In the quietude of the bathroom, a solo performer finds solace in his rhythmic stroking. The shower's running water provides a symphony of sounds, heightening his senses. His robust cock, already slick with pre-cum, glides effortlessly through his fist, the tight grip mimicking the sensation of a warm, wet mouth. As his pleasure peaks, he feels the familiar tingle in his balls, signaling an impending explosion. With a guttural groan, he unleashes a torrent of cum, the massive load splattering against the tiled wall, leaving a glistening, sticky trail.
