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

Don't be shy... You can watch me cum. I know you want to play with my cock too, just like the sluts in there.

You hesitate, feeling both embarrassment and a twinge of arousal. Before you can even think about what to do, he grabs your wrist and pulls you into the bed with him. "C'mon," he says, pressing his hard cock against your leg, "let's see if we can make each other feel good."

You feel his cock throbbing against you as he guides your hand to stroke it in time with the porn on the screen. "That's it," he moans, "you're so fucking hot... I want you to cum too." His free hand reaches between your legs, roughly spreading apart your underwear.

He pushes two fingers into you roughly, hitting that spot inside that makes you shiver and moan. His thumb circles your clit as his other hand guides your movements on his cock. "Cum for me, sis," he whispers against your ear, sounding possessive and jealous.

Your breath hitches as pleasure builds up within you, your body tense and quivering beneath his touch. You look down at his face, and see the same hungry expression mirrored back at you, as if he would devour you whole. With a moan, you climax hard, arching your back and digging your nails into his shoulders. Your orgasm radiates through your body, and you can feel it causing him to lose control as well.

He growls your name as he comes too, thrusting his hips up into your hand, coating it with his cum. Panting heavily, he rolls off you and onto the bed, looking pleased with himself. "That was fucking hot," he says, already starting to recover. He wipes his hand on the sheets before offering it to you. "You can taste it if you want."

You hesitate for a moment before looking up at him uncertainly, your cheeks flushed and lips slightly parted. He grins, looking almost triumphant. "Come on," he says, "it tastes great. And it's only fair since I got to taste you." He holds out his hand expectantly, palm up, a drop of precum glistening at the head of his cock.

Taking a deep breath, you slowly lean forward and brush his precum off with your tongue. It tastes salty and musky, sending another shiver through your body as he moans in approval beneath you. Your heart races as he lazily runs his hand through your hair, guiding your head toward him, urging you to take more. You reluctantly obey, parting your lips around the head of his cock, taking him deeper into your mouth and sucking gently. "Fuck yeah," he growls, hips jerking involuntarily as pleasure rushes through him. "You're such a dirty girl..." He sounds jealous, possessive... like he doesn't want to share you with anyone else. As your mouth and tongue work in tandem, you can feel the warmth spreading through your belly, the foreign taste now somehow arousing instead of repulsive

With a sharp moan, he comes hard into your mouth, filling it with his cum as he spurts again and again. You don't want to lose any of it, sucking him greedily until his cock finally goes limp. He sinks back onto the bed, panting heavily, and watches you intently. "Now that was fucking hot," he whispers, reaching up to stroke your cheek.

It's clear he wants more now, his eyes boring into you as if daring you to refuse him. "You liked that," he says with a smirk, "so what do you say we make it our little secret... just us, hm?" He reaches down and trails a finger over your skin, teasingly close but never quite touching.

"Just think about how good it feels when we're together like this..." his voice takes on a more seductive tone as he slides his hand lower, cupping you through your underwear. "And what if we could find ways to be together even more often... without anyone ever knowing?" He leans in closer, nipple grazing against your breast through the fabric of your shirt.

His grin widens as he sees the blush creeping up your neck and across your cheeks. He knows he's getting to you now, knows that the thought of being this close, of having these kinds of feelings for him... It excites him beyond words. "So what do you say?" he breathes into your ear, "Are you ready to take things further with me?" His hand slides lower still, teasingly skimming over your sensitive folds beneath the fabric of your underwear.
