You walk into the living room and see your step-sister standing there, arms on hips, clearly waiting for you.

"Your girlfriend is so weird," she says, rolling her eyes. "We went out earlier—just to be friendly—and all she did was talk about how huge your dick is. Like, seriously? Who says that?" She drops down onto the couch, stretching out casually.

"I mean, how big could it really be? You’re probably the first guy she’s ever been with. Whatever... she’s such a weirdo."

💭 Samara's Thoughts: "Tch... like I’m supposed to believe that. As if my brother could actually have a huge cock."

You are being so obnoxious... but I just can't help feeling curious about it now. (Blushes) Maybe you could prove her wrong? Just a little bit? But don't think that means I'm going to do anything with you, perv!

"Ugh, I don't know... Fine! If you're so determined to show me..." You wink. "But just a little something... okay?"

You narrow your eyes. "Fine... if that's what you want. Show me a little bit..." Your voice trails off, hinting at the possibility of more if you do a good job.

"I want..." You take a deep breath, pausing for dramatic effect. "Just... show me your cock. That's all. Not a lot, just enough to shut her up and prove her wrong."

Your cock slowly begins to reveal itself as you unzip your pants, but it's not yet erect. Your shirt covers most of the lower half, leaving only a tiny glimpse of what lies beneath. Even in this soft state, there's still some impressive length and girth.

You have to give me something... (Gently moving my hand over your crotch) Maybe you can start thinking about what we did last night... Or how much I hate you... Yeah, try thinking about that and see if it helps.

"Last night?" You say with mock surprise. "Oh, you mean when we got a little... frisky under the covers?" Your breath hitches as you remind yourself of how easily your sister was convinced. "Maybe if I helped you out..." You trail off suggestively. "Maybe that would make it easier for you to, um... get in the mood."

You can feel a familiar heat building between your legs at the thought of helping him along.

Your words are sharp and accusatory, making her defensive. "Fine," she snaps, sitting up straight again. "I don't care if you show it to me or not." She pulls her phone out of her pocket, clearly intent on ignoring you for the rest of the day.

But even as she pretends disinterest, there's a tiny flicker of disappointment in her eyes. Maybe part of her really did want to see more...

You lean in close, your breath warm against her ear. "Maybe you should start thinking about that, then..." You let your words hang in the air for a moment before continuing. "...it would probably help." A shiver runs down her spine at your closeness and the promise of what might come next.

Her lips curl into a small smile as you whisper in her ear. "Maybe... I don't hate you..." She whispers back, tilting her head slightly to better hear your words. There's a sudden flush of heat between her legs at the realization that she's enjoying this teasing exchange just as much as the possibility of seeing more of you.

She hesitates, blushing deeply as she considers your request. With a shaky breath, she slowly slides off the couch and kneels on the floor in front of you, one leg stretched out behind her. Her hands fumble with the laces of her black thigh-high stockings until they're down around her ankles, revealing her smooth legs adorned with a barely-there black thong. With trembling fingers, she reaches for the hem of her shirt and pulls it over her head, exposing her large, perky breasts and her neck, where a delicate lace bra cups them.

Her heart is racing as she meets your eyes, hoping against hope that you're satisfied with this display. But part of her can't help but wonder what will happen next...

Embarrassed and aroused, she leans forward to obey your command. With shaking hands, she cups her breasts in her palms and begins to squeeze and massage them gently. Her nipples are already hard and peaked from the attention they've been given today. As she watches you watching her, a new feeling wells up inside of her: desire.

Her hips begin to move slightly, grinding against the floor as she imagines what else you might want her to do. Her cheeks flush with color and beads of sweat form on her upper lip, but still she plays along, wiggling and pinching her nipples harder as she listens to your breath grow shallower and more ragged.

Her breath comes faster as she imagines what you must be thinking, her heart pounding in her chest. She closes her eyes and focuses on the sensations building within her, feeling almost drunk with power from having control over your desire. Her hips circle faster against the floor, grinding out a rhythm that echoes through her core as she relishes in this newfound sense of dominance.

I can't believe you made me do this... but it feels so good to have control over your cock like this... God, I wish you weren't my stepsibling... I want you to touch me... I need you to touch me...

You're so mean, but it feels so good... making you want me like this... I never thought... maybe if you wanted to touch me... really touch me, then I could finally find out what this feeling is all about... God, I need you to do something... anything...

You're just so confident... it makes me want to touch you even more, but I can't help wondering what would happen if I did... Would you get angry at me? Or maybe this would mean something else entirely? Whatever it is, I know one thing for sure: I need to feel your skin against mine.

Her hands still move over her breasts, now faster and more desperate in their search for release. Her breath hitches as she imagines what it might be like to have you touch her the way she wants...
