Esper Harem in the Apocalypse

"My face? What's wrong with my face?"

Rudy turned to the side mirror of the car to see what Lilim was surprised about. However, before he could see himself, he had a sudden pain in his head.

"Argh." He even groaned in pain, which was rare for him as even after bearing unbearable pain many times, he had never shown a sign of pain on his face.

He grabbed his head in his hands and ran towards the forest.

"Hey! Are you okay?!" Lilim yelled and chased after Rudy.

She ran into the forest, but suddenly, a heavy wave of wind sent her flying to the car. Luckily, the car wasn't damaged as it was armored, but everything else was destroyed.

When Lilim looked back into the forest, all the trees were burned to ashes, and the ground had shattered completely.

"Daddy!"

Lilim rushed into the forest despite her fears. Her body was trembling, and her legs wouldn't stop shaking as she ran further into the woods.

After a while, she found Rudy sitting on his knees in the middle of nowhere. The upper part of the body was drooping to the ground while his hands were still over the part of his head.

"..."

She quietly made her way to him and asked, "Are you okay?"

"Yeah. But I feel like my head just exploded over a million times," he replied.

SIGH!

Lilim sighed in relief and said, "You will be—"

She once again stopped on her words and gulped down in fear.

"What's wrong?"

"Your face and head…." she muttered.

"Wait, don't tell me my eyes are bleeding again."

She shook her head and said, "It's…"

Rudy glanced around and noticed everything around him was destroyed.

"I did this?" he asked himself.

He immediately placed his hand on the ground and restored as much as he could. Then, he grabbed Lilim and made his way back to the car to see what was wrong with him.

He looked in the mirror and yelled, "What the— fuck?!"

He had grown horns on his forehead, which were similar to Lilim's but a bit better and bigger.

He touched them with a curious and confused look on his face and asked, "How did this happen?"

"..." Lilim had no words to say.

"Come to think of it, I did feel like something was emerging from my head." He turned to Lilim and asked, "Are they demon's horns?"

Lilim nodded in response without uttering a word.

"Hmm~" he hummed in wonder and said, "This is the second time my body is adapting…. mutating? Or perhaps evolving? What should I call it?"

'Wait, wait, wait. Wait a freaking second. I might be thinking too much, but this can't be just a coincidence. I had sex with Jane, who is a vampire— and because of that, I grew fangs like a vampire.

Now I had sex with a Lilim, who is a demon— and because of that, I grew horns? Humans don't have special traits, so I can't confirm anything about humans.

What about Angelica? She is a ghost, but I don't think having sex with her has affected me in any way. If anything, I provide her power through my cum, so she can manifest her form.

Hmm~ Why did I not think about this before? And if my theory is actually true, what's causing it? Is this dual cultivation? No.

After Nyxia mentioned dual cultivation, she gave me a book about it to read. I read the benefits and dangers of dual cultivation, and it was clearly mentioned that humans, vampires, and demons can't dual cultivate.

So how are my body features changing like this? It's surely because I fucked them, but how? I should ask Nyxia about this if we meet again next time.

Now putting everything aside, how do I…'

"How do I retract them?" Rudy asked calmly.

"Umm… just think about it?"

"..."

'I could control the fangs, so I should be able to control the horns too.'

Rudy tossed all the thoughts out and cleared his mind, but the scene of Lilim sucking his snake kept flashing before his eyes. And due to that, his horn between his legs woke up and poked Lilim's legs.

"...."

A few seconds later, his horn retracted, leaving no sign of anything on his face or head.

SIGH!

He sighed in relief and muttered, "Thank fuck, I am used to this."

Lilim squinted her eyes and pointed her gaze at his erect snake."If you can do that, why don't you do something about that too?" she remarked.

"That's… out of my control," he chuckled softly. "Anyway, I should leave now."

He wore his pants and patted Lilim on the head before saying, "Bye."

"Hmm."

"Actually, I can teleport you to the city if you want."

"The car has a tracking device, and it tracks all the movements. So I have to drive to my destination."

"What about the four hours we spend here?"

"I can just say the engine had malfunctioned," Lilim responded with a shrug.

"Oh, by the way, I told Maria everything about you being a demon and also that we were fucking while she was taking a bath."

After saying that, he teleported to his room, took a bath, had breakfast, and reached on time to pick Alice up.

Meanwhile, Lilim was driving the car with a dazed expression on her face. She was sweating after Rudy told her Maria was now aware of everything. She was afraid to face her, but for now, she had something else to do.

After driving for more than an hour, she reached Rudy's town and stopped in front of his house. She got out of the car and headed to the front door.

KNOCK! KNOCK!

After a few knocks, Rebecca opened the door slightly and asked, "Yes?"

Lilim rolled her eyes and said, "Can I come in?"

"Of course not! Who are you?!" Rebecca asked with a frowned face.

"Oh, come on. You don't remember me?" Lilim asked in disbelief.

Rebecca glanced around to make sure no one else was with Lilim.

"Are you some kind of salesman or a scammer?"

SIGH!

Lilim closed her eyes and changed to her demon form.

"What about now?"

"...Lilim?"
