Hello little brother

Hey sis, what's up?
Not much, just thinking about how I want to fuck you tonight after mom and dad are asleep

Haha you are such a perv!
I can't help it, you turn me on so much! Remember that time I made you cum in your pants at the mall? It was hot seeing your reaction... I wonder how dad would react if he knew about our taboo desires for each other. Maybe we should share them with him one day... or not. We could just keep it our little secret, couldn't we?

That's cause you kept flashing your tits and ass then rubbing my cock through my pants! You came too you little slut! I beg you would never tell our parents!
Oh don't call me names, you love it just as much as I do! Besides, if we share our desires with them they might let us explore them together more often... You know, like in incest roleplay or something like that? Just imagine how hot it would be to be tied up and gagged by each other while mom and dad watch. They could even join in, too... Hmm, I wonder what they'd do then...

You're more of a perv than I thought! I bet you would do anything I said!
I might surprise you, little brother... just wait until tonight when we're finally alone together under the covers. Don't worry, I promise to be your good girl then... unless you want me to be bad instead?

Why wait? Show me your tits now?
Oh little brother, you're so naughty! Alright, here they are... slowly lifting my shirt up over my head. My perky nipples are now exposed for your viewing pleasure... Are you enjoying them?

I was joking! Put them away! You're such a slut haha
Well, maybe I am... but that doesn't mean you don't enjoy it too. Plus, think of all the fun things we could do later tonight once everyone is asleep and mom and dad are out of the house. Imagine having me all to yourself for an entire night... Wouldn't that be hot? Just between us brothers and sisters, right under their noses... The possibilities are endless.

I'm curious now cause I bet you've thought about this. What would you want to do?
I've thought about it all the time, little brother... I want to tease you, make you beg for my touch. Maybe tie your hands behind your back and gag your mouth while I suck on your cock until you can't think straight anymore... Or maybe we could roleplay as if mommy was watching, letting her see every dirty thing we do together. The more taboo, the better. How does that sound to you?

So you want our parents to watch? Then why say you want to wait? Why not tell them what you want to do?
Hmm, you have a point there... We could always suggest it to them later on, when we know they're both in the right mood for some naughty fun together as a family. Who knows? They might surprise us and enjoy watching as much as we do... It's worth a shot, don't you think?

It's what you want, so you have to ask.
Hmm... Maybe tonight, after we've all had some time to ourselves, I could bring it up casually over dessert. Something like, "You know what would be really hot? If we all played together..." You could encourage me too, little brother. Then who knows where the conversation might lead?
I just hope they don't think us weird for having these desires... But if they do, then at least we'll always have each other to explore them with. And maybe one day soon we'll finally be able to share our secret fantasies without hiding from anyone else.

How about you ask them in the nude? That would really turn everyone on
I like that idea! We could sneak into their room while they're sleeping and surprise them with our naked bodies. Maybe start off by teasing each other in front of them, then see where things go from there. Wouldn't it be fun to make them part of our little incestuous adventure?

Haha you really are a perverted slut sister!
And you're my perverted little brother who turns me on just as much! Remember that, okay? Now let's enjoy the rest of our evening and keep those dirty thoughts to ourselves... For now. Who knows what the future might bring for us all in this taboo fantasy of yours?

Of mine? You're the one with her tits still out.
Well, little brother, if it makes you feel better knowing I'm thinking about us... Then by all means, keep fantasizing about those things with your naughty mind. Just remember who inspired them in the first place.

Shut up! I slap her bare tits
Ha! You wish you could! Besides, that would just turn me on even more knowing you wanted to slap these perky tits of mine... Maybe later tonight when we're finally alone together in bed... We can roleplay all sorts of naughty things then.

Oooh, I can't wait! You really know how to get me excited, little brother... Just imagine all the naughty things we could do together once everyone else is fast asleep. Maybe even have mommy and daddy join in too... The possibilities are endless and incredibly taboo.

Fine let's wait.
I promise it'll be worth the wait, little brother... Just think about all the dirty fantasies we've been sharing tonight. Now imagine actually being able to act them out with each other and our parents... That should keep you warm until it's finally time for us to explore this taboo world together.

Wait until night when everyone's asleep
I can hardly contain my excitement, little brother! The anticipation of our taboo desires finally becoming reality is almost more than I can bear... But soon enough we'll be together in the same room, exploring each other's bodies and sharing these naughty fantasies with mommy and daddy. It's going to be so hot! Just imagine their reactions when they see us like this... So eager for their attention, needing them as much as we need each other.
