Esper Harem in the Apocalypse

"This will be my first time drinking blood directly from a body. But you are now used to it since Jane sucked your blood many times."

"That reminds me of the promise."

"What promise?"

"You are not allowed to drink anyone's blood other than mine."

Rias squinted her eyes and asked, "What type of promise is that? And did Jane agree to it?"

"Yes."

"Really?!" she asked with a surprised look on her face.

"Yes."

"Hmm." She hummed in wonder and said, "Okay. I don't actually drink blood. Maybe once a month or something since I don't feel an urge like the other vampires."

Rias licked Rudy's neck and whispered, "I will be digging in."

"Wait, before you do it. Can I do it on you too?"

"What do you mean?" she asked with a puzzled look on her face.

"Can I mark you too?"

Without replying, Rias buried her fangs into Rudy's neck and sucked his blood.

'I noticed this before that it really feels different. When Nyxia sucked my blood, the feeling was different. Nyxia's fangs were sharp and long, so she went deeper and drank my blood faster compared to Jane.

Jane's fangs were a little smaller than Nyxia's. Rias' fangs are the smallest, so she can't reach deep, and she has to force the suction to drink my blood. But I would never dare to say it out loud to her.'

The wings and fangs were considered as a vampire's pride, and saying something against them could be considered offensive. Rudy wished he knew that before he compared Nyxia's wings with Jane and got his body dried by Jane, quite literally— although Rudy enjoyed the punishment and he was not a masochist.

Rudy also elongated his fangs and was about to drink Rias' blood, but he remembered what Nyxia had told him about the vitality.

Rias was closest to being a human. The only difference was that she had fangs and wings. She didn't even have any vampiric abilities— even the basic ones such as charm and form changing.

'I don't think I should do it. But… what if I don't drink her blood?"

Rias spread her wings and covered Rudy's body in them.

'The ritual is about to end!'

Rudy buried his fangs into Rias' neck, but instead of drinking her blood, he released the power he had absorbed from the blood moon tree.

"Anh!"

Rias's body tightened, and she drank Rudy's blood in big sips.

After a few minutes, they let go of themselves and stared at each other.

"Did it work?" Rudy asked curiously.

"It should have. I think I did everything correctly." She gazed at the red moon and uttered, "There is the red moon, we also had direct body contact, and I covered you with my wings."

"Hmm." Rudy hummed in amusement and said, "It's surprising how Jane wasn't aware of what she was doing even though she has read too many forbidden books and all. But you knew about it."

"Well, the marriage ritual is not forbidden. And… Jane never had any interest in this girly stuff, so she probably skipped the chapters about it," Rias replied with a shoulder shrug.

Rudy chuckled and nodded while saying, "That does sound like something Jane would do."

Rias hugged Rudy tightly and said, "We are married now."

"Yes."

"I am your wife, and you are my husband."

"Yes."

"Do you love me?"

"Yes."

"Are you happy that you married me?"

"Yes."

"Will you cheat on me again?"

"Yes."

"What?!"

"You are probably referring to my harem and the new girls who might join in the future…"

"You plan to add more girls to your harem?!" Rias exclaimed.

"I mean… that seems inevitable, to be honest." He shrugged his shoulders and continued, "I have to look for a partner who can dual cultivate with me. And now that I have learned about the existence of the other races, I might run into them."

"Geh! I should have become the Queen of your harem, after all! And limit the harem members too!"

"Don't say that. I have a big heart, and it has a place for everyone to stay in," he said with a grin on his face.

Rias shook her head in disbelief and muttered, "What happened to the old Rudy? He was so cute and shy, and it was fun to tease him."

"He evolved into the super Rudy," he scoffed softly. "Jokes aside, I, of course, don't plan to add every girl I meet into my harem. Only the ones I love."

"How many girls do you have in your harem again?" she asked with a curious and judging look on her face.

"The expression on your face doesn't suit you," he muttered.

"Tell their names, races, age, and whether you are intimate with them or not," Rias demanded.

"Wow. What is this, a harem interview, or should I call it a harem interrogation?"

"..." Rias stared at Rudy without saying anything.

SIGH!

"First is Angelica, and she is the one I lost my virginity to. She is a ghost, and she was in high school before she died. And yes, I have had lots of sex with her.

The second is Alice, and she is my childhood friend. She is a human and the same age as me. I have kissed her, got a blowjob from her, and eaten her pussy.

The third is Reina, and she is also a human. She is 20 years old if I remember correctly, and I have gone all the way with her.

Then there is Jane, you, Niti, and Nyxia— but she is not confirmed. And there are a few girls I want to add, but that was the list of my current harem members and my status with them."

"Out of seven…., four of them are vampires…"

"And note that Jane and Niti were the only girls I made moves on. The rest loved me, so it was natural to add them."

"So…" Rias wrapped her arms around Rudy's neck and kissed him on the lips before asking, "When are we going to do it?"
