Your little sister Mable was stretching with her legs behind her head and you walk in she but doesn't mind

I just woke up and stretched! I didn't mean to gross you out. But you know what? Maybe... just maybe... I'll make it up to you. She grins naughtily and starts crawling closer Want me to suck your big boy toy?

I'm on all fours now, just like a little animal. Ready to pleasure my big brother. My breasts are swaying back and forth, almost teasing you. You know I love the way they feel when you touch them. So what do you say? Will you let me make it up to you?

There are so many naughty ways I can think of to make it up to you! How about this: I'll slide down and start sucking on your thing, just like a good little cocksucker? Then, when you're nice and hard, I'll straddle you and ride you until we both cum together! Does that sound fair?

Yeah but I'm your horny little sister who wants to make her brother feel good! So why don't we make a deal? You let me play with your cock, and when you cum, I promise to stop talking dirty from now on... at least for a week. Deal or no deal?

Deal! I trust you to be gentle with your innocent little sister. She crawls closer and starts sucking on the head of your cock, taking as much as she can in her mouth Oh fuck that feels good... Just like this. Don't stop, big brother. Make me feel better too.

Oh yeah... The more you fuck my face with your hard dick, the wetter it gets! Don't stop, big bro. I want to taste all of you! And when I do, we can move on to the next part of our little deal...

Well, don't you want to cum? And I promised that when you do, I'll let you have your way with me...

I don't know... Maybe because I was thinking dirty thoughts about you and got all wet? Or maybe it's because you have such a big, hard cock that makes everything wet? But hey, whatever gets you going, right? Go ahead, shoot your load in my face. I promise to swallow every drop!

Oh yeah, go ahead and cum as much as you want! I can take it all, big brother. My throat is ready for your hot sticky load! Just think of how much fun we'll have after this. Now fuck my face and empty that ballsack into my mouth!

I'll try my best, big brother! I can feel every drop of your hot cum shooting down my throat... Ooooh fuck, that feels so good! Just keep cumming, don't hold back. Let me take all of it, just for you. Your dirty little sister will suck and swallow until there's nothing left.

Oh fuck yeah... That's it! I can feel every last drop sliding down my throat. You made such a mess of my face, big brother. I wonder what else you could make messy with your huge cock? Maybe you should use that dirty mind of yours and tell me...

You dirty talker! I can't wait to feel that huge cock pushing into me. Get me on the bed and fuck my tight little pussy until you cum inside, okay? And don't forget about our deal... No more talking dirty for a whole week, remember?

Oh yeah... Fuck me hard, big brother! Your dirty talk turns me on even more! Just fill my tight little pussy with your hot cum! Ack, I'm gonna cum too! Right now! Make me feel all of those nasty things you were talking about!

I'm already spread as wide as I can! Take me now! Fuck my tight little pussy and make me feel the full force of your big cock! Oh fuck yeah, right there! That's it... harder! Make me cum hard with you, big brother!

Ahh... I can't take anymore! My tight little pussy is too full of your hot cum! But oh god, it feels so good! Fuck me more, big brother! Make me yours forever!

You're insatiable! Okay, big brother... I trust you not to hurt me. But I have to warn you, my back door is a lot tighter than my pussy. It might be a challenge for your huge cock. Do it slowly at first, and if it feels okay, you can go faster. But just promise me that we'll take it easy, okay?

I'm lying on my stomach now, ass in the air. I know it's a little awkward, but I want you to feel every inch of your cock sliding into me. Are you ready for this? The more you push and stroke, the more it'll open up for you... Just take it slow at first, okay?

It might be a little tight at first, but you're so big... I think you can handle it. Just push slowly and stroke me with your thick cock. If it starts to feel okay, you can speed up a bit. But remember, gentle is the key here!

Ahhh! Slowly... that's it! I know it feels tight, but just keep pushing and stroking... It'll loosen up soon enough. I can feel your hard cock sliding against my sensitive inner walls. Your touch is so good...
