"I-I'll take this one!"

A few moments later, with a smile on her face, Hazuki brought him a slender red collar.

It had a thin enough lead that it could be torn off if she resisted.

Mars felt a little guilty as he sensed the girl's taste in Hazuki's choice.

――I feel so immoral when I think of her as someone's daughter. ......

A collar ...... on a child who would have been cherished, Lilia was sold into slavery, but Hazuki-chan, because she voluntarily .......

I feel a little guilty for violating human rights, and a little excited.

"――I'm going to make you happy. I hope that you won't have any regrets, Hazuki-chan. I hope that in the future you will feel that this day was not a mistake."

"……? Yes, ...... I don't regret much, you know? I can't stop thinking about every mistake I make. I'm sure I've made a lot mistakes, but that's why I'm here now. It's so lonely to be wrong about everything you don't like."

"Lonely. ...... Yeah, ...... It's lonely."

――Can you even say something serious? ...... That's the word I didn't want to be told.

Mars chews lightly on the inside of his mouth, not changing his face.

I know. It's not a problem that can be divided easily, even if you know it.

It's something I've regretted for a long time, to the point of taking my own life.

"Now, put on your collar and kneel before your master. That is the proper attitude for the future."

Lilia wrapped herself in a blanket and said in a cold voice to Hazuki from her bed.

"Eh, it's so hard to put this on myself. ...... P-Please put it on me, Mars-san. ......―P-Please make me your slave. ......"

"Hmm ......, that's erotic ......, come here then."

Hazuki settled between Mars' legs and turned around.

In front of her was Mars' cock, and it was a little embarrassing to stare at it.

The idea of standing on his cock was too sexual for Hazuki.

――I knew it, it's big……I wonder if it's going in my inside.……I'm starting to get itchy.……。

Hazuki bowed her head slightly as she waited for Mars to wrap the collar around her.

"Nnn!……"

"Are you weak in the neck? Lilia's weak too, but I guess girls are like that."

When Mars touched Hazuki's thin neck to wrap the collar around her, she let out a short squeal.

Although Hazuki's hair was not long, he had to roll it up by hand or it would get caught in the collar.

"It's kind of sneaky ......, but I don't think anything of it when I touch myself ......."

"It would be so. It would be a problem if you could feel every single thing just by touching it yourself."

Lilia did not break her condescending stare at Hazuki.

It was a very personal feeling.

"I got it wound up. ――It's really good, isn't it?"

"Y-Yes ... I belong to Mars-san now. It's bad for X-Xerius, but ... I want Mars-san..."

Turning around, Hazuki looked at Mars.

There was no darkness in the eyes that stared at him.

"Master, do you remember the chanting of the slave magic? I'll do the magic myself, but Mars will have to say the words."

"Let me see, ...... Thou shalt be the sword and shield of the Lord and swear to obey until the end of his life?."

"Yes."

Mars remembers when he signed the contract with Lilia.

"It sounds like a wedding line."

What he thought came directly out of his mouth.

Magic is activated by a third party, and a contract is made based on the will of both parties.

In this case, Lilia was the initiator of the magic.

The contract of slavery is made like a vow of love in front of a priest in a church.

"I'm a little embarrassed that you would say that if you were ....... It's not my place to say it."

"I've heard more embarrassing looks and lines from Hazuki-chan. ......"

He even watches her masturbate, so he doesn't think he's ashamed of this line.

"Then again. ――Thou shalt be the sword and shield of the Lord and swear to obey until the end of his life?

"I swear it."

――Immediate answer.

Basically, she's just honest, or rather, she's just too honest, isn't she?

A number of new lines emerge on the slave crest on Mars' left hand.

It's a sign that Hazuki has become his slave.

To the casual observer, he's probably a rugged tattooed man. "I can't go into the public bathrooms," Mars says, staring at the back of his left hand, realizing that he now has more slaves.

"Hmm, ......, uh, is that it?"

"That's right. It doesn't really change anything, does it? Ah, But the collar can't be removed by Hazuki-chan will, and if I activate the slave crest, I can twist your will. I don't use it ......, though."

"Y-yes, ......, Th-then, will you mate with me, ......?"

Sitting on the floor, Hazuki was looking at Mars' cock with greedy eyes.

The changing emotions were interesting to watch, but also made Mars uneasy.

――Unlike Lilia, Hazuki-chan is likely to use a slave crest .......

"So that's it. You're lewd.――Sorry for the backtracking, but I have a condition for the show."

"Co-condition ......? You promised me that if I became a slave, you would make out with me, make love to me, and mate with me all day long. ......"

Hazuki pinched all the fingers of her own hands together and pointed the tip of her mouth.

"――I didn't. No, I didn't right?"

"No, you didn't. It must be a delusion born in this lascivious woman. She's been masturbating for so long that she's lost her mind."

Lilia's words were laced with contempt, but in a way they were closer to the truth.

In Hazuki's fantasies, Mars was in heat with herself and would mate with her all day long.

Since she had been having these fantasies ever since they met, Hazuki's perception of the real Mars was a bit detached from her own.

She saw things in a convenient way.

For Hazuki, Mars was like a symbol of sex.

Rather than love, it was a relationship of interest.

At this stage in her life, she only liked the element of Mars.

If she needed to become a slave to get it, she would do it.

"Huh? ――T-that's right, maybe. ...... Ma-Mars-san inside of me is always saying how cute and adorable me is and mating with me. ...... Yes, I've never mated with him before.……――huh?"

"Are you serious saying that ......? Have you already been mentally contaminated by someone......?"

He didn't know there was a child who could make so many assumptions. ...... Mars felt scared by Hazuki's crazy thoughts.

"Isn't she polluting her own mind? ――For now, kneel before your master. Put your three fingers together and bow your head and hang your head. The same disrespectful attitude as before will not be tolerated in the future. I will teach you the attitude and manners of a slave. You seem to have an unusual obsession with mating, but you will not be allowed to nip another man in the mouth. Also, please call it 'sex' or 'Ecchi' instead of 'mating'. Ecchi sounds cute, so it's mine. You should call it sex."

"It-it's okay! No one's has dick is bigger than Mars-san, you know! It's sex, sex, right?! I totally get it!"

Mars and Lilia both looked at Hazuki with indescribable expressions.

Even the gentle Mars can't help but laugh.

――She choose a man by his size, and this girl is .......

By the standards of this world, it's a cheat. ......

"――Damn it, you pervert. Is that all you can think about?……Also, from now on, don't call him Mars-san, but call him 'Master' or some other respectful name. Your position has changed from being a mere perverted woman to being 'Master's perverted woman'."

"Mars-san perverted woman ...... is something that really excites me. ......!"

"So ......――Oh, by the way, what was the condition Master was trying to tell her? Will you still have sex only with me?"

Lilia reminded him, and he balked.

The new slave in front of her was a threat.

Mars is gentle, but he has a weakness for lust. When Lilia asks him out, he is quick to take her up on it.

"Eh, yeah……That's what I was talking about.――I'll have Xerius declare it. 'It's not yours anymore'. It's a psychological break. It'll make you feel better, right?"

"It's neat ......, but it also sounds like it would be nice to feel good with another guy while thinking you're cheating on the one you're dating ......you know?"

――You've got a taste for cuckoldry on your side, Hazuki-chan!

You're a virgin and you want to be cuckolded?!

"So you're not going to have sex with me now? ......I-I'm already getting a weird feeling in my pussy thinking that I'm going to get Mars-sama cock. ......"

"You're weird……Are you always in heat? I've hardly ever seen you not in state like that, Hazuki-chan. And Lilia, she said that, but you can call me whatever you want, okay?"

"It's not like I'm always in heat. ...... I-I'm just kind of squeezing. ...... And I'm really slimy... ...I think it's blistering."

"It's probably because you are in heat. It is your body's desire for your master's child.――Well, I'm not denying that. It's not unreasonable."

Fuun, And although she sounded unhappy, the content of Lilia's speech made Mars feel embarrassed.

"It-It's a scam. ...... If I became a slave, would you have sex with me? I thought you'd do it for me. ...... But at this pace, We might catch up ...... soon. We are less handicapped than Xerius, and because we have these places to rest, we can go with a lot of energy. ...... The lack of physical loss is overwhelming."

Mumbling, Hazuki enters her own world.

A moment later, she changes her appearance to one where she can't see anything around her.

She puts her hand over her mouth and looks at the floor with vacant eyes, as if she is not looking anywhere.

"As far as I can tell, Xerius's stride length, the speed and strength of his companions, his planned rest time and fatigue level, the structure of the dungeon, the traps, the distance and time we've walked, and ...... the situation so far. To put it in perspective, if there are no obstacles, we might have a good chance of catching up in half a day."

"Eh?"

"Pervert Woman?"

Hazuki changed abruptly and started talking about the elements she had seen and heard so far.

After that, she pretended to write something on the floor with her fingers.

"The number of steps We walked today was around 150,000 steps. ...... we walked carefully to avoid traps, At 30 centimeters per step, that's just over 50 kilograms. There were thirty demon corpses that we had just checked. Assuming that it takes five minutes to kill one, Xerius had two and a half hours to stop. If he had encountered them at the same pace after that……――After all, we'll catch up in another half day. Even if I'm off by a little, it won't be more than a day before we meet up."

"――What? Isn't she an idiot, Hazuki-chan is?"

"E-even though she's pervert woman……!"

A straight-faced Hazuki looked at them and wondered.

"Uh, ......? Did I say something funny ......?"

"You was mumbling something about numbers."

"Ahhー……I've always been good at arithmetic and can calculate to a certain extent if I have the information. ...... That's about it. The numbers just popped into my head. ...... Should I have mentioned the detailed numbers? I'm not very good at explaining things.……"

With a slightly sly smile, Hazuki looked embarrassed.

――She's a science girl. ...... Or are you embarrassed there? 

There's more to ...... this than that!

"In conclusion, if I can just hold out for one more day or so, he'll have sex with me! I guess I'll have to say goodbye to Xerius!"

"――Are you okay with leaving him, Hazuki-chan?

Hazuki felt too merciless to Xerius.

Hazuki looks confused for a moment, but immediately makes a bitter face.

"I have some feelings about it, but I don't like it because ...... I get beaten up and I don't like it. ...... When he get angry, he put his hands on me. I had to put up with it in order to achieve my goal."

"I guess that doesn't matter anymore. ......"

"Yes, yes. I don't want him to die, but I already prefer ...... Mars-san as a lover. Oh, Mars-sama is better!"

It is good to be tied down when there is no choice, but it is a different story when other options are given.

It's not that he's unsympathetic or anything, it's just that Hazuki was thinking rationally.

There was no malice in it at all.

――Well, I guess that's the kind of girl she is.

Mars patted Hazuki's head as she sat and wriggled her thighs.
