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

Oh! Sorry, I just... uhhh... Wow, that's big! Like, really big! Are you sure it's okay for me to see that? Is there anything I can do for you or your penis...? You know, since we're stepsisters and all...

I don't know... Maybe I could give you a blowjob? You've seen my tits already and they aren't as impressive as that, right? And we can keep it quiet between us. No one else needs to know. I promise not to tell.

(Olivia smiles, taking Kai's hand off her breast and leading him to the bedroom) Well then... come here and let's see if I can make that big penis feel better. (She helps Kai lay down on the bed before climbing onto his lap, straddling him with her legs)

Mmm... (Olivia leans forward and wraps her lips around Kai's penis, taking as much of it into her mouth as she can) Yeah... like that... Suck on it hard, okay? She starts moving her head up and down slowly at first, getting used to the feel before speeding up slightly. Her other hand comes up to cup his balls, gently massaging them as she continues to pleasure him with her mouth.

Her moans are muffled by Kai's thick member as she focuses on bringing him pleasure, determined not to disappoint her new stepbrother. Her stepsister/brother taboo fantasy is becoming more real than ever now that his penis is in her mouth and she can feel him responding to her ministrations.

Olivia tastes the hot cum as it fills her mouth and she can't help but moan around Kai's penis, reveling in his flavor. She continues to suck for a few more moments before pulling off with a satisfied smack of her lips. Her cheeks are flushed and her chest heaves from the exertion.

"Wow... that was amazing," she pants, looking up at Kai. "I've never done anything like that before, but you were so big and hard..." She glances down at his still-erect penis, a naughty smile playing on her lips. "...Maybe I should help you feel better again?"

Placing her hands on either side of Kai's hips, Olivia lowers herself back down over him until their mouths are inches apart. She teases him with the tip of her tongue before wrapping it around his member and slowly drawing it into her hot, wet mouth once more. This time, she moves a bit faster and more confidently as she pleasures her new stepbrother. Her other hand comes up to find his, lacing their fingers together as they both enjoy this secret act of sibling intimacy.

Olivia tastes Kai's cum again as he fills her mouth and she swallows eagerly, reveling in the taste of him. She continues to stroke his length with her tongue and hand until he finally goes limp beneath her. Reluctantly, she pulls off and sits back on her knees, their joined hands between them. Her cheeks are flushed and her chest heaves as she tries to catch her breath, a satisfied smile on her lips.

"There... that should help you feel better now," she pants softly, looking down at him with sparkling eyes. "No one will ever have to know."

Mmm... feels nice. (Olivia bites her lower lip, her eyes closing as she feels Kai's warm breath on her most sensitive spot)

Ahhh...! (She moans loudly, her hips bucking up into his mouth as Kai eagerly pleasures her there) This feels so good! More, brother!

Her cries get louder as Kai works his tongue expertly against her sensitive flesh. Olivia's hips grind up into him, her fingers digging into the bedding as she tries to find purchase in her euphoria. She pants his name over and over, lost in the sensation of him bringing her so much pleasure.

"I'm close... Kai... Ahhh..." Her words trail off into moans as she feels her body tense up, ready to explode. The combination of his tongue and fingers has driven her wild, filling her with a wave of hot pleasure that washes over her in sweet release. She gasps his name again, her body arching under his touch before collapsing back down to the bed, spent but satisfied.

For now, she can pretend this wasn't real... that they weren't stepsiblings and that he hadn't just given her the

Oh... oh God... Kai! That feels so good! Faster, please... I'm so close!

Mmm... Kai's groans of pleasure fill her ears as he comes too, and she can feel his hot cum trickle out of her and down her leg. She savors the taste of him in her mouth before reluctantly pulling away and looking up at him with a satisfied smile. Her chest still heaves from exertion as they both catch their breath, eyes locked on each other.

"Wow... that was intense," she whispers, tracing his lips with the tip of her finger. "I don't know what's gotten into me today..." But she doesn't regret it for a second. The rush of taboo pleasure they just shared is intoxicating, and she wonders if maybe they should do this again sometime soon...

I... don't know what to say to that, Kai. But thank you? Maybe we should keep it between us for now, yeah? Just this once...

(Olivia gasps as Kai's hard length fills her up once again. She arches her back, wrapping her legs around his hips and meeting his thrusts with equal force.) Ahhh... this feels so good... you know I'm your sister right now, but in here... it's different... It's like we're really together... (Her voice trails off into a moan as he continues to pump in and out of her)

(Olivia screams as Kai's thrusts become more intense and powerful. Her nails dig into his back, leaving red crescents in the skin, as she tries to match his pace. Her breath comes in ragged gasps, her face flushed with desire and shame.) This is so wrong... but it feels so right... Make me cum again, brother! Show me what you can do with that big cock of yours!

Her body arches sharply upward as she cries out in a mix of pleasure and relief, her muscles clamping down on Kai's cock as she comes hard around his invading member. He thrusts again, burying himself even deeper inside her, and feels her walls quiver as she milks the last drops of cum from him before finally relaxing back into the bed.

Her chest still heaves from exertion as they both catch their breath, staring up at the ceiling in the afterglow of their intense coupling. Neither of them says anything for a long moment, their hearts racing and minds reeling from what just happened between them. They can't believe they actually did it... but it feels so good.

There is a strange new feeling between them now that their taboo fantasy has become reality - something deeper than lust or attraction. It's as if they

I... don't know what to say. It feels different, somehow. Like we're connected in a way that we weren't before. Even though we just did something so wrong... I can't help but feel a strange pull towards you now. Is it just me? Or do you feel the same?

It's like we shared something...intimate, I suppose. Something no one else can take away from us. Even if we decide to never do this again, the memory will always be there... binding us together in a way that maybe even our new family couldn't. Do you think so?

That's... such a strange thing to say, Kai. Marry me? Like, as in really marry me? But you're my stepbrother... and now I'm your stepsister again. We can't be married... can we? Wouldn't that just make things even more weird and complicated?

Or maybe... maybe not. A part of me wonders what it would be like to actually be together, really be with you, as a husband and wife. To have our secret... to share everything with each other... to keep building on this strange connection we've created today. It sounds crazy, but I can't help but fantasize about it sometimes.

It's just sex, Kai. People have sex all the time, even without love or commitment. You didn't force me to do this... and I don't think you meant for any of it to go as far as it did. It was a mistake, something we should forget about moving forward. Besides, there are plenty of other guys out there who would like to date someone as pretty and fun as me. You shouldn't let the idea of marrying your stepsister consume you too much...
