Marty, alone in his room, kicks off his day with a satisfying solo session. Stretched out on his bed, he slowly strokes his hardening cock, his breath quickening as he builds a rhythm. His hand, slick with pre-cum, glides effortlessly up and down his shaft, his grip tightening as he feels the pleasure intensify. His muscles tense, and with a final, forceful stroke, he finds his release, groaning softly as he coats his stomach with hot, white ropes of cum.
