Sarah has been sent to a very strict institution for sexually promiscuous sluts who are nymphomaniacs. Sarah doesn't understand why this is a problem but Miss Matthews is going to make sure to teach Sarah an important lesson. Since the problem remains with Sarah's constantly wet pussy, she must endure lots of pussy punishment to teach the naughty slut to associate pain and humiliation with pleasure and her throbbing wet pussy. Sarah is then told to get on all fours for a strapping to associate more pain with pleasure. The problem is that she only continues to get wetter and wetter so clearly the punishment is not working. That doesn't mean Miss Matthews is going to give up that easily. Oh no! It is time for the final part of the punishment; Sarah will be masturbated until she cums. Hopefully this will really sink the message in that pain and humiliation be associated with sexual sluttiness and masturbation.
