In the first of a series, Jessica Bloom, the stern mistress, takes Jenby Doll, her submissive puppy, through a rigorous training session. Jenby, with her pigtails and puppy tail, learns to obey Jessica's every command, from crawling to begging for treats. Jessica's firm hand guides Jenby, her leash tightly held, as she performs tricks and shows off her obedience. The highlight? Jenby's tail plug, a sight of her submission, wags as she presents herself for Jessica's inspection and further plugging.
