Step Sis Seduces me in Tight Black Dress after her Night Out!

When my step-sis gets home from a night out, she's looking drop-dead gorgeous in a tight, black dress that hugs her curves perfectly. Her big, thick tits are spilling out of the top, and her ass is perfectly accentuated by the dress's cut. I can't help but stare, and she knows it.

She sashays over to me, a seductive smile playing on her lips. "You like what you see, bro?" she purrs, running a hand through her long, dark hair. I nod, my mouth suddenly dry. She leans in, her breath hot on my ear. "I've been watching you watch me," she whispers, before kissing my neck softly. My heart races as she starts to grind against me, her dress rubbing against my cock.

I can't believe she's doing this. But fuck, I'm not complaining. She reaches down, grabbing my cock through my jeans. "You're so hard for me," she coos, before unbuttoning my pants and pulling out my dick. She strokes it slowly, her eyes locked onto mine. "You're ready for me, aren't you?" she asks, a wicked grin spreading across her face.

Before I can answer, she sinks to her knees, her big tits bouncing as she does so. She takes my dick into her mouth, her lips wrapped around the shaft. She sucks me deep, her head bobbing up and down. I moan, my hands tangling in her hair. She looks up at me, her eyes watering as she takes me even deeper.

She pops my cock out of her mouth, spitting on it before taking me back in. She's so fucking good at this. I can feel my orgasm building, but she's not letting me cum just yet. She pulls back, stroking my cock as she licks her lips. "I want to feel you inside me," she says, standing up and unzipping her dress. It falls to the floor, revealing her big, beautiful tits and her wet, fuckable pussy.

I can't resist any longer. I pull her to me, my hands gripping her ass. I lift her up, her legs wrapping around my waist. She guides my cock into her, and I slide into her wet heat. She moans, her head falling back as I start to pound into her. Her big tits bounce with each thrust, her nipples hard and begging to be sucked.

She grinds against me, her body meeting mine with each thrust. I can feel her pussy clenching around my cock, her orgasm building. I know she's close, and I want to feel her cum all over my cock.

I fuck her harder, faster, until she screams out her orgasm. Her body convulses, her pussy milking my cock. I can't hold back any longer. I thrust into her one last time, my cock pulsing as I cum deep inside her. We both collapse, our bodies slick with sweat.

This is just the start of our step-sis seduction story. Stay tuned for more!
