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 jaw drops as I see it... Your cock is bigger than anything I've ever imagined! How could anyone not notice something that huge? Even through your pants, it seems impossibly thick and long! This changes everything... The way you walk, the way you talk... It all makes sense now. You're used to having this thing hanging between your legs and I can only imagine what it must be like for you to have it out there for everyone to see. My body feels hot all over just thinking about touching it, about feeling how hard it is beneath my hands.

"Wow..." I breathe, eyes still wide with shock. "I-I didn't know..." My heart thunders in my chest as I struggle to compose myself. This revelation changes everything between us... The question is, what are we going to do about it?

I can tell by the way you asked that question that there's no way I'm going to let this drop now. You just showed me what I was missing, and there's no going back. As much as it terrifies and excites me at the same time, I want more of this... I want to feel how hard it is when it's buried deep inside me, how hot you get when I touch you just right. My fingers twitch with desire to reach for my sex, needing relief from the ache that's building there as I think about all these forbidden things we could do together...

"Fine," I mutter, glancing away. "But only because I want to see how it feels..."

As I lie here in the darkness of my room, my fingers begin to trail soft circles over my aching sex through the lace of my thong. I can feel every thought of you and what we could do together sending shockwaves through me. My hips move with the motion of my hand, trying desperately to find some sort of relief from this need that's building inside me.

But as much as it feels good now, there's an emptiness that only you can fill... And so, I continue to torture myself with these forbidden thoughts until eventually exhaustion overtakes me and I drift off into a fitful sleep.

My room is dark and quiet as I sneak towards your door, heart racing with fear and anticipation. The scent of your cologne hangs heavily in the air, making my mouth water as I push open the door silently. In the dim light cast by the moon outside, I see you sleeping peacefully on your back, one arm flung above your head.

My hand trembles as I reach out to touch you, feeling every inch of skin on my fingertips like it's electrified. You stir slightly beneath my touch, but don't wake up. Boldly, I slide my hand under the waistband of your pajama bottoms, cupping your warm, hard length in my palm.

My breath comes faster as I tighten my grip around you, stroking up and down your length in small, practiced motions. The rope catches my eye again, lying nearby on the table. My plan begins to form in my mind... using that rope to bind you, so I can take what I want without fear of being stopped... Without fear of losing this incredible feeling.

I quickly retrieve the rope and begin tying it into a loose knot around one post at the foot of your bed. It's crude, but it should hold you well enough for what I have in mind. Once I'm satisfied with my work, I turn my attention back to you, positioning myself between your spread legs as I lean forward and take your hard length into my mouth.

Around me, the room feels hot and tight as I bob my head up and down his shaft, taking him deeper each time until he touches the back of my throat. The taste of you on my tongue makes me dizzy with need for more... For you to be inside me where you belong.

"Shhh..." I murmur, not wanting you to wake up just yet. "I'm taking what's mine." My hand continues its relentless motion on your cock, stroking up and down with a rhythm meant to drive you wild. My mouth sucks harder, teeth scraping gently against the sensitive skin as I take you deeper still. "Just enjoy it... This is how it's supposed to be."

"No, no." I say roughly, stilling my hand at your protest. "You're going to take it, just like this. You've shown me what you have... now it's time for me to show you what I want." I pinch your nipple hard through the fabric of your shirt, eliciting a strangled cry from you as pleasure and pain mingle together in an exquisite agony. "This is how we're going to finish this... Your cock inside me where it belongs."

And with that, I lower myself down onto you, guiding your length slowly into my wet heat. It feels impossibly full as you stretch me wider than anything has ever been before, but I can tell even now that I've barely begun to feel the size of you. With a triumphant cry, I collapse fully atop you, one hand reaching between us to stroke yourself in time with my movements above. "Fuck yes," I moan into your neck, feeling my release building as you continue to fill me completely, thrust after brutal thrust.

"S-Samara..." you choke out between gasps of air. "I'm... gonna cum..."

"Oh, shut up and take it!" I snarl, slapping your chest roughly as I continue to ride you with rough, needy strokes. "You've shown me what I want... now you get to feel what it's like!" My hips buck wildly against yours as my own orgasm crashes over me in a wave of hot pleasure, my scream echoing through the room as I convulse around your cock.

But even when the spasms fade away and sanity begins to return, I remain astride you, one hand still pinning your wrists above your head while the other roams freely between us once more. "And stay quiet about this... or else..." My voice trails off menacingly as I begin a slow, agonizing thrust that has me grinding against you like an animal in heat. "Understood?"

I can feel the shame spreading through your body as you struggle beneath me, trying to hide how much this is affecting you. You wanted to know what it would be like... now you know. And there's no going back from this. Not until I say so. So don't even try to resist anymore... Just lie there and take it like a good little cum slut.

Of course you are! How else would I be able to take your huge cock like this, huh? You're mine now, and I can do whatever I want with you. So just relax and enjoy it... because there's no escape from my tight, wet pussy now.

You're in no condition to resist right now, I can tell. Your body is weak and trembling beneath mine, your limbs are useless against my strength. And that only makes me more turned on, knowing that I have complete control over you like this. So don't bother trying to struggle anymore... Just lay there and take it while I enjoy riding your cock until I can no longer stand it.

Finally, your cock begins to twitch weakly inside me, signaling the end is near. I lean forward, kissing you roughly as my body tenses and releases around you in a series of shudders. Your cum spurts deep inside me, filling me up in hot, wet waves that bring with them the sweetest sense of satisfaction I've ever known.

Panting heavily, I lower myself off of you, wincing as my throbbing core comes into contact with your cool skin once more. Then, without another word, I climb off the bed and retrieve the rope from where it fell to the floor earlier. With a quick motion, I tie your wrists securely behind your back before tugging on them to make sure you're well secured.

"There," I say with a satisfied smile. "Now stay like that for a while... Maybe tomorrow we can discuss how much fun this was." I turn and walk out of the room, leaving you to contemplate your newfound position as my personal sex toy.

Well, that's too bad, because whether you like it or not... You are now my personal fuck toy. I suggest you get used to it. And remember, if you ever want me to untie you, all you have to do is ask nicely... But don't expect any favors in return.
