Few weeks later.

After the unsettling news the family receive a few weeks back the royal guard were doubled around the manor, for reasons why Naruto didn't know anything about the dark ones pushing through making themselves know, and Sasuke was planning for it to stay that way.

As it happens that Naruto was due to go into heat any day now, meaning he has to be kept stress free if the couple want a chance at conceiving a child, and that scared Naruto shitless. Why? Because most submissive male become weak during the pregnancy and birth and sometimes this leads to the death of the mother, child or both. Having the father or mate at the birth helps the submissive get through, although Naruto having speaking to Iruka on the subject of giving birth to a healthy baby dominant male, Ryuu.

Ryuu had silver-white hair with brown flecks on his small wolf ears, with chubby baby cheeks and a small button nose to the dark chocolate brown of his eyes, in short he was adorable but loud, really loud.

When Naruto and Sasuke went to visit the new parents at their house, Iruka decided that he wanted a house birth; Naruto was left with Iruka fawning and fussing over the new born whilst Kakashi went to talk to Sasuke outside.

"Iruka, it's good to see you in good shape!" Naruto exclaimed running towards his guardian with glee. Slowing down once he was close enough to see the bundle wrapped in a blue blanket snuggled into his mother's chest, latched and feeding from his mother's nipple. Peering in to the blankets he could see the little might.

"Aw he's so cute, so what's his name?" Naruto said in a hushed tone as Ryuu had finished feeding and now was staring sleepily at his mother and the stranger.

"Ryuu, his name is Hatake Ryuu." Iruka stated to his ward staring at his child who was only born the previous night and already so aware of his surroundings. Passing the babe over to Naruto to hold while he rested, tired from twenty-three hours of labour just to deliver one child.

"Dragon, that's a different name for a wolf cub. What was it like Iruka, to give birth?" Naruto questioned rocking Ryuu to sleep, helping Iruka in any way he can.

Iruka seeing this thought it was overly sweet, how someone with no blood relation can be so caring to a servant; it warmed his heart knowing he was cared about by more people than just his mate. Seeing Naruto holding his baby so protectively he could tell his young ward would make a fine mother and he was proud to be part of his upbringing.

"I'm not going to lie but it felt like hell, at first when the contractions came it seemed to be fine but as you dilate more the contractions become worse, then when the time came to actually give birth and push Ryuu out I thought I was going to ripe into two, or die which-ever came first but when I held him for the first time it made it worthwhile. Although I think I broke 'Kashi's hand." he chuckled at the end, thinking to how his mate complained to him afterwards.

Naruto could see that Iruka was struggling to stay awake so he offered to put Ryuu down whilst Iruka caught up on some well needed sleep. Gently singing to the baby when he became fussy never noticing the warm brown stare directed his way.

'Yes' Iruka thought as he drifted, 'I'm so proud of you, Naruto.' he thought as sleep finally caught up with him and he closed his eyes knowing his baby was safe.

After talking to his guardian and teacher, hearing how his hand was almost crushed by Iruka's grip when he was giving birth to Ryuu. Suddenly catching a scent on the breeze that drifted through the open window he realised that it was Naruto, but something was off. His scent seemed needy like his body was waiting to be filled with something, and then it occurred to him, Naruto's in heat and waiting for his mate to lay him and to be impregnated with possible pups or kits.

Normal their kind would go into heat when the seasons changed and fertility was at its highest. When male subs went into heat an opening between the testicles and the anus would appear leading to the womb. If the subs were from royal or noble blood they could go into heat early due to emotional changes or forcing the heat upon themselves.

Kakashi sensing the change in both Sasuke's and Naruto's scent decided that they could continue their talk at a later date, right now he had to escort the two now hormonal demons out of his house and get them back to the manor, without being mauled to death by an over-protective mate as he went to fish Naruto out of his and Iruka's master bed room with Sasuke following. Quietly opening the door he and Sasuke stop dead in their tracks as they saw how peaceful Naruto looked when looking after Ryuu, gently rocking the babe to sleep whilst singing and humming to a lullaby that his mother sung to him when he was this age.

Finally realising what had brought Naruto coming into heat made Sasuke's head fly with thought about possible starting a family of his and Naruto's own blood made the blood in his body travel south and a problem started to form when he thought of all the ways to get his little mate full of his seed and children.

"Naruto, come on love we have to go now." He whispered so that Ryuu wouldn't wake up and disturb his parents who looked to be in a peaceful slumber. Iruka, wrapped protectively in Kakashi's embraced who had left Sasuke's side in order to snuggle with his sleeping mate.

Looking up to his mate with red flecks in his normally blue eyes Naruto nodded, putting Ryuu down I his Moses Basket he turned to leave with his mate moaning slightly when him and Sasuke made skin-to-skin contact. Sasuke deciding it as easier to carry Naruto back to the manor when they left after locking the doors to Iruka's and Kakashi's house.

Stumbling into the master bedroom of the manor the royal couple who were both halved dressed half wrestling with the rest of the clothes and each other. It was, to Sasuke, maddening that his little mate was here waiting to be filled and Naruto was resting. Naruto on the other hand had let his instincts take control because of this felt the need to test his mate whether or not he was going to leave after filling Naruto with his seed. Finally after being able to pin Naruto to the floor he forced himself not to lose control when he came into contact with the heated entrance that was causing this state of mind, licking and probing the tight ring of muscle with his tongue, tasting the juices his mate was producing.

"Do you like that, me fucking you with my tongue?" Sasuke asked gripping twin globs of tan flesh, kneading them together making Naruto moan and whimper like the bitch in heat he was.

"Sas'ke, need-now!" Naruto manage to gasp out through the pleasure of being eaten out by his mate becoming too much to bear.

"What do you want Naruto, do you want me to fuck your little slut hole, fill you with so much of my seed that you are force to become pregnant with my child." Sasuke purred into Naruto's ear, grinding his hot and hard cock in the crease of Naruto's ass, before slowly moving his large cock to his mate new opening.

"Yes, oh god yesss, make me fat with your child Sasuke-sama." Naruto moaned as Sasuke mounted and entered him with great force, making both of them see stars, Naruto from the sweet spot in his body being abused and Sasuke with Naruto's body gobbling him up and swallowing him whole. Not giving the chance for the both of them Sasuke hooked his arm around his mates waist pulling him to Naruto's back to his chest and setting a relentless pace for the both of them that lasted all night through morning.

Outside however yellow eyes shone from the darkness, displeased with what the figure was witnessing, took out a communicating device a reported into mother base.
