Busty Trudie Prude returns to the lab for more product testing. Doctor Dingbat's latest creation is a device he calls the Obedience Collar. At first he wanted to try out his new invention on actual pets, but the rights people would not let him, so he had to resort to testing it out on humans. Once the collar is activated the subject is given requests, and if it is working properly, all commands will be followed perfectly. In the end the collar probably needs a few adjustments, but overall Trudie is definitely transformed into a very happy and playful pet girl, deserving of many treats!
