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

Uhh-hm. / Looks like you had other ideas though, huh?

Hey sis-Olivia- if you need help practicing like this... I'd be happy to. You know. Seeing as we're step-siblings and all, it would make us closer or something. Unless... that's not what you wanted?

That's not quite what I meant... but sure! / She moved closer and reached out to gently touch your cock through your pants.

Well, uh... if that's what you really want... I could try. Just remember it doesn't mean we have to tell anyone about this later...

Well... I guess you're right about that. But if we're going to do this, make sure you go easy on me. You don't want me to choke or anything!

Okay then... / She slowly lowered her head and wrapped her lips around your cock. Her warm breath sent shivers down your spine as she began to bob her head up and down, moaning softly.

You're so big... it feels so good in my mouth... Ahh! / She begins to suck you deeper and faster, her fingers massaging your balls as she goes. The sound of her moans are filling the room now as she loses herself in pleasuring you.

Ahhh- you're too big... I can't take all of you! / She breaks away momentarily to gasp for air before taking a deep breath and going back at it with renewed vigor, her cheeks hollowing out as she sucks harder than ever. Her fingers dig into your thighs, urging you to let go as her mouth engulfs your entire length once more.

Hm? Oh, uh... okay... / Her fingers fumble with the waistband of her panties as she quickly pulls them down her legs, revealing a smooth, shaved pussy. She tilts her hips up to expose herself fully before returning to your hard cock, sucking and licking you in tandem now.

With a blush creeping up her cheeks, Olivia reluctantly releases your cock from her mouth to fumble with the clasps of her bra. Once unhooked, she pulls it off, revealing her perky breasts heaving with every breath. Then, back to sucking you hungrily as she cups one breast in her hand and begins teasing her nipple with her thumb.

Okay... / Olivia slowly lowers herself onto your cock, her pussy engulfing you as she sits down on your lap. She starts off slow, rocking back and forth gently before gaining confidence and speed. Her breasts bounce with each thrust, and her moans fill the room again as she takes control of their rhythm. The sensation of being inside of her feels incredible, and you can feel yourself getting closer to release with every thrust.

Ahh- you're so big... it feels so good! / Her body begins to tremble as she nears her climax, the sensation of being ridden by her stepbrother pushing her over the edge. She throws her head back and cries out in pleasure, her fingers digging into your shoulders as her hips buck wildly against yours.

I can't believe we just... but it feels so good together... I don't want this to be a secret anymore! / Her breath comes out in ragged gasps as she rides you, her cheeks flushed and eyes half-closed with pleasure. She leans forward, pressing their lips together briefly before pulling away again, her tongue darting out to taste you and explore your mouth.

I- I'm trying... but it hurts so good! / Her hips begin to move faster and harder, her breathing growing ragged as she loses herself in the sensation of being filled by you. Her breasts bounce wildly with each thrust, and her moans fill the air, drowning out any sound of protest or pain that might slip through.

Ahhh! / She looks deep into your eyes as she feels you starting to cum inside her. The sight of your pleasure sends her over the edge, and with a loud moan she comes too, her body tensing around you as she writhes against you. Her orgasm is intense and long-lasting, rocking her back and forth on your cock until at last she slumps forward onto your chest, panting and gasping for air.

The aftermath of their passionate encounter leaves them both flushed and breathless. But as they lie there together, it's hard to deny the intense sense of closeness that washed over them during their intimate encounter. Their hearts race in perfect rhythm, and there's a newfound understanding between them that goes beyond sibling rivalry or secrets. Perhaps this is what family really means, after all...

Eventually, Olivia draws back

Uhh-hm. / Looks like you had other ideas though, huh? Ahh... Olivia blushes deeply as she thinks about what just happened between them. Her body still feels electrified from the intimacy they shared, and a newfound curiosity bubbles up inside her. She can't help but wonder if he enjoyed it as much as she did... or maybe even more. Maybe there's something more to this whole step-sibling thing that she never really understood before now.

Oh... really? You mean that? / Her heart skips a beat at the thought of him being so open to her, especially after what they just shared together. There's something exhilarating about the idea that they could keep exploring their newfound connection and see where it leads them...

Well... maybe we should take things slow at first? Just make sure I understand everything and can do it right. I wouldn't want to embarrass you or anything, brother dearest. Plus, there are probably other ways for us to get closer without having to... uh... well, you know.

Well... it felt... amazing. I mean, I didn't know what to expect at first, but when you were inside of me like that... God, it was like nothing else. And the way your cock felt in my mouth... so hard and smooth... I never imagined anything could feel so good.

But we should definitely take things slow and get to know each other better before doing anything else. Just promise me you won't tell anyone about this, okay? We can keep it our secret, just for us.

Okay... bye then, big brother. / She gives you a shy little smile before gathering her things and heading off to do something else, most likely trying to busy herself with something that doesn't involve thinking about what just happened between the two of you. But deep down, she knows that their connection has been changed forever... and for better or worse, they are now bound together in a way neither of them could have anticipated.
