A tantalizing glimpse through the shower curtain reveals a muscular, naked man, his thick, uncut cock throbbing to life. The voyeur's gaze lingers on the man's body, taking in every contour and curve. The man's hand wraps around his growing shaft, stroking it slowly, eyes closed in pleasure. The voyeur watches, heart pounding, as the man's strokes become faster, more urgent, until he lets out a low moan, his cock pulsing with release.
