The Demon King Who Was Supposed to Lose Ended Up Defeating the Targets, and Now the Heroine Has Been Sent as a Sacrifice - Chapter 15

Chapter 15: The Demon King Supposed to Lose, Drugs the Yandere Little Sister

“Diablo, is something wrong?”

After our welcome-home fun ended and Elsia fell asleep using my arm as a pillow, Mana suddenly asked this.

I tilted my head in confusion.

“Why do you ask?”

“Because today, you two were incredibly lovey-dovey.”

“Oh, sorry. I didn’t mean to neglect you, Mana.”

It’s true that I might have enjoyed Elsia’s body for a longer time today.

“Oh, no, no, that’s not it. I’m not blaming you. In fact, I’m always satisfied.”

“Really? Are you sure I’m not overdoing it?”

Oh no. I’m suddenly feeling anxious.

Even in the closest of marriages, dissatisfaction with the nighttime activities isn’t good.

When I said this, Mana smiled awkwardly and pressed her huge breasts against me.

“My goodness… Mama would never lie. I’m truly not dissatisfied with you.”

While caressing my body, Mana whispered into my ear.

A sweet, mature woman’s scent wafted over me.

“I’ve always had a very strong sex drive. With my late husband, I could never fully satisfy it. But you’re different, Diablo.”

“Oh, really?”

“Fufu, yes. I’m not saying anything bad about him, but you have a very strong sex drive. My daughter and I are happy to be your wives.”

“…If that’s the case, I’m glad.”

Then why did she ask that question earlier?

“Elsia was really wild today. You were like an animal, so I wondered if something had happened. You know, as a mother, I’m curious about my daughter’s relationship.”

“Oh, I see… Well, where should I start?”

It seemed Mana noticed the change in us and was genuinely curious. She was concerned about her daughter’s relationship.

I hesitated on how to explain and then told Mana what happened yesterday.

“Elsia confessed to me again. She was so cute at that moment.”

“Oh my, my daughter has always been cute.”

“I know. But after her confession, she looked even cuter, and I got really intense. I hope she doesn’t hate me for being so selfish.”

“Fufu, look at Elsia’s sleeping face. She looks content. You don’t need to worry.”

I glanced at Elsia sleeping in my arms and saw that she indeed seemed content.

Mana smiled warmly.

“By the way, Mama loves you too, Diablo.”

“Is that really okay?”

“Ufufu, yes. I still love my late husband, but now, I love you the most. So, please continue to cherish my daughter and me, okay?”

I couldn’t resist her unexpected words, and making sure not to wake Elsia, we made love passionately.

However, Elsia woke up midway and joined in.

She couldn’t stand that Mana and I were having fun without her, so she eagerly sought kisses and my demonic sword like a hungry little bird.

We’ve had mother-daughter threesomes many times, but today we were especially intense.

Thank you for the meal.

As I was basking in the afterglow of our lovemaking, Elsia spoke to me seriously.

“Lord Diablo, I have a favor to ask.”

“What is it? Tell me.”

I listened to Elsia’s request, momentarily confused and unsure of her meaning.

“Well, I don’t mind, but… is it okay with you two?”

“It’s for revenge.”

“If Elsia is fine with it, then so am I. In fact, I’m excited for other girls to experience how wonderful you are, Diablo.”

It seemed there was no issue.

To fulfill Elsia’s request, I headed alone to the underground dungeon of the Demon King Castle, where a certain person was imprisoned.

That person was the girl I captured alive at Avan Castle.

Misha von Avan.

“Ohh, things have gotten really bad overnight.”

The underground of the Demon King Castle had a terrible smell.

A rotten stench lingered heavily in the air, sticking to my nose.

At the back of the dungeon, where I didn’t want to stay long, Misha was lying in complete darkness, severely injured.

Since last night, Misha had been subjected to unimaginable torture under Elsia’s orders.

There was no light in her eyes, and she was barely breathing, looking as if she could die at any moment.

“Are you okay?”

“…”

I tried calling out to her, but there was no response.

I opened the dungeon door and went inside to check on Misha’s condition.

Whoever was in charge of her torture had shown no mercy.

Her bones were broken, and she was covered in painful-looking bruises.

The fact that the one who ordered this, and who adorably moans during our intimate moments, was Elsia, is the scariest part of all.

“Right, first I need to heal her.”

I used an item I had found in a treasure chest while exploring dungeons.

It was an Elixir, a universal healing potion.

In the adventurer part of ‘The Saintess and the Five Heroes,’ you get a ridiculous amount of these magical items near the end, and consuming one heals all injuries completely.

For someone like me, who can’t use healing magic while dungeon exploration, it was invaluable.

I gave Misha a few drops of the Elixir, and her injuries healed rapidly, returning her to perfect health.

Misha then regained consciousness.

“Ugh, where… am I…?”

“You’re awake. This is the Demon King Castle.”

Hearing “Demon King Castle,” Misha’s eyes widened in fear, and she started trembling.

“No, please don’t come near me, don’t hurt me! I’ll do whatever you say!! Please stop hurting me!!”

“Calm down. I won’t hurt you anymore.”

“R-Really? You won’t hurt me anymore?”

For some reason, my heart was pounding.

Maybe I got excited seeing a girl in such a terrified state.

She must have been through a lot because she didn’t seem to recognize that I was the one who captured her at Avan Castle.

No, this isn’t right.

“It’s true. I will take responsibility for you. Drink this; it will make you feel better.”

“…Okay.”

I handed Misha a small bottle filled with liquid. She hesitantly drank its contents.

“Feeling better?”

“…Thank you.”

“Good.”

Misha nodded reluctantly.

In the game, she reacted similarly when Elsia spoke to her.

“…What will happen to me?”

“Nothing much. You won’t have your freedom, but you won’t be tortured anymore.”

“I’ll be kept in this dungeon forever?”

“Hmm. I can give you a room. You won’t be allowed to leave, so it would be more like house arrest.”

“…I understand. Ah… ugh?”

Misha began to struggle.

Her breathing became erratic, her face turned red, and she fidgeted, trying to close her white thighs.

I pretended to be concerned and spoke to her.

“What’s wrong? Are you feeling unwell?”

“N-No, it’s nothing… stay away!”

I knew exactly what was causing her discomfort.

The liquid I gave her after the Elixir was an aphrodisiac made from the body fluids of a succubus.

Even a single drop can make someone amorous for three days and nights without stopping.

After drinking it, even someone uninterested would become eager and ready for intimate activities.

It also acts as a nutritional supplement, so no food or water is needed until the effects wear off.

You can buy this super lusty potion cheaply at the Castle’s shop.

“Let’s move to your room.”

“No, don’t touch me…♡”

Despite her protests, I forced Misha to stand and led her out of the dungeon. 

She was dripping wet, leaving a trail on the hallway floor of the castle.

Misha clung to my arm, trembling, unable to put strength in her legs.

…She’s so cute.

In the game, she was a yandere little sister who tried to get rid of anyone close to her brother, but seeing her like this made me want to tease her.

“We’re here. This is your room.”

“Ah, uh…♡”

We arrived at the room, but Misha didn’t want to let go of me.

I glanced at her face and saw she had a lustful look, staring intently at the demonic sword between my legs, clearly wanting it.

I pushed Misha onto the bed.

Although I had Elsia and Mana’s permission, holding a girl around thirteen or fourteen like Misha felt somewhat wrong…

Will things go as Elsia planned?

With these thoughts in mind, I enjoyed Misha thoroughly.
