Chapter 1: My perverted step brother

’Step-brother, could you suck pussy a little? I’m already wet just staring at you. Come on, your cock is already hard under your pants; I would love to at least feel it.’

Yep, I’m sure you couldn’t have guessed, though I’ll tell you either way, that those were my little step-sister’s perverted inner thoughts. In fact, all three of my step-sisters are perverts.

For the past week, my life had ceased to be mundane after I awakened the Perverted Stepson System. Now, I can hear all my step-sisters’ perverted thoughts, and trust me, it’s been a lot of fun.

Not that I’m complaining, as I’m probably the biggest pervert in history. I’m always glancing at their smooth, succulent inner thighs when they’re seated, sneaking into their rooms to grab their underwear when they’re not around, and acting way too intimate with my innocent, unsuspecting mom. Even at school, I always "accidentally" drop my pen just to take a glance at my classmates’ underwear. Yeah, the classic pen drop.

Of course, my beautiful step-sisters noticed my perverted actions and always treated me like I was disgusting. Despite treating me nicely in public and making me somewhat popular as the guy with three cute, busty sisters who would kill for him, it didn’t matter much if they still thought I was filthy at home.

Only that changed after I awakened the

Perverted Stepson System.

Now that I could hear their inner thoughts, I couldn’t be more surprised. Each time I sniffed their panties and got caught, it sent a wave of dopamine rushing through their blood vessels. Staring at their plump asses and succulent inner thighs made them wet on the spot.

They were just as much of perverts as I was, but far too proud to admit it. No wonder they were always so protective of me in public and had never revealed my perverted nature to our mom.

I stared at my step-sister, Lilly, who had half of her body out of the entrance to her room. Her actual words were:

"Hello, Steven, please could you help me with my homework? I am having trouble with it, and I think now that we are alone would be the best time to tackle it. Also, please don’t behave weird."

But that was just surface talk, and we already knew what her perverted inner thoughts were actually saying.

Gradually, my eyes drifted down to her huge breasts, which were sticking out of her top, and of course, I noticed her cheeks redden immediately. Today might as well be the best day to finally accomplish the system’s damn starter mission:

[Grant the perverted thoughts of one of your step-sisters. Reward: Full system features unlocked.]

Right now, I could only hear their perverted thoughts until I finally managed to fulfill that mission. But today is Saturday, exactly one week since I got the system, and it’s the perfect day to get it done.

My mom is off working, after which she’s going clubbing, meaning she won’t be back until midnight. My eldest sister is off studying, after all she’s in medical school, and won’t be back until late either. The second-born is also going to be out late drinking. That leaves me with the youngest.

And boy, do I have a lot of time on my hands today to finally get this done.

"Why are you staring at me like that? Aren’t you going to help me?" Lilly said with a slight frown.

’You didn’t need to raise your head; I need your eyes on my shameless boobs.your gaze is getting me wet and I love it’

" let’s do it immediately. I would also want to go out afterwards," I replied my throat already going dry at the filthyness of her inna thoughts

"Sure, let me dress into something more comfortable, and then we could begin," Lilly said with a bright smile before rushing back into her room.

After waiting a while, she came out dressed like a real stripper. Although she claimed it was casual and comfortable, it was still far too hot for me to handle. Because what the hell, she was wearing a miniskirt and a crop top which was already sagging due to the sheer weight of her boobs.

that wasn’t even the worst part. The whole outfit was see-through. Yes, I mean totally see-through. Man, if you want me to fuck you, just fucking say it.

I gave her a very thorough, predatory gaze, stripping her clothes right off her body with my eyes as I took in every single part of her beautiful figure.

"What’s the problem? Won’t you come in?" Lilly said with a slight frown, though her expression already gave her away.

’I wish I could ask him if I’m sexy enough.

and Yeah, that gaze already gets me wet. What a gift of a brother, I love you more than you can imagine.’

My cock immediately began throbbing I could even recognize my sister again. Her thoughts where far too filthy

But Lilly is quite cute, I must admit; even her frowns are adorable. She was sweating all over, after I stared at her exposed figure, and she didn’t even complain or try to hide it. It was like she was inviting me in for more.

My goodness, this Saturday was really going to be nice.

"So, are we going in or what?" Lilly said, tilting her head slightly and gesturing toward her reading table inside her room.

Deep down, I knew she wanted me in there for something totally unrelated to studying, but oh well. I was here to grant her perverted wishes, so I can’t complain.

I immediately moved into the room and took a seat at one of the two chairs at the reading table. She followed right behind me and made sure to lock the door.

There was nobody else home, so she probably just wanted an extra layer of privacy, or protection.

Without sparing me a glance, she sat next to me, and instantly I saw it: her thighs and inner lap were totally exposed.

I could even get a faint glimpse of her panties right from beside her.

So, of course, I let my pen fall into just the right position to get a really good look.

Authors note: I would try my best to put the inner thoughts of people aside from the mc in italic but if it is just single quotes then that’s the stevens inner thoughts
