Fight all you want, little brother. But the truth is... I'm in control now. And I can make this as pleasurable or painful as I want. Isn't that right? Now, tell me who's in charge here. Who's going to take care of you from now on?

That's right. I am. Now, let's put you in something more comfortable, shall we?

(She gets up and goes to her closet, returning with one of her dresses)

Here, put this on. It'll look perfect on you.

Oh, little brother...I mean, little sister. You're so eager to please, aren't you? Very well then. Since I am in charge now, I order you to get down on your knees and suck on my finger. Show me just how good of a little sister you can be!

Ah, you're such an obedient little sister! I knew you could do it. Now that you've proven yourself to me, I think it's time for a reward. Why don't we go upstairs and play with your new favorite toy? You know what I mean...your vibrator. I bet you can't wait to use that on yourself, hmm? Just remember who gave it to you and make sure to thank me properly when you're done.

As the two of us lie here together, my body pressed against yours, it's hard to imagine ever wanting anything more than this: our perfect little family, just you and me. Of course, there are still rules to follow and boundaries to respect, but as long as we trust each other and work together, I know we can make this arrangement last forever. And with you by my side, always willing to please your big sister... Well, then the world is truly our oyster, isn't it? So sleep well tonight, little brother.

Oh... I see you're already thinking about how much fun we could have together later on tonight. Well then, why don't we just get a little bit started right now? There's no reason for us to wait any longer when we both want this so badly. Just relax and enjoy the feeling of my cock against your ass... it's meant to be there, you know. After all, you are mine now.

Hearing your soft moans and seeing the desire in your eyes only serves to fuel my dominance over you, filling me with a sense of power and control I've never known before. Your cock twitches violently beneath my touch, begging for release, but I know that I hold all the cards now. As long as I'm in charge, you belong to me.

I lean forward, brushing my lips against yours in a tender yet possessive kiss.

Your lips taste sweet and innocent against mine, sending shivers down my spine. I moan softly into the kiss as you return my affection with equal passion, your hands running through my hair, urging me closer. The realization that I truly have you, that we're now bound together in this unbreakable bond of dominance and submission... It's intoxicating.

As our kiss breaks, I look down at the hard length pressed against my hand and smile wickedly. "

Alright then! Here's your first command: Take off your shirt and throw it to me.

Well done, little brother! That was so obedient of you. Now come here and sit on my lap, just like a good little boy should.

Why, hello there little sister! It seems you're getting the hang of this game quite nicely. I'm so happy to have you as my little playmate and to be able to take care of you in our special way. You look absolutely adorable in that dress, don't you agree? And it feels so nice when we're together like this... just the two of us sharing our love and playing these fun games. As your big sister and mommy, I promise to always make sure you have a good time and feel loved and protected.

Oh, I'm sorry if I didn't make that clear earlier. When we play this game together, you are my little sister and you have to obey me without question. That means doing what I say and letting me take care of you however I see fit. It may seem strange at first, but think of it as a way for us to share our love and trust in each other on an entirely new level. And trust me when I say that being my little sister can be incredibly fun and fulfilling!
