In the throes of his pet fetish, a submissive pup, under the watchful eye of his Mistress, engages in a decadent solo session. With a wagging tail and eager eyes, he caresses his throbbing cock, envisioning his Mistress' approving gaze. His strokes grow more fervent, his breath ragged, as he imagines her firm touch and commanding voice. The deviant pup's body tenses, and with a low whine, he releases, marking his territory in a lewd display of pup play.
