AN: This is a one-shot that I may turn into a full story later if it receives enough favorites.

Chapter 1: The breeder devil one shot

Warning Lemon ahead...

We see Naruto, the heir of the Phenex clan, lying in bed, his eyes slowly opening as he gives a groan, feeling a wet sensation around his cock. He raises his sheet, revealing his naked body, and sees his mother, Layla Phenex, in a lustful trance, looking up at him with hooded eyes while she suckles on his morning wood. She's bobbing her head back and forth, never letting up the deep suction her mouth has around his cock. Not long after that, the blond male releases his seed down her throat, which she swallows every drop.

"That was a good wake-up call," Naruto said as he pulled her naked body onto his lap. She was panting with lust, her large breasts leaking milk and her glistening cunt.

AN: The full Lemon will be place on another site.

Lemon over...

Naruto gave her stomach a rub feeling their baby kick. He smiled before getting out of bed. He stretched his joints before making his way to his shower. After he was ready to leave his room, his mother snored soundly on his bed. He exited his room and was met by RoyGun Belphegor in a skimpy maid's outfit. She had a blush on her face and refused to meet Naruto's eyes.

Then the blonde remembered his past life and how he ended up in this situation. He had been reincarnated after being killed while helping his son Boruto fight the Otsutsuki king; he was now Naruto Phenex, the firstborn son of his parents.

Born with his past memories, he grew up and found that he couldn't use chakra in the same way as before; he didn't have a chakra network, so he learned how to form the Youkai of this world. He had relearned how to use it and recreate his old abilities. He also possesses the magic and abilities of the Phenex clan.

Growing up, he was considered a prodigy and was classified as a Super Devil. He learned how to combine his sage powers with his magic, creating something even more powerful. He was one of the devils who fought against the old Satans during the civil war, and was offered a place as a new Satan, but he rejected it.

Naruto was able to create a potion using alchemy by combining the Phenex's tears with his recreated Yang Seal; he created a fertility potion that boosts the birth rate of supernatural beings. It has a side effect of making those who drink it temporarily insane with lust, but that is only temporary.

Thanks to this potion allowing him to create around 6 a month, the Phenex clan became one of the richest clans in the supernatural world. Naruto himself had many lovers and even more children. From his own mother to the extra demon in front of him, goddesses, devils, fallen, angels, and humans.

Naruto walked over to Roygun and placed his hand underneath her chin, lifting it up to look her in the eyes before giving her a soft kiss on the lips, causing her to blush even deeper.

Naruto chuckled before he walked to his office with Roygun following behind him; he remembered she was one of the strongest ranking players by using the King Piece which was illegal to use. He was bored and challenged all of the top ten strongest players by himself, he crushed them all. Roygun being arrogant at the time offered herself in a wager if he won, in exchange for half of the profits the Phenex Clan made off his fertility potions. Needless to say, she lost and was knocked up within a week.

Roygun is now the mother of three of his children, as she was banned from the Rating games after she was caught cheating by using the king's piece. She wasn't punished because at that time she was pregnant with his child, and he used his influence so she only got a slap on the wrist.

The funny part is Roygun as she is now is stronger than when she used the King Piece, it seems that his sage and magic abilities strengthen his mate's body's physical and magical abilities. The more he has sex with them the stronger they get, his mother as she is right now is as strong as a Satan.

He was basically the leader of the Phenex clan at this point, as his father spent most of his time fucking his harem and partying. You would think his father would hate him for stealing his wife, but it was the opposite; Layla always made him take care of his responsibilities, and while he grew to love her over time, their marriage was arranged, so they never were able to find a lover for themselves. In the end, he gave them his blessings and left the clan's business to him, while he partied like a college student.

As he thought of marriage, his mind went to his little brother's arranged marriage with the Gremory heiress; he knew Sirzechs wouldn't let it happen, after all, what father would want their daughter unhappy? He thought with a smirk.

He remembered it as if it were yesterday. Sirzechs had been making fun of him for being a motherfucker and wouldn't shut up about it. In response, he got revenge by dosing his and Venelana his mother's food with a fertility potion, then locking them in the dining room together within a barrier. It was something to see the way they went at it. He of course recorded it, and thus Rias Gremory was born.

It was an open secret among the older devils that she is Sirzechs daughter, but the younger devils, including Rias, didn't have a clue. He sent a copy of the recording to almost every devil clan and now Sirzechs was known for cucking his father. It almost came to blows between them but the other Satans stepped in.

The funny part is that he was sure Sirzechs was still fucking his mother as she started showing a baby bump and her husband was away on clan business.

Shaking his head and returning to reality, he entered his office and sighed as he saw the amount of paperwork. This was just another day as the new Lord Phenex.
