I wake up early in the morning and start to think about yesterday. My father is a demon lord and mother a hero. I was summoned as a hero and now I'm the true demon lord. Kinda funny. I then remember, that I have to visit Lilian, to discuss our plan to take down the heroes. Because there is still time, before others wake up, I decided to make my plan.After two hour of thinking I finally finished the scheme. I think, that the heroes are back at the human kingdom, but I need to visit the kingdom to confirm it. As I was thinking about it, the girls had woken up and were stretching. Like always, I was enjoying the view. After stretching, they leaned in and gave me a kiss. After the kiss, we got up from the bed and got dressed. We went down and had our breakfast. After breakfast we went back to our room and I said:

"Hey girls. I'm going to visit demon lord today, so I will be away for some time."(Lucifer)

"Can we come with you Luc?"(Sariina)

I think about and answer:

"Sure. Why not."(Lucifer)

We put on our equipment and I see that Mia doesn't have any weapons.

"Hey Mia! Can you use any weapons?"(Lucifer)

"No onii-chan. I was never taught, but I can transform into a dragon."(Mia)

She says it with a cheerful voice. I nod to her answer and pat her head. Mia then leaves the room and says goodbye to Maria. Once she came back, I teleport us to the demon lords castle. We teleported in front of the castle and entered it. Once we were inside I shouted:

"Hey Lilian! I'm back!"(Lucifer)

Ten seconds later, she teleports in front of me, grabs my collar and says:

"Brat. Did you brought my books back?"(Lilian)

"Yeah, yeah! I brought them back."(Lucifer)

"Good. Is there anything else to discuss?"(Lilian)

"Yeah! About killing the heroes."(Lucifer)

She then looks me right in the eyes and,after a long pause,says:

"Okay! Let's talk about it in my office. You girls will follow my maid to the guest room."(Lilian)

After she says that, a maid comes to us and starts to lead the girls. Lilian then teleports us to her office and says:

"So tell me your plan."(Lilian)

"Sure. It's simple. I go to the human kingdom and confirm that the heroes are there. Once I confirmed it, I come back and take you with me. We then teleport to the castle and I use magic to gather the heroes in the throne room. Once they are there, we kill them."(Lucifer)

She has a lot of questions and I explain my plan in detail. This takes us a couple of hours to improve it and after we have finished it she says:

"That will work for us. We avoid unnecessary bloodshed with it."(Lilian)

"Yep! But remember: holy sword wielder is mine."(Lucifer)

"Yeah! I know."(Lilian)

"Okay! I'm going to the human kingdom tomorrow and confirm it. If they are there, we shall attack the day After tomorrow."(Lucifer)

She nods and I go to her library, to return her books. It takes me an hour to put back her books. I walk down the hall, when I hear moans coming from one of the rooms. I decide to enter, thinking it was my girls. I was wrong. They were girls, for certain, but not those whom I expected.It was Lilian and Nyx. Nyx was laying on the bed, while Lilian was playing with her. I stand there, while blinking my eyes. Lilian looks at me and says:

"Wanna join in the fun?"(Lilian)

"Maybe. But why is Nyx here?"(Lucifer)

"Ooh! You know her?"(Lilian)

"Yep! She's my stalker."(Lucifer)

I say it with a smile. Lilian looks at me and says:

"Good to know. Anyways this little girl got too close here and I took her."(Lilian)

"I understand. Be gentle with her. It's her first time."(Lucifer)

"How did you know?"(Nyx)

She says it with a completely red face. I smirk and say:

"I didn't."(Lucifer)

Her face goes even more red as she just said, that she was a virgin. Lilian has a perveted smile now. She looks at me and says:

"Come join us Lucifer. I want to see what the true demon lord can do in bed."(Lilian)

"Okay! I'll join, but I will bring my girls too."(Lucifer)

Lilian face smiles even more and I go look for my girls. After I found them, I tell them about it and they agree. I then teleport us to Lilians room and I see that Lilian and Nyx are already naked. We then take off our clothes and I push the girls on the bed. Lilian and Nyx look at me and say:

"This thing is going inside me? It won't fit."(Nyx)

"Big."(Lilian)

She says that, while drooling. I then move to Nyx and move my hand down to her vagina.

"Hii!"(Nyx)

She's already wet, because of Lilian. Nyx looks at me and says:

"Will you take responsibility?"

I nod and then I slowly move my penis into her vagina. As I have inserted a little, I could see, that she felt pain.

"It hurts, but it feels good at the same time."(Nyx)

She says that with a face full of ectasy. I then insert my penis fully into her and start to move my waist. While doing that, I pull Lilian with my free hand and start to play with her huge boobs. She leans in and kisses me. While she is kissing me, I move my hand down to her vagina and start to finger her. While we were doing that, the twins started to play with Nyxs boobs and Sariina and Mia came next to me and pulled my head into their kiss. I keep thrusting for some time when Nyx screams:

"I'm cumming!"

She then cums and I follow her. Her face is full of pleasure. Then Lilian pushes me down and sits on top of me.

"I like to be on top."(Lilian)

She then put my penis into her vagina and I saw drops of blood. I smirk and say:

"So you were a virgin too."(Lucifer)

"Shut up."(Lilian)

She says that and start to move herself up and down. She leans, while doing that and kisses me. While she is doing that, I used my free hands and pulled the twins into my embrace. After Lilian stops kissing me, I start to kiss the twins. We continue it for some time and I cum with Lilian at the same time. Lilian comes off of my penis and lays down. Then Mia says:

"Me next onii-chan!"(Mia)

I then hug her and insert my penis into her. Because we are doing it in a sitting position, Mia start to move her waist and I kiss her the same time. Mia keeps moving her waist and she cums a couple of times till I cum. I then move onto the twins. Sara is laying on the bed and Kara is on top of her. I start with Sara and then move onto Kara. I then start to fuck Sariina and we keep going for some time. We both cum at the same time. I look at all of the girls and smile. I then say:

"Night is still young."
