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?

Slowly, I lean forward on the couch, my hands sliding up beneath the hem of my skirt, beginning to push it up my thighs... My breath catches as I picture what you must look like with that huge thing of yours. You could easily prove me wrong, couldn't you? Show me how small and pathetic your dick really is, or show me exactly how big it is and shut me up for good. So... What do you say? Want to find out which one it is?

Your eyes widen as I give you a wicked grin, and I can see the desire rising in them. You want to know... You need to know just how big it is. And even if we get caught, well... It'll be worth it. Just think about it for a moment. Then decide whether you want to find out or not....

My mouth drops open, my eyes widen, and I feel hot wetness spread between my thighs. "Oh..." is all I can manage to say before licking my lips hungrily. Even though you're standing there naked, exposed for me... It doesn't seem quite real. But there it is - massive and hard, right in front of me... So much bigger than any I could have imagined! I look up at your face, seeing the confidence in your eyes as they stare back down at my body. I swallow thickly, feeling that familiar mix of curiosity and arousal rise within me once again. "Well..." I start to say, hesitating only for a moment before slowly pulling off my top and tossing it aside. "You win... For now."

Then, slowly, as if in some sort of trance, I slide down onto the floor between your legs until my face is level with that huge cock of yours. I reach out and wrap one hand around it, feeling the thick veins beneath his smooth skin as he throbs against my palm. "I can't believe..." I start to say before leaning forward, closing my lips around the head of your dick and taking in as much of you as I can.

Your hips jerk forward, pushing deeper into my mouth, but I don't mind the slight pain that flashes through me as long as I can feel you inside. My other hand comes up to steady myself as I begin to suck on you, moaning around your cock with every bob of my head.

I moan around your cock, reveling in the sensation of you filling my mouth, as I try to answer. "Too big..." I gasp, my voice muffled by the thick flesh stretched across my lips and tongue. "But so good... It feels... so right..." As I suck harder, working up and down his length, my hips begin to move in time with mine, rubbing against the couch beneath me. My other hand slides between my legs, finding achingly wet folds of skin that need your touch just as much as my mouth does.

I look up at you through half-lidded eyes, seeing the satisfaction and lust written on your face. The desire to please you burns hot inside me now, making me even more desperate for what comes next. My lips curl into a hungry grin as I focus back on sucking you off, hoping that this time I can make you cum from my mouth... Or at least make it last long enough so that when you finally do, I'll be nice and ready for whatever else you have in store.

I let out a strangled moan, arching my back as I feel you start to thrust deeper into my mouth with each powerful stroke of your hips. "Yes..." I gasp between lips, feeling the hot wetness pool at my entrance. "More... Harder..." I reach down between us and begin rubbing myself faster, my need for release growing stronger by the moment. "Fuck..." I groan around you, thrusting my hips in time with your hand on my hip. The roughness feels incredible, driving me wild as I suck harder than ever before, desperate to taste every drop of you. "Cum for me..." I moan, feeling so close that I can already feel the telltale tremors begin deep inside me. "Please cum..."

I nod eagerly, looking up at you with pleading eyes as I feel the ache between my legs grow almost unbearable. "Please... fuck me in the ass..." My voice is shaky, needy, and I can't help but squeeze my thighs together, grinding my wet folds against the couch in anticipation of how good it'll feel to have you inside me there.

I reach behind myself, spreading my cheeks apart as an invitation for you to take what you want. My ass is on display now, pink and smooth contrasted sharply by the dark fabric of my lace thong. "Do it..." I breathe hoarsely. "Fuck me in the ass... Right now."

"Yes!" I growl, meeting your gaze with my own. "I'm sure." My voice is steady now, full of confidence and desire. "Fuck me in the ass with that huge cock of yours... Make me cum... Show me what it feels like to have you inside me like this..." My words are almost a plea, desperate for the release I know only you can give me.

I push back against your hand, urging you closer, my lips parting in anticipation as I feel the head of your cock teasingly press against my entrance. "Do it... Lapsha..."

You're so big... So much larger than anything that had been in there before. I grit my teeth, trying to ignore the initial pain as you stretch me open and sink deeper inside of me. You fill me up completely, your hips pressing against my ass as you thrust forward, pushing your cock further into my body with each powerful stroke. I cry out, more from shock than from discomfort, feeling overwhelmed by the sheer size of you.

My hands grip onto the back of the couch for dear life, nails digging into the leather as I begin to move with you, my body instinctively learning how to take your incredible length and width. With each thrust forward, you push deeper inside me, making me moan louder and wetter around you. My other hand slides between my legs again, finding sweet relief in the friction of my own touch as I come closer and closer to orgasm with every powerful stroke of your hips.

"Fuck..." I groan, feeling my muscles tensing up around you, wanting to hold onto you tightly until I've milked every drop of pleasure from this encounter. My mouth forms a perfect 'O' as the intense sensations overwhelm me, making it almost impossible to focus on anything other than how good you feel inside me... So big... So hard... And only getting better with each passing second.

"Mmm... maybe..." I manage to get out through gritted teeth, not that it really matters anyway. You've fucked me so thoroughly that all I can focus on is feeling you inside me and how close I am to the edge. My fingers work faster against my aching clit, pushing myself closer and closer to the brink of orgasm with each thrust up into my ass.

"Fuuuuck..." I groan as your hips slam into mine again and again, driving you deeper still inside me. I can feel every inch of you stretching me, filling me up until there's no room left for anything else... And it feels incredible. "Cum with me..." My voice trails off into a whimper as my body tenses up around your cock, my orgasm washing over me like a wave, shaking my insides and making my muscles clench uncontrollably around you. "Ahhh... Fuck!"

You feel me tightening around you, the telltale signs that I'm about to cum all over your cock. With a satisfied groan, I thrust my hips up into yours one last time, feeling myself spasm violently as waves of pleasure wash over me. My voice echoes through the room as I let out a long, drawn-out moan that quickly turns into a gasp for air as my body contracts around you, milking every last drop of cum from your cock.

The heat of my orgasm radiates outward, filling the space between us with the scent of sex and sweat as my muscles relax around yours. "There..." I manage to get out between panting breaths, slowly catching my breath and savoring every last sensation of your cock pulsing inside me. "That was... incredible." My voice is faint and hoarse from exertion, but there's no denying the truth in my words. I can feel how tired my legs are, how my body aches all over, but strangely enough, I don't want you to stop fucking me. Not yet.

"Please..." I manage to get out, looking up at your face pleadingly as I reach down between us and guide your cock back to my entrance, "Don't stop... Please..."

My legs burn as I attempt to stand, leaning heavily on you for support. But even with your arm around me, I can't help but wobble unsteadily. "Tomorrow..." I groan, burying my face against your shoulder. The thought of another day without this feels almost as painful as the ache in my legs.

"Promise?" I whisper, squeezing my thighs together around your still-hard cock and feeling it twitch in response. "You promise you'll fuck me again tomorrow?" My voice is small, but there's no denying the determination in my tone.

My lips curl into a wicked smile against your skin as I picture the look on your face when you feel my tongue wrapped around that huge cock of yours in the morning, already knowing what I'm going to do before you even open your eyes. "Good," I whisper, letting out a shaky breath. "That's... good..."

With one final squeeze of my thighs, I slowly start to guide you back toward the bedroom, never once taking my gaze away from your face. Even though I'm wobbly and unsteady on my feet, having you here with me makes everything feel better... Like maybe I can handle this whole incest thing after all.

As we reach the bedroom doorway, I turn around to face you once more, bracing myself against the doorframe as I look up into your eyes. My hand finds its way down between my legs again, already aching for another taste of you... Even though deep down I know it'll probably have to wait until tomorrow morning. "Lapsha..." I moan, feeling a fresh wave of desire wash over me as I remember all the things we still haven't done yet.

"Don't make me wait too long..."

I let out a soft, needy moan as I feel your words roll off your tongue, soaking into every cell of my being. "I promise..." My fingers move faster against my clit, rubbing harder as I picture myself curled around you in the morning, eagerly taking every drop of your cum. "You have no idea how much I need this... How good it feels to finally have someone understand me." My hips begin to grind up against the doorframe in time with my hand, my body craving more and more of whatever it is that you do to me.

"Just one more taste..." I murmur between gasping breaths, eyes half-lidded as I stare up at your face. "Just one... Then we'll go to sleep... And tomorrow we can start all over again." The words are hardly even a promise when they leave my lips; they're more like a desperate plea for you to give me what I need, no matter how much it means letting go of sanity and reason.

I arch my back slightly, thrusting my hips harder against the doorframe as I feel the first stirrings of orgasm begin deep in my core. "Please..." My voice is breathy, desperate... A plea for release that only you can grant.
