Sin System: Demonic Harem After Reincarnation

''Hah… Hah…''

Yunna was lying on her master's bed, who lay on top of her. Her silky red hair was spread all over the pillow. She was gasping, feeling her master's lips on her nipple.

Jake had pinned the succubus beneath him while sucking on her left breast. He possessively grabbed her right one and squeezed it.

Yunna relaxed her legs and gently stroked the back of Jake's head. He was drinking her milk, and that somehow calmed her overpowering lust. Her motherly nature took over and Yunna got into a side lying position.

Jake kept sucking her nipple like a hungry baby. Yunna's milk was really tasty. His other hand pulled her waist closer. Jake put his thigh over her thighs and grabbed her buttock, gently kneading it.

After giving birth, Yunna's hips and breasts had grown larger. In a sexual context, her figure had more appeal to him now because she looked extremely fertile at a glance. This applied to all other women who had given birth.

''Mmm…''

Jake didn't switch to another breast and instead began kissing his succubus. He didn't plan to fuck her yet even though he was hard.

Yunna would take at least another two weeks to fully heal. Sucking on her breast seemed to calm her down, so Jake would just do that until her pussy was ready for some pounding again.

However, there were still a lot of things she could do other than direct penetration.

''Master, I want to suck too…'' she whispered into his ear and Jake smiled.

A while later, Jake was sitting on the edge of the bed, looking at the amount of his Evil Points while Yunna sat below him, slurping on his cock.

Her milk bags jiggled back and forth while she moved her upper body. Yunna pressed her palms on her master's pelvis, obediently sucking on his meaty rod to make him cum. Her feet were up, and her ass moved left and right.

After getting pregnant, she was worried that her master might not find her likable. Yunna was glad that was not the case.

'Looks like I can buy a lot of things now…' Jake thought.

[Evil Points: 221,397]

Currently, there weren't enough monsters in his dungeon. After advancing to Tier 2, the space inside was huge. The lower the floors, the larger their area. The 66th Floor was large enough to house a large hill.

His palace was just a structure among the various chambers and tunnels and even then, it was huge.

Jake could literally build cities on all floors beneath the 45th. By filling all floors, tens of thousands of monsters could be kept.

The dungeon wasn't the small seven-floor hole like it was previously. The monsters outside weren't enough.

''Mrrnnhh~ Mnnghh~''

Dismissing the status panel, Jake stood up and grabbed one of Yunna's horns. He fucked her tight lips for some time and came inside her mouth.

Yunna closed her eyes and drank his semen. He slipped out his rod midway as he was in a hurry and shot the rest of it on her face.

''Go wash yourself.'' Jake patted her and went out of his room, buttoning his pants.

'Lena, come with me,' he called the Dungeon Fairy through his special connection with her.

Hearing the voice on her left ear, Lena quickly flew to the place where her master was going toward. She met him midway outside of a guest chamber from where one normally exited the underground palace.

Jake quickly took flight and flew higher. Lena followed him.

''What are we going to do, master?'' She asked, flying beside him.

''I need to create an ecosystem for this dungeon, you know how to distribute monsters across all floors, right?''

''Of course, leave this to me, master!'' Lena fluttered her wings faster and squeaked in a cute voice.

He looked at her once and suddenly grabbed her head, flying faster. Lena cried as Jake increased his speed by three times.

A hole appeared in the ceiling and they passed through it, appearing on the 65th floor.

Minerva, who was training her new battalion of Undead Knights, was surprised as she sensed Jake. She commanded the undead to remain on standby and flew toward the horned demon.

Minerva curiously glanced at Lena. Jake would usually shoo her away, yet he was together with her today.

''Master is going to make monsters appear again!'' Of course, she couldn't keep her mouth shut and blurted this out before Minerva even asked.

''Make monsters appear?'' The necromancer was confused.

''It's his magic- Ah!''

Jake caught the little fairy and spanked her. She made fake, pitiful cries but started actually crying when he hit her harder.

''Sniff… Sniff…''

Paying no attention to Lena, Minerva asked a question. ''Are you also a summoner?''

''Well, that's one way to put it…'' Jake agreed in a dodgy manner.

''I see, why do you need monsters?''

He then told her about filling the floors with more monsters and creating an ecosystem. These days, more and more adventurers had been visiting his dungeon.

Most were disappointed by the lack of treasures and monsters. Even though it was a Tier 2 Dungeon, they could easily go past ten floors in a week. This decreased the appeal of his dungeon and made adventurers less likely to explore deeper. Jake didn't want that to happen.

''That's why I brought this troublesome pest.'' He pulled Lena's chubby chin, and she flew away, leaving a trail of pixie dust.

Potion makers would go absolutely mad if they found out that such a valuable material was being wasted. Lena had no idea how desperate some mages would be for a pinch of dust on her translucent wings.

''I think I know about dungeon ecosystems,'' Minerva said, rolling a strand of her hair. ''You see, I've been to a lot of dungeons. Not just in Grimbow, but other kingdoms as well. Have you heard of the Allied States?''

''No.'' Jake shook his head, replying in a deep voice.

''You should look at the map of our continent once.'' Minerva waved her hand, making her undead burrow underground.

She continued, ''There is a Tier 3 Dungeon called The Whispering Labyrinth in the Allied States of Ourin. I once reached the 74th floor of that dungeon. If you can summon any monster, I know a way to replicate the ecosystem in dungeons I've been to. How about giving it a try?''

Jake thought for some time. He even opened the system shop and looked through the species of monsters available. There were thousands of plants and monster species, so it should be possible to replicate an ecosystem.

He didn't have any desire to make it unique currently. He just wanted a running ecosystem for his dungeon. Copying another one would lessen the chances of him messing things up and wasting his amassed Evil Points.

With time, as he added more monsters, the habitat for monsters would definitely become different from the ones he had copied, and thus gaining uniqueness.

''Alright, come with me.'' Jake brought Minerva as well and ascended the floors.
