High School DxD

Its been 10 to 20 years since they defeated/sealed trihexa via many people sacrificing themselves.

Many peope who got sealed along with trihexa were freed due to advancements in sealing magic developed by new reincarnated devils in respective peerages.

Issei's life dream came true.He became a harem king with over 20 offcial girls in his harem and many more admirers in all the realms.

On paper though,he only married three or four.

Rias,asia,kunou and gabriel.Last two being political marriages between forces.

Life was good for issei as the new Demon king in training.

But there was a small problem.

/

Issei woke up from his sleep feeling refreshed after another night of harem orgy.

He pushed away the naked and sweaty bodies of his harem members and put on a robe as he sat on the balcony chair for fresh air.

Since the weather in underworld never changes it was always a pleasant night sky.

Nowadays he spent more time in underworld since he didnt want to hypnotise his parents and his friends at the unchaning appearance due to pseudo immortality.

He only changed appearances when it was absolutely necessary when visiting earth as his parents were under impression that he is now working overseas at one of the gremory's main branches.

His musings wer cut short by two slender hands enveloping him into a hug from back asking "Thats a big frown you have issei.Something on your mind other tham sex?".

At this moment,issei knew specifically who the woman is just by the feeling of her boobs on the back of his head.Perks of being a boobs enthusiast.

Issei yanked the hand so that the woman fell into his lap as red hair clouded his vision.He started groping her ass saying"Good morning rias.Hope you enjoyed last night.Sorry i spent less time with you this month".

Even though he is free from burdens of saving the world.Issei was no means free and was instead busy managing several lessons from sirzechs and azazel,learning to manage human business from underworld and solidfying the alliances more by visiting various factions.

Rias was not dumb compared to her youngerself and asked"Stop issei.Tell me whats wrong.You have been kinda down these past months".

Issei knew he cant win against rias and explained his worry.

"Recently i have been bored and feeling empty. My dream as harem king came true.The endless sex was also good.Surrounded by boobs all time and able to do all sorts of perverted things to various girls was a dream come true.But something inside me feels empty,like a void that keeps growing.I cant explain it".

Rias listened to him quietly as she already sensesd the changes.She bet that some other girls also sensed it by chalked it up to simple stress.Only exception was asia as both her and rias herself noticed chances in issei.

One of the main keypoints is decrease in sexual prowess. Not exactly sexual stamina.Due to weilder of boosted gear,he can literally go for months on continous sex.But its as if he is loosing interest.

Rias felt guilty at herself and turned issei saying"Sorry is my fault.I failed to explain one major rules of being a devil. It not a big deal when you are lower to high class one.But it will be a major issue when you are nearing or are above high class category".

Issei was confused at her words as rias continued saying"Its sins.Devils are embodiment of sins and taboos.The farther you are to origin of our great mother lilith,the less influence you get.But the more closs you are,meaning the more powerful you get,the more you are **** to act on them.And you issei barely acted on your sins nor carnal lust".

Issei was never one for academic knowledge so this was completely new to him.He wanted to object about lust but rias guessed his thoughts and said" No you are mistaken issei.Iam mot talking about simple lust but rather pure carnal lust and sins.Take me for example,one of my carnal pleasure is being a nudist.I take pleasure at people seeing my naked body hence why i was naked many times during our youth.As for you,you have been indulging in sex and lust continuously but rarely acted on carnal activities or various fetishes that you humans categorize".

Issei absorbed all of it as he knew that rias was saying is true.He only indulged in fetishes when he have leisure time,after some years he felt that some things will be demeaning for his wives and he acknowledged that most of women feel disgust towards them.

Issei turned to rias asking"Is there a way to alievate?or help this condition?".

Rias thought for a while and remembered something saying"My mom once told me on all the etiquettes and things a wife must know when marrying a devil especially heirs of major familes.Let me ask her once".

Rias teleported away still naked as issei sat there contemplating on things he learned.
