. Mitsuya was leaning against a tree with his mate in his lap snuggled against him for warmth, Hayato joined Sesshoumaru at the edge of the barrier. "I see your still keeping control of yourself?"

"I will not lose control over myself wolf." Sesshoumaru said not once taking his eyes off of the cottage in front of him. "Snape will be the first to give in to me. Are you here for Katsuya's son?"

"Yes, Katsuya gave me his permission to mate with Kouga." Hayato grinned, he had always wanted to the young wolf Prince. Sure Ayame was going to give him problems, but there was nothing she could do since Kouga was now an omega and an omega couldn't mate with a female. "And guess who I've met on the way here?"

If Sesshoumaru could he would have smirked by now, but he couldn't ruin his reputation. "My father has finally healed his body and returned to the land of the living."

"You have always been too smart for your own good, Sesshoumaru." Toga appeared next to his son. He knew Sesshoumaru wouldn't be surprised when he returned alive. Inuyasha was another story because his youngest son didn't know about the souls of demons and how they couldn't be destroyed and if the body was still intact they could return to life. "I've heard from Katsuya that you found a Topaz omega you want to mate with?"

"Yes, his name is Severus Snape and he is different from any other omega." Sesshoumaru told his father everything he knew about the Topaz dog demon. He knew he chose a good mate and his father would think the same thing.

Toga grinned when his son finished talking. Sesshoumaru had indeed picked a demon worthy of being the mate of a Western Lord. Severus Snape sounded hard to handle, but that was a good thing. At least his son wasn't going to be bored anytime soon. "You have chosen well my son."

"You say that now wait until you meet the demon." Sirius had over heard Sesshoumaru and his father talking with each other and had to say something. "Snape isn't a good demon and he isn't evil either. I guess you can say Snape is more in the grey area and he isn't a fool. I respect the demon, but I don't like Snape and I might never will and I will say this much you are going to have your hands full with dealing with him."

Mitsuya chucked and pulled Sirius closer to his body. "You are no different my love."

Sesshoumaru would have snorted if he could. "I can assure you father that Mitsuya's mate is a lot worst then Snape. At least the other topaz knows when to shut up."

"You are a prat Sesshoumaru-sama." Sirius spat out while hating the Western Lord. He hated the fact that his mate respected the demon so much. "You should be glad that I say around to put up with your crap."

"Enough my mate." Mitsuya warned his mate making him quiet. Sirius has always had a temper and he loved to play pranks on others with Sesshoumaru being his favorite target. Of course Sirius stopped knowing Sesshoumaru was getting annoyed and an annoyed Sesshoumaru was a very dangerous creature. Perhaps having Snape in the place will give Mitsuya's mate someone to talk to and even if they weren't friends at least he could hope they would keep each other out of trouble. "Sleep for now because tomorrow is going to be a long day."

"We should rest Sesshoumaru." Toga told his son as he went to the one of the trees sitting down and leaning against it. He would never admit it out loud, but his body was tired and it needed rest. "There is nothing you can do for tonight."

"Toga is right Sesshoumaru." Katsuya sat next to Hayato a smirk on his face as he thought about tomorrow. "I say by tomorrow night the heat will be bad enough that our chosen will give themselves to us."

Sesshoumaru didn't believe the Topaz was going to give up so easily. Snape was going to put up a fight and Sesshoumaru couldn't wait. Having the stubborn demon as his mate was going to be fun. At least his life wasn't going to be boring.
