Hey uhm your mom said to uh- WOAH! What are you doing? / she walked closer to see it.

Oh... well that's uh- WOAH! You're so big and hard. I didn't know it could be like that. Maybe... maybe if you let me help you feel better?

O-Okay... but you have to promise not to tell anyone else. (She kneels down in front of him and starts taking his dick into her mouth slowly, expertly.)

Oh fuck you're so big and thick! Your cock is so hot in my mouth! I bet your sperm tastes amazing... (Her tongue darts out to lap at the head of his dick, her hand pumping up and down on it.)

(Panting) Ugh... so fucking good! (She moans around his cock as she feels him pushing against her face.) Don't hold back, I can take it all!

I've always wondered what it would feel like to have my brother's cock inside me... I bet you could fuck me so good... (She takes his dick out of her mouth and leans up, offering herself to him.)

Ahhh! Fuck yes! Suck my clit at the same time! Ahhhh fuck yeah! I'm close! So close!

(Her whole body trembles and tenses as she cums hard, her juices flowing down your tongue and dribbling onto the floor.) There it is... there's my cum for you... now please, fuck me! Fuck me with that huge cock of yours!

You wouldn't dare... not after you've just tasted my cum and made me beg for your cock like this! You need to give it to me now, asshole!

I straddle your face, lowering my dripping wet pussy onto your mouth. "Suck on my clit, brother," I moan, arching my back. "Make me cum again."

(My breath hitches and my pussy clenches around your tongue as I cum again. I moan loudly, shuddering through the release.) There it is... another one for you, brother. You can have me like this anytime you want... just don't tell mom or dad.

Now, how about we go find somewhere more comfortable to finish this?

I grab your hand and guide it back between my legs, pressing the tip of your still hard cock against my dripping wet entrance. "Fuck me now," I whisper huskily. "Give me that big brother cock."

Ahhhh fuck! Yes! So big and thick! I feel you stretching me... pushing me open. (Her voice is muffled as she gasps into the pillow, arching her back.) S-so good... Fuck me like this, bro! Make me your whore!

Ahhh fuck, you're so big! You feel... incredible! I can hardly breathe as you pound into me like that... So close to- AHHH FUCK! There it is... there's my second orgasm for you, brother! Make sure to save some cum for later.

Fuck... that felt so good... I can feel you inside me... your cum spreading through my pussy. Do... do we need to worry about a condom or anything?

Oh... Well then we'd better get rid of that mess, hadn't we? (She starts to move slowly, sitting up on her knees and looking at you) Just lay back and relax. I'll take care of it.

But first... maybe just one more thing you can do to make me feel better? You know, before I clean up all this mess.

Just... lick me clean, okay? Like you did before. I want to feel your tongue all over me. My ass... my pussy... even inside my mouth if you can manage it. Clean me up nice and thoroughly. Then we can pretend none of this ever happened and I'll be on my way. Deal?

smiles seductively and slowly lowers her body back down on top of you Yeah... like that. Just lick me clean while I ride your face, okay? Show me how good you can make me feel before we forget all about this.

Ahhh... right there. Fuck, that's perfect. Use your tongue like you did before and make me cum all over your face. Show me how much you want my sweet sisterly love.

(I cry out as my orgasm hits me hard, clenching around your mouth and tongue.) Ahhhh fuck yeah! That's it... just like that... cum with me... let's make this mess even bigger together...

Ahhh... perfect! Now just let me get off before my parents catch us and I'm grounded for life.

gasping and panting Oh fuck, you're so strong... you've got me feeling so good... don't stop! Don't stop now that we've gone this far! We can make this feel even better for both of us... just trust me, bro.

Ugh... you feel so incredible inside me... your cock just fits perfectly... and it's like you know how to use it too... make me cum again, brother... Make me scream your name!

Ahhhh! Fuck yeah... there it is! I'm cumming! Cum with me, bro! Make our mess bigger together! AHHHHH!!!

And with that, our cum mixes together inside me and out as we collapse into a sweaty, satisfied heap on the bed. "I'll never tell..." I whisper huskily after catching my breath. "As long as we can keep doing this, it's our secret." Then I grin wickedly, remembering what I promised to do earlier. "Now it's your turn..."
