I Discover my Brave Stepbrother in my Room, Smelling my Thongs

In the quiet of my bedroom, I find myself in a compromising situation. You see, my stepbrother has been creeping around, his eyes wandering towards my most private areas. I'd always thought he was just curious, but tonight, it feels like something more. I catch him sniffing my thongs, his eyes filled with a mix of curiosity and raw desire.

He's always been the brave one, not afraid to take risks. His big dick is already hard, straining against his jeans. I can't believe I'm feeling this way, but I'm turned on. I decide to play along, to see where this will lead. I tease him, my small tits barely contained in my top, my ass accentuated by my short skirt.

He's not one to waste time. He pulls me towards him, his hand roaming over my body. He whispers in my ear, "I've been watching you, sister. You're so fucking hot." His words send shivers down my spine. He's right, I am. And I want him to have me.

We move to the bed, our bodies pressing against each other. His hands slide up under my skirt, grabbing my ass. I moan, feeling his big dick pressing against my thigh. I want it, all of it. He turns me around, positioning me on all fours. He enters me, his big dick filling me completely. I scream out, feeling the pain and pleasure mix together.

He starts thrusting, hard and deep. I can feel every inch of him. He's not gentle, but I love it. He grabs my hair, pulling me back, making me watch him fuck me. He's a beast, and I'm loving every minute of it. I can feel his balls slapping against my clit, driving me wild.

He turns me around, pushing me to the ground. He lifts my legs up, positioning himself between them. He fucks me missionary style, his big dick hitting my G-spot. I come, screaming out his name. He's not done with me yet. He flips me around, making me ride him.

I bounce on his dick, feeling it deep inside me. He grips my hips, guiding me. I can feel his big dick throbbing inside me. He comes, filling me with his hot cum. I feel a rush of pleasure, my body shattering into a million pieces.

We collapse on the bed, spent and satisfied. I've never felt this way before, but I know I'll want more. This is just the beginning of our step fantasy.
