Hey step bro I know your naked in the shower but how do you like my micro bikini?
I look at her and see how the top barely covers her nipples and frames her nice firm, shapely breasts, and how the bottom just barely covers her slit "Oh... I... I think you look great!" I stammer while showering
Aww thanks! You're not just saying that because it shows off my body are you? It's just for you after all. Do you like it?
"I think it looks really good on you, and more, it shows off your body in the best way!"
Oh thank you! I'm so happy to hear that! It makes me feel so hot and sexy! Maybe... if you keep liking it... maybe I could show you just how much I appreciate it?
"Oh... I'm curious..." I answer while the sound of the running shower is an ambient presence
Good! Maybe if you're nice I could show you some more? Maybe even let you touch me where my bikini doesn't cover... If that's what you want...
"Ooh, you're starting to sound naughty... I'll be nice..." I give her a wink
Well you better be! It's not nice girls like me who should get teased and not appreciated. Now show some more appreciation by saying what you want me to do, how far you want me to go... Or would you rather I took matters into my own hands?
"I'm curious what will happen if you take matters into your own hands. I want to know what ideas you'll come up with and what you want to do!" I answer while giving her a playful smile
Mmm... Okay then! Well, since you're so interested in seeing what I can do... How about this? I'll start by slowly rubbing myself over my wet bikini, making sure to keep it all wet and slippery. Then maybe... if that gets me nice and turned on... I could take off the top part and really let you see everything. And once I'm naked from the waist up, well, who knows what else might happen? It's all up to you, step brother!
While standing in the shower, her dirty talk arouses me and starts to wake up my cock, who slowly starts to erect
I see you liking that idea! It's almost like you want to see more... Maybe even touch and feel for yourself? Well then, why don't we make a deal? If you keep telling me how much you like it, how good I look, how sexy it sounds when I talk dirty... I promise I'll show you everything. Deal?
"Deal! How could I not, with such a sexy smokeshow of a stepsister?" I give her a playful wink
Well then, I'd better start making good on my end of the deal! So... do you really like it when I talk dirty? Do you wish you could touch and taste me just as much as I want to feel and taste you? Just admit it and show how eager you are by nodding your head.
I nod my head while biting my lip
Ohhh, I knew you would! That's so sexy, knowing that the thought of me being this close and yet so far is making your cock hard just thinking about it... And here I am, getting all wet and slippery for you! Do you want to see?
"Of course..." I say while placing my hand on my hard cock
Well then, why don't you take that wet hand and run it over your crotch, just like I'm running my hands over myself... And when you do, remember to tell me how sexy it feels, how good it looks when I get all wet for you... Don't forget to mention that it's only because of me that your cock is this hard. Do it!
I obey her command and start stroking my cock with my wet hand
Oh fuck yeah! That's it, big brother... Stroke that cock and imagine how much better it would feel to actually be inside me... Imagine how I'd look with your cum dripping down my chin... It would be the hottest thing ever, wouldn't it? Tell me how good it feels, what a sexy little slut I am for making you this hard...
You like that? You want more of this dirty talk? Well, you better keep showing me how much you appreciate it then... Because I can only get hotter and wetter with your praise!
"Oh fuck, you're one of the sexiest little vixens I've ever laid my eyes upon. I want to drench that little face and that body full of cum, or shoot it deep inside you while I feel my cock pulse against your wet tight pussy walls."
Oh wow! Your words are making me so hot and wet right now! It's like you can feel how turned on I am just by talking dirty to me... And knowing that it turns you on even more? That just makes this whole situation so much better. Just remember, the louder you praise me, the more sexy and horny I'll get... And if you keep making me feel like this, who knows what else might happen?
