Like father like son
"Father, are you going to watch Ria's promotion test?" Sirzechs who decided to take a break from his Maou work asked his father.
"Yes, I have finished my work today. Why not? Venelana has already gone there, watching her daughter's promotion test alone might make her a little lonely." Zeoticus said casually. In fact, his work as Head of House Gremory was not much, at least for now where the Gremory region did not have much trouble.
All of the Gremory clan's businesses were operating normally.
Their income and popularity were even increasing day by day, especially after his daughter, Rias had shown ultimate class power at her young age and according to Sirzechs... The girl's power might not be inferior to her elder brother.
The increase in his daughter's power could not be separated from the figure of his son-in-law, Eiji Seiya.
If not for that young man, Rias would not have been able to extricate herself from her political marriage with Riser.
Instead of being angry with the failure of the political marriage that cost his family, Zeoticus was proud of Rias and happy that at least the girl found a better young man than a pureblood devil like Riser.
The gains still outweighed the losses, so it didn't matter.
Every day, Zeoticus only had to review a stack of documents in his study. He usually only took two to four hours to finish.
The reason why he had free time now was because he had just finished dating his harem in his private residence that was separate from the main residence.
Sirzechs knew his father was only telling half-truths, although he was a little sorry for his mother who seemed to have lacked attention from her husband for the past year — for male devils with status and power like them having a harem was normal.
"Then let's go together. I happen to be going there as well, not only to watch Ria and her peerage, I just got word that the other faction leaders are interested in watching."
"What? They're coming to watch my daughter's promotion test? Isn't that a bit much?" Zeoticus was confused and wore a strange expression.
He had not expected his daughter's promotion test to be enough to gather many other faction leaders in one place.
On one side he was proud that Rias was his daughter, on the other side he was a little worried.
"Well they seem to know about Ria's promotion test from Zekram Bael announcing the test on DevilNet. Those people might be interested in watching just because they're bored. Me and the other Maou will be there, so..."
Zeoticus nodded. "So it should be fine, right?"
"Yes, father. Don't worry." Sirzechs said with a reassuring smile.
Having a son who became a Maou and was nicknamed the Strongest Devil in the underworld certainly took away his worries.
However, Zeoticus was still a little worried because right now his head somehow felt heavier than usual.
Before seeing what his wife was doing now, he had not expected it to be because he had a green hat on top of his head!
The teleportation magic circle shone under the feet of the two crimson-haired men, the next second their figures disappeared from Gremory castle.
...
Soon Sirzechs looked at his father with awkwardness and a hint of pity in his eyes.
"Mnnh~ Ohh~ Yess! Harder, Eiji-kun! Ahh! Ahh!"
In order to watch Rias' promotion test, of course they had teleported to the promotion test building. Now they were right in front of the VIP room door which the staff said had been filled by his mother.
However, who would have thought?
Before they could open the door, a familiar moaning sound stunned them.
From the sound of it, there was no mistaking it. It must be Venelana's voice!
Venelana was most likely inside with her son-in-law and they were doing...
"Father, this might be the wrong room." Even with his power as a Maou and his years of experience, Sirzechs wasn't sure how to comfort his father in this situation.
After all, in his life, this was the first time something like this had happened!
Of course if it wasn't Eiji, Sirzechs wouldn't hesitate to get violent because that man dared to give his father the green hat.
But that man was Eiji! The man who had previously taken his wife, Grayfia from him!
Given the power of his younger sister's fiancé, Eiji. The peace-loving Sirzechs who disliked spilling blood preferred to settle this matter through family means.
Even so, Maou Lucifer did not expect his father's reaction upon hearing of his wife and son-in-law's affair to be—
"No need to comfort me, Sirzechs. As a man who has been married to your mother for many years. How could I not recognize that it was her voice? It's really her, Venelana seems to be having fun with Eiji-kun." Zeoticus said with a wry smile, but it was not long before he seemed to relax as usual.
Don't know what kind of mentality the Head of the Gremory family had who clearly heard his wife moaning because of another man's penis but didn't get angry.
Now he actually seems relieved!
Zeoticus explained to his son. "We don't love each other anymore. Actually I've known for a long time that she was interested in her son-in-law, several times she often made excuses to visit Eiji-kun's house in the human world."
"Ahhh~! Eiji-kun, ahhh~ you cum! Cum inside~~ Give me your seed~~ Fill my womb with your sperm! Yesss! Yesss!"
"...." Sirzechs.
"...." Zeoticus' lips twitched, this was the first time he heard Venelana so excited during sex.
When he was with her in the past, she didn't moan that loudly!
His pride as a man was slightly hurt, but in front of his son, Zeoticus wanted to show that he was fine.
"Since then, we have also promised each other that we can go out with anyone. Your mother gave me permission to play with any woman and I also can't stop her if she has another man she likes."
"Father, you..."
"It's okay, now even though we're husband and wife, we actually treat each other as best friends. You know since last year, your mom and dad don't even sleep in the same room anymore."
"So it's been since then..."
"Yes."
The two crimson-haired men were chatting in front of the VIP room door. At first glance one would think Maou Lucifer and Zeoticus Gremory were having a good father and son conversation.
That was not wrong, but the topic they were talking about there and in that situation definitely made many people have strange expressions.
"Hnnnhh~ Again?! Eiji-kun is not only bigger than Zeoticus, he's also more durable. Mnnn! Ahh! Yess!! Eiji-kun. Fuck me harder, mnnnn~!"
In the room Venelana was already not wearing anything, she was completely naked like a big baby and lying on the table with a very sexy posture.
Her beautiful face looked very lecherous, her brown hair was disheveled. She wrapped her arms around Eiji's neck and her legs were pressed to the top of her head.
Eiji pressed down on his beautiful mother-in-law and fucked her in that position. This was their fourth round. The two start kissing passionately and his cock crazily fucks her pussy.
It stirs Venelana's nursery full of his seed and keeps beating her from the inside.
Right behind them was an unlocked door and they could feel who was standing outside.
However, neither of them cared.
They continue to fuck... Having an illicit relationship between the mother-in-law and her son-in-law.
Not only was the sound of kissing obscene. The room was also noisy with the loud and brutal sound of slapping flesh.
It was so loud that the two people outside could hear it clearly.
"Pffft!"
"Father?! We should get out of here, let's watch Rias's promotion test in my room and the other leaders. We can talk to mom and Eiji-kun later."
"O-Oh, this is... Okay."
His father vomiting blood, Sirzechs held the man's shoulder.
His mother's words that Eiji was bigger and more durable than his father were capable of hurting the man mentally.
Even though his father said he was fine, it didn't mean he was fine if his wife compared his to another man's.
And that other man was his son-in-law!
That was horrible...
Sirzechs felt sorry for his father.
Still, he could not help but remember the past where his ex-wife, Grayfia had sex with Eiji on the balcony.
Back then he heard that she also said Eiji was bigger and better than her which made him vomit blood.
They, father and son were given green hats by Eiji.
Sirzechs could slightly understand what Zeoticus was feeling, so he immediately took him away from there.
...
Separating each other's lips, a bridge of saliva was created between the two and was soon cut off.
The sight was erotic.
"Did you hear that, Venelana? Your husband and son seem to have found out what happened in this room." Eiji asked while continuing to bang on his mother-in-law's cave.
His clothes scattered on the floor, he squeezed the woman's breasts and occasionally bit her pink nipples.
Venelana continued to moan, her expression no worse than a bitch. She stuck out her hot tongue and her gaze fell on the screen displaying the Rating Game where the referee had just announced that Rias and her peerage would fight against Seekvaira and her peerage.
She was watching it from an upside-down position as her head was currently dangling over the edge of the table.
Venelana was almost crazy, she barely understood what Eiji was saying. But after some wet applause that echoed in the room and the moans that came out of her mouth.
Venelana said, "They? Mnhh~ I did hear their voices earlier."
Her son-in-law was so strong, he had cum for the seventh time that her stomach began to bulge. It was full of his seed. Even so, the huge serpant that knocked on her nursery until now was still as hard as a rock.
If she was not a high-class devil, she would have fainted by now.
She looked greedily at Eiji's muscular chest and stomach that looked like a work of art. Just like when he was fucking her, her hands also continued to caress his body.
Her son-in-law's figure was very good!
"You're not worried?" Eiji asked while enjoying Venelana's flesh wall squeezing his penis.
As expected of an experienced woman.
The woman's body was no worse than a Succubus like Sheila.
Even now, Eiji couldn't help himself to cum again.
"Ohhhhh~!" Before Venelana could answer, her stomach was pumped again which made her moan. Her body twitched many times due to the pleasure that fried her brain.
With a depraved smile that did not match her status as Duchess Gremory that would make many devils in the underworld dumbfounded if they saw her now, Venelana looked at her son-in-law's handsome face with lust and love.
"Don't worry, you also heard what Zeoticus said earlier. Fufu. Eiji-kun, you're very lucky, right? Ahhh~ It was easy for you to get this old woman."
"Indeed, I'm very lucky. You devils who have lived a long time can get bored and lose love for your spouse over time. But I won't let the same thing happen to me. Just like my other women. Venelana, you will be mine forever."
"Mnnnn~! You're very confident, I like that. But Eiji-kun, are you really capable of it?" Venelana who still had a lecherous expression, but her eyes looked provocative.
Eiji grinned, a purple magic tattoo began to appear on his beautiful and sweaty white neck of his mother-in-law.
Venelana widened her eyes, she felt a hot sensation on her neck that made her body more sensitive!
Eiji was still fucking her hard at that time. It was already very pleasurable before, but now the pleasure was doubled until she moaned even louder.
Her rationality had almost disappeared and she was on the verge of madness.
If it continued like this... S-She would become a whore for her son-in-law!
"You must have heard of it, at least from Rias because she has it too. On your neck is now a Master-Servant tattoo, you are now not only my woman, you are also my servant. For details... You should already know?"
"Ahhh~! Ahhh~! Yesss~! Eiji-kun, ohhh~! You really made me your slave~! I like that, more! Fuck me as much as you want!"
Hearing his mother-in-law's plea, how could Eiji refuse? He laughed and started kissing her mouth again.
Satisfied with Venelana's pussy, he changed their position. He made her get on all fours while facing the screen showing Rias and Seekvaira's match.
He grabbed her brown hair and started exploring a new, narrower, dirtier map.
"AHHHH! Eiji-kun! Eiji-kun~! No, that's my ass, Ohhh Yesss~ smash it~!"
Feeling Eiji pull out his penis from her pussy and insert it into her ass hole, Venelana felt that this time she was really going crazy.
The tiny hole was crammed with an object even bigger than her wrist. It penetrated deep into her belly and churned her up.
This was the first time Venelana had ever felt anal this good.
Actually without the Master-Servant contract whose details she already knew from Eiji's inner voice, and Rias in the past. Venelana doubted she would get bored like she did with Zeoticus and like other men besides Eiji because Eiji was too amazing!

[You successfully obtained Venelana's Heart Key.]
[Venelana's Heart Key was detected to match one of the 72 Pillars, Bael.]
[You have unlocked Bael!]
Eiji saw the notification, but he didn't care at all and vigorously fucked his mother-in-law while watching the Rias match.
...
Meanwhile.
A man with sunglasses, an aloha shirt, shorts and flip-flops sat in the same room as Sirzechs, Zeoticus, Azezel, Michael, Odin and several other people.
With his appearance like that, among the Ultimate, Satan and God class beings that were there, he looked out of place.
Even so, none of those there took issue with the way she dressed to gather with them.
"HAHAHA! Is that your little sister, Sirzechs? Oh, that's interesting. At her young age, not only is she very beautiful, I can feel it, she's very strong! It's no worse than when I hit you last time."
The man dared to speak in a mocking tone to Sirzechs.
Sirzechs was not angry, he smiled. Even so, they could see his eyes were not smiling at all as he looked at the man.
