I found myself on my knees, my step sister watching in shock as I took a brutal throat fucking. The dominant stranger gripped my hair, his massive cock splitting my mouth open, stretching my throat to its limit. I gagged and choked, tears streaming down my face, but he showed no mercy, fucking my throat rough and mercilessly. My step sister gasped, her eyes wide with disbelief and fear as she watched me being used like a cheap whore. The room filled with the sounds of my wet, sloppy choking, my cries for mercy ignored. I could barely breathe, my vision blurring as the stranger's thick cock bulged in my throat, ready to explode.
