Mac manages to get a job as a graduate research assistant to Dr White, an attractive older woman who conducts special research in a secret basement location of the university. Mac later discovers the true nature of the research - he learns that Dr White is studying the effects of spanking young women - and even better, he gets to participate. To start with, he is only allowed to listen to the spankings, but as time passes he is permitted to watch them on tape, and later he gets to administer spankings - some of which lead to the release of sexual tension. He becomes quite the expert spanker, quickly getting to grips with hand, paddle, hairbrush and tawse, just a few of the implements used in his dream job. And when the opportunity arises he indulges in a private and unauthorised session with his favourite girl on the project - although he later discovers his 'private' session wasn't as private as he'd thought! Eventually Mac and his favourite girl are taken off the research program, and he discovers a very surprising fact about her.
