Sin System: Demonic Harem After Reincarnation

''Kya!'' Ria suddenly woke up and looked around.

Her blurry gaze adjusted to the bright light of this chamber. She meant to press the bedding with her palm but sensed a warm forehead. It was Charlotte, Viscount Dorstone's biological daughter, one year older than her.

''Charlotte, Charlotte!'' Ria shook her sister. However, she didn't wake up.

The wolf girl then realized her hands were tied with a weird black chain.

''I can't… seem to channel mana.'' Ria frowned. She got up from the bed and looked around. This was a large room but there were no windows. The only exit out of here was the tall door which appeared locked.

Ria remembered she was captured by that terrifying human. It appeared he brought her as well as Charlotte here, but where was this place?

She walked around, feeling the walls and sniffing the air. As a beastkin, her sense of smell was high. She was an actual wolf who could transform into a human form. Something only shifters of the 2nd Circle or higher could do.

''It smells… like blood and monsters…'' she scrunched her nose.

Behind her, Charlotte stirred. The moment she woke up, she screamed. It took her a few seconds to realize that there was no one here except for her sister.

''Ria!'' Charlotte slipped from the bed and ran behind the wolf girl. She grabbed Ria's top and looked around with her green eyes.

''W-Where are we?''

The blonde-haired teenage girl was extremely sheltered and pampered. Despite being a year older, she was like a younger sister to Ria.

''I don't know…'' Ria walked forward and Charlotte clung to her.

''Eh?''

''What?''

Both girls suddenly realized that they were not wearing their previous costumes. Instead, they wore these otherworldly clothes which showed most of their skins.

Ria wore jean shorts and a top which barely reached below her breasts. Charlotte wore a miniskirt and a white cotton T-shirt. Underneath those, they wore silk panties and soft bras.

Amelia and Riri had dressed them like that at Jake's orders while the two girls were unconscious. Before he left the dungeon to advance, Jake wanted to have some fun.

He was inside the core chamber, sensing these two girls with his authority as the dungeon master.

'What are these weird clothes? Who dressed us?'

Inside the room, the girls pulled on their clothing. They also secretly touched their little flowers and breasts, suddenly aware of the underwear.

''Uhm…'' Charlotte fidgeted.

''What happened?'' Ria asked.

''N-Nothing…'' Charlotte was feeling tight around her chest. The bra was one cup size smaller for her.

As she was wearing a gown and had a cloth tied around her breasts, Jake had mistaken her cup size for B instead of C.

However, now was not the time to complain. They had to escape from here. Charlotte knew she troubled Ria a lot and didn't tell her sister about it.

''It's locked…'' She drew Ria's attention toward the urgent situation.

Charlotte was worried about her parents. She wanted to go home quickly.

''You can use your magic to open it, right?'' The nobleman's daughter asked the wolf girl.

''I-I can't seem to use magic. These chains are obstructing the mana flow.'' Ria's fluffy tail fell as she replied, gritting her teeth. She was trying to break the Mana-sealing Chains but her strength was barely above 170. It wasn't enough.

Charlotte's face paled. Seeing it, Ria smiled and said, ''Don't worry, I'll find a way.''

She walked forward and touched the door. It seemed to be made of steel. Ria lifted her tied hands and pushed it. To her surprise, the door creaked and opened. It only looked like it was locked.

Behind her, Charlotte's eyes widened. The girl was like an excited butterfly as she exited the room with her sister.

''Shhh.'' Ria lifted the wolf ears on her head. The chamber was dark and Charlotte couldn't see her sister's violet hair. However, her chocolate brown eyes glowed. She had night vision as well.

Ria looked left and right and pulled Charlotte. They ran through the dark corridor. Turning left, they saw green fire torches on the walls. Ria looked to the left and saw that it was dark.

''This way!'' She again pulled her sister's hand, going right. If they had gone in the left direction, they would have reached the underground river.

Inside his chamber, Jake chuckled in amusement. This floor was the largest, and they were heading to the place where the Hell Knight stayed.

Tap… Tap… Tap… The tight flesh on the girls' thighs trembled as they ran while holding hands.

A staircase suddenly appeared which led a little higher. Ria had already deduced that they were in some sort of underground basement. She didn't hesitate to climb the stairs.

Charlotte passively followed the wolf girl. She had no sense of direction. If not for Ria, she would've already lost herself in this place.

The moment the two girls stepped on the higher ground, they appeared in a large hall-room.

''Aaaa!'' Charlotte cried seeing an eight-feet-tall, terrifying giant standing motionlessly in the middle.

The wolf girl thought it was a statue at first. But when the Hell Knight turned its head around, alarms rang in her mind. She instinctively turned around and pulled her sister.

She had never seen such a terrifying monster in her life. Charlotte's heart was beating and tears were about to drop from her eyes.

''What was that?! W-Where is this place? Ria!'' She looked behind and ran as fast as she could.

They were barefooted and running on the hard stone corridor hurt their soles. However, the girls were feeling a rush of adrenaline and didn't notice it.

They both kept turning the corners, not realizing they were going closer and closer to the demon's abode.

Jake stood up from his chair at this moment. Lena had her eyes closed. She could somewhat visualize the two girls. They had just gotten a scare from a guard imp.

'Let them in.' Jake transmitted his will to his monster servant while smiling.

Lena opened her eyes at this moment and giggled. She was the one who kept igniting and extinguishing the torches on the corridors.

Ria sensibly followed the lit torches and avoided the dark corridors. That's how the two girls found their way to the dungeon's core area.
