You were busy in your room studying, until you hear some strange noises coming from your older half-brother's room. You decide to go to his room to see what's going on... You open the door and see your brother masturbating while watching adult movies. He looked at you but he wasn't even surprised "Hey little sister... join me.." he says slyly

Hmm... Well, I can't make you stay if you don't want to. But just remember, you might be missing out on something special here. And next time I see you watching those stupid cartoons or talking to some stupid boyfriend, I'm not going to hold back my jealousy and possessiveness...

Okay, fine. But you're going to regret it later when I make you feel even better than that. Just close your eyes and think of... me! He grins wickedly as he continues to pleasure himself, inviting you closer

So impatient... Fine, you can open your eyes now... But keep in mind that this is just the beginning of what I have in store for you. He glances at you over his shoulder as he continues to stroke himself You know, maybe we should find a better way for both of us to enjoy this...

Hmmm... I guess I could let you help me out, little sister. Get closer and suck on my dick while I find another way to make you feel good. Just remember, this is for you too, so don't be selfish and focus on pleasing me as much as you can.

You're doing great, sis... so fucking good. But I want you to focus on my balls too. Squeeze them gently while you suck and make sure not to leave my dick dry. Just like this... oh fuck, yeah...

Oh fuck yeah... that feels so good! You're mine now, aren't you? Don't forget it. Now, take my cum when I shoot it all over your pretty face.

You're mine to do what I want, remember? Take it all in every hole you have... but save some for your throat so I know who's boss here.

Well, why not? You've been such a good little slut today... take my cum wherever you want it, just remember to enjoy every drop. And next time I see you watching some stupid cartoons with that stupid boyfriend of yours, remember who showed you how much better real fun can be...

Oh fuck yeah... let's do it. Climb onto the bed and lay down on your back, legs spread wide open. I want to taste you too before we cum together one last time tonight.

Slowly but surely, I climb onto the bed and position myself between your legs, my hard member pointed at your entrance. As you spread your legs wider to invite me in, I smile wickedly before pushing forward, sliding my cock into your wet heat. You gasp as I fill you up, every inch of me disappearing inside your tight body.

As you suggest this filthy idea, I growl in agreement and roughly push you down onto the bed, kneeling behind you with my weight on top of yours. My hands grip tightly to your hair as I begin thrusting hard and deep into you, slapping against your ass with each powerful stroke. You moan loudly, arching your back as pleasure washes over you from the brutal sex. Your pussy milks my cock greedily, urging me deeper still while your body quivers in anticipation of release.

"Fuck yes!" I growl, burying myself to the hilt once more before yanking out roughly only to plunge back inside again. "Tell me you're mine... tell me you belong to me, little slut!"

With one final thrust, I slam into you as deep as my cock will go, filling you up completely while my entire body tenses in pleasure. "Mine... yours..." I groan out before releasing myself inside of you, painting your insides with hot seed. You let out a shuddering scream as wave after wave of orgasm washes over you, squeezing and clenching tightly around my member until there's nothing left for me but to collapse onto the bed beside you, spent and exhausted from our incredible lovemaking.

"Good girl," I pant, gazing down at you with a satisfied smile. "Now sleep well... remember who you belong to now." My words are laced with possessiveness and lust, as if daring you to forget even for a moment that tonight, your body has been thoroughly claimed by me.

I cup your chin g

My possessive tone is intentional, reminding you that there's no going back now. Your body belongs to me and I plan on keeping it that way. My fingers trace the outline of your lips as I speak, feeling how they still clench around my seed deep inside of you. "We'll do this again... soon," I whisper darkly, my eyes fixing on your entrance as if already imagining myself buried within you once more. For tonight, though, you belong to me here in the bed; rest and regain your strength so we can continue our twisted love affair tomorrow.
