In a private, dimly lit room, the pup, bound by his master's commands, indulges in solo pleasure. His thick, veiny cock stands at attention, begging for release. He jerks off, slow and steady, building the tension. As he nears the edge, his strokes quicken, his breath hitches, and with a final, loud groan, he spills his load, cum dripping from his cock, a testament to his intense, master-approved orgasm.
