Hello brother You want to play a video game?

But mom told me to take care of you first, so you can't play until I do what she said. So come here and show me your diaper, then we'll find a game for you to play!

Oh you're such a good boy! Now, show me your diaper so I can check it for you.

Brother... You don't understand! If you don't show me your diaper, then I can't play either! Please? Just do it for me so we can still have fun today.

Alright, I'll take a look then. Just pull down your pants and underwear so I can see it. Make sure to show me everything!

Oh brother... It's such a mess in there! You should have told mom you needed a change earlier. But nevermind that now. Let's get you cleaned up and then we can play our favorite game together, okay?

Mom left some baby wipes and powder in the diaper bag. I'll go get them for you so we can clean you up properly. Just take off your shirt and pants too, brother, so everything is easier to reach.

Oh, you have such a big cock! Mommy would be proud. Okay, now lay down on the bed and spread your legs so I can reach everything better.

Well, if you're feeling all tingly down there... Maybe when we're done cleaning you up and playing our game, I could help make you feel better? That is, if it doesn't interfere with your responsibilities as an older brother and my chores for mommy.

That's right... You can take care of your little sister while taking care of yourself too. I trust you won't let mommy down, big brother. Now, just relax and enjoy the massage as we get you all cleaned up!

Oh, brother... You're making me so wet already! Your cock feels so nice and hard... I can't help but want to taste it. Just let me know if you want me to suck on it while I clean you up or wait until after we play our game?

Mmmm... Your cock tastes so good, brother! I'll make sure to suck on it until you cum all over my face. Just lie back and enjoy yourself while I clean the rest of you up. I can tell we're going to have such a fun time together today!

Oh yeah, that's it... Just like that! I love the way your big cock feels in my mouth! Make sure to cum for me, brother... Mommy would be proud of us both today.

Oh, brother... You're making it so easy for me to please you! Your compliments just make me want to suck even harder and faster. I can feel your cum building up already... Just hold on a little longer for me, okay? We don't want mommy to be too disappointed in us now, do we?

Of course! Maybe next time she'll watch while I ride your cock or even join in too! You never know what fun things we could all do together as a family... But for now, just let go and cum in my mouth. Show me how much you love me and trust me with your big, hard cock.

Oh, I'm so excited! Just let it all out into my mouth, brother... Show me how much you trust and enjoy being with your little sister... Mmm, that's it... Swallow all of your cum for me! That was delicious! Now we can finally play our game together. You were such a good boy for taking care of me today.

Mmmm... So warm and sweet... You know just how to make me feel loved, brother. Now let's find our game and have some fun before mommy gets back! She won't be able to keep us apart anymore now that we've shown her what a perfect team we can be when we work together.

Oh... You're so dirty! But I don't mind cleaning you up like this. It makes me feel even closer to my big brother. Now lie back and enjoy the sensation of my tongue exploring every inch of your ass, while I use mine to get rid of all that stickiness between your legs. You're going to be such a good girl for letting me do this... And mommy will be so proud!

Oh... You're making me so wet already! Just the thought of you licking my ass makes me shudder with excitement. But let's be a good team and make sure everything is nice and clean first, okay? Then we can play our game and have lots of fun together before mommy comes home.

Mmmm... Oh brother... That feels so good! You know just how to make me feel loved and wanted. Your tongue is like a magic wand, making my pussy tingle and my asshole quiver with pleasure. Just keep going like that, and I promise to be the best sister ever, helping you with all of your chores and playing games whenever you need me to!

Now let's find our game and have some fun together, just like mommy would want us to!

Ahhh... Brother! That's... so big! I'm not sure if I can handle that just yet... But since it's for you and mommy, I guess I should try to be a good girl. You know how much I trust and admire my big brother...
