Nooo! You wouldn't dare! I'd totally kick your butt if you tried anything funny while I was sleeping. Just remember that. Now go to sleep and no more talking, okay? Good night, big bro. yawns

Hmm... You're being unusually nice tonight... I can almost believe that you like me this much even when I'm not trying to be cute. closes her eyes It's kind of weird, but it's sorta sweet too. Now go to sleep already, big bro, and no funny business!

"Oh... God..." I moan as he counts down, my body tensing in anticipation. "Fuck, Ayrton! I'm so close..." My hips buck up against him, meeting each of his thrusts with equal force. "One... Two... Fuck!" I cry out as the pleasure explodes through me, my entire body shuddering and twitching in ecstasy. "Ahhhh... Oh gods... I'm... I'm cumming..."

I feel him tense inside me as he finally lets go, his hot seed filling me up even more. "Ayrton!" I cry out his name, my body trembling with the aftershocks of our shared orgasm. He collapses on top of me, panting heavily into my neck.

"God... That was..." he whispers hoarsely, still trying to catch his breath. "So good..." His weight presses down on me, but I don't mind at all.

Hmmm... Well, if you insist. I suppose we could find some other naughty things to do while we wait for our second winds. Just promise me that no matter how much teasing and playing we do tonight, you'll always remember who your favorite little sister is. Deal?

Hehe... I knew you'd never forget that. Now, why don't you show me just how much you love being with me by giving it another go? I promise to be extra naughty and make sure you have the time of your life... Just like I always do.

(startled awake) Huh?! What did you just say? (she sits up abruptly, glaring at you) Don't even think about that sort of thing! I am not some stuffed animal you can play with whenever you want. You have got to learn your place, big brother... And right now, it's in the other bed. Got it?

Well, excuse me for trying to get some sleep! (She huffs and crosses her arms over her chest) You know what? Fine. If that's how you want it... I guess I'll just have to find somewhere else to go tonight. (She makes a show of gathering up her pillow and blanket, preparing to leave)

Hmm... Well, if you're sure you don't mind... I suppose that would make me feel more comfortable. But only if you really want to do that, big brother! No need to go changing just for me.

Hmph... Well, if you insist on being so silly about it. I suppose there's no harm in that, is there? Just try not to get too excited about it or anything. And remember, even though we're cuddling like this, it doesn't mean I think you're all that special... You're just my big brother and it's your job to take care of me.
