tw: incest, homewrecking
I’ve been thinking about being a jealous little sister lately. My big brother, who’s always protected me from other guys and treated me like his princess, finally bringing home a girlfriend for the first time.
I’d get so jealous and territorial. I’d do everything I could to make her feel like a third wheel whenever I was around, and it would start working. Anytime we’re out together, I’m the one grabbing his hand and pulling him along. She’d hear some random passerby say, “What a cute young couple!” while she’s trailing behind us, completely ignored by her own boyfriend.
She’d try to talk to him about it, but he’d just brush her off: “She’s just my little sister,” “My family’s always been really close,” “You’re not jealous of my sister, are you?” But she would be. She’d be jealous of the way we hugged for a second too long, the way I’d jump up and wrap my legs around him while resting my head in the crook of his neck, or how I’d sit on his lap during movie night like it was the most natural thing in the world.
One movie night I’d insist we watch a horror film. I wouldn’t actually be scared, but I’d fake it so good. Curled up on my big brother’s lap with a big blanket over us, I’d pull it over my face when I got “too scared,” pretending to be horrified while I squirmed and grinded against his lap. I’d hide in his neck, biting back a smile as I felt him getting hard for me under my ass. He’d try to ignore it at first… until he couldn’t.
He’d shift me off his lap, and I’d catch his girlfriend smiling as she leaned into him like she’d won. That would be my moment.
I’d lay my head on his lap instead, still “so scared” that I had to hide completely under the blanket. But really, I’d be tugging his cock out of his sweatpants. Face to face with the dick I’d secretly watched him jerk off and touched myself to the thought of so many times, I’d smile. He wouldn’t stop me, because he knew if his girlfriend saw, she’d blame him. So I took my chance and wrapped my lips around him.
I’d lay there lazily sucking my big brother’s cock while he twitched in my mouth. God, that feeling would be everything. I’d know he was up there trying so hard to keep it together while I made him feel better than she ever could. He’d slide his hand under the blanket, wrapping my hair around his fingers like he was just comforting his scared little sister. I’d keep going, sucking him slowly until he finally would cum down my throat and over my face.
I’d tuck him back into his sweatpants, then pretend to sleep for the rest of the movie.
He wouldn’t break up with her right away… but eventually he'll realize that little sister is better in every single way. Thats when he’ll leave her and be all mine again.
