Stepping out of the warm shower I wrapped the towel around my body and secured it tightly, making my way to the bedroom. Concentrating, I began to make the bed. The sudden sound of approaching footsteps made me turn around, my heart racing with surprise! Standing in the doorway was my step-brother, giving me a tense stare! “Don't look at me, you're my step-brother,” I said, trying to maintain some sense of decorum. As I was adjusting the bedsheet, a towel accidentally slipped off of me. I looked up at my step-brother and saw his eyes greedily taking in every inch of my naked body. His facial expression was filled with desire and inhibitions! Feeling bold and aroused by his presence, I decided to give him a little show! Slowly letting go of the towel, I exposed my body on all sides, teasing him with every movement! I could feel his eyes on me as I moved lower and touched myself, running my fingers over my eager clit and plunging them into my tight hole! I fucked myself in different positions gradually quickening my pace! The realization that my step-brother was watching only increased my excitement, and soon I experienced an incredible orgasm that left me breathless and trembling!
