My name is Ethan, I’m 28 years old, and I live in Los Angeles. My younger sister, Mia, is 25, and she’s a total knockout—34D-sized breasts, a slim waist, and an ass that looks incredible in her tight leggings. We’ve always been close, but lately, I’d caught her staring at me with a hunger in her eyes I couldn’t ignore. One night, she made it clear she wanted my big cock, especially in doggy style, and what happened next was the hottest, wildest night of my life.

It was a warm Saturday night. Our parents were out of town, leaving just me and Mia at home. I was in my room, shirtless in a pair of shorts, when she knocked on my door. She walked in wearing a skimpy tank top and tiny shorts, her breasts practically spilling out and her ass swaying as she moved. “Ethan, can we talk?” she asked, her voice low and teasing. I nodded, and she sat on my bed, her eyes locked on my crotch. “I’ve been thinking about you… a lot,” she confessed, biting her lip. My heart pounded—this was my sister, but the lust in her gaze was undeniable.
