Yay, amazing, a new chapter!

It had been late in the evening when Yamato had returned to the village after an ANBU mission with a few other nin. He had barely gotten into the ANBU headquarters when he saw people standing around with drinks in hand, laughing and joking. He had no idea what they were celebrating, but he could go for a drink. The mission had been a rough one.

"Hey, Yamato!" He had to stop himself from sighing loudly as Genma approached him. While he had nothing but respect for the other man, sometimes his high energy was more than Yamato could handle, in particularly when he was tired.

"Have you heard the great news about your precious Kakashi-senpai, hmm?" Blinking in confusion at the man now hugging his waist a bit too familiar, he wasn't sure what the man was talking about.

"What news?" The smirk on the honey haired man made him lean his head to the side in curiosity.

Genma leaned in and put his mouth right by Yamato's ear, once again being a bit too close for Yamato's liking.

"Our man Kakashi has bonded with an omega. Rumor has it they have a child on the way too."

Yamato almost felt ice going down his spine, and yet in his mind he was still happy for his friend and teacher.

Naturally, since Kakashi was an alpha, he had always known the man would find some nice lady to settle down with eventually, and as a prodigy it was a given he would have kids one day. He had just hoped it would be later on. That their time as teacher and follower would continue one way or the other as it had all these years, even since before he had known about their sub-genders.

His sub-gender...he had been born an omega, but during Orochimaru's experiments the man had injected him with gene altering substances. One part of it was to make him a wood technique user, but since wood techniques could only be used by alphas, he had even gone so far as to change Yamato's genetic structure for his sub-gender.

During his medical exams in his teen years many years later Yamato had gotten the test result "unknown" back. Basically he was both alpha and omega, in some un-natural state between the two spectrum. Being born an omega could be difficult enough, but to be the only known altered omega, that was hard.

During his teen years he had waited for his omega heat, even hoping that he and Kakashi would be able to bond when he got it, but the years went by without it showing up, and before he knew it they were already adult. It had taken many years before he had come to accept that his heat wouldn't come, that his body was just too fucked up to function that way. Even though he was in part alpha he didn't respond to omega's in heat either, so his chance of bonding with an omega was low as well.

Naturally he could still find a nice beta to settle down with, and in a way he should be grateful not to be enslaved by the heat cycles like omegas and alphas...and yet he felt strangely jealous.

"Hey, did you get a stroke or something?" He blinked and focused on the man next to him, snapping out of his deep thoughts.

"Sorry, it was just a bit shocking to hear the news...well not shocking, but it's a bit much to take in, I guess." He mumbled and focused on the floor in front of them.

This feeling...was it really jealousy? Yes, it probably was. The question was if he was jealous for the omega that had bonded with Kakashi, or if he was jealous for Kakashi having bonded with an omega, or maybe just jealous that his friend was moving on in life without him being part of it.

Genma patted him on the back and mumbled something about him being a 'poor soul' and proceeded to shove a drink into his hands.

He stared at the green liquid in the cup in suspicion, but then almost on impulse chugged the whole thing, nearly choking on it.

"Whoa. You need to be careful with that stuff, it's ANBU home-brew. You don't chug ANBU home-brew, not if you want to live tomorrow, 'yah know."

Yamato snorted. Now the man tells him. Already feeling the fog starting to take hold as the chakra infused drink slammed into his system, he shoved the cup back at Genma.

"I need another one."

They looked at each other for a few seconds, and then Genma just grinned. The rest of the night was somewhat blurry for the wood using ninja. He did remember way too many drinks ending up in his hands, and the cup he held being empty way too many times. He also did remember that someone was saying that people had been visiting Kakashi and bringing him gifts all evening. In his fogged mind something made sense about that.

"Yeah we should...you know, we should totally do that."

Various voices of agreement was heard, and then maybe the worse idea in the history of bad ideas made by drunk ANBU was made. Drunk off their asses or not, they were going to visit Kakashi and congratulate him on his new mate.

They had arrived at the house just after two in the middle of the night, not that they were sober enough to understand what time it was, or that the time wasn't really right to drop by someone's house. Being ANBU, even drunk of their ass ANBU, Yamato and the three others that had come with him were been able to enter Kakashi's house way to easily. Yamato stood in the middle of the living room, swaying gently with a cup in his hands. On the table in the living room he could see a bunch of gifts, and he remembered that yes, they were here to celebrate Kakashi.

The other three with him, Genma, Kotetsu and Izumo, also looked around in slight confusion.

"Ah, I guess he's gone to bed already."

Now, normally at this point they would have left. If they hadn't been drunk on ANBU home-brew, leaving would have been the obvious thing to do. Now instead all three of them casually walked up the stairs towards the bedroom, Yamato going first since the others had no clue on the layout of this house. Yamato however had been in this house countless times since he was a child, and thinking that Kakashi might be in his bedroom, his feet automatically carried him there with the other three close behind.

He had almost fully opened the door to the bedroom before he realized his mistake in doing so, and once it was open he just stood there, not knowing how to respond. In front of his eyes Kakashi and Iruka was kissing and removing items of clothing. The air was thick with pheromones. Even if the two had bonded, there was no mistaking an alpha in heat. For a few moments his brain struggled with the image of a male under Kakashi, wondering where Kakashi's new mate was at, before he realized that Iruka was the omega who had become the silver haired nin's mate.

He could hear a small thud next to him, and looking over he could see Izumo being flustered and panting, holding a hand over his chest, leaning against the wall.

In the back of his alcohol infused mind Yamato seemed to remember that Izumo was an omega. While a bonded omega wouldn't attract any more alphas by their scent, an alpha could have any number of omegas bonded to them, and the smell of their rut would be very hard to resist for other un-bonded omegas.

Izumo wasn't bonded with any alpha, which meant that... Ah yes, there it was. Kotetsu had the other man shoved against the wall in a matter of seconds, kissing Izumo hard. Yamato's gaze kept wandering between Kakashi and Iruka, who were now completely naked, and Izumo and Kotetsu, who were making out madly a few meters away.

A pair of strong hands sneaked around his body, stroking his chest under his shirt and stroking his swelling cock through his pants. Feeling Genma's breath against his neck, he shivered as the man started licking the side of his neck, just under his ear.

"Kakashi, please, please..." Yamato watched as Iruka was begging while Kakashi was fingering him hard. He could feel his own cock twitch at the sound of Iruka's pleading and needy voice and the wet sound of Kakashi finger fucking the man.

"Say it, Iruka, say it out loud." Kakashi's voice was so husky, Yamato was certain he had never heard it like that before. Behind him he could feel Genma move a little bit, and when his hands returned they were undoing Yamato's pants. This was so wrong. He knew that maybe he should try and stop this, but if he spoke or made any sudden movements then his friend, his hero, his teacher might look up and see him, and he didn't want that either.

"Please...come inside, please...fill me with your...semen, please, Kakashi..."

Yamato sucked air through his teeth when he heard the plea. He could feel Genma stroke him through his underwear and he had to lean against the door frame for balance, arousal and alcohol making it hard for him to keep himself upright otherwise. He could feel Genma's hand stroking between his butt cheeks, and to his amazement he was aroused and wet back there, it was the first time he had ever become aroused like this.

Looking to his side he could see that Izumo and Kotetsu had wasted no time, Kotetsu was already pushing his swollen cock into Izumo, and Izumo holding one of his hands tightly over his own mouth to try and keep himself from making too much noise and giving them away. The smell they were giving off was amazing, it was so strong, and when Genma pushed down Yamato's underwear, he too placed a hand over his mouth and hoped that Kakashi was too distracted by his mate to notice them.

At that moment, Kakashi let his head roll back slightly, looking down greedily on his omega.

"As you wish, my love." And the silver haired nin, Yamato's hero and friend, sunk his cock deep into his needy partner. Genma mimicked the movement, and let his cock slide into Yamato.

As Genma sunk in deeply into Yamato's body, inside the bedroom Kakashi grabbed Iruka's legs and pushed them forward, and when he had adjusted his position and started thrusting, he turned his head to the side, ever so slightly, and made eye contact with Yamato.

For a second, Yamato expected the worst, but then Kakashi smirked at him, and started to thrust madly into his mate.

Behind him, Genma changed their position slightly, placing himself closer to Yamato, getting a deeper angle, making Yamato cling to the door frame for dear life, the thrusts of Genma closely mimicking the ones of the silver haired nin.

Maybe it was the alcohol, maybe it was the heat, maybe it was all things combined, but Yamato allowed himself to fantasize. He allowed himself to imagine that he was the one being fucked by Kakashi. Biting into his own hand to keep himself from making noise, he let out all pent up fantasies he had dreamt about over the years.

"Iruka, I'm close, so close..." If the panting against his neck and the sweat covering Kotetsu's face was anything to go by, Kakashi wasn't the only one getting close. Genma was thrusting hard now, his cock hitting so many good spots inside of Yamato that he couldn't help but to push back, to try and help the man get even deeper into him.

"Fuck, you smell so good, you smell so good. I'm so close, I'm going to fill you with my cum, with my child. Iruka, I'm going to get you pregnant."

Yamato's eyes rolled back and he could feel himself tensing up. Hearing Kakashi speak those words in that raspy voice sent him over the edge, even if they weren't directed at him, he had waited since his teen years to hear the man speak them. One of Genma's hands came up and helped cover his mouth to dampen the sounds of the moans he no longer could hold back, and just barely could he sense a bite over his shoulder as the man behind him tensed up as well, pushing in deep, forcing his knot securely into Yamato's body as the hard cock started to pump him full with cum.

Yamato panted hard through his nose, his fingernails digging into the wood of the door frame as his body received it's first ever load of cum deep inside.

It took them several minutes to catch their breath, and Genma was lazily licking the side of Yamato's neck, biting his ear gently, and then licked his neck again, his skillful hands now stroking all over Yamato's body once more. When they had calmed down a little more, Genma shifted them, so that they could move over closer to Izumo and Kotetsu. The last thing Yamato saw of Kakashi was the man still thrusting into his mate, completely lost in pleasure, and his own cup of anbu homebrew on the floor by the door, only then realizing he must have dropped it.

Genma got them close enough to Kotetsu and Izumo, both huddled against the wall on the floor, with Kotestsu still balls deep in Izumo, so that he could wrap his arm under both of their arms, and teleport them all away from the hallway of the copy nin.

They landed on a bed, where that bed was located Yamato wasn't sure, but still high on the home brew and the induced heat he didn't really care. He landed on his belly, and Genma, still bond to him by the knot, over his back, pushing the knot in deep. Yamato gasped and felt his body twitch at the feeling. It was his first time having a knot inside of him, in fact, this was the closest he had been to a real omega heat thus far in his life.

Next to him Izumo and Kotetsu started to make out again, laying face to face with each other.

Yamato laid there on the bed watching them, still pretty drunk. He could feel Genma shift so that the man was no longer putting his weight over Yamato, and it instantly became more comfortable.

They all stripped of their tops and gear, helping out where it was hard to reach. However, because Izumo, and partially also Yamato, had gone into heat they were far from done with each other.

While he was convinced that he would have been uncomfortable in this situation during any other circumstance, right now Yamato was deliriously relaxed. He and Izumo started kissing and touching each other, and looking back over his shoulder he could see Kotetsu and Genma making out as well. Seeing two alphas in rut and making out with each other was way beyond hot.

Genma, even though he was still aroused, was soon able to free his knot from Yamato, who shivered as he felt a steady flow of cum flowing out from his body. Kotetsu was able to free himself from his bond to Izumo shortly after, both alphas flopping down tiredly on the bed.

Yamato however, was not tired, not yet. He crawled over Kotetsu, and settled down by Izumo, and laid down next to him.

While the two alphas looked on with a great deal of interest, he started making out with Izumo again, and the man responded to him nicely. He clung to Yamato, and seemed to be pulling Yamato towards his own body, ever so inviting. Yamato felt himself responding, and climbing on top of Izumo, he let himself thrust against the omega under him.

By now Kotetsu was stroking his cock and watching closely, and being watched so intensely somehow spurred Yamato on. He let his cock slide back and forth over Izumo's cleft, feeling the cum flowing out from the omega.

He leaned back slightly, and watched in amazement as his cock became covered in cum. Izumo was biting his lip, and spreading his legs wide, he reached down and grabbed Yamato's cock, and guided it straight for his hole.

Yamato held his breath as the smaller male pulled him in using legs around his waist. He could feel himself sliding into the warm and wet channel. He groaned, and leaning down for a kiss he started to thrust. It felt so good inside, so hot and wet, it was making his head fuzzy all over again.

He could feel someone stroking and licking their way up his back, and a few moments later he could feel someone lining up with his body from behind. He moaned loudly, and seeing that Genma was on the bed on his left, he realized that it was Kotetsu that was starting to push into him, entering his body.

He groaned with excitement and stilled his body so that the other male could settle in deep inside of him.

Being filled by his second alpha that evening, and filling up an omega in heat under him, he couldn't understand why he hadn't done any of this sooner in life. Every part of his broken and altered instincts were being sated at once, and he could feel some kind of greed awaken inside of him.

He wanted more, oh so much more.

Thrusting deeply into Izumo, holding the mans hips down to get even more friction, and feeling Kotetsu starting to really pound away at him from behind, Yamato almost lost his mind to the overwhelming pleasure.

TBC - hope you all liked it.
