I wanted this so badly

I think about 3 to 6 months have passed since the time travel, I don't have much sense of time in this room.

During this time, I've only talked to Leviathan and Valac and deepened my feelings for both of them even without sex.

Valac and Leviathan were clearly wanting to, but I somehow managed to avoid sex. With Leviathan, I just offered a lot of blood at once since Leviathan likes to eat more than to have sex.

However, with Valac it was difficult, everything for him refers to sex, and I tried many ways to avoid sex, it's not that I don't want to, it's just that I'm driving them crazy for that.

So that when they finally can't take it anymore and decide to take it by force, the pleasure of sex will be better, so I'm basically waiting for their lust to explode so they can catch me.

During this time, I was obviously staring at the wall non-stop, waiting for Beelzebub to get bored with it, I also asked Valac for books.

The reason for this was because I knew Valac would only give me erotic books and that way I could learn sexual techniques without problems and I can have an explanation for why I'm good at sex even though I'm a "virgin".

And so we end up in the current situation, I'm looking at the wall while waiting, next to me there are plenty of erotic books that I've already finished, there must be at least 90.

This fills me with lust and makes me want to masturbate, but since I came back in time, I've never masturbated, even though I really want to touch myself, it happens that I can't give this entertainment to Beelzebub.

'I wonder if Uriel is okay...I want to get Aetheris back soon...' The world seems worse, the opacity of the world has worsened, becoming quite gray, and now I can barely feel anything when I look at things in general.

What makes me feel the need to stay close to Valac and Leviathan, who are colorful.

It happens that my plan to bore Beelzebub backfired and only made my problem worse and made me more depressed, I know it's my fault, if I let my regeneration take care of it, I wouldn't have this problem.

But my memories don't let me, just as I have traumas because they are memories, I've developed a kind of depression because of myself as self-punishment and I can't get rid of it because I hate myself, I see myself as a monster, I see myself as dirty and useless.

And as long as I continue to see myself negatively, this will probably not change, I wonder if in a few years I'll stop feeling everything and will only be able to feel things when the beings are colorful.

"..." I get up for a moment and go to the table, taking the books to free up space on my bed.

'...I'm colorful...' My arms stand out more in the gray world, and when I look in the mirror, I can see that I'm colorful, I'm not sure why I'm colorful or what the criteria are for things to have their normal color for me.

"Hello, little sister!!" Valac opens the door excitedly as he enters my room and sees me taking the books to the table.

"Hello, big brother, how are you?" I say with a smile, I like his colors, he is so bright and stands out so much in the gray world, and that's why he immediately catches my attention.

"I see you were reading the books I gave you, what did you think?" He asks as he approaches.

"Ah...I-It was nice" It wasn't bad, though it was just an excuse, it helped to relieve the boredom, Valac gave me these books a few days ago and I finished them about an hour ago.

So I'm very excited, very excited, I can barely control myself because of how horny I am since I can't satisfy myself alone.

"Little sister, you smell so good, it seems tempting" He approaches completely, his shadow covering my body a bit due to the lighting.

"Ah...I...thank you, big brother" I take a step back.

'He can't hold back anymore?' I wonder if he'll act now, I'm even fantasizing about him suddenly throwing me on the bed and raping me, I'm really very lustful at the moment.

"Little sister, how about we try something from the books today?" He speaks sweetly and gently, but the lust in his eyes is obvious, he's asked me this kind of thing several times in the last few months.

"I-I'm sorry, big brother, I'm not ready for that" I deny, seeing how far we'll go, will he accept this?

"Little sister...Tsk" He clicks his tongue and seems annoyed.

"...Little sister, are you sure you don't want to do anything? I see you also seem excited?" He speaks while taking a deep breath.

"Yes, I'm sure, big brother, let's just talk?" He seems annoyed, after all, all we've had are conversations and at most kisses that occurred when he manipulated my mind with magic.

"...Alright, little sister...let's talk, I'll offer you a cup of tea to accompany the conversation" He speaks as a teapot appears, he sits at the table and serves a cup for me and one for him.

He always does this, I think it helps him calm down and also must help to gain my trust in case he wants to drug me at some point.

"Of course, big brother" I say as I sit in the chair and take the cup from the table, Valac also sits down and takes a cup of tea and starts drinking while staring at my breasts.

"Little sister, have another, what do you think of the flavor, is it to your liking?" He puts another cup for me while not stopping staring at me with lust.

'So he decided he can't hold back anymore...' I get a smile on my face.

"It's very good, big brother" I praise the tea he gave me while I wait, it's similar to the past, the tea must have an aphrodisiac and he'll start brainwashing me.

Although I'm already full of lust, so I don't think I'd need aphrodisiacs.

"..." I cross my legs as I feel a pleasant and tingling warmth.

"B-Big brother..."

"Yes, do you need something, little sister?"

"..." I feel very tempted to beg for sex and it seems to be increasing, I know that if I wait a little while, I won't be able to control myself anymore.

But since he's so tempted to rape me, there's no reason to deny it, I really need it as much as he does.

I get up and go to him, who is slightly confused, after all, I'm not 100% affected yet, so I shouldn't be going after him.

I get on his lap with a little smile.

"Big brother, I'm so hot, please could you help me, I-I didn't want to disappoint you" I say to him in a somewhat crying way while moving my hips, rubbing against his protruding cock.

'Ah...I want this inside me so much that it hurts...'

"Disappoint?" He questions.

"Y-Yes, I thought you wouldn't like a forward girl, sorry I couldn't control myself"

"So that's why you always denied?" I nod.

"Don't worry, little sister, I'd love to help you regardless of whether you're forward or not" He speaks while holding my hips.

"Really?" I think he'd prefer it this way, giving him a reason to have resisted so much.

"Yes, little sister, so how about you choose the content of one of the books for us to do?""

"Okay, I want this book here" I pick up one of the books from the table and hand it to him, I didn't look at which one I picked, so I left it to chance.

"Hmm, it's a very good choice, I didn't know you liked this kind of thing" He says as he shows me the book.

'...'

"Y-Yes, I like this..." It's not really my thing, but I guess it doesn't hurt to try, plus seeing the image makes my pussy drip with temptation.

"Then we can start, little sister" He starts tearing my clothes without caring much about them, while I take a deep breath, I'm too excited at the moment to really care about the clothes.

"..." He snaps his fingers and soon my hands are chained, and only one of my legs is chained and raised up, with the other leg touching the floor with difficulty since I'm almost suspended in the air.

It hurts a bit to be in this position, and soon I see my brother with some things to use on me.

"B-Big brother, you can start" I tell him, he goes to the table in my room, which now has some things, he picks up a very thick vibrator and dips it into a pink liquid jar.

The book had a BDSM theme along with humiliation, which is really ironic since this wasn't the book I left on the table, so Valac switched it because on the table there were books with a regular sex theme.

So he chose this because of what I said about disappointing him for being a forward girl.

"Hmmmm" I let out a moan as he pushes the vibrator deep into my ass, it hits so deep that I can't help but moan.

'This is so good...I want his cock in me soon!'

"Hahaha, you liked that? I thought you'd scream painfully or give a little squeak, it seems I have a masochistic little sister" He grabs a whip from the table.

"Y-Yes, I'm a masochistic little sister"

"Hyaaa" He whips my ass while the vibrator starts vibrating strongly, my love juice flows as I look at my belly, seeing the bulge moving.

"Shouldn't you say something, little sister?"

"S-Sorry for being a naughty little sister hyaa" He gives another whip that sends a shock of pleasure through my body, making me orgasm, the aphrodisiacs acting to increase my pleasure.

"That's right, now that you've apologized, shouldn't you beg for me?"

"B-Big brother, p-please use my needy pussy, I-I beg you"

'Can I use the stone to see the real system...'

"Big brother, c-could you prevent anyone from seeing this? It's just that I don't want to share the moment, o-only you, big brother, can enjoy this"

"Of course, little sister, you're right, I think I want to enjoy you all to myself without sharing with anyone"

"Hhmmmmm!" I let out a moan as the vibrator in my anus sends me a wave of pleasure that makes me orgasm, leaving me more sensitive.

"Little sister, I think I can't waste time acting, I've waited too long for this, after all, it's been a good time just talking"

"Huh?"

"Gyhhmmmm" Valac suddenly comes to me and shoves his cock into my pussy all at once.

"B-Big brother, go easy" I say, holding back the moans as he just ignores me and accelerates his movements.

'I-It worked...p-please don't stop, hit deeper and harder' I think, he really can't hold back his lust and just started fucking me, I hear the sound of the chains as my insides have a great pressure from having his big cock in my vagina and the vibrator in my ass.

"Big brother, I'm going to cum"

"Go ahead, little sister" He starts giving strong thrusts, pushing my uterus up while slowly invading it.

In a final hard thrust, he invades my uterus and starts cumming.

"Aahhhhhmmmm" I moan loudly with pleasure as I feel his mana infiltrating my body, and I orgasm hard, squirting love juice, and my mind goes blank.

'This is it, I wanted this so much, it's so good, so good, please don't stop!' My mind has become very perverted.

"What did you think, little sister?"

"S-So goooooddddd" I say without being able to control myself, drool dripping from my mouth, I've been waiting for this for months, I think I've become addicted to receiving their semen, I love the feeling of their mana invading me.
