1. Reincarnation or Transmigration

The man known as Haruto Seiya opened his eyes as he groaned and raised his head from his desk as he rubbed his face. He blinked a few times before he realised where he is as he looked around.

'I-I am in another world?' Haruto though to himself as he looked at the office.

He got the memories of the man in this world as he held his head and groaned silently before he got a hold of himself. He realised that it is time for his shift to be done as he did the rest of his work to not make others suspicious.

'Okay, my name is Haruto Seiya and I am a married man huh. Hmm, right, he is part of that doujin huh. Okay, that can wait until after my work is over.' Haruto thought to himself as he did his work.

Soon he was finished as he walked out of his office building and went to a park and sat there as he recollected the memories from both his lives.

'Okay, so I died in my previous world. Met with a God or angel or whatever it was. Then it was decided that I can reincarnate and it was chosen to be a hentai world. Though he did say that the focus would be femboys due to my orientation.' Haruto thought to himself as he remembered it.

Haruto was attracted to the feminization hentai. He has always had an inclination towards Domination, which usually manifested in feminization, hypnosis and other hentai categories.

Owing to that he was informed that the world he is in will also have a good amount of feminization hentai characters as well, though he didn't find it as problematic. As far as he is concerned, as long as they look feminine, he has no problems.

After that came his powers and he pondered over it for a while as this is a hentai world. Where crazy things can happen and it's hard to keep a track of it. He was also informed that the world is much larger than his own due to the change which he accepted.

He then decided to get Sexual Mastery as that is what is needed in the hentai world. Not to mention the fact that if he wants to feminize the people here then he has to make them feel good as well.

He then wanted to get a very powerful body for himself so that he can't be killed so easily in case he finds himself in danger. He also couldn't ask for any abilities that are overpowered so he couldn't get the powers of Hagoromo.

So instead he asked for the abilities of the demons from the Demon Slayer universe, but without the need for drinking blood, weakness to the sun, he also wanted the ability to eat freely unlike with the demons, the ability to have endless amount of blood in him, essentially eliminating the need to feed on humans to live while having all the abilities of demons without any drawbacks.

He took this decision because the demons have great versatility as well which can help him, as long as he develops it.

And last but not least, he asked for the power of hypnosis and the ability to be immune to hypnotic powers as well so as to make sure that he doesn't fall under the effects of another. With all these three wishes, he was reincarnated or transmigrated into the new world.

"Hmm, but my body feels the same, maybe it will take some time for me to get my abilities?" Haruto muttered to himself as he sat there.

Then a note appeared on his lap as he was surprised by it and read it. On it, it was written that he will get his abilities when he sleeps, which caused him to hum in understanding before he walked to his home.

'Now then, if I am remembering it correctly then this guy's is being turned into a sex addicted woman using hypnosis video. And from the memories, it looks like she is starting to get violent and more irritable towards him, well, me. But I guess I can fix that.' Haruto thought to himself as he walked.

"Seriously though, this guy needs to work out." Haruto muttered to himself as he looked at his own body.

He soon reached his apartment as he walked inside and announced his arrival. His wife came and greeted him, though she was a bit detached about it but he didn't mind it as he walked inside.

'Her name is Yuri if I'm remembering it correctly.' Haruto thought to himself as he looked at her.

"I'm going to take a bath." Haruto said as he started to undress himself.

"Okay, I'll put the food at the table." Yuri said to him as she went to the kitchen.

He then went to the bath and sat in the tub as he sighed to himself as he remembered her behaviour.

'It looks like she is halfway through it. But maybe I can still get her. She is also a pretty woman with a nice body after all. Why doesn't he cherish her more?' Haruto thought to himself as he looked at the ceiling.

He sat in the bath and then walked out and changed into the clothes he brought to the bath. Then he went to eat with her as his wife is already at the table as he looked at the food.

"They look delicious." Haruto said with a smile as he looked at her.

Yuri looked at him a bit surprised at his words before she frowned and nodded to him. Then the both of them started to eat as he enjoyed the food as he liked it.

After that he watched the TV with her after he told her, though he could see the frown on her face. He put his arm on her shoulders which caused her to slap his arm with an indignant look as she glared at him.

"What are you doing?!" Yuri shouted at him in anger.

"I'm putting my arm over you, is there a problem with that?" Haruto asked as he looked at her.

"Of course there is a problem. You can't just put your arm on me!" Yuri shouted at him in anger.

"Yeah, well I'm your husband and I can do that." Haruto said to her as he stood up and glared at her.

Normally she would've backed down when he acted this way, but due to the events of the doujin she has become more irritable, frustrated and angry, which is why she is glaring at him when he said that.

"Well then you can't! You're not supposed to touch me!" Yuri said to him in anger.

"Oh yeah, well I can cause I'm your husband. I'm supposed to touch you!" Haruto said raising his voice a bit.

"And I'm saying you can't! So shut up and don't ever touch me again!" Yuri shouted at him in anger.

*Slap!*

"Kyaa!" Yuri cried out in pain as she fell on the floor.

She cupped her left cheek and looked at him as she saw his right hand raised in the air as he glared at him as she looked at him shocked. But then Haruto looked at her surprised as went and kneeled in front of her.

Yuri felt fear for her husband for the first time as she looked at him scared. He raised his right hand as she looked at him with fear in her eyes. But then he gently cupped her face as she looked at him in surprise.

"Oh my gosh, I'm so sorry. I didn't mean to hit you like this." Haruto said to her in a caring tone which surprised her.

She looked at him as he removed her hand and looked at her cheek which has his handprint.

"I'm sorry Yuri. I didn't mean to slap you like that." Haruto said to her in a caring tone as he softly rubbed her cheek.

Yuri looked at him in shock while some tears formed on her eyes as she looked at her husband. Then he hugged her as he put her face on his chest as she was surprised by it.

"It's just that you have been acting so weird lately. You don't smile much and you are always angry, I was getting frustrated." Haruto said to her as he rubbed her back.

Yuri's eyes widened when she heard that as she remembered her interactions with her husband.

'That husband of her's didn't seem to try to mend their relationship despite it starting to deteriorate, I'm not going to let that happen though.' Haruto thought to himself as he hugged her.

"I love you Yuri. I want to help you, but I can't do it unless you tell me what is troubling you." Haruto said to her as he pulled her back and looked at her with concerned eyes.

Yuri looked at him with wide eyes as she didn't expect him to say those things. At that moment her escapades came to her mind as she looked down, feeling guilt as she remembered it.

Haruto sighed at that and then planted a kiss on her forehead and hugged her gently with her face on his shoulder as she was surprised by his actions.

"If you don't feel comfortable talking about it then don't. But remember that I'm here for you okay. You can tell me if you have any problems." Haruto said to her as he rubbed the back of her head.

Yuri's eyes shook when she heard his words as she frowned and then hugged him back as she felt the body of her husband.

They stayed like that for a few minutes before they separated. He mouthes another sorry to her before he offered to clean the dishes. She looked at him dumbfounded as he worked.

'Seriously though, he isn't that tired that he can't even do the dishes.' Haruto thought to himself as he worked.

After that the both of them went to bed, but this time he hugged her from behind her as she was surprised by it as he wrapped his hand over her stomach while hugging her.

"Goodnight Yuri." Haruto said to her as she heard him.

"G-Goodnight." Yuri said with a stutter as she placed her hands over his own.

'Hmm, looks like it is working. Guess that slap was enough for her to get back some of her sense.' Haruto thought to himself as he hugged her.

Soon, the both of them went to sleep and his transformation started as his body glowed faintly for a few minutes before the glowing stopped. Then Haruto opened his eyes which had become red and with slits as he looked at his wife.

'I can feel my entire body, wow.' Haruto thought to himself as he slowly freed his arms.

He got off of the bed while making sure that his wife doesn't wake up and slowly left the room. After that he looked at his body and smiled at himself as he removed his clothes and stood in front of a mirror. Then he started to change his body as it became muscular and fit as he smiled at himself.

"Oh yeah." Haruto said to himself with a smile on his face.

'Oh this is wonderful. Now I just have to make sure that Yuri fully comes under my control. There is no reason for me to lose such a beautiful woman.' Haruto thought to himself as he smirked to himself.
