Serafall who feels green

For Serafall, although she had already accepted her younger sister's engagement to Eiji, this was the first time she knew the two people had had sex!

Of course for a woman who loved her younger sister as much as she did, Serafall in fact still had an aversion to seeing Sona being fucked by someone.

And that person was Eiji!

Not only Eiji, after helping Sirzechs and the others to announce the results of the conference and the attack by the people of the Khaos Brigade to everyone in the Underworld.

She originally thought of meeting Eiji to keep her promise, and she found out he was taken away by Sona to her private mansion with the other girls. She teleported there, but what greeted her was the hot sight of Eiji having sex with three girls at once!

One of them was her younger sister, Sona. And the others were Rias and Akeno. It made Serafall who originally wanted to say hello or something stunned in front of the door and just stood still while peeking through the crack of the door.

Putting aside Rias who fainted from the bedside with a bulging belly and white liquid flowing from her pussy, she was aroused to see Eiji fucking a girl as sexy as Rias hard before. Please note, Serafall was actually a woman who liked women rather than men. Besides liking her younger sister rather excessively, she also liked beautiful women.

But that was it, she never played with those women because she always thought of maintaining her own chastity for her younger sister's sake. Although she knew those things were unlikely to happen because Sona was normal, she liked men like Eiji more romantically than her older sister.

It made her sad, but Serafall secretly had hope because she had the idea of becoming one of Eiji's women. What she said not long ago if Eiji agreed to revive Sirzechs only convinced herself to stop avoiding her promise to that man. That way, wouldn't it be in this situation that she could join one man and three beautiful women including her younger sister in the room?

Just thinking about it made Serafall extremely aroused and drooling on her pretty face, the first time she heard Rias and the others moan she had already put her hand inside her panties and played with herself.

Damn it! Serafall didn't have the habit of cursing, but besides being horny, she was also very jealous of seeing Eiji being served by girls as beautiful as Sona, Rias, and Akeno. As for that guy, she actually wasn't sure how she felt about him.

At this point, she knew she at least liked him more than other men, but it still didn't compare to her fondness for her younger sister!

Siscon! Serafall knew she was one of those people in this world.

And besides being horny and envious, she also actually felt pain in her heart when she saw her younger sister, Sona being brutally fucked by Eiji and even more so Akeno also participated in inserting a penis-shaped toy into her pussy.

Ah! Ah! She, Serafall had never even done that to her younger sister! Looking at Sona who made such a lewd expression like a whore while being fucked by those two, she felt a sting in her heart as if she was seeing the woman she liked being raped by someone else in front of her eyes.

She also felt angry of course and even thought of stopping Eiji and Akeno who were fucking her younger sister.

But... But... For some reason, she continued to be stunned at the door, and watched her younger sister who continued to moan, plead, shed tears but her expression looked happy as if she felt very delicious when her two holes were plugged simultaneously.

'What happened to me? Could it be that besides Siscon, I'm also a voyeur?'

'N-No way!

Serafall denied, but her gaze did not flicker as she watched Sona squirt liquid from her pussy that was blocked by Akeno, and she screamed very loudly as Eiji's penis that was blocking her ass hole squirted semen into her.

This climactic scene was more enjoyable than all the Magical Girl episodes she had ever watched.

"Pop!"

With that popping sound, she saw Eiji pull out his penis, a big, long, delicious-looking meaty rod with white juices from her sister's ass hole. Akeno also took the toy out of her sister's pussy, Sona seemed to have passed out with a lecherous expression and her belly bulging with cum.

Serafall gulped, with her vision as an Ultimate Class Devil, even if it was only from the crack of the door and the room had dim light, she could clearly see Sona's ass hole gaping, twitching repeatedly, and spilling a lot of white liquid like a waterfall onto the floor.

Eiji's penis too, she could clearly see the size of it reaching 7 inches, it was so long and thick that she was surprised that such a big thing actually entered Sona's small body.

Due to the stimulation from the things she had watched, Serafall also had an orgasm.

"Hmnn~~"

She tried to stifle her moans as her short legs felt soft and she knelt in front of the door with her own juices splattering the floor.

Her face was flushed and sweat was already dripping from her face. Maou Leviathan, Serafall Leviathan looked helpless after orgasming from watching her sister climax.

She sat on the floor in a daze and wondered should she call the people in the room now?

She saw Eiji laying the already unconscious Sona beside Rias, so those people should be done by now...

"Akeno, now it's your turn. Tell me, do you want the front door, the back door, or both?" Eiji's voice still sounded energetic, Serafall could even see the boy's penis still raised like a sword after cumming so many times.

This man... Is he still not satisfied after cuming that much inside Sona and Rias?! Although Serafall was a virgin devil of more than 100 years, she naturally had the common sense that a man could only cum a few times a day at most. Many male devils in the underworld, regardless of their power also have a limit to cum.

But Eiji, she remembered that boy had already cum more than 10 times and he could still do it again after that?!

"Fufu you can still do another round, Eiji? That's good~ Now it's my turn, I also want you to use my two holes simultaneously."

Akeno, Rias's Queen who looked like Yamato Nadeshiko was very lewd. She inserted the dildo she had used on Sona into her own ass hole before crawling in front of the door and raising her ass to Eiji.

"Sure, you want to do it in that position?"

"Yes~"

Eiji complied with the woman's wishes and they again did it in front of her! Serafall hesitated, obviously she came here to keep her promise, but in the end she was just watching people having sex in front of her!

Not knowing how much time had passed, to the sound of obscene moans and loud claps of flesh, Serafall orgasmed multiple times seeing what she was watching. From how Eiji rode Akeno in various positions while piercing both of the girl's holes with his penis and the dildo in his hand.

In the middle towards the end, Serafall even saw a new world where objects such as ropes, whips, handcuffs, and dog collars were played with.

Unlike the way Eiji fucked Rias and Sona, Eiji played S&M games on Akeno and the girl continued to be tortured by him until morning.

...

At nine in the morning the next day.

After Eiji woke up, no, he actually didn't sleep at all and was just lying down with Rias who was hugging his left arm, Sona who was lying on his chest, and Akeno who had many red marks hugging his right arm.

The three girls were still not awake after the debauchery they had last night. Eiji didn't wake them up, he quietly broke away from their embrace and went to take a shower.

Although he could clean himself with magic, he was in the mood for a normal bath. After refreshed and dressed, he cleaned up the chaotic battlefield with his magic including the girls whose smell was mixed with his semen and made them sleep comfortably in their respective nightgowns.

As he opened the bedroom door, he glanced at the empty hallway but under the floor he saw a small puddle.

Obviously it wasn't because Sona's roof tiles had leaked and spilled rainwater, after all there had been no rain at all last night.

With his perception he of course realized that last night Serafall continued to watch their debauchery from the crack of the door until morning.

And those puddle marks were none other than the fluids of the Magical Girl who had orgasmed many times watching him fuck her sister, and the other two girls.

"Beautiful morning, but where is that woman now? Tsk, she left... Oh?"

Eiji smiled, he walked to the front door which currently heard the sound of the doorbell ringing repeatedly, before he opened the door, he had stopped smiling and put on an indifferent expression.

Opening the door, in front of the door of Sona's house he saw Serafall who was smiling as if she had just arrived. However, there were a few black bags under her eyes that let one know she had not slept well last night.

Oh sure, who peeks at people having sex last night until morning and leaves only to come back after a few hours as if nothing happened.

"Eiji-chan, morning~! Is Sona awake too? Last night you guys must have had a wonderful night!"

Don't know if it was a sincere good morning, but there was sarcasm in it and the woman gave him an annoyed look even though she pretended to be cheerful as usual.

"Is this sister-in-law? Yes, Sona and the others aren't up yet. You just go in first."

"The others? You mean there are also other girls staying at Sona's house?" Serafall entered, Eiji closed the door and the two walked into the living room. While walking side by side, Serafall, the woman was acting.

Eiji didn't glance at the woman and simply said, "There's also Rias and Akeno."

"Rias and Akeno? Eiji-chan, you pervert! Did you and those girls also..." Serafall seemed to be trying to joke to cover up her guilt because last night she basically didn't keep her promise, but what she received from Eiji was a perfunctory response.

"Well... You're right."

Serafall pouted, she could feel that Eiji's attitude towards her was colder than usual, actually since meeting at the Peace Treaty conference as well besides her taking the initiative to talk to him, Eiji basically ignored her more.

This made her uncomfortable, and knew that she must have made Eiji feel annoyed at her.

Sitting in the living room, the two of them sat side by side, Eiji turned on the TV that was showing the news in the Underworld and it happened to be about the Three Faction Peace Treaty that was successfully carried out. The Underworld also certainly has a TV station because its technology level is also actually not much different from the human world.

With his magic he also created an Egg Sandwich and he made two because there was also Serafall sitting not far beside him.

"How convenient. Eiji-chan, you can also make food with your magic?" Serafall who hadn't had breakfast yet didn't hesitate to eat the sandwich filled with eggs, sausage, pickles, and tomato sauce in her hand. Her eyes lit up because it tasted so good!

She ate her sandwich while glancing at Eiji who was eating his sandwich with one hand while staring at the TV. The calm blue eyes without any waves seemed to have many small stars in them when viewed up close, his sharp and angular facial features made him look very handsome, and his silver hair did not help but make him look like an anime protagonist. This wasn't the kind of protagonist like Issei, Rito or other protagonists who had been looking bad of course, but the kind of protagonist who was handsome and popular among women.

Harem protagonist! With a face and figure like that of a male god, it's no wonder many heroine including her sister fell into Eiji's hands.

Even she, Serafall was dazed and her heart beat faster when she realized that this man was definitely more handsome than the last time she fought with him!

If seen up close, this man was undoubtedly more handsome than Sirzechs who was famous for being the most handsome and powerful man in the Underworld.

"Yes."

"...."

Hearing another perfunctory answer from Eiji, Serafall's lips twitched, this man was clearly not happy with her!

I know! It must be because last night I again did not keep my promise! But! But...! Last night wasn't easy either, okay? I saw you fucking my sister and other girls.

While I was also turned on by what you guys were doing, I also felt upset and hurt seeing my sister being fucked by you and Akeno!

So I... just...

"Eiji-chan, did you hear what the host said on TV? Sirzechs-chan and I announced that you became the hero who saved everyone at the Three Faction Peace Conference! Everyone in the Underworld must have heard your name by now."

"Oh."

"And many important people in the Underworld want to meet you, but you don't have to worry. Sirzechs-chan and I can hold those people back and it's up to you whether you want to meet them or not. By the way among them there are also many reporters from all the TV stations in the Underworld."

"Okay."

"Also... Also... There are many girls from noble devil families who invited you to the tea ceremony! Although polygamy is possible in the Underworld, but I refused them and said loudly that you are already engaged to Sona-chan and Rias-chan! There are also other girls who have become part of your harem. I said you already have too many women, so you're off limits!"

"...Unfortunate."

Eiji sounded sorry to hear that and frowned as if annoyed, Serafall's lips twitched again. Okay, was I wrong? You're still not satisfied with the size of your harem? Also can you stop answering perfunctorily like that?

Serafall felt increasingly uncomfortable with Eiji's attitude towards her, she finished her sandwich and puffed up her cheeks.

She got up from the sofa, with both hands on her waist, she stood in front of Eiji who was watching TV.

"...What are you doing, Serafall? You're blocking me from watching TV." Eiji expressionlessly said, he didn't sound angry or annoyed, but it made Serafall even more uncomfortable.

"Eiji-chan, tell me. Are you angry?"

"I'm not angry."

"Lie!"

"What's wrong with you, Serafall?"

"You called me Serafall! And at the door earlier too you called me sister-in-law!"

"Isn't that the correct way to call?" Eiji looked at the woman strangely as if to say so what should I call you?

"No! Didn't I tell you long ago to call me Levia-tan or Onee-chan!"

"You think too much, it's just that I prefer to call you Serafall or sister-in-law." Eiji said and soon his inner voice was heard.

¶{Levia-tan? Onee-chan? Forget it! Why should I call you like that? We're not that close.}

"Look, you're angry!" Serafall's cheeks were already like a pouting hamster.

"What did I say? Didn't you hear me wrong?"

I didn't hear you wrong! I heard your inner voice!

It was a pity that Serafall could not say things about inner voices, and in the end she asked again. "Is it because I didn't keep my promise last night?"

Eiji pretended to be confused and remembered something. "Promise? What promise... Oh? You mean the things you said to persuade me to revive Sirzechs? Don't worry, I didn't think much of it from the start."

"You! What do you mean?" Serafall widened his eyes.

Eiji looked at the woman calmly and said, "I mean there's no need to think about the bet we made in the past anymore. I'm honestly worried that Sona will be in trouble when she finds out what bet we made. So forget it."

"Your concern has merit... But! But! Eiji-chan!" Serafall seemed to have trouble accepting what she said. The woman seemed reluctant.

Also, who not long ago did not accept and reject Grayfia's offer to become his personal servant? The silver-haired woman was Rias' sister-in-law! Isn't the situation more tense than me and Sona?!

And right now don't think I didn't notice your gaze occasionally glancing at my breasts! This man's mouth is clearly dishonest!

Eiji raised his eyebrows. "What?"

"....." Serafall opened her small mouth, she seemed to be deep in thought as her pink eyes stared at him with complicated look. But what she heard in her head next left her shocked and embarrassed.

[But what? Did you think last night I didn't know you actually came and peeked at what me, Sona, Rias and Akeno were doing? With my power, how could I not know a woman was peeking through the crack of the door.]

[And that woman did not keep her promise, from night to morning, she continued to watch as her sister made love behind the door secretly. Not only siscon, you are also a voyeur!]

---!

Serafall's face turned red, she had been caught peeping last night! And this man, Eiji was actually pretending not to know, very much in line with his character who likes to pretend!

But the point is that she was embarrassed and wanted to find a hole to hide in! Being a devil who has lived for so long, it's not like she wouldn't feel embarrassed to be caught peeping at people with her current status.

Even so, she did not do so and looked at the handsome man sitting in front of her with a narrowed gaze.

Obviously the man was greedy for her body, but pretending to be reluctant? Snort!

"Serafall, what are you doing?" Eiji widened his eyes as if surprised.

Why? It was because Serafall suddenly jumped onto his lap, grabbed his shoulders with both hands and pressed his hard against the sofa.

Her pink eyes stared at him like a she-wolf ready to bite him at any moment.

[Is this woman crazy? Your sister is sleeping not far upstairs. What do you want to do? I told you to forget about your promise!]

[And I honestly don't want to accept Yuri in my harem either. Do you think I don't know you don't really like me and are only interested in joining my harem because your sister is there? Heh Serafall, unless you become normal, there's no way you're joining my harem!]
