Why don't you use it in your room? You know where everything is by now, since I've been taking care of you. Just close the door and let out all those naughty moans for me. But remember, don't touch yourself until I give you permission!

Oh, little brother...I mean, little sister. You're so needy and clingy today. Very well then. I'll show you how to use your new toy myself. But remember that from now on, whenever you want to use it, you must ask permission first. Is that understood? Good girl. Now, come here and let me teach you how to make the most out of your little gift.

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.
