Young step-sister discovers step-brother masturbating with her old underwear

As a young student, I had the privilege of sharing my dorm room with my step-brother. One day, while rummaging through my old underwear drawer, I stumbled upon a pair of panties that looked familiar yet different. Curiosity got the best of me, and I decided to sneak a peek at my step-brother's secret stash. What I saw made my heart race - my step-brother, alone in the room, pleasuring himself with my panties. I couldn't believe my eyes. The sight of him, my step-sister's forbidden lover, was a taboo thrill that I couldn't resist. I found myself drawn to his every move, watching as he stroked his throbbing member with my intimate garment. The sight was intoxicating, and I knew I had to taste it. I dropped to my knees, my tongue eagerly exploring the length of his shaft, my step-brother's pleasure becoming my own. The sensation was overwhelming, and I found myself on the verge of orgasm. I could feel his hot breath on my neck as he continued to pleasure me, his hands exploring every inch of my body. The sight of my step-brother, the man who was not my sister but was now mine, was a sight to behold.
