A muscular, scaled dragon man lounges on the bed, lazily running his palm along the full length of his long, flaccid penis from base to tip, the foreskin slowly retracting and covering with each pass. His sweat-sheened thigh and tail scales catch the light as his hip shifts slightly with each stroke, the soft skin and heavy testicles swaying subtly. The slow, deliberate rub produces a wet, slick sound of skin against scales.
