Mates

For Iruka to take all that just transpired as calmly as he did was something Kakashi wasn't prepared for. He expected more of a reaction, maybe an outburst of anger or some inconsolable crying. He never expected for the teacher to be so still, nursing a cup of tea in his hands and nodding as Kakashi delved into an explanation about Naruto and Sasuke's relationship.

Occasionally the brunet would ask a few questions to clarify some things but he never stopped Kakashi. After the whole explanation about Sasuke and Naruto's relationship, his relationship with the foxes and how he wasn't human, Iruka only had one question to ask.

"Why aren't we mated yet?"

Now that was something Kakashi didn't know how to answer.

"I…"

Iruka stood up, his expression was dark and Kakashi felt a sense of danger. While trying to pacify his now enraged lover, there was little he could do except to back up… right into a wall.

"I-Iruka… please! I can explain…"

The teacher pinned the taller werewolf to the wall and grabbed him by the collar. "Shut up," he growled before kissing the alpha roughly.

Kakashi was floored. He didn't see this coming but it worked as well.

"I'm going to make him mine," the wolf thought and returned the kiss.

-End of Recap-

Never in Kakashi's wildest dreams did he imagine Iruka would flip their positions over and take the lead in bed. Yes, his dolphin could be really bossy about matters outside of the bedroom but Kakashi always thought it was cute. Right now, he was looking at a new side of the teacher and that assertiveness was hot as hell. How did he not know about this provocative side of his lover? How did Iruka keep this under wraps for so long? Thinking about it made him painfully hard as Iruka glared at him, pinning him down with his stare as he unzipped Kakashi's pants.

As the teacher forced the werewolf on his back and smacked his hands away, Kakashi could only be reduced to watching his lover manhandle his manhood. Kakashi swallowed hard when Iruka palmed his reaction threateningly. Kakashi wondered how it was possible that nobody had snatched away his mate yet. It took him so many years to finally met Iruka and damn, the wait was worth it. Umino Iruka was every definition of perfect in the alpha's eyes.

The teacher didn't seem too surprised when Kakashi told him about his true identity. He wasn't even surprised or disbelieving when Kakashi explained that the clan weren't humans. In fact, Iruka calmly took all of it in and only asked about some of the things he should be mindful of in future now that he knew their special circumstances. How could anyone be so perfect?

As Iruka took the tip in and hollowed his cheeks to suck hard, he tucked some stray strands of hair that had fallen over and closed his eyes, relaxing his throat to take all of Kakashi in. After Iruka expressed his desire to mate with his lover of close to three years now, Kakashi naturally couldn't hold back and the sight before him sent him over the edge faster than usual.

Iruka gagged a little but drank it all up and licked his lips. His eyes were hungry for more and Kakashi growled. Without needing to hide his aroused state or transformation, his inner wolf yearned for more. Despite coming once, Kakashi was still erect as he pulled the teacher into his lap to fiercely kiss him. Iruka's voice was raw and slightly hoarse form deep throating him earlier but Kakashi intended to make this songbird sing all night.

"Are you certain you want to form the mating bond today?" Kakashi asked one last time before he let his inner wolf take control.

Iruka groaned. Why was this wolf asking such a thing now? "Yes., I'm sure. Now hurry up and knot me. I trust that if my body gives out on me, you'll nurse me back to health after this."

Kakashi blushed and nodded before kissing the sweet teacher twice. He prepared Iruka as best as he could and felt the beast in him become more impatient with the marking ritual. The werewolf also couldn't hold his beast back and partially transformed under the influence of his emotions, startling Iruka slightly.

The mating pheromones released into the air made Iruka slightly light-headed and he unconsciously assumed a submissive position, ready to be knotted and marked. Kakashi's heart swelled with happiness when he saw that. Iruka parted his thighs and held them apart so that Kakashi could easily enter. The werewolf didn't wait any longer and hit the home run in one swift plunge.

Iruka gasped in both shock at how much wider he was being spread and with pleasure as the blunt head hit his prostate. Kakashi worked up a restless pace opting to growl into his ear or nip the shell of it while they rocked in tandem. Kakashi couldn't stop the unravelling of his transformation and before Iruka knew it, he was getting pounded into the mattress by a wolf-human hybrid.

Kakashi's teeth were now closer to a wolf's than a human's and his eyes had changed colour to something like molten gold. Iruka found himself mesmerised by the beast-like eyes but the furry appendages on his head hidden within the white spiky hair were what caught Iruka's attention the most. If not for the activities they were currently engaging in, he would have loved to run his hands over them to feel them twitch. Also, the bushy silver tail constantly twined itself with one of Iruka's legs, keeping him in place as Kakashi' grew larger inside of him.

The werewolf howled when approaching his climax and carried Iruka up effortlessly, sinking his teeth deeply into the teacher's shoulder until they could smell the coppery tang in the air. Iruka shuddered in the superhuman hold and trembled in pain as Kakashi filled him with his seed and swelled up painfully inside of him. He felt as if a fever had taken over him, confusing pain for pleasure as Iruka threw his head back and came hard. The pain in his lower abdomen didn't subside as Kakashi came over and over again inside of him as if trying to get him pregnant.

Iruka was slightly afraid of becoming the first man to be biologically pregnant with half-demon kids but Kakashi assured him that it wouldn't happen this round even if it was possible. Tonight, Iruka would abandon his human self to join Kakashi as a converted supernatural being. The mating ritual was more than just a wedding ceremony for werewolves. It was something that tied both individuals together in soul, spirit and life. Should something happen to one of them, the other wouldn't escape unscathed.

Iruka was touched that Kakashi trusted him and loved him this much to want to share everything with him. coincidentally, he felt the same. There wasn't anything he wouldn't do for this overgrown pup. However, that was something Iruka wouldn't tell Kakashi in case his head gets too inflated with an ego that it would no longer fit through their door.

After the intense lovemaking, Kakashi cuddled with Iruka and waited for the pressure of the knot to ease. He could tell that changes were already happening to Iruka's body as the mating mark healed rapidly before his eyes. He could also smell the changes to his mate's scent.

Iruka was fast asleep and boiling hot, his human body fighting against the changes but Kakashi knew that by morning all that would change. Iruka would truly be one of them with the same kind of supernatural abilities from high-speed regeneration to keener senses even if he couldn't use magic or transform.

Kakashi nuzzled his mate and held him previously in his arms that night, happy that they were finally one.
