Esper Harem in the Apocalypse

"You…. you kissed me…" Rias placed her hand on her lips and asked with a flushed face.

"I did. Want one more?" Rudy said jokingly so Rias' mood could quickly change from embarrassment to haughty.

"Umu," Rias nodded.

However, Rudy failed miserably. It was a 'mission failed successfully' situation for him.

'Seriously. I already have a boner by kissing her. Dear mom, please help me with this tempting test!'

Rias puckered her lips and waited for the kiss, and Rudy knew he had to do it, or his image in Rias' eyes would be labeled as a 'NoBaLLzMaN'. He had to prove that he had the balls of gold and not all talk.

Rudy slowly moved close to Rias and kissed her once again.

"...!" Rias' face flushed a little more after the kiss and she licked her lips. Then, she slowly opened her eyes and said, "I am angry."

"What the—! You are the one who asked me to kiss you again."

"No, not that." Rias shook her head and said, "I am angry because you kept me waiting and came late."

"Oh, I see we are still hung up on that."

"I was so anxious! I felt like I was going to die in loneliness!"

"I understand. So what do I have to do or what do you want me to do so you can forgive me?" Rudy asked calmly.

Rias fidgeted a little and said, "Kiss me."

"Uhh… I should have seen this coming."

Rudy didn't waste time and immediately kissed Rias on the lips.

"Are you happy?"

"You didn't let me finish. I was going to say 'Kiss me ten times'. And the earlier three kisses don't count," Rias stated while averting her gaze.

'What is this? Seriously, I am barely controlling myself from jumping on her, and she wants me to kiss her ten times? Kissing her was a bad idea, but how could I hold it after seeing her cute face.'

Rudy took a deep breath and pulled Rias close to him.

"Are you ready?" he asked.

"Who will count?"

"You do."

"I… maybe bad at counting," Rias said with a grin.

'Here it is. The Rias I know, who always know how to get on my nerves at the right time. Dammit! Why is she so cute?'

"Do you still want me to do the counting?" she asked with the same but a wider grin on her face.

"I will do the counting, thank you very much."

Rias wrapped her arms around Rudy's neck and stared into his eyes.

"I never knew your eyes were so beautiful."

"I have black-slash-brown eyes, and literally most humans in the human world have the same," Rudy remarked.

"I didn't mean the colors. I am talking about how beautiful your eyes are. I don't know why, but I can tell it has seen many happy and sad things. The color is so deep that it feels like I would fall into an abyss if I stared at them for too long. How can someone with such sad eyes smile like you do?"

Rias uttered all that one ago without pausing to even breathe.

"..." Rudy smiled at Rias and kissed her on the lips. He kissed her once, twice, and moved his hand to her waist.

He could feel her body and her chest rubbing against his body. Still, he continued kissing her. With each kiss, the duration between the two kisses became longer. It turned into long and deep kissing from simple and short kissing.

Rias had never felt the pleasure of a kiss before, and each and every kiss felt different than the last one. For some reason, Rias had a feeling that kissing Rudy more would make him happy, so she began to kiss him back.

Once the ten kisses were completed, Rudy made some distance between them and said, "Shall we go now?"

Rias reluctantly nodded and said, "Yes."

She wanted to kiss him more, but she couldn't ask for it.

Rudy grabbed Rias' hand and said, "Let's go."

"Where are we going?"

After a brief silence, Rudy answered, "Home."

They left the house, and Rudy asked Rias if she would like to teleport there or fly and Rias chose to fly.

They flew above the clouds, and Rias couldn't stop staring at Rudy with a confused yet curious look on her face.

"I should have asked this a long time ago, but… how are you flying without wings?"

"Magic."

Rias tried to overfly Rudy, but no matter how fast Rias flew, Rudy caught up to her in no time and didn't let her get ahead of him. She eventually got tired and stopped competing with Rudy.

They landed in front of the house, but Rias was still wondering why they would bring her to a house when she already had one.

It was morning time and Sunday, so Jessica and Rebecca were home.

"I know you have many questions, but you will know your answers soon."

Rudy held Rias' hand and walked towards the front door, which he opened using his powers without touching it.

"....!"

Rias had never been more confused before. And it was obvious since it was her first time seeing Rudy using his other powers.

Rudy entered the house, but Rias stopped at the doorway.

"What's wrong?"

"I cannot enter someone else's house without permission."

"Hmm? You don't have to be so formal. I am inviting you in."

"I can enter now because you gave me permission."

Rias stepped on her foot, but she was stopped by an invisible force.

"I… still can't enter."

'"Oh! Is this a vampire-related thing?"

"Yes."

"But you entered… oh, right," Rudy sighed and inwardly uttered, 'She must have been in our house before in 2008, and hence she entered without permission. And that 'before' is now.'

"Why can't I enter, though?" Rias wondered. "Does this house belong to you?"

"Well… no."

"Then call the one who owns this house."

"That would be our landlord, and I have no idea where they live."

After hearing voices, Rebecca came to check and saw Rudy and Rias at the doorway.

"Is this the girl who wanted to bring over?" Rebecca asked with a judging look on her face.
