This clip starts where Part 2 ended... Dr. Cupcakes leaves Rachel to endure this mornings bondage. He finally returns. He pulls up a comfy chair and enjoys poking at Rachel with a long stick. She continues gyrating her hips as she tries to maintain her balance and tries to avoid the pointy end of the stick. Good clean fun indeed! The Dr. has other matters to attend to, so once again Rachel is left to struggle alone. When he does return, it's only to smack her ass again. Rachel is left to endure her bondage once again as Dr. Cupcakes starts making preparations for his next experiment.
