Esper Harem in the Apocalypse

A few minutes passed since Rudy and Ruby started dancing alone in the party hall. It was a soft song and a slow dance, while their movements were even slower.

Rudy had his hand around Ruby's waist, and his other hand was holding her hand. Ruby's hand was on Rudy's shoulder, and they were dancing in the same pattern again and again.

"So… how long are we going to dance like this?" Ruby asked in a low voice, lower than the soft song.

"You don't like it?"

"Just answer my question." Ruby dodged Rudy's question.

"We will continue until you are satisfied."

"I am satisfied."

"No, you are not."

"How do you know? It's not like you can feel what I…" Ruby sighed without finishing her sentence.

"You have the power to do that too?" She squinted her eyes and asked with a judging look on her face.

"Yup."

"Argh!"

"I can feel what you feel."

"That's a creepy way to put it. Please, never say it again."

"While I am at it, I should also mention that I can hear your thoughts as long as I am touching you," he uttered with a grin.

"What else can you do while touching me?"

"Everything, actually."

"I better be careful the next time I let you touch me."

"Touch you? Why would you make it lewd for no reason."

"Your mind is lewd. And hey, if you can feel what I feel and hear my thoughts, doesn't that mean you already know everything about me?"

Rudy shrugged without answering.

"Then why would you ask me questions if you know everything already?"

"To make you say it, and realize it, so you can be honest with yourself."

"Or you just like teasing innocent girls."

"Heh!" Rudy chuckled softly. "You are not innocent, baby."

"Don't call me that. I am not your baby!"

"What about Sissy? You are my sister, in a way."

"Just call me Mia, please."

"How about you call me something else too? I am sure you also find it awkward to call me Rudy… wait, have you ever actually called me by my name?"

"Then it's settled. I will call you bro if you call me sissy."

"Hmm~" Rudy hummed in amusement and smirked, "I would prefer if you called me big brother instead."

"Bleh!" Ruby slipped her tongue between her lips.

"I just heard your thought, which said, 'I always wanted a big brother'. Now that's cute, what do you say?" he smirked.

"Yes, I indeed had that thought, but I don't want 'you' as my big brother. Because that would mean Maria is your little sister, and you are having an intimate relationship with her. That would be no different than what my dad and aunt did."

"Come to think of it, I never asked what you thought about their relationship. Do you find it disgusting?" he asked with a curious look on his face.

"I don't know, honestly. Like… Maria and I grew up together, and I always saw her as my sister rather than my aunt, so when I found out that she was actually my sister… I was… somewhat happy.

At that time, I had no idea what incest was or what dad and aunt were doing was wrong. If I had been taught that it was normal, I would have considered it normal. I didn't know what was right and what was wrong.

So… what I want to say is that I am happy that Maria is my blood-related sister, but I don't have any comments about dad and aunt's relationship. I wonder why they chose to do it… or what forced them to…"

"The answer is lust."

"Argh! I can't believe we are having this conversation while dancing. Change the topic, please."

"Alright." Rudy looked into Ruby's eyes and increased the dancing speed.

"I asked you to change the topic, not to increase our dancing speed."

"You are demanding as fuck, do you know it?"

"That's my charm, then."

"Is that so?" Rudy raised his brow with a cheeky smile and slowly moved his hand from Ruby's waist to her hips.

"...!"

He then squeezed it a little with a grin on his face.

Ruby widened her eyes and glared at Rudy.

"Take. Your. Hand. Off. My. Ass!"

Rudy removed his hand and said, "Your ass is so perfectly designed that my hands accidentally slipped to appreciate the art."

"That's the most ridiculous thing I have ever heard coming from your mouth," she said with a knowing look on her face. "And if you don't know it, that's considered sexual harassment."

"Well, you are the one who asked me to change the topic. If you want, you can touch me too."

"Hah?" Ruby chuckled and asked, "What am I supposed to touch? Your dick? No thanks. When I saw it, it was so big that it wouldn't fit five of my hands."

"It's not that big. Please, don't ever say it to someone else, or they would be genuinely scared of Mister Dick and me."

"But I have read that penis size increases to double when it's hard. And when I saw yours, it wasn't hard, and it was… big."

"At that time, I was simply limp, not small."

SIGH!

"I just realized we are having a conversation about dick while dancing. Why do you always come to such dirty topics and ruin the moment?" she asked with a flustered face.

"How is everything that happens my fault? You should learn to take the blame, or your boyfriend will dump you."

"Thanks for worrying, but fortunately, I don't plan to get a boyfriend."

"That's sad. Do you plan to stay single all your life? You are missing out, gurl."

Ruby squinted her eyes and shook her head while staring at Rudy.

"You can feel my emotions and hear my thoughts, still… you are doing all this to me. Do you like torturing me?"

"How mean, I am just worried about you like any brother would for his sister-in-law."

"You are worrying about useless things. You should worry more about what you would do if I ended up falling in love with you."
