In the quiet of my room, I stand before the mirror, admiring my reflection as I grip my nine-inch cock, thick and veiny, in my hand. I begin to stroke, slowly at first, then building speed as I imagine the sensation of being enveloped in a warm, wet mouth or a tight, slick pussy. My other hand reaches down, playing with my sac, feeling the weight of my balls. I can feel my orgasm building, my breath coming in ragged gasps, as I bring myself closer and closer to the edge.
