A Hentai System in the World of Danmachi.

Chapter 160 – Someone’s moaning in pain. +18 (Tiona’s POV)

*Tiona's POV*

I woke up suddenly, hearing some strange sounds. It sounded like someone was in pain. I looked at the bed where Tione was supposed to be sleeping, but I didn't see her there, so I started to worry.

I trusted Tione. I knew she was strong, but I was still worried.

'And it sounds like a woman.'

The sounds were moans. They sounded like the moans of someone in pain because they were loud and grotesque.

"Tione?" I called her name when I reached the corridor.

When I came out, I looked at the door to Ais's room.

"Isn't she listening to this? I'm sure she's awake, why isn't she worried about those sounds?"

The sounds started to get quieter as if they had been drowned out by something.

The only thing I could imagine was someone covering the mouth of the woman who was moaning so that no one would hear.

Is she being murdered?

I walked to the door opposite my room, where the moans came from. As soon as I approached the door and put my ear to it, I could hear what was going on inside much better.

In addition to the moans of pain, I could hear noises similar to slaps or punches.

Plap~~

Plap~~

Plap~~

I tried to open the door. Of course, the door is locked.

I need to know what's going on in there. 

Tione...

I started to get more and more nervous. I ran down the stairs and over to the room's window where it was happening. I looked around for somewhere I could climb up to look inside the bedroom.

There were a few buildings around. I can do this.

I climbed up a lower building and then jumped down to the building next to the inn. 

I could see part of the room—the bed and a leg. Although it was dark, I could tell it was a woman's leg—a tanned leg, the same color as mine.

The leg was in a strange position as if the person in question was lying down with her legs open.

Images began to flash through my mind, and my body felt hot.

'Could it be...'

I jumped into the inn building and climbed down the walls until I reached the window. It was a little harder than I expected, but it worked. Luckily, no one was around, so I wasn't seen.

When I got to the window, the moaning sounds got louder.

MmMmMMmm

mMMMM

MmMMmmM

The sounds of "slaps" and "punches" also got louder.

Plap!

Plap!

Plap!

However, contrary to what I expected, it was nothing of the sort.

There she was, Tione. She was lying on the bed, completely naked and with her legs wide open. Right above her, Luan was kissing her while moving his hips wildly, penetrating his huge thing inside Tione.

I was speechless for a moment.

'Since when do you two have this kind of relationship? I had no idea...' And Tione knows that Ais likes Luan, so why did she get into a relationship with him? Tione likes him... and I didn't notice.

Even I like him a bit... But I wouldn't betray Ais like that. Ais is completely in love with him.

'But this is incredible. How is that thing getting inside that hole? It's so small...' I had a perfect view of where the two were connected. Luan's thing is too big.

I can't imagine something that size going inside my pussy.

I swallowed my saliva as I watched them.

I was in an uncomfortable position, but I still managed to get my hand inside my shorts and started touching my pussy as I watched the two of them. If anyone saw me now, they'd call me a disgusting pervert.

'But I can't stand it. It's the first time I've seen something like this.

As I watched Luan fuck my sister's pussy ferociously, I masturbated until I came, wetting my panties and shorts.

####

*Luan's POV*

I was fucking Tione's pussy waiting for the mission complete notification to arrive.

But the notification I got wasn't what I was expecting.

[ Mission failed! ]

When I read the notification, I started to get nervous. However, I finally felt it. Someone's presence was at our bedroom window. I'd forgotten to close the curtains.

And the person there was Tiona.

I could tell because of her presence.

I clicked my tongue but continued to fuck Tione's pussy. The mission has already failed, and I can no longer go back in time with my skill since the cooldown is a full week. That's it... this mission was a failure.

At least I managed to have sex with Tione.

That's a big step.

'I just have to get Tione addicted to my cock and fall in love with me so she can be added to my harem.'

Tiona continued to watch us for long minutes until I received another notification from the system.

[ Tiona is scared and horny after discovering your relationship with her sister! ]

[ Get Tiona to join in this complicated relationship. ]

[ Reward: 300 points. ]

'The missions have started to offer more and more points. Ais's mission is 500 points and this one is 300 points. Together, they'll give me 800 points, that's incredible.'

[ Warning! If Ais discovers the relationship between the three of you before her mission is completed, both missions will fail, and you will receive a severe punishment! ]

What the hell? This is the first time the system has talked about a punishment.

I can't let Ais find out about this.

I kissed Tione's lips to stop her moaning even more. I don't want Ais to come here like Tiona.

'I hope Tiona's enjoying the show. She's next on my list.'
