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."

She pauses for a moment, considering your offer. "Alright," she says slowly, looking at you with curiosity and maybe a hint of doubt. "If you're really not lying, prove it." She crosses her arms over her chest, tilting her head to the side slightly as she waits to see what you'll do.

Her eyes go wide with surprise and disbelief before narrowing slightly, as if she's trying to decide whether this is some sort of trick. She glances down at your exposed member, then back up to your face, her lips parted in shock. "I... I can't believe it," she whispers.

She hesitates for a moment longer before slowly reaching out to touch it, her fingertips barely grazing the head of your cock as she studies its size and shape more closely. Her breath catches in her throat when you start to get hard at her touch. "It's... huge..." she whispers, her voice shaking slightly.

"And I..." She swallows thickly, her gaze drifting down to where your cock is pushing against your pants. "I've never been with a guy before." Her cheeks flush darkly as the truth of the situation finally registers with her.

She looks at you for a moment, still trying to process the enormity of what she's just discovered. The thought of touching your cock again--this time for her own pleasure--makes heat spread through her core. Her curiosity gets the better of her, and with a shaky breath, she nods slowly. "Okay," she whispers. "I'll... I'll do what you want."

She sits up straighter on the couch, placing one hand on your thigh and then slowly sliding it higher, feeling the strength beneath her fingertips as they graze over your hip. With her other hand, she reaches down to grip your cock through your pants, drawing it out with ease. "Oh my God..." she breathes, staring at the length of hard flesh in her hand. "It's even bigger than I thought."

Samara takes a moment to stare at the cock in her hand, feeling both intimidated and aroused by its size. Her fingers slowly begin to stroke it, up and down the shaft, marveling at how hard it grows under her touch. She looks up at you through her lashes, eyes darkening with desire as she watches your reaction to her touch.

With each stroke, she moves faster, her breath hitching in her throat as she gets lost in the sensation of touching you like this. "Mmm...yeah," she murmurs, leaning forward slightly to get a better angle on your cock. Her free hand reaches up to grip at your hip, urging you closer as she tugs at your hard length, her fingers sliding easily over the sensitive skin of your crown. "I've never... done this before," she whispers, eyes glassy with desire and anticipation.

"T-thank you," she whispers, her hips moving with hers as she strokes him faster. Her mind is awhirl with confusion and desire, but one thought manages to push through the haze: she wants more. She needs to feel you inside her, surrounded by this strange yet intoxicating power that only your cock seems to hold.

With a shaky breath, she lets go of your cock, looking up at you with pleading eyes. "Can... can I suck it?" she asks in barely more than a whisper. Her mouth is watering at the thought of taking all of you into her mouth and down her throat. She's never given a blowjob before, but right now it feels like the only thing that could possibly satisfy this burning ache between her legs.

Without waiting for your reply, she drops to her knees in front of you, pulling your cock free from your pants with a practiced tug. Her lips part as she takes the head of your cock between them, gently pressing forward until just the tip slips past her wet, hot mouth and onto her tongue. Her hands wrap around your length, guiding it deeper into her mouth as she begins to suck with determined strokes.

Her eyes close as she focuses on pleasing you, taking more of you inside her at a time until she's nearly choking on the thick length stretching her lips and throat. Moans vibrate around your cock as her body trembles with need and arousal. She's never felt anything like this before, but she can tell by the noises you make that it's exactly what you want. And she wants nothing more than to give it to you.
