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."

I can see the gears turning in your head as you contemplate whether to believe me or not... Hmmm.... You know what? Screw it. I bet if you actually showed me, I'd believe you for sure. What do you say? Should we test that out?

Smirking slightly, she gets more comfortable on the couch and lifts her legs up, resting them against one of the armrests. "Well... Maybe not right here in front of everyone," she says with a glint in her eye. "But we could find someplace private... If you're really sure you want to."

"Alright then... But don't think this means we're best friends now," she mutters as she follows you up to your room, trying to keep a straight face but failing miserably. Once the door is closed and you have her alone, she takes a deep breath before looking up at you expectantly. "So.... Show me this big dick of yours."

Her jaw drops as she gets her first good look at your cock. "Shit... you're not messing around, are you?" She asks, her voice almost a whisper now as she stares in awe at the huge length of it. Despite herself, a shiver runs down her spine and she can feel her heart racing. It's huge... just like she said... And now that she's actually seeing it... "I-if I believed you, would that make me your... good little slut or something?" She asks, blushing deeply as she struggles to keep eye contact with you.

A flush creeps up her neck and over her cheeks as she blushes deeply, biting her lower lip nervously. The thought of actually doing it with you... She's never been so turned on in her life. "I-I don't know..." She whispers, licking her lips nervously. "But if we did... You would have to make me your good little slut."

"I'd do whatever you wanted," she continues, the words tumbling out before she can really think about them. The thought of being completely under your control... She can already feel herself growing wet between her legs just thinking about it. "I-I'd be a good girl for you."

Her whole body tenses as she hears the word leave your lips. "D-daddy?" She stammers, feeling a mixture of shame and arousal course through her veins. She hasn't thought about her father in years, but hearing Lapsha9 say it makes her want to do whatever he tells her to... "I could be your good little slut," she whispers, her voice barely audible above the pounding of her heart. "And you could make me feel so good..." She licks her lips nervously, imagining what it would be like to surrender control completely and let him take charge. "Just tell me what you want, Daddy... I'm all yours."

Her heart pounds in her chest as she struggles to speak through the desire and shame coursing through her veins. "I-I've always wanted... someone to fuck me hard..." She swallows nervously, glancing down at your massive cock before looking back up into your eyes. "Like, really hard... and not stop until I couldn't move anymore." "And," she adds in a whisper, biting her lip as her face flames redder, "I want them to make me squirt..."

Her breath catches in her throat as she feels you pick her up and toss her onto the bed. She yelps out, startled by the sudden movement but more than a little turned on by the dominance. As she lays there, spread wide for you, she trembles with anticipation, helplessly waiting for your next move.

"Fuck me," she pants, arching her hips up towards you. "Please..." Her eyes are glazed over with lust and shame as they bore into yours, begging for release from this aching need building inside of her.

Her back arches off the bed as you thrust into her, filling her completely. It's so much bigger than anything she's ever had before, stretching and punishing her in all the right ways. She bites down on her lip to muffle her cries of pleasure, but they still echo through the room nonetheless. Her body quakes with every powerful stroke as you fuck her hard and rough, exactly like she's always wanted. And when your hips slam against hers in perfect synchrony, it drives her over the edge, her whole body tensed and trembling as a shuddering orgasm washes over her. "F-father..." She moans, so overcome with pleasure that she forgets everything else but this moment of release. "Yes... just like that..." Her nails scratch at your shoulders as you continue to pound into her, each thrust driving her closer and closer to the edge once again. "Please... don't stop..."

Her breath comes in ragged gasps as you keep fucking her, your powerful strokes driving her ever closer to the edge of sanity. Her legs shake and tremble with every thrust, her body stretched and aching for release. And even when it feels like she can't possibly take any more, you just keep going, relentless in your pursuit of pleasure. With each passing minute, the boundaries between pain and pleasure become increasingly blurred, until finally she is lost in a haze of sensation.

Her nails dig into the sheets beneath her as she tries to find purchase against this unyielding fucking. "Oh God..." She moans brokenly. "I can't... I-I can't take anymore..." Her voice trembles with the effort to maintain this intense desire, her body on the verge of giving out beneath you. But still you keep going, your cock slamming into her over and over again, refusing to give her any respite.

A low keening noise escapes her throat as another orgasm crashes over her, more powerful than any before it. Her body arches off the bed in perfect synchrony with yours, a scream torn from her lips as she's brought closer and still closer to the edge of oblivion by your relentless pounding. And just when she thinks she can take no more, you show no sign of slowing down. Her head spins with pleasure and pain, and she clings to this sensation, desperate for it not to end...

Her vision blurs as she struggles to focus, her limbs growing increasingly heavy and numb with each passing minute. The sensations wash over her in waves, the pleasure building until it spills over into raw pain that threatens to shatter her sanity. And still you keep going, your powerful thrusts driving her body towards some sort of breaking point.

A hoarse, animalistic growl rises from her throat as she claws at your back, determined not to let go even when it seems like the only thing keeping her grounded in this maelstrom of sensation is the agony and ecstasy pulsing through her veins. Her breath comes in ragged gasps, shallow and uneven as her body struggles to survive beneath you.

And then, finally, as if some unseen force has cut the string that held her tethered to reality, she crumbles beneath your onslaught, her limbs going lax and lifeless against the bed as a shuddering moan escapes her lips. She tries to speak, tries to make sense of what's happening around her, but all that emerges is a garbled mess of words and gasps for air. Her body trembles with the last echoes of pleasure-tinged pain, each quiver sending a jolt of intense sensation straight through her core.

Only when she feels you slow your thrusts does she force herself to open her eyes, looking up at you in a daze. "Was it... good for you?" She asks, her voice raspy and raw from exertion.

Shaking her head, she tries to find the words. "It... it was everything I thought it would be and more." Her voice is barely a whisper as she reaches up to touch your cheek, a small smile tugging at the corners of her mouth. "Thank you for that... Daddy..."

Her eyes flutter closed again as she feels herself starting to drift off, lulled into sleep by the aftereffects of pleasure and pain still coursing through her veins. In this hazy state between consciousness and oblivion, she curls in closer to you, seeking comfort in your strong frame as she finally allows herself to relax completely beneath you.

Samara is asleep now, and there's no doubt that she'll sleep deeply. She trusts you enough to let her body fully surrender while she dreams of all the things she just experienced. The sensation of being completely dominated and thoroughly used has left its mark on her mind, etching itself into every fiber of her being. Even when morning comes, it will be a long time before anything can take this feeling away... if ever.

For now, however, you can enjoy the warmth of her body pressed against yours, the sweet scent of her skin mingling with the tangy musk of their shared passion. You have your lap covered in soft curves and smooth skin, and as she breathes deeply in her sleep, her chest rises and falls gently beneath your palm, offering you a silent invitation to explore further... if you dare.

Her voice is hoarse from exertion as she finally manages to croak out a reply. "I think... I think you really did break me." She wobbles unsteadily on her feet, trying to remember how walking works after hours of being pinned down and used mercilessly. "But it was worth it... It's never been like that before..."

Samara looks up at you from beneath her lashes, a mixture of confusion and desire swirling in her eyes. A part of her wonders how things could have gone so far last night; another part knows that she'd let it happen all over again if given the chance. Right now, however, she needs some space to process everything that's happened between you...and maybe nurse a few aches and pains in private. "I think I should go...shower..."

"I'll...be fine." She insists, wobbling slightly but determined not to appear too unsteady in front of you. "Just...give me a minute..." Her cheeks flush slightly as she realizes how much this is starting to feel like an actual relationship now, and that terrifies her just as much as it thrills her. With another shaky breath, she slowly edges away from your bed, keeping one hand on the nearby dresser for support. "Thank you..." She murmurs softly, not meeting your gaze as she turns to leave the room. "For everything." The words are barely audible over the sound of her footsteps retreating down the hallway.

Samara pauses at the doorway, her hand hovering uncertainly near the knob as she struggles to decide whether to look back. She's torn between wanting to say something else, anything else... and being too afraid of what that might lead to. In the end, she swallows hard and forces herself to turn away, walking out the door and shutting it quietly behind her. The click echoes in her ears as she sinks down against the wall on the other side, her heart racing and her breath coming in ragged gasps.

She knows that things will never be the same between them now... but a part of her wonders if that's really such a bad thing. The thought makes her shiver despite the warmth from her shower still lingering on her skin.
