I'm currently in a dim room with both my hands and feet tied up.

"Mmuh–!?"

What kind of situation is this!? I try to cry out for help, but a gag has been forced into my mouth.

"…..Fu~fu~, Yuzuki onii-san finally woke up."

I could hear an innocent voice coming from somewhere above me.

I twisted my neck to look around and I was able to see Rose's face looking down at me. Her position was confusing me until I realized she had my head sitting on her lap.

"What's going on!? What are you planning to do!?"

"Fufu, I don't know what you're saying."

Rose smiled and removed the gag.

"What are you planning on doin— mugu!?"

Once I was able to talk, my mouth was immediately covered again.

— However, this time it wasn't a gag, Rose's small lips were covering my mouth……is this a kiss!? Why is she kissing me!? What is going on!?

"…….~n chu~……ha~a"

A few minutes pa.s.sed while she continued to do this before she finally moved back. There was a transparent thread of saliva that connected Rose's mouth to mine.

I had been holding my breath almost the entire time and was only now able to breathe comfortably.

"…haa…..haa…..Rose, what are you…."

"Fufu, that was my first kiss. Make sure you remember it."

"……I won't forget. I'm sure I'll remember this situation for the rest of my life."

Why do I feel so unfortunate to take a girl's first kiss? More importantly what is with this situation!? I'm tied up in a dimly-lit room and a young blonde girl just forced a kiss onto me.

Even if I wanted to forget this I wouldn't be able to.

"……So, why am I tied up? If you're willing to explain, I'd like to hear the reason."

When I tried yelling, she forced her lips onto mine.This time, I'll try asking in a calm voice. To my question, Rose answered with a truly innocent smile.

"Yuzuki onii-san is bad. I asked you to stay with me here and you refused…….So, obviously, I had no choice."

"Wait, you're saying you've tied me up here because you didn't get what you wanted?"

After hearing Rose's words, I got a little angry.

Because she didn't get what she wanted, she forced me to do what she wanted. She's just like every other Yandere I've met.

I thought Rose was a kind girl that cared for others, but….it was just my misunderstanding. Therefore, I'm angry with myself for believing in Rose even for a moment.

I'm becoming visibly irate at this point and Rose is just continuing to look down at me.

"…..What is it?"

"Yuzuki onii-san, you don't need to be scared."

"……I think most people would be frightened in this situation."

Well, it's not like I haven't been in a situation like this before. In the worst case, I'll be killed, but then I'll just revive anyway.

On top of that, my willpower rank is AAA and my fear resistance is B so I'm not feeling too scared. To be honest, I'm not really scared at all.

But, I have no reason to tell that to Rose.

"You say that, but you're not trembling at all. After all, Yuzuki onii-san truly is amazing. From the first moment I saw you, I felt like we were destined to be together."

"Destined to be together……are you sure it's just not a misunderstanding?"

It's a terrible thing to say, but I don't have much choice here.

Because of my rare skill being rank SSS, I'm sure it's having a strong effect on this young girl.

Well, it is nice that she seems to love me, but……If she just likes me because of the skill, it would be less nice. Rather, if she likes me because of the skill, I'd feel bad for influencing her in this way.

"We're finally alone now, but you don't seem to be happy."

"Well, my hands and feet are tied up so there's not a lot of reasons for me to be happy."

"That's because Yuzuki onii-san is too strong. I'm trying to convince you to stay with me, but if I let you go free you'll just run away."

"If I tell you that I won't run away, will you free me?"

"……Do you promise?"

Rose looked deep into my eyes with her multicoloured eyes. It seems that she's trying to decide if I'm telling the truth or not.

But that also means, If I can make her believe me, she will untie me.

I looked straight into her eyes and nodded.

"…..Then, if I untie you, will you listen to what I have to say? You promise that you won't leave this room?"

"Yes, I promise you."

Of course, I'm lying. Still, lying to such a young girl feels wrong.

But I really don't want to spend the rest of my life trapped in a room by a Yandere girl. Shortly after, Rose smiled and said, "It's a promise,” and she untied my arms and feet.

……Too easy.

But, I still need to be cautious. It would be stupid to try to run away now.

I sit up first and make no move to leave the room. I say, "Thank you," to Rose and gently pat her head.

Rose narrowed her eyes and seemed to enjoy the feeling.

"Hey……Yuzuki onii-san, that feels good, but you know you can touch me in other places too…"

"……other places?"

"Yeah, other places. Yuzuki onii-san is mine, but I am also yours. So, if there's anything you want to do to me, I'll let you."

"A-Anything?"

"Well, if there's any clothing you'd like me to wear, even bold clothing, I'll wear them. If there's anything you want me to do to you…….I'll do it."

"T-That's….."

I instinctively swallowed my saliva.

No, it's not like that. This kind of reaction is only natural for a man. Rose is an incredibly beautiful girl. To say I can do anything — of course I'd be interested……I need to calm down.

If I succ.u.mb to temptation here, I'll lose my chance to escape from this room.

"Yuzuki onii-san?"

"Umm, well……It's a very attractive proposal, but I'm really thirsty. Could I get some water?"

"….You're thirsty?"

"Yeah, it's painful."

I'm trying to create a chance for me to escape, but I really am thirsty. I'm currently in a dark room on a bed with a beautiful girl and all I can think about is my dry throat.

"Okay, then, I'll get you some water. In the meantime, Yuzuki onii-san should think of what you'd like to do to me…"

"Y-Yeah, I'll think about it."

After I nodded, Rose left the room to get some water. I let out a sigh of relief when I confirm she's completely gone.

….Alright, I should be fine now.

Then, I need to think about what to do before Rose gets back — not what to do to her, but how to escape. I need to get away and this will be my only chance to do so…..

…..Well, it would be nice to see the innocent Rose dressed in provocative clothing and I could enjoy her embarra.s.sed expressions. I could even teach the innocent Rose about various…….

No! This isn't the time to be thinking about that!

Though I'm definitely in a pretty bad situation, I still feel pretty calm.

That's definitely due to my fear resistance, but I'm actually being tempted by her. It might be better for me to increase my seduction resistance.

……This isn't the best time for me to be thinking about this.

I made up my mind and looked toward the door that Rose went through. I made sure that I couldn't hear any noise from outside the door and I slowly…quietly….opened the door —- Why won't it open!?

U-Uh….That's strange. I don't remember Rose unlocking the door when she left, nor did I hear her lock it when she left. It shouldn't be locked.

No, it's definitely not locked by a key. I can't seem to turn the doork.n.o.b with my hand.

Could it be that I subconsciously just want to stay here and do stuff to Rose? That's ridiculous…….There's no way that's true.

There has to be some kind of magic that was applied to the door.

I don't know the exact details, but it seems impossible for me to escape using this door. Let's try the window.

It might be locked……It opened!

I could escape from here, but the ground is probably two meters or so below the window. There is a chance I could seriously hurt my feet dropping from this height, but in the worst case scenario, I always have 'Immortality.'

The door is impossible to open so I have no choice. I put one foot on the window frame and pulled myself up — as I stood there, a sudden fear gripped my heart.

"Guh—–ha, wh-what is this? What…..What's going on — kuh!"

I can't stop trembling, even my breathing is getting ragged. My fear resistance and willpower don't even seem to be making a difference.

—Why am I trembling?

The door slowly opened and Rose entered carrying a tray with a cup of water.

"I'm back~…….Eh? Yuzuki onii-san, what are you doing there?"

I didn't even think about the fact that I had lost my chance to escape. On the contrary, I felt relieved to see Rose and ran to hug her as she entered the room.

"Rose, Rose!"

"Hyan! Onii-san, what are you doing? The water spilt."

Rose dropped the tray and the water spilt all over the carpet. But, I can still feel the fear that was crus.h.i.+ng my heart. I desperately clung to her small and soft body.

I could feel the crus.h.i.+ng fear slowly leaving my body.

However — Just as I was starting to feel relieved, I could hear Rose whisper, "Did you try to escape?" I jumped back out of surprise after hearing her words.

"Aha~, so you really did. Mou~, that's not good. You promised not to escape this room. Didn't you listen to me properly, you made a contract with me."

"……A contract?"

"Yes, a contract using my demon eye."

Rose used her right hand to open her golden eye. It would usually be cute, but I can't get over that terrible fear I was feeling earlier.

"That golden eye….is it a demon's eye?"

"Yep, we formed a contract using my demon eye. It’s a contract that will never end until one of us dies. Still, I was worried because Yuzuki onii-san is so strong I thought it may not be able to affect you, but I’m relieved to see it worked."

I made sure to look into her eye and promise as well — it’s frustrating.

I should have known better. This world has magic just like a game and Rose has a demon eye. I thought there may be some kind of power like that in this world, but…..No, I need to stop thinking about my mistakes and try to find a way out of here.

The promises with Rose were 'I won’t leave this room' and 'I will listen to what she says.' I need to find a way to leave this room without breaking those promises.

…….That’s impossible.

However, if I give up now, I’ll be kept here until I die…. Well, even if I die I’ll just be resurrected.

If I do something wrong, that may happen…..Wait a minute.

Rose said earlier if either of us dies that contract will end. By that logic, if I die and revive, the contract should still be invalid…..right?

……First of all, I open my status window to confirm something.

I was worried that Rose may be able to see it, but…..Apparently, my status window isn’t visible to her. She shows no reaction whatsoever when I opened it.

However—

"Yuzuki onii-san, I don’t know what you’re thinking about, but…..Don’t you think it’s about time we start?"

I fall completely silent after hearing her words. Rose pressed her body against me and looked up into my face. The way she’s looking at my doesn’t match her young appearance.

"….W-Well, what could you be talking about?"

"It’s what we were talking about earlier. Please, touch my body."

Rose makes this request in the form of a command. At that time, my arm moved around behind Rose and my hand started rubbing her back.

"Hya~…… ~n ha~a……. That tickles."

Rose twists her body around, but my hand keeps rubbing her back as she says this. Seeing her react like this makes me think of other things we could do. I can feel the blood rus.h.i.+ng to my head.

"Fufu~, you can touch me in other places too. I’ll also touch you wherever you want."

"No, that’s—"

T-T-T-This is bad. This is very bad. If I just let Rose do what she wants, this will escalate quickly. I won’t be able to calmly think about a way to get out of here.

"Please wait! Umm….Well…Let me go first!"

I think I just said something I can’t come back from.

"Yuzuki onii-san wants to go first? What do you want to do to me?"

"Umm…..Well….That’s right. Since I’m lying on the bed can rose sit facing me on the bed?"

"Eh? You want me to be on top? Well, I would’ve liked to go through a few more steps before getting to that, but…..If that’s what Yuzuki onii-san wants……"

"Y-Y-Y-You're wrong! I just want to touch your body! So, please don’t take off your skirt!"

I desperately tried to stop Rose before she finished taking her skirt off. She then gently opened her legs before sitting on my lap.

If someone were to walk in on us, it would definitely look like we were in that position, but — nothing has entered.

Anyway, Rose sat on me leaning back onto my knees while I gently stroked her stomach.

“Hi~yau~….. Ah… Ah~…… Uku…Hya~n. Yu-Yuzuki onii-san, something feels s-strange. Ah~n, it’s ticklish~"

I can feel Rose’s body start to tremble.

She’s saying it’s ticklish but she’s letting out pleasurable moans.

Maybe she’s confused because she’s never felt like this before. I’m also confused because Rose is grinding her body against me. I didn’t think rubbing someone’s stomach would be so s.e.xual. I was also getting excited. Before I even realized it, I had started moving my hands up Rose’s dress and started rubbing her chest.

There is underwear in this world, but Rose wasn’t wearing anything like a bra.

Underneath her dress, I could feel her naked breast with my hand.

The size of her soft b.r.e.a.s.t.s didn’t match her young appearance. However — as I stroked her chest I could feel her nipples get hard and rub against my palm.

Rose continued rubbing against me as I stroked her chest. I could tell she was feeling even better than before so I started rubbing her chest with my entire hand.

"Ah~….. ~n. Hii~ I can feel something th-throbbing."

"…..Rose, your nipples are hard."

"Eh? Eh? What do you mean? I don’t understand, but it feels great when you touch me. Fwa~…..something feels amazing…..nha~!"

I leaned forward and pressed my lips to Rose’s ear.

"Rose, how do you feel?"

"Ahn~, how do I feel? I…. I feel… hyan~ Yuzuki onii-san's hand makes me feel…..fwaaa~!"

“Right. So, why won’t you say it feels good?"

"Y-Yes! Uku~ Yuzuki onii-san's hand feels so good~ I feel so good~ Yuzuki onii-san's touch feels so good!"

Rose let out another sweet moan. I confirmed she was getting close and stopped moving my hand.

"…..Where do you feel good?"

I asked Rose this after I stopped moving my hand.

"……Eh?"

"When I touch you, what part of you starts to feel good?"

"That’s……it’s too embarra.s.sing…..I can’t say it."

Even if she really doesn’t understand s.e.x yet, she knows that talking about that part of her is embarra.s.sing. Seeing her embarra.s.sed like this is nice. Ah, I want to see more of Rose’s embarra.s.sed expressions.

"……. If you don’t tell me, I don’t know where to touch…..umm…..like, what about here?"

I play dumb and began gently caressing her arm. It creates a completely different feeling than before.

"Hauu~….that’s not the place. Hya! That…place….. Ah~ That’s not the right place. O-Onii-san is so mean."

As I continued stroking her arm, I also slid my hand back up her dress and placed my hand on her chest.

Rose let out another moan that was similar to the one Medea-nee let out.

"….Uu, touch, touch my chest. Please, touch my chest more!"

"You want me to touch your chest?"

I lightly placed my hand on one of her b.r.e.a.s.t.s, but I made sure not to touch her nipple.

"Yuzuki onii-san is too cruel! I want you to touch my nipples like you were before! I’m asking that — because it felt so good! It felt good! It felt so great! Aaahhhh~!"

After hearing Rose’s words, I started rubbing her chest while playing with her nipples.

"You’re so cute, Rose. I’ll make you feel even better."

If things keep going like this I may be able to get a chance to escape — I started using my other hand to rub Rose’s stomach and neck.

As expected of a daughter of a n.o.ble — her entire body is so smooth and soft. On top of that, the feeling of her entire body trembling against me is great.

If only she weren’t a Yandere……

Honestly, it’s terrible that she is. I changed my focus to my status window as I continued moving my hand unconsciously.

There have been some changes in my status window. I now have a new status called 'Contract with Rose: E.' The rank of that status is increasing, but my SP has also increased to 105.

According to the log window, I received 100 SP for saving the Countess' daughter and 5 SP for defeating the thief leader…..That seems like a small amount for someone that was supposedly strong.

In addition to that….there appears to be a log saying I took sleeping pills. It seems that I fell asleep during dinner because she mixed sleeping pills in with my meal.

In any case……When I think about being drugged and tied up, I feel a little scared, but I need to focus.

I open up the details of the contract with Rose. The details were almost exactly the same as what Rose had told me earlier.

However, it seems possible to dispel this magic if you are able to use a dispel magic of a higher rank than the contract. The only other way of ending the contract is by either Rose or myself dying.

I can rank up dispel magic with 200 SP. The contract is rank E so I’d need to level it up to D to be able to end it. To do that I’d need 1200 SP……of course I don’t have enough.

"—Hyan~ kyu~ it feels so good. I feel so good. Yuzuki onii-san. Ah~ ah~ More, make me feel even better."

Rose’s voice is getting even more erotic, but I just try to block it out and focus.

I’m currently looking at the skill [To Be Loved to Death by Yanderes] the skill I don’t know how I got or how it ranked up so high.

First of all — I need to look at the details of that skill.

[To Be Loved to Death by Yanderes]

A Yandere's obsession with you is increased.

F: No increase E: 5% increase D: 10% C: 15% B: 20% A: 25% AA: 35% AAA: 45% S: 60% SS: 75 % SSS: 100%

【E rank bonus: You will catch the eye of any pa.s.sing Yanderes. + 10%】 【Rank A Bonus: Increase the Yandere attribute of anyone nearby that likes you. + 10%】 【S rank bonus: Draw out the potential Yandere attributes of any surrounding people. +10%】 【SSS Rank Bonus: Draw out and amplify the Yandere attribute of any surrounding people. + 10%】

….Oh, what an annoying skill. Maybe this skill is why Rose suddenly became a Yandere.

No, the increase in the Yandere attribute isn’t that great.

Even if I a.s.sume she liked me, the increase would only be 20%. Even if that did affect her, it’s likely she was already a Yandere before we met.

"Yu-Yuzuki onii-san, something, something's coming! Fwaa~! This is….amazing. Ah,~ ahn~…..Hyuu~n!"

Rose is gradually raising her body. I noticed this and placed my hand under her skirt on the base of her thigh.

Her underwear is completely soaked.

"Hyaaan~! So-Somehow, when you touch there, my mind goes completely white. Yuzuki onii-san, touch….touch me more there."

When I pressed my fingers against her soaked underwear, the love juices inside flowed out.

While I rubbed my fingers over her underwear I continued rubbing her chest with my other hand.

Rose tensed up even more and pressed her body even harder against me, but I can't lose focus now.

While still attacking Rose, I returned my attention to my status window.

I was now looking at one of my new t.i.tles.

[Received G.o.ddess Medea's Love] This ability is supposed to increase all of my skills by 10%. It also has the ability to affect someone that is close to me.

The second part of that worries me, but that t.i.tle doesn't seem to be of any help right now. I turned my attention to the next t.i.tles.

[A Traveller From a Different World] and [Loved to Death By Yanderes] they increase all of my skills by 5% and 2% respectively.

Also, the t.i.tle [G.o.ddess Medea's First Love] increases my skills by 10%. All together, all of my skills are increased by 27%.

On top of that, my physical strength was already increased by 10% so in total it is now being increased by 37%. This is why I was able to defeat the leader of that group of thieves so easily.

"Yuzuki onii-san, Yuzuki onii-san! I…I feel strange! I feel like my mind is going crazy!"

"Don't worry. You're about to feel amazing."

"Amazing? This is, fua~a…..Yuzuki onii-san, are you going to make me feel good with your fingers?"

"Yeah, that's right. With my fingers…..I'll make you feel great."

"Y-Yeah, make me feel even better. I….hya! Ah~ ahn! I..I'm……Yuzuki onii-san's fingers feel so good~~~~~~!"

Rose's body tensed up and then collapsed into my arms. I could feel her body trembling against me……This scene is incredibly lewd.

"……Are you okay?"

"Hyuu~….Wafu~…..Onii-san, I….I don't know what that was…..My mind went completely white and my head’s still spinning. I'm not fine at all….."

“Fumu, then…….do you not want me to touch you more?"

"T-That's…..well…..If Yuzuki onii-san wants to touch me more……well…..you can."

Rose's cheeks were dyed red and she was avoiding my eyes as she said this. That's a nice sight — That slightly greedy expression is the cutest.

I was thinking she was like this due to the [To Be Loved to Death by Yanderes] skill, but, even though that skill is rank SSS, that skill would only double her affection for me.

That doubling effect is amazing, but it wouldn't apply unless she already liked me in some way.

Having said that, Rose seems to like me more than just a little…….honestly, that does make me feel good. And I'm not talking about Rose pressing her body against me.

As I was thinking about this, I could feel Rose start to fidget on top of me.

"Ah, umm Yuzuki onii-san, can I……..Umm, is it okay if I go change my clothes?"

"Change your clothes?……Ah, yeah go ahead."

Rose quietly got up and left the room. I got up from the bed and went to the door to confirm she was gone.

She's currently changing clothes, though she may not be changing her entire outfit, so I'm not sure how much time I'll have.

So — I quickly opened the skill tree on my status window. I'm trying to find any type of magic that I could use here. The skill I was currently looking at was 'Fire Bolt' and I can learn it for 100 SP.

How to use this ability: imagine the object and declare the name of the spell. Then, a magic formation will form on the ground and the Fire Bolt will be created when that is done.

Although just by learning it I'll be able to use it, there will be many disadvantages. At rank F I won't be able to use it when I'm moving, but that shouldn't be a concern here.

I got the rank F Firebolt at once.
