Chapter 5: Crystabel is really horny

The nature of the mission shocked me to the core. I could not even lie at this point in time.

"Why is the mission this specific," I whispered a little.

It was not as if I was complaining. In fact I was very very happy. I mean who would not get a huge boner just by hearing the content of the mission. But it was still something that I was really very curious to know about.

And to my surprise the system actually responded, something I did not actually think was possible. Or rather I had never actually experimented on it.

[Well the system is a perverted one and would always grant perverted mission nothing more.]

Now that answer was cold and I loved it.

Without wasting any more time I stood up and walked down the hallway towards my elder sister’s room.

Mom had put her on the very last end of the corridor due to the fact that she was actually in medical school and would need maximum focus.

And to be very honest my sister was really gifted, but medical school still had a way of making someone work too hard. Either ways I really did not care about that now. The main thing was to complete the new mission.

As I approached her room I finally began to hear her inner thoughts again, giving me the sense that the inner thoughts had to do with proximity.

’My god I can only imagine moaning in that position, step sister is actually really lucky but I dont care this is all I have now and am gonna use it. Its not nearly as good as what Lille would have experienced but at this point I dont have an option.’

From my system interface I could see that Lille was still actually really really jealous. But I still did not understand what she was fully trying to do. So instead of knocking I immediately changed my mind and gradually moved to the window to take a look.

And I could not lie, I was shocked by what I was seeing. Was this not my serious sister, the medical prodigy that was always advising me to take my studies seriously? My god you have to be kidding me. This Saturday was boiling down to be one of the best Saturdays I have ever encountered in my perverted life.

From the window my sister was sitting in front of a desktop, maybe probably wanting to study or open up a site, but that was not my main problem. Her shirt was open, her large boobs sticking out and glowing severely from all the heat.

And it would not take much of a pervert to notice that her nipples looked as hard as a rock. The chair and table she was sitting on were facing the window.

But there was theoretically no way she could actually see me since there was a curtain over her window and I was just peeping through a tiny gap.

’Yh Lille keeps stealing everything from me but today she went too far getting pleasured by big brother. Big bro just see how hard I can cum for you if you let me to.’

With that Crystabel gradually rolled her gaming chair back away from the table. Her skirt was already raised up to a very far extent and I could see her pure white panties. And I kid you not when I say this. They were much more soaked than that of Lille. She must really be quite horny and jealous.

But that still was not the most shocking aspect. In front of my eyes Crystabel brought out Lille’s panties. Yes, this same panties soaked with our cum.

’This is his cum am sure his very semen am already aroused just smelling it.’

And just like that she brought it to her very nose and took a very deep breath, sniffing everything in.

’Yes that smell its too good I cant even lie its making me cum so hard. Dont worry big bro I would show you just how much I can cum for you maybe then you wont leave me for Lille.’

Well the truth was that all my sisters were actually older than me. Them calling me big brother was actually a nickname I got since after getting adopted. But that is a story for another day. Totally the main thing I wanted to do was enjoy the show for a while.

Crystabel made sure to rub the soaked panties on her hand for some while, prioritizing her fingers before finally taking it into her pussy hole and began massaging it along her swollen vulva. Also I could not see her vulva fully since her hands were actually inside her panties. But from how well her pussy was leaking I could guess that her pussy was going to be really nice to fuck.

’Yes brother yes am cumming for you yes fuck me more yes yes.’

My god I have not seen such a perverted scene in a long while. As though hearing my own inner thoughts she immediately began to squirt like crazy. Yes I really do get it. You can outperform your sister Lille now, could you stop making my cock throb so hard.

With every passing thought Crystabel kept getting more and more agitated. Without any warning she immediately ripped her panties off and pushed Lille’s panties into her nostrils some more. Her fingers began moving in and out of her pussy in a rapid and violent way. I was not sure if it was the jealousy or if she was naturally just violent when masturbating.

’Yes big bro yes fuck me harder.’

From her inner thought it was obvious she was imagining her fingers as my cock. My god it was as if she had gone into overdrive as she was just cum squirting so much, even taking the panties up to her lips and rubbing it all over them.

’Yes big bro I cant wait to actually give you a blow job.’

At that thought she finally let out her final loads of cum as she relaxed in her chair, clearly exhausted. But her hands were still going in and out of her tight wet pussy.

’Big bro I really cant wait to have you fuck this leaking pussy I really cant keep masturbating without ever experiencing that nine inch cock.’

With that I finally summoned the courage to finally knock on her door.
