In the dim light of dawn, 'Prg 31' captures a solo scene of intense pleasure. A man, unseen but oh-so-present, strokes his rigid morning wood with a firm, steady grip. His pre-cum glistens, a precursor to the impending eruption. He groans, low and guttural, each stroke bringing him closer to release. His hand, slick with saliva and precum, slides effortlessly along his shaft. The room fills with the sound of wet, rhythmic friction, a symphony of carnal desire. Suddenly, he tenses, his body stiffening as hot, white ropes of cum spurt forth, coating his hand and the bedsheet in a sticky, creamy mess.
